If any payment or deliverable under this Agreement is subject to any tax, duties, levies, charges, fees or other imposts of any kind (“Taxes”) which INTI is required at law to withhold, then INTI will withhold that amount and deduct
it from the payments required to be made to Mayne Pharma under this Agreement. INTI will promptly provide to Mayne Pharma certificates or any other form of documentary evidence issued by any authority regarding the payment of any such Taxes. INTI
will sign all lawful documents as reasonably requested by Mayne Pharma as is necessary to able Mayne Pharma to take advantage of any applicable legal provision or any double taxation treaties that would result in limiting the amount of any such
Taxes.

amount paid to Mayne Pharma and secure and send to Mayne Pharma the best available evidence of such payment. 
 (c) For any period during the
term of this Agreement where there is no applicable double taxation agreement or treaty, to the extent that Mayne Pharma, acting reasonably, is not able to obtain the benefit of any amounts withheld or deducted by INTI under this Agreement, then
Mayne Pharma shall give notice of this to INTI and INTI must pay Mayne Pharma such additional amounts as necessary to ensure Mayne Pharma receives, when due, a net amount (after deduction or withholding of Taxes in respect of such additional
amounts) equal to the full amount which Mayne Pharma would have received if no deduction or withholding had been made.

 PATENT PROSECUTION, MAINTENANCE, & INFRINGEMENT 

4.1 Prosecution & Maintenance. 

4.1.1 Title to all PATENT RIGHTS pursuant to this Agreement shall reside in JHU. 

  
 Page 6 













 4.1.2 The parties acknowledge that, under the Head License, JHU shall take primary
responsibility for the prosecution and maintenance of all PATENT RIGHTS in the TERRITORY. JHU shall have primary responsibility for the PATENT RIGHTS prosecuted and maintained in any jurisdiction in the TERRITORY, and at INTI’s expense, shall
file, prosecute and maintain all such patents and patent applications that, subject to the terms and conditions of this Agreement, INTI has obtained a license hereunder. JHU shall have full and complete control over all patent prosecution matters in
connection therewith under the PATENT RIGHTS in the TERRITORY, provided however, that Mayne Pharma shall (a) timely provide to INTI copies of non-confidential official actions and written correspondence
with the USPTO regarding the PATENT RIGHTS in the TERRITORY, and (b) consult with INTI and allow INTI an opportunity to comment, which comments Mayne Pharma will consider and as appropriate, pass onto JHU. 

4.1.3 INTI shall be responsible for all reasonable
out-of-pocket expenses associated with the filing, prosecution and maintenance of the ANGIOGENESIS PATENTS RIGHTS and the HEDGEHOG PATENT(s) in the TERRITORY. Provided
Mayne Pharma has provided INTI with at least *** advance written notice of any filing or response deadline or fee due date, by written notification to Mayne Pharma at least *** in advance of any filing or response deadline, or fee due date (or where
Mayne Pharma has not provided sufficient advance notice, such shorter period such that INTI has at least *** to consider its election), INTI may elect not to have a patent application filed or not to pay expenses associated with prosecuting or
maintaining any patent application or patent comprising the PATENT RIGHTS, provided that INTI pays for all costs incurred up to receipt of such notification. Failure to provide such notification can be considered to be INTI’s authorization to
proceed at INTI’s expense. Upon such notification, on behalf of Mayne Pharma, JHU may file, prosecute, and/or maintain such patent applications or patent at its own expense and for its own benefit and any rights or license granted hereunder
held by INTI or any SUBLICENSEE(S) relating to the PATENT RIGHTS which comprise the subject of such patent applications or patent and/or apply to the TERRITORY, shall terminate.  

4.2 Notification. Each party will notify the other promptly in writing when any infringement by another is uncovered or
suspected. 
 4.3 Infringement. 

(a) Mayne Pharma shall have the first right to enforce any patent within PATENT RIGHTS against any infringement or alleged infringement thereof
within LICENSED FIELD in the TERRITORY. Subject to Paragraph 4.5A, *** will pay all reasonable costs and expenses (including reasonable attorney fees for litigation and opinion) incurred by *** in connection with such enforcement (Enforcement
Costs). Before Mayne Pharma commences an action with respect to any infringement of such patents, INTI acknowledges and agrees that Mayne Pharma shall give careful consideration to the views of JHU and to potential effects on the public interest
in making its decision whether or not to sue. INTI acknowledges and agrees that no settlement, consent judgment or other voluntary final disposition of the suit may be entered into without the prior written consent of JHU, which consent shall not be
unreasonably withheld. This right to sue for infringement shall not be used in an arbitrary or capricious manner. INTI shall reasonably cooperate in any such litigation at *** expense, including in accordance with Paragraph


  
 Page 7 













 
4.6. Should INTI seek the first right to enforce any patent within PATENT RIGHTS against any infringement or alleged infringement thereof within LICENSED FIELD in the TERRITORY, then it shall
notify Mayne Pharma who will, if it consents, seek the consent of JHU (which consent INTI acknowledges may be withheld or granted subject to conditions by JHU acting in its discretion). 

(b) If INTI elects not to pay Enforcement Costs in respect of a particular infringement in the TERRITORY, then it shall so notify Mayne Pharma
in writing within *** of receiving notice that an infringement exists, and Mayne Pharma may, in its sole judgment and at its own expense, take steps to enforce any patent and control, settle, and defend such suit in a manner consistent with the
terms and provisions hereof, and recover, for its own account, any damages, awards or settlements resulting therefrom, or may allow JHU to do so. 

4.4 Patent Invalidity Suit. Mayne Pharma shall have the first right to defend any declaratory judgment action or similar proceeding
(including post grant review before any patent office or inter partes review before the Patent Trial and Appeal Board of the USPTO) alleging invalidity of any of the PATENT RIGHTS where such action or similar proceeding is brought by a party
primarily seeking to compete within LICENSED FIELD in the TERRITORY. Subject to Paragraph 4.5A, *** will pay all reasonable costs and expenses (including reasonable attorney fees for litigation and opinion) incurred by *** in connection with such
defense. INTI acknowledges and agrees that no settlement, consent judgment or other voluntary final disposition of the suit may be entered into without the prior written consent of JHU, which consent shall not be unreasonably withheld. Should INTI
seek the first right to defend any declaratory judgment action or similar proceeding (including post grant review before any patent office or inter partes review before the Patent Trial and Appeal Board of the USPTO) alleging invalidity of
any of the PATENT RIGHTS within LICENSED FIELD in the TERRITORY, then it shall notify Mayne Pharma who, if it consents, will seek the consent of JHU (which consent INTI acknowledges may be withheld or granted subject to conditions by Mayne Pharma or
JHU (as applicable) acting in its discretion). If it is not clear whether a party is primarily seeking to compete within LICENSED FIELD or outside the LICENSED FIELD in the TERRITORY, then JHU may elect to take over the sole defense of the action at
its own expense. INTI and Mayne Pharma shall cooperate fully with JHU in connection with any such action at JHU’s expense. 
 4.5
Recovery. Any recovery by Mayne Pharma under Paragraph 4.3 shall be paid: 
 (a) first to *** to reimburse its Enforcement Costs; and

 (b) following *** recovery of its Enforcement Costs, the Parties shall share equally in the recovery. If the Enforcement Costs exceed the
recovery, then *** shall be credited against royalties payable by INTI to Mayne Pharma hereunder in connection with sales of LICENSED PRODUCT covered in the PATENT RIGHTS which are the subject of the infringement suit in the TERRITORY, provided,
however, that any such credit under this Paragraph shall not exceed *** of the royalties otherwise payable to Mayne Pharma with regard to sales in the TERRITORY in any one calendar year, with any excess credit being carried forward to future
calendar years.

enforcement of any patent within PATENT RIGHTS against any infringement or alleged infringement thereof within LICENSED FIELD in the TERRITORY or defense of any declaration judgment or similar proceeding (including post grant review before any
patent office or inter partes review before the Patent Trial and Appeal Board of the USPTO) alleging invalidity of any of the PATENT RIGHTS within LICENSED FIELD in the TERRITORY at its sole discretion, subject to: 

(a) consulting with INTI through a joint litigation committing comprising two appointees of each of Mayne Pharma and INTI, which committee will
discuss the management and course of action with respect to such enforcement or defense, including without limitation, the selection of outside counsel, legal strategy, staff, the engagement of any third party consultants, experts or vendors, the
advancement of any legal theory or basis for infringement or defense, scope of discovery, deadlines or extensions for discovery, filing of motions, taking of depositions, providing admission or stipulations, schedule for hearings, proceedings before
the court, filing of appeals, commencement and conduct of settlement negotiations or any other actions affecting a Party’s rights or obligations or entailing the incurring of cost or expense; and 

(b) Mayne Pharma obtaining the express consent of INTI prior to selecting counsel, bringing any suit in INTI’s name, or entering into any
settlement, consent judgment or other voluntary final disposition of the suit, such consent not be unreasonably withheld, except that if JHU consents to INTI enforcing any patent within the PATENT RIGHTS or defending any declaratory judgment action
or similar proceeding alleging invalidity of any of the PATENT RIGHTS then INTI shall manage the conduct of any such enforcement or defense but will consult with Mayne Pharma on the same terms as would have applied under Paragraph 4.5A(a) and obtain
the prior written consent of Mayne Pharma prior to the events referred to in Paragraph 4.5A(b), such consent not be unreasonably withheld. 

4.6 Conduct of litigation where INTI is a party. Where it is necessary or desirable for INTI to be named as a party in any litigation
referred to in Paragraph 4.3 or 4.4, INTI will do all acts and execute such legal papers as are reasonably requested by Mayne Pharma in connection with such litigation. The counsel selected by Mayne Pharma for the litigation (subject to the express
consent of INTI, not to be unreasonably withheld) shall represent both INTI and Mayne Pharma. Notwithstanding the foregoing, if due to legal conflict, the parties cannot be represented by the same counsel, then each of JHU and Mayne Pharma shall
have the right to retain its own separate legal counsel, in which case, the fees of such separate legal counsel shall still be paid by INTI. 

4.7 Listing on the FDA Orange Book. At the applicable time, INTI must use reasonable commercial efforts to list all patents comprised in
the PATENT RIGHTS promptly in the FDA Orange Book for the LICENSED PRODUCT in the LICENSED FIELD.

ATTORNEYS’ AND EXPERTS’ FEES, AND COURT COSTS (EVEN IF ANY OF JHU OR MAYNE PHARMA HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES, FEES OR COSTS), ARISING OUT OF OR IN CONNECTION WITH THE MANUFACTURE, USE, OR SALE OF THE PRODUCT(S) AND
SERVICE(S) LICENSED UNDER THIS AGREEMENT. INTI AND ANY SUBLICENSEE ASSUME ALL RESPONSIBILITY AND LIABILITY FOR LOSS OR DAMAGE CAUSED BY A PRODUCT AND/OR SERVICE MANUFACTURED, USED, OR SOLD BY INTI OR ANY SUBLICENSEE WHICH IS A LICENSED PRODUCT(S) OR
LICENSED SERVICE(S) AS DEFINED IN THIS AGREEMENT. 
 6.3 Representations and Covenants of Mayne Pharma. 

(a) Mayne Pharma warrants to INTI that (i) it is entitled to grant INTI the sublicence of the PATENT RIGHTS on the terms and conditions
set out in this Agreement; and (ii) Exhibit C (with commercial in confidence information redacted) is a true and complete copy of the Head License; and (iii) it has not, and will not during the term of this Agreement, impose in
favor of any third party any mortgage, pledge, lien, encumbrance, charge or other security interest over the Sublicense or any PATENT RIGHTS, whether that mortgage, pledge, lien, encumbrance, charge or other security interest has a material, adverse
impact on INTI’s rights under this Agreement. 
 (b) Mayne Pharma covenants to INTI that it will use reasonable commercial efforts to
comply with its obligations under the Head License and will not terminate the Head License without cause except with the prior written consent of INTI, such consent not to be unreasonably withheld or delayed. 

ARTICLE 7 

INDEMNIFICATION 
 7.1
Indemnification. INTI shall be responsible for injuries or losses to third parties arising from or related to INTI’s own acts or omissions, or caused by arising from INTI’s use or third party use of LICENSED PRODUCT(S) sold by INTI or
any SUBLICENSEE and LICENSED SERVICE(S) performed by INTI or any SUBLICENSEE, or arising as a consequence of the exercise by INTI or any SUBLICENSEE(S) of any rights granted in this Agreement. JHU and the Inventors will have no legal liability
exposure to third parties if JHU does not license the LICENSED PRODUCT(S) and LICENSED SERVICE(S), and any royalties JHU and the Inventors may receive under the Head License is not adequate compensation for such legal liability exposure. Therefore,
JHU requires INTI to protect JHU and Inventors from such exposure to the same manner and extent to which insurance, if available, would protect JHU and Inventors. Furthermore, JHU and the Inventors will not, under the provisions of the Head License,
this Agreement or otherwise, have control over the manner in which INTI or any SUBLICENSEE(S) or those operating for its account or third parties who purchase LICENSED PRODUCT(S) or LICENSED SERVICE(S) from any of the foregoing entities, develop,
manufacture, market or practice the inventions of LICENSED PRODUCT(S) and LICENSED SERVICE(S). Therefore, 

  
 Page 12 













 
INTI and any SUBLICENSEE shall indemnify, defend with counsel reasonably acceptable to JHU, and hold JHU, The Johns Hopkins Health Systems, their present and former trustees, officers, Inventors
of PATENT RIGHTS (other than HHMI employees), agents, faculty, employees and students harmless as against any judgments, fees, expenses, or other costs arising from or incidental to any product liability or other lawsuit, claim, demand or other
action brought as a consequence of the practice of said inventions by any of the foregoing entities, whether or not JHU or said Inventors, either jointly or severally, is named as a party defendant in any such lawsuit and whether or not JHU or the
Inventors are alleged to be negligent or otherwise responsible for any injuries to persons or property. Practice of the inventions covered by LICENSED PRODUCT(S) and LICENSED SERVICE(S), by an agent or any SUBLICENSEE(S) or a third party on behalf
of or for the account of INTI or by a third party who purchases LICENSED PRODUCT(S) and LICENSED SERVICE(S) from INTI, shall be considered INTI’s practice of said inventions for purposes of this Paragraph. The obligation of INTI to defend and
indemnify as set out in this Paragraph shall survive the termination of this Agreement, shall continue even after assignment of rights and responsibilities to an AFFILIATED COMPANY (but not any other assignment by INTI in accordance with Paragraph
10.8), and shall not be limited by any other limitation of liability elsewhere in this Agreement. 
 7.2 HHMI Indemnification. The
Howard Hughes Medical Institute (“HHMI”), and its trustees, officers, employees, and agents (collectively, “HHMI INDEMNITEES”), will be indemnified, defended by counsel reasonably acceptable to HHMI, and held
harmless by INTI from and against any claim, liability, cost, expense, damage, deficiency, loss, or obligation, of any kind or nature (including, without limitation, reasonable attorneys’ fees and other costs and expenses of defense)
(collectively, “Claims”), based upon, arising out of, or otherwise relating to this Agreement, including without limitation any cause of action relating to product liability. The previous sentence will not apply to any Claim that is
determined with finality by a court of competent jurisdiction to result solely from the gross negligence or willful misconduct of an HHMI INDEMNITEE. Notwithstanding any other provision of this Agreement, INTI’s obligation to defend, indemnify
and hold harmless the HHMI INDEMNITEES under this paragraph will not be subject to any limitation or exclusion of liability or damages or otherwise limited in any way. This provision shall survive the expiration or termination of this Agreement.

 7.2 Indemnification Procedure. A party intending to claim indemnification under this Agreement (“Indemnitee”)
shall promptly notify the indemnifying party (“Indemnitor”) in writing of any lawsuit, claim, demand or other action, or any judgments, fees, expenses or other costs in respect of which the Indemnitee intends to claim such
indemnification. In the case of any HHMI INDEMNITEE, notice shall be given reasonably promptly following actual receipt of written notice thereof by an officer or attorney of HHMI. Notwithstanding the foregoing, the delay or failure of any HHMI
INDEMNITEE to give reasonably prompt notice to an Indemnitor of any such claim shall not affect the rights of such HHMI INDEMNITEE unless, and then only to the extent that, such delay or failure is prejudicial to or otherwise adversely affects the
Indemnitor. The Indemnitee reasonably shall cooperate with the Indemnitor in the defense of the lawsuit, claim, demand or other action, and the Indemnitor shall have the right to control the defense and/or settlement of the lawsuit, claim, demand or
other action; provided, however, that any such settlement shall not require the Indemnitee (a) to admit any liability; (b) to pay any amounts; (c) impose any restriction on any HHMI INDEMNITEE’s conduct of any of its activities;
or (d) not include an unconditional release of all HHMI INDEMNITEES from all liability for claims that are the subject matter of the settled Claim, without the prior written consent of such Indemnitee. The Indemnitee shall use reasonable
efforts to mitigate any fees, expenses or other costs.

 ARTICLE 8 

CONFIDENTIALITY 
 8.1
Confidentiality. If necessary, the parties will exchange information in respect of the subject matter of this Agreement, which they consider to be confidential. The recipient of such information agrees to keep it confidential provided such
information is marked as confidential at the time it is sent to the recipient, or if it is disclosed orally, summarised in writing and identified as ‘confidential’ within *** after its presentation (provided that a failure to do so shall
not detract from the obligations in this Paragraph where it was reasonably apparent that such information was confidential in nature). Without limitation, the recipient agrees to employ all reasonable efforts to maintain the information secret and
confidential, such efforts to be no less than the degree of care employed by the recipient to preserve and safeguard its own confidential information. The information shall not be disclosed or revealed to anyone except employees of the recipient who
have a need to know the information and who have entered into a secrecy agreement with the recipient under which such employees are required to maintain confidential the proprietary information of the recipient and such employees shall be advised by
the recipient of the confidential nature of the information and that the information shall be treated accordingly. 
 The obligations of
this Paragraph 8.1 shall also apply to any SUBLICENSEE(S) provided such information by INTI. Mayne Pharma’s, INTI’s, and SUBLICENSEES’ obligations under this Paragraph 8.1 shall extend until *** after the termination of this
Agreement. 
 The obligations of this Paragraph 8.1 shall apply to confidential information exchanged prior to, on or after the EFFECTIVE
DATE in connection with this Agreement or the transactions contemplated under it. To avoid doubt, the parties agree that nothing in this Agreement detracts from the restrictions on use and disclosure of confidential information under the Second
Amended and Restated Supply and License Agreement, dated May 15, 2015, by and between Mayne Pharma Ventures Pty Ltd., an Affiliated Company of Mayne Pharma, and INTI. 

8.2 Exceptions. The recipient’s obligations under Paragraph 8.1 shall not extend to any part of the information: 

(a) that can be demonstrated to have been in the public domain or publicly known and readily available to the trade or the public prior to the
date of the disclosure; or 
 (b) that can be demonstrated, from written records to have been in the recipient’s possession or readily
available to the recipient from another source not under obligation of secrecy to the disclosing party prior to the disclosure; or 
 (c)
that becomes part of the public domain or publicly known by publication or otherwise, not due to any unauthorized act by the recipient; or 

  
 Page 14 













 (d) that is demonstrated from written records to have been developed by or for the receiving
party without reference to confidential information disclosed by the disclosing party. 
 (e) that is required to be disclosed by law,
government regulation or court order, or any applicable stock exchange. 
 8.3 Right to Publish. JHU may publish manuscripts,
abstracts or the like describing the PATENT RIGHTS and inventions contained therein provided confidential information of INTI as contemplated in Paragraph 8.1, is not included or without first obtaining approval from INTI to include such
confidential information. Otherwise, JHU and the Inventors shall be free to publish manuscripts and abstracts or the like directed to the work done at JHU related to the licensed technology without prior approval. 

ARTICLE 9 

TERM & TERMINATION 

9.1 Term. The term of this Agreement shall commence on the EFFECTIVE DATE and shall continue until the earlier of: (a) the
date of expiration of the last to expire patent included within PATENT RIGHTS in the TERRITORY; or (b) notice by Mayne Pharma with immediate effect promptly after termination or expiry of the Head License in circumstances where Mayne Pharma no
longer has the right to obtain an EXCLUSIVE LICENSE to make, have made, use, import, offer for sale and sell the LICENSED PRODUCT(S) and to provide the LICENSED SERVICE(S) in the TERRITORY under the PATENT RIGHTS in the LICENSED FIELD. 

9.2 Termination By Either Party. This Agreement may be terminated by either party giving written notice to the other party, with
effect immediately (or any later date specified in the notice), in the event that the other party (a) files or has filed against it a petition under the Bankruptcy Act, makes an assignment for the benefit of creditors, has a receiver appointed
for it or a substantial part of its assets, otherwise takes advantage of or has any action taken in respect of it under any statute or law designed for relief of debtors, or (having regard to its legal structure and the jurisdiction in which it is
incorporated or operates) any event analogous to one of the foregoing events happens to it or (b) fails to perform or otherwise breaches any of its obligations hereunder, if either (i) following the giving of notice by the terminating
party of its intent to terminate and stating the grounds therefor, the party receiving such notice shall not have cured the failure or breach within *** or (ii) that failure to perform or breach is not capable of being cured. In no event,
however, shall such notice or intention to terminate be deemed to waive any rights to damages or any other remedy which the party giving notice of breach may have as a consequence of such failure or breach. 

9.3 Termination by Mayne Pharma. Mayne Pharma may terminate this Agreement with immediate effect by notice to INTI if the THIRD SLA
expires or is terminated. 
 9.4 Obligations and Duties upon Termination. If this Agreement is terminated, both parties shall be
released from all obligations and duties imposed or assumed hereunder to the extent so terminated, except as expressly provided to the contrary in this Agreement. Upon termination, both parties shall cease any further use of the confidential
information disclosed to the receiving 

  
 Page 15 













 
party by the other party. Termination of this Agreement, for whatever reason, shall not affect the obligation of either party to make any payments for which it is liable prior to or upon such
termination. Termination shall not affect Mayne Pharma’s right to recover unpaid royalties, fees, reimbursement for patent expenses, or other forms of financial compensation incurred prior to termination. Upon termination INTI shall submit a
final royalty report to Mayne Pharma and any royalty payments, fees, unreimbursed patent expenses and other financial compensation due Mayne Pharma shall become immediately payable. Furthermore, upon termination of this Agreement, as between Mayne
Pharma and INTI, all rights in and to the licensed technology shall revert immediately to Mayne Pharma at no cost to Mayne Pharma. 

ARTICLE 10 

MISCELLANEOUS 
 10.1 Use
of Name. 
 10.1.1 INTI and any SUBLICENSEE shall not use the name of The Johns Hopkins University or The Johns Hopkins Health
System or any of its constituent parts, such as the Johns Hopkins Hospital or any contraction thereof or the name of Inventors in any advertising, promotional, sales literature or fundraising documents without prior written consent from an
authorized representative of JHU. INTI and any SUBLICENSEE(S) shall allow at least fourteen *** notice of any proposed public disclosure for JHU’s review and comment or to provide written consent. 

10.1.2 Mayne Pharma acknowledges that under HHMI policy, Mayne Pharma, AFFILIATED COMPANIES and SUBLICENSEE(S) may not use the name of
HHMI or of any HHMI employee (including Dr. Beachy) in a manner that reasonably could constitute an endorsement of a commercial product or service; but that use for other purposes, even if commercially motivated, is permitted provided that
(1) the use is limited to accurately reporting factual events or occurrences, and (2) any reference to the name of HHMI or any HHMI employees, including Dr. Beachy, in press releases or similar materials intended for public release is
approved by HHMI in advance. 
 10.2 No Partnership. Nothing in this Agreement shall be construed to create any agency,
employment, partnership, joint venture or similar relationship between the parties other than that of a licensor/licensee. Neither party shall have any right or authority whatsoever to incur any liability or obligation (express or implied) or
otherwise act in any manner in the name or on the behalf of the other, or to make any promise, warranty or representation binding on the other. 

10.3 Notice of Claim. Each party shall give the other or its representative immediate notice of any suit or action filed, or prompt
notice of any claim made, against them arising out of the performance of this Agreement or arising out of the practice of the inventions licensed hereunder. 

  
 Page 16 













 10.4 Product Liability. Prior to initial human testing or first commercial sale of
any LICENSED PRODUCT(S) or LICENSED SERVICE(S) in the LICENSED FIELD in the TERRITORY, INTI shall establish and maintain product liability or other appropriate insurance coverage in the minimum amount of *** per claim and will annually present
evidence to JHU or Mayne Pharma that such coverage is being maintained. Upon JHU’s or Mayne Pharma’s request, INTI will furnish it with a Certificate of Insurance of each product liability insurance policy obtained. Each of JHU, HHMI and
Mayne Pharma shall be listed as an additional insured in INTI’s said insurance policies. If such Product Liability insurance is underwritten on a ‘claims made’ basis, INTI agrees that any change in underwriters during the term of this
Agreement will require the purchase of ‘prior acts’ coverage to ensure that coverage will be continuous throughout the term of this Agreement. 

10.5 Governing Law. For consistency with the Head License which is with JHU (a Maryland corporation) and are governed by the laws of the
State of Maryland, this Agreement shall be construed, and legal relations between the parties hereto shall be determined, in accordance with the laws of the State of Maryland applicable to contracts solely executed and wholly to be performed within
the State of Maryland without giving effect to the principles of conflicts of laws. Subject to Paragraph 10.5A, any disputes between the parties to the Agreement shall be brought in the state or federal courts of Maryland. EACH PARTY WAIVES ALL
RIGHTS TO ANY TRIAL BY JURY IN ALL LITIGATION RELATING TO OR ARISING OUT OF THIS AGREEMENT. 
 10.5A Resolution of Disputes. A party
must not start court proceedings (except proceedings seeking interlocutory relief for the protection of intellectual property or confidential information, or proceedings in relation to debt recovery) for a dispute arising out of this Agreement,
including the breach, termination or invalidity of this Agreement, (“Dispute”) unless it has complied with this Paragraph 10.5A. A party claiming that a Dispute has arisen must notify the other party giving details of the
Dispute. When such a notice is given, each party’s respective representatives must first attempt to resolve the Dispute and, if they cannot resolve the Dispute within *** after the notice is given, they must refer the Dispute to each
party’s chief executive officer who must then attempt to resolve it. If the parties cannot resolve the Dispute within six (6) weeks after the notice of the Dispute is given (or longer period if the parties to the Dispute agree in writing),
either party may refer the Dispute to arbitration. If either party exercises that right, the Dispute must be settled by arbitration in accordance with the expedited procedure set out in the Singapore International Arbitration Centre Rules for
Arbitration, as at present in force and as may be amended by the rest of this Paragraph 10.5A. The place of arbitration will be Singapore. There will only be one arbitrator. The arbitration must be conducted in English. The decision of the
arbitrator shall be final and binding and any award rendered thereon may be entered in any court having jurisdiction. The parties hereby waive any and all objections and defenses to such jurisdiction regardless of the nature of such objection or
defense. No dispute affecting the rights or property of HHMI shall be subject to mediation, arbitration or structured negotiations as provided herein. 

10.6 Notice. All notices or communication required or permitted to be given by either party hereunder shall be deemed sufficiently given
if mailed by registered mail or certified mail, return receipt requested, to the other party at its respective address set forth below or to such other address as one party shall give notice of to the other from time to time hereunder.

 10.7 Compliance with All Laws. In all activities undertaken pursuant to this Agreement, both Mayne Pharma

 10.8 Successors and Assigns. Neither this Agreement nor any of the rights or obligations created herein, except for the
right to receive any remuneration hereunder, may be assigned or novated by either party, in whole or in part, without the prior written consent of the other party (which consent must not be unreasonably withheld or delayed), except that either party

other provision of this Agreement, and no waiver shall be effective unless made in writing. Any provision hereof prohibited by or unenforceable under any applicable law of any jurisdiction shall as to such jurisdiction be deemed ineffective and
deleted herefrom without affecting any other provision of this Agreement. It is the desire of the parties hereto that this Agreement be enforced to the maximum extent permitted by law, and should any provision contained herein be held by any
governmental agency or court of competent jurisdiction to be void, illegal and unenforceable, the parties shall negotiate in good faith for a substitute term or provision which carries out the original intent of the parties. 

  
 Page 18 













 10.10 Entire Agreement; Amendment. INTI and Mayne Pharma acknowledge that they have
read this entire Agreement and that this Agreement, including the attached Exhibits constitutes the entire understanding and contract between the parties hereto and supersedes any and all prior or contemporaneous oral or written agreements or
communications with respect to the subject matter hereof, all of which agreements and communications are merged herein. It is expressly understood and agreed that (i) there being no expectations to the contrary between the parties hereto, no
usage of trade, verbal agreement or another regular practice or method dealing within any industry or between the parties hereto shall be used to modify, interpret, supplement or alter in any manner the express terms of this Agreement; and
(ii) this Agreement shall not be modified, amended or in any way altered except by an instrument in writing signed by both of the parties hereto. 

10.11 Delays or Omissions. Except as expressly provided herein, no delay or omission to exercise any right, power or remedy accruing to
any party hereto, shall impair any such right, power or remedy to such party nor shall it be construed to be a waiver of any such breach or default, or an acquiescence therein, or in any similar breach or default be deemed a waiver of any other
breach or default theretofore or thereafter occurring. Any waiver, permit, consent or approval of any kind or character on the part of any party of any breach or default under this Agreement, or any waiver on the part of any party of any provisions
or conditions of this Agreement, must be in writing and shall be effective only to the extent specifically set forth in such writing. All remedies either under this Agreement or by law or otherwise afforded to any party, shall be cumulative and not
alternative. 
 10.12 Force Majeure. If either party fails to fulfill its obligations hereunder (other than an obligation for the
payment of money), when such failure is due to an act of God, or other circumstances beyond its reasonable control, including but not limited to fire, flood, civil commotion, riot, war (declared and undeclared), revolution, or embargoes, then said
failure shall be excused for the duration of such event and for such a time thereafter as is reasonable to enable the parties to resume performance under this Agreement, provided however, that in no event shall such time extend for a period of more
than ***. If a failure to perform continues for more than ***, the other party may terminate this Agreement immediately by giving notice to the affected party. 

10.13 Further Assurances. Each party shall, at any time, and from time to time, prior to or after the EFFECTIVE DATE of this Agreement,
at reasonable request of the other party, execute and deliver to the other such instruments and documents and shall take such actions as may be required to more effectively carry out the terms of this Agreement.

 10.14 Survival. All representations, warranties, covenants and agreements made herein
and which by their express terms or by implication are to be performed after the execution and/or termination hereof, or are prospective in nature, shall survive such execution and/or termination, as the case may be. This shall include Paragraph 3.7
(Payment), 3.10 (Withholding tax) 5.2 (Records), 10.5.1 (Third Party Beneficiaries) and Articles 6, 7, 8, 9 and 10, and Paragraphs 4.3 to 4.6 where Mayne Pharma elects to continue with such litigation after execution and/or termination. 

10.15 No Third Party Beneficiaries. 

10.15.1 HHMI is not a party to this Agreement and has no liability to Mayne Pharma, any of its AFFILIATED COMPANIES or SUBLICENSEEs, or any
user of anything covered by this Agreement, but HHMI is an intended third-party beneficiary of this Agreement and certain of its provisions are for the benefit of HHMI and are enforceable by HHMI in its own name.

which shall be deemed an original and all of which when taken together shall be deemed but one instrument. Any signature, including any electronic symbol or process affirmatively attached to or associated with this AGREEMENT and adopted by JHU or
LICENSEE to sign, authenticate, or accept such contract or record acceptance of the AGREEMENT, hereto shall have the same legal validity and enforceability as a manually executed signature or use of a paper-based recordkeeping system to the fullest
extent permitted by applicable law, including the Federal Electronic Signatures in Global and National Commerce Act or any state law based on the Uniform Electronic Transactions Act, and the parties hereby waive any objection to the contrary.
