	 Issuance Date: June 30, 2014

Exchange Date: April 2, 2015
				 Original Principal Amount:

U.S. $797,649.54


 FOR VALUE RECEIVED, Amedica Corporation, a Delaware corporation (the
“Company”), hereby promises to pay to the order of MG Partners II, Ltd. or its registered assigns (“Holder”) the amount set out above as the Original Principal Amount (as reduced pursuant to the terms
hereof pursuant to redemption, conversion or otherwise, the “Principal”) when due, whether upon the Maturity Date (as defined below), acceleration, redemption or otherwise (in each case in accordance with the terms hereof)
and to pay interest (“Interest”) on any outstanding Principal (as defined below) (as such interest on any outstanding Principal may be reduced pursuant to the terms hereof pursuant to redemption, conversion or otherwise) at
the applicable Interest Rate (as defined below) from the date set out above as the Issuance Date (the “Issuance Date”) until the same becomes due and payable, whether upon the Maturity Date or acceleration, conversion,
redemption or otherwise (in each case in accordance with the terms hereof). This Senior Convertible Note (this “Note”, including all Senior Convertible Notes issued in exchange, transfer or replacement hereof, collectively,
the “Notes”) is one of a series of Senior Convertible Notes issued pursuant to an Amendment and Exchange Agreement, dated as of April 






 
2, 2015, by and between the Holder and the Company (the “Exchange Agreement”) in exchange for the Existing Warrant (as defined in the Exchange Agreement) and the
outstanding Senior Convertible Notes, with an aggregate original principal amount of U.S.$2,900,000 and an aggregate outstanding principal amount as of the calendar day immediately preceding the Exchange Date of U.S.$797,649.54, originally issued
pursuant to the Securities Purchase Agreement (as defined below) either on the Initial Closing Date (as defined below) or, if applicable, on the Additional Closing Date (as defined below) (collectively, the “Notes” and such
other Senior Convertible Notes, the “Other Notes”). Certain capitalized terms used herein are defined in Section 28. 

1. PAYMENTS OF PRINCIPAL. On the Maturity Date, the Company shall pay to the Holder an amount in cash representing all outstanding
Principal, accrued and unpaid Interest and accrued and unpaid Late Charges (as defined in Section 23(c)) on such Principal and Interest (as adjusted with respect to any Note Reduction (as defined in Section 12)). Other than as specifically
permitted by this Note, the Company may not prepay any portion of the outstanding Principal, accrued and unpaid Interest or accrued and unpaid Late Charges on Principal and Interest, if any. 

2. INTEREST; INTEREST RATE. 

(a) Interest on this Note shall commence accruing on the Issuance Date and shall be computed on the basis of a 360-day year and twelve 30-day
months and shall be payable in cash on the Maturity Date or any applicable Redemption Date, subject to adjustment with respect to any Note Reduction. 

(b) Prior to the payment of Interest on the Maturity Date or any applicable Redemption Date, Interest on this Note shall accrue at the
Interest Rate and be payable by way of inclusion of the Interest in the Conversion Amount on each Conversion Date in accordance with Section 3(b)(i). From and after the occurrence and during the continuance of any Event of Default, the Interest
Rate shall automatically be increased to eighteen percent (18.0%) per annum. In the event that such Event of Default is subsequently cured, the adjustment referred to in the preceding sentence shall cease to be effective as of the calendar day
immediately following the date of such cure; provided that the Interest as calculated and unpaid at such increased rate during the continuance of such Event of Default shall continue to apply to the extent relating to the days after the occurrence
of such Event of Default through and including the date of such cure of such Event of Default. 
 3. CONVERSION OF NOTES. This Note
shall be convertible into validly issued, fully paid and non-assessable shares of Common Stock (as defined below), on the terms and conditions set forth in this Section 3. 

(a) Conversion Right. Subject to the provisions of Section 3(d), at any time or times on or after the Issuance Date, the Holder
shall be entitled to convert any portion of the outstanding and unpaid Conversion Amount (as defined below) into validly issued, fully paid and non-assessable shares of Common Stock in accordance with Section 3(c), at the Conversion Rate (as
defined below). The Company shall not issue any fraction of a share of Common Stock upon any conversion. If the issuance would result in the issuance of a fraction of a share of 

  
 2 







 
Common Stock, the Company shall round such fraction of a share of Common Stock up to the nearest whole share. The Company shall pay any and all transfer, stamp, issuance and similar taxes that
may be payable with respect to the issuance and delivery of Common Stock upon conversion of any Conversion Amount. 
 (b) Conversion
Rate. The number of shares of Common Stock issuable upon conversion of any Conversion Amount pursuant to Section 3(a) shall be determined by dividing (x) such Conversion Amount by (y) the Conversion Price (the
“Conversion Rate”). 
 (i) “Conversion Amount” means the portion of the
Principal to be converted, redeemed or otherwise with respect to which this determination is being made, plus all accrued and unpaid Interest with respect to such portion of the Principal amount and accrued and unpaid Late Charges with respect to
such portion of such Principal and such Interest. 
 (ii) “Conversion Price” means, for any date of
determination, $1.00, (as adjusted for stock splits, stock dividends, stock combinations or other similar transactions); provided, that if on May 29, 2015 (the “Adjustment Date”), 120% of the quotient of (x) the sum
of the VWAP of the Common Stock of each Trading Day during the five (5) Trading Day period ending on and including the Trading Day immediately prior to the Adjustment Date, divided by (y) five (5) (the “Adjustment
Price”) is greater than $1.00, the Conversion Price then in effect shall be the Adjustment Price. 
 (c) Mechanics of
Conversion. 
 (i) Optional Conversion. To convert any Conversion Amount into shares of Common Stock on any date
(a “Conversion Date”), the Holder shall deliver (whether via facsimile or otherwise), for receipt on or prior to 11:59 p.m., New York time, on such date, a copy of an executed notice of conversion in the form attached hereto
as Exhibit I (the “Conversion Notice”) to the Company. If required by Section 3(c)(iii), the Holder shall surrender this Note to a nationally recognized overnight delivery service for delivery to the Company (or
an indemnification undertaking with respect to this Note in the case of its loss, theft or destruction as contemplated by Section 17(b)). On or before the first (1st) Trading Day
following the date of receipt of a Conversion Notice, the Company shall transmit by facsimile an acknowledgment of confirmation, in the form attached hereto as Exhibit II, of receipt of such Conversion Notice to the Holder and the
Company’s transfer agent (the “Transfer Agent”) . On or before the second (2nd) Trading Day following the date of receipt of a Conversion Notice, the Company
shall (1) provided that the Transfer Agent is participating in The Depository Trust Company’s (“DTC”) Fast Automated Securities Transfer Program and such shares of Common Stock may be issued without restrictive
legend in accordance with Section 4.4 of the Securities Purchase Agreement, credit such aggregate number of shares of Common Stock to which the Holder shall be entitled to the Holder’s or its designee’s balance account with DTC
through its Deposit/Withdrawal at Custodian system or (2) if the Transfer Agent is not participating in the DTC Fast Automated Securities Transfer Program or such 

  
 3 







 
shares of Common Stock may not be issued without restrictive legend in accordance with Section 4.4 of the Securities Purchase Agreement, issue and deliver (via reputable overnight courier)
to the address as specified in the Conversion Notice, a certificate, registered in the name of the Holder or its designee, for the number of shares of Common Stock to which the Holder shall be entitled. If this Note is physically surrendered for
conversion as required by Section 3(c)(iii) and the outstanding Principal of this Note is greater than the Principal portion of the Conversion Amount 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 and at its own expense, issue and deliver to the Holder (or its designee) a new Note (in accordance with Section 17(d)) representing the outstanding Principal not converted. The Person or
Persons entitled to receive the shares of Common Stock issuable upon a conversion of this Note shall be treated for all purposes as the record holder or holders of such shares of Common Stock on the Conversion Date. 

(ii) Company’s Failure to Timely Convert. If the Company shall fail, for any reason or for no reason, to issue to
the Holder within three (3) Trading Days after the Company’s receipt of a Conversion Notice (whether via facsimile or otherwise) (the “Share Delivery Deadline”), a certificate for the number of shares of Common
Stock to which the Holder is entitled and register such shares of Common Stock on the Company’s share register or to credit the Holder’s or its designee’s balance account with DTC for such number of shares of Common Stock to which the
Holder is entitled upon the Holder’s conversion of any Conversion Amount (as the case may be) (a “Conversion Failure”) then, in addition to all other remedies available to the Holder, (1) the Company shall pay in
cash to the Holder on each day after such Share Delivery Deadline that the issuance of such shares of Common Stock is not timely effected an amount equal to 2% of the product of (A) the sum of the number of shares of Common Stock not issued to
the Holder on a timely basis and to which the Holder is entitled multiplied by (B) the Closing Sale Price of the Common Stock on the Trading Day immediately preceding the last possible date which the Company could have issued such shares of
Common Stock to the Holder without violating Section 3(c)(i) and (2) the Holder, upon written notice to the Company, may void its Conversion Notice with respect to, and retain or have returned (as the case may be) any portion of this Note
that has not been converted pursuant to such Conversion Notice, provided that the voiding of a Conversion Notice shall not affect the Company’s obligations to make any payments which have accrued prior to the date of such notice pursuant to
this Section 3(c)(ii) or otherwise. In addition to the foregoing, if on or prior to the Share Delivery Deadline, the Company shall fail to issue and deliver a certificate to the Holder and register such shares of Common Stock on the
Company’s share register or credit the Holder’s or its designee’s balance account with DTC for the number of shares of Common Stock to which the Holder is entitled upon the Holder’s conversion hereunder (as the case may be), and
if on or after such Share Delivery Deadline the Holder purchases (in an open market transaction or otherwise) shares of Common Stock to deliver in satisfaction of a sale by the Holder of all or any portion of the number of shares of Common Stock, or
a sale of a number of shares of Common Stock equal to all or any portion of the number of shares of Common Stock, issuable upon such conversion that the Holder 

  
 4 







 
so anticipated receiving from the Company, then, in addition to all other remedies available to the Holder, the Company shall, within three (3) Business Days after receipt of the
Holder’s request and in the Holder’s discretion, either: (I) pay cash to the Holder in an amount equal to the Holder’s total purchase price (including brokerage commissions and other out-of-pocket expenses, if any) for the shares
of Common Stock so purchased (including, without limitation, by any other Person in respect, or on behalf, of the Holder) (the “Buy-In Price”), at which point the Company’s obligation to so issue and deliver such
certificate or credit the Holder’s balance account with DTC for the number of shares of Common Stock to which the Holder is entitled upon the Holder’s conversion hereunder (as the case may be) (and to issue such shares of Common Stock)
shall terminate, or (II) promptly honor its obligation to so issue and deliver to the Holder a certificate or certificates representing such shares of Common Stock or credit the Holder’s balance account with DTC for the number of shares of
Common Stock to which the Holder is entitled upon the Holder’s conversion hereunder (as the case may be) and pay cash to the Holder in an amount equal to the excess (if any) of the Buy-In Price over the product of (x) such number of shares
of Common Stock multiplied by (y) the lowest Closing Sale Price of the Common Stock on any Trading Day during the period commencing on the date of the applicable Conversion Notice and ending on the date of such issuance and payment under this
clause (II). This Section 3(c)(ii) shall not be applicable to a Conversion Failure due solely to an Authorized Share Failure (as defined in Section 8(b)), in which case the provisions of Section 8(b) shall be applicable. 

(iii) Book-Entry. Notwithstanding anything to the contrary set forth in this Section 3, following conversion of any
portion of this Note in accordance with the terms hereof, the Holder shall not be required to physically surrender this Note to the Company unless (A) the full Conversion Amount represented by this Note is being converted (in which event this
Note shall be delivered to the Company following conversion thereof as contemplated by Section 3(c)(i)) or (B) the Holder has provided the Company with prior written notice (which notice may be included in a Conversion Notice) requesting
reissuance of this Note upon physical surrender of this Note. The Holder and the Company shall maintain records showing the Principal, Interest and Late Charges converted and/or paid and/or adjusted (as the case may be) and the dates of such
conversions and/or payments and/or adjustments (as the case may be) 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 conversion. 

(iv) Pro Rata Conversion; Disputes. In the event of a dispute as to the number of shares of Common Stock issuable to the
Holder in connection with a conversion of this Note, the Company shall issue to the Holder the number of shares of Common Stock not in dispute and resolve such dispute in accordance with Section 22. 

(v) Make-Whole Shares. Upon any conversion of this Note hereunder (whether pursuant to Section 3(c),
Section 3(e) or otherwise hereunder) at a Conversion Price or Alternate Conversion Price, as applicable, both (x) less than or 

  
 5 







 
equal to $0.20 (as adjusted for stock splits, stock dividends, recapitalizations and similar events) and (y) greater than the Closing Bid Price as of the Trading Day immediately preceding
such applicable Conversion Date (each, a “Make-Whole Eligible Conversion”), the Holder shall be entitled to additional shares of Common Stock in accordance with this Section 3(c)(v) as follows: 

(A) Mechanics. At any time after the Holder shall have sold all shares of Common Stock issued in a Make-Whole Eligible
Conversion (each, a “Make-Whole Eligibility Time”), the Holder may deliver a written notice to the Company (each, a “Make-Whole Eligibility Notice”, and such date, a “Make-Whole Eligibility
Notice Date”) certifying that the Holder is entitled to receive additional shares of Common Stock (the “Make-Whole Shares”) pursuant to this Section 3(c)(v). The Make-Whole Eligibility Notice shall set forth
(x) the number of Make-Whole Shares to be issued to the Holder in accordance with Section 3(c)(v)(B) below, (y) the Make-Whole Consideration (as defined below) and (z) the aggregate Make-Whole Consideration received by the Holder
with respect to all conversions in such Make-Whole Quarter. On the Trading Day immediately following each Make-Whole Quarter, the Company shall deliver a written notice to the Holder setting forth the number of Make-Whole Shares to be delivered on
the related Make-Whole Shares Delivery Date (as defined below) (together with reasonable calculations with respect thereto). The Company shall issue such Make-Whole Shares to the Holder on the third (3) Trading Day after each Make-Whole
Quarter, beginning June 30, 2015 (the “Make-Whole Shares Delivery Date”); provided, that (x) if the aggregate Make-Whole Consideration of all conversions set forth in each Make-Whole Eligibility Notice
delivered in such Make-Whole Quarter is greater than or equal to the aggregate Conversion Amount of such conversions described in each such Make-Whole Eligibility Notice delivered in such Make-Whole Quarter, the Company’s obligation to issue
such Make-Whole Shares shall terminate and (y) if the number of Make-Whole Shares to be issued to the Holder exceeds the Maximum Percentage, the Company shall hold such shares in abeyance until it receives written notice from the Holder that
the Holder is permitted to receive such Make-Whole Shares hereunder and the corresponding portion of the Make-Whole Conversion Amount (as defined below) with respect thereto shall remain outstanding hereunder. On each Make-Whole Shares Delivery
Date, the Company shall (i) (A) provided that the Transfer Agent is participating in the DTC Fast Automated Securities Transfer Program, credit such aggregate number of Make-Whole Shares to which the Holder shall be then entitled to the
Holder’s or its designee’s balance account with DTC through its Deposit/Withdrawal at Custodian system, or (B) if the Transfer Agent is not participating in the DTC Fast Automated Securities Transfer Program, issue and deliver on the
applicable Make-Whole Shares Delivery Date, to the address set forth in the register maintained by the Company for such purpose pursuant to the Securities Purchase Agreement or to such address as specified by the Holder in writing to the Company at
least two (2) Business Days prior to the applicable Make-Whole Shares Delivery Date, a certificate, registered in the name of the Holder or its designee, for the number of Make-Whole Shares to which the Holder shall be entitled. The Company
shall not issue any fraction of a share of Common 

  
 6 







 
Stock upon any issuance of Make-Whole Shares on any Make-Whole Shares Delivery Date. If such issuance would result in the issuance of a fraction of a share of Common Stock, the Company shall
round such fraction of a share of Common Stock up to the nearest whole share. In addition to Holder’s right to pursue any remedies available to it hereunder, at law or in equity, including, without limitation, a decree of specific performance
and/or injunctive relief with respect to the Company’s failure to timely deliver certificates representing Make-Whole Shares (or to electronically deliver such Make-Whole Shares), any failure by the Company to timely deliver Make-Whole Shares
to the Holder (or its designee) on a Make-Whole Shares Delivery Date shall be subject to the provisions of 3(c)(ii) above, mutatis mutandis. 

(B) Calculation of Number of Make-Whole Shares. With respect to each Make-Whole Shares Delivery Date, the number of
Make-Whole Shares issuable to the Holder shall equal the greater of (I) zero and (II) the quotient of (1) the difference (such difference, the “Make-Whole Conversion Amount”) of (x) the aggregate Conversion
Amount with respect to each conversion of this Note occurring in such Make-Whole Quarter in which such Make-Whole Shares Delivery Date occurs (excluding the aggregate Conversion Amount relating to any shares of Common Stock that have not been resold
by the Holder in such Make-Whole Quarter in which such Make-Whole Shares Delivery Date occurs) (collectively, the “Make-Whole Measuring Conversions”), minus (y) the aggregate gross consideration received by the Holder
from the resale of all shares of Common Stock issued with respect to conversions of this Note occurring in such Make-Whole Quarter including shares of Common Stock issued in such Make-Whole Eligible Conversion (the “Make-Whole
Consideration”), divided by (2) the Alternate Conversion Price as of such Make-Whole Shares Delivery Date. For the avoidance of doubt, any Make-Whole Shares issued or issuable hereunder shall be deemed to be a voluntary conversion
by the Holder of the related Make-Whole Conversion Amount as of third (3rd) Trading Day immediately prior to the applicable Make-Whole Shares Delivery Date for all purposes hereunder and
pursuant to any other Transaction Document. 
 (C) Limitations on Issuances of Make-Whole Shares. Notwithstanding
anything in this Section 3(c) to the contrary, if as of any given date the aggregate gross consideration received by the Holder from the resale of shares of Common Stock issued hereunder prior to such given date exceeds the sum of
(x) $[PRINCIPAL] and (y) the sum of all accrued and unpaid interest hereunder through and including such given date, no additional Make-Whole Shares shall be issuable hereunder. 

(d) Limitations on Conversions. Notwithstanding anything to the contrary contained in this Note, this Note shall not be convertible by
the Holder hereof, and the Company shall not effect any conversion of this Note or otherwise issue any shares of Common Stock pursuant hereto, to the extent (but only to the extent) that after giving effect to such conversion or other share issuance
hereunder the Holder (together with its affiliates) would beneficially own in excess of 4.99% (the “Maximum Percentage”) of the Common Stock. To the extent the 

  
 7 







 
above limitation applies, the determination of whether this Note shall be convertible (vis-à-vis other convertible, exercisable or exchangeable securities owned by the Holder or any of its
affiliates) and of which such securities shall be convertible, exercisable or exchangeable (as among all such securities owned by the Holder and its affiliates) shall, subject to such Maximum Percentage limitation, be determined on the basis of the
first submission to the Company for conversion, exercise or exchange (as the case may be). No prior inability to convert this Note, or to issue shares of Common Stock, pursuant to this paragraph shall have any effect on the applicability of the
provisions of this paragraph with respect to any subsequent determination of convertibility. For purposes of this paragraph, beneficial ownership and all determinations and calculations (including, without limitation, with respect to calculations of
percentage ownership) shall be determined in accordance with Section 13(d) of the 1934 Act (as defined in the Securities Purchase Agreement) and the rules and regulations promulgated thereunder. The provisions of this paragraph shall be
implemented in a manner otherwise than in strict conformity with the terms of this paragraph to correct this paragraph (or any portion hereof) which may be defective or inconsistent with the intended Maximum Percentage beneficial ownership
limitation herein contained or to make changes or supplements necessary or desirable to properly give effect to such Maximum Percentage limitation. The limitations contained in this paragraph shall apply to a successor Holder of this Note. The
holders of Common Stock shall be third party beneficiaries of this paragraph and the Company may not waive this paragraph without the consent of holders of a majority of its Common Stock. For any reason at any time, upon the written or oral request
of the Holder, the Company shall within one (1) Business Day confirm orally and in writing to the Holder the number of shares of Common Stock then outstanding, including by virtue of any prior conversion or exercise of convertible or
exercisable securities into Common Stock, including, without limitation, pursuant to this Note or securities issued pursuant to the Securities Purchase Agreement. By written notice to the Company, at any time the Holder may increase or decrease the
Maximum Percentage to any other percentage not in excess of 9.99% specified in such notice; provided that (i) any such increase will not be effective until the 61st day after such notice is delivered to the Company, and (ii) any such
increase or decrease will apply only to the Holder sending such notice and not to any other holder of Notes. 
 (e) Company Alternate
Redemption/Holder Alternate Conversion. 
 (i) Company Alternate Redemption. Notwithstanding anything herein to
the contrary, if at any time on or after the Issuance Date, the Closing Sale Price of the Common Stock is less than $4.13 (as adjusted for stock splits, stock dividends, recapitalizations and similar events) for a period of two (2) consecutive
Trading Days (the “Company Alternate Redemption Eligibility Date”), the Company may, at its sole option, redeem all, but not less than all, of the outstanding Conversion Amount of this Note (the “Company Alternate
Redemption Amount”) at a redemption price (the “Company Alternate Redemption Price”) equal to 127.5% of such Company Alternate Redemption Amount at anytime on or before the sixtieth (60th) day after the Company Alternate Redemption Eligibility Date. Redemptions required by this Section 3(e) shall be made in accordance with the provisions of Section 10. To the extent
redemptions required by this Section 3(e) are deemed or determined by a court of competent jurisdiction to be prepayments of this Note by the Company, such redemptions shall be deemed to be voluntary prepayments. Notwithstanding anything to the
contrary in this 

  
 8 







 
Section 3(e), but subject to Section 3(d), until the Company Alternate Redemption Price (together with any Late Charges thereon) is paid in full, the Company Alternate Redemption Amount
(together with any Late Charges thereon) may be converted, in whole or in part, by the Holder into Common Stock pursuant to the terms of this Note. In the event of the Company’s redemption of any portion of this Note under this
Section 3(e), the Holder’s damages would be uncertain and difficult to estimate because of the parties’ inability to predict future interest rates and the uncertainty of the availability of a suitable substitute investment opportunity
for the Holder. Accordingly, any redemption premium due under this Section 3(e) is intended by the parties to be, and shall be deemed, a reasonable estimate of the Holder’s actual loss of its investment opportunity and not as a penalty.

 (ii) Holder Alternate Conversion. If on the sixtieth
(60th) Trading Day after the Company Alternate Redemption Eligibility Date (the “Alternate Conversion Eligibility Date”) the Company has not exercised its right
pursuant to Section 3(e)(i) and paid the Company Alternate Redemption Price, the Holder may convert all, or any part, of the Conversion Amount of this Note (each, an “Holder Alternate Conversion Amount”, and each such
conversion, a “Holder Alternate Conversion”) pursuant to Section 3(c) (with “Alternate Conversion Price” replacing “Conversion Price” for all purposes hereunder with respect to such Holder Alternate
Conversion) by designating in the Conversion Notice delivered pursuant to Section 3(c) that the Holder is electing to use the Alternate Conversion Price for such conversion. 

(f) NASDAQ Share Cap. Notwithstanding anything contained herein or in any other Transaction Document (as defined in the Securities
Purchase Agreement) to the contrary, until Stockholder Approval (as defined in the Securities Purchase Agreement) is obtained, the Company shall not issue shares of Common Stock to the Holder pursuant to the Transaction Documents, including the
issuance of Commitment Shares (as defined in the Securities Purchase Agreement), Warrant Shares (as defined in the Securities Purchase Agreement) and shares of Common Stock to which the Holder is entitled upon conversion of this Note in an aggregate
amount in excess of 19.99% of the issued and outstanding Common Stock on the Issuance Date. 
 4. RIGHTS UPON EVENT OF DEFAULT. 

(a) Event of Default. Each of the following events shall constitute an “Event of Default”: 

(i) the suspension from trading or the failure of the Common Stock to be trading or listed (as applicable) on an Eligible
Market for a period of ten (10) consecutive days or for more than an aggregate of thirty (30) days in any 365-day period; 

(ii) the Company’s or any Subsidiary’s (as defined in the Securities Purchase Agreement) failure to pay to the Holder
any amount of Principal, Interest, Late Charges or other amounts when and as due under this Note (including, without limitation, the Company’s or any Subsidiary’s failure to pay any redemption


  
 9 







 
payments or amounts hereunder) or any other Transaction Document (as defined in the Securities Purchase Agreement) or any other agreement, document, certificate or other instrument delivered in
connection with the transactions contemplated hereby and thereby, except, in the case of a failure to pay Interest and Late Charges when and as due, in which case only if such failure remains uncured for a period of at least ten (10) days; 

(iii) the occurrence of any default under, redemption of or acceleration prior to maturity of an aggregate of any Indebtedness
(as defined in the Securities Purchase Agreement) of the Company or any of its Subsidiaries, in which case only if such failure remains uncured for a period of at least ten (10) days; 

(iv) bankruptcy, insolvency, reorganization or liquidation proceedings or other proceedings for the relief of debtors shall be
instituted by or against the Company or any Subsidiary and, if instituted against the Company or any Subsidiary by a third party, shall not be dismissed within forty-five (45) days of their initiation; 

(v) the commencement by the Company or any Subsidiary of a voluntary case or proceeding under any applicable federal, state or
foreign bankruptcy, insolvency, reorganization or other similar law or of any other case or proceeding to be adjudicated a bankrupt or insolvent, or the consent by it to the entry of a decree, order, judgment or other similar document in respect of
the Company or any Subsidiary in an involuntary case or proceeding under any applicable federal, state or foreign bankruptcy, insolvency, reorganization or other similar law or to the commencement of any bankruptcy or insolvency case or proceeding
against it, or the filing by it of a petition or answer or consent seeking reorganization or relief under any applicable federal, state or foreign law, or the consent by it to the filing of such petition or to the appointment of or taking possession
by a custodian, receiver, liquidator, assignee, trustee, sequestrator or other similar official of the Company or any Subsidiary or of any substantial part of its property, or the making by it of an assignment for the benefit of creditors, or the
execution of a composition of debts, or the occurrence of any other similar federal, state or foreign proceeding, or the admission by it in writing of its inability to pay its debts generally as they become due, the taking of corporate action by the
Company or any Subsidiary in furtherance of any such action or the taking of any action by any Person to commence a Uniform Commercial Code foreclosure sale or any other similar action under federal, state or foreign law; 

(vi) the entry by a court of (i) a decree, order, judgment or other similar document in respect of the Company or any
Subsidiary of a voluntary or involuntary case or proceeding under any applicable federal, state or foreign bankruptcy, insolvency, reorganization or other similar law or (ii) a decree, order, judgment or other similar document adjudging the
Company or any Subsidiary as bankrupt or insolvent, or approving as properly filed a petition seeking liquidation, reorganization, arrangement, adjustment or composition of or in respect of the Company or any Subsidiary under any applicable federal,
state or foreign law or (iii) a decree, order, judgment or other similar document appointing a custodian, receiver, 

  
 10 







 
liquidator, assignee, trustee, sequestrator or other similar official of the Company or any Subsidiary or of any substantial part of its property, or ordering the winding up or liquidation of its
affairs, and the continuance of any such decree, order, judgment or other similar document or any such other decree, order, judgment or other similar document unstayed and in effect for a period of thirty (30) consecutive days; 

(vii) a final judgment or judgments for the payment of money aggregating in excess of $100,000 are rendered against the Company
and/or any of its Subsidiaries and which judgments are not, within thirty (30) days after the entry thereof, bonded, discharged or stayed pending appeal, or are not discharged within forty-five (45) days after the expiration of such stay;
provided, however, any judgment which is covered by insurance or an indemnity from a credit worthy party shall not be included in calculating the $100,000 amount set forth above so long as the Company provides the Holder a written statement from
such insurer or indemnity provider (which written statement shall be reasonably satisfactory to the Holder) to the effect that such judgment is covered by insurance or an indemnity and the Company or such Subsidiary (as the case may be) will receive
the proceeds of such insurance or indemnity within thirty (30) days of the issuance of such judgment; 
 (viii) the
Company and/or any Subsidiary, individually or in the aggregate, either (i) fails to pay, when due, or within any applicable grace period, any payment with respect to any Indebtedness in excess of $100,000 due to any third party (other than,
with respect to unsecured Indebtedness only, payments contested by the Company and/or such Subsidiary (as the case may be) in good faith by proper proceedings and with respect to which adequate reserves have been set aside for the payment thereof in
accordance with GAAP) or is otherwise in breach or violation of any agreement for monies owed or owing in an amount in excess of $100,000, which breach or violation permits the other party thereto to declare a default or otherwise accelerate amounts
due thereunder, or (ii) suffer to exist any other circumstance or event that would, with or without the passage of time or the giving of notice, result in a default or event of default under any agreement binding the Company or any Subsidiary,
which default or event of default would or is likely to have a material adverse effect on the business, assets, operations (including results thereof), liabilities, properties, condition (including financial condition) or prospects of the Company or
any of its Subsidiaries, individually or in the aggregate; 
 (ix) other than as specifically set forth in another clause of
this Section 4(a), the Company or any Subsidiary breaches any representation, warranty, covenant or other term or condition of any Transaction Document, except, in the case of a breach of a covenant or other term or condition that is curable,
only if such breach remains uncured for a period of three (3) consecutive Trading Days; 
 (x) any Event of Default (as
defined in the Other Notes) occurs with respect to any Other Notes; 
 (xi) any Material Adverse Effect (as defined in the
Securities Purchase Agreement) occurs; or 

  
 11 







 (xii) any Change of Control occurs (other than a Fundamental Transaction in which
all of the requirements set forth in Section 5(a) below have been met). 
 (b) Notice of an Event of Default; Redemption Right.
Upon the occurrence of an Event of Default with respect to this Note, the Company shall within one (1) Business Day deliver written notice thereof via facsimile and overnight courier (with next day delivery specified) (an “Event of
Default Notice”) to the Holder. At any time after the earlier of the Holder’s receipt of an Event of Default Notice and the Holder becoming aware of an Event of Default, the Holder may require the Company to redeem, at any time
during the period commencing on the date the Holder first becomes aware of such Event of Default through and including the twentieth Trading Day after the later of (x) the date the Holder receives the applicable Event of Default Notice with
respect thereto and (y) the date such Event of Default has been cured, all or any portion of this Note by delivering written notice thereof (the “Event of Default Redemption Notice”) to the Company, which Event of
Default Redemption Notice shall indicate the portion of this Note the Holder is electing to redeem. Each portion of this Note subject to redemption by the Company pursuant to this Section 4(b) shall be redeemed by the Company at a price equal
to the greater of (i) the product of (A) the Conversion Amount to be redeemed multiplied by (B) the Redemption Premium and (ii) the product of (X) the Conversion Rate with respect to the Conversion Amount in effect at such
time as the Holder delivers an Event of Default Redemption Notice multiplied by (Y) the product of (1) the Redemption Premium multiplied by (2) the greatest Closing Sale Price of the Common Stock on any Trading Day during the period
commencing on the date immediately preceding such Event of Default and ending on the date the Company makes the entire payment required to be made under this Section 4(b) (the “Event of Default Redemption Price”).
Redemptions required by this Section 4(b) shall be made in accordance with the provisions of Section 10. To the extent redemptions required by this Section 4(b) are deemed or determined by a court of competent jurisdiction to be
prepayments of this Note by the Company, such redemptions shall be deemed to be voluntary prepayments. Notwithstanding anything to the contrary in this Section 4, but subject to Section 3(d), until the Event of Default Redemption Price
(together with any Late Charges thereon) is paid in full, the Conversion Amount submitted for redemption under this Section 4(b) (together with any Late Charges thereon) may be converted, in whole or in part, by the Holder into Common Stock
pursuant to the terms of this Note. In the event of the Company’s redemption of any portion of this Note under this Section 4(b), the Holder’s damages would be uncertain and difficult to estimate because of the parties’ inability
to predict future interest rates and the uncertainty of the availability of a suitable substitute investment opportunity for the Holder. Accordingly, any redemption premium due under this Section 4(b) is intended by the parties to be, and shall
be deemed, a reasonable estimate of the Holder’s actual loss of its investment opportunity and not as a penalty. 
 5. RIGHTS UPON
FUNDAMENTAL TRANSACTION; OTHER CORPORATE EVENTS. 
 (a) Assumption. The Company shall not enter into or be party to a Fundamental
Transaction unless (i) the Successor Entity assumes in writing all of the obligations of the Company under this Note and the other Transaction Documents in accordance with the provisions of this Section 5(a) pursuant to written agreements
in form and substance satisfactory 

  
 12 







 
to the Holder and approved by the Holder prior to such Fundamental Transaction, including agreements to deliver to each holder of Notes in exchange for such Notes a security of the Successor
Entity evidenced by a written instrument substantially similar in form and substance to the Notes, including, without limitation, having a principal amount and interest rate equal to the principal amounts then outstanding and the interest rates of
the Notes held by such holder, having similar conversion rights as the Notes and having similar ranking to the Notes, and satisfactory to the Holder and (ii) the Successor Entity (including its Parent Entity) is a publicly traded corporation
whose common stock is quoted on or listed for trading on an Eligible Market. Upon the occurrence of any Fundamental Transaction, the Successor Entity shall succeed to, and be substituted for (so that from and after the date of such Fundamental
Transaction, the provisions of this Note and the other Transaction Documents referring to the “Company” shall refer instead to the Successor Entity), and may exercise every right and power of the Company and shall assume all of the
obligations of the Company under this Note and the other Transaction Documents with the same effect as if such Successor Entity had been named as the Company herein. Upon consummation of a Fundamental Transaction, the Successor Entity shall deliver
to the Holder confirmation that there shall be issued upon conversion or redemption of this Note at any time after the consummation of such Fundamental Transaction, in lieu of the shares of the Company’s Common Stock (or other securities, cash,
assets or other property (except such items still issuable under Section 14, which shall continue to be receivable thereafter) issuable upon the conversion or redemption of the Notes prior to such Fundamental Transaction, such shares of the
publicly traded common stock (or their equivalent) of the Successor Entity (including its Parent Entity) which the Holder would have been entitled to receive upon the happening of such Fundamental Transaction had this Note been converted immediately
prior to such Fundamental Transaction (without regard to any limitations on the conversion of this Note), as adjusted in accordance with the provisions of this Note. Notwithstanding the foregoing, the Holder may elect, at its sole option, by
delivery of written notice to the Company to waive this Section 5(a) to permit the Fundamental Transaction without the assumption of this Note. 

(b) Other Corporate Events. In addition to and not in substitution for any other rights hereunder, prior to the consummation of any
Fundamental Transaction pursuant to which holders of shares of Common Stock are entitled to receive securities or other assets with respect to or in exchange for shares of Common Stock (a “Corporate Event”), the Company shall
make appropriate provision to insure that the Holder will thereafter have the right to receive upon a conversion of this Note (i) in addition to the shares of Common Stock receivable upon such conversion, such securities or other assets to
which the Holder would have been entitled with respect to such shares of Common Stock had such shares of Common Stock been held by the Holder upon the consummation of such Corporate Event (without taking into account any limitations or restrictions
on the convertibility of this Note) or (ii) in lieu of the shares of Common Stock otherwise receivable upon such conversion, such securities or other assets received by the holders of shares of Common Stock in connection with the consummation
of such Corporate Event in such amounts as the Holder would have been entitled to receive had this Note initially been issued with conversion rights for the form of such consideration (as opposed to shares of Common Stock) at a conversion rate for
such consideration commensurate with the Conversion Rate. Provision made pursuant to the preceding sentence shall be in a form and substance satisfactory to the Holder. 

  
 13 







 (c) The provisions of this Section 5 shall apply similarly and equally to successive
Fundamental Transactions and Corporate Events and shall be applied without regard to any limitations on the conversion of this Note. 
 6.
ADJUSTMENT OF CONVERSION PRICE. Without limiting any provision of Section 5, if the Company at any time on or after the Initial Closing Date subdivides (by any stock split, stock dividend, recapitalization or otherwise) one or more
classes of its outstanding shares of Common Stock into a greater number of shares, the Conversion Price in effect immediately prior to such subdivision will be proportionately reduced. Without limiting any provision of Section 5, if the Company
at any time on or after the Initial Closing Date combines (by combination, reverse stock split or otherwise) one or more classes of its outstanding shares of Common Stock into a smaller number of shares, the Conversion Price in effect immediately
prior to such combination will be proportionately increased. Any adjustment pursuant to this Section 6 shall become effective immediately after the effective date of such subdivision or combination. 

7. NONCIRCUMVENTION. The Company hereby covenants and agrees that the Company will not, by amendment of its certificate of
incorporation, bylaws or through any reorganization, transfer of assets, consolidation, merger, scheme of arrangement, dissolution, issue or sale of securities, or any other voluntary action, avoid or seek to avoid the observance or performance of
any of the terms of this Note, and will at all times in good faith carry out all of the provisions of this Note and take all action as may be required to protect the rights of the Holder of this Note. Without limiting the generality of the
foregoing, the Company (i) shall not increase the par value of any shares of Common Stock receivable upon conversion of this Note above the Conversion Price then in effect, (ii) shall take all such actions as may be necessary or
appropriate in order that the Company may validly and legally issue fully paid and nonassessable shares of Common Stock upon the conversion of this Note, and (iii) shall, so long as any of the Notes are outstanding, take all action necessary to
reserve and keep available out of its authorized and unissued shares of Common Stock, solely for the purpose of effecting the conversion of the Notes, the maximum number of shares of Common Stock as shall from time to time be necessary to effect the
conversion of the Notes then outstanding (without regard to any limitations on conversion). 
 8. RESERVATION OF AUTHORIZED SHARES.

 (a) Reservation. So long as any of the Notes are outstanding, the Company shall take all action necessary to reserve and keep
available out of its authorized and unissued Common Stock, solely for the purpose of effecting the conversion of the Notes, a number of shares of Common Stock, as of any date of determination, for each of the Notes in accordance with the following
formula: 
  

															
							 P
		 x 3
  
		 =
  
		 Share Reserve
  
		
							(T x B)				

 P = The aggregate outstanding Purchase Price (as defined the Securities Purchase Agreement) of the Notes issued
on or prior to such date of determination; 

  
 14 







 T = The applicable Conversion Price as of such date of determination; 

B = 0.85; 
 provided, that, the
Share Reserve shall in no event be less than 150% of the number of shares of Common Stock as shall from time to time be necessary to effect the conversion of all of the Notes then outstanding (without regard to any limitations on conversions) (the
“Required Reserve Amount”). 
 (b) Insufficient Authorized Shares. If, notwithstanding
Section 8(a), and not in limitation thereof, at any time while any of the Notes remain outstanding the Company does not have a sufficient number of authorized and unreserved shares of Common Stock to satisfy its obligation to reserve for
issuance upon conversion of the Notes at least a number of shares of Common Stock equal to the Required Reserve Amount (an “Authorized Share Failure”), then the Company shall immediately take all action necessary to increase
the Company’s authorized shares of Common Stock to an amount sufficient to allow the Company to reserve the Required Reserve Amount for the Notes then outstanding. Without limiting the generality of the foregoing sentence, as soon as
practicable after the date of the occurrence of an Authorized Share Failure, but in no event later than sixty (60) days after the occurrence of such Authorized Share Failure, the Company shall hold a meeting of its stockholders for the approval
of an increase in the number of authorized shares of Common Stock. In connection with such meeting, the Company shall provide each stockholder with a proxy statement and shall use its best efforts to solicit its stockholders’ approval of such
increase in authorized shares of Common Stock and to cause its board of directors to recommend to the stockholders that they approve such proposal. In the event that the Company is prohibited from issuing shares of Common Stock upon any conversion
due to the failure by the Company to have sufficient shares of Common Stock available out of the authorized but unissued shares of Common Stock (such unavailable number of shares of Common Stock, the “Authorization Failure
Shares”), in lieu of delivering such Authorization Failure Shares to the Holder, the Company shall pay cash in exchange for the redemption of such portion of the Conversion Amount convertible into such Authorized Failure Shares at a
price equal to the sum of (i) the product of (x) such number of Authorization Failure Shares and (y) the greatest Closing Sale Price of the Common Stock on any Trading Day during the period commencing on the date the Holder delivers
the applicable Conversion Notice with respect to such Authorization Failure Shares to the Company and ending on the date of such issuance and payment under this Section 8(b) and (ii) to the extent the Holder purchases (in an open market
transaction or otherwise) shares of Common Stock to deliver in satisfaction of a sale by the Holder of Authorization Failure Shares, any brokerage commissions and other out-of-pocket expenses, if any, of the Holder incurred in connection therewith.
Nothing contained in Section 8(a) or this Section 8(b) shall limit any obligations of the Company under any provision of the Securities Purchase Agreement. 

9. COMPANY OPTIONAL REDEMPTION. At any time after the Issuance Date, the Company shall have the right to redeem all or any portion of
the Conversion Amount then remaining under this Note (the “Company Optional Redemption Amount”) on the Company Optional Redemption Date (as defined below) (a “Company Optional Redemption”). The portion
of this Note subject to redemption pursuant to this Section 9 shall be redeemed by the Company in cash at a price (the “Company Optional Redemption Price”) equal to 127.5% of the


  
 15 







 
Company Optional Redemption Amount. The Company may exercise its right to require redemption under this Section 9 by delivering an irrevocable written notice thereof by facsimile and
overnight courier to the Holder (the “Company Optional Redemption Notice” and the date the Holder receives such notice is referred to as the “Company Optional Redemption Notice Date”). The Company may
deliver only one Company Optional Redemption Notice in any ninety (90) day period. The Company Optional Redemption Notice shall (x) state the date on which the Company Optional Redemption shall occur (the “Company Optional
Redemption Date”) which date shall not be less than sixty (60) calendar days nor more than ninety (90) calendar days following the Company Optional Redemption Notice Date, and (y) state the aggregate Conversion Amount of
the Notes which is being redeemed in such Company Optional Redemption from the Holder pursuant to this Section 9 on the Company Optional Redemption Date. Notwithstanding anything herein to the contrary, at any time prior to the date the Company
Optional Redemption Price is paid, in full, the Company Optional Redemption Amount may be converted, in whole or in part, by the Holder into shares of Common Stock pursuant to Section 3. All Conversion Amounts converted by the Holder after the
Company Optional Redemption Notice Date shall reduce the Company Optional Redemption Amount of this Note required to be redeemed on the Company Optional Redemption Date. Redemptions made pursuant to this Section 9 shall be made in accordance
with Section 10. 
 10. REDEMPTIONS. 

(a) Mechanics. The Company shall deliver the applicable Event of Default Redemption Price to the Holder in cash within five
(5) Business Days after the Company’s receipt of the Holder’s Event of Default Redemption Notice. The Company shall deliver the applicable Company Optional Redemption Price to the Holder in cash on the applicable Company Optional
Redemption Date and the Company shall deliver the Company Alternate Redemption Price to the Holder in cash on or before the Alternate Conversion Eligibility Date. In the event of a redemption of less than all of the Conversion Amount of this Note,
the Company shall promptly cause to be issued and delivered to the Holder a new Note (in accordance with Section 17(d)) representing the outstanding Principal which has not been redeemed. The Holder’s delivery of a notice voiding a
Redemption Notice and exercise of its rights following such notice shall not affect the Company’s obligations to make any payments of Late Charges which have accrued prior to the date of such notice with respect to the Conversion Amount subject
to such notice. 
 11. VOTING RIGHTS. The Holder shall have no voting rights as the holder of this Note, except as required by law
(including, without limitation, the Delaware General Corporation Law) and as expressly provided in this Note. 
 12. [INSERT IN INITIAL NOTE
ONLY: NOTE REDUCTIONS. 
 (a) Filing Date Reduction. As of the date of filing of the Initial Registration Statement (as such

Late Charges with respect to such portion of such Principal and such Interest) shall be automatically extinguished and shall no longer remain outstanding hereunder without any payment thereof by the Company.

the ordinary course of business and (iii) a Fundamental Transaction in which all of the requirements set forth in Section 5(a) below have been met.

 17. REISSUANCE OF THIS NOTE. 

(a) Transfer. If this Note is to be transferred, the Holder shall surrender this Note to the Company, whereupon the Company will
forthwith issue and deliver upon the order of the Holder a new Note (in accordance with Section 17(d)), registered as the Holder may request, representing the outstanding Principal being transferred by the Holder and, if less than the entire
outstanding Principal is being transferred, a new Note (in accordance with Section 17(d)) to the Holder representing the outstanding Principal not being transferred. The Holder and any assignee, by acceptance of this Note, acknowledge and agree
that, by reason of the provisions of Section 3(c)(iii) following conversion or redemption of any portion of this Note, the outstanding Principal represented by this Note may be less than the Principal stated on the face of this Note. 

(b) Lost, Stolen or Mutilated Note. Upon receipt by the Company of evidence reasonably satisfactory to the Company of the loss, theft,
destruction or mutilation of this Note (as to which a written certification and the indemnification contemplated below shall suffice as such evidence), and, in the case of loss, theft or destruction, of any indemnification undertaking by the Holder
to the Company in customary and reasonable form and, in the case of mutilation, upon surrender and cancellation of this Note, the Company shall execute and deliver to the Holder a new Note (in accordance with Section 17(d)) representing the
outstanding Principal. 
 (c) Note Exchangeable for Different Denominations. This Note is exchangeable, upon the surrender hereof by
the Holder at the principal office of the Company, for a new Note or Notes (in accordance with Section 17(d) and in principal amounts of at least $1,000) representing in the aggregate the outstanding Principal of this Note, and each such new
Note will represent such portion of such outstanding Principal as is designated by the Holder at the time of such surrender. 
 (d)
Issuance of New Notes. Whenever the Company is required to issue a new Note pursuant to the terms of this Note, such new Note (i) shall be of like tenor with this Note, (ii) shall represent, as indicated on the face of such new
Note, the Principal remaining outstanding (or in the case of a new Note being issued pursuant to Section 17(a) or Section 17(c), the Principal designated by the Holder which, when added to the principal represented by the other new Notes
issued in connection with such issuance, does not exceed the Principal remaining outstanding under this Note immediately prior to such issuance of new Notes), (iii) shall have an issuance date, as indicated on the face of such new Note, which
is the same as the Issuance Date of this Note, (iv) shall have an exchange date, as indicated on the face of such new Note, which is the same as the Exchange Date of this Note, (v) shall have the same rights and conditions as this Note,
and (v) shall represent accrued and unpaid Interest and Late Charges on the Principal and Interest of this Note, from the Issuance Date. 

18. 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 and any of the other Transaction Documents at law or in equity (including a decree of specific performance and/or other injunctive relief), and nothing herein shall limit the
Holder’s right to pursue actual and consequential 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. Amounts set forth or provided for herein 

  
 20 







 
with respect to payments, conversion and the like (and the computation thereof) shall be the amounts to be received by the Holder and shall not, except as expressly provided herein, be subject to
any other obligation of the Company (or the performance thereof). 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 such breach or any such threatened breach, without
the necessity of showing economic loss and without any bond or other security being required. The Company shall provide all information and documentation to the Holder that is requested by the Holder to enable the Holder to confirm the
Company’s compliance with the terms and conditions of this Note. 
 19. 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 the Holder otherwise takes action to collect amounts due under this Note or to enforce the provisions
of this Note or (b) there occurs 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 or in connection with such bankruptcy, reorganization, receivership or other proceeding, including, without limitation, attorneys’ fees and disbursements. The Company expressly acknowledges
and agrees that no amounts due under this Note shall be affected, or limited, by the fact that the purchase price paid for this Note was less than the original Principal amount hereof. 

20. CONSTRUCTION; HEADINGS. This Note shall be deemed to be jointly drafted by the Company and the Holder and shall not be construed
against any Person as the drafter hereof. The headings of this Note are for convenience of reference and shall not form part of, or affect the interpretation of, this Note. Terms used in this Note but defined in the other Transaction Documents shall
have the meanings ascribed to such terms on the Initial Closing Date in such other Transaction Documents unless otherwise consented to in writing by the Holder. 

21. 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. No waiver shall be effective unless it
is in writing and signed by an authorized representative of the waiving party. 
 22. DISPUTE RESOLUTION. In the case of a dispute as
to the determination of the Conversion Price (including, without limitation, any disputed adjustment thereto), the Company Conversion Price, any Redemption Price, the Closing Bid Price, the Closing Sale Price, the Bid Price or fair market value (as
the case may be) or the arithmetic calculation of the Conversion Rate, any Note Reduction or the applicable Redemption Price (as the case may be), the Company or the Holder (as the case may be) shall submit the disputed determinations or arithmetic
calculations (as the case may be) via facsimile (i) within two (2) Business Days after receipt of the applicable notice giving rise to such dispute to the Company or the Holder (as the case may be) or (ii) if no notice gave rise to
such dispute, at any time after the Holder learned of the 

  
 21 







 
circumstances giving rise to such dispute. If the Holder and the Company are unable to agree upon such determination or calculation within two (2) Business Days of such disputed
determination or arithmetic calculation (as the case may be) being submitted to the Company or the Holder (as the case may be), then the Company shall, within two (2) Business Days, submit via facsimile (a) the disputed determination of
the Conversion Price, the Company Conversion Price, any Redemption Price, the Closing Bid Price, the Closing Sale Price, the Bid Price or fair market value (as the case may be) to an independent, reputable investment bank selected by the Company and
approved by the Holder or (b) the disputed arithmetic calculation of the Conversion Rate, any Note Reduction or any Redemption Price (as the case may be) to an independent, outside accountant selected by the Holder that is reasonably acceptable
to the Company. The investment bank or the accountant (as the case may be) to perform the determinations or calculations (as the case may be) and notify the Company and the Holder of the results no later than ten (10) Business Days from the
time it receives such disputed determinations or calculations (as the case may be). Such investment bank’s or accountant’s determination or calculation (as the case may be) shall be binding upon all parties absent demonstrable error. The
party that initiates the dispute (the “Initiating Party”) as to the determination of the Conversion Price (including, without limitation, any disputed adjustment thereto), the Company Conversion Price, any Redemption Price,
