2.    
       Registration.

 

(a)          Shelf
Registration. No later than sixty (60) days after the Merger Effective Time, the Company shall file a Registration Statement
for a Shelf Registration covering the resale of the Registrable Securities with the SEC for an offering to be made on a continuous
basis pursuant to Rule 415, or if Rule 415 is not available for offers and sales of the Registrable Securities, by such other means

Suspension Period, the Company shall use its commercially reasonable efforts to cause the Shelf Registration Statement to be declared
effective under the Securities Act as promptly as possible after the filing thereof, but in any event (x) no later than the
fifteenth (15th) day following the filing of the Shelf Registration Statement in the event of no “review” by the Commission,
(y) no later than the sixtieth (60th) day following the filing of the Shelf Registration Statement in the event of “limited
review” by the Commission, or (z) in the event of a “review” by the Commission, the one hundred and twentieth
(120th) day following the filing of the Shelf Registration Statement (the number of days in (x), (y) and (z) each being a “Review
Period,” depending on the nature of the Commission’s review, and provided, for any days during the period following
the initial filing of the Shelf Registration Statement and prior to the effectiveness of the Shelf Registration Statement, the
Commission is unable to review or declare effective registration statements filed with the Commission due to a shutdown or partial
shutdown of the U.S. Government (such days, “Tolled Days”), the applicable number of days in such Review Period
shall be extended by the number of Tolled Days), and shall use its commercially reasonable efforts to keep such Shelf Registration
Statement continuously effective under the Securities Act until the date that all Registrable Securities covered by such Registration
Statement are no longer Registrable Securities, including (the period during which the Company shall use its commercially reasonable
efforts to keep the Shelf Registration Statement continuously effective under the Securities Act in accordance with this clause
(i), the “Shelf Period”). The Company shall notify the Holders named in the Shelf Registration Statement via
facsimile or by e-mail of the effectiveness of the Shelf Registration Statement as promptly as practicable, and in any event within
twenty-four (24) hours, after the Company telephonically or otherwise confirms effectiveness with the Commission. The Company shall
file a final Prospectus with the Commission to the extent required by Rule 424. The “Plan of Distribution” section
of such Shelf Registration Statement shall provide for all permitted means of disposition of Registrable Securities, including
firm-commitment underwritten public offerings, agented transactions, sales directly into the market, purchases or sales by brokers
and sales not involving a public offering. Notwithstanding anything to the contrary contained herein, in the event the Commission
informs the Company that all of the Registrable Securities cannot, as a result of the application of Rule 415, be registered for
resale as a secondary offering on a single registration statement, the Company agrees to promptly (A) inform each of the Holders
thereof, (B) use its reasonable efforts to file amendments to the Initial Registration Statement as required by the Commission
and/or (C) withdraw the Initial Registration Statement and file a new Registration Statement (a “New Registration Statement”),
in either case covering the maximum number of Registrable Securities permitted to be registered by the Commission, on Form S-3
or, if the Company is ineligible to register for resale the Registrable Securities on Form S-3, such other form available to register
for resale the Registrable Securities as a secondary offering; provided, however, that prior to filing such amendment
or New Registration Statement, the Company shall be obligated to use its reasonable efforts to advocate with the Commission for
the registration of all of the Registrable Securities. In the event the Company amends the Initial Registration Statement or files
a New Registration Statement, as the case may be, under clauses (B) or (C) above, the Company will use its reasonable efforts to
file with the Commission, as promptly as allowed by the Commission, one or more Registration Statements on Form S-3 or, if the
Company is ineligible to register for resale the Registrable Securities on Form S-3, such other form available to register for
resale those Registrable Securities that were not registered for resale on the Initial Registration Statement, as amended, or the
New Registration Statement (the “Remainder Registration Statements”). Notwithstanding any other provision of
this Agreement, if the Commission limits the number of Registrable Securities permitted to be registered on a particular Registration
Statement (and notwithstanding that the Company used diligent efforts to advocate with the Commission for the registration of all
or a greater number of Registrable Securities), any required cutback of Registrable Securities shall be applied to the Holders
pro rata in accordance with the number of such Registrable Securities sought to be included in such Registration Statement by reference
to the amount of Registrable Securities purchased by such Holder pursuant to the Share Purchase Agreement as set forth opposite
such Holder’s name on Exhibit A thereto (and in the case of a subsequent transfer, the initial Holder’s transferee)
relative to the aggregate amount of all Registrable Securities.

 

    	 	-5-	 

     

    

 

(b)          Suspension
Period. Notwithstanding any other provision of this Section 2, the Company shall have the right, but not the obligation,
to defer the filing of (but not the preparation of), or suspend the use by the Holders of, any Registration Statement for a period
of up to sixty (60) days (unless a longer period is consented to by Holders of a Majority of Included Registrable Securities) (i)
upon issuance by the Commission of a stop order suspending the effectiveness of such Registration Statement with respect to Registrable
Securities or the initiation of proceedings with respect to such Registration Statement under Section 9(d) or 8(e) of the Securities
Act; (ii) if the Company believes in good faith that any such registration or offering (x) should not be undertaken because
it would reasonably be expected to materially interfere with any material corporate development or plan of the Company or (y) would
require the Company (after consultation with external legal counsel), under applicable securities laws and other laws, to make
disclosure of material nonpublic information that would not otherwise be required to be disclosed at that time and the Company
believes in good faith that such disclosures at that time would not be in the Company’s best interests; provided that
this exception (y) shall continue to apply only during the time that such material nonpublic information has not been disclosed
and remains material; (iii) if the Company elects at such time to offer Company Common Stock or other equity securities of
the Company to (x) fund a merger, third-party tender offer or other business combination, acquisition of assets or similar
transaction or (y) meet rating agency and other capital funding requirements; or (iv) if the Company is pursuing a primary
underwritten offering of Company Common Stock pursuant to a registration statement (any such period, a “Suspension Period”);
provided, that in no event shall the Company declare a Suspension Period more than three times in any twelve (12)
month period. The Company shall (i) give prompt written notice to the Holders of its declaration of a Suspension Period and
of the expiration or termination of the relevant Suspension Period and (ii) promptly resume the process of filing or requesting
for effectiveness, or update the suspended Registration Statement, as the case may be, as may be necessary to permit the Holders
to offer and sell their Registrable Securities in accordance with applicable law.

 

(c)          Required
Information. The Company may require each Holder of Registrable Securities as to which any Registration Statement is being
filed or sale is being effected to furnish to the Company such information regarding the intended method of distribution of such
securities and such other information relating to such Holder and its ownership of Registrable Securities as the Company may from
time to time reasonably request in writing (provided that such information shall be used only in connection with such registration)
and the Company may exclude from such registration or sale the Registrable Securities of any such Holder who fails to furnish such
information within a reasonable time after receiving such request. Each Holder agrees to furnish such information to the Company
and to cooperate with the Company as reasonably necessary to enable the Company to comply with the provisions of this Agreement.

 

    	 	-6-	 

     

    

  

(d)          Cessation
of Registration Rights. All registration rights granted under this Section 2 shall continue to be applicable with
respect to any Holder until such Holder no longer holds any Registrable Securities.

 

3.   
        Registration Procedures. The procedures to be followed by the Company
and each participating Holder to register the sale of Registrable Securities pursuant to a Registration Statement in
accordance with this Agreement, and the respective rights and obligations of the Company and such Holders with respect to the
preparation, filing and effectiveness of such Registration Statement, are as follows:

 

(a)          The
Company will (i) prepare and file a Registration Statement with the Commission (within the time period specified in Section 2(a))
which Registration Statement (A) shall be on a form required by this Agreement (or if not so required, selected by the Company)
for which the Company qualifies, (B) shall be available for the sale of the Registrable Securities in accordance with the
intended method or methods of distribution, and (C) shall comply as to form in all material respects with the requirements
of the applicable form and include and/or incorporate by reference all financial statements required by the Commission to be filed
therewith, (ii) use its commercially reasonable efforts to cause such Registration Statement to become effective and remain
effective for the period provided under Section 2(a), (iii) use its commercially reasonable efforts to prevent
the occurrence of any event that would cause a Registration Statement to contain a material misstatement or omission or to be not
effective and usable for resale of the Registrable Securities registered pursuant thereto (during the period that such Registration
Statement is required to be effective as provided under Section 2(a)), and (iv) cause each Registration Statement
and the related Prospectus and any amendment or supplement thereto, as of the effective date of such Registration Statement, amendment
or supplement, (x) to comply in all material respects with any requirements of the Securities Act and the rules and regulations
of the Commission and (y) not to contain any 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 not misleading (provided, however, the Company shall have no liability
for any information furnished in writing by or on behalf of a Holder to the Company specifically for inclusion in (including by
incorporation by reference) any such Registration Statement that has not been corrected in a subsequent writing to the Company
prior to the filing or other disclosure of such information). The Company will, (1) at least three (3) Business Days
prior to the anticipated filing of a Registration Statement or any related Prospectus or any amendment or supplement thereto (including
any documents incorporated by reference therein), furnish to such Holders and such Holders’ counsel copies of all such documents
proposed to be filed and make such representatives of the Company as shall be reasonably requested by the Holders available for
discussion of such documents, (2) use its commercially reasonable efforts to address in each such document prior to being
so filed with the Commission such comments as each such Holder or its counsel reasonably shall propose within two (2) Business
Days of receipt of such copies by the Holders and (3) not file any Registration Statement or any related Prospectus or any
amendment or supplement thereto containing information regarding a participating Holder to which such participating Holder objects,
unless such information is required by applicable law or regulation.

Company will as promptly as reasonably practicable (i) prepare and file with the Commission such amendments, including post-effective
amendments, and supplements to each Registration Statement and the Prospectus used in connection therewith as (A) may be reasonably
requested by any Holder of Registrable Securities covered by such Registration Statement necessary to permit such Holder to sell
in accordance with its intended method of distribution or (B) may be necessary under applicable law to keep such Registration
Statement continuously effective with respect to the disposition of all Registrable Securities covered thereby for the period provided
under Section 2(a) in accordance with the intended method of distribution and, subject to the limitations contained
in this Agreement, prepare and file with the Commission such additional Registration Statements in order to register for resale

or supplemented by any required prospectus supplement, and as so supplemented or amended, to be filed pursuant to Rule 424, (iii) respond
to any comments received from the Commission with respect to each Registration Statement or Prospectus or any amendment thereto,
and (iv) as promptly as reasonably practicable, provide such Holders true and complete copies of all correspondence from and
to the Commission relating to such Registration Statement or Prospectus other than any comments that the Company determines in
good faith would result in the disclosure to such Holders of material non-public information concerning the Company that is not
already in the possession of such Holder.

 

(c)          The
Company will comply in all material respects with the provisions of the Securities Act and the Exchange Act (including Regulation

of such Holder); and (C) with respect to each Registration Statement or any post-effective amendment thereto, when the same
has been declared effective; (ii) of any request by the Commission or any other federal or state governmental or regulatory
authority for amendments or supplements to a Registration Statement or Prospectus or for additional information (whether before
or after the effective date of the Registration Statement) or any other correspondence with the Commission or any such authority
relating to, or which may affect, the Registration Statement; (iii) of the issuance by the Commission or any other governmental
or regulatory authority of any stop order, injunction or other order or requirement suspending the effectiveness of a Registration
Statement covering any or all of the Registrable Securities or preventing or suspending the use of any Prospectus or the initiation
or threatening of any Proceedings for such purpose; (iv) of the receipt by the Company of any notification with respect to
the suspension of the qualification or exemption from qualification of any of the Registrable Securities for sale in any jurisdiction,
or the initiation or threatening of any Proceeding for such purpose; or (v) of the occurrence of any event that makes any
statement made in such Registration Statement or Prospectus or any document incorporated or deemed to be incorporated therein by
reference untrue in any material respect or if, as a result of such event or the passage of time, such Registration Statement,
Prospectus or other documents requires revisions so that, in the case of such Registration Statement or the Prospectus, as the
case may be, it will not contain any untrue statement of a material fact or omit to state any material fact required to be stated
therein or necessary to make the statements therein (in the case of the Prospectus, in light of the circumstances under which they
were made) not misleading, or if, for any other reason, it shall be necessary during such time period to amend or supplement such
Registration Statement or Prospectus in order to comply with the Securities Act, which shall correct such misstatement or omission
or effect such compliance.

 

    	 	-8-	 

     

    

 

(e)          The
Company will use its commercially reasonable efforts to avoid the issuance of, or, if issued, obtain the withdrawal of (i) any
stop order or other order suspending the effectiveness of a Registration Statement, or preventing or suspending the use of any
Prospectus, or (ii) any suspension of the qualification (or exemption from qualification) of any of the Registrable Securities
for sale in any jurisdiction, as soon as reasonable practicable, or if any such order or suspension is made effective during any
Suspension Period, as soon as reasonable practicable after the Suspension Period is over.

 

(f)          During
the Shelf Period, the Company will furnish to each selling Holder and its counsel upon their request, without charge, at least
one conformed copy of each Registration Statement and each amendment thereto and all exhibits to the extent requested by such selling
Holder or counsel (including those incorporated by reference) promptly after the filing of such documents with the Commission.

 

(g)          The
Company will promptly deliver to each selling Holder and its counsel as many copies of each Prospectus or Prospectuses (including
each form of prospectus) and each amendment or supplement thereto as such selling Holder or counsel may reasonably request in order
to facilitate the disposition of the Registrable Securities by such selling Holder. The Company hereby consents to the use of such
Prospectus and each amendment or supplement thereto by each of the selling Holders in connection with the offering and sale of
the Registrable Securities covered by such Prospectus and any amendment or supplement thereto, so long as the same are used in
compliance with the Securities Act and all other applicable laws and regulations.

 

(h)          To
the extent that the Company has certificated shares of Company Common Stock, the Company will cooperate with each selling Holder
to facilitate the timely preparation and delivery of certificates representing Registrable Securities to be delivered to a transferee
pursuant to a Registration Statement, which certificates shall be free of all restrictive legends indicating that the Registrable
Securities are unregistered or unqualified for resale under the Securities Act, Exchange Act or other applicable securities laws,
and to enable such Registrable Securities to be in such denominations and registered in such names as each selling Holder may request
in writing. In connection therewith, if required by the Company’s transfer agent, the Company will promptly, after the effective
date of the Registration Statement, cause an opinion of counsel as to the effectiveness of the Registration Statement to be delivered
to and maintained with such transfer agent, together with any other authorizations, certificates and directions required by the
transfer agent which authorize and direct the transfer agent to issue such Registrable Securities without any such legend upon
sale by the Holder of such Registrable Securities pursuant to the Registration Statement.

 

(i)          Upon
the occurrence of any event contemplated by Section 3(d)(v), as promptly as reasonably practicable, the Company will
prepare a supplement or amendment, including a post-effective amendment, if required by applicable law, to the affected Registration
Statement or a supplement to the related Prospectus or any document incorporated or deemed to be incorporated therein by reference,
and file any other required document so that, as thereafter delivered, no Registration Statement nor any Prospectus will contain
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 the case of a Prospectus, in light of the circumstances under which they were made) not misleading, such
that each selling Holder can resume disposition of such Registrable Securities covered by such Registration Statement or Prospectus.

 

(j)          The
Company will use its commercially reasonable efforts to comply with all applicable rules and regulations of the Commission, the
Trading Market and FINRA.

 

    	 	-9-	 

     

    

 

(k)          Each
Holder agrees by its acquisition of Registrable Securities that, upon receipt of a notice from the Company of the occurrence of
any event of the kind described in clauses (ii) through (v) of Section 3(d) or the occurrence of a Suspension
Period, such Holder will forthwith discontinue disposition of such Registrable Securities under the applicable Registration Statement
until such Holder’s receipt of the copies of the supplemental Prospectus or amended Registration Statement or until it is
advised in writing by the Company that the use of the applicable Prospectus may be resumed, and, in either case, has received copies
of any additional or supplemental filings that are incorporated or deemed to be incorporated by reference in such Prospectus or
Registration Statement.  In the event the Company shall give any such notice, the period during which the applicable Registration
Statement is required to be maintained effective 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 each seller of Registrable Securities covered by such Registration
Statement either receives the copies of the supplemented Prospectus or amended Registration Statement or is advised in writing
by the Company that the use of the Prospectus may be resumed.

 

(l)          Each
Holder hereby covenants with the Company (i) not to make any sale of any Registrable Securities without effectively causing the
prospectus delivery requirements under the Securities Act to be satisfied, and (ii) if such Registrable Securities are to be sold
by any method or in any transaction other than on a national securities exchange or in the over-the-counter market, in privately
negotiated transactions, or in a combination of such methods, to notify the Company at least five Business Days prior to the date
on which the Holder first offers to sell any such Registrable Securities.

 

4.      
     Registration Expenses. All Registration Expenses incurred in connection with any
registration, qualification, exemption or compliance pursuant to Section 2.1(a) hereof shall be borne by the Company. All
Selling Expenses relating to the sale of securities registered by or on behalf of Holders shall be borne by such Holders pro
rata on the basis of the number of securities so registered.

 

5.     
      Indemnification.

 

(a)          The
Company shall indemnify and hold harmless each Holder, its partners, stockholders, equity holders, general partners, managers,
members, and Affiliates and each of their respective officers and directors and any Person who controls any such Holder (within
the meaning of the Securities Act or the Exchange Act) and any employee or Representative thereof (collectively, each, an “Company
Indemnified Person” and collectively, “Company Indemnified Persons”), to the fullest extent permitted
by law, from and against any and all losses, claims, damages, liabilities, joint or several, costs (including reasonable costs
of preparation and reasonable attorneys’, accountants’ and experts’ fees) and expenses, judgments, fines, penalties,
interest, settlements or other amounts arising from any and all claims, demands, actions, suits or proceedings, whether civil,
criminal, administrative or investigative, in which any Company Indemnified Person may be involved, or is threatened to be involved,
as a party or otherwise, under the Securities Act, the Exchange Act or otherwise (collectively, “Losses”), as
incurred, arising out of, based upon, resulting from or relating to (i) any untrue or alleged untrue statement of a material
fact contained in any Registration Statement under which any Registrable Securities were registered, Prospectus (including in any
preliminary prospectus (if used prior to the effective date of such Registration Statement)), or in any summary or final prospectus
or in any amendment or supplement thereto or in any documents incorporated or deemed incorporated by reference in any of the foregoing
or (ii) any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make
the statements made therein (in the case of the Prospectus, in light of the circumstances under which they were made) not misleading,
or (iii) any violation or alleged violation by the Company or any of its Subsidiaries of the Securities Act, the Exchange Act,
any state securities law or any rule or regulation promulgated under the Securities Act, the Exchange Act or any federal, state,
foreign or common law rule or regulation in connection with such Registration Statement, disclosure document or related document
or report or any offering covered by such Registration Statement, and the Company shall reimburse such Company Indemnified Person
for any reasonable legal or other expenses reasonably incurred by it in connection with investigating or defending any such loss,
claim, damage, liability, demand, action, suit or proceeding; provided, however, that the Company shall not
be liable to any Company Indemnified Person to the extent that any such Losses arise out of, are based upon or results from an
untrue or alleged untrue statement or omission or alleged omission made in such Registration Statement, such preliminary, summary
or final prospectus or such amendment or supplement, or other disclosure document, in reliance upon and in conformity with written
information furnished to the Company by or on behalf of such Company Indemnified Person specifically for use therein.

 

    	 	-10-	 

     

    

 

(b)          In
connection with any Registration Statement filed by the Company pursuant to Section 2(a) hereof in which a Holder has
registered for sale its Registrable Securities, each such selling Holder agrees (severally and not jointly) to indemnify and hold
harmless, to the fullest extent permitted by law, the Company, its directors and officers, employees, agents and each Person who
controls the Company (within the meaning of the Securities Act or the Exchange Act) and any other Holder selling securities under
such Registration Statement, its partners, stockholders, equity holders, general partners, managers, members, and Affiliates and
each of their respective officers and directors and any Person who controls such other Holder (within the meaning of the Securities
Act or the Exchange Act) and any employee or Representative thereof (collectively, “Holder Indemnified Persons”,
and together with the Company Indemnified Persons, each an “Indemnified Person”, and collectively, the “Indemnified
Persons”) from and against any Losses resulting from (i) any untrue or alleged untrue statement of a material fact
contained in any Registration Statement under which such Registrable Securities were registered or sold under the Securities Act,
Prospectus (including in any preliminary prospectus (if used prior to the effective date of such Registration Statement)), or in
any summary or final prospectus or in any amendment or supplement thereto or in any documents incorporated by reference in any
of the foregoing, (ii) any omission or alleged omission to state therein a material fact required to be stated therein or
necessary to make the statements therein (in the case of the Prospectus, in light of the circumstances under which they were made)
not misleading, or (iii) any violation or alleged violation by such Holder of any federal, state or common law rule or regulation
relating to action or inaction in connection with any information provided by such Holder in such registration, disclosure document
or related document or report in the case of clauses (i) and (ii) to the extent, but only to the extent, that such untrue statement
or omission occurs in reliance upon and in conformity with any information furnished in writing by or on behalf of such Holder
Indemnified Person specifically for inclusion in such registration, disclosure document or related document or report and has not
been corrected in a subsequent writing prior to the sale of the Registrable Securities thereunder, and the Holder will reimburse
the Company for any legal or other expenses reasonably incurred by it in connection with investigating or defending such Losses.
In no event shall the liability of any selling Holder hereunder be greater in amount than the dollar amount of the net proceeds
received by such Holder under the sale of Registrable Securities giving rise to such indemnification obligation.

 

(c)          Any
Indemnified Person under paragraph (a) or (b) of this Section 5 shall (i) give prompt written notice to the indemnifying
person under paragraph (a) or (b) of this Section 5 of any claim with respect to which it seeks indemnification (provided
that any delay or failure to so notify the indemnifying person shall not relieve the indemnifying party of its obligations hereunder
except to the extent, if at all, that the indemnifying person’s ability to defend such claim (through the forfeiture of substantive
rights or defenses) is actually and materially prejudiced by reason of such delay or failure) and (ii) permit such indemnifying
person to assume the defense of such claim with counsel reasonably satisfactory to the Indemnified Person; provided, however,
that any Indemnified Person shall have the right to select and employ separate counsel and to participate in the defense of such
claim, but the fees and expenses of such counsel shall be at the expense of such Indemnified Person unless (A) the indemnifying
person has agreed in writing to pay such fees or expenses, (B) the Indemnified Person has reasonably concluded (based upon
advice of its counsel) that there may be legal defenses available to it or other Indemnified Persons that are different from or
in addition to those available to the indemnifying person, or (C) in the reasonable judgment of any such Indemnified Person
(based upon advice of its counsel) a conflict of interest may exist between such Indemnified Person and the indemnifying person
with respect to such claims (in which case, if the Indemnified Person notifies the indemnifying person in writing that such Indemnified
Person elects to employ separate counsel at the expense of the indemnifying person, the indemnifying person shall not have the
right to assume the defense of such claim on behalf of such Indemnified Person). If any action is settled or if there be a final
judgment for the plaintiff, the indemnifying person agrees to indemnify each Indemnified Person from and against any loss or liability
by reason of such settlement or judgment. No action may be settled without the written consent of the Indemnified Person (which
consent shall not be unreasonably withheld, delayed or conditioned), provided that the consent of the Indemnified Person
shall not be required if (A) such settlement includes an unconditional release of such Indemnified Person in form and substance
satisfactory to such Indemnified Person from all liability on the claims that are the subject matter of such settlement; (B) such
settlement provides for the payment by the indemnifying person of money as the sole relief for such action and (C) such settlement
does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of any Indemnified
Person. It is understood that the indemnifying person or persons shall not, except as specifically set forth in this Section 5(c),
in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the reasonable fees, disbursements
or other charges of more than one separate firm (in addition to any local counsel that is required to effectively defend against
any such proceeding) for all Indemnified Persons and that all such fees and expenses shall be paid or reimbursed promptly.

 

    	 	-11-	 

     

    

 

(d)          If
the indemnification provided for in this Section 5 is held by a court of a competent jurisdiction to be unavailable
to an Indemnified Person with respect to any loss, damage, claim or liability, the indemnifying party, in lieu of indemnifying
such Indemnified Person thereunder, shall to the extent permitted by law, contribute to the amount paid or payable by such Indemnified
Person as a result of such loss, damage, claim or liability in such proportion as is appropriate to reflect the relative fault
of the indemnifying party on the one hand and of the Indemnified Person on the other in connection with the actions that resulted
in such loss, claim, damage or liability, as well as any other relevant equitable considerations. The relative fault of the indemnifying
person and of the Indemnified Person shall be determined by a court of law 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 person or Indemnified Person and the parties’ relative intent, knowledge, access to information and opportunity
to correct or prevent such statement or omission. The Parties agree that it would not be just and equitable if contribution pursuant
to this Section 5(d) 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 sentences. Notwithstanding the provisions of this Section 5(d),
no selling Holder shall be required to contribute any amount in excess of the net proceeds (after deducting the underwriters’
discounts and commissions) received by such selling Holder in the offering. 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. Each selling Holder’s obligation to contribute pursuant to this Section 5(d)
is several in the proportion that the net proceeds of the offering received by such selling Holder bears to the total net proceeds
of the offering received by all such selling Holders and not joint.

 

(e)          The
remedies provided for in this Section 5 are not exclusive and shall not limit any rights or remedies which may otherwise
be available to any Indemnified Person at law or in equity. The obligations of the Company and Holders under this Section 5
shall survive completion of any offering of Registrable Securities pursuant to a Registration Statement and the termination of
this Agreement.

 

6.      
     Facilitation of Sales Pursuant to Rule 144. The Company shall use its commercially
reasonable efforts to timely file the reports required to be filed by it under the Exchange Act or the Securities Act and the
rules adopted by the Commission thereunder (including the reports under Sections 13 and 15(d) of the Exchange Act
referred to in subparagraph (c)(1) of Rule 144), all to the extent required from time to time to enable the Holders to
sell Registrable Securities without registration under the Securities Act within the limitations of the exemption provided by
Rule 144. Upon the written request of any Holder in connection with that Holder’s sale pursuant to Rule 144,
the Company shall deliver to such Holder a written statement as to whether it has complied with such requirements.

 

    	 	-12-	 

     

    

 

7.     
      Miscellaneous.

 

(a)          Remedies.
In the event of a breach by the Company or a Holder of any of its obligations under this Agreement, any Party, in addition to being
entitled to exercise all rights granted by law and under this Agreement, including recovery of damages, will be entitled to specific
performance of its rights under this Agreement. The Parties agree that monetary damages would not provide adequate compensation
for any losses incurred by reason of a breach by it of any of the provisions of this Agreement and further agrees that, in the
event of any action for specific performance in respect of such breach, it shall waive the defense that a remedy at law would be
adequate and shall waive any requirement for the posting of a bond. No failure or delay by any Person in exercising any right,
power or privilege hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other
or further exercise thereof or the exercise of any other right, power or privilege. The rights and remedies herein provided shall
be cumulative and not exclusive of any rights or remedies provided by law.

 

(b)          Amendment;
Modification; Waivers. This Agreement may be amended or waived if, and only if, such amendment or waiver is in writing and
signed by the Company and holders of a majority of the Registrable Securities then owned by the Holders and such amendment or waiver
treats all holders of capital stock equally in all respects, which writing shall specifically reference this Agreement, specify
the provision(s) hereof that it is intended to amend or waive and further specify that it is intended to amend or waive such provision(s).
No amendment or waiver is permitted if such amendment or waiver would adversely affect a Holder relative to the other Holders without
such Holder’s written consent.

 

(c)          Notices.
All notices and other communications hereunder shall be in writing and shall be deemed duly given (a) upon delivery, if served
by personal delivery upon the Person for whom it is intended, (b) on the third Business Day after the date mailed if delivered
by registered or certified mail, return receipt requested, postage prepaid, (c) on the following Business Day if delivered
by a nationally-recognized, overnight courier or (d) when delivered or, if sent after the Close of Business, on the following
Business Day if sent by facsimile transmission or email with electronic confirmation, in each case, to the address set forth on
the signature page of this Agreement or to such other address as may be designated in writing, in the same manner, by such Person.
If to any other Person who is then a Holder, to the address of such Holder as it appears on the signature pages hereto or such
other address as may be designated in writing hereafter by such Person.

 

(d)          Governing
Law; Jurisdiction; Waiver of Jury Trial. This Agreement shall be governed by, and construed in accordance with, the laws of
the State of Washington, regardless of the laws that might otherwise govern under applicable principles of conflicts of laws. In
any action or proceeding between any of the parties arising out of or relating to this Agreement, each of the parties: (a) irrevocably
and unconditionally consents and submits to the exclusive jurisdiction and venue of the King County West Division of the State
of Washington or, to the extent such court does not have subject matter jurisdiction, the United States District Court for the
District of Washington or, to the extent that neither of the foregoing courts has jurisdiction, the Superior Court of the State
of Washington; (b) agrees that all claims in respect of such action or proceeding shall be heard and determined exclusively in
accordance with clause (a) of this Section 7(d); (c) waives any objection to laying venue in any such action or proceeding
in such courts; (d) waives any objection that such courts are an inconvenient forum or do not have jurisdiction over any party
hereto; and (e) irrevocably and unconditionally waives the right to trial by jury.

 

    	 	-13-	 

     

    

 

(e)          Successors
and Assigns. This Agreement shall be binding upon and inure to the benefit of the Parties hereto and their respective heirs,
executors, administrators, successors, legal representatives, and Approved Transferees.

 

(f)          Waiver
of Venue. The Parties irrevocably and unconditionally waive, to the fullest extent permitted by applicable law, (i) any
objection that they may now or hereafter have to the laying of venue of any action or proceeding arising out of or relating to
this Agreement in any court referred to in Section 7(d) and (ii) the defense of an inconvenient forum to the maintenance
of such action or proceeding in any such court.

 

(g)          Waiver
of Trial by Jury. EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT OR IS LIKELY
TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE EACH SUCH PERSON HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT
SUCH PERSON MAY HAVE TO A TRIAL BY JURY WITH RESPECT TO ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS
AGREEMENT. EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT (i) NO REPRESENTATIVE, AGENT OR ATTORNEY OF THE OTHER PERSON HAS REPRESENTED,
EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PERSON WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER, (ii) SUCH
PERSON UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER, (iii) SUCH PERSON MAKES THIS WAIVER VOLUNTARILY, AND
(iv) SUCH PERSON HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT AND EACH ANCILLARY AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL
WAIVERS AND CERTIFICATIONS IN THIS SECTION.

 

(h)          Severability.
The provisions of this Agreement shall be deemed severable and the invalidity or unenforceability of any provision hereof shall
not affect the validity or enforceability of any other provision. Whenever possible, each provision or portion of any provision
of this Agreement shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of
this Agreement, or the application thereof to any Person or any circumstance, is invalid or unenforceable, (i) a suitable
and equitable provision shall be substituted therefor to carry out, so far as may be valid and enforceable, the intent and purpose
of such invalid or unenforceable provision and (ii) the remainder of this Agreement and the application of such provision
to other Persons or circumstances shall not be affected by such invalidity or unenforceability, nor shall such invalidity or unenforceability
affect the validity or enforceability of such provision, or the application thereof, in any other jurisdiction; provided, that,
if any one or more of the provisions contained in this Agreement shall be determined to be excessively broad as to activity, subject,
duration or geographic scope, it shall be reformed by limiting and reducing it to the minimum extent necessary, so as to be enforceable
under applicable law.

 

(i)          Business
Days. If the last or appointed day for the taking of any action or the expiration of any right required or granted herein shall
be a day other than a Business Day, then such action may be taken or such right may be exercised on the next succeeding Business
Day.

 

(j)          Entire
Agreement. This Agreement constitutes the entire agreement among the Parties with respect to the subject matter hereof and
supersedes all prior contracts or agreements with respect to the subject matter hereof and supersedes any and all prior or contemporaneous
discussions, agreements and understandings, whether oral or written, that may have been made or entered into by or among any of
the Parties or any of their respective Affiliates relating to the transactions contemplated hereby.

 

    	 	-14-	 

     

    

 

(k)         Execution
of Agreement. This Agreement may be executed and delivered (by facsimile, by electronic mail in Adobe Portable Document Format
(.pdf) or otherwise) in any number of counterparts, each of which, when executed and delivered, shall be deemed an original, and
all of which together shall constitute the same agreement.

 

(l)          Determination
of Ownership. In determining ownership of Company Common Stock hereunder for any purpose, the Company may rely solely on the
records of the transfer agent for the Company Common Stock from time to time, or, if no such transfer agent exists, the Company’s
stock ledger.

 

(m)        No
Recourse. Notwithstanding anything that may be expressed or implied in this Agreement, and notwithstanding the fact that certain
of the Holders may be partnerships or limited liability companies, each Holder covenants, agrees and acknowledges that no recourse
under this Agreement or any documents or instruments delivered in connection with this Agreement shall be had against any of the
Company’s or the Holder’s former, current or future direct or indirect equity holders, controlling persons, stockholders,
directors, officers, employees, agents, Affiliates, members, financing sources, managers, general or limited partners or assignees
(each, a “Related Person” and collectively, the “Related Persons”), in each case other than
the Company, the Holders or any of their permitted assigns under this Agreement, whether by the enforcement of any assessment or
by any legal or equitable proceeding, or by virtue of any applicable law, it being expressly agreed and acknowledged that no personal
liability whatsoever shall attach to, be imposed on or otherwise be incurred by any of the Related Persons, as such, for any obligation
or liability of the Company or the Holders under this Agreement or any documents or instruments delivered in connection herewith
for any claim based on, in respect of or by reason of such obligations or liabilities or their creation; provided, however, nothing
in this Section 7(m) shall relieve or otherwise limit the liability of the Company or any Holder, as such, for any
breach or violation of its obligations under this Agreement or such agreements, documents or instruments.

 

(n)         Third-Party
Beneficiaries. Nothing in this Agreement, express or implied, is intended to confer upon any Person other than a Party and
their respective successors and permitted assigns any rights, benefits or remedies of any nature whatsoever.

 

(o)         Headings;
Section References; Signatories. All heading references contained in this Agreement are for convenience purposes only
