its respective subsidiaries) who have rights to any Intellectual Property, except for customary reversionary rights of
third-party licensors, and the conduct of the Company’s or any of its subsidiaries businesses as currently conducted or

and all such agreements are in full force and effect. The products or product candidates described in the SEC Reports (each a
“Company Product”) as under development by the Company or any of its subsidiaries fall within the
scope of the claims of one or more patents or patent applications owned by, or exclusively licensed to, the Company or any of
their respective subsidiaries, the rights of the Company or any of its subsidiaries under which entitle (or in the case of
patent applications, once issued, would entitle) the Company or any of its subsidiaries to claim in good faith that a third
party should cease the manufacture, use, sale or importation of such Company Product. The Company has taken commercially
reasonable efforts to protect, enforce and maintain the material Intellectual Property. All present or former employees,
consultants or independent contractors involved the development of any material Intellectual Property have executed written
agreements under which he, she or it assigns all rights to such Intellectual Property to the Company or any of its
subsidiaries and agrees to protect the Company’s and its subsidiaries’ trade secrets and other confidential

Restrictions. Each Investor understands that the Company (or its transfer agent) may, as a condition to the transfer of
the Shares, require that the request for transfer be accompanied by an opinion of counsel reasonably satisfactory to the
Company, to the effect that the proposed transfer does not result in a violation of the Securities Act or by Rule 144 under
the Securities Act, unless such transfer is covered by an effective registration statement. It is understood that the
certificates evidencing the Shares may bear substantially the following legend:

 

“THESE SECURITIES HAVE NOT
BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933. THEY MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED OR HYPOTHECATED IN THE ABSENCE
OF A REGISTRATION STATEMENT IN EFFECT WITH RESPECT TO THE SECURITIES UNDER SUCH ACT OR AN OPINION OF COUNSEL REASONABLY SATISFACTORY
TO THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED UNDER SUCH ACT OR UNLESS SOLD PURSUANT TO RULE 144 OF SUCH ACT.”

 

    - 12 -

     

    

 

The Company acknowledges and agrees that an
Investor may from time to time pledge, and/or grant a security interest in, some or all of the legended Shares in compliance with
applicable securities laws, pursuant to a bona fide margin agreement in compliance with a bona fide margin loan with a nationally
recognized NASDAQ-member prime broker. Such a pledge would not be subject to approval or consent of the Company and no legal opinion
of legal counsel to the pledgee, secured party or pledgor shall be required in connection with the pledge. No notice shall be required
of such pledge, but Investor must notify the Company as promptly as practicable prior to any such subsequent transfer or foreclosure.
Each Investor acknowledges that the Company shall not be responsible for any pledges relating to, or the grant of any security
interest in, any of the Shares or for any agreement, understanding or arrangement between any Investor and its pledgee or secured
party. The Company will use commercially reasonable efforts (and in any event, at the appropriate Investor’s expense) to
execute and deliver such reasonable documentation as a pledgee or secured party of Shares may reasonably request in connection
with a pledge or transfer of the Shares. Each Investor acknowledges and agrees that, except as otherwise provided in Section
7.2, any Shares subject to a pledge or security interest as contemplated by this Section 7.1 shall continue to bear
the legend set forth in this Section 7.1 and be subject to the restrictions on transfer set forth in this Section 7.1.

 

7.2.           
Unlegended Certificates. The Company shall be obligated to reissue unlegended certificates representing the Shares
(x) subject to the receipt of standard written documentation reasonably acceptable to the Company’s counsel provided by the
holder pursuant to Rule 144, which, for the avoidance of doubt, shall not include a legal opinion, and a representation that the
holder is not an Affiliate of the Company, within five (5) trading days of the request of any holder thereof at such time as the
holding period under Rule 144 or another applicable exemption from the registration requirements of the Securities Act for a transfer
of such Shares to the public has been satisfied or (y) within five (5) trading days of a registration statement being declared
effective for the resale of such Shares.

8.                 
Registration Rights.

 

8.1.           
Registration Statements.

 

(a)              
 Filing of Registration Statement. On or prior to the 10th Business Day following the Closing Date, the Company shall
prepare and submit to the Commission one draft Registration Statement on Form S-3 (provided, however, that there shall be no obligation
to effect such registration through an underwritten offering), covering the resale of all of the Registrable Securities, and shall
use commercially reasonable efforts to cause such Registration Statement to be declared effective as promptly as reasonably practicable
thereafter, but in any event on or prior to (i) in the event that the Registration Statement is not subject to a full review by
the Commission, sixty (60) calendar days after the Closing Date or (ii) in the event that the Registration Statement is subject
to a full review by the Commission, ninety (90) calendar days after the Closing Date. Such Registration Statement (and each amendment
or supplement thereto, and each request for acceleration of effectiveness thereof) shall be provided in accordance with Section
8.2(c) to the Investors and their counsel prior to its filing or other submission.

 

(b)              
Expenses. The Company shall pay all Company expenses associated with effecting the registration of the Registrable
Securities, including filing and printing fees, the Company’s counsel (but excluding any fees of any counsel to the Investors)
and accounting fees and expenses, costs associated with clearing the Registrable Securities for sale under applicable state securities
laws and listing fees, but excluding discounts, commissions, fees of underwriters, selling brokers, dealer managers or similar
securities industry professionals with respect to the Registrable Securities being sold.

 

(c)              
Effectiveness.

 

(1)              
The Company shall respond as promptly as reasonably practicable to any and all comments made by the staff of the Commission
on such Registration Statement, and shall submit to the Commission, with three (3) Business Days after the Company learns that
no review of such Registration Statement will be made by the staff of the Commission or that the staff of the Commission has no
further comments on such Registration Statement, as the case may be, a request for acceleration of the effectiveness of such Registration
Statement to a time and date not later than two (2) Business Days after the submission of such request. The Company shall notify
the Investors by e-mail as promptly as reasonably practicable, and in any event, within twenty-four (24) hours, after such Registration
Statement is declared effective and shall simultaneously provide or make available to the Investors copies of any related Prospectus
to be used in connection with the sale or other disposition of the securities covered thereby.

 

    - 14 -

     

    

 

(2)               At
any time and from time to time, the Company may suspend the use of any Prospectus included in such Registration Statement for
such period(s) as it determines in its sole discretion in the event that the Company determines in good faith that such
suspension is necessary or appropriate to (A) delay the disclosure of material non-public information concerning the Company,
the disclosure of which at the time is not, in the good faith opinion of the Company, in the best interests of the Company,
(B) amend or supplement such Registration Statement or the related Prospectus so that such Registration Statement or
Prospectus will not include an untrue statement of a material fact or omit to state a material fact required to be stated
therein or necessary to make the statements therein, in the case of the Prospectus, in light of the circumstances under which
they were made, not misleading, or (C) without limiting the generality of the foregoing, facilitate proposed offerings of
Company securities (an “Allowed Delay”); provided, that the Allowed Delays, in the
aggregate, shall not exceed ninety (90) days (which need not be consecutive days) in the aggregate in any twelve (12) month
period; provided, further, that the Company shall promptly (a) notify each Investor in writing of the
commencement of an Allowed Delay, but shall not (without the prior written consent of an Investor) disclose to such Investor
any material non-public information giving rise to an Allowed Delay, and (b) advise the Investors in writing to cease all
sales under the Registration Statement until the end of the Allowed Delay. In the event of the Company’s breach of its
obligations with respect to clause (A) of this Section 8.1(c)(2), each Investor shall be entitled to a payment (with respect
to the Registrable Securities of each such Investor), as compensation and not as a penalty, of 0.25% of the Liquidated
Damages Multiplier per 60-day period, which shall accrue daily, for the first 60 days following the 90th day, increasing by
an additional 0.25% of the Liquidated Damages Multiplier per 60-day period, which shall accrue daily, for each subsequent 60
days (i.e., 0.5% for 61-120 days, 0.75% for 121-180 days and 1.0% thereafter), up to a maximum of 1.00% of the Liquidated
Damages Multiplier per 60-day period (the “Liquidated Damages”). The Liquidated Damages payable
pursuant to the immediately preceding sentence shall be payable within twenty Business Days after the end of each such 60-day
period. Any Liquidated Damages shall be paid to each Investor in immediately available funds. The accrual of Liquidated
Damages to an Investor shall cease at the earlier of (i) the cessation of such suspension, (ii) when such Investor no longer
holds Registrable Securities, or (iii) the expiration of any obligation to maintain such Registration Statement or Prospectus
pursuant hereto, and any payment of Liquidated Damages shall be prorated for any period of less than 60 days in which the
payment of Liquidated Damages ceases. The Company may request a waiver of the Liquidated Damages, which may be granted by the
Required Investors on behalf of all of the Investors, and notwithstanding the failure to obtain such waiver, each Investor
may individually grant or withhold its consent to such request in its discretion. “Liquidated Damages
Multiplier” means the product of the Purchase Price times the number of Registrable Securities purchased by
such Investor that may not be disposed of without restriction and without the need for current public information pursuant to
any section of Rule 144 (or any similar provision then in effect) under the Securities Act. The Investors acknowledge and
agree that the Investor’s actual harm caused by a breach of the Company’s obligations with respect to clause (A)
of this Section 8.1(c)(2) would be impossible or very difficult to accurately estimate or prove, and that the Liquidated
Damages are a reasonable estimate of the anticipated or actual harm that might arise from such breach. The Company’s
payment of the Liquidated Damages is the Company’s sole liability and entire obligation, and the Investor’s
exclusive monetary remedy, for any such breach.

8.2.           
Company Obligations. The Company shall use commercially reasonable efforts to effect the registration of the Registrable
Securities in accordance with the terms hereof, and pursuant thereto the Company shall:

 

(a)              
use commercially reasonable efforts to cause such Registration Statement, or a successor Registration Statement, to become
effective and to remain continuously effective (other than during an Allowed Delay) for a period (the “Effectiveness
Period”) that will terminate upon the earlier of (i) the date on which all Registrable Securities covered by such
Registration Statement, as amended from time to time, no longer constitute Registrable Securities, and (ii) three (3) years from
the Closing Date;

 

(b)              
use commercially reasonable efforts to prepare and file with the Commission such amendments and post-effective amendments

the Registrable Securities covered thereby;

 

(c)

for incorporation in such Registration Statements or amendments and supplements thereto in good faith;

 

(d)               furnish

may reasonably request (and in any event within two (2) Business Days of the Company’s request), to respond to requests by

of the Company’s other obligations under this Agreement, subject to the provisions of this Section 8.4, the
Company shall indemnify and hold harmless each Investor, each of its (as applicable) directors, officers, shareholders,
employees and agents (and any other Persons with a functionally equivalent role of a Person holding such titles
notwithstanding the lack of such title or any other title) and each Person, if any, who controls the Investor (within the
meaning of Section 15 of the Securities Act or Section 20(a) of the Exchange Act) (each, an “Investor
Party”), from and against all losses, liabilities, obligations, claims, contingencies, damages, costs and
expenses (including all judgments, amounts paid in settlement, court costs, reasonable attorneys’ fees and costs of
defense and investigation) (collectively, “Damages”) that any Investor Party may suffer or incur as
a result of or relating to any action, suit, claim or proceeding (including for these purposes a derivative action brought on
behalf of the Company) instituted against such Investor Party arising out of or resulting from (i) any untrue or alleged
untrue statement of a material fact contained in any Registration Statement under which such Registrable Securities are
registered or sold under the Securities Act (including any final, preliminary or summary Prospectus contained therein or any
amendment thereof or supplement thereto or any documents incorporated by reference therein) or any other disclosure document
produced by or on behalf of the Company including any report and other document filed under the Exchange Act or (ii) any
omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the
statements therein (in the case of a Prospectus or preliminary Prospectus, in light of the circumstances under which they
were made) not misleading; provided, however, that the foregoing indemnity will not apply to any
Damages to the extent, but only to the extent, that such Damages arise out of or result from any untrue statement or omission
contained in any information relating to such Investor furnished in writing by an Investor Party (other than another
Investor) to the Company expressly for inclusion in a Registration Statement.

 

(b)               Indemnification
by the Investors. In consideration of each Investor’s execution and delivery of this Agreement and in addition to
all of the Investor’s other obligations under this Agreement, subject to the provisions of this Section 8.4,
each Investor shall indemnify and hold harmless the Company, each of its directors, officers, shareholders, employees and
agents (and any other Persons with a functionally equivalent role of a Person holding such titles notwithstanding the lack of
such title or any other title), each Person, if any, who controls the Company (within the meaning of Section 15 of the
Securities Act or Section 20(a) of the Exchange Act) (each, a “Company Party”), from and against
all Damages that any Company Party may suffer or incur as a result of or relating to any action, suit, claim or proceeding
(including for these purposes a derivative action brought on behalf of the Company) instituted against such Company Party to
the extent arising out of or resulting from (i) any untrue statement of a material fact in any Registration Statement under
which such Registrable Securities were registered or sold under the Securities Act (including any final, preliminary or
summary Prospectus contained therein or any amendment thereof or supplement thereto or any documents incorporated by
reference therein) or (ii) any omission to state therein a material fact required to be stated therein or necessary to make
the statements therein (in the case of a Prospectus or preliminary Prospectus, in light of the circumstances under which they
were made) not misleading, in each case to the extent that such untrue statement or omission is contained in any information
relating to such Investor furnished in writing by an Investor Party (other than another Investor) to the Company expressly
for inclusion in a Registration Statement. Notwithstanding anything herein to the contrary, any Investor shall be liable
under this Section 8.4(b) for only that amount of Damages as does not exceed the net proceeds to such Investor as a result of
the sale of Registrable Securities pursuant to such Registration Statement.

 

    - 19 -

     

    

 

(c)              
Promptly after receipt by an indemnified party under this Section 8.4 of notice of the commencement of any action
(including any governmental action) for which a party may be entitled to indemnification hereunder, such indemnified party shall,
if a claim in respect thereof is to be made against any indemnifying party under this Section 8.4, give the indemnifying
party notice of the commencement thereof. The indemnifying party will have the right to participate in such action and, to the
extent the indemnifying party so desires, participate jointly with any other indemnifying party to which notice has been given,
and to assume the defense thereof with counsel mutually satisfactory to the parties; provided, however, that an indemnified
party (together with all other indemnified parties that may be represented without conflict by one counsel) will 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 differing interests between such indemnified
party and any other party represented by such counsel in such action. The failure to give 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
party under this Section 8.4, unless and to the extent such failure prejudices the indemnifying party’s ability to
defend such action. If the indemnifying party assumes the defense of a claim pursuant to this Section 8.4(c), (x) the indemnifying
party shall not be subject to any liability for any settlement made without its prior written consent, and (y) the indemnifying
party shall not settle such claim unless the settlement includes an unconditional release of the indemnified party from all liability
with respect to all claims that are the subject of the proceeding. If such defense is not assumed by the indemnifying party, the
indemnifying party will not be subject to any liability for any settlement made without its prior written consent.

 

(d)               To
provide for just and equitable contribution to joint liability under the Securities Act in any case in which either (i) any
party otherwise entitled to indemnification hereunder makes a claim for indemnification pursuant to this Section 8.4 but
it is judicially determined (by the entry of a final judgment or decree by a court of competent jurisdiction and the
expiration of time to appeal or the denial of the last right of appeal) that such indemnification may not be enforced in such
case, notwithstanding the fact that this Section 8.4 provides for indemnification in such case, or (ii) contribution
under the Securities Act may be required on the part of any party hereto for which indemnification is provided under this Section
8.4, then, and in each such case, such parties shall contribute to the aggregate losses, claims, damages, liabilities, or
expenses to which they may be subject (after contribution from others) in such proportion as is appropriate to reflect the
relative fault of each of the indemnifying party and the indemnified party in connection with the statements, omissions, or
other actions that resulted in such loss, claim, damage, liability, or expense, as well as to reflect any other relevant
equitable considerations. The relative fault of the indemnifying party and of the indemnified party will be determined by
reference to, among other things, whether the untrue or allegedly untrue statement of a material fact, or the omission or
alleged omission of 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; provided, however, that, in any such case, (x) no Investor will be required to
contribute any amount in excess of the public offering price of all such Registrable Securities offered and sold by such
Investor pursuant to such registration statement, and (y) no Person guilty of fraudulent misrepresentation (within the
meaning of Section 11(f) of the Securities Act) will be entitled to contribution from any Person who was not guilty of such
fraudulent misrepresentation.
