Ladies and Gentlemen:

You have advised Credit Suisse AG (acting through such of its affiliates or branches as it deems appropriate, “CS”), Credit Suisse Loan Funding LLC (“CSLF” and, together with any designated affiliates and CS, “Credit Suisse”), Citigroup Global Markets Inc. (“CGMI”) on behalf of Citi (as defined below) and Jefferies Finance LLC (together with any of its designated affiliates, “Jefferies” and, together with Credit Suisse, Citi and any other Commitment Parties appointed as described below, collectively, the “Commitment Parties,” “we” or “us”) that:

(a) Prairie Private Acquiror LP, a Delaware limited partnership (the “Buyer” or “you”), formed at the direction of Blackstone Infrastructure Partners L.P. (together with its affiliates, collectively, “BIP”), Jasmine Ventures Pte. Ltd (together with its affiliates, collectively, “GIC”) and Enagas Holding USA, S.L.U. (together with its affiliates, collectively, “Enagas” and together with BIP and GIC, collectively the “Sponsors”) and certain other investors designated by the Sponsors (together with the Sponsors, the “Investors”), intends to merge (the “TGE Merger”) with and into Tallgrass Energy, LP, a Delaware limited partnership (“TGE” and, together with its subsidiaries, collectively, the “Acquired Business”), with TGE surviving the TGE Merger and the holders of Class A shares of TGE (other than the Sponsors) receiving cash in exchange for their Class A shares of TGE, such that following consummation of the TGE Merger and related transactions, the parent companies of the Buyer (prior to consummation of the TGE Merger) will own, directly or indirectly, approximately 55% of the economic interests (the “Subject Interests”) in Tallgrass Equity, LLC (“TE LLC”);

(b) it is intended that, substantially concurrent with the TGE Merger, Tallgrass Energy Partners, LP, a Delaware limited partnership (“TEP”), which is wholly-owned by TE LLC and its subsidiaries, will (i)(x) issue an aggregate principal amount of up to $575 million in senior unsecured notes (the “Senior Notes”) or other debt securities in lieu thereof (the “Securities”) in one or more Rule 144A offerings or other private placements on or prior to the Closing Date and/or (y) obtain a senior unsecured bridge facility providing an aggregate principal amount of up to $575 million of increasing rate bridge loans (the “Senior Bridge Facility”) on the Closing Date having the terms set forth in the Summary of Principal Terms and Conditions attached hereto as Exhibit B (the “Term Sheet”) and (ii) will use a portion of the proceeds of such Senior Notes, Securities and/or Senior Bridge Facility to make a distribution on the Closing Date (the “Closing Date Distribution”) through one or more of its parent companies to TGE to fund a portion of the Merger Consideration (as defined in the Acquisition Agreement);

(c) you wish for Credit Suisse, Citi and Jefferies to provide the Senior Bridge Facility pursuant to this commitment letter (together with the exhibits and other attachments hereto, this “Commitment Letter”); and

(d) you intend to consummate the other transactions described in Exhibit A hereto (the “Transaction Description”).

Capitalized terms used but not defined herein have the meanings assigned to them in the Exhibits attached hereto. For purposes of this Commitment Letter, “Citi” means CGMI, Citibank, N.A., Citicorp USA, Inc., Citicorp North America, Inc. and/or any of their affiliates as Citi shall determine to be appropriate to provide the services contemplated herein. It is understood and agreed that CGMI is entering into this Commitment Letter for and on behalf of Citi.

1. Commitments.

In connection with the Transactions, (a) CS is pleased to advise you of its commitment to provide 35% of the Senior Bridge Facility, (b) Citi is pleased to advise you of its commitment to provide 35% of the Senior Bridge Facility and (c) Jefferies is pleased to advise you of its commitment to provide 30% of the Senior Bridge Facility (CS, Citi and Jefferies, each in such capacity together with any of its designated affiliates of similar creditworthiness in such capacity, an “Initial Lender” and, collectively and with any other financial institution that becomes an Initial Lender as set forth in Section 2 below, the “Initial Lenders”), in each case, upon the terms and subject to the conditions set forth or referred to in this Commitment Letter and the Exhibits attached hereto.

2. Titles and Roles.

It is agreed that (a) CSLF, Citi and Jefferies will act as joint lead arrangers (each in such capacity, together with any of its designated affiliates of similar creditworthiness, a “Lead Arranger” and, together with any Additional Agents appointed in such capacity pursuant hereto, collectively, the “Lead Arrangers”) and as joint bookrunners for the Senior Bridge Facility and (b) CS will act as administrative agent (the “Administrative Agent”) for the Senior Bridge Facility. It is further agreed that CSLF will appear on the top left of the cover page of any marketing materials for the Senior Bridge Facility and that any Additional Agents will appear to the right of CSLF in such order as you and we shall mutually agree, in each case, holding the roles and responsibilities conventionally understood to be associated with such name placement. At any time on or prior to January 21, 2020, you may, in consultation with the Lead

2

Arrangers for the Senior Bridge Facility, appoint additional co-managers, agents, co-agents, arrangers, joint bookrunners or confer other titles in respect of the Senior Bridge Facility (each such party, an “Additional Agent”) (in addition to the Commitment Parties and any affiliates of the Sponsors (and any funds or partnerships managed or advised thereby) designated as an additional agent, co-agent, arranger, joint bookrunner or co-manager as described below) and may allocate up to 34% of the commitments of the Commitment Parties hereunder with respect to the Senior Bridge Facility (it being understood that such commitments shall be allocated ratably with respect to the Senior Bridge Facility) (and thereafter, such financial institution shall constitute a “Commitment Party” and an “Initial Lender” hereunder) and corresponding compensatory economics in connection with the Senior Bridge Facility to such Additional Agents. Notwithstanding anything in Section 3 to the contrary, the commitments of, and economics allocated to, the Initial Lenders with respect to the Senior Bridge Facility will be permanently reduced by the amount of the commitments of, and economics allocated to, such Additional Agents (or their affiliates) in respect of the Senior Bridge Facility, with such reduction allocated to reduce the commitments of, and economics allocated to, the Initial Lenders in respect of the Senior Bridge Facility (excluding any Initial Lender that becomes a party hereto pursuant to this section) on a pro rata basis; provided that in no event shall the economics payable to any Additional Agent exceed the fees (exclusive of any fees payable to the Administrative Agent in its capacity as such) which are being paid to the Initial Lenders (as a percentage of their commitments) pursuant to the Fee Letter. Notwithstanding the foregoing, following such appointments and prior to the date of the bank meeting in connection with the Senior Bridge Facility, you may make appointments of titles in respect of and/or allocations of the Senior Bridge Facility to affiliates of the Sponsors (and any funds or partnerships managed or advised thereby) with respect to an amount up to the difference between (a) the aggregate amount of the commitments of the Commitment Parties previously allocated to the Additional Agents hereunder and (b) the maximum aggregate amount of the commitments of the Commitment Parties permitted to be allocated to the Additional Agents hereunder; provided that any such appointments of and/or allocations to affiliates of the Sponsors will permanently reduce the amount of the commitments and corresponding compensatory economics that were previously allocated to each of the Initial Lenders and the Additional Agents with respect to the Senior Bridge Facility, with such reduction allocated to reduce the commitments of, and economics allocated to, the Initial Lenders and the Additional Agents in respect of the Senior Bridge Facility on a pro rata basis. No compensation (other than that expressly contemplated by this Commitment Letter and the Fee Letter referred to below) will be paid or titles awarded (other than as set forth above), in each case, in connection with the Senior Bridge Facility unless you and the Commitment Parties shall so agree.

3. Syndication.

The Commitment Parties reserve the right, prior to or after the execution of the Senior Bridge Facility Documentation, to syndicate all or a portion of the Commitment Parties’ commitments hereunder to a group of banks, financial institutions and other institutional lenders identified by the Commitment Parties in consultation with you and reasonably acceptable to you (with such acceptance not to be unreasonably withheld, conditioned or delayed), including any relationship lenders designated by you in consultation with the Commitment Parties (together with the Initial Lenders, the “Senior Bridge Facility Lenders”); provided that, except as expressly set forth in Section 2 above, notwithstanding the Commitment Parties’ right to syndicate the Senior Bridge Facility and receive commitments with respect thereto, the Commitment Parties may not assign all or any portion of their commitments hereunder until after the Closing Date, and, unless you agree in writing, the Commitment Parties shall retain exclusive control over all rights and obligations with respect to their commitments, including all rights with respect to consents, modifications, waivers and amendments, until the Closing Date has occurred; provided, further, that except as expressly set forth in Section 2 above, such syndication shall not relieve any Initial Lender of its obligations set forth herein (including its obligations to fund the Senior Bridge Facility on the Closing Date on the terms and conditions set forth in this Commitment Letter). Notwithstanding the foregoing, the Commitment Parties will not syndicate to those banks, financial institutions and other institutional lenders

3

and competitors of the Acquired Business separately identified in writing by you or any of the Sponsors to us prior to the date hereof or with respect to competitors (and such competitors’ sponsors and affiliates identified in writing or clearly identifiable solely on the basis of their names) of the Acquired Business, separately identified in writing by you or any of the Sponsors to us after the date hereof and prior to syndication of the Senior Bridge Facility (the foregoing, in each case inclusive of any affiliates thereof that are clearly identifiable by name (other than a bona-fide debt fund), collectively, “Disqualified Lenders”). After the Closing Date, the list of Disqualified Lenders may be updated from time to time to include competitors (and such competitors’ sponsors and affiliates (in each case, other than bona-fide debt funds) identified in writing or clearly identifiable solely on the basis of their names) of the Acquired Business separately identified in writing to the Administrative Agent, it being understood that any such update to the list of Disqualified Lenders will not apply retroactively to disqualify any person that has previously acquired an assignment or participation interest in the Senior Bridge Facility. Without limiting your obligations to assist with syndication efforts as set forth below, it is understood that the Initial Lenders’ commitments hereunder are not subject to commencement or completion of syndication of the Senior Bridge Facility or your satisfaction of such obligations.

The Commitment Parties intend to commence syndication efforts promptly after your acceptance of this Commitment Letter and as part of its syndication efforts, it is the Commitment Parties’ intent to have Senior Bridge Facility Lenders commit to the Senior Bridge Facility prior to the Closing Date. You agree to use your commercially reasonable efforts to assist the Commitment Parties in completing a timely syndication of the Senior Bridge Facility that is reasonably satisfactory to us and you until the date that is the earlier of (a) 60 days after the Closing Date and (b) the later of the Closing Date and the date on which each Initial Lender holds none of the Senior Bridge Facility (such earlier date, the “Syndication Date”). Such assistance shall include without limitation (a) your using commercially reasonable efforts to ensure that any syndication efforts benefit materially from your existing lending and investment banking relationships and the existing lending and investment banking relationships of the Sponsors, (b) your facilitating direct contact between your senior management, representatives and advisors (and your using commercially reasonable efforts to arrange for direct contact between senior management, representatives and advisors of the Sponsors and, to the extent practical and appropriate and consistent with the Acquisition Agreement, the Acquired Business) and the proposed Senior Bridge Facility Lenders at times and locations as mutually agreed upon reasonable prior notice, (c) your assistance (and your using commercially reasonable efforts to cause the Sponsors and, to the extent practical and appropriate and consistent with the Acquisition Agreement, the Acquired Business to assist) in the preparation of a customary confidential information memorandum (“Confidential Information Memorandum”) for the Senior Bridge Facility (which shall be in form and substance consistent with confidential information memoranda in recent transactions sponsored by BIP) and other customary marketing materials to be used in connection with the syndications, (d) using your commercially reasonable efforts to procure prior to the launch of syndication of the Senior Bridge Facility public corporate ratings (but no specific rating) for the Senior Bridge Facility Borrower and public ratings (but no specific rating) for the Senior Bridge Facility and the Senior Notes from each of Standard & Poor’s Ratings Services and Moody’s Investors Service, Inc. and (e) the hosting, with the Commitment Parties, of one or more meetings (or, if agreed to by the Lead Arrangers, conference calls in lieu thereof) with prospective Senior Bridge Facility Lenders at times and, if applicable, locations to be mutually agreed upon. Notwithstanding anything set forth herein, you shall only be required to use commercially reasonable efforts to cause the Acquired Business to assist with the syndication efforts in respect thereof and only to the extent such assistance is consistent with the Acquisition Agreement.

During the primary syndication of the Senior Bridge Facility and on or prior to the Syndication Date, you agree to use your commercially reasonable efforts to prepare and provide (and to use commercially reasonable efforts to cause the Sponsors and, to the extent consistent with the Acquisition Agreement, the Acquired Business to provide) promptly to the Commitment Parties all available customary information with respect to you, the Acquired Business and each of your and their respective subsidiaries, the Transactions and the other transactions contemplated hereby, including all financial information and projections relating to you and the Acquired Business (including financial estimates, forecasts and other forward-looking information) (the “Projections”), as the Commitment Parties may reasonably request.

4

For the avoidance of doubt, you will not be required to provide any information to the extent the provision thereof would violate any applicable law, rule or regulation or any obligation of confidentiality binding on you, any of the Sponsors, the Acquired Business or your or their respective affiliates (provided that in the case of any confidentiality obligation, (a) you shall have used commercially reasonable efforts to obtain consent to provide such information and (b) such obligation was not entered into in contemplation of this provision; provided, further, that you shall notify us if any such information is being withheld as a result of any such applicable law, rule, regulation or obligation of confidentiality). Notwithstanding anything to the contrary contained in this Commitment Letter or the Fee Letter, no provision of this paragraph shall constitute a condition to the commitments hereunder or the funding of the Senior Bridge Facility on the Closing Date or any time thereafter and neither the commencement nor the completion of the syndication of the Senior Bridge Facility shall constitute a condition precedent to the Closing Date.

During the primary syndication of the Senior Bridge Facility and until the Syndication Date, you will use commercially reasonable efforts to ensure (and use commercially reasonable efforts to cause the Sponsors to ensure) that there will not be any competing issues of debt securities or syndicated credit facilities by any Senior Bridge Facility Credit Party, in each case, without our consent (not to be unreasonably withheld, conditioned or delayed) (other than the Senior Bridge Facility, the Senior Notes, any Securities, any short term working capital facilities and capital lease, purchase money, equipment financings and any ordinary course refinancing of any indebtedness of TEP or any of its restricted subsidiaries existing on the date hereof (including the TEP Revolver, collectively, the “TEP Closing Date Debt Facilities”) (other than of the 2023 Notes, the 2024 Notes (as defined in the Fee Letter) or TEP’s “2028 notes”, which shall not be permitted without our consent (not to be unreasonably withheld, conditioned or delayed) if the refinancing thereof could reasonably be expected to materially impair the primary syndication of the Senior Bridge Facility), all other indebtedness permitted (other than indebtedness that is permitted solely with the Buyer’s consent) under the Acquisition Agreement and indebtedness under the TEP Revolver) (and any permitted refinancing thereof) (and, for the avoidance of doubt, any amendment or modification to any TEP Closing Date Debt Facility that does not involve the incurrence of additional indebtedness)) being offered, placed or arranged that could reasonably be expected to materially impair the primary syndication of the Senior Bridge Facility.

The Commitment Parties will, in consultation with you, manage all aspects of any syndication, including decisions as to the selection of institutions to be approached (with your consent not to be unreasonably withheld, conditioned or delayed and excluding Disqualified Lenders) and when they will be approached, when their commitments will be accepted, which institutions will participate (with your consent not to be unreasonably withheld, conditioned or delayed and excluding Disqualified Lenders), the allocation of the commitments among the Senior Bridge Facility Lenders and the amount and distribution of fees among the Senior Bridge Facility Lenders.

Notwithstanding anything to the contrary contained in this Commitment Letter (including each of the exhibits attached hereto), the Fee Letter, the Senior Bridge Facility Documentation or any other letter agreement or other undertaking concerning the financing of the Transactions (a) none of the obligations described in this Section 3 or Section 4 below (including, without limitation, the compliance with any of the provisions set forth above) shall constitute a condition to the commitments hereunder or the funding of the Senior Bridge Facility on the Closing Date or any time thereafter, (b) neither the commencement nor the completion of the syndication of the Senior Bridge Facility nor your satisfaction of your obligations to assist with syndication efforts as set forth in this Section 3 shall constitute a condition to the funding of the Senior Bridge Facility on the Closing Date or any time thereafter and (c) the only financial statements that shall be required to be provided to the Lead Arrangers or Initial Lenders in connection with the syndication of the Senior Bridge Facility or otherwise shall be those required to be delivered pursuant to paragraphs 8 and 9 of the Funding Conditions.

4. Information.

You hereby represent and warrant (with respect to the Acquired Business, to your knowledge) that (but the accuracy of which representation and warranty shall not be a condition to the commitments hereunder or the funding of the Senior Bridge Facility on the Closing Date) (a) all written information and written data (such information and data, other than (i) the Projections and (ii) information of a general economic or general industry nature, the “Information”) that have been or will be made available to the Commitment Parties by you, the Sponsors or any of your or their respective representatives, taken as a whole, is or will be, when furnished, correct in all material respects and does not or will not, when furnished, contain any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements contained therein not materially misleading in light of the circumstances under which such statements are made (after giving effect to all supplements and updates thereto that have been provided to us) and (b) the Projections that have been or will be made available to the Commitment Parties by you or by the Sponsors or any of your or their respective representatives have been or will be prepared in good faith based upon assumptions that are believed by you to be reasonable at the time made and furnished; it being understood that any such financial projections are subject to significant uncertainties and contingencies, many of which are beyond your control, that no assurance can be given that any particular financial projections will be realized, that actual results may differ significantly from the projected results and that such differences may be material. You agree that, if at any time prior to the Syndication Date, you become aware that any of the representations in the preceding sentence would be incorrect in any material respect if the Information and Projections were being furnished, and such representations were being made, at such time, then you will promptly use commercially reasonable efforts to supplement the Information and the Projections so that such representations will be correct in all material respects (with respect to the Acquired Business, to your knowledge) under those circumstances. In arranging and syndicating the Senior Bridge Facility, the Lead Arrangers will be entitled to use and rely on the Information and the Projections without responsibility for independent verification thereof. We will have no obligation to conduct any independent evaluation or appraisal of the assets or liabilities of you, the Acquired Business or any other party or to advise or opine on any related solvency issues.

You hereby acknowledge that (a) the Lead Arrangers will make available Information, Projections and other offering and marketing material and presentations, including confidential information memoranda to be used in connection with the syndication of the Senior Bridge Facility to the proposed syndicate of Senior Bridge Facility Lenders, by posting the Information and Projections on Debtdomain (the “Platform”) and (b) certain of the Senior Bridge Facility Lenders may be “public side” lenders (i.e., Senior Bridge Facility Lenders that do not wish to receive material non-public information with respect to you, the Acquired Business, your or its respective subsidiaries or the respective securities of any of the foregoing) (each, a “Public Lender”). At the reasonable request of the Lead Arranger, you agree to assist us in preparing an additional version of the Confidential Information Memorandum to be used by Public Lenders. The information to be included in the additional version of the Confidential Information Memorandum will consist exclusively of information and documentation that is either publicly available, not material with respect to you and your subsidiaries, the Acquired Business, their subsidiaries, or your and their respective securities for purposes of United States federal and state securities laws or of the type that would be publicly available if you, your subsidiaries, the Acquired Business or any of its respective subsidiaries, were a public reporting company (as reasonably determined by you). It is understood that in connection with your assistance described above, (a) a customary authorization letter executed by you will be included in each such Confidential Information Memorandum that authorizes the distribution of such Confidential Information Memorandum to prospective Senior Bridge Facility Lenders, contains customary representations confirming that the public side version does not include material non-public information

6

about you, the Acquired Business, your or their respective subsidiaries or your and their respective securities, and exculpate us, you, the Sponsors, the Acquired Business and our, your and their respective affiliates with respect to any liability related to the use or misuse of the contents of such Confidential Information Memorandum or any related marketing material by recipients thereof; (b) the public lender information shall include the following information except to the extent you notify us to the contrary, provided that you shall have been given a reasonable opportunity to review such documents and comply with the U.S. Securities and Exchange Commission disclosure requirements (and such public information is permitted to be made available to all prospective Senior Bridge Facility Lenders, including through a Platform designated “Public Lenders”): (i) drafts and final definitive documentation with respect to the Senior Bridge Facility, including term sheets, (ii) administrative materials prepared by the Commitment Parties for prospective Senior Bridge Facility Lenders (such as a lender meeting or call invitation, allocations and funding and closing memoranda) and (iii) notification of changes in the terms of the Senior Bridge Facility; (c) at our reasonable request, you shall identify information to be distributed to Public Lenders by clearly and conspicuously marking the same as “PUBLIC”, it being understood that you shall not otherwise be under any obligation to mark Information as “PUBLIC”; and (d) we shall be entitled to treat any Information and Projections that are not specifically identified as “PUBLIC” as being suitable only for posting on a portion of the Platform not designated for Public Lenders.

5. Fees.

As consideration for the commitment of the Initial Lenders hereunder and the Lead Arrangers’ agreement to perform the services described herein, you agree to pay the fees set forth in the Fee Letter dated the date hereof and delivered herewith with respect to the Senior Bridge Facility (as amended, amended and restated, supplemented or otherwise modified from time to time, the “Fee Letter”). Once paid, such fees shall not be refundable under any circumstances, except as otherwise contemplated by the Fee Letter.

6. Conditions Precedent.

The commitments of the Initial Lenders hereunder are subject only to the conditions expressly set forth in Exhibit C hereto (the “Funding Conditions”); it being understood that there are no conditions (implied or otherwise) to the commitments hereunder for the Senior Bridge Facility (including compliance with the terms of this Commitment Letter, the Fee Letter and the Senior Bridge Facility Documentation) other than the Funding Conditions (and upon satisfaction or waiver of the Funding Conditions, the funding under the Senior Bridge Facility shall occur).

Notwithstanding anything to the contrary in this Commitment Letter (including each of the exhibits attached hereto), the Fee Letter, the Senior Bridge Facility Documentation or any other letter agreement or other undertaking concerning the financing of the Transactions, (a) the only representations and warranties the accuracy of which shall be a condition to availability of the Senior Bridge Facility to be funded on the Closing Date shall be (i) such of the representations and warranties made by the Acquired Business in the Acquisition Agreement as are material to the interests of the Senior Bridge Facility Lenders, but only to the extent that you (or your applicable affiliates) have the right (taking into account any applicable cure provisions) to terminate your (or such affiliates’) obligations under the Acquisition Agreement to consummate the TGE Merger, or to decline to consummate the TGE Merger (in accordance with the terms thereof), as a result of a breach of such representations and warranties (to such extent, the “Acquisition Agreement Representations”) and (ii) the Specified Representations made by the Senior Bridge Facility Credit Parties in the Senior Bridge Facility Documentation and (b) the terms of the Senior Bridge Facility Documentation and the Closing Deliverables shall be in a form such that they do not impair the availability of the Senior Bridge Facility to be funded on the Closing Date if the Funding Conditions are satisfied (or waived). For purposes hereof, “Specified Representations” means the representations and warranties of

7

the Senior Bridge Facility Credit Parties set forth in the Senior Bridge Facility Documentation relating to corporate or other organizational existence, organizational power and authority (as to execution, delivery and performance of the Senior Bridge Facility Documentation), the due authorization, execution and delivery of the Senior Bridge Facility Documentation (in each case, by or of each Senior Bridge Facility Credit Party), enforceability of the Senior Bridge Facility Documentation against the Senior Bridge Facility Credit Parties, Federal Reserve margin regulations, the Investment Company Act, no conflicts of the Senior Bridge Facility Documentation (limited to the execution, delivery and performance of the Senior Bridge Facility Documentation, incurrence of indebtedness thereunder and the granting of the guarantees in respect thereof) with charter documents of such Senior Bridge Facility Credit Party, solvency as of the Closing Date of the Senior Bridge Facility Borrower and its subsidiaries on a consolidated basis (after giving effect to the Transactions) (to be determined in a manner consistent with the solvency certificate to be delivered in the form set forth in Annex I attached to Exhibit C hereto), Patriot Act and use of the proceeds of the Senior Bridge Facility not violating OFAC or FCPA. This paragraph shall be referred to herein as the “Limited Conditionality Provision”.

7. Indemnification; Expenses.

You agree (a) to indemnify and hold harmless each Commitment Party and each of its affiliates and controlling persons and the respective officers, directors, employees, successors, partners, agents, advisors and representatives of each of the foregoing (each, an “Indemnified Person”) from and against any and all actions, suits, investigations, inquiries, proceedings, losses, claims, damages, liabilities and out-of-pocket expenses, joint or several, to which any such Indemnified Person may become subject arising out of, resulting from or in connection with this Commitment Letter, the Fee Letter, the Transactions or the Senior Bridge Facility, the use or intended use of the proceeds of the Senior Bridge Facility, or any claim, litigation, investigation or proceeding (any of the foregoing, an “Action”) relating to any of the foregoing and regardless of whether brought by you or any of your affiliates or any other person or against any person, including the Acquired Business, its respective security holders and their respective other affiliates, regardless of whether any such Indemnified Person is a party thereto, and to reimburse each such Indemnified Person within 30 days after receipt of a written request together with reasonably detailed backup documentation for any reasonable legal expenses (limited to one counsel for all Indemnified Persons, taken as a whole, and, if reasonably necessary, a single local counsel to all Indemnified Persons, taken as a whole, in each relevant material jurisdiction and, solely in the case of an actual or perceived conflict of interest, one additional counsel in each applicable material jurisdiction to the affected Indemnified Persons similarly situated taken as a whole) or other reasonable and documented out-of-pocket expenses incurred in connection with investigating or defending any of the foregoing; provided that the foregoing indemnity will not, as to any Indemnified Person, apply to losses, claims, damages, liabilities or related expenses (i) to the extent resulting from the willful misconduct, bad faith or gross negligence of such Indemnified Person or any of its affiliates or controlling persons or any of the officers, directors, employees, partners, successors, agents, advisors or representatives of any of the foregoing, (ii) to the extent arising from a material breach of the obligations of such Indemnified Person or any of its affiliates or controlling persons or any of the officers, directors, employees, partners, successors, agents, advisors or representatives of any of the foregoing under this Commitment Letter, the Fee Letter or the Senior Bridge Facility Documentation (in the case of each of preceding clauses (i) and (ii), as determined by a court of competent jurisdiction in a final and non-appealable judgment) or (iii) to the extent arising from any dispute solely among Indemnified Persons other than claims against the Commitment Party in its capacity or in fulfilling its role as an Administrative Agent or arranger or any similar role under the Senior Bridge Facility and other than any claims arising out of any act or omission on the part of you or your affiliates, and (b) to reimburse each Commitment Party and each Indemnified Person from time to time, upon presentation of a summary statement, together with any supporting documentation reasonably requested by you, for all reasonable and documented out-of-pocket expenses (including but not limited to out-of-pocket expenses of such Commitment Party’s due diligence investigation, syndication expenses, travel expenses and

8

reasonable fees, disbursements and other charges of counsel to such Commitment Party identified in the Term Sheet, and, if necessary, of a single local counsel to such Commitment Party in each relevant material jurisdiction), in each case incurred in connection with the Senior Bridge Facility and the preparation of this Commitment Letter, the Fee Letter and the Senior Bridge Facility Documentation (collectively, the “Expenses”); provided that you shall not be required to reimburse any of the Expenses in the event the Closing Date does not occur. Notwithstanding any other provision of this Commitment Letter, (a) no Indemnified Person shall be liable for any damages arising from the use or misuse by others of information or other materials obtained through electronic, telecommunications or other information transmission systems, except to the extent such damages have resulted from (in each case as finally determined by a court of competent jurisdiction in a final and non-appealable judgment) the willful misconduct, bad faith or gross negligence of such Indemnified Person or any of its affiliates or controlling persons or any of the officers, directors, employees, partners, agents, advisors or representatives of any of the foregoing and (b) neither (i) any Indemnified Person, nor (ii) you, the Investors (nor any of your or their respective subsidiaries or affiliates) or the Acquired Business (or any of their respective subsidiaries or affiliates) shall be liable for any indirect, special, punitive or consequential damages (in the case of clause (ii), other than in respect of any such damages required to be indemnified under this Section 7) in connection with this Commitment Letter, the Senior Bridge Facility, the Transactions (including the Senior Bridge Facility and the use of proceeds thereunder), or with respect to any activities related to the Senior Bridge Facility. You shall not be liable for any settlement, compromise or consent to the entry of any judgment in any Action effected without your prior written consent (which consent shall not be unreasonably withheld, conditioned or delayed), but if settled with your written consent or if there is a final judgment in any such Action, you agree to indemnify and hold harmless each Indemnified Person from and against any and all losses, claims, damages, liabilities and expenses by reason of such settlement or judgment in accordance with, and to the extent required by, this Section 7. You shall not, without the prior written consent of the affected Indemnified Person (which consent shall not be unreasonably withheld, delayed or conditioned), effect any settlement of any pending or threatened Action against such Indemnified Person in respect of which indemnity has been sought hereunder by such Indemnified Person unless such settlement (a) includes an unconditional release of such Indemnified Person in form and substance reasonably satisfactory to such Indemnified Person (which approval shall not be unreasonably withheld, delayed or conditioned) from all liability or claims that are the subject matter of such Action and (b) does not include any statement as to any admission of fault. Notwithstanding the foregoing, each Indemnified Person shall be obligated to refund and return promptly any and all amounts paid by you or any of your affiliates under this Section 7 to such Indemnified Persons for any loss, claim, expense, damage or liability with respect to which such Indemnified Person was not entitled to payment in accordance with the terms hereof.

8. Sharing Information; Absence of Fiduciary Relationship; Affiliate Activities.

You acknowledge that each Commitment Party and its affiliates may be providing debt financing, equity capital or other services (including, without limitation, investment banking and financial advisory services, securities trading, hedging, financing and brokerage activities and financial planning and benefits counseling) to other companies in respect of which you may have conflicting interests. We will not furnish confidential information obtained from you by virtue of the transactions contemplated by this Commitment Letter or our other relationships with you to other companies (except as contemplated in Section 12 below). You also acknowledge that we do not have any obligation to use in connection with the transactions contemplated by this Commitment Letter, or to furnish to you, confidential information obtained by us or any of our respective affiliates from other companies.

You further acknowledge and agree that (a) no fiduciary, advisory or agency relationship between you and any Commitment Party is intended to be or has been created in respect of any of the transactions contemplated by this Commitment Letter, irrespective of whether such Commitment Party has advised or is advising you on other matters, (b) each Commitment Party, on the one hand, and you, on the other hand,

9

have an arm’s-length business relationship that does not directly or indirectly give rise to, nor do you rely on, any fiduciary duty on the part of such Commitment Party and you waive, to the fullest extent permitted by law, and agree not to assert any claims you may have against us for breach of fiduciary duty or alleged breach of fiduciary duty in connection with the Transactions and agree that we will have no liability (whether direct or indirect) to you in respect of such a fiduciary duty claim or to any person asserting a fiduciary duty claim on your behalf, including equity holders, employees or creditors, (c) you are capable of evaluating and understanding, and you understand and accept, the terms, risks and conditions of the transactions contemplated by this Commitment Letter and you have consulted with your own legal and financial advisors to the extent you have deemed appropriate and (d) you have been advised that each Commitment Party and its affiliates are engaged in a broad range of transactions that may involve interests that differ from your interests and that such Commitment Party has no obligation to disclose such interests and transactions to you by virtue of any fiduciary, advisory or agency relationship.
