2.1.1 Generally.

Neither Parent, Intermediate nor Merger Sub shall, and the Investors shall not permit Parent, Intermediate or Merger Sub to, determine that the Closing Conditions have been satisfied, waive compliance with any covenants, agreements and/or Closing Conditions contained in the Transaction Agreements, amend, supplement, modify or terminate any Investor Commitment Letter or any Transaction Agreement, assign any rights or obligations under any of the foregoing, determine to close the Merger or the transactions contemplated by the Securities Purchase Agreement, or take any other action with respect to, pursuant to or in connection with the Transaction Agreements or any of them, in each case unless such action has been approved in writing in advance by the Requisite Investors. Notwithstanding the foregoing, (x) MD shall have the sole and exclusive right to cause Parent to terminate the Merger Agreement pursuant to Section 7.1(d)(iii)(A) thereof, (y)

Parent shall, and the Equity Investors hereby irrevocably consent and agree that Parent shall, terminate the Merger Agreement pursuant to Section 7.1(d)(iii)(A) thereof immediately upon receipt of written notice by MD to so terminate the Merger Agreement and (z) MD agrees not to cause Parent to terminate or otherwise provide the Equity Investors written notice of termination in accordance with the foregoing clauses (x) and (y) unless and until Parent is entitled to terminate the Merger Agreement pursuant to Section 7.1(d)(iii)(A) thereof.

2.1.2 Certain Matters. In the event that the Company provides Parent, Intermediate or Merger Sub notice pursuant to Section 5.3(f)(i) of the Merger Agreement, (i) the MD Investors and the Equity Investors shall promptly and in good faith discuss whether to make adjustments in the terms and conditions of the Merger Agreement and the Financing as would permit the Company and the Special Committee or the Company Board not to (x) effect a Change of Recommendation or (y) allow the Company or any of its Subsidiaries to enter into any Alternative Acquisition Agreement with respect to such Superior Proposal and (ii) to the extent that the Equity Investors desire to, the Requisite Investors shall cause Parent to promptly and in good faith discuss and negotiate with the Company and its Representatives (as defined in the Merger Agreement) to make such adjustments. In connection therewith, if, during or after such discussions and negotiations between and among the Equity Investors, the MD Investors and the Company, the Equity Investors inform the MD Investors in writing that (A) the Equity Investors desire to make such adjustments, (B) the Equity Investors have, or have arranged, the necessary incremental equity or debt financing to do so (including proposed amendments to the Debt Commitment Letter) (it being understood that the MD Investors shall not be obligated to commit additional equity financing in connection therewith), (C) the valuation of the Rollover Shares for purposes of the contribution of such Rollover Shares to Parent for shares of Parent Common Stock in any such proposed amended agreements (the “Proposed Amended Agreements”), as a percentage of the purchase price to be paid per share of Company Common Stock in the revised merger proposal, is no less favorable to the MD Investors than the valuation of the Rollover Shares in connection with the Superior Proposal set forth in the notice pursuant to Section 5.3(f)(i) of the Merger Agreement, as a percentage of the purchase price to be paid per share of Company Common Stock in such Superior Proposal, and (D) such Proposed Amended Agreements are otherwise the same as the Denali Agreements as in effect on the date hereof other than for such adjustments as are necessary for the Company and the Special Committee or the Company Board not to take the actions contemplated in clauses (x) and (y) of the immediately preceding sentence, if the MD Investors inform the Equity Investors that they desire to make such adjustments on the terms described above, then, unless the MD Investors inform the Equity Investors that they have determined that the purchase price per share of Company Common Stock to be proposed in such revised merger proposal is higher than the highest per share price at which they are willing to provide equity financing for an acquisition of the Company, Parent, the Equity Investors, the MD Investors and MSDC Investor shall submit a revised proposal to the Company on such terms and, to the extent such revised proposal is accepted by the Company, enter into all necessary agreements to effect such revised proposal and the transactions contemplated thereby. Except for the restrictions contained in the Voting Agreement as in effect on the date hereof, the MD Investors shall not enter into any agreement that prevents them, prior to termination of the Merger Agreement, from (i) entering into or

conducting discussions or negotiations with the Equity Investors, (ii) modifying or changing their agreements, arrangements or understandings with Parent and/or the Equity Investors or (iii) participating in any proposal to modify the terms of the Merger Agreement or agreeing to any such modification.

The terms of the definitive agreements providing for the Debt Financing shall be subject to, and Parent shall not enter into such definitive agreements without, the approval of the Requisite Investors. The Debt Commitment Letter may not be terminated by Parent or any of its Subsidiaries without prior written approval of the Requisite Investors.

2.3.1 Subject to Section 2.3.2, the Requisite Investors may cause Parent and/or the Surviving Corporation to negotiate and enter into definitive agreements with certain members of management of the Company and/or its Subsidiaries with respect to the terms of such management member’s employment, compensation, bonus and incentives, rollover equity and/or equity incentives at and following the Closing on such terms as the Requisite Investors may approve; provided, that for the avoidance of doubt, no commitments or agreements with any member of management of the Company and/or its Subsidiaries may be entered into without the prior written consent of the Requisite Investors.

with such additional or modified terms as the Requisite Investors may mutually agree and (ii) until such time as the Stockholder Agreement Documents may be executed and delivered by the Investors and Parent, each Investor and Parent agrees that the terms and provisions set forth in Exhibit A shall be binding on, and shall govern with respect to the matters set forth therein and that each of such parties will comply with all of the terms set forth on Exhibit A.

Parent shall not attempt to enforce the Equity Investors Commitment Letter, the MD Investors Commitment Letter or the MSDC Investor Commitment Letter until the conditions set forth in this Section 2.6.1 have been satisfied. Subject to the foregoing provisions of this Section 2.6.1, Parent shall have no right to enforce the Equity Investors Commitment Letter, MD Investors Commitment Letter or MSDC Investor Commitment Letter unless directed to do so by the Requisite Investors in accordance with this Section 2.6.1.

Notwithstanding anything herein to the contrary, prior to the Closing and for a 180 day period thereafter, each of the Equity Investors, the MD Investors and MSDC Investor shall have the right to assign, transfer and syndicate (the “Sell-Down”) a portion of its equity commitment to one or more investors in accordance with this Section 2.6.4 and the section of Exhibit A titled “Sell-Down”.

MSDC Investor Commitment Letter, the Voting Agreement and the agreements listed on Section 4.8 of the Parent Disclosure Letter, there are no contracts, undertakings, commitments, agreements, obligations, arrangements or understandings, whether written or oral, between such Investor or any of its Affiliates, on the one hand, and any beneficial owner of outstanding Shares or any member of the Company’s management or the Company Board, on the other hand, (i) relating in any way to such Shares, the transactions contemplated by the Merger Agreement, or to the ownership or operations of the Company after the Effective Time, or (ii) prohibiting the parties to the Voting Agreement from taking the actions described therein.

2.13 Waiver of Appraisal Rights; Further Assurances. Each MD Investor hereby waives any rights of appraisal or rights to dissent from the Merger or demand fair value for its Rollover Shares in connection with the Merger, in each case, that such MD Investor may have under applicable law, including pursuant to Section 262 of the DGCL. From time to time, at Parent’s request and without further consideration, each of the Investors shall execute and deliver such additional documents and take all such further action as may be reasonably necessary or desirable to effect the actions and consummate the transactions contemplated by this Agreement. Each of the Investors further agrees not to commence or participate in, and to take all actions necessary to opt out of any class in any class action with respect to, any claim, derivative or otherwise, against Parent, Intermediate, Merger Sub, the Company or any of their respective successors relating to the negotiation, execution or delivery of this Agreement or the Merger Agreement or the consummation of the Merger.

2.14 Regulatory Matters. Each Investor will use reasonable efforts to supply and provide information that is complete and accurate in all material respects to any Governmental Entity requesting such information in connection with filings or notifications under, or relating to, applicable laws that are required as a result of the Merger Agreement, the Securities Purchase Agreement and/or the related financings and transactions.

2.15 Contribution With Respect to Limited Guarantees. The Investors shall cooperate in defending any claim that the Investors are or any one of them is liable to make payments under the Limited Guarantees. Subject to Section 2.16, each Investor agrees to contribute to the amount paid or payable by any other Investor in respect of the Limited Guarantees so that each Investor will have paid its Funding Percentage of the aggregate amount paid under all of the

Limited Guarantees; provided, that it is understood and agreed that no Investor shall be obligated to pay an amount pursuant to its own Limited Guarantee and the terms of this Section 2.15 that, in the aggregate, exceeds the applicable maximum amount it is obligated to pay pursuant to its own Limited Guarantee.

2.16 Indemnification. In the event that (i) the Merger Agreement is terminated and the Parent Termination Fee and/or other losses or damages are paid or are payable pursuant to the Merger Agreement by or on behalf of Parent, Intermediate or Merger Sub or any amount is payable under any Limited Guarantees and (ii) either a MD Investor’s, MSDC Investor’s or an Equity Investor’s breach of their respective express obligations under the Investor Commitment Letter to which it is a party solely has caused the termination giving rise to such obligation to pay the Parent Termination Fee and/or other losses or damages (“Parent Damages”), MD (in the event of such a breach by any MD Investor or MSDC Investor) or SLP III and SLP IV severally and not jointly (in the event of such a breach by any Equity Investor) (such Investors, as the case may be, the “Indemnifying Investor”) shall indemnify and hold harmless each other Investor that is not an Indemnifying Investor (such Investor or Investors, the “Indemnified Investors”) from and against all expenses, losses and damages incurred under the Limited Guarantees or other losses or damages and any out-of-pocket costs or expenses attributable to the Parent Termination Fee or such other losses or damages, whether pursuant to the Limited Guarantees or otherwise, including paying or reimbursing all of the Indemnified Investors’ Allocable Expenses pursuant to Section 2.8.2 (the “Indemnifiable Losses”), but Indemnifiable Losses shall not include lost profits, diminution in value or consequential, special or punitive damages except to the extent recovered by the Company or any third party and which constitute Parent Damages. If any of the MD Investors or MSDC Investor, on the one hand, and any of the Equity Investors, on the other hand, breached their respective express obligations under the Investor Commitment Letter to which it is a party and such breaches both have caused the termination giving rise to such obligation to pay Parent Damages, then MD and the Equity Investors shall each be Indemnifying Investors, and the obligations of MD, on the one hand, and the Equity Investors, on the other hand, shall be several and not joint, with each responsible for its pro rata share of the Indemnifiable Losses based on their respective Funding Percentage at such time (with MD’s Funding Percentage being deemed equal to the aggregate Funding Percentages of the MD Investors and MSDC Investor for this purpose). Notwithstanding anything herein to the contrary, it is understood and agreed that (a) if the Parent Termination Fee and/or other losses or damages are paid or are payable pursuant to the Merger Agreement solely because of the failure of the Debt Financing (as defined in the Merger Agreement) to be available on the date on which the Closing is required to occur pursuant to the Merger Agreement, or in the event the Cash Shortfall Fee is paid or payable, then MD, on the one hand, and the Equity Investors, on the other hand, shall each pay one half of the aggregate amount of such Parent Termination Fee, Cash Shortfall Fee and/or other losses or damages paid or payable pursuant to the Merger Agreement and (b) no Investor shall be obligated to pay an amount pursuant to its own Limited Guarantee and the terms of this Agreement that, in the aggregate, exceeds the aggregate Investor Commitment of such Investor as set forth on Exhibit C. For the avoidance of doubt, (1) Parent’s, Intermediate’s and/or Merger Sub’s breach of the Merger Agreement, or the failure of the Merger to be consummated, or the termination of the Merger Agreement, in each case, solely as

the result of the inability of any MD Investor to take an action under this Agreement or the MD Investors Commitment Letter, or to contribute the Rollover Shares or cash contribution to Parent pursuant to the terms and conditions of the MD Investors Commitment Letter, as a result of the death or disability of MD, shall be deemed to be a breach of the MD Investors’ express obligations under this Agreement and/or the MD Investors Commitment Letter, as the case may be, that solely has caused the obligation to pay Parent Damages such that the MD Investors shall be the “Indemnifying Investor” as contemplated in this Section 2.16 and (2) if Parent breaches Section 5.1(c) or the last sentence of Section 5.7(b) of the Merger Agreement as the result of an action or omission by either MD Investors or MSDC Investor, on the one hand, or the Equity Investors, on the other hand, MD (in the event of such a breach by any MD Investors or MSDC Investor) or SLP III and SLP IV, severally and not jointly (in the event of such a breach by any Equity Investors) shall be an “Indemnifying Investor” as contemplated in this Section 2.16.

2.17 Certain Tax Matters. Each of the Parties agrees that (i) the contribution by MD Investors of Rollover Shares and cash to Parent in exchange for shares of Parent common stock and (ii) the contribution by the Equity Investors and the MSDC Investor of cash to Parent in exchange for shares of Parent common stock, taken together (the “Contribution”), are intended to qualify as an exchange described in Section 351 of the Internal Revenue Code of 1986, as amended (the “Code”). Each of Parent and the Equity Investors agrees to deliver to counsel to MD a representation letter executed by Parent or the Equity Investor, as applicable, dated as of the Closing Date, substantially in the form of such party’s representation letter attached as Exhibit F hereto to support any opinion to be delivered to the MD Investors regarding the federal income tax treatment of the Contribution. In addition, each of the Investors agrees, without the prior written consent of MD, (i) not to take any action that could reasonably be expected to cause the Contribution to fail to qualify as an exchange described in Section 351 of the Code and (ii) in the event of a transfer by an Equity Investor of a portion of its equity commitment pursuant to a Sell-Down prior to the Closing, to require the applicable transferee, as a condition to such transfer, to covenant that such transferee will deliver to counsel to MD a representation letter executed by such transferee, dated as of the Closing Date, substantially in the form of the representation letter to be delivered to such counsel by the Equity Investor. Notwithstanding anything to the contrary herein or in any representation letter delivered by Parent pursuant to this Section 2.17, in no event shall Parent be liable to any party (including the MD Investors) for the failure of any representation, warranty or covenant contained in its representation letter to be true, correct or complete or for Parent’s failure to comply with any covenant contained in such representation letter.

2.18 Voting and Support Agreement. Each of the Investors acknowledges and agrees that, concurrently with execution of the Merger Agreement, and as a condition to the Company’s willingness to enter into the Merger Agreement, the MD Investors are executing a Voting and Support Agreement (the “Voting Agreement”) with the Company in the form set forth on Exhibit G. Notwithstanding any other provision of this Agreement, compliance by the MD Investors with the terms of the Voting Agreement shall not be deemed to violate this Agreement or any representation, warranty, covenant or other provision herein.

2.19.1 The Investors will as promptly as possible after the date of this Agreement cause the certificates of incorporation of Parent, Intermediate and Merger Sub to be amended to provide that any act by or on behalf of Parent, Intermediate or Merger Sub that has not been authorized in accordance with this Agreement or that otherwise violates or is inconsistent with this Agreement shall be null and void ab initio.

2.19.2 The Investors will cause the certificates of incorporation of Parent and those subsidiaries of Parent contemplated in the Stockholder Agreement Documents to be amended as soon as practicable following the Effective Time to conform to the terms set forth in Exhibit A.

2.20 Gift Trust Sale. On or prior to the Closing Date (but conditional upon the occurrence of the Closing), MD shall acquire from the Gift Trusts, and the Gift Trusts shall sell to MD, all of the shares of Company Common Stock held on the date hereof by the Gift Trusts.

3.1 Notices. All notices and other communications under this Agreement shall be in writing and shall be deemed given (a) when delivered personally by hand (with written confirmation of receipt), (b) when sent by facsimile (with written confirmation of transmission) or (c) one (1) Business Day following the day sent by an internationally recognized overnight courier (with written confirmation of receipt), in each case at the following addresses and facsimile numbers (or to such other address or facsimile number as a party may have specified by notice given to the other party pursuant to this provision):

3.2 Amendment. This Agreement may be amended or modified and the provisions hereof may be waived, only by an agreement in writing signed by the Requisite Investors.

3.3 Severability. In the event that any provision hereof would, under applicable Law, be invalid or unenforceable in any respect, such provision shall be construed by modifying or limiting it so as to be valid and enforceable to the maximum extent compatible with, and possible under, applicable Law. The provisions hereof are severable, and in the event any provision hereof should be held invalid or unenforceable in any respect, it shall not invalidate, render unenforceable or otherwise affect any other provision hereof.

3.4 Remedies. The parties hereto agree that, except as provided herein, this Agreement will be enforceable by all available remedies at law or in equity (including, without limitation, specific performance).

3.5 No Recourse. Notwithstanding anything that may be expressed or implied in this Agreement or any document or instrument delivered contemporaneously herewith, and notwithstanding the fact that the Equity Investors or the MSDC Investor may be a partnership or limited liability company, each of Parent and each Investor by its acceptance of the benefits of this Agreement, covenants, agrees and acknowledges that no Person other than the Equity Investors or the MSDC Investor shall have any obligation hereunder with respect to the obligations of the Equity Investors or the MSDC Investor, respectively, and no recourse under this Agreement or under any documents or instruments delivered in connection herewith or in respect of any oral representations made or alleged to be made in connection herewith or therewith shall be had against any former, current or future direct or indirect equityholders, controlling persons, stockholders, directors, officers, employees, Affiliates, members, managers, general or limited partners, agents, attorneys or other representatives of the Equity Investors or the MSDC Investor, or any of their successors or assigns, or any former, current or future direct or indirect equityholders, controlling persons, stockholders, directors, officers, employees, Affiliates, members, managers, general or limited partners, agents, attorneys or other representatives or successors or assignees of any of the foregoing (each, a “SLP Related Party” or an “MSDC Related Party”, respectively, and collectively, the “SLP Related Parties” or “MSDC Related Parties”, respectively), whether by the enforcement of any assessment or by any legal or equitable proceeding, or by virtue of any applicable law, it being agreed and acknowledged that no personal liability whatsoever shall attach to, be imposed on or otherwise be incurred by any SLP Related Party or MSDC Related Party for any obligations of any Equity Investor or the MSDC Investor, respectively, or any of its successors or permitted assigns under this Agreement or any documents or instrument delivered in connection herewith or in respect of any oral representations made or alleged to be made in connection herewith or therewith or for any claim (whether at law or equity, in tort, contract or otherwise) based on, in respect of, or by reason of such obligations or their creation.

3.6 No Third Party Beneficiaries. Except as provided in Section 3.12, this Agreement shall be binding on each party hereto solely for the benefit of each other party hereto and nothing set forth in this Agreement, express or implied, shall be construed to confer, directly or indirectly, upon or give to any Person other than the parties hereto any benefits, rights or remedies under or by reason of, or any rights to enforce or cause the parties hereto to enforce, any provisions of this Agreement; provided, however, that the SLP Related Parties and the MSDC Related Parties are express intended third party beneficiaries of Section 3.5.

3.7 Confidentiality. Each party hereto agrees to, and shall cause its Representatives to, keep any information supplied by or on behalf of any of the other parties to this Agreement, confidential (“Confidential Information”) and to use, and cause its Representatives to use, the Confidential Information only in connection with the Merger, the Transaction Agreements and the transactions contemplated hereby and thereby; provided, however, that the term “Confidential Information” does not include information that (a) is already in such party’s possession, provided that such information is not subject to another confidentiality agreement with or other obligation of secrecy to any person, (b) is or becomes generally available to the public other than as a result of a disclosure, directly or indirectly, by such party or such party’s Representatives, or (c) is or becomes available to such party on a non-confidential basis from a source other than any of the parties hereto or any of their respective Representatives (provided, that such source is not known by such party to be bound by a confidentiality agreement with or other obligation of secrecy to any person). Notwithstanding the foregoing, nothing herein shall prevent any party hereto from disclosing Confidential Information (i) upon the order of any court or administrative agency, (ii) upon the request or demand of any regulatory agency or authority having jurisdiction over such party, (iii) to the extent required by law or regulation, (iv) solely with respect to MD providing information regarding the Company, MD or his Affiliates to any person to the extent the Company is not prohibited from providing information regarding the Company and its Subsidiaries to such person under the Merger Agreement (but in no event shall MD be permitted to disclose any Confidential Information provided by, or regarding, any Equity Investor, its Affiliates and/or their respective Representatives, including their analysis of the Company and its Subsidiaries and structuring, and investment therein), (v) to the extent necessary in connection with the exercise of any remedy hereunder, (vi) in connection with a Sell-Down (including soliciting prospective investors) (subject to the prior execution by any recipient of Confidential Information of a confidentiality agreement reasonably acceptable to Parent), (vii) to such party’s Representatives and/or (viii) that is customarily provided to limited partners or investors or potential limited partners or investors in such party’s affiliated investment funds provided that such limited partners or investors or potential limited partners or investors are subject to a customary confidentiality obligation (it being understood and agreed that, in the case of clause (i), (ii) or (iii), such party shall notify the other parties hereto of the proposed disclosure as far in advance of such disclosure as practicable and request confidential treatment of any information so disclosed).

3.8 Press Release; Communications. The parties will coordinate any and all notices, releases, statements, communications to the general public or the press and any required filings, in each case, relating to this Agreement, the Merger Agreement, the Securities Purchase Agreement or the transactions contemplated hereby or thereby. Such releases, statements, communications and/or filings shall be made only at such times and in such manner as may be agreed upon by the Requisite Investors; provided, that any Investor shall be entitled to issue such press releases and to make such public statements as are required by applicable law, in which case any other Investor shall be advised thereof and such Investor together with the Requisite

Investors shall use their reasonable efforts to cause a mutually agreeable release or announcement to be issued; provided, further, that to the extent practicable, any required filing shall be approved by the Requisite Investors, with such approval not to be unreasonably withheld, conditioned or delayed prior to the public disclosure thereof.

3.9 Governing Law; Consent to Jurisdiction. 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, without giving effect to any choice or conflict of law provision or rule (whether of the State of Delaware or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the State of Delaware. In addition, each of the parties hereto irrevocably agrees that any legal action or proceeding with respect to this Agreement and the rights and obligations arising hereunder, or for recognition and enforcement of any judgment in respect of this Agreement and the rights and obligations arising hereunder brought by an party hereto or its successors or assigns, shall be brought and determined exclusively in the Delaware Court of Chancery, or, if the Delaware Court of Chancery declines to accept jurisdiction over a particular matter, any federal court within the State of Delaware, or, if both the Delaware Court of Chancery and the federal courts within the State of Delaware decline to accept jurisdiction over a particular matter, any other state court within the State of Delaware, and, in each case, any appellate court therefrom. Each of the parties hereto hereby irrevocably submits with regard to any such action or proceeding for itself and in respect of its property, generally and unconditionally, to the personal jurisdiction of the aforesaid courts and agrees that it will not bring any action relating to this Agreement or any of the transactions contemplated by this Agreement in any court other than the aforesaid courts. Each of the parties hereto hereby irrevocably waives, and agrees not to assert as a defense, counterclaim or otherwise, in any action or proceeding with respect to this Agreement, (i) any claim that it is not personally subject to the jurisdiction of the above named courts for any reason other than the failure to serve in accordance with this Section 3.9, (ii) any claim that it or its property is exempt or immune from the jurisdiction of any such court or from any legal process commenced in such courts (whether through service of notice, attachment prior to judgment, attachment in aid of execution of judgment, execution of judgment or otherwise) and (iii) to the fullest extent permitted by applicable Law, any claim that (x) the suit, action or proceeding in such court is brought in an inconvenient forum, (y) the venue of such suit, action or proceeding is improper or (z) this Agreement, or the subject matter hereof, may not be enforced in or by such courts. Each of the parties hereto agrees that service of process upon such party in any such action or proceeding shall be effective if such process is given as a notice in accordance with Section 3.1.

EACH OF THE PARTIES TO THIS AGREEMENT HEREBY IRREVOCABLY WAIVES TO THE EXTENT PERMITTED BY APPLICABLE LAW ANY AND ALL RIGHT TO A TRIAL BY JURY IN ANY DIRECT OR INDIRECT ACTION, PROCEEDING OR COUNTERCLAIM ARISING OUT OF OR RELATING TO THIS AGREEMENT, THE TRANSACTIONS CONTEMPLATED HEREIN.

3.11 Exercise of Rights and Remedies. No delay of or omission in the exercise of any right, power or remedy accruing to any party as a result of any breach or default by any other party under this Agreement shall impair any such right, power or remedy, nor shall it be construed as a waiver of or acquiescence in any such breach or default, or of any similar breach or default occurring later; nor shall any such delay, omission or waiver of any single breach or default be deemed a waiver of any other breach or default occurring before or after that waiver.

3.12 Other Agreements; Assignment. This Agreement, together with the Exhibits attached hereto and the agreements referenced herein, constitutes the entire agreement, and supersedes all prior agreements, understandings, negotiations and statements, both written and oral, among the parties or any of their Affiliates with respect to the subject matter contained herein except for the Merger Agreement, the Limited Guarantees, the Investor Commitment Letters and such other agreements as are referenced herein which shall continue in full force and effect in accordance with their terms. Other than as expressly provided herein, this Agreement may not be assigned (whether by operation of law or otherwise) without the prior written consent of the parties hereto. Any attempted assignment in derogation of the foregoing shall be null and void. This Agreement shall be binding on each Investor and its successors and permitted assigns (but in the case of the Gift Trusts, only with respect to the sections of this Agreement expressly binding thereon), and in the case of MD, his executors, administrators, personal representatives and heirs.

3.13 No Representations or Duty.

In making any determination contemplated by this Agreement, each Investor may make such determination in its sole and absolute discretion, taking into account only such Investor’s own views, self-interest, objectives and concerns. No Investor shall have any fiduciary or other duty to any other Investor or to Parent except as expressly set forth in this Agreement.

3.14 General. Nothing in this Agreement shall be deemed to constitute a partnership between any of the parties, nor shall any party constitute the partner or agent of any other party for any purpose.

3.15 Gift Trusts. The Gift Trusts shall be considered “Investors” for purposes of this Article III.

IN WITNESS WHEREOF, each of the undersigned has duly executed this Agreement (or caused this Agreement to be executed on its behalf by its officer or representative thereunto duly authorized) as of the date first above written.
