securities to any Person (other than the Purchasers) and will not result in a right of any holder of Company securities to adjust the exercise, conversion, exchange or reset price under any of such securities. There are no stockholders agreements,
voting agreements or other agreements with respect to the Company’s capital stock to which the Company is a party or, to the knowledge of the Company, between or among any of the Company’s stockholders.

 12 

 (p) No Conflicts. Neither the execution of this Agreement, nor the issuance, offering or
sale of the Securities, nor the consummation of any of the transactions contemplated in the Transaction Documents, nor the compliance by the Company with the terms and provisions of the Transaction Documents will conflict with, or will result in a
breach of, any of the terms and provisions of, or has constituted or will constitute a default under, or has resulted in or will result in the creation or imposition of any lien, charge or encumbrance upon any property or assets of the Company
pursuant to the terms of any contract or other agreement to which the Company may be bound or to which any of the property or assets of the Company is subject, except (i) such conflicts, breaches or defaults as may have been waived and
(ii) such conflicts, breaches and defaults that would not reasonably be expected to have a Material Adverse Effect; nor will such action result (x) in any violation of the provisions of the organizational or governing documents of the
Company, or (y) in any violation of the provisions of any statute or any order, rule or regulation applicable to the Company or of any court or of any federal, state or other regulatory authority or other government body having jurisdiction
over the Company, except where such violation would not reasonably be expected to have a Material Adverse Effect. 
 (q) No Material
Defaults. Neither the Company nor any Subsidiary has defaulted on any installment on indebtedness for borrowed money or on any rental on one or more long-term leases, which defaults, individually or in the aggregate, could reasonably be expected
to have a Material Adverse Effect. The Company has not filed a report pursuant to Section 13(a) or 15(d) of the Exchange Act since the filing of its last Annual Report on Form 10-K, indicating that it
(i) has failed to pay any dividend or sinking fund installment on preferred stock or (ii) has defaulted on any installment on indebtedness for borrowed money or on any rental on one or more long-term leases, which defaults, individually or
in the aggregate, would reasonably be expected to have a Material Adverse Effect. 
 (r) Enforceability of Agreements. To the
knowledge of the Company, all agreements between the Company and third parties expressly referenced in the Disclosure Materials, other than such agreements that have expired by their terms or whose termination is disclosed in Disclosure Materials,
are legal, valid and binding obligations of the Company enforceable in accordance with their respective terms, except to the extent that (i) enforceability may be limited by bankruptcy, insolvency, reorganization, moratorium or similar laws
affecting creditors’ rights generally and by general equitable principles and (ii) the indemnification provisions of certain agreements may be limited by federal or state securities laws or public policy considerations in respect thereof,
and except for any unenforceability that, individually or in the aggregate, would not unreasonably be expected to have a Material Adverse Effect. 

(s) No Litigation. There are no legal, governmental or regulatory Proceedings pending, nor, to the Company’s knowledge, any legal,
governmental or regulatory investigations, to which the Company or a Subsidiary is a party or to which any property of the Company or any Subsidiary is the subject that, individually or in the aggregate, would reasonably be expected to have a
Material Adverse Effect or materially and adversely affect the ability of the Company to perform its obligations under the Transaction Agreements; to the Company’s knowledge, no such actions, suits or Proceedings are threatened or contemplated
by any governmental or regulatory authority or threatened by others that, individually or in the aggregate, would reasonably be expected to have a Material Adverse Effect, except as disclosed in the SEC Reports; and (i) there are no current or
pending legal, governmental or regulatory investigations, actions, suits or Proceedings that are required under the Securities Act to be described in the Disclosure Materials that are not described in the Disclosure Materials; and (ii) there
are no contracts or other documents that are required under the Securities Act or Exchange Act to be filed as exhibits to the SEC Reports that are not so filed. 

(t) Licenses and Permits. The Company and the Subsidiaries possess or have obtained, all licenses, certificates, consents, orders,
approvals, permits and other authorizations issued by, and have made all declarations and filings with, the appropriate federal, state, local or foreign governmental or regulatory authorities that are necessary for the ownership or lease of their
respective 

  
 13 

 
properties or the conduct of their respective businesses as described in the SEC Reports (the “Permits”), except where the failure to possess, obtain or make the same would not,
individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. Neither the Company nor any Subsidiary have received written notice of any Proceeding relating to revocation or modification of any such Permit or has any
reason to believe that such Permit will not be renewed in the ordinary course, except where the failure to obtain any such renewal would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. 

(u) Compliance with Applicable Laws. The Company and the Subsidiaries: (i) are in compliance with all statutes, rules and
regulations applicable to the testing, development, manufacture, packaging, processing, use, distribution, marketing, labeling, promotion, sale, offer for sale, storage, import, export or disposal of any product under development, manufactured or
distributed by the Company or the Subsidiaries (“Applicable Laws”), except where such noncompliance would not reasonably be expected to have a Material Adverse Effect, (ii) have not received any Form 483 from the FDA, notice of
adverse finding, warning letter, or other written correspondence or notice from the FDA, the EMA, or any other federal, state, local or foreign governmental or regulatory authority alleging or asserting material noncompliance with any Applicable
Laws or any licenses, certificates, approvals, clearances, authorizations, permits and supplements or amendments thereto required by any such Applicable Laws (“Authorizations”), that would, individually or in the aggregate, result
in a Material Adverse Effect; (iii) possess all material Authorizations and such Authorizations are valid and in full force and effect and neither the Company nor the Subsidiaries is in violation of any term of any such Authorizations except

arbitration or other action from the FDA, the EMA, or any other federal, state, local or foreign governmental or regulatory authority or third party alleging that any Company product, operation or activity is in violation of any Applicable Laws or
Authorizations which noncompliance would reasonably be expected to have a Material Adverse Effect and has no knowledge that the FDA, the EMA, or any other federal, state, local or foreign governmental or regulatory authority or third party is
considering any such claim, litigation, arbitration, action, suit, investigation or Proceeding against the Company; (v) have not received written notice that the FDA, EMA, or any other federal, state, local or foreign governmental or regulatory

federal, state, local or foreign governmental or regulatory authority is considering such action; and (vi) have filed, obtained, maintained or submitted all reports, documents, forms, notices, applications, records, claims, submissions and
supplements or amendments as required by any Applicable Laws or Authorizations except where the failure to file, obtain, maintain or submit such reports, documents, forms, notices, applications, records, claims, submissions and supplements or
amendments would not result in a Material Adverse Effect, and that all such reports, documents, forms, notices, applications, records, claims, submissions and supplements or amendments were materially complete and correct on the date filed (or were
corrected or supplemented by a subsequent submission) except such incompletions and incorrections as would not reasonably be expected to result in a Material Adverse Effect. 

(v) Title to Real and Personal Property. The Company and the Subsidiaries have good and valid title in fee simple to all items of real
property and good and valid title to all personal property described in the SEC Reports as being owned by them that are material to the businesses of the Company or such Subsidiary, in each case free and clear of all liens, encumbrances and claims,
except those that (i) do not materially interfere with the use made and proposed to be made of such property by the Company and the Subsidiaries or (ii) would not reasonably be expected, individually or in the aggregate, to have a Material
Adverse Effect. To the knowledge of the Company, any real property described in the SEC Reports as being leased by the Company and the Subsidiaries is held by them under 

  
 14 

 
valid, existing and enforceable leases, except those that (A) do not materially interfere with the use made or proposed to be made of such property by the Company or the Subsidiaries or
(B) would not be reasonably expected, individually or in the aggregate, to have a Material Adverse Effect. 
 (w) Intellectual
Property. The Company and the Subsidiaries own or possess adequate enforceable rights to use all patents, patent applications, trademarks (both registered and unregistered), service marks, trade names, trademark registrations, service mark
registrations, copyrights, licenses and know-how (including trade secrets and other unpatented and/or unpatentable proprietary or confidential information, systems or procedures) (collectively, the
“Intellectual Property”), necessary for the conduct of their respective businesses as conducted as of the date hereof, except to the extent that the failure to own or possess adequate rights to use such Intellectual Property would
not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect; the Company and the Subsidiaries have not received any written notice of any claim of infringement or conflict that asserted Intellectual Property
rights of others, which infringement or conflict would reasonably be expected to result in a Material Adverse Effect; there are no pending, or to the knowledge of the Company, threatened judicial Proceedings or interference proceedings against the
Company or its Subsidiaries challenging the Company’s or any of its Subsidiary’s rights in or to or the validity of the scope of any of the Company’s or any Subsidiary’s patents, patent applications or proprietary information; to
the knowledge of the Company, no other entity or individual has any right or claim in any of the Company’s or any of its Subsidiary’s patents, patent applications or any patent to be issued therefrom by virtue of any contract, license or
other agreement entered into between such entity or individual and the Company or any Subsidiary or by any non-contractual obligation, other than by written licenses granted by the Company or any Subsidiary;
the Company and the Subsidiaries have not received any written notice of any claim challenging the rights of the Company or its Subsidiaries in or to any Intellectual Property owned, licensed or optioned by the Company or any Subsidiary which claim
would reasonably be expected to result in a Material Adverse Effect. 
 (x) Environmental Laws. The Company and the Subsidiaries
(i) are in compliance with any and all applicable federal, state, local and foreign laws, rules, regulations, decisions and orders relating to the protection of human health and safety, the environment or hazardous or toxic substances or
wastes, pollutants or contaminants (collectively, “Environmental Laws”); (ii) have received and are in compliance with all permits, licenses or other approvals required of them under applicable Environmental Laws to conduct their
respective businesses as described in the SEC Reports; and (iii) have not received notice of any actual or potential liability for the investigation or remediation of any disposal or release of hazardous or toxic substances or wastes,
pollutants or contaminants, except, in the case of any of clauses (i), (ii) or (iii) above, for any such failure to comply or failure to receive required permits, licenses, other approvals or liability as would not, individually or in the
aggregate, reasonably be expected to have a Material Adverse Effect. 
 (y) Insurance. The Company and the Subsidiaries carry,
or are covered by, insurance in such amounts and covering such risks as the Company and the Subsidiaries reasonably believe are adequate for the conduct of their business and as is customary for companies of similar size engaged in similar
businesses in similar industries. The Company has no reason to believe that it or any of its Subsidiaries will not be able (i) to renew its existing insurance coverage as and when such policies expire or (ii) to obtain comparable coverage
from similar institutions as may be necessary or appropriate to conduct its business as now conducted and at a cost that would not result in a Material Adverse Effect. Neither of the Company nor any of its Subsidiaries has been denied any insurance
coverage which it has sought or for which it has applied. 

  
 15 

 (z) Sarbanes-Oxley Act. There is and has been no failure on the part of the Company or, to
the knowledge of the Company, any of the Company’s directors or officers, in their capacities as such, to comply with any applicable provisions of the Sarbanes-Oxley Act and the rules and regulations promulgated thereunder. Each of the
principal executive officer and the principal financial officer of the Company (or each former principal executive officer of the Company and each former principal financial officer of the Company as applicable) has made all certifications required
by Sections 302 and 906 of the Sarbanes-Oxley Act with respect to all reports, schedules, forms, statements and other documents required to be filed by it or furnished by it to the Commission during the past 12 months. For purposes of the preceding
sentence, “principal executive officer” and “principal financial officer” shall have the meanings given to such terms in the Exchange Act Rules 13a-15 and
15d-15. 
 (aa) Disclosure Controls. The Company maintains systems of internal
accounting controls designed to provide reasonable assurance that (i) transactions are executed in accordance with management’s general or specific authorizations; (ii) transactions are recorded as necessary to permit preparation of
financial statements in conformity with GAAP and to maintain asset accountability; (iii) access to assets is permitted only in accordance with management’s general or specific authorization; and (iv) the recorded accountability for
assets is compared with the existing assets at reasonable intervals and appropriate action is taken with respect to any differences. The Company is not aware of any material weaknesses in its internal control over financial reporting. Since the date
of the latest audited financial statements of the Company included in its Annual Report on Form 10-K, there has been no change in the Company’s internal control over financial reporting that has
materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting. The Company has established disclosure controls and procedures (as defined in Exchange Act Rules 13a-15 and 15d-15) for the Company and designed such disclosure controls and procedures to ensure that material information relating to the Company and the Subsidiaries is
made known to the certifying officers by others within those entities, particularly during the period in which the Company’s Annual Report on Form 10-K or Quarterly Report on Form 10-Q, as the case may be, is being prepared. The Company’s certifying officers have evaluated the effectiveness of the Company’s controls and procedures as of a date within 90 days prior to the filing date
of the Form 10-K for the fiscal year most recently ended (such date, the “Evaluation Date”). The Company presented in its Form 10-K for the fiscal year
most recently ended the conclusions of the certifying officers about the effectiveness of the disclosure controls and procedures based on their evaluations as of the most recent Evaluation Date. Since the most recent Evaluation Date, there have been
no significant changes in the Company’s internal controls (as such term is defined in Item 307(b) of Regulation S-K under the Securities Act) or, to the Company’s knowledge, in other factors that
could significantly affect the Company’s internal controls. The Company’s “internal controls over financial reporting” and “disclosure controls and procedures” are effective. 

(bb) Off-Balance Sheet Arrangements. There are no transactions, arrangements and other
relationships between and/or among the Company, and/or, to the knowledge of the Company, any of its Affiliates and any unconsolidated entity, including, but not limited to, any structured finance, special purpose or limited purpose entity (each, an
“Off Balance Sheet Transaction”) that could reasonably be expected to affect materially the Company’s liquidity or the availability of or requirements for its capital resources, including those Off Balance Sheet Transactions
described in the Commission’s Statement about Management’s Discussion and Analysis of Financial Conditions and Results of Operations (Release Nos. 33-8056;
34-45321; FR-61), required to be described in the SEC Reports which have not been described as required.

(cc) Labor Disputes. No labor disturbance by or dispute with employees of the Company or any Subsidiary exists or, to the knowledge of
the Company, is threatened that would reasonably be expected to result in a Material Adverse Effect. 

  
 16 

 (dd) ERISA. To the knowledge of the Company, each material employee benefit plan, within
the meaning of Section 3(3) of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”), that is maintained, administered or contributed to by the Company or any of its Affiliates for employees or former
employees of the Company and the Subsidiaries has been maintained in material compliance with its terms and the requirements of any applicable statutes, orders, rules and regulations, including but not limited to ERISA and the Internal Revenue Code
of 1986, as amended (the “Code”); no prohibited transaction, within the meaning of Section 406 of ERISA or Section 4975 of the Code, has occurred which would result in a material liability to the Company with respect to
any such plan excluding transactions effected pursuant to a statutory or administrative exemption; and for each such plan that is subject to the funding rules of Section 412 of the Code or Section 302 of ERISA, no “accumulated funding
deficiency” as defined in Section 412 of the Code has been incurred, whether or not waived, and the fair market value of the assets of each such plan (excluding for these purposes accrued but unpaid contributions) exceeds the present value
of all benefits accrued under such plan determined using reasonable actuarial assumptions. 
 (ee) Forward-Looking Statements. No
forward-looking statement (within the meaning of Section 27A of the Securities Act and Section 21E of the Exchange Act) (a “Forward-Looking Statement”) contained in the SEC Reports has been made or reaffirmed without a
reasonable basis or has been disclosed other than in good faith. The Forward-Looking Statements made in the Company’s Annual Report on Form 10-K for the fiscal year most recently ended (i) except for
any Forward-Looking Statement included in any financial statements and notes thereto, are within the coverage of the safe harbor for forward looking statements set forth in Section 27A of the Securities Act, Rule 175(b) under the Securities Act
or Rule 3b-6 under the Exchange Act, as applicable, (ii) were made by the Company with a reasonable basis and in good faith and reflect the Company’s good faith commercially reasonable best estimate
of the matters described therein as of the respective dates on which such statements were made, and (iii) have been prepared in accordance with Item 10 of Regulation S-K under the Securities Act. 

(ff) Margin Rules. Neither the issuance, sale and delivery of the Securities nor the application of the proceeds thereof by the Company
will violate Regulation T, U or X of the Board of Governors of the Federal Reserve System. 
 (gg) Broker/Dealer Relationships.
Neither the Company nor any Subsidiary or any related entities (i) is required to register as a “broker” or “dealer” in accordance with the provisions of the Exchange Act or (ii) directly or indirectly through one or
more intermediaries, controls or is a “person associated with a member” or “associated person of a member” (within the meaning set forth in the FINRA Manual). 

(hh) Fees. No Person will have, as a result of the transactions contemplated by this Agreement, any valid right, interest or claim
against or upon the Company for any commission, fee or other compensation pursuant to any agreement, arrangement or understanding entered into by or on behalf of the Company with respect to the offer and sale of the Securities. 

(ii) Investment Company. Neither the Company nor any Subsidiary is or, after giving effect to the offering and sale of the
Securities pursuant to this Agreement and the Common Shares pursuant to the Initial Securities Purchase Agreement, will be an “investment company” or an entity “controlled” by an “investment company,” as such terms are
defined in the Investment Company Act of 1940, as amended. 
 (jj) Taxes. The Company and the Subsidiaries have filed all federal,
state, local and foreign tax returns that have been required to be filed and paid all taxes shown thereon through the date hereof, to the extent that such taxes have become due and are not being contested in good faith, except where the failure to
do so would not reasonably be expected to have a Material Adverse Effect. No tax deficiency has been determined adversely to the Company or any Subsidiary which has had, or would 

  
 17 

 
reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect. The Company has no knowledge of any federal, state or other governmental tax deficiency, penalty or
assessment which has been or might be asserted or threatened against it which could have a Material Adverse Effect. 
 (kk) No Improper
Practices. (i) Neither the Company nor the Subsidiaries, nor to the Company’s knowledge, any of their respective executive officers has, in the past five years, made any unlawful contributions to any candidate for any political office
(or failed fully to disclose any contribution in violation of law) or made any contribution or other payment to any official of, or candidate for, any federal, state, municipal, or foreign office or other Person charged with similar public or
quasi-public duty in violation of any law or of the character required to be disclosed in the SEC Reports; (ii) no relationship, direct or indirect, exists between or among the Company or, to the Company’s knowledge, the Subsidiaries or
any Affiliate of any of them, on the one hand, and the directors, officers and stockholders of the Company or, to the Company’s knowledge, the Subsidiaries, on the other hand, that is required by the Securities Act to be described in the SEC
Reports that is not so described; (iii) there are no material outstanding loans or advances or material guarantees of indebtedness by the Company or, to the Company’s knowledge, the Subsidiaries to or for the benefit of any of their
respective officers or directors or any of the members of the families of any of them; (iv) the Company has not offered, or caused any placement agent to offer, Common Shares to any Person with the intent to influence unlawfully (A) a
customer or supplier of the Company or the Subsidiaries to alter the customer’s or supplier’s level or type of business with the Company or the Subsidiaries or (B) a trade journalist or publication to write or publish favorable
information about the Company or the Subsidiaries or any of their respective products or services, and, (v) neither the Company nor the Subsidiaries nor, to the Company’s knowledge, any employee or agent of the Company or the Subsidiaries
has made any payment of funds of the Company or the Subsidiaries or received or retained any funds in violation of any law, rule or regulation (including, without limitation, the Foreign Corrupt Practices Act of 1977), which payment, receipt or
retention of funds is of a character required to be disclosed in the SEC Reports. 
 (ll) Operations. The operations of the Company
and the Subsidiaries are and have been conducted at all times in compliance with applicable financial record keeping and reporting requirements of the Currency and Foreign Transactions Reporting Act of 1970, as amended, the money laundering statutes
of all jurisdictions to which the Company or the Subsidiaries are subject, the rules and regulations thereunder and any related or similar rules, regulations or guidelines, issued, administered or enforced by any governmental agency (collectively,
the “Money Laundering Laws”), except as would not reasonably be expected to result in a Material Adverse Effect; and no action, suit or Proceeding by or before any court or governmental agency, authority or body or any arbitrator
involving the Company or any Subsidiary with respect to the Money Laundering Laws is pending or, to the knowledge of the Company, threatened. 

(mm) OFAC. Neither the Company nor any of its Subsidiaries nor, to the knowledge of the Company, any director, officer, agent,
employee, Affiliate or Person acting on behalf of the Company or any of its Subsidiaries is currently subject to any U.S. sanctions administered by the Office of Foreign Assets Control of the U.S. Treasury Department (“OFAC”); and
the Company will not directly or indirectly use the proceeds of this offering, or lend, contribute or otherwise make available such proceeds to any of its subsidiaries or any joint venture partner or other Person or entity, for the purpose of
financing the activities of any Person currently subject to any U.S. sanctions administered by OFAC. 
 (nn) U.S. Real Property Holdings
Corporation. The Company is not and has never been a U.S. real property holding corporation, within the meaning of Section 897 of the Internal Revenue Code of 1986, as amended, and the Company shall so certify upon Purchaser’s request.

  
 18 

 (oo) Compliance Program. The Company has established and administers a compliance program
applicable to the Company, to assist the Company and the directors, officers and employees of the Company in complying with applicable regulatory guidelines (including, without limitation, those administered by the FDA, the EMA, and any other
foreign, federal, state or local governmental or regulatory authority performing functions similar to those performed by the FDA or EMA); except where such noncompliance would not reasonably be expected to have a Material Adverse Effect. 

(pp) Clinical Studies. All animal and other preclinical studies and clinical trials currently being conducted by the Company or on
behalf of the Company are, to the Company’s knowledge, being conducted in all material respects in compliance with all Applicable Laws and in accordance with experimental protocols, procedures and controls generally used by qualified experts in
the preclinical study and clinical trials of new drugs and biologics as applied to comparable products to those being developed by the Company, and to the Company’s knowledge there are no other clinical trials or preclinical studies, the
results of which reasonably call into question the clinical trial or preclinical study results described or referred to in the SEC Reports when viewed in the context in which such results are described, except such results as would not reasonably be
expected to result in a Material Adverse Effect; and the Company has not received any written notices or correspondence from the FDA, the EMA, or any other domestic or foreign governmental agency requiring the termination or suspension of any
preclinical studies or clinical trials conducted by or on behalf of the Company that are described in the SEC Reports or the results of which are referred to in the SEC Reports. 

(qq) No General Solicitation. Neither the Company nor any Person acting on behalf of the Company has offered or sold any of the
Securities by any form of general solicitation or general advertising as such terms are defined in Regulation D. 
 (rr) Compliance with
Rule 506. None of the Company, any of its predecessors, any affiliated issuer, any director, executive officer, other officer of the Company participating in the offering contemplated hereby, any beneficial owner of 20% or more of the
Company’s outstanding voting equity securities, calculated on the basis of voting power, nor any promoter (as that term is defined in Rule 405 under the Securities Act) connected with the Company in any capacity at the time of sale is
disqualified from relying on Rule 506 for any of the reasons stated in Rule 506(d) in connection with the issuance and sale of the Securities to the Purchasers pursuant to this Agreement. The Company has exercised reasonable care, including without
limitation, conducting a factual inquiry that is appropriate in light of the circumstances, into whether any such disqualification under Rule 506(d) exists, but has assumed the accuracy of the Purchasers’ representations and warranties. The
Company has furnished to each Purchaser, a reasonable time prior to the date hereof, a description in writing of any matters that would have triggered disqualification under Rule 506(d), in compliance with the disclosure requirements of Rule 506(e).
The Company has exercised reasonable care, including without limitation, conducting a factual inquiry that is appropriate in light of the circumstances, into whether any such disqualification under Rule 506(d) would have existed and whether any
disclosure is required to be made to the Purchasers under Rule 506(e). Any outstanding securities of the Company (of any kind or nature) that were issued in reliance on Rule 506 have been issued in compliance with Rule 506(d) and (e) and no
party has any reasonable basis for challenging any such reliance on Rule 506 in connection therewith. 
 (ss) Private Placement.
Assuming the accuracy of the Purchasers’ representations and warranties set forth in Section 3.2, no registration under the Securities Act is required for the offer and sale of the Securities by the Company to the
Purchasers as contemplated hereby. The issuance and sale of the Securities hereunder does not contravene the rules and regulations of the Principal Trading Market or the ASX. 

  
 19 

 (tt) Certain Market Activities. Neither the Company, nor any Subsidiary, nor any of their
respective directors, officers or controlling Persons has taken, directly or indirectly, any action designed, or that has constituted or would reasonably be expected to cause or result in, under the Exchange Act or otherwise, the stabilization or
manipulation of the price of any security of the Company to facilitate the sale or resale of the Securities. 
 (uu) Application of
Takeover Protections. The Company and its Board of Directors have taken all necessary action, if any, in order to render inapplicable any control share acquisition, business combination, poison pill (including any distribution under a rights
agreement) or other similar anti-takeover provision under the Company’s certificate or articles of incorporation, or federal or state law that is or could become applicable to the Purchasers as a result of the Purchasers and the Company
fulfilling their obligations or exercising their rights under this Agreement, including without limitation as a result of the Company’s issuance of the Securities and the Purchasers’ ownership of the Securities. The execution, delivery and
performance by the Company of the Transaction Agreements, and the issuance and sale by the Company of the Securities as contemplated hereby will not result in a change of control or the acceleration of any vesting or other rights or obligations
under any agreement, contract, commitment, understanding or other arrangement between the Company or any Subsidiary and any other Person (including any benefit plans), other than as may have been waived pursuant to the Change of Control Waivers.

 (vv) Listing and Maintenance Requirements. The Common Shares were registered pursuant to Section 12(b) or 12(g) of the
Exchange Act, and the Company has taken no action designed to, or which to the knowledge of the Company, is likely to have the effect of, terminating the registration of the Common Shares under the Exchange Act nor has the Company received any
notification that the Commission is contemplating terminating such registration. The Company has not received notice from the Principal Trading Market to the effect that the Company is not in compliance with the listing or maintenance requirements
of the Principal Trading Market. The Company is, and has no reason to believe that it will not upon issuance of the Securities and for the foreseeable future continue to be, in compliance with all such listing and maintenance requirements. Subject
to the receipt of Stockholder Approval, the issuance of the Securities hereunder does not contravene the rules of the Principal Trading Market or the ASX. 

(ww) Use of Proceeds. The Company shall use the proceeds from the sale of the Securities for working capital purposes and to fund the
launch of the Company’s product candidates and products, including, but not limited to, any product candidates and products acquired in the Icon Acquisition.

ARTICLE IV 
 OTHER AGREEMENTS OF
THE PARTIES 
 4.1 Transfer Restrictions. 

(a) Compliance with Laws. Except as specifically provided for elsewhere in this Article IV, each
Purchaser covenants that the Securities may be disposed of only pursuant to an effective registration statement under, and in compliance with the requirements of, the Securities Act, or pursuant to an available exemption from, or in a transaction
not subject to, the registration requirements of the Securities Act, and in compliance with any applicable state and federal securities laws. In connection with any transfer of the Securities other than (i) pursuant to an effective
registration statement, (ii) to the Company, (iii) pursuant to Rule 144 (provided that the Purchaser provides the Company with reasonable assurances (in the form of seller and, if applicable, broker representation letters) that
the securities may be sold pursuant to such rule) or (iv) in connection with a bona fide pledge as contemplated in Section 4.1(b), the Company may require the transferor thereof to provide to the Company an opinion of
counsel selected by the transferor and reasonably acceptable to the Company, the form and substance of which opinion shall be reasonably satisfactory to the Company and the Transfer Agent, to the effect that such transfer does not require
registration of such transferred Securities under the Securities Act.

  
 22 

 (b) Legends. Certificates evidencing the Securities shall bear any legend as required
by the “blue sky” laws of any state and a restrictive legend in substantially the following form, until such time as they are not required under Section 4.1(c): 

THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR APPLICABLE STATE
SECURITIES LAWS. THE SECURITIES MAY NOT BE OFFERED FOR SALE, SOLD, OR OTHERWISE TRANSFERRED OR ASSIGNED (I) IN THE ABSENCE OF (A) AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES UNDER THE SECURITIES ACT OR (B) AN
AVAILABLE EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND IN ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS OR BLUE SKY LAWS AS EVIDENCED BY A LEGAL OPINION OF COUNSEL REASONABLY
SATISFACTORY TO THE COMPANY AND ITS TRANSFER AGENT OR (II) UNLESS SOLD PURSUANT TO RULE 144 UNDER THE SECURITIES ACT. NOTWITHSTANDING THE FOREGOING, THE SECURITIES MAY BE PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT OR OTHER
LOAN OR FINANCING ARRANGEMENT SECURED BY THE SECURITIES. 
 The Company acknowledges and agrees that a Purchaser may from time to time
pledge, and/or grant a security interest in, some or all of the legended Securities in connection with applicable securities laws, pursuant to a bona fide margin agreement in compliance with a bona fide margin loan. 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, but such legal opinion shall be required in connection with a subsequent
transfer or foreclosure following default by the Purchaser transferee of the pledge. No notice shall be required of such pledge, but Purchaser’s transferee shall promptly notify the Company of any such subsequent transfer or
foreclosure. Each Purchaser acknowledges that the Company shall not be responsible for any pledges relating to, or the grant of any security interest in, any of the Securities or for any agreement, understanding or arrangement between any
Purchaser and its pledgee or secured party. At the applicable Purchaser’s expense, the Company will execute and deliver such reasonable documentation as a pledgee or secured party of Securities may reasonably request in connection with a
pledge or transfer of the Securities, including the preparation and filing of any required prospectus supplement under Rule 424(b)(3) of the Securities Act or other applicable provision of the Securities Act to appropriately amend the list
of selling stockholders thereunder. Each Purchaser acknowledges and agrees that, except as otherwise provided in Section 4.1(c), any Securities subject to a pledge or security interest as contemplated by this
Section 4.1(b) shall continue to bear the legend set forth in this Section 4.1(b) and be subject to the restrictions on transfer set forth in Section 4.1(a).
Notwithstanding any provision in this Agreement to the contrary, each Purchaser shall comply with the Company’s Securities Trading Policy to the extent that such policy is applicable to such Purchaser by its terms with respect to the
prohibition under such policy on holding any securities of the Company in a margin account or otherwise pledging securities of the Company as collateral for a loan during any period of time that a Purchaser Designee is a member of the Board of
Directors. 
 (c) Removal of Legends.

(i) The legend set forth in Section 4.1(b) above shall be removed and the Company shall issue a certificate without
such legend or any other legend to the holder of the applicable Securities upon which it is stamped or issue to such holder by electronic delivery at the applicable balance account at the DTC, if (i) such Securities are registered for resale
under the Securities Act pursuant to an effective registration statement , (ii) such Securities are sold or transferred pursuant to and in compliance with Rule 144, or (iii) such Securities are eligible for sale under Rule 144,
without the requirement for the Company to be in compliance with the current public information required under Rule 144 as to such 

  
 23 

 
securities and without volume or manner-of-sale restrictions and are not being held by an Affiliate of the
Company. Following the earlier of (i) the effective date of a Registration Statement or (ii) Rule 144 becoming available for the resale of the Securities, without the requirement for the Company to be in compliance with the
current public information required under Rule 144 as to such Securities and without volume or manner-of-sale restrictions and the Securities are not held by an
Affiliate of the Company, the Company shall cause Company Counsel to issue to the Transfer Agent the legal opinion referred to in the Irrevocable Transfer Agent Instructions. Any fees (with respect to the Transfer Agent, Company Counsel or
otherwise) associated with the issuance of such opinion or the removal of such legend shall be borne by the Company. Following the date on which a Registration Statement is first declared effective by the Commission, or at such earlier time as
a legend is no longer required for certain Securities in accordance with this Agreement, the Company will no later than two (2) Trading Days following the delivery by a Purchaser to the Company (with notice to the Company) of a legended
certificate representing Securities (endorsed or with stock powers attached, signatures guaranteed, and otherwise in form necessary to affect the reissuance and/or transfer), and an opinion of counsel to the extent required by
Section 4.1(a), deliver or cause to be delivered to such Purchaser a certificate representing such Securities that is free from all restrictive and other legends. The Company may not make any notation on its records or
give instructions to the Transfer Agent that enlarge the restrictions on transfer set forth in this Section 4.1(c). Certificates for Securities subject to legend removal hereunder may be transmitted by the Transfer
Agent to the Purchasers by crediting the account of the Purchaser’s prime broker with DTC as directed by such Purchaser. 
 (ii) The
Company agrees that following such time as the legend is no longer required in accordance with this Agreement, it will, no later than two (2) Trading Days following the delivery by a Purchaser to the Transfer Agent of a (i) certificate
representing Securities issued with a restrictive legend if such Securities are certificated, or (ii) written notice requesting the removal of any restrictive legend from the entry in the applicable balance account evidencing such Securities,
as the case may be, deliver or cause to be delivered to such Purchaser such Securities, free from all restrictive and other legends, by crediting the account of the Purchaser’s prime broker with DTC System as directed by such Purchaser. The
Company may not make any notation on its records or give instructions to the Transfer Agent that enlarge the restrictions on transfer set forth in this Article IV. 

(d) Irrevocable Transfer Agent Instructions. The Company shall issue the Irrevocable Transfer Agent Instructions to the Transfer Agent.
The Company represents and warrants that no instruction other than the Irrevocable Transfer Agent Instructions referred to in this Section 4.1(d) (or instructions that are consistent therewith) will be given by the
Company to the Transfer Agent in connection with this Agreement, and that the Securities shall otherwise be freely transferable on the books and records of the Company as and to the extent provided in this Agreement and the other Transaction
Documents and applicable law. The Company acknowledges that a breach by it of its obligations under this Section 4.1(d) may cause irreparable harm to a Purchaser. Accordingly, the Company acknowledges that the remedy
at law for a breach of its obligations under this Section 4.1(d) may be inadequate and agrees, in the event of a breach or threatened breach by the Company of the provisions of this Section 4.1(d),
that a Purchaser shall be entitled, in addition to all other available remedies, to an order and/or injunction restraining any breach and requiring immediate issuance and transfer, without the necessity of showing economic loss and without any bond
or other security being required. 
 (e) Transfer to Affiliates. Notwithstanding any other provision of this Article IV to the
contrary, no registration statement or opinion of counsel shall be required for a transfer of the Securities by a Purchaser to an Affiliate of such Purchaser so long as the transferee of such Securities is an “accredited investor” and
agrees to be subject to the terms hereof to the same extent as transferor in its capacity as a Purchaser herein. 

  
 24 

 4.2 Furnishing of Information. In order to enable the Purchasers to sell the Securities
under Rule 144, until such time as no Purchaser holds Securities, the Company shall timely file (or obtain extensions in respect thereof and file within the applicable grace period) all reports required to be filed by the Company after the date
hereof pursuant to the Exchange Act. During such twelve (12) month period, if the Company is not required to file reports pursuant to the Exchange Act, it will prepare and furnish to the Purchasers and make publicly available in accordance with
Rule 144(c) such information as is required for the Purchasers to sell the Securities under Rule 144. 
 4.3
Integration. The Company shall not, and shall use its commercially reasonable efforts to ensure that no Affiliate of the Company shall, sell, offer for sale or solicit offers to buy or otherwise negotiate in respect of any security (as
defined in Section 2 of the Securities Act) that will be integrated with the offer or sale of the Securities in a manner that would require the registration under the Securities Act of the sale of the Securities to the Purchasers, or
that will be integrated with the offer or sale of the Securities for purposes of the rules and regulations of any Trading Market such that it would require stockholder approval prior to the closing of such other transaction unless
stockholder approval is obtained before the closing of such subsequent transaction. 
 4.4 Securities Laws Disclosure; Publicity. By
9:00 A.M., New York City time, on the Trading Day immediately following the date hereof, the Company shall issue a press release (the “Press Release”), reasonably acceptable to the Purchasers, disclosing all material terms of the
transactions contemplated hereby. On or before 9:00 A.M., New York City time, on the second Trading Day immediately following the execution of this Agreement, the Company will file a Current Report on Form 8-K
with the Commission describing the terms of the Transaction Documents, the Icon Acquisition and the Debt Financing (and including as exhibits to such Current Report on Form 8-K the material Transaction Documents (including, without
limitation, this Agreement and the Second Registration Rights Agreement)). Notwithstanding the foregoing, the Company shall not publicly disclose the name of any Purchaser or an Affiliate of any Purchaser, or include the name of any
Purchaser or an Affiliate of any Purchaser in any press release or filing with the Commission (other than the Registration Statement) or any regulatory agency or Trading Market, without the prior written consent of such Purchaser, which consent
shall not be unreasonably withheld, conditioned or delayed, except (i) as required by federal securities law or the rules or regulations of the Trading Market, including in connection with (A) any registration statement contemplated by the Second
Registration Rights Agreement and (B) the filing of final Transaction Documents (including signature pages thereto) with the Commission and (ii) to the extent such disclosure is required by law, request of the Staff of the Commission or Trading
Market regulations, in which case the Company shall provide the Purchasers with two days prior written notice, if permitted under applicable law or the rules or regulation of the Trading Market of such disclosure permitted under this subclause (ii).
From and after the issuance of the Press Release, no Purchaser shall be in possession of any material, non-public information received from the Company, any Subsidiary or any of their respective officers, directors, employees or agents, that is not
disclosed in the Press Release unless a Purchaser shall have executed a written agreement regarding the confidentiality and use of such information. Each Purchaser, severally and not jointly with the other Purchasers covenants that until such time
as the transactions contemplated by this Agreement are required to be publicly disclosed by the Company as described in this Section 4.4, such Purchaser will maintain the confidentiality of all disclosures made to it in connection with this
transaction (including the existence and terms of this transaction). 
 4.5 Indemnification of Purchasers.

(a) Subject to the provisions of this Section 4.5, the Company will indemnify and hold each Purchaser and its
directors, officers, stockholders, members, partners, employees and agents (and any other Persons with a functionally equivalent role of a Person holding such titles notwithstanding 

  
 25 

 
a lack of such title or any other title), each Person who controls such Purchaser (within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act), and the
directors, officers, stockholders, agents, members, partners or employees (and any other Persons with a functionally equivalent role of a Person holding such titles notwithstanding a lack of such title or any other title) of such controlling Persons
(each, a “Purchaser Party”) harmless from any and all losses, liabilities, obligations, claims, contingencies, damages, costs and expenses, including all judgments, amounts paid in settlements, court costs and reasonable
attorneys’ fees and costs of investigation that any such Purchaser Party may suffer or incur as a result of or relating to (a) any breach of any of the representations, warranties, covenants or agreements made by the Company in this
Agreement or in the other Transaction Documents or (b) any action instituted against a Purchaser in any capacity, or any of them or their respective Affiliates, by any stockholder of the Company who is not an Affiliate of such Purchaser
(including any derivative action brought by any stockholder on behalf of the Company), with respect to any of the transactions contemplated by the Transaction Documents (unless such action is based upon a breach of such Purchaser’s
representations, warranties or covenants under the Transaction Documents or any agreements or understandings such Purchaser may have with any such stockholder or any violations by the Purchaser of state or federal securities laws or any conduct by
such Purchaser which constitutes fraud, gross negligence, willful misconduct or malfeasance). 
 (b) Promptly after receipt by any Purchaser
Party (the “Indemnified Person”) of notice of any action, Proceeding or investigation in respect of which indemnity may be sought pursuant to this Section 4.5, such Indemnified Person shall promptly notify
the Company in writing and the Company shall assume the defense thereof, including the employment of counsel reasonably satisfactory to such Indemnified Person, and shall assume the payment of all reasonable fees and expenses; provided,
however, that the failure of any Indemnified Person so to notify the Company shall not relieve the Company of its obligations hereunder, except to the extent that the Company is actually and materially prejudiced by such failure to notify. In
any such Proceeding, any Indemnified Person shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Person unless: (i) the Company and the Indemnified Person shall
have mutually agreed to the retention of such counsel; (ii) the Company shall have failed promptly to assume the defense of such Proceeding and to employ counsel reasonably satisfactory to such Indemnified Person in such Proceeding; or
(iii) in the reasonable judgment of counsel to such Indemnified Person, representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them, in which case the Company shall be
responsible for the reasonable fees and expenses of no more than one such separate counsel and local counsel and shall pay such fees and expenses as incurred. The Company shall not be liable to any Indemnified Person under this Agreement for any
settlement of any Proceeding effected by the Indemnified Person without the Company’s written consent, which consent shall not be unreasonably withheld, delayed or conditioned, provided, however, that if at any time an Indemnified Person
shall have requested the Company to reimburse such Indemnified Person for fees and expenses of counsel as contemplated by this Section 4.5, and the Company has not reimbursed such Indemnified Party for such expenses within
thirty (30) days, the Company agrees that it shall be liable for any settlement of any proceeding effected without its written consent. Without the prior written consent of the Indemnified Person, which consent shall not be unreasonably
withheld, delayed or conditioned, the Company shall not effect any settlement, compromise, or consent to the entry of judgement in any pending or threatened action, suit or Proceeding in respect of which any Indemnified Person is or could have been
a party and indemnity could have been sought hereunder by such Indemnified Person, unless such settlement, compromise or consent includes an unconditional release of such Indemnified Person from any and all liability arising out of such Proceeding
and does not include any statement as to or any findings of fault, culpability or failure to act by or on behalf of any Indemnified Person. The indemnity agreements contained herein shall be in addition to any cause of action or similar right of any
Purchaser Party against the Company or others and any liabilities the Company may be subject to pursuant to law. 

  
 26 

 4.6 Company as Indemnitor of First Resort. The Company hereby acknowledges that a
Purchaser Party may have certain rights to indemnification, advancement of expenses or insurance, provided by Purchasers and certain of its affiliates (other than the Company and its subsidiaries, collectively, the “Fund
Indemnitors”). In the event that any Purchaser Party is made a party to or a participant in any Proceeding, to the extent resulting from any claim based on a Purchaser Party’s service to the Company as a director or other fiduciary of
the Company, then the Company shall (i) be an indemnitor of first resort (i.e., its obligations to such Purchaser Party are primary and any obligation of the Fund Indemnitors to advance expenses or to provide indemnification for the same
expenses or liabilities incurred by such Purchaser Party are secondary), (ii) be required to advance reasonable expenses incurred by such Purchaser Party, and (iii) be liable for the full amount of all expenses, judgments, penalties,
fines and amounts paid in settlement to the extent legally permitted and as required by the terms of this Agreement, the Delaware General Corporation Law, and any provision of the Company’s bylaws or Certificate of Incorporation, as amended (or
any other agreement between the Company and Purchaser), without regard to any rights such Purchaser Party may have against the Fund Indemnitors. The Company irrevocably waives, relinquishes and releases the Fund Indemnitors from any and all claims
against the Fund Indemnitors for contribution, subrogation or any other recovery of any kind in respect thereof. No advancement or payment by the Fund Indemnitors on behalf of a Purchaser Party with respect to any claim for which such Purchaser
Party has sought indemnification from the Company shall affect the foregoing and the Fund Indemnitors shall have a right of contribution or be subrogated to the extent of such advancement or payment to all of the rights of recovery of such Purchaser
Party against the Company. The Fund Indemnitors are third party beneficiaries of the terms of this Section 4.6. 
 4.7
Principal Trading Market Listing. In the time and manner required by the Principal Trading Market, the Company shall prepare and file with such Principal Trading Market an additional shares listing application covering all of the
Purchased Shares and Warrant Shares and shall use its commercially reasonable efforts to take all steps necessary to cause all of the Purchased Shares and Warrant Shares to be approved for listing on the Principal Trading Market as promptly as
possible thereafter. The Company shall comply with the rules and regulations of the ASX with respect to the issuance and sale of the Purchased Shares and Warrant Shares. 

4.8 Form D; Blue Sky. The Company agrees to timely file a Form D with respect to the Securities as required under Regulation D and to
provide a copy thereof to the Purchasers. The Company, on or before the Closing Date, shall take such action as the Company shall reasonably determine is necessary in order to obtain an exemption for or to qualify the Securities for sale to the
Purchasers under applicable securities or “Blue Sky” laws of the states of the United States (or to obtain an exemption from such qualification) and shall provide evidence of such actions promptly upon the written request of any Purchaser.

 4.9 Board Designee.  

(a) Director Designation Rights. Subject to Nasdaq Listing Rule 5640 (the “Voting Rights Rule”) and in the event that
the EW Purchasers purchase at least an aggregate of fifty percent (50%) of the Units offered by the Company pursuant to this Agreement at the Closing, for so long as the EW Purchasers (and their Affiliates) beneficially own Common Shares, including
any outstanding Warrant Shares, the EW Purchasers shall be entitled to designate for recommendation by the Governance and Nominating Committee of the Board of Directors pursuant to Section 4.9(c) and, upon such
recommendation, nomination by the Board of Directors, one (1) director from time to time as set forth below (any individual designated by the EW Purchasers, the “Purchaser Designee”). For the avoidance of doubt, the EW
Purchasers shall not be entitled to designate any Purchaser Designee pursuant to this Section 4.9(a) if at any time such designation would violate the Voting Rights Rule, after consultation

  
 27 

 
with Nasdaq. Notwithstanding the foregoing, each Purchaser Designee must be reasonably acceptable to the Governance and Nominating Committee of the Board of Directors and the Board of Directors.
The EW Purchasers may not assign the rights set forth in this Section 4.9(a) without the prior written consent of the Company. For the avoidance of doubt, the EW Purchasers’ right to designate a Purchaser Designee
hereunder is in addition to the EW Purchasers’ right to designate a director for the Board of Directors pursuant to Section 4.9 of the Initial Securities Purchase Agreement. In the event that Nasdaq informs the Company that it is not in
compliance with the Voting Rights Rule as a result of the EW Purchaser’s rights under this Section 4.9(a), each EW Purchaser shall cooperate with the Company to promptly remedy such
non-compliance, including relinquishing its right to a Purchaser Designee hereunder. 
 (b)
Initial Purchaser Designee. Immediately following the Closing, the size of the Board of Directors shall be 7 members and the Board of Directors shall appoint Dr. Göran Ando as the initial Purchaser Designee (the “Initial
Purchaser Designee”) to fill a vacancy on the Board of Directors with a term expiring at the Company’s next annual meeting of stockholders. 

(c) Compliance with Nominating Guidelines. Each Purchaser Designee, including the Initial Purchaser Designee, shall comply with the
requirements of the charter for, and related guidelines of, the Governance and Nominating Committee of the Board of Directors. 
 (d)
Additional Obligations. The Company agrees to take all necessary actions to cause (i) the individual designated in accordance with Section 4.9(a), and subject to the provisions of
Section 4.9(c), to be included in the slate of nominees to be elected to the Board of Directors at the next annual or special meeting of stockholders of the Company at which directors are to be elected, in accordance with
the Company’s certificate of incorporation, bylaws and Delaware General Corporation Law, and at each annual meeting of stockholders of the Company thereafter at which such director’s term expires, and to recommend that the Company’s
stockholders vote affirmatively for each such nominee and (ii) the individual designated in accordance with Section 4.9(e) to fill the applicable vacancy of the Board of Directors, in accordance with the Company’s
certificate of incorporation, bylaws, Delaware General Corporation Law, all applicable securities laws and the Principal Trading Market’s rules, regulations and standards. 

(e) Vacancies of Purchaser Designee. In the event that a vacancy is created at any time by the death, disability, retirement,
resignation or removal of the Purchaser Designee, the Company shall take at any time and from time to time all necessary action to cause the vacancy created thereby to be filled in accordance with the terms hereof as promptly as practicable by a new
Purchaser Designee designated by the EW Purchasers to the Board of Directors seat that has become vacant. 
 (f) Waiver of Corporate
Opportunities. In recognition that the Purchasers and Purchaser Designee currently have and will in the future have, or will consider, investments in numerous companies with respect to which Purchasers, Purchaser Designee or another
Purchaser Party may serve as an advisor, a director or in some other capacity, and in recognition that Purchasers, Purchaser Designee and other Purchaser Parties have myriad duties to various investors and partners, and in anticipation that the
Company and its Subsidiaries, on the one hand, and the Purchaser, Purchaser Designee and any other Purchaser Party, on the other hand, may engage in the same or similar activities or lines of business and have an interest in the same areas of
corporate opportunities, and in recognition of the benefits to be derived by the Company hereunder and in recognition of the difficulties which may confront any advisor who desires and endeavors fully to satisfy such advisor’s duties in
determining the full scope of such duties in any particular situation, the provisions of this Section 4.9(f) are set forth to regulate, define and guide the conduct of certain affairs of the Company as they may involve the
Purchasers, Purchaser Designee or Purchaser Party, and, except as the Purchasers and Purchaser Designee may otherwise agree in writing after the date hereof: 

  
 28 

 (i) the Purchasers, Purchaser Designee and any Purchaser Party will have the right: (A) to
directly or indirectly engage in any business (including, without limitation, any business activities or lines of business that are the same as or similar to those pursued by, or competitive with, the Company and its Subsidiaries), (B) to directly
or indirectly do business with any client or customer of the Company and its Subsidiaries, (C) to take any other action that the Purchaser, Purchaser Designee or Purchaser Party believes in good faith is necessary to or appropriate to fulfill
its obligations as described in the first sentence of this Section 4.9(f) to third parties and (D) not to communicate or present potential transactions, matters or business opportunities to the Company or any of its
Subsidiaries, and to pursue, directly or indirectly, any such opportunity for itself, and to direct any such opportunity to another Person or entity; and 

(ii) the Purchasers, Purchaser Designee and any Purchaser Party will have no duty (contractual or otherwise) to communicate or present any
corporate opportunities to the Company or any of its Affiliates or to refrain from any actions specified in the preceding paragraph, and the Company, on its own behalf and on behalf of its Affiliates, hereby renounces and waives any right to require
the Purchaser, Purchaser Designee or any Purchaser Party to act in a manner inconsistent with the provisions of this Section 4.9(f).  

(g) Benefits. During the period that a Purchaser Designee is a director of the Board of Directors, such director shall be entitled
to the same benefits, including benefits under any director and officer indemnification or insurance policy maintained by the Company, as any other non-employee director of the Board of Directors. 

4.10 Company Lock-Up. During the period beginning from the date hereof and continuing to and
including the earlier of (a) the Closing Date and (b) the date of the Company’s first meeting of stockholders at which the Company does not obtain Stockholder Approval (the “Lock Up Period”), the Company agrees that it
will not offer, sell, contract to sell, pledge, grant any option to purchase, make any short sale or otherwise dispose, except as provided hereunder, of any securities of the Company that are substantially similar to the Common Shares, including but
not limited to any options or warrants to purchase Common Shares or any securities that are convertible into or exchangeable for, or that represent the right to receive, Common Shares or any such substantially similar securities; provided,
however, that the Company may, without the consent of the Purchasers, (i) effect the transactions contemplated pursuant to this Agreement and the Initial Securities Purchase Agreement; (ii) issue the Warrants and the SWK Warrant and the Common
Shares issuable upon exercise thereof, (iii) issue Common Shares or options or stock units to purchase Common Shares, or issue Common Shares upon exercise of options or settlement of stock units, pursuant to any stock option, stock unit agreement,
stock bonus, employee stock purchase or other stock plan or arrangement described in the SEC Reports; (iv) issue Common Shares pursuant to the conversion or exchange of convertible or exchangeable securities outstanding as of the date of this
Agreement; (v) file a registration statement on Form S-8 to register Common Shares issuable pursuant to the terms of a stock option, stock bonus, employee stock purchase or other stock incentive plan or
arrangement described in the SEC Reports; (vi) issue Common Shares in connection with any joint venture, commercial or collaborative relationship or the acquisition or license by the Company of the securities, businesses, property or other assets of
another Person or entity which do not principally involve capital raising; provided, however, that in the case of clause (vi), such Common Shares shall not in the aggregate exceed 5% of the Company’s outstanding Common Shares on a fully
diluted basis after giving effect to the sale of the Securities contemplated by this Agreement; (vii) file the Registration Statement and the First Registration Statement in connection with this Agreement and the Initial Securities Purchase
Agreement; and (viii) assist any stockholder of the Company in the establishment of a trading plan by such stockholder pursuant to Rule 10b5-1 under the Exchange Act for the transfer of Common Shares, provided that such plan does not provide for the
transfer of Common Shares during the Lock Up Period, and the establishment of such plan does not require or otherwise result in any public filings or other public announcement of such plan during such Lock Up Period and such plan is otherwise
permitted to be implemented during the Lock Up Period pursuant to the terms of the Lock Up Agreement between such Person and the Purchasers, if any.

 4.11 Stockholder Approval. The Company shall use its best efforts to file a preliminary
proxy statement with the SEC no later than thirty (30) days after the First Closing, for the purpose of obtaining Stockholder Approval. The Company shall use its best efforts to hold a special meeting of its stockholders (which may also be the
annual meeting of stockholders) at the earliest practical date after the date hereof, but in no event later than ninety (90) days after the First Closing for the purpose of obtaining Stockholder Approval, with the recommendation of the
Board of Directors that such proposals are approved, and the Company shall solicit proxies from its stockholders in connection therewith in the same manner as all other management proposals in such proxy statement and all management-appointed
proxyholders shall vote their proxies in favor of such proposal. If the Company does not obtain Stockholder Approval at the first meeting held for such purpose, upon the written request of the EW Purchasers, the Company shall use its best efforts to
call another meeting of stockholders within six (6) months of the first meeting of stockholders held pursuant to this Section 4.11. 

4.12 Reservation of Purchased Shares and Warrant Shares. Upon receipt of Stockholder Approval, the Company shall maintain a reserve
free of pre-emptive rights, of a number of Common Shares equal to the number of Purchased Shares and the minimum number of Warrant Shares issuable pursuant to the exercise of the Warrants in such amount as may
then be required to fulfill its obligations in full under the Warrants.

 ARTICLE VI 

MISCELLANEOUS 
 6.1 Fees and

preparation, execution, delivery and performance of the Transaction Documents, the Initial Securities Purchase Agreement and the First Registration Rights Agreement; provided, however, that the Company shall reimburse the EW Purchasers for
all reasonable fees and expenses of the EW Purchasers incurred by the EW Purchasers in connection with the Transaction Documents, the Initial Securities Purchase Agreement and the First Registration Rights Agreement and the transactions contemplated
hereby and thereby, including fees and expenses related to due diligence, consultants, and the legal fees and expenses of counsel to the Purchasers in an amount not to exceed $400,000 in the aggregate, of which amount, up to $200,000 shall be
payable on the Closing and up to $200,000 shall have been paid upon the closing of the Initial Investment. The foregoing reimbursement obligations are intended to be identical to (and not in addition to) the reimbursement obligations set forth in

6.2 Entire Agreement. The Transaction Documents, together with the exhibits and schedules thereto, and the Initial Securities Purchase
Agreement and the First Registration Rights Agreement, together with the exhibits and schedules thereto, contain the entire understanding of the parties with respect to the subject matter hereof and supersede all prior agreements, understandings,
discussions and representations, oral or written, with respect to such matters, which the parties acknowledge have been merged into such documents, exhibits and schedules. At or after the Closing, and without further consideration, the Company and
the Purchasers will execute and deliver to the other such further documents as may be reasonably requested in order to give practical effect to the intention of the parties under the Transaction Documents.

 6.4 Amendments; Waivers; No Additional Consideration. No provision of this Agreement may be waived,
modified, supplemented or amended except in a written instrument signed, in the case of an amendment, by the Company and the Purchasers holding a majority of the Purchased Shares and Warrant Shares, in the case of a waiver, by the party against whom
enforcement of any such waiver is sought. No waiver of any default with respect to any provision, condition or requirement of this Agreement shall be deemed to be a continuing waiver in the future or a waiver of any subsequent default or a waiver of
any other provision, condition or requirement hereof, nor shall any delay or omission of either party to exercise any right hereunder in any manner impair the exercise of any such right. 

6.5 Construction. The headings herein are for convenience only, do not constitute a part of this Agreement and shall not be deemed
to limit or affect any of the provisions hereof. The language used in this Agreement will be deemed to be the language chosen by the parties to express their mutual intent, and no rules of strict construction will be applied against any
party. This Agreement shall be construed as if drafted jointly by the parties, and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of any provisions of this Agreement or any of the
Transaction Documents. 

  
 33 

 6.6 Successors and Assigns. The provisions of this Agreement shall inure to the benefit of
and be binding upon the parties and their successors and permitted assigns. The Company may not assign this Agreement, or any of its rights or obligations hereunder, without the prior written consent of the Purchasers holding a majority of the
Purchased Shares and Warrant Shares. Any Purchaser may assign its rights hereunder in whole or in part to any Person to whom such Purchaser assigns or transfers any Securities in compliance with the Transaction Documents and applicable law, provided
such transferee shall agree in writing to be bound, with respect to the transferred Securities, by the terms and conditions of this Agreement that apply to the “Purchasers”. 

6.7 No Third-Party Beneficiaries. This Agreement is intended for the benefit of the parties hereto and their respective successors
and permitted assigns and is not for the benefit of, nor may any provision hereof be enforced by, any other Person, except as otherwise set forth in Section 4.6. 

6.8 Governing Law. All questions concerning the construction, validity, enforcement and interpretation of this Agreement shall be
governed by and construed and enforced in accordance with the internal laws of the State of New York, without regard to the principles of conflicts of law thereof. Each party agrees that all Proceedings concerning the interpretations, enforcement
and defense of the transactions contemplated by this Agreement and any other Transaction Documents (whether brought against a party hereto or its respective Affiliates, employees or agents) shall be commenced exclusively in the New York Courts. Each
party hereto hereby irrevocably submits to the exclusive jurisdiction of the New York Courts for the adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein (including with
respect to the enforcement of any of the Transaction Documents), and hereby irrevocably waives, and agrees not to assert in any Proceeding, any claim that it is not personally subject to the jurisdiction of any such New York Court, or that such
Proceeding has been commenced in an improper or inconvenient forum. Each party hereto hereby irrevocably waives personal service of process and consents to process being served in any such Proceeding by mailing a copy thereof via registered or
certified mail or overnight delivery (with evidence of delivery) to such party at the address in effect for notices to it under this Agreement and agrees that such service shall constitute good and sufficient service of process and notice thereof.
Nothing contained herein shall be deemed to limit in any way any right to serve process in any manner permitted by law. EACH PARTY HERETO HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY
JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY. 
 6.9
Survival. Subject to applicable statute of limitations, the representations, warranties, agreements and covenants contained herein shall survive the Closing and the delivery of the Securities. 

6.10 Execution. This Agreement may be executed in two or more counterparts, all of which when taken together shall be considered
one and the same agreement and shall become effective when counterparts have been signed by each party and delivered to the other party, it being understood that both parties need not sign the same counterpart. In the event that any signature is
delivered by facsimile transmission, or by e-mail delivery of a “.pdf” format data file, such signature shall create a valid and binding obligation of the party executing (or on whose behalf such
signature is executed) with the same force and effect as if such facsimile signature page were an original thereof. 
 6.11
Severability. If any provision of this Agreement is held to be invalid or unenforceable in any respect, the validity and enforceability of the remaining terms and provisions of this Agreement shall not in any way be affected or impaired
thereby and the parties will attempt to agree upon a valid and enforceable provision that is a reasonable substitute therefor, and upon so agreeing, shall incorporate such substitute provision in this Agreement. 

  
 34 

 6.12 Replacement of Securities. If any certificate or instrument evidencing any Securities
is mutilated, lost, stolen or destroyed, the Company shall issue or cause to be issued in exchange and substitution for and upon cancellation thereof, or in lieu of and substitution therefor, a new certificate or instrument, but only upon receipt of
evidence reasonably satisfactory to the Company and the Transfer Agent of such loss, theft or destruction and the execution by the holder thereof of a customary lost certificate affidavit of that fact and an agreement to indemnify and hold harmless
the Company and the Transfer Agent for any losses in connection therewith or, if required by the Transfer Agent, a bond in such form and amount as is required by the Transfer Agent. The applicants for a new certificate or instrument under such
circumstances shall also pay any reasonable third-party costs associated with the issuance of such replacement Securities. If a replacement certificate or instrument evidencing any Securities is requested due to a mutilation thereof, the Company may
require delivery of such mutilated certificate or instrument as a condition precedent to any issuance of a replacement. 
 6.13
Remedies. In addition to being entitled to exercise all rights provided herein or granted by law, including recovery of damages, the Purchasers will be entitled to specific performance under the Transaction Documents. The parties agree that
monetary damages may not be adequate compensation for any loss incurred by the Purchasers by reason of any breach of obligations contained in this Agreement and hereby agree to waive and not assert in any action for specific performance of any such
obligation (other than in connection with any action for a temporary restraining order) the defense that a remedy at law would be adequate. 

6.14 Payment Set Aside. To the extent that the Company makes a payment or payments to any Purchaser pursuant to any
Transaction Document or a Purchaser enforces or exercises its rights thereunder, and such payment or payments or the proceeds of such enforcement or exercise or any part thereof are subsequently invalidated, declared to be fraudulent or
preferential, set aside, recovered from, disgorged by or are required to be refunded, repaid or otherwise restored to the Company, a trustee, receiver or any other Person under any law (including, without limitation, any bankruptcy law, state or
federal law, common law or equitable cause of action), then to the extent of any such restoration the obligation or part thereof originally intended to be satisfied shall be revived and continued in full force and effect as if such payment had not
been made or such enforcement or setoff had not occurred. 
 6.15 Adjustments in Share Numbers and Prices. In the event of any stock
split, subdivision, dividend or distribution payable in shares of Common Shares (or other securities or rights convertible into, or entitling the holder thereof to receive directly or indirectly shares of Common Shares), combination or other similar
recapitalization or event occurring after the date hereof and prior to the Closing, each reference in any Transaction Document to a number of shares or a price per share shall be deemed to be amended to appropriately account for such event. 

6.16 Independent Nature of Purchasers’ Obligations and Rights. The obligations of each Purchaser under any Transaction
Document are several and not joint with the obligations of any other Purchaser, and no Purchaser shall be responsible in any way for the performance of the obligations of any other Purchaser under any Transaction Document. The decision
of each Purchaser to purchase Securities pursuant to the Transaction Documents has been made by such Purchaser independently of any other Purchaser and independently of any information, materials, statements or opinions as to the business, affairs,
operations, assets, properties, liabilities, results of operations, condition (financial or otherwise) or prospects of the Company or any Subsidiary which may have been made or given by any other Purchaser or by any agent or employee of any other
Purchaser, and no Purchaser and any of its agents or employees shall have any liability to any other Purchaser (or any other Person) relating to or arising from any such 

  
 35 

 
information, materials, statement or opinions. Nothing contained herein or in any Transaction Document, and no action taken by any Purchaser pursuant thereto, shall be deemed to constitute
the Purchasers as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Purchasers are in any way acting in concert or as a group with respect to such obligations or the transactions
contemplated by the Transaction Documents. Each Purchaser acknowledges that no other Purchaser has acted as agent for such Purchaser in connection with making its investment hereunder and that no Purchaser will be acting as agent of such
Purchaser in connection with monitoring its investment in the Securities or enforcing its rights under the Transaction Documents. Each Purchaser shall be entitled to independently protect and enforce its rights, including without limitation the
rights arising out of this Agreement or out of the other Transaction Documents, and it shall not be necessary for any other Purchaser to be joined as an additional party in any Proceeding for such purpose. Each Purchaser has been represented by
its own separate legal counsel in its review and negotiation of the Transaction Documents.
 6.17 Termination. This Agreement
may be terminated and the sale and purchase of the Securities abandoned at any time prior to the Closing by either the Company or any Purchaser (with respect to itself only) upon written notice to the other, if the Closing has not been consummated
on or prior to 5:00 P.M., New York City time, on December 31, 2018. Nothing in this Section 6.17 shall be deemed to release any party from any liability for any breach by such party of the terms and provisions of this Agreement or the other
Transaction Documents or to impair the right of any party to compel specific performance by any other party of its obligations under this Agreement or the other Transaction Documents. In the event of a termination pursuant to this Section
6.17, the Company shall promptly notify all non-terminating Purchasers. Upon a termination in accordance with this Section 6.17, the Company and the terminating Purchaser(s) shall not have any further obligation or liability (including
arising from such termination) to the other, except as provided in Section 4.5, Section 4.6 and Section 6.1, and no Purchaser will have any liability to any other Purchaser under the Transaction Documents as a result therefrom.

	Warrant Shares: _________________	  		  	Initial Exercise Date: ______, 201__
		  		  	Issue Date: ______, 2018

 THIS COMMON STOCK PURCHASE WARRANT (the “Warrant”) certifies that, for value received,
_____________ or its assigns (the “Holder”) is entitled, upon the terms and subject to the limitations on exercise and the conditions hereinafter set forth, at any time on or after the Second Closing (the “Initial Exercise
Date”) and on or prior to the close of business on the fifteenth (15th) Business Day following the date on which the Holder receives written notice from the Company that the Centers for
Medicare & Medicaid Services has announced that a new C-Code has been established for DexycuTM and will be effective at the start of the first
calendar quarter after such notice (the “Termination Date”), but not thereafter, to subscribe for and purchase from pSivida Corp., a Delaware corporation (the “Company”), up to
                 shares of common stock, par value $0.001 per share (the “Common Shares”), of the Company (as subject to adjustment hereunder,
the “Warrant Shares”). The purchase price of one Common Share under this Warrant shall be equal to the Exercise Price, as defined in Section 2(b). 

Section 1. Definitions. Capitalized terms used and not otherwise defined herein shall have the meanings set
forth in that certain Securities Purchase Agreement, dated as of March 28, 2018, among the Company and the purchasers signatory thereto (the “Second Securities Purchase Agreement”). 

Section 2. Exercise. 

a) Exercise of Warrant. Exercise of the purchase rights represented by this Warrant may be made, in whole or in part, at
any time or times on or after the Initial Exercise Date and on or before the Termination Date by delivery to the Company (or such other office or agency that the Company may designate by notice in writing to the registered Holder at the address of
the Holder appearing on the books of the Company) of 

 
a duly executed facsimile copy or PDF copy submitted by electronic (or e-mail attachment) of the Notice of Exercise in the form annexed hereto. Within the
earlier of (i) three (3) Trading Days and (ii) the number of Trading Days comprising the Standard Settlement Period (as defined in Section 2(d)(i) herein) following the date of exercise as aforesaid, the Holder shall deliver the
aggregate Exercise Price for the shares specified in the applicable Notice of Exercise by wire transfer or cashier’s check drawn on a United States bank. No ink-original Notice of Exercise shall be
required, nor shall any medallion guarantee (or other type of guarantee or notarization) of any Notice of Exercise form be required. Notwithstanding anything herein to the contrary, the Holder shall not be required to physically surrender this
Warrant to the Company until the Holder has purchased all of the Warrant Shares available hereunder and the Warrant has been exercised in full, in which case, the Holder shall surrender this Warrant to the Company for cancellation within three
(3) Trading Days of the date the final Notice of Exercise is delivered to the Company. Partial exercises of this Warrant resulting in purchases of a portion of the total number of Warrant Shares available hereunder shall have the effect of
lowering the outstanding number of Warrant Shares purchasable hereunder in an amount equal to the applicable number of Warrant Shares purchased. The Holder and the Company shall maintain records showing the number of Warrant Shares purchased and the
date of such purchases. The Company shall deliver any objection to any Notice of Exercise within one (1) Business Day of receipt of such notice. The Holder and any assignee, by acceptance of this Warrant, acknowledge and agree that, by
reason of the provisions of this paragraph, following the purchase of a portion of the Warrant Shares hereunder, the number of Warrant Shares available for purchase hereunder at any given time may be less than the amount stated on the face
hereof. 
 b) Exercise Price. The exercise price per Warrant Share under this Warrant shall be equal to the lower
of (i) $1.43, (a thirty percent (30%) premium to the Initial Purchase Price), or (ii) a 20% discount to the VWAP of the Common Shares on the Principal Trading Market for the twenty (20) Trading Days immediately prior to the exercise of
this Warrant; provided that in no event shall the exercise price per Warrant Share be lower than $0.88, (a twenty percent (20%) discount to the Initial Purchase Price), subject to adjustment hereunder (the “Exercise Price”).

 “VWAP” shall mean, for any date, the price determined by the first of the following clauses that applies:
(a) if the Common Shares are then listed or quoted on a Trading Market, the daily volume weighted average price of the Common Shares for such date (or the nearest preceding date) on the Trading Market on which the Common Shares are then listed
or quoted as reported by Bloomberg L.P. (based on a Trading Day from 9:30 a.m. (New York City time) to 4:02 p.m. (New York City time)) or (b) in all other cases, the fair market value of a share of Common Shares as determined by an independent
appraiser selected in good faith and mutually agreed upon between the Company and the Holder, the fees and expenses of which shall be paid by the Company. 

c) Cashless Exercise. This Warrant may not be exercised, in whole or in part, by means of a “cashless
exercise”. 

  
 2 

 d) Mechanics of Exercise. 

i. Delivery of Warrant Shares Upon Exercise. Warrant Shares purchased hereunder shall be transmitted by the Transfer
Agent to the Holder by crediting the account of the Holder’s or its designee’s balance account with The Depository Trust Company through its Deposit or Withdrawal at Custodian system (“DWAC”) if the Company is then a
participant in such system and either (A) there is an effective registration statement permitting the issuance of the Warrant Shares to or resale of the Warrant Shares by the Holder or (B) the Warrant Shares are eligible for resale by the
Holder without volume or manner-of-sale limitations pursuant to Rule 144, and otherwise by physical delivery of a certificate, registered in the Company’s share
register in the name of the Holder or its designee, for the number of Warrant Shares to which the Holder is entitled pursuant to such exercise to the address specified by the Holder in the Notice of Exercise by the date that is the earlier of
(i) three (3) Trading Days and (ii) the number of Trading Days comprising the Standard Settlement Period after the delivery to the Company of the Notice of Exercise (such date, the “Warrant Share Delivery Date”). Upon
delivery of the Notice of Exercise, the Holder shall be deemed for all corporate purposes to have become the holder of record of the Warrant Shares with respect to which this Warrant has been exercised, irrespective of the date of delivery of the
Warrant Shares, provided that payment of the aggregate Exercise Price is received within the earlier of (i) three (3) Trading Days and (ii) the number of Trading Days comprising the Standard Settlement Period following delivery of the
Notice of Exercise. Subject to the Company’s receipt of the aggregate Exercise Price for the Warrant Shares subject to a Notice of Exercise, if the Company fails for any reason to deliver to the Holder the Warrant Shares subject to such Notice
of Exercise by the Warrant Share Delivery Date, the Company shall pay to the Holder, in cash, as liquidated damages and not as a penalty, for each $1,000 of Warrant Shares subject to such exercise (based on the VWAP of the Common Shares on the date
of the applicable Notice of Exercise), $10 per Trading Day (increasing to $20 per Trading Day on the fifth Trading Day after such liquidated damages begin to accrue) for each Trading Day after such Warrant Share Delivery Date until such Warrant
Shares are delivered or Holder rescinds such exercise. The Company agrees to maintain a transfer agent that is a participant in the FAST program so long as this Warrant remains outstanding and exercisable. As used herein, “Standard
Settlement Period” means the standard settlement period, expressed in a number of Trading Days, on the Company’s primary Trading Market with respect to the Common Shares as in effect on the date of delivery of the Notice of Exercise.

  
 3 

 ii. Delivery of New Warrants Upon Exercise. If this Warrant shall have
been exercised in part, the Company shall, at the request of a Holder and upon surrender of this Warrant certificate, at the time of delivery of the Warrant Shares, deliver to the Holder a new Warrant evidencing the rights of the Holder to purchase
the unpurchased Warrant Shares called for by this Warrant, which new Warrant shall in all other respects be identical with this Warrant. 

iii. Rescission Rights. Subject to the Company’s receipt of the aggregate Exercise Price for the Warrant Shares
subject to such Notice of Exercise, if the Company fails to cause the Transfer Agent to transmit to the Holder the Warrant Shares pursuant to Section 2(d)(i) by the Warrant Share Delivery Date, then the Holder will have the right to rescind
such exercise. 
 iv. Compensation for Buy-In on Failure to Timely Deliver Warrant
Shares Upon Exercise. In addition to any other rights available to the Holder, if the Company fails to cause the Transfer Agent to transmit to the Holder the Warrant Shares in accordance with the provisions of Section 2(d)(i) above pursuant
to an exercise on or before the Warrant Share Delivery Date, and if after such date the Holder is required by its broker to purchase (in an open market transaction or otherwise) or the Holder’s brokerage firm otherwise purchases, Common Shares
to deliver in satisfaction of a sale by the Holder of the Warrant Shares which the Holder anticipated receiving upon such exercise (a “Buy-In”), then the Company shall (A) pay in cash to
the Holder the amount, if any, by which (x) the Holder’s total purchase price (including brokerage commissions, if any) for the Common Shares so purchased exceeds (y) the amount obtained by multiplying (1) the number of Warrant
Shares that the Company was required to deliver to the Holder in connection with the exercise at issue times (2) the price at which the sell order giving rise to such purchase obligation was executed, and (B) at the option of the Holder,
either reinstate the portion of the Warrant and equivalent number of Warrant Shares for which such exercise was not honored (in which case such exercise shall be deemed rescinded) or deliver to the Holder the number of Warrant Shares that would have
been issued had the Company timely complied with its exercise and delivery obligations hereunder. For example, if the Holder purchases Common Shares having a total purchase price of $11,000 to cover a Buy-In
with respect to an attempted exercise of Warrant Shares with an aggregate sale price giving rise to such purchase obligation of $10,000, under clause (A) of the immediately preceding sentence the Company shall be required to pay the Holder
$1,000. The Holder shall provide the Company written notice indicating the amounts payable to the Holder in respect of the Buy-In and, upon request of the Company, evidence of the amount of such loss. Nothing
herein shall limit a Holder’s right to pursue any other remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief with respect to the Company’s failure
to timely deliver Warrant Shares upon exercise of the Warrant as required pursuant to the terms hereof. 

  
 4 

 v. No Fractional Shares or Scrip. No fractional shares or scrip
representing fractional shares shall be issued upon the exercise of this Warrant. As to any fraction of a share which the Holder would otherwise be entitled to purchase upon such exercise, the Company shall, at its election, either pay a cash
adjustment in respect of such final fraction in an amount equal to such fraction multiplied by the Exercise Price or round up to the next whole share. 

vi. Charges, Taxes and Expenses. Issuance of Warrant Shares shall be made without charge to the Holder for any issue or
transfer tax or other incidental expense in respect of the issuance of such Warrant Shares, all of which taxes and expenses shall be paid by the Company, and such Warrant Shares shall be issued in the name of the Holder or in such name or names as
may be directed by the Holder; provided, however, that in the event that Warrant Shares are to be issued in a name other than the name of the Holder, this Warrant when surrendered for exercise shall be accompanied by the Assignment
Form attached hereto duly executed by the Holder and the Company may require, as a condition thereto, the payment of a sum sufficient to reimburse it for any transfer tax incidental thereto. The Company shall pay all Transfer Agent fees required for
same-day processing of any Notice of Exercise and all fees to the Depository Trust Company (or another established clearing corporation performing similar functions) required for
same-day electronic delivery of the Warrant Shares. 
 vii. Closing of Books.
The Company will not close its shareholder books or records in any manner which prevents the timely exercise of this Warrant, pursuant to the terms hereof. 

Section 3. Certain Adjustments. 

a) Stock Dividends and Splits. If the Company, at any time while this Warrant is outstanding: (i) pays a stock
dividend or otherwise makes a distribution or distributions on its Common Shares or any other equity or equity equivalent securities payable in Common Shares (which, for avoidance of doubt, shall not include any Common Shares issued by the Company
upon exercise of this Warrant), (ii) subdivides outstanding Common Shares into a larger number of shares, (iii) combines (including by way of reverse stock split) outstanding Common Shares into a smaller number of shares or (iv) issues by
reclassification of Common Shares any shares of capital stock of the Company, then in each case the Exercise Price shall be multiplied by a fraction of which the numerator shall be the number of Common Shares (excluding treasury shares, if any)
outstanding immediately before such event and of which the denominator shall be the number of Common Shares outstanding immediately after such event, and the number of shares issuable upon exercise of this Warrant shall be proportionately adjusted
such that 

  
 5 

 
the aggregate Exercise Price of this Warrant shall remain unchanged. Any adjustment made pursuant to this Section 3(a) shall become effective immediately after the record date for the
determination of shareholders entitled to receive such dividend or distribution and shall become effective immediately after the effective date in the case of a subdivision, combination or re-classification.

 b) Subsequent Rights Offerings. In addition to any adjustments pursuant to Section 3(a) above, if at any time
the Company grants, issues or sells any Common Share equivalents or rights to purchase stock, warrants, securities or other property pro rata to the record holders of any class of Common Shares (the “Purchase Rights”), then the
Holder will be entitled to acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights which the Holder could have acquired if the Holder had held the number of Common Shares acquirable upon complete exercise of this
Warrant immediately before the date on which a record is taken for the grant, issuance or sale of such Purchase Rights, or, if no such record is taken, the date as of which the record holders of Common Shares are to be determined for the grant,
issue or sale of such Purchase Rights. 
 c) Pro Rata Distributions. During such time as this Warrant is outstanding,
if the Company shall declare or make any dividend or other distribution of its assets (or rights to acquire its assets) to holders of its Common Shares, by way of return of capital or otherwise (including, without limitation, any distribution of
cash, stock or other securities, property or options by way of a dividend, spin off, reclassification, corporate rearrangement, scheme of arrangement or other similar transaction) (a “Distribution”), at any time after the issuance
of this Warrant, then, in each such case, the Holder shall be entitled to participate in such Distribution to the same extent that the Holder would have participated therein if the Holder had held the number of Common Shares acquirable upon complete
exercise of this Warrant immediately before the date of which a record is taken for such Distribution, or, if no such record is taken, the date as of which the record holders of Common Shares are to be determined for the participation in such
Distribution. To the extent that this Warrant has not been partially or completely exercised at the time of such Distribution, such portion of the Distribution shall be held in abeyance for the benefit of the Holder until the Holder has exercised
this Warrant. 
 d) Treatment Upon an Acquisition. 

i. In the event of an Acquisition (as defined below) prior to the Termination Date (other than, for the purposes of this
provision, an Acquisition consummated by way of an unsolicited third-party offer), the Company shall use its best efforts to ensure that lawful and adequate provision shall be made whereby each Holder shall thereafter continue to have the right to
subscribe for Common Shares in lieu of the Warrant Shares issuable upon exercise of the Warrants held by such Holder, such number of shares, where the value of each new warrant to purchase one share in the surviving or acquiring entity
(“Acquirer”) is determined in accordance with the Black-Scholes Option Pricing formula set forth in Appendix (A) hereto, that is equivalent to the aggregate value of the 

  
 6 

 
Warrants held by such Holder, where the value of each Warrant to purchase one Common Share in the Company is determined in accordance with the Black-Scholes Option Pricing formula set forth
Appendix (B) hereto. Furthermore, the new warrants to purchase shares in the Acquirer referred to herein shall have the same expiration date as the Warrants, and shall have a strike price,
KAcq, that is calculated in accordance with Appendix (A) hereto. For the avoidance of doubt, if the Acquirer surviving or acquiring entity, as the case may be, is a member of a
consolidated group for financial reporting purposes, the “Acquirer” shall be deemed to be the parent of such consolidated group for purposes of this Section 3(d) and Appendix (A) hereto. 

ii. Moreover, appropriate provision shall be made with respect to the rights and interests of each Holder to the end that the
provisions hereof (including, without limitation, provision for adjustment of the Exercise Price) shall thereafter be applicable, as nearly equivalent as may be practicable in relation to any shares thereafter deliverable upon the exercise thereof.
The Company shall not effect any such Acquisition unless prior to or simultaneously with the consummation thereof the successor corporation resulting from such consolidation or merger, or the corporation purchasing or otherwise acquiring such assets
or other appropriate corporation or entity shall assume by written instrument, reasonably deemed by the Board of Directors of the Company and the Holder to be satisfactory in form and substance, the obligation to deliver to the holder of the
Warrants, at the last address of such holder appearing on the books of the Company, such shares of stock, as, in accordance with the foregoing provisions, such holder may be entitled to purchase, and the other obligations under these Warrants. The
provisions of this Section 3(d) shall similarly apply to successive Acquisitions. 
 iii. If the Company, in spite of
using its commercially reasonable efforts, is unable to cause these Warrants to continue in full force and effect until the expiration of the Termination Date in connection with any Acquisition, then the Company shall pay the Holders an
amount per Warrant to purchase one Common Share that is calculated in accordance with the Black-Scholes Option Pricing formula set forth in Appendix (B) hereto (the “Black-Scholes Value”). Such payment shall be made in
cash in the event that the Acquisition results in the shareholders of the Company receiving cash from the Acquirer at the closing of the transaction, and shall be made in shares of the Company (with the value of each Common Share determined
according to SCorp in Appendix (B) hereto) in the event that the Acquisition results in the shareholders of the Company receiving shares in the Acquirer or other entity at the
closing of the transaction. In the event that the shareholders of the Company receive both cash and shares at the closing of the transaction, such payment to the Holders shall also be made in both cash and shares in the same proportion as the
consideration received by the shareholders. Following any payment required pursuant to this 3(d)(iii), the Warrant shall terminate, without payment of any additional consideration therefor. 

  
 7 

 iv. Notwithstanding the foregoing, in the event that, as a result of the
Acquisition, the Warrants will be exercisable for anything other than shares or securities that are listed on a United States national securities exchange, the Holder shall be entitled to demand to receive a cash payment in an amount equal to the
Black-Scholes Value per Warrant (calculated in accordance with Appendix B attached hereto) contemporaneously with or promptly after the consummation of such Acquisition. Following any such demand, the Warrant shall terminate, without payment
of any consideration other than the Black-Scholes Value therefor, effective upon the payment of such amount. 
 v.
“Acquisition” means any of the following: (i) any sale, lease, license, transfer, conveyance or other disposition of all or substantially all of the assets of the Company; (ii) any reorganization, consolidation, merger,
demerger or sale of shares of the Company (including, without limitation, a public tender offer for the shares in the Company) where the holders of the Company’s outstanding shares as of immediately before the transaction (or series of related
transactions) beneficially own less than a majority by voting powers of the outstanding shares of the surviving or successor entity as of immediately after the transaction; or (iii) the acquisition by any “person” (together with such
person’s Affiliates) or “group” (within the meaning of Section 13(d) or 14(d) of the Exchange Act) acquires, directly or indirectly, the beneficial ownership (as such term is defined in Rule
13d-3 promulgated under the Exchange Act) of outstanding shares of capital stock and/or other equity securities of the Company, in a single transaction or series of related transactions (including, without
limitation, one or more tender offers or exchange offers), representing at least 50% of the voting power of or economic interests in the then outstanding shares of capital stock of the Company. Notwithstanding the foregoing, the term Acquisition
shall not include the Common Shares, including the Warrant Shares, purchased by the holder pursuant to that certain Securities Purchase Agreement by and among the Company and the purchasers signatory thereto dated as of March 28, 2018 and the
Second Securities Purchase Agreement. 
 e) Calculations. All calculations under this Section 3 shall be made to
the nearest cent or the nearest 1/100th of a share, as the case may be. For purposes of this Section 3, the number of Common Shares deemed to be issued and outstanding as of a given date shall be the sum of the number of Common Shares
(excluding treasury shares, if any) issued and outstanding. 

  
 8 

 f) Notice to Holder. 

i. Adjustment to Exercise Price. Whenever the Exercise Price is adjusted pursuant to any provision of this
Section 3, the Company shall promptly deliver to the Holder by facsimile or email a notice setting forth the Exercise Price after such adjustment and any resulting adjustment to the number of Warrant Shares and setting forth a brief statement
of the facts requiring such adjustment. 
 ii. Notice to Allow Exercise by Holder. If (A) the Company shall
declare a dividend (or any other distribution in whatever form) on its Common Shares, (B) the Company shall declare a special nonrecurring cash dividend on or a redemption of the Common Shares, (C) the Company shall authorize the granting
to all holders of Common Shares rights or warrants to subscribe for or purchase any shares of capital stock of any class or of any rights, (D) the approval of any shareholders of the Company shall be required in connection with any
reclassification of the Common Shares, any consolidation or merger to which the Company is a party, any sale or transfer of all or substantially all of the assets of the Company, or any compulsory share exchange whereby the Common Shares are
converted into other securities, cash or property, or (E) the Company shall authorize the voluntary or involuntary dissolution, liquidation or winding up of the affairs of the Company, then, in each case, the Company shall cause to be delivered
by facsimile or email to the Holder at its last facsimile number or email address as it shall appear upon the Warrant Register of the Company, at least 20 calendar days prior to the applicable record or effective date hereinafter specified, a notice
stating (x) the date on which a record is to be taken for the purpose of such dividend, distribution, redemption, rights or warrants, or if a record is not to be taken, the date as of which the holders of the Common Shares of record to be
entitled to such dividend, distributions, redemption, rights or warrants are to be determined or (y) the date on which such reclassification, consolidation, merger, sale, transfer or share exchange is expected to become effective or close, and
the date as of which it is expected that holders of the Common Shares of record shall be entitled to exchange their Common Shares for securities, cash or other property deliverable upon such reclassification, consolidation, merger, sale, transfer or
share exchange; provided that the failure to deliver such notice or any defect therein or in the delivery thereof shall not affect the validity of the corporate action required to be specified in such notice. To the extent that any notice
provided in this Warrant constitutes, or contains, material, non-public information regarding the Company or any of the Subsidiaries, the Company shall simultaneously file such notice with the Commission
pursuant to a Current Report on Form 8-K. The Holder shall remain entitled to exercise this Warrant during the period commencing on the date of such notice to the effective date of the event triggering such
notice except as may otherwise be expressly set forth herein. 

  
 9 

 Section 4. Transfer of Warrant. 

a) Transferability. Subject to the provisions of Section 4.1 of the Purchase Agreement and applicable securities
law, this Warrant and all rights hereunder (including, without limitation, any registration rights) are transferable, in whole or in part, upon surrender of this Warrant at the principal office of the Company or its designated agent, together with a
written assignment of this Warrant substantially in the form attached hereto duly executed by the Holder or its agent or attorney and funds sufficient to pay any transfer taxes payable upon the making of such transfer. If, at the time of a transfer,
the Warrant Shares have not been registered pursuant to an effective registration statement, then, prior to any such transfer, the transferee shall deliver a written statement to the Company that such transferee is an “accredited investor as
defined in Rule 501(a) promulgated under the Securities Act. Upon such surrender and, if required, such payment, the Company shall execute and deliver a new Warrant or Warrants in the name of the assignee or assignees, as applicable, and in the
denomination or denominations specified in such instrument of assignment, and shall issue to the assignor a new Warrant evidencing the portion of this Warrant not so assigned, and this Warrant shall promptly be cancelled. Notwithstanding anything
herein to the contrary, the Holder shall not be required to physically surrender this Warrant to the Company unless the Holder has assigned this Warrant in full, in which case, the Holder shall surrender this Warrant to the Company within three
(3) Trading Days of the date the Holder delivers an assignment form to the Company assigning this Warrant full. The Warrant, if properly assigned in accordance herewith, may be exercised by a new holder for the purchase of Warrant Shares
without having a new Warrant issued. 
 b) New Warrants. This Warrant may be divided or combined with other Warrants
upon presentation hereof at the aforesaid office of the Company, together with a written notice specifying the names and denominations in which new Warrants are to be issued, signed by the Holder or its agent or attorney. Subject to compliance with
Section 4(a), as to any transfer which may be involved in such division or combination, the Company shall execute and deliver a new Warrant or Warrants in exchange for the Warrant or Warrants to be divided or combined in accordance with such
notice. All Warrants issued on transfers or exchanges shall be dated the Issue Date and shall be identical with this Warrant except as to the number of Warrant Shares issuable pursuant thereto. 

c) Warrant Register. The Company shall register this Warrant, upon records to be maintained by the Company for that
purpose (the “Warrant Register”), in the name of the record Holder hereof from time to time. The Company may deem and treat the registered Holder of this Warrant as the absolute owner hereof for the purpose of any exercise hereof or
any distribution to the Holder, and for all other purposes, absent actual notice to the contrary. 
 Section 5.
Miscellaneous. 
 a) No Rights as Shareholder Until Exercise. This Warrant does not entitle the Holder to any
voting rights, dividends or other rights as a shareholder of the Company prior to the exercise hereof as set forth in Section 2(d)(i), except as expressly set forth in Section 3. 

  
 10 

 b) Loss, Theft, Destruction or Mutilation of Warrant. The Company
covenants that upon receipt by the Company of evidence reasonably satisfactory to it of the loss, theft, destruction or mutilation of this Warrant or any stock certificate relating to the Warrant Shares, and in case of loss, theft or destruction, of
indemnity or security reasonably satisfactory to it (which, in the case of the Warrant, shall not include the posting of any bond), and upon surrender and cancellation of such Warrant or stock certificate, if mutilated, the Company will make and
deliver a new Warrant or stock certificate of like tenor and dated as of such cancellation, in lieu of such Warrant or stock certificate. 

c) Saturdays, Sundays, Holidays, etc. If the last or appointed day for the taking of any action or the expiration of any
right required or granted herein shall not be a Business Day, then, such action may be taken or such right may be exercised on the next succeeding Business Day. 

d) Authorized Shares. 

The Company covenants that, during the period the Warrant is outstanding, it will reserve from its authorized and unissued
Common Shares a sufficient number of Common Shares to provide for the issuance of the Warrant Shares upon the exercise of any purchase rights under this Warrant. The Company further covenants that its issuance of this Warrant shall constitute full
authority to its officers who are charged with the duty of issuing the necessary Warrant Shares upon the exercise of the purchase rights under this Warrant. The Company will take all such reasonable action as may be necessary to assure that such
Warrant Shares may be issued as provided herein without violation of any applicable law or regulation, or of any requirements of the Trading Market upon which the Common Shares may be listed. The Company covenants that all Warrant Shares which may
be issued upon the exercise of the purchase rights represented by this Warrant will, upon exercise of the purchase rights represented by this Warrant and payment for such Warrant Shares in accordance herewith, be duly authorized, validly issued,
fully paid and nonassessable and free from all taxes, liens and charges created by the Company in respect of the issue thereof (other than taxes in respect of any transfer occurring contemporaneously with such issue). 

Except and to the extent as waived or consented to by the Holder, the Company shall not by any action, including, without
limitation, amending its certificate of incorporation or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or
performance of any of the terms of this Warrant, but will at all times in good faith assist in the carrying out of all such terms and in the taking of all such actions as may be necessary or appropriate to protect the rights of Holder as set forth
in this Warrant against impairment. Without limiting the generality of the foregoing, the Company will (i) not increase the par value of any Warrant Shares above the amount payable therefor upon such exercise immediately prior to such increase

  
 11 

 
in par value, (ii) take all such action as may be necessary or appropriate in order that the Company may validly and legally issue fully paid and nonassessable Warrant Shares upon the
exercise of this Warrant and (iii) use commercially reasonable efforts to obtain all such authorizations, exemptions or consents as may be necessary to enable the Company to perform its obligations under this Warrant. 

e) Jurisdiction. All questions concerning the construction, validity, enforcement and interpretation of this Warrant
shall be determined in accordance with the provisions of the Purchase Agreement. 
 f) Restrictions. The Holder
acknowledges that the Warrant Shares acquired upon the exercise of this Warrant, if not registered will be subject to restriction upon resale imposed by state and federal securities laws. 

g) Nonwaiver and Expenses. No course of dealing or any delay or failure to exercise any right hereunder on the part of
Holder shall operate as a waiver of such right or otherwise prejudice the Holder’s rights, powers or remedies, notwithstanding the fact that all rights hereunder terminate on the Termination Date. If the Company willfully and knowingly fails to
comply with any provision of this Warrant, which results in any material damages to the Holder, the Company shall pay to the Holder such amounts as shall be sufficient to cover any costs and expenses including, but not limited to, reasonable
attorneys’ fees, including those of appellate proceedings, incurred by the Holder in collecting any amounts due pursuant hereto or in otherwise enforcing any of its rights, powers or remedies hereunder. 

h) Notices. Any notice, request or other document required or permitted to be given or delivered to the Holder by the
Company shall be delivered in accordance with the notice provisions of the Purchase Agreement. 
 i) Limitation of
Liability. No provision hereof, in the absence of any affirmative action by the Holder to exercise this Warrant to purchase Warrant Shares, and no enumeration herein of the rights or privileges of the Holder, shall give rise to any liability of
the Holder for the purchase price of any Warrant Shares or as a shareholder of the Company, whether such liability is asserted by the Company or by creditors of the Company. 

j) Remedies. The Holder, in addition to being entitled to exercise all rights granted by law, including recovery of
damages, will be entitled to specific performance of its rights under this Warrant. The Company agrees that monetary damages would not be adequate compensation for any loss incurred by reason of a breach by it of the provisions of this Warrant and
hereby agrees to waive and not to assert the defense in any action for specific performance that a remedy at law would be adequate. 

k) Successors and Assigns. Subject to applicable securities laws, this Warrant and the rights and obligations evidenced
hereby shall inure to the benefit of and be binding upon the successors and permitted assigns of the Company and the successors and permitted assigns of Holder. The provisions of this Warrant are intended to be for the benefit of any Holder from
time to time of this Warrant and shall be enforceable by the Holder or holder of Warrant Shares. 

  
 12 

 l) Amendment. This Warrant may be modified or amended or the provisions
hereof waived with the written consent of the Company and the holders of a majority of the Warrant Shares underlying the then outstanding warrants issued under the Second Securities Purchase Agreement. Any amendment effected in the accordance with
the foregoing shall be binding on all Warrants and holders thereof. 
 m) Severability. Wherever possible, each
provision of this Warrant shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Warrant shall be prohibited by or invalid under applicable law, such provision shall be ineffective to the
extent of such prohibition or invalidity, without invalidating the remainder of such provisions or the remaining provisions of this Warrant. 

n) Headings. The headings used in this Warrant are for the convenience of reference only and shall not, for any purpose,
be deemed a part of this Warrant.

 NOTICE OF EXERCISE 

 

	TO:	PSIVIDA CORP. 

 (1) The undersigned hereby elects to purchase ________ Warrant Shares of
the Company pursuant to the terms of the attached Warrant (only if exercised in full), and tenders herewith payment of the exercise price in full, together with all applicable transfer taxes, if any.

 APPENDIX A 

Black-Scholes Option Pricing formula to be used when calculating the value of each new warrant to purchase one share in the Acquirer shall be: 

CAcq = SAcqe-l(TAcq-tAcq)N(d1)
– KAcqe-r(TAcq-tAcq)N(d2), where 

CAcq = value of each warrant to purchase one share in the Acquirer 

SAcq = price of Acquirer’s stock as determined by reference to the average of
the closing prices on the securities exchange or Nasdaq over the 20-day period ending three trading days prior to the closing of the Acquisition described in Section 3(d) if the Acquirer’s
stock is then traded on such exchange or system, or the average of the closing bid or sale prices (whichever is applicable) in the over-the-counter market over the 20-day period ending three trading days prior to the closing of the Acquisition if the Acquirer’s stock is then actively traded in the
over-the-counter market, or the then most recently completed financing if the Acquirer’s stock is not then traded on a securities exchange or system or in the over-the-counter market. 

TAcq = expiration date of new warrants to purchase shares in the Acquirer = TCorp 
 tAcq = date of
issue of new warrants to purchase shares in the Acquirer 
 TAcq-tAcq = time until warrant expiration, expressed in years 
 s = volatility = annualized standard deviation of daily log-returns (using a 262-day annualization factor) of the
Acquirer’s stock price on the securities exchange or Nasdaq over a 20-day trading period, determined by the Warrant Holders, that is within the 100-day trading
period ending on the trading day immediately after the public announcement of the Acquisition described in Section 3(d) if the Acquirer’s stock is then traded on such exchange or system, or the annualized standard deviation of daily-log returns (using a 262-day annualization factor) of the closing bid or sale prices (whichever is applicable) in the over-the-counter market over a 20-day trading period, determined by the Warrant Holder, that is within the 100-day trading
period ending on the trading day immediately after the public announcement of the Acquisition if the Acquirer’s stock is then actively traded in the
over-the-counter market, or 0.5 (or 50%) if the Acquirer’s stock is not then traded on a securities exchange or system or in the over-the-counter market. In no event will the volatility variable be more than 0.5 (or 50%).

CCorp = value of each Warrant to purchase one Common Share in the Company 

SCorp = price of Company stock as determined by reference to the average of the
closing prices on Nasdaq over the 20-day period ending three trading days prior to the closing of the Acquisition if the Company’s stock is then traded on Nasdaq, or the average of the closing bid or sale
prices (whichever is applicable) in the over-the-counter market over the 20-day period ending three trading days prior to the
closing of the Acquisition if the Company’s stock is then actively traded in the over-the-counter market, or on the AIM market, if the Company’s stock is not
then traded on a securities exchange or system or in the over-the-counter market, or the most recently completed financing if the Company’s stock is not then traded
on AIM. 
 TCorp = expiration date of Warrants to purchase shares in the Company

 tCorp = date of public announcement of transaction 

TCorp-tCorp
= time until Warrant expiration, expressed in years  
 s = volatility = the
annualized standard deviation of daily log-returns (using a 262-day annualization factor) of the Company’s stock price on the securities exchange or Nasdaq Global
Select Market over a 20-day trading period, determined by the Warrant Holders, that is within the 100-day trading period ending on the trading day immediately
after the public announcement of the Acquisition if the Company’s stock is then traded on such exchange or system, or the annualized standard deviation of daily-log returns (using a 262-day annualization factor) of the closing bid or sale prices (whichever is applicable) in the over-the-counter market over a 20-day trading period, determined by the Warrant Holder, that is within the 100-day trading period ending on the trading day immediately after the public announcement of the
Acquisition if the Company’s stock is then actively traded in the over-the-counter market, or 0.5 (or 50%) if the Company’s stock is not then traded on a

Section 3.1.2 Limitation on Demand Registrations. The Company shall not be obligated to take any action to effect any Demand
Registration if a Demand Registration was declared effective, the Investors withdraw their request pursuant to Section 3.1.3 or an Underwritten Shelf Takedown requested by the Investors was consummated within the preceding ninety
(90) days.

Securities included in a Demand Registration from such Demand Registration at any time prior to the effectiveness of the applicable Demand Registration Statement. Upon receipt of a notice to such effect from the Investor or Investors holding an

delivered in connection with sales of Registrable Securities by an underwriter or dealer. 
 Section 3.1.5 Delay in Filing;
Suspension of Registration. If the filing, initial effectiveness or continued use of a Demand Registration Statement at any time would require the Company to make an Adverse Disclosure, the Company may, upon giving prompt written notice of such

Rule 415 under the Securities Act (“Shelf Registration Statement”) relating to the offer and sale of Registrable Securities held by the Investors from time to time hereunder and under the First Registration Rights Agreement (but
only to the extent such securities have not been registered pursuant to the First Registration Rights Agreement) in accordance with the methods of distribution elected by the Investors, and the Company shall use its commercially reasonable efforts
to cause such Shelf Registration Statement to promptly become effective under the Securities Act, but in no event later than sixty (60) days after filing such Shelf Registration Statement. Any such Registration pursuant to this
Section 3.2.1(a) shall hereinafter be referred to as a “Shelf Registration.” 
 (b) If on the date of the Closing, the
Company is not a WKSI, then the Investors shall submit a written notice to the Company specifying the aggregate amount of Registrable Securities to be registered, which shall not be less than a majority of the then outstanding Registrable Securities
held by the Investors. The Company shall provide to the Investors the information necessary to determine the Company’s status as a WKSI upon request. 

Section 3.2.2 Continued Effectiveness. The Company shall use its commercially reasonable efforts to keep such Shelf Registration
Statement continuously effective under the Securities Act in order to permit the Prospectus forming part of the Shelf Registration Statement to be usable by an Investor until the earlier of: (i) the date as of which all Registrable Securities
have been sold pursuant to the Shelf Registration Statement or another Registration Statement filed under the Securities Act (but in no event prior to the applicable period referred to in Section 4(a)(3) of the Securities Act and Rule 174

commercially reasonable efforts to keep the Shelf Registration Statement effective during the Shelf Period if the Company voluntarily takes any action or omits to take any action that would result in the Investors not being able to offer and sell
any Registrable Securities pursuant to such Shelf Registration Statement during the Shelf Period, unless such action or omission is required by applicable law. 

Section 3.2.3 Suspension of Registration. If the continued use of such Shelf Registration Statement at any time would require the
Company to make an Adverse Disclosure, the Company may, upon giving prompt written notice of such action to the Investors, suspend use of the Shelf Registration Statement (a “Shelf Suspension”); provided, however, that
the Company shall not be permitted to exercise a Shelf Suspension more than one time during any twelve (12)-month period for a period not to exceed sixty (60) days. In the case of a Shelf Suspension, the Investors agree to suspend use of the
applicable Prospectus in connection with 

  
 7 

 
any sale or purchase of, or offer to sell or purchase, Registrable Securities, upon receipt of the notice referred to above. The Company shall immediately notify the Investors in writing upon the
termination of any Shelf Suspension, amend or supplement the Prospectus, if necessary, so it does not contain any untrue statement or omission and furnish to the Investors such numbers of copies of the Prospectus as so amended or supplemented as the
Investors may reasonably request. The Company shall, if necessary, supplement or amend the Shelf Registration Statement, if required by the registration form used by the Company for the Shelf Registration Statement or by the instructions applicable
to such registration form or by the Securities Act or the rules or regulations promulgated thereunder or as may reasonably be requested by the Investors. 

Section 3.2.4 Shelf Takedown. 

(a) At any time the Company has an effective Shelf Registration Statement with respect to the Investors’ Registrable Securities, by
notice to the Company specifying the intended method or methods of disposition thereof, the Investors may make a written request (a “Shelf Takedown Request”) to the Company to effect a Public Offering, including an Underwritten
Shelf Takedown, of all or a portion of the Investors’ Registrable Securities that may be registered under such Shelf Registration Statement, and as soon as practicable the Company shall amend or supplement the Shelf Registration Statement as
necessary for such purpose. 
 (b) All determinations as to whether to complete any Underwritten Shelf Takedown and as to the timing,
manner, price and other terms of any Underwritten Shelf Takedown contemplated by this Section 3.2.4 shall be determined by the Investors. 

(c) The Company shall not be obligated to take any action to effect any Underwritten Shelf Takedown if (x) the anticipated net proceeds
from the Registrable Securities to be sold are not at least $5,000,000, or (y) a Demand Registration was declared effective or an Underwritten Shelf Takedown requested by the Investors was consummated within the preceding ninety (90) days.

 Section 3.3 Piggyback Registration. 

Section 3.3.1 Participation. If the Company at any time proposes to file a Registration Statement under the Securities Act or to
conduct a Public Offering under an effective Shelf Registration Statement with respect to any offering of its equity securities for its own account or for the account of any other Persons (other than (i) a Registration under Sections 3.1 or
3.2, (ii) a Registration on Form S-4 or Form S-8 or any successor form to such forms or (iii) a Registration of securities solely relating to an offering and sale
to employees or directors of the Company or its subsidiaries pursuant to any employee stock plan or other employee benefit plan arrangement), then, as soon as practicable (but in no event less than ten (10) Business Days prior to the proposed
date of filing of such Registration Statement or, in the case of a Public Offering under a Shelf Registration Statement, the anticipated pricing or trade date), the Company shall give written notice (a “Piggyback Notice”) of such
proposed filing or Public Offering to the Investors, and such Piggyback Notice shall offer the Investors the opportunity to register under such Registration Statement such number of Registrable Securities as the Investors

  
 8 

 
may request in writing, or to sell in such Public Offering up to such number of Registrable Securities that are included in the Shelf Registration Statement for such Public Offering or under a
Shelf Registration Statement filed pursuant to Section 3.2, (a “Piggyback Registration”). The Investors must notify the Company of the number of Registrable Securities that they are requesting to be included in the Registration
Statement within five (5) Business Days after receipt by the Investor of the Piggyback Notice. Subject to Section 3.3.2, the Company shall include in such Registration Statement or in such Public Offering as applicable, all such
Registrable Securities that are requested to be included therein within five (5) Business Days after receipt by the Investor of any such Piggyback Notice; provided, however, that if at any time after giving written notice of its
intention to register or sell any securities and prior to the effective date of the Registration Statement filed in connection with such Registration, or the pricing or trade date of a Public Offering under a Shelf Registration Statement, the
Company determines for any reason not to register or sell or to delay the Registration or sale of such securities, the Company shall give written notice of such determination to the Investors and, thereupon, (i) in the case of a determination
not to register or sell, shall be relieved of its obligation to register or sell any Registrable Securities in connection with such Registration or Public Offering (but not from its obligation to pay the Registration Expenses in connection
therewith), without prejudice, however, to the rights of any Investor to request that such Registration or sale be effected as a Demand Registration under Section 3.1 or an Underwritten Shelf Takedown under Section 3.2, as the case may be,
and (ii) in the case of a determination to delay Registration or sale, in the absence of a request for a Demand Registration or an Underwritten Shelf Takedown, as the case may be, shall be permitted to delay registering or selling any
Registrable Securities, for the same period as the delay in registering or selling such other securities as reasonably determined by the Company. The Investors shall have the right to withdraw all or part of their request for inclusion of its
Registrable Securities in a Piggyback Registration by giving written notice to the Company of its request to withdraw. 
 Section 3.3.2
Priority of Piggyback Registration. If the managing underwriter or underwriters of any proposed offering of Registrable Securities included in a Piggyback Registration informs the Company and the Investors in writing that, in its or their
opinion, the aggregate number of securities that the Investors and any other Persons intend to include in such offering exceeds the number that can be sold in such offering without being likely to have a significant adverse effect on the price,
timing or distribution of the securities offered or the market for the securities offered, then the securities to be included in such Registration shall be (i) first, one hundred percent (100%) of the securities that the Company proposes to
sell, and (ii) second, and only if all the securities referred to in clause (i) have been included, the number of the Investors’ Registrable Securities and the registrable securities of any Person included in such Piggyback

the sellers thereof set forth in such Registration Statement; 
 (c) notify the Investors and the managing underwriter or underwriters, if
any, and (if requested) confirm such notice in writing and provide copies of the relevant documents, as soon as reasonably practicable after notice thereof is received by the Company (a) when the applicable Registration Statement or any

comfort letters as the managing underwriter or underwriters reasonably request, dated the date of execution of the underwriting agreement and brought down to the closing under the underwriting agreement;

 (w) take no direct or indirect action prohibited by
Regulation M under the Exchange Act; 
 (x) take all reasonable action to ensure that any Issuer Free Writing Prospectus utilized in
connection with any Registration complies in all material respects with the Securities Act, is filed in accordance with the Securities Act to the extent required thereby, is retained in accordance with the Securities Act to the extent required
thereby and, when taken together with the related Prospectus, will not contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in light of the circumstances under which they were
made, not misleading; and 
 (y) take all such other commercially reasonable actions as are necessary or advisable in order to expedite or
facilitate the disposition of such Registrable Securities in accordance with the terms of this Agreement. 
 Section 3.5.2 Company
Information Requests. The Company may require the Investors to furnish to the Company such information regarding the distribution of such securities and such other information relating to the Investors and their ownership of Registrable
Securities as the Company may from time to time reasonably request in writing and the Company may exclude from such Registration or sale the Registrable Securities of each Investor who unreasonably fails to furnish such information within a
reasonable time after receiving such request. Each Investor shall furnish such information to the Company and to cooperate with the Company as reasonably necessary to enable the Company to comply with the provisions of this Agreement. 

Section 3.6 Underwritten Offerings. 

Section 3.6.1 Shelf and Demand Registrations. If requested by the underwriters for any Underwritten Public Offering, pursuant to a
registration or sale under Sections 3.1 or 3.2, the Company shall enter into an underwriting agreement with such underwriters, such agreement to be reasonably satisfactory in substance and form to each of the Company, the Investors and the
underwriters, and to contain such representations and warranties by the Company and such other terms as are generally prevailing in agreements of that type, including indemnities no less favorable to the recipient thereof than those provided in
Section 3.9 of this Agreement. Each Investor shall cooperate with the Company in the negotiation of the underwriting agreement and shall give consideration to the reasonable suggestions of the Company regarding the form thereof, and each
Investor shall complete and execute all questionnaires, powers of attorney and other documents reasonably requested by the underwriters and required under the terms of such underwriting arrangements. No Investor shall be required to make any
representations or warranties to or agreements with the Company or the underwriters other than representations, warranties or agreements regarding such Investor’s title to the Registrable Securities, intended

  
 14 

 
method of distribution and any other representations to be made by such Investor as are generally prevailing in agreements of that type, and the aggregate amount of the liability of any Investor
under such agreement shall not exceed such Investor’s proceeds from the sale of their Registrable Securities in the offering, net of underwriting discounts and commissions but before expenses. 

Section 3.6.2 Piggyback Registrations. If the Company proposes to register or sell any of its securities under the Securities Act
as contemplated by Section 3.3 and such securities are to be distributed through one or more underwriters, the Company shall, if requested by the Investors pursuant to Section 3.3 and, subject to the provisions of Section 3.3.2, use
its commercially reasonable efforts to arrange for such underwriters to include on the same terms and conditions that apply to the other sellers in such Registration or sale all the Registrable Securities to be offered and sold by such Investors
among the securities of the Company to be distributed by such underwriters in such Registration or sale. The Investors shall be party to the underwriting agreement between the Company and such underwriters and shall complete and execute all
questionnaires, powers of attorney and other documents reasonably requested by the underwriters and required under the terms of such underwriting arrangements. No Investor shall be required to make any representations or warranties to or agreements
with the Company or the underwriters other than representations, warranties or agreements regarding such Investor’s title to the Registrable Securities, intended method of distribution and any other representations to be made by such Investor
as are generally prevailing in agreements of that type, and the aggregate amount of the liability of any Investor shall not exceed such Investor’s proceeds from the sale of its Registrable Securities in the offering, net of underwriting
discounts and commissions but before expenses. 
 Section 3.6.3 Selection of Underwriters; Selection of Counsel. In the case of
an Underwritten Public Offering under Sections 3.1 or 3.2, the managing underwriter or underwriters to administer the offering shall be determined by the Investors holding at least a majority of the then outstanding Registrable Securities included
in such registration. In the case of an Underwritten Public Offering under Section 3.3, the managing underwriter or underwriters to administer the offering shall be determined by the Company; provided that such underwriter or
underwriters shall be reasonably acceptable to such Investors. 
 Section 3.7 No Inconsistent Agreements; Additional Rights.
Neither the Company nor any of its subsidiaries shall hereafter enter into, and neither the Company nor any of its subsidiaries is currently a party to, any agreement with respect to its securities that is inconsistent with the rights granted to the
Investors by this Agreement. Without approval of the Investors, neither the Company nor any of its subsidiaries shall enter into any agreement granting registration or similar rights to any Person (other than respect to registration rights granted
pursuant to the First Registration Rights Agreement and the SWK Warrants), and the Company hereby represents and warrants that, as of the date hereof, no registration or similar rights have been granted to any other Person other than pursuant to
this Agreement, the First Registration Rights Agreement and the SWK Warrants.

All such expenses are referred to herein as “Registration Expenses”. The Company shall not be required to pay any
fees and disbursements to underwriters not customarily paid by the issuers of securities in an offering similar to the applicable offering, including underwriting discounts and commissions and transfer taxes, if any, attributable to the sale of

 Section 3.9 Indemnification. 

Section 3.9.1 Indemnification by the Company. The Company shall indemnify and hold harmless, to the full extent permitted by law,
each Investor, each shareholder, member, limited or general partner of any Investor, each shareholder, member, limited or general partner of each such shareholder, member, limited or general partner, each of their respective Affiliates, officers,
directors, shareholders, employees, advisors, and agents and each Person who controls (within the meaning of the Securities Act or the Exchange Act) such Persons and each of their respective Representatives from and against any and all losses,
penalties, judgments, suits, costs, claims, damages, liabilities and expenses, joint or several (including reasonable costs of investigation and legal expenses as incurred and any indemnity and contribution payments made to underwriters ) (each, a
“Loss” and collectively “Losses”) arising out of or based upon (i) any untrue or alleged untrue statement of a material fact contained in any Registration Statement under which 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 or any of its subsidiaries including any report and other document filed under the Exchange Act, (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 or (iii) any violation or alleged violation by the Company or any of its
subsidiaries of any federal, state, foreign or common law rule or regulation 

  
 16 

 
applicable to the Company or any of its subsidiaries and relating to action or inaction in connection with any such registration, disclosure document or other document or report; provided,
that the Investors shall not be entitled to indemnification pursuant to this Section 3.9.1 in respect of any untrue statement or omission contained in any information relating to any Investor furnished in writing by such Investor to the Company
specifically for inclusion in a Registration Statement and used by the Company in conformity therewith (such information “Selling Stockholder Information”). This indemnity shall be in addition to any liability the Company may
otherwise have. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of the Investors or any indemnified party and shall survive the Transfer of such securities by any Investor and regardless of
any indemnity agreed to in the underwriting agreement that is less favorable to the Investors. The Company shall also indemnify underwriters, selling brokers, dealer managers and similar securities industry professionals participating in the
distribution, their officers and directors and each Person who controls such Persons (within the meaning of the Securities Act and the Exchange Act) to the same extent as provided above (with appropriate modification) with respect to the
indemnification of the indemnified parties. 
 Section 3.9.2 Indemnification by the Investors. Each Investor shall (severally
and not jointly) indemnify and hold harmless, to the fullest extent permitted by law, the Company, its directors and officers and each Person who controls the Company (within the meaning of the Securities Act or the Exchange Act) from and against
any Losses resulting from (i) any untrue statement of a material fact in any Registration Statement under which 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, but only to the extent, that such untrue statement or omission is contained in such
Investor’s Selling Stockholder Information. In no event shall the liability of any Investor hereunder be greater in amount than the dollar amount of the proceeds from the sale of its Registrable Securities in the offering giving rise to such
indemnification obligation, net of underwriting discounts and commissions but before expenses, less any amounts paid by such Investor pursuant to Section 3.9.4 and any amounts paid by such Investor as a result of liabilities incurred under the
underwriting agreement, if any, related to such sale. 
 Section 3.9.3 Conduct of Indemnification Proceedings. Any Person
entitled to indemnification hereunder shall (i) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification (provided that any delay or failure to so notify the indemnifying party
shall relieve the indemnifying party of its obligations hereunder only to the extent, if at all, that it forfeits substantive legal rights by reason of such delay or failure) and (ii) permit such indemnifying party to assume the defense of such
claim with counsel reasonably satisfactory to the indemnified party; provided, however, that any Person entitled to indemnification hereunder shall have the right to select and employ separate counsel and to participate in the defense
of such claim, but the fees and expenses of such counsel shall be at the expense of such Person unless (i) the indemnifying party has agreed in writing to pay such fees or expenses, (ii) the indemnifying party shall have failed to assume
the defense of such claim within a reasonable time after receipt of notice of such claim from the Person entitled to 

  
 17 

 
indemnification hereunder and employ counsel reasonably satisfactory to such Person, (iii) the indemnified party has reasonably concluded (based upon advice of its outside counsel) that
there may be legal defenses available to it or other indemnified parties that are different from or in addition to those available to the indemnifying party, or (iv) in the reasonable judgment of any such Person (based upon advice of its
outside counsel) a conflict of interest may exist between such Person and the indemnifying party with respect to such claims (in which case, if the Person notifies the indemnifying party in writing that such Person elects to employ separate counsel
at the expense of the indemnifying party, the indemnifying party shall not have the right to assume the defense of such claim on behalf of such Person). If the indemnifying party assumes the defense, the indemnifying party shall not have the right
to settle such action without the consent of the indemnified party, which shall not be unreasonably withheld, conditioned or delayed. No indemnifying party shall consent to entry of any judgment or enter into any settlement which does not include as
an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of an unconditional release from all liability in respect to such claim or litigation without the prior written consent of such indemnified party. 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, but such consent may not be unreasonably withheld, conditioned or delayed.
It is understood that the indemnifying party or parties shall not, except as specifically set forth in this Section 3.9.3, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the reasonable fees,
disbursements or other charges of more than one separate firm admitted to practice in such jurisdiction at any one time unless (x) the employment of more than one counsel has been authorized in writing by the indemnifying party or parties,
(y) an indemnified party has reasonably concluded (based on the advice of counsel) that there may be legal defenses available to it that are different from or in addition to those available to the other indemnified parties or (z) a
conflict or potential conflict exists or may exist (based upon advice of counsel to an indemnified party) between such indemnified party and the other indemnified parties, in each of which cases the indemnifying party shall be obligated to pay the
reasonable fees and expenses of such additional counsel or counsels. 
 Section 3.9.4 Contribution. If for any reason the
indemnification provided for in Section 3.9.1 and Section 3.9.2 is unavailable to an indemnified party or insufficient in respect of any Losses referred to therein (other than as a result of exceptions or limitations on indemnification
contained in Section 3.9.1 and Section 3.9.2), then the indemnifying party shall contribute to the amount paid or payable by the indemnified party as a result of such Loss in such proportion as is appropriate to reflect the relative fault
of the indemnifying party on the one hand and the indemnified party or parties on the other hand in connection with the acts, statements or omissions that resulted in such Losses, as well as any other relevant equitable considerations. In connection
with any Registration Statement filed with the SEC by the Company, the relative fault of the indemnifying party on the one hand and the indemnified party on the other hand shall be determined by reference to, among other things, whether any untrue
or alleged untrue statement of a material fact or the omission or alleged 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. The parties hereto agree that it would not be just or equitable if contribution pursuant to this Section 3.9.4 were determined by pro rata
allocation or by any other method of allocation that does not take account of the equitable considerations referred to in this 

  
 18 

 
Section 3.9.4. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who was not
guilty of such fraudulent misrepresentation. The amount paid or payable by an indemnified party as a result of the Losses referred to in Sections 3.9.1 and 3.9.2 shall be deemed to include, subject to the limitations set forth above, any legal or
other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 3.9.4, in connection with any Registration Statement filed by
the Company, no Investor shall not be required to contribute any amount in excess of the dollar amount of the proceeds from the sale of its Registrable Securities in the offering giving rise to such indemnification obligation, net of underwriting
discounts and commissions but before expenses, less any amounts paid by such Investor pursuant to Section 3.9.2 and any amounts paid by such Investor as a result of liabilities incurred under the underwriting agreement, if any, related to such
sale. If indemnification is available under this Section 3.9, the indemnifying parties shall indemnify each indemnified party to the full extent provided in Sections 3.9.1 and 3.9.2 hereof without regard to the provisions of this
Section 3.9.4. The remedies provided for in this Section 3.9 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity. 

Section 3.10 Rules 144 and 144A and Regulation S. The Company shall file the reports required to be filed by it under the
Securities Act and the Exchange Act and the rules and regulations adopted by the SEC thereunder (or, if the Company is not required to file such reports, it will, upon the request of any Investor, make publicly available such necessary information
for so long as necessary to permit sales that would otherwise be permitted by this Agreement pursuant to Rule 144, Rule 144A or Regulation S under the Securities Act, as such rules may be amended from time to time or any similar rule or regulation
hereafter adopted by the SEC), and it will take such further action as any Investor may reasonably request, all to the extent required from time to time to enable the Investors to sell Registrable Securities without Registration under the Securities
Act in transactions that would otherwise be permitted by this Agreement and within the limitation of the exemptions provided by (i) Rule 144, Rule 144A or Regulation S under the Securities Act, as such rules may be amended from time to time, or
(ii) any similar rule or regulation hereafter adopted by the SEC. Upon the request of any Investor, the Company will deliver to the Investors a written statement as to whether it has complied with such requirements and, if not, the specifics
thereof. 
 Section 3.11 Existing Registration Statements. Notwithstanding anything herein to the contrary and subject to
applicable law and regulation, the Company may satisfy any obligation hereunder to file a Registration Statement or to have a Registration Statement become effective by a specified date by designating, by notice to each Investor, a Registration
Statement that previously has been filed with the SEC or become effective, as the case may be, as the relevant Registration Statement for purposes of satisfying such obligation, and all references to any such obligation shall be construed
accordingly; provided that such previously filed Registration Statement may be, and is, amended or, subject to applicable securities laws, supplemented to add the number of Registrable Securities, and, to the extent necessary, to identify the
Investors as selling stockholders demanding the filing of a Registration Statement pursuant to the terms of this Agreement. To the extent this Agreement refers to the filing or effectiveness of other Registration Statements, by or at a specified
time and the Company has, in lieu of then filing such Registration Statements or having such Registration Statements become effective, 

  
 19 

 
designated a previously filed or effective Registration Statement as the relevant Registration Statement for such purposes, in accordance with the preceding sentence, such references shall be
construed to refer to such designated Registration Statement, as amended or supplemented in the manner contemplated by the immediately preceding sentence.

representatives, successors and permitted assigns. Except as otherwise expressly provided herein, neither the Investors nor any other party hereto may assign any of its respective rights or delegate any of its respective obligations under this

 EW Healthcare
Partners, L.P. 
 EW Healthcare Partners-A, L.P. 

21 Waterway Avenue, Suite 255 
 The Woodlands, TX 77380 

Ladies and Gentlemen: 
 As an inducement to the
purchasers listed above (the “Purchasers”) to execute the Securities Purchase Agreement (the “Purchase Agreement”) among the Purchasers and pSivida Corp. (the “Company”) providing for
an initial investment (the “Investment”) in shares of common stock (the “Common Stock”) of the Company, the undersigned, by executing this lock-up agreement
(this “Agreement”), agrees that without, in each case, the prior written consent of the Purchasers holding a majority of the shares of Common Stock purchased pursuant to the Purchase Agreement, during the period specified in
the second succeeding paragraph (the “Lock-Up Period”), the undersigned will not: (1) offer, pledge, announce the intention to sell, sell, contract to sell, sell any option or
contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, make any short sale or otherwise transfer or dispose of, directly or indirectly, any shares of Common Stock or any securities convertible
into, exercisable or exchangeable for or that represent the right to receive Common Stock (including without limitation, Common Stock which may be deemed to be beneficially owned by the undersigned in accordance with the rules and regulations of the
Securities and Exchange Commission and securities which may be issued upon exercise of a stock option or warrant), whether now owned or hereafter acquired (the “Undersigned’s Securities”); (2) enter into any swap or other
agreement that transfers, in whole or in part, any of the economic consequences of ownership of the Undersigned’s Securities, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Common Stock or
such other securities, in cash or otherwise; (3) make any demand for, or exercise any right with respect to, the registration of any Common Stock or any security convertible into or exercisable or exchangeable for Common Stock; or
(4) publicly disclose the intention to do any of the foregoing. 
 The undersigned agrees that the foregoing restrictions preclude the
undersigned from engaging in any hedging or other transaction which is designed to or which reasonably could be expected to lead to or result in a sale or disposition of the Undersigned’s Securities even if the Undersigned’s Securities
would be disposed of by someone other than the undersigned. Such prohibited hedging or other transactions would include, without limitation, any short sale or any purchase, sale or grant of any right (including, without limitation, any put or call
option) with respect to any of the Undersigned’s Securities or with respect to any security that includes, relates to or derives any significant part of its value from the Undersigned’s Securities. 

The Lock-Up Period will commence on the date of this Agreement and continue and include the date that
is the earlier of (a) the date of the closing of the transactions contemplated by the Second Securities Purchase Agreement (the “Second Securities Purchase Agreement”) by and among the Company and the investors signatory
thereto dated the date hereof (the “Additional Investment”) and (b) the date of the Company’s first meeting of stockholders at which a proposal to approve the Additional Investment is not approved by the Company’s
stockholders. The Company will provide the undersigned with written notice confirming the expiration of the Lock-Up Period. 

 Notwithstanding the foregoing, the undersigned may transfer the Undersigned’s Securities:
(i) as a bona fide gift or gifts; (ii) to the immediate family of the Undersigned or any trust, partnership, limited liability company or other entity for the direct or indirect benefit of the undersigned or the immediate family of
the undersigned; or (iii) by testate succession or intestate succession; provided, in the case of clauses (i)-(iii), that (x) such transfer shall not involve a disposition for value, (y) the transferee agrees in writing with
the Purchasers to be bound by the terms of this Agreement and (z) no filing by any party under Section 16(a) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), shall be required or shall be made
voluntarily in connection with such transfer (other than a filing on a Form 5 filed within 45 days of December 31, 2018, in which case such Form 5 shall include a footnote describing the transaction being reported). For purposes of this
Agreement, “immediate family” shall mean any relationship by blood, marriage, domestic partnership or adoption, not more remote than first cousin. Additionally, any Common Stock acquired by the undersigned in the open market on or after
the date of the Purchase Agreement will not be subject to this Agreement; provided no filing under Section 16(a) of the Exchange Act by any party shall be voluntarily made in connection with any subsequent sale, transfer, gift or
disposition of such Common Stock. 
 In addition, the foregoing restrictions shall not apply to: 

(i) the exercise of stock options granted pursuant to the Company’s equity incentive plans (including by “net” or “cashless
exercise”) or warrants that are described in the Company’s Exchange Act reports; provided that the terms of this Agreement shall apply to any of the Undersigned’s Securities issued upon such exercise; 

(ii) transfers of the Undersigned’s Securities to the Company as forfeitures to satisfy tax withholding obligations pursuant to the
Company’s equity incentive plans or inducement awards that are described in the Company’s Exchange Act reports; 
 (iii) transfers
of the Undersigned’s Securities to the Company by an executive officer or director upon death, disability or termination of employment or service, in each case, of such executive officer or director, as applicable; 

(iv) transfers of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock pursuant to a bona fide
third-party tender offer, merger, consolidation or other similar transaction made to all holders of the Company’s capital stock involving a change of control of the Company; provided that in the event that such tender offer, merger,
consolidation or other such transaction is terminated and the Undersigned’s Securities are returned to the Undersigned, the Undersigned’s Securities shall again be subject to the restrictions contained in this Agreement; 

 (v) transfers of Common Stock or any securities convertible into or exercisable or exchangeable
for Common Stock by operation of law to a spouse, former spouse, domestic partner, former domestic partner, child or other dependent pursuant to a qualified domestic order or in connection with a divorce settlement; provided that the
transferee agrees in writing to be bound by the terms of this Agreement prior to such transfer and, if the undersigned is required to file a report under Section 16(a) of the Exchange Act reporting a reduction in beneficial ownership of shares
of Common Stock during the Lock-Up Period, that the undersigned shall include a statement in such report to the effect that the transfer occurred by operation of law, such as pursuant to a qualified domestic
order or in connection with a divorce settlement, as applicable; 
 (vi) the establishment of any contract, instruction or plan (a
“Plan”) that satisfies all of the requirements of Rule 10b5-1(c)(1)(i)(B) under the Exchange Act (“Rule 10b5-1”); provided that
no sales of the Undersigned’s Securities shall be made pursuant to such a Plan prior to the expiration of the Lock-Up Period, and such a Plan may only be established if no public announcement of the
establishment or existence thereof and no filing with the Securities and Exchange Commission or other regulatory authority in respect thereof or transactions thereunder or contemplated thereby, by the undersigned, the Company or any other person,
shall be required, and no such announcement or filing is made voluntarily, by the undersigned, the Company or any other person, prior to the expiration of the Lock-Up Period; or 

(vii) the sale or disposal of shares of Common Stock pursuant to a Plan that satisfies all of the requirements of Rule 10b5-1 and that is in effect as of the date of the Purchase Agreement; provided if the undersigned is required to file a report under Section 16(a) of the Exchange Act reporting a reduction in beneficial
ownership of shares of Common Stock during the Lock-Up Period, the undersigned shall include a statement in such report to the effect that the transfer was made pursuant to a Plan established to comply with
Rule 10b5-1. 
 In furtherance of the foregoing, the Company and its transfer agent and registrar
are hereby authorized to decline to make any transfer of shares of Common Stock if such transfer would constitute a violation or breach of this Agreement. 

The undersigned hereby represents and warrants that the undersigned has full power and authority to enter into this Agreement. All authority
herein conferred or agreed to be conferred and any obligations of the undersigned shall be binding upon the successors, assigns, heirs or personal representatives of the undersigned. 

The undersigned understands that the undersigned shall be released from all obligations under this Agreement if (i) the Company notifies

 Section 3.1.3 Demand Withdrawal. The Investors may withdraw all or any portion of
their Registrable Securities included in a Demand Registration from such Demand Registration at any time prior to the effectiveness of the applicable Demand Registration Statement. Upon receipt of a notice to such effect from the Investor or

the rules or regulations promulgated thereunder or as may reasonably be requested by the Investors.

or 3.2, (ii) a Registration on Form S-4 or Form S-8 or any successor form to such forms or (iii) a Registration of securities solely relating to an offering and sale to employees or directors of the Company or its subsidiaries pursuant

a Public Offering under a Shelf Registration Statement, the anticipated pricing or trade date), the Company shall give written notice (a “Piggyback Notice”) of such proposed filing or Public Offering to the Investors, and such
Piggyback Notice shall offer the Investors the opportunity to register under such Registration Statement such number of Registrable Securities as the Investors may request in writing, or to sell in such Public Offering up to such number of
Registrable Securities that are included in the Shelf Registration Statement for such Public Offering or under a Shelf Registration Statement filed pursuant to Section 3.2, (a “Piggyback Registration”). The Investors

filed in connection with such Registration, or the pricing or trade date of a Public Offering under a Shelf Registration Statement, the Company determines for any reason not to register or sell or to delay the Registration or sale of such
securities, the Company shall give written notice of such determination to the Investors and, thereupon, (i) in the case of a determination not to register or sell, shall be relieved of its obligation to register or sell any Registrable
Securities in connection with such Registration or Public Offering (but not from its obligation to pay the Registration Expenses in connection therewith), without prejudice, however, to the rights of any Investor to request that such Registration or
sale be effected as a Demand Registration under Section 3.1 or an Underwritten Shelf Takedown under Section 3.2, as the case may be, and (ii) in the case of a determination to delay Registration or sale, in the absence
of a request for a Demand Registration or an Underwritten Shelf Takedown, as the case may be, shall be permitted to delay registering or selling any Registrable Securities, for the same period as the delay in registering or selling such other
securities as reasonably determined by the Company. The Investors shall have the right to withdraw all or part of their request for inclusion of its Registrable Securities in a Piggyback Registration by giving written notice to the Company of its
request to withdraw. 
 Section 3.3.2 Priority of Piggyback Registration. If the managing underwriter or underwriters of
any proposed offering of Registrable Securities included in a Piggyback Registration informs the Company and the Investors in writing that, in its or their opinion, the aggregate number of securities that the Investors and any other Persons intend
to include in such offering exceeds the number that can be sold in such offering without being likely to have a significant adverse effect on the price, timing or distribution of the securities offered or the market for the securities offered, then
the securities to be included in such Registration shall be (i) first, one hundred percent (100%) of the securities that the Company proposes to sell, and (ii) second, and only if all the securities referred to in clause
(i) have been included, the number of the Investors’ Registrable Securities and the registrable securities of any Person included in such Piggyback Registration pursuant to the registration rights related to the Second Securities

Section 3.9 Indemnification. 

Section 3.9.1 Indemnification by the Company. The Company shall indemnify and hold harmless, to the full extent permitted by law,
the Investors, each shareholder, member, limited or general partner of any Investor, each shareholder, member, limited or general partner of each such shareholder, member, limited or general partner, each of their respective Affiliates, officers,
directors, shareholders, employees, advisors, and agents and each Person who controls (within the meaning of the Securities Act or the Exchange Act) such Persons and each of their respective Representatives from and against any and all losses,
penalties, judgments, suits, costs, claims, damages, liabilities and expenses, joint or several (including reasonable costs of investigation and legal expenses as incurred and any indemnity and contribution payments made to underwriters ) (each, a
“Loss” and collectively “Losses”) arising out of or based upon (i) any untrue or alleged untrue statement of a material fact contained in any Registration Statement under which 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 or any of its subsidiaries including any report and other document filed under the Exchange Act, (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 or (iii) any violation or alleged violation by the Company or
any of its subsidiaries of any federal, state, foreign or common law rule or regulation applicable to the Company or any of its subsidiaries and relating to action or inaction in connection with any such registration, disclosure document or other
document or report; provided, that the Investors shall not be entitled to indemnification pursuant to this Section 3.9.1 in respect of any untrue statement or omission contained in any information relating to any Investor furnished in
writing by such Investor to the Company specifically for inclusion in a 

  
 - 16 - 

 
Registration Statement and used by the Company in conformity therewith (such information “Selling Stockholder Information”). This indemnity shall be in addition to any liability
the Company may otherwise have. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of the Investors or any indemnified party and shall survive the Transfer of such securities by any Investor and
regardless of any indemnity agreed to in the underwriting agreement that is less favorable to the Investors. The Company shall also indemnify underwriters, selling brokers, dealer managers and similar securities industry professionals participating
in the distribution, their officers and directors and each Person who controls such Persons (within the meaning of the Securities Act and the Exchange Act) to the same extent as provided above (with appropriate modification) with respect to the
indemnification of the indemnified parties. 
 Section 3.9.2 Indemnification by the Investors. Each Investor shall (severally
and not jointly) indemnify and hold harmless, to the fullest extent permitted by law, the Company, its directors and officers and each Person who controls the Company (within the meaning of the Securities Act or the Exchange Act) from and against
any Losses resulting from (i) any untrue statement of a material fact in any Registration Statement under which 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, but only to the extent, that such untrue statement or omission is
contained in such Investor’s Selling Stockholder Information. In no event shall the liability of any Investor hereunder be greater in amount than the dollar amount of the proceeds from the sale of its Registrable Securities in the offering
giving rise to such indemnification obligation, net of underwriting discounts and commissions but before expenses, less any amounts paid by such Investor pursuant to Section 3.9.4 and any amounts paid by such Investor as a result of
liabilities incurred under the underwriting agreement, if any, related to such sale. 
 Section 3.9.3 Conduct of Indemnification
Proceedings. Any Person entitled to indemnification hereunder shall (i) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification (provided that any delay or failure to so notify the
indemnifying party shall relieve the indemnifying party of its obligations hereunder only to the extent, if at all, that it forfeits substantive legal rights by reason of such delay or failure) and (ii) permit such indemnifying party to assume the
defense of such claim with counsel reasonably satisfactory to the indemnified party; provided, however, that any Person entitled to indemnification hereunder shall have the right to select and employ separate counsel and to participate
in the defense of such claim, but the fees and expenses of such counsel shall be at the expense of such Person unless (i) the indemnifying party has agreed in writing to pay such fees or expenses, (ii) the indemnifying party shall have failed
to assume the defense of such claim within a reasonable time after receipt of notice of such claim from the Person entitled to indemnification hereunder and employ counsel reasonably satisfactory to such Person, (iii) the indemnified party has
reasonably concluded (based upon advice of its outside counsel) that there may be legal defenses available to it or other indemnified parties that are different from or in addition to those available to the indemnifying party, or (iv) in the
reasonable judgment of any such Person (based upon advice of its outside counsel) a conflict of interest may exist between 

  
 - 17 - 

 
such Person and the indemnifying party with respect to such claims (in which case, if the Person notifies the indemnifying party in writing that such Person elects to employ separate counsel at
the expense of the indemnifying party, the indemnifying party shall not have the right to assume the defense of such claim on behalf of such Person). If the indemnifying party assumes the defense, the indemnifying party shall not have the right to
settle such action without the consent of the indemnified party, which shall not be unreasonably withheld, conditioned or delayed. No indemnifying party shall consent to entry of any judgment or enter into any settlement which does not include as an
unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of an unconditional release from all liability in respect to such claim or litigation without the prior written consent of such indemnified party. 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, but such consent may not be unreasonably withheld, conditioned or delayed. It is
understood that the indemnifying party or parties shall not, except as specifically set forth in this Section 3.9.3, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the reasonable fees,
disbursements or other charges of more than one separate firm admitted to practice in such jurisdiction at any one time unless (x) the employment of more than one counsel has been authorized in writing by the indemnifying party or
parties, (y) an indemnified party has reasonably concluded (based on the advice of counsel) that there may be legal defenses available to it that are different from or in addition to those available to the other indemnified parties or
(z) a conflict or potential conflict exists or may exist (based upon advice of counsel to an indemnified party) between such indemnified party and the other indemnified parties, in each of which cases the indemnifying party shall be
obligated to pay the reasonable fees and expenses of such additional counsel or counsels. 
 Section 3.9.4 Contribution.
If for any reason the indemnification provided for in Section 3.9.1 and Section 3.9.2 is unavailable to an indemnified party or insufficient in respect of any Losses referred to therein (other than as a result of exceptions or
limitations on indemnification contained in Section 3.9.1 and Section 3.9.2), then the indemnifying party shall contribute to the amount paid or payable by the indemnified party as a result of such Loss in such proportion as
is appropriate to reflect the relative fault of the indemnifying party on the one hand and the indemnified party or parties on the other hand in connection with the acts, statements or omissions that resulted in such Losses, as well as any other
relevant equitable considerations. In connection with any Registration Statement filed with the SEC by the Company, the relative fault of the indemnifying party on the one hand and the indemnified party on the other hand shall be determined by
reference to, among other things, whether any untrue or alleged untrue statement of a material fact or the omission or alleged 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. The parties hereto agree that it would not be just or equitable if contribution pursuant to this
Section 3.9.4 were determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to in this Section 3.9.4. No Person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. The amount paid or payable by an
indemnified party as a result of the Losses referred to in Sections 3.9.1 and 3.9.2 shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such

  
 - 18 - 

 
indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 3.9.4, in connection with any Registration Statement
filed by the Company, no Investor shall not be required to contribute any amount in excess of the dollar amount of the proceeds from the sale of its Registrable Securities in the offering giving rise to such indemnification obligation, net of
underwriting discounts and commissions but before expenses, less any amounts paid by such Investor pursuant to Section 3.9.2 and any amounts paid by such Investor as a result of liabilities incurred under the underwriting agreement, if
any, related to such sale. If indemnification is available under this Section 3.9, the indemnifying parties shall indemnify each indemnified party to the full extent provided in Sections 3.9.1 and 3.9.2 hereof without regard to the
provisions of this Section 3.9.4. The remedies provided for in this Section 3.9 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity. 

Section 3.10 Rules 144 and 144A and Regulation S. The Company shall file the reports required to be filed by it under the
Securities Act and the Exchange Act and the rules and regulations adopted by the SEC thereunder (or, if the Company is not required to file such reports, it will, upon the request of any Investor, make publicly available such necessary information
for so long as necessary to permit sales that would otherwise be permitted by this Agreement pursuant to Rule 144, Rule 144A or Regulation S under the Securities Act, as such rules may be amended from time to time or any similar rule or regulation
hereafter adopted by the SEC), and it will take such further action as any Investor may reasonably request, all to the extent required from time to time to enable the Investors to sell Registrable Securities without Registration under the Securities
Act in transactions that would otherwise be permitted by this Agreement and within the limitation of the exemptions provided by (i) Rule 144, Rule 144A or Regulation S under the Securities Act, as such rules may be amended from time to time, or
(ii) any similar rule or regulation hereafter adopted by the SEC. Upon the request of any Investor, the Company will deliver to the Investors a written statement as to whether it has complied with such requirements and, if not, the specifics
thereof. 
 Section 3.11 Existing Registration Statements. Notwithstanding anything herein to the contrary and subject to
applicable law and regulation, the Company may satisfy any obligation hereunder to file a Registration Statement or to have a Registration Statement become effective by a specified date by designating, by notice to each Investor, a Registration
Statement that previously has been filed with the SEC or become effective, as the case may be, as the relevant Registration Statement for purposes of satisfying such obligation, and all references to any such obligation shall be construed
accordingly; provided that such previously filed Registration Statement may be, and is, amended or, subject to applicable securities laws, supplemented to add the number of Registrable Securities, and, to the extent necessary, to identify the
Investors as selling stockholders demanding the filing of a Registration Statement pursuant to the terms of this Agreement. To the extent this Agreement refers to the filing or effectiveness of other Registration Statements, by or at a specified
time and the Company has, in lieu of then filing such Registration Statements or having such Registration Statements become effective, designated a previously filed or effective Registration Statement as the relevant Registration Statement for such
purposes, in accordance with the preceding sentence, such references shall be construed to refer to such designated Registration Statement, as amended or supplemented in the manner contemplated by the immediately preceding sentence.
