Registration. 
 (a) Mandatory Registration. Not later than the Registration Filing Date, the Company shall file with the
Commission a Registration Statement on Form S-1, Form S-3 or any other appropriate form, relating to the resale by the Holders of all of the Registrable Securities, and
the Company shall use commercially reasonable efforts to cause such Registration Statement to be declared effective by the Commission as soon as practicable thereafter, but in no event later than the Effectiveness Deadline and shall use its best
efforts to keep such Registration Statement continuously effective under the Securities Act until the date that all Registrable Securities covered by such Registration Statement (i) have been sold thereunder, or (ii) may be sold without
volume or manner-of-sale restrictions pursuant to Rule 144 and without the requirement for the Company to be in compliance with the current public information
requirement under Rule 144, 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 registration rights under this Section 2 shall not apply or be

 (b) Allocation of Registrable Securities. The initial number of Registrable Securities included
in any Registration Statement and any increase in the number of Registrable Securities included therein shall be allocated pro rata among the Holders based on the number of Registrable Securities held by each Holder at the time the Registration
Statement covering such initial number of Registrable Securities or increase thereof is declared effective by the SEC. In the event that a Holder sells or otherwise transfers any of such Holder’s Registrable Securities, each transferee shall be
allocated a pro rata portion of the then remaining number of Registrable Securities included in such Registration Statement for such transferor. Any shares of Common Stock included in a Registration Statement and which remain allocated to any Person
which ceases to hold any Registrable Securities covered by such Registration Statement shall be allocated to the remaining Holders, pro rata based on the number of Registrable Securities then held by such Holders which are covered by such
Registration Statement. In no event shall the Company include any securities other than Registrable Securities in any Registration Statement without the prior written consent of the Majority Holders. 

(c) (1) if the Commission allows the Registration Statement to be declared effective at any time before or after the Effectiveness Date,
subject to the withdrawal of certain Registrable Securities from the Registration Statement, and the reason is the Commission’s determination that (x) the offering of any of the Registrable Securities constitutes a primary offering of
securities by the Company, (y) Rule 415 may not be relied upon for the registration of the resale of any or all of the Registrable Securities, and/or (z) a Holder of any Registrable Securities must be named as an underwriter, the Holders
understand and agree, unless otherwise directed in writing by the Majority Holders, the number of Registrable Securities to be registered on such Registration Statement will first be reduced by the Registrable Securities represented by the Dividend
Shares and second to the Registrable Securities represented by Conversion Shares (applied, in either case, to the Holders on a pro rata basis based on the total number of unregistered Dividend Shares and Conversion Shares held by such Holders). In
addition, any such affected Holder shall be entitled to Piggyback Registration rights after the Registration Statement is declared effective by the Commission until such time as: (AA) all Registrable Securities have been registered pursuant to an
effective Registration Statement, (BB) the Registrable Securities may be resold without restriction pursuant to SEC Rule 144 of the Securities Act or (CC) the Holder agrees to be named as an underwriter in any such registration statement. The
Holders acknowledge and agree the provisions of this paragraph may apply to more than one Registration Statement; and 
 (2) For not more
than thirty (30) consecutive days or for a total of not more than sixty (60) days in any twelve (12) month period, the Company may suspend the use of any prospectus included in any Registration Statement contemplated by this Section
in the event that the Company determines in good faith that such suspension is necessary to (A) delay the disclosure of MNPI concerning the Company, the disclosure of which at the time is not, in the good faith opinion of the Company, in the
best interests of the Company or (B) amend or supplement the affected Registration Statement or the related prospectus so that (i) such Registration Statement shall not 

  
 4 













 
include 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 or (ii) such prospectus shall not
include an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements, in the light of the circumstances under which they were made, not misleading, including in connection with the filing of a
post-effective amendment to such Registration Statement in connection with the Company’s filing of an Annual Report on Form 10-K for any fiscal year (an “Allowed Delay”); provided, that
the Company shall promptly (a) notify each Holder in writing of the commencement of an Allowed Delay, but shall not (without the prior written consent of an Holder) disclose to such Holder any MNPI giving rise to an Allowed Delay,
(b) advise the Holders in writing to cease all sales under the Registration Statement until the end of the Allowed Delay and (c) use commercially reasonable efforts to terminate an Allowed Delay as promptly as practicable. 

(d) Piggyback Registration Rights. In addition to the Company’s agreement pursuant to Section 2(a) above, if the Company
shall, at any time during the Effectiveness Period or as contemplated pursuant to Section 2(c) and ending when all Registrable Securities have been sold by Holders, determine (i) to register for sale any of its Common Stock in an
underwritten offering, or (ii) to file a registration statement covering the resale of any shares of the Common Stock held by any of its shareholders (other than the registration contemplated in Section 2(a) above), the Company shall
provide written notice to the Holders, which notice shall be provided no less than fifteen (15) calendar days prior to the filing of such applicable registration statement (the “Company Notice”). In that event, the right of any
Holder to include the Registrable Securities in such a registration shall be conditioned upon such Holder’s written request to participate which shall be delivered to the Company within ten (10) calendar days after the Company Notice, as
well as such Holder’s participation in such underwriting (if applicable, for purposes of this paragraph) and the inclusion of such Holder’s Registrable Securities in the underwriting to the extent provided herein. All Holders proposing to
sell any of their Registrable Securities through such underwriting shall (together with the Company and any other stockholders of the Company selling their securities through such underwriting) enter into an underwriting agreement in customary form
with the underwriter selected for such underwriting. Notwithstanding anything herein to the contrary, if the underwriter determines that marketing factors require a limitation on the number of shares of Common Stock or the amount of other securities
to be underwritten, the underwriter may exclude some or all Registrable Securities from such registration and underwriting. The Company shall so advise all Holders (except those Holders who failed to timely elect to include their Registrable
Securities through such underwriting or have indicated to the Company their decision not to do so), and indicate to each such Holder the number of shares of Registrable Securities that may be included in the registration and underwriting, if any.
The number of Registrable Securities to be included in such registration and underwriting shall be allocated first to the Company, then to all other selling stockholders, including the Holders, who have requested to sell in the registration on a pro
rata basis according to the number of shares requested to be included therein. If any Holder disapproves of the terms of any such underwriting, such Holder may elect to withdraw such Holder’s Registrable Securities therefrom by delivering a
written notice to the Company and the underwriter. A Holder with Registrable Securities included in any registration shall furnish to the Company such information regarding itself, the Registrable Securities held by it, and the intended method of
disposition of such securities as shall be required in order to comply with any applicable law or regulation in connection with the registration of such Holder’s Registrable Securities or any qualification or compliance with respect


  
 5 













 
to such Holder’s Registrable Securities and referred to in this Agreement. The Company shall have the right to terminate or withdraw any registration initiated by it before the effective
date of such registration, whether or not any Holder has elected to include Registrable Securities in such registration. Notwithstanding the foregoing, the Company shall not be required to register any Registrable Securities pursuant to this
Section 2(d) that are eligible for resale pursuant to Rule 144 without restriction (including, without limitation, volume restrictions) or that are the subject of a then-effective Registration Statement. The Company may postpone or withdraw the
filing or the effectiveness of a piggyback registration at any time in its sole discretion. 
 3. Registration Procedures for Registrable
Securities. The Company will keep each Holder reasonably advised as to the filing and effectiveness of the Registration Statement. At its expense with respect to the Registration Statement, the Company will: 

(a) prepare and file with the Commission with respect to the Registrable Securities, a Registration Statement on Form S-1, Form S-3, or any other form for which the Company then qualifies or which counsel for the Company shall deem appropriate and which form shall be available for the sale of
the Registrable Securities in accordance with the intended methods of distribution thereof, and use its commercially reasonable efforts to cause such Registration Statement to become effective and shall remain effective during the
Effectiveness Period. Thereafter, the Company shall be entitled to withdraw such Registration Statement and the Holders shall have no further right to offer or sell any of the Registrable Securities registered for resale thereon pursuant to the
respective Registration Statement (or any prospectus relating thereto); 
 (b) if the Registration Statement is subject to review by the
Commission, respond in a commercially reasonable manner to all comments and diligently pursue resolution of any comments to the satisfaction of the Commission; 

(c) prepare and file with the Commission such amendments and supplements to such Registration Statement as may be necessary to keep such
Registration Statement effective during the Effectiveness Period; 
 (d) furnish, without charge, to each Holder of Registrable Securities
covered by such Registration Statement (i) a reasonable number of copies of such Registration Statement (including any exhibits thereto other than exhibits incorporated by reference), each amendment and supplement thereto as such Holder may
reasonably request, (ii) such number of copies of the prospectus included in such Registration Statement (including each preliminary prospectus and any other prospectus filed under Rule 424 of the Securities Act) as such Holders may reasonably
request, in conformity with the requirements of the Securities Act, and (iii) such other documents as such Holder may require to consummate the disposition of the Registrable Securities owned by such Holder, but only during the Effectiveness
Period; 
 (e) use its commercially reasonable efforts to register or qualify such registration under such other applicable securities laws
of such jurisdictions as any Holder of Registrable Securities covered by such Registration Statement reasonably requests and as may be necessary for the marketability of the Registrable Securities (such request to be made by the time the applicable
Registration Statement is deemed effective by the Commission) and do any and all other acts and things necessary to enable such Holder to consummate the disposition in such 

  
 6 













 
jurisdictions of the Registrable Securities owned by such Holder; provided, that the Company shall not be required to (i) qualify generally to do business in any jurisdiction where it
would not otherwise be required to qualify but for this paragraph, (ii) subject itself to taxation in any such jurisdiction, or (iii) consent to general service of process in any such jurisdiction. 

(f) notify each Holder of Registrable Securities, the disposition of which requires delivery of a prospectus relating thereto under the
Securities Act, of the happening of any event (as promptly as practicable after becoming aware of such event), which comes to the Company’s attention, that will after the occurrence of such event cause the prospectus included in such
Registration Statement, if not amended or supplemented, to contain an untrue statement of a material fact or an omission to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they
were made, not misleading, and the Company shall promptly thereafter prepare and furnish to such Holder a supplement or amendment to such prospectus (or prepare and file appropriate reports under the Exchange Act) so that, as thereafter delivered to
the purchasers of such Registrable Securities, such prospectus shall not contain an untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under
which they were made, not misleading, unless suspension of the use of such prospectus otherwise is authorized herein or in the event of a Blackout Period, in which case no supplement or amendment need be furnished (or Exchange Act filing made) until
the termination of such suspension or Blackout Period; 
 (g) comply, and continue to comply during the Effectiveness Period, in all
material respects with the Securities Act and the Exchange Act and with all applicable rules and regulations of the Commission with respect to the disposition of all securities covered by such Registration Statement; 

(h) as promptly as practicable after becoming aware of such event, notify each Holder of Registrable Securities being offered or sold pursuant
to the Registration Statement of the issuance by the Commission of any stop order or other suspension of effectiveness of the Registration Statement; 

(i) use its commercially reasonable efforts to cause all the Registrable Securities covered by the Registration Statement to be quoted on such
Approved Market on which securities of the same class or series issued by the Company are then listed or quoted; 
 (j) provide a transfer
agent and registrar, which may be a single entity, for the shares of Common Stock registered hereunder; 
 (k) though the Registrable
Securities will be issued in book entry form, 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
the Registration Statement, which certificates shall be free, to the extent permitted by applicable law, 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; and 
 (l) take all other reasonable actions necessary to expedite and facilitate the disposition by the Holders of the
Registrable Securities pursuant to the Registration Statement.

 4. Suspension of Offers and Sales. Each Holder agrees that, upon receipt of any
notice from the Company of the happening of any event of the kind described in Section 3(f) hereof or of the commencement of a Blackout Period, such Holder shall discontinue the disposition of Registrable Securities included in the Registration
Statement until such Holder’s receipt of the copies of the supplemented or amended prospectus contemplated by Section 3(f) hereof or notice of the end of the Blackout Period, and, if so directed by the Company, such Holder shall deliver to
the Company (at the Company’s expense) all copies (including, without limitation, any and all drafts), other than permanent file copies, then in such Holder’s possession, of the prospectus covering such Registrable Securities current at
the time of receipt of such notice. 
 5. Registration Expenses. The Company shall pay all expenses in connection with any
registration obligation provided herein, including, without limitation, all registration, filing, stock exchange fees, printing expenses, all fees and expenses of complying with applicable securities laws, and the fees and disbursements of counsel
for the Company and of its independent accountants; provided, that, in any registration, each party shall pay for its own underwriting discounts and commissions and transfer taxes. Except as provided in this Section 5 and Section 8,
the Company shall not be responsible for the expenses of any attorney or other advisor employed by a Holder. 
 6. Assignment of
Rights. The rights under this Agreement shall be automatically assignable by the Holders to any transferee of all or any portion of such Holder’s Registrable Securities if: (i) the Holder agrees in writing with the transferee or
assignee to assign such rights, and a copy of such agreement is furnished to the Company within a reasonable time after such assignment; (ii) the Company is, within a reasonable time after such transfer or assignment, furnished with written
notice of (a) the name and address of such transferee or assignee, and (b) the securities with respect to which such registration rights are being transferred or assigned and (iii) immediately following such transfer or assignment the
further disposition of such securities by the transferee or assignee is restricted under the Securities Act and applicable state securities laws; (iv) at or before the time the Company receives the written notice contemplated by clause
(ii) of this sentence the transferee or assignee agrees in writing with the Company to be bound by all of the provisions contained herein. 

7. Information by Holder. A Holder with Registrable Securities included in any registration shall furnish to the Company (and any
managing underwriter(s), where applicable) such information regarding itself, the Registrable Securities held by it, the intended method of disposition of such securities, and such other information as shall be required in order to comply with any
applicable law or regulation in connection with the registration of such Holder’s Registrable Securities or any qualification or compliance with respect to such Holder’s Registrable Securities and referred to in this Agreement. A form of
Selling Stockholder Questionnaire is attached as Exhibit A hereto. 
 8. Indemnification. 

(a) In the event of the offer and sale of Registrable Securities under the Securities Act, the Company shall, and hereby does, indemnify and
hold harmless, to the fullest extent permitted by law, each Holder, its directors, officers, partners, each other person who participates as an underwriter in the offering or sale of such securities, and each other person, if


  
 8 













 
any, who controls or is under common control with such Holder or any such underwriter within the meaning of Section 15 of the Securities Act, against any losses, claims, damages or
liabilities, joint or several, and expenses to which the Holder or any such director, officer, partner or underwriter or controlling person may become subject under the Securities Act, the Exchange Act, or any other federal or state law, insofar as
such losses, claims, damages, liabilities or expenses (or actions or proceedings, whether commenced or threatened, in respect thereof) arise out of or are based upon (1), in the case of any registration statement prepared and filed by the Company
under which Registrable Securities were registered under the Securities Act, if such registration statement contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the
statements therein not misleading or (2) in the case of any preliminary prospectus, final prospectus or summary prospectus contained in such registration statement, or any amendment or supplement thereto, if such preliminary prospectus, final
prospectus or summary prospectus includes an untrue statement of a material fact or omits to state a material fact necessary in order to make the statements, in the light of the circumstances under which they were made, not misleading, or any
violation or alleged violation of the Securities Act, the Exchange Act, any state securities law or any rule or regulation promulgated under the Securities Act, the Exchange Act or any state securities law in connection with this Agreement; and the
Company shall reimburse the Holder, and each such director, officer, partner, underwriter and controlling person for any legal or any other expenses reasonably incurred by them in connection with investigating, defending or settling any such loss,
claim, damage, liability, action or proceeding; provided, that such indemnity agreement found in this Section 8(a) shall in no event exceed the net proceeds from the Offering received by the Company; and provided further, that the
Company shall not be liable in any such case (i) to the extent that any such loss, claim, damage, liability (or action or proceeding in respect thereof) or expense arises out of or is based upon an untrue statement in or omission from such
registration statement, any such preliminary prospectus, final prospectus, summary prospectus, amendment or supplement in reliance upon and in conformity with written information furnished to the Company by the Holder specifically for use in the
preparation thereof or (ii) if the person asserting any such loss, claim, damage, liability (or action or proceeding in respect thereof) who purchased the Registrable Securities that are the subject thereof did not receive a copy of the
preliminary prospectus or the final prospectus (or the final prospectus as amended or supplemented) at or prior to the written confirmation of the sale of such Registrable Securities to such person because of the failure of such Holder or
underwriter to so provide such preliminary or final prospectus and the untrue statement or omission of a material fact made in such preliminary prospectus was corrected in the amended preliminary or final prospectus (or the final prospectus as
amended or supplemented). Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of the Holders, or any such director, officer, partner, underwriter or controlling person and shall survive the
transfer of such shares by the Holder. 
 (b) As a condition to including Registrable Securities in any registration statement filed
pursuant to this Agreement, each Holder agrees to be bound by the terms of this Section 8 and to indemnify and hold harmless, to the fullest extent permitted by law, the Company, its directors and officers, and each other person, if any, who
controls the Company within the meaning of Section 15 of the Securities Act, against any losses, claims, damages or liabilities, joint or several, to which the Company or any such director or officer or controlling person may become subject
under the Securities Act, the Exchange Act, or any other federal or state law, to the extent arising out of or based solely upon: (x) such Holder’s failure to comply with the prospectus 

  
 9 













 
delivery requirements of the Securities Act or (y)(1), in the case of any registration statement prepared and filed by the Company under which Registrable Securities were registered under the
Securities Act, if such registration statement contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading or (2) in the case of
any preliminary prospectus, final prospectus or summary prospectus contained in such registration statement, or any amendment or supplement thereto, such preliminary prospectus, final prospectus or summary prospectus includes an untrue statement of
a material fact or omits to state a material fact necessary in order to make the statements, in the light of the circumstances under which they were made, not misleading, (i) to the extent, but only to the extent, that such untrue statement or
omission referred to in (y)(1) or (y)(2) above is contained in any information so furnished in writing by such Holder to the Company specifically for inclusion in the registration statement or such prospectus or (ii) to the extent that
(1) such untrue statements or omissions referred to in (y)(1) or (y)(2) above 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, 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(f) hereof, 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 3(f). Each Holder’s obligation to indemnify shall be individual, not joint and
several, and 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) Promptly after receipt by an indemnified party of notice of the commencement of any action or proceeding involving a
claim referred to in this Section (including any governmental action), such indemnified party shall, if a claim in respect thereof is to be made against an indemnifying party, give written notice to the indemnifying party of the commencement of such
action; provided, that the failure of any indemnified party to give notice as provided herein shall not relieve the indemnifying party of its obligations under this Section, except to the extent that the indemnifying party is actually
prejudiced by such failure to give notice. In case any such action is brought against an indemnified party, the indemnifying party shall be entitled to participate in and to assume the defense thereof, with counsel reasonably satisfactory to such
indemnified party and, after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party for any legal or other expenses
subsequently incurred by the indemnified party in connection with the defense thereof, unless in such indemnified party’s reasonable judgment a conflict of interest between such indemnified and indemnifying parties arises in respect of such
claim after the assumption of the defenses thereof or the indemnifying party fails to defend such claim in a diligent manner. If, in such indemnified party’s reasonable judgment a conflict of interest between such indemnified and indemnifying
parties arises in respect of such claim after the assumption of the defenses thereof, the indemnified party (together with all other indemnified parties that may be represented without conflict by one counsel) shall have the right to retain one
separate counsel, with the reasonable fees and expenses to be paid by the indemnifying party. No indemnifying party shall be liable for any settlement of any action or proceeding effected without 

  
 10 













 
its consent. No indemnifying party shall, without the consent of the indemnified party (which consent shall not be unreasonably withheld, conditioned or delayed), consent to entry of any judgment
or enter into any settlement, unless such consent to entry of judgment or settlement includes as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect of such claim
or litigation. Notwithstanding anything to the contrary set forth herein, and without limiting any of the rights set forth above, in any event any party shall have the right to retain, at its own expense, counsel with respect to the defense of a
claim. 
 (d) If an indemnifying party does or is not permitted to assume the defense of an action pursuant to Section 8(c) or in the
case of the expense reimbursement obligation set forth in Sections 8(a) and (b), the indemnification required by Sections 8(a) and 8(b) shall be made by periodic payments of the amount thereof during the course of the investigation or defense, as
and when bills received or expenses, losses, damages, or liabilities are incurred provided that the indemnifying party is provided appropriate documentation. 

(e) If the indemnification provided for in Section 8(a) or 8(b) is held by a court of competent jurisdiction to be unavailable to an
indemnified party with respect to any loss, liability, claim, damage or expense referred to herein, the indemnifying party, in lieu of indemnifying such indemnified party hereunder, shall (i) contribute to the amount paid or payable by such
indemnified party as a result of such loss, liability, claim, damage or expense as is appropriate to reflect the proportionate relative fault of the indemnifying party on the one hand and the indemnified party on the other (determined by reference
to, among other things, whether the untrue or alleged untrue statement of a material fact or omission relates to information supplied by the indemnifying party or the indemnified party and the parties’ relative intent, knowledge, access to

several and not joint with the obligations of any other Purchaser, and each Purchaser shall not be responsible in any way for the performance of the obligations of any other Purchaser under this Agreement. Nothing contained herein and no action
taken by any Purchaser pursuant hereto, shall be deemed to constitute such Purchasers as a partnership, an association, a joint venture, or any other kind of entity, or create a presumption that the Purchasers are in any way acting in concert or as
a group with respect to such obligations or the transactions contemplated by this Agreement. Each Purchaser shall be entitled to independently protect and enforce its rights, including without limitation the rights arising out of this Agreement, and
it shall not be necessary for any other Purchaser to be joined as an additional party in any proceeding for such purpose.

application of the laws of any jurisdictions other than the State of New York. Each party hereby irrevocably submits to the exclusive jurisdiction of the state and federal courts sitting in The City of New York, Borough of Manhattan, for the
adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein, and hereby irrevocably waives, and agrees not to assert in any suit, action or proceeding, any claim that it is not
personally subject to the jurisdiction of any such court, that such suit, action or proceeding is brought in an inconvenient forum or that the venue of such suit, action or proceeding is improper. Each party hereby irrevocably waives personal
service of process and consents to process being served in any such suit, action or proceeding by mailing a copy thereof to such party at the address for such notices to it under this Agreement and agrees that such service shall constitute good and
sufficient service of process and notice thereof. Nothing contained herein shall be deemed to limit in any way any right to serve process in any manner permitted by law. If any provision of this Agreement shall be invalid or unenforceable in any
jurisdiction, such invalidity or unenforceability shall not affect the validity or enforceability of the remainder of this Agreement in that jurisdiction or the validity or enforceability of any provision of this Agreement in any other jurisdiction.
EACH PARTY HEREBY IRREVOCABLY WAIVES ANY RIGHT IT MAY HAVE, AND AGREES NOT TO REQUEST, A JURY TRIAL FOR THE ADJUDICATION OF ANY DISPUTE HEREUNDER OR IN CONNECTION HEREWITH OR ARISING OUT OF THIS AGREEMENT OR ANY TRANSACTION CONTEMPLATED HEREBY.

 (b) Remedies. In the event of a breach by the Company or by a Holder of any of their
respective 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, shall 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 not assert or shall waive the defense that a remedy at law would be adequate. 

(c) Successors and Assigns. Except as otherwise provided herein, the provisions hereof shall inure to the benefit of, and be binding
upon, the successors, permitted transferees and assignees, executors and administrators of the parties hereto. 
 (d) No Inconsistent
Agreements. The Company has not entered, as of the date hereof, and shall not enter, on or after the date of this Agreement, into any agreement with respect to its securities that would have the effect of impairing the rights granted to the

full and entire understanding and agreement between the parties with regard to the subjects hereof. 
 (f) Notices, etc. All notices
