designated transfer agent (the “Transfer Agent”), which confirmation shall constitute an instruction to the Transfer Agent to process such Conversion Notice in accordance with
the terms herein and (II) on or before the second (2nd) Trading Day (or, if earlier, the last day of the Standard Settlement Period) following the date of receipt or deemed receipt by the Company of such Conversion Notice or, in the case of

aggregate number of Conversion Shares to which the Holder shall be entitled to the Holder’s or its designee’s balance account with The Depository Trust Company (“DTC”) through its Deposit/Withdrawal at Custodian system, or
(B) if the foregoing shall not apply, issue and deliver to the address as specified in the Conversion Notice, a share or stock certificate (as the case may be), registered in the name of the Holder or its designee, for the number of Conversion
Shares to which the Holder shall be entitled. If this Note is submitted for conversion, and the Principal represented by this Note is greater than the Principal being converted, then the Company shall, as soon as practicable and in no event later
than three (3) Trading Days after receipt of this Note (the “Note Delivery Date”) and at its own expense, issue and deliver to the Holder a new Note representing the Principal not converted and cancel this Note. This Note and
the Conversion Shares will be free-trading, and freely transferable, and will not contain a legend restricting the resale or transferability of the Conversion Shares if any of the Unrestricted Conditions (as defined below) is met.

accounting firm, as the case may be. The Company shall direct the investment bank or the accounting firm, as the case may be, to perform the determinations or calculations and notify the Company and the Holder of the results no later than two
(2) Business Days from the time it receives the disputed determinations or calculations. Such investment bank’s or accounting firm’s determination or calculation, as the case may be, shall be binding upon all parties absent manifest
error. Notwithstanding anything herein to the contrary, any such final determination in respect of a dispute in connection with a Major Transaction in which the Company is not the surviving parent entity, shall be made prior to consummation of such
Major Transaction. 
 (iv) Record Holder. The person or persons entitled to receive the Conversion Shares issuable upon a conversion
of this Note shall be treated for all purposes as the legal and record holder or holders of such Shares upon delivery of the Conversion Notice via facsimile, electronic mail or otherwise

Amount, then in addition to all other available remedies that the Holder may pursue hereunder and under the Facility Agreement, the Company shall pay additional damages to the Holder for each 30-day period
(prorated for any partial period) after the Cash Damages Trigger Date such conversion is not timely effected in an amount equal to one and one-half percent (1.5%) of (y) in the case of a failure to timely

make such payments, to require the Company, upon written notice, to immediately issue, in lieu of such cash damages, the number of Shares equal to the quotient of (X) the aggregate amount of the damages payments described herein divided by
(Y) the Conversion Price in effect on such Conversion Date as specified by the Holder in the Conversion Notice.

all of the Principal is being converted or redeemed. The Holder and the Company shall maintain records showing the Principal converted or redeemed and the dates of such conversions or redemptions or shall use such other method, reasonably
satisfactory to the Holder and the Company, so as not to require physical surrender of this Note upon any such partial conversion or redemption. Notwithstanding the foregoing, if this Note is converted or redeemed as aforesaid, the Holder may not
transfer this Note unless the Holder first physically surrenders this Note to the Company, whereupon the Company will forthwith issue and deliver upon the order of the Holder a new Note of like tenor, registered as the Holder may request,
representing in the aggregate the remaining Principal represented by this Note. The Holder and any assignee, by acceptance of this Note, acknowledge and agree that, by reason of the provisions of this paragraph, following conversion or redemption of
any portion of this Note, the Principal of this Note may be less than the principal amount stated on the face hereof. 
 (d) Taxes.
The Company shall pay any and all Other Taxes that may be payable with respect to the issuance and delivery of Conversion Shares upon the conversion of this Note. For greater certainty, the provisions of Section 2.4 of the Facility Agreement
shall apply with respect to any and all Taxes with respect to payments by the Company (or any other applicable Credit Party) hereunder, including with respect to the delivery of Conversion Shares upon the conversion of this Note. 

(e) Legends. 
 (i)
Restrictive Legend. The Holder understands that until such time as this Note or the Conversion Shares have been registered under the Securities Act and applicable state securities laws as contemplated by the Registration Rights Agreement or
otherwise may be sold pursuant to Rule 144 under the Securities Act or another exemption from registration under the Securities Act without any restriction as to the number of securities as of a particular date that can then be immediately sold,
this Note and the Conversion Shares, as applicable, may bear a restrictive legend in substantially the following form (and a stop-transfer order consistent therewith may be placed against transfer of the certificates for such securities): 

  
 11 













 Execution Version 

 

 “THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE
SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE STATE SECURITIES LAWS. THE SECURITIES MAY NOT BE SOLD, TRANSFERRED, ASSIGNED, PLEDGED, HYPOTHECATED OR OTHERWISE DISPOSED OF IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES
UNDER SAID ACT, OR PURSUANT TO AN EXEMPTION FROM REGISTRATION UNDER SAID ACT INCLUDING, WITHOUT LIMITATION, PURSUANT TO RULES 144 OR 144A UNDER SAID ACT OR PURSUANT TO A PRIVATE SALE EFFECTED UNDER SECTION 4(A)(7) OF THE SECURITIES ACT OR APPLICABLE
FORMAL OR INFORMAL SEC INTERPRETATION OR GUIDANCE, SUCH AS A SO-CALLED “4(a)(1) AND A HALF” SALE.” 

“THE SALE, TRANSFER OR ASSIGNMENT OF THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO THE TERMS AND CONDITIONS OF A CERTAIN
AMENDED AND RESTATED REGISTRATION RIGHTS AGREEMENT DATED AS OF OCTOBER 12, 2022, AS AMENDED FROM TIME TO TIME, AMONG THE COMPANY AND CERTAIN HOLDERS OF ITS OUTSTANDING SECURITIES. COPIES OF SUCH AGREEMENT MAY BE OBTAINED AT NO COST BY WRITTEN
REQUEST MADE BY THE HOLDER OF RECORD OF THIS CERTIFICATE TO THE SECRETARY OF THE COMPANY.” 
 The Conversion Shares may be issued
without registration thereof under the Securities Act in reliance on a valid exemption under the Securities Act. 
 (ii) Removal of
Restrictive Legends. This Note and the certificates evidencing the Conversion Shares (including any Major Transaction Company Shares), as applicable, shall not contain any securities legend restricting the transfer thereof (including the legends
set forth above in subsection 2(e)(i)): (A) while a registration statement (including a Registration Statement, as defined in the Registration Rights Agreement) covering the sale or resale of the Conversion Shares is effective under the Securities
Act, or (B) following any sale of such Note and/or Conversion Shares pursuant to such a registration statement or Rule 144, or (C) if such Note or Conversion Shares, as the case may be, are eligible for sale under Rule 144(b)(1), or
(D) if at any time on or after the date hereof (y) the Holder certifies that it is not an “affiliate” within the meaning of such term under Rule 144 and that the Holder’s holding period for purposes of Rule 144 and, in the
case of the Conversion Shares, subsection (d)(3)(ii) thereof with respect to such Note and/or Conversion Shares is at least six (6) months, and (z) if such holding period is less than twelve (12) months, the Company has filed all
reports on Form 10-K and Form 10-Q required to be filed by the Company during the preceding twelve (12) months, or (E) if such legend is not required under
applicable requirements of the Securities Act (including judicial interpretations and pronouncements issued by the staff of the SEC) (collectively, the “Unrestricted Conditions”). The Company shall cause its counsel to issue a legal
opinion to the Transfer Agent promptly after the Effective Date (as defined below), or at such other time as any of the Unrestricted Conditions have been satisfied, if required by the Company’s transfer agent to effect the issuance of this Note
or the Conversion Shares, as applicable, without a restrictive legend or removal of the legend hereunder. If any of the Unrestricted Conditions is met at the time of issuance of any of the Conversion Shares, then such Conversion Shares shall be
issued free of all United States legends. The Company agrees that 

  
 12 













 Execution Version 

 

 
following the Effective Date or at such time as any of the Unrestricted Conditions is met or such United States legend is otherwise no longer required under this
Section 2(e), it will, no later than two (2) Trading Days Day (or, if fewer, the number of days comprising the Standard Settlement Period) following the delivery (the “Unlegended Shares Delivery
Deadline”) by the Holder to the Company or the Transfer Agent of this Note and a certificate representing Conversion Shares, as applicable, issued with a restrictive United States legend (such third Trading Day, the “Legend Removal
Date”), deliver or cause to be delivered to such Holder this Note and/or a certificate (or electronic transfer) representing such Shares that is free from all restrictive and other United States legends. For purposes hereof, “Effective
Date” shall mean the date that the Registration Statement that the Company is required to file pursuant to the Registration Rights Agreement and covering the Conversion Shares has been declared effective by the SEC. 

(iii) Sale of Unlegended Shares. Holder agrees that the removal of the restrictive securities legend from this Note and any certificates
representing securities as set forth in Section 2(e)(i) above is predicated upon the Company’s reliance that the Holder will sell this Note or any Conversion Shares, as applicable, pursuant to either the registration
requirements of the Securities Act and applicable state securities laws, including any applicable prospectus delivery requirements, or an exemption therefrom, and that if such securities are sold pursuant to a Registration Statement, they will be
sold in compliance with the plan of distribution set forth therein. 
 (f) Dividend, Subdivision, Combination or Reclassification. If
the Company shall, at any time or from time to time, (A) declare a dividend on the Common Stock, or capitalization of profits or reserves, payable in shares of its Capital Stock (including Common Stock), other than a dividend for which the
Holder would be entitled to participate pursuant to Section 6, (B) subdivide the outstanding shares of Common Stock into a larger number of shares of Common Stock, (C) consolidate or combine the outstanding shares of Common Stock into a
smaller number of shares of its Common Stock or (D) issue any shares of its Capital Stock in a reclassification of the Common Stock (including any such reclassification in connection with a consolidation or merger in which the Company is the
continuing corporation), or (E) repay or reduce its capital or otherwise adjust the nominal value of its Shares, then in each such case, the Conversion Price in effect at the time of the record date for such dividend or of the effective date of
such subdivision, combination or reclassification shall be adjusted so that the Holder of this Note upon conversion after such date shall be entitled to receive the aggregate number and kind of shares of its Capital Stock which, if this Note had
been converted immediately prior to such date, such holder would have owned upon such conversion and been entitled to receive by virtue of such dividend, subdivision, combination or reclassification. Any such adjustment shall become effective
immediately after the record date of such dividend or the effective date of such subdivision, combination or reclassification. Such adjustment shall be made successively whenever any event listed above shall occur. If a dividend on the Common Stock,
or capitalization of profits or reserves, payable in shares of its Capital Stock (including Common Stock) is declared and such dividend is not paid, the Conversion Price shall again be adjusted to be the Conversion Price, in effect immediately prior
to such record date (giving effect to all adjustments that otherwise would be required to be made pursuant to this Section 2 from and after such record date).

 Execution Version 

 

 (g) Authorized Share Cap. Notwithstanding anything to the contrary
contained herein, during the Authorized Share Conversion Restriction Period, the Company shall not issue, upon conversion of this Note (in whole or in part) Shares in an amount greater than the difference of (i) the Authorized Share Cap Amount,
as then in effect, minus (ii) the aggregate number of Conversion Shares and Warrant Shares (as defined in the Warrants) (in each case, subject to appropriate adjustment for any Stock Event that occurs after the issuance of any Conversion Shares
or Warrant Shares, as applicable) issued prior to such time upon conversion of Notes and exercise of Warrants by the Holder (subject to adjustment as provided herein, the “Cap Allocation Amount”). In the event that the Holder
shall sell or otherwise transfer this Note (in whole or in part), the Cap Allocation Amount applicable hereto immediately prior to such transfer shall be allocated to the Note acquired by the transferee as shall be determined by the Holder and such
transferee. 
 (h) Cash Settlement. Upon the conversion of this Note (in whole or in part) by the Holder during the Cash Settlement
Period, the Company shall not issue any Excess Conversion Shares, and, in lieu of delivering Excess Conversion Shares, shall pay to the Holder an amount in cash (the “Cash Settlement Amount”) equal to the product of (A) the
number of Excess Conversion Shares (including, for the avoidance of doubt, in the case of any Major Transaction Conversion in respect of a Company Share Major Transaction, the Base Conversion Shares and the Additional Conversion Shares),
multiplied by (B) the Closing Price on the Trading Day immediately preceding the Conversion Date. For the avoidance of doubt, the Holder shall not be required to specify (in a Conversion Notice or otherwise) whether a conversion would
result in Excess Conversion Shares or require payment of a Cash Settlement Amount. Notwithstanding anything to the contrary contained herein, if the Holder delivers a Conversion Notice at any time during the Authorized Share Conversion Restriction
Period, any Principal elected to be converted pursuant to such Conversion Notice (but solely to the extent in respect of any applicable Excess Conversion Shares) shall be deemed to be outstanding, and shall continue to bear interest, until the date
the Cash Settlement Amount in respect of such Principal shall have been paid to the Holder (except, for the avoidance of doubt, that if the Holder delivers a Void Conversion Notice with respect thereto, such Principal shall thereafter remain
outstanding and bear interest until it is otherwise satisfied or converted in accordance with the terms hereof and of the Facility Agreement). The Cash Settlement Amount shall be paid, in cash, to the Holder within three (3) Business Days
following the Conversion Date in accordance with instructions provided by Holder for payments under the Facility Agreement. In the event that (i) the Company consummates a Major Transaction, the Company shall pay, or cause the relevant
Successor Entity to pay, to each Holder, concurrently with the consummation of such Major Transaction, all Cash Settlement Amounts payable to the Holder that remain unpaid as of the date such Major Transaction is consummated or (ii) the
Obligations become due and payable pursuant to the Facility Agreement, all Cash Settlement Amounts that remain unpaid and are not yet due and payable shall simultaneously become due and payable to the each Holder to which such Cash Settlement
Amounts are then payable. 
 3. Rights Upon Major Transaction. In the event that a Major Transaction occurs, then the Holder, at its
option, may (i) require the Company to repay in cash all or a portion of the principal amount outstanding on the Holder’s Notes plus all accrued and unpaid Interest thereon and any other amounts payable under the Facility Agreement
(including the Make Whole Amount), in accordance with Section 5.19 of the Facility Agreement or (ii) convert all or a portion of the principal amount outstanding in accordance with the provisions of this
Section 3 (a “Major  

  
 14 













 Execution Version 

 

 
Transaction Conversion”) and cause the Company to pay to the Holder all accrued and unpaid Interest under this Note. The Holder shall have the right to waive its rights under this
Section 3 with respect to such Major Transaction. 
 (a) Major Transaction Conversion. In the event that a
Major Transaction occurs, then (1) in the case of a transaction covered by the provisions of clause (A) of the definition of “Major Transaction” in which the Common Stock of the Company is converted into the right to receive
cash, securities of another entity and/or other assets (a “Successor Major Transaction”), the Holder, at its option, may convert, in whole or in part, the outstanding principal amount under this Note into the right to receive upon
consummation of the Major Transaction, the amount of cash and other assets and the number of securities or other property of the Successor Entity or other entity that the Holder would have received had such Holder converted the Major Transaction
Conversion Amount (as defined below) into Base Conversion Shares and Additional Conversion Shares (as defined below and without regard to the Beneficial Ownership Cap, the Cap Allocation Amount, the existence of the Authorized Share Conversion
Restriction Period and any other limitations on conversion herein or elsewhere and without regard to whether or not a sufficient number of shares are authorized, reserved and available to effect any such conversion and issuance) immediately prior to
the consummation of such Major Transaction (the “Successor Consideration”) and (2) in the case of any other Major Transactions not covered under clause (1) above (a “Company Share Major Transaction”), the
Holder shall have the right to convert, in whole or in part, and from time to time, the outstanding principal amount under this Note into Base Conversion Shares and Additional Conversion Shares (or to the extent such Base Conversion Shares and/or
Additional Conversion Shares constitute Excess Conversion Shares, the Cash Settlement Amount with respect thereto), without regard to the Cap Allocation Amount (“Major Transaction Company Shares”). 

(b) Base Conversion Shares and Additional Conversion Shares. Notwithstanding anything herein to the contrary, with respect to any
conversion or deemed conversion effected in connection with a Major Transaction pursuant to this Section 3, the aggregate total number of Major Transaction Company Shares (or applicable Cash Settlement Amounts) into which
all or any portion of the principal amount of this Note may be converted or, the aggregate number of conversion shares to be used for calculating the Successor Consideration, as applicable, shall be calculated to be the sum of (a) the number of
shares of Common Stock into which the principal amount of this Note then being converted would otherwise be converted as calculated under Section 2 hereof (such number of shares, the “Base Conversion Shares”), plus (b) the
number of shares of Common Stock equal to the product of (x) the Additional Share Coefficient (as such term is defined and determined for each $1,000 of principal amount of this Note on Schedule I attached hereto and made a part hereof) for
such Major Transaction and (y) a fraction the numerator of which is the amount of the principal amount of this Note then being converted and the denominator of which is $1,000 (such number of shares of Common Stock calculated in accordance with
this clause (b), the “Additional Conversion Shares”). 
 (c) Notice; Major Transaction Conversion Election. At least
thirty (30) days prior to the consummation of any Major Transaction but, in any event, within one (1) Business Day following the first to occur of (x) the date of the public announcement of such Major Transaction if such announcement
is made before 4:00 p.m., New York City time, or (y) the day following the public 

  
 15 













 Execution Version 

 

 
announcement of such Major Transaction if such announcement is made on and after 4:00 p.m., New York City time, the Company shall deliver written notice thereof via (i) facsimile or
electronic mail and (ii) overnight courier to the Holder (a “Major Transaction Notice”); provided, however, that, with respect to any Major Transaction that is not a Successor Major Transaction, the applicable deadline by which
the Company must deliver the Major Transaction Notice shall be within one (1) Business Day following (x) the date of the first public announcement by any Person of such Major Transaction if such announcement is made before 4:00 p.m., New
York City time, or (y) the day following the first public announcement by any Person of such Major Transaction if such announcement is made on or after 4:00 p.m., New York City time; and provided, further, that the Company shall make a public
announcement of any Major Transaction not later than two (2) Trading Days after the Company first has knowledge of the occurrence thereof. Any Major Transaction Change Notice or other notice delivered or
re-sent (or required to be delivered or re-sent) by or on behalf of the Company pursuant to this Section 3 shall be delivered (or
re-sent, as applicable) to the Holder and its counsel by email or overnight courier. Each Major Transaction Notice shall prominently indicate that it is a “Major Transaction Notice” and the subject
of any email that contains or attaches a Major Transaction Notice shall be “Sientra – Major Transaction Notice.” Each Major Transaction Notice shall set forth the date on which the applicable Major Transaction has been or will be
consummated (or, if such date is not known, the Company’s good faith estimate of the date of such consummation). If a Major Transaction shall not have been consummated within thirty (30) days following the date the Major Transaction Notice
with respect thereto shall have first been delivered to the Holder, then promptly following such thirtieth (30th) day, such Major Transaction Notice shall be re-sent in accordance with this Section 3(c)
(excepting the time period requirement for delivery set forth above and provided, that such notice shall be updated, if applicable, to reflect the Company’s good faith estimate of the date on which the Major Transaction will be consummated as
of the date such notice is re-sent). Without limiting the rights and remedies of the Holder hereunder or under the Facility Documents or otherwise at law or in equity, the failure to timely deliver or re-send any Major Transaction Notice or other notice pursuant to this Section 3 or to include any required information in such notice shall toll any time period hereunder for any response responding to, or
taking any action following, such notice by the Holder. At any time during the Major Transaction Conversion Period, the Holder may elect to effect a Major Transaction Conversion by delivering written notice thereof (“Major Transaction
Conversion Notice”) to the Company, which Major Transaction Conversion Notice shall indicate the portion of the Note (the “Major Transaction Conversion Amount”), calculated with reference to the principal amount outstanding
that the Holder is electing to treat as a Major Transaction Conversion. For the avoidance of doubt, the Holder shall be permitted to make successive conversions and send successive Major Transaction Conversion Notices in respect of a Company Share
Major Transaction from time to time at any time during the Major Transaction Conversion Period. 
 (d) Settlement of Major Transaction
Conversion. Following the receipt of a Major Transaction Conversion Notice from the Holder, the Company shall not effect a Successor Major Transaction that is being treated as a Major Transaction Conversion unless at the time of the execution of
the definitive documentation relating to such Major Transaction it obtains the written agreement of the Successor Entity that payment or issuance of the Successor Consideration plus accrued and unpaid interest through the date of payment, shall be
made to the Holder prior to consummation of such Major Transaction and such payment or issuance, as the case may be, shall be a 

  
 16 













 Execution Version 

 

 
condition precedent to consummation of such Major Transaction. Concurrently upon closing of such Successor Major Transaction, the Company shall pay or issue, as the case may be, or shall instruct
any escrow agent for the transaction to pay or issue, and will cause the Successor Entity to issue and/or pay, the applicable Successor Consideration, plus accrued and unpaid interest through the date of payment. Any Major Transaction Company Shares
issuable in respect of a Company Share Major Transaction shall be issued to the Holder within three (3) Trading Days following the date of each Major Transaction Conversion Notice. 

(e) Damages. Following the receipt of a Major Transaction Conversion Notice from the Holder, in the event that the Company attempts to
consummate a Successor Major Transaction without obtaining the written agreement of the Successor Entity described in subsection (d) above, the Holder shall have the right to apply for an injunction in any state or federal courts sitting within
Wilmington, Delaware to prevent the closing of such Major Transaction until the Successor Consideration is satisfied to the Holder in full. 

Notwithstanding anything to the contrary contained herein and without derogating any obligations or rights herein, until the Holder receives
its appropriate payment or securities, plus any accrued and unpaid interest under this Note, in accordance with the provisions of this Section 3, this Note may be converted, in whole or in part, by the Holder into Shares,
or in the event that such payments and/or shares have not been delivered prior to the consummation of the Successor Major Transaction in which the Company is not the surviving parent entity, Common Stock (or its equivalent) of the Successor Entity
at an appropriate conversion price based upon the prevailing Conversion Rate (as adjusted hereunder) at the time of such Major Transaction and price per share or conversion ratio received by holders of Common Stock in the Major Transaction. 

4. Registration Failures. Upon any Registration Failure, in addition to all other available remedies that the Holder may pursue
hereunder and under the Facility Agreement, the Registration Rights Agreement and this Note, the Company shall pay additional damages to the Holder for each 30-day period (prorated for any partial period)
after the date of such Registration Failure in an amount in cash equal to one and one-half percent (1.5%) of such Holder’s original principal amount of this Note on the date of such Registration Failure.
Such payments shall accrue until the earlier of (i) such time as the Registration Failure has been cured and (ii) the date on which all of the Conversion Shares may be sold without restriction under Rule 144 (including, without limitation,
volume restrictions and without the need for the availability of current public information under Rule 144). All such payments that accrue under this Section 4 shall be payable no later than five (5) business days following such date of
accrual. 
 5. Voting Rights. Except as required by law, the Holder shall have no voting rights with respect to any of the Conversion
Shares until delivery of the Conversion Notice relating to the conversion of this Note upon which such Conversion Shares are issuable. 
 6.
Participation. The Holder, as the holder of this Note, shall be entitled to receive such dividends paid and distributions of any kind made to the holders of Common Stock to the same extent as if the Holder had converted this Note into shares
of Common Stock (without regard to any limitations on exercise herein or elsewhere and without regard to whether or not a sufficient number of shares are authorized and reserved to effect any such exercise and issuance) and had held such shares of
Common Stock on the record date for such dividends and distributions. Payments under the 

  
 17 













 Execution Version 

 

 
preceding sentence shall be made concurrently with the dividend or distribution to the holders of Common Stock. To the extent the payment of any dividend or making of any distribution pursuant to
this Section 6 would result in a Holder receiving Shares or other voting equity securities in excess of the Beneficial Ownership Cap or Cap Allocation Amount, such Holder shall not receive such excess Shares and, in lieu thereof, the Company
shall pay to such Holder in cash an amount equal to the product of (i) the number of such excess Shares multiplied by (ii) the difference produced by subtracting the Conversion Price from the Closing Market Price immediately prior to the
making of such dividend or distribution. For the avoidance of doubt, if at any time the Company grants, issues or sells any options, convertible securities or rights to purchase stock, warrants, securities or other property pro rata to the record
holders of any class of its capital stock (the “Purchase Rights”), then the Holder will be entitled to acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights that the Holder could have acquired if
it had held the number of Shares acquirable upon conversion in full of this Note (without regard to any limitations on conversion herein or elsewhere and without regard to whether or not a sufficient number of shares are authorized and reserved to
effect any such conversion and issuance) held by the Holder immediately before the date on which a record is taken for the grant, issuance or sale of such Purchase Rights, or, if no such record is taken, the date as of which the record holders of
Common Stock are to be determined for the grant, issue or sale of such Purchase Rights. 
 7. Optional Redemption. 

(a) Subject to the terms, conditions and limitations set forth in this Section 7, the Company shall have the right to redeem (an
“Optional Redemption”) the Principal amount of this Note for the Optional Redemption Price. The Company shall not effect any Optional Redemption under this Note unless, contemporaneously with such Optional Redemption, the Company
effects an Optional Redemption under all of the other Original Loan Convertible Notes in accordance with the terms thereof, on a pro rata basis, based upon the respective applicable original principal amount of each of the Notes outstanding as of
the date the Optional Redemption Notice is delivered to the holders of the Notes. 
 (b) To effect an Optional Redemption, the Company shall
send a written notice via electronic mail to the Holder (an “Optional Redemption Notice”) at any time between 4:00 p.m. and 5:00 p.m., New York City time, on a Trading Day and shall also deliver the Optional Redemption Notice to the
Holder by overnight courier for delivery on the next Business Day. Each Optional Redemption Notice shall certify that the applicable conditions set forth in this Section 7 have been satisfied and shall indicate: (i) that the Company has
elected to effect an Optional Redemption, (ii) the Principal amount hereunder that the Company is electing to redeem (the “Principal Redemption Amount”), (iii) the Optional Redemption Date, (iv) the aggregate principal
amount of all Notes outstanding as of the date of the Optional Redemption Notice, (v) the aggregate principal amount of the Notes to be redeemed on the Optional Redemption Date, (vi) the number of shares underlying the Warrant(s) issuable
to the Holder in respect of the Principal Redemption Amount (the “Warrant Share Number”) and the other terms of such Warrants in accordance with Section 2.9 of the Facility Agreement, and (vii) if the applicable Optional
Redemption is conditional upon the consummation of a transaction as permitted by Section 7(c), a statement to such effect and a summary description of the transaction on which the applicable Optional Redemption is conditioned. Simultaneously
with the delivery of an Optional Redemption Notice 

  
 18 













 Execution Version 

 

 
to the Holder hereunder, the Company shall send an Optional Redemption Notice to the holders of each of the other Original Loan Convertible Notes in respect of the applicable principal amount of
such Notes. 
 (c) If the Company elects to exercise its Optional Redemption right, it shall fix (and specify in the applicable Optional
Redemption Notice) a date for redemption (an “Optional Redemption Date”), which shall be at least two (2) Trading Days prior to the Maturity Date and at least thirty (30) days but no more than sixty (60) days
following the date the applicable Optional Redemption Notice is delivered to the holders of Notes. The Optional Redemption Notice (and each Optional Redemption Notice delivered to holders of the other Original Loan Convertible Notes) shall be
irrevocable (subject to the termination right of the Holder pursuant to Section 7(d)) and, upon delivery of an Optional Redemption Notice, the Optional Redemption Price, less the sum of all Redemption Period Conversion Amounts (as defined
below), together with accrued and unpaid interest thereon through the date of payment thereof (and any other amounts payable thereon under the Facility Agreement, including the Make Whole Amount) shall become due and payable, and a Warrant in
respect of the Warrant Share Number applicable to the Principal Redemption Amount shall become issuable in accordance with Section 2.9 of the Facility Agreement, on the Optional Redemption Date; provided that an Optional Redemption may be
conditional upon the consummation of a specified transaction, if so indicated in the applicable Optional Redemption Notice, on the proposed Optional Redemption Date. In the event that the Optional Redemption is conditional upon consummation of a
transaction, the Company shall notify the Holder, and publicly disclose, by no later than 8:00 a.m. (New York City time) on the Optional Redemption Date whether the applicable transaction has been consummated and, accordingly, the applicable
condition has been satisfied. For the avoidance of doubt, the condition shall only be deemed satisfied if so publicly disclosed as such, and upon public disclosure that the transaction has not been consummated and the condition has not been
satisfied, any conversion that is conditional upon such condition being satisfied shall be null and void and of no force or effect. The failure to pay in full the amount payable to the Holder on the Optional Redemption Date and to issue a Warrant to
the Holder in accordance with Section 2.9 of the Facility Agreement shall constitute an Event of Default under the Facility Agreement. For the avoidance of doubt, the Holder may convert all or any portion of this Note into Shares in accordance
with Section 2 at any time and from time to time during each Pending Redemption Period. In the event that an Optional Redemption is conditional upon the consummation of a specified transaction, each Conversion Notice delivered during the
Pending Redemption Period applicable to such Optional Redemption may, at the Holder’s election, specify that the conversion of this Note contemplated thereby shall be conditional upon the consummation of such specified transaction, in which
case, such conversion shall be effective upon the consummation of such transaction and, notwithstanding anything to the contrary contained herein, the Conversion Date with respect thereto shall be the date such transaction is consummated. If the
Principal Redemption Amount specified in an Optional Redemption Notice is less than the entire Principal amount, the Principal amount specified in each Conversion Notice delivered by the Holder during the Pending Redemption Period in respect of such
Optional Redemption Notice (a “Redemption Period Conversion Amount”) shall be applied (i) first, to reduce, on a dollar-for-dollar basis, the
Principal amount of this Note in excess of the Principal Redemption Amount until such excess Principal amount is reduced to zero dollars ($0) and (ii) thereafter, to reduce, on a
dollar-for-dollar basis, the Principal Redemption Amount until all of such Principal Redemption Amount shall have been converted. 

  
 19 













 Execution Version 

 

 (d) Notwithstanding anything to the contrary contained herein, without the prior written
consent of the Required Note Holders, the Company shall not deliver an Optional Redemption Notice, and the Company shall not affect any Optional Redemption, (i) during the occurrence of a Delisting Event, (ii) unless all Conversion Shares,
including Additional Conversion Shares, and all Warrant Shares will constitute Freely Tradeable Shares, as applicable, upon the issuance thereof and the representations and warranties set forth in the Warrant shall be true and correct in all
respects, (iii) unless the Stockholder Approval shall have been obtained, the Charter Effective Time and any Reverse Split Effective Time shall have occurred and there shall be sufficient authorized, unissued and unreserved (other than for
issuance pursuant to the Convertible Notes and the Warrants) Shares to provide for the issuance of the maximum total number of Shares (including Additional Shares) that are then issuable or may thereafter become issuable upon conversion of the
Convertible Notes and the exercise in full of the Warrants (in each case, without regard to the Beneficial Ownership Cap, the Cap Allocation Amount, the existence of the Authorized Share Conversion Restriction Period and any other limitations on
conversion herein or elsewhere and without regard to whether or not a sufficient number of shares are authorized, reserved and available to effect any such conversion and issuance), (iv) if the Transfer Agent for the Common Stock is not
participating in DTC’s Fast Automated Securities Transfer Program, (v) if a Conversion Failure shall have occurred and be continuing, or (vi) if the Optional Redemption is conditional upon the consummation of a transaction, unless the
Company has entered into a binding agreement with respect to such transaction or, in the case of a financing transaction, has received a binding commitment letter in customary form with respect to such financing transaction (collectively, the
“Redemption Conditions”), except to the extent the Required Note Holders have waived any such Redemption Condition by written notice to the Company. The Company covenants that no information contained in any Optional Redemption
Notice will constitute, and the delivery of an Optional Redemption Notice will not constitute, material non-public information. If any of the Redemption Conditions is not satisfied at any time following the
delivery of an Optional Redemption Notice and prior to the Optional Redemption Date in respect of Optional Redemption, the Company shall immediately notify the Holder of such failure and (regardless of whether the Company shall have notified the
Holder of such failure), by written notice delivered by the Holder to the Company at any time prior to the Optional Redemption Date, the Required Note Holders may elect to terminate the Pending Redemption Period, whereupon the Optional Redemption
Notice shall be voided, the Pending Redemption Period shall cease, and the Optional Redemption shall not be effected. 
 8. Certain
Provisions Related to Common Stock Issued Hereunder. 
 (a) Sufficient Shares of Common Stock. Except to the extent otherwise
provided in Section 5.21 of the Facility Agreement, the Company shall provide, free from preemptive rights, out of the Company’s authorized but unissued shares or shares held in treasury, sufficient shares of Common Stock to provide for
conversion of the Notes held by the Holder from time to time as such Notes are presented for conversion (assuming that at the time of computation of such number of shares of Common Stock, all such Notes would be converted by the Holder into
Conversion Shares (without regard to the Beneficial Ownership Cap)). If at any time the number of authorized but unissued shares of Common Stock shall not be sufficient to effect the conversion of the entire Principal convertible under this Note
(other than to the extent permitted by Section 5.21 of the Facility Agreement), the Company will use reasonable best efforts to take such corporate action 

  
 20 













 Execution Version 

 

 
as may be necessary to increase its authorized but unissued shares of Common Stock to such number of shares as shall be sufficient for such purpose, including, without limitation, calling a
special meeting of stockholders and/or any other relevant corporate body to amend the Company’s charter increasing the authorized share capital of the sufficiently high to meet the Company’s obligations under this Section 8(a). 

(b) Fully-Paid. The Company covenants that all shares of Common Stock issued upon conversion of Notes held by the Holder will be fully
paid by the Company and free from all taxes, liens and charges with respect to the issue thereof. 
 9. Amendment; Waiver. The terms
and provisions of this Note shall not be amended or waived except in a writing signed by the Company and the Required Note Holders. 
 10.
Remedies, Characterizations, Other Obligations, Breaches and Injunctive Relief. The remedies provided in this Note shall be cumulative and in addition to all other remedies available under this Note, the Facility Agreement, at law or in
equity (including a decree of specific performance and/or other injunctive relief). No remedy contained herein shall be deemed a waiver of compliance with the provisions giving rise to such remedy, and nothing herein shall limit the Holder’s
right to pursue actual damages for any failure by the Company to comply with the terms of this Note. The Company covenants to the Holder that there shall be no characterization concerning this instrument other than as expressly provided herein. The
Company acknowledges that a breach by it of its obligations hereunder will cause irreparable harm to the Holder and that the remedy at law for any such breach may be inadequate. The Company therefore agrees that, in the event of any such breach or
threatened breach, the Holder shall be entitled, in addition to all other available remedies, to an injunction restraining any breach, without the necessity of showing economic loss and without any bond or other security being required. 

11. Specific Shall Not Limit General; Construction. No specific provision contained in this Note shall limit or modify any more general
provision contained herein. This Note shall be deemed to be jointly drafted by the Company and all purchasers of Notes pursuant to the Facility Agreement and shall not be construed against any Person as the drafter hereof. 

12. Failure or Indulgence Not Waiver. No failure or delay on the part of the Holder in the exercise of any power, right or privilege
hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such power, right or privilege preclude other or further exercise thereof or of any other right, power or privilege. 

13. Notices. Whenever notice is required to be given under this Note, unless otherwise provided herein, such notice shall be given in
accordance with Section 8.1 of the Facility Agreement. 
 14. Restrictions on Transfer. 

(a) Registration or Exemption Required. This Note has been issued in a transaction exempt from the registration requirements of the
Securities Act by virtue of Regulation D under the Securities Act. None of the Note or the Conversion Shares may be pledged, transferred, sold, assigned, hypothecated or otherwise disposed of except pursuant to an effective registration statement or
an exemption to the registration requirements of the Securities Act and applicable state laws

 Execution Version 

 

 
including, without limitation, pursuant to Rule 144 (or, in the case of this Note, Rule 144A) under the Securities Act or pursuant to a private sale effected under Section 4(a)(7) of the
Securities Act or applicable formal or informal SEC interpretation or guidance, such as a so-called “4(a)(1) and a half” transaction. 

(b) Assignment. Subject to Section 13(a), the Holder may sell, transfer, assign, pledge, hypothecate or
otherwise dispose of this Note, in whole or in part. Holder shall deliver a written notice to Company, substantially in the form of the Assignment attached hereto as Exhibit B, indicating the Person or Persons to whom the Note shall be
assigned and the respective principal amount of the Note to be assigned to each assignee. The Company shall effect the assignment within five (5) Trading Days (the “Transfer Delivery Period”), and shall deliver to the
assignee(s) designated by Holder a Note or Notes of like tenor and terms for the appropriate principal amount. This Note and the rights evidenced hereby shall inure to the benefit of and be binding upon the successors and permitted assigns of the
Holder. The provisions of this Note are intended to be for the benefit of all Holders from time to time of this Note, and shall be enforceable by any such Holder. For avoidance of doubt, in the event Holder notifies the Company that such sale or
transfer is a so called “4(a)(1) and half” transaction, the parties hereto agree that a legal opinion from outside counsel for the Holder delivered to counsel for the Company substantially in the form attached hereto as Exhibit C
shall be the only requirement to satisfy an exemption from registration under the Securities Act to effectuate such “4(a)(1) and half” transaction. 

15. Obligations of the Company. For so long as any conversion rights under this Note remain capable of being exercised, the Company
will (a) keep available for issue out of its authorized but unissued shares capital free from pre-emptive rights such number of shares of Common Stock as would enable the Conversion Shares to be issued in
full, and (b) will not, without the consent of the Holder, make any alteration to its certificate of incorporation which could have a material adverse effect on the rights attaching to the Common Stock or the rights of the Holder; provided that
alterations to (i) increase the number of authorized shares of Common Stock, (ii) provide the terms for and issue shares of preferred stock of the Company or (iii) effect a stock split of the Common Stock shall not be deemed to have a
material adverse effect on the rights attaching to the Common Stock or the rights of the Holder. 
 16. Payment of Collection,
Enforcement and Other Costs. If (a) this Note is placed in the hands of an attorney for collection or enforcement or is collected or enforced through any legal proceeding; or (b) an attorney is retained to represent the Holder in any
bankruptcy, reorganization, receivership of the Company or other proceedings affecting Company creditors’ rights and involving a claim under this Note, then the Company shall pay the costs incurred by the Holder for such collection, enforcement
or action, including reasonable attorneys’ fees and disbursements. 
 17. Cancellation. After all Principal, Interest and other
amounts at any time owed under, or on account of, this Note have been paid in full or converted into Shares in accordance with the terms hereof, this Note shall automatically be deemed cancelled, shall be surrendered to the Company for cancellation
and shall not be reissued. 
 18. Registered Note. In order to qualify as a “registered note” for purposes of the Code,
transfer of this Note may be effected only by (i) surrender of this Note to the Company and the re-issuance of this Note to the transferee, or the Company’s issuance to the Holder of a new note in
the same 

  
 22 













 Execution Version 

 

 
form as this Note but with the transferee denoted as the Holder, or (ii) the recording of the identity of the transferee by the Affiliate of the Holder that is maintaining a record ownership
register of this Note as a non-fiduciary agent of, and on behalf of, the Company for the tax purposes set forth herein. Such Affiliate in its capacity as such agent shall notify the Company in writing
immediately upon any change in such identity. Any attempted transfer in violation of the relevant provisions of this Note shall be void and of no force and effect. Until there has been a valid transfer of this Note and of all of the rights hereunder
by the Holder in accordance with this Note, the Company shall deem and treat the Holder as the absolute beneficial owner and holder of this Note and of all of the rights hereunder for all purposes (including, without limitation, for the purpose of
receiving all payments to be made under this Note). 
 19. Waiver of Notice. To the extent permitted by law, the Company hereby
waives demand, notice, presentment, protest and all other demands and notices in connection with the delivery, acceptance, performance, default or enforcement of this Note and the Facility Agreement. 

20. Governing Law. This Note shall be construed and enforced in accordance with, and all questions concerning the construction,
validity, interpretation and performance of this Note and all disputes arising hereunder shall be governed by, the laws of the State of Delaware, without giving effect to any choice of law or conflict of law provision or rule (whether of the State
of Delaware or any other jurisdictions) that would cause the application of the laws of any jurisdictions other than the State of Delaware. The Company (a) agrees that any legal action or proceeding with respect to this Note or any other
agreement, document, or other instrument executed in connection herewith, shall be brought exclusively in any state or federal court located within Wilmington, Delaware, (b) irrevocably waives any objections which the Company may now or
hereafter have to the venue of any suit, action or proceeding arising out of or relating to this Note, or any other agreement, document, or other instrument executed in connection herewith, brought in the aforementioned courts, (c) further
irrevocably waives any claim that any such suit, action, or proceeding brought in any such court has been brought in an inconvenient forum and (d) hereby consents that personal service of summons or other legal process may be made as set forth
in Section 8.3 of the Facility Agreement. EACH OF THE COMPANY AND THE HOLDER (BY ACCEPTANCE HEREOF) IRREVOCABLY WAIVES THE RIGHT TO A TRIAL BY JURY IN ANY ACTION OR PROCEEDING BROUGHT TO ENFORCE ANY PROVISION OF THIS NOTE OR ANY OTHER FACILITY
DOCUMENT. 
 20. Interpretative Matters. Unless the context otherwise requires, (a) all references to Sections or Exhibits are
to Sections or Exhibits contained in or attached to this Note, (b) each accounting term not otherwise defined in this Note has the meaning assigned to it in accordance with GAAP, (c) words in the singular or plural include the singular and
plural and pronouns stated in either the masculine, the feminine or neuter gender shall include the masculine, feminine and neuter and (d) the use of the word “including” in this Note shall be by way of example rather than limitation.
If a stock split, stock dividend, stock combination or other similar event occurs during any period over which an average price is being determined, then an appropriate adjustment will be made to such average to reflect such event. All cash payments
to be made pursuant to this Note shall be made in Dollars. In connection with any conversion or assignment of this Note, no ink-original Conversion Notice or instrument of assignment or transfer, as
applicable, shall be required, nor 

  
 23

shall any medallion guarantee (or other type of guarantee or notarization) of any Conversion Notice, other notice hereunder or instrument of assignment or transfer be required. 

21. Execution. A facsimile, telecopy, PDF or other reproduction of this Note may be delivered by the Company, and an executed copy of
this Note may be delivered by the Company by facsimile, electronic mail or other similar electronic transmission device pursuant to which the signature of or on behalf of the Company can be seen, and such execution and delivery shall be considered
valid, binding and effective for all purposes. The Company hereby agrees that it shall not raise the execution of facsimile, PDF or other reproduction of this Note, or the fact that any signature was transmitted by facsimile, electronic mail or
other similar electronic transmission device, as a defense to the Company’s execution of this Note. Notwithstanding the foregoing, the Company shall be required to deliver an originally executed Note to the Holder.

 Exhibit C 

FORM OF OPINION 

___________, 20__

[_______________] (“[__________]”) intends to transfer its Convertible Note in the principal amount of $____________ (the “Note”) of the

order. 
 The foregoing opinion is furnished only to ____________ and may not be used, circulated, quoted or otherwise referred to or relied upon by you for
any purposes other than the purpose for which furnished or by any other person for any purpose, without our prior written consent. 
 Very
truly yours,

 Schedule 1 

The “Additional Share Coefficient” shall mean the number of additional shares of Common Stock issuable per $1,000 of
principal amount of the Note upon a Major Transaction and shall be the additional share number set forth on the chart with respect to the “Share Price Result” on the “y” axis and the corresponding “Remaining Note Life”
on the “x” axis; provided, however, that to the extent the actual Share Price Result (as defined below) falls between two data points on the “y” axis and/or the actual date of the Major Transaction falls between two
data points on the “x” axis, the “Additional Share Coefficient” shall be determined by calculating the arithmetic mean between (i) the result obtained for the Share Price Result based on the linear interpolation between the
additional share numbers corresponding to the two Share Price Result data points and (ii) the result obtained for the Remaining Note Life based on the linear interpolation between the two additional share numbers corresponding to the two
Remaining Note Life data points; and provided further, however, that in the event of any adjustment to the Conversion Price pursuant to Section 2 of this Note, the numbers of additional shares of Common Stock issuable per
$1,000 of principal amount of this Note as set forth in the chart below shall be deemed adjusted pro rata with any adjustment resulting from the adjustment to the Conversion Price that would be made to the number of shares of Common Stock then
convertible with respect to $1,000 of principal amount of this Note as calculated under Section 2 of this Note. For purposes of the chart below, the “Share Price Result” shall be the greater of: (i) the last sales price of shares
of Common Stock on the NASDAQ Global Select Market, or, if that is not the principal trading market for shares of Common Stock, such principal market on which shares of Common Stock are traded or listed (the “Closing Market Price”)
immediately prior to the consummation of the Major Transaction or (ii) in the case of a Major Transaction in which holders of shares of Common Stock receive solely cash consideration in connection with such major Transaction, the cash amount
payable per share of Common Stock in such Major Transaction. If the actual Share Price Result is greater than $30.00 per share (subject to adjustment in the same manner as the Conversion Price as provided in Section 2 of this Note), or if the
actual Shares Price Result is less than $1.50 per share (subject to adjustment in the same manner as the Conversion Price as provided in Section 2 of this Note), then no additional shares shall be issuable.
