Act on Form S-3 (or any successor short form registration statement), a Holder or Holders of the Senior Required Securities shall have the right to make written requests that the Issuer effect a registration under the Securities Act on Form S-3 of

pursuant to Section 2.1(a) or 2.1(b), the Issuer shall promptly give written notice of such requested registration to all Holders, and thereupon will use its best efforts to effect the registration under the Securities Act of:

(in accordance with the intended methods thereof as aforesaid) of the Registrable Securities so to be registered. 
 (d)
Effective Registration Statement. A registration requested pursuant to Section 2.1(a) or 2.1(b) shall not be deemed to have been effected unless the Registration Statement for such registration is declared effective by the SEC and
remains effective for the period specified in Section 2.3(b). Notwithstanding the preceding sentence, a registration requested pursuant to Section 2.1(a) or 2.1(b) that does not become effective after the Issuer has filed a Registration
Statement with respect thereto by reason of the refusal to proceed of the Holders of Registrable Securities requesting the registration, or by reason of a request by the Holders of (x) at least seventy-five percent (75%) of the combined
voting power of the issued and outstanding Senior Preferred Stock (voting as a single class in accordance with Article FOURTH, Part C, Subsection 3.1 of the Certificate of Incorporation) in the case of a registration requested pursuant to
Section 2.1(a)(i) or (y) the Senior Required Securities in the case of a registration requested pursuant to Section 2.1(a)(ii) for which registration is being requested that such registration be withdrawn, shall be deemed to have been
effected by the Issuer at the request of such Holders.

seventy-five percent (75%) of the combined voting power of the issued and outstanding Senior Preferred Stock (voting as a single class in accordance with Article FOURTH, Part C, Subsection 3.1 of the Certificate of Incorporation) in the case of
a registration requested pursuant to Section 2.1(a)(i) or (y) the Senior Required Securities in the case of a registration requested pursuant to Section 2.1(a)(ii) or 2.1(b) determine, based on consultation with the managing
underwriters or, in an offering that is not underwritten, with an investment banker, that the number of securities to be sold in any such offering should be limited due to market conditions or otherwise, Holders of Registrable Securities proposing
to sell their securities in such registration shall be entitled to include in such registration: 
 (i) first, all Senior
Registrable Securities requested to be included by the Holders, allocated pro rata based on the number of Senior Registrable Securities as to which registration was requested by such Holders; 

(ii) second, to the extent that the number of shares registered pursuant to clause (i) above is less than the number of
securities to be sold in such offering, the remaining Registrable Securities requested to be included by the Holders, pro rata based on the number of such Registrable Securities as to which registration was requested by such Holders. 

  
 - 7 - 








 (f) Inclusion of Other Securities in Demand Registration. 

(i) The Issuer may, subject to the remainder of this Section 2.l(f), elect to include in any Registration Statement made
pursuant to Section 2.1(a) or 2.1(b), authorized but unissued shares of Common Stock, or shares of Common Stock held as treasury stock, provided, however that in the event that (i) such Registration Statement was made
pursuant to Section 2.1(a), (ii) the Issuer elects to include such shares of Common Stock in such Registration Statement and (iii) the number of shares requested pursuant to Section 2.1(a) is reduced pursuant to
Section 2.1(f)(ii), then the registration made with regard to such Registration Statement will not be deemed to be one of the two allowable registration requests permitted to be made pursuant to Section 2.1(a). 

(ii) If any Registration Statement made pursuant to Section 2.1(a) or 2.1(b) involves an underwritten offering and the
managing underwriter of such offering (or, in connection with an offering that is not underwritten, an investment banker) shall advise the Issuer that the number of securities requested to be included in such registration exceeds the largest number
that can be sold in an orderly manner in such offering within a price range acceptable to the selling Holders, the Issuer shall include in such registration: 

(A) first, all shares of Common Stock requested to be included in such registration by the selling Holders subject to
Section 2.1(e); 
 (B) second, to the extent that the number of securities to be registered pursuant to clause
(A) above is less than the largest number that can be sold in an orderly manner in such offering within a price range acceptable to the selling Holders, securities that the Issuer proposes to register; and 

(C) third, to the extent that the number of shares registered pursuant to clauses (A) and (B) above is less than the
largest number that can be sold in an orderly manner in such offering within a price range acceptable to the selling Holders, the securities requested to be included by any other holders. 

The securities to be included in any such registration pursuant to clause (C) shall be allocated on a pro rata basis among all holders
requesting that securities be included in such registration pursuant to such clause on the basis of the number of securities requested to be included by such holders. 

2.2 Piggyback Registration. If the Issuer at any time proposes to register any Common Stock under the Securities Act
(other than pursuant to a Registration Statement relating solely to the sale of securities on Form S-4 with respect to any merger, consolidation or acquisition, pursuant to Section 2.1 or pursuant to a Special Registration), whether or not for
sale for its own account, and the registration form to be used may be used for the registration of Registrable Securities, it shall give prompt written notice to all Holders of its intention to do so and, upon the written request of any Holder given
to the Issuer within 10 days after the Issuer has given any such notice (which request shall specify the Registrable Securities intended to be disposed of by such Holder and the intended method of disposition thereof), the Issuer will use its best
efforts to effect the registration under the Securities Act of all Registrable Securities that the Issuer has been so requested to register by the Holders thereof, to the extent required to permit the disposition (in accordance with the intended
methods thereof as aforesaid) of the Registrable Securities so to be registered, provided that: 

  
 - 8 - 








 (a) if, at any time after giving written notice of its intention to register any
Common Stock and prior to the effective date of the Registration Statement filed in connection with such registration, the Issuer shall determine for any reason not to register such Common Stock, the Issuer may, at its election, give written notice
of such determination to each Holder that was previously notified of such registration and, thereupon, shall not register any Registrable Securities in connection with such registration (but shall nevertheless pay the Registration Expenses in
connection therewith), without prejudice, however, to the rights of any Holders to request that a registration be effected under Section 2.1; and 

(b) if the Issuer shall be advised in writing by the managing underwriters (or, in connection with an offering that is not
underwritten, by an investment banker) that due to marketing factors, the number of securities requested to be included in such registration exceeds the number of such securities that can be sold in such offering in an orderly manner within a price
range that is acceptable to the Issuer, the Issuer shall include in such registration: 
 (i) first, all shares of Common
Stock that the Issuer proposes to register for its own account or the account of the holder or holders initially requesting or demanding such registration; 

(ii) second, to the extent that the number of shares registered pursuant to clause (i) above is less than the largest
number that can be sold in an orderly manner in such offering within a price range acceptable to the Issuer, the Registrable Securities requested to be included by the Holders subject to Section 2.1(e); 

(iii) third, to the extent that the number of shares registered pursuant to clauses (i) and (ii) above is less than
the largest number that can be sold in an orderly manner in such offering within a price range acceptable to the Issuer, the securities requested to be included by any other holders, 

and the Issuer shall so provide in any registration agreement hereinafter entered into with respect to any of its securities. 

The securities to be included in any such registration pursuant to clause (ii) or (iii) shall be allocated on a pro rata basis among all holders
requesting that securities be included in such registration pursuant to such clause on the basis of the number of securities requested to be included by such holders (in the case of clause (ii), subject to Section 2.1(e)). 

Subject to Section 2.5, no registration effected under this Section 2.2 shall relieve the Issuer from its obligation to effect
registrations upon request under Section 2.1. Nothing in this Agreement shall prevent any Holder from making a request under this Section 2.2 prior to converting the Preferred Shares. 

2.3 Registration Procedures. If and whenever the Issuer is required to use its best efforts to effect the registration
of any Registrable Securities under the Securities Act as provided in Sections 2.1 and 2.2, the Issuer shall: 
 (a) prepare
and file with the SEC, as soon as practicable, a Registration Statement with respect to such securities, make all required filings with FINRA and use its best efforts to cause such Registration Statement to become effective at the earliest possible
date; 
 (b) prepare and file with the SEC such amendments and supplements to such Registration Statement and the Prospectus
used in connection therewith and such other documents as may

be necessary to keep such Registration Statement effective until the earlier of (i) 30 days after the effective date of such Registration Statement (360 days in the case of a shelf
registration pursuant to Section 2.1 (b)) or (ii) the consummation of the disposition by the Holders of all the Registrable Securities covered by such Registration Statement, and otherwise comply with the provisions of the Securities
Act with respect to the disposition of all securities covered by such Registration Statement;

Holders of Registrable Securities, the underwriters and their respective counsels in connection with the registration or qualification (or exemption from such registration or qualification) of the securities covered by such Registration Statement

perform blue sky investigations and file registrations and qualifications required to be filed pursuant to this Section 2.3(e)); keep each such registration or qualification (or exemption therefrom) effective during the period such Registration
Statement is required to be effective hereunder and do any and all other acts and things that may be necessary or advisable to enable such seller to consummate the disposition in such jurisdictions of the securities owned by such seller;
provided, however, that the Issuer shall not be required in connection with this paragraph (e) to qualify as a foreign corporation or to execute a general consent to service of process in any jurisdiction or to amend its
Certificate of Incorporation or Bylaws in a manner that the Board of Directors of the Issuer determines is inadvisable; 

(f) (i) notify each Holder of Registrable Securities subject to such Registration Statement if such Registration Statement, at
the time it or any amendment thereto became effective, (x) contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading upon

promptly as practicable, prepare and file with the SEC a post-effective amendment to such Registration Statement and use best efforts to cause such post-effective amendment to become effective such that such Registration Statement, as so amended,
shall not contain an untrue 

  
 - 10 - 








 
statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading, and (ii) notify each Holder of
Registrable Securities subject to such Registration Statement, at any time when a Prospectus relating thereto is required to be delivered under the Securities Act, if the Prospectus included in such Registration Statement, as then in effect,
includes an untrue statement of a material fact or omits to state a 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 upon discovery by
the Issuer of such material misstatement or omission or upon discovery by the Issuer of the happening of any event as a result of which the Issuer believes there would be such a material misstatement or omission, and, as promptly as is practicable,
prepare and furnish to such Holder a reasonable number of copies of a supplement to or an amendment of such Prospectus as may be necessary so that, as thereafter delivered to the purchasers of such securities, such Prospectus shall not include an
untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading and each such Holder of
Registrable Securities shall immediately discontinue any sales of Registrable Securities pursuant to such Registration Statement until such Holder of Registrable Securities has received copies of a supplemented or amended Prospectus or until such
Holder of Registrable Securities is advised in writing by the Issuer 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; 
 (g) otherwise use its best efforts to comply with all applicable rules and regulations of the SEC, and make
available to its security holders, as soon as reasonably practicable, an earnings statement of the Issuer complying with the provisions of Section 11(a) of the Securities Act and Rule 158 promulgated under the Securities Act (or any similar
rule promulgated under the Securities Act) no later than 45 days after the end of any 12-month period (or 90 days after the end of any 12-month period if such period is a fiscal year) (i) commencing at the end of any fiscal quarter in which
Registrable Securities are sold to an underwriter or to underwriters in a firm commitment or best efforts underwritten offering and (ii) if not sold to an underwriter or to underwriters in such an offering, commencing on the first day of the
first fiscal quarter of the Issuer after the effective date of the relevant Registration Statement, which statements shall cover said 12-month periods; 

(h) promptly notify each Holder of any Registrable Securities covered by such Registration Statement, their counsel and the
underwriters (i) when such Registration Statement, or any post-effective amendment to such Registration Statement, shall have become effective, or any amendment of or supplement to the Prospectus used in connection therewith shall have been
filed, (ii) of any request by the SEC to amend such Registration Statement or to amend or supplement such Prospectus or for additional information, (iii) of the issuance by the SEC of any stop order suspending the effectiveness of such
Registration Statement or of any order preventing or suspending the use of any preliminary prospectus or the initiation or threatening of any proceedings for any of such purposes, (iv) of the suspension of the qualification of such securities
for offering or sale in any jurisdiction, or of the institution of any proceedings for any of such purposes and (v) if at any time when a Prospectus is to be required by the Securities Act to be delivered in connection with the sale of the
Registrable Securities, the representations and warranties of the Issuer contained in any agreement (including the underwriting agreement contemplated in Section 2.4(b) below), to the knowledge of the Issuer, cease to be true and correct in any
material respect; 
 (i) use its best efforts to prevent the issuance of any order suspending the effectiveness of the
Registration Statement or of any order preventing or suspending the use of a Prospectus or suspending the qualification (or exemption from qualification) of any of the Registrable Securities covered thereby for sale in any jurisdiction, and, if any
such order is issued, to use its best efforts to obtain the withdrawal of any such order at the earliest possible moment; 

(j) prior to the effective date of the Registration Statement, (i) provide the registrar or transfer agent for the Common
Stock or such other Registrable Securities with printed 

  
 - 11 - 








 
certificates for such securities in a form eligible for deposit with DTC and (ii) provide a CUSIP number for such securities; 

(k) have the right, if the Board of Directors of the Issuer, in its good faith judgment, determines that any registration of
Registrable Securities should not be made or continued because (x) it would materially interfere with any material financing, acquisition, corporation reorganization, merger, or other transaction involving the Issuer or any of its Subsidiaries
or (y) it would require the disclosure of material nonpublic information, which disclosure would have a Material Adverse Effect (each a “Valid Business Reason”), (i) to postpone filing a Registration Statement until such
Valid Business Reason no longer exists, but in no event for more than 60 days, and (ii) to cause any Registration Statement that has already been filed to be withdrawn and its effectiveness terminated or to postpone amending or supplementing
such Registration Statement until such Valid Business Reason no longer exists, but in no event for more than 60 days (the “Postponement Period”); provided, however, that in no event shall the Issuer be permitted to
postpone or withdraw a Registration Statement under this subsection (k) or otherwise within 60 days after the expiration of the Postponement Period; 

(l) participate in marketing any Registrable Securities in connection with the registration of such securities under this
Agreement (including, but not limited to, making available reasonably necessary personnel and participating in a road show) as would be customary for public offerings of this nature; and 

(m) have the right, by furnishing to the requesting Holder or Holders a certificate signed by the Chief Executive Officer (or,
if none, the President) of the Issuer stating that, in the good faith judgment of the Board of Directors of the Issuer, circumstances exist (other than the circumstances set forth in subparagraph (k)), such that it would be detrimental to the Issuer
and its investors for a registration requested pursuant to Section 2.1 to be effected at such time, to direct that such request be delayed for a period not in excess of 180 days from the receipt of the request, such right to delay a request to
be exercised by the Issuer not more than once in any twelve-month period (and not within 60 days of any Postponement Period). 
 The Issuer
may require each Holder of any Registrable Securities as to which any registration is being effected to furnish to the Issuer such information regarding such Holder and the distribution of such securities as the Issuer may from time to time
reasonably request in writing and as shall be required by law in connection therewith. Each such Holder agrees to furnish promptly to the Issuer all information required to be disclosed in order to make the information previously furnished to the
Issuer by such Holder not materially misleading. 
 By the acquisition of Registrable Securities, each Holder shall be deemed to have agreed
that upon receipt of any notice from the Issuer pursuant to Section 2.3(f) or (k), such Holder will promptly discontinue such Holder’s disposition of Registrable Securities pursuant to the Registration Statement covering such Registrable
Securities until such Holder shall have received, in the case of clause (i) of Section 2.3(f), notice from the Issuer that such Registration Statement has been amended, as contemplated by Section 2.3(f), or in the case of clause
(ii) of Section 2.3(f), copies of the supplemented or amended Prospectus contemplated by Section 2.3(f); or, in the case of Section 2.3(k), until the time period specified has elapsed or such Holder has received notice from the
Issuer that the Postponement Period has been terminated. If so directed by the Issuer, each Holder will deliver to the Issuer (at the Issuer’s expense) all copies, other than permanent file copies, in such Holder’s possession of the
Prospectus covering such Registrable Securities at the time of receipt of such notice. In the event that the Issuer shall 

  
 - 12 - 








 
give any such notice, the period mentioned in Section 2.3(b) shall be extended by the number of days during the period from and including the date of the giving of such notice to and
including the date when the Issuer shall have sent to the Holder copies of the supplemented or amended Prospectus contemplated by Section 2.3(f). 

2.4 Underwritten Offerings. The provisions of this Section 2.4 do not establish registration rights in addition to
those set forth in Sections 2.1, 2.2 and 2.3, but instead set forth procedures applicable, in addition to those set forth in Sections 2.1 through 2.3, to any registration that is an underwritten offering. 

(a) Underwritten Offerings Exclusive. Whenever a registration requested pursuant to Section 2.1 or 2.2 is for an
underwritten offering, only securities that are to be distributed by the underwriters may be included in the registration. 

(b) Underwriting Agreement. If requested by the underwriters for any underwritten offering by Holders pursuant to a
registration requested under Section 2.1, the Issuer shall enter into an underwriting agreement with such underwriters for such offering, such agreement to be reasonably satisfactory in substance and form to the Issuer and to the underwriters
and to contain such representations and warranties by the Issuer and such other terms and provisions as are customarily contained in agreements of this type, including, but not limited to, indemnities to the effect and to the extent provided in
Section 2.8, provisions for the delivery of officers’ certificates, opinions of counsel and accountants’ “cold comfort” letters, and lock-up arrangements. The Holders of Registrable Securities to be distributed by such
underwriters shall be parties to such underwriting agreement. 
 (c) Selection of Underwriters. Whenever a registration is
for an underwritten offering, the Issuer shall have the right to select one or more underwriters to administer the offering; provided that the lead underwriter shall be an underwriter of nationally recognized standing. 

2.5 Lock-Up Agreements. If and whenever the Issuer proposes to register any of its equity securities under the
Securities Act in an initial public offering, each of the Holders, (i) if required by the managing underwriter and (ii) so long as all stockholders holding 5% or more to the total outstanding shares of Common Stock and Preferred Shares of
the Issuer on a fully-diluted basis and all officers and directors of the Issuer are also restricted in their ability to transfer securities of the Issuer by terms at least as restrictive as those contained in this Section 2.5, agrees by
acquisition of such Registrable Securities not to effect (other than pursuant to such registration) any public sale or distribution, including, but not limited to, any sale pursuant to Rule 144, of any Registrable Securities, any other equity
securities of the Issuer or any securities convertible into or exchangeable or exercisable for any equity securities of the Issuer during the time periods specified by the managing underwriter (not to exceed 180 days), to the extent timely notified
in writing by the Issuer or the managing underwriter. Each holder hereby agrees to enter into a customary agreement with the managing underwriter for the initial public offering to the effect set forth in the preceding sentence. If and whenever the
Issuer is required to use its best efforts to effect the registration of any Registrable Securities under the Securities Act pursuant to Section 2.1 or 2.2, the Issuer, if required by the managing underwriter in an underwritten offering, shall
not effect (other than pursuant to such registration or a Special Registration) any public sale or distribution of any other equity securities of the Issuer or any securities convertible into or exchangeable or exercisable for any equity securities
of the Issuer during the 10 days prior to, and for 90 days (or 180 days in the case of an initial public offering) 

  
 - 13 - 








 
after, the effective date of such registration, to the extent timely notified in writing by the managing underwriter. In addition, in such circumstances, the Issuer shall use its best efforts to
cause its directors and officers and all holders of 5% or more of its equity securities (other than the Holders) not to effect (other than pursuant to such registration) any public sale or distribution, including, but not limited to, any sale
pursuant to Rule 144, of any equity securities of the Issuer or any securities convertible into or exchangeable or exercisable for any equity securities of the Issuer during the 10 days prior to, and for 90 days (or 180 days in the case of an
initial public offering) after, the effective date of such registration, to the extent timely notified in writing by the managing underwriter. 

2.6 Preparation; Reasonable Investigation. In connection with the preparation and filing of each Registration Statement
registering Registrable Securities under the Securities Act, the Issuer shall give the Holders of such Registrable Securities so to be registered and their underwriters or placement agents, if any, and their respective counsel and accountants, the
opportunity to participate in the preparation of such Registration Statement, each Prospectus included therein or filed with the SEC, and each amendment thereof or supplement thereto, and shall, upon reasonable advance notice and during normal
business hours, give one representative of the Investors such access to all pertinent financial, corporate and other documents and properties of the Issuer and its Subsidiaries, and such opportunities to discuss the business of the Issuer with its
officers, directors, employees and the independent registered public accounting firm that has issued audit reports on its financial statements as shall be reasonably necessary, in the opinion of such Holders’ and such underwriters’ or
placement agents’ respective counsel, to conduct a reasonable investigation within the meaning of the Securities Act. 

2.7 Other Registrations. If and whenever the Issuer is required to use its best efforts to effect the registration of
any Registrable Securities under the Securities Act pursuant to Section 2.1 or 2.2, and if such registration shall not have been withdrawn or abandoned, the Issuer shall not be obligated to and shall not file any Registration Statement with
respect to any of its securities (including Registrable Securities) under the Securities Act (other than a Special Registration), whether of its own accord or at the request or demand of any holder or holders of such securities, until a period of
180 days shall have elapsed from the effective date of such previous registration, provided that the Issuer shall not be prohibited from filing a registration statement by virtue of this Section 2.7 more than once in a 360 day period.

 2.8 Indemnification. 

(a) Indemnification by the Issuer. In the event of any registration of any Registrable Securities under the Securities
Act pursuant to Section 2.1 or 2.2, the Issuer shall indemnify and hold harmless the seller of such securities, its directors, officers, and employees, each other person who participates as an underwriter, broker or dealer in the offering or
sale of such securities and each other person, if any, who controls such seller or any such participating person within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, against any and all losses,
claims, damages or liabilities, joint or several, to which such seller or any such director, officer, employee, participating person or controlling person may become subject under the Securities Act or otherwise, insofar as such losses, claims,
damages or liabilities (or actions or proceedings in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of a material fact contained in any Registration Statement under which such securities
were registered under the Securities Act, any Prospectus or preliminary prospectus included therein, or any amendment or supplement thereto, or (ii) any omission or alleged omission to state a material fact required to be stated in any such
Registration Statement, Prospectus, preliminary prospectus, amendment or supplement or necessary to make the statements therein not misleading; and the Issuer shall reimburse such seller and each such director, officer, employee, participating
person and controlling person for any legal or any other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, liability, action or proceeding as such expenses are incurred; provided that the
Issuer shall not be liable in any such case to the extent that any such loss, claim, damage, liability or expense arises out of or is based upon an untrue statement or omission made in any such Registration Statement, Prospectus, preliminary
prospectus, amendment or supplement in reliance upon and in conformity with written information furnished to the Issuer by such seller or participating person expressly for use in the preparation thereof. 

  
 - 14 - 








 (b) Indemnification by the Seller. In the event of any registration of any
Registrable Securities under the Securities Act pursuant to Section 2.1 or 2.2, each of the prospective sellers of such securities, severally and not jointly, will indemnify and hold harmless the Issuer, each director of the Issuer, each
officer of the Issuer who shall sign such Registration Statement, each other person who participates as an underwriter, broker or dealer in the offering or sale of such securities and each other person, if any, who controls the Issuer or such other
participating person within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, against any and all losses, claims, damages or liabilities, joint or several, to which the Issuer or any such director, officer,
participating person or controlling person may become subject under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions or proceedings 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 securities were registered under the Securities Act, any Prospectus or preliminary prospectus included therein, or any amendment or
supplement thereto, or any omission or alleged omission to state a material fact with respect to such seller required to be stated in any such Registration Statement, Prospectus, preliminary prospectus, amendment or supplement or necessary to make
the statements therein not misleading if such statement or omission was made in reliance upon and in conformity with written information furnished to the Issuer by such seller expressly for use in the preparation of any such Registration Statement,
Prospectus, preliminary prospectus, amendment or supplement; provided that the liability of each such seller shall be in proportion to and limited to the net amount received by such seller (after deducting any underwriting discount and expenses)
from the sale of Registrable Securities pursuant to such Registration Statement. 
 (c) Notices of Claims, etc.
Promptly after receipt by an indemnified party of notice of the commencement of any action or proceeding involving a claim referred to in the preceding paragraphs of this Section 2.8, such indemnified party shall, if a claim in respect thereof
is to be made against an indemnifying party hereunder, give prompt written notice to the latter of the commencement of such action, provided that the failure of any indemnified party to give notice as provided therein shall not relieve the
indemnifying party of its obligations under the preceding paragraphs of this Section 2.8 unless the failure to provide prompt written notice shall cause actual prejudice to the indemnifying party. In case any such action is brought against an
indemnified party and it notifies the indemnifying party of the commencement thereof, the indemnifying party shall have the right to retain counsel reasonably satisfactory to such indemnified party to defend against such proceeding and shall pay the
reasonable fees and disbursements of such counsel related to such proceeding. In any such proceeding, any indemnified party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such
indemnified party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel and the payment of such fees by the indemnifying party, or (ii) the named parties to any such
proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them or
(iii) the indemnifying party has not retained counsel to defend such proceeding, in which case (under any of such clauses (i), (ii) or (iii)) it is understood that (x) the indemnifying party shall not, in connection with any
proceeding or related proceedings in the same jurisdiction, be liable for the reasonable fees and expenses of more than one separate firm for all such indemnified parties and (y) such firm shall be designated in writing by the Holders of a
majority of the Registrable Securities included in such Registration Statement in the case of parties indemnified pursuant to Section 2.8(a) and by the Issuer in the case of parties indemnified pursuant to Section 2.8(b). No indemnifying
party, in the defense of any such claim or litigation, shall, except with the consent of such indemnified party, which consent shall not be unreasonably withheld, consent to entry of any judgment or enter into any settlement of any pending or
threatened action in respect of which any indemnified party is or could have been a party and indemnity was sought hereunder by such indemnified party unless such judgment or settlement includes as an


  
 - 15 - 








 
unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect to such claim or litigation. 

(d) Other Indemnification. Indemnification similar to that specified in the preceding paragraphs of this
Section 2.8 (with appropriate modifications) shall be given by the Issuer and each seller of Registrable Securities with respect to any required registration or other qualification of such Registrable Securities under any federal or state law
or regulation of governmental authority other than the Securities Act. 
 (e) Other Remedies. If for any reason the
foregoing indemnity is unavailable, or is insufficient to hold harmless an indemnified party, other than by reason of the exceptions provided therein, then the indemnifying party shall contribute to the amount paid or payable by the indemnified
party as a result of such losses, claims, damages, liabilities or expenses in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and of the indemnified party on the other in connection with the
statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative fault 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 Issuer or the Holders of Registrable Securities covered by the Registration Statement in question and the
parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. 
 The
Issuer and the Holders agree that it would not be just and equitable if contribution pursuant to this Section 2.8 were determined by pro rata allocation or by any other method of allocation that does not take account of the equitable
considerations referred to in the immediately preceding paragraph. The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in the immediately preceding paragraph of this
Section 2.8 shall be deemed to include, subject to the 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. 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. No party shall be liable for
contribution under this Section 2.8(e) except to the extent and under such circumstances as such party would have been liable to indemnify under this Section 2.8 if such indemnification were enforceable under applicable law. 

(f) Officers and Directors. As used in this Section 2.8, the terms “officers” and “directors”
shall include the partners of Holders that are partnerships and the members of Holders that are limited liability companies. 

2.9 Expenses. The Issuer shall pay all Registration Expenses in connection with each registration of Registrable
Securities pursuant to this Section 2. All other expenses shall be borne by the Holders participating in such registration. 

2.10 Termination. All of the Issuer’s obligations to register Registrable Securities under Sections 2.1 and 2.2
shall terminate upon the earliest of (a) five years after the closing of an initial public offering, (b) the date on which no Holder holds any Registrable Securities or (c) a Company Sale. 

3. Covenants of the Issuer. The Issuer shall comply with the covenants set forth in Sections 3.1 through 3.7:

through such period; 
 (d) furnish to each Significant Holder such other information as the Holders may reasonably request
in connection with any of the transactions entered into or proposed to be entered into by the Issuer that are not in the ordinary course of the Issuer’s business; and

Section 3.1 to Novartis or any of its Affiliates if such entity is determined by the Board of Directors of the Issuer not to be a Financial Fund. 

3.2 Directors’ Indemnification and Insurance. The Certificate of Incorporation or Bylaws of the Issuer shall at all
times provide for indemnification of the directors and limitations on the liability of the directors to the fullest extent permitted under applicable state law. The Issuer will obtain and at all times maintain on reasonable business terms

 - 17 - 








 3.3 Inspection. The Issuer shall, upon reasonable prior notice to the
Issuer and during normal business hours, permit one authorized representative of any Investor to visit and inspect any of the properties of the Issuer, including its books of account, and to discuss its affairs, finances and accounts with its

provided, further, that the Issuer shall not be required to permit any action requested under this Section 3.3 by Novartis or any of its Affiliates if such entity is determined by the Board of Directors of the Issuer not to be a

including at least three Senior Preferred Designees, (i) create any stock option plan or similar stock option, equity participation or bonus arrangement or (ii) allocate, grant or otherwise award any capital stock or any securities

shares vesting in equal monthly installments over the following thirty-six (36) months. 
 3.5 Confidentiality.
Each Investor agrees that such Investor will keep confidential and will not disclose, divulge or use for any purpose, other than to monitor its investment in the Issuer, any Confidential Information, unless such Confidential Information (a) is
known or becomes known to the public in general (other than as a result of a breach of this Section 3.5 by such Investor), (b) is or has been independently developed or conceived by the Investors without use of the Issuer’s
Confidential Information or (c) is or has been made known or disclosed to the Issuer by a third party without a breach of any obligation of confidentiality such third party may have to the Issuer; provided, however, that a Investor may disclose
Confidential Information (i) to its attorneys, accountants, consultants, and other professionals to the extent necessary to obtain their services in connection with monitoring its investment in the Issuer, (ii) to any prospective purchaser
of any Shares from such Investor as long as such prospective purchaser agrees to be bound by the provisions of this Section 3.5, (iii) to any Affiliate of such Investor, provided that such party is obligated not to disclose, divulge or use
any Confidential Information to the same extent as the Investors, or (iv) as may otherwise be required by law, provided that the Investor takes reasonable steps to minimize the extent of any such required disclosure. Notwithstanding the

Agreement as to such subject matter. This Agreement may be amended, modified, changed, discharged, waived or terminated, and the Issuer may take any action herein prohibited, or omit to perform any act herein required to be performed by it, only if
the Issuer shall have obtained the written consent to such amendment, modification, change, discharge, waiver, termination, action or omission to act, of (a) the Holders of at least a majority of the Registrable Securities, (b) the Holders
of the Senior Required

Securities and (c) the holders of at least seventy-five percent (75%) of the combined voting power of the issued and outstanding Senior Preferred Stock (voting as a single class in
accordance with Article FOURTH, Part C, Subsection 3.1 of the Certificate of Incorporation); provided that no consent shall be required under clauses (a), (b) or (c) for any amendments to this Agreement that are effected as a condition to
or as part of a Qualified Liquidation Event (as defined in the Certificate of Incorporation); provided further that the Company may amend this Agreement without the consent of the Investors solely to add investors that purchase Series E Preferred
Stock pursuant to Section 2.4 of the Purchase Agreement to Schedule I (which investors shall be included in the definition of “Investors” hereunder upon executing and delivering to the Company a signature page to the Purchase
Agreement). Notwithstanding the foregoing, (i) a waiver or consent to depart from the provisions hereof with respect to a matter that relates exclusively to the rights of Holders whose securities are being sold pursuant to a Registration
Statement and that does not directly or indirectly affect, impair, limit or compromise the rights of other Holders may be given by Holders of at least a majority of the Registrable Securities being sold by such Holders pursuant to such Registration
Statement and (ii) this Agreement may not be amended, modified, changed, waived, discharged or terminated and the observance of any term hereunder may not be waived with respect to any Holder without the written consent of such Holder if such
amendment, modification, waiver, discharge or termination uniquely applies to such Holder; provided, however, that the provisions of this sentence may not be amended, modified or supplemented except in accordance with the provisions of
the immediately preceding sentence. No amendment, modification or discharge of this Agreement, and no waiver hereunder, shall be valid or binding unless set forth in writing. Any such waiver shall constitute a waiver only with respect to the
specific matter described in such writing and shall in no way impair the rights of the party or parties granting such waiver in any other respect or at any other time. 

4.3 Successors, Assigns and Transferees. 

(a) This Agreement shall be binding upon and shall inure to the benefit of the parties hereto and their respective permitted
successors, assigns and transferees. Any Holder may assign its rights applicable to the shares transferred hereunder to: 

(i) successors, assigns and transferees of such Holder by merger or consolidation or otherwise by operation of law, 

(ii) any transferee who acquires at least 20% of the Registrable Securities owned by a transferring Holder; or 

(iii) any partner, member or stockholder or other Affiliate of a Holder. 

(b) In addition, such assignment is conditioned upon: (i) such Investor or other Holder agreeing in writing with the
transferee or assignee to assign such rights, and the Issuer receiving written notice from the assigning party at the time of such assignment stating the name and address of the assignee and identifying the capital stock of the Issuer as to which
the rights in question are being assigned; and (ii) the transferee or assignee agreeing in writing to be bound by all of the terms and conditions of this Agreement. 

4.4 Notices. Any notice required to be given hereunder shall be sufficient if in writing, and sent by facsimile
