    	2

    	 

    

 

 

1.2          Demand
Registration.

 

(a)          If
the Company shall receive at any time not earlier than the earlier of (i) four (4) years after the date of this Agreement
and (ii) six (6) months after the effective date of the first registration statement for a public offering of securities of
the Company (other than a registration statement relating either to the sale of securities to employees of the Company pursuant
to a stock option, stock purchase or similar plan or a transaction pursuant to Rule 145 under the Act) a written request from the
Series F Requisite Investors (as defined in the Purchase Agreement), that the Company register for sale under the Act all or any
portion of the shares of Registrable Securities held by such Holders having an aggregate anticipated price to the public (before
any underwriters’ discounts or commissions) of not less than $5,000,000:

 

 (i)          within ten (10) days after the receipt thereof, give written notice of such request to all Holders; and

 

(ii)         use
its reasonable best efforts to file as soon as practicable the registration under the Act of all Registrable Securities which the
Holders request to be registered, subject to the limitations of Section 1.2(b).

 

(b)          If
the Holders initiating the registration request hereunder (“Initiating Holders”) intend to distribute
the Registrable Securities covered by their request by means of an underwriting, they shall so advise the Company as a part of
their request made pursuant to Section 1.2(a) and the Company shall include such information in the written notice referred to
in Section 1.2(a). The underwriter will be selected by the Company and shall be reasonably acceptable to a majority in interest
of the Initiating Holders. In such event, the right of any Holder to include its Registrable Securities in such registration shall
be conditioned upon such Holder’s participation in such underwriting and the inclusion of such Holder’s Registrable
Securities in the underwriting (unless otherwise mutually agreed by a majority in interest of the Initiating Holders and such Holder)
to the extent provided herein. All Holders proposing to distribute their securities through such underwriting shall (together with
the Company as provided in Section 1.4(e)) enter into an underwriting agreement in customary form with the underwriter or underwriters
selected for such underwriting. Notwithstanding any other provision of this Section 1.2, if the underwriter advises the Initiating
Holders in writing that marketing factors require a limitation of the number of shares to be underwritten, then the Initiating
Holders shall so advise all Holders of Registrable Securities which would otherwise be underwritten pursuant to this Agreement,
and the number of shares of Registrable Securities that may be included in the underwriting shall be allocated among all Holders,
including the Initiating Holders, in proportion (as nearly as practicable) to the amount of Registrable Securities of the Company
owned by each Holder; provided, however, that the number of shares of Registrable Securities to be included in such underwriting
shall not be reduced unless all other securities are first entirely excluded from the underwriting. For purposes of the preceding
sentence concerning allocation, for any Holder that is a partnership or corporation, the partners, retired partners and stockholders
of such Holder, or the estates and family members of any such partners and retired partners and any trusts for the benefit of any
of the foregoing persons shall be deemed to be a single “Holder”, and any pro rata reduction with respect to
such Holder shall be based upon the aggregate amount of shares carrying registration rights owned by all entities and individuals
included in such “Holder”, as defined in this sentence.

 

(c)          Notwithstanding
the foregoing, if the Company shall furnish to Holders requesting a registration statement pursuant to this Section 1.2, a
certificate signed by the Chief Executive Officer of the Company stating that in the good faith judgment of the Board of Directors
of the Company, it would be detrimental to the Company and its stockholders for such registration statement to be filed and the
filing of such registration statement should therefore be delayed, the Company shall have the right to delay taking action with
respect to such filing for two periods of not more than sixty (60) days each in any twelve (12) month period after receipt of the
request of the Initiating Holders.

 

 

    	3

    	 

    

 

(d)          In
addition, the Company shall not be obligated to effect, or to take any action to effect, any registration pursuant to this Section 1.2:

 

(i)          After
the Company has effected two registrations pursuant to this Section 1.2 and such registrations have been declared or ordered
effective;

 

(ii)         During
the period starting with the date sixty (60) days prior to the Company’s good faith estimate of the date of filing of, and
ending on a date one hundred eighty (180) days after the effective date of, a registration subject to Section 1.3 hereof;
provided that the Company is actively employing in good faith all reasonable efforts to cause the Section 1.3 registration
statement to become effective; or

 

(iii)        If
the Initiating Holders propose to dispose of shares of Registrable Securities that may be immediately registered on Form S-3 pursuant
to a request made pursuant to Section 1.12 below.

 

1.3           Company
Registration. If (but without any obligation to do so) the Company proposes to register (including
for this purpose a registration effected by the Company for stockholders other than the Holders) any of its stock or other securities
under the Act in connection with the public offering of such securities solely for cash (other than a registration relating solely
to the sale of securities to participants in a Company stock plan, a registration on any form which does not include substantially
the same information as would be required to be included in a registration statement covering the sale of the Registrable Securities
or a registration in which the only Common Stock being registered is Common Stock issuable upon conversion of debt securities which
are also being registered), the Company shall, at such time, promptly give each Holder written notice of such registration. Upon
the written request of each Holder given within twenty (20) days after the giving of such notice by the Company in accordance with
Section 3.5, the Company shall, subject to the provisions of Section 1.8, cause to be registered under the Act all or
part of the Registrable Securities that each such Holder has requested to be registered. If a Holder decides not to include all
of its Registrable Securities in any registration statement thereafter filed by the Company, such Holder shall nevertheless continue
to have the right to include any Registrable Securities in any subsequent registration statement or registration statements as
may be filed by the Company with respect to offerings of its securities, all upon the terms and conditions set forth herein. Any
Holder who elects to include some or all of its Registrable Securities pursuant to this Section 1.3 shall cooperate with the
Company in the preparation of any and all documents and instruments the Company deems necessary or convenient for the preparation
of any applicable registration statement, and such Holder shall supply the Company with any and all information the Company deems
necessary or convenient with respect to any such registration statement.

 

    	4

    	 

    

 

1.4           Obligations
of the Company. Whenever required under this Section 1 to effect the registration of any
Registrable Securities, the Company shall, as expeditiously as reasonably practicable:

 

 (a)          Prepare
and file with the SEC a registration statement with respect to such Registrable Securities and use its reasonable best efforts
to cause such registration statement to become effective, and, upon the request of the Holders of a majority of the Registrable
Securities registered thereunder, keep such registration statement effective for a period of up to one hundred twenty (120) days
or until the distribution contemplated in the Registration Statement has been completed; provided, however, that (i) such
120-day period shall be extended for a period of time equal to the period the Holder refrains from selling any securities included
in such registration at the request of an underwriter of Common Stock (or other securities) of the Company; and (ii) in the
case of any registration of Registrable Securities on Form S-3 which are intended to be offered on a continuous or delayed basis,
such 120-day period shall be extended, if necessary, to keep the registration statement effective until the majority of such Registrable
Securities are sold, provided that Rule 415 under the Act, or any successor rule under the Act, permits an offering on a continuous
or delayed basis, and provided further that applicable rules under the Act governing the obligation to file a post-effective amendment
permit, in lieu of filing a post-effective amendment which (I) includes any prospectus required by Section 5 of the Act or
(II) reflects facts or events representing a material or fundamental change in the information set forth in the registration
statement, the incorporation by reference of information required to be included in (I) and (II) above to be contained in periodic
reports filed pursuant to Section 13 or 15(d) of the 1934 Act in the registration statement.

 

(b)          Prepare
and file with the SEC such amendments and supplements to such registration statement and the prospectus used in connection with
such registration statement as may be necessary to comply with the provisions of the Act with respect to the disposition of all
securities covered by such registration statement.

 

(c)          Furnish
to the Holders such numbers of copies of a prospectus, including a preliminary prospectus, in conformity with the requirements
of the Act, and such other documents as they may reasonably request in order to facilitate the disposition of Registrable Securities
owned by them.

 

(d)          Use
its reasonable best efforts to register and qualify the securities covered by such registration statement under such other securities
or Blue Sky laws of such jurisdictions as shall be reasonably requested by the Holders; provided that the Company shall not be
required in connection therewith or as a condition thereto to qualify to do business or to file a general consent to service of
process in any such states or jurisdictions.

 

(e)          In
the event of any underwritten public offering, enter into and perform its obligations under an underwriting agreement, in usual
and customary form, with the managing underwriter of such offering. Each Holder participating in such underwriting shall also enter
into and perform its obligations under such an agreement.

 

(f)          Notify
each Holder of Registrable Securities covered by such registration statement at any time when a prospectus relating to the registration
statement is required to be delivered under the Act of the happening of any event as a result of which 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 not misleading in the light of the circumstances
then existing.

 

    	5

    	 

    

  

(g)          Cause
all such Registrable Securities registered pursuant to this Agreement to be listed on each securities exchange on which similar
securities issued by the Company are then listed.

 

(h)          Provide
a transfer agent and registrar for all Registrable Securities registered pursuant to this Agreement and a CUSIP number for all
such Registrable Securities, in each case not later than the effective date of such registration.

 

(i)          Use
its reasonable best efforts to furnish, at the request of any Holder requesting registration of Registrable Securities, on the
date that such Registrable Securities are delivered to the underwriters for sale, if such securities are being sold through underwriters
or, if such securities are not being sold through underwriters, on the date that the registration statement with respect to such
securities becomes effective, (i) an opinion, dated as of such date, of the counsel representing the Company for the purposes of
such registration, in form and substance as is customarily given to underwriters in an underwritten public offering, or if not
underwritten, in form and substance as is customarily given to underwriters and reasonably satisfactory to counsel to the Holder
offering the greatest number of Registrable Securities for sale in the registration, addressed to the underwriters, if any, and
to the Holders requesting registration of Registrable Securities, and (ii) a “comfort” letter dated as of such
date, from the independent certified public accountants of the Company, in form and substance as is customarily given by independent
certified public accountants to underwriters in an underwritten public offering, or if not underwritten, in form and substance
as is customarily given to underwriters and reasonably satisfactory to counsel to the Holder offering the greatest number of Registrable
Securities for sale in the registration, addressed to the underwriters, if any, and to the Holders requesting registration of Registrable
Securities.

 

1.5          Furnish
Information.

 

(a)          It
shall be a condition precedent to the obligations of the Company to take any action pursuant to this Section 1 with respect
to the Registrable Securities of any selling Holder that such Holder shall furnish to the Company such information regarding itself,
the Registrable Securities held by it, and the intended method of disposition of such securities as shall be required to effect
the registration of such Holder’s Registrable Securities.

 

(b)          The
Company shall have no obligation with respect to any registration requested pursuant to Section 1.2 or Section 1.12 if, due
to the operation of Section 1.5(a), the number of shares or the anticipated aggregate offering price of the Registrable Securities
to be included in the registration does not equal or exceed the number of shares or the anticipated aggregate offering price required
to originally trigger the Company’s obligation to initiate such registration as specified in Section 1.2(a) or Section 1.12(b)(2),
whichever is applicable.

 

1.6          Expenses
of Demand Registration. All expenses other than underwriting discounts and commissions incurred
in connection with registrations, filings or qualifications pursuant to Section 1.2, including (without limitation) all registration,
filing and qualification fees, printers’ and accounting fees, fees and disbursements of one (1) special counsel for the selling
Holders and another counsel for the Company shall be borne by the Company; provided, however, that the Company shall not
be required to pay for any expenses of any registration proceeding begun pursuant to Section 1.2 if the registration request
is subsequently withdrawn at the request of a majority–in–interest of the Initiating Holders (in which case all participating
Holders shall bear such expenses), unless such Initiating Holders agree to forfeit (on behalf of all Holders) the right to one
demand registration pursuant to Section 1.2; provided further, however, that if at the time of such withdrawal, the
Holders have learned of a material adverse change in the condition, business, or prospects of the Company not previously known
to the Holders at the time of their request and have withdrawn the request with reasonable promptness following disclosure by the
Company of such material adverse change, then the Holders shall not be required to pay any of such expenses and will not be required
to forfeit any such right pursuant to Section 1.2.

 

    	6

    	 

    

  

1.7           Expenses
of Company Registration. The Company shall bear and pay all expenses incurred in connection with
any registration, filing or qualification of Registrable Securities with respect to the registrations pursuant to Section 1.3
for each Holder (which right may be assigned as provided in Section 1.13), including (without limitation) all registration, filing,
and qualification fees, printers and accounting fees relating or apportionable thereto, but excluding underwriting discounts and
commissions relating to Registrable Securities.

 

1.8           Underwriting
Requirements. In connection with any offering involving an underwriting of shares of the Company’s
capital stock, the Company shall not be required under Section 1.3 to include any of the Holders’ securities in such
underwriting unless they accept the terms of the underwriting as agreed upon between the Company and the underwriters selected
by the Company (or by other persons entitled to select the underwriters), and then only in such quantity as the underwriters determine
in good faith and in their sole discretion will not, because of marketing factors, jeopardize the success of the offering by the
Company. If the total amount of securities, including Registrable Securities, requested by stockholders to be included in such
offering exceeds the amount of securities that the underwriters determine in good faith and in their sole discretion is compatible
with the success of the offering, then the Company shall be required to include in the offering only that number of such securities
which the underwriters determine in their sole discretion will not, because of marketing factors, jeopardize the success of the
offering (the securities so included to be allocated and apportioned first, to the Company; second, pro rata among the selling
Holders according to the total amount of Registrable Securities owned by each such Holder or in such other proportion as shall
be mutually agreed to by such Holders; and third, pro rata among any other selling stockholders according to the total amount
of securities owned by each such selling stockholder or in such other proportion as shall mutually be agreed to by such selling
stockholders) but in no event shall the amount of securities of the selling Holders included in the offering be reduced below thirty
percent (30%) of the total amount of securities included in such offering, unless such offering is the initial public offering
of the Company’s securities, in which case all selling Holders and other selling stockholders may be excluded if the Company
and underwriters make the determination described above. For purposes of the preceding parenthetical concerning allocation and
apportionment, for any Holder or selling stockholder that is a partnership or corporation, the partners, retired partners and stockholders
of such Holder or selling stockholder, or the estates and family members of any such partners and retired partners and any trusts
for the benefit of any of the foregoing persons shall be deemed to be a single “Holder” or “selling stockholder”,
as applicable, and any pro rata reduction with respect to such Holder or selling stockholder shall be based upon the aggregate
amount of shares carrying registration rights owned by all entities and individuals included in such “Holder” or “selling
stockholder”, as defined in this sentence.

 

    	7

    	 

    

 

1.9           Delay
of Registration. No Holder shall have any right to obtain or seek an injunction restraining or
otherwise delaying any such registration as the result of any controversy that might arise with respect to the interpretation or
implementation of this Section 1.

 

1.10         Indemnification.
In the event any Registrable Securities are included in a registration statement under this Section 1:

  

(a)          To
the extent permitted by applicable federal and state law, the Company will indemnify and hold harmless each Holder, any underwriter
(as defined in the Act) for such Holder and each person, if any, who controls such Holder or underwriter within the meaning of
the Act or the 1934 Act, against any losses, claims, damages, or liabilities (joint or several) to which they may become subject
under the Act, the 1934 Act or other federal or state law, insofar as such losses, claims, damages, or liabilities (or actions
in respect thereof) arise out of or are based upon any of the following statements, omissions or violations (collectively a “Violation”):
(i) any untrue statement or alleged untrue statement of a material fact contained in such registration statement, including any
preliminary prospectus or final prospectus contained therein or any amendments or supplements thereto, (ii) the 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 or alleged violation by the Company of the Act, the 1934 Act, any state securities law or any rule or regulation
promulgated under the Act, the 1934 Act or any state securities law; and the Company will pay to each such Holder, underwriter
or controlling person, any legal or other expenses reasonably incurred by them in connection with investigating or defending any
such loss, claim, damage, liability, or action; provided, however, that the indemnity agreement contained in this Section
1.10(a) shall not apply to amounts paid in settlement of any such loss, claim, damage, liability, or action if such settlement
is effected without the consent of the Company (which consent shall not be unreasonably withheld), nor shall the Company be liable
in any such case for any such loss, claim, damage, liability, or action to the extent that it arises out of or is based upon a
Violation which occurs in reliance upon and in conformity with written information furnished expressly for use in connection with
such registration by any such Holder, underwriter or controlling person.

 

(b)          To
the extent permitted by law, each selling Holder will indemnify and hold harmless the Company, each of its directors, each of its
officers who has signed the registration statement, each person, if any, who controls the Company within the meaning of the Act,
any underwriter, any other Holder selling securities in such registration statement and any controlling person of any such underwriter
or other Holder, against any losses, claims, damages, or liabilities (joint or several) to which any of the foregoing persons may
become subject, under the Act, the 1934 Act or other federal or state law, insofar as such losses, claims, damages, or liabilities
(or actions in respect thereto) arise out of or are based upon any Violation, in each case to the extent (and only to the extent)
that such Violation occurs in reliance upon and in conformity with written information furnished by such Holder expressly for use
in connection with such registration; and each such Holder will pay any legal or other expenses reasonably incurred by any person
intended to be indemnified pursuant to this Section 1.10(b), in connection with investigating or defending any such loss, claim,
damage, liability, or action; provided, however, that the indemnity agreement contained in this Section 1.10(b) shall not
apply to amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without
the consent of the Holder, which consent shall not be unreasonably withheld; provided, that, in no event shall any indemnity under
this Section 1.10(b) exceed the net proceeds from the offering received by such Holder.

 

    	8

    	 

    

 

(c)          Promptly
after receipt by an indemnified party under this Section 1.10 of notice of the commencement of any action (including any governmental
action), such indemnified party will, if a claim in respect thereof is to be made against any indemnifying party under this Section
1.10, deliver to the indemnifying party a written notice of the commencement thereof and the indemnifying party shall have the
right to participate in, and, to the extent the indemnifying party so desires, jointly with any other indemnifying party similarly
noticed, to assume the defense thereof with counsel mutually satisfactory to the parties; provided, however, that an indemnified
party (together with all other indemnified parties which may be represented without conflict by one counsel) shall have the right
to retain one separate counsel, with the fees and expenses to be paid by the indemnifying party, if representation of such indemnified
party by the counsel retained by the indemnifying party would be inappropriate due to actual or potential differing interests between
such indemnified party and any other party represented by such counsel in such proceeding. The failure to deliver written notice
to the indemnifying party within a reasonable time of the commencement of any such action, if prejudicial to its ability to defend
such action, shall relieve such indemnifying party of any liability to the indemnified party under this Section 1.10, but the omission
so to deliver written notice to the indemnifying party will not relieve it of any liability that it may have to any indemnified
party otherwise than under this Section 1.10.

  

(d)          If
the indemnification provided for in this Section 1.10 is held by a court of competent jurisdiction to be unavailable to an indemnified
party with respect to any loss, liability, claim, damage, or expense referred to therein, then the indemnifying party, in lieu
of indemnifying such indemnified party hereunder, shall contribute to the amount paid or payable by such indemnified party as a
result of such loss, liability, claim, damage, or expense 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 loss, liability, claim, damage, or expense as well as any other relevant equitable considerations. The relative
fault of the indemnifying party and of the indemnified party shall be determined by reference to, among other things, whether the
untrue or alleged untrue statement of a material fact or the omission to state a material fact relates to information supplied
by the indemnifying party or by the indemnified party and the parties’ relative intent, knowledge, access to information,
and opportunity to correct or prevent such statement or omission. Notwithstanding the provisions of this paragraph of Section 1.10,
in no case shall any one Holder be liable or responsible for any amount in excess of the net proceeds received by such Holder from
the offering of Registrable Securities; provided, however, that no person guilty of fraudulent misrepresentation (within
the meaning of Section 11(f) of the Act) shall be entitled to contribution for any person who was not guilty of such fraudulent
misrepresentation. Any party entitled to contribution will, promptly after receipt of notice of commencement of any action, suit
or proceeding against such party or parties under this Section, notify such party or parties from whom such contribution may be
sought, but the omission so to notify such party or parties from contribution may be sought shall not relieve such party from any
other obligation it or they may have thereunder or otherwise under this Section. No party shall be liable for contribution with
respect to any action, suit, proceeding or claim settled without its prior written consent, which consent shall not be unreasonably
withheld.

 

    	9

    	 

    

  

(e)          Notwithstanding
the foregoing, to the extent that the provisions on indemnification and contribution contained in the underwriting agreement entered
into in connection with the underwritten public offering are in conflict with the foregoing provisions, the provisions in the underwriting
agreement shall control.

 

(f)          The
obligations of the Company and Holders under this Section 1.10 shall survive the completion of any offering of Registrable Securities
in a registration statement under this Section 1, and otherwise.

 

1.11        Reports
Under Securities Exchange Act of 1934. With a view to making available to the Holders the benefits
of Rule 144 promulgated under the Act (“Rule 144”) and any other rule
or regulation of the SEC that may at any time permit a Holder to sell securities of the Company to the public without registration
or pursuant to a registration on Form S-3, the Company agrees to:

 

(a)          make
and keep public information available, as those terms are understood and defined in Rule 144, at all times after ninety (90) days
after the effective date of the first registration statement filed by the Company for the offering of its securities to the general
public;

 

(b)          file
with the SEC in a timely manner all reports and other documents required of the Company under the Act and the 1934 Act; and

 

(c)          furnish
to any Holder, so long as the Holder owns any Registrable Securities, forthwith upon request (i) a written statement by the Company
that it has complied with the reporting requirements of Rule 144 (at any time after ninety (90) days after the effective date of
the first registration statement filed by the Company), the Act and the 1934 Act (at any time after it has become subject to such
reporting requirements), or that it qualifies as a registrant whose securities may be resold pursuant to Form S-3 (at any time
after it so qualifies), (ii) a copy of the most recent annual or quarterly report of the Company and such other reports and documents
so filed by the Company, and (iii) such other information as may be reasonably requested in availing any Holder of any rule or
regulation of the SEC which permits the selling of any such securities without registration or pursuant to such form.

 

1.12        Form
S-3 Registration. In case the Company shall receive from any Holder or Holders of Registrable
Securities issued upon conversion of the Preferred Stock then outstanding a written request or requests that the Company effect
a registration on Form S-3 and any related qualification or compliance with respect to all or a part of the Registrable Securities
owned by such Holder or Holders, the Company will: 

 

(a)          promptly
give written notice of the proposed registration, and any related qualification or compliance, to all other Holders; and

 

    	10

    	 

    

 

(b)          as
soon as practicable, effect such registration and all such qualifications and compliances as may be so requested and as would permit
or facilitate the sale and distribution of all or such portion of such Holder’s or Holders’ Registrable Securities
as are specified in such request, together with all or such portion of the Registrable Securities of any other Holder or Holders
joining in such request as are specified in a written request given within 15 days after giving of such written notice by the Company;
provided, however, that the Company shall not be obligated to effect any such registration, qualification or compliance,
pursuant to this Section 1.12: (1) if Form S-3 is not available for such offering by the Holders; (2) if the Holders,
together with the holders of any other securities of the Company entitled to inclusion in such registration, propose to sell Registrable
Securities and such other securities (if any) at an aggregate price to the public (before any underwriters’ discounts or
commissions) of less than $2,500,000; (3) if the Company shall furnish to the Holders a certificate signed by the President
of the Company stating that in the good faith judgment of the Board of Directors of the Company, it would be seriously detrimental
to the Company and its stockholders for such Form S-3 registration to be effected at such time, in which event the Company shall
have the right to defer the filing of the Form S-3 registration statement for one (1) period of not more than ninety (90) days
after receipt of the request of the Holder or Holders under this Section 1.12 in any twelve (12) month period, provided that the
Company shall not register any other of its securities during such ninety (90) day period other than pursuant to a Special Registration
Statement (as defined below); (4) if the Company has already effected one (1) registration on Form S-3 within the preceding
six (6) months; or (5) in any particular jurisdiction in which the Company would be required to qualify to do business or
to execute a general consent to service of process in effecting such registration, qualification or compliance.

  

(c)          Subject
to the foregoing, the Company shall file a registration statement covering the Registrable Securities and other securities so requested
to be registered as soon as practicable after receipt of the request or requests of the Holders. All expenses incurred in connection
with a registration requested pursuant to Section 1.12, including (without limitation) all registration, filing, qualification,
printer’s and accounting fees and the reasonable fees and disbursements of one (1) special counsel for the selling Holder
or Holders and another counsel for the Company, shall be borne by the Company; provided that following such time as the Company
has effected two (2) registrations on Form S-3 pursuant to this Section 1.12 during any consecutive twelve (12) month period, all
expenses incurred in connection with any further Form S-3 registrations effected pursuant to this Section 1.12 during such period
shall be borne pro rata by the Holder or Holders participating in the Form S-3 registration. Registrations effected pursuant to
this Section 1.12 shall not be counted as demands for registration or registrations effected pursuant to Sections 1.2 or 1.3, respectively.

 

1.13         Assignment
of Registration Rights. The rights to cause the Company to register Registrable Securities pursuant
to this Section 1 may be assigned (but only with all related obligations) by a Holder to (i) any partner or retired partner
of any Holder which is a partnership, (ii) any family member or trust for the benefit of any individual Holder or any such
family member, or (iii) any transferee or assignee (other than a competitor of the Company, as determined in good faith by
the Company’s Board of Directors) who acquires at least 25,000 shares of Registrable Securities (as adjusted for stock splits,
dividends, recapitalizations and the like with respect to such shares) provided: (a) the Company is, within a reasonable time
after such transfer, furnished with written notice of the name and address of such transferee or assignee and the securities with
respect to which such registration rights are being assigned; (b) such transferee or assignee agrees in writing to be bound
by and subject to the terms and conditions of this Agreement, including without limitation the provisions of Section 1.15 below;
and (c) such assignment shall be effective only if immediately following such transfer the further disposition of such securities
by the transferee or assignee is restricted under the Act. 

 

    	11

    	 

    

  

1.14        “Market
Stand-Off” Agreement. Each Investor hereby agrees that, during the period of duration specified
by the Company and an underwriter of Common Stock or other securities of the Company, following the effective date of a registration
statement of the Company filed under the Act in connection with the Company’s initial public offering, it shall not, to the
extent requested by the Company and such underwriter, directly or indirectly sell, offer to sell, contract to sell (including,
without limitation, any short sale), grant any option to purchase or otherwise transfer or dispose of (other than to donees who
agree to be similarly bound, effective immediately upon the transfer of securities to any such donees) any securities of the Company
held by it at any time during such period except Common Stock included in such registration; provided, however, that:

 

(a)          such
agreement shall not exceed one hundred eighty (180) days (or such longer period, not to exceed 18 days after the expiration of
the 180-day period, as the underwriters or the Company shall request in order to facilitate compliance with NASD Rule 2711) following
the effective date of such registration statement of the Company filed under the Act; and

 

(b)          all
executive officers and directors of the Company then holding Common Stock and each stockholder of the Company holding in the aggregate
at least 1% of the Company's equity securities on a fully-diluted basis (whether or not pursuant to this Agreement) enter into
similar agreements; provided, however, that all restrictions set forth in this Section 1.14 on all such Investors shall
terminate and be of no further force or effect if any such officer or director or any such stockholder is released from, or otherwise
no longer bound by, such restrictions.

 

In order to enforce the foregoing covenant,
the Company may place restrictive legends on the certificates representing, and impose stop-transfer instructions with respect
to, the Registrable Securities of the Investor (and the shares or securities of every other person subject to the foregoing restriction)
until the end of such period. Notwithstanding the foregoing, the obligations described in this Section 1.14 shall not apply to
a registration relating solely to employee benefit plans on Form S-l or Form S-8 or similar forms which may be promulgated in the
future, or a registration relating solely to a Commission Rule 145 transaction on Form S-4 or similar forms which may be promulgated
in the future (a “Special Registration Statement”).

 

1.15       Termination
of Registration Rights.

 

(a)          No
Holder shall be entitled to exercise any right provided for in this Section 1 after five (5) years following the consummation
of the sale of securities pursuant to a registration statement filed by the Company under the Act in connection with the initial
firm commitment underwritten offering of its securities to the general public, in connection with which all shares of Preferred
Stock convert into Common Stock.

 

    	12

    	 

    

 

(b)          In
addition, the right of any Holder to request registration or inclusion in any registration pursuant to Section 1.3 shall terminate
on the closing of the first Company-initiated registered public offering of Common Stock of the Company if all shares of Registrable
Securities held or entitled to be held upon conversion by such Holder may immediately be sold under Rule 144 during any 90-day
period, or on such date after the closing of the first Company-initiated registered public offering of Common Stock of the Company
as all shares of Registrable Securities held or entitled to be held upon conversion by such Holder may immediately be sold under
Rule 144 during any 90-day period.

  

1.16         Limitation
on Subsequent Registration Rights. After the date of this Agreement, the Company shall not, without
the prior written consent of the Series F Requisite Investors, enter into any agreement with any holder or prospective holder of
any securities of the Company that would grant such holder registration rights on a parity with or senior to those granted to the
Holders hereunder, other than the right to a Special Registration Statement.

 

SECTION
2.          COVENANTS OF THE COMPANY.

 

2.1           Delivery
of Financial Statements and Annual Operating Budget. Subject to Section 2.3, upon request
the Company shall deliver to each Investor that holds a minimum aggregate of 500,000 shares of Preferred Stock (as adjusted for
stock splits, dividends, recapitalizations and the like with respect to such shares) (a “Major Investor”),
as soon as practicable:

 

(a)          but
not later than 120 days following the end of each fiscal year of the Company, an income statement for such fiscal year, a balance
sheet of the Company and statement of stockholder’s equity as of the end of such fiscal year, and a schedule as to the sources
and applications of funds for such fiscal year, such fiscal year-end financial reports to be in reasonable detail, prepared in
accordance with generally accepted accounting principles, and audited and certified by independent public accountants selected
by the Company’s Board of Directors, including at least one of the Series F Directors (as such term is defined in the Company’s
Amended and Restated Certificate of Incorporation as in effect from time to time (the “Restated Certificate”));

 

(b)          but
not later than 45 days following the end of each fiscal year of the Company, a preliminary unaudited income statement for such
fiscal year, and a preliminary unaudited balance sheet of the Company and a preliminary unaudited statement of stockholder’s
equity as of the end of such fiscal year;

 

(c)          but
not later than 30 days following the end of each calendar month or fiscal quarter of the Company, unaudited financial statements
of the Company for such month or fiscal quarter; and

 

(d)          but
not later than 30 days before the beginning of each fiscal year of the Company, an annual operating budget of the Company for such
fiscal year, which shall be approved by the Company’s Board of Directors prior to the commencement of such fiscal year.

 

2.2           Inspection.
Subject to Section 2.3, the Company shall permit each Investor, at such Investor’s expense,
to visit and inspect the Company’s properties, to examine its books of account and records and to discuss the Company’s
affairs, finances and accounts with its officers, all at such reasonable times as may be requested by the Investor; provided,
however, that the Company shall not be obligated pursuant to this Section 2.2 to provide access to any information which
it reasonably considers to be a trade secret or similar confidential information. 

 

    	13

    	 

    

  

2.3           Confidentiality;
Assignment of Information and Inspection Rights. Each Investor agrees to use the same degree
of care as such Investor uses to protect its own confidential information to keep confidential any information furnished to such
Investor (including pursuant to Sections 2.1 and 2.2) that the Company marks as being confidential or proprietary (so long as such
information is not in the public domain), except that such Investor may disclose such proprietary or confidential information (i)
to any partner, member, subsidiary, parent, affiliate, advisor, attorney, accountant or auditor of such Investor as long as such
partner, member, subsidiary, parent or affiliate is advised of the confidentiality provisions of this Section 2.3, (ii) at
such time as it enters the public domain through no fault of such Investor, (iii) that is communicated to it free of any obligation
of confidentiality or (iv) that is developed by Investor or its agents independently of and without reference to any confidential
information communicated by the Company. Each Investor may release without liability of any kind any information in its possession
if such release is pursuant to a valid order of a court or other government body of the United States or any state thereof; provided
that such Investor provides the Company with reasonable prior written notice of such disclosure and makes a reasonable effort
to obtain, or to assist the Company in obtaining, a protective order preventing or limiting the disclosure and/or requiring that
the confidential information so disclosed be used only for the purposes for which the law or regulation required, or for which
the order was issued. Notwithstanding the foregoing, the terms of the Financing shall not be considered to be confidential or proprietary.
The information and inspection rights set forth in Sections 2.1 and 2.2 may not be assigned or transferred other than to affiliates
of an Investor.

 

2.4           Approval
of Related Party Transactions. After the date of this Agreement, the Company shall not, without
the approval of a majority of the disinterested members of the Board of Directors of the Company (to the extent applicable, including
the affirmative vote or written consent of each of the Preferred Directors (as such term is defined in the Restated Certificate)),
authorize or enter into any transaction with any director or officer of the Company, such director’s or officer’s affiliates
or immediate family members, or the spouses of or trusts or other entities formed solely for the benefit of, or controlled by,
such director, officer or immediate family members. 

 

2.5           Insurance
Policies. The Company shall at all times maintain (i) a directors’ and officers’
insurance policy in the amount of at least $5,000,000, which shall include employment practices liability coverage, and (ii) a
“key person” life insurance policy in the amount of at least $1,000,000, naming the Company as beneficiary, for George
Painter.

 

2.6           Assignment
of Right of First Refusal. In the event the Company elects not to exercise any right of first
refusal the Company may have on a proposed transfer of any of the Company’s outstanding capital stock, the Company shall,
to the extent it may do so, assign such right of first refusal to each Investor that holds at least 500,000 shares in the aggregate
of Series C Stock, Series D Stock, Series E Stock and/or Series F Stock (as adjusted for stock splits, dividends, recapitalizations
and the like with respect to such shares) (a “Series C/D/E/F Stock Major Investor”)
no later than 20 days prior to the expiration thereof. In the event of such assignment, each Series C/D/E/F Stock Major Investor
shall have a right to purchase its pro rata portion of the capital stock proposed to be transferred within 10 days following
the date of such assignment. For purposes of the preceding sentence, a Series C/D/E/F Stock Major Investor’s pro rata
portion shall be equal to the product obtained by multiplying (i) the aggregate number of shares proposed to be transferred by
(ii) a fraction, the numerator of which is the number of shares of Common Stock issuable upon conversion of the Series C Stock,
Series D Stock, Series E Stock and Series F Stock held by such Series C/D/E/F Stock Major Investor at the time of the proposed
transfer and the denominator of which is the total number of shares of Common Stock issuable upon conversion of the Series C Stock,
Series D Stock, Series E Stock and Series F Stock held by all Series C/D/E/F Stock Major Investors at the time of such proposed
transfer. If all of the Series C/D/E/F Stock Major Investors do not elect to purchase their full pro rata portion of the
capital stock proposed to be transferred within such 10 day period, each Series C/D/E/F Stock Major Investor who does so elect
shall have the right to acquire its pro rata portion of the unsubscribed shares within the following 10 day period. For
purposes of the preceding sentence, a Series C/D/E/F Stock Major Investor’s pro rata portion shall be determined as
described above, except that the denominator of the fraction described in clause (ii) above shall be the total number of shares
of Common Stock issuable upon conversion of the Series C Stock, Series D Stock, Series E Stock and Series F Stock owned by all
Series C/D/E/F Stock Major Investors who initially elect to purchase their full pro rata portion of the capital stock proposed
to be transferred.

 

    	14

    	 

    

  

2.7           Right
of First Offer. Subject to the terms and conditions specified in this Section 2.7, the Company
hereby grants to each Major Investor a right of first offer with respect to future issuance or sales by the Company of its Shares
(as defined below). A Major Investor shall be entitled to apportion the right of first offer granted under this Agreement among
itself and its partners and affiliates in such proportions as it deems appropriate. Each time the Company proposes to offer any
shares of, or securities convertible into or exercisable or exchangeable for any shares of, any class of its capital stock or any
phantom stock or stock appreciation rights (“Shares”), the Company
shall first make an offering of such Shares to each Major Investor in accordance with the following provisions:

 

(a)          The
Company shall deliver a notice by certified mail (“Notice”) to the Major Investors stating (i) its
bona fide intention to offer such Shares, (ii) the number of such Shares to be offered, and (iii) the price and terms,
if any, upon which it proposes to offer such Shares. If the consideration to be paid by others for the Shares is not cash, the
fair market value of the consideration shall be determined in good faith by the Company's Board of Directors and a reasonably detailed
explanation of such determination of fair market value shall be included in the Notice. All Major Investors electing to participate
in the offering of such Shares shall pay the cash equivalent thereof as so determined.

 

(b)          By
written notification received by the Company within 20 calendar days after giving of the Notice, each Major Investor may elect
to purchase or obtain, at the price and on the terms specified in the Notice, up to that portion of such Shares which equals the
proportion that the number of shares of Common Stock issued and held, including all shares of Common Stock issuable upon conversion
of the Preferred Stock then held, by such Major Investor bears to the total number of shares of Common Stock of the Company then
outstanding (assuming full conversion of all convertible securities) (the “Pro Rata Portion”). The Company
shall promptly, in writing, inform each Major Investor which purchases all the shares available to it (“Fully-Exercising
Investor”) of any other Major Investor’s failure to do likewise (the “Non-Fully Exercising Investor”).
During the ten-day period commencing after such information is given, each Fully-Exercising Investor shall be entitled to obtain
that portion of the Shares not subscribed for by the Major Investors which is equal to the proportion that the number of shares
of Common Stock issued and held, including all shares of Common Stock issuable upon conversion of Preferred Stock then held, by
such Fully-Exercising Investor bears to the total number of shares of Common Stock issued and held, including all shares of Common
Stock issuable upon conversion of the Preferred Stock then held, by all Fully-Exercising Investors who wish to purchase some of
the unsubscribed shares.

 

    	15

    	 

    

  

(c)          If
all Shares are not elected to be obtained as provided in Section 2.7(b), the Company may, for 90 business days following the expiration
of the period provided in Section 2.7(b), offer the remaining unsubscribed portion of such Shares to any person or persons at a
price not less than, and upon terms no more favorable to the offeree than, those specified in the Notice. If the Company does not
enter into an agreement for the sale of the Shares within such period, the right provided hereunder shall be deemed to be revived
and such Shares shall not be offered unless first reoffered to the Major Investors in accordance herewith.

 

(d)          The
right of first offer in this Section 2.7 shall not be applicable to the issuance or sale of (i) (A) up to 7,242,242 shares
of Common Stock (as adjusted for any stock dividends, combinations and splits with respect to such shares of Common Stock) issued
pursuant to the exercise of the stock options granted pursuant to the Company’s 2002 Equity Incentive Plan (as amended, the
“Option Plan”) and outstanding on the date hereof, (B) up to 3,770,584 shares of Common Stock (as adjusted
for any stock dividends, combinations and splits with respect to such shares of Common Stock) issued as restricted stock awards,
or issuable upon exercise of stock options issued or granted after the date hereof pursuant to the Option Plan or (C) shares of
Common Stock issued as restricted stock awards, or issuable upon exercise of stock options issued or granted after the date hereof
pursuant to the Option Plan to the extent that any stock options or restricted stock awards previously granted pursuant to clause
(A) or clause (B) of this Section 2.7(d)(i) are canceled or expire unexercised or are repurchased upon termination of service to
the Company, in each such case, issued to employees, officers, directors or consultants for the primary purpose of soliciting or
retaining their employment or services for the benefit of the Company, (ii) Shares issued upon or after consummation of a
bona fide, firmly underwritten public offering of shares of Common Stock, registered under the Act pursuant to a registration statement
on Form S-1, in connection with which all shares of Preferred Stock convert into Common Stock, (iii) Shares issued pursuant
to the exercise of warrants outstanding as of the date hereof, (iv) Shares issued as acquisition consideration in connection
with a bona fide business acquisition by the Company, whether by merger, consolidation, sale of assets, sale or exchange of stock
or otherwise, if such issuance or sale is approved by the Company’s Board of Directors, (v) Shares in an amount covering
up to 500,000 shares of Common Stock (as adjusted for stock splits, dividends, recapitalizations and the like with respect to such
shares), issued pursuant to any leasing arrangement or debt financing from a bank or similar financial institution, or pursuant
to any research and development or other strategic partnership, licensing or collaborative arrangements and other similar transactions,
if such issuance or sale is approved by the Company’s Board of Directors including the affirmative vote or written consent
of at least one of the Series F Directors (as defined in the Restated Certificate), (vi) Shares issued pursuant to the Purchase
Agreement, (vii) Shares issued upon the exercise of warrants issued pursuant to the Purchase Agreement, (viii) Shares issued upon
conversion of the Preferred Stock or (ix) Shares issued in connection with any stock split or other stock dividend by the Company.

 

    	16

    	 

    

  

(e)          Any
and all rights arising under this Section 2.7 with respect to the issuance or sale of any Shares may be waived, either prospectively
or retrospectively, by the written consent of (i) the Major Investors that hold a majority of the shares of Common Stock issued
or issuable upon conversion of the shares of Series E Stock held by all Major Investors, voting as a separate class, and (ii) the
Series F Requisite Investors, voting as a separate class, and any such waiver shall be effective as to all Major Investors with
such rights under this Section 2.7.

 

2.8           Proprietary
Information and Inventions Agreements. The Company hereby covenants that it shall require each
new officer and employee of the Company and its subsidiaries to enter into and execute a Proprietary Information and Inventions
Agreement in the standard form used by the Company, and that it shall require each new consultant of the Company and its subsidiaries
to enter into and execute an agreement containing similar terms.

 

2.9           Use
of Proceeds. Unless otherwise determined by the Company’s Board of Directors (including
the affirmative vote or written consent of the Series F Directors), the Company shall use the proceeds of the sale of Series F
Stock in all material respects pursuant to the Company’s business plan, including the use of funds schedule and work plan,
provided to the holders of Series F Stock prior to the date hereof. 

 

2.10         Qualified
Small Business Stock. The Company will use reasonable efforts to not take any action that would
cause the Series F Stock to not qualify as “Qualified Small Business Stock” under Section 1202 of the Internal Revenue
Code of 1986, as amended. The Company will use reasonable efforts to comply with the reporting and record keeping requirements
of Section 1202 of the Internal Revenue Code of 1986, as amended, any regulations promulgated thereunder and any similar state
laws and regulations and agrees not to repurchase any stock of the Company if such repurchase would cause such shares not to so
qualify as “Qualified Small Business Stock.”

 

2.11         Stock
Vesting. Unless otherwise approved by the Company’s Board of Directors, including at least
one of the Series F Directors, all stock options, rights to purchase stock and other stock equivalents (collectively, “Stock
Awards”) issued after the date of this Agreement to employees, directors, consultants
and other service providers shall be subject to vesting as follows: (a) twenty-five percent (25%) of such stock shall vest
at the end of the first year following either the date of issuance or the first of the month following such person’s commencement
of service to the Company, and (b) seventy-five percent (75%) of such stock shall vest ratably monthly over the remaining
three (3) years; provided, however, that the vesting of any such stock (including any Stock Award issued on or prior to
the date of this Agreement) may be accelerated upon the approval of the Company’s Board of Directors, including at least
one of the Series F Directors. Any Stock Awards issued after the date of this Agreement shall not be subject to any vesting acceleration
or severance benefits, whether in stock, cash or other form, other than pursuant to the terms of the Option Plan or other employment
agreements or severance agreements in effect as of the date hereof.

 

 

    	17

    	 

    

  

2.12         Management
Carve-Out Plan. As soon as practicable following the Initial Closing, the Company and the Investors
shall take all reasonable steps necessary to implement a management carve-out plan (the “Carve-Out Plan”)
whereby the Company’s management will be entitled to a minimum of ten percent (10%) of the total proceeds available for distribution
to the Company’s stockholders upon the closing of an Acquisition or Asset Transfer (each as defined in the Restated Certificate).
The Carve-Out Plan shall be subject to the approval of the Company’s Board of Directors including the affirmative vote or
written consent of both of the Series F Directors. It is anticipated that the Carve-Out Plan will contain provisions generally
providing for reductions in proceeds payable thereunder based on in-the-money equity awards held by the Company’s management,
the specific terms of which shall be set forth in the Carve-Out Plan.

 

2.13         Termination
of Covenants. The covenants set forth in Sections 2.1 through 2.12 (other than the covenant
set forth in Section 2.3, which shall survive indefinitely) shall terminate and be of no further force or effect upon the earlier
of (i) the consummation of an underwritten public offering of the Company’s Common Stock under the Act in connection with
which all shares of Preferred Stock convert into Common Stock or (ii) the closing of an Asset Transfer or Acquisition. In addition,
the covenants set forth in Sections 2.1 and 2.2 shall terminate and be of no further force or effect in the event the Company otherwise
becomes subject to the periodic reporting requirements of Sections 12(b) or 15(d) of the 1934 Act.

INDEMNITY AGREEMENT

 

This
Indemnity Agreement (this “Agreement”) dated as of ____________________, is made by and between
Chimerix, Inc., a Delaware
corporation (the “Company”), and ____________________________
(“Indemnitee”).

 

Recitals

 

A.           The
Company desires to attract and retain the services of highly qualified individuals as directors, officers, employees and agents.

 

B.           The
Company’s Amended and Restated Bylaws (the “Bylaws”) require that the Company indemnify its directors,
and empowers the Company to indemnify its officers, employees and agents, as authorized by the Delaware General Corporation
Law, as amended (the “DGCL”), under which the Company is organized, and such Bylaws expressly provide
that the indemnification provided therein is not exclusive and contemplates that the Company may enter into separate agreements
with its directors, officers and other persons to set forth specific indemnification provisions.

 

C.           Indemnitee
does not regard the protection currently provided by applicable law, the Company’s governing documents and available insurance
as adequate under the present circumstances, and the Company has determined that Indemnitee and other directors, officers, employees
and agents of the Company may not be willing to serve or continue to serve in such capacities without additional protection.

 

D.           The
Company desires and has requested Indemnitee to serve or continue to serve as a director, officer, employee or agent of the Company,
as the case may be, and has proffered this Agreement to Indemnitee as an additional inducement to serve in such capacity.

 

E.           Indemnitee
is willing to serve, or to continue to serve, as a director, officer, employee or agent of the Company, as the case may be, if
Indemnitee is furnished the indemnity provided for herein by the Company.

 

Agreement

 

Now
Therefore, in consideration of the mutual covenants and agreements set forth herein, the parties hereto, intending to
be legally bound, hereby agree as follows:

 

1.          Definitions.

 

(a)          Agent.
For purposes of this Agreement, the term “agent” of the Company means any person who: (i) is or was a director,
officer, employee or other fiduciary of the Company or a subsidiary of the Company; or (ii) is or was serving at the request
or for the convenience of, or representing the interests of, the Company or a subsidiary of the Company, as a director, officer,
employee or other fiduciary of a foreign or domestic corporation, partnership, joint venture, trust or other enterprise.

 

    	1.

    	 

    

 

(b)          Expenses.
For purposes of this Agreement, the term “expenses” shall be broadly construed and shall include, without limitation,
all direct and indirect costs of any type or nature whatsoever (including, without limitation, all attorneys’, witness, or
other professional fees and related disbursements, and other out-of-pocket costs of whatever nature), actually and reasonably incurred
by Indemnitee in connection with the investigation, defense or appeal of a proceeding or establishing or enforcing a right to indemnification
under this Agreement, the DGCL or otherwise, and amounts paid in settlement by or on behalf of Indemnitee, but shall not include
any judgments, fines or penalties actually levied against Indemnitee for such individual’s violations of law. The term “expenses”
shall also include reasonable compensation for time spent by Indemnitee for which he is not compensated by the Company or any subsidiary
or third party (i) for any period during which Indemnitee is not an agent, in the employment of, or providing services for compensation
to, the Company or any subsidiary; and (ii) if the rate of compensation and estimated time involved is approved by the directors
of the Company who are not parties to any action with respect to which expenses are incurred, for Indemnitee while an agent of,
employed by, or providing services for compensation to, the Company or any subsidiary.

 

(c)          Proceedings.
For purposes of this Agreement, the term “proceeding” shall be broadly construed and shall include, without limitation,
any threatened, pending, or completed action, suit, arbitration, alternate dispute resolution mechanism, investigation, inquiry,
administrative hearing or any other actual, threatened or completed proceeding, whether brought in the right of the Company or
otherwise and whether of a civil, criminal, administrative or investigative nature, and whether formal or informal in any case,
in which Indemnitee was, is or will be involved as a party or otherwise by reason of: (i) the fact that Indemnitee is or was a
director or officer of the Company; (ii) any action taken by Indemnitee or any action on Indemnitee’s part while acting as
director, officer, employee or agent of the Company; or (iii) the fact that Indemnitee is or was serving at the request of the
Company as a director, officer, employee or agent of another corporation, partnership, joint venture, trust, employee benefit plan
or other enterprise, and in any such case described above, whether or not serving in any such capacity at the time any liability
or expense is incurred for which indemnification, reimbursement, or advancement of expenses may be provided under this Agreement.

 

(d)          Subsidiary.
For purposes of this Agreement, the term “subsidiary” means any corporation or limited liability company of which more
than 50% of the outstanding voting securities or equity interests are owned, directly or indirectly, by the Company and one or
more of its subsidiaries, and any other corporation, limited liability company, partnership, joint venture, trust, employee benefit
plan or other enterprise of which Indemnitee is or was serving at the request of the Company as a director, officer, employee,
agent or fiduciary.

 

(e)          Independent
Counsel. For purposes of this Agreement, the term “independent counsel” means a law firm, or a partner (or, if
applicable, member) of such a law firm, that is experienced in matters of corporation law and neither presently is, nor in the
past five (5) years has been, retained to represent: (i) the Company or Indemnitee in any matter material to either such
party, or (ii) any other party to the proceeding giving rise to a claim for indemnification hereunder. Notwithstanding the foregoing,
the term “independent counsel” shall not include any person who, under the applicable standards of professional conduct
then prevailing, would have a conflict of interest in representing either the Company or Indemnitee in an action to determine Indemnitee’s
rights under this Agreement.

 

    	2.

    	 

    

 

2.          Agreement
to Serve. Indemnitee will serve, or continue to serve, as a director, officer, employee or agent of the Company or any subsidiary,
as the case may be, faithfully and to the best of his or her ability, at the will of such corporation (or under separate agreement,
if such agreement exists), in the capacity Indemnitee currently serves as an agent of such corporation, so long as Indemnitee is
duly appointed or elected and qualified in accordance with the applicable provisions of the bylaws or other applicable charter
documents of such corporation, or until such time as Indemnitee tenders his or her resignation in writing; provided, however, that
nothing contained in this Agreement is intended as an employment agreement between Indemnitee and the Company or any of its subsidiaries
or to create any right to continued employment of Indemnitee with the Company or any of its subsidiaries in any capacity.

 

The Company acknowledges
that it has entered into this Agreement and assumes the obligations imposed on it hereby, in addition to and separate from its
obligations to Indemnitee under the Bylaws, to induce Indemnitee to serve, or continue to serve, as a director, officer,
employee or agent of the Company, and the Company acknowledges that Indemnitee is relying upon this Agreement in serving as a director,
officer, employee or agent of the Company.

 

3.          Indemnification.

 

(a)          Indemnification
in Third Party Proceedings. Subject to Section 10 below, the Company shall indemnify Indemnitee to the fullest extent
permitted by the DGCL, as the same may be amended from time to time (but, only to the extent that such amendment permits Indemnitee
to broader indemnification rights than the DGCL permitted prior to adoption of such amendment), if Indemnitee is a party to or
threatened to be made a party to or otherwise involved in any proceeding, for any and all expenses, actually and reasonably incurred
by Indemnitee in connection with the investigation, defense, settlement or appeal of such proceeding.

 

(b)          Indemnification
in Derivative Actions and Direct Actions by the Company. Subject to Section 10 below, the Company shall indemnify Indemnitee
to the fullest extent permitted by the DGCL, as the same may be amended from time to time (but, only to the extent that such amendment
permits Indemnitee to broader indemnification rights than the DGCL permitted prior to adoption of such amendment), if Indemnitee
is a party to or threatened to be made a party to or otherwise involved in any proceeding by or in the right of the Company to
procure a judgment in its favor, against any and all expenses actually and reasonably incurred by Indemnitee in connection with
the investigation, defense, settlement, or appeal of such proceedings.

 

    	3.

    	 

    

 

(c)          Fund
Indemnitors. The Company hereby acknowledges that the Indemnitee has or may have in the future certain rights to indemnification,
advancement of expenses and/or insurance provided by entities and/or organizations other than the Company (collectively, the “Fund
Indemnitors”). In the event that the Indemnitee is, or is threatened to be made, a party to or a participant in any
proceeding to the extent resulting from any claim based on the Indemnitee’s service to the Company as a director or other
fiduciary of the Company, then the Company shall (i) be an indemnitor of first resort (i.e., its obligations to Indemnitee
are primary and any obligation of the Fund Indemnitors to advance expenses or to provide indemnification for the same expenses
or liabilities incurred by Indemnitee are secondary), (ii) be required to advance reasonable expenses incurred by Indemnitee, and
(iii) be liable for the full amount of all expenses, judgments, penalties, fines and amounts paid in settlement to the extent legally
permitted and as required by the terms of this Agreement and any provision of the Bylaws or the Company’s Amended and Restated
Certificate of Incorporation (the “Certificate of Incorporation”) (or any other agreement between the
Company and Indemnitee), without regard to any rights Indemnitee may have against the Fund Indemnitors. The Company irrevocably
waives, relinquishes and releases the Fund Indemnitors from any and all claims against the Fund Indemnitors for contribution, subrogation
or any other recovery of any kind in respect thereof. No advancement or payment by the Fund Indemnitors on behalf of Indemnitee
with respect to any claim for which Indemnitee has sought indemnification from the Company shall affect the foregoing and the Fund
Indemnitors shall have a right of contribution or be subrogated to the extent of such advancement or payment to all of the rights
of recovery of Indemnitee against the Company. The Fund Indemnitors are third party beneficiaries of the terms of this Section.

 

4.          Indemnification
of Expenses of Successful Party. Notwithstanding any other provision of this Agreement, to the extent that Indemnitee has been
successful on the merits or otherwise in defense of any proceeding or in defense of any claim, issue or matter therein, including
the dismissal of any action without prejudice, the Company shall indemnify Indemnitee against all expenses actually and reasonably
incurred in connection with the investigation, defense or appeal of such proceeding.

 

5.          Partial
Indemnification. If Indemnitee is entitled under any provision of this Agreement to indemnification by the Company for some
or a portion of any expenses actually and reasonably incurred by Indemnitee in the investigation, defense, settlement or appeal
of a proceeding, but is precluded by applicable law or the specific terms of this Agreement to indemnification for the total amount
thereof, the Company shall nevertheless indemnify Indemnitee for the portion thereof to which Indemnitee is entitled.

 

6.          Advancement
of Expenses. To the extent not prohibited by law, the Company shall advance the expenses incurred by Indemnitee in connection
with any proceeding, and such advancement shall be made within twenty (20) days after the receipt by the Company of a statement
or statements requesting such advances (which shall include invoices received by Indemnitee in connection with such expenses but,
in the case of invoices in connection with legal services, any references to legal work performed or to expenditures made that
would cause Indemnitee to waive any privilege accorded by applicable law shall not be included with the invoice) and upon request
of the Company, an undertaking to repay the advancement of expenses if and to the extent that it is ultimately determined by a
court of competent jurisdiction in a final judgment, not subject to appeal, that Indemnitee is not entitled to be indemnified by
the Company. Advances shall be unsecured, interest free and without regard to Indemnitee’s ability to repay the expenses.
Advances shall include any and all expenses actually and reasonably incurred by Indemnitee pursuing an action to enforce Indemnitee’s
right to indemnification under this Agreement, or otherwise and this right of advancement, including expenses incurred preparing
and forwarding statements to the Company to support the advances claimed. Indemnitee acknowledges that the execution and delivery
of this Agreement shall constitute an undertaking providing that Indemnitee shall, to the fullest extent required by law, repay
the advance if and to the extent that it is ultimately determined by a court of competent jurisdiction in a final judgment, not
subject to appeal, that Indemnitee is not entitled to be indemnified by the Company. The right to advances under this Section shall
continue until final disposition of any proceeding, including any appeal therein. This Section 6 shall not apply to any claim made
by Indemnitee for which indemnity is excluded pursuant to Section 10(b).

7.          Notice
and Other Indemnification Procedures.

 

(a)          Notification
of Proceeding. Indemnitee will notify the Company in writing promptly upon being served with any summons, citation, subpoena,
complaint, indictment, information or other document relating to any proceeding or matter which may be subject to indemnification
or advancement of expenses covered hereunder. The failure of Indemnitee to so notify the Company shall not relieve the Company
of any obligation which it may have to Indemnitee under this Agreement or otherwise.

 

(b)          Request
for Indemnification and Indemnification Payments. Indemnitee shall notify the Company promptly in writing upon receiving notice
of any demand, judgment or other requirement for payment that Indemnitee reasonably believes to be subject to indemnification under
the terms of this Agreement, and shall request payment thereof by the Company. Indemnification payments requested by Indemnitee
under Section 3 hereof shall be made by the Company no later than sixty (60) days after receipt of the written request of
Indemnitee. Claims for advancement of expenses shall be made under the provisions of Section 6 herein.

 

(c)          Application
for Enforcement. In the event the Company fails to make timely payments as set forth in Sections 6 or 7(b) above, Indemnitee
shall have the right to apply to any court of competent jurisdiction for the purpose of enforcing Indemnitee’s right to indemnification
or advancement of expenses pursuant to this Agreement. In such an enforcement hearing or proceeding, the burden of proof shall
be on the Company to prove that indemnification or advancement of expenses to Indemnitee is not required under this Agreement or
permitted by applicable law. Any determination by the Company (including its Board of Directors, stockholders or independent counsel)
that Indemnitee is not entitled to indemnification hereunder, shall not be a defense by the Company to the action nor create any
presumption that Indemnitee is not entitled to indemnification or advancement of expenses hereunder.

 

(d)          Indemnification
of Certain Expenses. The Company shall indemnify Indemnitee against all expenses incurred in connection with any hearing or
proceeding under this Section 7 unless the Company prevails in such hearing or proceeding on the merits in all material respects.

 

    	5.

    	 

    

 

8.          Assumption
of Defense. In the event the Company shall be requested by Indemnitee to pay the expenses of any proceeding, the Company, if
appropriate, shall be entitled to assume the defense of such proceeding, or to participate to the extent permissible in such proceeding,
with counsel reasonably acceptable to Indemnitee. Upon assumption of the defense by the Company and the retention of such counsel
by the Company, the Company shall not be liable to Indemnitee under this Agreement for any fees of counsel subsequently incurred
by Indemnitee with respect to the same proceeding, provided that Indemnitee shall have the right to employ separate counsel in
such proceeding at Indemnitee’s sole cost and expense. Notwithstanding the foregoing, if Indemnitee’s counsel delivers
a written notice to the Company stating that such counsel has reasonably concluded that there may be a conflict of interest between
the Company and Indemnitee in the conduct of any such defense or the Company shall not, in fact, have employed counsel or otherwise
actively pursued the defense of such proceeding within a reasonable time, then in any such event the fees and expenses of Indemnitee’s
counsel to defend such proceeding shall be subject to the indemnification and advancement of expenses provisions of this Agreement.

 

9.          Insurance.
To the extent that the Company maintains an insurance policy or policies providing liability insurance for directors, officers,
employees, or agents of the Company or of any subsidiary (“D&O Insurance”), Indemnitee shall be covered
by such policy or policies in accordance with its or their terms to the maximum extent of the coverage available for any such director,
officer, employee or agent under such policy or policies. If, at the time of the receipt of a notice of a claim pursuant to the
terms hereof, the Company has D&O Insurance in effect, the Company shall give prompt notice of the commencement of such proceeding
to the insurers in accordance with the procedures set forth in the respective policies. The Company shall thereafter take all necessary
or desirable action to cause such insurers to pay, on behalf of Indemnitee, all amounts payable as a result of such proceeding
in accordance with the terms of such policies.

  

10.         Exceptions.

 

(a)          Certain
Matters. Any provision herein to the contrary notwithstanding, the Company shall not be obligated pursuant to the terms of
this Agreement to indemnify Indemnitee on account of any proceeding with respect to (i) remuneration paid to Indemnitee if
it is determined by final judgment or other final adjudication that such remuneration was in violation of law (and, in this respect,
both the Company and Indemnitee have been advised that the Securities and Exchange Commission believes that indemnification for
liabilities arising under the federal securities laws is against public policy and is, therefore, unenforceable and that claims
for indemnification should be submitted to appropriate courts for adjudication, as indicated in Section 10(d) below); (ii) a
final judgment rendered against Indemnitee for an accounting, disgorgement or repayment of profits made from the purchase or sale
by Indemnitee of securities of the Company against Indemnitee or in connection with a settlement by or on behalf of Indemnitee
to the extent it is acknowledged by Indemnitee and the Company that such amount paid in settlement resulted from Indemnitee's conduct
from which Indemnitee received monetary personal profit, pursuant to the provisions of Section 16(b) of the Securities Exchange
Act of 1934, as amended, or other provisions of any federal, state or local statute or rules and regulations thereunder; (iii) a
final judgment or other final adjudication that Indemnitee’s conduct was in bad faith, knowingly fraudulent or deliberately
dishonest or constituted willful misconduct (but only to the extent of such specific determination); or (iv) on account of conduct
that is established by a final judgment as constituting a breach of Indemnitee’s duty of loyalty to the Company or resulting
in any personal profit or advantage to which Indemnitee is not legally entitled. For purposes of the foregoing sentence, a final
judgment or other adjudication may be reached in either the underlying proceeding or action in connection with which indemnification
is sought or a separate proceeding or action to establish rights and liabilities under this Agreement.

 

    	6.

    	 

    

  

(b)          Claims
Initiated by Indemnitee. Any provision herein to the contrary notwithstanding, the Company shall not be obligated to indemnify
or advance expenses to Indemnitee with respect to proceedings or claims initiated or brought by Indemnitee against the Company
or its directors, officers, employees or other agents and not by way of defense, except (i) with respect to proceedings brought
to establish or enforce a right to indemnification under this Agreement or under any other agreement, provision in the Bylaws or
Certificate of Incorporation or applicable law, or (ii) with respect to any other proceeding initiated by Indemnitee that
is either approved by the Board of Directors or Indemnitee’s participation is required by applicable law. However, indemnification
or advancement of expenses may be provided by the Company in specific cases if the Board of Directors determines it to be appropriate.

 

(c)          Unauthorized
Settlements. Any provision herein to the contrary notwithstanding, the Company shall not be obligated pursuant to the terms
of this Agreement to indemnify Indemnitee under this Agreement for any amounts paid in settlement of a proceeding effected without
the Company’s written consent. Neither the Company nor Indemnitee shall unreasonably withhold consent to any proposed settlement;
provided, however, that the Company may in any event decline to consent to (or to otherwise admit or agree to any liability for
indemnification hereunder in respect of) any proposed settlement if the Company is also a party in such proceeding and determines
in good faith that such settlement is not in the best interests of the Company and its stockholders.

 

(d)          Securities
Act Liabilities. Any provision herein to the contrary notwithstanding, the Company shall not be obligated pursuant to the terms
of this Agreement to indemnify Indemnitee or otherwise act in violation of any undertaking appearing in and required by the rules
and regulations promulgated under the Securities Act of 1933, as amended (the “Act”), or in any registration
statement filed with the SEC under the Act. Indemnitee acknowledges that paragraph (h) of Item 512 of Regulation S-K currently
generally requires the Company to undertake in connection with any registration statement filed under the Act to submit the issue
of the enforceability of Indemnitee’s rights under this Agreement in connection with any liability under the Act on public
policy grounds to a court of appropriate jurisdiction and to be governed by any final adjudication of such issue. Indemnitee specifically
agrees that any such undertaking shall supersede the provisions of this Agreement and to be bound by any such undertaking.

 

11.         Nonexclusivity
and Survival of Rights. The provisions for indemnification and advancement of expenses set forth in this Agreement shall not
be deemed exclusive of any other rights which Indemnitee may at any time be entitled under any provision of applicable law, the
Certificate of Incorporation, Bylaws or other agreements, both as to action in Indemnitee’s official capacity and Indemnitee’s
action as an agent of the Company, in any court in which a proceeding is brought, and Indemnitee’s rights hereunder shall
continue after Indemnitee has ceased acting as an agent of the Company and shall inure to the benefit of the heirs, executors,
administrators and assigns of Indemnitee. The obligations and duties of the Company to Indemnitee under this Agreement shall be
binding on the Company and its successors and assigns until terminated in accordance with its terms. The Company shall require
any successor (whether direct or indirect, by purchase, merger, consolidation or otherwise) to all or substantially all of the
business or assets of the Company, expressly to assume and agree to perform this Agreement in the same manner and to the same extent
that the Company would be required to perform if no such succession had taken place.

 

    	7.

    	 

    

 

No amendment, alteration
or repeal of this Agreement or of any provision hereof shall limit or restrict any right of Indemnitee under this Agreement in
respect of any action taken or omitted by such Indemnitee in his or her corporate status prior to such amendment, alteration or
repeal. To the extent that a change in the DGCL, whether by statute or judicial decision, permits greater indemnification or advancement
of expenses than would be afforded currently under the Certificate of Incorporation, Bylaws and this Agreement, it is the intent
of the parties hereto that Indemnitee shall enjoy by this Agreement the greater benefits so afforded by such change. No right or
remedy herein conferred is intended to be exclusive of any other right or remedy, and every other right and remedy shall be cumulative
and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise.
The assertion or employment of any right or remedy hereunder, or otherwise, by Indemnitee shall not prevent the concurrent assertion
or employment of any other right or remedy by Indemnitee.

 

12.         Subrogation.
In the event of payment under this Agreement, the Company shall be subrogated to the extent of such payment to all of the rights
of recovery of Indemnitee, who, at the request and expense of the Company, shall execute all papers required and shall do everything
that may be reasonably necessary to secure such rights, including the execution of such documents necessary to enable the Company
effectively to bring suit to enforce such rights.

 

13.         Interpretation
of Agreement. It is understood that the parties hereto intend this Agreement to be interpreted and enforced so as to provide
indemnification to Indemnitee to the fullest extent now or hereafter permitted by law.

 

14.         Severability.
If any provision of this Agreement shall be held to be invalid, illegal or unenforceable for any reason whatsoever, (a) the
validity, legality and enforceability of the remaining provisions of the Agreement (including without limitation, all portions
of any paragraphs of this Agreement containing any such provision held to be invalid, illegal or unenforceable, that are not themselves
invalid, illegal or unenforceable) shall not in any way be affected or impaired thereby; and (b) to the fullest extent possible,
the provisions of this Agreement (including, without limitation, all portions of any paragraph of this Agreement containing any
such provision held to be invalid, illegal or unenforceable, that are not themselves invalid, illegal or unenforceable) shall be
construed so as to give effect to the intent manifested by the provision held invalid, illegal or unenforceable and to give effect
to Section 14 hereof.

 

15.         Amendment
and Waiver. No supplement, modification, amendment, or cancellation of this Agreement shall be binding unless executed in writing
by the parties hereto. No waiver of any of the provisions of this Agreement shall be deemed or shall constitute a waiver of any
other provision hereof (whether or not similar) nor shall such waiver constitute a continuing waiver.

 

    	8.

    	 

    

 

 

16.         Notice.
Except as otherwise provided herein, any notice or demand which, by the provisions hereof, is required or which may be given to
or served upon the parties hereto shall be in writing and, if by telegram, telecopy or telex, shall be deemed to have been validly
served, given or delivered when sent, if by overnight delivery, courier or personal delivery, shall be deemed to have been validly
served, given or delivered upon actual delivery and, if mailed, shall be deemed to have been validly served, given or delivered
three (3) business days after deposit in the United States mail, as registered or certified mail, with proper postage prepaid and
addressed to the party or parties to be notified at the addresses set forth on the signature page of this Agreement (or such other
address(es) as a party may designate for itself by like notice). If to the Company, notices and demands shall be delivered to the
attention of the Secretary of the Company.

 

17.         Governing
Law. This Agreement shall be governed exclusively by and construed according to the laws of the State of Delaware, as applied
to contracts between Delaware residents entered into and to be performed entirely within Delaware.

 

18.         Counterparts.
This Agreement may be executed in one or more counterparts, each of which shall for all purposes be deemed to be an original but
all of which together shall constitute but one and the same Agreement. Only one such counterpart need be produced to evidence the
existence of this Agreement.

 

19.         Headings.
The headings of the sections of this Agreement are inserted for convenience only and shall not be deemed to constitute part of
this Agreement or to affect the construction hereof.

 

20.         Entire
Agreement. This Agreement constitutes the entire agreement between the parties with respect to the subject matter hereof and
supersedes all prior agreements, understandings and negotiations, written and oral, between the parties with respect to the subject
matter of this Agreement; provided, however, that this Agreement is a supplement to and in furtherance of the Certificate of Incorporation,
Bylaws, the DGCL and any other applicable law, and shall not be deemed a substitute therefor, and does not diminish or abrogate
any rights of Indemnitee thereunder.
