may request registration under the Securities Act of all or any portion of their Registrable Securities pursuant to a Registration
Statement on Form S-3 (or if not eligible for Form S-3, on Form S-1) or any successor forms thereto (any such registration, a “Demand
Registration”). The request for a Demand Registration shall specify the number of Registrable Securities requested to
be included in the Demand Registration. Upon receipt of any such request, Parent shall promptly (but in no event later than five
Business Days following receipt thereof) deliver notice of such request to all other holders of Registrable Securities who shall
then have 10 days from the date such notice is given to notify Parent in writing of their desire to be included in such registration.
Parent shall prepare and file with (or confidentially submit to) the Commission a Registration Statement on Form S-3 (or if not
eligible for Form S-3, on Form S-1) or any successor forms thereto covering all of the Registrable Securities that the holders
thereof have requested to be included in such Demand Registration within 90 days after the date on which the initial request is
given and shall use its commercially reasonable efforts to cause such Registration Statement to be declared effective by the Commission
as soon as practicable thereafter. Parent shall not be required to effect more than one Demand Registration for the holders of
Registrable Securities.


 


(b)               At
such time as Parent is qualified to use a Registration Statement on Form S-3 or the then appropriate form for an offering to be
made on a delayed or continuous basis pursuant to Rule 415 under the Securities Act or any successor rule thereto (a “Shelf
Registration Statement”), a holder of Registrable Securities shall have the right to request the registration under
the Securities Act of all or any portion of their Registrable Securities for an offering on a delayed or continuous basis pursuant
to Rule 415 under the Securities Act or any successor rule thereto (a “Shelf Registration”). Such request for
a Shelf Registration shall specify the number of Registrable Securities requested to be included in the Shelf Registration. Upon
receipt of any such request, Parent shall promptly (but in no event later than five Business Days following receipt thereof) deliver
notice of such request to all other holders of Registrable Securities, if any, who shall then have 10 days from the date such
notice is given to notify Parent in writing of their desire to be included in such registration. Parent shall prepare and file
with or confidentially submit to the Commission a Shelf Registration Statement covering all of the Registrable Securities that
the holders thereof have requested to be included in such Shelf Registration within 45 days after the date on which the initial
request is given and shall use commercially reasonable efforts to cause such Shelf Registration Statement to be declared effective
by the Commission as soon as practicable thereafter. Each Shelf Registration Statement shall provide for the resale pursuant to
any method or combination of methods legally available to, and requested by, the holders of Registrable Securities. After the
filing of a Shelf Registration Statement, and until all Registrable Securities covered by such Shelf Registration Statement have
ceased to be Registrable Securities, Parent shall use its commercially reasonable efforts to ensure that such Shelf Registration
Statement remains continuously effective.


 






    	 	4	 



     


    

 


(c)               At
any time that the Shelf Registration Statement is effective, if a holder of Registrable Securities covered by such Shelf Registration
Statement delivers a notice to Parent (a “Shelf Takedown Notice”) stating that such holder intends to effect
an offering of all or part of its Registrable Securities included in such Shelf Registration Statement (a “Shelf Takedown”)
and Parent is eligible to use such Shelf Registration Statement for such Shelf Takedown, then Parent shall take all actions reasonably
required, including amending or supplementing such Shelf Registration Statement, to enable such Registrable Securities to be offered
and sold as contemplated by such Shelf Takedown Notice. Each Shelf Takedown Notice shall specify the number of Registrable Securities
to be offered and sold under the Shelf Takedown. Upon receipt of a Shelf Takedown Notice, Parent shall promptly (but in no event
later than 2 Business Days following receipt thereof) deliver notice of such Shelf Takedown Notice to all other holders of Registrable
Securities, if any, who shall then have 5 Business Days from the date such notice is given to notify Parent in writing of their
desire to be included in such Shelf Takedown. Parent shall prepare and file with the Commission a Shelf Supplement as soon as
practicable after the date on which it received the Shelf Takedown Notice and, if such Shelf Supplement is an amendment to such
Shelf Registration Statement, shall use its commercially reasonable efforts to cause such Shelf Supplement to be declared effective
by the Commission as soon as practicable thereafter. The priority for inclusion of Registrable Securities in a Shelf Takedown
will be determined as specified in Section 2(f).


 


(d)               Parent
shall not be obligated to effect any Shelf Takedown within 120 days after the effective date of a previous Shelf Takedown or Demand
Registration in which holders of Registrable Securities were permitted to register the offer and sale under the Securities Act,
and actually sold, at least 50% of the Registrable Securities requested to be included therein. Additionally, Parent shall not
be obligated to effect any Shelf Takedown with respect to any offering that would reasonably be expected to result in net proceeds
of less than $30 million to the participating holders. Parent may postpone for up to 120 days the filing or effectiveness of a
Registration Statement for any Demand Registration or Shelf Takedown and the filing of any Shelf Supplement if the Board determines
in its reasonable good faith judgment that such Demand Registration or Shelf Takedown would: (i) materially interfere with a significant
acquisition, corporate organization, financing, securities offering or other similar transaction involving Parent; (ii) require
premature disclosure of material information that Parent has a bona fide business purpose for preserving as confidential; or (iii)
render Parent unable to materially comply with requirements under the Securities Act or Exchange Act; provided, that in
such event the holders of a majority of the Registrable Securities initiating such Demand Registration or Shelf Takedown shall
be entitled to withdraw such request and, if such request for a Demand Registration or Shelf Takedown is withdrawn, such Demand
Registration or Shelf Takedown shall not count as one of the permitted Demand Registrations or Shelf Takedowns hereunder and Parent
shall pay all registration expenses in connection with such registration. Parent may delay a Demand Registration or Shelf Takedown
hereunder only twice in any period of 12 consecutive months.


 






    	 	5	 



     


    

 


(e)                If
the holders of Registrable Securities initially requesting a Demand Registration or Shelf Takedown elect to distribute the Registrable
Securities covered by their request in an Underwritten Offering, they shall so advise Parent as a part of their request made pursuant
to Section 2(a) or Section 2(b) and Parent shall include such information in its notice to the other holders
of Registrable Securities. Parent, on the one hand, and the holders of the Registrable Securities (pursuant to the consent of
the holders of a majority of the Registrable Securities proposed to be included in such Demand Registration or Shelf Takedown),
on the other, shall each select an investment banking firm to act as one of the two managing underwriters in connection with such
offering; provided, that such selection shall be subject to the consent of the other Party, which consent shall not be
unreasonably withheld or delayed.


 


(f)                Parent may include in any Demand Registration or Shelf Takedown for an Underwritten Offering any securities that are not
Registrable Securities on behalf of Parent or on behalf of a holder of Common Stock that are not Registrable Securities if such
holder has contractual piggyback registration rights and such securities are registered on a Shelf Registration Statement; provided,
however, that if a Shelf Takedown involves an Underwritten Offering and the managing underwriter of the requested Demand
Registration or Shelf Takedown advises Parent and the holders of Registrable Securities in writing that in its reasonable and good
faith opinion the number of shares of Common Stock proposed to be included in the Demand Registration or Shelf Takedown, including
all Registrable Securities and all other shares of Common Stock proposed to be included in such Underwritten Offering, exceeds
the number of shares of Common Stock that can be sold in such Underwritten Offering and/or the number of shares of Common Stock
proposed to be included in such Demand Registration or Shelf Takedown would adversely affect the price per share of the Common
Stock proposed to be sold in such Underwritten Offering, Parent shall include in such Demand Registration or Shelf Takedown (i)
first, the shares of Common Stock that the holders of Registrable Securities propose to sell, and (ii) second, the shares of Common
Stock proposed to be included therein by any other Persons (including shares of Common Stock to be sold for the account of Parent
and/or other holders of Common Stock) allocated among such Persons in such manner as they may agree. If the managing underwriter
determines that less than all of the Registrable Securities proposed to be sold can be included in such offering, then the Registrable
Securities that are included in such offering shall be allocated pro rata among the respective holders thereof on the basis of
the number of shares of Common Stock owned by each such holder or in such manner as they may agree.

3.           Piggyback Sale.


 


(a)               Whenever
Parent proposes the offer and sale of any of the Common Stock or other securities under the Securities Act (other than a registration
(i) pursuant to a Registration Statement on Form S-8 (or other registration solely relating to an offering or sale to employees
or directors of Parent pursuant to any employee stock plan or other employee benefit arrangement), (ii) pursuant to a Registration
Statement on Form S-4 (or similar form that relates to a transaction subject to Rule 145 under the Securities Act or any successor
rule thereto), or (iii) in connection with any dividend or distribution reinvestment or similar plan), whether for its own account
or for the account of one or more stockholders of Parent (a “Piggyback Sale”), Parent shall give prompt written
notice (in any event no later than 10 days prior to the initiation of such offer and sale) to the holders of Registrable Securities
of its intention to effect such an offer and sale and, subject to Sections 3(b) and 3(c), shall include in
such an offer and sale all Registrable Securities with respect to which Parent has received written requests for inclusion from
the holders of Registrable Securities within 7 Business Days after Parent’s notice has been given to each such holder. Parent
may postpone or withdraw such offering or sale at any time in its sole discretion.


 


(b)               If
a Piggyback Sale is initiated as a primary Underwritten Offering on behalf of Parent and the managing underwriter advises Parent
and the holders of Registrable Securities (if any holders of Registrable Securities have elected to include Registrable Securities
in such Piggyback Sale) in writing that in its reasonable and good faith opinion the number of shares of Common Stock proposed
to be included in such registration or takedown, including all Registrable Securities and all other shares of Common Stock proposed
to be included in such Underwritten Offering, exceeds the number of shares of Common Stock that can be sold in such offering and/or
that the number of shares of Common Stock proposed to be included in any such registration or takedown would adversely affect
the price per share of the shares of Common Stock to be sold in such offering, Parent shall include in such registration or takedown
(i) first, the shares of Common Stock that Parent proposes to sell; and (ii) second, the shares of Common Stock requested to be
included therein by holders of Registrable Securities, allocated among such holders pro rata based on the number of shares of
Common Stock held by each applicable holder or in such manner as they may agree.


 


(c)               If
a Piggyback Sale is initiated as an Underwritten Offering on behalf of a holder of shares of Common Stock other than Registrable
Securities, and the managing underwriter advises Parent in writing that in its reasonable and good faith opinion the number of
shares of Common Stock proposed to be included in such registration or takedown, including all Registrable Securities and all
other shares of Common Stock proposed to be included in such Underwritten Offering, exceeds the number of shares of Common Stock
that can be sold in such offering and/or that the number of shares of Common Stock proposed to be included in any such registration
or takedown would adversely affect the price per share of the Common Stock to be sold in such offering, Parent shall include in
such registration or takedown (i) first, the shares of Common Stock requested to be included therein by the holder(s) requesting
such registration or takedown; and (ii) second, the shares of Common Stock requested to be included therein by the holders of
Registrable Securities and by the other holders of shares of Common Stock (other than holders of Registrable Securities) with
registration rights entitling them to participate in such Underwritten Offering, allocated among such holders pro rata on the
basis of the number of shares of Common Stock held by each applicable holder or in such manner as they may agree.


 






    	 	7	 



     


    

 


(d)              
If any Piggyback Sale is initiated as a primary Underwritten Offering on behalf of Parent, Parent shall select the investment
banking firm or firms to act as the managing underwriter or underwriters in connection with such offering.


 


4.           Holdbacks;
Other Restrictions and Acknowledgements.


 


(a)               In
connection with any Underwritten Offering, if requested by the managing underwriter, each Stockholder agrees to enter into customary
agreements restricting the public sale or distribution of equity securities of Parent (including sales pursuant to Rule 144 under
the Securities Act) during the period commencing on the launch of such offering but no earlier than ten (10) days prior to the
 “pricing” of such Underwritten Offering and continuing for not more than ninety (90) days after the date of the “final”
Prospectus (or “final” prospectus supplement if the Underwritten Offering is made pursuant to a Shelf Registration
Statement), pursuant to which such Underwritten Offering shall be made, or such lesser period as is required by the lead managing
underwriter(s).


 


(b)               If
any Demand Registration or Shelf Takedown involves an Underwritten Offering, Parent, if requested by the managing underwriter,
will not effect any public sale or distribution of any common equity (or securities convertible into or exchangeable or exercisable
for common equity) (other than a registration statement on Form S-4, Form S-8 or any successor forms thereto or any other form
for the registration of securities issued or to be issued in connection with a merger, acquisition or employee benefit plan) for
its own account within ninety (90) days after the effective date
of such registration except as may otherwise be agreed between Parent and the lead managing underwriter(s) of such Underwritten
Offering.


 


(c)               Parent
covenants and agrees during the term of this Agreement, without the prior written consent of the Stockholders, not to enter into
any other registration rights agreement that (i) contains registration rights in favor of a third party that would have priority
to the rights of Stockholders contained in this Agreement or (ii) grants any third party with a right to cause Parent to effect
a registration similar to the Demand Registration during such period (unless the Stockholders are permitted to participate pro
rata with such third party in such registration).


 


5.           Registration Procedures. If and whenever the holders of Registrable Securities request that the offer and sale of
any Registrable Securities be registered under the Securities Act or any Registrable Securities be distributed in a Shelf Takedown
pursuant to the provisions of this Agreement, Parent shall use its commercially reasonable efforts to effect the offer and sale
of such Registrable Securities under the Securities Act in accordance with the intended method of disposition thereof, and pursuant

therein of language, furnished to Parent in writing, which in the reasonable judgment of such holder and its counsel should be
included;


 


(r)               cooperate
with the holders of the Registrable Securities to facilitate the timely preparation and delivery of certificates representing
the Registrable Securities to be sold pursuant to such Registration Statement free of any restrictive legends and representing
such number of shares of Common Stock and registered in such names as the holders of the Registrable Securities may reasonably
request a reasonable period of time prior to sales of Registrable Securities pursuant to such Registration Statement; provided,
that Parent may satisfy its obligations hereunder without issuing physical stock certificates through the use of the facilities
of The Depository Trust Company (“DTC”);


 


(s)               not later than the effective date of such Registration Statement, provide a CUSIP number for all Registrable Securities
and provide the applicable transfer agent with printed certificates for the Registrable Securities which are in a form eligible
for deposit with DTC; provided, that Parent may satisfy its obligations hereunder without issuing physical stock certificates
through the use of the facilities of DTC;


 


(t)                take
no direct or indirect action prohibited by Regulation M under the Exchange Act; provided, that, to the extent that any
prohibition is applicable to Parent, Parent will take all commercially reasonable action to make any such prohibition inapplicable;
and


 



    	 	11	 



    


    




 


(u)              otherwise
use its commercially reasonable efforts to take all other steps necessary to effect the registration of such Registrable Securities
contemplated hereby.


 


6.           Expenses. All expenses (other than Selling Expenses) incurred by Parent in complying with its obligations pursuant
to this Agreement and in connection with the registration and disposition of Registrable Securities shall be paid by Parent, including,
without limitation, all (i) registration and filing fees (including, without limitation, any fees relating to filings required
to be made with, or the listing of any Registrable Securities on, any securities exchange or over-the-counter trading market on
which the Registrable Securities are listed or quoted); (ii) underwriting expenses (other than fees, commissions or discounts);
(iii) expenses of any audits incident to or required by any such registration; (iv) fees and expenses of complying with securities
and “blue sky” laws (including, without limitation, fees and disbursements of counsel for Parent in connection with
 “blue sky” qualifications or exemptions of the Registrable Securities) of any domestic jurisdictions, reasonably requested
by the holders of Registrable Securities; (v) printing expenses; (vi) messenger, telephone and delivery expenses; (vii) fees and
expenses of Parent’s counsel and accountants; (viii) Financial Industry Regulatory Authority, Inc. filing fees (if any);
and (ix) reasonable fees and expenses of one counsel for the holders of Registrable Securities participating in such registration
as a group (selected by the holders of a majority of the Registrable Securities being sold in any offering). In addition, Parent
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) and the expense of any annual audits. All Selling Expenses relating to the offer and sale of Registrable Securities registered
under the Securities Act pursuant to this Agreement shall be borne and paid by the holders of such Registrable Securities, in proportion
to the number of Registrable Securities included in such registration for each such holder.


 


7.           Indemnification.


 


(a)               Parent
shall indemnify and hold harmless, to the fullest extent permitted by law, each holder of Registrable Securities, such holder’s
officers, directors, managers, members, partners, stockholders, employees and Affiliates, each underwriter, broker or any other
Person acting on behalf of such holder of Registrable Securities and each other Controlling Person, if any, who controls any of
the foregoing Persons, against all losses, claims, actions, damages, liabilities and expenses, joint or several, to which any
of the foregoing Persons may become subject under the Securities Act or otherwise, insofar as such losses, claims, actions, damages,
liabilities or expenses arise out of or are based upon any untrue or alleged untrue statement of a material fact contained in
any Registration Statement, Prospectus, preliminary Prospectus, free writing prospectus (as defined in Rule 405 under the Securities
Act or any successor rule thereto) or any amendment thereof or supplement thereto or 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 a Prospectus, preliminary Prospectus
or free writing prospectus, in light of the circumstances under which they were made) not misleading; and shall reimburse such
Persons for any legal or other expenses reasonably incurred by any of them in connection with investigating or defending any such
loss, claim, action, damage or liability, except insofar as the same are caused by or contained in any information furnished in
writing to Parent by such holder expressly for use therein or by such holder’s failure to deliver a copy of the Registration
Statement, Prospectus, preliminary Prospectus, free writing prospectus (as defined in Rule 405 under the Securities Act or any
successor rule thereto) or any amendments or supplements thereto (if the same was required by applicable law to be so delivered)
after Parent has furnished such holder with a sufficient number of copies of the same prior to any written confirmation of the
sale of Registrable Securities. This indemnity shall be in addition to any liability Parent may otherwise have.


 






    12 


    


    

 


(b)              In
connection with any registration in which a holder of Registrable Securities is participating, such holder shall furnish to Parent
in writing such information as Parent reasonably requests for use in connection with any such Registration Statement or Prospectus
and, to the extent permitted by law, shall indemnify and hold harmless, Parent, each director of Parent, each officer of Parent
who shall sign such Registration Statement, each underwriter, broker or other Person acting on behalf of the holders of Registrable
Securities and each Controlling Person who controls any of the foregoing Persons against any losses, claims, actions, damages,
liabilities or expenses resulting from any untrue or alleged untrue statement of material fact contained in the Registration Statement,
Prospectus, preliminary Prospectus, free writing prospectus (as defined in Rule 405 under the Securities Act or any successor
rule thereto) or any amendment thereof or supplement thereto or 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 a Prospectus, preliminary Prospectus or free writing
prospectus, in light of the circumstances under which they were made) not misleading, but only to the extent that such untrue
statement or omission is contained in any information so furnished in writing by such holder; provided, that the obligation
to indemnify shall be several, not joint and several, for such holder and shall not exceed an amount equal to the net proceeds
(after underwriting fees, commissions or discounts) actually received by such holder from the sale of Registrable Securities pursuant
to such Registration Statement. This indemnity shall be in addition to any liability the selling holder may otherwise have.


 


(c)               Promptly after receipt by an indemnified party of notice of the commencement of any action involving a claim referred to
in this Section 7, such indemnified party shall, if a claim in respect thereof is made against an indemnifying party,
give written notice to the latter of the commencement of such action. The failure of any indemnified party to notify an indemnifying
party of any such action shall not (unless such failure shall have a material adverse effect on the indemnifying party) relieve
the indemnifying party from any liability in respect of such action that it may have to such indemnified party hereunder. 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 of the claims in any such action that are subject or potentially subject to indemnification hereunder, jointly with
any other indemnifying party similarly notified to the extent that it may wish, with counsel reasonably satisfactory to such indemnified
party, and after written notice from the indemnifying party to such indemnified party of its election so to assume the defense
thereof, the indemnifying party shall not be responsible for any legal or other expenses subsequently incurred by the indemnified
party in connection with the defense thereof; provided, that, if (i) any indemnified party shall have reasonably concluded
that there may be one or more legal or equitable defenses available to such indemnified party which are additional to or conflict
with those available to the indemnifying party, or that such claim or litigation involves or could have an effect upon matters
beyond the scope of the indemnity provided hereunder, or (ii) such action seeks an injunction or equitable relief against any indemnified
party or involves actual or alleged criminal activity, the indemnifying party shall not have the right to assume the defense of
such action on behalf of such indemnified party without such indemnified party’s prior written consent (but, without such
consent, shall have the right to participate therein with counsel of its choice) and such indemnifying party shall reimburse such
indemnified party and any Controlling Person of such indemnified party for that portion of the fees and expenses of any counsel
retained by the indemnified party which is reasonably related to the matters covered by the indemnity provided hereunder. If the
indemnifying party is not entitled to, or elects not to, assume the defense of a claim, it shall not be obligated to pay the fees
and expenses of more than one counsel for all parties indemnified by such indemnifying party with respect to such claim, unless
in the reasonable judgment of any indemnified party a conflict of interest may exist between such indemnified party and any other
of such indemnified parties with respect to such claim. In such instance, the conflicting indemnified parties shall have a right
to retain one separate counsel chosen by the holders of a majority of the Registrable Securities included in the registration,
at the expense of the indemnifying party.


 






    13 


    


    

 


(d)               If
the indemnification provided for hereunder is held by a court of competent jurisdiction to be unavailable to an indemnified party
with respect to any loss, claim, damage, liability or action referred to herein, then the indemnifying party, in lieu of indemnifying
such indemnified party hereunder, shall contribute to the amounts paid or payable by such indemnified party as a result of such
loss, claim, damage, liability or action 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 hand in connection with the statements or omissions that resulted
in such loss, claim, damage, liability or action as well as any other relevant equitable considerations; provided, that
the maximum amount of liability in respect of such contribution shall be limited, in the case of each holder of Registrable Securities,
to an amount equal to the net proceeds (after underwriting fees, commissions or discounts) actually received by such seller from
the sale of Registrable Securities effected pursuant to such registration. 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 or alleged omission to state a material fact relates to information supplied by the indemnifying
party or by the indemnified party, whether the violation of the Securities Act or any other similar federal or state securities
laws or rule or regulation promulgated thereunder applicable to Parent and relating to action or inaction required of Parent in
connection with any applicable registration, qualification or compliance was perpetrated by the indemnifying party or the indemnified
party and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement
or omission. The Parties agree that it would not be just and equitable if contribution pursuant hereto were determined by pro
rata allocation or by any other method or allocation which does not take account of the equitable considerations referred to herein.
No Person guilty or liable of fraudulent misrepresentation within the meaning of Section 11(f) of the Securities Act shall be
entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation.

8.           Participation
in Underwritten Registrations. No Person may participate in any registration hereunder that is underwritten unless such Person
(a) agrees to sell such Person’s securities on the basis provided in any underwriting arrangements approved by the Person
or Persons entitled hereunder to approve such arrangements and (b) completes and executes all questionnaires, powers of attorney,
indemnities, underwriting agreements and other documents reasonably required under the terms of such underwriting arrangements.


 


9.           Rule 144 Compliance. With a view to making available to the holders of Registrable Securities the benefits of Rule
144 and any other rule or regulation of the Commission that may at any time permit a holder to sell securities of Parent to the
public without registration, Parent shall:


 


(a)               use
commercially reasonable efforts to make and keep public information available, as those terms are understood and defined in Rule
144;


 


(b)               use
commercially reasonable efforts to file with the Commission in a timely manner all reports and other documents required of Parent
under the Securities Act and the Exchange Act; and


 


(c)               furnish to any holder so long as such holder owns Registrable Securities, promptly upon request, (i) a written statement
by Parent as to its compliance with the reporting requirements of Rule 144 and of the Securities Act and the Exchange Act, (ii)
a copy of the most recent annual or quarterly report of Parent, unless available in the Electronic Data Gathering, Analysis and
Retrieval database of the Commission (“EDGAR”), (iii) such other reports and documents so filed or furnished
by Parent as such holder may reasonably request in connection with the sale of Registrable Securities without registration and,
unless such reports or documents are available in EDGAR (iv) the opinion of Parent’s counsel, in form and substance reasonably
acceptable to the transfer agent for the Common Stock, relating to such matters as such transfer agent may reasonably request in
connection with the removal of any restrictive legends contained on such Common Stock.


 


10.         Recapitalization, Exchanges, Etc. Affecting the Securities. The provisions of this Agreement shall apply to the full
extent set forth herein with respect to any and all Common Stock of Parent or any successor or assign of Parent (whether by merger,
consolidation, sale of assets or otherwise) that may be issued in respect of, in exchange for or in substitution of, the Registrable
Securities, and shall be appropriately adjusted for combinations, splits, recapitalizations, pro rata distributions and the like
occurring on or after the date of this Agreement.


 


11.         Effective
Date; Termination. This Agreement shall become effective as of the Closing Date, and if the Merger Agreement is terminated
in accordance with its terms, then this Agreement shall terminate and be null and void ab initio. After the Closing Date,
this Agreement shall terminate and be of no further force or effect when there shall no longer be any Registrable Securities outstanding;
provided, that the provisions of Section 6 and Section 7 shall survive any such termination.

13.         Entire
Agreement. This Agreement and any related exhibits and schedules thereto, constitutes the sole and entire agreement of the
Parties to this Agreement with respect to the subject matter contained herein, and supersedes all prior and contemporaneous understandings
and agreements, both written and oral, with respect to such subject matter. Notwithstanding the foregoing, in the event of any
conflict between the terms and provisions of this Agreement, the terms and conditions of this Agreement shall control.


 






    	 	17	 



     


    

 


14.         Successors
and Assigns. This Agreement shall be binding upon and shall inure to the benefit of the Parties hereto and their respective
successors and permitted assigns. Parent may assign this Agreement at any time in connection with a sale or acquisition of Parent,
whether by merger, consolidation, sale of all or substantially all of Parent’s assets, or similar transaction, without the
consent of the Stockholders; provided, that the successor or acquiring Person agrees in writing to assume all of Parent’s
rights and obligations under this Agreement. Each Stockholder may assign its rights hereunder to any purchaser or transferee of
Registrable Securities; provided, that such purchaser or transferee shall, as a condition to the effectiveness of such
assignment, be required to execute a counterpart to this Agreement agreeing to be treated as a Stockholder in Parent whereupon
such purchaser or transferee shall have the benefits of, and shall be subject to the restrictions contained in, this Agreement
as if such purchaser or transferee was originally a Stockholder included in the definition of a Stockholder herein and had originally
been a Party hereto.


 


15.         No Third-Party Beneficiaries. This Agreement is for the sole benefit of the Parties hereto and their respective successors
and permitted assigns and nothing herein, express or implied, is intended to or shall confer upon any other Person any legal or
equitable right, benefit or remedy of any nature whatsoever, under or by reason of this Agreement; provided, however,
the Parties hereto hereby acknowledge that the Persons set forth in Section 7 are express third-party beneficiaries
of the obligations of the Parties hereto set forth in Section 7.


 


16.         Headings.
The headings in this Agreement are for reference only and shall not affect the interpretation of this Agreement.


 


17.         Amendments
and Waivers. No amendment of any provision of this Agreement shall be valid unless the same shall be in writing and signed
by each of the Parties hereto. No waiver by any Party hereto of any default, misrepresentation or breach of warranty or covenant
hereunder, regardless of whether intentional, shall be deemed to extend to any prior or subsequent default, misrepresentation
or breach of warranty or covenant hereunder or affect in any way any rights arising by virtue of any prior or subsequent such
occurrence.


 


18.         Severability.
Any term or provision of this Agreement that is invalid or unenforceable in any situation in any jurisdiction shall not affect
the validity or enforceability of the remaining terms and provisions hereof or the validity or enforceability of the offending
term or provision in any other situation or in any other jurisdiction.


 


19.         Remedies.
Each holder of Registrable Securities that is a Party hereto in addition to being entitled to exercise all rights granted by law,
including recovery of damages, shall be entitled to specific performance of its rights under this Agreement. Parent acknowledges
that monetary damages would not be adequate compensation for any loss incurred by reason of a breach by it of the provisions of
this Agreement and Parent hereby agrees to waive the defense in any action for specific performance that a remedy at law would
be adequate.


 






    	 	18	 



     


    

 


20.         Governing Law; Submission to Jurisdiction. This Agreement shall be governed by and construed in accordance with the
laws of the State of Delaware. Any legal suit, action or proceeding arising out of or based upon this Agreement or the transactions
contemplated hereby may be instituted in the Delaware Chancery Courts located in Wilmington, Delaware, or, if such court shall
not have jurisdiction, any federal court of the United States of America or other Delaware state court located in Wilmington, Delaware,
and appropriate appellate courts therefrom, and each Party irrevocably submits to the exclusive jurisdiction of such courts in
any such suit, action or proceeding. Service of process, summons, notice or other document by mail to such Party’s address
set forth herein shall be effective service of process for any suit, action or other proceeding brought in any such court. The
Parties irrevocably and unconditionally waive any objection to the laying of venue of any suit, action or any proceeding in such
courts, and irrevocably waive and agree not to plead or claim in any such court that any such suit, action or proceeding brought
in any such court has been brought in an inconvenient forum.


 


21.         Waiver
of Jury Trial. Each Party acknowledges and agrees that any controversy which may arise under this Agreement is likely to involve
complicated and difficult issues and, therefore, each such Party irrevocably and unconditionally waives any right it may have
to a trial by jury in respect of any legal action arising out of or relating to this Agreement or the transactions contemplated
hereby. Each Party to this Agreement certifies and acknowledges that (a) no representative of the other Party has represented,
expressly or otherwise, that such other Party would not seek to enforce the foregoing waiver in the event of a legal action, (b)
such Party has considered the implications of this waiver, (c) such Party makes this waiver voluntarily, and (d) such Party has
been induced to enter into this Agreement by, among other things, the mutual waivers and certifications in this Section 21.


 


22.         Counterparts.
This Agreement may be executed in counterparts, each of which shall be deemed an original but which together shall constitute
one and the same instrument. A signed copy of this Agreement delivered by facsimile, e-mail or other means of electronic transmission
shall be deemed to have the same legal effect as delivery of an original signed copy of this Agreement.


 


23.         Further Assurances. Each of the Parties to this Agreement shall, and shall cause their controlled Affiliates to,
execute and deliver such additional documents, instruments, conveyances and assurances and take such further actions as may be
reasonably required to carry out the provisions hereof and to give effect to the transactions contemplated hereby.
