A.
Upon the terms and subject to the conditions of the Purchase Agreement, (i) the Company has agreed to issue to the Investor, and the

and (ii) the Company has agreed to issue to the Investor such number of shares of Common Stock as consideration for its commitment to

B.
To induce the Investor to enter into the Purchase Agreement, the Company has agreed to provide certain registration rights under the

e.
“Registration Statement” means one or more registration statements of the Company covering only the sale of the Registrable
Securities.

 

2.
REGISTRATION.

 

a.
Mandatory Registration. The Company shall, within twenty (20) Business Days after the date hereof, file with the SEC an initial
Registration Statement covering the maximum number of Registrable Securities, which shall include all of the Commitment Shares and such
number of additional Registrable Securities as shall be permitted to be included thereon in accordance with applicable SEC rules, regulations
and interpretations so as to permit the resale of such Registrable Securities by the Investor under Rule 415 under the Securities Act
at then prevailing market prices (and not fixed prices), as mutually determined by both the Company and the Investor in consultation
with their respective legal counsel. The initial Registration Statement shall register only the Registrable Securities. The Investor
and its counsel shall have a reasonable opportunity to review and comment upon such Registration Statement and any amendment or supplement
to such Registration Statement and any related prospectus prior to its filing with the SEC, and the Company shall give due consideration
to all such comments. The Investor shall furnish all information reasonably requested by the Company for inclusion therein. The Company
shall use its reasonable best efforts to have the Registration Statement and any amendment declared effective by the SEC at the earliest
possible date. The Company shall use reasonable best efforts to keep the Registration Statement effective pursuant to Rule 415 promulgated
under the Securities Act and available for the resale by the Investor of all of the Registrable Securities covered thereby at all times
until the date on which the Investor shall have resold all the Registrable Securities covered thereby and no Available Amount remains
under the Purchase Agreement (the “Registration Period”). The Registration Statement (including any amendments or
supplements thereto and prospectuses contained therein) shall not 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, in light of the circumstances in which they
were made, not misleading.

 

b.
Rule 424 Prospectus. The Company shall, as required by applicable securities regulations, from time to time file with the SEC,
pursuant to Rule 424 promulgated under the Securities Act, the prospectus and prospectus supplements, if any, to be used in connection
with sales of the Registrable Securities under the Registration Statement. The Investor and its counsel shall have a reasonable opportunity
to review and comment upon such prospectus prior to its filing with the SEC, and the Company shall give due consideration to all such
comments. The Investor shall use its reasonable best efforts to comment upon such prospectus within one (1) Business Day from the date
the Investor receives the final pre-filing version of such prospectus.

 

c.
Sufficient Number of Shares Registered. In the event the number of shares available under the Registration Statement is insufficient
to cover all of the Registrable Securities, the Company shall amend the Registration Statement or file a new Registration Statement (a
“New Registration Statement”), so as to cover all of such Registrable Securities (subject to the limitations set forth
in Section 2(a)) as soon as practicable, but in any event not later than ten (10) Business Days after the necessity therefor arises,
subject to any limits that may be imposed by the SEC pursuant to Rule 415 under the Securities Act. The Company shall use its reasonable
best efforts to cause such amendment and/or New Registration Statement to become effective as soon as practicable following the filing
thereof.

 

    2

     

    

 

d.
Offering. If the staff of the SEC (the “Staff”) or the SEC seeks to characterize any offering pursuant to a
Registration Statement filed pursuant to this Agreement as constituting an offering of securities that does not permit such Registration
Statement to become effective and be used for resales by the Investor under Rule 415 at then-prevailing market prices (and not fixed
prices), or if after the filing of the initial Registration Statement with the SEC pursuant to Section 2(a), the Company is otherwise
required by the Staff or the SEC to reduce the number of Registrable Securities included in such initial Registration Statement, then
the Company shall reduce the number of Registrable Securities to be included in such initial Registration Statement (after consulting
with the Investor and its legal counsel as to the specific Registrable Securities to be removed therefrom) until such time as the Staff
and the SEC shall so permit such Registration Statement to become effective and be used as aforesaid. In the event of any reduction in
Registrable Securities pursuant to this paragraph, the Company shall file one or more New Registration Statements in accordance with
Section 2(c) until such time as all Registrable Securities have been included in Registration Statements that have been declared effective
and the prospectus contained therein is available for use by the Investor. Notwithstanding any provision herein or in the Purchase Agreement
to the contrary, the Company’s obligations to register Registrable Securities (and any related conditions to the Investor’s
obligations) shall be qualified as necessary to comport with any requirement of the SEC or the Staff as addressed in this Section 2(d).

 

3.
RELATED OBLIGATIONS.

 

With
respect to the Registration Statement and whenever any Registrable Securities are to be registered pursuant to Section 2 including on
any New Registration Statement, the Company shall use its reasonable best efforts to effect the registration of the Registrable Securities
in accordance with the intended method of disposition thereof and, pursuant thereto, the Company shall have the following obligations:

 

a.
The Company shall prepare and file with the SEC such amendments (including post-effective amendments) and supplements to any registration
statement and the prospectus used in connection with such registration statement, which prospectus is to be filed pursuant to Rule 424
promulgated under the Securities Act, as may be necessary to keep the Registration Statement or any New Registration Statement effective
at all times during the Registration Period, and, during such period, comply with the provisions of the Securities Act with respect to
the disposition of all Registrable Securities of the Company covered by the Registration Statement or any New Registration Statement
until such time as all of such Registrable Securities shall have been disposed of in accordance with the intended methods of disposition
by the seller or sellers thereof as set forth in such Registration Statement.

 

b.
The Company shall permit the Investor to review and comment upon the Registration Statement or any New Registration Statement and all
amendments and supplements thereto at least two (2) Business Days prior to their filing with the SEC, and not file any such document
in a form to which Investor reasonably objects. The Investor shall use its reasonable best efforts to comment upon the Registration Statement
or any New Registration Statement and any amendments or supplements thereto within two (2) Business Days from the date the Investor receives
the final version thereof. The Company shall furnish to the Investor, without charge any correspondence from the SEC or the staff of
the SEC to the Company or its representatives relating to the Registration Statement or any New Registration Statement.

 

c.
Upon request of the Investor, the Company shall furnish to the Investor, (i) promptly after the same is prepared and filed with the SEC,
at least one copy of such registration statement and any amendment(s) thereto, including financial statements and schedules, all documents
incorporated therein by reference and all exhibits, (ii) upon the effectiveness of any registration statement, a copy of the prospectus
included in such registration statement and all amendments and supplements thereto (or such other number of copies as the Investor may
reasonably request) and (iii) such other documents, including copies of any preliminary or final prospectus, as the Investor may reasonably
request from time to time in order to facilitate the disposition of the Registrable Securities owned by the Investor. For the avoidance
of doubt, any filing available to the Investor via the SEC’s live EDGAR system shall be deemed “furnished to the Investor”
hereunder.

 

    3

     

    

 

d.
The Company shall use reasonable best efforts to (i) register and qualify the Registrable Securities covered by a registration statement
under such other securities or “blue sky” laws of such jurisdictions in the United States as the Investor reasonably requests,
(ii) prepare and file in those jurisdictions, such amendments (including post-effective amendments) and supplements to such registrations
and qualifications as may be necessary to maintain the effectiveness thereof during the Registration Period, (iii) take such other actions
as may be necessary to maintain such registrations and qualifications in effect at all times during the Registration Period, and (iv)
take all other actions reasonably necessary or advisable to qualify the Registrable Securities for sale in such jurisdictions; provided,
however, that the Company shall not be required in connection therewith or as a condition thereto to (x) qualify to do business in any
jurisdiction where it would not otherwise be required to qualify but for this Section 3(d), (y) subject itself to general taxation in
any such jurisdiction, or (z) file a general consent to service of process in any such jurisdiction. The Company shall promptly notify
the Investor who holds Registrable Securities of the receipt by the Company of any notification with respect to the suspension of the
registration or qualification of any of the Registrable Securities for sale under the securities or “blue sky” laws of any
jurisdiction in the United States or its receipt of actual notice of the initiation or threatening of any proceeding for such purpose.

 

e.
As promptly as practicable after becoming aware of such event or facts, the Company shall notify the Investor in writing of the happening
of any event or existence of such facts as a result of which the prospectus included in any registration statement, as then in effect,
includes an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make
the statements therein, in light of the circumstances under which they were made, not misleading, and promptly prepare a supplement or
amendment to such registration statement to correct such untrue statement or omission, and deliver a copy of such supplement or amendment
to the Investor (or such other number of copies as the Investor may reasonably request). The Company shall also promptly notify the Investor
in writing (i) when a prospectus or any prospectus supplement or post-effective amendment has been filed, and when a registration statement
or any post-effective amendment has become effective (notification of such effectiveness shall be delivered to the Investor by email
or facsimile on the same day of such effectiveness and by overnight mail), (ii) of any request by the SEC for amendments or supplements
to any registration statement or related prospectus or related information, and (iii) of the Company’s reasonable determination
that a post-effective amendment to a registration statement would be appropriate.

 

f.
The Company shall use its reasonable best efforts to prevent the issuance of any stop order or other suspension of effectiveness of any
registration statement, or the suspension of the qualification of any Registrable Securities for sale in any jurisdiction and, if such
an order or suspension is issued, to obtain the withdrawal of such order or suspension at the earliest possible moment and to notify
the Investor of the issuance of such order and the resolution thereof or its receipt of actual notice of the initiation or threat of
any proceeding for such purpose.

 

g.
The Company shall (i) cause all the Registrable Securities to be listed on each securities exchange on which securities of the same class
or series issued by the Company are then listed, if any, if the listing of such Registrable Securities is then permitted under the rules
of such exchange, or (ii) secure designation and quotation of all the Registrable Securities on the Principal Market. The Company shall
pay all fees and expenses in connection with satisfying its obligation under this Section.

 

    4

     

    

 

h.
The Company shall cooperate with the Investor to facilitate the timely preparation and delivery of certificates (not bearing any restrictive
legend) representing the Registrable Securities to be offered pursuant to any registration statement and enable such certificates to
be in such denominations or amounts as the Investor may reasonably request and registered in such names as the Investor may request.

 

i.
The Company shall at all times provide a transfer agent and registrar with respect to its Common Stock.

 

j.
If reasonably requested by the Investor, the Company shall (i) as soon as practicable after receipt of written notice from the Investor
incorporate in a prospectus supplement or post-effective amendment such information as the Investor believes should be included therein
relating to the sale and distribution of Registrable Securities, including, without limitation, information with respect to the number
of Registrable Securities being sold, the purchase price being paid therefor and any other terms of the offering of the Registrable Securities;
(ii) make all required filings of such prospectus supplement or post-effective amendment as soon as practicable upon notification of
the matters to be incorporated in such prospectus supplement or post-effective amendment; and (iii) supplement or make amendments to
any Registration Statement or New Registration Statement.

 

k.
The Company shall use its reasonable best efforts to cause the Registrable Securities covered by any registration statement to be registered
with or approved by such other governmental agencies or authorities as may be necessary to consummate the disposition of such Registrable
Securities.

 

l.
Within one (1) Business Day after any registration statement which includes the Registrable Securities is declared effective by the SEC,
the Company shall deliver, and shall cause legal counsel for the Company to deliver, to the transfer agent for such Registrable Securities
(with copies to the Investor) confirmation that such registration statement has been declared effective by the SEC in the form attached
hereto as Exhibit A. Thereafter, if requested by the Buyer at any time, the Company shall require its counsel to deliver to the
Buyer a written confirmation whether or not the effectiveness of such registration statement has lapsed at any time for any reason (including,
without limitation, the issuance of a stop order) and whether or not the registration statement is current and available to the Buyer
for sale of all of the Registrable Securities.

 

m.
The Company shall take all other reasonable actions necessary to expedite and facilitate disposition by the Investor of Registrable Securities
pursuant to any registration statement.

 

4.
OBLIGATIONS OF THE INVESTOR.

 

a.
The Company shall notify the Investor in writing of the information the Company reasonably requires from the Investor in connection with
any registration statement hereunder. The Investor shall promptly furnish to the Company such information regarding itself, the Registrable
Securities held by it and the intended method of disposition of the Registrable Securities held by it as shall be reasonably required
to effect the registration of such Registrable Securities and shall execute such documents in connection with such registration as the
Company may reasonably request.

 

    5

     

    

 

b.
The Investor agrees to cooperate with the Company as reasonably requested by the Company in connection with the preparation and filing
of any registration statement hereunder.

 

c.
The Investor agrees that, upon receipt of any notice from the Company of the happening of any event or existence of facts of the kind
described in Section 3(f) or the first sentence of 3(e), the Investor will immediately discontinue disposition of Registrable Securities
pursuant to any registration statement(s) covering such Registrable Securities until the Investor’s receipt of the copies of the
supplemented or amended prospectus contemplated by Section 3(f) or the first sentence of 3(e). Notwithstanding anything to the contrary,
the Company shall cause its transfer agent to promptly deliver shares of Common Stock without any restrictive legend in accordance with
the terms of the Purchase Agreement in connection with any sale of Registrable Securities with respect to which an Investor has entered
into a contract for sale prior to the Investor’s receipt of a notice from the Company of the happening of any event of the kind
described in Section 3(f) or the first sentence of Section 3(e) and for which the Investor has not yet settled.

 

5.
EXPENSES OF REGISTRATION.

 

All
reasonable expenses, other than sales or brokerage commissions, incurred in connection with registrations, filings or qualifications
pursuant to Sections 2 and 3, including, without limitation, all registration, listing and qualifications fees, printers and accounting
fees, and fees and disbursements of counsel for the Company, shall be paid by the Company.

 

6.
INDEMNIFICATION.

 

a.
To the fullest extent permitted by law, the Company will, and hereby does, indemnify, hold harmless and defend the Investor, each Person,
if any, who controls the Investor, the members, the directors, officers, partners, employees, agents, representatives of the Investor
and each Person, if any, who controls the Investor within the meaning of the Securities Act or the Securities Exchange Act of 1934, as
amended (the “Exchange Act”) (each, an “Indemnified Person”), against any losses, claims, damages,
liabilities, judgments, fines, penalties, charges, costs, attorneys’ fees, amounts paid in settlement or expenses, joint or several,
(collectively, “Claims”) incurred in investigating, preparing or defending any action, claim, suit, inquiry, proceeding,
investigation or appeal taken from the foregoing by or before any court or governmental, administrative or other regulatory agency, body
or the SEC, whether pending or threatened, whether or not an indemnified party is or may be a party thereto (“Indemnified Damages”),
to which any of them may become subject insofar as such Claims (or actions or proceedings, whether commenced or threatened, in respect
thereof) arise out of or are based upon: (i) any untrue statement or alleged untrue statement of a material fact in the Registration
Statement, any New Registration Statement or any post-effective amendment thereto or in any filing made in connection with the qualification
of the offering under the securities or other “blue sky” laws of any jurisdiction in which Registrable Securities are offered
(“Blue Sky Filing”), or the omission or alleged omission to state a material fact required to be stated therein or
necessary to make the statements therein not misleading, (ii) any untrue statement or alleged untrue statement of a material fact contained
in the final prospectus (as amended or supplemented, if the Company files any amendment thereof or supplement thereto with the SEC) or
the omission or alleged omission to state therein any material fact necessary to make the statements made therein, in light of the circumstances
under which the statements therein were made, not misleading, (iii) any violation or alleged violation by the Company of the Securities
Act, the Exchange Act, any other law, including, without limitation, any state securities law, or any rule or regulation thereunder relating
to the offer or sale of the Registrable Securities pursuant to the Registration Statement or any New Registration Statement or (iv) any
material violation by the Company of this Agreement (the matters in the foregoing clauses (i) through (iv) being, collectively, “Violations”).
The Company shall reimburse each Indemnified Person promptly as such expenses are incurred and are due and payable, for any reasonable
and documented legal fees or other reasonable expenses incurred by them in connection with investigating or defending any such Claim.
Notwithstanding anything to the contrary contained herein, the indemnification agreement contained in this Section 6(a): (i) shall not
apply to a Claim by an Indemnified Person arising out of or based upon a Violation which occurs in reliance upon and in conformity with
information about the Investor furnished in writing to the Company by such Indemnified Person expressly for use in connection with the
preparation of the Registration Statement, any New Registration Statement or any such amendment thereof or supplement thereto, if such
prospectus was timely made available by the Company pursuant to Section 3(c) or Section 3(e); (ii) with respect to any superseded prospectus,
shall not inure to the benefit of any such person from whom the person asserting any such Claim purchased the Registrable Securities
that are the subject thereof (or to the benefit of any person controlling such person) if the untrue statement or omission of material
fact contained in the superseded prospectus was corrected in the revised prospectus, as then amended or supplemented, if such revised
prospectus was timely made available by the Company pursuant to Section 3(c) or Section 3(e), and the Indemnified Person was promptly
advised in writing not to use the incorrect prospectus prior to the use giving rise to a violation and such Indemnified Person, notwithstanding
such advice, used it; (iii) shall not be available to the extent such Claim is based on a failure of the Investor to deliver or to cause
to be delivered the prospectus made available by the Company, if such prospectus was timely made available by the Company pursuant to
Section 3(c) or Section 3(e); and (iv) shall not apply to amounts paid in settlement of any Claim if such settlement is effected without
the prior written consent of the Company, which consent shall not be unreasonably withheld. Such indemnity shall remain in full force
and effect regardless of any investigation made by or on behalf of the Indemnified Person and shall survive the transfer of the Registrable
Securities by the Investor pursuant to Section 9.

 

    6

     

    

 

b.
In connection with the Registration Statement or any New Registration Statement, the Investor agrees to indemnify, hold harmless and
defend, to the same extent and in the same manner as is set forth in Section 6(a), the Company, each of its directors, each of its officers
who signs the Registration Statement or any New Registration Statement, each Person, if any, who controls the Company within the meaning
of the Securities Act or the Exchange Act (collectively and together with an Indemnified Person, an “Indemnified Party”),
against any Claim or Indemnified Damages to which any of them may become subject, under the Securities Act, the Exchange Act or otherwise,
insofar as such Claim or Indemnified Damages 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 about the Investor set forth on Exhibit
B attached hereto and furnished to the Company by the Investor expressly for use in connection with such registration statement;
and, subject to Section 6(d), the Investor will reimburse any legal or other expenses reasonably incurred by them in connection with
investigating or defending any such Claim; provided, however, that the indemnity agreement contained in this Section 6(b) and the agreement
with respect to contribution contained in Section 7 shall not apply to amounts paid in settlement of any Claim if such settlement is
effected without the prior written consent of the Investor, which consent shall not be unreasonably withheld; provided, further, however,
that the Investor shall be liable under this Section 6(b) for only that amount of a Claim or Indemnified Damages as does not exceed the
net proceeds to the Investor as a result of the sale of Registrable Securities pursuant to such registration statement. Such indemnity
shall remain in full force and effect regardless of any investigation made by or on behalf of such Indemnified Party and shall survive
the transfer of the Registrable Securities by the Investor pursuant to Section 9.

 

c.
Promptly after receipt by an Indemnified Person or Indemnified Party under this Section 6 of notice of the commencement of any action
or proceeding (including any governmental action or proceeding) involving a Claim, such Indemnified Person or Indemnified Party shall,
if a Claim in respect thereof is to be made against any indemnifying party under this Section 6, 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 control of the defense thereof
with counsel mutually satisfactory to the indemnifying party and the Indemnified Person or the Indemnified Party, as the case may be;
provided, however, that an Indemnified Person or Indemnified Party shall have the right to retain its own counsel with the fees and expenses
to be paid by the indemnifying party, if, in the reasonable opinion of counsel retained by the indemnifying party, the representation
by such counsel of the Indemnified Person or Indemnified Party and the indemnifying party would be inappropriate due to actual or potential
differing interests between such Indemnified Person or Indemnified Party and any other party represented by such counsel in such proceeding.
The Indemnified Party or Indemnified Person shall cooperate fully with the indemnifying party in connection with any negotiation or defense
of any such action or claim by the indemnifying party and shall furnish to the indemnifying party all information reasonably available
to the Indemnified Party or Indemnified Person which relates to such action or claim. The indemnifying party shall keep the Indemnified
Party or Indemnified Person fully apprised at all times as to the status of the defense or any settlement negotiations with respect thereto.
No indemnifying party shall be liable for any settlement of any action, claim or proceeding effected without its written consent, provided,
however, that the indemnifying party shall not unreasonably withhold, delay or condition its consent. No indemnifying party shall, without
the consent of the Indemnified Party or Indemnified Person, consent to entry of any judgment or enter into any settlement or other compromise
which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party or Indemnified
Person of a release from all liability in respect to such claim or litigation. Following indemnification as provided for hereunder, the
indemnifying party shall be subrogated to all rights of the Indemnified Party or Indemnified Person with respect to all third parties,
firms or corporations relating to the matter for which indemnification has been made. The failure to deliver written notice to the indemnifying
party within a reasonable time of the commencement of any such action shall not relieve such indemnifying party of any liability to the
Indemnified Person or Indemnified Party under this Section 6, except to the extent that the indemnifying party is prejudiced in its ability
to defend such action.

 

    7

     

    

 

d.
The indemnification required by this Section 6 shall be made by periodic payments of the amount thereof during the course of the investigation
or defense, as and when bills are received or Indemnified Damages are incurred.

 

e.
The indemnity agreements contained herein shall be in addition to (i) any cause of action or similar right of the Indemnified Party or
Indemnified Person against the indemnifying party or others, and (ii) any liabilities the indemnifying party may be subject to pursuant
to the law.

 

7.
CONTRIBUTION.

 

To
the extent any indemnification by an indemnifying party is prohibited or limited by law, the indemnifying party agrees to make the maximum
contribution with respect to any amounts for which it would otherwise be liable under Section 6 to the fullest extent permitted by law;
provided, however, that: (i) no seller of Registrable Securities guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Securities Act) shall be entitled to contribution from any seller of Registrable Securities who was not guilty of fraudulent
misrepresentation; and (ii) contribution by any seller of Registrable Securities shall be limited in amount to the net amount of proceeds
received by such seller from the sale of such Registrable Securities.

 

8.
REPORTS AND DISCLOSURE UNDER THE SECURITIES ACT.

 

With
a view to making available to the Investor the benefits of Rule 144 promulgated under the Securities Act or any other similar rule or
regulation of the SEC that may at any time permit the Investor to sell securities of the Company to the public without registration (“Rule
144”), the Company agrees, at the Company’s sole expense, to:

 

    8

     

    

 

a.
make and keep public information available, as those terms are understood and defined in Rule 144;

 

b.
file with the SEC in a timely manner all reports and other documents required of the Company under the Securities Act and the Exchange
Act so long as the Company remains subject to such requirements and the filing of such reports and other documents is required for the
applicable provisions of Rule 144;

 

c.
furnish to the Investor so long as the Investor owns Registrable Securities, promptly upon request, (i) a written statement by the Company
that it has complied with the reporting and or disclosure provisions of Rule 144, the Securities Act and the Exchange Act, (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 to permit the Investor to sell such securities pursuant to Rule 144 without registration;
and

 

d.
take such additional action as is reasonably requested by the Investor to enable the Investor to sell the Registrable Securities pursuant
to Rule 144, including, without limitation, delivering all such legal opinions, consents, certificates, resolutions and instructions
to the Company’s Transfer Agent as may be reasonably requested from time to time by the Investor and otherwise fully cooperate
with Investor and Investor’s broker to effect such sale of securities pursuant to Rule 144.

 

The
Company agrees that damages may be an inadequate remedy for any breach of the terms and provisions of this Section 8 and that Investor
shall, whether or not it is pursuing any remedies at law, be entitled to equitable relief in the form of a preliminary or permanent injunctions,
without having to post any bond or other security, upon any breach or threatened breach of any such terms or provisions.

 

9.
ASSIGNMENT OF REGISTRATION RIGHTS.

 

The
Company shall not assign this Agreement or any rights or obligations hereunder without the prior written consent of the Investor. The
Investor may not assign its rights under this Agreement without the written consent of the Company, other than to an affiliate of the
Investor controlled by Jonathan Cope or Josh Scheinfeld.

 

10.
AMENDMENT OF REGISTRATION RIGHTS.

 

No
provision of this Agreement may be amended or waived by the parties from and after the date that is one (1) Business Day immediately
preceding the initial filing of the Registration Statement with the SEC. Subject to the immediately preceding sentence, no provision
of this Agreement may be (i) amended other than by a written instrument signed by both parties hereto or (ii) waived other than in a
written instrument signed by the party against whom enforcement of such waiver is sought. Failure of any party to exercise any right
or remedy under this Agreement or otherwise, or delay by a party in exercising such right or remedy, shall not operate as a waiver thereof.

 

    9

     

    

 

11.
MISCELLANEOUS.

 

a.
A Person is deemed to be a holder of Registrable Securities whenever such Person owns or is deemed to own of record such Registrable
Securities. If the Company receives conflicting instructions, notices or elections from two or more Persons with respect to the same
Registrable Securities, the Company shall act upon the basis of instructions, notice or election received from the registered owner of
such Registrable Securities.

 

b.
Any notices, consents, waivers or other communications required or permitted to be given under the terms of this Agreement must be in
writing and will be deemed to have been delivered: (i) upon receipt, when delivered personally; (ii) upon receipt, when sent by facsimile
or email (provided confirmation of transmission is mechanically or electronically generated and kept on file by the sending party); or

the party to receive the same. The addresses, email addresses and facsimile numbers for such communications shall be:

Re:
Vyant Bio, Inc.

 

Ladies
and Gentlemen:

 

We
are counsel to Vyant Bio, Inc., a Delaware corporation (the “Company”), and have represented the Company in connection
with that certain Purchase Agreement, dated as of March 28, 2022 (the “Purchase Agreement”), entered into by and between
the Company and Lincoln Park Capital Fund, LLC (the “Buyer”), pursuant to which the Company has issued to the Buyer
an aggregate of 405,953 shares of the Company’s common stock, $0.0001 par value per share (the “Common Stock”)
as payment of a commitment fee for its commitment to purchase shares under the Purchase Agreement, and may in the future issue to the
Buyer up to Fifteen Million Dollars ($15,000,000) of Common Stock from the Company from time to time at the direction of the Company,
upon the terms and subject to the conditions set forth in the Purchase Agreement. In connection with the transactions contemplated by
the Purchase Agreement, the Company has registered with the U.S. Securities and Exchange Commission (the “SEC”) the
following shares of Common Stock:

 

	 	(1)	405,953 shares of Common Stock that have been issued to the
Buyer upon execution of the Purchase Agreement as payment of a commitment fee (the “Commitment Shares”); and
	 	 	 
	 	(2)	5,390,780 shares of Common Stock to be issued to the Buyer
upon purchase by the Buyer from the Company at the Company’s direction from time to time in accordance with the terms of the Purchase
Agreement (the “Purchase Shares”).

 

Pursuant
to the Purchase Agreement, the Company also has entered into a Registration Rights Agreement, dated as of March 28, 2022, with the Buyer
(the “Registration Rights Agreement”) pursuant to which the Company agreed, among other things, to register the Purchase
Shares and the Commitment Shares under the Securities Act of 1933, as amended (the “Securities Act”). In connection
with the Company’s obligations under the Purchase Agreement and the Registration Rights Agreement, on [_________], 2022, the Company
filed a Registration Statement on Form S-1 (File No. 333-[_________]) (the “Registration Statement”) with the SEC
relating to the resale of the Purchase Shares and the Commitment Shares.

 

In
connection with the foregoing, we advise you that the SEC has entered an order declaring the Registration Statement effective under the
Securities Act at [_____] [A.M./P.M.] on [__________], 2022 and we have no knowledge, after review of the stop order notification website
maintained by the SEC, that any stop order suspending its effectiveness has been issued or that any proceedings for that purpose are
pending before, or threatened by, the SEC and the Purchase Shares and the Commitment Shares are available for resale under the Securities
Act pursuant to the Registration Statement and may be issued without any restrictive legend or stop transfer orders maintained against
them.

 

	 	Very
    truly yours,
	 	[Company
    Counsel]

Mining Company

DESCRIPTION
OF REGISTRANT’S SECURITIES

 

Goldrich
Mining Company (the “Company”) is authorized to issue 750,000,000 shares of common stock, $0.10 par value, and 10,000,000
shares of preferred stock, no par value.

 

Common
Stock

 

Each
holder of the Company’s common stock is entitled to one vote per share in the election of directors and on all other matters submitted
to the vote of shareholders. No holder of the Company’s common stock may cumulate votes in voting for our directors.

 

Subject
to the rights of the holders of any the Company’s preferred stock that may be outstanding from time to time, each share of common
stock will have an equal and ratable right to receive dividends as may be declared by the Company’s board of directors out of funds
legally available for the payment of dividends, and, in the event of liquidation, dissolution or winding up of the Company, will be entitled
to share equally and ratably in the assets available for distribution to the Company’s shareholders. No holder of the Company’s
common stock will have any preemptive right to subscribe for any of the Company’s securities.

 

We
have not paid any dividends and do not anticipate the payment of dividends on our common stock.

 

The
Company’s common stock is quoted under the symbol “GRMC” on the OTCQB of the OTC Markets. The OTCQB is a network of
security dealers who buy and sell stock. The dealers are connected by a computer network which provides information on current “bids”
and “asks” as well as volume information. The OTCQB is not considered a “national securities exchange.”
