Section 2.

Resale Registration
Rights

 

2.1.    Resale
Registration Rights.

 

(a)    Following
demand by the Investors holding a majority of the Registrable Securities, the Company shall file with the Commission a Registration
Statement on Form S-3 (except if the Company is not then eligible to register for resale the Registrable Securities on
Form S-3, in which case such registration shall be on another appropriate form in accordance with the Securities Act)
covering the resale of all of the Registrable Securities by the Investors (the “Resale Registration Shelf”),
and the Company shall file such Resale Registration Shelf as promptly as reasonably practicable following such demand, and in any
event within sixty (60) days of such demand. Such Resale Registration Shelf shall include a “final” prospectus,
including the information required by Item 507 of Regulation S-K of the Securities Act, as provided by the Investors
in accordance with Section 2.7. Notwithstanding the foregoing, before filing the Resale Registration Shelf, the Company shall
furnish to the Investors a copy of the Resale Registration Shelf and afford the Investors an opportunity to review and comment
on the Resale Registration Shelf. The Company’s obligation pursuant to this Section 2.1(a) is conditioned
upon the Investors providing the information contemplated in Section 2.7.

 

(b)    The
Company shall use its reasonable best efforts to cause the Resale Registration Shelf and related prospectuses to become effective
as promptly as practicable after filing. The Company shall use its reasonable best efforts to cause such Registration Statement
to remain effective under the Securities Act until the earlier of the date (i) all Registrable Securities covered by the Resale
Registration Shelf have been sold or may be sold freely without limitations or restrictions as to volume or manner of sale pursuant
to Rule 144 or (ii) all Registrable Securities covered by the Resale Registration Shelf otherwise cease to be Registrable
Securities pursuant to the definition of Registrable Securities. The Company shall promptly, and within two (2) business
days after the Company confirms effectiveness of the Resale Registration Shelf with the Commission, notify the Investors of the
effectiveness of the Resale Registration Shelf.

 

(c)    Notwithstanding
anything contained herein to the contrary, the Company shall not be obligated to effect, or to take any action to effect, a registration
pursuant to Section 2.1(a):

 

(i)    if
the Company has and maintains an effective Registration Statement on Form S-3ASR that provides for the resale of an unlimited
number of securities by selling stockholders (a “Company Registration Shelf”);

 

(ii)   during
the period forty-five (45) days prior to the Company’s good faith estimate of the date of filing of a Company Registration
Shelf; or

 

    

     

    

 

(iii)   if
the Company has caused a Registration Statement to become effective pursuant to this Section 2.1.

 

(d)    If
the Company has a Company Registration Shelf in place at any time in which the Investors holding a majority of the Registrable
Securities make a demand pursuant to Section 2.1(a), the Company shall file with the Commission, as promptly as
practicable, and in any event within fifteen (15) business days after such demand, a “final” prospectus supplement
to its Company Registration Shelf covering the resale of all of the Registrable Securities by the Investors (the “Prospectus”); provided, however,
that the Company shall not be obligated to file more than one Prospectus pursuant to this Section 2.1(d). The
Prospectus shall include the information required under Item 507 of Regulation S-K of the Securities Act, which information
shall be provided by the Investors in accordance with Section 2.7. Notwithstanding the foregoing, before filing the
Prospectus, the Company shall furnish to the Investors a copy of the Prospectus and afford the Investors an opportunity to review
and comment on the Prospectus.

 

(e)    Deferral
and Suspension. At any time after being obligated to file a Resale Registration Shelf or Prospectus, or after any Resale Registration
Shelf has become effective or a Prospectus filed with the Commission, the Company may defer the filing of or suspend the use of
any such Resale Registration Shelf or Prospectus, upon giving written notice of such action to the Investors with a certificate
signed by the Principal Executive Officer of the Company stating that in the good faith judgment of the Board, the filing or use
of any such Resale Registration Shelf or Prospectus covering the Registrable Securities would be seriously detrimental to the Company
or its stockholders at such time and that the Board concludes, as a result, that it is in the best interests of the Company and
its stockholders to defer the filing or suspend the use of such Resale Registration Shelf or Prospectus at such time. The Company
shall have the right to defer the filing of or suspend the use of such Resale Registration Shelf or Prospectus for a period of
not more than one hundred twenty (120) days from the date the Company notifies the Investors of such deferral or suspension; provided that
the Company shall not exercise the right contained in this Section 2.1(e) more than once in any twelve month
period. In the case of the suspension of use of any effective Resale Registration Shelf or Prospectus, the Investors, immediately
upon receipt of notice thereof from the Company, shall discontinue any offers or sales of Registrable Securities pursuant to such
Resale Registration Shelf or Prospectus until advised in writing by the Company that the use of such Resale Registration Shelf
or Prospectus may be resumed. In the case of a deferred Prospectus or Resale Registration Shelf filing, the Company shall provide
prompt written notice to the Investors of (i) the Company’s decision to file or seek effectiveness of the Prospectus
or Resale Registration Shelf, as the case may be, following such deferral and (ii) in the case of a Resale Registration Shelf,
the effectiveness of such Resale Registration Shelf. In the case of either a suspension of use of, or deferred filing of, any Resale
Registration Shelf or Prospectus, the Company shall not, during the pendency of such suspension or deferral, be required to take
any action hereunder (including any action pursuant to Section 2.2 hereof) with respect to the registration
or sale of any Registrable Securities pursuant to any such Resale Registration Shelf, Company Registration Shelf or Prospectus.

 

(f)    Other
Securities. Subject to Section 2.2(e) below, any Resale Registration Shelf or Prospectus may
include Other Securities, and may include securities of the Company being sold for the account of the
Company; provided such Other Securities are excluded first from such Registration Statement in order to
comply with any applicable laws or request from any Government Entity, Nasdaq or any applicable listing agency. For the
avoidance of doubt, no Other Securities may be included in an underwritten offering pursuant
to Section 2.2 without the consent of the Investors.

 

    

     

    

 

2.2.    Sales
and Underwritten Offerings of the Registrable Securities.

 

(a)    Notwithstanding
any provision contained herein to the contrary, the Investors, collectively, shall and subject to the limitations set forth in
this Section 2.2, be permitted one underwritten public offering per calendar year, but no more than two underwritten
public offerings total to effect the sale or distribution of Registrable Securities.

 

(b)    If
the Investors intend to effect an underwritten public offering pursuant to a Resale Registration Shelf or Company Registration
Shelf to sell or otherwise distribute Registrable Securities, they shall so advise the Company and provide as much notice to the
Company as reasonably practicable (and in any event not less than fifteen (15) business days prior to the Investors’
request that the Company file a prospectus supplement to a Resale Registration Shelf or Company Registration Shelf).

 

(c)    In
connection with any offering initiated by the Investors pursuant to this Section 2.2 involving an underwriting
of shares of Registrable Securities, the Investors shall be entitled to select the underwriter or underwriters for such offering,
subject to the consent of the Company, such consent not to be unreasonably withheld, conditioned or delayed.

 

(d)    In
connection with any offering initiated by the Investors pursuant to this Section 2.2 involving an underwriting
of shares of Registrable Securities, the Company shall not be required to include any of the Registrable Securities in such underwriting
unless the Investors (i) enter into an underwriting agreement in customary form with the underwriter or underwriters, (ii) accept
customary terms in such underwriting agreement with regard to representations and warranties relating to ownership of the Registrable
Securities and authority and power to enter into such underwriting agreement and (iii) complete and execute all questionnaires,
powers of attorney, custody agreements, indemnities and other documents as may be requested by such underwriter or underwriters.
Further, the Company shall not be required to include any of the Registrable Securities in such underwriting if (Y) the underwriting
agreement proposed by the underwriter or underwriters contains representations, warranties or conditions that are not reasonable
in light of the Company’s then-current business or (Z) the underwriter, underwriters or the Investors require the Company
to participate in any marketing, road show or comparable activity that may be required to complete the orderly sale of shares by
the underwriter or underwriters.

 

(e)    If
the total amount of securities to be sold in any offering initiated by the Investors pursuant to
this Section 2.2 involving an underwriting of shares of Registrable Securities exceeds the amount that
the underwriters determine in their sole discretion is compatible with the success of the offering, then the Company shall be
required to include in the offering only that number of such securities, including Registrable Securities (subject in each
case to the cutback provisions set forth in this Section 2.2(e)), that the underwriters and the Company
determine in their sole discretion shall not jeopardize the success of the offering. If the underwritten public offering has
been requested pursuant to Section 2.2(a) hereof, the number of shares that are entitled to be included
in the registration and underwriting shall be allocated in the following manner: (a) first, shares of Company equity
securities that the Company desires to include in such registration shall be excluded and (b) second, Registrable
Securities requested to be included in such registration by the Investors shall be excluded. To facilitate the allocation of
shares in accordance with the above provisions, the Company or the underwriters may round down the number of shares allocated
to any of the Investors to the nearest 100 shares.

 

    

     

    

 

2.3.    Fees
and Expenses. All Registration Expenses incurred in connection with registrations pursuant to this Agreement shall be borne
by the Company. All Selling Expenses relating to securities registered on behalf of the Investors shall be borne by the Investors.

 

2.4.    Registration
Procedures. In the case of each registration of Registrable Securities effected by the Company pursuant to Section 2.1 hereof,
the Company shall keep the Investors advised as to the initiation of each such registration and as to the status thereof. The Company
shall use its reasonable best efforts, within the limits set forth in this Section 2.4, to:

 

(a)    prepare
and file with the Commission such amendments and supplements to such Registration Statement and the prospectuses used in connection
with such Registration Statement as may be necessary to keep such Registration Statement effective and current and comply with
the provisions of the Securities Act with respect to the disposition of all securities covered by such Registration Statement;

 

(b)    furnish
to the Investors such numbers of copies of a prospectus, including preliminary prospectuses, in conformity with the requirements
of the Securities Act, and such other documents as the Investors may reasonably request in order to facilitate the disposition
of Registrable Securities;

 

(c)    use
its reasonable best efforts to register and qualify the Registrable Securities covered by such Registration Statement under such
other securities or blue sky laws of such jurisdictions in the United States as shall be reasonably requested by the Investors,
provided that the Company shall not be required in connection therewith or as a condition thereto to qualify to do business or
to file a general consent to service of process in any such states or jurisdictions;

 

(d)    in
the event of any underwritten public offering, and subject to Section 2.2(d), enter into and perform its obligations
under an underwriting agreement, in usual and customary form, with the managing underwriter of such offering and take such other
usual and customary action as the Investors may reasonably request in order to facilitate the disposition of such Registrable Securities;

 

(e)    notify
the Investors at any time when a prospectus relating to a Registration Statement covering any Registrable Securities is
required to be delivered under the Securities Act of the happening of any event as a result of which the prospectus included
in such Registration Statement, as then in effect, includes an untrue statement of a material fact or omits to state a
material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the
circumstances then existing. The Company shall use its reasonable best efforts to amend or supplement such prospectus in
order to cause such prospectus not to include any untrue statement of a material fact or omit to state a material fact
required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances
then existing;

 

    

     

    

 

(f)    provide
a transfer agent and registrar for all Registrable Securities registered pursuant to such Registration Statement and, if required,
a CUSIP number for all such Registrable Securities, in each case not later than the effective date of such registration;

 

(g)    if
requested by an Investor, use reasonable best efforts to cause the Company’s transfer agent to remove any restrictive legend
from any Registrable Securities, within two business days following such request;

 

(h)    cause
to be furnished, at the request of the Investors, on the date that Registrable Securities are delivered to underwriters for sale
in connection with an underwritten offering pursuant to this Agreement, (i) an opinion, dated such date, of the counsel representing
the Company for the purposes of such registration, in form and substance as is customarily given to underwriters in an underwritten
public offering, addressed to the underwriters, and (ii) a letter or letters from the independent certified public accountants
of the Company, in form and substance as is customarily given by independent certified public accountants to underwriters in an
underwritten public offering, addressed to the underwriters; and

 

(i)     cause
all such Registrable Securities included in a Registration Statement pursuant to this Agreement to be listed on each securities
exchange or other securities trading markets on which Common Stock is then listed.

 

2.5.    The
Investors Obligations.

 

(a)    Discontinuance
of Distribution. The Investors agree that, upon receipt of any notice from the Company of the occurrence of any event of the
kind described in Section 2.4(e) hereof, the Investors shall immediately discontinue disposition of Registrable
Securities pursuant to any Registration Statement covering such Registrable Securities until the Investors’ receipt of the
copies of the supplemented or amended prospectus contemplated by Section 2.4(e) hereof or receipt of notice
that no supplement or amendment is required and that the Investors’ disposition of the Registrable Securities may be resumed.
The Company may provide appropriate stop orders to enforce the provisions of this Section 2.5(a).

 

(b)    Compliance
with Prospectus Delivery Requirements. The Investors covenant and agree that they shall comply with the prospectus delivery
requirements of the Securities Act as applicable to them or an exemption therefrom in connection with sales of Registrable Securities
pursuant to any Registration Statement filed by the Company pursuant to this Agreement.

 

(c)    Notification
of Sale of Registrable Securities. The Investors covenant and agree that they shall notify the Company following the sale of
Registrable Securities to a third party as promptly as reasonably practicable, and in any event within thirty (30) days, following
the sale of such Registrable Securities.

 

    

     

    

 

2.6.    Indemnification.

 

(a)    To
the extent permitted by law, the Company shall indemnify the Investors, and, as applicable, their officers, directors, and constituent
partners, legal counsel for each Investor and each Person controlling the Investors, with respect to which registration, related
qualification, or related compliance of Registrable Securities has been effected pursuant to this Agreement, and each underwriter,
if any, and each Person who controls any underwriter within the meaning of the Securities Act against all claims, losses, damages,
or liabilities (or actions in respect thereof) to the extent such claims, losses, damages, or liabilities arise out of or are based
upon (i) any untrue statement (or alleged untrue statement) of a material fact contained in any prospectus or other document
(including any related Registration Statement) incident to any such registration, qualification, or compliance, 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 not misleading, or (iii) any violation or alleged violation by the Company of the Securities Act, the Exchange Act,
any state securities law, or any rule or regulation promulgated under the Securities Act, the Exchange Act or any state securities
law applicable to the Company and relating to action or inaction required of the Company in connection with any such registration,
qualification, or compliance; and the Company shall pay as incurred to the Investors, each such underwriter, and each Person who
controls the Investors or underwriter, any legal and any other expenses reasonably incurred in connection with investigating or
defending any such claim, loss, damage, liability, or action; provided, however, that the indemnity contained
in this Section 2.6(a) shall not apply to amounts paid in settlement of any such claim, loss, damage, liability,
or action if settlement is effected without the consent of the Company (which consent shall not unreasonably be withheld); and
provided, further, that the Company shall not be liable in any such case to the extent that any such claim, loss, damage, liability,
or expense arises out of or is based upon any violation by such Investor of the obligations set forth in Section 2.5 hereof
or any untrue statement or omission contained in such prospectus or other document based upon written information furnished to
the Company by the Investors, such underwriter, or such controlling Person and stated to be for use therein.

 

(b)    To
the extent permitted by law, each Investor (severally and not jointly) shall, if Registrable Securities held by such Investor
are included for sale in the registration and related qualification and compliance effected pursuant to this Agreement, indemnify
the Company, each of its directors, each officer of the Company who signs the applicable Registration Statement, each legal counsel
and each underwriter of the Company’s securities covered by such a Registration Statement, each Person who controls the
Company or such underwriter within the meaning of the Securities Act against all claims, losses, damages, and liabilities (or
actions in respect thereof) arising out of or based upon (i) any untrue statement (or alleged untrue statement) of a material
fact contained in any such Registration Statement, or related document, 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 not misleading, or (iii) any
violation or alleged violation by such Investor of Section 2.5 hereof, the Securities Act, the Exchange
Act, any state securities law, or any rule or regulation promulgated under the Securities Act, the Exchange Act or any state securities
law applicable to such Investor and relating to action or inaction required of such Investor in connection with any such registration
and related qualification and compliance, and shall pay as incurred to such persons, any legal and any other expenses reasonably
incurred in connection with investigating or defending any such claim, loss,damage, liability, or action, in each case only to
the extent that such untrue statement (or alleged untrue statement) or omission (or alleged omission) is made in (and such violation
pertains to) such Registration Statement or related document in reliance upon and in conformity with written information furnished
to the Company by such Investor and stated to be specifically for use therein; provided, however, that
the indemnity contained in this Section 2.6(b) shall not apply to amounts paid in settlement of any such
claim, loss, damage, liability, or action if settlement is effected without the consent of such Investor (which consent shall
not unreasonably be withheld); provided, further, that such Investor’s liability under this Section 2.6(b) (when
combined with any amounts such Investor is liable for under Section 2.6(d)) shall not exceed such Investor’s
net proceeds from the offering of securities made in connection with such registration.

 

    

     

    

 

(c)    Promptly
after receipt by an indemnified party under this Section 2.6 of notice of the commencement of any action,
such indemnified party shall, if a claim in respect thereof is to be made against an indemnifying party under this Section 2.6,
notify the indemnifying party in writing of the commencement thereof and generally summarize such action. The indemnifying party
shall have the right to participate in and to assume the defense of such claim; provided, however, that
the indemnifying party shall be entitled to select counsel for the defense of such claim with the approval of any parties entitled
to indemnification, which approval shall not be unreasonably withheld; provided further, however, that if either party reasonably
determines that there may be a conflict between the position of the Company and the Investors in conducting the defense of such
action, suit, or proceeding by reason of recognized claims for indemnity under this Section 2.6, then counsel
for such party shall be entitled to conduct the defense to the extent reasonably determined by such counsel to be necessary to
protect the interest of such party. The failure to notify an indemnifying party promptly of the commencement of any such action,
if prejudicial to the ability of the indemnifying party to defend such action, shall relieve such indemnifying party, to the extent
so prejudiced, of any liability to the indemnified party under this Section 2.6, but the omission so to notify
the indemnifying party shall not relieve such party of any liability that such party may have to any indemnified party otherwise
than under this Section 2.6.

 

(d)    If
the indemnification provided for in this Section 2.6 is held by a court of competent jurisdiction to be
unavailable to an indemnified party with respect to any loss, liability, claim, damage, or expense referred to therein, then
the indemnifying party, in lieu of indemnifying such indemnified party hereunder, shall contribute to the amount paid or
payable by such indemnified party as a result of such loss, liability, claim, damage, or expense in such proportion as is
appropriate to reflect the relative fault of the indemnifying party on the one hand and of the indemnified party on the other
in connection with the statements or omissions that resulted in such loss, liability, claim, damage, or expense as well as
any other relevant equitable considerations. The relative fault of the indemnifying party and of the indemnified party shall
be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the
omission to state a material fact relates to information supplied by the indemnifying party or by the indemnified party and
the parties’ relative intent, knowledge, access to information, and opportunity to correct or prevent such statement or
omission. In no event, however, shall (i) any amount due for contribution hereunder be in excess of the amount that
would otherwise be due under Section 2.6(a) or Section 2.6(b), as applicable, based on
the limitations of such provisions and (ii) a Person guilty of fraudulent misrepresentation (within the meaning of the
Securities Act) be entitled to contribution from a Person who was not guilty of such fraudulent misrepresentation.

 

    

     

    

 

(e)    Notwithstanding
the foregoing, to the extent that the provisions on indemnification and contribution contained in the underwriting agreement entered
into in connection with an underwritten public offering are in conflict with the foregoing provisions, the provisions in the underwriting
agreement shall control; provided, however, that the failure of the underwriting agreement to provide for
or address a matter provided for or addressed by the foregoing provisions shall not be a conflict between the underwriting agreement
and the foregoing provisions.

 

(f)    The
obligations of the Company and the Investors under this Section 2.6 shall survive the completion of any offering
of Registrable Securities in a Registration Statement under this Agreement or otherwise.

 

2.7.    Information.
The Investors shall furnish to the Company such information regarding the Investors and the distribution proposed by the Investors
as the Company may reasonably request and as shall be reasonably required in connection with any registration referred to in this
Agreement. The Investors agree to, as promptly as practicable (and in any event prior to any sales made pursuant to a prospectus),
furnish to the Company all information required to be disclosed in order to make the information previously furnished to the Company
by the Investors not misleading. The Investors agree to keep confidential the receipt of any notice received pursuant to Section 2.4(e) and
the contents thereof, except as required pursuant to applicable law. Notwithstanding anything to the contrary herein, the Company
shall be under no obligation to name the Investors in any Registration Statement if the Investors have not provided the information
required by this Section 2.7 with respect to the Investors as a selling securityholder in such Registration
Statement or any related prospectus.

 

2.8.    Rule
144 Requirements. With a view to making available to the Investors the benefits of Rule 144 promulgated under the Securities
Act and any other rule or regulation of the Commission that may at any time permit the Investors to sell Registrable Securities
to the public without registration, the Company agrees to use its reasonable best efforts to:

 

(a)    make
and keep public information available, as those terms are understood and defined in Rule 144 under the Securities Act at all times
after the date hereof;

 

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

 

(c)    prior
to the filing of the Registration Statement or any amendment thereto (whether pre-effective or post-effective), and
prior to the filing of any prospectus or prospectus supplement related thereto, to provide the Investors with copies of all of
the pages thereof (if any) that reference the Investors; and

 

(d)    furnish
to any Investor, so long as the Investor owns any Registrable Securities, forthwith upon request (i) a written statement
by the Company that it has complied with the reporting requirements of Rule 144, (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 by an Investor in availing itself of any rule or regulation of the Commission
which permits an Investor to sell any such securities without registration.

 

    

     

    

 

Section 3.

Miscellaneous

 

3.1.    Amendment.
No amendment, alteration or modification of any of the provisions of this Agreement shall be binding unless made in writing and
signed by each of the Company and the Investors.

 

3.2.    Injunctive
Relief. It is hereby agreed and acknowledged that it shall be impossible to measure in money the damages that would be suffered
if the parties fail to comply with any of the obligations herein imposed on them and that in the event of any such failure, an
aggrieved Person shall be irreparably damaged and shall not have an adequate remedy at law. Any such Person shall, therefore, be
entitled (in addition to any other remedy to which it may be entitled in law or in equity) to injunctive relief, including, without
limitation, specific performance, to enforce such obligations, and if any action should be brought in equity to enforce any of
the provisions of this Agreement, none of the parties hereto shall raise the defense that there is an adequate remedy at law.

 

3.3.    Notices.

(b)    Each
of the Company and the Investors irrevocably and unconditionally submits, for itself and its property, to the nonexclusive jurisdiction
of the courts of the State of New York sitting in the Borough of Manhattan, New York and of the United States District Court of
the Southern District of New York, and any appellate court from any thereof, in any action or proceeding arising out of or relating

hereunder, without the prior consent of the Company. Any transfer or assignment made other than as provided in the first
sentence of this Section 3.5 shall be null and void. Subject to the foregoing and except as otherwise
provided herein, the provisions of this Agreement shall inure to the benefit of, and be binding upon, the successors,

hereunder, unless prior to the consummation thereof, the Other Entity assumes, by written instrument, the obligations under

SECURITIES PURCHASE
AGREEMENT

 

This Securities
Purchase Agreement (this “Agreement”) is made and entered into as of July 13, 2020 (the “Effective
Date”) by and among Idera Pharmaceuticals, Inc., a Delaware corporation (the “Company”),
and entities controlled by Pillar Invest Corporation, Cayman Islands limited partnerships, set forth on Schedule A hereto (each
a “Purchaser” and together the “Purchasers”). Certain terms used and not otherwise
defined in the text of this Agreement are defined in Section 11 hereof.

 

RECITALS

 

WHEREAS, the Company
and the Purchasers are executing and delivering this Agreement in reliance upon the exemption from securities registration afforded
by Section 4(a)(2) of the Securities Act of 1933, as amended (the “1933 Act”), and Rule 506 of Regulation
D promulgated by the United States Securities and Exchange Commission (the “Commission”) under the 1933
Act; and

 

WHEREAS, the Company
desires to sell to the Purchasers, and the Purchasers desire to purchase from the Company, (i) shares (“Shares”)
of the Company’s common stock, par value $0.001 per share (the “Common Stock”), (ii) pre-funded
warrants in the form attached hereto as Exhibit A-1 (the “Pre-Funded Warrants”) to purchase shares
of Common Stock solely in the event that the Purchasers determine, in its sole discretion, that the Purchasers (together with the
Purchasers’ Affiliates, and any Person acting as a group together with the Purchasers or any of the Purchasers’ Affiliates)
would beneficially own in excess of 19.99% of the number of shares of Common Stock outstanding immediately after giving effect
to the issuance of the Shares on the applicable Closing Date (the “Beneficial Ownership Limitation”)
and (iii) warrants in the form attached hereto as Exhibit A-2 (the “Common Warrants”
and, together with the Pre-Funded Warrants, the “Warrants”) to purchase shares of Common Stock.

 

NOW, THEREFORE,
in consideration of the foregoing and the mutual representations, warranties and covenants herein contained, the parties hereto
hereby agree as follows:

 

SECTION 1.     Authorization
of Securities.

 

1.01    The
Company has authorized the sale and issuance of the Shares and the Warrants on the terms and subject to the conditions set forth
in this Agreement. The Shares and the Warrants sold hereunder at each Closing shall be referred to as the “Securities.”

 

     

     

    

 

SECTION 2.    Sale
and Purchase of the Securities.

 

2.01   (a) First
Closing Securities. Upon the terms and subject to the conditions herein contained, the Company agrees to sell to the
Purchasers, and the Purchasers agree to purchase from the Company, for an aggregate purchase price of $5,100,000, (i) 749,993
Shares, (ii) 2,014,234 Pre-Funded Warrants, and (iii) Common Warrants accompanying the Shares which shall be exercisable for
2,764,227 Warrant Shares and shall have an exercise price of $2.58 per Warrant Share, subject to adjustment as provided in
the Common Warrants. The number of Warrant Shares exercisable from the Pre-Funded Warrants issued in the First Closing equals
to the difference of subtracting (A) the number of Shares purchased in the First Closing from (B) the number of shares of
Common Stock that would have been purchased by the Purchasers in the First Closing absent the Beneficial Ownership
Limitation, and shall have a nominal exercise price of $0.01 per Warrant Share, subject to adjustment as provided in the
Pre-Funded Warrants.

 

(b)    Second
Closing Securities. Upon the terms and subject to the conditions herein contained, the Company agrees to sell to the Purchasers,
and the Purchasers agree to purchase from the Company, for an aggregate purchase price of $5,100,000, (i) 784,615 Pre-Funded Warrants
and (ii) Common Warrants accompanying the Pre-Funded Warrants which shall be exercisable for 274,615 Warrant Shares (collectively,
the “Second Closing Securities”) and shall have an exercise price of $9.75 per Warrant Share, subject
to adjustment as provided in the Common Warrants. The number of Warrant Shares exercisable from the Pre-Funded Warrants issued
in the Second Closing equals to the number of shares of Common Stock that would have been purchased by the Purchasers in the Second
Closing absent the Beneficial Ownership Limitation, and shall have a nominal exercise price of $0.01 per Warrant Share, subject
to adjustment as provided in the Pre-Funded Warrants.

 

For the avoidance
of doubt, the aggregate exercise price for the Pre-Funded Warrants as provided in Sections 2.01(a) and 2.01(b) above, except for
the nominal exercise price of $0.01 per Warrant Share, shall be pre-funded to the Company (the “Pre-paid Aggregate
Exercise Price”) on or prior to the date of the applicable Closing and, consequently, no additional consideration
(other than the nominal exercise price of $0.01 per Warrant Share) shall be required to be paid by the Purchasers to effect any
exercise of a Pre-Funded Warrant. The Purchasers shall not be entitled to the return or refund of all, or any portion, of such
Pre-paid Aggregate Exercise Price under any circumstance or for any reason whatsoever.

 

2.02    At
or prior to each Closing, the Purchasers will pay the applicable purchase price set forth in Section 2.01 by wire transfer of immediately
available funds in accordance with wire instructions provided by the Company to the Purchasers prior to such Closing.

 

2.03    To
the extent that the Company does not receive payments of the First Closing purchase price from the Purchasers as set forth in Section
2.02 above within two (2) business days of the Effective Date, then (i) this Agreement shall be null and void with respect to any
and all covenants and obligations binding on the Company and (ii) the Purchasers shall reimburse the Company up to $50,000 for
the Company’s costs incurred in negotiating and executing this Agreement and other related transaction documents, in the
case of each of (i) and (ii) above, without prejudice to other remedies the Company may have at law or equity.

 

2.04       Uncertificated
Securities. The Securities and Warrant Shares issuable upon exercise of the Warrants will be uncertificated. In lieu of certificates,
such uncertificated shares of the Securities and Warrant Shares issuable upon exercise of the Warrants shall be credited to a book
entry account maintained by the Company (or its designee).

 

     

     

    

 

SECTION 3.     Closings.
Subject to the satisfaction of the closing conditions set forth in Section 7:

 

3.01 (a)    The
closing with respect to the transactions contemplated in Section 2.01(a) hereof (the “First Closing”)
shall occur upon the satisfaction of the closing conditions set forth in Section 7 (the “First Closing
Date”).

 

3.02 (b)    The

and, together with the First Closing, each a “Closing”) shall occur on or before the tenth Business Day
following the ORR Data Announcement (as defined below) and shall be held on or before the fifth day following delivery of written
notice by the Purchasers to the Company, including the allocation of the Second Closing Securities among the Purchasers, and upon

with the First Closing Date, each a “Closing Date”). For purposes of this agreement, “ORR

study protocol, as agreed with the FDA prior to unblinding (the “ORR Data”).

the federal securities laws inasmuch as they are being acquired from the Company in a private placement under Section 4(a)(2)

and performance of this Agreement and the consummation of the transactions contemplated herein (including the issuance and
sale of the Securities and Warrant Shares) and compliance by the Company with its obligations hereunder do not and will not,
whether with or without the giving of notice or passage of time or both, conflict with or constitute a breach of, or default
or Repayment Event (as defined below) under, or result in the creation or imposition of any lien, charge or encumbrance upon
any properties or assets of the Company or any subsidiary pursuant to, the Agreements and Instruments (except for such
conflicts, breaches, defaults or Repayment Events or liens, charges or encumbrances that would not, singly or in the
aggregate, result in a Material Adverse Effect), nor will such action result in any violation of (i) the provisions of
the Restated Certificate of Incorporation of the Company, as amended (the “Certificate of
Incorporation”), the Amended and Restated Bylaws of the Company (the
 “Bylaws”) or similar organizational document of the Company or any of its subsidiaries or
(ii) any applicable law, statute, rule, regulation, judgment, order, writ or decree of any Governmental Entity, and
except in the case of clause (ii) for such violations as would not, singly or in the aggregate, result in a Material
Adverse Effect. As used herein, a “Repayment Event” means any event or condition which gives the

right to require the repurchase, redemption or repayment of all or a portion of such indebtedness by the Company or any of
its subsidiaries.

Principal Trading Market, as may be required under state securities laws or the filings required pursuant to Section 6.03 of

5.14    Possession
of Licenses and Permits. The Company and its subsidiaries possess such permits, licenses, approvals, consents and other
authorizations (collectively, “Governmental Licenses”) issued by the appropriate Governmental
Entities necessary to conduct the business now operated by them, except where the failure so to possess would not, singly or
in the aggregate, result in a Material Adverse Effect. The Company and its subsidiaries are in compliance with the terms and
conditions of all Governmental Licenses, except where the failure so to comply would not, singly or in the aggregate, result
in a Material Adverse Effect. All of the Governmental Licenses are valid and in full force and effect, except when the
invalidity of such Governmental Licenses or the failure of such Governmental Licenses to be in full force and effect would
not, singly or in the aggregate, result in a Material Adverse Effect. Neither the Company nor any of its subsidiaries has
received any notice of proceedings relating to the revocation or modification of any Governmental Licenses which, singly or

of the Company and its subsidiaries, considered as one enterprise, and under which the Company or any of its subsidiaries holds
properties described in the SEC Reports, are in full force and effect, and neither the Company nor any such subsidiary has any
notice of any material claim of any sort that has been asserted by anyone adverse to the rights of the Company or any subsidiary
under any of the leases or subleases mentioned above, or affecting or questioning the rights of the Company or such subsidiary
to the continued possession of the leased or subleased premises under any such lease or sublease.

 

5.16    Intellectual
Property. The Company and its subsidiaries own or possess the right to use all patents, patent applications, inventions,
licenses, know-how (including trade secrets and other unpatented and/or unpatentable proprietary or confidential

property, and registrations and applications for registration of any of the foregoing (collectively,
 “Intellectual Property”) necessary to conduct their business as presently conducted and currently
contemplated to be conducted in the future as described in the SEC Reports and, to the knowledge of the Company, neither the
Company nor any of its subsidiaries, whether through their respective products and services or the conduct of their
respective businesses, has infringed, misappropriated, conflicted with or otherwise violated, or is currently infringing,
misappropriating, conflicting with or otherwise violating, and none of the Company or its subsidiaries have received any
heretofore unresolved communication or notice of infringement of, misappropriation of, conflict with or violation of, any

of its subsidiaries has received any communication or notice (in each case that has not been resolved) alleging that by
conducting their business as described in the SEC Reports, such parties would infringe, misappropriate, conflict with, or
violate, any of the Intellectual Property of any other person or entity. The Company knows of no infringement,
misappropriation or violation by others of Intellectual Property owned by or licensed to the Company or its subsidiaries
which would reasonably be expected to result in a Material Adverse Effect. The Company and its subsidiaries have taken all
reasonable steps necessary to secure their interests in such Intellectual Property from their employees and contractors and
to protect the confidentiality of all of their confidential information and trade secrets. None of the Intellectual Property
employed by the Company or its subsidiaries has been obtained or is being used by the Company or its subsidiaries in
violation of any contractual obligation binding on the Company or any of its subsidiaries or, to the knowledge of the
Company, any of their respective officers, directors or employees, except as would not reasonably be expected, individually
or in the aggregate, to have a Material Adverse Effect. All Intellectual Property owned or exclusively licensed by the
Company or its subsidiaries is free and clear of all liens, encumbrances, defects or other restrictions (other
than non-exclusive licenses granted in the ordinary course of business), except those that would not reasonably be
expected, individually or in the aggregate, to have a Material Adverse Effect. The Company and its subsidiaries are not
subject to any judgment, order, writ, injunction or decree of any court or any Governmental Entity, nor has the Company or
any of its subsidiaries entered into or become a party to any agreement made in settlement of any pending or threatened
litigation, which materially restricts or impairs their use of any Intellectual Property.

Environmental Laws.

 

     

     

    

 

5.20    Accounting
Controls and Disclosure Controls. The Company and its subsidiaries maintain effective internal control over financial reporting

has materially adversely affected, or is reasonably likely to materially adversely affect, the Company’s internal control
over financial reporting.

No assessment in connection with United States federal tax returns has been made against the Company. The Company and its

taxes due and payable pursuant to any assessment received by the Company and its subsidiaries, except for such taxes, if any,
as are being contested in good faith and as to which adequate reserves have been established by the Company or its
subsidiaries and except where the failure to pay such taxes would not result in a Material Adverse Effect. The charges,
accruals and reserves on the books of the Company in respect of any income and corporation tax liability for any years not

determined, except to the extent of any inadequacy that would not result in a Material Adverse Effect.

 “IRS”) upon which it can rely, and any such determination or opinion letter remains in effect and has
not been revoked and no event has occurred and no facts or circumstances exist that could reasonably be expected to result in the
loss of qualification or tax exemption of any such Employee Benefit Plan. With respect to each Foreign Benefit Plan, such Foreign
Benefit Plan (1) if intended to qualify for special tax treatment, meets, in all material respects, the requirements for such

believes to be financially sound and reputable insurers, in such amounts and covering such risks as is adequate for the

full force and effect. The Company has no reason to believe that it or any of the Subsidiaries will not be able (A) to
renew its existing insurance coverage as and when such policies expire or (B) to obtain comparable coverage from similar
