(or any successor form) of Registrable Shares owned by such Stockholder or Stockholders having an aggregate value of at least $25,000,000
(based on the market price or fair value on the date of such request).


 



    	- 6 -



    	 



    

 


(b)          At
any time after the Company becomes eligible to file a Registration Statement on Form S-3 (or any successor form relating to
secondary offerings and allowing for incorporation by reference of reports filed under the Exchange Act), which, to the extent
applicable, will become automatically effective upon filing, a Stockholder or Stockholders (excluding the Founders) may request,
in writing, that the Company file the registration statement on Form S-3 (or such successor form), of Registrable Shares held
by such Stockholder or Stockholders having an aggregate value of at least $5,000,000 (based on the public market price on the date
of such request) and the Company shall use its commercially reasonable efforts to
file a Form S-3 registration statement under the Securities Act covering all Registrable Shares requested to be included in such
registration as soon as practicable, and in
any event within thirty (30) days after the date such request is made to the Company in writing, provided, however, that in the
event that the Company is required to update any of its disclosure pursuant to the Exchange Act, such thirty (30) day filing deadline
shall be extended to the time at which such updated disclosure is required to be filed. 


 


(c)          Upon
receipt of any request for registration pursuant to this Section 2, the Company shall promptly give written notice of such
proposed registration to all other Stockholders. Such Stockholders shall have the right, by giving written notice to the Company
within 15 days after the Company provides its notice, to elect to have included in such registration such of their Registrable
Shares as such Stockholders may request in such notice of election, subject, in the case of an underwritten offering, to the terms
of Section 2.1(d). Thereupon, the Company shall, as expeditiously as possible, use its commercially reasonable efforts to
effect the registration on an appropriate registration form of all the Registrable Shares which the Company has been requested
to so register; provided, however, that in the case of a registration requested under Section 2.1(b), the Company
will only be obligated to file a Form S-3 (or any successor form as aforesaid), which, to the extent applicable, will become
automatically effective upon filing.


 


(d)          If
the Initiating Stockholders intend to distribute the Registrable Shares covered by their request by means of an underwriting, they
shall so advise the Company as a part of their request made pursuant to Section 2.1(a) or (b), as the case may be, and the
Company shall include such information in its written notice referred to in Section 2.1(c). The right of any other Stockholder
to include such Stockholder’s Registrable Shares in such registration pursuant to Section 2.1(a) or (b), as the case
may be, shall be conditioned upon such other Stockholder’s participation in such underwriting on the terms set forth herein.
If the Company desires that any officer or director of the Company holding securities of the Company be included in any registration
for an underwritten offering requested pursuant to Section 2.1 or if Other Holders request such inclusion, the Company may
include the securities of such officers, directors and Other Holders in such registration and underwriting on the terms set forth
herein. The Company shall (together with all Stockholders, officers, directors and Other Holders proposing to distribute their
securities through such underwriting) enter into an underwriting agreement in customary form (including customary indemnification
and contribution provisions on the part of the Company) with the managing underwriter. Notwithstanding any other provision of this
Section 2.1(d), if the managing underwriter advises the Company that marketing factors require a limitation on the number
of shares to be underwritten, the securities of the Company held by officers or directors of the Company (other than Registrable
Shares) and the securities held by Other Holders (other than Registrable Shares) shall be excluded from such registration and underwriting
to the extent deemed advisable by the managing underwriter, and if a further limitation of the number of shares is required, the
number of shares that may be included in such registration and underwriting shall be allocated among all holders of Registrable
Shares requesting registration in proportion, as nearly as practicable, to the respective number of Registrable Shares held by
them on the date of the request for registration made by the Initiating Stockholders pursuant to Section 2.1(a) or (b), as
the case may be. If any such stockholder would thus be entitled to include more shares than such stockholder requested to be registered,
the excess shall be allocated among other participating stockholders pro rata in the manner described in the preceding sentence.
If any holder of Registrable Shares, officer, director or Other Holder who has requested inclusion in such registration as provided
above disapproves of the terms of the underwriting, such person may elect to withdraw therefrom by written notice to the Company,
and the securities so withdrawn shall also be withdrawn from registration. If the managing underwriter has not limited the number
of Registrable Shares or other securities to be underwritten, the Company may include securities for its own account in such registration
if the managing underwriter so agrees and if the number of Registrable Shares and other securities which would otherwise have been
included in such registration and underwriting will not thereby be limited.


 



    	- 7 -



    	 



    

 


(e)          The
Company shall not be required to effect more than three registrations pursuant to Section 2.1(a). In addition, the Company
shall not be required to effect any registration within six months after the effective date of the Registration Statement relating
to the Initial Public Offering. For purposes of this Section 2.1(e), a Registration Statement shall not be counted until such
time as such Registration Statement has been declared effective by the Commission, unless the Initiating Stockholders withdraw
their request for such registration (other than as a result of information concerning the business or financial condition of the
Company that is made known to the Stockholders after the date on which such registration was requested) and elect not to pay the
Registration Expenses therefor pursuant to Section 2.4.


 


(f)          If
at the time of any request to register Registrable Shares by an Initiating Stockholder pursuant to this Section 2.1, the Company
is engaged or has plans to engage in a registered public offering or is engaged in any other activity which, in the good faith
determination of the Company’s Board of Directors, would be adversely affected by the requested registration, then the Company
may at its option direct that such request be delayed for a period not in excess of 120 days (or 180 days in connection with the
Company’s Initial Public Offering) from the date of such request, such right to delay a request to be exercised by the Company
not more than twice in any 12-month period.


 


(g)          Notwithstanding
the foregoing, the Company shall not be required, pursuant to this Section 2.1, to include any Registrable Shares in a Registration
Statement if such Registrable Shares can then be sold pursuant to Rule 144(b)(1) under the Securities Act or any successor rule
or regulation of the Commission issued under such Act.


 


2.2          Incidental
Registration.


 


(a)          Whenever
the Company proposes to file a Registration Statement covering Common Stock (other than a Registration Statement filed pursuant
to Section 2.1 or in connection with an Initial Public Offering) at any time and from time to time, it will, prior to such
filing, give written notice to all Stockholders of its intention to do so; provided, however, that no such notice
need be given if no Registrable Shares are to be included therein as a result of a determination of the managing underwriter pursuant
to Section 2.2(b). Upon the written request of a Stockholder or Stockholders, given within 15 days after the Company provides
such notice (which request shall state the intended method of disposition of such Registrable Shares), the Company shall use its
commercially reasonable efforts to cause all Registrable Shares which the Company has been requested by such Stockholder or Stockholders
to register to be registered under the Securities Act to the extent necessary to permit their sale or other disposition in accordance
with the intended methods of distribution specified in the request of such Stockholder or Stockholders; provided, however,
that the Company shall have the right to postpone or withdraw any registration effected pursuant to this Section 2.2 two (2)
times in any twelve (12) month period, without obligation to any Stockholder, any such postponement not to exceed a period of ninety
(90) days in aggregate, subject to applicable law.


 



    	- 8 -



    	 



    

 


(b)          If
the registration for which the Company gives notice pursuant to Section 2.2(a) is a registered public offering involving an
underwriting, the Company shall so advise the Stockholders as a part of the written notice given pursuant to Section 2.2(a).
In such event, the right of any Stockholder to include such Stockholder’s Registrable Shares in such registration pursuant
to Section 2.2 shall be conditioned upon such Stockholder’s participation in such underwriting on the terms set forth
herein. All Stockholders proposing to distribute their securities through such underwriting shall enter into an underwriting agreement
in customary form with the underwriter or underwriters selected for the underwriting by the Company. Notwithstanding any other
provision of this Section 2.2, if the managing underwriter determines that marketing factors require a limitation on the number
of shares to be underwritten, the Company may limit the number of Registrable Shares to be included in the registration and underwriting.
The Company shall so advise all holders of Registrable Shares requesting registration, and the number of shares that are entitled
to be included in the registration and underwriting shall be allocated in the following manner. The securities of the Company held
by holders other than Stockholders and Other Holders shall be excluded from such registration and underwriting to the extent deemed
advisable by the managing underwriter, and, if a further limitation on the number of shares is required, the number of shares that
may be included in such registration and underwriting shall be allocated among all Stockholders and Other Holders requesting registration
in proportion, as nearly as practicable, to the respective number of shares of Common Stock (on an as-converted basis) that they
held at the time the Company gives the notice specified in Section 2.2(a). If any Stockholder or Other Holder would thus be
entitled to include more securities than such holder requested to be registered, the excess shall be allocated among other requesting
Stockholders and Other Holders pro rata in the manner described in the preceding sentence. If any holder of Registrable
Shares or any officer, director or Other Holder disapproves of the terms of any such underwriting, such person may elect to withdraw
therefrom by written notice to the Company, and any Registrable Shares or other securities excluded or withdrawn from such underwriting
shall be withdrawn from such registration. Notwithstanding the foregoing, the Company shall not be required, pursuant to this Section 2.2,
to include any Registrable Shares in a Registration Statement if such Registrable Shares can then be sold pursuant to Rule 144(b)(1)
under the Securities Act or any successor rule or regulation of the Commission issued under such Act.


 


2.3          Registration
Procedures.


 


(a)          If
and whenever the Company is required by the provisions of this Agreement to use its commercially reasonable efforts to effect the
registration of any Registrable Shares under the Securities Act, the Company shall:


 


(i)          file
with the Commission a Registration Statement with respect to such Registrable Shares and use its commercially reasonable efforts
to cause that Registration Statement to become effective as soon as possible;


 


(ii)         as
expeditiously as possible prepare and file with the Commission any amendments and supplements to the Registration Statement and
the prospectus included in the Registration Statement as may be necessary to comply with the provisions of the Securities Act (including
the anti-fraud provisions thereof) and to keep the Registration Statement effective for 180 days from the effective date or such
lesser period until all such Registrable Shares are sold;


 


(iii)        as
expeditiously as possible furnish to each Selling Stockholder such reasonable numbers of copies of the Prospectus, including any
preliminary Prospectus, in conformity with the requirements of the Securities Act, and such other documents as such Selling Stockholder

Stockholder;

public sale or other disposition in such states of the Registrable Shares owned by the Selling Stockholder; provided, however,
that the Company shall not be required in connection with this paragraph (iv) to qualify generally to do business as a foreign
corporation in any jurisdiction where it is not so qualified or to subject itself to taxation in respect of doing business in any
such jurisdiction or to execute a general consent to service of process in any jurisdiction or to amend its Certificate of Incorporation
or By-laws in a manner that the Board of Directors of the Company determines is inadvisable;


 


(v)         use
commercially reasonable efforts to cause the Registrable Shares to be registered with or approved by such other governmental agencies

expeditiously as possible, cause all such Registrable Shares to be listed on each securities exchange or automated quotation system

and make members of senior management of the Company available on a basis reasonably requested by the underwriters to participate

of the Registrable Shares) and cause to be delivered to the underwriters reasonable opinions of counsel to the Company in customary
form, covering such matters as are customarily covered by opinions for an underwritten public offering as the underwriters may
reasonably request.


 


(viii)      promptly
provide a transfer agent and registrar for all such Registrable Shares not later than the effective date of such registration statement;


 


(ix)         promptly
make available for inspection by the Selling Stockholders, any managing underwriter participating in any disposition pursuant to
such Registration Statement, and any attorney or accountant or other agent retained by any such underwriter or selected by the
Selling Stockholders, all financial and other records, pertinent corporate documents and properties of the Company and cause the
Company’s officers, directors, employees and independent accountants to supply all information reasonably requested by any
such seller, underwriter, attorney, accountant or agent in connection with such Registration Statement;


 


(x)          notify
the Selling Stockholders promptly, and (if requested by such person) confirm such notice in writing, if at any time (a) the
representations or warranties of the Company contained in any agreement (including the underwriting agreement) contemplated by
Section 2.3 cease to be true and correct in any material respect; or (b) an event occurs which makes any statement made
in such Registration Statement or related Prospectus or any document incorporated or deemed to be incorporated therein by reference
untrue in any material respect or that requires the making of any changes in such Registration Statement, Prospectus or documents
so that, in the case of the Registration Statement it will not contain any untrue statement of a material fact or omit to state
any material fact required to be stated therein or necessary to make the statements therein not misleading, and in the case of
the Prospectus, it will not contain any untrue statement of a material fact or omit to state any material fact required to be stated
therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading;


 



    	- 10 -



    	 



    

 


(xi)         as
expeditiously as possible, notify each Selling Stockholder, promptly after it shall receive notice thereof, of the time when such
Registration Statement has become effective or a supplement to any Prospectus forming a part of such Registration Statement has
been filed;


 


(xii)        as
expeditiously as possible following the effectiveness of such Registration Statement, notify each seller of such Registrable Shares
of any request by the Commission for the amending or supplementing of such Registration Statement or Prospectus; and


 


(xiii)       after
the filing of a Registration Statement, (a) promptly notify each Stockholder holding Registrable Shares covered by such Registration
Statement of any stop order issued or, to the Company’s knowledge, threatened by the Commission and of the receipt by the
Company of any notification with respect to the suspension of the qualification of any Registrable Shares for sale under the applicable
securities or Blue Sky laws of any jurisdiction and (b) promptly take all reasonable actions to obtain the withdrawal of any
order suspending the effectiveness of the Registration Statement or the qualification of the Registrable Shares.


 


(b)          If
the Company has delivered a Prospectus to the Selling Stockholders and after having done so the Prospectus is amended to comply
with the requirements of the Securities Act, the Company shall promptly notify the Selling Stockholders and, if requested, the
Selling Stockholders shall immediately cease making offers of Registrable Shares and return all Prospectuses to the Company. The
Company shall promptly provide the Selling Stockholders with revised Prospectuses and, following receipt of the revised Prospectuses,
the Selling Stockholders shall be free to resume making offers of the Registrable Shares.


 


(c)          In
the event that, in the judgment of the Company, it is advisable to suspend use of a Prospectus included in a Registration Statement
due to pending material developments or other events that have not yet been publicly disclosed and as to which the Company believes
public disclosure would be detrimental to the Company, the Company shall notify all Selling Stockholders to such effect, and, upon
receipt of such notice, each such Selling Stockholder shall immediately discontinue any sales of Registrable Shares pursuant to
such Registration Statement until such Selling Stockholder has received copies of a supplemented or amended Prospectus or until
such Selling Stockholder is advised in writing by the Company that the then current Prospectus may be used and has received copies
of any additional or supplemental filings that are incorporated or deemed incorporated by reference in such Prospectus. Notwithstanding
anything to the contrary herein, the Company shall not exercise its rights under this Section 2.3(c) to suspend sales of Registrable
Shares for a period in excess of 120 days in any 12-month period.


 


2.4          Allocation
of Expenses. The Company shall pay all Registration Expenses for all registrations under this Agreement; provided, however,
that if a registration under Section 2.1 is withdrawn at the request of the Initiating Stockholders (other than as a result
of information concerning the business or financial condition of the Company that is made known to the Stockholders after the date
on which such registration was requested) and if the Initiating Stockholders elect not to have such registration counted as a registration
requested under Section 2.1, the requesting Stockholders shall pay the Registration Expenses of such registration pro rata
in accordance with the number of their Registrable Shares included in such registration.

2.5          Indemnification
and Contribution.


 


(a)          In
the event of any registration of any of the Registrable Shares under the Securities Act pursuant to this Agreement, the Company
will indemnify and hold harmless each Selling Stockholder, each underwriter of such Registrable Shares, and each other person,
if any, who controls such Selling Stockholder or underwriter within the meaning of the Securities Act or the Exchange Act against
any losses, claims, damages or liabilities, joint or several, to which such Selling Stockholder, underwriter or controlling person
may become subject under the Securities Act, the Exchange Act, state securities or Blue Sky laws or otherwise, insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged
untrue statement of any material fact contained in any Registration Statement under which such Registrable Shares were registered
under the Securities Act, any preliminary prospectus or final prospectus contained in the Registration Statement, or any amendment
or supplement to such Registration Statement, or arise out of or are based upon the omission or alleged omission to state a material
fact required to be stated therein or necessary to make the statements therein not misleading; and the Company will reimburse such
Selling Stockholder, underwriter and each such controlling person for any legal or any other expenses reasonably incurred by such
Selling Stockholder, underwriter or controlling person in connection with investigating or defending any such loss, claim, damage,
liability or action; provided, however, that the Company will not be liable in any such case to the extent that any
such loss, claim, damage or liability arises out of or is based upon any untrue statement or omission made in such Registration
Statement, preliminary prospectus or prospectus, or any such amendment or supplement, in reliance upon and in conformity with information
furnished to the Company, in writing, by or on behalf of such Selling Stockholder, underwriter or controlling person specifically
for use in the preparation thereof.


 


(b)          In
the event of any registration of any of the Registrable Shares under the Securities Act pursuant to this Agreement, each Selling
Stockholder, severally and not jointly, will indemnify and hold harmless the Company, each of its directors and officers and each
underwriter (if any) and each person, if any, who controls the Company or any such underwriter within the meaning of the Securities
Act or the Exchange Act, against any losses, claims, damages or liabilities, joint or several, to which the Company, such directors
and officers, underwriter or controlling person may become subject under the Securities Act, Exchange Act, state securities or
Blue Sky laws or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of
or are based upon any untrue statement or alleged untrue statement of a material fact contained in any Registration Statement under
which such Registrable Shares were registered under the Securities Act, any preliminary prospectus or final prospectus contained
in the Registration Statement, or any amendment or supplement to the Registration Statement, or arise out of or are based upon
any omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements therein
not misleading, if the statement or omission was made in reliance upon and in conformity with information relating to such Selling
Stockholder furnished in writing to the Company by or on behalf of such Selling Stockholder specifically for use in connection
with the preparation of such Registration Statement, prospectus, amendment or supplement; provided, however, that
the obligations of a Selling Stockholder hereunder shall be limited to an amount equal to the net proceeds to such Selling Stockholder
of Registrable Shares sold in connection with such registration.


 


(i)          Each
party entitled to indemnification under this Section 2.5 (the “Indemnified Party”) shall give notice to
the party required to provide indemnification (the “Indemnifying Party”) promptly after such Indemnified Party
has actual knowledge of any claim as to which indemnity may be sought, and shall permit the Indemnifying Party to assume the defense
of any such claim or any litigation resulting therefrom; provided that counsel for the Indemnifying Party, who shall conduct
the defense of such claim or litigation, shall be approved by the Indemnified Party (whose approval shall not be unreasonably withheld);
and, provided further that the failure of any Indemnified Party to give notice as provided herein shall not relieve
the Indemnifying Party of such Indemnifying Party’s obligations under this Section 2.5 except to the extent that the
Indemnifying Party is adversely affected by such failure. The Indemnified Party may participate in such defense at such party’s
expense; provided, however, that the Indemnifying Party shall pay such expense if representation of such Indemnified
Party by the counsel retained by the Indemnifying Party would be inappropriate due to actual or potential differing interests between
the Indemnified Party and any other party represented by such counsel in such proceeding; provided further that in
no event shall the Indemnifying Party be required to pay the expenses of more than one law firm per jurisdiction as counsel for
the Indemnified Party. The Indemnifying Party also shall be responsible for the expenses of such defense if the Indemnifying Party
does not elect to assume such defense. No Indemnifying Party, in the defense of any such claim or litigation shall, except with
the consent of each Indemnified Party, consent to entry of any judgment or enter into any settlement which does not include 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, and no Indemnified Party shall consent to entry of any judgment or settle such claim or
litigation without the prior written consent of the Indemnifying Party, which consent shall not be unreasonably withheld.


 



    	- 12 -



    	 



    

 


(c)          In
order to provide for just and equitable contribution in circumstances in which the indemnification provided for in this Section 2.5
is due in accordance with its terms but for any reason is held to be unavailable to an Indemnified Party in respect to any losses,
claims, damages and liabilities referred to herein, then the Indemnifying Party shall, in lieu of indemnifying such Indemnified
Party, contribute to the amount paid or payable by such Indemnified Party as a result of such losses, claims, damages or liabilities
to which such party may be subject in such proportion as is appropriate to reflect the relative fault of the Company on the one
hand and the Selling Stockholders on the other in connection with the statements or omissions which resulted in such losses, claims,
damages or liabilities, as well as any other relevant equitable considerations. The relative fault of the Company and the Selling
Stockholders shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of material
fact related to information supplied by the Company or the Selling Stockholders and the parties’ relative intent, knowledge,
access to information and opportunity to correct or prevent such statement or omission. The Company and the Selling Stockholders
agree that it would not be just and equitable if contribution pursuant to this Section 2.5, were determined by pro rata
allocation or by any other method of allocation which does not take account of the equitable considerations referred to above.
Notwithstanding the provisions of this paragraph of Section 2.5, (a) in no case shall any one Selling Stockholder be
liable or responsible for any amount in excess of the net proceeds received by such Selling Stockholder from the offering of Registrable
Shares and (b) the Company shall be liable and responsible for any amount in excess of such proceeds; provided, however,
that no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be
entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. Any party entitled to contribution
will, promptly after receipt of notice of commencement of any action, suit or proceeding against such party in respect of which
a claim for contribution may be made against another party or parties under this Section 2.5, notify such party or parties
from whom contribution may be sought, but the omission so to notify such party or parties from whom contribution may be sought
shall not relieve such party from any other obligation it or they may have thereunder or otherwise under this Section 2.5.
No party shall be liable for contribution with respect to any action, suit, proceeding or claim settled without such party’s
prior written consent, which consent shall not be unreasonably withheld.


 


(d)          Unless
otherwise expressly agreed to in writing by a holder of Registrable Shares, or otherwise required by applicable law or the rules
of any national exchange on which the Company’s Common Stock is listed, the only information furnished or to be furnished
to the Company for use in any registration statement or prospectus relating to the Registrable Shares or in any amendment, supplement
or preliminary materials associated therewith are statements specifically relating to (i) the beneficial ownership of shares of
Common Stock by such holder and its Affiliates, (ii) the name and address of such holder and (iii) any additional information about
such holder or the plan of distribution required by law or regulation to be disclosed in any such document.

2.6          Other
Matters with Respect to Underwritten Offerings. In the event that Registrable Shares are sold pursuant to a Registration Statement
in an underwritten offering pursuant to Section 2.1, the Company agrees to use its commercially reasonable efforts to cause
(a) its legal counsel to render customary opinions with respect to the Registration Statement to the underwriters and to selling
Stockholders that represent that they have an obligation to perform a due diligence review process under the Securities Act of
1933 and (b) its independent public accounting firm to issue customary “cold comfort letters” with respect to
the Registration Statement to the underwriters and selling Stockholders that represent that they have an obligation to perform
a due diligence review process under the Securities Act of 1933.


 


2.7          Information
by Stockholder. Each holder of Registrable Shares included in any registration shall furnish to the Company such information
regarding such holder and the distribution proposed by such holder as the Company may reasonably request in writing and as shall
be required in connection with any registration, qualification or compliance referred to in this Agreement.


 


2.8          “Lock-Up”
Agreement; Confidentiality of Notices.


 


(a)          Each
Holder hereby agrees that it will not, without the prior written consent of the managing underwriter, during the period commencing
on the date of the final prospectus relating to the registration
by the Company of shares of its Common Stock or any other equity securities under the
Securities Act on a registration statement on Form
S-1 or Form S-3 and ending on the date specified by the Company
and the managing underwriter (such period not to exceed (x) one hundred eighty (180) days in the case of the Initial Public
Offering, or (y) ninety (90) days in the case of any
registration other than the Initial Public Offering, or,
in either case, such other period as may be
requested by the Company or an underwriter to accommodate regulatory restrictions on (1) the publication or other distribution
of research reports and (2) analyst recommendations and opinions, including, but not limited to, the restrictions contained in
FINRA Rule 2711(f)(4) or NYSE Rule 472(f)(4), or any successor provisions or amendments thereto), (i) lend; offer; pledge;
sell; contract to sell; sell any option or contract to purchase; purchase any option or contract to sell; grant any option, right,
or warrant to purchase; or otherwise transfer or dispose of, directly or indirectly, any shares of Common Stock or any securities
convertible into or exercisable or exchangeable (directly or indirectly)
for Common Stock held immediately before the effective date of the registration statement for such offering or
(ii) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences
of ownership of such securities, whether any such transaction
described in clause (i) or (ii) above is to be settled by delivery of Common Stock or other securities, in cash, or otherwise.
The foregoing provisions of this Section 2.8 shall
not apply to the sale of any shares to an underwriter pursuant to an underwriting agreement, and shall be applicable to the Holders
only if all officers and directors are subject to the same restrictions and the Company uses commercially reasonable efforts to
obtain a similar agreement from all stockholders individually owning more than one percent (1%) of the Company’s outstanding
shares of Common Stock (after giving effect to conversion into Common Stock of all outstanding shares of Series A Stock, Series
B Stock and Series C Stock). The underwriters in connection with such
registration are intended third-party beneficiaries of this
Section 2.8 and shall have the right, power, and authority to enforce the provisions hereof as though they were a party hereto.
Each Holder further agrees to execute such agreements as may be reasonably requested by the underwriters in connection
with such registration that are consistent with this Section 2.8 or that are necessary to give further effect thereto.


 


(b)          The
Company may impose stop-transfer instructions with respect to the Registrable Shares or other securities subject to the foregoing
restriction until the end of such “lock-up” period.


 



    	- 14 -



    	 



    

 


(c)          Any
Stockholder receiving any written notice from the Company regarding the Company’s plans to confidentially submit or file
a Registration Statement shall treat such notice confidentially and shall not disclose such information to any person other than
as necessary to exercise such Stockholder’s rights under this Agreement.


 


2.9          Limitations
on Subsequent Registration Rights. The Company shall not, prior to the Initial Public Offering, without the prior written consent
of Requisite Holders, to the extent any Preferred Stock is outstanding and if no Preferred Stock is then outstanding, the prior
written consent of the holders of 80% of the Registrable Shares then held by all Stockholders, enter into any agreement (other
than this Agreement) with any holder or prospective holder of any securities of the Company that grants such holder or prospective
holder rights to include securities of the Company in any Registration Statement, unless (a) such rights to include securities
in a registration initiated by the Company or by Stockholders are not more favorable than the rights granted to Other Holders under
Sections 2.1 and 2.2 of this Agreement, and (b) no rights are granted to initiate a registration, other than registration
pursuant to a registration statement on Form S-3 (or a successor form as aforesaid) in which Stockholders are entitled to
include Registrable Shares on a pro rata basis with such holders based on the number of shares of Common Stock (on an as-converted
basis) owned by Stockholders and such holders.


 


2.10        Rule
144 Requirements. After the earliest of (i) the closing of the sale of securities of the Company pursuant to a Registration
Statement, (ii) the registration by the Company of a class of securities under Section 12 of the Exchange Act and (iii) the
issuance by the Company of an offering circular pursuant to Regulation A under the Securities Act, the Company agrees to:


 


(a)          make
and keep current public information about the Company available, as those terms are understood and defined in Rule 144 under
the Securities Act or any successor rule or regulation of the Commission issued under such Act;


 


(b)          use
its commercially reasonable efforts to file with the Commission in a timely manner all reports and other documents required of
the Company under the Securities Act and the Exchange Act (at any time after it has become subject to such reporting requirements);
and


 


(c)          furnish
to any holder of Registrable Shares upon request (i) a written statement by the Company as to its compliance with the reporting
requirements of Rule 144 and of the Securities Act or any successor rule or regulation of the Commission issued under such
Act and the Exchange Act (at any time after it has become subject to such reporting requirements), (ii) a copy of the most
recent annual or quarterly report of the Company and (iii) such other reports and documents of the Company as such holder
may reasonably request to avail itself of any similar rule or regulation of the Commission allowing it to sell any such securities
without registration.


 


2.11        Transfers
of Rights. Except as set forth in Section 2.8, the rights and obligations of each Stockholder under this Section 2
may be assigned by such Stockholder to (i) any person or entity to which at least 500,000 Shares (subject to appropriate adjustment
for stock splits, stock dividends, recapitalizations and similar events occurring after the date of this Agreement) are transferred
by such Stockholder or (ii) any partner, stockholder or affiliate of such Stockholder, and such transferee shall be deemed
a “Stockholder” for purposes of this Agreement; provided that, in each case, the transferee provides written
notice of such assignment to the Company and agrees in writing to be bound hereby.

2.12        Legends.
Upon request of a Holder following the effectiveness of a Registration Statement covering Shares held by such Holder, the Company
shall as soon as practicable (but not later than five business days after the effectiveness of such Registration Statement), remove
from such Shares the restrictive legends set forth in Section 8.2(b). The Company shall cause its counsel to issue a legal
opinion to the Company’s transfer agent promptly after the effectiveness of the Registration Statement if required by the
Company’s transfer agent to effect the removal of legends pursuant to this Section 2.12. Following the effectiveness
of a Registration Statement covering Shares, the Company shall issue a blanket letter of instruction to its transfer agent placing
a “stop transfer” order on the Shares covered by such Registration Statement, which stop transfer order may be lifted
with respect to the applicable Shares only (i) upon receipt by the transfer agent of written certification from the Holder of such
Shares that the Shares have been sold pursuant to the effective Registration Statement and a duly delivered prospectus or (ii)
unless the Shares have been sold in a transaction not subject to the registration requirements of the Securities Act and the Company
has received an opinion of counsel to the extent required by Section 8.1.


 


2.13        Pledges
Pursuant to Margin Agreements. After the effectiveness of a Registration Statement with respect to such Shares, the Company
acknowledges and agrees that a Stockholder may from time to time pledge pursuant to a bona fide margin agreement with a registered
broker-dealer or grant a security interest in some or all of the Shares to a financial institution that is an “accredited
investor” as defined in Rule 501(a) under the Securities Act and, if required under the terms of such arrangement, such
Stockholder may transfer pledged or secured Shares to the pledgees or secured parties. Such a pledge or transfer shall not be subject
to approval of the Company nor shall any notice be required of such pledge. The Company will execute and deliver such documentation
as a pledgee or secured party of Shares pursuant to this Section 2.13 may reasonably request in connection with such pledge
or transfer, including the preparation and filing of any required prospectus supplement under Rule 424(b)(3) of the Securities
Act or other applicable provision of the Securities Act to appropriately amend the list of selling stockholders thereunder, provided
that the Company may first require a legal opinion of legal counsel of the pledgee, secured party or pledgor in connection therewith
and that states the exemption from registration under the Securities Act that is applicable to such transfer or pledge.


 


2.14        Termination.
All of the Company’s obligations to register Registrable Shares under Sections 2.1 and 2.2 shall terminate upon the
earliest of (a) three years after the closing of the Initial Public Offering, (b) the date on which no Stockholder holds
any Registrable Shares or (c) the sale of all or substantially all of the assets or business of the Company, by merger, sale
of assets or otherwise.

director elected pursuant to paragraph (a), (b), (c) or (d) of Section 3.1 of this Agreement may be removed from office (other

the affirmative vote of the Person(s) entitled under the applicable paragraph of Section 3.1 to designate that director or

Revocation. The voting agreements contained in this Section 3 are coupled with an interest and may not be revoked, except

3.6          OrbiMed

“OrbiMed Observer”) attend each meeting of the Board in a non-voting observer capacity. The Company shall deliver
to the OrbiMed Observer notice of such meetings in accordance with the Company’s by-laws and shall give the OrbiMed Observer

Board concerning specific information, that the Board (excluding any directors designated by OrbiMed) determines is (a) competitively

5.           Right
of First Refusal.


 


5.1          General
Restriction.


 


(a)          Any
sale, transfer, pledge, hypothecation or other disposition, whether voluntarily or by operation of law (a “Transfer”)
of any of the Shares by a Founder, other than according to the terms of this Agreement, shall be void and transfer no right, title,
or interest in or to any of such Shares to the purported transferee.


 


(b)          Notwithstanding
anything contained herein to the contrary, for so long as a Founder has an ongoing employment or contractual relationship with
the Company, such Founder shall not Transfer his Shares (other than pursuant to Section 5.2) for a period of one year from
the date of this Agreement.


 


(c)          The
proceeds of any sale made by the Selling Founder without compliance with the provisions of this Section 5 shall be deemed
to be held in constructive trust in such amount as would have been due to the New Investors if the Selling Founder had complied
with this Agreement.


 


5.2          Transfers
Not Subject to Restrictions. Any Founder may Transfer Shares to such Founder’s spouse or children or to a trust established
for the benefit of such Founder’s spouse, children or such Founder, or dispose of them under such Founder’s will, without
compliance with Sections 5.3 through 5.6 hereof; provided that the transferee delivers to the Company a written
instrument agreeing to be bound by the terms of this Section 5 as if such transferee were a Founder. The rights of the Company
and the Stockholders under Section 5 shall not apply to any pledge of Shares by a Founder which creates a mere security interest
with no assignment of the voting right, provided the pledgee provides the Company with a written agreement to be bound hereby
to the same extent as the pledging Founder.


 


5.3          Offer
of Sale; Notice of Proposed Sale. If any Founder desires to Transfer any of such Founder’s Shares in any transaction
other than pursuant to Section 5.2 of this Agreement, such Founder (the “Selling Founder”) shall first
deliver written notice of such Founder’s desire to do so (the “Founder Notice”) to the Company and the
New Investors, in the manner prescribed by Section 9(d) of this Agreement. The Founder Notice must specify: (i) the name
and address of the party to which the Selling Founder proposes to sell or otherwise dispose of the Shares or an interest in the
Shares (the “Offeror”), (ii) the number of Shares the Selling Founder proposes to sell or otherwise dispose
of (the “Offered Shares”), (iii) the consideration per Share to be delivered to the Selling Founder for
the proposed sale, transfer or disposition, (iv) include an offer to sell the Offered Shares to the New Investors and the
Company on the terms set forth in Sections 5.4 and 5.5 and (v) all other material terms and conditions of the proposed
transaction.


 


5.4          Stockholders’
Option to Purchase.


 


(a)          The
New Investors shall have the first right of first refusal (the “Investor ROFR”), exercisable for a period of
10 business days from the date of delivery of the Founder Notice (the “Investor ROFR Period”), to purchase any
or all of their pro rata portion of the Offered Shares for the consideration per share and on the terms and conditions set
forth in the Founder Notice, with the pro rata portion of the Offered Shares being determined by multiplying (x) the
number of Shares then held by a New Investor, by (y) a fraction, the numerator of which shall be the aggregate number of Shares
then held by such New Investor and the denominator of which shall be the total number of Shares then held by all New Investors.
The Investor ROFR shall be exercised by delivery by the New Investors of written notice to the Selling Founder and the Secretary
of the Company specifying the number of Shares to be purchased (the “Investor ROFR Notice”). Alternatively,
the New Investors may within the Investor ROFR Period, notify the Selling Founder and the Secretary of the Company of their desire
to participate in the sale of the Shares on the terms set forth in the Founder Notice in accordance with Section 5.6, and
the number of Shares such New Investor wishes to sell pursuant to such provision (such Shares, the “Participating Shares”).


 



    	- 20 -



    	 



    

 


(b)          If
options to purchase have been exercised pursuant to Section 5.4(a) for some but not all of the Offered Shares by the end of the
Investor ROFR Period, then the Company shall, promptly after the expiration of the Investor ROFR Period, send written notice (the
“Company Undersubscription Notice”) to those New Investors who fully exercised their Investor ROFR within the
Investor ROFR Period (the “Exercising Investors”). Each Exercising Investor shall, subject to the provisions
of this Section 5.4(b), have an additional option to purchase all or any part of the balance of any such remaining unsubscribed
Offered Shares on the terms and conditions set forth in the Founder Notice. To exercise such option, an Exercising Investor must
deliver written notice to the Selling Founder and the Secretary of the Company within five (5) days after the expiration of the
Investor ROFR Period (the “Undersubscription Period”). In the event there are two or more such Exercising Investors
that choose to exercise the last-mentioned option for a total number of remaining shares in excess of the number available, the
remaining shares available for purchase under this Section 5.4(b) shall be allocated to such Exercising Investors pro rata based
on the number of Offered Shares such Exercising Investors have elected to purchase pursuant to the Investor ROFR (without giving
effect to any Offered Shares that any such Exercising Investor has elected to purchase pursuant to the Company Undersubscription
Notice). If the options to purchase the remaining shares are exercised in full by the Exercising Investors, the Company shall promptly
notify all of the New Investors and the Selling Founder of that fact.


 


(c)          The
closing of the purchase of the Offered Shares pursuant to this Section 5.4 shall take place at the offices of the Company
no later than five (5) business days after the earlier of (i) the date upon which the New Investors shall have exercised the
Investor ROFR for all of the Offered Shares and (ii) the earlier of the expiration of the Company ROFR Period (as defined
below) and the date on which the Company provides written notice exercising or refusing to exercise the Company ROFR (as defined
below) (the “ROFR Purchase Date”). At such closing, the Selling Founder shall convey record and beneficial ownership
of the Offered Shares to the applicable Stockholder(s) electing to purchase the Offered Shares in accordance with this Section 5.4
at a time and place specified by such Stockholder(s) by delivering certificates representing the Offered Shares so purchased, duly
endorsed for transfer or accompanied by duly and validly executed stock powers endorsed in blank.


 


(d)          If
all of the New Investors fail to exercise the Investor ROFR during the Investor ROFR Period, the New Investors shall be deemed
to have rejected the Investor ROFR.


 


(e)          At
the end of the Investor ROFR Period or Undersubscription Period, as applicable, any Offered Shares that have not been designated
for purchase by the New Investors shall be referred to as the “Remaining Shares”.


 


5.5          Company
Option to Purchase.


 


(a)          Subject
to Section 5.4, if there are any Remaining Shares at the end of the Investor ROFR Period or Undersubscription Period, as applicable,
the Company shall have the right of first refusal (the “Company ROFR”) exercisable for a period of 15 business
days from the expiration of the later of the Investor ROFR Period or Undersubscription Period (the “Company ROFR Period”)
to purchase all or part of the Remaining Shares for the consideration per share and on the terms and conditions specified in the
Founder Notice. Any Remaining Shares with regard to which the Company has not exercised its right of first refusal shall be referred
to as the “Final Remaining Shares.” The Company ROFR shall be exercised by delivery by the Company of written notice
to the Selling Founder and the Secretary of the Company.


 



    	- 21 -



    	 



    

 


(b)          The
closing of the purchase of the Offered Shares pursuant to this Section 5 shall take place at the offices of the Company on
the ROFR Purchase Date. At such closing, the Selling Founder shall convey record and beneficial ownership of the Offered Shares
to the Company in at a time and place specified by the Company by delivering certificates representing the Offered Shares so purchased,
duly endorsed for transfer or accompanied by duly and validly executed stock powers endorsed in blank.


 


(c)          In
the event that the Company fails to exercise the Company ROFR during the Company ROFR Period, the Company shall be deemed to have
rejected its right to exercise the Company ROFR.


 


(d)          To
the extent that the consideration proposed to be paid by the Offeror for the Offered Shares consists of consideration other than
cash, the consideration required to be paid by the Company and/or the New Investors exercising their rights of first refusal and
options under Sections 5.4 and 5.5 hereof may consist of cash equal to the value of such property, as determined in good faith
by agreement of the Selling Founder and the Company and/or the New Investors, as applicable, acquiring such Offered Shares.


 


5.6          Co-Sale
Rights; Failure to Exercise.


 


(a)          To
the extent that all of the Offered Shares were not purchased pursuant to the provisions of Sections 5.4 and 5.5, a New Investor,
if it has, pursuant to Section 5.4(a) expressed a desire to sell Participating Shares shall be entitled to do so pursuant
to this Section 5.6. The Company shall on the ROFR Purchase Date notify the Selling Founder of the aggregate number of Participating
Shares such New Investors wish to sell. The Selling Founder shall use his reasonable best efforts to cause the Offeror to purchase,
in addition to any Offered Shares less any Offered Shares being purchased by the New Investors and the Company pursuant to the
provisions of Section 5.4 and 5.5 (the “Co-Sale Shares”), the Participating Shares that a New Investor
wishes to sell. If the Offeror does not wish to purchase all of the Co-Sale Shares and the Participating Shares, then such New
Investor and the Selling Founder shall be entitled to sell, at the price and on the terms and conditions set forth in the Founder
Notice, a portion of such Co-Sale Shares and Participating Shares being sold to the Offeror, in the same proportion as such Selling
Founder or New Investor’s ownership of Shares bears to the aggregate number of Shares owned by the Selling Founder and such
New Investor. The transaction contemplated by the Founder Notice shall be consummated not later than 60 days after the expiration
of the Investor ROFR Period.


 


(b)          If
neither the rights of first refusal under Section 5.4 and 5.5 nor the co-sale rights under Section 5.6(a) have been exercised
by the Company or the New Investors (subject to the Selling Founders compliance with the terms of this Agreement), then the Selling
Founder shall be entitled, for a period of 60 days (the “Transfer Period”) beginning on the earlier of (i) the
date the Selling Founder shall have received written notice from the New Investors and the Company stating that they do not intend
to exercise their rights of first refusal or (ii) the expiration of the Company ROFR Period, if the Company shall have not provided
any notice exercising the Company ROFR to Transfer, all (but not less than all) of the Final Remaining Shares upon the terms set
forth in the Founder Notice. If the Selling Founder shall not have Transferred all of the Offered Shares for any reason before
the expiration of the Transfer Period, then no Transfer subject to this Section 5 (including Transfers of any Shares that
were previously deemed Offered Shares) by such Selling Founder thereafter shall be consummated unless all of the provisions of
this Section 5 are again complied with.

5.7          Special
Co-Sale.


 


(a)          Offer
of Sale; Notice of Proposed Sale. If Genextra desires to consummate a Genextra Transfer, in a single transaction or series
of transactions, that would, when taken together with all prior Genextra Transfers, constitute a Change of Control (the “Genextra
Sale”), then Genextra shall first deliver written notice of their desire to do so (the “Genextra Notice”)
to the Company and OrbiMed, in the manner prescribed by Section 9(d) of this Agreement. The Genextra Notice must specify:
(i) the name and address of the party to which Genextra proposes to sell or otherwise dispose of the Shares or an interest
in the Shares (the “Genextra Offeror”), (ii) the number of Shares Genextra proposes to sell or otherwise
dispose of (the “Genextra Offered Shares”), (iii) the consideration per Share to be delivered to Genextra
for the proposed sale, transfer or disposition, and (iv) all other material terms and conditions of the proposed transaction.


 


(b)         OrbiMed
Co-Sale Rights; Failure to Exercise.


 


i.            Within
ten (10) business days of the receipt by OrbiMed of the Genextra Notice, OrbiMed shall inform Genextra of its desire to participate
in the sale of the Genextra Offered Shares in the terms set forth in the Genextra Notice and the number of Shares that OrbiMed
wishes to sell (the “OrbiMed Participating Shares”). Genextra shall use its reasonable best efforts to cause
the Genextra Offeror to purchase, in addition to any Genextra Offered Shares, the OrbiMed Participating Shares that OrbiMed wishes
to sell. If the Genextra Offeror does not wish to purchase all of the Genextra Offered Shares and the OrbiMed Participating Shares,
then OrbiMed and Genextra shall be entitled to sell, at the price and on the terms and conditions set forth in the Genextra Notice,
a portion of such Genextra Offered Shares and OrbiMed Participating Shares being sold to the Genextra Offeror, in the same proportion
as Genextra’s or OrbiMed’s ownership of Shares bears to the aggregate number of Shares owned by Genextra and OrbiMed
collectively. The transaction contemplated by the Genextra Notice shall be consummated not later than 60 days after the date of
the Genextra Notice.


 


ii.         If
the co-sale rights under Section 5.7(b)(i) have not been exercised by OrbiMed (subject to Genextra’s compliance with
the terms of this Agreement), then Genextra shall be entitled, for a period of 60 days (the “Genextra Transfer Period”)
beginning on expiration of the ten (10) day period set forth in Section 5.7(b)(i) above, to consummate a Genextra Transfer, for
all (but not less than all) of the Genextra Offered Shares upon the terms set forth in the Genextra Notice or terms no more favorable
to Genextra than the terms set forth in the Genextra Notice. If Genextra shall not have transferred all of the Genextra Offered
Shares for any reason before the expiration of the Genextra Transfer Period, then no Genextra Transfer subject to this Section 5.7
by Genextra thereafter shall be consummated unless all of the provisions of this Section 5.7 are again complied with.


 


(c)       Limitations.
In order for Genextra to consummate a Genextra Sale, such transaction must provide that:


 


i.     any
liability shall be limited to such participating Stockholder's applicable share (determined based on the respective proceeds payable
to each participating Stockholder in connection with such Genextra Sale) of a negotiated aggregate indemnification amount that
applies equally to all participating Stockholders but that in no event exceeds the amount of consideration otherwise payable to
such Stockholder in connection with such Genextra Sale, except with respect to claims related to fraud by such Stockholder, the
liability for which need not be limited as to such Stockholder; and


 



    	- 23 -



    	 



    

 


ii.     the
consideration to be received by OrbiMed shall be in the same form and per Share amount as that received by Genextra and any other
participants in the Genextra Sale, with the per Share amount calculated as if any share of Preferred Stock transferred in the Genextra
Sale was converted into Common Stock pursuant to Restated Certificate.


 


5.8          Termination.


 


(a)          All
of the rights and obligations under this Section 5 shall terminate in their entirety on the earliest to occur of (i) immediately
prior to a Qualified IPO, (ii) a Trading Event, or (iii) the sale of all or substantially all of the assets or business
of the Company, by merger, sale of assets or otherwise.

provisions of Sections 5.3, 5.4, 5.5, 5.6 and 5.7 hereof shall not apply to any sale of Shares pursuant to a transaction referred
to in Section 5.8(a) above.


 


5.9          Transfers
of Rights. The rights and obligations of each Stockholder under this Section 5 may be assigned by such Stockholder to
any person or entity to which Shares are transferred by such Stockholder, or to any partner, stockholder or affiliate of such Stockholder,
and such transferee shall be deemed a “Stockholder” for purposes of this Agreement; provided that the transferee
provides written notice of such assignment to the Company and agrees in writing to be bound hereby.


 


6.            Preemption
Right.


 


6.1          Rights
of Stockholders.


 


(a)          Subject
to Section 6.1(g) and Section 6.2, the Company shall not issue, sell or exchange, agree to issue, sell or exchange, or reserve
or set aside for issuance, sale or exchange (i) any shares of its Common Stock, (ii) any other equity securities of the
Company, including, without limitation, shares of preferred stock, (iii) any option, warrant or other right to subscribe for,
purchase or otherwise acquire any equity securities of the Company or (iv) any debt securities convertible into capital stock
of the Company (collectively, the “Offered Securities”), unless in each such case the Company shall have first
complied with this Section 6.1. The Company shall deliver to each Stockholder that is the then registered and beneficial owner
of not less than 1,000,000 shares of Series A Stock, Series B Stock, Series C Stock or Common Stock (subject to appropriate adjustment
for stock splits, stock dividends, recapitalizations and similar events occurring after the date of this Agreement), who is also
an accredited investor (as such term is defined in the rules and regulations promulgated under the Securities Act) (each, a “Qualified
Holder”) a written notice of any proposed or intended issuance, sale or exchange of Offered Securities (the “Preemption
Offer”), which written notice shall (i) identify and describe the Offered Securities, (ii) describe the price
and other terms upon which they are to be issued, sold or exchanged, and the number or amount of the Offered Securities to be issued,
sold or exchanged, (iii) identify the persons or entities (if known) to which or with which the Offered Securities are to
be offered, issued, sold or exchanged and (iv) offer to issue and sell to or exchange with such Qualified Holder (A) a
pro rata portion of the Offered Securities determined by multiplying (x) the number of Offered Securities by (y) a
fraction, the numerator of which shall be the aggregate number of Shares then held by such Qualified Holder and the denominator
of which shall be the total number of Shares held by all Qualified Holders treating all options, warrants or securities exercisable
or convertible into Shares that are held by all Qualified Holders (other than such options, warrants or securities held by such
Qualified Holder) as exercised or converted (the “Basic Amount”), and (B) any additional portion of the
Offered Securities attributable to the Basic Amounts of other Qualified Holders as such Qualified Holder shall indicate it will
purchase or acquire should the other Qualified Holders subscribe for less than their Basic Amounts (the “Undersubscription
Amount”).


 



    	- 24 -



    	 



    

 


(b)          To
accept a Preemption Offer, in whole or in part, a Qualified Holder must deliver a written notice to the Company prior to 20 business
days after the date of delivery of the Preemption Offer, setting forth the portion of the Qualified Holder’s Basic Amount
that such Qualified Holder elects to purchase and, if such Qualified Holder shall elect to purchase all of its Basic Amount, the
Undersubscription Amount (if any) that such Qualified Holder elects to purchase (the “Notice of Acceptance”).
In the event that any Qualified Holder fails deliver a Notice of Acceptance in such 20 business day period, such Qualified
Holder shall be deemed to have rejected its right to accept the Preemption Offer. If the Basic Amounts subscribed for by all Qualified
Holders are less than the total of all of the Basic Amounts available for purchase, then each Qualified Holder who has set forth
an Undersubscription Amount in its Notice of Acceptance shall be entitled to purchase, in addition to the Basic Amounts subscribed
for, the Undersubscription Amount it has subscribed for; provided, however, that if the Undersubscription Amounts
subscribed for exceed the difference between the total of all of the Basic Amounts available for purchase and the Basic Amounts
subscribed for (the “Available Undersubscription Amount”), each Qualified Holder who has subscribed for any
Undersubscription Amount shall be entitled to purchase only that portion of the Available Undersubscription Amount as the Undersubscription
Amount subscribed for by such Qualified Holder bears to the total Undersubscription Amounts subscribed for by all Qualified Holders,
rounded down to the nearest whole number.


 


(c)          The
Company shall have 120 days from the expiration of the period set forth in Section 6.1(b) above to issue, sell or exchange
all or any part of such Offered Securities as to which a Notice of Acceptance has not been given by the Qualified Holders (the
“Refused Securities”), but only to the offerees or purchasers described in the Preemption Offer (if so described
therein) and only upon terms and conditions (including, without limitation, unit prices and interest rates) which are not more
favorable, in the aggregate, to the acquiring person or persons or less favorable to the Company than those set forth in the Preemption
Offer. Notwithstanding anything contained herein to the contrary, the closing of the purchase of Shares pursuant to a Preemption
Offer shall take place no later than 20 business days from the date of receipt of a Notice of Acceptance.


 


(d)          In
the event the Company shall propose to sell less than all the Refused Securities (any such sale to be in the manner and on the
terms specified in Section 6.1(c) above), then each Qualified Holder may, at its sole option and in its sole discretion, reduce
the number or amount of the Offered Securities specified in its Notice of Acceptance to an amount that shall be not less than the
number or amount of the Offered Securities that the Qualified Holder elected to purchase pursuant to Section 6.1(b) above
multiplied by a fraction, (i) the numerator of which shall be the number or amount of Offered Securities the Company actually
proposes to issue, sell or exchange (including Offered Securities to be issued or sold to Qualified Holders pursuant to Section 6.1(b)
above prior to such reduction) and (ii) the denominator of which shall be the original amount of the Offered Securities. In
the event that any Qualified Holder so elects to reduce the number or amount of Offered Securities specified in its Notice of Acceptance,
the Company may not issue, sell or exchange more than the reduced number or amount of the Offered Securities unless and until such
securities have again been offered to the Qualified Holders in accordance with Section 6.1(a) above.


 



    	- 25 -



    	 



    

 


(e)          Upon
the closing of the issuance, sale or exchange of all or less than all of the Refused Securities, the Qualified Holders shall acquire
from the Company, and the Company shall issue to the Qualified Holders, the number or amount of Offered Securities specified in
the Notices of Acceptance, as reduced pursuant to Section 6.1(d) above if the Qualified Holders have so elected, upon the
terms and conditions specified in the Preemption Offer. The purchase by the Qualified Holders of any Offered Securities is subject
in all cases to the preparation, execution and delivery by the Company and the Qualified Holders of a purchase agreement relating
to such Offered Securities reasonably satisfactory in form and substance to the Qualified Holders and their respective counsel.


 


(f)          Any
Offered Securities not acquired by the Qualified Holders or other persons in accordance with Section 6.1(c) above may not
be issued, sold or exchanged until they are again offered to the Qualified Holders under the procedures specified in this Agreement.


 


(g)          The
rights of the Qualified Holders under this Section 6 shall not apply to:


 


(1)         the
issuance of any shares of Common Stock, Option or Convertible Securities as a stock dividend to holders of Common Stock, Series
A Stock, Series B Stock or Series C Stock or upon any subdivision or combination of shares of Common Stock, Series A Stock, Series
B Stock or Series C Stock;


 


(2)         the
issuance of shares of Series C Stock pursuant to the Series C Preferred Stock Purchase Agreement;

of Common Stock or Convertible Securities actually issued upon the exercise of Options or shares of Common Stock actually issued
upon the conversion or exchange of Convertible Securities, in each case provided such issuance is pursuant to the terms of such

of Common Stock, Options or Convertible Securities issued to banks, equipment lessors or other financial institutions, or to real
property lessors, pursuant to a debt financing, equipment leasing or real property leasing transaction approved by the Board;


 


(7)         shares
of Common Stock, Options or Convertible Securities issued to suppliers or third party service providers in connection with the
provision of goods or services pursuant to transactions approved by the Board of Directors of the Company;


 


(8)         shares
of Common Stock, Options or Convertible Securities issued pursuant to the acquisition of another corporation by the Corporation
by merger, purchase of substantially all of the assets or other reorganization or to a joint venture agreement, provided,
that such issuances are approved by the Board; or


 



    	- 26 -



    	 



    

 


(9)         shares
of Common Stock, Options or Convertible Securities issued in connection with sponsored research, collaboration, technology license,
development, OEM, marketing or other similar agreements or strategic partnerships approved by the Board.


 


6.2          Termination.


 


(a)          All
of the rights and obligations under this Section 6 shall terminate in their entirety on the earliest of (i) immediately

Any party may give
any notice, request, consent or other communication under this Agreement using any other means (including personal delivery, messenger
service, first class mail or electronic mail), but no such notice, request, consent or other communication shall be deemed to have
been duly given unless and until it is actually received by the party for whom it is intended. Any party may change the address
to which notices, requests, consents or other communications hereunder are to be delivered by giving the other parties notice in
the manner set forth in this Section 9(d).


 


(e)          Complete
Agreement. This Agreement constitutes the entire agreement and understanding of the parties hereto with respect to the subject
matter hereof. The Prior Agreement is hereby amended and restated and superseded in all respects by this Agreement.


 


(f)          Amendments
and Waivers. This Agreement may be amended or terminated and the observance of any term of this Agreement may be waived with
respect to all parties to this Agreement (either generally or in a particular instance and either retroactively or prospectively),
with the written consent of (i) the Company, (ii) the Founders holding Shares representing a majority of the Shares then
held by all of the Founders and (iii) the Requisite Holders; provided that any amendment, termination or waiver to
the terms of Section 2 (or a defined term used therein) that occurs after the closing of the Initial Public Offering shall
instead require the written consent of (X) the Company, (Y) the Founders holding Registrable Shares representing a majority
of the Registrable Shares then held by all of the Founders and (Z) the Holders holding Registrable Shares representing a majority
of all of the Registrable Shares then held by all of the Holders; and provided further, that any amendment, termination
or waiver to the definition of Major Holder shall require the affirmative consent of each Major Holder. Notwithstanding the foregoing,
this Agreement may not be amended or terminated and the observance of any term hereunder may not be waived with respect to any
Stockholder without the written consent of such Stockholder unless such amendment, termination or waiver applies to all Stockholders
in the same fashion (it being agreed that a waiver of the provisions of Section 5 or Section 6 with respect to a particular
transaction shall be deemed to apply to all Stockholders in the same fashion if such waiver does so by its terms, notwithstanding
the fact that certain Stockholders may nonetheless, by agreement with the Company, purchase securities in such transaction). The
Company shall give prompt written notice of any amendment or termination hereof or waiver hereunder to any party hereto that did
not consent in writing to such amendment, termination or waiver. Any amendment, termination or waiver effected in accordance with
this Section 9(f) shall be binding on all parties hereto, even if they do not execute such consent. No waivers of or exceptions
to any term, condition or provision of this Agreement, in any one or more instances, shall be deemed to be, or construed as, a
further or continuing waiver of any such term, condition or provision. In addition, to the extent that any change to any ownership
threshold specified in this Agreement relating to any rights of any Stockholder under this Agreement, or any new threshold relating
to any rights of any Stockholder under this Agreement is imposed, which causes a Stockholder to lose such rights, then such change
shall not be effective with respect to such Stockholder unless the written instrument effecting such change is signed by such Stockholder.

forms, and the singular form of nouns and pronouns shall include the plural, and vice versa.

Facsimile Signatures. This Agreement may be executed in any number of counterparts, each of which shall be deemed to be an
original, and all of which together shall constitute one and the same document. This Agreement may be executed by facsimile signatures.

Headings. The section headings are for the convenience of the parties and in no way alter, modify, amend, limit or restrict
the contractual obligations of the parties.
