Re: Call Option Transaction

The purpose of this letter agreement (this “Confirmation”) is to confirm the terms and conditions of the call option transaction entered into between [Dealer] (“Dealer”) and Apellis Pharmaceuticals, Inc. (“Counterparty”) as of the Trade Date specified below (the “Transaction”). This letter agreement constitutes a “Confirmation” as referred to in the ISDA Master Agreement specified below. Each party further agrees that this Confirmation together with the Agreement evidence a complete binding agreement between Counterparty and Dealer as to the subject matter and terms of the Transaction to which this Confirmation relates, and shall supersede all prior or contemporaneous written or oral communications with respect thereto.

The definitions and provisions contained in the 2002 ISDA Equity Derivatives Definitions (the “Equity Definitions”), as published by the International Swaps and Derivatives Association, Inc. (“ISDA”) are incorporated into this Confirmation. In the event of any inconsistency between the Equity Definitions and this Confirmation, this Confirmation shall govern. Certain defined terms used herein are based on terms that are defined in the Indenture, dated September 16, 2019, between Counterparty and U.S. Bank National Association, as trustee (the “Indenture”) relating to the 3.500% Convertible Senior Notes due 2026 (the “Convertible Notes” and each USD 1,000 principal amount of Convertible Notes, a “Convertible Note”) issued by Counterparty in an aggregate initial principal amount of USD 520,000,000. In the event of any inconsistency between the terms defined in the Indenture and this Confirmation, this Confirmation shall govern. The parties further acknowledge that the Indenture section numbers used herein are based on the Indenture as executed. Subject to the foregoing, references to the Indenture herein are references to the Indenture on the date of its execution and if the Indenture is amended or supplemented following such date (other than any amendment or supplement (x) pursuant to Section 10.01(h) of the Indenture that, as determined by the Calculation Agent, conforms the Indenture to the description of Convertible Notes in the Offering Memorandum dated September 11, 2019 related to the Convertible Notes (the “Offering Memorandum”) or (y) pursuant to Section 14.07 of the Indenture, subject, in the case of this clause (y), to the second paragraph under “Method of Adjustment” in Section 3), any such amendment or supplement will be disregarded for purposes of this Confirmation (other than as provided in Section 9(i)(iv) below) unless the parties agree otherwise in writing.

Each party is hereby advised, and each such party acknowledges, that the other party has engaged in, or refrained from engaging in, substantial financial transactions and has taken other material actions in reliance upon the parties’ entry into the Transaction to which this Confirmation relates on the terms and conditions set forth below.

1.    This Confirmation evidences a complete and binding agreement between Dealer and Counterparty as to the terms of the Transaction to which this Confirmation relates. This Confirmation shall supplement, form a part of, and be subject to an agreement in the form of the 2002 ISDA Master Agreement (the “Agreement”) as if Dealer and Counterparty had executed an agreement in such form (but without any Schedule except for (i) the election of the laws of the State of New York as the governing law (without reference to choice of law doctrine) on the Trade Date; and (ii) the election that the “Cross Default” provisions of Section 5(a)(vi) of the Agreement will apply to Dealer as if (a) the “Threshold Amount” with respect to Dealer were three percent (3%) of members’ equity of [Dealer] as of the Trade Date, (b) the term “Specified Indebtedness” had the meaning specified in Section 14 of the Agreement, except that such term shall not include obligations in respect of deposits received in the ordinary course of Dealer’s banking business and (c) the following sentence shall be added to the end of Section 5(a)(vi) of the Agreement: “Notwithstanding the foregoing, a default under subsection (2) hereof shall not constitute an Event of Default if (i) the default was caused solely by error or omission of an administrative or operational nature; (ii) funds were available to enable the relevant party to make the payment when due; and (iii) the payment is made within two Local Business Days of such party’s receipt of written notice of its failure to pay.”). In the event of any inconsistency between provisions of the Agreement and this Confirmation, this Confirmation will prevail for the purpose of the

Transaction to which this Confirmation relates. The parties hereby agree that no transaction other than the Transaction to which this Confirmation relates shall be governed by the Agreement and that the Transaction to which this Confirmation relates is not governed by, and shall not be treated as a transaction under, any other ISDA Master Agreement that may exist or be entered into between the parties from time to time.

In no event will the Daily Option Value be less than zero.

Potential Adjustment Events:	Notwithstanding Section 11.2(e) of the Equity Definitions, a “Potential Adjustment Event” means an occurrence of any event or condition, as set forth in any Dilution Adjustment Provision, that would result in an adjustment under the Indenture to the “Conversion Rate” or the composition of a “unit of Reference Property” or to any “Last Reported Sale Price” , “Daily VWAP,” “Daily Conversion Value” or “Daily Settlement Amount” (each as defined in the Indenture). For the avoidance of doubt, Dealer shall not have any delivery or payment obligation hereunder, and no adjustment shall be made to the terms of the Transaction, on account of (x) any distribution of cash, property or securities by Counterparty to holders of the Convertible Notes (upon conversion or otherwise) or (y) any other transaction in which holders of the Convertible Notes are entitled to participate, in each case, in lieu of an adjustment under the Indenture of the type referred to in the immediately preceding sentence (including, without limitation, pursuant to the fourth sentence of Section 14.04(c) of the Indenture or the fourth sentence of Section 14.04(d) of the Indenture.

	Notwithstanding the foregoing and “Consequences of Merger Events / Tender Offers” below:
	(i) if the Calculation Agent in good faith disagrees with any adjustment to the Convertible Notes that involves an exercise of discretion by Counterparty or its board of directors (including, without limitation, pursuant to Section 14.05 of the Indenture, Section 14.07 of the Indenture or any supplemental indenture entered into thereunder or in connection with any proportional adjustment or the determination of the fair value of any securities, property, rights or other assets), then in each such case, the Calculation Agent will determine the adjustment to be made to any one or more of the Strike

9

Price, Number of Options, Option Entitlement and any other variable relevant to the exercise, settlement or payment for the Transaction in a commercially reasonable manner; provided that, notwithstanding the foregoing, if any Potential Adjustment Event occurs during the Settlement Averaging Period but no adjustment was made to any Convertible Note under the Indenture because the relevant Holder (as such term is defined in the Indenture) was deemed to be a record owner of the underlying Shares on the related Conversion Date, then the Calculation Agent shall make an adjustment, as determined by it, to the terms hereof in order to account for such Potential Adjustment Event in a commercially reasonable manner;

(ii)  in connection with any Potential Adjustment Event as a result of an event or condition set forth in Section 14.04(b) of the Indenture or Section 14.04(c) of the Indenture where, in either case, the period for determining “Y” (as such term is used in Section 14.04(b) of the Indenture) or “SP0” (as such term is used in Section 14.04(c) of the Indenture), as the case may be, begins before Counterparty has publicly announced the event or condition giving rise to such Potential Adjustment Event, then the Calculation Agent shall have the right to, in a commercially reasonable manner, adjust any variable relevant to the exercise, settlement or payment for the Transaction as appropriate to reflect the costs (including, but not limited to, hedging mismatches and market losses, assuming that Dealer maintains commercially reasonable hedge positions) and expenses incurred by Dealer in connection with its hedging activities as a result of such event or condition not having been publicly announced prior to the beginning of such period; and

(iii)  if any Potential Adjustment Event is declared and (a) the event or condition giving rise to such Potential Adjustment Event is subsequently amended, modified, cancelled or abandoned, (b) the “Conversion Rate” (as defined in the Indenture) is otherwise not adjusted at the time or in the manner contemplated by the relevant Dilution Adjustment Provision based on such declaration or (c) the “Conversion Rate” (as defined in the Indenture) is adjusted as a result of such Potential Adjustment Event and subsequently re-adjusted (each of clauses (a), (b) and (c), a “Potential Adjustment Event Change”) then, in each case, the Calculation Agent shall have the right to, in a commercially

10

	reasonable manner, adjust any variable relevant to the exercise, settlement or payment for the Transaction as appropriate to reflect the costs (including, but not limited to, hedging mismatches and market losses, assuming that Dealer maintains commercially reasonable hedge positions) and expenses incurred by Dealer in connection with its hedging activities as a result of such Potential Adjustment Event Change.
Dilution Adjustment Provisions:	Sections 14.04(a), (b), (c), (d) and (e) and Section 14.05 of the Indenture.
Extraordinary Events applicable to the Transaction:
Merger Events:	Applicable; provided that notwithstanding Section 12.1(b) of the Equity Definitions, a “Merger Event” means the occurrence of any event or condition set forth in the definition of “Merger Event” in Section 14.07(a) of the Indenture.
Tender Offers:	Applicable; provided that notwithstanding Section 12.1(d) of the Equity Definitions, a “Tender Offer” means the occurrence of any event or condition set forth in Section 14.04(e) of the Indenture.
Consequences of Merger Events/
Tender Offers:	Notwithstanding Section 12.2 and Section 12.3 of the Equity Definitions, upon the occurrence of a Merger Event or a Tender Offer, the Calculation Agent shall make a corresponding adjustment in respect of any adjustment under the Indenture to any one or more of the nature of the Shares (in the case of a Merger Event), Strike Price, Number of Options, Option Entitlement and any other variable relevant to the exercise, settlement or payment for the Transaction, subject to the second paragraph under “Method of Adjustment” to the extent an analogous adjustment is required to be made pursuant to the Indenture in respect of such Merger Event or Tender Offer; provided, however, that such adjustment shall be made without regard to any adjustment to the Conversion Rate pursuant to any Excluded Provision; provided further that if, with respect to a Merger Event or a Tender Offer, (i) the consideration for the Shares includes (or, at the option of a holder of Shares, may include) shares of an entity or person that is not a corporation or is not organized under the laws of the United States, any State thereof or the District of Columbia or (ii) the Counterparty to the Transaction following such Merger Event or Tender Offer will not be a corporation organized under the laws of the United States, any State thereof or the District of Columbia, then, in either case, Cancellation and Payment (Calculation Agent Determination) may apply at Dealer’s sole election; provided further that, for the avoidance of doubt, adjustments shall be made pursuant to the provisions set forth above regardless of whether any Merger Event or Tender Offer gives rise to an Early Conversion.

An Announcement Event shall be an “Extraordinary Event” for purposes of the Equity Definitions, to which Article 12 of the Equity Definitions is applicable.

For the avoidance of doubt, the occurrence of an Announcement Event with respect to

12

	any transaction or intention shall not preclude the occurrence of a later Announcement Event with respect to such transaction or intention. For purposes of this definition of “Announcement Event,” (A) “Merger Event” shall mean such term as defined under Section 12.1(b) of the Equity Definitions (but, for the avoidance of doubt, the remainder of the definition of “Merger Event” in Section 12.1(b) of the Equity Definitions following the definition of “Reverse Merger” therein shall be disregarded) and (B) “Tender Offer” shall mean such term as defined under Section 12.1(d) of the Equity Definitions; provided that Section 12.1(d) of the Equity Definitions is hereby amended by replacing “10%” with “20%” in the third line thereof.

Nationalization, Insolvency or Delisting:	Cancellation and Payment (Calculation Agent Determination); provided that, in addition to the provisions of Section 12.6(a)(iii) of the Equity Definitions, it will also constitute a Delisting if the Exchange is located in the United States and the Shares are not immediately re-listed, re-traded or re-quoted on any of the New York Stock Exchange, The Nasdaq Global Select Market or The Nasdaq Global Market (or their respective successors); if the Shares are immediately re-listed, re-traded or re-quoted on any of the New York Stock Exchange, The Nasdaq Global Select Market or The Nasdaq Global Market (or their respective successors), such exchange or quotation system shall thereafter be deemed to be the Exchange.
Additional Disruption Events:
Change in Law:	Applicable; provided that Section 12.9(a)(ii) of the Equity Definitions is hereby amended by (i) replacing the phrase “the interpretation” in the third line thereof with the phrase “, or non-confidential announcement of, the formal or informal interpretation”, (ii) replacing the word “Shares” where it appears in clause (X) thereof with the words “Hedge Position”, (iii) replacing the parenthetical beginning after the word “regulation” in the second line thereof the words “(including, for the avoidance of doubt and without limitation, (x) any tax law or (y) adoption, effectiveness or promulgation of new regulations authorized or mandated by existing statute)” and (iv) adding the words “provided that, in the case of clause (Y)

13

(i) Counterparty understands that no obligations of Dealer to it hereunder will be entitled to the benefit of deposit insurance and that such obligations will not be guaranteed by any Affiliate of Dealer or any governmental agency.

9.    Other Provisions.

(a) Opinions. Counterparty shall deliver to Dealer an opinion of counsel, dated as of the Trade Date, with respect to the matters set forth in Sections 8(a) through (c) of this Confirmation; provided that any such opinion of counsel may contain customary exceptions and qualifications, including, without limitation, exceptions and qualifications relating to indemnification provisions; Delivery of such opinion to Dealer shall be a condition precedent for the purpose of Section 2(a)(iii) of the Agreement with respect to each obligation of Dealer under Section 2(a)(i) of the Agreement.

(b) Repurchase Notices. Counterparty shall, on any day on which Counterparty effects any repurchase of Shares, promptly give Dealer a written notice of such repurchase (a “Repurchase Notice”) on such day if following such repurchase, the number of outstanding Shares as determined on such day is (i) less than 71.4 million (in the case of the first such notice) or (ii) thereafter more than 3.7 million less than the number of Shares included in the immediately preceding Repurchase Notice. Counterparty agrees to indemnify and hold harmless Dealer and its affiliates and their respective officers, directors, employees, affiliates, advisors, agents and controlling persons (each, an “Indemnified Person”) from and against any and all reasonable losses (including losses relating to Dealer’s commercially reasonable hedging activities as a consequence of becoming, or of the risk of becoming, a Section 16 “insider”, including without limitation, any forbearance from commercially reasonable hedging activities or cessation of commercially reasonable hedging activities and any reasonable losses in connection therewith with respect to the Transaction), claims, damages, judgments, liabilities and reasonable expenses (including reasonable attorney’s fees), joint or several, which an Indemnified Person may become subject to under applicable securities laws, as a result of Counterparty’s failure to provide Dealer with a Repurchase Notice on the day and in the manner specified in this paragraph, and to reimburse, within 30 days, upon written request, each of such Indemnified Persons for any reasonable legal or other expenses incurred in connection with investigating, preparing for, providing testimony or other evidence in connection with or defending any of the foregoing. If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against the Indemnified Person as a result of Counterparty’s failure to provide Dealer with a Repurchase Notice in accordance with this paragraph, such Indemnified Person shall promptly notify Counterparty in writing, and Counterparty, upon request of the Indemnified Person, shall retain counsel reasonably satisfactory to the Indemnified Person to represent the Indemnified Person and any others Counterparty may designate in such proceeding and shall pay the reasonable fees and expenses of such counsel related to such proceeding. Counterparty shall not be liable for any settlement of any proceeding contemplated by this paragraph that is effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, Counterparty agrees to indemnify any Indemnified Person from and against any loss or liability by reason of such settlement or judgment. Counterparty shall not, without the prior written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding contemplated by this paragraph that is in respect of which any Indemnified Person is or could have been a party and indemnity could have been sought hereunder by such Indemnified Person, unless such settlement includes an unconditional release of such Indemnified Person from all liability on claims that are the subject matter of such proceeding on terms reasonably satisfactory to such Indemnified Person. Counterparty shall not be liable for any losses, claims, damages or liabilities (or expenses relating thereto) of any Indemnified Person that result from the bad faith, gross negligence, willful misconduct or fraud of such Indemnified Person. If the indemnification provided for in this paragraph is unavailable to an Indemnified Person or insufficient in respect of any reasonable losses, claims, damages or liabilities referred to therein, then Counterparty hereunder, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities. The remedies provided for in this paragraph (b) are not exclusive and shall not limit any rights or remedies which may otherwise be available to any Indemnified Person at law or in equity. The indemnity and contribution agreements contained in this paragraph shall remain operative and in full force and effect regardless of the termination of the Transaction.

18

(c) Regulation M. Counterparty is not on the Trade Date engaged in a distribution, as such term is used in Regulation M under the Exchange Act, of any securities of Counterparty, other than a distribution meeting the requirements of the exception set forth in Rules 101(b)(10) and 102(b)(7) of Regulation M. Counterparty shall not, until the second Scheduled Trading Day immediately following the Effective Date, engage in any such distribution.

(d) No Manipulation. Counterparty is not entering into the Transaction to create actual or apparent trading activity in the Shares (or any security convertible into or exchangeable for the Shares) or to raise or depress or otherwise manipulate the price of the Shares (or any security convertible into or exchangeable for the Shares) or otherwise in violation of the Exchange Act.

(e) Transfer or Assignment.

(i) Counterparty shall have the right to transfer or assign its rights and obligations hereunder with respect to all, but not less than all, of the Options hereunder (such Options, the “Transfer Options”); provided that such transfer or assignment shall be subject to reasonable conditions that Dealer may impose, including but not limited, to the following conditions:

(A) With respect to any Transfer Options, Counterparty shall not be released from its notice and indemnification obligations pursuant to Section 9(b) or any obligations under Section 9(n) or 9(s) of this Confirmation;

(B) Any Transfer Options shall only be transferred or assigned to a third party that is a United States person (as defined in the Internal Revenue Code of 1986, as amended);

(C) Such transfer or assignment shall be effected on terms, including any reasonable undertakings by such third party (including, but not limited to, an undertaking with respect to compliance with applicable securities laws in a manner that, in the reasonable judgment of Dealer, will not expose Dealer to material risks under applicable securities laws) and execution of any documentation and delivery of legal opinions with respect to securities laws and other matters by such third party and Counterparty, as are requested and reasonably satisfactory to Dealer;

(D) Dealer will not, as a result of such transfer and assignment, be required to pay the transferee on any payment date an amount under Section 2(d)(i)(4) of the Agreement greater than an amount that Dealer would have been required to pay to Counterparty in the absence of such transfer and assignment;

(E) An Event of Default, Potential Event of Default or Termination Event will not occur as a result of such transfer and assignment;

(F) Without limiting the generality of clause (B), Counterparty shall cause the transferee to make such Payee Tax Representations and to provide such tax documentation as may be reasonably requested by Dealer to permit Dealer to determine that results described in clauses (D) and (E) will not occur upon or after such transfer and assignment; and

(G) Counterparty shall be responsible for all reasonable costs and expenses, including reasonable counsel fees, incurred by Dealer in connection with such transfer or assignment.

(ii) Dealer may, without Counterparty’s consent, transfer or assign all or any part of its rights or obligations under the Transaction (A) to any affiliate of Dealer (1) that has a long-term issuer rating that is equal to or better than Dealer’s credit rating at the time of such

19

transfer or assignment, or (2) whose obligations hereunder will be guaranteed, pursuant to the terms of a customary guarantee in a form used by Dealer generally for similar transactions, by [Dealer], or (B) to any other third party with a long-term issuer rating equal to or better than the lesser of (1) the credit rating of Dealer at the time of the transfer and (2) A- by Standard and Poor’s Rating Group, Inc. or its successor (“S&P”), or A3 by Moody’s Investor Service, Inc. (“Moody’s”) or, if either S&P or Moody’s ceases to provide such long-term issuer rating, at least an equivalent rating or better by a substitute rating agency mutually agreed by Counterparty and Dealer; provided that either (x) the transferee in any such transfer should be a “dealer in securities” within the meaning of Section 475(c)(1) of the Internal Revenue Code of 1986, as amended (the “Code”) or (y) the transfer will not result in a deemed exchange within the meaning of Section 1001 of the Code. If at any time at which (A) the Section 16 Percentage exceeds 8%, (B) the Option Equity Percentage exceeds 14.5%, or (C) the Share Amount exceeds the Applicable Share Limit (if any applies) (any such condition described in clauses (A), (B) or (C), an “Excess Ownership Position”), Dealer is unable after using its commercially reasonable efforts to effect a transfer or assignment of Options to a third party on pricing terms reasonably acceptable to Dealer and within a time period reasonably acceptable to Dealer such that no Excess Ownership Position exists, then Dealer may designate any Exchange Business Day as an Early Termination Date with respect to a portion of the Transaction (the “Terminated Portion”), such that following such partial termination no Excess Ownership Position exists. In the event that Dealer so designates an Early Termination Date with respect to a portion of the Transaction, a payment shall be made pursuant to Section 6 of the Agreement as if (1) an Early Termination Date had been designated in respect of a Transaction having terms identical to the Transaction and a Number of Options equal to the number of Options underlying the Terminated Portion, (2) Counterparty were the sole Affected Party with respect to such partial termination and (3) the Terminated Portion were the sole Affected Transaction (and, for the avoidance of doubt, the provisions of Section 9(l) shall apply to any amount that is payable by Dealer to Counterparty pursuant to this sentence as if Counterparty was not the Affected Party); provided that in calculating any amount due following such designation, Dealer shall act in good faith and in a commercially reasonable manner and upon written request from Counterparty, Dealer will, as soon as reasonably practicable, provide to Counterparty a statement displaying in reasonable detail the basis for such calculation (it being understood that Dealer shall not be obligated to disclose any proprietary models or confidential data or information or any proprietary or confidential models used by it in making such determination or calculation or any information that is subject to an obligation not to disclose such information). The “Section 16 Percentage” as of any day is the fraction, expressed as a percentage, (A) the numerator of which is the number of Shares that Dealer and any of its affiliates or any other person subject to aggregation with Dealer for purposes of the “beneficial ownership” test under Section 13 of the Exchange Act, or any “group” (within the meaning of Section 13 of the Exchange Act) of which Dealer is or may be deemed to be a part beneficially owns (within the meaning of Section 13 of the Exchange Act), without duplication, on such day (or, to the extent that for any reason the equivalent calculation under Section 16 of the Exchange Act and the rules and regulations thereunder results in a higher number, such higher number) and (B) the denominator of which is the number of Shares outstanding on such day. The “Option Equity Percentage” as of any day is the fraction, expressed as a percentage, (A) the numerator of which is the sum of (1) the product of the Number of Options and the Option Entitlement and (2) the aggregate number of Shares underlying any other call option transaction sold by Dealer to Counterparty, and (B) the denominator of which is the number of Shares outstanding. The “Share Amount” as of any day is the number of Shares that Dealer and any person whose ownership position would be aggregated with that of Dealer (Dealer or any such person, a “Dealer Person”) under any law, rule, regulation, regulatory order or organizational documents or contracts of Counterparty that are, in each case, applicable

20

to ownership of Shares (“Applicable Restrictions”), owns, beneficially owns, constructively owns, controls, holds the power to vote or otherwise meets a relevant definition of ownership under any Applicable Restriction, as determined by Dealer in its reasonable discretion. The “Applicable Share Limit” means a number of Shares equal to (A) the minimum number of Shares that could give rise to reporting or registration obligations (except for any filings on Form 13F, Schedule 13D or Schedule 13G under the Exchange Act, in each case as in effect on the Trade Date) or other requirements (including obtaining prior approval from any person or entity) of a Dealer Person, or could result in an adverse effect on a Dealer Person, under any Applicable Restriction, as determined by Dealer in its reasonable discretion, minus (B) 1% of the number of Shares outstanding.

(iii) Notwithstanding any other provision in this Confirmation to the contrary requiring or allowing Dealer to purchase, sell, receive or deliver any Shares or other securities, or make or receive any payment in cash, to or from Counterparty, Dealer may designate any of its affiliates to purchase, sell, receive or deliver such Shares or other securities, or to make or receive such payment in cash, and otherwise to perform Dealer’s obligations in respect of the Transaction and any such designee may assume such obligations. Dealer shall be discharged of its obligations to Counterparty to the extent of any such performance.

(f) Staggered Settlement. If upon advice of counsel with respect to applicable legal and regulatory requirements, including any requirements relating to Dealer’s commercially reasonable hedging activities hereunder, Dealer reasonably determines that it would not be practicable or advisable to deliver, or to acquire Shares to deliver, any or all of the Shares to be delivered by Dealer on any Settlement Date for the Transaction, Dealer may, by notice to Counterparty on or prior to any Settlement Date (a “Nominal Settlement Date”), elect to deliver the Shares on two or more dates (each, a “Staggered Settlement Date”) as follows:

(i) in such notice, Dealer will specify to Counterparty the related Staggered Settlement Dates (each of which shall be on or prior to such Nominal Settlement Date) and the number of Shares that it will deliver on each Staggered Settlement Date;

(ii) the aggregate number of Shares that Dealer will deliver to Counterparty hereunder on all such Staggered Settlement Dates will equal the number of Shares that Dealer would otherwise be required to deliver on such Nominal Settlement Date; and

(iii) if the Net Share Settlement terms or the Combination Settlement terms set forth above were to apply on the Nominal Settlement Date, then the Net Share Settlement terms or the Combination Settlement terms, as the case may be, will apply on each Staggered Settlement Date, except that the Shares otherwise deliverable on such Nominal Settlement Date will be allocated among such Staggered Settlement Dates as specified by Dealer in the notice referred to in clause (i) above; and

(iv) when specifying Staggered Settlement Dates pursuant to this Section 9(j), Dealer shall specify the fewest number of Staggered Settlement Dates as is reasonably practicable or advisable under the circumstances in the sole discretion of Dealer.

(g) Reserved.

(h) Reserved.

(i) Additional Termination Events.

(i) Within three Scheduled Trading Days following any Repayment Event (as defined below), Counterparty may notify Dealer of such Repayment Event and the details thereof, including the aggregate principal amount of Convertible Notes (including the aggregate

21

principal amount thereof, if any, that are Subject Convertible Notes (as defined below)) subject to such Repayment Event (any such notice, a “Repayment Notice”); provided that, unless such Repayment Event relates solely to Subject Convertible Notes, the Repayment Notice delivered to Dealer shall specify the aggregate principal amount of the Convertible Notes subject to a Repayment Event (as defined in the Base Call Option Confirmations) under the Base Call Option Confirmations. Any Repayment Notice shall contain a written representation by Counterparty to Dealer that Counterparty is not, on the date of such Repayment Notice, in possession of any material non-public information with respect to Counterparty or the Shares. The receipt by Dealer from Counterparty of any Repayment Notice shall constitute an Additional Termination Event as provided in this Section 9(i)(i). Upon receipt of any such Repayment Notice, Dealer shall designate an Exchange Business Day following receipt of such Repayment Notice as an Early Termination Date with respect to the portion of the Transaction corresponding to a number of Options (the “Repayment Options”) equal to the lesser of (A) (I) the aggregate principal amount of Subject Convertible Notes specified in such Repayment Notice, divided by USD 1,000, plus (II) in the case of any Convertible Notes specified in such Repayment Notice that are not Subject Convertible Notes, the excess, if any, of (x) the aggregate principal amount of such other Convertible Notes specified in such Repayment Notice, divided by USD 1,000 over (y) the number of “Repayment Options” (as defined in the Base Call Option Confirmations), if any, that relate to such Convertible Notes (and for purposes of determining whether any Options under this Confirmation or under the Base Call Option Confirmations will be among the Repayment Options hereunder or under, and as defined in, the Base Call Option Confirmations, all Subject Convertible Notes specified in any Repayment Notice shall be allocated to Options under this Confirmation and all other Convertible Notes specified in any Repayment Notice shall be allocated first to the Base Call Option Confirmations until all Options thereunder are exercised or terminated), and (B) the Number of Options as of the date Dealer designates such Early Termination Date and, as of such date, the Number of Options shall be reduced by the number of Repayment Options. Any payment hereunder with respect to such termination (the “Repayment Unwind Payment”) shall be calculated pursuant to Section 6 of the Agreement as if (1) an Early Termination Date had been designated in respect of a Transaction having terms identical to the Transaction and a Number of Options equal to the number of Repayment Options, (2) Counterparty were the sole Affected Party with respect to such Additional Termination Event and (3) the terminated portion of the Transaction were the sole Affected Transaction. “Repayment Event” means that (i) any Convertible Notes are repurchased or redeemed (whether pursuant to Section 15.02 or Section 16.01 of the Indenture or for any other reason) by Counterparty or any of its subsidiaries, (ii) any Convertible Notes are delivered to Counterparty or any of its subsidiaries in exchange for delivery of any property or assets of such party (howsoever described), (iii) any principal of any of the Convertible Notes is repaid prior to the final maturity date of the Convertible Notes, (iv) any Convertible Notes are exchanged by or for the benefit of the Holders (as such term is defined in the Indenture) thereof for any other securities of Counterparty or any of its subsidiaries (or any other property, or any combination thereof) pursuant to any exchange offer or similar transaction, or (v) any Convertible Notes cease to be outstanding for any other reason (except as a result of conversion). For the avoidance of doubt, any conversion of Convertible Notes (whether into cash, Shares, “Reference Property” (as defined in the Indenture) or any combination thereof) pursuant to the terms of the Indenture shall not constitute a Repayment Event. “Subject Convertible Notes” means Convertible Notes with the CUSIP No. 03753U AC0.

22

(ii) Notwithstanding anything to the contrary in this Confirmation, upon any Early Conversion in respect of which a Notice of Conversion that is effective as to Counterparty has been delivered by the relevant converting Holder:

(A) Counterparty shall, within three Scheduled Trading Days of the Conversion Date for such Early Conversion, provide written notice (an “Early Conversion Notice”) to Dealer specifying the number of Convertible Notes (and the portion thereof that are Subject Convertible Notes) surrendered for conversion on such Conversion Date (such Convertible Notes, the “Affected Convertible Notes”), the number of Affected Convertible Notes (as defined in the Base Call Option Confirmations), if any, and the giving of such Early Conversion Notice shall constitute an Additional Termination Event as provided in this clause (ii); provided that no Early Conversion Notice shall be required to the extent none of the Affected Convertible Notes are Subject Convertible Notes and the number of Options under the Base Call Option Confirmations are sufficient to cover the number of Convertible Notes so surrendered for conversion;

(B) upon receipt of any such Early Conversion Notice, Dealer shall designate an Exchange Business Day as an Early Termination Date (which Exchange Business Day shall be no earlier than one Scheduled Trading Day following the Conversion Date for such Early Conversion) with respect to the portion of the Transaction corresponding to a number of Options (the “Affected Number of Options”) equal to the lesser of (x) (I) the number of Affected Convertible Notes that are Subject Convertible Notes plus (II) in the case of any other Affected Convertible Notes, the excess of the number of such Affected Convertible Notes over the “Affected Number of Options” (as defined in the Base Call Option Confirmations), if any, that relate to such Affected Convertible Notes as specified in the applicable Early Conversion Notice and (y) the Number of Options as of the Conversion Date for such Early Conversion;

(C) any payment hereunder with respect to such termination shall be calculated pursuant to Section 6 of the Agreement as if (x) an Early Termination Date had been designated in respect of a Transaction having terms identical to the Transaction and a Number of Options equal to the Affected Number of Options, (y) Counterparty were the sole Affected Party with respect to such Additional Termination Event and (z) the terminated portion of the Transaction were the sole Affected Transaction; provided that the amount payable with respect to such termination shall not be greater than (1) the Applicable Percentage multiplied by (2) the Affected Number of Options, multiplied by (3) (x) the sum of (i) the amount of cash paid (if any) to the Holder (as such term is defined in the Indenture) of an Affected Convertible Note upon conversion of such Affected Convertible Note and (ii) the number of Shares delivered (if any) to the Holder (as such term is defined in the Indenture) of an Affected Convertible Note upon conversion of such Affected Convertible Note, multiplied by the Applicable Limit Price of one Share, minus (y) USD 1,000;

(D) for the avoidance of doubt, in determining the amount payable in respect of such Affected Transaction pursuant to Section 6 of the Agreement, the Calculation Agent shall assume that (x) the relevant Early Conversion and any conversions, adjustments, agreements, payments, deliveries or acquisitions by or on behalf of Counterparty leading thereto had not occurred, (y) no adjustments to the Conversion Rate have occurred pursuant to any Excluded Provision and (z) the corresponding Convertible Notes remain outstanding; and

(E) the Transaction shall remain in full force and effect, except that, as of the Conversion Date for such Early Conversion, the Number of Options shall be reduced by the Affected Number of Options.

23

(iii) Notwithstanding anything to the contrary in this Confirmation if an event of default with respect to Counterparty occurs under the terms of the Convertible Notes as set forth in Section 6.01 of the Indenture that results in an acceleration of the Convertible Notes under the terms of the Indenture, then such event of default shall constitute an Additional Termination Event applicable to the Transaction and, with respect to such Additional Termination Event, (A) Counterparty shall be deemed to be the sole Affected Party, (B) the Transaction shall be the sole Affected Transaction and (C) Dealer shall be the party entitled to designate an Early Termination Date pursuant to Section 6(b) of the Agreement.

(iv) Notwithstanding anything to the contrary in this Confirmation, the occurrence of an Amendment Event shall constitute an Additional Termination Event applicable to the Transaction and, with respect to such Additional Termination Event, (A) Counterparty shall be deemed to be the sole Affected Party, (B) the Transaction shall be the sole Affected Transaction and (C) Dealer shall be the party entitled to designate an Early Termination Date pursuant to Section 6(b) of the Agreement. “Amendment Event” means that Counterparty amends, modifies, supplements, waives or obtains a waiver in respect of any term of the Indenture or the Convertible Notes governing the principal amount, coupon, maturity, repurchase obligation of Counterparty, redemption right of Counterparty, any term relating to conversion of the Convertible Notes (including changes to the conversion rate, conversion rate adjustment provisions, conversion settlement dates or conversion conditions), or any term that would require consent of the holders of not less than 100% of the principal amount of the Convertible Notes to amend (other than, in each case, any amendment or supplement (v) pursuant to Section 10.01(h) of the Indenture that, as determined by the Calculation Agent, conforms the Indenture to the description of Convertible Notes in the Offering Memorandum, (w) pursuant to Section 14.07 of the Indenture, (x) pursuant to Section 10.01(c) of the Indenture, (y) pursuant to Section 10.01(l) of the Indenture or (z) pursuant to Section 10.01(a) of the Indenture that, as determined by Calculation Agent, cures any ambiguity, defect or inconsistency in the Indenture or in the Convertible Notes in a manner that does not adversely affect any holder of the Convertible Notes in any material respect), in each case, without the consent of Dealer.

(j) Amendments to Equity Definitions.

(i) Section 11.2(e)(vii) of the Equity Definitions is hereby amended by deleting the words “that may have a diluting or concentrative effect on the theoretical value of the relevant Shares” and replacing them with the words “that is the result of a corporate event involving the Issuer or its securities that has a material economic effect on the Shares or options on the Shares; provided that such event is not based on (a) an observable market, other than the market for the Company’s own stock or (b) an observable index, other than an index calculated and measured solely by reference to Company’s own operations.”;

(ii) Section 12.6(a)(ii) of the Equity Definitions is hereby amended by (1) inserting “(1) immediately following the word “means” in the first line thereof and (2) inserting immediately prior to the semi-colon at the end of subsection (B) thereof the following words: “or (2) the occurrence of any of the events specified in Section 5(a)(vii)(1) through (9) of the ISDA Master Agreement with respect to that Issuer”;

(k) Setoff. Obligations under the Transaction shall not be set off by either party against any other obligations of the parties, whether arising under the Agreement, this Confirmation, under any other agreement between the parties hereto, by operation of law or otherwise.

(l) Alternative Calculations and Payment on Early Termination and on Certain Extraordinary Events. If (a) an Early Termination Date (whether as a result of an Event of Default or a Termination Event) occurs or is designated with respect to the Transaction or (b) the Transaction is cancelled or terminated upon the occurrence of an Extraordinary Event (except as a result of (i) a Nationalization, Insolvency or Merger Event in which the consideration to be paid to holders of Shares consists solely of cash, (ii) an Announcement Event, a Merger Event or Tender Offer that is within Counterparty’s control, or (iii) an Event of Default in which Counterparty is the Defaulting Party or a Termination Event in which Counterparty is the Affected Party other than an Event of Default of the type described in Section 5(a)(iii), (v), (vi), (vii) or (viii) of the Agreement or a Termination Event of the type described in Section 5(b) of the Agreement, in each case that resulted from an event or events outside Counterparty’s control), and if Dealer would owe any amount to Counterparty pursuant to Section 6(d)(ii) of the Agreement or any Cancellation Amount pursuant to Article 12 of the Equity Definitions (any such amount, a “Payment Obligation”), then Dealer shall satisfy the Payment Obligation by the Share Termination Alternative (as defined below), unless (a) Counterparty gives irrevocable telephonic notice to Dealer, confirmed in writing within one Scheduled Trading Day, no later than 12:00 p.m. (New York City time) on the date of the Announcement Event, Merger Date, Tender Offer Date, Announcement Date (in the case of a Nationalization, Insolvency or Delisting), Early Termination Date or date of cancellation, as applicable, of its election that the Share Termination Alternative shall not apply, (b) Counterparty remakes the representation set forth in Section 8(f) as of the date of such election and (c) Dealer agrees, in good faith and in its commercially reasonable discretion, to such election, in which case the provisions of Section 12.7 or Section 12.9 of the Equity Definitions, or the provisions of Section 6(d)(ii) of the Agreement, as the case may be, shall apply.

Share Termination Alternative:	If applicable, Dealer shall deliver to Counterparty the Share Termination Delivery Property on, or within a commercially reasonable period of time after, the date when the relevant Payment Obligation would otherwise be due pursuant to Section 12.7 or 12.9 of the Equity Definitions or Section 6(d)(ii) and 6(e) of the Agreement, as applicable, in satisfaction of such Payment Obligation in the manner reasonably requested by Counterparty free of payment.
Share Termination Delivery Property:	A number of Share Termination Delivery Units, as calculated by the Calculation Agent, equal to the Payment Obligation divided by the Share Termination Unit Price. The Calculation Agent shall adjust the Share Termination Delivery Property by replacing any fractional portion of a security therein with an amount of cash equal to the value of such fractional security based on the values used to calculate the Share Termination Unit Price.
Share Termination Unit Price:	The value to Dealer of property contained in one Share Termination Delivery Unit, as determined by the Calculation Agent in its discretion by commercially reasonable means and notified by the Calculation Agent to Dealer at the time of notification of the Payment Obligation. For the avoidance of doubt, the parties agree that in determining the Share Termination Delivery Unit

25

	Price the Calculation Agent may consider the purchase price paid in connection with the purchase of Share Termination Delivery Property, to the extent doing so is a commercially reasonable approximation of fair value.
Share Termination Delivery Unit:	One Share or, if the Shares have changed into cash or any other property or the right to receive cash or any other property as the result of a Nationalization, Insolvency or Merger Event (any such cash or other property, the “Exchange Property”), a unit consisting of the type and amount of such Exchange Property received by a holder of one Share (without consideration of any requirement to pay cash or other consideration in lieu of fractional amounts of any securities) in such Nationalization, Insolvency or Merger Event, as determined by the Calculation Agent.
Failure to Deliver:	Applicable
Other applicable provisions:	If Share Termination Alternative is applicable, the provisions of Sections 9.8, 9.9 and 9.11 (as modified above) of the Equity Definitions and the provisions set forth opposite the caption “Representation and Agreement” in Section 2 will be applicable, except that all references in such provisions to “Physically-settled” shall be read as references to “Share Termination Settled” and all references to “Shares” shall be read as references to “Share Termination Delivery Units”. “Share Termination Settled” in relation to the Transaction means that Share Termination Alternative is applicable to the Transaction.

(m) Waiver of Jury Trial. Each party waives, to the fullest extent permitted by applicable law, any right it may have to a trial by jury in respect of any suit, action or proceeding relating to the Transaction. Each party (i) certifies that no representative, agent or attorney of either party has represented, expressly or otherwise, that such other party would not, in the event of such a suit, action or proceeding, seek to enforce the foregoing waiver and (ii) acknowledges that it and the other party have been induced to enter into the Transaction, as applicable, by, among other things, the mutual waivers and certifications provided herein.

(n) Registration. Counterparty hereby agrees that if, in the good faith reasonable judgment of Dealer based on the advice of counsel, the Shares or other Hedge Positions (the “Hedge Shares”) acquired by Dealer for the purpose of hedging its obligations pursuant to the Transaction cannot be sold in the public market by Dealer without registration under the Securities Act, Counterparty shall, at its election, either (i) in order to allow Dealer to sell the Hedge Shares in a registered offering, make available to Dealer an effective registration statement under the Securities Act and enter into an agreement, in form and substance reasonably satisfactory to Dealer, substantially in the form of an underwriting agreement customary for a registered secondary offering of a similar size; provided, however, that if Dealer, in its sole reasonable discretion, is not satisfied with access to due diligence materials, the results of its due diligence investigation, or the procedures and documentation for the registered offering referred to above, then clause (ii) or clause (iii) of this paragraph shall apply at the election of Counterparty, (ii) in order to allow Dealer to sell the Hedge Shares in a private placement, enter into a private placement agreement substantially similar to

26

private placement purchase agreements customary for private placements of equity securities of a similar size, in form and substance commercially reasonably satisfactory to Dealer (in which case, the Calculation Agent shall make any adjustments to the terms of the Transaction that are necessary, in its reasonable judgment, to compensate Dealer for any discount from the public market price of the Shares incurred on the sale of Hedge Shares in a private placement), or (iii) purchase the Hedge Shares from Dealer at the then-current market price on such Exchange Business Days, and in the amounts and at such time(s), reasonably requested by Dealer.

(o) Tax Disclosure. Effective from the date of commencement of discussions concerning the Transaction, Counterparty and each of its employees, representatives, or other agents may disclose to any and all persons, without limitation of any kind, the tax treatment and tax structure of the Transaction and all materials of any kind (including opinions or other tax analyses) that are provided to Counterparty relating to such tax treatment and tax structure.

(p) Right to Extend. Dealer may postpone or add, in whole or in part, any Valid Day or Valid Days during the Settlement Averaging Period or any other date of valuation, payment or delivery by Dealer, with respect to some or all of the Options hereunder, if Dealer reasonably and in good faith determines that such action is reasonably necessary or appropriate to (i) preserve Dealer’s commercially reasonable hedging or hedge unwind activity hereunder in light of existing liquidity conditions or (ii) based on advice of counsel, to enable Dealer to effect purchases of Shares or other Hedge Positions in connection with its commercially reasonable hedging, hedge unwind or settlement activity hereunder in a manner that would, if Dealer were Counterparty or an affiliated purchaser of Counterparty, be in compliance with applicable legal, regulatory or self-regulatory requirements, or with related policies and procedures applicable to Dealer; provided that no such Valid Day or other date of valuation, payment or delivery may be postponed or added more than 100 Valid Days after the original Valid Day or other date of valuation, payment or delivery, as the case may be.

(q) Status of Claims in Bankruptcy. Dealer acknowledges and agrees that this Confirmation is not intended to convey to Dealer rights against Counterparty with respect to the Transaction that are senior to the claims of common stockholders of Counterparty in any United States bankruptcy proceedings of Counterparty; provided that nothing herein shall limit or shall be deemed to limit Dealer’s right to pursue remedies in the event of a breach by Counterparty of its obligations and agreements with respect to the Transaction; provided, further that nothing herein shall limit or shall be deemed to limit Dealer’s rights in respect of any transactions other than the Transaction.

(r) Securities Contract; Swap Agreement. The parties hereto intend for (i) the Transaction to be a “securities contract” and a “swap agreement” as defined in the Bankruptcy Code (Title 11 of the United States Code) (the “Bankruptcy Code”), and the parties hereto to be entitled to the protections afforded by, among other Sections, Sections 362(b)(6), 362(b)(17), 546(e), 546(g), 555 and 560 of the Bankruptcy Code, (ii) a party’s right to liquidate the Transaction and to exercise any other remedies upon the occurrence of any Event of Default under the Agreement with respect to the other party to constitute a “contractual right” as described in the Bankruptcy Code, and (iii) each payment and delivery of cash, securities or other property hereunder to constitute a “margin payment” or “settlement payment” and a “transfer” as defined in the Bankruptcy Code.

(s) Notice of Certain Other Events. Counterparty covenants and agrees that:

(i) promptly following the public announcement of the results of any election by the holders of Shares with respect to the consideration due upon consummation of any Merger Event, Counterparty shall give Dealer written notice of the weighted average of the types and amounts of consideration received by holders of Shares upon consummation of such Merger Event (the date of such notification, the “Consideration Notification Date”); provided that in no event shall the Consideration Notification Date be later than the date on which such Merger Event is consummated; and

27

(ii) (A) Counterparty shall give Dealer commercially reasonable advance (but in no event less than one Exchange Business Day) written notice of the section or sections of the Indenture and, if applicable, the formula therein, pursuant to which any adjustment will be made to the Convertible Notes in connection with any Potential Adjustment Event, Merger Event or Tender Offer and (B) promptly following any such adjustment, Counterparty shall give Dealer written notice of the details of such adjustment.

(t) Wall Street Transparency and Accountability Act. In connection with Section 739 of the Wall Street Transparency and Accountability Act of 2010 (“WSTAA”), the parties hereby agree that neither the enactment of WSTAA or any regulation under the WSTAA, nor any requirement under WSTAA or an amendment made by WSTAA, shall limit or otherwise impair either party’s otherwise applicable rights to terminate, renegotiate, modify, amend or supplement this Confirmation or the Agreement, as applicable, arising from a termination event, force majeure, illegality, increased costs, regulatory change or similar event under this Confirmation, the Equity Definitions incorporated herein, or the Agreement (including, but not limited to, rights arising from Change in Law, Hedging Disruption, Increased Cost of Hedging, an Excess Ownership Position, or Illegality (as defined in the Agreement)).

(u) Agreements and Acknowledgements Regarding Hedging. Counterparty understands, acknowledges and agrees that: (A) at any time on and prior to the Expiration Date, Dealer and its affiliates may buy or sell Shares or other securities or buy or sell options or futures contracts or enter into swaps or other derivative securities in order to adjust its hedge position with respect to the Transaction; (B) Dealer and its affiliates also may be active in the market for Shares or other securities of the Issuer other than in connection with hedging activities in relation to the Transaction; (C) Dealer shall make its own determination as to whether, when or in what manner any hedging or market activities in securities of Issuer shall be conducted and shall do so in a manner that it deems appropriate to hedge its price and market risk with respect to the Relevant Prices; and (D) any market activities of Dealer and its affiliates with respect to Shares may affect the market price and volatility of Shares, as well as the Relevant Prices, each in a manner that may be adverse to Counterparty.

(v) Early Unwind. In the event the sale of the Convertible Notes is not consummated with the Investors for any reason, or Counterparty fails to deliver to Dealer opinions of counsel as required pursuant to Section 9(a), in each case by 5:00 p.m. (New York City time) on the Premium Payment Date, or such later date as agreed upon by the parties (the Premium Payment Date or such later date the “Early Unwind Date”), the Transaction shall automatically terminate (the “Early Unwind”), on the Early Unwind Date and (i) the Transaction and all of the respective rights and obligations of Dealer and Counterparty under the Transaction shall be cancelled and terminated and (ii) each party shall be released and discharged by the other party from and agrees not to make any claim against the other party with respect to any obligations or liabilities of the other party arising out of and to be performed in connection with the Transaction either prior to or after the Early Unwind Date. Each of Dealer and Counterparty represents and acknowledges to the other that, upon an Early Unwind, all obligations with respect to the Transaction shall be deemed fully and finally discharged.

(w) Payment by Counterparty. In the event that, following payment of the Premium, (i) an Early Termination Date occurs or is designated with respect to the Transaction as a result of a Termination Event or an Event of Default (other than an Event of Default arising under Section 5(a)(ii) or 5(a)(iv) of the Agreement) and, as a result, Counterparty owes to Dealer an amount calculated under Section 6(e) of the Agreement, or (ii) Counterparty owes to Dealer, pursuant to Section 12.7 or Section 12.9 of the Equity Definitions, an amount calculated under Section 12.8 of the Equity Definitions, such amount shall be deemed to be zero.

(x) Other Adjustments Pursuant to the Equity Definitions. Notwithstanding anything to the contrary in this Confirmation, solely for the purpose of adjusting the Cap Price, the terms “Potential Adjustment Event,” “Merger Event,” and “Tender Offer” shall each have the meanings assigned to

28

such term in the Equity Definitions (as amended by Section 9(j)(i)), and upon the occurrence of a Merger Date, the occurrence of a Tender Offer Date, or declaration by Counterparty of the terms of any Potential Adjustment Event, respectively, as such terms are defined in the Equity Definitions, the Calculation Agent shall determine in good faith and in a commercially reasonable manner whether such occurrence or declaration, as applicable, has had a material economic effect on the Transaction and, if so, shall, in its good faith and commercially reasonable discretion, adjust the Cap Price to preserve the fair value of the Options to Dealer; provided that in no event shall the Cap Price be less than the Strike Price; provided further that any adjustment to the Cap Price made pursuant to this Section 9(x) shall be made without duplication of any other adjustment hereunder.

(y) Standard for Adjustments. For the avoidance of doubt, whenever the Calculation Agent or Determining Party is called upon to make an adjustment pursuant to the terms of this Confirmation or the Equity Definitions to take into account the effect of an event, the Calculation Agent or Determining Party shall make such adjustment in conformity with the provisions hereof in a commercially reasonable manner by reference to the effect of such event on the Hedging Party, assuming that the Hedging Party maintains a commercially reasonable hedge position.
