 SECTION 4.
Registered Exchange Offer.  
 (a) Unless the Exchange Offer shall not be permissible under applicable law or Commission policy (after
the procedures set forth in Section 7(a) hereof have been complied with), the Company shall (i) cause to be filed with the Commission the Exchange Offer Registration Statement under the Securities Act relating to the Exchange Notes and the
Exchange Offer, (ii) use its commercially reasonable efforts to cause such Exchange Offer Registration Statement to become effective at the earliest practicable time, but in no event later than 240 days after the Closing Date (or if such 240th
day is not a Business Day, the next succeeding Business Day) (the “Exchange Offer Effectiveness Target Date”), (iii) in connection with the foregoing, file (A) all pre-effective amendments to
such Exchange Offer Registration Statement as may be necessary in order to cause such Exchange Offer Registration Statement to become effective, (B) if applicable, a post-effective amendment to such Exchange Offer Registration Statement
pursuant to Rule 430A under the Securities Act and (C), subject to the proviso in Section 7(c)(x), cause all necessary filings in connection with the registration and qualification of the Exchange Notes to be made under the state securities or
blue sky laws of such jurisdictions as are necessary to permit Consummation of the Exchange Offer, (iv) upon the effectiveness of such Exchange Offer Registration Statement, commence the Exchange Offer and (v) issue Exchange Notes in
exchange for all Initial Notes tendered prior to the Consummation of the Exchange Offer. The Exchange Offer Registration Statement shall be on the appropriate form permitting registration of the Exchange Notes to be offered in exchange for the
Entitled Securities and to permit resales of Initial Notes held by Broker-Dealers as contemplated by Section 4(c) hereof. Notwithstanding any other provision hereof, the Company shall not be obligated to file a Prospectus with the securities
commissions or similar regulatory authority in any of the provinces or territories of Canada. 
 (b) The Company shall use its commercially
reasonable efforts to cause the Exchange Offer Registration Statement to be effective continuously and shall keep the Exchange Offer open for a period of not less than the minimum period required under applicable federal and state securities laws to
Consummate the Exchange Offer; provided, however, that in no event shall such period be less than 20 Business Days from and including the date notice of the Exchange Offer is mailed to the Holders. The Company shall cause the Exchange Offer
to comply in all material respects with all applicable federal and state securities laws. No securities other than the Exchange Notes shall be included in the Exchange Offer Registration Statement. The Company shall use its commercially reasonable
efforts to cause the Exchange Offer to be Consummated within 30 Business Days (or longer if required by applicable securities laws) of the Exchange Offer Effectiveness Target Date. 

  
 4 

 (c) The Company shall indicate in a “Plan of Distribution” section contained in
the Prospectus forming a part of the Exchange Offer Registration Statement that any Broker-Dealer which holds Initial Notes that are Entitled Securities and that were acquired for its own account as a result of market-making activities or other
trading activities (other than Entitled Securities acquired directly from the Company), may exchange such Initial Notes pursuant to the Exchange Offer; however, such Broker-Dealer may be deemed to be an “underwriter” within the meaning of
the Securities Act and must, therefore, deliver a prospectus meeting the requirements of the Securities Act in connection with any resales of the Exchange Notes received by such Broker-Dealer in the Exchange Offer, which prospectus delivery
requirement may be satisfied by the delivery by such Broker-Dealer of the Prospectus contained in the Exchange Offer Registration Statement. Such “Plan of Distribution” section shall also contain all other information with respect to such
resales by Broker-Dealers that the Commission may require in order to permit such resales pursuant thereto, but such “Plan of Distribution” shall not name any such Broker-Dealer or disclose the amount of Initial Notes held by any such
Broker-Dealer except to the extent required by the Commission as a result of a change in policy after the date of this Agreement. 
 The
Company shall use its commercially reasonable efforts to keep the Exchange Offer Registration Statement continuously effective, supplemented and amended as required by the provisions of Section 7(c) hereof to the extent necessary to ensure that
it is available for resales of Initial Notes acquired by Broker-Dealers for their own accounts as a result of market-making activities or other trading activities, and to ensure that it conforms with the requirements of this Agreement, the
Securities Act and the policies, rules and regulations of the Commission as announced from time to time, for a period ending on the earlier of (i) 90 days from the date on which the Exchange Offer Registration Statement is declared effective and
(ii) the date on which a Broker-Dealer is no longer required to deliver a prospectus in connection with market-making or other trading activities. 

The Company shall provide sufficient copies of the latest version of such Prospectus to Broker-Dealers promptly upon request at any time
during such 90-day (or shorter as provided in the preceding paragraph) period in order to facilitate such resales. 

SECTION 5. Shelf Registration.  

(a) Shelf Registration. If (i) the Company is not permitted to file an Exchange Offer Registration Statement or to Consummate the
Exchange Offer because the Exchange Offer is not permitted by applicable law or Commission policy (after the procedures set forth in Section 7(a) hereof have been complied with), (ii) for any reason, the Exchange Offer is not Consummated within
30 Business Days of the Exchange Offer Effectiveness Target Date, or (iii) any Holder of Entitled Securities notifies the Company in writing that (A) such Holder is prohibited by applicable law or Commission policy from participating in
the Exchange Offer, or (B) such Holder may not resell the Exchange Notes acquired by it in the Exchange Offer to the public without delivering a prospectus and the Prospectus contained in the Exchange Offer Registration Statement is not
appropriate or available for such resales by such Holder, or (C) such Holder is a Broker-Dealer and holds Initial Notes acquired directly from the Company or one of its affiliates, then, upon such Holder’s written request, the Company
shall: 

  
 5 

 (i) cause to be filed a shelf registration statement pursuant to Rule 415
under the Securities Act, which may be an amendment to the Exchange Offer Registration Statement (in either event, the “Shelf Registration Statement”), which Shelf Registration Statement shall provide for resales of all Entitled Securities
the Holders of which shall have provided the information required pursuant to Section 5(b) hereof; and 
 (ii) use its
commercially reasonable efforts to cause such Shelf Registration Statement to be declared effective by the Commission on or before the 240th day after so requested or required pursuant to this Section 5 and to keep it continuously effective
until the earliest of (i) the date on which all Entitled Securities entitled to the benefit of this Section 5(a) have been sold pursuant to the Shelf Registration Statement, (ii) the date on which all Entitled Securities are no longer
“restricted securities” within the meaning of Rule 144 of the Securities Act and (iii) the date which is one year after the Closing Date, such shortest time period referred to as the “Effectiveness Period.” 

During the Effectiveness Period, the Company shall use its commercially reasonable efforts to keep such Shelf Registration Statement
continuously effective, supplemented and amended as required by the provisions of Sections 7(b) and (c) hereof to the extent necessary to ensure that it is available for resales of Initial Notes by the Holders of Entitled Securities entitled to
the benefit of this Section 5(a), and to ensure that it conforms in all material respects with the requirements of this Agreement, the Securities Act and the policies, rules and regulations of the Commission as announced from time to time. 

Notwithstanding the foregoing and any other provision hereof, the Company may suspend the availability of the Shelf Registration Statement,
without being required to pay any Additional Interest (as defined below), upon written notice to the Holders (which notice shall be accompanied by an instruction to suspend the use of the Prospectus), for one or more periods not to exceed 60
consecutive days in any 90-day period, and not to exceed, in the aggregate, 95 days in any 365-day period (each such period, a “Suspension Period”) if: 

(i) an event occurs and is continuing that, in the Company’s good faith judgment, would require the Company to make
changes in the Shelf Registration Statement or the Prospectus in order that the Shelf Registration Statement or the Prospectus does not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or
necessary to make the statements therein (in the case of the prospectus, in light of the circumstances under which they were made) not misleading; and 

(ii) the Company reasonably determines that the disclosure of such event at such time would have a material adverse effect on
the business of the Company (and its subsidiaries, if any, taken as a whole). 

  
 6 

 (b) Provision by Holders of Certain Information in Connection with the Shelf Registration
Statement. No Holder of Entitled Securities may include any of its Entitled Securities in any Shelf Registration Statement pursuant to this Agreement unless and until such Holder furnishes to the Company in writing, within 7 Business Days after
receipt of a request therefor, such information as the Company may reasonably request for use in connection with any Shelf Registration Statement or Prospectus or preliminary Prospectus included therein. Each Holder as to which any Shelf
Registration Statement is being effected agrees to furnish promptly to the Company all information required to be disclosed in order to make the information previously furnished to the Company by such Holder not materially misleading. 

SECTION 6. Additional Interest. If (i) the Company fails to file any of the Registration Statements required
by this Agreement on or before the date specified for such filing, if any; (ii) any of the Registration Statements required by this Agreement has not been declared effective by the Commission on or prior to the date specified for such
effectiveness in this Agreement (the “Effectiveness Target Date”), (iii) the Exchange Offer has not been Consummated within 30 Business Days of the Exchange Offer Effectiveness Target Date or (iv) any Registration Statement required
by this Agreement is filed and declared effective but shall thereafter cease to be effective (other than for a Suspension Period) without being succeeded within five Business Days by a post-effective amendment to such Registration Statement that is
declared effective (each such event referred to in clauses (i) through (iv), a “Registration Default”), the Company hereby agrees that the interest rate borne by the Entitled Securities shall be increased by 0.25% per annum during the
90-day period immediately following the occurrence of any Registration Default and shall increase by 0.25% per annum at the beginning of each subsequent 90-day period
(such increase, “Additional Interest”) until all Registration Defaults have been cured, but in no event shall such increase exceed 1.00% per annum. Following the cure of all Registration Defaults relating to any particular Entitled
Securities, the interest rate borne by the relevant Entitled Securities will be reduced to the original interest rate borne by such Entitled Securities; provided, however, that, if after any such reduction in interest rate, a different
Registration Default occurs, the interest rate borne by the relevant Entitled Securities shall again be increased pursuant to the foregoing provisions. The Company shall not be required to pay Additional Interest for more than one Registration
Default at a time. The amount of Additional Interest will be determined on the basis of a 360-day year comprised of twelve 30-day months and the actual number of days on
which Additional Interest accrued during such period. 
 In connection with a Registration Default in respect of a Shelf Registration
Statement, notwithstanding anything to the contrary herein, a Holder will not be entitled to any Additional Interest under this Article 6 if such Holder has not provided all registration information to the Company as required herein at least two
Business Days prior to the Effective Date of the Shelf Registration Statement or any subsequent amendment (with respect to any period subsequent to such amendment and prior to the next amendment in respect of which such information is so provided).

 All obligations of the Company set forth in the preceding paragraph to pay Additional Interest that are outstanding with respect to any
Entitled Security at the time such security ceases to be an Entitled Security shall survive until such time as all such obligations with respect to such security shall have been satisfied in full.

 SECTION 7. Registration Procedures.  

(a) Exchange Offer Registration Statement. In connection with the Exchange Offer, the Company shall comply with all of the provisions of
Section 7(c) hereof, shall use its commercially reasonable efforts to effect such exchange so that it permits the sale of Entitled Securities being sold in accordance with the intended method or methods of distribution thereof, and shall comply
with all of the following provisions: 
 (i) As a condition to its participation in the Exchange Offer pursuant to the terms
of this Agreement, each Holder of Entitled Securities shall furnish, upon the request of the Company, prior to the Consummation thereof, a written representation to the Company (which may be contained in the letter of transmittal contemplated by the
Exchange Offer Registration Statement) to the effect that (A) it is not an affiliate of the Company (within the meaning of Rule 405 of the Securities Act), (B) it is not engaged in, and does not intend to engage in, and has no arrangement or
understanding with any Person to participate in, a distribution of the Exchange Notes to be issued in the Exchange Offer and (C) it is acquiring the Exchange Notes in its ordinary course of business. In addition, all such Holders of Entitled
Securities shall otherwise cooperate in the Company’s preparations for the Exchange Offer, including providing all information relating to the Holder required to be included in a Registration Statement under applicable law. Each Holder hereby
acknowledges and agrees that any Broker-Dealer and any such Holder using the Exchange Offer to participate in a distribution of the securities to be acquired in the Exchange Offer (1) could not under Commission policy as in effect on the date
of this Agreement rely on the position of the Commission enunciated in Morgan Stanley and Co., Inc. (available June 5, 1991) and Exxon Capital Holdings Corporation (available May 13, 1988), as interpreted in the
Commission’s letter to Shearman & Sterling dated July 2, 1993, and similar no-action letters (which may include any no-action letter obtained pursuant
to clause (i) above), and (2) must comply with the registration and prospectus delivery requirements of the Securities Act in connection with a secondary resale transaction and that such a secondary resale transaction should be covered by
an effective registration statement containing the selling security holder information required by Item 507 or 508, as applicable, of Regulation S-K if the resales are of Exchange Notes obtained by such Holder
in exchange for Initial Notes acquired by such Holder directly from the Company. 
 (b) Shelf Registration Statement. In connection
with the Shelf Registration Statement, the Company shall comply with all the provisions of Section 7(c) hereof and shall use its commercially reasonable efforts to effect such registration so that it permits the sale of the Entitled Securities
being sold in accordance with the intended method or methods of distribution thereof. 
 (c) General Provisions. In connection with
any Registration Statement and any Prospectus required by this Agreement to permit the sale or resale of Entitled Securities (including, without limitation, any Registration Statement and the related Prospectus required to permit resales of Initial
Notes by Broker-Dealers), the Company shall: 

  
 8 

 (i) subject to the terms hereof, use its commercially reasonable efforts to
keep such Registration Statement continuously effective and provide all requisite financial statements (including, if required by the Securities Act or any regulation thereunder, its financial statements for the period specified in Section 4 or
5 hereof, as applicable); upon the occurrence of any event that would cause any such Registration Statement or the Prospectus contained therein (A) to contain a material misstatement or omission or (B) not to be effective and usable for
resale of Entitled Securities during the period required by this Agreement, the Company shall file promptly an appropriate amendment to such Registration Statement, in the case of clause (A), correcting any such misstatement or omission, and, in the
case of either clause (A) or (B), use its commercially reasonable efforts to cause such amendment to be declared effective and such Registration Statement and the related Prospectus to become usable for their intended purpose(s) as soon as
practicable thereafter; 
 (ii) prepare and file with the Commission such amendments and post-effective amendments to the
applicable Registration Statement as may be necessary to keep the Registration Statement effective for the applicable period set forth in Section 4 or 5 hereof, as applicable, or such shorter period as will terminate when all Entitled
Securities covered by such Registration Statement have been sold or cease to be Entitled Securities; cause the Prospectus to be supplemented by any required Prospectus supplement, and as so supplemented to be filed pursuant to Rule 424 under the
Securities Act, and to comply fully with the applicable provisions of Rules 424, 430A and 430B under the Securities Act in a timely manner; and comply with the provisions of the Securities Act with respect to the disposition of all securities
covered by such Registration Statement during the applicable period in accordance with the intended method or methods of distribution by the sellers thereof set forth in such Registration Statement or supplement to the Prospectus; 

(iii) advise the underwriter(s), if any, and selling Holders within five Business Days and, if requested by such Persons, to
confirm such advice in writing, (A) when the Prospectus or any Prospectus supplement or post-effective amendment has been filed, and, with respect to any Registration Statement or any post-effective amendment thereto, when the same has become
effective, (B) of any request by the Commission for amendments to the Registration Statement or amendments or supplements to the Prospectus or for additional information relating thereto, (C) of the issuance by the Commission of any stop
order suspending the effectiveness of the Registration Statement under the Securities Act or of the suspension by any state securities commission of the qualification of the Entitled Securities for offering or sale in any jurisdiction, or the
initiation of any proceeding for any of the preceding purposes, (D) of the existence of any fact or the happening of any event that makes any statement of a material fact made in the Registration Statement, the Prospectus, any amendment or
supplement thereto, or any document incorporated by reference therein untrue, or that requires the making of any additions to or changes in the Registration Statement or the Prospectus in order to make the statements therein not misleading. If at
any time the Commission shall issue any stop order suspending the effectiveness of the Registration Statement, or any state securities commission or other regulatory authority shall issue an order suspending the qualification or exemption from
qualification of the Entitled Securities under state securities or blue sky laws, the Company shall use its commercially reasonable efforts to obtain the withdrawal or lifting of such order at the earliest possible time; 

  
 9 

 (iv) upon written request, furnish without charge to each of the Initial
Purchasers, each selling Holder named in any Registration Statement, and each of the underwriter(s), if any, before filing with the Commission, copies of any Registration Statement or any Prospectus included therein or any amendments or supplements
to any such Registration Statement or Prospectus, which documents will be subject to the review and comment of such Holders and underwriter(s) in connection with such sale, if any, for a period of at least two Business Days, and the Company will not
file any such Registration Statement or Prospectus or any amendment or supplement to any such Registration Statement or Prospectus to which an Initial Purchaser of Entitled Securities covered by such Registration Statement or the underwriter(s), if
any, shall reasonably object in writing within two Business Days after the receipt thereof (such objection to be deemed timely made upon confirmation of telecopy transmission within such period) provided, that this clause
(iv) shall not apply to any filing by the Company of any annual report on Form 10-K, quarterly report on Form 10-Q or current report on Form 8-K with respect to matters unrelated to the Entitled Securities and the offering or exchange thereof; 

(v) in the case of an Underwritten Registration, make available during normal business hours for inspection by the Initial
Purchasers, the managing underwriter(s), if any, participating in any disposition pursuant to such Registration Statement and any attorney or accountant retained by such Initial Purchasers or any of the underwriter(s), all of its financial and other
records, pertinent corporate documents and properties and cause its officers, directors and employees to supply all information reasonably requested by any such Initial Purchaser, underwriter, attorney or accountant in connection with such
Registration Statement or any post-effective amendment thereto subsequent to the filing thereof and prior to its effectiveness and to participate in meetings with investors to the extent requested by the managing underwriter(s), if any; 

(vi) in the case of a Shelf Registration Statement, if requested by any selling Holders or the underwriter(s), if any, promptly
incorporate in any Registration Statement or Prospectus, pursuant to a supplement or post-effective amendment if necessary, such information as such selling Holders and underwriter(s), if any, may reasonably request to have included therein,
information relating to the “Plan of Distribution” of the Entitled Securities, information with respect to the principal amount of Entitled Securities being sold to such underwriter(s), the purchase price being paid therefor and any other
terms of the offering of the Entitled Securities to be sold in such offering; and make all required filings of such Prospectus supplement or post-effective amendment as soon as practicable after it is notified of the matters to be incorporated in
such Prospectus supplement or post-effective amendment; 
 (vii) upon request, furnish to each Initial Purchaser, each
selling Holder and each of the underwriter(s), if any, without charge, at least one copy of the Registration Statement, as first filed with the Commission, and of each amendment thereto, including financial statements and schedules, all documents
incorporated by reference therein and all exhibits (including exhibits incorporated therein by reference); 

  
 10 

 (viii) deliver to each selling Holder and each of the underwriter(s), if
any, who is required to deliver a Prospectus in connection with the sale of its Entitled Securities, without charge, as many copies of the Prospectus (including each preliminary prospectus) and any amendment or supplement thereto as such Persons
reasonably may request; the Company hereby consents to the use of the Prospectus and any amendment or supplement thereto by each of the selling Holders and each of the underwriter(s), if any, in connection with the offering and the sale of the
Entitled Securities covered by the Prospectus or any amendment or supplement thereto; 
 (ix) enter into such agreements
(including an underwriting agreement), and make such representations and warranties, and take all such other actions in connection therewith in order to expedite or facilitate the disposition of the Entitled Securities pursuant to any Shelf
Registration Statement contemplated by this Agreement, all to such extent as may reasonably be requested by any Initial Purchaser or by any Holder of Entitled Securities or underwriter and as are reasonably on terms customary for transactions of
such nature in connection with any sale or resale pursuant to any Registration Statement contemplated by this Agreement; and if an underwriting agreement is entered into and the registration is an Underwritten Registration, the Company shall: 

(A) furnish to each Initial Purchaser, each selling Holder and each underwriter, if any, in such substance and scope as they
may reasonably request and as are customarily made by issuers to underwriters in primary underwritten offerings, upon the date of the Consummation of the Exchange Offer or, if applicable, the effectiveness of the Shelf Registration Statement: 

(1) a certificate, dated the date of Consummation of the Exchange Offer or the date of effectiveness of the Shelf Registration
Statement, as the case may be, signed by (y) the President or any Vice President and (z) a principal financial or accounting officer of the Company, confirming, as of the date thereof, the matters set forth in paragraphs (i) and (ii)
of Section 5(d) of the Purchase Agreement and such other matters as such parties may reasonably request;

 (3) a customary comfort letter, dated the date of effectiveness of the Shelf
Registration Statement, from the Company’s independent accountants for the three fiscal years ended December 31, 2020 and all subsequent financial reporting periods, if permitted by applicable accounting standards or pronouncements, in the
customary form and covering matters of the type customarily requested to be covered in comfort letters by underwriters in connection with primary underwritten offerings, and covering or affirming the matters set forth in the comfort letters
delivered pursuant to Section 5(h) of the Purchase Agreement;

If at any time the representations and warranties contemplated in Section 7(c)(xi)(A)(1) hereof cease to be true and
correct, the Company shall so advise the Initial Purchasers and the underwriter(s), if any, and each selling Holder promptly and, if requested by such Persons, shall confirm such advice in writing; 

(x) prior to any public offering of Entitled Securities, cooperate with the selling Holders, the underwriter(s), if any, and

do any and all other acts or things necessary or advisable to enable the disposition in such jurisdictions of the Entitled Securities covered by the Shelf Registration Statement; provided, however, that the Company shall not be required to
register or qualify as a foreign corporation where it is not then so qualified or to take any action that would subject it to the service of process in suits or to taxation, in any jurisdiction where it is not then so subject; 

(xi) shall issue, upon the request of any Holder of Initial Notes covered by the Shelf Registration Statement, Exchange Notes

disposition of such Entitled Securities, subject to the proviso contained in Section 7(c)(xii) hereof; 
 (xiv) if any
fact or event contemplated by Section 7(c)(iii)(D) hereof shall exist or have occurred, prepare a supplement or post-effective amendment to the Registration Statement or related Prospectus or any document incorporated therein by reference or
file any other required document so that, as thereafter delivered to the purchasers of Entitled Securities, the Prospectus will not contain an untrue statement of a material fact or omit to state any material fact necessary in order to make the
statements therein not misleading; 
 (xv) provide a CUSIP number for all Exchange Notes not later than the effective date of
the Registration Statement covering such Exchange Notes and provide the Trustee under the Indenture with printed certificates for such Exchange Notes which are in a form eligible for deposit with the Depository Trust Company and take all other
action necessary to ensure that all such Securities are eligible for deposit with the Depository Trust Company; 
 (xvi)
cooperate and assist in any filings required to be made with the FINRA and in the performance of any due diligence investigation by any underwriter that is required to be retained in accordance with the rules and regulations of the FINRA; 

(xvii) otherwise use its commercially reasonable efforts to comply in all material respects with all applicable rules and
regulations of the Commission, and make generally available to its security holders, as soon as practicable, a consolidated earnings statement meeting the requirements of Rule 158 under the Securities Act (which need not be audited) for the
twelve-month period (A) commencing at the end of any fiscal quarter in which Entitled Securities are sold to underwriters in a firm commitment or best efforts Underwritten Offering or (B) if not sold to underwriters in such an offering,

 (xix) cause all Exchange
Notes covered by the Registration Statement to be listed on each securities exchange or automated quotation system on which similar securities issued by the Company are then listed if requested by the Holders of a majority in aggregate principal
amount of Initial Notes or the managing underwriter(s), if any; and 

  
 13 

 Each Holder agrees by acquisition of a Entitled Security that, upon receipt of any notice
from the Company of a Suspension Period or the existence of any fact of the kind described in Section 7(c)(iii)(D) hereof, such Holder will forthwith discontinue disposition of Entitled Securities pursuant to the applicable Registration
Statement until such Holder’s receipt of the copies of the supplemented or amended Prospectus contemplated by Section 7(c)(xvi) hereof, or until it is advised in writing (the “Advice”) by the Company that the use of the
Prospectus may be resumed, and has received copies of any additional or supplemental filings that are incorporated by reference in the Prospectus. If so directed by the Company, each Holder will deliver to the Company (at the Company’s expense)
all copies, other than permanent file copies then in such Holder’s possession, of the Prospectus covering such Entitled Securities that was current at the time of receipt of such notice. In the event the Company shall give any such notice, the
time period regarding the effectiveness of such Registration Statement set forth in Section 4 or 5 hereof, as applicable, shall be extended by the number of days during the period from and including the date of the giving of such notice
pursuant to Section 7(c)(iii)(D) hereof to and including the date when each selling Holder covered by such Registration Statement shall have received the copies of the supplemented or amended Prospectus contemplated by Section 7(c)(xvi)
hereof or shall have received the Advice; provided, however, that no such extension shall be taken into account, except in connection with a Suspension Period, in determining whether Additional Interest is due pursuant to Section 6
hereof or the amount of such Additional Interest, it being agreed that the Company’s option to suspend use of a Registration Statement pursuant to this paragraph shall be treated as a Registration Default for purposes of Section 6 hereof.

 SECTION 8. Registration Expenses.  

(a) All expenses incident to the Company’s performance of or compliance with this Agreement will be borne by the Company, regardless of
whether a Registration Statement becomes effective, including, without limitation: (i) all registration and filing fees and expenses (including filings made by any Initial Purchaser or Holder with the FINRA (and, if applicable, the fees and
expenses of any “qualified independent underwriter” and its counsel that may be required by the rules and regulations of the FINRA)); (ii) all fees and expenses of compliance with federal securities and state securities or blue sky laws;
(iii) all expenses of printing (including printing certificates for the Exchange Notes to be issued in the Exchange Offer and printing of Prospectuses), messenger and delivery services and telephone; (iv) all fees and disbursements of the
Company’s counsel and, subject to Section 8(b) hereof, the Holders of Entitled Securities; (v) all application and filing fees in connection with listing the Exchange Notes on a securities exchange or automated quotation system
pursuant to the requirements thereof; and (vi) all fees and disbursements of the Company’s independent certified public accountants (including the expenses of any special audit and comfort letters required by or incident to such
performance). 
 The Company will, in any event, bear its internal expenses (including, without limitation, all salaries and expenses of its
officers and employees performing legal or accounting duties), the expenses of any annual audit and the fees and expenses of any Person, including special experts, retained by it. 

  
 14 

 (b) In connection with any Registration Statement required by this Agreement (including,
without limitation, the Exchange Offer Registration Statement and the Shelf Registration Statement), the Company will reimburse the Initial Purchasers and the Holders of Entitled Securities being tendered in the Exchange Offer and/or resold pursuant
to the “Plan of Distribution” contained in the Exchange Offer Registration Statement or registered pursuant to the Shelf Registration Statement, as applicable, for the reasonable fees and disbursements of not more than one counsel, who
shall be such counsel as may be chosen by the Holders of a majority in principal amount of the Entitled Securities for whose benefit such Registration Statement is being prepared. 

SECTION 9. Indemnification.  

(a) The Company agrees to indemnify and hold harmless (i) each Holder and (ii) each Person, if any, who controls (within the meaning
of Section 15 of the Securities Act or Section 20 of the Exchange Act) any Holder (any of the Persons referred to in this clause (ii) being hereinafter referred to as a “controlling person”) and (iii) the respective
officers, directors, partners, employees, representatives and agents of any Holder or any controlling person (any Person referred to in clause (i), (ii) or (iii) may hereinafter be referred to as an “Indemnified Holder”), to the
fullest extent lawful, from and against any and all losses, claims, damages, liabilities and expenses (or actions in respect thereof) (including, without limitation, and as incurred, reimbursement of all reasonable costs of investigating, or
defending any claim or action, or any investigation or proceeding by any governmental agency or body, including the reasonable fees and expenses of counsel to any Indemnified Holder), joint or several, directly or indirectly caused by, related to,
based upon, arising out of or in connection with any untrue statement or alleged untrue statement of a material fact contained in any Registration Statement or Prospectus (or any amendment or supplement thereto), or any omission or alleged omission
to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as such losses, claims, damages, liabilities or expenses are caused by an untrue statement or omission or
alleged untrue statement or omission that is made in reliance upon and in conformity with information relating to any of the Holders furnished in writing to the Company by any of the Holders expressly for use therein. This indemnity agreement shall
be in addition to any liability which the Company may otherwise have. 
 In case any action or proceeding (including any governmental or
regulatory investigation or proceeding) shall be brought or asserted against any of the Indemnified Holders with respect to which indemnity may be sought against the Company, such Indemnified Holder (or the Indemnified Holder controlled by such
controlling person) shall promptly notify the Company in writing; provided, however, that the failure to give such notice shall not relieve any of the Company of its obligations pursuant to this Agreement. Such Indemnified Holder shall have
the right to employ its own counsel in any such action and the fees and expenses of such counsel shall be paid, as incurred, by the Company (regardless of whether it is ultimately determined that an Indemnified Holder is not entitled to
indemnification hereunder). Notwithstanding the foregoing, the Company shall not, in connection with any one such action or proceeding or separate but substantially similar or related actions or proceedings in the same jurisdiction arising out of
the same general allegations or circumstances, be liable for the reasonable fees and expenses of more than one separate firm of attorneys (in addition to any local counsel) at any time for such Indemnified Holders, which firm shall be designated by
the Holders. The 

  
 15 

 
Company shall be liable for any settlement of any such action or proceeding effected with the Company’s prior written consent, which consent shall not be withheld unreasonably, and the
Company agrees to indemnify and hold harmless any Indemnified Holder from and against any loss, claim, damage, liability or expense by reason of any settlement of any action effected with the Company’s written consent. The Company shall not,
without the prior written consent of each Indemnified Holder, settle or compromise or consent to the entry of judgment in or otherwise seek to terminate any pending or threatened action, claim, litigation or proceeding in respect of which
indemnification or contribution may be sought hereunder (whether or not any Indemnified Holder is a party thereto), unless such settlement, compromise, consent or termination includes an unconditional release of each Indemnified Holder from all
liability arising out of such action, claim, litigation or proceeding. 
 (b) Each Holder of Entitled Securities agrees, severally and not
jointly, to indemnify and hold harmless the Company and its directors and officers who sign a Registration Statement, and any Person controlling (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) the
Company and the officers, directors, partners, employees, representatives and agents of each such Person, to the same extent as the foregoing indemnity from the Company to each of the Indemnified Holders, but only with respect to claims and actions
based on information relating to such Holder furnished in writing by such Holder expressly for use in any Registration Statement or Prospectus. In case any action or proceeding shall be brought against the Company or its directors or officers or any
such controlling person in respect of which indemnity may be sought against a Holder of Entitled Securities, such Holder shall have the rights and duties given the Company, and the Company, its directors and officers and such controlling Person
shall have the rights and duties given to each Holder, in each case, by the preceding paragraph. 
 (c) If the indemnification provided for
in this Section 9 is unavailable to an indemnified party under Section 9(a) or (b) hereof (other than by reason of exceptions provided in those Sections) in respect of any losses, claims, damages, liabilities, judgments, actions or
expenses referred to therein, then each applicable indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages, liabilities
or expenses in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand, and the Holders, on the other hand, from the Initial Placement (which in the case of the Company shall be deemed to be equal
to its total gross proceeds from the Initial Placement), the amount of Additional Interest which did not become payable as a result of the filing of the Registration Statement resulting in such losses, claims, damages, liabilities, judgments actions
or expenses, and such Registration Statement, or if such allocation is not permitted by applicable law, the relative fault of the Company, on the one hand, and the Holders, on the other hand, in connection with the statements or omissions which
resulted in such losses, claims, damages, liabilities or expenses, as well as any other relevant equitable considerations. The relative fault of the Company, on the one hand, and of the Indemnified Holder, on the other hand, shall be determined by
reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company, on the one hand, or the Indemnified
Holders, on the other hand, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The amount paid or payable by a party as a result of the losses, claims, damages,
liabilities and expenses referred to above shall be deemed to include, subject to the limitations set forth in the second paragraph of Section 9(a) hereof, any legal or other fees or expenses reasonably incurred by such party in connection with
investigating or defending any action or claim. 

  
 16 

 Each of the Company and the Holders of Entitled Securities agrees that it would not be just
and equitable if contribution pursuant to this Section 9(c) were determined by pro rata allocation (even if the Holders were treated as one entity for such purpose) or by any other method of allocation which does not take account of the
equitable considerations referred to in the immediately preceding paragraph. The amount paid or payable by an indemnified party as a result of the losses, claims, damages, liabilities or expenses referred to in the immediately preceding paragraph
shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions
of this Section 9, none of the Holders (and its related Indemnified Holders) shall be required to contribute, in the aggregate, any amount in excess of the amount by which the total discount received by such Holder with respect to the Initial
Notes exceeds the amount of any damages which such Holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No Person guilty of fraudulent misrepresentation (within the meaning
of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. The Holders’ obligations to contribute pursuant to this Section 9(c) are several in
proportion to the respective principal amount of Initial Notes held by each of the Holders hereunder and not joint. 

SECTION 10. Rule 144A. The Company hereby agrees with each Holder, for so long as any Entitled Securities remain
outstanding, to make available to any Holder or beneficial owner of Entitled Securities in connection with any sale thereof and any prospective purchaser of such Entitled Securities from such Holder or beneficial owner, the information required by
Rule 144A(d)(4) under the Securities Act in order to permit resales of such Entitled Securities pursuant to Rule 144A under the Securities Act. 

SECTION 11. Participation in Underwritten Registrations. No Holder may participate in any Underwritten Registration
hereunder unless such Holder (a) agrees to sell such Holder’s Entitled Securities on the basis provided in any underwriting arrangements approved by the Persons entitled hereunder to approve such arrangements and (b) completes and
executes all reasonable questionnaires, powers of attorney, indemnities, underwriting agreements, lock-up letters and other documents required under the terms of such underwriting arrangements. 

SECTION 12. Selection of Underwriters. The Holders of Entitled Securities covered by the Shelf Registration
Statement who desire to do so may sell such Entitled Securities in an Underwritten Offering. In any such Underwritten Offering, the investment banker(s) and managing underwriter(s) that will administer such offering will be selected by the Holders
of a majority in aggregate principal amount of the Entitled Securities included in such offering; provided, however, that such investment banker(s) and managing underwriter(s) must be reasonably satisfactory to the Company; provided
further, that if the Company is conducting a primary issuance of securities in such Underwritten Offering, the Company shall have sole discretion in such selection. 

  
 17 

 SECTION 13. Miscellaneous.  

(a) Remedies. The Company hereby agrees that monetary damages would not be adequate compensation for any loss incurred by reason of a
breach by it of the provisions of this Agreement and hereby agree to waive the defense in any action for specific performance that a remedy at law would be adequate. 

(b) No Inconsistent Agreements. The Company will not, on or after the date of this Agreement, enter into any agreement with respect to
its securities that is inconsistent with the rights granted to the Holders in this Agreement or otherwise conflicts with the provisions hereof. The Company has not previously entered into any agreement granting any registration rights with respect
to its securities to any Person. The rights granted to the Holders hereunder do not in any way conflict with and are not inconsistent with the rights granted to the holders of the Company’s securities under any agreement in effect on the date
hereof. 
 (c) Amendments and Waivers. The provisions of this Agreement may not be amended, modified or supplemented, and waivers or
consents to or departures from the provisions hereof may not be given unless the Company has (i) in the case of Section 6 hereof and this Section 13(c)(i), obtained the written consent of Holders of all outstanding Entitled Securities
and (ii) in the case of all other provisions hereof, obtained the written consent of Holders of a majority of the outstanding principal amount of Entitled Securities (excluding any Entitled Securities held by the Company or its Affiliates).
Notwithstanding the foregoing, a waiver or consent to departure from the provisions hereof that relates exclusively to the rights of Holders whose securities are being tendered pursuant to the Exchange Offer and that does not affect directly or
indirectly the rights of other Holders whose securities are not being tendered pursuant to such Exchange Offer may be given by the Holders of a majority of the outstanding principal amount of Entitled Securities being tendered or registered;
provided, however, that, with respect to any matter that directly or indirectly affects the rights of any Initial Purchaser hereunder, the Company shall obtain the written consent of such Initial Purchaser with respect to which such
amendment, qualification, supplement, waiver, consent or departure is to be effective. 
 (d) Notices. All notices and other
communications provided for or permitted hereunder shall be made in writing by hand-delivery, first-class mail (registered or certified, return receipt requested), telex, facsimile, or air courier guaranteeing overnight delivery: 

(i) if to a Holder, at the address set forth on the records of the Registrar under the Indenture, with a copy to the Registrar

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

the value of such fractional share in cash. The Company shall pay any and all transfer, stamp, issuance and similar taxes, costs
and expenses (including, without limitation, fees and expenses of the Transfer Agent (as defined below)) that may be payable with

be determined by dividing (x) such Conversion Amount by (y) the Conversion Price (the “Conversion Rate”).

determination is being made and (y) 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, if any.

 

(ii) “Conversion
Price” means, as of any Conversion Date or other date of determination, $4.00, subject to adjustment as provided herein.

 

(c) Mechanics

(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, electronic mail 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), within two (2) Trading Days following a conversion of this
Note as aforesaid, 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 18(b)). On or before the first (1st) Trading Day following the date of receipt of a Conversion Notice, the
Company shall transmit by facsimile or electronic mail an acknowledgment of confirmation and representation as to whether such
shares of Common Stock may then be resold pursuant to Rule 144 or an effective and available registration statement, 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”) which confirmation shall constitute an instruction to the Transfer Agent to process such
Conversion Notice in accordance with the terms herein. On or before the second (2nd) Trading Day following the date
on which the Company has received a Conversion Notice (or such earlier date as required pursuant to the 1934 Act or other applicable
law, rule or regulation for the settlement of a trade initiated on the applicable Conversion Date of such shares of Common Stock
issuable pursuant to such Conversion Notice) (the “Share Delivery Deadline”), the Company shall (1) provided
that the Transfer Agent is participating in The Depository Trust Company’s (“DTC”) Fast Automated Securities
Transfer Program, credit such aggregate number of shares of Common Stock to which the Holder shall be entitled pursuant to such
conversion 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, upon the request of the
Holder, 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
pursuant to such conversion. If this Note is physically surrendered for conversion pursuant to 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 two (2) Business 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 18(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. In the event of
a partial conversion of this Note pursuant hereto, the Principal amount converted shall be deducted from the Installment Amount(s)
relating to the Installment Date(s) as set forth in the applicable Conversion Notice. Notwithstanding anything to the contrary
contained in this Note or the Registration Rights Agreement, after the effective date of the Registration Statement (as defined
in the Registration Rights Agreement) and prior to the Holder’s receipt of the notice of a Grace Period (as defined in the
Registration Rights Agreement), the Company shall cause the Transfer Agent to deliver unlegended shares of Common Stock to the
Holder (or its designee) in connection with any sale of Registrable Securities (as defined in the Registration Rights Agreement)
with respect to which the Holder has entered into a contract for sale, and delivered a copy of the prospectus included as part
of the particular Registration Statement to the extent applicable, and for which the Holder has not yet settled.

(ii) Company’s
Failure to Timely Convert. If the Company shall fail, for any reason or for no reason, on or prior to the applicable Share
Delivery Deadline, either (I) if the Transfer Agent is not participating in the DTC Fast Automated Securities Transfer Program,
to issue and deliver to the Holder (or its designee) 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, if the Transfer Agent is participating
in the DTC Fast Automated Securities Transfer Program, to credit the balance account of the Holder or the Holder’s designee
with DTC for such number of shares of Common Stock to which the Holder is entitled upon the Holder’s conversion of this Note
(as the case may be) or (II) if the Registration Statement covering the resale of the shares of Common Stock that are the subject
of the Conversion Notice (the “Unavailable Conversion Shares”) is not available for the resale of such Unavailable
Conversion Shares and the Company fails to promptly, but in no event later than as required pursuant to the Registration Rights
Agreement (x) so notify the Holder and (y) deliver the shares of Common Stock electronically without any restrictive legend by
crediting such aggregate number of shares of Common Stock to which the Holder is entitled pursuant to such conversion to the Holder’s
or its designee’s balance account with DTC through its Deposit/Withdrawal At Custodian system (the event described in the
immediately foregoing clause (II) is hereinafter referred as a “Notice Failure” and together with the event
described in clause (I) above, 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 or prior to the Share Delivery Deadline and to which the Holder is entitled, multiplied
by (B) any trading price of the Common Stock selected by the Holder in writing as in effect at any time during the period beginning
on the applicable Conversion Date and ending on the applicable Share Delivery Deadline 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 either (A) if the
Transfer Agent is not participating in the DTC Fast Automated Securities Transfer Program, the Company shall fail to issue and
deliver to the Holder (or its designee) a certificate and register such shares of Common Stock on the Company’s share register
or, if the Transfer Agent is participating in the DTC Fast Automated Securities Transfer Program, the Transfer Agent shall fail
to credit the balance account of the Holder or the Holder’s designee with DTC for the number of shares of Common Stock to
which the Holder is entitled upon the Holder’s conversion hereunder or pursuant to the Company’s obligation pursuant
to clause (II) below or (B) a Notice Failure occurs, and if on or after such Share Delivery Deadline the Holder purchases (in an
open market transaction or otherwise) shares of Common Stock corresponding to all or any portion of the number of shares of Common
Stock issuable upon such conversion that the Holder is entitled to receive from the Company and has not received from the Company
in connection with such Conversion Failure or Notice Failure, as applicable (a “Buy-In”), then, in addition
to all other remedies available to the Holder, the Company shall, within two (2) 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 (and to issue such shares of Common Stock)
or credit the balance account of such Holder or such Holder’s designee, as applicable, 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 balance account of such Holder or such Holder’s designee,
as applicable, 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) (the “Buy-In Payment Amount”). Nothing shall limit the Holder’s right
to pursue any other 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 shares
of Common Stock (or to electronically deliver such shares of Common Stock) upon the conversion of this Note as required pursuant
to the terms hereof.

 

    4

     

    

 

(iii) Registration;
Book-Entry. The Company shall maintain a register (the “Register”) for the recordation of the names and
addresses of the holders of each Note and the principal amount of the Notes held by such holders (the “Registered Notes”).
The entries in the Register shall be conclusive and binding for all purposes absent manifest error. The Company and the holders
of the Notes shall treat each Person whose name is recorded in the Register as the owner of a Note for all purposes (including,
without limitation, the right to receive payments of Principal and Interest hereunder) notwithstanding notice to the contrary.
A Registered Note may be assigned, transferred or sold in whole or in part only by registration of such assignment or sale on the
Register. Upon its receipt of a written request to assign, transfer or sell all or part of any Registered Note by the holder thereof,
the Company shall record the information contained therein in the Register and issue one or more new Registered Notes in the same
aggregate principal amount as the principal amount of the surrendered Registered Note to the designated assignee or transferee
pursuant to Section 18, provided that if the Company does not so record an assignment, transfer or sale (as the case may be)
of all or part of any Registered Note within two (2) Business Days of such a request, then the Register shall be automatically
deemed updated to reflect such assignment, transfer or sale (as the case may be). 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 (as the case may be) and the dates of such conversions and/or
payments (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. If the Company does not update the Register to record such Principal,
Interest and Late Charges converted and/or paid (as the case may be) and the dates of such conversions and/or payments (as the
case may be) within two (2) Business Days of such occurrence, then the Register shall be automatically deemed updated to reflect
such occurrence.

 

(iv) Pro
Rata Conversion; Disputes. In the event that the Company receives a Conversion Notice from more than one holder of Notes for
the same Conversion Date and the Company can convert some, but not all, of such portions of the Notes submitted for conversion,
the Company, subject to Section 3(d), shall convert from each holder of Notes electing to have Notes converted on such date a pro
rata amount of such holder’s portion of its Notes submitted for conversion based on the principal amount of Notes submitted
for conversion on such date by such holder relative to the aggregate principal amount of all Notes submitted for conversion on
such date. 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 23.

 

    5

     

    

 

(d) Limitations
on Conversions.

 

(i) Beneficial
Ownership. The Company shall not effect the conversion of any portion of this Note, and the Holder shall not have the right
to convert any portion of this Note pursuant to the terms and conditions of this Note and any such conversion shall be null and
void and treated as if never made, to the extent that after giving effect to such conversion, the Holder together with the other
Attribution Parties collectively would beneficially own in excess of 4.99% (the “Maximum Percentage”) of the
shares of Common Stock outstanding immediately after giving effect to such conversion. For purposes of the foregoing sentence,
the aggregate number of shares of Common Stock beneficially owned by the Holder and the other Attribution Parties shall include
the number of shares of Common Stock held by the Holder and all other Attribution Parties plus the number of shares of Common Stock
issuable upon conversion of this Note with respect to which the determination of such sentence is being made, but shall exclude
shares of Common Stock which would be issuable upon (A) conversion of the remaining, nonconverted portion of this Note beneficially
owned by the Holder or any of the other Attribution Parties and (B) exercise or conversion of the unexercised or nonconverted portion
of any other securities of the Company (including, without limitation, any convertible notes or convertible preferred stock or
warrants, including, without limitation, the Warrants) beneficially owned by the Holder or any other Attribution Party subject
to a limitation on conversion or exercise analogous to the limitation contained in this Section 3(d)(i). For purposes of this Section
3(d)(i), beneficial ownership shall be calculated in accordance with Section 13(d) of the 1934 Act. For purposes of determining
the number of outstanding shares of Common Stock the Holder may acquire upon the conversion of this Note without exceeding the
Maximum Percentage, the Holder may rely on the number of outstanding shares of Common Stock as reflected in (x) the Company’s
most recent Annual Report on Form 10-K, Quarterly Report on Form 10-Q, Current Report on Form 8-K or other public filing with the
SEC, as the case may be, (y) a more recent public announcement by the Company or (z) any other written notice by the Company or
the Transfer Agent, if any, setting forth the number of shares of Common Stock outstanding (the “Reported Outstanding
Share Number”). If the Company receives a Conversion Notice from the Holder at a time when the actual number of outstanding
shares of Common Stock is less than the Reported Outstanding Share Number, the Company shall notify the Holder in writing of the
number of shares of Common Stock then outstanding and, to the extent that such Conversion Notice would otherwise cause the Holder’s
beneficial ownership, as determined pursuant to this Section 3(d)(i), to exceed the Maximum Percentage, the Holder must notify
the Company of a reduced number of shares of Common Stock to be purchased pursuant to such Conversion Notice. 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
or by electronic mail to the Holder the number of shares of Common Stock then outstanding. In any case, the number of outstanding
shares of Common Stock shall be determined after giving effect to the conversion or exercise of securities of the Company, including
this Note, by the Holder and any other Attribution Party since the date as of which the Reported Outstanding Share Number was reported.
In the event that the issuance of shares of Common Stock to the Holder upon conversion of this Note results in the Holder and the
other Attribution Parties being deemed to beneficially own, in the aggregate, more than the Maximum Percentage of the number of
outstanding shares of Common Stock (as determined under Section 13(d) of the 1934 Act), the number of shares so issued by which
the Holder’s and the other Attribution Parties’ aggregate beneficial ownership exceeds the Maximum Percentage (the
“Excess Shares”) shall be deemed null and void and shall be cancelled ab initio, and the Holder shall not have
the power to vote or to transfer the Excess Shares. Upon delivery of a written notice to the Company, the Holder may from time
to time increase (with such increase not effective until the sixty-first (61st) day after delivery of such notice) or
decrease the Maximum Percentage to any other percentage not in excess of 9.99% as specified in such notice; provided that (i) any
such increase in the Maximum Percentage will not be effective until the sixty-first (61st) day after such notice is
delivered to the Company and (ii) any such increase or decrease will apply only to the Holder and the other Attribution Parties
and not to any other holder of Notes that is not an Attribution Party of the Holder. For purposes of clarity, the shares of Common
Stock issuable pursuant to the terms of this Note in excess of the Maximum Percentage shall not be deemed to be beneficially owned
by the Holder for any purpose including for purposes of Section 13(d) or Rule 16a-1(a)(1) of the 1934 Act. No prior inability to
convert this Note 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. The provisions of this paragraph shall be construed and implemented
in a manner otherwise than in strict conformity with the terms of this Section 3(d)(i) to the extent necessary to correct this
paragraph (or any portion of this paragraph) which may be defective or inconsistent with the intended beneficial ownership limitation
contained in this Section 3(d)(i) or to make changes or supplements necessary or desirable to properly give effect to such limitation.
The limitation contained in this paragraph may not be waived and shall apply to a successor holder of this Note.

 

    6

     

    

 

(ii) Principal
Market Regulation The Company shall not issue any shares of Common Stock upon conversion of this Note or otherwise pursuant
to the terms of this Note (taken together with the issuance of such shares upon the exercise of the Warrants) if the issuance of
such shares of Common Stock would exceed the aggregate number of shares of Common Stock which the Company may issue upon conversion
of the Notes or otherwise pursuant to the terms of this Note or the Warrants (as the case may be) without breaching the Company’s
obligations under the rules or regulations of the Principal Market (the number of shares which may be issued without violating
such rules and regulations, including rules related to the aggregate of offerings under NASDAQ Listing Rule 5635(d), the “Exchange
Cap”), except that such limitation shall not apply in the event that the Company (A) obtains the approval of its stockholders
as required by the applicable rules of the Principal Market for issuances of shares of Common Stock in excess of such amount or
(B) obtains a written opinion from counsel to the Company that such approval is not required, which opinion shall be reasonably
satisfactory to the Holder. Until such approval or such written opinion is obtained, no Buyer shall be issued in the aggregate,
upon conversion or exercise (as the case may be) of any Notes or any of the Warrants or otherwise pursuant to the terms of the
Notes or the Warrants, shares of Common Stock in an amount greater than the product of (i) the Exchange Cap as of the Issuance
Date multiplied by (ii) the quotient of (1) the original principal amount of Notes issued to such Buyer pursuant to the Securities
Purchase Agreement on the Closing Date (as defined in the Securities Purchase Agreement) divided by (2) the aggregate original
principal amount of all Notes issued to the Buyers pursuant to the Securities Purchase Agreement on the Closing Date (with respect
to each Buyer, the “Exchange Cap Allocation”). In the event that any Buyer shall sell or otherwise transfer
any of such Buyer’s Notes, the transferee shall be allocated a pro rata portion of such Buyer’s Exchange Cap Allocation
with respect to such portion of such Notes so transferred, and the restrictions of the prior sentence shall apply to such transferee
with respect to the portion of the Exchange Cap Allocation so allocated to such transferee. Upon conversion and exercise in full
of a holder’s Notes and Warrants, the difference (if any) between such holder’s Exchange Cap Allocation and the number
of shares of Common Stock actually issued to such holder upon such holder’s conversion in full of such Notes and such holder’s
exercise in full of such Warrants shall be allocated, to the respective Exchange Cap Allocations of the remaining holders of Notes
and related Warrants on a pro rata basis in proportion to the shares of Common Stock underlying the Notes and related Warrants
then held by each such holder of Notes and related Warrants. At any time after tenth (10th) Trading Day after the Stockholder
Meeting Deadline (as defined in the Securities Purchase Agreement), in the event that the Company is prohibited from issuing shares
of Common Stock pursuant to this Section 3(d)(i) (the “Exchange Cap Shares”), the Company shall pay cash in
exchange for the cancellation of such portion of this Note convertible into such Exchange Cap Shares at a price equal to the sum
of (i) the product of (x) such number of Exchange Cap 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
Exchange Cap Shares to the Company and ending on the date of such issuance and payment under this Section 3(d)(i) and (ii) to the
extent of any Buy-In related thereto, any Buy-In Payment Amount, any brokerage commissions and other out-of-pocket expenses, if
any, of the Holder incurred in connection therewith (collectively, the “Exchange Cap Share Cancellation Amount”).

(e) Right
of Alternate Conversion Upon an Event of Default.

 

(i) General.
Subject to Section 3(d), at any time at any time after the occurrence of an Event of Default (regardless of whether such Event
of Default has been cured or if the Holder has delivered an Event of Default Redemption Notice to the Company), the Holder may,
at the Holder’s option, convert (each, an “Alternate Conversion”, and the date of such Alternate Conversion,
each, an “Alternate Conversion Date”) all, or any part of, the Conversion Amount (such portion of the Conversion
Amount subject to such Alternate Conversion, the “Alternate Conversion Amount”) into shares of Common Stock
at the Alternate Conversion Price.

 

(ii) Mechanics
of Alternate Conversion. On any Alternate Conversion Date, the Holder may voluntarily convert any Alternate Conversion Amount
pursuant to Section 3(c) (with “Alternate Conversion Price” replacing “Conversion Price” for all purposes
hereunder with respect to such Alternate Conversion and with “Redemption Premium of the Conversion Amount” replacing
“Conversion Amount” in clause (x) of the definition of Conversion Rate above with respect to such Alternate Conversion)
by designating in the Conversion Notice delivered pursuant to this Section 3(e) of this Note that the Holder is electing to use
the Alternate Conversion Price for such conversion; provided that in the event of the Conversion Floor Price Condition, on the
applicable Alternate Conversion Date the Company shall also deliver to the Holder the applicable Alternate Conversion Floor Amount.
Notwithstanding anything to the contrary in this Section 3(e), but subject to Section 3(d), until the Company delivers shares of
Common Stock representing the applicable Alternate Conversion Amount to the Holder, such Alternate Conversion Amount may be converted
by the Holder into shares of Common Stock pursuant to Section 3(c) without regard to this Section 3(e).

(b) Notice
of an Event of Default; Redemption Right. Upon the occurrence of an Event of Default with respect to this Note or any Other
Note, the Company shall within two (2) Business Day deliver written notice thereof via facsimile or electronic mail 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 (regardless of whether 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
12. 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 3(e), 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 a partial redemption of this Note pursuant hereto, the Principal amount redeemed shall be deducted from the Installment
Amount(s) relating to the applicable Installment Date(s) as set forth in the Event of Default Redemption Notice. 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. Any redemption upon an Event of Default shall not constitute an election of remedies by the Holder,
and all other rights and remedies of the Holder shall be preserved.

(c) Mandatory
Redemption upon Bankruptcy Event of Default. Notwithstanding anything to the contrary herein, and notwithstanding any conversion
that is then required or in process, upon any Bankruptcy Event of Default, whether occurring prior to or following the Maturity
Date, the Company shall immediately pay to the Holder an amount in cash representing (i) all outstanding Principal, accrued and
unpaid Interest and accrued and unpaid Late Charges on such Principal and Interest, multiplied by (ii) the Redemption Premium,
in addition to any and all other amounts due hereunder, without the requirement for any notice or demand or other action by the
Holder or any other person or entity, provided that the Holder may, in its sole discretion, waive such right to receive payment
upon a Bankruptcy Event of Default, in whole or in part, and any such waiver shall not affect any other rights of the Holder hereunder,
including any other rights in respect of such Bankruptcy Event of Default, any right to conversion, and any right to payment of
the Event of Default Redemption Price or any other Redemption Price, as applicable.

 

5. RIGHTS
UPON FUNDAMENTAL TRANSACTION.

 

(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 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 and security 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 Common Stock (or other securities, cash, assets or other property (except such items still issuable under
Sections 6 and 15, 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. The provisions of this Section 5 shall apply similarly and equally to successive Fundamental
Transactions and shall be applied without regard to any limitations on the conversion of this Note.

 

    13

     

    

 

(b) Notice
of a Change of Control; Redemption Right. No sooner than twenty (20) Trading Days nor later than ten (10) Trading Days prior
to the consummation of a Change of Control (the “Change of Control Date”), but not prior to the public announcement
of such Change of Control, the Company shall deliver written notice thereof via facsimile or electronic mail and overnight courier
to the Holder (a “Change of Control Notice”). At any time during the period beginning after the Holder’s
receipt of a Change of Control Notice or the Holder becoming aware of a Change of Control if a Change of Control Notice is not
delivered to the Holder in accordance with the immediately preceding sentence (as applicable) and ending on twenty (20) Trading
Days after the later of (A) the date of consummation of such Change of Control or (B) the date of receipt of such Change of Control
Notice or (C) the date of the announcement of such Change of Control, the Holder may require the Company to redeem all or any portion
of this Note by delivering written notice thereof (“Change of Control Redemption Notice”) to the Company, which
Change of Control Redemption Notice shall indicate the Conversion Amount the Holder is electing to redeem. The portion of this
Note subject to redemption pursuant to this Section 5 shall be redeemed by the Company in cash at a price equal to the greatest
of (i) the product of (w) the Change of Control Redemption Premium multiplied by (y) the Conversion Amount being redeemed, (ii)
the product of (x) the Change of Control Redemption Premium multiplied by (y) the product of (A) the Conversion Amount being redeemed
multiplied by (B) the quotient determined by dividing (I) the greatest Closing Sale Price of the shares of Common Stock during
the period beginning on the date immediately preceding the earlier to occur of (1) the consummation of the applicable Change of
Control and (2) the public announcement of such Change of Control and ending on the date the Holder delivers the Change of Control
Redemption Notice by (II) the Conversion Price then in effect and (iii) the product of (y) the Change of Control Redemption Premium
multiplied by (z) the product of (A) the Conversion Amount being redeemed multiplied by (B) the quotient of (I) the aggregate cash
consideration and the aggregate cash value of any non-cash consideration per share of Common Stock to be paid to the holders of
the shares of Common Stock upon consummation of such Change of Control (any such non-cash consideration constituting publicly-traded
securities shall be valued at the highest of the Closing Sale Price of such securities as of the Trading Day immediately prior
to the consummation of such Change of Control, the Closing Sale Price of such securities on the Trading Day immediately following
the public announcement of such proposed Change of Control and the Closing Sale Price of such securities on the Trading Day immediately
prior to the public announcement of such proposed Change of Control) divided by (II) the Conversion Price then in effect (the “Change
of Control Redemption Price”). Redemptions required by this Section 5 shall be made in accordance with the provisions
of Section 12 and shall have priority to payments to stockholders in connection with such Change of Control. To the extent redemptions
required by this Section 5(a) 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
5, but subject to Section 3(d), until the Change of Control Redemption Price (together with any Late Charges thereon) is paid in
full, the Conversion Amount submitted for redemption under this Section 5(a) (together with any Late Charges thereon) may be converted,
in whole or in part, by the Holder into Common Stock pursuant to Section 3. In the event of a partial redemption of this Note pursuant
hereto, the Principal amount redeemed shall be deducted from the Installment Amount(s) relating to the applicable Installment Date(s)
as set forth in the Change of Control Redemption Notice. In the event of the Company’s redemption of any portion of this
Note under this Section 5(a), 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 5(a) 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.

6. RIGHTS
UPON ISSUANCE OF PURCHASE RIGHTS AND OTHER CORPORATE EVENTS.

 

(a) Purchase
Rights. In addition to any adjustments pursuant to Section 7 below, 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 all or substantially
all of the record holders of any class of Common Stock (the “Purchase Rights”), then the Holder will be entitled
to acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights which the Holder could have acquired
if the Holder had held the number of shares of Common Stock acquirable upon complete conversion of this Note (without taking into
account any limitations or restrictions on the convertibility of this Note and assuming for such purpose that the Note was converted
at the Alternate Conversion Price as of the applicable record date) immediately prior to 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
shares of Common Stock are to be determined for the grant, issue or sale of such Purchase Rights (provided, however,
that to the extent that the Holder’s right to participate in any such Purchase Right would result in the Holder and the other
Attribution Parties exceeding the Maximum Percentage, then the Holder shall not be entitled to participate in such Purchase Right
to the extent of the Maximum Percentage (and shall not be entitled to beneficial ownership of such shares of Common Stock as a
result of such Purchase Right (and beneficial ownership) to the extent of any such excess) and such Purchase Right to such extent
shall be held in abeyance (and, if such Purchase Right has an expiration date, maturity date or other similar provision, such term
shall be extended by such number of days held in abeyance, if applicable) for the benefit of the Holder until such time or times,
if ever, as its right thereto would not result in the Holder and the other Attribution Parties exceeding the Maximum Percentage,
at which time or times the Holder shall be granted such right (and any Purchase Right granted, issued or sold on such initial Purchase
Right or on any subsequent Purchase Right held similarly in abeyance (and, if such Purchase Right has an expiration date, maturity
date or other similar provision, such term shall be extended by such number of days held in abeyance, if applicable)) to the same
extent as if there had been no such limitation).

 

(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 ensure that the Holder will thereafter have the right to receive upon a conversion of this Note, at the Holder’s option
(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. The provisions
of this Section 6 shall apply similarly and equally to successive Corporate Events and shall be applied without regard to any limitations
on the conversion or redemption of this Note.

 

    15

     

    

 

7. RIGHTS
UPON ISSUANCE OF OTHER SECURITIES.

 

(a) Adjustment
of Conversion Price upon Issuance of Common Stock. If and whenever on or after the Subscription Date the Company grants, issues
or sells (or enters into any agreement to grant, issue or sell), or in accordance with this Section 7(a) is deemed to have granted,
issued or sold, any shares of Common Stock (including the issuance or sale of shares of Common Stock owned or held by or for the
account of the Company, but excluding any Excluded Securities issued or sold or deemed to have been issued or sold) for a consideration
per share (the “New Issuance Price”) less than a price equal to the Conversion Price in effect immediately prior
to such issuance or sale or deemed issuance or sale (such Conversion Price then in effect is referred to herein as the “Applicable
Price”) (the foregoing a “Dilutive Issuance”), then, immediately after such Dilutive Issuance, the
Conversion Price then in effect shall be reduced to an amount equal to the New Issuance Price. For all purposes of the foregoing
(including, without limitation, determining the adjusted Conversion Price and the New Issuance Price under this Section 7(a)),
the following shall be applicable:

 

(i) Issuance
of Options. If the Company in any manner grants, issues or sells (or enters into any agreement to grant, issue or sell) any
Options and the lowest price per share for which one share of Common Stock is at any time issuable upon the exercise of any such
Option or upon conversion, exercise or exchange of any Convertible Securities issuable upon exercise of any such Option or otherwise
pursuant to the terms thereof is less than the Applicable Price, then such share of Common Stock shall be deemed to be outstanding
and to have been issued and sold by the Company at the time of the granting, issuance or sale of such Option for such price per
share. For purposes of this Section 7(a)(i), the “lowest price per share for which one share of Common Stock is at any time
issuable upon the exercise of any such Option or upon conversion, exercise or exchange of any Convertible Securities issuable upon
exercise of any such Option or otherwise pursuant to the terms thereof” shall be equal to (1) the lower of (x) the sum of
the lowest amounts of consideration (if any) received or receivable by the Company with respect to any one share of Common Stock
upon the granting, issuance or sale of such Option, upon exercise of such Option and upon conversion, exercise or exchange of any
Convertible Security issuable upon exercise of such Option or otherwise pursuant to the terms thereof and (y) the lowest exercise
price set forth in such Option for which one share of Common Stock is issuable (or may become issuable assuming all possible market
conditions) upon the exercise of any such Options or upon conversion, exercise or exchange of any Convertible Securities issuable
upon exercise of any such Option or otherwise pursuant to the terms thereof, minus (2) the sum of all amounts paid or payable to
the holder of such Option (or any other Person) with respect to any one share of Common Stock upon the granting, issuance or sale
of such Option, upon exercise of such Option and upon conversion, exercise or exchange of any Convertible Security issuable upon
exercise of such Option or otherwise pursuant to the terms thereof plus the value of any other consideration consisting of cash,
debt forgiveness, assets or any other property received or receivable by, or benefit conferred on, the holder of such Option (or
any other Person). Except as contemplated below, no further adjustment of the Conversion Price shall be made upon the actual issuance
of such share of Common Stock or of such Convertible Securities upon the exercise of such Options or otherwise pursuant to the
terms thereof or upon the actual issuance of such shares of Common Stock upon conversion, exercise or exchange of such Convertible
Securities.

 

    16

     

    

 

(ii) Issuance
of Convertible Securities. If the Company in any manner issues or sells (or enters into any agreement to issue or sell) any
Convertible Securities and the lowest price per share for which one share of Common Stock is at any time issuable upon the conversion,
exercise or exchange thereof or otherwise pursuant to the terms thereof is less than the Applicable Price, then such share of Common
Stock shall be deemed to be outstanding and to have been issued and sold by the Company at the time of the issuance or sale of
such Convertible Securities for such price per share. For the purposes of this Section 7(a)(ii), the “lowest price per share
for which one share of Common Stock is at any time issuable (or may become issuable assuming all possible market conditions) upon
the conversion, exercise or exchange thereof or otherwise pursuant to the terms thereof” shall be equal to (1) the lower
of (x) the sum of the lowest amounts of consideration (if any) received or receivable by the Company with respect to one share
of Common Stock upon the issuance or sale of the Convertible Security and upon conversion, exercise or exchange of such Convertible
Security or otherwise pursuant to the terms thereof and (y) the lowest conversion price set forth in such Convertible Security
for which one share of Common Stock is issuable upon conversion, exercise or exchange thereof or otherwise pursuant to the terms
thereof minus (2) the sum of all amounts paid or payable to the holder of such Convertible Security (or any other Person) with
respect to any one share of Common Stock upon the issuance or sale of such Convertible Security plus the value of any other consideration
received or receivable consisting of cash, debt forgiveness, assets or other property by, or benefit conferred on, the holder of
such Convertible Security (or any other Person). Except as contemplated below, no further adjustment of the Conversion Price shall
be made upon the actual issuance of such shares of Common Stock upon conversion, exercise or exchange of such Convertible Securities
or otherwise pursuant to the terms thereof, and if any such issuance or sale of such Convertible Securities is made upon exercise
of any Options for which adjustment of the Conversion Price has been or is to be made pursuant to other provisions of this Section
7(a), except as contemplated below, no further adjustment of the Conversion Price shall be made by reason of such issuance or sale.

 

(iii) Change
in Option Price or Rate of Conversion. If the purchase or exercise price provided for in any Options, the additional consideration,
if any, payable upon the issue, conversion, exercise or exchange of any Convertible Securities, or the rate at which any Convertible
Securities are convertible into or exercisable or exchangeable for shares of Common Stock increases or decreases at any time (other
than proportional changes in conversion or exercise prices, as applicable, in connection with an event referred to in Section 7(b)
below), the Conversion Price in effect at the time of such increase or decrease shall be adjusted to the Conversion Price which
would have been in effect at such time had such Options or Convertible Securities provided for such increased or decreased purchase
price, additional consideration or increased or decreased conversion rate (as the case may be) at the time initially granted, issued
or sold. For purposes of this Section 7(a)(iii), if the terms of any Option or Convertible Security (including, without limitation,
any Option or Convertible Security that was outstanding as of the Subscription Date) are increased or decreased in the manner described
in the immediately preceding sentence, then such Option or Convertible Security and the shares of Common Stock deemed issuable
upon exercise, conversion or exchange thereof shall be deemed to have been issued as of the date of such increase or decrease.
No adjustment pursuant to this Section 7(a) shall be made if such adjustment would result in an increase of the Conversion Price
then in effect.

 

    17

     

    

 

(iv) Calculation
of Consideration Received. If any Option and/or Convertible Security and/or Adjustment Right is issued in connection with the
issuance or sale or deemed issuance or sale of any other securities of the Company (as determined by the Holder, the “Primary
Security”, and such Option and/or Convertible Security and/or Adjustment Right, the “Secondary Securities”),
together comprising one integrated transaction (or one or more transactions if such issuances or sales or deemed issuances or sales
of securities of the Company either (A) have at least one investor or purchaser in common, (B) are consummated in reasonable proximity
to each other and/or (C) are consummated under the same plan of financing), the aggregate consideration per share of Common Stock
with respect to such Primary Security shall be deemed to be equal to the difference of (x) the lowest price per share for which
one share of Common Stock was issued (or was deemed to be issued pursuant to Section 7(a)(i) or 7(a)(ii) above, as applicable)
in such integrated transaction solely with respect to such Primary Security, minus (y) with respect to such Secondary Securities,
the sum of (I) the Black Scholes Consideration Value of each such Option, if any, (II) the fair market value (as determined by
the Holder in good faith) or the Black Scholes Consideration Value, as applicable, of such Adjustment Right, if any, and (III)
the fair market value (as determined by the Holder) of such Convertible Security, if any, in each case, as determined on a per
share basis in accordance with this Section 7(a)(i). If any shares of Common Stock, Options or Convertible Securities are issued
or sold or deemed to have been issued or sold for cash, the consideration received therefor (for the purpose of determining the
consideration paid for such Common Stock, Option or Convertible Security, but not for the purpose of the calculation of the Black
Scholes Consideration Value) will be deemed to be the net amount of consideration received by the Company therefor. If any shares
of Common Stock, Options or Convertible Securities are issued or sold for a consideration other than cash, the amount of such consideration
received by the Company (for the purpose of determining the consideration paid for such Common Stock, Option or Convertible Security,
but not for the purpose of the calculation of the Black Scholes Consideration Value) will be the fair value of such consideration,
except where such consideration consists of publicly traded securities, in which case the amount of consideration received by the
Company for such securities will be the arithmetic average of the VWAPs of such security for each of the five (5) Trading Days
immediately preceding the date of receipt. If any shares of Common Stock, Options or Convertible Securities are issued to the owners
of the non-surviving entity in connection with any merger in which the Company is the surviving entity, the amount of consideration
therefor (for the purpose of determining the consideration paid for such Common Stock, Option or Convertible Security, but not
for the purpose of the calculation of the Black Scholes Consideration Value) will be deemed to be the fair value of such portion
of the net assets and business of the non-surviving entity as is attributable to such shares of Common Stock, Options or Convertible
Securities (as the case may be). The fair value of any consideration other than cash or publicly traded securities will be determined
jointly by the Company and the Holder. If such parties are unable to reach agreement within ten (10) days after the occurrence
of an event requiring valuation (the “Valuation Event”), the fair value of such consideration will be determined
within five (5) Trading Days after the tenth (10th) day following such Valuation Event by an independent, reputable
appraiser jointly selected by the Company and the Holder. The determination of such appraiser shall be final and binding upon all
parties absent manifest error and the fees and expenses of such appraiser shall be borne by the Company.

 

    18

     

    

 

(v) Record
Date. If the Company takes a record of the holders of shares of Common Stock for the purpose of entitling them (A) to receive
a dividend or other distribution payable in shares of Common Stock, Options or in Convertible Securities or (B) to subscribe for
or purchase shares of Common Stock, Options or Convertible Securities, then such record date will be deemed to be the date of the
issuance or sale of the shares of Common Stock deemed to have been issued or sold upon the declaration of such dividend or the
making of such other distribution or the date of the granting of such right of subscription or purchase (as the case may be).

 

(b) Adjustment
of Conversion Price upon Subdivision or Combination of Common Stock. Without limiting any provision of Section 6, Section
15 or Section 7(a), if the Company at any time on or after the Subscription Date subdivides (by any stock split, stock dividend,
stock combination, recapitalization or other similar transaction) 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 6, Section 15 or Section 7(a), if the Company at any time on or after the Subscription
Date combines (by any stock split, stock dividend, stock combination, recapitalization or other similar transaction) 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 7(b) shall become effective immediately
after the effective date of such subdivision or combination. If any event requiring an adjustment under this Section 7(b) occurs
during the period that a Conversion Price is calculated hereunder, then the calculation of such Conversion Price shall be adjusted
appropriately to reflect such event.

 

    19

     

    

 

(c) Holder’s
Right of Adjusted Conversion Price. In addition to and not in limitation of the other provisions of this Section 7, if the
Company in any manner issues or sells or enters into any agreement to issue or sell, any Common Stock, Options or Convertible Securities
(any such securities, “Variable Price Securities”), after the Subscription Date that are issuable pursuant to
such agreement or convertible into or exchangeable or exercisable for shares of Common Stock at a price which varies or may vary
with the market price of the shares of Common Stock, including by way of one or more reset(s) to a fixed price, but exclusive of
such formulations reflecting customary anti-dilution provisions (such as share splits, share combinations, share dividends and
similar transactions) (each of the formulations for such variable price being herein referred to as, the “Variable Price”),
the Company shall provide written notice thereof via facsimile and overnight courier to the Holder on the date of such agreement
and the issuance of such Convertible Securities or Options. From and after the date the Company enters into such agreement or issues
any such Variable Price Securities, the Holder shall have the right, but not the obligation, in its sole discretion to substitute
the Variable Price for the Conversion Price upon conversion of this Note by designating in the Conversion Notice delivered upon
any conversion of this Note that solely for purposes of such conversion the Holder is relying on the Variable Price rather than
the Conversion Price then in effect. The Holder’s election to rely on a Variable Price for a particular conversion of this
Note shall not obligate the Holder to rely on a Variable Price for any future conversion of this Note. In addition, from and after
the date the Company enters into such agreement or issues any such Variable Price Securities, for purposes of calculating the Installment
Conversion Price as of any time of determination, the “Conversion Price” as used therein shall mean the lower of (x)
the Conversion Price as of such time of determination and (y) the Variable Price as of such time of determination.

 

(d) Stock
Combination Event Adjustments. If at any time and from time to time on or after the Subscription Date there occurs any stock
split, stock dividend, stock combination recapitalization or other similar transaction involving the Common Stock (each, a “Stock
Combination Event”, and such date thereof, the “Stock Combination Event Date”) and the Event Market
Price is less than the Conversion Price then in effect (after giving effect to the adjustment in Section 7(b) above), then on the
sixteenth (16th) Trading Day immediately following such Stock Combination Event Date, the Conversion Price then in effect
on such sixteenth (16th) Trading Day (after giving effect to the adjustment in Section 7(b) above) shall be reduced
(but in no event increased) to the Event Market Price. For the avoidance of doubt, if the adjustment in the immediately preceding
sentence would otherwise result in an increase in the Conversion Price hereunder, no adjustment shall be made.

 

(e) Other
Events. In the event that the Company (or any Subsidiary) shall take any action to which the provisions hereof are not strictly
applicable, or, if applicable, would not operate to protect the Holder from dilution or if any event occurs of the type contemplated
by the provisions of this Section 7 but not expressly provided for by such provisions (including, without limitation, the granting
of stock appreciation rights, phantom stock rights or other rights with equity features), then the Company’s board of directors
shall in good faith determine and implement an appropriate adjustment in the Conversion Price so as to protect the rights of the
Holder, provided that no such adjustment pursuant to this Section 7(e) will increase the Conversion Price as otherwise determined
pursuant to this Section 7, provided further that if the Holder does not accept such adjustments as appropriately protecting its
interests hereunder against such dilution, then the Company’s board of directors and the Holder shall agree, in good faith,
upon an independent investment bank of nationally recognized standing to make such appropriate adjustments, whose determination
shall be final and binding absent manifest error and whose fees and expenses shall be borne by the Company.

 

    20

     

    

 

(f) Calculations.
All calculations under this Section 7 shall be made by rounding to the nearest cent or the nearest 1/100th of a
share, as applicable. The number of shares of Common Stock outstanding at any given time shall not include shares owned or held
by or for the account of the Company, and the disposition of any such shares shall be considered an issue or sale of Common Stock.

 

(g) Voluntary
Adjustment by Company. Subject to the rules and regulations of the Principal Market, the Company may at any time during the
term of this Note, with the prior written consent of the Required Holders (as defined in the Securities Purchase Agreement), reduce
the then current Conversion Price of each of the Notes to any amount and for any period of time deemed appropriate by the board
of directors of the Company.

 

8. INSTALLMENT
CONVERSION OR REDEMPTION.

 

(a) General.
On each applicable Installment Date, provided there has been no Equity Conditions Failure, the Company shall pay to the Holder
of this Note the applicable Installment Amount due on such date by converting such Installment Amount in accordance with this Section
8 (a “Installment Conversion”); provided, however, that the Company may, at its option following
notice to the Holder as set forth below, pay the Installment Amount by redeeming such Installment Amount in cash (a “Installment
Redemption”) or by any combination of an Installment Conversion and an Installment Redemption so long as all of the outstanding
applicable Installment Amount due on any Installment Date shall be converted and/or redeemed by the Company on the applicable Installment
Date, subject to the provisions of this Section 8. On the date which is the twenty-first (21st) Trading Day prior to each Installment
Date (each, an “Installment Notice Due Date”), the Company shall deliver written notice (each, a “Installment
Notice” and the date all of the holders receive such notice is referred to as to the “Installment Notice Date”),
to each holder of Notes and such Installment Notice shall (i) either (A) confirm that the applicable Installment Amount of such
holder’s Note shall be converted in whole pursuant to an Installment Conversion or (B) (1) state that the Company elects
to redeem for cash, or is required to redeem for cash in accordance with the provisions of the Notes, in whole or in part, the
applicable Installment Amount pursuant to an Installment Redemption and (2) specify the portion of such Installment Amount which
the Company elects or is required to redeem pursuant to an Installment Redemption (such amount to be redeemed in cash, the “Installment
Redemption Amount”) and the portion of the applicable Installment Amount, if any, with respect to which the Company will,
and is permitted to, effect an Installment Conversion (such amount of the applicable Installment Amount so specified to be so converted
pursuant to this Section 8 is referred to herein as the “Installment Conversion Amount”), which amounts when
added together, must at least equal the entire applicable Installment Amount and (ii) if the applicable Installment Amount is to
be paid, in whole or in part, pursuant to an Installment Conversion, certify that there is not then an Equity Conditions Failure
as of the applicable Installment Notice Date. Each Installment Notice shall be irrevocable. If the Company does not timely deliver
an Installment Notice in accordance with this Section 8 with respect to a particular Installment Date, then the Company shall be
deemed to have delivered an irrevocable Installment Notice confirming an Installment Conversion of the entire Installment Amount
payable on such Installment Date and shall be deemed to have certified that there is not then an Equity Conditions Failure in connection
with such Installment Conversion. Except as expressly provided in this Section 8(a), the Company shall convert and/or redeem the
applicable Installment Amount of this Note pursuant to this Section 8 and the corresponding Installment Amounts of the Other Notes
pursuant to the corresponding provisions of the Other Notes in the same ratio of the applicable Installment Amount being converted
and/or redeemed hereunder. The applicable Installment Conversion Amount (whether set forth in the applicable Installment Notice
or by operation of this Section 8) shall be converted in accordance with Section 8(b) and the applicable Installment Redemption
Amount shall be redeemed in accordance with Section 8(c).

 

    21

     

    

 

(b) Mechanics
of Installment Conversion. Subject to Section 3(d), if the Company delivers an Installment Notice or is deemed to have delivered
an Installment Notice certifying that such Installment Amount is being paid, in whole or in part, in an Installment Conversion
in accordance with Section 8(a), then the remainder of this Section 8(b) shall apply. The applicable Installment Conversion Amount,
if any, shall be converted on the applicable Installment Date at the applicable Installment Conversion Price and the Company shall,
on such Installment Date, (A) deliver to the Holder’s account with DTC such shares of Common Stock issued upon such conversion
(subject to the reduction contemplated by the immediately following sentence and, if applicable, the penultimate sentence of this
Section 8(b)) and (B) in the event of the Conversion Floor Price Condition, the Company shall deliver to the Holder the applicable
Conversion Installment Floor Amount, provided that the Equity Conditions are then satisfied (or waived in writing by the Holder)
on such Installment Date and an Installment Conversion is not otherwise prohibited under any other provision of this Note. If the
Company confirmed (or is deemed to have confirmed by operation of Section 8(a)) the conversion of the applicable Installment Conversion
Amount, in whole or in part, and there was no Equity Conditions Failure as of the applicable Installment Notice Date (or is deemed
to have certified that the Equity Conditions in connection with any such conversion have been satisfied by operation of Section
8(a)) but an Equity Conditions Failure occurred between the applicable Installment Notice Date and any time through the applicable
Installment Date (the “Interim Installment Period”), the Company shall provide the Holder a subsequent notice
to that effect. If there is an Equity Conditions Failure (which is not waived in writing by the Holder) during such Interim Installment
Period or an Installment Conversion is not otherwise permitted under any other provision of this Note, then, at the option of the
Holder designated in writing to the Company, the Holder may require the Company to do any one or more of the following: (i) the
Company shall redeem all or any part designated by the Holder of the unconverted Installment Conversion Amount (such designated
amount is referred to as the “Designated Redemption Amount”) and the Company shall pay to the Holder within
two (2) days of such Installment Date, by wire transfer of immediately available funds, an amount in cash equal to 110% of such
Designated Redemption Amount, and/or (ii) the Installment Conversion shall be null and void with respect to all or any part designated
by the Holder of the unconverted Installment Conversion Amount and the Holder shall be entitled to all the rights of a holder of
this Note with respect to such designated part of the Installment Conversion Amount; provided, however, the Conversion Price for
such designated part of such unconverted Installment Conversion Amount shall thereafter be adjusted to equal the lesser of (A)
the Installment Conversion Price as in effect on the date on which the Holder voided the Installment Conversion and (B) the Installment
Conversion Price that would be in effect on the date on which the Holder delivers a Conversion Notice relating thereto as if such
date was an Installment Date. If the Company fails to redeem any Designated Redemption Amount by the second (2nd) day following
the applicable Installment Date by payment of such amount by such date, then the Holder shall have the rights set forth in Section
12(a) as if the Company failed to pay the applicable Installment Redemption Price (as defined below) and all other rights under
this Note (including, without limitation, such failure constituting an Event of Default described in Section 4(a)(vi)). Notwithstanding
anything to the contrary in this Section 8(b), but subject to 3(d), until the Company delivers Common Stock representing the Installment
Conversion Amount to the Holder, the Installment Conversion Amount may be converted by the Holder into Common Stock pursuant to
Section 3. In the event that the Holder elects to convert the Installment Conversion Amount prior to the applicable Installment
Date as set forth in the immediately preceding sentence, the Installment Conversion Amount so converted shall be deducted from
the Installment Amount(s) relating to the applicable Installment Date(s) as set forth in the applicable Conversion Notice. The
Company shall pay any and all taxes that may be payable with respect to the issuance and delivery of any shares of Common Stock
in any Installment Conversion hereunder.

 

    22

     

    

 

(c) Mechanics
of Installment Redemption. If the Company elects or is required to effect an Installment Redemption, in whole or in part, in
accordance with Section 8(a), then the Installment Redemption Amount, if any, shall be redeemed by the Company in cash on the applicable
Installment Date by wire transfer to the Holder of immediately available funds in an amount equal to 105% of the applicable Installment
Redemption Amount (the “Installment Redemption Price”). If the Company fails to redeem such Installment Redemption
Amount on such Installment Date by payment of the Installment Redemption Price, then, at the option of the Holder designated in
writing to the Company (any such designation shall be a “Conversion Notice” for purposes of this Note), the
Holder may require the Company to convert all or any part of the Installment Redemption Amount at the Installment Conversion Price
(determined as of the date of such designation as if such date were an Installment Date). Conversions required by this Section
8(c) shall be made in accordance with the provisions of Section 3(c). Notwithstanding anything to the contrary in this Section
8(c), but subject to Section 3(d), until the Installment Redemption Price (together with any Late Charges thereon) is paid in full,
the Installment Redemption Amount (together with any Late Charges thereon) may be converted, in whole or in part, by the Holder
into Common Stock pursuant to Section 3. In the event the Holder elects to convert all or any portion of the Installment Redemption
Amount prior to the applicable Installment Date as set forth in the immediately preceding sentence, the Installment Redemption
Amount so converted shall be deducted from the Installment Amounts relating to the applicable Installment Date(s) as set forth
in the applicable Conversion Notice. Redemptions required by this Section 8(c) shall be made in accordance with the provisions
of Section 12.

 

(d) Deferred
Installment Amount. Notwithstanding any provision of this Section 8(d) to the contrary, the Holder may, at its option and in
its sole discretion, deliver a written notice to the Company no later than the Trading Day immediately prior to the applicable
Installment Date electing to have the payment of all or any portion of an Installment Amount payable on such Installment Date deferred
(such amount deferred, the “Deferral Amount”, and such deferral, each a “Deferral”) until
any subsequent Installment Date selected by the Holder, in its sole discretion, in which case, the Deferral Amount shall be added
to, and become part of, such subsequent Installment Amount and such Deferral Amount shall continue to accrue Interest hereunder.
Any notice delivered by the Holder pursuant to this Section 8(d) shall set forth (i) the Deferral Amount and (ii) the date that
such Deferral Amount shall now be payable.

 

(e) Acceleration
of Installment Amounts. Notwithstanding anything herein to the contrary, during the period commencing on an Installment Date
(a “Current Installment Date”) and ending on the Trading Day immediately prior to the next Installment Date
(each, an “Installment Period”), at the option of the Holder, at one or more times, the Holder may convert other
Installment Amounts (each, an “Acceleration”, and each such amount, an “Acceleration Amount”),
in whole or in part, at the Installment Conversion Price of such Current Installment Date in accordance with the conversion procedures
set forth in Section 3 hereunder, mutatis mutandis. Notwithstanding the foregoing, with respect to any given Installment
Period, the Holder may not elect to effect any Acceleration (a “Current Acceleration”) during such Installment
Period if the sum of (x) the Acceleration Amounts with respect to Accelerations previously consummated by the Holder during the
applicable Installment Period and (y) the Acceleration Amount of such Current Acceleration, collectively, exceeds the Installment
Amount with respect to such Current Installment Date.

9. REDEMPTIONS
AT THE COMPANY’S ELECTION.

 

(a) Company
Optional Redemption. At any time (x) if prior to the Applicable Date (as defined in the Securities Purchase Agreement), as
long as no Event of Default has occurred or is continuing or (y) if after the Applicable Date and (y) as long as no Equity Conditions
Failure then exists, the Company shall have the right to redeem all, but not less than all, of the Conversion Amount then remaining
under this Note (the “Company Optional Redemption Amount”) on the Company Optional Redemption Date (each as
defined below) (a “Company Optional Redemption”). The portion of this Note subject to redemption pursuant to
this Section 9(a) shall be redeemed by the Company in cash at a price (the “Company Optional Redemption Price”)
equal to 105% of the Conversion Amount being redeemed as of the Company Optional Redemption Date. The Company may exercise its
right to require redemption under this Section 9(a) by delivering a written notice thereof by facsimile or electronic mail and
overnight courier to all, but not less than all, of the holders of Notes (the “Company Optional Redemption Notice”
and the date all of the holders of Notes received such notice is referred to as the “Company Optional Redemption Notice
Date”). The Company may deliver only one Company Optional Redemption Notice hereunder and such Company Optional Redemption
Notice shall be irrevocable. 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 ten (10) Trading Days
nor more than twenty (20) Trading Days following the Company Optional Redemption Notice Date, (y) certify that there has been no
Event of Default or, if after the Applicable Date, no Equity Conditions Failure and (z) state the aggregate Conversion Amount of
the Notes which is being redeemed in such Company Optional Redemption from the Holder and all of the other holders of the Notes
pursuant to this Section 9(a) (and analogous provisions under the Other Notes) on the Company Optional Redemption Date. Notwithstanding
anything herein to the contrary, (i) if no Event of Default or, if after the Applicable Date, no Equity Conditions Failure has
occurred as of the Company Optional Redemption Notice Date but an Event of Default or, if after the Applicable Date, an Equity
Conditions Failure, as applicable, occurs at any time prior to the Company Optional Redemption Date, (A) the Company shall provide
the Holder a subsequent notice to that effect and (B) unless the Holder waives such Event of Default or Equity Conditions Failure,
as applicable, the Company Optional Redemption shall be cancelled and the applicable Company Optional Redemption Notice shall be
null and void and (ii) 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(a) shall be made in accordance with Section 12. In the event of the Company’s redemption of any portion of this Note under
this Section 9, 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 9 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. For the avoidance of doubt, the
Company shall have no right to effect a Company Optional Redemption if any Event of Default has occurred and continuing, but any
Event of Default shall have no effect upon the Holder’s right to convert this Note in its discretion.

 

(b) Pro
Rata Redemption Requirement. If the Company elects to cause a Company Optional Redemption of this Note pursuant to Section
9(a), then it must simultaneously take the same action with respect to all of the Other Notes.

 

    24

     

    

 

10. NONCIRCUMVENTION.
The Company hereby covenants and agrees that the Company will not, by amendment of its Certificate of Incorporation (as defined
in the Securities Purchase Agreement), Bylaws (as defined in the Securities Purchase Agreement) 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 or any other provision of this Note or the other Transaction Documents,
the Company (a) 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, and (b) 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.
Notwithstanding anything herein to the contrary, if after the sixty (60) calendar day anniversary of the Issuance Date, the Holder
is not permitted to convert this Note in full for any reason (other than pursuant to restrictions set forth in Section 3(d) hereof),
the Company shall use its best efforts to promptly remedy such failure, including, without limitation, obtaining such consents
or approvals as necessary to permit such conversion into shares of Common Stock.

 

11. RESERVATION
OF AUTHORIZED SHARES.

 

(a) Reservation.
So long as any Notes remain outstanding, the Company shall at all times reserve at least 200% of the number of shares of Common
Stock as shall from time to time be necessary to effect the conversion, including without limitation, Installment Conversions,
Alternate Conversions and Accelerations, of all of the Notes then outstanding (without regard to any limitations on conversions
and assuming such Notes remain outstanding until the Maturity Date) at the Alternate Conversion Price then in effect (the “Required
Reserve Amount”). The Required Reserve Amount (including, without limitation, each increase in the number of shares so
reserved) shall be allocated pro rata among the holders of the Notes based on the original principal amount of the Notes held by
each holder on the Closing Date or increase in the number of reserved shares, as the case may be (the “Authorized Share
Allocation”). In the event that a holder shall sell or otherwise transfer any of such holder’s Notes, each transferee
shall be allocated a pro rata portion of such holder’s Authorized Share Allocation. Any shares of Common Stock reserved and
allocated to any Person which ceases to hold any Notes shall be allocated to the remaining holders of Notes, pro rata based on
the principal amount of the Notes then held by such holders.

 

(b) Insufficient
Authorized Shares. If, notwithstanding Section 11(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 pursuant to the terms of this Note 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 “Authorized Failure Shares”), in lieu of delivering such Authorized 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 Authorized 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 Authorized Failure Shares to the Company and ending on the date
of such issuance and payment under this Section 11(a); 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 Authorized Failure Shares, any brokerage
commissions and other out-of-pocket expenses, if any, of the Holder incurred in connection therewith. Nothing contained in Section
11(a) or this Section 11(b) shall limit any obligations of the Company under any provision of the Securities Purchase Agreement.

 

    25

     

    

 

12. 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. If the Holder has submitted a Change
of Control Redemption Notice in accordance with Section 5(a), the Company shall deliver the applicable Change of Control Redemption
Price to the Holder in cash concurrently with the consummation of such Change of Control if such notice is received prior to the
consummation of such Change of Control and within five (5) Business Days after the Company’s receipt of such notice otherwise.
The Company shall deliver the applicable Installment Redemption Price to the Holder in cash on the applicable Installment Date.
The Company shall deliver the applicable Company Optional Redemption Price to the Holder in cash on the applicable Company Optional
Redemption Date. Notwithstanding anything herein to the contrary, in connection with any redemption hereunder at a time the Holder
is entitled to receive a cash payment under any of the other Transaction Documents, at the option of the Holder delivered in writing
to the Company, the applicable Redemption Price hereunder shall be increased by the amount of such cash payment owed to the Holder
under such other Transaction Document and, upon payment in full or conversion in accordance herewith, shall satisfy the Company’s
payment obligation under such other Transaction Document. 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
18(d)) representing the outstanding Principal which has not been redeemed. In the event that the Company does not pay the applicable
Redemption Price to the Holder within the time period required, at any time thereafter and until the Company pays such unpaid Redemption
Price in full, the Holder shall have the option, in lieu of redemption, to require the Company to promptly return to the Holder
all or any portion of this Note representing the Conversion Amount that was submitted for redemption and for which the applicable
Redemption Price (together with any Late Charges thereon) has not been paid. Upon the Company’s receipt of such notice, (x)
the applicable Redemption Notice shall be null and void with respect to such Conversion Amount, (y) the Company shall immediately
return this Note, or issue a new Note (in accordance with Section 18(d)), to the Holder, and in each case the principal amount
of this Note or such new Note (as the case may be) shall be increased by an amount equal to the difference between (1) the applicable
Redemption Price (as the case may be, and as adjusted pursuant to this Section 12, if applicable) minus (2) the Principal portion
of the Conversion Amount submitted for redemption and (z) the Conversion Price of this Note or such new Notes (as the case may
be) shall be automatically adjusted with respect to each conversion effected thereafter by the Holder to the lowest of (A) the
Conversion Price as in effect on the date on which the applicable Redemption Notice is voided, (B) the greater of (x) the Floor
Price and (y) 75% of the lowest Closing Bid Price of the Common Stock during the period beginning on and including the date on
which the applicable Redemption Notice is delivered to the Company and ending on and including the date on which the applicable
Redemption Notice is voided and (C) the greater of (x) the Floor Price and (y) 75% of the lowest VWAPs of the Common Stock during
the five (5) consecutive Trading Day period ending and including the applicable Conversion Date (it being understood and agreed
that all such determinations shall be appropriately adjusted for any stock dividend, stock split, stock combination or other similar
transaction during such period). 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.

 

    26

     

    

 

(b) Redemption
by Other Holders. Upon the Company’s receipt of notice from any of the holders of the Other Notes for redemption or repayment
as a result of an event or occurrence substantially similar to the events or occurrences described in Section 4(b) or Section 5(a)
(each, an “Other Redemption Notice”), the Company shall immediately, but no later than one (1) Business Day
of its receipt thereof, forward to the Holder by facsimile or electronic mail a copy of such notice. If the Company receives a
Redemption Notice and one or more Other Redemption Notices, during the seven (7) Business Day period beginning on and including
the date which is two (2) Business Days prior to the Company’s receipt of the Holder’s applicable Redemption Notice
and ending on and including the date which is two (2) Business Days after the Company’s receipt of the Holder’s applicable
Redemption Notice and the Company is unable to redeem all principal, interest and other amounts designated in such Redemption Notice
and such Other Redemption Notices received during such seven (7) Business Day period, then the Company shall redeem a pro rata
amount from each holder of the Notes (including the Holder) based on the principal amount of the Notes submitted for redemption
pursuant to such Redemption Notice and such Other Redemption Notices received by the Company during such seven (7) Business Day
period.

 

13. 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.

 

14. COVENANTS.
Until all of the Notes have been converted, redeemed or otherwise satisfied in accordance with their terms:

Indebtedness).

 

(c) Existence

cash equivalents (in whole or in part, whether by way of open market purchases, tender offers, private transactions or otherwise),
all or any portion of any Indebtedness (other than Permitted Indebtedness secured by Permitted Liens or the Notes) whether by way
of payment in respect of principal of (or premium, if any) or interest on, such Indebtedness if at the time such payment is due
or is otherwise made or, after giving effect to such payment, (i) an event constituting an Event of Default has occurred and is
continuing or (ii) an event that with the passage of time and without being cured would constitute an Event of Default has occurred
and is continuing.

 

(e) Restriction
on Redemption and Cash Dividends. The Company shall not, and the Company shall cause each of its Subsidiaries to not, directly

than (i) sales, leases, licenses, assignments, transfers, conveyances and other dispositions of such assets or rights by the Company
and its Subsidiaries in the ordinary course of business consistent with its past practice and (ii) sales of inventory and product
in the ordinary course of business.

 

(g) Maturity
of Indebtedness. The Company shall not, and the Company shall cause each of its Subsidiaries to not, directly or indirectly,
permit any Indebtedness of the Company or any of its Subsidiaries to mature or accelerate prior to the Maturity Date.

 

(h) Change
in Nature of Business.  The Company shall not, and the Company shall cause each of its Subsidiaries to not, directly
or indirectly, engage in any material line of business substantially different from those lines of business conducted by or publicly
contemplated to be conducted by the Company and each of its Subsidiaries on the Subscription Date or any business substantially
related or incidental thereto. The Company shall not, and the Company shall cause each of its Subsidiaries to not, directly or
indirectly, modify its or their corporate structure or purpose.

 

(i) Preservation
of Existence, Etc. The Company shall maintain and preserve, and cause each of its Subsidiaries to maintain and preserve, its
existence, rights and privileges, and become or remain, and cause each of its Subsidiaries to become or remain, duly qualified
and in good standing in each jurisdiction in which the character of the properties owned or leased by it or in which the transaction
of its business makes such qualification necessary.

 

(j) Maintenance
of Properties, Etc. The Company shall maintain and preserve, and cause each of its Subsidiaries to maintain and preserve, all
of its properties which are necessary or useful in the proper conduct of its business in good working order and condition, ordinary

    28

     

    

 

(l) Maintenance
of Insurance. The Company shall maintain, and cause each of its Subsidiaries to maintain, insurance with responsible and reputable
insurance companies or associations (including, without limitation, comprehensive general liability, hazard, rent and business
interruption insurance) with respect to its properties (including all real properties leased or owned by it) and business, in such

to, any transaction or series of related transactions (including, without limitation, the purchase, sale, lease, transfer or exchange
of property or assets of any kind or the rendering of services of any kind) with any affiliate, except transactions in the ordinary
course of business in a manner and to an extent consistent with past practice and necessary or desirable for the prudent operation
of its business, for fair consideration and on terms no less favorable to it or its Subsidiaries than would be obtainable in a
comparable arm’s length transaction with a Person that is not an affiliate thereof.

 

(n) Restricted
Issuances. The Company shall not, directly or indirectly, without the prior written consent of the holders of a majority in
aggregate principal amount of the Notes then outstanding, issue any Notes (other than as contemplated by the Securities Purchase
Agreement and the Notes) or any other securities that would cause a breach or default under the Notes or the Warrants.

 

(o) Independent
Investigation. At the request of the Holder either (x) at any time when an Event of Default has occurred and is continuing,
(y) upon the occurrence of an event that with the passage of time or giving of notice would constitute an Event of Default or (z)
at any time the Holder reasonably believes an Event of Default may have occurred or be continuing, the Company shall hire an independent,
reputable investment bank selected by the Company and approved by the Holder to investigate as to whether any breach of this Note
has occurred (the “Independent Investigator”). If the Independent Investigator determines that such breach of
this Note has occurred, the Independent Investigator shall notify the Company of such breach and the Company shall deliver written
notice to each holder of a Note of such breach. In connection with such investigation, the Independent Investigator may, during
normal business hours, inspect all contracts, books, records, personnel, offices and other facilities and properties of the Company
and its Subsidiaries and, to the extent available to the Company after the Company uses reasonable efforts to obtain them, the
records of its legal advisors and accountants (including the accountants’ work papers) and any books of account, records,
reports and other papers not contractually required of the Company to be confidential or secret, or subject to attorney-client
or other evidentiary privilege, and the Independent Investigator may make such copies and inspections thereof as the Independent
Investigator may reasonably request. The Company shall furnish the Independent Investigator with such financial and operating data
and other information with respect to the business and properties of the Company as the Independent Investigator may reasonably
request. The Company shall permit the Independent Investigator to discuss the affairs, finances and accounts of the Company with,
and to make proposals and furnish advice with respect thereto to, the Company’s officers, directors, key employees and independent
public accountants or any of them (and by this provision the Company authorizes said accountants to discuss with such Independent
Investigator the finances and affairs of the Company and any Subsidiaries), all at such reasonable times, upon reasonable notice,
and as often as may be reasonably requested.

 

    29

     

    

 

15. DISTRIBUTION
OF ASSETS. In addition to any adjustments pursuant to Section 7, if the Company shall declare or make any dividend or other
distributions of its assets (or rights to acquire its assets) to any or all holders of shares of Common Stock, by way of return
of capital or otherwise (including without limitation, any distribution of cash, stock or other securities, property or options
by way of a dividend, spin off, reclassification, corporate rearrangement, scheme of arrangement or other similar transaction)
(the “Distributions”), then the Holder will be entitled to such Distributions as if the Holder had held the
number of shares of Common Stock acquirable upon complete conversion of this Note (without taking into account any limitations
or restrictions on the convertibility of this Note and assuming for such purpose that the Note was converted at the Alternate Conversion
Price as of the applicable record date) immediately prior to the date on which a record is taken for such Distribution or, if no
such record is taken, the date as of which the record holders of Common Stock are to be determined for such Distributions (provided,
however, that to the extent that the Holder’s right to participate in any such Distribution would result in the Holder and
the other Attribution Parties exceeding the Maximum Percentage, then the Holder shall not be entitled to participate in such Distribution
to the extent of the Maximum Percentage (and shall not be entitled to beneficial ownership of such shares of Common Stock as a
result of such Distribution (and beneficial ownership) to the extent of any such excess) and the portion of such Distribution shall
be held in abeyance for the benefit of the Holder until such time or times, if ever, as its right thereto would not result in the
Holder and the other Attribution Parties exceeding the Maximum Percentage, at which time or times the Holder shall be granted such
Distribution (and any Distributions declared or made on such initial Distribution or on any subsequent Distribution held similarly
in abeyance) to the same extent as if there had been no such limitation).

 

16. AMENDING
THE TERMS OF THIS NOTE. Except for Section 3(d), which may not be amended, modified or waived by the parties hereto, the prior
written consent of the Holder shall be required for any change, waiver or amendment to this Note.

 

17. TRANSFER.
This Note and any shares of Common Stock issued upon conversion of this Note may be offered, sold, assigned or transferred by the
Holder without the consent of the Company, subject only to the provisions of Section 2(g) of the Securities Purchase Agreement.

 

18. 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
