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 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 

  
 12 








 
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

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 authority has taken, is taking or intends to take action to

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 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 

  
 13 








 
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. 

(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) 

  
 14 








 
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. 
 (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. 

  
 15 








 (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.

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, 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 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

 16 








 
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

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.

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


  
 17 








 
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. 

(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 issuance and sale of the Securities to the Purchasers will not trigger any
“change of control” or similar provision of any of the Company’s material contracts, agreements or other arrangements. 

  
 18 








 (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. The issuance of the Securities hereunder does not contravene the rules of the Principal Trading Market or the ASX.

the jurisdiction of its organization with the requisite corporate or partnership power and authority to enter into and to consummate the transactions contemplated by the Transaction Documents and carry out its obligations hereunder and thereunder.
The execution and delivery of this Agreement by such Purchaser and performance by such Purchaser of the transactions contemplated by this Agreement have been duly authorized by all necessary corporate or, if such Purchaser is not a corporation, such
partnership, limited liability company or other applicable similar action, on the part of such Purchaser. Each Transaction Document to which it is a party has been duly executed by such Purchaser, and when delivered by such Purchaser in
accordance with the terms hereof, will constitute the valid and legally binding obligation of such Purchaser, enforceable against it in accordance with its terms, except as such enforceability may be limited by applicable bankruptcy, insolvency,
reorganization, moratorium, liquidation or similar laws relating to, or affecting generally the enforcement of, creditors’ rights and remedies or by other equitable principles of general application. 

(b) No Conflicts. The execution, delivery and performance by such Purchaser of the Transaction Documents and the consummation by such
Purchaser of the transactions contemplated hereby and thereby will not result in a violation of the organizational documents of such Purchaser. 

(c) Investment Intent. Such Purchaser understands that the Securities are “restricted securities” and have not been
registered under the Securities Act or any applicable state securities law and is acquiring the Securities as principal for its own account and not with a view to, or for distributing or reselling such Securities or any part thereof in violation of
the Securities Act or any applicable state securities laws, provided, however, that by making the representations herein, such Purchaser does not agree to hold any of the Securities for any minimum period of time and reserves the right,
subject to the provisions of this Agreement and the Registration Rights Agreement, at all times to sell or otherwise dispose of all or any part of such Securities pursuant to an effective registration statement under the Securities Act or under an
exemption from such registration and in compliance with applicable federal and state securities laws. Such Purchaser is acquiring the Securities hereunder in the ordinary course of 

  
 19 








 
its business. Such Purchaser does not presently have any agreement, plan or understanding, directly or indirectly, with any Person to distribute or effect any distribution of any of the
Securities (or any securities which are derivatives thereof) to or through any Person or entity; such Purchaser is not a registered broker-dealer under Section 15 of the Exchange Act. 

(d) Purchaser Status. Such Purchaser is, an “accredited investor” as defined in Rule 501(a) under the Securities
Act. Such Purchaser hereby represents that neither it nor any of its Rule 506(d) Related Parties is a “bad actor” within the meaning of Rule 506(d) promulgated under the Securities Act. For purposes of this Agreement,
“Rule 506(d) Related Party” shall mean a Person or entity covered by the “Bad Actor disqualification” provision of Rule 506(d) of the Securities Act. 

(e) General Solicitation. Such Purchaser is not purchasing the Securities as a result of any advertisement, article, notice or other
communication regarding the Securities published in any newspaper, magazine or similar media or broadcast over television or radio or presented at any seminar or any other general advertisement. 

(f) Experience of Such Purchaser. Such Purchaser, either alone or together with its representatives, has such knowledge,
sophistication and experience in business and financial matters such that it is capable of evaluating the merits and risks of the prospective investment in the Securities. Such Purchaser is able to bear the economic risk of an investment in the
Securities and is able to afford a complete loss of such investment. 
 (g) Access to Information. Such Purchaser acknowledges
that it has had the opportunity to review the SEC Reports and has been afforded (i) the opportunity to ask such questions as it has deemed necessary of, and to receive answers from, representatives of the Company concerning the terms and
conditions of the offering of the Securities and the merits and risks of investing in the Securities; (ii) access to information about the Company and the Subsidiaries and their respective financial condition, results of operations, business,
properties, management and prospects sufficient to enable it to evaluate its investment; and (iii) the opportunity to obtain such additional information that the Company possesses or can acquire without unreasonable effort or expense that is
necessary to make an informed investment decision with respect to the investment. Neither such inquiries nor any other investigation conducted by or on behalf of such Purchaser or its representatives or counsel shall modify, amend or affect such
Purchaser’s right to rely on the truth, accuracy and completeness of the Disclosure Materials and the Company’s representations and warranties contained in the Transaction Documents. 

(h) Independent Investment Decision. Such Purchaser understands that nothing in this Agreement or any other materials presented by or
on behalf of the Company to the Purchaser in connection with the purchase of the Securities constitutes legal, tax, accounting or investment advice. Such Purchaser has consulted such legal, tax, accounting and investment advisors as it, in its sole
discretion, has deemed necessary or appropriate in connection with its purchase of the Securities.

exemptions and the eligibility of such Purchaser to acquire the Securities.
 (j) Regulation M. Such Purchaser is aware that the
anti-manipulation rules of Regulation M under the Exchange Act may apply to sales of Common Shares and other activities with respect to the Common Shares by the Purchasers.

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.
 (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


  
 21 








 
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, including the Initial 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 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. 

  
 22 








 (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. 
 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 

  
 23 








 
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 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
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 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 


  
 24 








 
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. 
 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. 

  
 25 








 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 Securities and shall use its commercially reasonable efforts to take all steps
necessary to cause all of the Securities 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
Securities. 
 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 and Board Observer. 

(a) Director Designation Rights. Subject to Nasdaq Listing Rule 5640 (the “Voting Rights Rule”), for so long as the
Purchasers (and their Affiliates) beneficially own Common Shares, the 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 Purchasers, the “Purchaser
Designee”). For the avoidance of doubt, the 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 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 Purchasers may not assign the
rights set forth in this Section 4.9(a) without the prior written consent of the Company. In the event that Nasdaq informs the Company that it is not in compliance with the Voting Rights Rule as a result of the
Purchaser’s rights under this Section 4.9(a), the 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 Company shall appoint Ronald
W. Eastman 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 

  
 26 








 
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 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: 

(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
Purchaser, 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. 
 (h) Board Observer. The Purchasers
shall be entitled to designate one observer (the “Purchaser Observer”) to the Board of Directors for so long as Purchaser (and its Affiliates) beneficially owns any Common Shares. The Purchaser Observer and the Company shall enter
into a customary board 

  
 27 








 
observer agreement providing for, among other things, the treatment of confidential information, indemnification, and reimbursement of expenses, reasonably acceptable to the Company and the
Purchaser Observer. The Purchaser Observer shall be entitled to attend and participate, and shall be invited to attend and participate, at the Company’s sole expense, in all meetings of the Board of Directors or committees of the Board of
Directors (whether such meetings are in person, by telephone, or otherwise) in a non-voting capacity. The Company shall provide the Purchaser Observer copies of all notices, minutes, consents and other
materials that it provides to the Board of Directors or any committees of the Board of Directors at the same time and in the same manner as such materials are provided to the Board of Directors and such committees. The Purchaser Observer is a non-voting observer and as such, the Company reserves the right to withhold all or part of any information or exclude access to any meeting or portion thereof if the Company reasonably believes that such withholding
or exclusion is reasonably necessary to preserve the attorney-client privilege, to avoid conflicts of interest or for other similar reasons. The Purchasers may not assign the rights set forth in this Section 4.9(h) without
the prior written consent of the Company. The initial Purchaser Observer shall be W. Brooks Andrews. 
 4.10 Company Lock-Up. During the period beginning from the date hereof and continuing to and including the earlier of (a) the date of the closing of the transactions contemplated by the Second Securities Purchase
Agreement (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 “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 Second
Securities Purchase Agreement; (ii) issue 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 Second Registration Statement in connection with this Agreement and the Second 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.

 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 each of the Purchasers, 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. 
 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 each
Purchaser. 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 

  
 32 








 
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. 
 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. 

  
 33 








 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 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 April 30, 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 or Second Securities Purchase Agreement as a result therefrom.

 (c) Upon receipt of a Demand Registration Request, the Company shall as

 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. 
 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
Investors holding an aggregate of at least a majority in interest of the then outstanding Registrable Securities with respect to all of their Registrable Securities included in such Demand Registration, the Company shall cease all efforts to secure
effectiveness of the applicable Demand Registration Statement. 
 Section 3.1.4 Effective Registration. The Company shall use
commercially reasonable efforts to cause the Demand Registration Statement to become effective and remain effective for not less than one hundred eighty (180) days (or such shorter period as will terminate when all Registrable Securities
covered by such Demand Registration Statement have been sold or withdrawn), or, if such Demand Registration Statement relates to an Underwritten Public Offering, such longer period as in the opinion of counsel for the underwriter or underwriters a
Prospectus is required by law to be 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 action to the Investors, delay the filing or initial effectiveness of, or suspend use of, the
Demand Registration Statement (a “Demand Suspension”); provided, however, that the Company shall not be permitted to exercise a Demand Suspension more than once during any twelve (12)-month period for a period not to

Section 3.2.1 Request for Shelf Registration. 

(a) At any time, upon the written request of the Investors (a “Shelf Registration Request”), the Company shall within thirty
(30) days of the date of such request, file with the SEC a shelf Registration Statement pursuant to 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 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 a Shelf Registration Request shall hereinafter be referred to as a “Shelf
Registration.” 
 (b) If on the date of the Shelf Registration Request the Company is not a WKSI, then the Shelf Registration
Request shall specify the aggregate amount of Registrable Securities to be registered, which shall not be less than a majority of the Registrable Securities then 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 thereunder); and (ii) the date as of which the Investors no longer hold Registrable Securities (such period of effectiveness, the “Shelf Period”). Subject
to Section 3.2.4, the Company shall be deemed not to have used its 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 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

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 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 

  
 - 8 - 








 
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 Registration pursuant to the registration rights related to the Second Securities Purchase Agreement on a pro rata basis
that, in the opinion of such managing underwriter or underwriters, can be sold without having such adverse effect and (iii) third, and only if all of the Registrable Securities referred to in clause (ii) have been included in such
Registration, any other securities eligible for inclusion in such Registration. 
 Section 3.3.3 No Effect on Other
Registrations. No Registration of Registrable Securities effected pursuant to a request under this Section 3.3 shall be deemed to have been effected pursuant to Sections 3.1 and 3.2 or shall relieve the Company of its obligations under
Sections 3.1 and 3.2. 
 Section 3.4 Lock-Up Agreements. In connection with each
Registration or sale of Registrable Securities pursuant to Section 3.1, 3.2 or 3.3 conducted as an Underwritten Public Offering, the Company agrees to cause its directors and executive officers, if requested by the underwriters in any such
Underwritten Public Offering, to become bound by and to execute and deliver a customary lock-up agreement with the underwriter(s) of such Underwritten Public

Offering relating to the transfer of any equity securities of the Company held by such Person during the period commencing on the date of the final Prospectus relating to the Underwritten Public
Offering and ending on the date specified by the underwriters (such period not to exceed ninety (90) days plus such additional period as may be requested by the Company or an underwriter to accommodate regulatory restrictions on the publication
or other distribution of research reports and analyst recommendations and opinions, if applicable).

Registrable 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.

expectation of reaching the same income level in the current year;

	 	☐	Any private business development company as defined in section 202(a)(22) of the Investment Advisers Act of 1940; 

  

	 	☐	Any organization described in Section 501(c)(3) of the Internal Revenue Code, corporation, Massachusetts or similar business trust, or partnership, not formed for the specific purpose of acquiring the securities

FORM OF LOCK-UP 







 Lock-Up Agreement 

March __, 2018 
 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
the Purchasers that it does not intend to proceed with the Investment, or (ii) the Purchase Agreement (other than the provisions thereof which survive termination) is terminated prior to payment for and delivery of the Common Stock to be sold
thereunder. 
 The undersigned understands that the Purchasers are entering into the Purchase Agreement and proceeding with the Investment
in reliance upon this Agreement. This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York.
