Licensed Products are considered “sold”
when billed out or invoiced or, in the event such Licensed Products are not billed out or invoiced, when the consideration for
sale of the Products is received. If a sale, transfer or other disposition with respect to Licensed Products involves consideration
other than cash or is not at arm’s length, then the Net Sales from such sale, transfer or other disposition shall be calculated
from the average selling price for such Licensed Product during the Calendar Quarter in the country where such sale, transfer or
disposition took place. Notwithstanding the foregoing, Net Sales shall not include, and shall be deemed zero with respect to: (i) Licensed
Products used by Checkpoint, its Affiliates or Sublicensees for their internal use (without receipt of value in excess of the cost
of goods), (ii) the distribution of promotional samples of Licensed Products provided free of charge, (iii) Licensed Products provided
free of charge or at a price not to exceed the cost of goods by Checkpoint for Clinical Trials or research, development or evaluation
purposes, or (iv) sales of Licensed Products among Checkpoint and its Sublicensees and their respective Affiliates for resale (provided
such Affiliate or Sublicensee is not the end user).

 

Net Sales of any Licensed Product that is part
of a Combination Product shall be determined on a country-by-country basis as follows: the Net Sales of the Combination Product
(prior to application of the following adjustment) shall be multiplied by the fraction A/(A+B), where A is the net selling price
in such country of a Licensed Product without the additional active ingredient in the Combination Product, if sold separately for
the same dosage as contained in the Combination Product, and B is the net selling price in such country of any other active ingredients
in the combination if sold separately for the same dosage (or form) as contained in the Combination Product. All net selling prices
of the elements of such Combination Product shall be calculated as the average net selling price of the said elements during the
applicable accounting period for which the Net Sales are being calculated. In the event that, in any country, no separate sale
of either such above-designated Licensed Product (containing only such Licensed Product and no other active ingredients) or any
one or more of the active ingredients included in such Combination Product are made during the accounting period in which the sale
was made or if the net selling price for an active ingredient cannot be determined for an accounting period, Net Sales for purposes
of determining payments under this Agreement shall be calculated by multiplying the sales price of the Combination Product by a
mutually agreed percentage based on the relative contribution of the Licensed Product and the other additional active ingredients.

Notwithstanding anything to the contrary, in
the case of discounts on “bundles” of separate products or services which include Licensed Products (such “bundles”
including but not limited to (w) situations where the Licensed Product is sold at a discount to induce the sale of other related
or unrelated products, (x) contingent arrangements involving drugs that share the same NDC (whether the same or different package
sizes), drugs with different NDCs, (y) circumstances in which a discount is conditioned on the achievement of some other performance
requirement for the Licensed Product (e.g. achievement of market share or placement on a formulary tier), or (z) otherwise where
the resulting price concessions or discounts are greater than those which would have been available had the bundled products been
purchased separately or outside the bundled arrangement), Checkpoint may calculate Net Sales and royalties due hereunder by applying
a discount to the price of a Licensed Product equal to the average percentage discount of all products of Checkpoint, its Affiliate(s),
or Sublicensee(s) in a particular “bundle”, calculated as follows:

 

Average percentage

 

	discount on a	=	[1 - (X/Y)] x 100

 

particular “bundle”

 

where X equals the total discounted price of
a particular “bundle” of products, and Y equals the sum of the undiscounted bona fide list prices of each unit of every
product in such “bundle”. If a Licensed Product in a “bundle” is not sold separately, and no bona fide
list price exists for such Licensed Product, Checkpoint and Licensor shall, for purposes of calculating Net Sales and royalties
due hereunder, negotiate in good faith a reasonable imputed list price for such Licensed Product and Net Sales with respect thereto
shall be based on such imputed list price..

 

Undefined terms in the definition of Net Sales
shall be construed in accordance with GAAP but only to the extent consistent with the express terms of the definition of Net Sales.

 

1.56       “Paragraph IV
Certification” means a certification pursuant to the Drug Price Competition and Patent Term Restoration Act of 1984 (Public

or 21 U.S.C. §355(j)(2)(A)(vii)(IV), or any reasonably similar or equivalent certification or notice in the United States
or any jurisdiction outside the United States, included in (or made with respect to or in connection with) a Regulatory Filing
concerning a Licensed Product and challenging the validity, infringement, or enforceability of any Licensor Patent.

 

1.57       “Patent
Prosecution” means, with respect to any Patent Right (a) preparing, filing and prosecuting applications (of all

proceeding or other similar administrative proceeding or administrative appeal thereof and (d) subject to Sections 6.3(d)
and 6.4(f), settling any interference, opposition, revocation, nullification or cancellation proceeding. A Party responsible for

Financial Provisions

 

5.1         License
Fee. Checkpoint shall pay to Licensor a non-refundable, non-creditable license fee of two million U.S. dollars ($2,000,000)
within thirty (30) days of the Effective Date. As of the Effective Date, there are no pending performance obligations on Licensor
to receive the license fee.

 

5.2         Milestone
Payments. Checkpoint shall, with respect to the first Licensed Product to achieve a milestone event below (a “Milestone”),
pay to Licensor the respective non-refundable and non-creditable milestone payment (“Milestone Payment”) under
the column “First Achievement Milestone Payment” within thirty (30) days following Checkpoint’s receipt
of actual knowledge of such achievement. In the event a Milestone (other than the first Milestone listed below) is achieved by
a Second Licensed Product (as defined below), Checkpoint shall pay to Licensor the respective milestone payment under the column
“Second Product Milestone Payment” within thirty (30) days following Checkpoint’s receipt of actual knowledge
of such achievement. For avoidance of doubt, each Milestone Payment in the table below shall only be paid once under this Agreement,
regardless of the number of times such Milestone may be achieved. “Second Licensed Product” means, with respect
to a Milestone, a Licensed Product containing a Compound that was not contained in the Licensed Product that first achieved such
Milestone. For clarity, with respect to each Milestone, a Second Product Milestone cannot be triggered by a Licensed Product containing
the same Compound that achieved the respective First Achievement Milestone, even if for a different indication. By way of further
clarification, with respect to a Licensed Product contained in a Combination Product, the Net Sales that trigger the Milestone
Payment will be that portion of Net Sales attributable to the Licensed Product as provided in the definition of “Net Sales”.
Notwithstanding the table below, upon achievement of a Development Milestone, payments for such Development milestone and all prior
Development Milestones shall be due and payable to the extent not already paid.

Technical Dispute.

 

5.3         Royalty
Payments for Licensed Product.

 

(a)       In
addition to those payments due to Licensor under 5.1 and 5.2 above, Checkpoint shall pay to Licensor a tiered royalty on the Calendar
Year, worldwide aggregate Net Sales of all Licensed Products during the Licensed Product-by-Licensed Product and country-by-country
Royalty Terms by Checkpoint and its Affiliates and Sublicensees (but excluding Net Sales of a given Licensed Product in a given
country after its applicable Royalty Term), at the percentage rates set forth below:

 

	Portion of Aggregate Calendar Year Net Sales of all 
 Licensed Products (U.S. Dollars)	 	 	Incremental Royalty Rate	 
	$* to $*	 	 	*	%
	More than $* to $*	 	 	*	%
	More than $*	 	 	*	%

 

The thresholds in the above table shall be
pro-rated for any Calendar Year in which the first Royalty Term commences or the last Royalty Term expires or terminates by multiplying
such threshold (e.g., $500 million, $1 billion) by the number of days such Royalty Term was in effect during such Calendar
Year and dividing the result by 365.

 

(b)       On
a Licensed Product-by-Licensed Product and country-by-country basis upon expiration of the Royalty Term, for a Licensed Product
in a country, the rights, licenses and sublicenses granted to Checkpoint hereunder with respect to such Licensed Product in such
country shall continue in effect but become exclusive fully paid-up, royalty-free, transferable (to the extent not transferable
previously), perpetual and irrevocable, provided that Checkpoint shall remain liable for any unpaid Milestone Payments and any
royalty payments previously owed or accrued. For the avoidance of doubt, in a country where no Licensor Patent containing a Valid
Claim covering a Licensed Product has ever existed nor ever exists, no royalties shall be due.

shall accrue at the time provided therefor by GAAP. Payments in the nature of royalty obligations that have accrued during a particular
Calendar Quarter shall be paid, on a Calendar Quarter basis, within 60 days after the end of each Calendar Quarter commencing
with the Calendar Quarter in which the First Commercial Sale occurred.

 

5.5         Royalty
Reports and Records Retention. Within sixty (60) days after the end of each Calendar Quarter during which Licensed Products
have been sold, Checkpoint shall deliver to Licensor, together with the applicable royalty/payment in the nature of royalties payment
due, a written report, on a Licensed Product-by-Licensed Product and country-by-country basis, of Net Sales for such Calendar Quarter.
Such report shall (i) total Net Sales for each Licensed Product and Combination Product (including an itemization of the deductions
applied to such gross sales to derive such Net Sales and if a Licensed Product is part of a Combination Product the percentage
of the Combination Product’s Net Sales attributed to the Licensed Product) during the relevant Calendar Quarter, in each
case on a dosage-by-dosage, country-by-country basis, including a summary of currency exchange rates used in the calculations,
and (ii) the calculation of royalties due on the foregoing. In addition for any Sublicense, the report shall provide the information
in clauses (i) through (ii) above. Such report shall be deemed “Confidential Information” of Checkpoint subject
to the obligations of Article VII of this Agreement. For three years after each sale of a Licensed Product, Checkpoint shall
keep (and shall cause its Affiliates and Sublicensees to keep) complete and accurate records of such sale in sufficient detail
to confirm the accuracy of the royalty or royalty/payment in the nature of royalties calculations hereunder.

 

5.6         Audits.

 

(a)       Upon
the written request of Licensor, and not more than once in each Calendar Year, Checkpoint shall permit an independent certified
public accounting firm (“Auditors”) of nationally recognized standing selected by Licensor and reasonably acceptable
to Checkpoint, at Licensor’s expense, to have access to and to review, during normal business hours upon reasonable prior
written notice, the applicable records of Checkpoint and its Affiliates or Sublicensees to verify the accuracy of the royalty reports
and the Milestone Payments for Milestones which are not Development Milestones. Such review may cover: (i) the records for
sales made in any Calendar Year ending not more than three years before the date of such request, and (ii) only those periods that
have not been subject to a prior audit. The accounting firm shall disclose to Licensor only whether the royalty reports and Milestone
Payments are correct or incorrect and the specific details concerning any discrepancies. No other information shall be provided
to Licensor by the Auditors. This right to audit shall remain in effect during the Term of this Agreement and for a period of two
(2) years after the termination of this Agreement.

 

    	 	19	 

     

    

 

(b)       If
such accounting firm concludes that additional royalties or Milestone Payments were owed during such period, Checkpoint shall pay
the additional royalties and Milestone Payments within 30 days after the date such public accounting firm delivers to Checkpoint
such accounting firm’s written report. If such accounting firm concludes that an overpayment was made, such overpayment shall
be fully creditable against amounts payable in subsequent payment periods or at Checkpoint’s request, shall be reimbursed
to Checkpoint within 30 days after the date such public accounting firm delivers such report to Checkpoint. Licensor shall
pay for the cost of any audit by Licensor, unless Checkpoint has underpaid Licensor by $50,000 or more for a specific royalty period,
in which case Checkpoint shall pay for the reasonable costs of audit.

 

(c)       Each
Party shall treat all information that it receives under this Section 5.6 in accordance with the confidentiality provisions
of Article VII of this Agreement, and shall cause its accounting firm to enter into an acceptable confidentiality agreement
with the audited Party obligating such firm to retain all such financial information in confidence pursuant to such confidentiality
agreement, except to the extent necessary for a Party to enforce its rights under the Agreement.

 

5.7         Mode
of Payment and Currency. All payments to Licensor under this Agreement, whether or not in respect of Net Sales or milestone
events, shall be made by deposit of U.S. Dollars in the requisite amount to such bank account as Licensor may from time to time
designate by advance written notice to Checkpoint. Conversion of sales or expenses recorded in local currencies to Dollars will
be performed in a manner consistent with Checkpoint’s normal practices used to prepare its audited financial statements for
external reporting purposes, provided that such practices use a widely accepted source of published exchange rates. These practices
are set forth on Schedule 5 attached hereto. Based on the resulting Net Sales in U.S. Dollars, the then applicable royalties/payment
in the nature of royalties shall be calculated.

 

5.8         Late
Payments. If a Party does not receive payment of any sum due to it on or before the due date therefor, simple interest shall
thereafter accrue on the sum due to such Party from the due date until the date of payment at a rate equal to the lesser of (a) U.S.
Dollar one-month LIBOR as of the date such payment was due (taken from a widely accepted source of published interest rates), plus
three (3) percentage points, or (b) the maximum rate permissible under applicable Law. Accrual and payment of interest
shall not be deemed to excuse or cure breaches of contract arising from late payment or nonpayment.

 

    	 	20	 

     

    

 

5.9         Taxes.
All amounts due hereunder exclude all applicable sales, use, and other taxes and duties, and Checkpoint shall be responsible
for payment of all such taxes (other than based on Licensor’s income) and duties and any related penalties and interest,
arising from the payment of amounts due under this Agreement. The Parties agree to cooperate with one another and use Commercially
Reasonable Efforts to avoid or reduce tax withholding or similar obligations in respect of payments in the nature of royalties,
Milestone Payments, and other payments made by Checkpoint to Licensor under this Agreement. To the extent Checkpoint is required
to withhold taxes on any payment to Licensor, Checkpoint shall pay the amounts of such taxes to the proper governmental authority
in a timely manner and promptly transmit to Licensor official receipts issued by the appropriate taxing authority and/or an official
tax certificate, or such other evidence as Licensor may reasonably request, to establish that such taxes have been paid. Licensor
shall provide Checkpoint any tax forms that may be reasonably necessary in order for Checkpoint to not withhold tax or to withhold
tax at a reduced rate under an applicable bilateral income tax treaty. Licensor shall use Commercially Reasonable Efforts to provide
any such tax forms to Checkpoint at least 45 days before the due date for any payment for which Licensor desires that Checkpoint
apply a reduced withholding rate. Each Party shall provide the others with reasonable assistance to enable the recovery, as permitted
by applicable law, of withholding taxes, value added taxes, or similar obligations resulting from payments made under this Agreement,
such recovery to be for the benefit of the Party bearing such withholding tax or value added tax. Notwithstanding the foregoing,
if Checkpoint transfers or sublicenses any rights under this Agreement, Drug Approval Applications or Regulatory Approvals, Development
Inventions or relocates or assigns this Agreement and as a result Checkpoint or its assignee is required to withhold or deduct
any taxes by any government outside the United States, any subdivision thereof, or any other governmental unit within the territory
of such government (such taxes collectively referred to as “Charges”), in excess of Charges that Licensor would
otherwise be required to pay had such transfer, relocation, or assignment not been made, or Licensor is required to pay any Charge
imposed by any government outside the United States in excess of Charges that Licensor would otherwise be required to pay had such
transfer or assignment not been made, Checkpoint shall pay such additional amounts so that payments received by Licensor net of
all Charges, shall equal the amount to which Licensor would have been entitled had there been no such Charges, provided, however
that Checkpoint shall have no obligation to pay any additional amount to the extent that the Charges are imposed by reason of Licensor
failing to provide a form or similar other evidence reasonably requested by Checkpoint that would allow for a reduction or exemption
of such Charges that Licensor is legally able to provide (including, for the avoidance of doubt, Licensor’s qualification
for the benefit of an applicable income tax convention).

Inventions and Patents

 

6.1         Patent
Prosecution and Maintenance.

 

(a) Patents. Checkpoint
shall reimburse up to $50,000 in expenses (including attorney’s fees) incurred by Licensor for filing of patent applications
(national, international or PCT) included in the Licensor Patents and filed prior to the Effective Date within thirty (30) days
of receipt of Licensor’s invoice for such expenses. Thereafter Checkpoint shall be solely responsible for Patent Prosecution
of the Licensor Patents worldwide. Except as provided in Section 6.1(b), Checkpoint shall assume and have sole responsibility
for Patent Prosecution for the Licensor Patents in the Territory. Checkpoint will, to the extent reasonably practicable, provide
Licensor a reasonable opportunity to review and comment on any material patent filings or correspondence with patent authorities
pertaining to the Licensor Patents, provided that all decisions with respect to Patent Prosecution of the Licensor Patents under
this Section 6.1(a) shall be made by Checkpoint in its sole reasonable discretion. In the event any Licensor Patents come
under the Control of Licensor after the Effective Date Licensor shall promptly notify Checkpoint. Checkpoint shall not abandon
prosecution or maintenance of any Licensor Patent without first notifying Licensor in a reasonably timely manner of Checkpoint’s
intention and reason therefor, and providing Licensor with reasonable opportunity to consider to assume, with no obligation to
do so, responsibility for prosecution and maintenance of such Licensor Patent as set forth in Section 6.1(b).

 

    	 	21	 

     

    

 

(b)       Abandonment.
If Checkpoint provides Licensor with written notification that it will no longer support or pursue the filing, prosecution,
or maintenance (“Abandonment” and when uses as a verb “Abandon”) of a specified Licensor
Patent in a particular country (an “Abandoned Patent”), then (a) Checkpoint’s responsibility for
such filing, prosecution, or maintenance of the Abandoned Patent in such country, and the fees and costs related thereto, will
terminate on the earlier of (x) the date sixty (60) Calendar Days after Licensor’s receipt of such written notice
from Checkpoint or (y) Licensor’s assumption of the filing, prosecution and maintenance of such Abandoned Patent in
such country, and (b) the specified Abandoned Patent shall no longer be deemed a Licensor Patent hereunder. If Checkpoint
Abandons all Licensor Patents in a country, Licensor by notice to Checkpoint may terminate such country from this Agreement and
such country will become an “Abandoned Terminated Country”. Following Licensor’s notice, Checkpoint’s
(and its Sublicensees’) rights to any Licensor Patents in such country shall terminate.

 

6.2         Certification
under Drug Price Competition and Patent Restoration Act. Each of Licensor and Checkpoint shall immediately give written notice
to the other of any Paragraph IV Certification.

 

6.3         Enforcement
of Patents.

 

(a)       Notice.
If either Party becomes aware of (i) any actual, potential, or alleged infringement of any of the rights to Licensor Patents
granted to Checkpoint under this Agreement with respect to Licensed Products, (ii) misappropriation of any Licensor Know-How or
(iii) a Paragraph IV Certification a certification (each of subclauses (i), (ii) and (iii), an “Infringement”)
and, such Party shall give to the other Party prompt and reasonably detailed written notice of such actual, potential, or alleged
Infringement. Notwithstanding the foregoing, each Party shall notify the other Party within two (2) Business Days of its receipt
of, or receipt of notice of, any Paragraph IV Certification. This Section 6.3 sets forth the rights of the Parties to
commence and prosecute an action relating to such Third Party Infringement (an “Offensive Enforcement Action”).

 

(b)       Right
to Bring an Action for Licensor’s Patents. Checkpoint shall have (i) the right, but not the obligation to undertake
control of, and manage and prosecute, compromise or settle, including selection of counsel (collectively, “Prosecute”),
any Offensive Enforcement Action relating to a Paragraph IV Certification and (ii) the right but not the obligation to Prosecute
any other Offensive Infringement Action. If Checkpoint has not exercised its first right to Prosecute a non Paragraph IV Offensive
Infringement Action within one hundred eighty (180) days of receipt of notice of the same, or a Paragraph IV Offensive Infringement
Action within twenty (20) days of receipt of notice of same, it shall within five (5) days notify Licensor in writing
and Licensor may, by written notice to Checkpoint, Prosecute such action (either such Party who Prosecutes such action, the “Prosecuting
Party”). The non-Prosecuting Party may, in its sole discretion and at its expense, join in any Offensive Infringement
Action and in such case shall reasonably cooperate with the Prosecuting Party. At the Prosecuting Party’s request the non-Prosecuting
Party shall provide the Prosecuting Party with all relevant documentation (as may be requested by the Prosecuting Party) evidencing
that the Prosecuting Party is validly empowered by the non-Prosecuting Party to initiate an Offensive Infringement Action. The
non-Prosecuting Party shall be under the obligation to join the Prosecuting Party in its Offensive Infringement Action if the Prosecuting
Party determines that this is necessary to demonstrate “standing to sue”, provided that the Prosecuting Party shall
pay the fees (including attorneys’ fees) if the non-Prosecuting Party retains its own counsel. The Prosecuting Party shall
have the sole and exclusive right to select counsel for any suit initiated by it pursuant to this Section 6.3 (but not the
non-Prosecuting Party’s counsel). Checkpoint’s or Licensor’s rights under this Section may be exercised by their
respective Affiliates or in Checkpoint’s case, Sublicensees.

 

    	 	22	 

     

    

 

(c)       Costs
and expenses of an Action. Subject to Section 6.3(b) and (f), each Party involved in an Action under Section 6.3(b)
shall pay its own costs and expenses incurred in connection with such Action.

 

(d)       Settlement.
No Party shall settle or otherwise compromise (or resolve by consent to the entry of judgment upon) any Offensive Infringement
Action or Patent Prosecution by admitting that any Licensor Patent is to any extent invalid or unenforceable or any settlement
(or consent to the entry of a judgment) that entails any payment by the other Party, any license, covenant not to sue relating
to, dedication to the public of, abandonment of, any Licensor Technology or would otherwise grant any rights to Manufacture, use,
sell or otherwise commercialize a Competing Product, or materially adversely affect the rights of the other Party, without the
other Party’s prior written consent.

 

(e)       Reasonable
Assistance. Each Party (if it is not the Party Prosecuting or defending Licensor’s Patent Rights) shall provide reasonable
assistance to the other Party, including providing access to relevant documents and other evidence and making its employees and
consultants available, subject to the other Party’s reimbursement of any reasonable out-of-pocket expenses incurred on an
on-going basis by the non-enforcing or non-defending Party in providing such assistance.

 

(f)       Distribution
of Amounts Recovered. Any amounts recovered by the Party initiating an Offensive Infringement Action pursuant to this Section 6.3,
whether by settlement or judgment, shall be allocated in the following order: (i) to reimburse the Prosecuting Party for any
costs incurred; (ii) to reimburse the non-Prosecuting Party for its costs incurred in such Offensive Infringement Action, if it
joins (as opposed to taking over) such Offensive Infringement Action; and (iii) the remaining amount of such recovery shall (A) if
Checkpoint (or a Sublicensee) is the Prosecuting Party in the Offensive Infringement Action, the remainder shall be allocated to
Checkpoint and the portion thereof attributable to “lost sales” shall be deemed to be Net Sales for the Calendar Quarter
in which the amount is actually received by Checkpoint and Checkpoint shall pay to Licensor a royalty on such portion based on
the royalty rates set forth in Section 5.3(a), and the portion thereof not attributable to “lost sales” shall
be allocated to Checkpoint and (B) if Licensor is the Prosecuting Party then the remaining amount of the recovery shall be
retained by the Licensor.

 

(g)       Irrespective
of whether Checkpoint or the Licensor decide to take any action under Section 6.3(b), the payment obligations under Section 5
shall remain unaffected.

 

    	 	23	 

     

    

 

6.4         Third
Party Actions Claiming Infringement.

 

(a)       Notice.
If either Licensor or Checkpoint becomes aware of any Third Party Action, such Party shall promptly notify the other of all
details regarding such claim or action that is reasonably available to such Party.

 

(b)       Duty
to Defend. Subject to the respective indemnity obligations of the Parties set forth in Article IX, Checkpoint shall have
the obligation, at its sole cost and expense, to defend a Third Party Action described in Section 6.4(a) and (subject to Section 6.4(f))
to compromise or settle such Third Party Action. Checkpoint shall have the sole and exclusive right to select counsel for such
Third Party Action.

 

(c)       Consultation.
Checkpoint shall be the “Controlling Party” in a Third Party Action. The Controlling Party shall consult
with the non-Controlling Party, pursuant to an appropriate joint defense or common interest agreement, on all material aspects
of the defense. The non-Controlling Party shall have a reasonable opportunity for meaningful participation in decision-making and
formulation of defense strategy. The Parties shall reasonably cooperate with each other in all such actions or proceedings. The
non-Controlling Party will be entitled to join the Third Party Action and be represented by independent counsel of its own choice
at its own expense.

 

(d)       Appeal.
Subject to the respective indemnity obligations of the Parties set forth in Article IX, in the event that a judgment in
a Third Party Action is entered against Licensor and an appeal is available, the Controlling Party shall, in the absence of the
non-Controlling Party’s written consent to the contrary, have the obligation to file such appeal. If applicable Law requires
the non-Controlling Party’s involvement in an appeal, the non-Controlling Party shall be a nominal party in the appeal and
shall provide reasonable cooperation to such Party at such Party’s expense.

 

(e)       Costs
and expenses of an Action. Subject to the respective indemnity obligations of the Parties set forth in Article IX, the
Controlling Party shall pay all costs and expenses associated with such Third Party Action other than the expenses of the other
Party if the other Party elects to join such Third Party Action, (as provided in the last sentence of Section 6.4(c)). For
the avoidance of doubt, all damage and liability awards and settlement payments shall be paid by the Controlling Party subject
to the respective indemnity obligations of the Parties set forth in Article IX.

 

(f)       No
Settlement without Consent. Neither Licensor or Checkpoint shall settle or otherwise compromise (or resolve by consent to the
entry of judgment upon) any Third Party Action or Patent Prosecution by admitting that any Licensor Patent is to any extent invalid
or unenforceable or that any Licensed Product, or its use, Development, importation, manufacture or sale infringes such Third Party’s
intellectual property rights, or entering into a settlement providing for a license, covenant not to sue relating to, dedication
to the public of, abandonment of, any Licensor Technology or would otherwise grant any rights to Manufacture, use, sell or otherwise
commercialize a Competing Product or materially adversely affects the rights of the other Party, in each case without the other
Party’s prior written consent.

 

    	 	24	 

     

    

 

(g)       The
payment obligations under Section 5 shall remain unaffected during or following any Third Party Action.

 

6.5         Trademark
Infringement.

 

(a)       With
respect to any and all claims instituted by Third Parties against Licensor or Checkpoint or any of their respective Affiliates
or Sublicensees for Trademark infringement involving the Marketing of the Licensed Products, Checkpoint shall be solely responsible
for, and indemnify Licensor against, any and all Losses arising out of or resulting from the use of any Trademarks.

 

(b)       In
the event that a Party becomes aware of actual or threatened infringement of a Trademark used in connection with a Licensed Product,
that Party shall promptly notify the other Party in writing. Checkpoint shall have the right but not the obligation to bring an
action with respect to such infringement against any Third Party for infringement of a Trademark used in connection with a Licensed
Product. Checkpoint shall bear all out-of-pocket costs and expenses of the action (including court costs, reasonable fees of attorneys,
accountants and other experts and other expenses of litigation or proceedings) and shall be entitled to any recovery in such infringement
action.

to the extent reasonably practicable, (i) first have given written notice to the other Party and given such other Party a
reasonable opportunity to take appropriate action and (ii) cooperate with such other Party as necessary to obtain an appropriate
protective order or other protective remedy or treatment; provided, further, that in each case, the Confidential Information disclosed

Third Party), and provided that (i) each individual and entity to whom such Confidential Information is disclosed is bound
in writing to non-use and non-disclosure obligations (or in the case of attorneys or accountants, an equivalent professional duty

INDEMNIFICATION; LIMITATION OF LIABILITY; INSURANCE

 

9.1         Indemnification
by Checkpoint. Checkpoint shall indemnify, defend and hold Licensor and its Affiliates, and each of their respective employees,
officers, directors and agents (the “Licensor Indemnitees”) harmless from and against any and all liabilities,
damages, penalties, fines, losses, costs and expenses (including reasonable attorneys’ fees and expenses) (individually and
collectively, “Losses”) to the extent arising out of any and all Third Party claims, demands, actions or other
proceedings (each, a “Claim”) arising out of (a) the testing, use, Development or Commercialization of
a Compound or any Licensed Product by or on behalf of Checkpoint, any of the Checkpoint Indemnitees or any Sublicensee, (b) Checkpoint’s,
its Affiliates’ or its Sublicensees’ material breach of this Agreement, (c) misappropriation or infringement of,
or the use of, any Product Trademarks, (d) Checkpoint’s or its Affiliates’ breach or noncompliance with the terms of
any Sublicense arising prior to or as a result of the termination of this Agreement, or (e) Checkpoint’s, its Affiliates’
or its Sublicensees’ gross negligence or willful misconduct, excluding, in the case of each of (a)-(d) above, any Claim or
Loss with respect to which Licensor has an obligation to indemnify Checkpoint Indemnitees pursuant to Section 9.2.

 

9.2         Indemnification
by Licensor. Licensor shall indemnify, defend and hold Checkpoint and its Affiliates and each of their respective agents, employees,
officers and directors (the “Checkpoint Indemnitees”) harmless from and against any and Losses to the extent
arising out of any and all Claims arising out of (a) Licensor’s failure to properly conduct the Work Plan, (b) Licensor’s
material breach of this Agreement, (c) the use, Development or Commercialization of a Compound or any Licensed Product by or on
behalf of Licensor or any of the Licensor Indemnitees or any licensee thereof (specifically excluding product liability claims
arising out of Licensed Product sold or distributed by Checkpoint, its Affiliates or Sublicensee), or (d) Licensor’s
gross negligence, willful misconduct, excluding, in the case of each of (a)-(d) above, any Claim or Loss with respect to which
Checkpoint has an obligation to indemnify Licensor Indemnitees pursuant to Section 9.1.

 

9.3         Procedure.

 

(a)       The
Party or other Person intending to claim indemnification under this Article IX (an “Indemnified Party”) shall
promptly notify the opposed Party (the “Indemnifying Party”) of any Claim in respect of which the Indemnified Party
intends to claim such indemnification (provided, that no delay or deficiency on the part of the Indemnified Party in so notifying
the Indemnifying Party will relieve the Indemnifying Party of any liability or obligation under this Agreement except to the extent
the Indemnifying Party has suffered actual prejudice directly caused by the delay or other deficiency), and the Indemnifying Party
shall assume the defense thereof (with counsel selected by the Indemnifying Party and reasonably satisfactory to the Indemnified
Party) whether or not such Claim is rightfully brought; provided, however, that an Indemnified Party shall have the right to retain
its own counsel and to participate in the defense thereof, with the fees and expenses to be paid by the Indemnified Party unless
the Indemnifying Party does not assume the defense or unless a representation of both the Indemnified Party and the Indemnifying
Party by the same counsel would be inappropriate due to the actual or potential differing interests between them, in which case
the reasonable fees and expenses of counsel retained by the Indemnified Party shall be paid by the Indemnifying Party. (Provided,
that in no event shall the Indemnifying Party be required to pay for more than one separate counsel no matter the number or circumstances
of all Indemnified Parties.)

 

(b)       If
the Indemnifying Party shall fail to timely assume the defense of and reasonably defend such Claim, the Indemnified Party shall
have the right to retain or assume control of such defense and the Indemnifying Party shall pay (as incurred and on demand) the
fees and expenses of counsel retained by the Indemnified Party.

 

    	 	31	 

     

    

 

(c)       The
Indemnifying Party shall not be liable for the indemnification of any Claim settled (or resolved by consent to the entry of judgment)
without the written consent of the Indemnifying Party. Also, if the Indemnifying Party shall control the defense of any such Claim,
the Indemnifying Party shall have the right to settle such Claim; provided, that the Indemnifying Party shall obtain the prior
written consent (which shall not be unreasonably withheld or delayed) of the Indemnified Party before entering into any settlement
of (or resolving by consent to the entry of judgment upon) such Claim unless (i) there is no finding or admission of any violation
of law or any violation of the rights of any person by an Indemnified Party, no requirement that the Indemnified Party admit negligence,
fault or culpability, and no adverse effect on any other claims that may be made by or against the Indemnified Party and (ii) the
sole relief provided is monetary damages that are paid in full by the Indemnifying Party and such settlement does not require the
Indemnified Party to take (or refrain from taking) any action.

 

(d)       The
Indemnified Party, and its employees and agents, shall cooperate fully with the Indemnifying Party and its legal representatives
in the investigations of any Claim.

 

(e)       Regardless
of who controls the defense, each Party hereto shall reasonably cooperate in the defense as may be requested.

 

9.4         Expenses.
As the Parties intend complete indemnification, all costs and expenses of enforcing any provision of this Article IX shall
also be reimbursed by the Indemnifying Party.

 

9.5         Limitation
of Liability. IN NO EVENT SHALL EITHER PARTY OR ITS AFFILIATES BE LIABLE TO THE OTHER PARTY FOR ANY SPECIAL, INCIDENTAL, PUNITIVE,
EXEMPLARY OR CONSEQUENTIAL DAMAGES OR LOST PROFITS ARISING OUT OF A BREACH OF THIS AGREEMENT, PROVIDED THAT, NOTWITHSTANDING ANYTHING
TO THE CONTRARY, THE FOREGOING SHALL NOT BE CONSTRUED TO LIMIT THE INDEMNITY OBLIGATIONS SET FORTH IN SECTIONS 9.1 AND 9.2, OR
EITHER PARTY’S LIABILITY FOR A BREACH OF ARTICLE VII.

 

9.6         Insurance.
During the term of this Agreement and for a period of five (5) years after its expiration or earlier termination (measured
by termination or expiration of the last Licensed Product for a country whose Royalty Term is in effect), Checkpoint shall obtain
insurance as follows. The insurance shall insure Checkpoint against all liability related to its activities relating to the Development,
Manufacture or sale of Licensed Products subject to this Agreement, subject to the limits set forth above. The insurance above,
shall be in amounts that are reasonable and customary in the pharmaceutical industry for the Territory, but in no event shall any
Checkpoint’s liability insurance relating to commercial Manufacture, sale or distribution of a Licensed Product provide coverage
less than two million U.S. dollars (U.S. $2,000,000) per occurrence (or claim) and an annual aggregate of two million U.S. dollars
(U.S. $2,000,000). Policies for the Development, commercial Manufacture, sale or distribution of a Licensed Product shall include
a contractual endorsement naming Licensor as an additional insured in relation to liabilities arising from its obligations under
the terms of this Agreement and require the insurance carriers to provide Licensor with no less than thirty (30) days’ written
notice of any change in the terms or coverage of the policies or their cancellation.

TERM AND TERMINATION

 

10.1       Term
and Expiration. The term of this Agreement shall commence on the Effective Date and, unless earlier terminated as provided
in this Article X, shall continue in full force and effect, on a country-by-country and Licensed Product-by-Licensed Product
basis until the Royalty Term in such country with respect to such Licensed Product expires, at which time this Agreement shall
expire in its entirety with respect to such Licensed Product in such country (the “Term”).

 

10.2       Termination
upon Material Breach. If a Party breaches any of its material obligations under this Agreement (a “Material Breach”),
the other Party may give to the breaching Party a written notice specifying the nature of the Material Breach, requiring it to
cure such Material Breach, and, if desired, stating its intention to terminate this Agreement if such Material Breach is not cured.
If such Material Breach is not capable of being cured, or is capable of being cured but nonetheless has not within 60 days
after the receipt of such notice been cured, then the non-breaching Party (in addition to and not in lieu of all other available
rights and remedies) be entitled to at its option either (a) terminate this Agreement immediately by written notice to the
other Party, or (b) continue this Agreement in full force and effect and seek any legal or equitable remedies that the non-breaching
Party may have.

 

10.3       Termination
for Insolvency. Either Party (i.e., the non-insolvent Party) may terminate this Agreement, if, at any time, a petition in bankruptcy
or insolvency or for reorganization or for an arrangement or for the appointment of a receiver or trustee of the Party or of substantially
all of its assets, or if the other Party proposes a written agreement of composition or extension of substantially all of its debts,
or if the other Party shall be served with an involuntary petition against it, filed in any insolvency proceeding, and such petition
shall not be dismissed within sixty (60) days after the filing thereof, or if the other Party shall propose or be a party
to any dissolution or liquidation, or if the other Party shall make an assignment of substantially all of its assets for the benefit
of creditors.

 

10.4       Termination
for Patent Challenge. Licensor will be permitted to terminate this Agreement by written notice effective upon receipt if Checkpoint
or its Affiliates or its Sublicensees, directly or indirectly through assistance granted to a Third Party, commence any interference
or opposition proceeding, challenge in a legal or administrative proceeding the validity or enforceability of, or oppose in a legal
or administrative proceeding any extension of or the grant of a supplementary protection certificate with respect to, any Licensor
Patents (a “Patent Challenge”). Checkpoint will include provisions in all agreements granting Sublicenses of Checkpoint’s
rights hereunder (other than agreements with manufacturers, services providers, distributors and other agents) providing that if
the Sublicensee or its Affiliates undertake a Patent Challenge with respect to any Licensor Patents under which the Sublicensee
is Sublicensed, Checkpoint will be permitted to terminate such Sublicense agreement. If a Sublicensee of Checkpoint (or an Affiliate
of such Sublicensee) undertakes a Patent Challenge of any such Licensor Patent Rights under which such Sublicensee is sublicensed,
then Checkpoint upon receipt of notice from Licensor of such Patent Challenge will terminate the applicable Sublicense agreement.
If Checkpoint fails to so terminate such Sublicense agreement, Licensor may terminate Checkpoint’s right to Sublicense in
the country(ies) covered by such Sublicense agreement and any Sublicenses previously granted in such country(ies) shall automatically
terminate. In connection with such Sublicense termination, Checkpoint shall cooperate with Licensor’s reasonable requests
to cause such a terminated Sublicensee to discontinue activities with respect to the Licensed Product in such country(ies).

 

    	 	33	 

     

    

 

10.5       Termination
for Convenience. This Agreement may be terminated by Checkpoint at any time for its convenience upon sixty (60) days prior
written notice to Licensor.

 

10.6       Termination
for Suspension of Development. If prior to Regulatory Approval of a Licensed Product, Checkpoint or its Affiliates provides
Notice of Termination or Suspension, then Licensor may terminate this Agreement on thirty (30) days’ notice to Checkpoint.

 

10.7       Termination
for Good Scientific Reason. Checkpoint may terminate this Agreement with respect to any specific Compound and the related Licensed
Product upon sixty (60) days’ prior written notice to Licensor if (i) such Compound or Licensed Product has an
adverse safety profile or causes serious adverse reactions; or (ii) Checkpoint reasonably determines that such Licensed Product
will not qualify for Regulatory Approval in the United States.

 

10.8       Termination
for Abandonment. If Checkpoint Abandons all Licensor Patents in a country, then Licensor may terminate the Agreement with respect
to such country on thirty (30) days’ written notice to Checkpoint.

 

10.9       Effects
of Termination/Expiration.

 

(a)         If
this Agreement is terminated by Checkpoint under Sections 10.3, 10.5 or 10.7, or by Licensor under Sections 10.3, 10.4, 10.6 or
10.8, with respect to one or more Licensed Products (“Terminated Products”), in all or any countries of the Territory
(the “Terminated Country(ies)”):

 

(i)       Any and all licenses
granted by Licensor to Checkpoint under this Agreement with respect to the Terminated Products shall terminate in their entirety
or with respect to the Terminated Country(ies), as the case may be, on the effective date of such termination;

 

(ii)      Upon Licensor’s
written request, Checkpoint shall transfer the following assets (collectively, the “Transferred Product Assets”)
to Licensor without charge (except as provided in Section 10.9(c), below), provided that Licensor shall be responsible for all
of costs and expenses incurred by Checkpoint in connection with such transfer:

 

    	 	34	 

     

    

 

(1)       Checkpoint
shall promptly transfer to Licensor, at Licensor’s expense, copies of all data, reports, records and documentation and materials
that both (i) it Controls and (ii) relate solely to the unit of the Terminated Product that contains no active ingredients other
than Compounds (“Covered Product”) (e.g. a tablet that contains other active ingredients would not be a distinct unit
but if the Terminated Products consisted of two tablets one could be a distinct unit), in such Terminated Country(ies), provided
that Checkpoint shall redact information to the extent possible not relating to the Compound or Covered Product;

 

(2)       Checkpoint
shall, to the extent transferable, assign and transfer to Licensor all of its and its Affiliates’ right, title and interest
in and to all Regulatory Approvals and Drug Approval Applications and Regulatory Filings that it solely owns, prepared (whether
completed or partially completed), filed and/or granted solely for terminated Compounds and Covered Products in such Terminated
Country(ies), and Checkpoint shall promptly file with any applicable Regulatory Authority notice of such transfer and assignment;

 

(3)       Checkpoint
shall, to the extent of its Control, transfer to Licensor all relevant records and materials in Checkpoint’s possession containing
Confidential Information relating solely to the terminated Compounds and Covered Product in such Terminated Country(ies), provided,
however, that Checkpoint may keep one copy of such Confidential Information for archival purposes only and such Confidential Information
shall be Confidential Information of Licensor;

 

(4)       To
the extent Checkpoint solely owns any right, title and interest in any Trademarks, trade names and/or logos under which only the
terminated Covered Product has been or is being marketed or sold in the Terminated Country(ies) (excluding for avoidance of doubt
the Checkpoint’s or its Affiliates corporate Trademarks), or internet domain registrations for any such Trademarks or tradenames
(excluding for avoidance of doubt domain name registrations incorporating the Checkpoint’s or its Affiliates corporate Trademarks
(in whole or in part)), Checkpoint shall assign the same to Licensor;

 

(iii)     At Licensor’s
request, Checkpoint shall assign to Licensor, any clinical trial agreements (to the extent assignable without the written consent
of the other parties to such clinical trial agreements) with respect solely to such terminated Compound and Licensed Product in
such Terminated Country(ies), provided that Licensor agrees to assume all liabilities under such clinical trial agreements pursuant
to a form of assumption agreement mutually agreed upon by Licensor and Checkpoint.;

 

(iv)     Any transfers
under this Section 10.9(a) shall be transferred on an “as-is” basis, and all documents and information transferred
to Licensor, to the extent solely related to the terminated Licensed Product or Compound, shall be deemed Licensor’s Confidential
Information;

 

(v)      Checkpoint’s
and Licensor’s restrictive covenants in Sections 2.5 (except if termination is pursuant to Section 10.8) shall
terminate with respect to the terminated Licensed Product in such Terminated Country(ies); and

 

    	 	35	 

     

    

 

(vi)     If at the
time of such termination or thereafter, no license granted by Checkpoint or its Affiliates under the Development Inventions or
Development Patents to a Sublicensee under a Sublicense agreement (or options to acquire such a license) is in effect with respect
to (A) a Terminated Product, (B) a Terminated Country or (C) a Terminated Product in a Terminated Country, then upon Licensor’s
written request to Checkpoint, Checkpoint, on behalf of itself and its Affiliates, shall grant, and shall be deemed to have granted
without further action required, to Licensor and its Affiliates an exclusive royalty-bearing (as provided in Section 10.9(c), non-transferable
(except in connection with an assignment of this Agreement permitted pursuant to Section 12.2), sublicensable, perpetual license
or sublicense (with respect to rights licensed by Third Parties to Checkpoint), under all Development Inventions and Development
Patents Controlled by Checkpoint, to Develop and Manufacture, in the case of (A) above, the Terminated Product in the Territory,
in the case of (B) above the Terminated Product or Licensed Product in the Terminated Countries, and in the case of (C) above,
the Terminated Product in the Terminated Countries.

 

(b)         If
this Agreement is terminated by Checkpoint under Section 10.2 or if this Agreement is terminated by Licensor under Section
10.2, then in addition to any other remedies available to such Party:

 

(i)       All licenses granted
by Checkpoint to Licensor under this Agreement shall terminate; and

 

(ii)      All licenses granted
by Licensor to Checkpoint shall terminate.

 

(c)         If
this Agreement is terminated by Fortress under Section 10.7, or by Licensor under Sections 10.6 or 10.8, in each case, with respect
to a Terminated Product or Terminated Country or in its entirety, then following issuance of a request under Sections 10.9(a)(ii),
10.9 (a)(iii) or 10.9(a)(vi), Licensor shall pay Checkpoint (x) *% of Sublicensing
Royalty Revenue (as defined below), but in no event greater than the royalties that would be payable by Licensor pursuant to the
royalty rates provided below in this Section 10.9(c) (applying such rates to Net Sales by Existing Sublicensees (as defined below)),
and (y) a royalty (the “Reverse Royalty”) on Net Sales of Licensed Products (expressly excluding Net Sales by
Existing Sublicensees) during the Reverse Royalty Term (as defined below) as follows:

 

(i)          if the
termination occurs before completion (where “completion” means receipt of a final study report meeting the guidelines
of the International Conference on Harmonization) of a Phase III Study for a Licensed Product, then * percent (*%)
royalty on Net Sales;

 

(ii)        if the
termination occurs after completion (where “completion” means receipt of a final study report meeting the guidelines
of the International Conference on Harmonization) of a Phase III Study for a Licensed Product but before approval of an NDA or
BLA for such Licensed Product in such country, then a * percent (*%) royalty on Net Sales; or

 

(iii)       if
the termination occurs after approval of an NDA or BLA for a Licensed Product, then a * percent (*%) royalty
on Net Sales.

 

 

* Confidential material redacted
and filed separately with the Commission.

 

    	 	36	 

     

    

 

“Reverse Royalty
Term” means, and determined on a Licensed Product-by-Licensed Product and country-by-country basis, the period commencing
from the First Commercial Sale of a given Licensed Product in such country and ending on the expiry of the last-to-expire Licensor
Patent containing a Valid Claim Covering such Licensed Product in such country

 

For purposes of this Section
10.9(c), the definition of “Net Sales,” and Sections 5.4 through 5.9 shall apply mutatis mutandis to the calculation,
payment, recording, and auditing of Licensor’s obligations to pay Reverse Royalties under this Section 10.9 as they apply
to Checkpoint and, solely for such purpose, each reference in each such Section (and any related definitions) to Checkpoint shall
be deemed to be a reference to Licensor, and (y) a Sublicensee shall be deemed to be a reference to a licensee or sublicensee of
Licensor or any of its Affiliates (and expressly excluding Existing Sublicensees) with respect to the Licensed Product. Notwithstanding
the foregoing, no Reverse Royalty shall be due or payable by Licensor relating to Net Sales of Sublicensees under any Sublicense
in effect at the date of termination of this Agreement (Sublicensees under such Sublicenses, “Existing Sublicensees”).
“Sublicensing Royalty Revenue” means sales-based royalties, and minimum sales royalties, each as actually received
by Jubilant or its Affiliate from an Existing Sublicensee as consideration for the grant of rights to Patent Rights.

 

In no event shall Licensor
transfer (i) its, right, title or interest in Patent Rights Covering a terminated Compound or Licensed Product or (ii) any of the
Transferred Assets, unless the assignee assumes Licensor’s obligations to pay royalties under this Section 10.9 pursuant
to a commercially reasonable assignment and assumption agreement providing that (x) Checkpoint is a third party beneficiary to
such agreement for the purpose of enforcing such payment obligations and (y) any further assignment by such assignee is subject
to the requirements set forth in this paragraph.

 

(d)          Articles I
(Definitions), VI (Patents and Infringement), VII (Confidentiality), IX (Indemnification; Limitation of Liability; Insurance),
XI (Dispute Resolution) and XII (Miscellaneous Provisions) and Section 2.5 (but only with respect to Checkpoint in connection with
a termination under Section 10.8), Sections 5.1, 5.3(b), 5.5 (Royalty Reports and Records Retention), 5.6 (Audits), 5.8 (Late
Payments), 5.9 (Taxes) and 10.9 (Effects of Termination/Expiration) hereof shall survive the expiration or termination of this
Agreement for any reason. A termination of any Compound from this Agreement shall also terminate the related Licensed Product and
termination of any Licensed Product shall terminate the related Compound

 

(e)         Termination
or expiration of this Agreement shall not relieve the Parties of any liability that accrued hereunder before the effective date
of such termination or expiration. In addition, termination or expiration of this Agreement shall not preclude either Party from
pursuing all rights and remedies it may have hereunder or at Law or in equity with respect to any breach of this Agreement nor
prejudice either Party’s right to obtain performance of any obligation.

 

    	 	37	 

     

    

 

(f)          Effect
on Sublicenses.

 

(i)       Upon the termination
of this Agreement in its entirety, each Sublicense which provides for its survival upon such termination shall survive such termination
(but in no event for longer than the period Checkpoint’s licenses hereunder would have been in effect had termination not
occurred) and remain in full force and effect, with Licensor as the Sublicensee’s direct licensor solely with respect to
the Licensor Technology (“Surviving Sublicense”). Upon Licensor’s written request, provided that a Surviving
Sublicense does not include licenses to products other than Licensed Products, Checkpoint shall assign a Surviving Sublicense to
Licensor. If a Surviving Sublicense includes licenses to products other than Licensed Products, Checkpoint shall require that the
terms of such Surviving Sublicense permits the assignment in part to Licensor relating to the Licensor Technology and shall, upon
Licensor’s written request, assign to Licensor the portion of such Surviving Sublicense pertaining to the Licensor Technology.

 

(ii)      Upon the termination
of this Agreement with respect to a Terminated Product in a Terminated Country, each Sublicense that includes such Terminated Product
in such Terminated Country which provides for its survival upon such termination shall survive such termination (but in no event
for longer than the period Checkpoint’s licenses hereunder would have been in effect had termination not occurred) and remain
in full force and effect, with (i) Licensor as the Sublicensee’s direct licensor solely with respect to the Licensor Technology
and the portion of such Sublicense that includes such Terminated Product in such Terminated Country (“Surviving Partial
Sublicenses”) and (ii) Checkpoint continuing as the Sublicensee’s direct licensor with respect to all other rights
granted under such Sublicense. Upon such termination, Licensor shall be a third party beneficiary of the Surviving Partial Sublicense
with respect to the portion thereof pertaining solely to the Terminated Products in the Terminated Countries. Each Sublicense that
provides for survival as set forth in this Section shall provide for such third party beneficiary status.

 

(iii)     With respect to
each Surviving Sublicense and Surviving Partial Sublicense, in the absence of written notice from Licensor to a Sublicensee under
a Surviving Sublicense or Surviving Partial Sublicense provided within forty five (45) days of the termination of this Agreement
electing to continue the payment terms under such Sublicense, in which case such Sublicense payment terms shall continue, the Sublicensee’s
payment obligations with respect to its exercise of its surviving rights to the Licensor Technology (but not with respect to its
exercise or enjoyment of any other rights or assets) thereunder shall, in lieu of any payment obligations set forth in the Sublicense,
be the corresponding payment obligations set forth in this Agreement, provided that (a) with respect to Milestone Payments under
such Sublicense where such Sublicense is for less than the entire Territory and the Milestone Payment is based on cumulative worldwide
Net Sales, the portion of such Milestone Payment for which such Sublicensee shall be liable shall be such Milestone Payment multiplied
by: (I) cumulative Net Sales in such Sublicensee’s territory (and not worldwide Net Sales) divided by (II) cumulative worldwide
Net Sales and (b) with respect to royalties payable under such Sublicense, if the royalty set forth in such Sublicense is equal
to or greater than five percent (5%) of such Sublicensee’s Net Sales, then such amount shall be payable under such Sublicense
in accordance with the terms thereof (in lieu of any royalty payments pursuant to the terms of Section 5.3(a)), and if such royalty
is less than five percent (5%) of such Sublicensee’s Net Sales, then the royalty payable under such Sublicense shall be the
amounts set forth in Section 5.3(a) (in lieu of any royalty payments pursuant to the terms of such Sublicense) and the royalty
tiers will, for the avoidance of doubt, be achieved based on worldwide Net Sales as calculated in accordance with this Agreement,
and Licensor shall notify such Sublicensee within thirty (30) days following it becoming aware of a Net Sales tier higher than
the then-current Net Sale tier applying to the calculation of royalties pursuant to Section 5.3(a). Notwithstanding the foregoing,
within thirty (30) days after the effective date of termination of this Agreement, Licensor shall have the right to terminate a
Sublicense granted to an Affiliate of Checkpoint.

ARTICLE
XI

DISPUTE RESOLUTION

 

11.1       General.
Licensor and Checkpoint shall endeavor to resolve any claim or controversy arising out of the threatened breach, breach, enforcement,
interpretation, termination or validity of this Agreement informally by good faith negotiation between the senior executives, officers
or management of Licensor and Checkpoint. Either Party may give the other Party written notice of any claim or controversy not
resolved in the normal course of business (the “Disputing Party Notice”). Within thirty (30) calendar days
after the delivery of the Disputing Party Notice, the receiving Party shall submit to the other Party a written response (the “Response”).
The Disputing Party Notice and Response shall include a statement of each Party’s position and a summary of the arguments
supporting that position. Within thirty (30) days after the Disputing Party Notice, such designated senior executives, officers
or management of Licensor and Checkpoint shall meet at a mutually acceptable time and place and thereafter as often as they reasonably
deem necessary to attempt to resolve the claim or controversy. If such efforts do not result in mutually satisfactory resolution
of the dispute, the matter shall be referred to the chief executive officers of Licensor and Checkpoint, or their designees. The
chief executive officers, or their designees, as the case may be, shall negotiate in good faith to resolve such dispute in a mutually
satisfactory manner for up to thirty additional (30) days, or such longer period of time to which the chief executive officers
may agree. All negotiations pursuant to this Article 11 are confidential and without prejudice and shall be treated as compromise
and settlement negotiations for purposes of applicable rules of evidence. If the chief executive officers, or their designees,
as the case may be, are unable to determine a resolution in the time frame set forth above, the matter may be resolved through
arbitration in accordance with the provisions set forth in Section 11.2, in the event of a Technical Dispute or Section 11.3,
in the event of other disputes, as applicable, upon notice by a Party on the other Party specifically requesting such arbitration.
This Article 11 shall not prohibit a Party from seeking injunctive relief from a court of competent jurisdiction in the event
of a breach or prospective breach of this Agreement by any Party which would cause irreparable harm to the other Party.

 

11.2       Technical
Disputes. In the event a dispute over (i) whether a Milestone has been achieved, (ii) whether Checkpoint has used Commercially
Reasonable Efforts to Develop the Licensed Product, (iii) whether Licensor has met its obligations under the Work Plan, (iv) the
proper allocation of Net Sales to a Licensed Product where the Licensed Product is sold as part of a Combination Product, or (v)
the Combination Percentage (each, a “Technical Dispute”) is not resolved in accordance with the negotiation
and mediation dispute resolution processes described in Section 11.1 above, then either Party may submit the matter to expert
intervention in accordance with this Section 11.2. Any such intervention may be initiated by a Party by written notice to
the other Party specifying the subject of the requested intervention. The Technical Dispute hearings shall be convened in New York,
New York and shall be resolved by one expert, to be mutually selected by the Parties; or if the Parties fail to agree on the expert
within ten (10) business days following the date of such written notice, then the Parties shall cause their respective nominees
to select a third individual within ten (10) business days to serve as the expert (the “Expert”). The Expert
shall be required to have pharmaceutical industry experience specifically related to conducting formulation development activities
and clinical trials, and shall not be any employee, agent or consultant of any Party or an Affiliate of any Party at such time,
or otherwise involved (whether by contract or otherwise) in the affairs of any Party at such time. Each Party simultaneously shall
submit to the Expert its proposal with respect to its position on the resolution of the Technical Dispute without having seen the
other Party’s proposal, along with a discussion document explaining the rationale therefor. The Expert shall have the right
to meet with the Parties, either alone or together, and shall have the right to request additional information and documents from
each Party. The Expert shall select only one of the Parties’ proposals based on the Expert’s determination of which
proposal is more consistent with the Expert’s opinion on the resolution of the Technical Dispute (and consistent with the
terms of this Agreement), and shall provide a brief written rationale for such selection. The Expert’s decision shall be
final and shall be binding upon the Parties under this Agreement. The Parties shall submit their documentation to the Expert within
fifteen (15) days of selection of the Expert and provide any requested additional information and documents within ten (10) days
of such request. The Expert shall make his or her decision within fifteen (15) days of such submission (extended by the Expert

11.3       Other
Disputes. Where a Party has served a written notice upon the other requesting arbitration of a dispute that is not subject
to Section 11.2, any such dispute shall be submitted to final and binding arbitration under the then current commercial arbitration
rules of the American Arbitration Association (the “AAA”) in accordance with this Section 11.3. The place
of arbitration of any dispute shall be New York, New York. Such arbitration shall be conducted by one (1) arbitrator mutually
agreed by the Parties but if such agreement cannot be reached within ten (10) days of the commencement of the arbitration,
then an arbitrator appointed by the AAA. The arbitrator shall be a person with relevant experience in the pharmaceutical industry.
The arbitration proceeding shall be held as soon as practicable but in any event within ninety (90) days of appointment of
the arbitrator. Any award rendered by the arbitrators shall be final and binding upon the Parties. Judgment upon any award rendered
may be entered in any court having jurisdiction, or application may be made to such court for a judicial acceptance of the award
and an order of enforcement, as the case may be. The arbitrator shall render a formal, binding, non-appealable resolution and award
as expeditiously as possible, but not more than thirty (30) days after the hearing. Each Party shall pay its own expenses
of arbitration, and the expenses of the arbitrator shall be equally shared between the Parties unless the arbitrators assess as
part of their award all or any part of the arbitration expenses of a Party (including reasonable attorneys’ fees) against
the other Party. A Party may make application to the Arbitrator for the award and recovery of its fees and expenses (including
reasonable attorneys’ fees).

other Party in any way whatsoever including, without limitation, the making of any agreement, representation or warranty and each
Party agrees to not purport to do so.

 

12.2       Assignment.
Neither Party may assign this Agreement, or any of its rights or obligations hereunder without the other Party’s prior
written consent, provided that each Party will, notwithstanding anything to the contrary, be entitled, without the other Party’s

all of such Party’s assets or business (or that portion thereof related to the subject matter of this Agreement) to a Third
Party, (ii) in the event of such Party’s merger, consolidation, reorganization, with or into a Third Party, change of control
or similar transaction, with a Third Party, or (iii) to an Affiliate of such Party, provided that in the case of an assignment
to an Affiliate, the assigning Party shall remain primarily liable for the obligations of such Affiliate except where the non-assigning
Party provided its prior written consent to such assignment, such consent to not be unreasonably withheld or delayed (in which
case the assigning Party shall not remain primarily liable). Any permitted assignee of either Party will, as a condition to such
assignment, assume all obligations of its assignor arising under this Agreement following such assignment. Any purported assignment

interference with its activities), and shall use Commercially Reasonable Efforts to overcome the difficulties created thereby and
to resume performance of its obligations hereunder as soon as practicable, and the time for performance shall be extended for a
number of days equal to the duration of the force majeure. The Party not subject to the Force Majeure Event may terminate this

and agreement of the Parties respecting the subject matter hereof and cancel and supersede any and all prior or contemporaneous
negotiations, correspondence, understandings and agreements between the Parties, whether oral or written, regarding such subject
matter (provided, that any and all previous nondisclosure/nonuse obligations are not superseded and remain in full force and effect
in addition to the nondisclosure/nonuse provisions hereof and matters disclosed under such Agreements shall also be deemed to have
been disclosed hereunder and further provided that the Material Transfer Agreement dated December 28, 2015 between the Parties
shall be deemed terminated immediately prior to entering this agreement, except that any provisions intended to survive such agreement
shall survive, except that a Parties’ rights under this Agreement shall supersede any conflicting provisions of such Material
Transfer Agreement. Each Party acknowledges that it has not relied, in deciding whether to enter into this Agreement on this Agreement’s
expressly stated terms and conditions, on any representations, warranties, agreements, commitments or promises which are not expressly
set forth within this Agreement. No modification or amendment of any provision of this Agreement shall be valid or effective unless
made in a writing referencing this Agreement and signed by a duly authorized officer of each Party.

 

12.6       Governing
Law. This Agreement shall be governed by and interpreted in accordance with the laws of the State of New York, excluding application
of any conflict of laws principles. With respect to docketing an arbitration award or seeking injunctive relief, each Party (a) irrevocably
submits to the exclusive jurisdiction in the United States District Court for the Southern District of New York located in New
York, New York and any State courts sitting in New York, New York (collectively, the “Courts”), and (b) agrees
not to raise any objection at any time to the laying or maintaining of the venue of any such action, suit or proceeding in any
of the Courts, irrevocably waives any claim that such action, suit or other proceeding has been brought in an inconvenient forum
and further irrevocably waives the right to object, that such Courts do not have any jurisdiction over such Party. The United Nations

12.8       Waiver.
No waiver of any provision of this Agreement shall be valid or effective unless made in a writing referencing this Agreement
and signed by a duly authorized officer of the waiving Party. A waiver by a Party of any of the terms and conditions of this Agreement
in any instance shall not be deemed or construed to be a waiver of such term or condition for the future, or of any other term
or condition hereof.

 

12.9       Rights
and Remedies are Cumulative. Except to the extent expressly set forth herein, all rights, remedies, undertakings, obligations
and agreements contained in or available upon violation of this Agreement shall be cumulative and none of them shall be in limitation
of any other remedy or right authorized in law or in equity, or any undertaking, obligation or agreement of the applicable Party.

 

12.10     Severability.
This Agreement is severable. When possible, each provision of this Agreement will be interpreted in such manner as to be effective
and valid under applicable Law, but if any provision of this Agreement is held to be to any extent prohibited by or invalid under
applicable Law, such provision will be ineffective only to the extent of such prohibition or invalidity, without invalidating the
remainder of this Agreement (or of such provision). The Parties shall make a good faith effort to replace the invalid or unenforceable
provision with a valid one which in its economic effect is most consistent with the invalid or unenforceable provision.

 

12.11     Third
Party Beneficiaries. The terms and provisions of this Agreement are intended solely for the benefit of each Party hereto and
their respective successors or permitted assigns and it is not the intention of the Parties to confer third-party beneficiary rights
upon any other person, including without limitation Sublicensees. If a provision provides a benefit to a Sublicensee or indemnitee,
such benefits can only be enforced through a Party or by a separate agreement between such Person and the Party or Parties providing
the benefit.

 

12.12     Equitable
Relief. Each Party recognizes that the covenants and agreements herein and their continued performance as set forth in this
Agreement are necessary and critical to protect the legitimate interests of the other Party, that the other Party would not have
entered into this Agreement in the absence of such covenants and agreements and the assurance of continued performance as set forth
in this Agreement, and that a Party’s breach or threatened breach of such covenants and agreements may cause the opposed
Party irreparable harm and significant injury, the amount of which will be extremely difficult to estimate and ascertain, thus
potentially making any remedy at law or in damages inadequate. Therefore, each Party agrees that an opposed Party shall be entitled
to seek specific performance, an order restraining any breach or threatened breach of Article VII or Section 2.5 and
all other provisions of this Agreement, and any other equitable relief (including but not limited to temporary, preliminary and/or
permanent injunctive relief). This right shall be in addition to and not exclusive of any other remedy available to such other
Party at law or in equity.

 

    	 	43	 

     

    

 

12.13       Interpretation.
The language used in this Agreement is the language chosen by the Parties to express their mutual intent, and no provision
of this Agreement shall be interpreted for or against a Party because that Party or its attorney drafted the provision.

 

12.14     Construction.
The words “include,” “includes” and “including” shall be deemed to be followed by the phrase
“without limitation.” All references herein to Articles, Sections and Schedules shall be deemed references to Articles
and Sections of, and Schedules to, this Agreement unless the context shall otherwise require.

 

12.15     Counterparts.
This Agreement may be executed in counterparts, each of which will be deemed an original, and all of which together will be
deemed to be one and the same instrument. A portable document format (.pdf) copy of this Agreement, including the signature pages,

Joint Press Release

 

Jubilant Biosys Enters into Exclusive out
- Licensing Agreement with Checkpoint Therapeutics for Novel BET Inhibitors

 

Noida (UP), India, and New York, Day,
April XX, 2016

 

Jubilant Biosys Ltd (“Jubilant Biosys”),
a subsidiary of Jubilant Life Sciences Ltd, and Checkpoint Therapeutics, Inc. (“Checkpoint”), a subsidiary of Fortress
Biotech, Inc. (NASDAQ: FBIO), today announced the signing of an exclusive, worldwide license agreement under which Jubilant Biosys
will out-license to Checkpoint a family of patents covering compounds that inhibit BRD4, a member of the BET (Bromodomain and Extra
Terminal) domain for cancer treatment. The deal includes an up-front payment of US$2 million and contingent preclinical, clinical
and regulatory payments including commercial milestones totalling up to US$ 180 million. Jubilant Biosys will also receive research
funding and royalty payments on successful commercialization of the compounds. Checkpoint will assume all further preclinical,
clinical development and commercialization responsibilities.

 

The field of epigenetics as a treatment for
cancer is a rapidly evolving area of focus for the pharmaceutical and biotech industry. Both parties believe that by working together
to further develop these compounds, they will better be able to move towards bringing a product to market that will greatly improve
the lives of patients.

 

Mr. Shyam S. Bhartia, Chairman and Mr. Hari
S. Bhartia, Co-Chairman and Managing Director, of Jubilant Life Sciences, commented, “The Drug Discovery business vertical
under Jubilant Biosys and Jubilant Chemsys has acquired many years of extensive expertise and knowledge working with large pharma
and biotech companies. Jubilant had decided to make strategic investments in proprietary drug discovery of small molecules with
an intent to out-licence the same for upfront payments and phased milestone payments/royalties. This agreement represents our first
out-licensing deal which is a testament to our investment in innovation in the pharmaceutical business.”

 

James F. Oliviero, III, President and CEO of Checkpoint stated,
“We are very pleased to be partnering with Jubilant Biosys to license a family of patents covering compounds that inhibit
BRD4 for cancer treatment.  This agreement enhances our current product portfolio of immuno-oncology and targeted anti-cancer
agents. BET inhibitors have generated significant excitement within the oncology community and Jubilant’s asset provides
us with additional opportunities to explore proprietary combinations and treatment options for patients. We appreciate Jubilant
entrusting our organization to continue development of their exciting technology.”

About Checkpoint Therapeutics

 

Checkpoint Therapeutics, Inc. (“Checkpoint”),
a subsidiary of Fortress Biotech Company, is an immuno-oncology biopharmaceutical company focused on the acquisition, development
and commercialization of novel, non-chemotherapy, immune-enhanced combination treatments for patients with solid tumor cancers. Checkpoint
aims to acquire rights to these technologies by licensing the rights or otherwise acquiring an ownership interest in the technologies,
funding their research and development and eventually either out-licensing or bringing the technologies to market. Currently, Checkpoint
is developing a portfolio of fully human immuno-oncology targeted antibodies generated in the laboratory of Dr. Wayne Marasco,
MD, PhD, a professor in the Department of Cancer Immunology and AIDS at the Dana-Farber Cancer Institute (“Dana-Farber”).
The portfolio of antibodies Checkpoint licensed from Dana-Farber includes antibodies targeting programmed death-ligand 1 (“PD-L1”),
glucocorticoid-induced TNFR related protein (“GITR”) and carbonic anhydrase IX (“CAIX”). Checkpoint plans
to develop these novel immuno-oncology and checkpoint inhibitor antibodies on their own and in combination with each other, as
published literature suggests that combinations of these targets may work synergistically together. Checkpoint has also licensed
and is developing two oral targeted anti-cancer therapies, consisting of a small molecule inhibitor of poly (ADP-ribose) polymerase
(“PARP”) and a small molecule inhibitor of epidermal growth factor receptor (“EGFR”) mutations. Additionally,
Checkpoint will seek to add additional immuno-oncology drugs as well as other targeted therapies to create wholly-owned proprietary
combinations that leverage the immune system and other complimentary mechanisms. Checkpoint is headquartered in New York City.
