Statement under Section 3.1 hereof or any amendment or supplement thereto without the consent of the Holders; provided, however, that the Company at all times reserves the right to provide registration rights, pursuant to a
separate registration statement, to the holders of any securities of the Company. 
 4. Filings, Etc.

commercially reasonable efforts to have the Registration Statement declared effective as soon as practicable, and in any event no later than ninety (90) calendar days following the Closing Date. The Company shall notify the Holders by facsimile
or e-mail (as provided by Holders) as promptly as practicable, and in any event, within twenty-four (24) hours, after the Registration Statement is declared effective and shall simultaneously provide the Holders with copies of any related
prospectus to be used in connection with the sale or other disposition of the securities covered thereby. 
 5. Obligations of the Company.
In connection with the Company’s obligation under Sections 3 and 4 hereof to file the Registration Statement with the SEC and to use commercially reasonable efforts to cause the Registration Statement to become effective as
soon as practicable, the Company shall, as expeditiously as reasonably possible: 
 5.1. Prepare and file with the SEC such
amendments and supplements to the Registration Statement and the prospectus used in connection therewith as may be necessary to comply with the provisions of the Securities Act with respect to the disposition of all Registrable Shares covered by the
Registration Statement; 

  
 3 








 5.2. Furnish to the Holders such number of copies of a prospectus, including a preliminary
prospectus, in conformity with the requirements of the Securities Act, and such other documents (including, without limitation, prospectus amendments and supplements as are prepared by the Company in accordance with Section 5.1 above) as
the Holders may reasonably request in order to facilitate the disposition of such Holders’ Registrable Shares; 
 5.3.
Notify the Holders, at any time when a prospectus relating to the Registration Statement is required to be delivered under the Securities Act, of the happening of any event as a result of which the prospectus included in or relating to the
Registration Statement contains an untrue statement of a material fact or omits any fact necessary to make the statements therein not misleading; and, thereafter, the Company will promptly prepare (and, when completed, give notice to each Holder) a
supplement or amendment to such prospectus so that, as thereafter delivered to the purchasers of such Registrable Shares, such prospectus will not contain an untrue statement of a material fact or omit to state any fact necessary to make the
statements therein not misleading; upon such notification by the Company, the Holders will not offer or sell Registrable Shares until the Company has notified the Holders that it has prepared a supplement or amendment to such prospectus and
delivered copies of such supplement or amendment to the Holders (it being understood and agreed by the Company that the foregoing clause shall in no way diminish or otherwise impair the Company’s obligation to promptly prepare a prospectus
amendment or supplement as above provided in this Section 5.3 and deliver copies of same as above provided in Section 5.2 hereof); 
 5.4. Promptly respond to any and all comments received from the SEC, with a view towards causing the Registration Statement or any amendment thereto to be declared effective by the SEC as soon as
practicable, and file an acceleration request as soon as practicable, but no later than five (5) business days, following the resolution or clearance of all SEC comments or, if applicable, notification by the SEC that any such Registration
Statement or any amendment thereto will not be subject to review; 
 5.5. Use commercially reasonable efforts to register and
qualify the Registrable Shares covered by the Registration Statement under such other securities or Blue Sky laws of such states where such registration and/or qualification is required as shall be reasonably requested by a Holder, provided that the
Company shall not be required in connection therewith or as a condition thereto to qualify to do business or to file a general consent to service of process in any such states or jurisdictions, and provided further that (notwithstanding anything in
this Agreement to the contrary with respect to the bearing of expenses) if any jurisdiction in which any of such Registrable Shares shall be qualified shall require that expenses incurred in connection with the qualification therein of any such
Registrable Shares be borne by the Holders, then the Holders shall, to the extent required by such jurisdiction, pay their pro rata share of such qualification expenses; 
 5.6. Subject to the terms and conditions of this Agreement, use commercially reasonable efforts to (i) prevent the issuance of any stop order or other suspension of effectiveness of a Registration
Statement, or the suspension of the qualification of any of the 

  
 4 








 
Registrable Shares for sale in any jurisdiction in the United States, and (ii) if such an order or suspension is issued, obtain the withdrawal of such order or suspension at the earliest
practicable moment and notify each holder of Registrable Shares of the issuance of such order and the resolution thereof or its receipt of notice of the initiation or threat of any proceeding such purpose; 

5.7. Permit a single firm of counsel designated by the Holders to review the Registration Statement and all amendments and supplements
thereto (as well as all requests for acceleration or effectiveness thereof), at Holders’ own cost, a reasonable period of time prior to their filing with the SEC (not less than five (5) business days) and use commercially reasonable
efforts to reflect in such documents any comments as such counsel may reasonably propose (so long as such comments are provided to the Company at least (2) business days prior to the expected filing date) and will not request acceleration of
such Registration Statement without prior notice to such counsel; 
 5.8. Use commercially reasonable efforts to cause all the
Registrable Shares covered by the Registration Statement to be listed on the NASDAQ National Market, or such other securities exchange on which the Company’s common stock is then listed; and 

5.9. Comply with all requirements of the Financial Industry Regulatory Authority, Inc. with regard to the issuance of the Registrable
Shares and the listing thereof on the NASDAQ National Market, and engage a transfer agent and registrar to maintain the Company’s stock ledger for all Registrable Shares covered by the Registration Statement not later than the effective date of
the Registration Statement. 
 6. Furnish Information. It shall be a condition precedent to the obligations of the Company to take any
action pursuant to this Agreement that the Holders shall furnish to the Company such information regarding them and the securities held by them as the Company shall reasonably request and as shall be required in order to effect any registration by
the Company pursuant to this Agreement. Each Holder shall promptly notify the Company of any changes in the information furnished to the Company. 
 7. Expenses of Registration. All expenses incurred by the Company in connection with the registration of the Registrable Shares pursuant to this Agreement, including, without limitation, all
registration and qualification and filing fees, printing, and fees and disbursements of counsel for the Company, shall be borne by the Company. Any expenses incurred by a Holder, including, without limitation, fees and disbursements of counsel for
such Holder or any brokerage and other selling commissions and discounts shall be borne by such Holder. 
 8. Delay of Registration. The
Holders shall not take any action to restrain, enjoin or otherwise delay any registration as the result of any controversy which might arise with respect to the interpretation or implementation of this Agreement. In the event such a delay occurs,
the dates by which the Registration Statement is required to be filed and become effective pursuant to this Agreement shall be extended by the same number of days of such delay. 

  
 5 








 9. Indemnification. 
 9.1. The Company will indemnify and hold harmless each Holder and each person who controls each Holder within the meaning of the Securities Act or the Exchange Act, if any (in each case, a “Holder
Indemnified Person”) against any loss, claim, damage or liability (“Loss”), to which such Holder Indemnified Person may become subject under the Securities Act or otherwise, insofar as such Loss arises out of or is based
upon (i) any untrue or alleged untrue statement of any material fact contained in the Registration Statement, in any preliminary prospectus or final prospectus relating thereto or in any amendments or supplements to the Registration Statement
or any such preliminary prospectus or final prospectus, or (ii) the omission or alleged omission to state therein a material fact required to be stated therein, or necessary to make the statements therein not misleading; provided,
however, that the indemnity agreement contained in this Section 9.1 shall not apply to amounts paid in settlement of any such Loss if such settlement is effected without the consent of the Company, nor shall the Company be liable
in any such case for any such Loss to the extent that it arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in connection with the Registration Statement, any preliminary prospectus or
final prospectus relating thereto or any amendments or supplements to the Registration Statement or any such preliminary prospectus or final prospectus, in reliance upon and in conformity with written information furnished expressly for use in
connection with the Registration Statement or any such preliminary prospectus or final prospectus by a Holder, any underwriter for such Holder or controlling person with respect to such Holder, or any breach by any Holder of this Agreement or the
Asset Purchase Agreement, related to the failure of such Holder to comply with the covenants and agreements contained in this Agreement or the Asset Purchase Agreement respecting sales of the Preferred Shares. 

9.2. Each Holder will severally and not jointly indemnify and hold harmless the Company, each of its directors, each of its officers who
have signed the Registration Statement, each person, if any, who controls the Company within the meaning of the Securities Act, and all other Holders against any Loss to which the Company or any such director, officer, controlling person, or such
other Holder may become subject to, under the Securities Act or otherwise, insofar as such Loss arises out of or is based upon any untrue or alleged untrue statement of any material fact contained in the Registration Statement or any preliminary
prospectus or final prospectus, relating thereto or in any amendments or supplements to the Registration Statement or any such preliminary prospectus or final prospectus, or arises out of or is based upon the omission or alleged omission to state
therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent and only to the extent that such untrue statement or alleged untrue statement or omission or alleged
omission was made in the Registration Statement, in any preliminary prospectus or final prospectus relating thereto or in any amendments or supplements to the Registration Statement or any such preliminary prospectus or final prospectus, in reliance
upon and in conformity with written information furnished by the Holder expressly for use in connection with the Registration Statement, or any preliminary prospectus or final prospectus; and provided, further, however, that the
indemnity agreement contained in this Section 9.2 shall not apply to amounts paid in settlement of any such Loss if such settlement is effected without the consent of those Holder(s) against which the request for indemnity is being made.

 9.3. Promptly after receipt by an indemnified party under this Section 9 of notice of the commencement of any
action, such indemnified party will, if a claim in respect thereof is to 

  
 6 








 
be made against any indemnifying party under this Section 9, notify the indemnifying party in writing of the commencement thereof and the indemnifying party shall have the right to
participate in and, to the extent the indemnifying party desires, jointly with any other indemnifying party similarly noticed, to assume at its expense the defense thereof with counsel mutually satisfactory to the indemnifying parties and the
indemnified parties. In the event that the indemnifying party assumes any such defense, the indemnified party may participate in such defense with its own counsel and at its own expense, provided, however, that the counsel for the
indemnifying party shall act as lead counsel in all matters pertaining to such defense or settlement of such claim. The failure to notify an indemnifying party promptly of the commencement of any such action shall not relieve such indemnifying party
of any liability to the indemnified party under this Section 9, except to the extent the indemnifying party is actually prejudiced in its ability to defend such action. 

9.4. If the indemnification provided for in this Section 9 is held by a court of competent jurisdiction to be unavailable to
an indemnified party with respect to any Loss referred to therein, then the indemnifying party, in lieu of indemnifying such indemnified party hereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such
Loss in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and of the indemnified party on the other in connection with the statements or omissions that resulted in such Loss as well as any
other relevant equitable considerations. The relative fault of the indemnifying party and of the indemnified party shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the
omission to state a material fact relates to information supplied by the indemnifying party or by the indemnified party and the parties’ relative intent, knowledge, access to information, and opportunity to correct or prevent such statement or
omission. 
 10. Reports Under The Exchange Act. With a view to making available to the Holders the benefits of Rule 144 and any other
rule or regulation of the SEC that may at any time permit the Holders to sell the Preferred Shares to the public without registration until the Mandatory Registration Termination Date, the Company agrees to use commercially reasonable efforts:
(i) to make and keep public information available as those terms are understood in Rule 144, (ii) to file with the SEC in a timely manner all reports and other documents required to be filed by an issuer of securities registered under the
Securities Act or the Exchange Act, (iii) as long as any Holder owns any Preferred Shares, to furnish in writing upon such Holder’s request a written statement by the Company that it has complied with the reporting requirements of Rule 144
and of the Securities Act and the Exchange Act, and (iv) undertake any additional actions reasonably necessary to maintain the availability of the Registration Statement or the use of Rule 144. 

11. Suspension. Notwithstanding anything in this Agreement to the contrary, if the Company shall furnish to the Holders a certificate signed by
the President or Chief Executive Officer of the Company stating that the Board has made the good faith determination (i) that continued use by the Holders of the Registration Statement for purposes of effecting offers or sales of Registrable
Shares pursuant thereto would require, under the Securities Act, premature disclosure in the Registration Statement (or the prospectus relating thereto) of material, nonpublic information concerning the Company, its business or prospects or any
proposed material transaction involving the Company, (ii) that such premature disclosure would be materially adverse to the Company, its business or prospects or any such proposed material


  
 7 








 
transaction or would make the successful consummation by the Company of any such material transaction significantly less likely and (iii) that it is therefore essential to suspend the use by
the Holders of such Registration Statement (and the prospectus relating thereto) for purposes of effecting offers or sales of Registrable Shares pursuant thereto, then the right of the Holders to use the Registration Statement (and the prospectus
relating thereto) for purposes of effecting offers or sales of Registrable Shares pursuant thereto shall be suspended for a period (the “Suspension Period”) of not more than forty-five (45) days after delivery by the Company of
the certificate referred to above in this Section 11; provided that the Company shall be entitled to no more than two (2) such Suspension Periods during any twelve (12) month period. During the Suspension Period, none of the
Holders shall offer or sell any Registrable Shares pursuant to or in reliance upon the Registration Statement (or the prospectus relating thereto). The Company shall use commercially reasonable efforts to terminate any Suspension Period as promptly
as practicable. 
 12. Transfer of Registration Rights. None of the rights of any Holder under this Agreement shall be transferred or
assigned to any person unless (i) such person is a Qualifying Holder (as defined below), and (ii) such person agrees to become a party to, and bound by, all of the terms and conditions of, this Agreement by duly executing and delivering to
the Company an Instrument of Adherence in the form attached as Exhibit A hereto. For purposes of this Section 12, the term “Qualifying Holder” shall mean, with respect to any Holder, (a) any corporation,
partnership controlling, controlled by, or under common control with, such Holder or any partner thereof, or (b) any other direct transferee from such Holder of at least 25% of those Registrable Shares held by such Holder. None of the rights of
any Holder under this Agreement shall be transferred or assigned to any Person (including, without limitation, a Qualifying Holder) that acquires Registrable Shares in the event that and to the extent that such Person is eligible to immediately
resell such Registrable Shares pursuant to Rule 144(b)(1) of the Securities Act or any other exemption from the registration provisions of the Securities Act. After any transfer in accordance with this Section 12, the rights and
obligations of a Holder as to any transferred Registrable Shares shall be the rights and obligations of the Holder Permitted Transferee holding such Registrable Shares. 
 13. Confidentiality of Records. Each Holder agrees not to disclose any material non-public information provided by the Company in connection with a registration (including, without limitation, the
contemplated filing and timing of filing of a Registration Statement). 
 14. Entire Agreement. This Agreement constitutes and contains
the entire agreement and understanding of the parties with respect to the subject matter hereof, and it also supersedes any and all prior negotiations, correspondence, agreements or understandings with respect to the subject matter hereof.

 15. Miscellaneous. 
 15.1. This Agreement may not be amended, modified or terminated, and no rights or provisions may be waived, except with the written consent of the Majority Holders and the Company. 

15.2. This Agreement shall be governed by and construed and enforced in accordance with the laws of the State of New York, and shall be
binding upon and inure to the benefit of the parties hereto and their respective heirs, personal representatives, successors or assigns, provided that the terms and conditions of Section 12 hereof are satisfied. 

  
 8 








 15.3. This Agreement shall be binding upon and inure to the benefit of any transferee of any
of the Preferred Shares provided that the terms and conditions of Section 12 hereof are satisfied. Notwithstanding anything in this Agreement to the contrary, if at any time any Holder shall cease to own any Preferred Shares, all of such
Holder’s rights under this Agreement shall immediately terminate. 
 15.4. All notices and communications hereunder shall
be deemed to have been duly given and made if in writing and if served by personal delivery upon the party for whom it is intended or delivered by registered or certified mail, return receipt requested, or if sent by facsimile or email, provided
