Ladies and Gentlemen:

Emdeon Inc., a Delaware corporation (the “Company”), proposes to issue and sell to the several Underwriters named in Schedule II hereto (the “Underwriters”), and certain shareholders of the Company (the “Selling Shareholders”) named in Schedule I hereto severally propose to sell to the several Underwriters, an aggregate of [ ] shares of Class A Common Stock, par value $0.00001 per share, of the Company (the “Firm Shares”), of which [ ] shares are to be issued and sold by the Company and [ ] shares are to be sold by the Selling Shareholders, each Selling Shareholder selling the amount set forth opposite such Selling Shareholder’s name in Schedule I hereto. Defined terms used but not otherwise defined herein have the meaning ascribed thereto in the Time of Sale Prospectus (as defined below).

The Selling Shareholders also propose to issue and sell to the several Underwriters not more than an additional [ ] shares of the Company’s Class A Common Stock, par value $0.00001 per share (the “Additional Shares”), if and to the extent that you, as managers of the offering, shall have determined to exercise, on behalf of the Underwriters, the right to

purchase such shares of common stock granted to the Underwriters in Section 3 hereof. The Firm Shares and the Additional Shares are hereinafter collectively referred to as the “Shares.” The shares of Class A Common Stock, par value $0.00001, of the Company to be outstanding after giving effect to the sales contemplated hereby are hereinafter referred to as the “Class A Common Stock.” The Company and the Selling Shareholders are hereinafter sometimes collectively referred to as the “Sellers.”

The Company has filed with the Securities and Exchange Commission (the “Commission”) a registration statement, including a prospectus, relating to the Shares. The registration statement as amended at the time it becomes effective (the “Effective Date”), including the information (if any) deemed to be part of the registration statement at the time of effectiveness pursuant to Rule 430A under the Securities Act of 1933, as amended (the “Securities Act”), is hereinafter referred to as the “Registration Statement”; each prospectus included in such registration statement (and any amendments thereto) before it becomes effective, any prospectus filed with the Commission pursuant to Rule 424(a) under the Securities Act and the prospectus included in the Registration Statement at the time of its effectiveness pursuant to Rule 430A is hereinafter referred to as a “preliminary prospectus”; the prospectus in the form first used to confirm sales of Shares (or in the form first made available to the Underwriters by the Company to meet requests of purchasers pursuant to Rule 173 under the Securities Act) is hereinafter referred to as the “Prospectus.” If the Company has filed an abbreviated registration statement to register additional shares of Class A Common Stock pursuant to Rule 462(b) under the Securities Act (the “Rule 462 Registration Statement”), then any reference herein to the term “Registration Statement” shall be deemed to include such Rule 462 Registration Statement.

For purposes of this Agreement, “free writing prospectus” has the meaning set forth in Rule 405 under the Securities Act, “Time of Sale Prospectus” means the preliminary prospectus together with the free writing prospectuses, if any, each identified in Schedule III hereto, and “broadly available road show” means a “bona fide electronic road show” as defined in Rule 433(h)(5) under the Securities Act that has been made available without restriction to any person. As used herein, the terms “Registration Statement,” “preliminary prospectus,” “Time of Sale Prospectus” and “Prospectus” shall include the documents, if any, incorporated by reference therein.

The transactions set forth in this paragraph and described more fully in the Time of Sale Prospectus under “Organizational Structure” are referred to collectively as the “Reorganization Transactions.” Prior to the date hereof, the limited liability agreement of the Company’s subsidiary, EBS Master LLC (the “LLC”) has been amended such that the Company has become the sole managing member of the LLC. The Company has amended and restated its certificate of incorporation and reclassified the common stock held by its stockholders into an aggregate of [ ] shares of Class A Common Stock. The Company has redeemed from its stockholders [ ] shares of its

Class A common stock in exchange for the rights by its stockholders to receive payments under one of the tax receivable agreements with the Tax Receivable Entity (which rights were then immediately contributed (directly or indirectly) by the Company’s stockholders to the Tax Receivable Entity). Pursuant to the merger of EBS Acquisition II LLC and EBS Holdco I, LLC, a wholly owned subsidiary of the Company, EBS Acquisition II LLC’s members, all of whom are investment funds organized and controlled by General Atlantic, received an aggregate of [ ] shares of Class A Common Stock and rights to receive payments under one of the tax receivable agreements with the Tax Receivable Entity (which rights were then immediately contributed (directly or indirectly) to the Tax Receivable Entity, in exchange for their former indirect interest in the LLC) and EBS Holdco I, LLC remained as the surviving corporation. Pursuant to the merger of H&F Harrington AIV II, L.P. with EBS Holdco II, LLC, a wholly owned subsidiary of the Company, H&F Harrington AIV II, L.P. received an aggregate of [ ] shares of Class A Common Stock and rights to receive payments under one of the tax receivable agreements with the Tax Receivable Entity (which rights were then immediately contributed (directly or indirectly) to the Tax Receivable Entity, in exchange for Harrington AIV II, L.P.’s former indirect interest in the LLC) and EBS Holdco II, LLC remained as the surviving corporation. Each of the H&F Continuing LLC Members continue to hold an aggregate of [ ] EBS Units, and were issued [ ] shares of the Company’s Class B Common Stock, par value $0.00001 per share, which have voting but no economic rights (the “Class B Common Stock”), and also received rights to enter into one of the tax receivable agreements with the Tax Receivable Entity (which rights were then immediately contributed (directly or indirectly) to the Tax Receivable Entity). The eRX Members continue to hold an aggregate of [ ] EBS Units and were issued an aggregate of [ ] shares of Class B Common Stock. Additionally, the LLC will amend the Fifth Amended and Restated EBS Master LLC limited liability company agreement such that, after the Effective Date but before the Closing Date (as defined in Section 5), Grant Units since the date of grant will be converted into [ ] vested and unvested EBS Units, and the right to enter into a tax receivable agreement with the Company (the “TRA Rights”), which vested and unvested EBS Units and TRA Rights will be distributed to participants in the EBS Master Amended and Restated Equity Incentive Plan (the “EBS Equity Plan Members”). EBS Equity Plan Members (other than the Company’s directors) will also be granted unvested options to purchase an aggregate of [ ] shares of Class A Common Stock, at the initial public offering price in respect of Grant Units. The Company will also issue [ ] shares of Class B Common Stock to recipients of EBS Units pursuant to the foregoing sentence. Subsequent to the date hereof but before the Closing Date, the Company, in its capacity as managing member of the LLC, will cause the vested EBS Phantom Awards to be converted into [ ] shares of the Company’s Class A Common Stock and the unvested EBS Phantom Awards to be converted into [ ] unvested restricted stock unit awards, which will entitle a holder of such unvested

restricted stock unit awards to receive shares of Class A Common Stock upon vesting. In addition, the Company will issue the EBS Phantom Plan Participants unvested options to purchase [____________] shares of Class A Common Stock at the initial public offering price. The Company will also enter into a Unit Purchase Agreement with certain of the EBS Equity Plan Members, pursuant to which it will purchase EBS Units and shares of Class B common stock from the EBS Equity Plan Members using proceeds it receives from the Firm Shares. The documents set forth on Schedule IV hereto, which have been, or will be, amended or entered into, as applicable, pursuant to the Reorganization Transactions are referred to as the “Reorganization Documents”.

[ ] (“DSP Bank”) has agreed to reserve a portion of the Shares to be purchased by it under this Agreement for sale to the Company’s directors, officers, employees and business associates and other parties related to the Company (collectively, “Participants”), as set forth in the Prospectus under the heading “Underwriters” (the “Directed Share Program”). The Shares to be sold by DSP Bank and its affiliates pursuant to the Directed Share Program are referred to hereinafter as the “Directed Shares”. Any Directed Shares not orally confirmed for purchase by any Participant by the end of the business day on which this Agreement is executed will be offered to the public by the Underwriters as set forth in the Prospectus.

(ii) The statistical and market and industry-related data included in the Registration Statement, the Time of Sale Prospectus and the Prospectus, other than the data furnished to the Company and the LLC by the Underwriters specifically for use therein, are based on or derived from sources that the Company reasonably believes to be reliable and accurate in all material respects.

(jj) The Company and each of its subsidiaries have filed all federal, state, local and foreign tax returns required to be filed through the date of this Agreement or have requested extensions thereof (except where the failure to file would not, individually or in the aggregate, have a Material Adverse Effect) and have paid all taxes required to be paid thereon (except for cases in which the failure to file or pay would not have a Material Adverse Effect, or, except as currently being contested in good faith and for which reserves required by U.S. GAAP have been created in the financial statements of the Company), and no tax deficiency has been determined adversely to the Company or any of its subsidiaries which has had (nor does the Company nor any of its subsidiaries have any notice or knowledge of any tax deficiency which could reasonably be expected to be determined adversely to the Company or its subsidiaries and which could reasonably be expected to have) a Material Adverse Effect.

(kk) Except as described in the Time of Sale Prospectus and the Registration Statement, the Company has not sold, issued or distributed any shares of common stock during the six-month period preceding the date hereof, including any sales pursuant to Rule 144A under, or Regulation D or S of, the Securities Act, other than shares issued pursuant to employee benefit plans, qualified stock option plans or other employee compensation plans or pursuant to outstanding options, rights or warrants.

(ll) The Company and the Company’s subsidiaries, as applicable, have duly authorized and, by the Closing Date shall have executed and delivered, each of the Reorganization Documents to which it is a party; each of the

3. Agreements to Sell and Purchase. Each Seller, severally and not jointly, hereby agrees to sell to the several Underwriters, and each Underwriter, upon the basis of the representations and warranties herein contained, but subject to the conditions hereinafter stated, agrees, severally and not jointly, to purchase from such Seller at $[ ] a share (the “Purchase Price”) the number of Firm Shares (subject to such adjustments to eliminate fractional shares as you may determine) that bears the same proportion to the number of Firm Shares to be sold by such Seller as the number of Firm Shares set forth in Schedule II hereto opposite the name of such Underwriter bears to the total number of Firm Shares.

On the basis of the representations and warranties contained in this Agreement, and subject to its terms and conditions, the Selling Shareholders agree to sell to the Underwriters the Additional Shares, and the Underwriters shall have the right to purchase, severally and not jointly, up to [ ] Additional Shares at the Purchase Price. You may exercise this right on behalf of the Underwriters in whole or from time to time in part by giving written notice not later than 30 days after the date of this Agreement.

The number of Additional Shares to be purchased from each Selling Shareholder, by the Underwriters, collectively, shall equal the number of Additional Shares to be purchased from Selling Shareholders collectively multiplied by the fraction obtained by dividing the number of Additional Shares to be sold by such Selling Shareholder, as indicated on Schedule I hereto, by the total number of Additional Shares, as indicated on Schedule I hereto (subject to such adjustments to eliminate fractional shares as you may determine). The number of such Additional Shares to be sold by each Selling Shareholder and purchased by each Underwriter from each Selling Shareholder shall be the number of Additional Shares (subject to such adjustments to eliminate fractional shares as you may determine) that bears the same proportion to the number of Additional Shares to be sold by such Selling Shareholder as the number of Additional Shares set forth in Schedule II hereto opposite the name of such Underwriter bears to the total number of Additional Shares set forth in Schedule II hereto.

Additional Shares may be purchased as provided in Section 5 hereof solely for the purpose of covering over-allotments, if any, made in connection with the offering

The Company hereby agrees that, without the prior written consent of each of Morgan Stanley & Co. Incorporated, Goldman, Sachs & Co., UBS Securities LLC and Barclays Capital Inc.

the Sixth Amended and Restated Limited Liability Company Agreement of the LLC filed as an exhibit to the Registration Statement; provided in the case of this clause (f) that no filing under Section 16(a) of the Exchange Act, reporting a change in beneficial ownership of shares of Class A Common Stock or securities convertible into or exercisable or exchangeable for Class A Common Stock, shall be required or shall be voluntarily made during such 180-day period or (g) the issuance by the Company of Class A Common Stock or securities convertible into Common Stock in connection with an acquisition or business combination (including the filing of a registration statement on Form S-4 or any other appropriate form with respect thereto); provided that such issuances are limited in the aggregate to an amount equal to 5% of the total shares of Class A Common Stock outstanding immediately after the completion of the offering (assuming the exchange for shares of Class A Common Stock of all membership units in the LLC and shares of Class B Common Stock outstanding immediately after the completion of the offering) and provided further that recipients of such Class A Common Stock agree to be bound by the terms of the lock-up letter substantially in the form of Exhibit A hereto.

(d) In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to Section 10(a), 10(b) or 10(c), such person (the “indemnified party”) shall promptly notify the person against whom such indemnity may be sought (the “indemnifying party”) in writing, but the failure to so notify the indemnifying party shall not relieve it from any liability it may have under Sections 10(a), 10(b) or 10(c) above except to the extent that the indemnifying party has been materially prejudiced (through forfeiture of substantive rights or defenses) by such failure and in any event the indemnifying party shall not be relieved from any liability which it may have otherwise than on account of Sections 10(a), 10(b) or 10(c) above, and the indemnifying party, upon request of the indemnified party, shall retain counsel reasonably satisfactory to the indemnified party to represent the indemnified party and any others the indemnifying party may designate in such proceeding and shall pay the fees and disbursements of such counsel related to such proceeding. In any such proceeding, any indemnified party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel or (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be in the reasonable judgment of counsel inappropriate due to actual or potential differing interests between them. It is understood that the indemnifying party shall not, in respect of the legal expenses of any indemnified party in connection with any proceeding or related proceedings in the same jurisdiction, be liable for (i) the reasonably incurred fees and expenses of more than one separate firm (in addition to any local counsel) for all Underwriters and all persons, if any, who control any Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act or who are affiliates of any Underwriter within the meaning of Rule 405 under the Securities Act, (ii) the reasonably incurred fees and expenses of more than one separate firm (in addition to any local counsel) for the Company, its directors, its officers who sign the Registration Statement and each person, if any, who controls the Company within the meaning of either such Section and (iii) the reasonably incurred fees and expenses of more than one separate firm (in addition to any local counsel) for all Selling Shareholders and all persons, if any, who control any Selling Shareholder within the meaning of either such Section, and that all such fees and expenses shall be reimbursed as they are incurred. In the case of any such separate firm for the Underwriters and such control persons and affiliates of any Underwriters, such firm shall be designated in writing by the Representatives. In the case of any such separate firm for the Company, and such

directors, officers and control persons of the Company, such firm shall be designated in writing by the Company. In the case of any such separate firm for the Selling Shareholders and such control persons of any Selling Shareholders, such firm shall be designated in writing by the mutual agreement of the Selling Shareholders. The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by the second and third sentences of this paragraph, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 60 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless (i) such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding 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.

(e) To the extent the indemnification provided for in Section 10(a), 10(b) or 10(c) is unavailable to an indemnified party or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each indemnifying party under such paragraph, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the indemnifying party or parties on the one hand and the indemnified party or parties on the other hand from the offering of the Shares or (ii) if the allocation provided by clause 10(e)(i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause 10(e)(i) above but also the relative fault of the indemnifying party or parties on the one hand and of the indemnified party or parties on the other hand in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Sellers on the one hand and the Underwriters on the other hand in connection with the offering of the Shares shall be deemed to be in the same respective proportions as the net proceeds from the offering of the Shares (before deducting expenses) received by each Seller and the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover of the Prospectus, bear to the aggregate Public Offering

Price of the Shares. The relative fault of the Sellers on the one hand and the Underwriters on the other hand 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 Sellers and the LLC or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Underwriters’ respective obligations to contribute pursuant to this Section 10 are several in proportion to the respective number of Shares they have purchased hereunder, and not joint. The liability of each Selling Shareholder under the contribution agreement contained in this paragraph shall be several and limited to an amount equal to the aggregate Public Offering Price of the Shares less the underwriting discounts and commissions sold by such Selling Shareholder under this Agreement.

(f) The Sellers and the Underwriters agree that it would not be just or equitable if contribution pursuant to this Section 10 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in Section 10(e). The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in Section 10(e) shall be deemed to include, subject to the limitations set forth above, 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 Section 10, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Shares underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages that 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 Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The remedies provided for in this Section 10 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity.

(g) The indemnity and contribution provisions contained in this Section 10 and the representations, warranties and other statements of the Company and the Selling Shareholders contained in this Agreement shall remain operative and in full force and effect regardless of (i) any termination of this Agreement or the Inducement Agreement, (ii) any investigation made by or on behalf of any Underwriter, any person controlling any Underwriter or any affiliate of any Underwriter, any Selling Shareholder or any person controlling any Selling Shareholder, or the Company, its officers or directors or any person controlling the Company and (iii) acceptance of and payment for any of the Shares.

11. Directed Share Program Indemnification. (a) The Company agrees to indemnify and hold harmless DSP Bank, each person, if any, who controls DSP

Bank within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act and each affiliate of DSP Bank within the meaning of Rule 405 of the Securities Act (“DSP Bank Entities”) from and against any and all losses, claims, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim) (i) caused by any untrue statement or alleged untrue statement of a material fact contained in any material prepared by or with the consent of the Company or the LLC for distribution to Participants in connection with the Directed Share Program or caused by any 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) caused by the failure of any Participant to pay for and accept delivery of Directed Shares that the Participant agreed to purchase; or (iii) related to, arising out of, or in connection with the Directed Share Program, other than losses, claims, damages or liabilities (or expenses relating thereto) that are finally judicially determined to have resulted from the bad faith or gross negligence of DSP Bank Entities.

(b) In case any proceeding (including any governmental investigation) shall be instituted involving any DSP Bank Entity in respect of which indemnity may be sought pursuant to Section 11(a), the DSP Bank Entity seeking indemnity, shall promptly notify the Company in writing and the Company, upon request of the DSP Bank Entity, shall retain counsel reasonably satisfactory to the DSP Bank Entity to represent the DSP Bank Entity and any others the Company may designate in such proceeding and shall pay the fees and disbursements of such counsel related to such proceeding. In any such proceeding, any DSP Bank Entity shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such DSP Bank Entity unless (i) the Company shall have agreed to the retention of such counsel or (ii) the named parties to any such proceeding (including any impleaded parties) include both the Company and the DSP Bank Entity and representation of both parties by the same counsel would be in the reasonable judgment of counsel inappropriate due to actual or potential differing interests between them. The Company shall not, in respect of the legal expenses of the DSP Bank Entities in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the reasonably incurred fees and expenses of more than one separate firm (in addition to any local counsel) for all DSP Bank Entities. Any such separate firm for the DSP Bank Entities shall be designated in writing by DSP Bank. The Company shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the Company agrees to indemnify the DSP Bank Entities from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time a DSP Bank Entity shall have requested the Company to reimburse it for fees and expenses of counsel as contemplated by the second and third sentences of this paragraph, the Company agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 60 days after receipt by the Company of the aforesaid request and (ii) the Company shall not have reimbursed the DSP Bank

Entity in accordance with such request prior to the date of such settlement. The Company shall not, without the prior written consent of DSP Bank, effect any settlement of any pending or threatened proceeding in respect of which any DSP Bank Entity is or could have been a party and indemnity could have been sought hereunder by such DSP Bank Entity, unless such settlement includes an unconditional release of the DSP Bank Entities from all liability on claims that are the subject matter of such proceeding.

(c) To the extent the indemnification provided for in Section 11(a) is unavailable to a DSP Bank Entity or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then the Company in lieu of indemnifying the DSP Bank Entity thereunder, shall contribute to the amount paid or payable by the DSP Bank Entity as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the DSP Bank Entities on the other hand from the offering of the Directed Shares or (ii) if the allocation provided by clause 11(c)(1) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause 11(c)(1) above but also the relative fault of the Company on the one hand and of the DSP Bank Entities on the other hand in connection with any statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the DSP Bank Entities on the other hand in connection with the offering of the Directed Shares shall be deemed to be in the same respective proportions as the net proceeds from the offering of the Directed Shares (before deducting expenses) and the total underwriting discounts and commissions received by the DSP Bank Entities for the Directed Shares, bear to the aggregate Public Offering Price of the Directed Shares. If the loss, claim, damage or liability is caused by an untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact, the relative fault of the Company on the one hand and the DSP Bank Entities on the other hand shall be determined by reference to, among other things, whether the untrue or alleged untrue statement or the omission or alleged omission relates to information supplied by the Company and the LLC or by the DSP Bank Entities and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(d) The Company and the DSP Bank Entities agree that it would not be just or equitable if contribution pursuant to this Section 11 were determined by pro rata allocation (even if the DSP Bank Entities were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in Section 11(b). The amount paid or payable by the DSP Bank Entities as a result of the losses, claims, damages and liabilities referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by the DSP Bank Entities in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this

Section 11, no DSP Bank Entity shall be required to contribute any amount in excess of the amount by which the total price at which the Directed Shares distributed to the public were offered to the public exceeds the amount of any damages that such DSP Bank Entity has otherwise been required to pay. The remedies provided for in this Section 11 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity.

(e) The indemnity and contribution provisions contained in this Section 11 shall remain operative and in full force and effect regardless of (i) any termination of this Agreement or the Inducement Agreement, (ii) any investigation made by or on behalf of any DSP Bank Entity, the Company, its officers or directors or any person controlling the Company and (iii) acceptance of and payment for any of the Directed Shares.

12. Termination. The Underwriters may terminate this Agreement by notice given by you to the Company, if after the execution and delivery of this Agreement and prior to the Closing Date (i) trading generally shall have been suspended or materially limited on, or by, as the case may be, any of the New York Stock Exchange, the American Stock Exchange, the NASDAQ Global Market, the Chicago Board of Options Exchange, the Chicago Mercantile Exchange or the Chicago Board of Trade, (ii) trading of any securities of the Company shall have been suspended on any exchange or in any over-the-counter market, (iii) a material disruption in securities settlement, payment or clearance services in the United States shall have occurred, (iv) any moratorium on commercial banking activities shall have been declared by Federal or New York State authorities or (v) there shall have occurred any outbreak or escalation of hostilities, or any change in financial markets or any calamity or crisis that, in your judgment, is material and adverse and which, singly or together with any other event specified in this clause (v), makes it, in your judgment, impracticable or inadvisable to proceed with the offer, sale or delivery of the Shares on the terms and in the manner contemplated in the Time of Sale Prospectus or the Prospectus.

13. Effectiveness; Defaulting Underwriters. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

If, on the Closing Date, or an Option Closing Date, as the case may be, any one or more of the Underwriters shall fail or refuse to purchase Shares that it has or they have agreed to purchase hereunder on such date, and the aggregate number of Shares which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase is not more than one-tenth of the aggregate number of the Shares to be purchased on such date, the other Underwriters shall be obligated severally in the proportions that the number of Firm Shares set forth opposite their respective names in Schedule II bears to the aggregate number of Firm Shares set forth opposite the names of all such non-defaulting Underwriters, or in such other proportions as you may specify, to purchase the Shares which

such defaulting Underwriter or Underwriters agreed but failed or refused to purchase on such date; provided that in no event shall the number of Shares that any Underwriter has agreed to purchase pursuant to this Agreement be increased pursuant to this Section 13 by an amount in excess of one-ninth of such number of Shares without the written consent of such Underwriter. If, on the Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase Firm Shares and the aggregate number of Firm Shares with respect to which such default occurs is more than one-tenth of the aggregate number of Firm Shares to be purchased on such date, and arrangements satisfactory to you, the Company and the Selling Shareholders for the purchase of such Firm Shares are not made within 36 hours after such default, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter, the Company or the Selling Shareholders. In any such case either you or the relevant Sellers shall have the right to postpone the Closing Date, but in no event for longer than seven days, in order that the required changes, if any, in the Registration Statement, in the Time of Sale Prospectus, in the Prospectus or in any other documents or arrangements may be effected. If, on an Option Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase Additional Shares and the aggregate number of Additional Shares with respect to which such default occurs is more than one-tenth of the aggregate number of Additional Shares to be purchased on such Option Closing Date, the non-defaulting Underwriters shall have the option to (i) terminate their obligation hereunder to purchase the Additional Shares to be sold on such Option Closing Date or (ii) purchase not less than the number of Additional Shares that such non-defaulting Underwriters would have been obligated to purchase in the absence of such default. Any action taken under this paragraph shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement.

If this Agreement shall be terminated by the Underwriters, or any of them, because of any failure or refusal on the part of any Seller to comply with the terms or to fulfill any of the conditions of this Agreement, or if for any reason any Seller shall be unable to perform its obligations under this Agreement, the Company will reimburse the Underwriters or such Underwriters as have so terminated this Agreement with respect to themselves, severally, for all documented out-of-pocket expenses (including the fees and disbursements of their counsel) reasonably incurred by such Underwriters in connection with this Agreement or the offering contemplated hereunder.

14. Entire Agreement. (a) This Agreement, together with any contemporaneous written agreements and any prior written agreements (to the extent not superseded by this Agreement) that relate to the offering of the Shares, represents the entire agreement between the Company and the Selling Shareholders, on the one hand, and the Underwriters, on the other, with respect to the preparation of any preliminary prospectus, the Time of Sale Prospectus, the Prospectus, the conduct of the offering, and the purchase and sale of the Shares, it being understood that the Underwriters and the LLC will enter into the Inducement Agreement on the Closing Date.

(b) The Company acknowledges that in connection with the offering of the Shares: (i) the Underwriters have acted at arms length, are not agents of, and owe no fiduciary duties to, the Company, the LLC or any other person, (ii) the Underwriters owe the Company and the LLC only those duties and obligations set forth in this Agreement and prior written agreements (to the extent not superseded by this Agreement), if any, and (iii) the Underwriters may have interests that differ from those of the Company and the LLC. The Company waives to the full extent permitted by applicable law any claims it may have against the Underwriters arising from an alleged breach of fiduciary duty in connection with the offering of the Shares.

15. Counterparts. This Agreement may be signed in two or more counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument.

16. Applicable Law. This Agreement shall be governed by and construed in accordance with the internal laws of the State of New York.

17. Headings. The headings of the sections of this Agreement have been inserted for convenience of reference only and shall not be deemed a part of this Agreement.

18. Notices. All communications hereunder shall be in writing and effective only upon receipt and if to the Underwriters shall be delivered, mailed or sent to the Representatives in care of Morgan Stanley & Co.

Ladies and Gentlemen:

The undersigned understands that Morgan Stanley & Co. Incorporated, Goldman, Sachs & Co., UBS Securities LLC and Barclays Capital Inc. ( the “Representatives”) propose to enter into an Underwriting Agreement (the “Underwriting Agreement”) with Emdeon Inc., a Delaware corporation (the “Company”), providing for the public offering (the “Public Offering”) by the several Underwriters listed in Schedule II thereto, including the Representatives (the “Underwriters”), of shares (the “Shares”) of Class A common stock, par value $0.00001 per share, of the Company (the “Class A Common Stock”).

To induce the Underwriters that may participate in the Public Offering to continue their efforts in connection with the Public Offering, the undersigned hereby agrees that, without the prior written consent of the Representatives on behalf of the Underwriters, it will not, during the period (the “Lock-Up Period”) commencing on the date hereof and ending 180 days after the date of the final prospectus relating to the Public Offering, (1) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend or otherwise transfer or dispose of, directly or indirectly, any shares of Class A Common Stock or any securities convertible into or exercisable or exchangeable for Class A Common Stock or any membership interests of Emdeon Master LLC (the “LLC”) or (2) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of the Class A Common Stock or any securities convertible into or exercisable or exchangeable for Class A Common Stock or membership interests of the LLC, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Class A Common Stock, membership interests of the LLC or such other

A-1

securities, in cash or otherwise. The foregoing sentence shall not apply to (a) transactions relating to shares of Class A Common Stock, any membership interests of the LLC or other securities acquired in open market transactions after the completion of the Public Offering, (b) transfers of shares of Class A Common Stock or any security convertible into or exercisable or exchangeable for Class A Common Stock or membership interests of the LLC (1) as a bona fide gift, (2) to any beneficiary of the undersigned pursuant to a will, other testamentary document or applicable laws of descent or (3) to a family member or trust; provided that in the case of any transfer or distribution pursuant to this clause (b), (i) each donee, beneficiary or transferee shall sign and deliver a lock-up letter substantially in the form of this letter and (ii) no filing under Section 16(a) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), reporting a reduction in beneficial ownership of shares of Class A Common Stock or securities convertible into or exercisable or exchangeable for Class A Common Stock, shall be required or shall be voluntarily made during the Lock-Up Period (other than a filing on Form 5 when required); provided, further, that in the case of transferees that are charitable organizations or trusts that receive Class A Common Stock or securities convertible into or exercisable or exchangeable for Class A Common Stock from General Atlantic LLC or any of its affiliates (the “General Atlantic entities”), the lock-up letters applicable to such entities will permit such transferees to collectively sell under Rule 144 under the Securities Act of 1933, as amended, up to an aggregate number of shares of Class A Common Stock equal to 1.0% of the shares outstanding immediately prior to the Public Offering, provided that such sales are made only through the Representatives, [or] (c) the establishment of a trading plan pursuant to Rule 10b5-1 under the Exchange Act, for the transfer of shares of Class A Common Stock, provided that such plan does not provide for the transfer of Class A Common Stock during the Lock-Up Period[, or (d) any pledge of Class A Common Stock by GapStar, LLC in favor of the lenders under its credit facilities, as existing on the date hereof, or any transfer of Class A Common Stock in connection with such pledge]¹. In addition, notwithstanding the foregoing, if the undersigned is a corporation, partnership or limited liability company, such entity (and its transferees or distributees) may transfer or distribute Class A Common Stock or securities convertible into or exercisable or exchangeable for Class A Common Stock or membership interests of the LLC to any wholly-owned subsidiary of such entity or to the partners, members, stockholders or affiliates of such entity, or to a charitable or family trust, provided that each donee, transferee or distributee shall sign and deliver a lock-up letter substantially in the form of this letter prior to such transfer and no filing by any party under Section 16(a) of the Exchange Act reporting a reduction in beneficial ownership of shares of Class A Common Stock or securities convertible into or exercisable or exchangeable for

Class A Common Stock shall be required or shall be voluntarily made during the Lock-Up Period in connection with such transfer (other than a filing on a Form 5 made when required and, if the undersigned is a General Atlantic entity, a filing on Form 4 may be made by the undersigned during the Lock-Up Period in connection with a transfer from the undersigned to Steve Denning, Dave Hodgson, Bill Grabe, Bill Ford and Peter Bloom, if the undersigned provides written notice to the Representatives at least three business days prior to such proposed transfer) and such transfer shall not involve a disposition for value. In addition, the undersigned agrees that, without the prior written consent of the Representatives on behalf of the Underwriters, it will not, during the Lock-Up Period, make any demand for or exercise any right with respect to, the registration of any shares of Class A Common Stock or any security convertible into or exercisable or exchangeable for Class A Common Stock or any membership interests of the LLC, except for any such demand or exercise that will not require any filing or other public disclosure to be made in connection therewith until after the expiration of the Lock-Up Period. The undersigned also agrees and consents to the entry of stop transfer instructions with the Company’s and the LLC’s transfer agent and registrar against the transfer of the undersigned’s shares of Class A Common Stock or securities convertible into or exercisable or exchangeable for Class A Common Stock or membership interests of the LLC except in compliance with the foregoing restrictions. Notwithstanding the foregoing, this letter agreement shall not apply to (a) the sale of any Class A Common Stock to the Underwriters pursuant to the Underwriting Agreement, (b) any transfer in connection with, and as contemplated by, the reorganization transactions described in the preliminary prospectus included in the Company’s registration statement at the time of its effectiveness or (c) any exchange of membership units of the LLC and a corresponding number of shares of Class B common stock of the Company for shares of Class A common stock of the Company, or exercise by the Company of its related call right, in each case in a manner consistent with the provisions therefore detailed in the form of the Sixth Amended and Restated Limited Liability Company Agreement of the LLC filed as an exhibit to the registration statement; provided in the case of this clause (c) that no filing under Section 16(a) of the Exchange Act, reporting a change in beneficial ownership of shares of Class A Common Stock or securities convertible into or exercisable or exchangeable for Class A Common Stock, shall be required or shall be voluntarily made during the Lock-Up Period.

If:

(1) during the last 17 days of the Lock-Up Period the Company issues an earnings release or material news or a material event relating to the Company occurs; or

(2) prior to the expiration of the Lock-Up Period, the Company announces that it will release earnings results during the 16-day period beginning on the last day of the Lock-Up Period;

the restrictions imposed by this agreement shall continue to apply until the expiration of the 18-day period beginning on the issuance of the earnings release or the occurrence of the material news or material event.

The undersigned shall not engage in any transaction that may be restricted by this agreement during the 34-day period beginning on the last day of the initial Lock-Up Period unless the undersigned requests and receives prior written confirmation from the Company or the Representatives that the restrictions imposed by this agreement have expired.

The undersigned understands that the Company and the Underwriters are relying upon this agreement in proceeding toward consummation of the Public Offering. The undersigned further understands that this agreement is irrevocable and shall be binding upon the undersigned’s heirs, legal representatives, successors and assigns. This Agreement shall lapse and become null and void if the Public Offering shall not have occurred on or before September 30, 2009 or earlier if the Company has provided written notice to the undersigned that it has determined not to pursue the Public Offering.

This letter is being furnished at the request of the Company in connection with the delivery of our opinion to you of even date herewith (the “Opinion”) under the Underwriting Agreement. Capitalized terms used and not otherwise defined in this letter have the respective meanings given those terms in the Underwriting Agreement.

The Company has filed with the Securities and Exchange Commission (the “Commission”) a Registration Statement on Form S-1 (File No. 333-153451) under the Securities Act of 1933, as amended (the “Act”). The Registration Statement was filed on September 12, 2008, was amended on November 10 , 2008, June 16, 2009 and [ ] , 2009 and, we are advised orally by the Commission, was declared effective by the Commission at [time] on [ ] , 2009. In this letter, the Registration Statement at the time it became effective under the Act, including the information deemed to be part of the Registration Statement under Rule 430A under the Act, is referred to as the “Registration Statement”; the preliminary prospectus included in the Registration Statement immediately prior to the Applicable Time is referred to as the “Pricing Prospectus”; the Pricing Prospectus, taken together with the price of the Shares to the public and the underwriting discount or commission, is referred to as the “Time of Sale Prospectus”; and the prospectus dated [ ], 2009 included as part of the Registration Statement as filed as required by Rule 424(b) under the Act, is referred to as the “Prospectus.”

The primary purpose of our professional engagement was not to establish factual matters or financial, accounting or statistical information. In addition, many

determinations involved in the preparation of the Registration Statement, Pricing Prospectus and the Prospectus are of a wholly or partially non-legal character or relate to legal matters outside the scope of the Opinion. Furthermore, the limitations inherent in the independent verification of factual matters and in the role of outside counsel are such that we have not undertaken to independently verify, and cannot and do not assume responsibility for the accuracy, completeness or fairness of, the statements contained in the Registration Statement, the Pricing Prospectus or the Prospectus (other than as explicitly stated in paragraphs, 6 and 9 of the Opinion).

In the course of acting as special counsel to the Company in connection with the offering of the Shares, we have participated in conferences and telephone conversations with officers and other representatives of the Company and the independent registered public accountants for the Company during which conferences and conversations the contents of the Registration Statement, the Pricing Prospectus, the Prospectus and related matters were discussed. Based upon such participation (and relying as to factual matters on officers, employees and other representatives of the Company and its subsidiaries), our understanding of the U.S. federal securities laws and the experience we have gained in our practice thereunder, we hereby advise you that our work in connection with this matter did not disclose any information that gave us reason to believe that (i) at the time it became effective, the Registration Statement (except for the financial statements, financial statement schedules and other financial data included or omitted therefrom, as to which we express no such belief), included an untrue statement of a material fact or omitted to state a material fact required to be stated therein

or necessary to make the statements therein not misleading; (ii) as of the Applicable Time, the Time of Sale Prospectus (except for the financial statements, financial statement schedules and other financial data included or omitted therefrom,as to which we express no such belief) included an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading or (iii) at the time the Prospectus was issued and at the Closing Date, the Prospectus or any amendment or supplement thereto (except for the financial statements, financial statement schedules and other financial data included or omitted therefrom, as to which we express no such belief) included an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

Our opinion is not based on any independent verification or investigation of the accuracy, completeness or fairness of the statements made or information contained in the Underwriting Agreement, the Time of Sale Prospectus or the Prospectus, except as set forth in paragraph 1 below.

As used herein, the term: (i) “Health Care Laws” means those provisions that pertain to the provision of revenue and payment cycle management to healthcare providers found in statutes, judicial rulings and decrees, and administrative or governmental regulations of the United States of America and the State of Tennessee, including but not limited to the Health Insurance Portability and Accountability Act of 1996; the civil False Claims Act, 31 U.S.C. §§ 3729-3733; the administrative False Claims Act, 42 U.S.C. § 1320a-7b(a); and the American Recovery and Reinvestment Act of 2009; (ii) “Governmental Approval” means any consent, approval, authorization, order, registration or qualification with, any Governmental Authority, other than any consent, approval, authorization, order, registration or qualification which may have become applicable as a result of your involvement in the transactions contemplated by the Underwriting Agreement or because of your legal or regulatory status or because of any other facts specifically pertaining to you; and (iii) “Governmental Authorities” means any court, regulatory body, administrative agency or governmental body of the United States of America or the State of Tennessee.

Based upon and subject to the limitations, qualifications, exceptions and assumptions set forth herein, we are of the opinion that:

1. The statements as to matters of law, if any, made in each of the Time of Sale Prospectus and the Prospectus under the captions “Risk Factors — Risks Related to our Business — Government regulation creates risks and challenges with respect to our compliance efforts and our business strategies” and “Business — Regulation and Legislation” (collectively, the “Specified Prospectus Sections”), insofar as such statements purport to constitute overviews or summaries of the Health Care Laws referred to therein, constitute accurate summaries of the terms of such Health Care Laws in all material respects to the extent of their applicability to the Company.

2. No material Governmental Approval is required under any Health Care Law for the issue and sale of the Shares by the Company.

3. The issue and sale of the Shares by the Company will not result in a breach or violation of any Health Care Law or any order known to us and applicable to the Company issued pursuant to a Health Care Law by a Governmental Authority.

We have not been responsible for the drafting of either the Time of Sale Prospectus or the Prospectus, but have during the course of the preparation of each of the Time of Sale Prospectus and the Prospectus reviewed such documents and conferred with the Company with respect to

We express no opinion herein other than as to the law of the State of Tennessee and the federal laws of the United States.

As used herein, “known to us,” “to our knowledge” and any similar phrase refers solely to the current, actual knowledge, acquired during the course of the representation described in the introductory paragraph of this letter, of those attorneys in this firm who have rendered legal services in connection with such representation (excluding any lawyers whose involvement has been limited to reviewing this opinion as part of our firm’s opinion review procedure).

We have also assumed, without independent investigation that (i) GAPCO Gmbh & Co. KG (“Gmbh”) has all necessary corporate power and authority to execute, deliver and perform its obligations under the Underwriting Agreement, (ii) the execution, delivery and performance of the Underwriting Agreement has been duly authorized by all necessary corporate action by Gmbh and does not violate its organizational documents or the laws of its jurisdiction of organization and (iii) the due execution and delivery of the Underwriting Agreement by Gmbh under the laws of its jurisdiction of organization.

Whenever we indicate that our opinion is based upon our knowledge or words of similar import, our opinion is based solely on the actual knowledge of the attorneys in this firm who are representing the Selling Stockholders in connection with the Underwriting Agreement or who are otherwise responsible for representation of the Selling Stockholders and without any independent verification.

Based on the above, and subject to the stated assumptions, exceptions and qualifications stated below, we are of the opinion that:

1. Each Delaware Selling Stockholder listed on Schedule B to this letter (each, a “Delaware Selling Stockholder”) has all necessary partnership or limited liability company power and authority to execute, deliver and perform its obligations under the Underwriting Agreement and to sell, assign, transfer and deliver the Shares.

2. The Underwriting Agreement has been duly authorized by each Delaware Selling Stockholder and has been duly executed and delivered by or on behalf of each Delaware Selling Stockholder. Assuming the Underwriting Agreement has been

Barclays Capital Inc.

duly authorized, executed and delivered by Gmbh under the laws of Germany, the Underwriting Agreement has been duly executed and delivered by Gmbh (to the extent execution and delivery are governed by the laws of the State of New York).

3. With respect to each Selling Stockholder, the sale of the Shares to be sold by such Selling Stockholder under the Underwriting Agreement and the compliance by such Selling Stockholder with all of the provisions of the Underwriting Agreement with respect to such Shares will not (a) breach or result in a default under any indenture, mortgage, deed of trust, loan agreement or other agreement or instrument known to us to which such Selling Stockholder is a party or by which such Selling Stockholder is bound or to which any of the property or assets of such Selling Stockholder is subject, other than any breaches or defaults that could not reasonably be expected to materially adversely affect such Selling Stockholder’s ability to consummate the transactions contemplated by the Underwriting Agreement, (b) violate in the case of a Delaware Selling Stockholder such Delaware Selling Stockholder’s Entity Documents and (c) violate Applicable Law or any judgment, order or decree of any court or arbitrator known to us, other than any violation that could not reasonably be expected to materially adversely affect such Selling Stockholder’s ability to consummate the transactions contemplated by the Underwriting Agreement. For purposes of this letter, the term “Applicable Law” means the Delaware General Corporation Law (the “GCL”), the Delaware Revised Uniform Limited Partnership Act (the “LPA”) and the Delaware Limited Liability Company Act (the “LLCA”), and those laws, rules and regulations of

the United States of America and the State of New York, in each case which in our experience are normally applicable to the transactions of the type contemplated by the Underwriting Agreement, except that “Applicable Law” does not include the antifraud provisions of the securities laws of any applicable jurisdiction or any state securities or Blue Sky laws of the various States.

4. With respect to each Selling Stockholder, to our knowledge, no consent, approval, authorization or order of, or filing, registration or qualification with, any Governmental Authority, which has not been obtained, taken or made (other than as required by any state securities or Blue Sky laws, as to which we express no opinion) is required under any Applicable Law for the performance by such Selling Stockholder of its obligations under the Underwriting Agreement in connection with the Shares to be sold by such Selling Stockholder thereunder, except for the filings (if any) by the Selling Stockholders with the Securities and Exchange Commission required pursuant to Section 13(d), Section 13(f) or Section 16 of the Securities Exchange Act of 1934, as amended. For purposes of this letter, the term “Governmental Authorities” means any executive, legislative, judicial, administrative or regulatory body of the State of Delaware, New York or the United States of America.

5. Each Selling Stockholder is the record owner of the Shares to be sold by such Selling Stockholder pursuant to the Underwriting Agreement.

6. Assuming each Underwriter acquires its interest in the Shares it has purchased from the Selling Stockholders under the Underwriting Agreement in good

faith without notice of any adverse claim (within the meaning of Section 8-105 of the Uniform Commercial Code in effect in the State of New York in the date of this letter (the “NY-UCC”)) with respect to the Shares, (i) each Underwriter that has purchased the Shares delivered on the date hereof to The Depository Trust Company (assuming The Depository Trust Company is a clearing corporation within the meaning of Section 8-102(a)(5) of the NY-UCC) or other securities intermediary (assuming such other securities intermediary is a securities intermediary within the meaning of Section 8-102(14) of the NY-UCC) by making payment therefor as provided in the Underwriting Agreement, and that has had the Shares credited by book entry to the securities account or accounts (within the meaning of Section 8-501(a) of the NY-UCC, assuming that the securities intermediary’s jurisdiction (within the meaning of Section 8-110(e) of the NY-UCC) for the securities account or accounts is the State of New York) of such Underwriter maintained by The Depository Trust Company or such other securities intermediary will have acquired a security entitlement (within the meaning of Section 8-102(a)(17) of the NY-UCC) to such Shares purchased by such Underwriter, (ii) The Depositary Trust Company or such other securities intermediary shall be a “protected purchaser” of the Shares within the meaning of Section 8-303 of the NY-UCC (assuming that the Depositary Trust Company or such other securities intermediary has no notice of an adverse claim within the meaning of Section 8-105 of the NY-UCC and that the Depositary Trust Company is a clearing corporation within the meaning of Section 8-102(a)(5) of the NY-UCC or such other securities intermediary is a securities

intermediary with the meaning of Section 8-102(14) of the NY-UCC), and (iii) no action based on an adverse claim (within the meaning of Section 8-102(a)(1) and Section 8-502 of the NY-UCC) may be asserted against such Underwriter with respect to such Shares.
