 (a) On or prior to each Filing Date, the Company shall prepare and file with the Commission a “Shelf” Registration
Statement covering the resale of 115% of the Registrable Securities on such Filing Date for an offering to be made on a continuous basis pursuant to Rule 415. The Registration Statement shall be on Form S-2 (except if the Company is not then
eligible to register for resale the Registrable Securities on Form S-2, in which case such registration shall be on another appropriate form in accordance herewith) and shall contain (unless otherwise directed by the Holders) substantially the

Act as promptly as possible after the filing thereof, but in any event prior to the applicable Effectiveness Date, and shall use its reasonable best efforts to keep such Registration Statement continuously effective under the Securities Act until
all Registrable Securities covered by such Registration Statement have been sold or may be sold without volume restrictions pursuant to Rule 144(k) as determined by the counsel to the Company pursuant to a written opinion letter to such effect,
addressed and acceptable to the Company’s transfer agent and the affected Holders (the “Effectiveness Period”). The Company shall use its reasonable best efforts to have the Registration Statement declared effective as of 5:00
p.m. (New York time) on the date of effectiveness of the Registration Statement. The Company shall immediately notify the Holders via facsimile of the effectiveness of the Registration Statement on the same day that the Company receives notification
of the effectiveness from the Commission. Failure to so notify the Holder by 6:00 p.m. (New York time) on the day that the Company receives such notification shall be deemed an Event under Section 2(b). The Company shall furnish an electronic copy
of the Prospectus included in the Registration Statement to each Holder prior to 9:30 a.m. (New York time) on the day after the Company receives notification of the effectiveness from the Commission. 
  
 (b) If: (i) a Registration Statement is not filed on or prior to the
applicable Filing Date (if the Company files a Registration Statement without affording the Holders the opportunity to review and comment on the same as required by Section 3(a), the Company shall not be deemed to have satisfied this clause (i)), or
(ii) the Company fails to file with the Commission a request for acceleration in accordance with Rule 461 promulgated under the Securities Act (the “Acceleration Request”), within five Trading Days of the date that the Company is
notified (orally or in writing, whichever is earlier) by the Commission that a Registration Statement will not be “reviewed,” or not subject to further review, or (iii) prior to its Effectiveness Date, the Company fails to file a
pre-effective amendment and otherwise respond in writing to comments made by the Commission in respect of such Registration Statement within 10 Trading Days after the receipt of comments by or notice from the Commission that such amendment is
required in order for a Registration Statement to be declared effective, or (iv) a Registration Statement filed or required to be filed hereunder is not declared effective by the Commission by its Effectiveness Date, or (v) after the Effectiveness
Date, a Registration Statement ceases for any reason to remain continuously effective as to all Registrable Securities for which it is required to be effective, or the Holders are not permitted to utilize the Prospectus therein to resell such
Registrable Securities for 10 consecutive Trading Days but no more than an aggregate of 15 Trading Days during any 12-month period (which need not be consecutive Trading Days), or (vi) the Company fails to provide the Holder with a copy of the
Acceleration Request by 6:00 p.m. (New York time) on the day the Company provides such Acceleration Request to the 
  

 3 








 Commission (any such failure or breach being referred to as an “Event”, and for purposes of clause (i),
(iv) or (vi) the date on which such Event occurs, or for purposes of clause (ii) the date on which such five Trading Day period is exceeded, or for purposes of clause (iii) the date which such 10 calendar day period is exceeded, or for purposes of
clause (v) the date on which such 10 or 15 calendar day period, as applicable, is exceeded being referred to as “Event Date”), then in addition to any other rights the Holders may have hereunder or under applicable law, on each such
Event Date and on each monthly anniversary of each such Event Date (if the applicable Event shall not have been cured by such date) until the applicable Event is cured, the Company shall pay to each Holder an amount in cash, as partial liquidated
damages and not as a penalty, equal to 2.0% of the aggregate purchase price paid by such Holder pursuant to the Purchase Agreement for any Registrable Securities then held by such Holder. If the Company fails to pay any partial liquidated damages
pursuant to this Section 2(b) in full within seven Trading Days after the date payable, the Company will pay interest thereon at a rate of 18% per annum (or such lesser maximum amount that is permitted to be paid by applicable law) to the Holder,
accruing daily from the date such partial liquidated damages are due until such amounts, plus all such interest thereon, are paid in full. The partial liquidated damages pursuant to the terms hereof shall apply on a daily pro-rata basis for any
portion of a month prior to the cure of an Event. 
  
 3.
Registration Procedures. 
  
 In connection with the
Company’s registration obligations hereunder, the Company shall: 
  
 (a) Not less than five (5) Trading Days prior to the filing of each Registration Statement or any related Prospectus or any amendment or supplement thereto (including any document that would be incorporated or deemed to be incorporated
therein by reference), the Company shall, (i) furnish to each Holder copies of all such documents proposed to be filed, which documents (other than those incorporated or deemed to be incorporated by reference) will be subject to the reasonable
review of such Holders, and (ii) cause its officers and directors, counsel and independent certified public accountants to promptly respond to such inquiries from Holders as shall be necessary, in the reasonable opinion of respective counsel to
conduct a reasonable investigation within the meaning of the Securities Act. The Company shall not file the Registration Statement or any such Prospectus or any amendments or supplements thereto to which the Holders of 66.6% of the Registrable
Securities then outstanding shall reasonably object in good faith, provided that, the Company is notified of such objection in writing no later than five (5) Trading Days after the Holders have been so furnished copies of such documents. Each Holder
agrees to furnish to the Company a completed Questionnaire in the form attached to this Agreement as Annex B (a “Selling Holder Questionnaire”) not less than two Trading Days prior to the Filing Date or by the end of
the fourth Trading Day following the date on which such Holder receives draft materials in accordance with this Section 3. 
  
 (b) (i) Prepare and file with the Commission such amendments, including post-effective amendments, to a Registration Statement and the Prospectus used in
connection therewith as may be necessary to keep a Registration Statement continuously effective as to the applicable Registrable Securities for the Effectiveness Period and prepare and file with the Commission such additional Registration
Statements in order to register for resale under the 
  

 4 








 Securities Act all of the Registrable Securities; (ii) cause the related Prospectus to be amended or supplemented by any
required Prospectus supplement (subject to the terms of this Agreement), and as so supplemented or amended to be filed pursuant to Rule 424; (iii) respond as promptly as reasonably possible to any comments received from the Commission with respect
to a Registration Statement or any amendment thereto and as promptly as reasonably possible provide the Holders true and complete copies of all correspondence from and to the Commission relating to a Registration Statement; and (iv) comply in all
material respects with the provisions of the Securities Act and the Exchange Act with respect to the disposition of all Registrable Securities covered by a Registration Statement during the applicable period in accordance (subject to the terms of
this Agreement) with the intended methods of disposition by the Holders thereof set forth in such Registration Statement as so amended or in such Prospectus as so supplemented. 
  
 (c) If during the Effectiveness Period, the number of Registrable Securities at any time exceeds 90% of the number of shares
of Common Stock then registered in a Registration Statement, then the Company shall file as soon as reasonably practicable but in any case prior to the applicable Filing Date, an additional Registration Statement covering the resale by the Holders
of not less than 115% of the actual number of such Registrable Securities. 
  
 (d) Notify the Holders of Registrable Securities to be sold (which notice shall, pursuant to clauses (ii) through (vi) hereof, be accompanied by an instruction to suspend the use of the Prospectus until the requisite
changes have been made) as promptly as reasonably possible (and, in the case of (i)(A) below, not less than five (5) Trading Days prior to such filing) and (if requested by any such Person) confirm such notice in writing no later than one (1)
Trading Day following the day (i)(A) when a Prospectus or any Prospectus supplement or post-effective amendment to a Registration Statement is proposed to be filed; (B) when the Commission notifies the Company whether there will be a
“review” of such Registration Statement and whenever the Commission comments in writing on such Registration Statement (the Company shall provide true and complete copies thereof and all written responses thereto to each of the Holders who
request copies thereof); and (C) with respect to a Registration Statement or any post-effective amendment, when the same has become effective; (ii) of any request by the Commission or any other Federal or state governmental authority for amendments
or supplements to a Registration Statement or Prospectus or for additional information; (iii) of the issuance by the Commission or any other federal or state governmental authority of any stop order suspending the effectiveness of a Registration
Statement covering any or all of the Registrable Securities or the initiation of any Proceedings for that purpose; (iv) of the receipt by the Company of any notification with respect to the suspension of the qualification or exemption from
qualification of any of the Registrable Securities for sale in any jurisdiction, or the initiation or threatening of any Proceeding for such purpose; (v) of the occurrence of any event or passage of time that makes the financial statements included
in a Registration Statement ineligible for inclusion therein or any statement made in a Registration Statement or Prospectus or any document incorporated or deemed to be incorporated therein by reference untrue in any material respect or that
requires any revisions to a Registration Statement, Prospectus or other documents so that, in the case of a Registration Statement or the Prospectus, as the case may be, it will not contain any untrue statement of a material fact or omit to state
any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under 
  

 5 








 which they were made, not misleading; and (vi) the occurrence or existence of any pending corporate development with
respect to the Company that the Company’s Board of Directors reasonably believes may be material and therefore, in the reasonable determination of the Company’s Board, it is not in the best interests of the Company to disclose such
occurrence or event ; provided that any and all of such information shall remain confidential to each Holder until such information otherwise becomes public, unless a Holder, after consultation with its legal counsel, reasonably determines that such
disclosure is required by law, in which case Holder shall provide the Company with the opportunity to make such disclosure; provided, further, notwithstanding each Holder’s agreement to keep such information confidential, the
Holders make no acknowledgement that any such information is material, non-public information in advance of its receipt thereof. 
  
 (e) Use its reasonable best efforts to avoid the issuance of, or, if issued, obtain the withdrawal of (i) any order suspending the effectiveness of a
Registration Statement, or (ii) any suspension of the qualification (or exemption from qualification) of any of the Registrable Securities for sale in any jurisdiction, at the earliest practicable moment. 
  
 (f) Furnish to each Holder, without charge, at least one conformed copy of
each such Registration Statement and each amendment thereto, including financial statements and schedules, all documents incorporated or deemed to be incorporated therein by reference to the extent requested by such Person, and all exhibits to the
extent requested by such Person (including those previously furnished or incorporated by reference) promptly after the filing of such documents with the Commission. 
  
 (g) Promptly deliver to each Holder, without charge, as many copies of the Prospectus or Prospectuses (including each form
of prospectus) and each amendment or supplement thereto as such Persons may reasonably request in connection with resales by the Holder of Registrable Securities. Subject to the terms of this Agreement, the Company hereby consents to the use of such
Prospectus and each amendment or supplement thereto by each of the selling Holders in connection with the offering and sale of the Registrable Securities covered by such Prospectus and any amendment or supplement thereto, except after the giving on
any notice pursuant to Section 3(d). 
  
 (h) Prior to any resale
of Registrable Securities by a Holder, use its reasonable best efforts to register or qualify or cooperate with the selling Holders in connection with the registration or qualification (or exemption from the Registration or qualification) of such
Registrable Securities for the resale by the Holder under the securities or Blue Sky laws of such jurisdictions within the United States as any Holder reasonably requests in writing, to keep each registration or qualification (or exemption
therefrom) effective during the Effectiveness Period and to do any and all other acts or things reasonably necessary to enable the disposition in such jurisdictions of the Registrable Securities covered by each Registration Statement; provided, that
the Company shall not be required to qualify generally to do business in any jurisdiction where it is not then so qualified, subject the Company to any material tax in any such jurisdiction where it is not then so subject or file a general consent
to service of process in any such jurisdiction. 
  

 6 








 (i) If requested by the Holders, cooperate with the Holders to facilitate the timely preparation and
delivery of certificates representing Registrable Securities to be delivered to a transferee pursuant to a Registration Statement, which certificates shall be free, to the extent permitted by the Purchase Agreement, of all restrictive legends, and
to enable such Registrable Securities to be in such denominations and registered in such names as any such Holders may request. 
  
 (j) Upon the occurrence of any event or circumstance contemplated by Section 3(d), as promptly as reasonably possible under the circumstances taking into
account the Company’s good faith assessment of any adverse consequences to the Company and its stockholders of the premature disclosure of such event, prepare a supplement or amendment, including a post-effective amendment, to a Registration
Statement or a supplement to the related Prospectus or any document incorporated or deemed to be incorporated therein by reference, and file any other required document so that, as thereafter delivered, neither a Registration Statement nor such
Prospectus will 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 light of the circumstances under which they were made, not misleading. If
the Company notifies the Holders in accordance with clauses (ii) through (vi) of Section 3(d) above to suspend the use of any Prospectus until the requisite changes to such Prospectus have been made, then the Holders shall immediately suspend use of
such Prospectus. The Company shall use its reasonable best efforts to ensure that the use of the Prospectus may be resumed as promptly as is practicable in light of all of the circumstances. The Company shall be entitled to exercise its right under
this Section 3(j) to suspend the availability of a Registration Statement and Prospectus, subject to the payment of partial liquidated damages pursuant to Section 2(b), for a period not to exceed 60 Trading Days (which need not be consecutive days)
in any 12 consecutive month period. 
  
 (k) Comply with all
applicable rules and regulations of the Commission. 
  
 (l) The
Company may require each selling Holder to furnish to the Company a certified statement as to the number of shares of Common Stock beneficially owned by such Holder and, if required by the Commission, the person thereof that has voting and
dispositive control over the Shares. During any periods that the Company is unable to meet its obligations hereunder with respect to the registration of the Registrable Securities solely because any Holder fails to furnish such information within
three Trading Days of the Company’s request, any liquidated damages that are accruing at such time as to such Holder only shall be tolled and any Event that may otherwise occur solely because of such delay shall be suspended as to such Holder
only, until such information is delivered to the Company. 
  
 4.
Registration Expenses. All fees and expenses incident to the performance of or compliance with this Agreement by the Company shall be borne by the Company whether or not any Registrable Securities are sold pursuant to the Registration
Statement. The fees and expenses referred to in the foregoing sentence shall include, without limitation, (i) all registration and filing fees (including, without limitation, fees and expenses (A) with respect to filings required to be made with the
Trading Market on which the Common Stock is then listed for trading, and (B) in compliance with applicable state securities or Blue Sky laws reasonably agreed to by the Company in writing (including, without limitation, fees and disbursements of
counsel for the 
  

 7 








 Company in connection with Blue Sky qualifications or exemptions of the Registrable Securities and determination of the
eligibility of the Registrable Securities for investment under the laws of such jurisdictions as requested by the Holders), (ii) printing expenses (including, without limitation, expenses of printing certificates for Registrable Securities and of
printing prospectuses if the printing of prospectuses is reasonably requested by the holders of a majority of the Registrable Securities included in a Registration Statement), (iii) messenger, telephone and delivery expenses, (iv) fees and
disbursements of counsel for the Company, (v) Securities Act liability insurance, if the Company so desires such insurance, and (vi) fees and expenses of all other Persons retained by the Company in connection with the consummation of the
transactions contemplated by this Agreement. In addition, the Company shall be responsible for all of its internal expenses incurred in connection with the consummation of the transactions contemplated by this Agreement (including, without
limitation, all salaries and expenses of its officers and employees performing legal or accounting duties), the expense of any annual audit and the fees and expenses incurred in connection with the listing of the Registrable Securities on any
securities exchange as required hereunder. In no event shall the Company be responsible for any broker or similar commissions or, except to the extent provided for in the Transaction Documents, any legal fees or other costs of the Holders.

  
 5. Indemnification. 
  
 (a) Indemnification by the Company. The Company shall,
notwithstanding any termination of this Agreement, indemnify and hold harmless each Holder, the officers, directors, agents, brokers (including brokers who offer and sell Registrable Securities as principal as a result of a pledge or any failure to
perform under a margin call of Common Stock), investment advisors and employees of each of them, each Person who controls any such Holder (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) and the officers,
directors, agents and employees of each such controlling Person, to the fullest extent permitted by applicable law, from and against any and all losses, claims, damages, liabilities, costs (including, without limitation, reasonable attorneys’
fees) and expenses (collectively, “Losses”), as incurred, arising out of or relating to any untrue or alleged untrue statement of a material fact contained in a Registration Statement, any Prospectus or any form of prospectus or in
any amendment or supplement thereto or in any preliminary prospectus, or arising out of or relating to any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein (in the case of any
Prospectus or form of prospectus or supplement thereto, in light of the circumstances under which they were made) not misleading, except to the extent, but only to the extent, that (i) such untrue statements or omissions are based solely upon
information regarding such Holder furnished in writing to the Company by such Holder expressly for use therein, or to the extent that such information relates to such Holder or such Holder’s proposed method of distribution of Registrable
Securities and was reviewed and expressly approved in writing by such Holder expressly for use in a Registration Statement, such Prospectus or such form of Prospectus or in any amendment or supplement thereto (it being understood that the Holder has
approved Annex A hereto for this purpose) or (ii) in the case of an occurrence of an event of the type specified in Section 3(d)(ii)-(vi), the use by such Holder of an outdated or defective Prospectus after the Company has notified such Holder in
writing that the Prospectus is outdated or defective and prior to the receipt by such Holder of the Advice contemplated in Section 6(d). The Company shall notify the Holders promptly of the institution, threat or assertion of any Proceeding arising
from or in connection with the transactions contemplated by this Agreement of which the Company is aware. 
  

 8 








 (b) Indemnification by Holders. Each Holder shall, severally and not jointly, indemnify and hold
harmless the Company, its directors, officers, agents and employees, each Person who controls the Company (within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act), and the directors, officers, agents or employees
of such controlling Persons, to the fullest extent permitted by applicable law, from and against all Losses, as incurred, to the extent arising out of or based solely upon: (x) such Holder’s failure to comply with the prospectus delivery
requirements of the Securities Act or (y) any untrue or alleged untrue statement of a material fact contained in any Registration Statement, any Prospectus, or any form of prospectus, or in any amendment or supplement thereto or in any preliminary
prospectus, or arising out of or relating to any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading (i) to the extent, but only to the extent, that such untrue
statement or omission is contained in any information so furnished in writing by such Holder to the Company specifically for inclusion in such Registration Statement or such Prospectus or (ii) to the extent that (1) such untrue statements or
omissions are based solely upon information regarding such Holder furnished in writing to the Company by such Holder expressly for use therein, or to the extent that such information relates to such Holder or such Holder’s proposed method of
distribution of Registrable Securities and was reviewed and expressly approved in writing by such Holder expressly for use in the Registration Statement (it being understood that the Holder has approved Annex A hereto for this purpose), such
Prospectus or such form of Prospectus or in any amendment or supplement thereto or (2) in the case of an occurrence of an event of the type specified in Section 3(d)(ii)-(vi), the use by such Holder of an outdated or defective Prospectus after the
Company has notified such Holder in writing that the Prospectus is outdated or defective and prior to the receipt by such Holder of the Advice contemplated in Section 6(d). In no event shall the liability of any selling Holder hereunder be greater
in amount than the dollar amount of the net proceeds received by such Holder upon the sale of the Registrable Securities giving rise to such indemnification obligation. 
  
 (c) Conduct of Indemnification Proceedings. If any Proceeding shall be brought or asserted against any Person
entitled to indemnity hereunder (an “Indemnified Party”), such Indemnified Party shall promptly notify the Person from whom indemnity is sought (the “Indemnifying Party”) in writing, and the Indemnifying Party shall
have the right to assume the defense thereof, including the employment of counsel reasonably satisfactory to the Indemnified Party and the payment of all fees and expenses incurred in connection with defense thereof; provided, that the failure of
any Indemnified Party to give such notice shall not relieve the Indemnifying Party of its obligations or liabilities pursuant to this Agreement, except (and only) to the extent that it shall be finally determined by a court of competent jurisdiction
(which determination is not subject to appeal or further review) that such failure shall have prejudiced the Indemnifying Party. 
  
 An Indemnified Party shall have the right to employ separate counsel in any such Proceeding and to participate in the defense thereof, but the fees and
expenses of such counsel shall be at the expense of such Indemnified Party or Parties unless: (1) the Indemnifying Party 
  

 9 








 has agreed in writing to pay such fees and expenses; (2) the Indemnifying Party shall have failed promptly to assume the
defense of such Proceeding and to employ counsel reasonably satisfactory to such Indemnified Party in any such Proceeding; or (3) the named parties to any such Proceeding (including any impleaded parties) include both such Indemnified Party and the
Indemnifying Party, and such Indemnified Party shall reasonably believe that a material conflict of interest is likely to exist if the same counsel were to represent such Indemnified Party and the Indemnifying Party (in which case, if such
Indemnified Party notifies the Indemnifying Party in writing that it elects to employ separate counsel at the expense of the Indemnifying Party, the Indemnifying Party shall not have the right to assume the defense thereof and the reasonable fees
and expenses of one separate counsel shall be at the expense of the Indemnifying Party). The Indemnifying Party shall not be liable for any settlement of any such Proceeding effected without its written consent, which consent shall not be
unreasonably withheld. No Indemnifying Party shall, without the prior written consent of the Indemnified Party, effect any settlement of any pending Proceeding in respect of which any Indemnified Party is a party, unless such settlement includes an
unconditional release of such Indemnified Party from all liability on claims that are the subject matter of such Proceeding. 
  
 Subject to the terms of this Agreement, all reasonable fees and expenses of the Indemnified Party (including reasonable fees and expenses to the extent
incurred in connection with investigating or preparing to defend such Proceeding in a manner not inconsistent with this Section) shall be paid to the Indemnified Party, as incurred, within ten (10) Trading Days of written notice thereof to the
Indemnifying Party; provided, that the Indemnified Party shall promptly reimburse the Indemnifying Party for that portion of such fees and expenses applicable to such actions for which such Indemnified Party is not entitled to indemnification
hereunder, determined based upon the relative faults of the parties. 
  
 (d) Contribution. If a claim for indemnification under Section 5(a) or 5(b) is unavailable to an Indemnified Party (by reason of public policy or otherwise), then each 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, in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party and Indemnified Party in connection with the
actions, statements or omissions that resulted in such Losses as well as any other relevant equitable considerations. The relative fault of such Indemnifying Party and Indemnified Party shall be determined by reference to, among other things,
whether any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission of a material fact, has been taken or made by, or relates to information supplied by, such Indemnifying Party or
Indemnified Party, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such action, statement or omission. The amount paid or payable by a party as a result of any Losses shall be deemed to
include, subject to the limitations set forth in this Agreement, any reasonable attorneys’ or other reasonable fees or expenses incurred by such party in connection with any Proceeding to the extent such party would have been indemnified for
such fees or expenses if the indemnification provided for in this Section was available to such party in accordance with its terms. 
  
 The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 5(d) were determined by pro rata allocation or
by any other method of allocation 
  

 10 








 that does not take into account the equitable considerations referred to in the immediately preceding paragraph.
Notwithstanding the provisions of this Section 5(d), no Holder shall be required to contribute, in the aggregate, any amount in excess of the amount by which the proceeds actually received by such Holder from the sale of the Registrable Securities
subject to the Proceeding exceeds the amount of any damages that such Holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission, except in the case of fraud by such Holder.

  
 The indemnity and contribution agreements contained in this
Section 5 are in addition to any liability that the Indemnifying Parties may have to the Indemnified Parties. 
  
 6. Miscellaneous 
  
 (a) Remedies. In the event of a breach by the Company or by a Holder, of any of their obligations under this Agreement, each Holder or the Company,
as the case may be, in addition to being entitled to exercise all rights granted by law and under this Agreement, including recovery of damages, will be entitled to specific performance of its rights under this Agreement. The Company and each Holder
agree that monetary damages would not provide adequate compensation for any losses incurred by reason of a breach by it of any of the provisions of this Agreement and hereby further agrees that, in the event of any action for specific performance in
respect of such breach, it shall waive the defense that a remedy at law would be adequate. 
  
 (b) No Piggyback on Registrations. Except as set forth on Schedule 6(b) attached hereto, neither the Company nor any of its security holders (other than the Holders in such capacity pursuant hereto) may
include securities of the Company in the Registration Statement other than the Registrable Securities. The Company shall not file any other registration statements until the initial Registration Statement required hereunder is declared effective by
the Commission, provided that this Section 6(b) shall not prohibit the Company from filing amendments to registration statements already filed. 
  
 (c) Compliance. Each Holder covenants and agrees that it will comply with the prospectus delivery requirements of the Securities Act as applicable
to it in connection with sales of Registrable Securities pursuant to the Registration Statement. 
  
 (d) Discontinued Disposition. Each Holder agrees by its acquisition of such Registrable Securities that, upon receipt of a notice from the Company
of the occurrence of any event of the kind described in Section 3(d), such Holder will forthwith discontinue disposition of such Registrable Securities under a Registration Statement until such Holder’s receipt of the copies of the supplemented
Prospectus and/or amended Registration Statement, or until it is advised in writing (the “Advice”) by the Company that the use of the applicable Prospectus may be resumed, and, in either case, has received copies of any additional
or supplemental filings that are incorporated or deemed to be incorporated by reference in such Prospectus or Registration Statement. The Company shall use its reasonable best efforts to ensure that the use of the Prospectus may be resumed as
promptly as is practicable under the circumstances. The Company agrees and acknowledges that any periods during which the Holder is required to discontinue the disposition of the Registrable Securities hereunder shall be subject to the provisions of
Section 2(b). 
  

 11 








 (e) Piggy-Back Registrations. If at any time during the Effectiveness Period there is not an
effective Registration Statement covering all of the Registrable Securities and the Company shall determine to prepare and file with the Commission a registration statement relating to an offering for its own account or the account of others under
the Securities Act of any of its equity securities, other than on Form S-4 or Form S-8 (each as promulgated under the Securities Act) or their then equivalents relating to equity securities to be issued solely in connection with any acquisition of
any entity or business or equity securities issuable in connection with the stock option or other employee benefit plans, then the Company shall send to each Holder a written notice of such determination and, if within fifteen days after the date of
such notice, any such Holder shall so request in writing, the Company shall include in such registration statement all or any part of such Registrable Securities such holder requests to be registered; provided, that, the Company shall not be
required to register any Registrable Securities pursuant to this Section 6(e) that are eligible for resale pursuant to Rule 144(k) promulgated under the Securities Act or that are the subject of a then effective Registration Statement. 

 
 (f) Amendments and Waivers. The provisions of this Agreement,
including the provisions of this sentence, may not be amended, modified or supplemented, and waivers or consents to departures from the provisions hereof may not be given, unless the same shall be in writing and signed by the Company and the Holders
of 66.6% of the then outstanding Registrable Securities. Notwithstanding the foregoing, a waiver or consent to depart from the provisions hereof with respect to a matter that relates exclusively to the rights of Holders and that does not directly or
indirectly affect the rights of other Holders may be given by Holders of all of the Registrable Securities to which such waiver or consent relates; provided, however, that the provisions of this sentence may not be amended, modified,
or supplemented except in accordance with the provisions of the immediately preceding sentence. 
  
 (g) Notices. Any and all notices or other communications or deliveries required or permitted to be provided hereunder shall be delivered as set
forth in the Purchase Agreement. 
  
 (h) Successors and
Assigns. This Agreement shall inure to the benefit of and be binding upon the successors and permitted assigns of each of the parties and shall inure to the benefit of each Holder. The Company may not assign its rights or obligations hereunder
without the prior written consent of all of the Holders of the then-outstanding Registrable Securities. Each Holder may assign their respective rights hereunder in the manner and to the Persons as permitted under the Purchase Agreement. 

 
 (i) No Inconsistent Agreements. Neither the Company nor any of its
subsidiaries has entered, as of the date hereof, nor shall the Company or any of its subsidiaries, on or after the date of this Agreement, enter into any agreement with respect to its securities, that would have the effect of impairing the rights
granted to the Holders in this Agreement or otherwise conflicts with the provisions hereof. Except as set forth on Schedule 6(i), neither the Company nor any of its subsidiaries has previously entered into any agreement granting any
registration rights with respect to any of its securities to any Person that have not been satisfied in full. 
  

 12 








 (j) Execution and Counterparts. This Agreement may be executed in any number of counterparts, each
of which when so executed shall be deemed to be an original and, all of which taken together shall constitute one and the same Agreement. In the event that any signature is delivered by facsimile transmission, such signature shall create a valid
binding obligation of the party executing (or on whose behalf such signature is executed) the same with the same force and effect as if such facsimile signature were the original thereof. 
  
 (k) Governing Law. All questions concerning the construction, validity, enforcement and interpretation of this
Agreement shall be determined with the provisions of the Purchase Agreement. 
  
 (l) Cumulative Remedies. The remedies provided herein are cumulative and not exclusive of any remedies provided by law. 
  

(m) Severability. If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction to be invalid,
illegal, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions set forth herein shall remain in full force and effect and shall in no way be affected, impaired or invalidated, and the parties hereto shall use
their reasonable best efforts to find and employ an alternative means to achieve the same or substantially the same result as that contemplated by such term, provision, covenant or restriction. It is hereby stipulated and declared to be the
intention of the parties that they would have executed the remaining terms, provisions, covenants and restrictions without including any of such that may be hereafter declared invalid, illegal, void or unenforceable. 
  
 (n) Headings. The headings in this Agreement are for convenience of
reference only and shall not limit or otherwise affect the meaning hereof. 
  
 (o) Independent Nature of Holders’ Obligations and Rights. The obligations of each Holder hereunder are several and not joint with the obligations of any other Holder hereunder, and no Holder shall be
responsible in any way for the performance of the obligations of any other Holder hereunder. Nothing contained herein or in any other agreement or document delivered at any closing, and no action taken by any Holder pursuant hereto or thereto, shall
be deemed to constitute the Holders as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Holders are in any way acting in concert with respect to such obligations or the transactions
contemplated by this Agreement. Each Holder shall be entitled to protect and enforce its rights, including without limitation the rights arising out of this Agreement, and it shall not be necessary for any other Holder to be joined as an additional
party in any proceeding for such purpose.

 ANNEX A 
  
 Plan of Distribution 
  
 Each Selling Stockholder (the “Selling Stockholders”) of the common stock (“Common Stock”) of Cambridge Heart, Inc., a
Delaware corporation (the “Company”) and any of their pledgees, assignees and successors-in-interest may, from time to time, sell any or all of their shares of Common Stock on the Trading Market or any other stock exchange, market
or trading facility on which the shares are traded or in private transactions. These sales may be at fixed or negotiated prices. A Selling Stockholder may use any one or more of the following methods when selling shares: 
  

	 	•	ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers; 

  

	 	•	block trades in which the broker-dealer will attempt to sell the shares as agent but may position and resell a portion of the block as principal to facilitate the transaction;


  

	 	•	purchases by a broker-dealer as principal and resale by the broker-dealer for its account; 

  

	 	•	an exchange distribution in accordance with the rules of the applicable exchange; 

  

	 	•	privately negotiated transactions; 

  

	 	•	settlement of short sales entered into after the date of this prospectus; 

  

	 	•	broker-dealers may agree with the Selling Stockholders to sell a specified number of such shares at a stipulated price per share; 

  

	 	•	a combination of any such methods of sale; 

  

	 	•	through the writing or settlement of options or other hedging transactions, whether through an options exchange or otherwise; or 

  

	 	•	any other method permitted pursuant to applicable law. 

  
 The Selling Stockholders may also sell shares under Rule 144 under the Securities Act of 1933, as amended (the “Securities Act”), if
available, rather than under this prospectus. 
  
 Broker-dealers
engaged by the Selling Stockholders may arrange for other brokers-dealers to participate in sales. Broker-dealers may receive commissions or discounts from the Selling Stockholders (or, if any broker-dealer acts as agent for the purchaser of shares,
from the purchaser) in amounts to be negotiated. Each Selling Stockholder does not expect these commissions and discounts relating to its sales of shares to exceed what is customary in the types of transactions involved. 
  

 16 








 In connection with the sale of our common stock or interests therein, the Selling Stockholders may enter
into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the common stock in the course of hedging the positions they assume. The Selling Stockholders may also sell shares of our
common stock short and deliver these securities to close out their short positions, or loan or pledge the common stock to broker-dealers that in turn may sell these securities. The Selling Stockholders may also enter into option or other
transactions with broker-dealers or other financial institutions or the creation of one or more derivative securities which require the delivery to such broker-dealer or other financial institution of shares offered by this prospectus, which shares
such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction). 
  
 The Selling Stockholders and any broker-dealers or agents that are involved in selling the shares may be deemed to be “underwriters” within the
meaning of the Securities Act in connection with such sales. In such event, any commissions received by such broker-dealers or agents and any profit on the resale of the shares purchased by them may be deemed to be underwriting commissions or
discounts under the Securities Act. Each Selling Stockholder has informed the Company that it does not have any agreement or understanding, directly or indirectly, with any person to distribute the Common Stock. 
  
 The Company is required to pay certain fees and expenses incurred by the
Company incident to the registration of the shares. The Company has agreed to indemnify the Selling Stockholders against certain losses, claims, damages and liabilities, including liabilities under the Securities Act. 
  
 Because Selling Stockholders may be deemed to be “underwriters”
within the meaning of the Securities Act, they will be subject to the prospectus delivery requirements of the Securities Act. In addition, any securities covered by this prospectus which qualify for sale pursuant to Rule 144 under the Securities Act
may be sold under Rule 144 rather than under this prospectus. Each Selling Stockholder has advised us that they have not entered into any agreements, understandings or arrangements with any underwriter or broker-dealer regarding the sale of the
resale shares. There is no underwriter or coordinating broker acting in connection with the proposed sale of the resale shares by the Selling Stockholders. 
  
 We agreed to keep this prospectus effective until the earlier of (i) the date on which the shares may be resold by the Selling Stockholders without
registration and without regard to any volume limitations by reason of Rule 144(e) under the Securities Act or any other rule of similar effect or (ii) all of the shares have been sold pursuant to the prospectus or Rule 144 under the Securities Act
or any other rule of similar effect. The resale shares will be sold only through registered or licensed brokers or dealers if required under applicable state securities laws. In addition, in certain states, the resale shares may not be sold unless
they have been registered or qualified for sale in the applicable state or an exemption from the registration or qualification requirement is available and is complied with. 
  
 Under applicable rules and regulations under the Exchange Act, any person engaged in the distribution of the resale shares
may not simultaneously engage in market making activities with respect to our common stock for a period of two business days prior to the commencement 
  

 17 








 of the distribution. In addition, the Selling Stockholders will be subject to applicable provisions of the Exchange Act
and the rules and regulations thereunder, including Regulation M, which may limit the timing of purchases and sales of shares of our common stock by the Selling Stockholders or any other person. We will make copies of this prospectus available to
the Selling Stockholders and have informed them of the need to deliver a copy of this prospectus to each purchaser at or prior to the time of the sale.
