| Re: | Additional 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 Barclays Bank PLC (“Dealer”), through its agent Barclays Capital Inc. (the “Agent”) and Enphase Energy, 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. This Confirmation shall replace any previous agreements and serve as the final documentation for the Transaction. Dealer is not a member of the Securities Investor Protection Corporation. Dealer is authorized by the Prudential Regulation Authority and regulated by the Financial Conduct Authority and the Prudential Regulation Authority.

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 Offering Memorandum dated February 24, 2021 (the “Offering Memorandum”) relating to the Convertible Senior Notes due 2026 (as originally issued by Counterparty, 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 575,000,000 (as increased by an aggregate principal amount of USD 57,500,000 pursuant to the exercise by the Initial Purchasers (as defined herein) of their over-allotment option to purchase additional Convertible Notes pursuant to the Purchase Agreement (as defined herein)) pursuant to an Indenture dated March 1, 2021 between Counterparty and U.S. Bank National Association, as trustee (the “Indenture”). In the event of any inconsistency between the terms defined in the Offering Memorandum, the Indenture and this Confirmation, this Confirmation shall govern. The parties acknowledge that this Confirmation is entered into on the date hereof with the understanding that (i) definitions set forth in the Indenture which are also defined herein by reference to the Indenture and (ii) sections of the Indenture that are referred to herein will conform to the descriptions thereof in the Offering Memorandum. If any such definitions in the Indenture or any such sections of the Indenture differ from the descriptions thereof in the Offering Memorandum, the descriptions thereof in the Offering Memorandum will govern for purposes of this Confirmation. 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 as in effect on the date of its execution, and if the Indenture is amended following such date (other than any amendment pursuant to Section 10.01(m) of the Indenture that, as determined by the Calculation Agent, conforms the Indenture to the description of Convertible Notes in the Offering Memorandum), any such amendment will be disregarded for purposes of this Confirmation 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) and (ii) the election that the “Cross Default” provisions of Section 5(a)(vi) of the Agreement shall apply to Dealer, with a “Threshold Amount” of 3% of shareholders’ equity of Dealer (provided that (a) the phrase “, or becoming capable at such time of being declared,” shall be deleted from clause (1) of such Section 5(a)(vi) of the Agreement, (b) “Specified Indebtedness” shall have 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.”)) on the Trade Date.

| 5 |

| Settlement Terms. |
| Settlement Method: | For any Option, Net Share Settlement; provided that if the Relevant Settlement Method set forth below for such Option is not Net Share Settlement, then the Settlement Method for such Option shall be such Relevant Settlement Method, but only if Counterparty, or the Trustee (or other agent authorized by Counterparty and previously identified to Dealer by Counterparty in writing) on behalf of Counterparty, shall have notified Dealer of the Relevant Settlement Method in the Notice of Exercise or Notice of Final Settlement Method, as applicable, for such Option.

| Relevant Settlement Method: | In respect of any Option:
|  | (i) if Counterparty has elected to settle its conversion obligations in respect of the related Convertible Note (A) entirely in Shares pursuant to Section 14.02(iv)(A) of the Indenture (together with cash in lieu of fractional Shares) (such settlement method, “Settlement in Shares”), (B) in a combination of cash and Shares pursuant to Section 14.04(iv)(C) of the Indenture with a Specified Cash Amount less than USD 1,000 or (C) in a combination of cash and Shares pursuant to Section 14.04(iv)(C) of the Indenture with a Specified Cash Amount equal to USD 1,000, then, in each case, the Relevant Settlement Method for such Option shall be Net Share Settlement;

| Net Share Settlement: | If Net Share Settlement is applicable to any Option exercised or deemed exercised hereunder, Dealer will deliver to Counterparty, on the relevant Settlement Date for each such Option, a number of Shares (the “Net Share Settlement Amount”) equal to the sum, for each Valid Day during the Settlement Averaging Period for each such Option, of (i) (a) the Daily Option Value for such Valid Day, divided by (b) the Relevant Price on such Valid Day, divided by (ii) the number of Valid Days in the Settlement Averaging Period; provided that in no event shall the Net Share Settlement Amount for any Option exceed a number of Shares equal to the Applicable Limit for such Option, divided by the Applicable Limit Price on the Settlement Date for such Option.

| 6 |

|  | Dealer will pay cash in lieu of delivering any fractional Shares to be delivered with respect to any Net Share Settlement Share Amount valued at the Relevant Price for the last Valid Day of the Settlement Averaging Period.
| Combination Settlement: | If Combination Settlement is applicable to any Option exercised or deemed exercised hereunder, Dealer will pay or deliver, as the case may be, to Counterparty, on the relevant Settlement Date for each such Option:
|  | (i) cash (the “Combination Settlement Cash Amount”) equal to the sum, for each Valid Day during the Settlement Averaging Period for such Option, of (A) an amount (the “Daily Combination Settlement Cash Amount”) equal to the lesser of (1) the product of (x) the Applicable Percentage and (y) the Specified Cash Amount minus USD 1,000 and (2) the Daily Option Value, divided by (B) the number of Valid Days in the Settlement Averaging Period; provided that if the calculation in clause (A) above results in zero or a negative number for any Valid Day, the Daily Combination Settlement Cash Amount for such Valid Day shall be deemed to be zero; and
|  | (ii)   Shares (the “Combination Settlement Share Amount”) equal to the sum, for each Valid Day during the Settlement Averaging Period for such Option, of a number of Shares for such Valid Day (the “Daily Combination Settlement Share Amount”) equal to (A) (1) the Daily Option Value on such Valid Day minus the Daily Combination Settlement Cash Amount for such Valid Day, divided by (2) the Relevant Price on such Valid Day, divided by (B) the number of Valid Days in the Settlement Averaging Period; provided that if the calculation in sub-clause (A)(1) above results in zero or a negative number for any Valid Day, the Daily Combination Settlement Share Amount for such Valid Day shall be deemed to be zero;
|  | provided that in no event shall the sum of (x) the Combination Settlement Cash Amount for any Option, and (y) the Combination Settlement Share Amount for such Option, multiplied by the Applicable Limit Price on the Settlement Date for such Option, exceed the Applicable Limit for such Option.
|  | Dealer will pay cash in lieu of delivering any fractional Shares to be delivered with respect to any Combination Settlement Share Amount valued at the Relevant Price for the last Valid Day of the Settlement Averaging Period.

| 7 |

| Cash Settlement: | If Cash Settlement is applicable to any Option exercised or deemed exercised hereunder, in lieu of Section 8.1 of the Equity Definitions, Dealer will pay to Counterparty, on the relevant Settlement Date for each such Option, an amount of cash (the “Cash Settlement Amount”) equal to the sum, for each Valid Day during the Settlement Averaging Period for such Option, of (i) the Daily Option Value for such Valid Day, divided by (ii) the number of Valid Days in the Settlement Averaging Period; provided that in no event shall the Cash Settlement Amount exceed the Applicable Limit for such Option.
| Daily Option Value: | For any Valid Day, an amount equal to (i) the Option Entitlement on such Valid Day, multiplied by (ii) the Relevant Price on such Valid Day less the Strike Price on such Valid Day; provided that if the calculation contained in clause (ii) above results in a negative number, the Daily Option Value for such Valid Day shall be deemed to be zero. In no event will the Daily Option Value be less than zero.
| Make-Whole Adjustment: | Notwithstanding anything to the contrary herein, in respect of any exercise of Options relating to a conversion of Convertible Notes for which additional Shares will be added to the “Conversion Rate” (as defined in the Indenture) as determined pursuant to Section 14.03 of the Indenture, the Daily Option Value shall be calculated as if the Option Entitlement included the Applicable Percentage of the number of such additional Shares as determined with reference to the adjustment set forth in such Section 14.03 of the Indenture; provided that if the sum of (i) the product of (a) the number of Shares (if any) deliverable by Dealer to Counterparty per exercised Option and (b) the Applicable Limit Price on the Settlement Date and (ii) the amount of cash (if any) payable by Dealer to Counterparty per exercised Option would otherwise exceed the amount per Option, as determined by the Calculation Agent, that would be payable by Dealer under Section 6 of the Agreement if (x) the relevant Conversion Date were an Early Termination Date resulting from an Additional Termination Event with respect to which the Transaction was the sole Affected Transaction and Counterparty was the sole Affected Party and (y) Section 14.03 of the Indenture were deleted, then each Daily Option Value shall be proportionately reduced to the extent necessary to eliminate such excess.
| Applicable Limit: | For any Option, an amount of cash equal to the Applicable Percentage, multiplied by the excess of (i) the aggregate of (A) the amount of cash, if any, paid to the Holder of the related Convertible Note upon conversion of such Convertible Note and (B) the number of Shares, if any, delivered to the Holder of the related Convertible Note upon conversion of such Convertible Note multiplied by the Applicable Limit Price on the Settlement Date for such Option, over (ii) USD 1,000.

The Relevant Price will be determined without regard to after-hours trading or any other trading outside of the regular trading session trading hours.
| Settlement Averaging Period: | For any Option and regardless of the Settlement Method applicable to such Option:

| 9 |

|  | (ii)   with respect to any Convertible Notes called for redemption and converted pursuant to Section 14.01(b)(v) of the Indenture, if the related Conversion Date occurs on or after the date on which Counterparty issues a Redemption Notice with respect to such Convertible Notes in accordance with Section 16.02 of the Indenture and prior to the close of business on the Scheduled Valid Day immediately preceding the related Redemption Date, the 20 consecutive Valid Days commencing on, and including, the 21st Scheduled Valid Day immediately prior to such Redemption Date; and or

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).

| 8. | Representations and Warranties of Counterparty.

| (a) | Representations and Warranties of Counterparty. Each of the representations and warranties of Counterparty set forth in Section 2 of the Purchase Agreement (the “Purchase Agreement”), dated as of February 24, 2021, among Counterparty and BofA Securities, Inc. and Barclays Capital Inc., as representatives of the initial purchasers party thereto (the “Initial Purchasers”), are true and correct and are hereby deemed to be repeated to Dealer as if set forth herein. Counterparty hereby further represents and warrants to Dealer on the date hereof and on and as of the Premium Payment Date that:

| (i) | Counterparty has all necessary corporate power and authority to execute, deliver and perform its obligations in respect of the Transaction; such execution, delivery and performance have been duly authorized by all necessary corporate action on Counterparty’s part; and this Confirmation has been duly and validly executed and delivered by Counterparty and constitutes its valid and binding obligation, enforceable against Counterparty in accordance with its terms, subject to applicable bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and similar laws affecting creditors’ rights and remedies generally, and subject, as to enforceability, to general principles of equity, including principles of commercial reasonableness, good faith and fair dealing (regardless of whether enforcement is sought in a proceeding at law or in equity) and except that rights to indemnification and contribution hereunder may be limited by federal or state securities laws or public policy relating thereto.

| (ii) | Neither the execution and delivery of this Confirmation nor the incurrence or performance of obligations of Counterparty hereunder will conflict with or result in a breach of (A) the certificate of incorporation or by-laws (or any equivalent documents) of Counterparty, or (B) any applicable law or regulation, or any order, writ, injunction or decree of any court or governmental authority or agency, or (C) any agreement or instrument to which Counterparty or any of its subsidiaries is a party or by which Counterparty or any of its subsidiaries is bound or to which Counterparty or any of its subsidiaries is subject, or constitute a default under, or result in the creation of any lien under, any such agreement or instrument, except for any such conflicts, breaches, defaults or lien creations in the cases of clause (C) above that would not adversely affect the ability of Counterparty to fulfill its obligations under this Transaction.

15

| (iii) | No consent, approval, authorization, or order of, or filing with, any governmental agency or body or any court is required in connection with the execution, delivery or performance by Counterparty of this Confirmation, except such as have been obtained or made and such as may be required under the Securities Act or state securities laws.

| (iv) | Counterparty is not and, after consummation of the transactions contemplated hereby, will not be required to register as an “investment company” as such term is defined in the Investment Company Act of 1940, as amended.

| (v) | Counterparty is in compliance, in all material respects, with its periodic reporting obligations under the Exchange Act.

| (vi) | Counterparty (A) is capable of evaluating investment risks independently, both in general and with regard to all transactions and investment strategies involving a security or securities; (B) will exercise independent judgment in evaluating the recommendations of any broker-dealer or its associated persons, unless it has otherwise notified the broker-dealer in writing; and (C) has total assets of at least $50 million.

| (vii) | Counterparty acknowledges that the Transaction may constitute a purchase of its equity securities. Counterparty further acknowledges that, pursuant to the provisions of the Coronavirus Aid, Relief and Economic Security Act (the “Cares Act”), the Counterparty will be required to agree to certain time-bound restrictions on its ability to purchase its equity securities if it receives loans, loan guarantees or direct loans (as that term is defined in the Cares Act) under section 4003(b) of the Cares Act. Counterparty further acknowledges that it may be required to agree to certain time-bound restrictions on its ability to purchase its equity securities if it receives loans, loan guarantees or direct loans (as that term is defined in the Cares Act) under programs or facilities established by the Board of Governors of the Federal Reserve System for the purpose of providing liquidity to the financial system. Accordingly, Counterparty represents and warrants that neither it nor any of its subsidiaries has applied, and throughout the term of the Transaction neither it nor any of its subsidiaries shall apply, for a loan, loan guarantee, direct loan (as that term is defined in the Cares Act) or other investment, or to receive any financial assistance or relief (howsoever defined) under any program or facility established in any jurisdiction that (a) is established under applicable law, including without limitation the Cares Act and the Federal Reserve Act, as amended, and (b) requires, as a condition of such loan, loan guarantee, direct loan (as that term is defined in the Cares Act), investment, financial assistance or relief, that the Counterparty agree, attest, certify or warrant that neither it nor any of its subsidiaries has, as of the date specified in such condition, repurchased, or will repurchase, any equity security of Counterparty. Counterparty further represents and warrants that the Premium is not being paid, in whole or in part, directly or indirectly, with funds received under or pursuant to any program or facility established in any jurisdiction, including the U.S. Small Business Administration’s “Paycheck Protection Program”, that (a) is established under applicable law (whether in existence as of the Trade Date or subsequently enacted, adopted or amended), including without limitation the CARES Act and the Federal Reserve Act, as amended, and (b) requires under such applicable law (or any regulation, guidance, interpretation or other pronouncement of a governmental authority with jurisdiction for such program or facility) that such funds be used for specified or enumerated purposes that do not include the purchase of the Transaction (either by specific reference to the Transaction or by general reference to transactions with the attributes of the Transaction in all relevant respects).

| (b) | Each of Dealer and Counterparty agrees and represents that it is an “eligible contract participant” (as such term is defined in Section 1a(18) of the Commodity Exchange Act, as amended (the “CEA”), other than a person that is an eligible contract participant under Section 1a(18)(C) of the CEA).

16

| 9. | Other Provisions.

| (a) | Opinions. Counterparty shall deliver to Dealer an opinion of counsel, dated as of the Trade Date, with respect to (i) the matters set forth in Section 8(a)(ii)(B) and Section 8(a)(iii) of this Confirmation to the knowledge of counsel, (ii) due incorporation, existence and good standing of Counterparty in Delaware, (iii) the due authorization, execution and delivery of this Confirmation, and, (iv) in respect of the execution, delivery and performance of this Confirmation, the absence of any conflict with or breach of any material agreement required to be filed as an exhibit to Counterparty’s Annual Report on Form 10-K, Counterparty’s certificate of incorporation or Counterparty’s by-laws. 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 101.3 million (in the case of the first such notice) or (ii) thereafter more than 17.9 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 losses (including losses relating to Dealer’s hedging activities as a consequence of becoming, or of the risk of becoming, a Section 16 “insider”, including without limitation, any forbearance from hedging activities or cessation of hedging activities and any losses in connection therewith with respect to the Transaction), claims, damages, judgments, liabilities and expenses (including reasonable attorney’s fees), joint or several, which an Indemnified Person may become subject to, 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 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 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. If the indemnification provided for in this paragraph is unavailable to an Indemnified Person or insufficient in respect of any 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.

17

| (c) | Regulation M. Counterparty is not on the Trade Date engaged in a distribution, as such term is used in Regulation M under the Securities Exchange Act of 1934, as amended (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 manipulate the price of the Shares (or any security convertible into or exchangeable for the Shares) 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 (the “Code”);

| (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 commercially reasonable costs and expenses, including commercially reasonable counsel fees, incurred by Dealer in connection with such transfer or assignment.

18

| (ii) | Dealer may, without Counterparty’s consent, transfer or assign (such transfer or assignment, a “Transfer”) 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 Transfer, 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) with Counterparty’s consent (not to be unreasonably withheld or delayed) 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 rate such third party, 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 shall be a “dealer in securities” within the meaning of Section 475(c)(1) of the Code or (y) the Transfer will not result in a deemed exchange by Counterparty within the meaning of Section 1001 of the Code; and provided further that Dealer shall provide notice to Counterparty following any such Transfer. If at any time at which (A) the Section 16 Percentage exceeds 8.0%, (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). 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 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 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.

19

| (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 (each, a “Dealer Designated Affiliate”) 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 under this Confirmation to the extent such Dealer Designated Affiliate fully performs the obligations designated by Dealer to such Dealer Designated Affiliate under this Section 9(e)(iii).

| (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 that would be customarily applicable to transactions of this type by the dealers in this market as determined by the Calculation Agent, 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 (the first of which will be such Nominal Settlement Date and the last of which will be no later than the twentieth (20th) Exchange Business Day following 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.

| (g) | Role of Agent. Each of Dealer and Counterparty acknowledges to and agrees with the other party hereto and to and with the Agent that (i) the Agent is acting as agent for Dealer under the Transaction pursuant to instructions from such party, (ii) the Agent is not a principal or party to the Transaction, and may transfer its rights and obligations with respect to the Transaction, (iii) the Agent shall have no responsibility, obligation or liability, by way of issuance, guaranty, endorsement or otherwise in any manner with respect to the performance of either party under the Transaction, (iv) Dealer and the Agent have not given, and Counterparty is not relying (for purposes of making any investment decision or otherwise) upon, any statements, opinions or representations (whether written or oral) of Dealer or the Agent, other than the representations expressly set forth in this Confirmation or the Agreement, and (v) each party agrees to proceed solely against the other party, and not the Agent, to collect or recover any money or securities owed to it in connection with the Transaction. Each party hereto acknowledges and agrees that the Agent is an intended third party beneficiary hereunder. Counterparty acknowledges that the Agent is an affiliate of Dealer. Dealer will be acting for its own account in respect of this Confirmation and the Transaction contemplated hereunder.

20

| (h) | Submission to Jurisdiction. THE PARTIES HERETO IRREVOCABLY SUBMIT TO THE EXCLUSIVE JURISDICTION OF THE COURTS OF THE STATE OF NEW YORK AND THE UNITED STATES COURT FOR THE SOUTHERN DISTRICT OF NEW YORK IN CONNECTION WITH ALL MATTERS RELATING HERETO AND WAIVE ANY OBJECTION TO THE LAYING OF VENUE IN, AND ANY CLAIM OF INCONVENIENT FORUM WITH RESPECT TO, THESE COURTS.

| (i) | Additional Termination Events.

| (i) | 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, 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.

| (ii) | Promptly (and in any event within five Scheduled Trading Days) following any (i) repurchase (which, for the avoidance of doubt, includes any exchange transaction) and cancellation of Convertible Notes, including without limitation pursuant to Article 15 of the Indenture in connection with a “Fundamental Change” (as defined in the Indenture) or (ii) any Convertible Notes are redeemed (whether pursuant to Section 16.01 of the Indenture or otherwise) by Counterparty and are no longer outstanding under the Indenture, (such event, a “Repurchase Event”), Counterparty may notify Dealer in writing of such Repurchase Event and the number of Convertible Notes subject to such Repurchase Event (any such notice, a “Repurchase Notice”). Notwithstanding anything to the contrary in this Confirmation, the receipt by Dealer from Counterparty of (x) any Repurchase Notice, within the applicable time period set forth in the preceding sentence, and (y) a written representation and warranty by Counterparty that, as of the date of such Repurchase Notice, Counterparty is not in possession of any material non-public information regarding Counterparty or the Shares, shall constitute an Additional Termination Event as provided in this paragraph. Upon receipt of any such Repurchase Notice and the related written representation and warranty, Dealer shall promptly designate an Exchange Business Day following receipt of such Repurchase Notice (which Exchange Business Day shall be on or as promptly as reasonably practicable after the related repurchase settlement date for the relevant Repurchase Event) as an Early Termination Date with respect to the portion of this Transaction corresponding to a number of Options (the “Repurchase Options”) equal to the lesser of (A) the number of such Convertible Notes specified in such Repurchase Notice minus the number of “Repurchase Options” (as defined in the Base Call Option Confirmation), if any, that relate to such Convertible Notes divided by the Applicable Percentage 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 Repurchase Options. Any payment hereunder with respect to such termination 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 this Transaction and a Number of Options equal to the number of Repurchase Options, (2) Counterparty were the sole Affected Party with respect to such Additional Termination Event, (3) no adjustment to the “Conversion Rate” (as defined in the Indenture) for the Convertible Notes has occurred pursuant to any Excluded Provision, (4) the corresponding Convertible Notes remaining outstanding as if the circumstances related to the Repurchase Event had not occurred, (5) the relevant Repurchase Event and any conversions, adjustments, agreements, payments, deliveries or acquisitions by or on behalf of Counterparty leading thereto had not occurred, and (6) the terminated portion of the Transaction were the sole Affected Transaction.

21

| (j) | Amendments to Equity Definitions.

| (i) | Section 12.6(a)(ii) of the Equity Definitions is hereby amended by (1) deleting from the fourth line thereof the word “or” after the word “official” and inserting a comma therefor, and (2) deleting the semi-colon at the end of subsection (B) thereof and inserting the following words therefor “or (C) 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.”

| (ii) | Section 12.9(b)(i) of the Equity Definitions is hereby amended by (1) replacing “either party may elect” with “Dealer may elect” and (2) replacing “notice to the other party” with “notice to Counterparty” in the first sentence of such section.

| (k) | No Setoff. Each party waives any and all rights it may have to set off obligations arising under the Agreement and the Transaction against other obligations between the parties, whether arising under any other agreement, applicable 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 all holders of Shares consists solely of cash, (ii) 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 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(a)(v) as of the date of such election and (c) Dealer agrees, in its sole 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.

22

Share Termination Unit Price: | The value to Dealer of property contained in one Share Termination Delivery Unit, as determined by the Calculation Agent in good faith and in a commercially reasonable manner 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 Price the Calculation Agent may consider the purchase price paid in connection with the purchase of Share Termination Delivery Property.
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 the 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.

The purpose of this letter agreement (this “Confirmation”) is to confirm the terms and conditions of the call option transaction entered into between Credit Suisse Capital LLC (“Dealer”), represented by Credit Suisse Securities (USA) LLC (“Agent”) as its agent, and Enphase Energy, 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. This Confirmation shall replace any previous agreements and serve as the final documentation for the Transaction.

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 Offering Memorandum dated February 24, 2021 (the “Offering Memorandum”) relating to the Convertible Senior Notes due 2026 (as originally issued by Counterparty, 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 575,000,000 (as increased by an aggregate principal amount of USD 57,500,000 pursuant to the exercise by the Initial Purchasers (as defined herein) of their over-allotment option to purchase additional Convertible Notes pursuant to the Purchase Agreement (as defined herein)) pursuant to an Indenture dated March 1, 2021 between Counterparty and U.S. Bank National Association, as trustee (the “Indenture”). In the event of any inconsistency between the terms defined in the Offering Memorandum, the Indenture and this Confirmation, this Confirmation shall govern. The parties acknowledge that this Confirmation is entered into on the date hereof with the understanding that (i) definitions set forth in the Indenture which are also defined herein by reference to the Indenture and (ii) sections of the Indenture that are referred to herein will conform to the descriptions thereof in the Offering Memorandum. If any such definitions in the Indenture or any such sections of the Indenture differ from the descriptions thereof in the Offering Memorandum, the descriptions thereof in the Offering Memorandum will govern for purposes of this Confirmation. 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 as in effect on the date of its execution, and if the Indenture is amended following such date (other than any amendment pursuant to Section 10.01(m) of the Indenture that, as determined by the Calculation Agent, conforms the Indenture to the description of Convertible Notes in the Offering Memorandum), any such amendment will be disregarded for purposes of this Confirmation 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) and (ii) the election that the “Cross Default” provisions of Section 5(a)(vi) of the Agreement shall apply to Dealer, with a “Threshold Amount” of 3% of shareholders’ equity of Dealer (provided that (a) the phrase “, or becoming capable at such time of being declared,” shall be deleted from clause (1) of such Section 5(a)(vi) of the Agreement, (b) “Specified Indebtedness” shall have 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.”)) on the Trade Date.

| Net Share Settlement: | If Net Share Settlement is applicable to any Option exercised or deemed exercised hereunder, Dealer will deliver to Counterparty, on the relevant Settlement Date for each such Option, a number of Shares (the “Net Share Settlement Amount”) equal to the sum, for each Valid Day during the Settlement Averaging Period for each such Option, of (i) (a) the Daily Option Value for such Valid Day, divided by (b) the Relevant Price on such Valid Day, divided by (ii) the number of Valid Days in the Settlement Averaging Period; provided that in no event shall the Net Share Settlement Amount for any Option exceed a number of Shares equal to the Applicable Limit for such Option, divided by the Applicable Limit Price on the Settlement Date for such Option.
|  | Dealer will pay cash in lieu of delivering any fractional Shares to be delivered with respect to any Net Share Settlement Share Amount valued at the Relevant Price for the last Valid Day of the Settlement Averaging Period.

6

| Combination Settlement: | If Combination Settlement is applicable to any Option exercised or deemed exercised hereunder, Dealer will pay or deliver, as the case may be, to Counterparty, on the relevant Settlement Date for each such Option:

| (i) | cash (the “Combination Settlement Cash Amount”) equal to the sum, for each Valid Day during the Settlement Averaging Period for such Option, of (A) an amount (the “Daily Combination Settlement Cash Amount”) equal to the lesser of (1) the product of (x) the Applicable Percentage and (y) the Specified Cash Amount minus USD 1,000 and (2) the Daily Option Value, divided by (B) the number of Valid Days in the Settlement Averaging Period; provided that if the calculation in clause (A) above results in zero or a negative number for any Valid Day, the Daily Combination Settlement Cash Amount for such Valid Day shall be deemed to be zero; and

| (ii) | Shares (the “Combination Settlement Share Amount”) equal to the sum, for each Valid Day during the Settlement Averaging Period for such Option, of a number of Shares for such Valid Day (the “Daily Combination Settlement Share Amount”) equal to (A) (1) the Daily Option Value on such Valid Day minus the Daily Combination Settlement Cash Amount for such Valid Day, divided by (2) the Relevant Price on such Valid Day, divided by (B) the number of Valid Days in the Settlement Averaging Period; provided that if the calculation in sub-clause (A)(1) above results in zero or a negative number for any Valid Day, the Daily Combination Settlement Share Amount for such Valid Day shall be deemed to be zero;

|  | provided that in no event shall the sum of (x) the Combination Settlement Cash Amount for any Option, and (y) the Combination Settlement Share Amount for such Option, multiplied by the Applicable Limit Price on the Settlement Date for such Option, exceed the Applicable Limit for such Option.
|  | Dealer will pay cash in lieu of delivering any fractional Shares to be delivered with respect to any Combination Settlement Share Amount valued at the Relevant Price for the last Valid Day of the Settlement Averaging Period.
| Cash Settlement: | If Cash Settlement is applicable to any Option exercised or deemed exercised hereunder, in lieu of Section 8.1 of the Equity Definitions, Dealer will pay to Counterparty, on the relevant Settlement Date for each such Option, an amount of cash (the “Cash Settlement Amount”) equal to the sum, for each Valid Day during the Settlement Averaging Period for such Option, of (i) the Daily Option Value for such Valid Day, divided by (ii) the number of Valid Days in the Settlement Averaging Period; provided that in no event shall the Cash Settlement Amount exceed the Applicable Limit for such Option.

7

| Daily Option Value: | For any Valid Day, an amount equal to (i) the Option Entitlement on such Valid Day, multiplied by (ii) the Relevant Price on such Valid Day less the Strike Price on such Valid Day; provided that if the calculation contained in clause (ii) above results in a negative number, the Daily Option Value for such Valid Day shall be deemed to be zero. In no event will the Daily Option Value be less than zero.
| Make-Whole Adjustment: | Notwithstanding anything to the contrary herein, in respect of any exercise of Options relating to a conversion of Convertible Notes for which additional Shares will be added to the “Conversion Rate” (as defined in the Indenture) as determined pursuant to Section 14.03 of the Indenture, the Daily Option Value shall be calculated as if the Option Entitlement included the Applicable Percentage of the number of such additional Shares as determined with reference to the adjustment set forth in such Section 14.03 of the Indenture; provided that if the sum of (i) the product of (a) the number of Shares (if any) deliverable by Dealer to Counterparty per exercised Option and (b) the Applicable Limit Price on the Settlement Date and (ii) the amount of cash (if any) payable by Dealer to Counterparty per exercised Option would otherwise exceed the amount per Option, as determined by the Calculation Agent, that would be payable by Dealer under Section 6 of the Agreement if (x) the relevant Conversion Date were an Early Termination Date resulting from an Additional Termination Event with respect to which the Transaction was the sole Affected Transaction and Counterparty was the sole Affected Party and (y) Section 14.03 of the Indenture were deleted, then each Daily Option Value shall be proportionately reduced to the extent necessary to eliminate such excess.
| Applicable Limit: | For any Option, an amount of cash equal to the Applicable Percentage, multiplied by the excess of (i) the aggregate of (A) the amount of cash, if any, paid to the Holder of the related Convertible Note upon conversion of such Convertible Note and (B) the number of Shares, if any, delivered to the Holder of the related Convertible Note upon conversion of such Convertible Note multiplied by the Applicable Limit Price on the Settlement Date for such Option, over (ii) USD 1,000.

| Valid Day: | A day on which (i) there is no Market Disruption Event and (ii) trading in the Shares generally occurs on the Exchange or, if the Shares are not then listed on the Exchange, on the principal other United States national or regional securities exchange on which the Shares are then listed or, if the Shares are not then listed on a United States national or regional securities exchange, on the principal other market on which the Shares are then listed or admitted for trading.

If the Shares are not so listed or admitted for trading, “Scheduled Valid Day” means a Business Day.
| Business Day: | Any day other than a Saturday, a Sunday or a day on which the Federal Reserve Bank of New York is authorized or required by law or executive order to close or be closed.
| Relevant Price: | On any Valid Day, the per Share volume-weighted average price as displayed under the heading “Bloomberg VWAP” on Bloomberg page ENPH <equity> AQR (or its equivalent successor if such page is not available) in respect of the period from the scheduled opening time of the Exchange to the Scheduled Closing Time of the Exchange on such Valid Day (or if such volume-weighted average price is unavailable, the market value of one Share on such Valid Day, as determined by the Calculation Agent in good faith and in a commercially reasonable manner using, if practicable, a volume-weighted average method). The Relevant Price will be determined without regard to after-hours trading or any other trading outside of the regular trading session trading hours.
| Settlement Averaging Period: | For any Option and regardless of the Settlement Method applicable to such Option:

| (i) | subject to clause (ii), if the related Conversion Date occurs prior to the Averaging Period Threshold Date, the 20 consecutive Valid Days commencing on, and including, the second Valid Day following such Conversion Date; or

| (ii) | with respect to any Convertible Notes called for redemption and converted pursuant to Section 14.01(b)(v) of the Indenture, if the related Conversion Date occurs on or after the date on which Counterparty issues a Redemption Notice with respect to such Convertible Notes in accordance with Section 16.02 of the Indenture and prior to the close of business on the Scheduled Valid Day immediately preceding the related Redemption Date, the 20 consecutive Valid Days commencing on, and including, the 21st Scheduled Valid Day immediately prior to such Redemption Date; and or

9

| (iii) | subject to clause (ii), if the related Conversion Date occurs on or following the Averaging Period Threshold Date, the 20 consecutive Valid Days commencing on, and including, the 21st Scheduled Valid Day immediately prior to the Expiration Date.

| Other Applicable Provisions: | The provisions of Sections 9.1(c), 9.8, 9.9 and 9.11 of the Equity Definitions will be applicable, except that all references in such provisions to “Physically-settled” shall be read as references to “Share Settled”. “Share Settled” in relation to any Option means that Net Share Settlement or Combination Settlement is applicable to that Option.
| Representation and Agreement: | Notwithstanding anything to the contrary in the Equity Definitions (including, but not limited to, Section 9.11 thereof), the parties acknowledge that (i) any Shares delivered to Counterparty shall be, upon delivery, subject to restrictions and limitations arising from Counterparty’s status as issuer of the Shares under applicable securities laws, (ii) Dealer may deliver any Shares required to be delivered hereunder in certificated form in lieu of delivery through the Clearance System and (iii) any Shares delivered to Counterparty may be “restricted securities” (as defined in Rule 144 under the Securities Act of 1933, as amended (the “Securities Act”)).

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).

10

| 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.

| 8. | Representations and Warranties of Counterparty.

| (a) | Representations and Warranties of Counterparty. Each of the representations and warranties of Counterparty set forth in Section 2 of the Purchase Agreement (the “Purchase Agreement”), dated as of February 24, 2021, among Counterparty and BofA Securities, Inc. and Barclays Capital Inc., as representatives of the initial purchasers party thereto (the “Initial Purchasers”), are true and correct and are hereby deemed to be repeated to Dealer as if set forth herein. Counterparty hereby further represents and warrants to Dealer on the date hereof and on and as of the Premium Payment Date that:

| (i) | Counterparty has all necessary corporate power and authority to execute, deliver and perform its obligations in respect of the Transaction; such execution, delivery and performance have been duly authorized by all necessary corporate action on Counterparty’s part; and this Confirmation has been duly and validly executed and delivered by Counterparty and constitutes its valid and binding obligation, enforceable against Counterparty in accordance with its terms, subject to applicable bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and similar laws affecting creditors’ rights and remedies generally, and subject, as to enforceability, to general principles of equity, including principles of commercial reasonableness, good faith and fair dealing (regardless of whether enforcement is sought in a proceeding at law or in equity) and except that rights to indemnification and contribution hereunder may be limited by federal or state securities laws or public policy relating thereto.

| (ii) | Neither the execution and delivery of this Confirmation nor the incurrence or performance of obligations of Counterparty hereunder will conflict with or result in a breach of (A) the certificate of incorporation or by-laws (or any equivalent documents) of Counterparty, or (B) any applicable law or regulation, or any order, writ, injunction or decree of any court or governmental authority or agency, or (C) any agreement or instrument to which Counterparty or any of its subsidiaries is a party or by which Counterparty or any of its subsidiaries is bound or to which Counterparty or any of its subsidiaries is subject, or constitute a default under, or result in the creation of any lien under, any such agreement or instrument, except for any such conflicts, breaches, defaults or lien creations in the cases of clause (C) above that would not adversely affect the ability of Counterparty to fulfill its obligations under this Transaction.

15

| (iii) | No consent, approval, authorization, or order of, or filing with, any governmental agency or body or any court is required in connection with the execution, delivery or performance by Counterparty of this Confirmation, except such as have been obtained or made and such as may be required under the Securities Act or state securities laws.

| (iv) | Counterparty is not and, after consummation of the transactions contemplated hereby, will not be required to register as an “investment company” as such term is defined in the Investment Company Act of 1940, as amended.

| (v) | Counterparty is in compliance, in all material respects, with its periodic reporting obligations under the Exchange Act.

| (vi) | Counterparty (A) is capable of evaluating investment risks independently, both in general and with regard to all transactions and investment strategies involving a security or securities; (B) will exercise independent judgment in evaluating the recommendations of any broker-dealer or its associated persons, unless it has otherwise notified the broker-dealer in writing; and (C) has total assets of at least $50 million.

| (vii) | Counterparty acknowledges that the Transaction may constitute a purchase of its equity securities. Counterparty further acknowledges that, pursuant to the provisions of the Coronavirus Aid, Relief and Economic Security Act (the “Cares Act”), the Counterparty will be required to agree to certain time-bound restrictions on its ability to purchase its equity securities if it receives loans, loan guarantees or direct loans (as that term is defined in the Cares Act) under section 4003(b) of the Cares Act. Counterparty further acknowledges that it may be required to agree to certain time-bound restrictions on its ability to purchase its equity securities if it receives loans, loan guarantees or direct loans (as that term is defined in the Cares Act) under programs or facilities established by the Board of Governors of the Federal Reserve System for the purpose of providing liquidity to the financial system. Accordingly, Counterparty represents and warrants that neither it nor any of its subsidiaries has applied, and throughout the term of the Transaction neither it nor any of its subsidiaries shall apply, for a loan, loan guarantee, direct loan (as that term is defined in the Cares Act) or other investment, or to receive any financial assistance or relief (howsoever defined) under any program or facility established in any jurisdiction that (a) is established under applicable law, including without limitation the Cares Act and the Federal Reserve Act, as amended, and (b) requires, as a condition of such loan, loan guarantee, direct loan (as that term is defined in the Cares Act), investment, financial assistance or relief, that the Counterparty agree, attest, certify or warrant that neither it nor any of its subsidiaries has, as of the date specified in such condition, repurchased, or will repurchase, any equity security of Counterparty. Counterparty further represents and warrants that the Premium is not being paid, in whole or in part, directly or indirectly, with funds received under or pursuant to any program or facility established in any jurisdiction, including the U.S. Small Business Administration’s “Paycheck Protection Program”, that (a) is established under applicable law (whether in existence as of the Trade Date or subsequently enacted, adopted or amended), including without limitation the CARES Act and the Federal Reserve Act, as amended, and (b) requires under such applicable law (or any regulation, guidance, interpretation or other pronouncement of a governmental authority with jurisdiction for such program or facility) that such funds be used for specified or enumerated purposes that do not include the purchase of the Transaction (either by specific reference to the Transaction or by general reference to transactions with the attributes of the Transaction in all relevant respects).

| (b) | Each of Dealer and Counterparty agrees and represents that it is an “eligible contract participant” (as such term is defined in Section 1a(18) of the Commodity Exchange Act, as amended (the “CEA”), other than a person that is an eligible contract participant under Section 1a(18)(C) of the CEA).

16

| 9. | Other Provisions.

| (a) | Opinions. Counterparty shall deliver to Dealer an opinion of counsel, dated as of the Trade Date, with respect to (i) the matters set forth in Section 8(a)(ii)(B) and Section 8(a)(iii) of this Confirmation to the knowledge of counsel, (ii) due incorporation, existence and good standing of Counterparty in Delaware, (iii) the due authorization, execution and delivery of this Confirmation, and, (iv) in respect of the execution, delivery and performance of this Confirmation, the absence of any conflict with or breach of any material agreement required to be filed as an exhibit to Counterparty’s Annual Report on Form 10-K, Counterparty’s certificate of incorporation or Counterparty’s by-laws. 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 101.3 million (in the case of the first such notice) or (ii) thereafter more than 18.0 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 losses (including losses relating to Dealer’s hedging activities as a consequence of becoming, or of the risk of becoming, a Section 16 “insider”, including without limitation, any forbearance from hedging activities or cessation of hedging activities and any losses in connection therewith with respect to the Transaction), claims, damages, judgments, liabilities and expenses (including reasonable attorney’s fees), joint or several, which an Indemnified Person may become subject to, 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 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 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. If the indemnification provided for in this paragraph is unavailable to an Indemnified Person or insufficient in respect of any 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.

17

| (c) | Regulation M. Counterparty is not on the Trade Date engaged in a distribution, as such term is used in Regulation M under the Securities Exchange Act of 1934, as amended (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 manipulate the price of the Shares (or any security convertible into or exchangeable for the Shares) 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 (the “Code”);

| (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 commercially reasonable costs and expenses, including commercially reasonable counsel fees, incurred by Dealer in connection with such transfer or assignment.

| (ii) | Dealer may, without Counterparty’s consent, transfer or assign (such transfer or assignment, a “Transfer”) 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 Transfer, 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) with Counterparty’s consent (not to be unreasonably withheld or delayed) 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 rate such third party, 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 shall be a “dealer in securities” within the meaning of Section 475(c)(1) of the Code or (y) the Transfer will not result in a deemed exchange by Counterparty within the meaning of Section 1001 of the Code; and provided further that Dealer shall provide notice to Counterparty following any such Transfer. If at any time at which (A) the Section 16 Percentage exceeds 8.0%, (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). 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 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 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.

19

| (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 (each, a “Dealer Designated Affiliate”) 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 under this Confirmation to the extent such Dealer Designated Affiliate fully performs the obligations designated by Dealer to such Dealer Designated Affiliate under this Section 9(e)(iii).

| (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 that would be customarily applicable to transactions of this type by the dealers in this market as determined by the Calculation Agent, 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 (the first of which will be such Nominal Settlement Date and the last of which will be no later than the twentieth (20th) Exchange Business Day following 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.

| (g) | Role of Agent. As a broker-dealer registered with the U.S. Securities and Exchange Commission (“SEC”), Credit Suisse Securities (USA) LLC in its capacity as Agent will be responsible for (i) effecting the Transactions, (ii) issuing all required confirmations and statements to Dealer and Counterparty, (iii) maintaining books and records relating to the Transactions as required by Rules 17a-3 and 17a-4 under the Exchange Act and (iv) unless otherwise requested by Counterparty, receiving, delivering, and safeguarding Counterparty’s funds and any securities in connection with each Transaction, in compliance with Rule 15c3-3 under the Exchange Act.

Credit Suisse Securities (USA) LLC is acting in connection with the Transaction solely in its capacity as Agent for Dealer and Counterparty pursuant to instructions from Dealer and Counterparty. Credit Suisse Securities (USA) LLC shall have no responsibility or personal liability to Dealer or Counterparty arising from any failure by Dealer or Counterparty to pay or perform any obligations hereunder, or to monitor or enforce compliance by Dealer or Counterparty with any obligation hereunder, including without limitation, any obligations to maintain collateral. Each of Dealer and Counterparty agrees to proceed solely against the other to collect or recover any securities or monies owing to it in connection with or as a result of the Transaction. Credit Suisse Securities (USA) LLC shall otherwise have no liability in respect of the Transaction, except for its gross negligence or willful misconduct in performing its duties as Agent.

20

Dealer is not a member of the SIPC (Securities Investor Protection Corporation).

Dealer represents that it is an “OTC derivatives dealer” as such term is defined in the Exchange Act and is an affiliate of a broker-dealer that is registered with and fully-regulated by the SEC, Credit Suisse Securities (USA) LLC.

The date and time of the Transaction evidenced hereby will be furnished by the Agent to Dealer and Counterparty upon written request.

The Agent will furnish to Counterparty upon written request a statement as to the source and amount of any remuneration received or to be received by the Agent in connection with the Transaction evidenced hereby.

| (h) | Submission to Jurisdiction. THE PARTIES HERETO IRREVOCABLY SUBMIT TO THE EXCLUSIVE JURISDICTION OF THE COURTS OF THE STATE OF NEW YORK AND THE UNITED STATES COURT FOR THE SOUTHERN DISTRICT OF NEW YORK IN CONNECTION WITH ALL MATTERS RELATING HERETO AND WAIVE ANY OBJECTION TO THE LAYING OF VENUE IN, AND ANY CLAIM OF INCONVENIENT FORUM WITH RESPECT TO, THESE COURTS.

| (i) | Additional Termination Events.

| (i) | 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, 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.

| (ii) | Promptly (and in any event within five Scheduled Trading Days) following any (i) repurchase (which, for the avoidance of doubt, includes any exchange transaction) and cancellation of Convertible Notes, including without limitation pursuant to Article 15 of the Indenture in connection with a “Fundamental Change” (as defined in the Indenture) or (ii) any Convertible Notes are redeemed (whether pursuant to Section 16.01 of the Indenture or otherwise) by Counterparty and are no longer outstanding under the Indenture, (such event, a “Repurchase Event”), Counterparty may notify Dealer in writing of such Repurchase Event and the number of Convertible Notes subject to such Repurchase Event (any such notice, a “Repurchase Notice”). Notwithstanding anything to the contrary in this Confirmation, the receipt by Dealer from Counterparty of (x) any Repurchase Notice, within the applicable time period set forth in the preceding sentence, and (y) a written representation and warranty by Counterparty that, as of the date of such Repurchase Notice, Counterparty is not in possession of any material non-public information regarding Counterparty or the Shares, shall constitute an Additional Termination Event as provided in this paragraph. Upon receipt of any such Repurchase Notice and the related written representation and warranty, Dealer shall promptly designate an Exchange Business Day following receipt of such Repurchase Notice (which Exchange Business Day shall be on or as promptly as reasonably practicable after the related repurchase settlement date for the relevant Repurchase Event) as an Early Termination Date with respect to the portion of this Transaction corresponding to a number of Options (the “Repurchase Options”) equal to the lesser of (A) the number of such Convertible Notes specified in such Repurchase Notice minus the number of “Repurchase Options” (as defined in the Base Call Option Confirmation), if any, that relate to such Convertible Notes divided by the Applicable Percentage 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 Repurchase Options. Any payment hereunder with respect to such termination 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 this Transaction and a Number of Options equal to the number of Repurchase Options, (2) Counterparty were the sole Affected Party with respect to such Additional Termination Event, (3) no adjustment to the “Conversion Rate” (as defined in the Indenture) for the Convertible Notes has occurred pursuant to any Excluded Provision, (4) the corresponding Convertible Notes remaining outstanding as if the circumstances related to the Repurchase Event had not occurred, (5) the relevant Repurchase Event and any conversions, adjustments, agreements, payments, deliveries or acquisitions by or on behalf of Counterparty leading thereto had not occurred, and (6) the terminated portion of the Transaction were the sole Affected Transaction.

21

| (j) | Amendments to Equity Definitions.

| (i) | Section 12.6(a)(ii) of the Equity Definitions is hereby amended by (1) deleting from the fourth line thereof the word “or” after the word “official” and inserting a comma therefor, and (2) deleting the semi-colon at the end of subsection (B) thereof and inserting the following words therefor “or (C) 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.”

| (ii) | Section 12.9(b)(i) of the Equity Definitions is hereby amended by (1) replacing “either party may elect” with “Dealer may elect” and (2) replacing “notice to the other party” with “notice to Counterparty” in the first sentence of such section.

| (k) | No Setoff. Each party waives any and all rights it may have to set off obligations arising under the Agreement and the Transaction against other obligations between the parties, whether arising under any other agreement, applicable 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 all holders of Shares consists solely of cash, (ii) 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 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(a)(v) as of the date of such election and (c) Dealer agrees, in its sole 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.

22

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 good faith and in a commercially reasonable manner 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 Price the Calculation Agent may consider the purchase price paid in connection with the purchase of Share Termination Delivery Property.
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 the Share Termination Alternative is applicable to the Transaction.

23

| (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 (“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 customary form and substance reasonably satisfactory to Dealer, substantially in the form of an underwriting agreement for a registered secondary offering of equity securities of comparable size of companies of comparable size, maturity and line of business; 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 private placement purchase agreements customary for private placements of equity securities of comparable size of companies of comparable size, maturity and line of business, in customary form and substance that is commercially reasonable and 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 commercially 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 Relevant Price on such Exchange Business Days, and in the amounts, 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 a commercially reasonable manner, 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 determines, in its reasonable discretion, that such action is reasonably necessary or appropriate to preserve Dealer’s commercially reasonable hedging or hedge unwind activity hereunder in light of existing liquidity conditions or to enable Dealer to effect purchases of Shares 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 in no event shall Dealer have the right to so postpone or add any Valid Day(s) or any such other date beyond the 30th Valid Day immediately following the last Valid Day of the relevant Settlement Averaging Period (determined without regard to this Section 9(p)).

24

| (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 actually received by holders of Shares (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;

| (ii) | promptly following any adjustment to the Convertible Notes in connection with any Potential Adjustment Event, Merger Event or Tender Offer, Counterparty shall give Dealer written notice of the details of such adjustment; and

| (iii) | concurrently with any issuance by Counterparty of a Redemption Notice with respect to the Convertible Notes in accordance with Section 16.02 of the Indenture, Counterparty shall notify Dealer of such Redemption Notice, the anticipated Redemption Date and the number of Convertible Notes subject thereto.

| (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 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.

25

| (v) | Early Unwind. In the event the sale of the “Option Securities” (as defined in the Purchase Agreement) is not consummated with the Initial Purchasers 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) | Determinations; Adjustments. All calculations, adjustments and determinations made by Dealer hereunder, whether as Calculation Agent, as Determining Party or following the occurrence of an Early Termination Date, shall be made in good faith and in a commercially reasonable manner. Following any determination, adjustment or calculation by Dealer hereunder (including, without limitation, in its capacity as Calculation Agent), Dealer will provide to Counterparty by email to the email address provided by Counterparty in such written request a report (in a commonly used file format for the storage and manipulation of financial data) displaying in reasonable detail the basis for such calculation; provided, however, that in no event will Dealer be obligated to share with Counterparty any proprietary or confidential data or information or any proprietary or confidential models used by it. For the avoidance of doubt, whenever the Calculation Agent or Determining Party (as the case may be) is called upon to make an adjustment pursuant to the terms of this Confirmation or the Equity Definitions (other than any adjustment required to be made by reference to the terms of the Convertible Notes or the Indenture) to take into account the effect of an event, the Calculation Agent or Determining Party (as the case may be) shall make such adjustment by reference to the effect of such event on the Hedging Party, assuming that the Hedging Party maintains a commercially reasonable hedge position.

| (y) | Tax Matters.

| (i) | Payee Representations:

| For | the purpose of Section 3(f) of the Agreement, Counterparty makes the following representation to Dealer:

| Counterparty is a corporation and a U.S. person (as that term is defined in Section 7701(a)(30) of the Code and used in Section 1.1441-4(a)(3)(ii) of the United States Treasury Regulations) for U.S. federal income tax purposes.

| For | the purpose of Section 3(f) of the Agreement, Dealer makes the following representation to Counterparty:

| Dealer is a disregarded entity for U.S. federal income tax purposes that is wholly owned by Credit Suisse Capital Holdings, Inc., which is a “U.S. person” (as that term is used in Section 1.1441-4(a)(3)(ii) of United States Treasury Regulations) for U.S. federal income tax purposes and an exempt recipient under Section 1.6049-4(c)(1)(ii) of the United States Treasury Regulations.

26

Re: | Additional 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 JPMorgan Chase Bank, National Association, New York Branch (“Dealer”) and Enphase Energy, 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. This Confirmation shall replace any previous agreements and serve as the final documentation for the Transaction.

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 Offering Memorandum dated February 24, 2021 (the “Offering Memorandum”) relating to the Convertible Senior Notes due 2026 (as originally issued by Counterparty, 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 575,000,000 (as increased by an aggregate principal amount of USD 57,500,000 pursuant to the exercise by the Initial Purchasers (as defined herein) of their over-allotment option to purchase additional Convertible Notes pursuant to the Purchase Agreement (as defined herein)) pursuant to an Indenture dated March 1, 2021 between Counterparty and U.S. Bank National Association, as trustee (the “Indenture”). In the event of any inconsistency between the terms defined in the Offering Memorandum, the Indenture and this Confirmation, this Confirmation shall govern. The parties acknowledge that this Confirmation is entered into on the date hereof with the understanding that (i) definitions set forth in the Indenture which are also defined herein by reference to the Indenture and (ii) sections of the Indenture that are referred to herein will conform to the descriptions thereof in the Offering Memorandum. If any such definitions in the Indenture or any such sections of the Indenture differ from the descriptions thereof in the Offering Memorandum, the descriptions thereof in the Offering Memorandum will govern for purposes of this Confirmation. 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 as in effect on the date of its execution, and if the Indenture is amended following such date (other than any amendment pursuant to Section 10.01(m) of the Indenture that, as determined by the Calculation Agent, conforms the Indenture to the description of Convertible Notes in the Offering Memorandum), any such amendment will be disregarded for purposes of this Confirmation 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) and (ii) the election that the “Cross Default” provisions of Section 5(a)(vi) of the Agreement shall apply to Dealer, with a “Threshold Amount” of 3% of shareholders’ equity of Dealer (provided that (a) the phrase “, or becoming capable at such time of being declared,” shall be deleted from clause (1) of such Section 5(a)(vi) of the Agreement, (b) “Specified Indebtedness” shall have 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.”)) on the Trade Date.

|  |  | Dealer will pay cash in lieu of delivering any fractional Shares to be delivered with respect to any Net Share Settlement Share Amount valued at the Relevant Price for the last Valid Day of the Settlement Averaging Period.

6

|  | Combination Settlement: | If Combination Settlement is applicable to any Option exercised or deemed exercised hereunder, Dealer will pay or deliver, as the case may be, to Counterparty, on the relevant Settlement Date for each such Option:

|  | (i) | cash (the “Combination Settlement Cash Amount”) equal to the sum, for each Valid Day during the Settlement Averaging Period for such Option, of (A) an amount (the “Daily Combination Settlement Cash Amount”) equal to the lesser of (1) the product of (x) the Applicable Percentage and (y) the Specified Cash Amount minus USD 1,000 and (2) the Daily Option Value, divided by (B) the number of Valid Days in the Settlement Averaging Period; provided that if the calculation in clause (A) above results in zero or a negative number for any Valid Day, the Daily Combination Settlement Cash Amount for such Valid Day shall be deemed to be zero; and

|  | (ii) | Shares (the “Combination Settlement Share Amount”) equal to the sum, for each Valid Day during the Settlement Averaging Period for such Option, of a number of Shares for such Valid Day (the “Daily Combination Settlement Share Amount”) equal to (A) (1) the Daily Option Value on such Valid Day minus the Daily Combination Settlement Cash Amount for such Valid Day, divided by (2) the Relevant Price on such Valid Day, divided by (B) the number of Valid Days in the Settlement Averaging Period; provided that if the calculation in sub-clause (A)(1) above results in zero or a negative number for any Valid Day, the Daily Combination Settlement Share Amount for such Valid Day shall be deemed to be zero;

|  |  | provided that in no event shall the sum of (x) the Combination Settlement Cash Amount for any Option, and (y) the Combination Settlement Share Amount for such Option, multiplied by the Applicable Limit Price on the Settlement Date for such Option, exceed the Applicable Limit for such Option.
|  |  | Dealer will pay cash in lieu of delivering any fractional Shares to be delivered with respect to any Combination Settlement Share Amount valued at the Relevant Price for the last Valid Day of the Settlement Averaging Period.
|  | Cash Settlement: | If Cash Settlement is applicable to any Option exercised or deemed exercised hereunder, in lieu of Section 8.1 of the Equity Definitions, Dealer will pay to Counterparty, on the relevant Settlement Date for each such Option, an amount of cash (the “Cash Settlement Amount”) equal to the sum, for each Valid Day during the Settlement Averaging Period for such Option, of (i) the Daily Option Value for such Valid Day, divided by (ii) the number of Valid Days in the Settlement Averaging Period; provided that in no event shall the Cash Settlement Amount exceed the Applicable Limit for such Option.

8. | Representations and Warranties of Counterparty.

| (a) | Representations and Warranties of Counterparty. Each of the representations and warranties of Counterparty set forth in Section 2 of the Purchase Agreement (the “Purchase Agreement”), dated as of February 24, 2021, among Counterparty and BofA Securities, Inc. and Barclays Capital Inc., as representatives of the initial purchasers party thereto (the “Initial Purchasers”), are true and correct and are hereby deemed to be repeated to Dealer as if set forth herein. Counterparty hereby further represents and warrants to Dealer on the date hereof and on and as of the Premium Payment Date that:

| (i) | Counterparty has all necessary corporate power and authority to execute, deliver and perform its obligations in respect of the Transaction; such execution, delivery and performance have been duly authorized by all necessary corporate action on Counterparty’s part; and this Confirmation has been duly and validly executed and delivered by Counterparty and constitutes its valid and binding obligation, enforceable against Counterparty in accordance with its terms, subject to applicable bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and similar laws affecting creditors’ rights and remedies generally, and subject, as to enforceability, to general principles of equity, including principles of commercial reasonableness, good faith and fair dealing (regardless of whether enforcement is sought in a proceeding at law or in equity) and except that rights to indemnification and contribution hereunder may be limited by federal or state securities laws or public policy relating thereto.

| (ii) | Neither the execution and delivery of this Confirmation nor the incurrence or performance of obligations of Counterparty hereunder will conflict with or result in a breach of (A) the certificate of incorporation or by-laws (or any equivalent documents) of Counterparty, or (B) any applicable law or regulation, or any order, writ, injunction or decree of any court or governmental authority or agency, or (C) any agreement or instrument to which Counterparty or any of its subsidiaries is a party or by which Counterparty or any of its subsidiaries is bound or to which Counterparty or any of its subsidiaries is subject, or constitute a default under, or result in the creation of any lien under, any such agreement or instrument, except for any such conflicts, breaches, defaults or lien creations in the cases of clause (C) above that would not adversely affect the ability of Counterparty to fulfill its obligations under this Transaction.

| (iii) | No consent, approval, authorization, or order of, or filing with, any governmental agency or body or any court is required in connection with the execution, delivery or performance by Counterparty of this Confirmation, except such as have been obtained or made and such as may be required under the Securities Act or state securities laws.

| (iv) | Counterparty is not and, after consummation of the transactions contemplated hereby, will not be required to register as an “investment company” as such term is defined in the Investment Company Act of 1940, as amended.

15

| (v) | Counterparty is in compliance, in all material respects, with its periodic reporting obligations under the Exchange Act.

| (vi) | Counterparty (A) is capable of evaluating investment risks independently, both in general and with regard to all transactions and investment strategies involving a security or securities; (B) will exercise independent judgment in evaluating the recommendations of any broker-dealer or its associated persons, unless it has otherwise notified the broker-dealer in writing; and (C) has total assets of at least $50 million.

| (vii) | Counterparty acknowledges that the Transaction may constitute a purchase of its equity securities. Counterparty further acknowledges that, pursuant to the provisions of the Coronavirus Aid, Relief and Economic Security Act (the “Cares Act”), the Counterparty will be required to agree to certain time-bound restrictions on its ability to purchase its equity securities if it receives loans, loan guarantees or direct loans (as that term is defined in the Cares Act) under section 4003(b) of the Cares Act. Counterparty further acknowledges that it may be required to agree to certain time-bound restrictions on its ability to purchase its equity securities if it receives loans, loan guarantees or direct loans (as that term is defined in the Cares Act) under programs or facilities established by the Board of Governors of the Federal Reserve System for the purpose of providing liquidity to the financial system. Accordingly, Counterparty represents and warrants that neither it nor any of its subsidiaries has applied, and throughout the term of the Transaction neither it nor any of its subsidiaries shall apply, for a loan, loan guarantee, direct loan (as that term is defined in the Cares Act) or other investment, or to receive any financial assistance or relief (howsoever defined) under any program or facility established in any jurisdiction that (a) is established under applicable law, including without limitation the Cares Act and the Federal Reserve Act, as amended, and (b) requires, as a condition of such loan, loan guarantee, direct loan (as that term is defined in the Cares Act), investment, financial assistance or relief, that the Counterparty agree, attest, certify or warrant that neither it nor any of its subsidiaries has, as of the date specified in such condition, repurchased, or will repurchase, any equity security of Counterparty. Counterparty further represents and warrants that the Premium is not being paid, in whole or in part, directly or indirectly, with funds received under or pursuant to any program or facility established in any jurisdiction, including the U.S. Small Business Administration’s “Paycheck Protection Program”, that (a) is established under applicable law (whether in existence as of the Trade Date or subsequently enacted, adopted or amended), including without limitation the CARES Act and the Federal Reserve Act, as amended, and (b) requires under such applicable law (or any regulation, guidance, interpretation or other pronouncement of a governmental authority with jurisdiction for such program or facility) that such funds be used for specified or enumerated purposes that do not include the purchase of the Transaction (either by specific reference to the Transaction or by general reference to transactions with the attributes of the Transaction in all relevant respects).

| (b) | Each of Dealer and Counterparty agrees and represents that it is an “eligible contract participant” (as such term is defined in Section 1a(18) of the Commodity Exchange Act, as amended (the “CEA”), other than a person that is an eligible contract participant under Section 1a(18)(C) of the CEA).

9. | Other Provisions.

| (a) | Opinions. Counterparty shall deliver to Dealer an opinion of counsel, dated as of the Trade Date, with respect to (i) the matters set forth in Section 8(a)(ii)(B) and Section 8(a)(iii) of this Confirmation to the knowledge of counsel, (ii) due incorporation, existence and good standing of Counterparty in Delaware, (iii) the due authorization, execution and delivery of this Confirmation, and, (iv) in respect of the execution, delivery and performance of this Confirmation, the absence of any conflict with or breach of any material agreement required to be filed as an exhibit to Counterparty’s Annual Report on Form 10-K, Counterparty’s certificate of incorporation or Counterparty’s by-laws. 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.

16

| (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 101.3 million (in the case of the first such notice) or (ii) thereafter more than 18.0 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 losses (including losses relating to Dealer’s hedging activities as a consequence of becoming, or of the risk of becoming, a Section 16 “insider”, including without limitation, any forbearance from hedging activities or cessation of hedging activities and any losses in connection therewith with respect to the Transaction), claims, damages, judgments, liabilities and expenses (including reasonable attorney’s fees), joint or several, which an Indemnified Person may become subject to, 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 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 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. If the indemnification provided for in this paragraph is unavailable to an Indemnified Person or insufficient in respect of any 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.

| (c) | Regulation M. Counterparty is not on the Trade Date engaged in a distribution, as such term is used in Regulation M under the Securities Exchange Act of 1934, as amended (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 manipulate the price of the Shares (or any security convertible into or exchangeable for the Shares) in violation of the Exchange Act.

17

| (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 (the “Code”);

| (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 commercially reasonable costs and expenses, including commercially reasonable counsel fees, incurred by Dealer in connection with such transfer or assignment.

18

| (ii) | Dealer may, without Counterparty’s consent, transfer or assign (such transfer or assignment, a “Transfer”) 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 Transfer, 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) with Counterparty’s consent (not to be unreasonably withheld or delayed) 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 rate such third party, 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 shall be a “dealer in securities” within the meaning of Section 475(c)(1) of the Code or (y) the Transfer will not result in a deemed exchange by Counterparty within the meaning of Section 1001 of the Code; and provided further that Dealer shall provide notice to Counterparty following any such Transfer. If at any time at which (A) the Section 16 Percentage exceeds 8.0%, (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). 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 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 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.

19

| (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 (each, a “Dealer Designated Affiliate”) 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 under this Confirmation to the extent such Dealer Designated Affiliate fully performs the obligations designated by Dealer to such Dealer Designated Affiliate under this Section 9(e)(iii).

| (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 that would be customarily applicable to transactions of this type by the dealers in this market as determined by the Calculation Agent, 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 (the first of which will be such Nominal Settlement Date and the last of which will be no later than the twentieth (20th) Exchange Business Day following 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.

| (g) | [Reserved]

| (h) | Submission to Jurisdiction. THE PARTIES HERETO IRREVOCABLY SUBMIT TO THE EXCLUSIVE JURISDICTION OF THE COURTS OF THE STATE OF NEW YORK AND THE UNITED STATES COURT FOR THE SOUTHERN DISTRICT OF NEW YORK IN CONNECTION WITH ALL MATTERS RELATING HERETO AND WAIVE ANY OBJECTION TO THE LAYING OF VENUE IN, AND ANY CLAIM OF INCONVENIENT FORUM WITH RESPECT TO, THESE COURTS.

| (i) | Additional Termination Events.

| (i) | 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, 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.

20

| (ii) | Promptly (and in any event within five Scheduled Trading Days) following any (i) repurchase (which, for the avoidance of doubt, includes any exchange transaction) and cancellation of Convertible Notes, including without limitation pursuant to Article 15 of the Indenture in connection with a “Fundamental Change” (as defined in the Indenture) or (ii) any Convertible Notes are redeemed (whether pursuant to Section 16.01 of the Indenture or otherwise) by Counterparty and are no longer outstanding under the Indenture, (such event, a “Repurchase Event”), Counterparty may notify Dealer in writing of such Repurchase Event and the number of Convertible Notes subject to such Repurchase Event (any such notice, a “Repurchase Notice”). Notwithstanding anything to the contrary in this Confirmation, the receipt by Dealer from Counterparty of (x) any Repurchase Notice, within the applicable time period set forth in the preceding sentence, and (y) a written representation and warranty by Counterparty that, as of the date of such Repurchase Notice, Counterparty is not in possession of any material non-public information regarding Counterparty or the Shares, shall constitute an Additional Termination Event as provided in this paragraph. Upon receipt of any such Repurchase Notice and the related written representation and warranty, Dealer shall promptly designate an Exchange Business Day following receipt of such Repurchase Notice (which Exchange Business Day shall be on or as promptly as reasonably practicable after the related repurchase settlement date for the relevant Repurchase Event) as an Early Termination Date with respect to the portion of this Transaction corresponding to a number of Options (the “Repurchase Options”) equal to the lesser of (A) the number of such Convertible Notes specified in such Repurchase Notice minus the number of “Repurchase Options” (as defined in the Base Call Option Confirmation), if any, that relate to such Convertible Notes divided by the Applicable Percentage 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 Repurchase Options. Any payment hereunder with respect to such termination 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 this Transaction and a Number of Options equal to the number of Repurchase Options, (2) Counterparty were the sole Affected Party with respect to such Additional Termination Event, (3) no adjustment to the “Conversion Rate” (as defined in the Indenture) for the Convertible Notes has occurred pursuant to any Excluded Provision, (4) the corresponding Convertible Notes remaining outstanding as if the circumstances related to the Repurchase Event had not occurred, (5) the relevant Repurchase Event and any conversions, adjustments, agreements, payments, deliveries or acquisitions by or on behalf of Counterparty leading thereto had not occurred, and (6) the terminated portion of the Transaction were the sole Affected Transaction.

| (j) | Amendments to Equity Definitions.

| (i) | Section 12.6(a)(ii) of the Equity Definitions is hereby amended by (1) deleting from the fourth line thereof the word “or” after the word “official” and inserting a comma therefor, and (2) deleting the semi-colon at the end of subsection (B) thereof and inserting the following words therefor “or (C) 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.”

| (ii) | Section 12.9(b)(i) of the Equity Definitions is hereby amended by (1) replacing “either party may elect” with “Dealer may elect” and (2) replacing “notice to the other party” with “notice to Counterparty” in the first sentence of such section.

| (k) | No Setoff. Each party waives any and all rights it may have to set off obligations arising under the Agreement and the Transaction against other obligations between the parties, whether arising under any other agreement, applicable law or otherwise.

21

| (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 all holders of Shares consists solely of cash, (ii) 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 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(a)(v) as of the date of such election and (c) Dealer agrees, in its sole 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 good faith and in a commercially reasonable manner 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 Price the Calculation Agent may consider the purchase price paid in connection with the purchase of Share Termination Delivery Property.
| 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.

22

| 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 the Share Termination Alternative is applicable to the Transaction.

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 (“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 customary form and substance reasonably satisfactory to Dealer, substantially in the form of an underwriting agreement for a registered secondary offering of equity securities of comparable size of companies of comparable size, maturity and line of business; 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 private placement purchase agreements customary for private placements of equity securities of comparable size of companies of comparable size, maturity and line of business, in customary form and substance that is commercially reasonable and 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 commercially 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 Relevant Price on such Exchange Business Days, and in the amounts, 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.

23

| (p) | Right to Extend. Dealer may postpone or add, in a commercially reasonable manner, 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 determines, in its reasonable discretion, that such action is reasonably necessary or appropriate to preserve Dealer’s commercially reasonable hedging or hedge unwind activity hereunder in light of existing liquidity conditions or to enable Dealer to effect purchases of Shares 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 in no event shall Dealer have the right to so postpone or add any Valid Day(s) or any such other date beyond the 30th Valid Day immediately following the last Valid Day of the relevant Settlement Averaging Period (determined without regard to this Section 9(p)).

| (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.

| (ii) | promptly following any adjustment to the Convertible Notes in connection with any Potential Adjustment Event, Merger Event or Tender Offer, Counterparty shall give Dealer written notice of the details of such adjustment; and

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)).

24

| (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 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 “Option Securities” (as defined in the Purchase Agreement) is not consummated with the Initial Purchasers 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) | Determinations; Adjustments. All calculations, adjustments and determinations made by Dealer hereunder, whether as Calculation Agent, as Determining Party or following the occurrence of an Early Termination Date, shall be made in good faith and in a commercially reasonable manner. Following any determination, adjustment or calculation by Dealer hereunder (including, without limitation, in its capacity as Calculation Agent), Dealer will provide to Counterparty by email to the email address provided by Counterparty in such written request a report (in a commonly used file format for the storage and manipulation of financial data) displaying in reasonable detail the basis for such calculation; provided, however, that in no event will Dealer be obligated to share with Counterparty any proprietary or confidential data or information or any proprietary or confidential models used by it. For the avoidance of doubt, whenever the Calculation Agent or Determining Party (as the case may be) is called upon to make an adjustment pursuant to the terms of this Confirmation or the Equity Definitions (other than any adjustment required to be made by reference to the terms of the Convertible Notes or the Indenture) to take into account the effect of an event, the Calculation Agent or Determining Party (as the case may be) shall make such adjustment by reference to the effect of such event on the Hedging Party, assuming that the Hedging Party maintains a commercially reasonable hedge position.

The purpose of this letter agreement (this “Confirmation”) is to confirm the terms and conditions of the call option transaction entered into between Mizuho Markets Americas LLC (“MMA”) (with Mizuho Securities USA LLC (“MSUSA”) acting as agent) (“Dealer”) and Enphase Energy, 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. This Confirmation shall replace any previous agreements and serve as the final documentation for the Transaction. MMA is acting as principal in its capacity as Dealer hereunder and MSUSA, its affiliate, is acting as agent for MMA, in its capacity as Dealer hereunder, and Counterparty hereunder. This Master Confirmation and each Supplemental Confirmation is a confirmation for purposes of Rule 10b-10 promulgated under the Exchange Act (as defined below). MMA is not a member of the Securities Investor Protection Corporation.

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 Offering Memorandum dated February 24, 2021 (the “Offering Memorandum”) relating to the Convertible Senior Notes due 2026 (as originally issued by Counterparty, 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 575,000,000 (as increased by an aggregate principal amount of USD 57,500,000 pursuant to the exercise by the Initial Purchasers (as defined herein) of their over-allotment option to purchase additional Convertible Notes pursuant to the Purchase Agreement (as defined herein)) pursuant to an Indenture dated March 1, 2021 between Counterparty and U.S. Bank National Association, as trustee (the “Indenture”). In the event of any inconsistency between the terms defined in the Offering Memorandum, the Indenture and this Confirmation, this Confirmation shall govern. The parties acknowledge that this Confirmation is entered into on the date hereof with the understanding that (i) definitions set forth in the Indenture which are also defined herein by reference to the Indenture and (ii) sections of the Indenture that are referred to herein will conform to the descriptions thereof in the Offering Memorandum. If any such definitions in the Indenture or any such sections of the Indenture differ from the descriptions thereof in the Offering Memorandum, the descriptions thereof in the Offering Memorandum will govern for purposes of this Confirmation. 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 as in effect on the date of its execution, and if the Indenture is amended following such date (other than any amendment pursuant to Section 10.01(m) of the Indenture that, as determined by the Calculation Agent, conforms the Indenture to the description of Convertible Notes in the Offering Memorandum), any such amendment will be disregarded for purposes of this Confirmation 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.

The parties hereto agree and acknowledge that if the Trustee or any other agent authorized by Counterparty and previously identified to Dealer by Counterparty in writing on behalf of Counterparty provides notice to Dealer as provided for in the second immediately preceding sentence, Dealer shall be entitled to rely on the accuracy of such notice without any independent investigation.

4

Valuation Time: | At the close of trading of the regular trading session on the Exchange; provided that if the principal trading session is extended, the Calculation Agent shall determine the Valuation Time in good faith and in a commercially reasonable manner.

| “‘Market Disruption Event’ means, in respect of a Share, (i) a failure by the primary United States national or regional securities exchange or market on which the Shares are listed or admitted for trading to open for trading during its regular trading session or (ii) the occurrence or existence prior to 1:00 p.m. (New York City time) on any Scheduled Valid Day for the Shares for more than one half-hour period in the aggregate during regular trading hours of any suspension or limitation imposed on trading (by reason of movements in price exceeding limits permitted by the relevant stock exchange or otherwise) in the Shares or in any options contracts or futures contracts relating to the Shares.”

Settlement Terms.

Settlement Method: | For any Option, Net Share Settlement; provided that if the Relevant Settlement Method set forth below for such Option is not Net Share Settlement, then the Settlement Method for such Option shall be such Relevant Settlement Method, but only if Counterparty, or the Trustee (or other agent authorized by Counterparty and previously identified to Dealer by Counterparty in writing) on behalf of Counterparty, shall have notified Dealer of the Relevant Settlement Method in the Notice of Exercise or Notice of Final Settlement Method, as applicable, for such Option. The parties hereto agree and acknowledge that if the Trustee or any other agent authorized by Counterparty and previously identified to Dealer by Counterparty in writing on behalf of Counterparty provides notice to Dealer as provided for in the proviso to the immediately preceding sentence, Dealer shall be entitled to rely on the accuracy of such notice without any independent investigation.

5

Relevant Settlement Method: | In respect of any Option:
| (i) if Counterparty has elected to settle its conversion obligations in respect of the related Convertible Note (A) entirely in Shares pursuant to Section 14.02(iv)(A) of the Indenture (together with cash in lieu of fractional Shares) (such settlement method, “Settlement in Shares”), (B) in a combination of cash and Shares pursuant to Section 14.04(iv)(C) of the Indenture with a Specified Cash Amount less than USD 1,000 or (C) in a combination of cash and Shares pursuant to Section 14.04(iv)(C) of the Indenture with a Specified Cash Amount equal to USD 1,000, then, in each case, the Relevant Settlement Method for such Option shall be Net Share Settlement;
| (ii) if Counterparty has elected to settle its conversion obligations in respect of the related Convertible Note in a combination of cash and Shares pursuant to Section 14.04(iv)(C) of the Indenture with a Specified Cash Amount greater than USD 1,000, then the Relevant Settlement Method for such Option shall be Combination Settlement; and
| (iii) if Counterparty has elected to settle its conversion obligations in respect of the related Convertible Note entirely in cash pursuant to Section 14.04(iv)(B) of the Indenture (such settlement method, “Settlement in Cash”), then the Relevant Settlement Method for such Option shall be Cash Settlement.
Net Share Settlement: | If Net Share Settlement is applicable to any Option exercised or deemed exercised hereunder, Dealer will deliver to Counterparty, on the relevant Settlement Date for each such Option, a number of Shares (the “Net Share Settlement Amount”) equal to the sum, for each Valid Day during the Settlement Averaging Period for each such Option, of (i) (a) the Daily Option Value for such Valid Day, divided by (b) the Relevant Price on such Valid Day, divided by (ii) the number of Valid Days in the Settlement Averaging Period; provided that in no event shall the Net Share Settlement Amount for any Option exceed a number of Shares equal to the Applicable Limit for such Option, divided by the Applicable Limit Price on the Settlement Date for such Option.

6

| Dealer will pay cash in lieu of delivering any fractional Shares to be delivered with respect to any Net Share Settlement Share Amount valued at the Relevant Price for the last Valid Day of the Settlement Averaging Period.
Combination Settlement: | If Combination Settlement is applicable to any Option exercised or deemed exercised hereunder, Dealer will pay or deliver, as the case may be, to Counterparty, on the relevant Settlement Date for each such Option:

| (i) | cash (the “Combination Settlement Cash Amount”) equal to the sum, for each Valid Day during the Settlement Averaging Period for such Option, of (A) an amount (the “Daily Combination Settlement Cash Amount”) equal to the lesser of (1) the product of (x) the Applicable Percentage and (y) the Specified Cash Amount minus USD 1,000 and (2) the Daily Option Value, divided by (B) the number of Valid Days in the Settlement Averaging Period; provided that if the calculation in clause (A) above results in zero or a negative number for any Valid Day, the Daily Combination Settlement Cash Amount for such Valid Day shall be deemed to be zero; and

| (ii) | Shares (the “Combination Settlement Share Amount”) equal to the sum, for each Valid Day during the Settlement Averaging Period for such Option, of a number of Shares for such Valid Day (the “Daily Combination Settlement Share Amount”) equal to (A) (1) the Daily Option Value on such Valid Day minus the Daily Combination Settlement Cash Amount for such Valid Day, divided by (2) the Relevant Price on such Valid Day, divided by (B) the number of Valid Days in the Settlement Averaging Period; provided that if the calculation in sub-clause (A)(1) above results in zero or a negative number for any Valid Day, the Daily Combination Settlement Share Amount for such Valid Day shall be deemed to be zero;

| provided that in no event shall the sum of (x) the Combination Settlement Cash Amount for any Option, and (y) the Combination Settlement Share Amount for such Option, multiplied by the Applicable Limit Price on the Settlement Date for such Option, exceed the Applicable Limit for such Option.
| Dealer will pay cash in lieu of delivering any fractional Shares to be delivered with respect to any Combination Settlement Share Amount valued at the Relevant Price for the last Valid Day of the Settlement Averaging Period.
Cash Settlement: | If Cash Settlement is applicable to any Option exercised or deemed exercised hereunder, in lieu of Section 8.1 of the Equity Definitions, Dealer will pay to Counterparty, on the relevant Settlement Date for each such Option, an amount of cash (the “Cash Settlement Amount”) equal to the sum, for each Valid Day during the Settlement Averaging Period for such Option, of (i) the Daily Option Value for such Valid Day, divided by (ii) the number of Valid Days in the Settlement Averaging Period; provided that in no event shall the Cash Settlement Amount exceed the Applicable Limit for such Option.

7

Daily Option Value: | For any Valid Day, an amount equal to (i) the Option Entitlement on such Valid Day, multiplied by (ii) the Relevant Price on such Valid Day less the Strike Price on such Valid Day; provided that if the calculation contained in clause (ii) above results in a negative number, the Daily Option Value for such Valid Day shall be deemed to be zero. In no event will the Daily Option Value be less than zero.
Make-Whole Adjustment: | Notwithstanding anything to the contrary herein, in respect of any exercise of Options relating to a conversion of Convertible Notes for which additional Shares will be added to the “Conversion Rate” (as defined in the Indenture) as determined pursuant to Section 14.03 of the Indenture, the Daily Option Value shall be calculated as if the Option Entitlement included the Applicable Percentage of the number of such additional Shares as determined with reference to the adjustment set forth in such Section 14.03 of the Indenture; provided that if the sum of (i) the product of (a) the number of Shares (if any) deliverable by Dealer to Counterparty per exercised Option and (b) the Applicable Limit Price on the Settlement Date and (ii) the amount of cash (if any) payable by Dealer to Counterparty per exercised Option would otherwise exceed the amount per Option, as determined by the Calculation Agent, that would be payable by Dealer under Section 6 of the Agreement if (x) the relevant Conversion Date were an Early Termination Date resulting from an Additional Termination Event with respect to which the Transaction was the sole Affected Transaction and Counterparty was the sole Affected Party and (y) Section 14.03 of the Indenture were deleted, then each Daily Option Value shall be proportionately reduced to the extent necessary to eliminate such excess.
Applicable Limit: | For any Option, an amount of cash equal to the Applicable Percentage, multiplied by the excess of (i) the aggregate of (A) the amount of cash, if any, paid to the Holder of the related Convertible Note upon conversion of such Convertible Note and (B) the number of Shares, if any, delivered to the Holder of the related Convertible Note upon conversion of such Convertible Note multiplied by the Applicable Limit Price on the Settlement Date for such Option, over (ii) USD 1,000.
Applicable Limit Price: | On any day, the opening price as displayed under the heading “Op” on Bloomberg page ENPH <equity> (or any successor thereto).

8

The Relevant Price will be determined without regard to after-hours trading or any other trading outside of the regular trading session trading hours.
Settlement Averaging Period: | For any Option and regardless of the Settlement Method applicable to such Option:

| (i) | subject to clause (ii), if the related Conversion Date occurs prior to the Averaging Period Threshold Date, the 20 consecutive Valid Days commencing on, and including, the second Valid Day following such Conversion Date; or

| (ii) | with respect to any Convertible Notes called for redemption and converted pursuant to Section 14.01(b)(v) of the Indenture, if the related Conversion Date occurs on or after the date on which Counterparty issues a Redemption Notice with respect to such Convertible Notes in accordance with Section 16.02 of the Indenture and prior to the close of business on the Scheduled Valid Day immediately preceding the related Redemption Date, the 20 consecutive Valid Days commencing on, and including, the 21st Scheduled Valid Day immediately prior to such Redemption Date; and or

9

| (iii) | subject to clause (ii), if the related Conversion Date occurs on or following the Averaging Period Threshold Date, the 20 consecutive Valid Days commencing on, and including, the 21st Scheduled Valid Day immediately prior to the Expiration Date.

Other Applicable Provisions: | The provisions of Sections 9.1(c), 9.8, 9.9 and 9.11 of the Equity Definitions will be applicable, except that all references in such provisions to “Physically-settled” shall be read as references to “Share Settled”. “Share Settled” in relation to any Option means that Net Share Settlement or Combination Settlement is applicable to that Option.
Representation and Agreement: | Notwithstanding anything to the contrary in the Equity Definitions (including, but not limited to, Section 9.11 thereof), the parties acknowledge that (i) any Shares delivered to Counterparty shall be, upon delivery, subject to restrictions and limitations arising from Counterparty’s status as issuer of the Shares under applicable securities laws, (ii) Dealer may deliver any Shares required to be delivered hereunder in certificated form in lieu of delivery through the Clearance System and (iii) any Shares delivered to Counterparty may be “restricted securities” (as defined in Rule 144 under the Securities Act of 1933, as amended (the “Securities Act”)).

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).

| 8. | Representations and Warranties of Counterparty.

| (a) | Representations and Warranties of Counterparty. Each of the representations and warranties of Counterparty set forth in Section 2 of the Purchase Agreement (the “Purchase Agreement”), dated as of February 24, 2021, among Counterparty and BofA Securities, Inc. and Barclays Capital Inc., as representatives of the initial purchasers party thereto (the “Initial Purchasers”), are true and correct and are hereby deemed to be repeated to Dealer as if set forth herein. Counterparty hereby further represents and warrants to Dealer on the date hereof and on and as of the Premium Payment Date that:

| (i) | Counterparty has all necessary corporate power and authority to execute, deliver and perform its obligations in respect of the Transaction; such execution, delivery and performance have been duly authorized by all necessary corporate action on Counterparty’s part; and this Confirmation has been duly and validly executed and delivered by Counterparty and constitutes its valid and binding obligation, enforceable against Counterparty in accordance with its terms, subject to applicable bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and similar laws affecting creditors’ rights and remedies generally, and subject, as to enforceability, to general principles of equity, including principles of commercial reasonableness, good faith and fair dealing (regardless of whether enforcement is sought in a proceeding at law or in equity) and except that rights to indemnification and contribution hereunder may be limited by federal or state securities laws or public policy relating thereto.

15

| (ii) | Neither the execution and delivery of this Confirmation nor the incurrence or performance of obligations of Counterparty hereunder will conflict with or result in a breach of (A) the certificate of incorporation or by-laws (or any equivalent documents) of Counterparty, or (B) any applicable law or regulation, or any order, writ, injunction or decree of any court or governmental authority or agency, or (C) any agreement or instrument to which Counterparty or any of its subsidiaries is a party or by which Counterparty or any of its subsidiaries is bound or to which Counterparty or any of its subsidiaries is subject, or constitute a default under, or result in the creation of any lien under, any such agreement or instrument, except for any such conflicts, breaches, defaults or lien creations in the cases of clause (C) above that would not adversely affect the ability of Counterparty to fulfill its obligations under this Transaction.

| (iii) | No consent, approval, authorization, or order of, or filing with, any governmental agency or body or any court is required in connection with the execution, delivery or performance by Counterparty of this Confirmation, except such as have been obtained or made and such as may be required under the Securities Act or state securities laws.

| (iv) | Counterparty is not and, after consummation of the transactions contemplated hereby, will not be required to register as an “investment company” as such term is defined in the Investment Company Act of 1940, as amended.

| (v) | Counterparty is in compliance, in all material respects, with its periodic reporting obligations under the Exchange Act.

| (vi) | Counterparty (A) is capable of evaluating investment risks independently, both in general and with regard to all transactions and investment strategies involving a security or securities; (B) will exercise independent judgment in evaluating the recommendations of any broker-dealer or its associated persons, unless it has otherwise notified the broker-dealer in writing; and (C) has total assets of at least $50 million.

| (vii) | Counterparty acknowledges that the Transaction may constitute a purchase of its equity securities. Counterparty further acknowledges that, pursuant to the provisions of the Coronavirus Aid, Relief and Economic Security Act (the “Cares Act”), the Counterparty will be required to agree to certain time-bound restrictions on its ability to purchase its equity securities if it receives loans, loan guarantees or direct loans (as that term is defined in the Cares Act) under section 4003(b) of the Cares Act. Counterparty further acknowledges that it may be required to agree to certain time-bound restrictions on its ability to purchase its equity securities if it receives loans, loan guarantees or direct loans (as that term is defined in the Cares Act) under programs or facilities established by the Board of Governors of the Federal Reserve System for the purpose of providing liquidity to the financial system. Accordingly, Counterparty represents and warrants that neither it nor any of its subsidiaries has applied, and throughout the term of the Transaction neither it nor any of its subsidiaries shall apply, for a loan, loan guarantee, direct loan (as that term is defined in the Cares Act) or other investment, or to receive any financial assistance or relief (howsoever defined) under any program or facility established in any jurisdiction that (a) is established under applicable law, including without limitation the Cares Act and the Federal Reserve Act, as amended, and (b) requires, as a condition of such loan, loan guarantee, direct loan (as that term is defined in the Cares Act), investment, financial assistance or relief, that the Counterparty agree, attest, certify or warrant that neither it nor any of its subsidiaries has, as of the date specified in such condition, repurchased, or will repurchase, any equity security of Counterparty. Counterparty further represents and warrants that the Premium is not being paid, in whole or in part, directly or indirectly, with funds received under or pursuant to any program or facility established in any jurisdiction, including the U.S. Small Business Administration’s “Paycheck Protection Program”, that (a) is established under applicable law (whether in existence as of the Trade Date or subsequently enacted, adopted or amended), including without limitation the CARES Act and the Federal Reserve Act, as amended, and (b) requires under such applicable law (or any regulation, guidance, interpretation or other pronouncement of a governmental authority with jurisdiction for such program or facility) that such funds be used for specified or enumerated purposes that do not include the purchase of the Transaction (either by specific reference to the Transaction or by general reference to transactions with the attributes of the Transaction in all relevant respects).

16

| (b) | Each of Dealer and Counterparty agrees and represents that it is an “eligible contract participant” (as such term is defined in Section 1a(18) of the Commodity Exchange Act, as amended (the “CEA”), other than a person that is an eligible contract participant under Section 1a(18)(C) of the CEA).

| 9. | Other Provisions.

| (a) | Opinions.

| (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 101.3 million (in the case of the first such notice) or (ii) thereafter more than 18.0 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 losses (including losses relating to Dealer’s hedging activities as a consequence of becoming, or of the risk of becoming, a Section 16 “insider”, including without limitation, any forbearance from hedging activities or cessation of hedging activities and any losses in connection therewith with respect to the Transaction), claims, damages, judgments, liabilities and expenses (including reasonable attorney’s fees), joint or several, which an Indemnified Person may become subject to, 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 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 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. If the indemnification provided for in this paragraph is unavailable to an Indemnified Person or insufficient in respect of any 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.

17

| (c) | Regulation M. Counterparty is not on the Trade Date engaged in a distribution, as such term is used in Regulation M under the Securities Exchange Act of 1934, as amended (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 manipulate the price of the Shares (or any security convertible into or exchangeable for the Shares) 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 (the “Code”);

| (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;

18

| (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 commercially reasonable costs and expenses, including commercially reasonable counsel fees, incurred by Dealer in connection with such transfer or assignment.

| (ii) | Dealer may, without Counterparty’s consent, transfer or assign (such transfer or assignment, a “Transfer”) 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 Transfer, 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) with Counterparty’s consent (not to be unreasonably withheld or delayed) 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 rate such third party, 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 shall be a “dealer in securities” within the meaning of Section 475(c)(1) of the Code or (y) the Transfer will not result in a deemed exchange by Counterparty within the meaning of Section 1001 of the Code; and provided further that Dealer shall provide notice to Counterparty following any such Transfer. If at any time at which (A) the Section 16 Percentage exceeds 8.0%, (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). 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 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 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.

19

| (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 (each, a “Dealer Designated Affiliate”) 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 under this Confirmation to the extent such Dealer Designated Affiliate fully performs the obligations designated by Dealer to such Dealer Designated Affiliate under this Section 9(e)(iii).

| (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 that would be customarily applicable to transactions of this type by the dealers in this market as determined by the Calculation Agent, 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 (the first of which will be such Nominal Settlement Date and the last of which will be no later than the twentieth (20th) Exchange Business Day following 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.

20

| (g) | Role of Agent.

| (i) | Counterparty understands and agrees that MSUSA will act as agent for both parties with respect to each Transaction and has no obligation, by way of issuance, endorsement, guarantee or otherwise with respect to the performance of either party under any Transaction. MSUSA shall have no responsibility or personal liability to Counterparty arising from any failure by MMA to pay or perform any obligations hereunder or to monitor or enforce compliance by MMA or Counterparty with any obligation hereunder, including, without limitation, any obligations to maintain collateral. MSUSA is so acting solely in its capacity as agent for Counterparty and MMA pursuant to instructions from Counterparty and MMA. Each of MMA and Counterparty agrees to proceed solely against the other to collect or recover any securities or monies owing to it in connection with or as a result of a Transaction.

| (ii) | MSUSA received or will receive other remuneration from MMA in relation to this Master Confirmation and each Transaction hereunder. The amount and source of such other remuneration will be furnished upon written request.

| (h) | Submission to Jurisdiction. THE PARTIES HERETO IRREVOCABLY SUBMIT TO THE EXCLUSIVE JURISDICTION OF THE COURTS OF THE STATE OF NEW YORK AND THE UNITED STATES COURT FOR THE SOUTHERN DISTRICT OF NEW YORK IN CONNECTION WITH ALL MATTERS RELATING HERETO AND WAIVE ANY OBJECTION TO THE LAYING OF VENUE IN, AND ANY CLAIM OF INCONVENIENT FORUM WITH RESPECT TO, THESE COURTS.

| (i) | Additional Termination Events.

| (i) | 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, 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.

| (i) | Promptly (and in any event within five Scheduled Trading Days) following any (i) repurchase (which, for the avoidance of doubt, includes any exchange transaction) and cancellation of Convertible Notes, including without limitation pursuant to Article 15 of the Indenture in connection with a “Fundamental Change” (as defined in the Indenture) or (ii) any Convertible Notes are redeemed (whether pursuant to Section 16.01 of the Indenture or otherwise) by Counterparty and are no longer outstanding under the Indenture, (such event, a “Repurchase Event”), Counterparty may notify Dealer in writing of such Repurchase Event and the number of Convertible Notes subject to such Repurchase Event (any such notice, a “Repurchase Notice”). Notwithstanding anything to the contrary in this Confirmation, the receipt by Dealer from Counterparty of (x) any Repurchase Notice, within the applicable time period set forth in the preceding sentence, and (y) a written representation and warranty by Counterparty that, as of the date of such Repurchase Notice, Counterparty is not in possession of any material non-public information regarding Counterparty or the Shares, shall constitute an Additional Termination Event as provided in this paragraph. Upon receipt of any such Repurchase Notice and the related written representation and warranty, Dealer shall promptly designate an Exchange Business Day following receipt of such Repurchase Notice (which Exchange Business Day shall be on or as promptly as reasonably practicable after the related repurchase settlement date for the relevant Repurchase Event) as an Early Termination Date with respect to the portion of this Transaction corresponding to a number of Options (the “Repurchase Options”) equal to the lesser of (A) the number of such Convertible Notes specified in such Repurchase Notice minus the number of “Repurchase Options” (as defined in the Base Call Option Confirmation), if any, that relate to such Convertible Notes divided by the Applicable Percentage 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 Repurchase Options. Any payment hereunder with respect to such termination 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 this Transaction and a Number of Options equal to the number of Repurchase Options, (2) Counterparty were the sole Affected Party with respect to such Additional Termination Event, (3) no adjustment to the “Conversion Rate” (as defined in the Indenture) for the Convertible Notes has occurred pursuant to any Excluded Provision, (4) the corresponding Convertible Notes remaining outstanding as if the circumstances related to the Repurchase Event had not occurred, (5) the relevant Repurchase Event and any conversions, adjustments, agreements, payments, deliveries or acquisitions by or on behalf of Counterparty leading thereto had not occurred, and (6) the terminated portion of the Transaction were the sole Affected Transaction.

21

| (j) | Amendments to Equity Definitions.

| (i) | Section 12.6(a)(ii) of the Equity Definitions is hereby amended by (1) deleting from the fourth line thereof the word “or” after the word “official” and inserting a comma therefor, and (2) deleting the semi-colon at the end of subsection (B) thereof and inserting the following words therefor “or (C) 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.”

| (ii) | Section 12.9(b)(i) of the Equity Definitions is hereby amended by (1) replacing “either party may elect” with “Dealer may elect” and (2) replacing “notice to the other party” with “notice to Counterparty” in the first sentence of such section.

| (k) | No Setoff. Each party waives any and all rights it may have to set off obligations arising under the Agreement and the Transaction against other obligations between the parties, whether arising under any other agreement, applicable 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 all holders of Shares consists solely of cash, (ii) 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 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(a)(v) as of the date of such election and (c) Dealer agrees, in its sole 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.

22

| 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 good faith and in a commercially reasonable manner 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 Price the Calculation Agent may consider the purchase price paid in connection with the purchase of Share Termination Delivery Property.
| 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 the Share Termination Alternative is applicable to the Transaction.

23

| (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 (“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 customary form and substance reasonably satisfactory to Dealer, substantially in the form of an underwriting agreement for a registered secondary offering of equity securities of comparable size of companies of comparable size, maturity and line of business; 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 private placement purchase agreements customary for private placements of equity securities of comparable size of companies of comparable size, maturity and line of business, in customary form and substance that is commercially reasonable and 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 commercially 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 Relevant Price on such Exchange Business Days, and in the amounts, 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 a commercially reasonable manner, 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 determines, in its reasonable discretion, that such action is reasonably necessary or appropriate to preserve Dealer’s commercially reasonable hedging or hedge unwind activity hereunder in light of existing liquidity conditions or to enable Dealer to effect purchases of Shares 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 in no event shall Dealer have the right to so postpone or add any Valid Day(s) or any such other date beyond the 30th Valid Day immediately following the last Valid Day of the relevant Settlement Averaging Period (determined without regard to this Section 9(p)).

24

| (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 actually received by holders of Shares (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;

| (ii) | promptly following any adjustment to the Convertible Notes in connection with any Potential Adjustment Event, Merger Event or Tender Offer, Counterparty shall give Dealer written notice of the details of such adjustment; and

| (iii) | concurrently with any issuance by Counterparty of a Redemption Notice with respect to the Convertible Notes in accordance with Section 16.02 of the Indenture, Counterparty shall notify Dealer of such Redemption Notice, the anticipated Redemption Date and the number of Convertible Notes subject thereto.

| (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 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.

25

| (v) | Early Unwind. In the event the sale of the “Option Securities” (as defined in the Purchase Agreement) is not consummated with the Initial Purchasers 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) | Determinations; Adjustments. All calculations, adjustments and determinations made by Dealer hereunder, whether as Calculation Agent, as Determining Party or following the occurrence of an Early Termination Date, shall be made in good faith and in a commercially reasonable manner. Following any determination, adjustment or calculation by Dealer hereunder (including, without limitation, in its capacity as Calculation Agent), Dealer will provide to Counterparty by email to the email address provided by Counterparty in such written request a report (in a commonly used file format for the storage and manipulation of financial data) displaying in reasonable detail the basis for such calculation; provided, however, that in no event will Dealer be obligated to share with Counterparty any proprietary or confidential data or information or any proprietary or confidential models used by it. For the avoidance of doubt, whenever the Calculation Agent or Determining Party (as the case may be) is called upon to make an adjustment pursuant to the terms of this Confirmation or the Equity Definitions (other than any adjustment required to be made by reference to the terms of the Convertible Notes or the Indenture) to take into account the effect of an event, the Calculation Agent or Determining Party (as the case may be) shall make such adjustment by reference to the effect of such event on the Hedging Party, assuming that the Hedging Party maintains a commercially reasonable hedge position.

| (y) | Tax Matters.

| (i) | Payee Representations:

For the purpose of Section 3(f) of the Agreement, Counterparty makes the following representation to Dealer:
