ARTICLE V

REPRESENTATIONS AND WARRANTIES OF MSI

MSI hereby represents and warrants to MHR as of the date of this Agreement and as of each Closing, as follows:

5.1                               Organization; Authority.  MSI is duly organized, validly existing and in good standing under the laws of the jurisdiction of its organization. MSI has the requisite power and authority to enter into any Transaction Documents to which MSI is a party and to consummate the Transactions hereunder and thereunder and otherwise to carry out its obligations hereunder and thereunder. There is no pending or, to the Knowledge of MSI, threatened Proceeding for the dissolution, liquidation or insolvency of MSI. MSI has taken all action necessary to authorize the execution, delivery and performance by MSI of the Transaction Documents and the consummation of the Transactions, including the purchase by MSI of the ArcLight Acquired Units pursuant to the ArcLight UPA and the MHR Acquired Units hereunder. Each of the Transaction Documents to which MSI is a party has been (or upon delivery will be) duly executed and delivered by MSI and constitutes, or when delivered in accordance with the terms hereof will constitute, the valid and binding obligation of MSI, enforceable against it in accordance with its terms, except as may be limited by (a) applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance or similar laws relating to or affecting the enforcement of creditors rights generally, (b) laws relating to the availability of specific performance, injunctive relief or by general principles of equity, or (c) to the extent indemnification provisions may be limited by applicable federal or state securities laws.

5.2                               No Violation.  The acquisition of the ArcLight Acquired Units and the MHR Acquired Units by MSI, and the execution, delivery and performance of this Agreement and the other Transaction Documents by MSI, and the consummation by MSI of the Transactions, including the purchase of the ArcLight Acquired Units pursuant to the ArcLight UPA and the MHR Acquired Units hereunder, assuming the accuracy of the representations and warranties of MHR and the Company contained herein and the performance of their respective covenants contained herein, (a) do not conflict with or result in any violation of or default under any provision of the certificate of formation, partnership agreement, limited liability company agreement or other organizational or charter documents of MSI, (b) do not conflict with or result in any violation of or default under, any provision of any material Contract, certificate or

36

instrument to which MSI is a party or by which MSI or any of its material assets are bound, (c) require any consent, approval, authorization, order, registration or qualification or filing with any Governmental Authority or other Person, or (d) violate any Law or other restriction of any Governmental Authority, except with respect to the foregoing clauses (b), (c) and (d), to the extent such conflict, default, violation or failure to obtain would not have a material adverse effect on any of MSI, the consummation of the Transactions or the performance or enforceability of any of the Transaction Documents.

5.3                               MSI Intent.  MSI is acquiring the ArcLight Acquired Units pursuant to the ArcLight UPA and the MHR Acquired Units hereunder for investment purposes only and not with a view to or for distributing or reselling such ArcLight Acquired Units or MHR Acquired Units or any part thereof, and MSI has no present intention of selling, granting any participation in, or otherwise distributing the same. MSI does not presently have any Contract with any Person to sell, transfer or grant participations to such Person or to any third Person, with respect to any ArcLight Acquired Units or MHR Acquired Units. Any sales or transfers of the ArcLight Acquired Units or MHR Acquired Units by MSI shall be in compliance with the Second A&R LLC Agreement and applicable state and federal laws.

5.4                               MSI Status.  MSI is an “accredited investor” (within the meaning of Rule 501 promulgated under the Securities Act) and has knowledge and experience in financial and business matters and in investments of this type that it is capable of evaluating the merits and risks of its investment in the Units and of making an informed decision. MSI is a United States person (as defined by Section 7701(a)(30) of the Code).

5.5                               Non-Reliance; Disclosure of Information.  MSI is not relying upon, and has not relied upon, any statement, representation or warranty made by any Person, except for the statements, representations and warranties by MHR and the Company contained in this Agreement. MSI acknowledges that any investment in the Company, including the purchase of the ArcLight Acquired Units and the MHR Acquired Units, is speculative and that the Business involves risk. The foregoing, however, does not limit or modify the representations and warranties of MHR and the Company in Article IV of this Agreement or the right of MSI to rely thereon.

5.6                               Restricted Securities.  MSI understands that the ArcLight Acquired Units and the MHR Acquired Units have not been, and will not be, registered under the Securities Act, by reason of a specific exemption from the registration provisions of the Securities Act which depends upon, among other things, the bona fide nature of the investment intent and the accuracy of MSI’s representations as expressed herein. MSI understands that the ArcLight Acquired Units and the MHR Acquired Units are “restricted securities” under applicable U.S. federal and state securities laws and that, pursuant to these laws, MSI must hold the ArcLight Acquired Units and the MHR Acquired Units indefinitely unless they are registered with the Commission and qualified by state authorities, or a valid exemption from such registration and qualification requirements is available. MSI acknowledges that the Company has no obligation to register or qualify the ArcLight Acquired Units or the MHR Acquired Units for resale, except as set forth in the Second A&R LLC Agreement. MSI understands that no public market now exists for the ArcLight Acquired Units or the MHR Acquired Units, and that the Company has made no

37

assurances that a public market will ever exist for the ArcLight Acquired Units or the MHR Acquired Units.

5.7                               Brokers’ Fees.  No brokerage or finder’s fees or commissions are or will be payable by MSI to any broker, financial advisor or consultant, finder, placement agent, investment banker, bank or other Person with respect to the Closing Transactions, and MSI has not taken any action that could cause MHR or any Eureka Party to be liable for any such fees or commissions.

5.8                               Original Unit Purchase Agreement.  To the knowledge of MSI (which means the actual knowledge of John Veech and Ahmad Atwan), the rights and obligations of MHR, the Company and ArcLight under the Original Unit Purchase Agreement have not been assigned to or assumed by any other Person.

ARTICLE VI

OTHER AGREEMENTS OF THE PARTIES

6.1                               Employee Matters.  MHR shall not, and shall cause its Affiliates not to, transfer or assign any Key Subject Employees to any other Person except in connection with the Employee Transfer (as defined in the Second A&R LLC Agreement) and, for one year after such Employee Transfer, MHR and its Subsidiaries shall not hire or seek to hire any of the Key Subject Employees without the prior written consent of MSI.

6.2                               Rogersville Facility.  At the request of MHR, Eureka Pipeline will assign to MHR or an Affiliate thereof (provided, that in respect of any assignment to such Affiliate, MHR shall contemporaneously therewith execute and deliver a parent guaranty in respect of such Affiliate’s assumption of any obligations arising from or relating to the Rogersville Facility as required by this Section 6.2, in form and substance reasonably satisfactory to MSI), all of Eureka Pipeline’s right, title and interest in and to the Rogersville Facility, pursuant to a form of deed or assignment and assumption agreement, acceptable to the Company and approved by MSI in writing (such approval not to be unreasonably withheld, conditioned or delayed) and by Eureka Pipeline’s lenders under the Credit Agreement. Any consent required by Eureka Pipeline’s lenders under the Credit Agreement or other existing credit facility or indentures to be executed and delivered by Eureka Pipeline (or any other Eureka Party) shall be in form and substance reasonably satisfactory to MSI. For the avoidance of doubt, such assignment and assumption agreement shall expressly disclaim any representations or warranties by Eureka Pipeline, and MHR shall assume all obligations or liabilities of the Company and its Subsidiaries related to the Rogersville Facility, whether arising in or relating to the past, present or future upon giving effect to such assignment. None of the Eureka Parties or their Affiliates shall incur any costs or expenses in connection with such assignment; any such costs or expenses shall be borne by MHR only, and MHR shall indemnify and hold harmless the Eureka Parties and their Affiliates for any such costs or expenses.

6.3                               Waiver of Claims.  Effective as of the Initial Closing, MHR hereby waives and releases any rights, remedies, causes of action, or any claims it has or may have, now or in the future, against any Eureka Party as a result of breaches of any agreements between MHR and its

Affiliates, on one hand, and any Eureka Party, on the other, occurring prior to the Initial Closing.  Effective as of the Initial Closing, MHR hereby releases each Eureka Party for any liabilities it may have as a result of such breaches.

6.4                               Conduct of the Business.  Except as required by applicable Law, from the date hereof until the Initial Closing, MHR and the Company shall cause the Eureka Parties to conduct the Business in the ordinary course in substantially the same manner as previously conducted and, to the extent consistent therewith, use reasonable efforts to keep intact its business, keep available the services of its current employees and preserve its relationships with customers, suppliers, licensors, licensees, distributors, lenders and others with whom it deals.  In addition (and without limiting the generality of the foregoing), except as expressly required by the terms of this Agreement or as required by applicable Law, from the date hereof until the Initial Closing, MHR shall not, and shall not permit any of the MHR Directors to, without the prior written consent of MSI, (a) vote in favor of or consent to any matter reserved to the Board or the holders of the Equity Interests of the Company in respect of which the Series A-2 Members and/or the Series A-2 Managers (as defined in the Second A&R LLC Agreement) would have had a consent or veto right under the Second A&R LLC Agreement had the Second A&R LLC Agreement been in effect at the time of such vote or consent, (b) cause or permit the Company to issue any Units of the Company or any other Equity Interests of any Eureka Party other than (i) Class A Common Units at a price equal to or greater than $[REDACTED]* per Class A Common Unit, (ii) Units of the Company that are, except as set forth in this clause (b)(ii), equivalent in all respects to Class A Common Units and issued at a price less than $[REDACTED]* per Unit, which Units (the “Special Units”) will, upon the occurrence of the Initial Closing and without the requirement of further action by the Company or any other Person, automatically convert into such number of Class A Common Units had the Special Units been issued at a price equal to $[REDACTED]* per Unit (e.g., if between the date hereof and the Initial Closing Date, the Company issues [REDACTED]* Special Units at a price equal to $[REDACTED]* per Special Unit, then such Special Units shall, upon the occurrence of the Initial Closing, automatically convert on the Initial Closing Date into [REDACTED]* Class A Common Units that were issued at a price equal to $[REDACTED]* per Class A Common Unit) and (iii) Class B Common Units, or (c) cause or permit the Company to make any distributions. For the avoidance of doubt, the parties recognize that the Series A-2 Members and the Series A-2 Managers have certain consent and veto rights from the Initial Closing until December 31, 2014, and certain consent and veto rights from and after January 1, 2015, and the restrictions set forth in this Section 6.4 shall be determined on the basis as of the applicable consent and veto rights arising under the Second A&R LLC Agreement as would be in effect on any given date of determination (provided that nothing herein shall be construed to affect, reduce or eliminate MSI’s consent rights in respect of the matters set forth in the immediately preceding sentence prior to the Initial Closing, which consent right shall apply as though the Second A&R LLC Agreement were in effect prior to the Initial Closing).

6.5                               Subject Acreage.  Effective as of the Initial Closing, MHR, on behalf of itself and its Affiliates, hereby grants to the Eureka Parties a right of first offer to provide midstream services with respect to the Subject Acreage, including gathering, processing, treating or compression services in respect of any Hydrocarbons produced from or by the Subject Acreage.

6.7                               Compliance Matters. The Company will (and MHR shall cause the Company to), upon the Initial Closing, adopt an anti-corruption compliance program substantially in form and substance reasonably satisfactory to MSI and MHR, together with any amendments agreed between MSI, MHR, and the Company from time to time.

The covenants made in this Agreement shall survive the Initial Closing and the Second Closing and remain operative and in full force and effect regardless of acceptance of any of the MHR Acquired Units and payment therefor and repayment, conversion, exercise or repurchase thereof. All indemnification obligations of MHR, the Company and MSI contained herein shall remain operative and in full force and effect unless such obligations are expressly terminated in a writing referencing that individual Section.

7.2                               Indemnification.

(a)                                 Subject to Sections 7.3 and 7.4 (including, for the avoidance of doubt, Section 7.4(b)), MHR and the Company shall, jointly and severally, indemnify and hold harmless MSI, the officers, directors, partners, members, agents, investment advisors and employees of MSI, each Person who controls MSI (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) and the officers, directors, partners, members, agents and employees of each such controlling Person (collectively, the “MSI Indemnified Parties”), to the fullest extent permitted by applicable law, from and against any and all Losses arising out of or relating to the breach of any of the representations, warranties or covenants of MHR or the Company contained herein, provided that such claim for indemnification relating to a breach of a representation or warranty is made prior to the expiration of the survival of such representation or warranty as set forth in Section 7.1.

41

(b)                                 Subject to Sections 7.3 and 7.4, MSI shall indemnify and hold harmless MHR and each Eureka Party, their respective directors, managers, partners, members, officers, agents, advisors and employees, each Person who controls MHR or any Eureka Party (within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act), and the directors, officers, partners, members, agents and employees of each such controlling Persons (collectively, the “Company Indemnified Parties”), to the fullest extent permitted by applicable law, from and against all Losses arising out of or relating to the breach of any of the representations, warranties or covenants of such MSI contained herein, provided that such claim for indemnification relating to a breach of a representation or warranty is made prior to the expiration of the survival of such representation or warranty as set forth in Section 7.1.

7.3                               Conduct of Indemnification Proceedings.

(a)                                 If any Proceeding shall be brought or asserted against any Person entitled to indemnity hereunder (an “Indemnified Party”), such Indemnified Party shall promptly notify the Person from whom indemnity is sought (the “Indemnifying Party”) in writing, and the Indemnifying Party shall assume the defense thereof, including the employment of one counsel reasonably satisfactory to the Indemnified Party and the payment of all fees and expenses incurred in connection with defense thereof; provided, that the failure of any Indemnified Party to give such notice shall not relieve the Indemnifying Party of its obligations or liabilities pursuant to this Agreement, except (and only) to the extent that it shall be finally determined by a court of competent jurisdiction (which determination is not subject to appeal or further review) that such failure shall have adversely prejudiced the Indemnifying Party.

(b)                                 An Indemnified Party shall have the right to employ separate counsel in any such Proceeding and to participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of such Indemnified Party or Parties unless: (i) the Indemnifying Party shall have failed promptly to assume the defense of such Proceeding; or (ii) the named parties to any such Proceeding (including any impleaded parties) include both such Indemnified Party and the Indemnifying Party. The Indemnifying Party shall not be liable for any settlement of any such Proceeding effected without its written consent, which consent shall not be unreasonably withheld.

(c)                                  All reasonable fees and expenses of the Indemnified Party that are Losses for which it has been agreed in good faith by the parties that the Indemnified Party is entitled to indemnification hereunder (including reasonable fees and expenses to the extent incurred in connection with investigating or preparing to defend such Proceeding in a manner not inconsistent with this Agreement) shall be paid to the Indemnified Party, as incurred, within ten Business Days of written notice thereof to the Indemnifying Party; provided, that the Indemnifying Party may require such Indemnified Party to undertake to reimburse all such fees and expenses to the extent it is judicially determined that such Indemnified Party is not entitled to indemnification for such fees and expenses hereunder.

*             THE REGISTRANT HAS REQUESTED AN ORDER FROM THE SECURITIES AND EXCHANGE COMMISSION (THE “SEC”) PURSUANT TO RULE 24B-2 OF THE SECURITIES EXCHANGE ACT OF 1934, AS AMENDED, GRANTING CONFIDENTIAL TREATMENT TO SELECTED PORTIONS OF THIS EXHIBIT.  ACCORDINGLY, THE CONFIDENTIAL PORTIONS HAVE BEEN OMITTED FROM THIS EXHIBIT AND HAVE BEEN FILED SEPARATELY WITH THE SEC.  OMITTED PORTIONS ARE INDICATED BY “[REDACTED]*”.

7.4                               Limitations.

(a)                                 No party shall be entitled to any recovery for any Losses for a breach of a representation or warranty unless and until the total of all Losses for the Company Indemnified Parties or MSI Indemnified Parties, as applicable, under Section 7.2 exceeds $1,000,000, at which time such parties shall be entitled to recover the aggregate amount of all Losses, regardless of such threshold; provided, however, that the aggregate liability for indemnity for breaches of representations or warranties under this Article VII for each of MHR and the Company collectively on the one hand, and MSI, on the other hand, shall not exceed an amount equal to [REDACTED]*. Notwithstanding anything in the foregoing to the contrary, the limitations contemplated by this Section 7.4 shall not apply to any claims for fraud or intentional, criminal or willful misrepresentation or misconduct. It is the intent of the parties that the indemnity provisions provided for in this Article VII shall be the sole and exclusive remedy of the parties under this Agreement, except as otherwise provided for in Section 9.12. In furtherance thereof, except as specifically provided in Section 9.12 and in the case of fraud or intentional, criminal or willful misrepresentation or misconduct, (i) the parties’ sole and exclusive remedy under this Agreement shall be to seek indemnification as set forth in this Article VII, and (ii) any claim for Losses against any party for any breach of this Agreement or in connection with any of the Transactions contemplated hereby will be made solely pursuant to this Article VII. Notwithstanding anything to the contrary set forth herein, if MSI actually recovers any amounts from ArcLight (net of any reasonable and documented out-of-pocket expenses incurred in connection therewith) for any matter in respect of which such amounts were paid pursuant to ArcLight’s indemnification obligations (if any) under the ArcLight UPA, then MHR and the Company shall be entitled to a credit in an amount equal to such amount in respect of such matter to the extent MHR and the Company are obligated to indemnify MSI hereunder with respect to such matter. MSI shall use its commercially reasonable efforts to seek indemnification in respect of any matter under which it is entitled to indemnification under both the ArcLight UPA and this Agreement first from ArcLight in respect of such matter, provided that MSI may, in its sole discretion, thereafter from time to time seek indemnification from MHR or the Company hereunder in respect of such matter.

(b)                                 The Company and MHR hereby acknowledges that one or more of the MSI Indemnified Parties (the “Institutional Investor Indemnitees”) have certain rights to indemnification, advancement of expenses or insurance provided by MSI or certain of MSI’s Affiliates (collectively, the “Institutional Investor Indemnitors”).  MHR and the Company hereby agree and acknowledge, that: (i) to the extent legally permitted and as required by the terms of this Agreement, (A) MHR is the indemnitor of first resort (i.e., its obligations to each Institutional Investor Indemnitee are primary and any obligation of the Institutional Investor Indemnitors to advance expenses or to provide indemnification for the same expenses or liabilities incurred by any Institutional Investor Indemnitee are secondary) and (B) MHR shall be required to advance the full amount of expenses incurred by an Institutional Investor Indemnitee and shall be liable for the full amount of all expenses, judgments, penalties, fines and amounts paid in settlement, in each case to the extent payable hereunder, without regard to any rights that an Institutional Investor Indemnitee may have against the Institutional Investor Indemnitors and

43

(ii) MHR irrevocably waives, relinquishes and releases the Institutional Investor Indemnitors from any and all claims for contribution, subrogation or any other recovery of any kind in respect of any of the matters described in clause (i) of this sentence for which any Institutional Investor Indemnitee has received indemnification or advancement from MHR. No MSI Indemnified Party shall be obligated to seek indemnification or advancement of expenses from the Company prior to seeking such indemnification or advancement of expenses from MHR, and MHR irrevocably waives, relinquishes and releases the Company from any and all claims for contribution, subrogation or any other recovery of any kind for which any MSI Indemnified Party has received indemnification or advancement from MHR. MHR and the Company further agree that no advancement or payment by the Institutional Investor Indemnitors on behalf of any Institutional Investor Indemnitee with respect to any claim for which an Institutional Investor Indemnitee has sought indemnification from MHR shall affect the foregoing and that the Institutional Investor Indemnitors shall have a right of contribution and/or be subrogated to the extent of such advancement or payment to all of the rights of recovery of such Institutional Investor Indemnitee against MHR.  Each party hereto agrees that the Institutional Investor Indemnitors are express third party beneficiaries of the terms of this Section 7.4(b).

(c)                                  Any use of “Material Adverse Effect” in any representation or warranty set forth in Article IV or any MHR Closing Certificate shall be disregarded for the purposes of this Article VII and any representations or warranties so qualified shall instead be deemed to be qualified with respect to accuracy, completeness, breach, significance, effect or damage (as applicable) by “material” or “materiality” (as applicable, and mutatis mutandis) in the determination of whether such representation or warranty has been breached and the amount of Losses caused by such breach; provided, however, that this provision shall not apply to the representation and warranty set forth in Section 4.15(a) and the related certification in any MHR Closing Certificate.

ARTICLE VIII

TERMINATION

8.1                               Termination. This Agreement shall survive in accordance with its terms, provided that this Agreement shall terminate automatically upon termination (if any) of the ArcLight UPA prior to the Initial Closing. If the Initial Closing does not occur on or before December 31, 2014, then either MHR or MSI shall be permitted, upon written notice to the other party, to terminate this Agreement for all purposes if such notice is given prior to the Initial Closing.

8.2                               Procedure and Effect of Termination.  If this Agreement is terminated pursuant to Section 8.1, all obligations of the parties under this Agreement will terminate for all purposes. Notwithstanding anything to the contrary set forth in any Transaction Document, in no event shall MSI or any of its Affiliates have any Liability whatsoever to MHR, the Company, their Affiliates or any other Person if the ArcLight Closing does not timely occur or otherwise does not occur for any reason (and without limiting the generality of the foregoing, MHR and the Company shall have no remedy of specific performance in respect of the transactions contemplated by the ArcLight UPA).

Any party may change any address or other contact information to which Notice is to be given to it by giving Notice as provided above of such change of address or other contact information.

9.3          Additional Information.  The Company may request from MSI such additional information as the Company may deem necessary to determine the eligibility of MSI to hold the Units or to enable the Company to determine the Company’s compliance with applicable regulatory requirements or tax status, and MSI shall provide such information as may reasonably be requested.

9.4          Amendments; Waivers.  No provision of this Agreement may be waived or amended except in a written instrument signed, in the case of an amendment, by MHR, the Company and MSI or, in the case of a waiver, by the party against whom enforcement of any such waiver is sought. No waiver of any default with respect to any provision, condition or requirement of this Agreement shall be deemed to be a continuing waiver in the future or a waiver of any subsequent default or a waiver of any other provision, condition or requirement hereof, nor shall any delay or omission of either party to exercise any right hereunder in any manner impair the exercise of any such right.

9.5          Construction.  The language used in this Agreement will be deemed to be the language chosen by the parties to express their mutual intent, and no rules of strict construction will be applied against any party. All references in this Agreement to Exhibits, Schedules, Articles, and Sections refer to the corresponding Exhibits, Schedules, Articles and Sections of or to this Agreement unless expressly provided otherwise. The headings herein are for convenience only, do not constitute a part of this Agreement and shall not be deemed to limit or affect any of the provisions hereof. The words “this Agreement,” “herein,” “hereby,” “hereunder” and “hereof” and words of similar import refer to this Agreement as a whole and not to any particular subdivision unless expressly so limited. The word “or” is not exclusive, and the word “including” (in its various forms) means “including, without limitation.” Pronouns in masculine, feminine or neuter genders shall be construed to state and include any other gender, and words, terms and titles (including terms defined herein) in the singular form shall be construed to include the plural and vice versa, unless the context otherwise requires.

9.6          Successors and Assigns.  This Agreement shall be binding upon and inure to the benefit of the parties and their successors and permitted assigns. None of the parties hereto may assign this Agreement or any rights or obligations hereunder without the prior written consent of the other parties, which consent shall not be unreasonably withheld. All or any portion of the Units acquired by MSI may be sold, assigned or pledged by MSI, subject to compliance with applicable securities laws, the terms of this Agreement and the terms of the Second A&R LLC Agreement.

9.7          No Third-Party Beneficiaries.  This Agreement is intended for the benefit of the parties hereto, the other Eureka Parties and all of such parties respective successors and permitted assigns and is not for the benefit of, nor may any provision hereof be enforced by, any other Person not expressly identified as an intended third-party beneficiary, except that each Indemnified Party is an intended third-party beneficiary of Section 7.2 and (in each case) may enforce the provisions of such Section directly against the parties with obligations thereunder.

9.8          Governing Law and Venue.  This Agreement, and any disputes, actions, claims or causes of action arising out of or in connection with this Agreement, shall be governed by the laws of the State of Delaware. Each party hereto submits to the exclusive jurisdiction of the federal courts located in Dallas, Texas (and the appellate courts thereto). This Agreement will not be governed by the United Nations Convention on Contracts for the International Sales of Goods, the application of which is expressly excluded. Each party agrees that it shall take no action to challenge the law and jurisdiction in this Section and shall use its best efforts to ensure that any such claim is adjudicated in such courts. Each party waives any defenses or objections to the agreed venue, jurisdiction or choice of law. Each party agrees that no treaty, law or rule or regulation of another country, whether local, federal or otherwise will pre-empt this Section. Each party understands and agrees that this jurisdiction requirement is a material condition of entering into this Agreement and agrees to indemnify and hold the other party harmless for any action or omission contrary to this material obligation. EACH OF THE PARTIES HERETO IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING BETWEEN THE PARTIES HERETO ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

47

9.9          Execution.  This Agreement may be executed in two or more counterparts, all of which when taken together shall be considered one and the same agreement and shall become effective when counterparts have been signed by each party and delivered to the other party, it being understood that the parties need not sign the same counterpart. In the event that any signature is delivered by facsimile or portable document format transmission, such signature shall create a valid and binding obligation of the party executing (or on whose behalf such signature is executed) with the same force and effect as if such signature page were an original thereof.

9.10        Severability.  If any provision of this Agreement is held to be invalid or unenforceable in any respect, the validity and enforceability of the remaining terms and provisions of this Agreement shall not in any way be affected or impaired thereby and the parties will attempt to agree upon a valid and enforceable provision that is a reasonable substitute therefor, and upon so agreeing, shall incorporate such substitute provision in this Agreement.

9.11        Fees and Expenses.  MHR shall bear its and the Eureka Parties’ costs and expenses arising out of the preparation, negotiation, execution and delivery of the Transaction Documents (including MHR and the Eureka Parties’ out of pocket costs arising out of their due diligence), and MSI shall bear its costs and expenses arising out of the preparation, negotiation, execution and delivery of the Transaction Documents (including MSI’s out of pocket costs arising out of its due diligence).

9.12        Remedies.  In addition to being entitled to exercise all rights to indemnification pursuant to Article VII and termination of this Agreement as provided herein, MSI, MHR and the Company will (but in all cases subject to Section 8.2) be entitled to seek specific performance under this Agreement in respect of the transactions relating to the Closing Transactions if the parties hereto are required by the terms hereof to consummate such transactions. The parties agree that monetary damages may not be adequate compensation for any Losses incurred by reason of any breach of obligations in this Agreement and hereby agree to waive in any action for specific performance of any such obligation the defense that a remedy at law would be adequate.

9.13        Updates to Disclosure Schedules.

(a)           (i) MHR shall have the right (but not the obligation) to deliver to MSI, from time to time after the execution of this Agreement or the Initial Closing Date, but no later than the second Business Day prior to either the Initial Closing Date or the Second Closing Date, as applicable, a schedule of changes to any of the Disclosure Schedules relating to any representations or warranties in Article IV with respect to matters arising after the execution of this Agreement or  the Initial Closing Date,  as the case may be,  that, if existing at the date of this Agreement, would have been required to be set forth or described in the Disclosure Schedules in order to make the applicable representations and warranties true and correct in all material respects as of the date hereof (each, an “Update Schedule”).  Such Update Schedule shall be deemed to be incorporated into and to supplement and amend the Disclosure Schedules (and all references to the “Disclosure Schedules” in this Agreement shall include such Update Schedule to the extent applicable).  To the extent that MHR determines that any such event, development or

48

occurrence on or after the execution of this Agreement or the Initial Closing Date (and any such determination prior to the Initial Closing Date shall be made in good faith by MHR), as applicable, that is the subject of the Update Schedule constitutes or relates to something that (either individually or in the aggregate with all or any other predecessor Update Schedule) would cause the representations and warranties contained in Article IV to not be true and correct in all material respects (other than representations and warranties that are qualified as to materiality or Material Adverse Effect, which event, development or occurrence would cause such representations and warranties to be not true and correct in all respects), then MHR will advise MSI in writing of such determination at the time that such Update Schedule is delivered to MSI (any Update Schedule in which MHR provides MSI written notice of such determination, a “Material Update”). Upon MSI’s receipt of any Material Update, MSI shall have the right to terminate Section 2.2 or Section 2.3 of this Agreement, as applicable, for all purposes without any liability whatsoever to MSI or MHR or their respective Affiliates.

(ii) Except as provided in Section 9.13(b), if MSI elects to proceed to the Initial Closing or the Second Closing notwithstanding the delivery of one or more Material Updates, MSI shall be deemed to have waived for all purposes of this Agreement all rights and remedies under this Agreement, the MHR Consent or applicable Law arising out of or related to the matters disclosed on such Update Schedule (including its right to not consummate the transactions contemplated hereby due to the failure of the condition set forth in Section 3.3(b)(i) and its right to seek indemnification hereunder) to the extent the items in the Update Schedule constitute a Material Update; provided, however, if the Initial Closing or the Second Closing, as applicable, occurs and no Material Updates have been delivered or if an Update Schedule has been provided that is not a Material Update, nothing in this Section 9.13 shall limit MSI’s right to indemnification pursuant to Article VII in respect of any event, development or occurrence that is the subject of any Update Schedule that constitutes a breach of any representation, warranty, covenant or agreement contained herein.

(b)           Notwithstanding anything to the contrary in Section 9.13(a):

(i) Any Material Update delivered after the Initial Closing shall in no event limit any of the MSI’s rights and remedies under this Agreement with respect to (or otherwise qualify or limit) any of MHR’s or the Company’s representations and warranties provided under (x) this Agreement prior to or as of the Initial Closing or (y) the MHR Closing Certificate delivered by MHR in connection with the Initial Closing.

(ii)  Any Material Update delivered before the Initial Closing with respect to the Specified Reps shall in no event limit any of MSI’s rights and remedies under this Agreement or otherwise qualify or limit any of MHR’s or the Company’s representations and warranties provided under this Agreement or any MHR Closing Certificate.

                (c)           The “Specified Reps” means Sections 4.1 (except to the extent any threatened Proceeding for the dissolution, liquidation or insolvency of MHR or any Eureka Party has been initiated by a third party), 4.2, 4.3, 4.4, 4.5, 4.6 (other than clause (a) of Section 4.6), 4.7, 4.8(a), 4.9, 4.10, 4.14, 4.15(f), 4.15(i), 4.15(l) (other than any

49

material Plans established or materially amended to the extent such Plans or amendments do not disproportionately favor or impact the Employees relative to the other employees of MHR and its Affiliates), 4.22(a), 4.22(d), 4.24 (but only as to the first two sentences of Section 4.24), 4.25 (other than clauses (a) and (d) of Section 4.25 and, other than the first sentence thereof, clause (g) of Section 4.25), 4.29, 4.31, 4.32, 4.33 and 4.35.

9.14        Confidentiality.  Each party hereto agrees that all confidential or proprietary information relating to the Transaction Documents or the transactions contemplated thereby (the “Confidential Information”) shall be kept confidential by such party and shall not be disclosed by such party in any manner whatsoever or used except in connection with the transactions contemplated by the Transaction Documents; provided, however, that any of such Confidential Information may be disclosed (i) to such party’s Affiliates, to Persons who are (or who are prospective) direct or indirect purchasers of membership interests of the Company and/or lenders to the parties hereto, their respective Affiliates and/or direct or indirect purchasers of membership interests of the Company and to managers, directors, officers, employees and authorized representatives (including attorneys, accountants, consultants, bankers and financial advisors) of each such party and of such party’s respective Affiliates (collectively, for purposes of this Section 9.14, “Representatives”), and each party hereto shall ensure its Representatives comply with the provisions of this Section 9.14 or substantially similar terms, and that such party shall be responsible for any noncompliance with this Section 9.14 by any of its Representatives as if such Representative was a party hereto; (ii) to the extent to which the Company (with Requisite Member Approval as if the Second A&R LLC Agreement were in effect at the time of such disclosure of such Confidential Information) consents in writing; (iii) to the extent not in violation of applicable Law or this Agreement, if disclosure is with respect to the terms of MSI’s investment in the Company pursuant to the Transaction Documents and the performance of that investment (whether in MSI’s or its Affiliates’ fundraising materials or otherwise); (iv) by a party hereto or any of its Representatives to the extent reasonably necessary in connection with such party’s enforcement of its rights under any Transaction Document; or (v) by any party hereto or its Affiliates or their respective Representatives to the extent that such Party or such Affiliate or any such Representative has received advice from its counsel that it is legally compelled to do so (including pursuant to the rules of an applicable stock exchange), provided, that, (A) MHR may describe the Transaction Documents and file the forms thereof in filings with the Securities and Exchange Commission or any stock exchange and may describe the Transaction Documents and the transactions contemplated thereby in any press release issued by MHR (provided that MHR shall provide MSI a reasonable opportunity to review and comment upon such filings or press releases in advance of making such filings or press releases (and to seek in good faith to incorporate such comments as are reasonably appropriate in respect of such filings, and not to make any press release (x) describing or referring to MSI or any of its Affiliates without the prior written consent of MSI or (y) describing the Transaction Documents or the transaction contemplated thereby without the prior written consent of MSI, which shall not be unreasonably conditioned, withheld or delayed, and MSI shall use its reasonable best efforts to promptly provide such consent following its receipt of the proposed final form of such press release; it being understood by the parties hereto that MSI and MHR are coordinating mutually agreeable forms of press releases to be released in connection with the Initial Closing, and MHR and MSI shall continue to coordinate in good faith in respect of such press releases) and shall seek confidential treatment of those commercially sensitive portions of the Transaction Documents in such filings upon the written request of MSI, assuming that there is a good faith

50

basis therefor) and (B) with respect to disclosures other than those described in clause (A), prior to making such disclosure, each party hereto or any of its Representatives, as the case may be, uses reasonable efforts to preserve the confidentiality of the Confidential Information, including consulting with the other parties hereto regarding such disclosure and, if reasonably requested by the such other parties, assisting such other parties, at such other parties’ respective expense, in seeking confidential treatment or a protective order to prevent the requested disclosure.
