(b) Each Underwriter, severally and not jointly, will indemnify and hold harmless the Company and the Joint Venture, each of their respective directors, officers and employees and each person, if any, who controls, as of the date hereof, the Company or the Joint Venture within the meaning of the Act and the Exchange Act against any losses, claims, damages or liabilities to which the Company or the Joint Venture may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus, or any roadshow or Section 5(d) Writing, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Registration Statement, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus, or any roadshow or Section 5(d) Writing, or in reliance upon and in conformity with the Underwriter Information; and will reimburse the Company and the Joint Venture for any legal or other expenses reasonably incurred by the Company and the Joint Venture in connection with investigating or defending any such action or claim as such expenses are incurred. As used in this Agreement with respect to an Underwriter and an applicable document, “Underwriter Information” shall mean the written information furnished to the Company by such Underwriter through the Representatives expressly for use therein; it being understood and agreed upon that the only such information furnished by any Underwriter consists of the following information in the Preliminary Prospectus and the Prospectus furnished on behalf of each Underwriter: the concession and reallowance figures appearing in the [fifth] paragraph under the caption “Underwriting”, and the information contained in the [ninth], [tenth] and [eleventh] paragraphs under the caption “Underwriting”.

(c) Promptly after receipt by an indemnified party under subsection (a) or (b) above of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify the indemnifying party in writing of the commencement thereof; provided that the failure to notify the indemnifying party shall not relieve it from any liability that it may have under the preceding paragraphs of this Section 9 except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided further that the failure

22

to notify the indemnifying party shall not relieve it from any liability that it may have to an indemnified party otherwise than under the preceding paragraphs of this Section 9. In case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and, after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party under such subsection for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation. It is understood that the indemnifying party or parties shall not, in connection with any one action or proceeding or separate but substantially similar actions or proceedings arising out of the same general allegations, be liable for the fees and expenses of more than one separate firm of attorneys at any time for all indemnified parties except to the extent that local counsel or counsel with specialized expertise (in addition to any regular counsel) is required to effectively defend against any such action or proceeding. No indemnifying party shall, without the written consent of the indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability arising out of such action or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any indemnified party.

(d) If the indemnification provided for in this Section 9 is unavailable to or insufficient to hold harmless an indemnified party under subsection (a) or (b) above in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the total relative benefits received by the Company and the Joint Venture on the one hand and the Underwriters on the other from the offering of the Shares. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law, then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the total relative fault of the Company and the Joint Venture on the one hand and the Underwriters on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations. The total relative benefits received by the Company and the Joint Venture on the one hand and the Underwriters on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (net of underwriting discounts and commissions but before deducting expenses) received by the Company bear to the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover page of the Prospectus. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or the Joint Venture on the one hand or the Underwriters on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company, the Joint Venture and the Underwriters agree that it would not be just and equitable if contribution pursuant to this subsection (d) were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by

23

any other method of allocation which does not take account of the equitable considerations referred to above in this subsection (d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this subsection (d), no Underwriter shall be required to contribute any amount in excess of the amount by which the total underwriting discounts and commissions received by such Underwriter with respect to the offering of the Shares to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations in this subsection (d) to contribute are several in proportion to their respective underwriting obligations and not joint.

(e) The obligations of the Company and the Joint Venture under this Section 9 shall be in addition to any liability which the Company or the Joint Venture may otherwise have and shall extend, upon the same terms and conditions, to each officer and director of each Underwriter and each person, if any, who controls any Underwriter within the meaning of the Act and each broker-dealer affiliate of any Underwriter; and the obligations of the Underwriters under this Section 9 shall be in addition to any liability which the respective Underwriters may otherwise have and shall extend, upon the same terms and conditions, to each officer and director of the Company (including any person who, with his or her consent, is named in the Registration Statement as about to become a director of the Company) and to each person, if any, who controls the Company within the meaning of the Act.

10. Directed Share Program Indemnification.

(a) Each of the Company and the Joint Venture will jointly and severally indemnify and hold harmless the Directed Share Underwriter, its affiliates, directors, officers and employees and each person, if any, who controls the Directed Share Underwriter within the meaning of the Act (each, a “Directed Share Underwriter Entity”), against any losses, claims, damages or liabilities, joint or several, to which the Directed Share Underwriter Entity may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) (i) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in any material prepared by or with the consent of the Company for distribution to Participants in connection with the Directed Share Program, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading; (ii) arise out of or are based upon the failure of any Participant to pay for and accept delivery of Directed Shares that the Participant agreed to purchase; or (iii) relate to, arise out of, are based upon or are in connection with the Directed Share Program, and will reimburse the Directed Share Underwriter Entities for any legal or other expenses reasonably incurred by the Directed Share Underwriter Entities in connection with investigating or defending any such action or claim as such expenses are incurred; provided, however, that the Company and the Joint Venture shall not be liable under this clause (iii) to the extent that any such loss, claim, damage or liability is finally judicially determined to have resulted from the bad faith or gross negligence of the Directed Share Underwriter Entities.

(b) Promptly after receipt by any Directed Share Underwriter Entity under subsection (a) above of notice of the commencement of any action, the Directed Share Underwriter Entity shall, if a claim in respect thereof is to be made against the indemnifying party under subsection (a), notify the indemnifying party in writing of the commencement thereof; provided that the failure

24

to notify the indemnifying party shall not relieve it from any liability that it may have under subsection (a) of this Section 10 except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided further that the failure to notify the indemnifying party shall not relieve it from any liability that it may have to the Directed Share Underwriter Entity otherwise than under subsection (a) of this Section 10. In case any such action shall be brought against any Directed Share Underwriter Entity and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to the Directed Share Underwriter Entity (who shall not, except with the consent of the Directed Share Underwriter Entity, be counsel to the indemnifying party), and, after notice from the indemnifying party to the Directed Share Underwriter Entity of its election so to assume the defense thereof, the indemnifying party shall not be liable to the Directed Share Underwriter Entity under subsection (a) for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by the Directed Share Underwriter Entity, in connection with the defense thereof other than reasonable costs of investigation. It is understood that the indemnifying party or parties shall not, in connection with any one action or proceeding or separate but substantially similar actions or proceedings arising out of the same general allegations, be liable for the fees and expenses of more than one separate firm of attorneys at any time for all Directed Share Underwriter Entities except to the extent that local counsel or counsel with specialized expertise (in addition to any regular counsel) is required to effectively defend against any such action or proceeding. No indemnifying party shall, without the written consent of the Directed Share Underwriter Entity, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not a Directed Share Underwriter Entity is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (i) includes an unconditional release of the Directed Share Underwriter Entities from all liability arising out of such action or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of a Directed Share Underwriter Entity.

(c) If the indemnification provided for in this Section 10 is unavailable to or insufficient to hold harmless a Directed Share Underwriter Entity in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by the Directed Share Underwriter Entity as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the total relative benefits received by the Company and the Joint Venture on the one hand and the Directed Share Underwriter Entities on the other from the offering of the Directed Shares. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law, then each indemnifying party shall contribute to such amount paid or payable by the Directed Share Underwriter Entity in such proportion as is appropriate to reflect not only such relative benefits but also the total relative fault of the Company and the Joint Venture on the one hand and the Directed Share Underwriter Entities on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations. The total relative benefits received by the Company and the Joint Venture on the one hand and the Directed Share Underwriter Entities on the other in connection with the offering of the Directed Shares shall be deemed to be in the same proportion as the total net proceeds from the offering of the Directed Shares (net of underwriting discounts and commissions but before deducting expenses) received by the Company bear to the total underwriting discounts and commissions received by the Directed Share Underwriter Entities for the Directed Shares. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material

25

fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or the Joint Venture on the one hand or the Directed Share Underwriter Entities on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company, the Joint Venture and the Directed Share Underwriter Entities agree that it would not be just and equitable if contribution pursuant to this subsection (c) were determined by pro rata allocation (even if the Directed Share Underwriter Entities were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this subsection (c). The amount paid or payable by the Directed Share Underwriter Entities as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this subsection (c) shall be deemed to include any legal or other expenses reasonably incurred by the Directed Share Underwriter Entities in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this subsection (c), no Directed Share Underwriter Entity shall be required to contribute any amount in excess of the amount by which the total underwriting discounts and commissions received by such Underwriter with respect to the offering of the Directed Shares to the public exceeds the amount of any damages which such Directed Share Underwriter Entity has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

(d) The obligations of the Company and the Joint Venture under this Section 10 shall be in addition to any liability which the Company or the Joint Venture may otherwise have. The indemnity and contribution provisions contained in this Section 10 shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of any Directed Share Underwriter Entity or the Company, the Joint Venture, each of their respective officers or directors or any person controlling with the Company or the Joint Venture and (iii) acceptance of and payment for any of the Directed Shares.

11.      (a) If any Underwriter shall default in its obligation to purchase the Shares which it has agreed to purchase hereunder at a Time of Delivery, the Representatives may in their discretion arrange for the Representatives or another party or other parties to purchase such Shares on the terms contained herein. If within thirty-six hours after such default by any Underwriter, the Representatives do not arrange for the purchase of such Shares, then the Company shall be entitled to a further period of thirty-six hours within which to procure another party or other parties reasonably satisfactory to the Representatives to purchase such Shares on such terms. In the event that, within the respective prescribed periods, the Representatives notify the Company that they have so arranged for the purchase of such Shares, or the Company notifies the Representatives that it has so arranged for the purchase of such Shares, the Representatives or the Company shall have the right to postpone such Time of Delivery for a period of not more than seven days, in order to effect whatever changes may thereby be made necessary in the Registration Statement or the Prospectus, or in any other documents or arrangements, and the Company agrees to file promptly any amendments or supplements to the Registration Statement or the Prospectus which in the Representatives’ opinion may thereby be made necessary. The term “Underwriter” as used in this Agreement shall include any person substituted under this Section with like effect as if such person had originally been a party to this Agreement with respect to such Shares.

(b) If, after giving effect to any arrangements for the purchase of the Shares of a defaulting Underwriter or Underwriters by the Representatives and the Company as provided in subsection (a) above, the aggregate number of such Shares which remains unpurchased does not exceed one-eleventh of the aggregate number of all the Shares to be purchased at such Time

26

of Delivery, then the Company shall have the right to require each non-defaulting Underwriter to purchase the number of Shares which such Underwriter agreed to purchase hereunder at such Time of Delivery and, in addition, to require each non-defaulting Underwriter to purchase its pro rata share (based on the number of Shares which such Underwriter agreed to purchase hereunder) of the Shares of such defaulting Underwriter or Underwriters for which such arrangements have not been made; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

(c) If, after giving effect to any arrangements for the purchase of the Shares of a defaulting Underwriter or Underwriters by the Representatives and the Company as provided in subsection (a) above, the aggregate number of such Shares which remains unpurchased exceeds one-eleventh of the aggregate number of all the Shares to be purchased at such Time of Delivery, or if the Company shall not exercise the right described in subsection (b) above to require non-defaulting Underwriters to purchase Shares of a defaulting Underwriter or Underwriters, then this Agreement (or, with respect to the Second Time of Delivery, the obligations of the Underwriters to purchase and of the Company to sell the Optional Shares) shall thereupon terminate, without liability on the part of any non-defaulting Underwriter or the Company, except for the expenses to be borne by the Company and the Underwriters as provided in Section 7 hereof and the indemnity and contribution agreements in Sections 9 and 10 hereof; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

12. The respective indemnities, rights of contribution, agreements, representations, warranties and other statements of the Company, the Joint Venture, the several Underwriters and the Directed Share Underwriter Entities, as set forth in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement, shall remain in full force and effect, regardless of any investigation (or any statement as to the results thereof) made by or on behalf of any Underwriter or any controlling person of any Underwriter, the Company or the Joint Venture, or any officer or director or controlling person of the Company or the Joint Venture, or any Directed Share Underwriter Entity, and shall survive delivery of and payment for the Shares.

13. If this Agreement shall be terminated pursuant to Section 11 hereof, the Company and the Joint Venture shall not then be under any liability to any Underwriter or Directed Share Underwriter Entity except as provided in Sections 7, 9 and 10 hereof; but, if for any other reason, any Shares are not delivered by or on behalf of the Company as provided herein, the Company and the Joint Venture jointly and severally agree to reimburse the Underwriters through the Representatives for all reasonable and documented out-of-pocket expenses approved in writing by the Representatives, including fees and disbursements of counsel, reasonably incurred by the Underwriters in making preparations for the purchase, sale and delivery of the Shares not so delivered, but the Company and the Joint Venture shall then be under no further liability to any Underwriter or Directed Share Underwriter Entity except as provided in Sections 7, 9 and 10 hereof.

14. In all dealings hereunder, the Representatives shall act on behalf of each of the Underwriters, and the parties hereto shall be entitled to act and rely upon any statement, request, notice or agreement on behalf of any Underwriter made or given by the Representatives.

All statements, requests, notices and agreements hereunder shall be in writing, and if to the Underwriters shall be delivered or sent by mail, telex or facsimile transmission to the Representatives in care of Barclays Capital Inc., 745 Seventh Avenue, New York, New York 10019, Attention: Syndicate Registration; Goldman Sachs & Co. LLC, 200 West Street, New York, New York 10282-2198, Attention: Registration Department and J.P. Morgan Securities LLC, 383 Madison Avenue, New York, New York 10179, Attention: Equity Syndicate Desk; and if to the Company or the Joint Venture shall be delivered or sent by mail, telex or facsimile transmission

27

to the address of the Company set forth in the Registration Statement, Attention: [General Counsel]; provided, however, that any notice to an Underwriter pursuant to Section 9(c) hereof shall be delivered or sent by mail, telex or facsimile transmission to such Underwriter at its address set forth in its Underwriters’ Questionnaire, or telex constituting such Questionnaire, which address will be supplied to the Company and the Joint Venture by the Representatives upon request; provided, however, that notices under subsection 5(e) shall be in writing, and if to the Underwriters shall be delivered or sent by mail, telex or facsimile transmission to the Representatives at Barclays Capital Inc., 745 Seventh Avenue, New York, New York 10019, Attention: Syndicate Registration; Goldman Sachs & Co. LLC, 200 West Street, New York, New York 10282-2198, Attention: Control Room and J.P. Morgan Securities LLC, 383 Madison Avenue, New York, New York 10179, Attention: Equity Syndicate Desk. Any such statements, requests, notices or agreements shall take effect upon receipt thereof.

In accordance with the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)), the Underwriters are required to obtain, verify and record information that identifies their respective clients, including the Company and the Joint Venture, which information may include the name and address of their respective clients, as well as other information that will allow the Underwriters to properly identify their respective clients.

15. Recognition of the U.S. Special Resolution Regimes. (a) In the event that any Underwriter that is a Covered Entity (as defined below) becomes subject to a proceeding under a U.S. Special Resolution Regime (as defined below), the transfer from such Underwriter of this Agreement, and any interest and obligation in or under this Agreement, will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if this Agreement, and any such interest and obligation, were governed by the laws of the United States or a state of the United States.

(b) In the event that any Underwriter that is a (b) Covered Entity or a BHC Act Affiliate of such Underwriter becomes subject to a proceeding under a U.S. Special Resolution Regime, Default Rights under this Agreement that may be exercised against such Underwriter are permitted to be exercised to no greater extent than such Default Rights (as defined below) could be exercised under the U.S. Special Resolution Regime if this Agreement were governed by the laws of the United States or a state of the United States.

(c) For purposes of this Section a “BHC Act Affiliate” has the meaning as signed to the term “affiliate” in, and shall be interpreted in accordance with, 12 U.S.C. § 1841(k). “Covered Entity” means any of the following: (i) a “covered entity” as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 252.82(b); (ii) a “covered bank” as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 47.3(b); or (iii) a “covered FSI” as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 382.2(b). “Default Right” has the meaning assigned to that term in, and shall be interpreted in accordance with, 12 C.F.R. §§ 252.81, 47.2 or 382.1, as applicable. “U.S. Special Resolution Regime” means each of (i) the Federal Deposit Insurance Act and the regulations promulgated thereunder and (ii) Title II of the Dodd-Frank Wall Street Reform and Consumer Protection Act and the regulations promulgated thereunder.

16. This Agreement shall be binding upon, and inure solely to the benefit of, the Underwriters, the Company, the Joint Venture and, to the extent provided in Sections 9, 10 and 12 hereof, the officers and directors of the Company and the Joint Venture and each person who controls the Company, the Joint Venture or any Underwriter, the Directed Share Underwriter Entities and their respective heirs, executors, administrators, successors and assigns, and no other person shall acquire or have any right under or by virtue of this Agreement. No purchaser of any of the Shares from any Underwriter shall be deemed a successor or assign by reason merely of such purchase.

28

17. Time shall be of the essence of this Agreement. As used herein, the term “business day” shall mean any day when the Commission’s office in Washington, D.C. is open for business.

18. Each of the Company and the Joint Venture acknowledges and agrees that (i) the purchase and sale of the Shares pursuant to this Agreement is an arm’s-length commercial transaction between the Company and the Joint Venture, on the one hand, and the several Underwriters, on the other, (ii) in connection therewith and with the process leading to such transaction each Underwriter is acting solely as a principal and not the agent or fiduciary of the Company or the Joint Venture, (iii) no Underwriter has assumed an advisory or fiduciary responsibility in favor of the Company or the Joint Venture with respect to the offering contemplated hereby or the process leading thereto (irrespective of whether such Underwriter has advised or is currently advising the Company of the Joint Venture on other matters) or any other obligation to the Company or the Joint Venture except the obligations expressly set forth in this Agreement and (iv) the Company and the Joint Venture have consulted their own legal and financial advisors to the extent they deemed appropriate. The Company and the Joint Venture agree that they will not claim that the Underwriters, or any of them, has rendered advisory services of any nature or respect, or owes a fiduciary or similar duty to the Company or the Joint Venture, in connection with such transaction or the process leading thereto.

19. This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Company, the Joint Venture and the Underwriters, or any of them, with respect to the subject matter hereof.

20. This Agreement and any transaction contemplated by this Agreement shall be governed by and construed in accordance with the laws of the State of New York without regard to principles of conflict of laws that would result in the application of any other law than the laws of the State of New York. The Company and the Joint Venture agree that any suit or proceeding arising in respect of this Agreement or any transaction contemplated by this Agreement will be tried exclusively in the U.S. District Court for the Southern District of New York or, if that court does not have subject matter jurisdiction, in any state court located in The City and County of New York and the Company and the Joint Venture agree to submit to the jurisdiction of, and to venue in, such courts.

21. The Company, the Joint Venture and each of the Underwriters hereby irrevocably waives, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.

22. This Agreement may be executed by any one or more of the parties hereto in any number of counterparts, each of which shall be deemed to be an original, but all such counterparts shall together constitute one and the same instrument.

23. Notwithstanding anything herein to the contrary, the Company and the Joint Venture are authorized to disclose to any persons the U.S. federal and state income tax treatment and tax structure of the potential transaction and all materials of any kind (including tax opinions and other tax analyses) provided to the Company or the Joint Venture relating to that treatment and structure, without the Underwriters imposing any limitation of any kind. However, any information relating to the tax treatment and tax structure shall remain confidential (and the foregoing sentence shall not apply) to the extent necessary to enable any person to comply with securities laws. For this purpose, “tax structure” is limited to any facts that may be relevant to that treatment.

29

If the foregoing is in accordance with the Representatives’ understanding, please sign and return to us five counterparts hereof, and upon the acceptance hereof by the Representatives, on behalf of each of the Underwriters, this letter and such acceptance hereof shall constitute a binding agreement between each of the Underwriters, the Company and the Joint Venture. It is understood that the Representatives’ acceptance of this letter on behalf of each of the Underwriters is pursuant to the authority set forth in a form of Agreement among Underwriters, the form of which shall be submitted to the Company and the Joint Venture for examination upon request, but without warranty on the part of the Representatives as to the authority of the signers thereof.

Re: Change Healthcare Inc.—Lock-Up Agreement

Ladies and Gentlemen:

The undersigned understands that you, as representatives (the “Representatives”), propose to enter into an Underwriting Agreement (the “Underwriting Agreement”) on behalf of the several Underwriters named in Schedule I to such agreement (collectively, the “Underwriters”), with Change Healthcare Inc., a Delaware corporation (the “Company”), providing for a public offering (the “Offering”) of the common stock, par value $0.001 (the “Stock”) of the Company (the “Shares”) pursuant to a Registration Statement on Form S-1 to be filed with the Securities and Exchange Commission (the “SEC”).

In consideration of the agreement by the Underwriters to offer and sell the Shares, and of other good and valuable consideration the receipt and sufficiency of which is hereby acknowledged, the undersigned agrees that, during the period beginning from the date of this Lock-Up Agreement and continuing to and including the date that is 180 days after the date set forth on the final prospectus used to sell the Shares (the “Lock-Up Period”), the undersigned will not offer, sell, contract to sell, pledge, grant any option to purchase, make any short sale or otherwise dispose of any shares of Stock of the Company, or any options or warrants to purchase any shares of Stock of the Company, or any securities convertible into, exchangeable for or that represent the right to receive shares of Stock of the Company (including, for clarity, limited liability company interests (the “LLC Units”) of Change Healthcare LLC (the “Joint Venture”)), whether now owned or hereinafter acquired, owned directly by the undersigned (including holding as a custodian) or with respect to which the undersigned has beneficial ownership within the rules and regulations of the SEC (collectively, the “Undersigned’s Shares”). The foregoing restriction is expressly agreed to preclude the undersigned from engaging in any hedging or other transaction which is designed to or which reasonably could be expected to lead to or result in a sale or disposition of the Undersigned’s Shares even if such Shares would be disposed of by someone other than the undersigned. Such prohibited hedging or other transactions would include without limitation any short sale or any purchase, sale or grant of any right (including without limitation any put or call option) with respect to any of the Undersigned’s Shares or with respect to any security

that includes, relates to, or derives any significant part of its value from such Shares. If the undersigned is an officer or director of the Company, the undersigned further agrees that the foregoing provisions shall be equally applicable to any issuer-directed Shares the undersigned may purchase in the Offering.

If the undersigned is an officer or director of the Company, (i) the Representatives agree that, at least three business days before the effective date of any release or waiver of the foregoing restrictions in connection with a transfer of shares of Common Stock, the Representatives will notify the Company of the impending release or waiver, and (ii) the Company has agreed in the Underwriting Agreement to announce the impending release or waiver by press release through a major news service at least two business days before the effective date of the release or waiver. Any release or waiver granted by the Representatives hereunder to any such officer or director shall only be effective two business days after the publication date of such press release. The provisions of this paragraph will not apply if (a) the release or waiver is effected solely to permit a transfer not for consideration and (b) the transferee has agreed in writing to be bound by the same terms described in this letter to the extent and for the duration that such terms remain in effect at the time of the transfer. [In addition, in the event of any release or waiver of the foregoing restrictions in respect of shares of Common Stock held by an affiliate of McKesson Corporation or a Sponsor (as defined in Section 1.1 of the Stockholders Agreement, dated as of March 1, 2017, by and among the Company, the Joint Venture, McKesson Corporation, and the other stockholders from time to time party thereto (as the same may be amended, supplemented, restated or otherwise modified from time to time), the Representatives agree that shares of Common Stock held by the undersigned shall similarly be released on a pro rata basis.]

Notwithstanding the foregoing, the undersigned may transfer the Undersigned’s Shares (i) by will or intestacy, (ii) as a bona fide gift or gifts, (iii) to any trust, partnership, limited liability company or other entity for the direct or indirect benefit of the undersigned or the immediate family of the undersigned, (iv) to any immediate family member or other dependent of the undersigned, (v) as a distribution to limited partners, members or stockholders of the undersigned, (vi) to the undersigned’s affiliates or to any investment fund or other entity controlled or managed by the undersigned, (vii) to a nominee or custodian of a person or entity to whom a disposition or transfer would be permissible under clauses (i) through (vi) above, (viii) pursuant to an order of a court or regulatory agency, (ix) from an executive officer to the Company or the Joint Venture upon death, disability or termination of employment, in each case, of such executive officer, (x) in connection with transactions by any person other than the Company relating to Shares acquired in open market transactions after the completion of the Offering, provided that in the case of this clause (x) no public reports or filings (including filings under Section 16(a) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) reporting a reduction in beneficial ownership of Stock shall be required or shall be voluntarily made during the Lock-Up Period or any extension thereof, (xi) to the Company pursuant to the “cashless” exercise at expiration of options granted pursuant to any employee equity incentive plan of the Company outstanding at or prior to the Time of Delivery and referred to in the Registration Statement, the Pricing Disclosure Package and the Prospectus (each, an “Incentive Plan”), provided that any shares of Stock or LLC Units received in connection therewith shall be subject to the terms of this Lock-up Agreement, (xii) in respect of tax withholding payments due upon the exercise at expiration of options or the vesting of restricted stock grants pursuant to any Incentive Plan, provided that any filings required to be made with the SEC or other publicity made regarding the same will indicate that such transactions relate to such tax withholding payments, [(xiii) through the pledge, hypothecation or other granting of a security interest in Stock to one or more banks or financial institutions as collateral or security for any loan,

advance or extension of credit and any transfer upon foreclosure upon such shares or thereafter, provided that the undersigned or the Company, as the case may be, shall provide the Representatives prior written notice informing it of any public filing, report or announcement made by or on behalf of the Company or the undersigned with respect thereto] and/or [(xiii)][(xiv)] with the prior written consent of each of the Representatives on behalf of the Underwriters; provided that:

[Notwithstanding the foregoing, clauses (1)(a) and 2(b) above shall not apply with respect to any transfer of shares of Stock to charitable organization transferees or recipients (including any direct or indirect member or partner of the undersigned that receives such shares of Stock pursuant to a distribution in-kind to such member or partner and is subject to restrictions requiring such shares of Stock to be transferred only to charitable organizations pursuant to clause (ii) above) in an aggregate amount, together with any such transfers pursuant to any substantially similar lock-up agreement with the Representatives, not to exceed 1.0% of the Common Stock then outstanding (treating as outstanding, shares of Common Stock issuable on exchange of LLC Units in the Joint Venture not held by the Company).]

In addition, notwithstanding the foregoing, if the undersigned is a corporation, the corporation may transfer the capital stock of the Company to any wholly owned subsidiary of such corporation; provided, however, that in any such case, it shall be a condition to the transfer that the transferee execute an agreement stating that the transferee is receiving and holding such capital stock subject to the provisions of this Lock-Up Agreement and there shall be no further transfer of such capital stock except in accordance with this Lock-Up Agreement, and provided further that any such transfer shall not involve a disposition for value.

The restrictions described in this Lock-Up Agreement shall not apply to the establishment of a trading plan pursuant to Rule 10b5-1 under the Exchange Act, provided that no transfers occur under such plan during the Lock-Up Period and no public announcement or filing shall be required or voluntarily made by any person in connection therewith other than general disclosure in Company periodic reports to the effect that Company directors and officers may enter into such trading plans from time to time.

For purposes of this Lock-Up Agreement, “immediate family” shall mean any relationship by blood, marriage or adoption, not more remote than first cousin.

The undersigned now has, and, except as contemplated by clause (i), (ii), or (iii) above, for the duration of this Lock-Up Agreement will have, good and marketable title to the Undersigned’s Shares, free and clear of all liens, encumbrances, and claims whatsoever. The undersigned also agrees and consents to the entry of stop transfer instructions with the Company’s transfer agent and registrar against the transfer of the Undersigned’s Shares except in compliance with the foregoing restrictions.

The undersigned understands that, if (i) the Underwriting Agreement (other than the provisions which survive termination under the terms thereof) shall terminate or be terminated prior to payment for the delivery of the Shares to be sold thereunder, (ii) the Registration Statement is withdrawn by the Company, (iii) the Company notifies the Representatives that it does not intend to proceed with the Offering, or (iv) the Underwriting Agreement is not executed by [                     ], the undersigned shall be released from all obligations under this Lock-Up Agreement and this Lock-Up Agreement shall be of no further effect.

The undersigned further understands that this Lock-Up Agreement is irrevocable and shall be binding upon the undersigned’s heirs, legal representatives, successors, and assigns.
