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 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, subject to the aggregate number of authorized
shares of the Company’s Common Stock then available for issuance in its Certificate of Incorporation. 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 commercially reasonable 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 (with the prior
consent, which shall not be unreasonably withheld, of 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 prospectuses 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 commercially reasonable 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 Investor 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. 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 commercially reasonable 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 commercially reasonable 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 issuance of the Registrable Securities to be offered pursuant
to any Registration Statement, it being agreed that such Registrable Securities shall be issued as DWAC Shares and 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) promptly 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 commercially reasonable 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 the 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 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.


 


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.


 




    	 	5	 



     


    

 


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 a
notice regarding the resolution or withdrawal of the stop order or suspension as contemplated by Section 3(f) or the supplemented
or amended prospectus as contemplated by 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, 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 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 any 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 or prospectus contained therein, if such Registration
Statement, New Registration Statement or amendment thereof or supplement thereto or prospectus contained therein 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 Indemnified Person from whom the Indemnified Person asserting any such Claim purchased the Registrable Securities
that are the subject thereof (or to the benefit of any person controlling such Indemnified 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 any Indemnified Party 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 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 ACTS.


 


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:


 



 


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 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 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 seek 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, in which case the assignee must agree in writing to be bound by the terms and conditions of
this Agreement.


 


10.           AMENDMENT
OF REGISTRATION RIGHTS.

Re: iBio, Inc.


 


Ladies and Gentlemen:


 


We are counsel to iBio,
Inc., a Delaware corporation (the “Company”), and have represented the Company in connection with that certain
Purchase Agreement, dated as of July 24, 2017 (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 3,700,000 shares of the Company's common stock, par value $0.001 per share (the “Common Stock”), and may
in the future issue to the Buyer shares of Common Stock in an amount up to an additional Fifteen Million Dollars ($15,000,000),
in accordance with the terms of 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)	2,500,000 shares of Common Stock that have been issued
to the Buyer on the date of the Purchase Agreement (the “Initial Purchase Shares”);



 


		(2)	14,100,000 shares of Common Stock to be issued to the Buyer
upon purchase by the Buyer from the Company from time to time in accordance with the terms of the Purchase Agreement (the “Purchase
Shares”); and



 


		(3)	1,200,000 shares of Common Stock that have been issued
to the Buyer as a commitment fee on the date of the Purchase Agreement (the “Commitment Shares”).



 


Pursuant to the Purchase
Agreement, the Company also has entered into a Registration Rights Agreement, dated as of July 24, 2017, with the Buyer (the “Registration
Rights Agreement”) pursuant to which the Company agreed, among other things, to register the Initial Purchase Shares,
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 [_________],
2017, the Company filed a Registration Statement (File No. 333-[_________]) (the “Registration Statement”) with
the SEC relating to the resale of the Initial Purchase Shares, 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 [__________], 2017 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 Initial Purchase Shares, 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,
	 	 
	 	By:
