The Investor understands that the exchange (the “Exchange”) is being made without registration of the offer or sale of the Shares under the Securities Act of 1933, as amended (the “Securities Act”), or any securities laws of any state of the United States or of any other jurisdiction in a private placement pursuant to the exemption from registration provided by Section 4(a)(2) of the Securities Act and that each Exchanging Investor participating in the Exchange is required to be an institutional “accredited investor” within the meaning of Rule 501(a)(1), (2), (3) or (7) of Regulation D under the Securities Act that is also a “qualified institutional buyer” within the meaning of Rule 144A under the Securities Act. Capitalized terms used but not defined in this Agreement have the respective meanings set forth in the indenture, dated as of September 16, 2019, (the “Indenture”) between the Company and U.S. Bank National Association, as trustee (the “Trustee”).

1. Exchange. On the basis of the representations, warranties and agreements herein contained and subject to the terms and conditions herein set forth, the Investor hereby agrees to exchange for itself and on behalf of the Exchanging Investors, an aggregate principal amount of the Notes set forth on Exhibit A hereto (the “Exchanged Notes”) for:

(a) a number of Shares per $1,000 principal amount of such Exchanged Notes equal to 20.2724; plus

(b) an additional number of Shares per $1,000 principal amount of such Exchanged Notes equal to the quotient of (i) $591.91 divided by (ii) the average of the Daily VWAPs (as defined below) over the Reference Period (as defined below) (the aggregate number of Shares under clause (a) and (b), the “Exchange Consideration”);

in each case, as adjusted in good faith by the Company for any stock dividend, stock split, stock combination, reclassification or similar transaction occurring on or after the date hereof and prior to the Closing Date; provided that the number of Shares to be exchanged for the Exchanged Notes shall be rounded down to the nearest whole share for each Exchanging Investor.

For the avoidance of doubt, no cash will be paid to any Exchanging Investor in respect of any accrued and unpaid interest on the Exchanged Notes.

Notwithstanding the foregoing, in no event shall the number of shares of Common Stock issuable under this Agreement and in exchange for other Notes pursuant to any other exchange agreement entered into on or about the date of this Agreement (the “Other Exchange Agreements”) between the Company and holders of such other Notes with respect to the exchange of Notes for Common Stock exceed 19.9% of the Company’s issued and outstanding Common Stock on the

date hereof (the “Threshold”). If such aggregate amount of shares of Common Stock were to exceed the Threshold, (i) the aggregate number of such shares of Common Stock to be issued under this Agreement and the Other Exchange Agreements shall be allocated among the Exchanging Investors and the “Exchanging Investors” under the Other Exchange Agreements on a pro rata basis based on the principal amount of Notes intended to be exchanged by each such Exchanging Investor under this Agreement and the Other Exchange Agreements and (ii) the percentage reduction in the number of shares of Common Stock to be issued under this Agreement pursuant to clause (i) shall be multiplied by the face amount of the Exchanged Notes and such amount of Exchanged Notes shall not be considered Exchanged Notes, shall not be exchanged hereunder and shall be returned to the Investor.

“Business Day” means 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.

“Daily VWAP” means, for each Trading Day (as defined below) in the Reference Period (as defined below), the per share volume-weighted average price of the Common Stock as displayed under the heading “Bloomberg VWAP” on Bloomberg page “APLS <equity> AQR” (or its equivalent successor if such page is not available) in respect of the period from the scheduled open of trading until the scheduled close of trading of the primary trading session on such Trading Day (or if such volume-weighted average price is unavailable, the Last Reported Sale Price on such day). The “Daily VWAP” shall be determined without regard to after-hours trading or any other trading outside of the regular trading session trading hours.

“Last Reported Sale Price” of the Common Stock on any date means the closing sale price per share (or if no closing sale price is reported, the average of the bid and ask prices or, if more than one in either case, the average of the average bid and the average ask prices) on that date as reported in composite transactions for the principal U.S. national or regional securities exchange on which the Common Stock is traded.

“Market Disruption Event” means (a) a failure by the primary U.S. national or regional securities exchange or market on which the Common Stock is listed or admitted for trading to open for trading during its regular trading session or (b) the occurrence or existence prior to 1:00 p.m., New York City time, on any Scheduled Trading Day (as defined in the Indenture) for the Common Stock 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 Common Stock or in any options contracts or futures contracts relating to the Common Stock.

“Reference Period” means the period of three (3) consecutive Trading Days commencing on the first Trading Day following the date hereof.

“Trading Day” means a day on which (a) there is no Market Disruption Event and (b) trading in the Common Stock generally occurs on The Nasdaq Global Select Market or, if the Common Stock is not then listed on The Nasdaq Global Select Market, on the principal other U.S. national or regional securities exchange on which the Common Stock is then listed or, if the Common Stock is not then listed on a U.S. national or regional securities exchange, on the principal other market on which the Common Stock is then listed or admitted for trading, except that if the Common Stock is not so listed or admitted for trading, “Trading Day” means a Business Day.

The Investor agrees that it and any Exchanging Investor shall not deliver a Notice of Conversion with respect to any Exchanged Notes and the Investor and each Exchanging Investor shall hold the Exchanged Notes until the Closing (as defined below). In consideration for the performance of their obligations hereunder (including as described in the immediately preceding sentence), the Company agrees to deliver the Exchange Consideration on the Closing Date (as defined below) to each Exchanging Investor in exchange for its Exchanged Notes.

The Exchange shall occur in accordance with the procedures set forth in Exhibit B.2 hereto (the “Exchange Procedures”); provided that each of the Company and the Investor acknowledges that the delivery of the Shares to any Exchanging Investor may be delayed due to procedures and mechanics within the system of American Stock Transfer & Trust Company, LLC, The Depositary Trust Company (“DTC”) or The Nasdaq Global Select Market (“Nasdaq”) (including the procedures and mechanics regarding the listing of the Shares on Nasdaq) or other events beyond the Company’s control and that such a delay will not be a default under this Agreement so long as (i) the Company is using its reasonable best efforts to effect such delivery, or (ii) such delay arises due to a failure by Investor to deliver settlement instructions in accordance with Section 3(s); provided, further, that no delivery of Shares will be made until the Exchanged Notes have been properly submitted for exchange in accordance with the Exchange Procedures and no accrued interest will be payable by reason of any delay in making such delivery.

The closing of the Exchange (the “Closing”) shall take place remotely via the exchange of documents and signatures at 10:00 a.m., New York City time, on August 4, 2022 (the “Closing Date”), or at such other time and place as the Company and the Investor may mutually agree.

All questions as to the form of all documents and the validity and acceptance of the Exchanged Notes and the Exchange Consideration will be determined by the Company, in its sole discretion, which determination shall be final and binding. Subject to the terms and conditions of this Agreement, the Investor hereby, for itself and on behalf of its Accounts, (a) waives any and all other rights with respect to such Exchanged Notes and (b) releases and discharges the Company from any and all claims the undersigned and its Accounts may now have, or may have in the future, arising out of, or related to, such Exchanged Notes.

The Investor and each Exchanging Investor understands, based on its experience, the disadvantage to which the Investor and each Exchanging Investor is subject due to the disparity of information between the Company, on the one hand, and the Investor and each Exchanging Investor, on the other hand. Notwithstanding this, the Investor and each Exchanging Investor has deemed it appropriate to participate in the Exchange. The Investor agrees that the Company and its directors, officers, employees, agents, stockholders and affiliates shall have no liability to the Investor or any Exchanging Investor or their respective beneficiaries whatsoever due to or in connection with the Company’s use or non-disclosure of the Information or otherwise as a result of the Exchange, and the Investor hereby irrevocably waives any claim that it or any Exchanging Investor might have based on the failure of the Company to disclose the Information.

16. Severability. If any term or provision of this Agreement (in whole or in part) is invalid, illegal or unenforceable in any jurisdiction, such invalidity, illegality or unenforceability shall not affect any other term or provision of this Agreement or invalidate or render unenforceable such term or provision in any other jurisdiction.

18. Termination. This Agreement may be terminated and the transactions contemplated hereby abandoned (a) by mutual agreement of the Company and the Investor in writing or (b) by either the Company or the Investor if the conditions to such party’s obligations set forth herein have not been satisfied (unless waived by the party entitled to the benefit thereof), and the Closing has not occurred on or before August 9, 2022 without liability of either the Company or the Investor or the Exchanging Investors, as the case may be; provided that neither the Company nor the Investor shall be released from liability hereunder if this Agreement is terminated and the transactions abandoned by reason of the failure of the Company or the Investor or any of the Exchanging Investors, as the case may be to have performed its obligations hereunder.

The Investor further acknowledges that, if an Exchanging Investor is not a United States person for U.S. federal income tax purposes, the Company must be provided with a properly completed and executed IRS Form W-8BEN, IRS Form W-8BEN-E, IRS Form W-8IMY (and all required attachments) or other applicable IRS Form W-8, attesting to that non-U.S. Exchanging Investor’s foreign status and certain other information, including information establishing an exemption from withholding under Sections 1471 through 1474 of the Internal Revenue Code of 1986, as amended (the “Code”). The Investor further acknowledges that any Exchanging Investor may be subject to 30% U.S. federal withholding or 24% U.S. federal backup withholding on certain payments made to such Exchanging Investor unless such Exchanging Investor properly establishes an exemption from, or a reduced rate of, such withholding or backup withholding. See Exhibit C for certain additional information. The Company and its agents shall be entitled to deduct and withhold from any consideration payable pursuant to this Agreement such amounts as are required to be deducted or withheld under applicable law. To the extent any such amounts are withheld and remitted to the appropriate taxing authority, such amounts shall be treated for all purposes as having been paid to the Exchanging Investor to whom such amounts otherwise would have been paid.

B.2-1

EXHIBIT C

Under U.S. federal income tax law, a holder who exchanges Notes for Shares generally must provide such holder’s correct TIN on a properly completed and executed IRS Form W-9 (available from the Company or at xxx.xxx.xxx/xxx/xxx-xxx/xx0.xxx) or otherwise establish a basis for exemption from backup withholding. A TIN is generally an individual holder’s social security number or a holder’s employer identification number. If the correct TIN is not provided, the holder may be subject to a $50 penalty imposed under Section 6723 of the Code. In addition, certain payments made to holders may be subject to U.S. backup withholding (currently set at 24% of the payment). If a holder is required to provide a TIN but does not have a TIN, the holder should consult its tax advisor regarding how to obtain a TIN. Certain holders (including corporations and non-U.S. holders) are not subject to these backup withholding and reporting requirements.

A non-U.S. holder (i) will be subject to 30% U.S. federal withholding unless such holder establishes an exemption from, or a reduced rate of, such withholding, and (ii) must establish its status as an exempt recipient from backup withholding and can do so by submitting a properly completed IRS Form W-8BEN, IRS Form W-8BEN-E, IRS Form W-8IMY (and all required attachments), or other applicable IRS Form W-8 (available from the Company or at xxx.xxx.xxx), signed, under penalties of perjury, attesting to such holder’s exempt foreign status. This form also may establish an exemption from withholding under Section 1471 through 1474 of the Code.

U.S. backup withholding is not an additional tax. Rather, the U.S. federal income tax liability of persons subject to backup withholding will be reduced by the amount of tax withheld. If withholding results in an overpayment of taxes, a refund may be obtained provided that the required information is timely furnished to the IRS. Holders are urged to consult their tax advisors regarding how to complete the appropriate forms and to determine whether they are exempt from backup withholding or other withholding taxes.
