ARTICLE III -
RESTRICTIONS ON TRANSFER; RIGHT OF REFUSAL; CO-SALE PROVISIONS

 

The following provisions
of this Article III shall terminate immediately upon, and shall not apply with respect to, a QPO.

 

Section 3.1                    
Restrictions on Transfer. Each Other Stockholder agrees that such Other Stockholder will not, without the
prior written consent of a Majority Interest, Transfer all or any portion of the Shares now owned or hereafter acquired by such
Other Stockholder, except in connection with, and strictly in compliance with the conditions of this Article III. No Stockholder
shall be a party to any a transaction or series of related transactions in which a Person, or a group of related Persons, acquires
from stockholders of the Company shares representing more than fifty percent (50%) of the outstanding voting power of the Company
(a “Stock Sale”) unless all holders of Preferred Stock are allowed to participate in such transaction and the
consideration received pursuant to such transaction is allocated among the parties thereto in the manner specified in the Company’s
Charter in effect immediately prior to the Stock Sale (as if such transaction were a Liquidation Event (as such term is defined
in the Charter)), unless the holders of at least a Majority Interest elect otherwise by written notice given to the Company at
least 5 days prior to the effective date of any such transaction or series of related transactions.

 

Section 3.2                     
Permitted Transfers. Notwithstanding anything herein to the contrary, the provisions of Sections 3.3
and 3.4 shall not apply to either of the Transfers listed below (each such transferee, a “Permitted Transferee”),
provided that in each case the Transferee shall have entered into a Joinder Agreement in substantially the form attached
hereto as Exhibit A providing that all Shares so Transferred shall continue to be subject to all provisions of this Agreement
as if such Shares were still held by such Other Stockholder, except that no further Transfer shall thereafter be permitted hereunder
except in compliance with Sections 3.3 and 3.4:

 

(a)               
Transfers by any Other Stockholder to the ancestors, spouse, or children of such Other Stockholder or to a trust or family
limited partnership for the benefit of any of them; and

 

(b)               
Transfers upon the death of any Other Stockholder to such Other Stockholder’s heirs, executors or administrators or
to a trust under such Other Stockholder’s will, or Transfers between such Other Stockholder and such Other Stockholder’s
guardian or conservator.

 

Notwithstanding the foregoing, no party
hereto shall avoid the provisions of this Agreement by (i) making one or more Transfers to one or more Permitted Transferees and
then disposing of all or any portion of such party’s interest in any such Permitted Transferee or (ii) by Transferring the
securities of any entity holding Shares directly or indirectly. Notwithstanding anything to the contrary in this Agreement or any
failure by a Transferee under this Section 3.2 to execute a Joinder Agreement, such Transferee shall take any Shares so
Transferred subject to all provisions of this Agreement as if such Shares were still held by the Other Stockholder making such
Transfer, whether or not they so agree in writing.

 

Section 3.3                    
Prohibited Transferees. Notwithstanding the foregoing, no Stockholder shall Transfer to (a) any entity which,
in the determination of the Company’s Board of Directors, directly or indirectly competes with the Company; or (b) any customer,
distributor or supplier of the Company, if the Company’s Board of Directors should determine that such transfer would result
in such customer, distributor or supplier receiving information that would place the Company at a competitive disadvantage with
respect to such customer, distributor or supplier. Notwithstanding anything to the contrary herein SAEV may Transfer to SAEV Guernsey
Holdings Limited and Schlumberger may Transfer to a U.S. Schlumberger Affiliate (provided that at the time of the proposed Transfer
by SAEV or Schlumberger either (i) the transferee is not an entity which, in the determination of the Board of Directors, directly
or indirectly competes with the Company, or (ii) the transferor represents in writing to the Company that the transferee is a non-operating
entity) at any time without the prior consent of any Person by following the transfer procedures set forth in Section 3.2
above.

 

    - 5 -

     

    

 

Section 3.4                     
Right of First Refusal. In the event that any of the Other Stockholders entertains a bona fide offer to purchase
all or any portion of the Shares (other than shares of Preferred Stock) held by such Other Stockholder (a “Transaction
Offer”) from any other Person (a “Buyer”), such Other Stockholder (a “Transferring Stockholder”)
may, subject to the provisions of Section 3.4 hereof, Transfer such Shares pursuant to and in accordance with the following
provisions of this Section 3.3:

 

(a)               
Offer Notice. The Transferring Stockholder shall cause the Transaction Offer and all of the terms thereof
to be reduced to writing and shall promptly notify the Company and each of the Investors and Founders of such Transferring Stockholder’s
desire to effect the Transaction Offer and otherwise comply with the provisions of this Section 3.3 and, if applicable,
Section 3.4 (such notice, the “Offer Notice”). The Transferring Stockholder’s Offer Notice shall
constitute an irrevocable offer to sell all but not less than all of the Shares which are the subject of the Transaction Offer
(the “Offered Shares”) to the Company, the Investors and the Founders, on the basis described below, at a purchase
price equal to the price contained in, and on the same terms and conditions of, the Transaction Offer. The Offer Notice shall be
accompanied by a true copy of the Transaction Offer (which shall identify the Buyer and all relevant information in connection
therewith).

 

(b)               
Company Option. The Company shall have the first option to purchase all or a portion of the Offered Shares.
At any time within twenty (20) days after receipt by the Company of the Offer Notice (the “Company Option Period”),
the Company may elect to accept the offer to purchase with respect to any or all of the Offered Shares and shall give written notice
of such election (the “Company Acceptance Notice”) to the Transferring Stockholder within the Company Option
Period, which notice shall indicate the number of Offered Shares that the Company is willing to purchase. The Company Acceptance
Notice shall constitute a valid, legally binding and enforceable agreement for the sale and purchase of the Offered Shares covered
by the Company Acceptance Notice. If the Company accepts the offer to purchase all of the Offered Shares, the closing for such
purchase of the Offered Shares by the Company under this Section 3.4(b) shall take place within thirty (30) days following
the expiration of the Company Option Period, at the offices of the Company or on such other date or at such other place as may
be agreed to by the Transferring Stockholder and the Company. If the Company fails to purchase all of the Offered Shares by exercising
its option under this Section 3.4(b) within the Company Option Period and such 30 day period, the Transferring Stockholder
shall so notify the Investors and Founders promptly (the “Additional Offer Notice”), which Additional Offer
Notice shall identify the Offered Shares that the Company has failed to purchase (the “Remaining Shares”). The
Remaining Shares shall be subject to the options granted to the Investors and Founders pursuant to Section 3.4(c) below.

 

(c)               
Investors’ and Founders’ Option. If the Company fails to purchase all of the Offered Shares under
Section 3.4(b) above, at any time within thirty (30) days after receipt by the Investors and Founders of the Additional
Offer Notice (the “Investor/Founder Option Period”), each Investor and Founder (other than the Transferring
Stockholder, if applicable) may elect to accept the offer to purchase with respect to any or all of the Remaining Shares and shall
give written notice of such election (the “Investor/Founder Acceptance Notice”) to the Transferring Stockholder
and each Investor and Founder within the Investor/Founder Option Period, which notice shall indicate the maximum number of Shares
that the Investor or Founder, as applicable, is willing to purchase, including the number of Remaining Shares it would purchase
if one or more other Investors and Founders do not elect to purchase their Pro Rata Fractions (as defined in paragraph (d) below).
The Investor/Founder Acceptance Notice shall constitute a valid, legally binding and enforceable agreement for the sale and purchase
of the Remaining Shares covered by the Investor/Founder Acceptance Notice. The closing for any purchase of Remaining Shares by
the Investors and Founders under this Section 3.4(c) (along with the purchase by the Company of any Offered Shares under
paragraph (b) above if the Company is purchasing less than all of the Offered Shares) shall take place within thirty (30) days
following the expiration of the Investor/Founder Option Period, at the offices of the Company or on such other date or at such
other place as may be agreed to by the Transferring Stockholder and such Investors. The Transferring Stockholder shall notify the
Investors and Founders promptly if any Investor or Founder fails to offer to purchase all of its Pro Rata Fraction.

 

    - 6 -

     

    

 

(d)               
Allocation of Remaining Shares among Investors and Founders. Upon the expiration of the Investor/Founder Option
Period, the number of Remaining Shares to be purchased by each Investor and Founder shall be determined as follows: (i) first,
there shall be allocated to each Investor and Founder electing to purchase, a number of Remaining Shares equal to the lesser of
(A) the number of Remaining Shares as to which such Investor or Founder, as applicable, accepted as set forth in its respective
Investor/Founder Acceptance Notice or (B) such Investor’s or Founder’s Pro Rata Fraction of the Remaining Shares (as
defined below), and (ii) second, the balance, if any, not allocated under clause (i) above, shall be allocated to those Investors
who within the Investor/Founder Option Period delivered an Investor/Founder Acceptance Notice that set forth a number of Remaining
Shares that exceeded their respective Pro Rata Fractions, in each case on a pro rata basis in proportion to the number of Shares
held by each such Investor up to the amount of such excess. An Investor’s or Founder’s “Pro Rata Fraction”
shall be equal to the product obtained by multiplying the total number of Remaining Shares by a fraction, the numerator of which
is the total number of Shares owned by such Investor or Founder, and the denominator of which is the total number of Shares
held by all Investors and Founders (other than the Transferring Stockholder, if applicable), in each case as of the date of the
Offer Notice.

 

(e)               
Valuation of Property. In the event that the price set forth in the Offer Notice is stated in consideration
other than cash or cash equivalents, the Transferring Stockholder, the Company and a Majority Interest shall mutually determine
the fair market value of such consideration, reasonably and in good faith, and the Company and/or the Investors or Founders, as
the case may be, may effect their purchase under this Section 3.4 by payment of such fair market value in cash or cash equivalents.

 

(f)                
Sale to Third Party. In the event that the Company, the Investors and the Founders do not elect to exercise
the rights to purchase under this Section 3.4 with respect to all of the Shares proposed to be sold, the Transferring Stockholder
may sell any remaining Shares to the Buyer on the terms and conditions set forth in the Offer Notice, subject to the provisions
of Section 3.5. Promptly after such Transfer, the Transferring Stockholder shall notify the Company, which in turn shall
promptly notify all the Investors and Founders, of the consummation thereof and shall furnish such evidence of the completion and
time of completion of the Transfer and of the terms thereof as may reasonably be requested by a Majority Interest. Prior to the
effectiveness of any Transfer to a Buyer hereunder, such Buyer shall have entered into a Joinder Agreement in substantially the
form attached hereto as Exhibit A, and such Buyer shall have all the rights and obligations hereunder as if such Buyer were
an Other Stockholder. If the Transferring Stockholder’s sale to a Buyer is not consummated in accordance with the terms of

(g)               
Assignment of Rights The Company hereby irrevocably assigns to the Investors all rights of first refusal the
Company may have pursuant to any agreement with any holder of equity securities of the Company with respect to any shares of Common
Stock of the Company not purchased by the Company pursuant to such rights of first refusal, to be allocated among the Investors
in accordance with this Section 3.4.

 

Section 3.5                      
Co-Sale Option of Investors. In the event that the Company, the Investors and the Founders do not exercise
their rights under Section 3.4 with respect to all of the Shares proposed to be so Transferred in connection with any Transaction
Offer, the Transferring Stockholder may Transfer such Shares only pursuant to and in accordance with the following provisions of
this Section 3.5:

 

(a)               
Co-Sale Notice. As soon as practicable following the expiration of the Investor/Founder Option Period, and
in no event later than five (5) days thereafter, the Transferring Stockholder shall provide notice to each of the Investors (the
 “Co-Sale Notice”) of its right to participate in the Transaction Offer on a pro rata basis with the Transferring
Stockholder (the “Co-Sale Option”). To the extent one or more Investors exercise their Co-Sale Option in accordance
with this Section 3.4, the number of Shares that the Transferring Stockholder may Transfer in the Transaction Offer shall
be correspondingly reduced.

 

(b)               
Investor Acceptance. Each of the Investors shall have the right to exercise its Co-Sale Option by giving written
notice of such intent to participate (the “Co-Sale Acceptance Notice”) to the Transferring Stockholder within
ten (10) days after receipt by such Investor of the Co-Sale Notice (the “Co-Sale Election Period”). Each Co-Sale
Acceptance Notice shall indicate the maximum number of Shares subject thereto which the Investor wishes to sell, including the
number of Shares it would sell if one or more other Investors do not elect to participate in the sale on the terms and conditions
stated in the Offer Notice. Any Investor holding Preferred Stock shall be permitted to sell to the relevant Buyer in connection
with any exercise of the Co-Sale Option, at its option, (i) shares of Common Stock acquired upon conversion of such Preferred Stock
or (ii) shares of Preferred Stock giving effect to the relative preferences and value of the Preferred Stock and the Common Stock.

 

(c)               
Allocation of Shares. Each Investor shall have the right to sell a portion of its Shares pursuant to the Transaction
Offer which is equal to or less than the product obtained by multiplying the total number of Shares available for sale to the Buyer
subject to the Transaction Offer by a fraction, the numerator of which is the total number of Shares owned by such Investor
and the denominator of which is the total number of Shares held by all Investors and the Transferring Stockholder, in each
case as of the date of the Offer Notice, subject to increase as hereinafter provided. In the event any Investor does not elect
to sell the full amount of such Shares which such Investor is entitled to sell pursuant to this Section 3.5, then any Investors
who have elected to sell Shares shall have the right to sell, on a pro-rata basis (based on the number of Shares held by each such
Investor) with any other Investors who have delivered a Co-Sale Acceptance Notice and up to the maximum number of Shares stated
in each such Investor’s Co-Sale Acceptance Notice, any Shares not elected to be sold by such Investor.

(d)               
Co-Sale Closing. Within ten (10) calendar days after the end of the Co-Sale Election Period, the Transferring
Stockholder shall promptly notify each participating Investor of the number of Shares held by such Investor that will be included
in the sale and the date on which the Transaction Offer will be consummated, which shall be no later than the later of (i) thirty
(30) calendar days after the end of the Co-Sale Election Period and (ii) the satisfaction of any governmental approval or filing
requirements, if any. Each participating Investor may effect its participation in any Transaction Offer hereunder by delivery to
the Buyer, or to the Transferring Stockholder for delivery to the Buyer, of one or more instruments or certificates, properly endorsed
for transfer, representing the Shares it elects to sell pursuant thereto. At the time of consummation of the Transaction Offer,
the Buyer shall remit directly to each participating Investor that portion of the sale proceeds to which the participating Investor
is entitled by reason of its participation with respect thereto. No Shares may be purchased by the Buyer from the Transferring
Stockholder unless the Buyer simultaneously purchases from the participating Investors all of the Shares that they have elected
to sell pursuant to this Section 3.5.

 

(e)               
Liability of Investors. Each participating Investor shall be liable to the Buyer only to same extent as the
Transferring Stockholder with respect to representations and warranties regarding the Company or its business, on a several basis
for each such participating Investor’s pro rata portion, provided that each such Investor’s liability with respect
to such representations and warranties shall not exceed the value of the proceeds received by such Investor upon the consummation
of the Transaction Offer.

 

(f)                
Sale to Third Party. Any Shares held by a Transferring Stockholder that are the subject of the Transaction
Offer and that the Transferring Stockholder desires to Transfer following compliance with this Section 3.5, may be sold
to the Buyer only during the period specified in Section 3.4(f) and only on terms no more favorable to the Transferring
Stockholder than those contained in the Offer Notice. Promptly after such Transfer, the Transferring Stockholder shall notify the
Company, which in turn shall promptly notify all the Investors, of the consummation thereof and shall furnish such evidence of
the completion and time of completion of the Transfer and of the terms thereof as may reasonably be requested by a Majority Interest.
Prior to the effectiveness of any Transfer to a Buyer hereunder, such Buyer shall have entered into a Joinder Agreement in substantially
the form attached hereto as Exhibit A, and such Buyer shall have all the rights and obligations hereunder as if such Buyer
were an Other Stockholder. In the event that the Transaction Offer is not consummated within the period required by this Section
3.5 or the Buyer fails timely to remit to each participating Investor its respective portion of the sale proceeds, the Transaction
Offer shall be deemed to lapse, and any Transfer of Shares pursuant to such Transaction Offer shall be in violation of the provisions
of this Agreement unless the Transferring Stockholder sends a new Offer Notice and once again complies with the provisions of Sections
3.4 and 3.5 with respect to such Transaction Offer.

 

Section 3.6                      
Contemporaneous Transfers. If two or more Other Stockholders propose concurrent Transfers that are subject
to this Article III, then the relevant provisions of Sections 3.4 and 3.5, as applicable, shall apply separately
to each such proposed Transfer.

 

Section 3.7                      
Assignment. Subject to Section 8.11 hereof, each Investor shall have the right to assign its rights
hereunder to any Transferee of such Investor’s Shares, and shall further have the right to assign and transfer such Investor’s
right to accept any particular Transaction Offer, and any such Transferee shall be deemed within the definition of an “Investor”
for purposes of this Article III.

 

    - 9 -

     

    

 

Section 3.8                     
Effect of Prohibited Transfers. If any Transfer is made or attempted contrary to the provisions of this Agreement,
such purported Transfer shall be void ab initio; the Company and the other parties hereto shall have, in addition to any
other legal or equitable remedies which they may have, the right to enforce the provisions of this Agreement by actions for specific
performance (to the extent permitted by law); and the Company shall have the right to refuse to recognize any Transferee as one
of its Stockholders for any purpose.

 

ARTICLE IV - RIGHTS TO PURCHASE

 

The following provisions
of this Article IV shall terminate immediately upon, and shall not apply with respect to, a QPO.

 

Section 4.1                      
Right to Participate in Certain Sales of Additional Securities. The Company agrees that it will not sell or
issue: (a) any shares of capital stock of the Company, (b) securities convertible into or exercisable or exchangeable for capital
stock of the Company or (c) options, warrants or rights carrying any rights to purchase capital stock of the Company, unless the
Company first submits a written notice to each Investor identifying the terms of the proposed sale (including price, number or
aggregate principal amount of securities and all other material terms), and offers to each Investor the opportunity to purchase
its Pro Rata Allotment (as hereinafter defined) of the securities (subject to increase for over allotment if some Investors do
not fully exercise their rights) on terms and conditions, including price, not less favorable than those on which the Company proposes
to sell such securities to a third party or parties. The Company’s offer pursuant to this Section 4.1 shall remain
open and irrevocable for a period of twenty (20) days following receipt by the Investors of such written notice (the “Right
of First Offer Period”).

 

Section 4.2                     
Investor Acceptance. Each Investor may elect to purchase the securities so offered by giving written notice
thereof to the Company within the Right of First Offer Period, including in such written notice the maximum number of shares of
capital stock or other securities of the Company that the Investor wishes to purchase, including the number of such shares it would
purchase if one or more other Investors do not elect to purchase their respective Pro Rata Allotments.

 

Section 4.3                      
Calculation of Pro Rata Allotment. Each Investor’s “Pro Rata Allotment” of such securities
shall be based on the ratio which the number of Shares owned by such Investor bears to all of the issued and outstanding Shares
as of the date of such written offer. If one or more Investors do not elect to purchase their respective Pro Rata Allotment, each
of the electing Investors may purchase such shares on a pro rata basis, based upon the relative holdings of Shares of each of the
electing Investors in the case of over subscription.

 

Section 4.4                      
Sale to Third Party. Any securities so offered that are not purchased by the Investors pursuant to the offer
set forth in Section 4.1 above, may be sold by the Company, but only on terms and conditions not more favorable than those
set forth in the notice to Investors, at any time within sixty (60) calendar days following the termination of the Right of First
Offer Period, but may not be sold to any other Person or on terms and conditions, including price, that are more favorable to the
purchaser than those set forth in such offer or on any terms after the expiration of such 60 day period without renewed compliance
with this Article IV.

 

Section 4.5                      
Subsequent Sale. Notwithstanding anything to the contrary in this Article IV, the Company shall
be permitted, with the prior written consent of a Majority Interest, to issue any securities without complying with the provisions
of this Article IV so long as (i) the Company gives prompt written notice to the Investors, which notice shall describe
in reasonable detail the securities being issued and the issue price thereof and (ii) the Company takes all steps reasonably necessary
to enable such Investors to effectively exercise their respective rights under this Article IV as promptly as reasonably
practicable after such issuance on the terms specified herein and in a manner that affords each such Investor electing to exercise
such rights all of the rights and benefits it would have received if each such Investor had purchased such securities contemporaneously
with such issuance.

Section 4.6                      
Exceptions to Pre-emptive Rights. Notwithstanding the foregoing, the right to purchase granted under this
Article IV shall be inapplicable with respect to Excluded Shares (as defined herein) and any other Shares with respect to
which the holder thereof waives in writing (or is deemed to have waived pursuant to Section 8.3) its rights pursuant to
this Article IV. “Excluded Shares” shall mean (i) shares of Common Stock upon conversion of shares of Preferred
Stock, (ii) shares of Common Stock or options therefor to directors, officers, employees or consultants of the Company in connection
with their service as directors of the Company, their employment by the Company or their retention as consultants by the Company,
in each case authorized by the Board of Directors and issued pursuant to any equity incentive plans approved by the Board of Directors,
(iii) as part of the consideration payable in the acquisition of another entity by the Company by merger, purchase of all or substantially
all of the assets of such entity, stock purchase or other reorganization of such entity, in each case as authorized by the Board
of Directors and the Majority Interest, (iv) to a bank or other financial institution (not to exceed two percent (2%) of all outstanding
securities) to secure a lending or equipment leasing transaction, in each case as authorized by the Board of Directors and the
Majority Interest, and (v) to a business partner, government laboratory or university to advance strategic business objectives,
as authorized by the Board of Directors and the Majority Interest.

Assignment of Rights. Subject to Section 8.11 hereof, each Investor shall have the right to assign
its rights under this Article IV to any Transferee of such Investor’s Shares, and shall further have the right to
assign and transfer such Investor’s right to accept any particular offer under Section 4.1 hereof, and any such Transferee
shall be deemed within the definition of an “Investor” for purposes of this Article IV.

 

ARTICLE V - RIGHTS TO SELL

 

The following provisions
of this Article V shall terminate immediately upon, and shall not apply with respect to, a QPO.

 

Section 5.1

such Sale Event) and to vote in opposition to any and all other proposals that could delay or impair the ability of the Company
to consummate such Sale Event;

 

    - 11 -

     

    

 

(b)               
if such transaction is a Stock Sale (as defined below), sell the same proportion of shares of capital stock of the Company
beneficially held by such Stockholder as is being sold by the Selling Investors to the Person to whom the Selling Investors propose
to sell their Shares, and, on the same terms and conditions as the Selling Investors;

 

(c)               
to execute and deliver all related documentation and take such other action in support of the Sale Event as shall reasonably

of such Shares, unless specifically requested to do so by the acquiror in connection with the Sale Event;

 

(e)               
to refrain from exercising any dissenters’ rights or rights of appraisal under applicable law at any time with respect
to such Sale Event; and

 

(f)                
if the consideration to be paid in exchange for the Shares pursuant to this Article V includes any securities and
due receipt thereof by any Stockholder would require under applicable law (x) the registration or qualification of such securities
or of any person as a broker or dealer or agent with respect to such securities or (y) the provision to any Stockholder of any
information other than such information as a prudent issuer would generally furnish in an offering made solely to “accredited
investors” as defined in Regulation D promulgated under the Securities Act, the Company may cause to be paid to any such
Stockholder in lieu thereof, against surrender of the Shares which would have otherwise been sold by such Stockholder, an amount

receive as of the date of the issuance of such securities in exchange for the Shares.

 

For purposes of this
Agreement, a “Sale Event” shall mean either: (a) a transaction or series of related transactions in which a
Person, or a group of related Persons, acquires from Stockholders of the Company shares representing more than fifty percent (50%)
of the outstanding voting power of the Company (a “Stock Sale”), or (b) a transaction that is or could be treated
as a Liquidation Event (as defined in the Charter).

Conditions. The obligations of the Stockholders pursuant to this Article V are subject to the satisfaction
of the following conditions:

 

(a)

in a Liquidation Event (as defined in the Charter) pursuant to, and in accordance with, the rights and preferences set forth in
Article IV, Section A.4 of the Charter as in effect immediately prior to such Sale Event (giving effect to applicable orders of
priority);

 

(b)               
if any Stockholders of a class or series are given an option as to the form and amount of consideration to be received,
all Stockholders of such class or series will be given the same option, provided, however, that nothing in
this Subsection 5.2(b) shall entitle any holder to receive any form of consideration that such holder would be ineligible
to receive as a result of such holder’s failure to satisfy any condition, requirement or limitation that is generally applicable
to the Company’s stockholders and the Company shall in no way be obligated to issue any equity to any investors who are not
 “accredited investors” as defined in Regulation D promulgated under the Securities Act;

 

    - 12 -

     

    

 

(c)

holder of a series of Preferred Stock will receive the same amount of consideration per share of such series of Preferred Stock
as is received by other holders in respect of their shares of such same series;

 

(d)               
any representations and warranties to be made by such Stockholder in connection with the Sale Event are limited to representations
and warranties as to the Stockholder, and not as to the Company, including, but not limited to, representations related to authority,

Equivalents”) held by such Stockholder and the ability to convey title to such capital stock and Stock Equivalents;

(f)                
the liability for indemnification, if any, of such Stockholder in the Sale Event and for the inaccuracy of any representations
and warranties made by the Company in connection with such Sale Event, is either (i) several and not joint with any other person,
and is pro rata in proportion to the amount received by the Stockholders in the Sale Event (which may take into account the applicable
orders of priority for distribution of funds); (ii) limited to funds contributed to an escrow in proportion to the amount received
by the Stockholders in the Sale Event (which may take into account the applicable orders of priority for distribution of funds);
or (iii) any combination of the above;

 

(g)               
liability shall be limited to the amount of consideration actually paid to such Stockholder in connection with such Sale
Event, except with respect to (i) representations and warranties of such Stockholder as to such Stockholder, and not as to the
Company, including representations and warranties related to authority, ownership of the capital stock and Stock Equivalents held
by such Stockholder and the ability to convey title to such capital stock and Stock Equivalents; (ii) any covenants made by such
Stockholder with respect to confidentiality or voting related to the Sale Event; or (iii) claims related to fraud or willful breach
by such Stockholder, the liability for which need not be limited; and

 

(h)               
if some or all of the consideration received in connection with the Sale Event is other than cash, then the valuation of
such assets shall be deemed to have a dollar value equal to the fair market value of such assets as determined in good faith by
the Board of Directors. The determination of fair market value shall be final and binding on all parties.

Section 7.19                        
Indemnification.

 

(a)               
Without limitation of any other provision of this Agreement or any agreement executed in connection herewith, the Company
agrees to defend, indemnify and hold each Investor, its respective Affiliates and direct and indirect partners (including partners
of partners and stockholders and members of partners), members, stockholders, directors, officers, employees and agents and each
person who controls any of them within the meaning of Section 15 of the Securities Act, or Section 20 of the Exchange Act (collectively,
the “Investor Indemnified Parties” and, individually, an “Investor Indemnified Party”) harmless from and
against any and all damages, liabilities, losses, Taxes, fines, penalties, reasonable costs and expenses (including, without limitation,
reasonable fees of a single counsel representing the Investor Indemnified Parties), as the same are incurred, of any kind or nature
whatsoever (whether or not arising out of third party claims and including all amounts paid in investigation, defense or settlement
of the foregoing) which may be sustained or suffered by any such Investor Indemnified Party (“Losses”), based upon,
arising out of, or by reason of any third party or governmental claims relating in any way to such Investor Indemnified Party’s
status as a security holder, creditor, director, agent, representative or controlling person of the Company or otherwise relating
to such Investor Indemnified Party’s involvement with the Company to the extent, and solely to the extent, that such Losses
are based upon, arise out of or are otherwise reasonably related to any action taken or omitted to be taken or alleged to have
been taken or omitted to have been taken by or on behalf of or through the Company or any of its subsidiaries (including, without
limitation, any and all Losses under the Securities Act, the Exchange Act or other federal or state statutory law or regulation,
at common law or otherwise, which relate directly or indirectly to the registration, purchase, sale or ownership of any securities
of the Company or to any fiduciary obligation owed with respect thereto), including, without limitation, in connection with any
third party or governmental action or claim relating to any action taken or omitted to be taken or alleged to have been taken or
omitted to have been taken by any Investor Indemnified Party as security holder, director, agent, representative or controlling
person of the Company or otherwise, alleging so called control person liability or securities law liability; provided, however,
that the Company will not be liable to the extent that such Losses arise from and are based on (A) an untrue statement or omission
or alleged untrue statement or omission in a registration statement or prospectus which is made in reliance on and in conformity
with written information furnished to the Company by or on behalf of such Investor Indemnified Party, or (B) conduct by such Investor
Indemnified Party which constitutes fraud or willful misconduct.

 

(b)               
If the indemnification provided for in Section 7.19(a) above for any reason is held by a court of competent jurisdiction
to be unavailable to an Investor Indemnified Party in respect of any Losses referred to therein, then the Company, in lieu of indemnifying
such Investor Indemnified Party thereunder, shall contribute to the amount paid or payable by such Investor Indemnified Party as
a result of such Losses (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the
Investors, or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is
appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company
and the Investors in connection with the action or inaction which resulted in such Losses, as well as any other relevant equitable
considerations. The relative fault of the Company and the Investors 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 Company and the Investors and the parties’ relative intent, knowledge, access to information
and opportunity to correct or prevent such statement or omission.

 

(c)               
Each of the Company and the Investors agrees that it would not be just and equitable if contribution pursuant to Section
7.19(b) were determined by pro rata or per capita allocation or by any other method of allocation which does not take account
of the equitable considerations referred to in the immediately preceding paragraph.

 

    - 21 -

     

    

  

Section 7.20                       
Successor Indemnification. If the Company or any of its successors or assignees consolidates with or merges
into any other Person and is not the continuing or surviving corporation or entity of such consolidation or merger, then to the
extent necessary, proper provision shall be made so that the successors and assignees of the Company assume the obligations of

whether such obligations are contained in the Company’s By-laws, the Charter, this Agreement or elsewhere, as the case may
be.

 

Section 7.21                       
Employee Stock Vesting. Unless otherwise approved by the Board of Directors, including at least two of the
Preferred Directors, all employees and consultants of the Company who purchase, receive options to purchase, or receive awards
of shares of the Company’s capital stock after the date hereof shall be required to execute restricted stock or option agreements,
as applicable, providing for vesting of shares over a four (4) year period, with the first twenty-five percent (25%) of such shares
vesting following twelve (12) months of continued employment or service, and the remaining shares vesting in equal monthly installments
over the following thirty-six (36) months. In addition, unless otherwise approved by the Board of Directors, including at least
two of the Preferred Directors, the Company or its assignee shall retain a “right of first refusal” on employee transfers
until the Company’s QPO and shall have the right to repurchase unvested shares at cost upon termination of employment of
a holder of restricted stock and stock issued as a result of early exercised options.

 

Section 7.22                       
Vote to Increase Authorized Common Stock. Each Stockholder agrees to vote or cause to be voted all Shares
owned by such Stockholder, or over which such Stockholder has voting control, from time to time and at all times, in whatever manner
as shall be necessary to increase the number of authorized shares of Common Stock from time to time to ensure that there will be
sufficient shares of Common Stock available for conversion of all of the shares of Preferred Stock outstanding at any given time.

 

Section 7.23                       
Term. Except as provided below, the covenants set forth in this Article VII shall terminate upon the
closing of a QPO. Notwithstanding the foregoing, the covenants set forth in Section 7.6 hereof shall continue for so long

forth in Sections 7.19 and 7.20 shall continue for so long as any Investor holds any Shares or until the expiration
of the applicable statute of limitations, if later.

 

Section 7.24                       
Tax Reporting. The Company will use commercially reasonable efforts to comply with any obligation imposed
on the Company to make any required U.S. Federal Income Tax filing (including any filing on the Internal Revenue Service Form 5471)
as a result of any interest that the Company holds in a non-U.S. Person or any activities that the Company conducts outside of
the U.S. and shall use commercially reasonable efforts to include in such filing any information necessary to obviate (to the extent
reasonably practicable) any similar obligation to which any shareholder would otherwise be subject with respect to such interest
or such activity. The Company shall promptly provide each Investor with a copy of any such filing upon request.

 

Section 7.25                       
Export Compliance. The Company shall: (a) prepare and file all required filings with the U.S. Commerce Department
and/or the U.S. Department of State necessary in order to be, or become, compliant with United States export regulations and (b)
prepare and file all required filings with the appropriate governmental entity to be, or become, compliant with the export regulations

Remedies; Severability. It is specifically understood and agreed that any breach of the provisions of this
Agreement by any Person subject hereto will result in irreparable injury to the other parties hereto, that the remedy at law alone

such other parties may enforce their respective rights by actions for specific performance (to the extent permitted by law) and

Law Governing. This Agreement shall be construed and enforced in accordance with and governed by the laws

shall specifically agree to be bound by the terms hereof as a condition of such successor. The rights of the Investors hereunder

except as provided herein without the prior written consent of the Company and a Majority Interest, and without such prior written
consent any attempted Transfer shall be null and void.

EACH PARTY ACKNOWLEDGES
AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES AND,

FOURTH AMENDED AND
RESTATED REGISTRATION RIGHTS AGREEMENT

 

This FOURTH AMENDED AND RESTATED
REGISTRATION RIGHTS AGREEMENT (the “Agreement”) is dated as of April 12, 2019, by and among 908 Devices Inc., a Delaware
corporation (the “Company”), and the persons identified on the signature pages hereto (collectively, the “Investors,”
and each individually, an “Investor”).

 

WHEREAS, the parties to
this Agreement are simultaneously entering into a certain Series E Stock Purchase Agreement, dated as of the date hereof (the “Purchase
Agreement”), whereby the Investors have agreed to purchase shares of Series E Preferred Stock (the “Securities”)
from the Company for an aggregate purchase price of up to $17,500,000; and

 

WHEREAS, the Company and
certain Investors have previously entered into that certain Third Amended and Restated Registration Rights Agreement dated as of
March 2, 2017 (the “Prior Agreement”);

 

WHEREAS, the execution
of this Agreement is an inducement and a condition precedent to the purchase by the Investors of the Securities under the Purchase
Agreement;

 

WHEREAS, to induce certain
Investors to enter into the Purchase Agreement and purchase shares of Series E Preferred Stock thereunder, the Company and the
Investors have agreed to amend and restate the Prior Agreement and to accept the rights created pursuant hereto in lieu of the
rights created under the Prior Agreement.

 

NOW, THEREFORE, in consideration
of the premises, as an inducement to the Investors to consummate the transactions contemplated by the Purchase Agreement, and for
other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the Company and the Investors
hereby covenant and agree with each other as follows:

 

1.            Certain
Definitions. As used in this Agreement, the following terms shall have the following respective meanings:

 

“Commission”
shall mean the United States Securities and Exchange Commission, or any other federal agency administering the Securities Act and
the Exchange Act at the time.

 

“Common Stock”
shall mean the Common Stock and any other common equity securities issued by the Company, and any other shares of stock issued
or issuable with respect thereto (whether by way of a stock dividend or stock split or in exchange for or upon conversion of such
shares or otherwise in connection with a combination of shares, recapitalization, merger, consolidation or other corporate reorganization).

 

“Exchange
Act” shall mean the Securities Exchange Act of 1934, as amended, or any similar successor federal statute, and the rules
and regulations of the Commission thereunder, all as the same shall be in effect at the time.

 

“Person”
shall mean an individual, a corporation, a partnership, a joint venture, a trust, an unincorporated organization, a limited liability
company or partnership, a government and any agency or political subdivision thereof.

 

“Registrable
Securities” shall mean (i) any shares of Common Stock held by the Investors at any time, and (ii) any other securities
issued and issuable to the Investors with respect to any such shares described in clause (i) above by way of a stock dividend
or stock split or in connection with a combination of shares, recapitalization, merger, consolidation or other reorganization
(it being understood that for purposes of this Agreement, a Person will be deemed to be a holder of Registrable Securities whenever
such Person has the right to then acquire or obtain from the Company any Registrable Securities, whether or not such acquisition
has actually been effected).

 

    1

    

    

 

“Registration Expenses” shall mean
the expenses so described in Section 6 hereof.

 

“Securities Act”
shall mean the Securities Act of 1933, as amended, or any similar successor federal statute, and the rules and regulations of the
Commission thereunder, all as the same shall be in effect at the time.

 

All other capitalized
terms not defined herein shall have the meaning set forth in the Purchase Agreement unless otherwise indicated.

 

 2.            Demand Registration.

 

(a)             At any time after one hundred eighty (180) days after the initial public offering of the Company’s Common Stock
pursuant to an effective registration under the Securities Act, the holders of a majority of the Registrable Securities may notify
the Company that they intend to offer or cause to be offered for public sale all or any portion of their Registrable Securities
in the manner specified in such request. Upon receipt of such request, the Company shall promptly deliver notice of such request
to all Investors holding Registrable Securities who shall then have thirty (30) days to notify the Company in writing of their
desire to be included in such registration. If the request for registration contemplates an underwritten public offering, the Company
shall state such in the written notice and in such event the right of any Person to participate in such registration shall be conditioned
upon such Person’s participation in such underwritten public offering and the inclusion of such Person’s Registrable
Securities in the underwritten public offering to the extent provided herein. The Company will use its best efforts to expeditiously
effect (but in any event no later than sixty (60) days after such request) the registration of all Registrable Securities whose
holders request participation in such registration under the Securities Act, but only to the extent provided for in this Agreement;
provided, however, that the Company shall not be required to effect registration pursuant to a request under this Section 2 more
than two (2) times for the holders of the Registrable Securities as a group. Notwithstanding anything to the contrary contained
herein, no request may be made under this Section 2 within ninety (90) days after the effective date of a registration statement
filed by the Company covering a firm commitment underwritten public offering in which the holders of Registrable Securities shall
have been entitled to join pursuant to Section 4 and in which there shall have been effectively registered all Registrable Securities
as to which registration shall have been requested. A registration will not count as a requested registration under this Section
2(a) unless and until the registration statement relating to such registration has been declared effective by the Commission at
the request of the initiating shareholders; provided, however, that a majority in interest of the participating holders of Registrable
Securities may request, in writing, that the Company withdraw a registration statement which has been filed under this Section
2(a) but has not yet been declared effective, and a majority in interest of such holders may thereafter request the Company to
reinstate such registration statement, if permitted under the Securities Act, or to file another registration statement, in accordance
with the procedures set forth herein and without reduction in the number of demand registrations permitted under this Section 2(a).

 

(b)             If a requested registration involves an underwritten public offering and the managing underwriter of such offering
determines in good faith that the number of securities sought to be offered should be limited due to market conditions, then the
number of securities to be included in such underwritten public offering shall be reduced to a number deemed satisfactory by such
managing underwriter; provided, that the shares to be excluded shall be determined in the following order of priority: (i) persons
not having any contractual or other right to include such securities in the registration statement, (ii) securities held by any
other Persons (other than the holders of Registrable Securities) having a contractual, incidental “piggy back” right
to include such securities in the registration statement, (iii) securities to be registered by the Company pursuant to such registration
statement and, if necessary, (iv) Registrable Securities. If there is a reduction of the number of Registrable Securities pursuant
to clause (iv), such reduction shall be made on a pro rata basis (based upon the aggregate number of Registrable Securities held
by such holders).

 

    2

    

    

 

(c)             With respect to a request for registration pursuant to Section 2(a) which is for an underwritten public offering,
the managing underwriter shall be chosen by the holders of a majority of the Registrable Securities to be sold in such offering
(which approval will not be unreasonably withheld or delayed). The Company may not cause any other registration of securities for
sale for its own account (other than a registration effected solely to implement an employee benefit plan or a transaction to which
Rule 145 of the Securities Act is applicable) to become effective within one hundred twenty

(120) days following the effective date of any registration
required pursuant to this Section 2.

 

3.             Form
S-3. After the first public offering of its securities registered under the Securities Act, the Company shall use its reasonable
best efforts to qualify and remain qualified to register securities pursuant to a registration statement on Form S-3 (or any successor
form) under the Securities Act. An Investor or Investors holding Registrable Securities anticipated to have an aggregate sale
price (net underwriting discounts and commissions, if any) in excess of $500,000 shall have the right to request any number of
registrations on Form S-3 (or any successor form) for the Registrable Securities held by such requesting holders. Such requests
shall be in writing and shall state the number of shares of Registrable Securities to be disposed of and the intended method of
disposition of such shares by such holder or holders. The Company shall give notice to all other holders of the Registrable Securities
of the receipt of a request for registration pursuant to this Section 3 and such holders of Registrable Securities shall then
have thirty (30) days to notify the Company in writing of their desire to participate in the registration. The Company shall use
its reasonable best efforts to effect promptly the registration of all shares on Form S-3 (or a comparable successor form) to
the extent requested by such holders. The Company shall use its reasonable best efforts to keep such registration statement effective
until the earlier of 90 days or until such holders have completed the distribution described in such registration statement.

 

4.            Piggyback
Registration. If the Company at any time proposes to register any of its securities under the Securities Act for sale to the public
(except with respect to registration statements on Forms S-4, S-8 or another form not available for registering the Registrable
Securities for sale to the public), each such time it will give written notice at the applicable address of record to each holder
of Registrable Securities of its intention to do so. Upon the written request of any of such holders of the Registrable Securities,
given within twenty (20) days after receipt by such Person of such notice, the Company will, subject to the limits contained in
this Section 4, use its reasonable best efforts to cause all such Registrable Securities of said requesting holders to be registered
under the Securities Act and qualified for sale under any state blue sky law, all to the extent required to permit such sale or
other disposition of said Registrable Securities; provided, however, that if the Company is advised in writing in good faith by
any managing underwriter of the Company’s securities being offered in a public offering pursuant to such registration statement
that the amount to be sold by persons other than the Company (collectively, “Selling Stockholders”) is greater than
the amount which can be offered without adversely affecting the offering, the Company may reduce the amount offered for the accounts
of Selling Stockholders (including such holders of shares of Registrable Securities) to a number deemed satisfactory by such managing
underwriter; and provided further, that (a) in no event shall the amount of Registrable Securities of selling Investors be reduced
below fifty percent (50%) of the total amount of securities included in such offering, unless such offering is the initial public
offering of the Company’s securities; and (b) any shares to be excluded shall be determined in the following order of priority:
(i) securities held by any Persons not having any such contractual, incidental registration rights, (ii) securities held by any
Persons having contractual, incidental registration rights pursuant to an agreement which is not this Agreement, and (iii) the
Registrable Securities sought to be included by the holders thereof as determined on a pro rata basis (based upon the aggregate
number of Registrable Securities held by such holders).

5.            Registration Procedures. If and whenever the Company is required by the provisions of this Agreement to use its best
efforts to promptly effect the registration of any of its securities under the Securities Act, the Company will:

 

(a)              use its best efforts diligently to prepare and file with the Commission a registration statement on the appropriate
form under the Securities Act with respect to such securities, which form shall comply as to form in all material respects with
the requirements of the applicable form and include all financial statements required by the Commission to be filed therewith,
and use its best efforts to cause such registration statement to become and remain effective until completion of the proposed offering;

 

(b)             use
its best efforts to diligently prepare and file with the Commission such amendments and supplements to such registration statement
and the prospectus used in connection therewith as may be necessary to keep such registration statement effective until the Holder
or Holders have completed the distribution described in such registration statement and to comply with the provisions of the Securities
Act with respect to the sale or other disposition of all securities covered by such registration statement whenever the seller
or sellers of such securities shall desire to sell or otherwise dispose of the same, but only to the extent provided in this Agreement;

 

(c)              furnish
to each selling holder and the underwriters, if any, such number of copies of such registration statement, any amendments thereto,
any documents incorporated by reference therein, the prospectus, including a preliminary prospectus, in conformity with the requirements
of the Securities Act, and such other documents as such selling holder may reasonably request in order to facilitate the public
sale or other disposition of the securities owned by such selling holder;

 

(d)             use
its best efforts to register or qualify the securities covered by such registration statement under such other securities or state
blue sky laws of such jurisdictions as each selling holder shall request, and do any and all other acts and things which may be
necessary under such securities or blue sky laws to enable such selling holder to consummate the public sale or other disposition
in such jurisdictions of the securities owned by such selling holder, except that the Company shall not for any such purpose be
required to qualify to do business as a foreign corporation in any jurisdiction wherein it is not so qualified;

 

(e)             within
a reasonable time before each filing of the registration statement or prospectus or amendments or supplements thereto with the
Commission, furnish to counsel selected by the holders of Registrable Securities copies of such documents proposed to be filed,
which documents shall be subject to the approval of such counsel;

 

(f)              immediately
notify each selling holder of Registrable Securities, such selling holder’s counsel and any underwriter and (if requested
by any such Person) confirm such notice in writing, of the happening of any event which makes any statement made in the registration
statement or related prospectus untrue or which requires the making of any changes in such registration statement or prospectus
so that they 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 the light of the circumstances under which they were made not misleading;
and, as promptly as practicable thereafter, prepare and file with the Commission and furnish a supplement or amendment to such
prospectus so that, as thereafter deliverable to the purchasers of such Registrable Securities, such prospectus will not contain
any untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in the light
of the circumstances under which they were made, not misleading;

 

    4

    

    

 

(g)             use
its best efforts to prevent the issuance of any order suspending the effectiveness of a registration statement, and if one is
issued use its best efforts to obtain the withdrawal of any order suspending the effectiveness of a registration statement at
the earliest possible moment;

 

(h)             if
requested by the managing underwriter or underwriters (if any), any selling holder, or such selling holder’s counsel, promptly
incorporate in a prospectus supplement or post effective amendment such information as such Person requests to be included therein,
including, without limitation, with respect to the securities being sold by such selling holder to such underwriter or underwriters,
the purchase price being paid therefor by such underwriter or underwriters and with respect to any other terms of an underwritten
offering of the securities to be sold in such offering, and promptly make all required filings of such prospectus supplement or
post effective amendment;

 

(i)               make
available to each selling holder, any underwriter participating in any disposition pursuant to a registration statement, and any
attorney, accountant or other agent or representative retained by any such selling holder or underwriter (collectively, the “Inspectors”),
all financial and other records, pertinent corporate documents and properties of the Company (collectively, the “Records”),
as shall be reasonably necessary to enable them to exercise their due diligence responsibility, and cause the Company’s
officers, directors and employees to supply all information requested by any such Inspector in connection with such registration
statement;

 

(j)              enter into any reasonable underwriting agreement required by the proposed underwriter(s) for the selling holders,
if any, and use its best efforts to facilitate the public offering of the securities;

 

(k)             furnish
to each prospective selling holder a signed counterpart, addressed to the prospective selling holder, of (A) an opinion of counsel
for the Company, dated the effective date of the registration statement, and (B) a “comfort” letter signed by the
independent public accountants who have certified the Company’s financial statements included in the registration statement,
covering substantially the same matters with respect to the registration statement (and the prospectus included therein) and (in
the case of the accountants’ letter) with respect to events subsequent to the date of the financial statements, as are customarily
covered (at the time of such registration) in opinions of the Company’s counsel and in accountants’ letters delivered
to the underwriters in underwritten public offerings of securities;

 

(l)              cause
the securities covered by such registration statement to be listed on the securities exchange or quoted on the quotation system
on which the Common Stock of the Company is then listed or quoted (or if the Common Stock is not yet listed or quoted, then on
such exchange or quotation system as the selling holders of Registrable Securities and the Company shall determine);

 

(m)            otherwise
use its best efforts to comply with all applicable rules and regulations of the Commission and make generally available to its
security holders, in each case as soon as practicable, but not later than 30 days after the close of the period covered thereby,
an earnings statement of the Company which will satisfy the provisions of Section 11(a) of the Securities Act and Rule 158 thereunder
(or any comparable successor provisions);

 

    5

    

    

 

(n)             otherwise
cooperate with the underwriter(s), the Commission and other regulatory agencies and take all actions and execute and deliver or
cause to be executed and delivered all documents necessary to effect the registration of any securities under this Agreement;
and

 

(o)             during
the period when the prospectus is required to be delivered under the Securities Act, promptly file all documents required to be
filed with the Commission pursuant to Sections 13(a), 13(c), 14, or 15(d) of the Exchange Act.

 

6.            Expenses. All expenses incurred by the Company or the Investors in effecting the registrations provided for in Sections
2 and 4, including, without limitation, all registration and filing fees, printing expenses, fees and disbursements of counsel
for the Company, and one counsel (which such counsel’s fees and disbursements shall be in an amount not to exceed $75,000
per registration) for the Investors participating in such registration as a group (selected by the holders of a majority of the
Registrable Securities who participate in the registration), underwriting expenses (other than fees, commissions or discounts),
expenses of any audits incident to or required by any such registration and expenses of complying with the securities or blue sky
laws of any jurisdictions (all of such expenses referred to as “Registration Expenses”), shall be paid by the Company.
All expenses incurred by the Investors in effecting the registrations provided for in Section 3 shall be paid by the Investors.

 

 7.            Indemnification.

 

(a)              The
Company shall indemnify and hold harmless each Investor that is a selling holder of Registrable Securities (including its partners
(including partners of partners and shareholders of such partners)), each underwriter (as defined in the Securities Act), and
directors, officers, employees and agents of any of them, and each other Person who participates in the offering of such securities
and each other Person, if any, who controls (within the meaning of the Securities Act) such seller, underwriter or participating
Person (individually and collectively, the “Indemnified Person”) against any losses, claims, damages or liabilities
(collectively, the “liability”), joint or several, to which such Indemnified Person may become subject under the Securities
Act or any other statute or at common law, insofar as such liability (or action in respect thereof) arises out of or is based
upon (i) any untrue statement or alleged untrue statement of any material fact contained, on the effective date thereof, in any
registration statement under which such securities were registered under the Securities Act, any preliminary prospectus or final
prospectus contained therein, or any amendment or supplement thereto, or (ii) any omission or alleged omission to state therein
a material fact required to be stated therein or necessary to make the statements therein not misleading, or (iii) any violation
by the Company of the Securities Act, any state securities or “blue sky” laws or any sale or regulation thereunder
in connection with such registration. Except as otherwise provided in Section 7(d), the Company shall reimburse each such Indemnified
Person in connection with investigating or defending any such liability; provided, however, that the Company shall not be liable
to any Indemnified Person in any such case to the extent that any such liability arises out of or is based upon any untrue statement
or alleged untrue statement or omission or alleged omission made in such registration statement, preliminary or final prospectus,
or amendment or supplement thereto in reliance upon and in conformity with information furnished in writing to the Company by
such Person specifically for use therein; and provided further, that the Company shall not be required to indemnify any Person
against any liability arising from any untrue or misleading statement or omission contained in any preliminary prospectus if such
deficiency is corrected in the final prospectus or for any liability which arises out of the failure of any Person to deliver
a prospectus as required by the Securities Act regardless of any investigation made by or on behalf of such Indemnified Person
and shall survive transfer of such securities by such seller.

 

    6

    

    

 

(b)             Each
Investor holding of any securities included in such registration being effected shall indemnify and hold harmless each other selling
holder of any securities, the Company, its directors and officers, each underwriter and each other Person, if any, who controls
(within the meaning of the Securities Act) the Company or such underwriter (individually and collectively also the “Indemnified
Person”), against any liability, joint or several, to which any such Indemnified Person may become subject under the Securities
Act or any other statute or at common law, insofar as such liability (or actions in respect thereof) arises out of or is based
upon (i) any untrue statement or alleged untrue statement of any material fact contained, on the effective date thereof, in any
registration statement under which securities were registered under the Securities Act at the request of such selling Investor,
any preliminary prospectus or final prospectus contained therein, or any amendment or supplement thereto, or (ii) any omission
or alleged omission by such selling Investor to state therein a material fact required to be stated therein or necessary to make
the statements therein not misleading, in the case of (i) and (ii) to the extent, but only to the extent, that such untrue statement
or alleged untrue statement or omission or alleged omission was made in such registration statement, preliminary or final prospectus,
amendment or supplement thereto in reliance upon and in conformity with information furnished in writing to the Company by such
selling Investor specifically for use therein regarding itself or the Registrable Securities held by it. Such selling Investor
shall reimburse any Indemnified Person for any legal fees incurred in investigating or defending any such liability; provided,
however, that in no event shall the liability of any Investor for indemnification under this Section 7 in its capacity as a seller
of Registrable Securities exceed the lesser of (i) that proportion of the total of such losses, claims, damages, expenses or liabilities
indemnified against equal to the proportion of the total securities sold under such registration statement which is being held
by such Investor, or (ii) the amount equal to the net proceeds to such Investor of the securities sold in any such registration;
and provided further, however, that no selling Investor shall be required to indemnify any Person against any liability arising
from any untrue or misleading statement or omission contained in any preliminary prospectus if such deficiency is corrected in
the final prospectus or for any liability which arises out of the failure of any Person to deliver a prospectus as required by
the Securities Act.

 

(c)             Indemnification
similar to that specified in Sections 7(a) and (b) shall be given by the Company and each selling holder (with such modifications
as may be appropriate) with respect to any required registration or other qualification of their securities under any federal
or state law or regulation of governmental authority other than the Securities Act.

 

(d)             In
the event the Company, any selling holder or other Person receives a complaint, claim or other notice of any liability or action,
giving rise to a claim for indemnification under Sections 7(a), (b) or (c) above, the Person claiming indemnification under such
paragraphs shall promptly notify the Person against whom indemnification is sought of such complaint, notice, claim or action,
and such indemnifying Person shall have the right to investigate and defend any such loss, claim, damage, liability or action.

 

(e)              If
the indemnification provided for in this Section 7 for any reason is held by a court of competent jurisdiction to be unavailable
to an Indemnified Person in respect of any losses, claims, damages expenses or liabilities referred to therein, then each indemnifying
party under this Section 7, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or
payable by such indemnified party as a result of such losses, claims, damages, expenses or liabilities (i) in such proportion
as is appropriate to reflect the relative benefits received by the Company, the Investor, or Investors and the underwriters from
the offering of Registrable Securities or (ii) if the allocation provided by clause (i) above is not permitted by applicable law,
in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative
fault of the Company, the other Investors and the underwriters in connection with the statements or omissions which resulted in
such losses, claims, damages expenses or liabilities, as well as any other relevant equitable considerations. The relative benefits
received by the Company, the Investors and the underwriters shall be deemed to be in the same respective proportions that the
net proceeds from the offering (before deducting expenses) received by the Company, the Investors, and the underwriting discount
received by the underwriters, in each case as set forth in the table on the cover page of the applicable prospectus, bear to the
aggregate public offering price of the Registrable Securities. The relative fault of the Company, the Investors and the underwriters
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 Company, the Investors, or the
underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such
statement or omission.

 

    7

    

    

 

The Company, the Investors
and the Underwriters agree that it would not be just and equitable if contribution to this Section 7 were determined by pro rata
or per capita allocation or by any other method of allocation which does not take account the equitable considerations referred
to in the immediately preceding paragraph. In no event, however, shall an Investor be required to contribute under this Section
7(e) in excess of the lesser of (i) that proportion of the total of such losses, claims, damages expenses or liabilities indemnified
against equal to the proportion of the total Registrable Securities sold under such registration statement which are being sold
by such Investor or (ii) the net proceeds received by such Investor from its sale of Registrable Securities under such registration
statement. No Person found guilty of fraudulent representation (within the meaning of Section 11(f) of the Securities Act) shall
be entitled to contribution from any person who was not found guilty of such fraudulent misrepresentation.

 

(f)              The
amount paid by an indemnifying party or payable to an Indemnified Person as a result of the losses, claims, damages, expenses
and liabilities referred to in this Section 7 shall be deemed to include, subject to limitations set forth above, any legal or
other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or
claim, payable as the same are incurred. The indemnification and contribution provided for in this Section 7 will remain in full
force and effect regardless of any investigation made by or on behalf of the indemnified parties or any other officer, director,
employee, agent or controlling person of the indemnified parties. No indemnifying party, in the defense of any such claim or litigation,
shall enter into a consent or entry of any judgment or enter into a settlement without the consent of the Indemnified Person,
which consent will not be unreasonably withheld or delayed.

 

8.            Compliance
with Rule 144. In the event that the Company (i) registers a class of securities under Section 12 of the Exchange Act or (ii)
shall commence to file reports under Section 13 or 15(d) of the Exchange Act, the Company will use its best efforts thereafter
to file with the Commission such information as is required under the Exchange Act for so long as there are holders of Registrable
Securities; and in such event, the Company shall use its best efforts to take all action as may be required as a condition to
the availability of Rule 144 under the Securities Act (or any comparable successor rules). The Company shall furnish to any holder
of Registrable Securities upon request a written statement executed by the Company as to the steps it has taken to comply with
the current public information requirement of Rule 144 (or such comparable successor rules). After the occurrence of the first
underwritten public offering of Common Stock of the Company pursuant to an offering registered under the Securities Act on Form
S-1 (or any comparable successor forms), subject to the limitations on transfers imposed by this Agreement, the Company shall
use its best efforts to facilitate and expedite transfers of Registrable Securities pursuant to Rule 144 under the Securities
Act, which efforts shall include timely notice to its transfer agent to expedite such transfers of Registrable Securities.

 

9.             Rule
144A Information. The Company shall, upon written request of any Investor, provide to such Investor and to any prospective institutional
transferee of the Common Stock designated by such Investor, such financial and other information as is available to the Company
or can be obtained by the Company without material expense and as such Investor may reasonably determine is required to permit
such transfer to comply with the requirements of Rule 144A promulgated under the Securities Act.

 

    8

    

    

 

10.          Amendments.
The provisions of this Agreement may be amended, and the Company may take any action herein prohibited or omit to perform any
act herein required to be performed by it, only if the Company has obtained the written consent of the holders of a majority of
the Registrable Securities. For the purposes of this Agreement and all agreements executed pursuant hereto, no course of dealing
between or among any of the parties hereto and no delay on the part of any party hereto in exercising any rights hereunder or
thereunder shall operate as a waiver of the rights hereof and thereof.

 

11.          Postponement.
The Company may postpone the filing of any registration statement required hereunder for a reasonable period of time, not to exceed
ninety (90) days in the aggregate during any twelve month period, if the Company has been advised by legal counsel that such filing
would require a special audit or the disclosure of a material impending transaction or other matter and the Company’s Board
of Directors determines reasonably and in good faith that such disclosure would have a material adverse effect on the Company
(a “Black Out Period”). Upon notice of the existence of a Black Out Period from the Company to any Investor or Investors
with respect to any registration statement already effective, such Investor or Investors shall refrain from selling their Registrable
Securities under such registration statement until such Black Out Period has ended; provided, however, that the Company shall
not impose a Black Out Period with respect to any registration statement that is already effective more than once during any period
of twelve (12) consecutive months and in no event shall such Black Out Period exceed sixty (60) days.

 

12.           Market
Stand Off. Each Investor 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 one hundred eighty (180) days in
the case of the IPO, or 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 (whether
such shares or any such securities are then owned by the Investor or are thereafter acquired) 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 12 shall not apply to the sale of any shares to an underwriter
pursuant to an underwriting agreement, and shall be applicable to the Investors 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 Common Stock (after giving effect to conversion
into Common Stock of all outstanding Preferred Stock). Any discretionary waiver or termination of the restrictions of any or all
of such agreements by the Company or the underwriters shall apply pro rata to all stockholders that are subject to such agreements,
based on the number of shares subject to such agreements. The underwriters in connection with such registration are intended third
party beneficiaries of this Section 12 and shall have the right, power, and authority to enforce the provisions hereof as though
they were a party hereto. Each Investor 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 12 or that are necessary to give further effect thereto.

 

    9

    

    

 

13.          Transferability
of Registration Rights. The registration rights set forth in this Agreement are transferable to each transferee of Registrable
Securities. Each subsequent holder of Registrable Securities must consent in writing to be bound by the terms and conditions of
this Agreement in order to acquire the rights granted pursuant to this Agreement.

 

14.          Rights
Which May Be Granted to Subsequent Investors. Other than permitted transferees of Registrable Securities under this Section, the
Company shall not, without the prior written consent of holders of a majority of the Series A Preferred Stock, Series B Preferred
Stock, Series C Preferred Stock, Series D Preferred Stock and Series E Preferred Stock, voting together as a single class, (a)
allow purchasers of the Company’s securities to become a party to this Agreement or (b) grant any other registration rights
other than any incidental or so called piggyback registration rights to any third parties that are not inconsistent with the terms
of this Agreement.

 

15.          Damages.
The Company recognizes and agrees that each holder of Registrable Securities will not have an adequate remedy if the Company fails
to comply with the terms and provisions of this Agreement and that damages will not be readily ascertainable, and the Company
expressly agrees that, in the event of such failure, it shall not oppose an application by any holder of Registrable Securities
or any other Person entitled to the benefits of this Agreement requiring specific performance of any and all provisions hereof
or enjoining the Company from continuing to commit any such breach of this Agreement.

 

 16.          Miscellaneous.
