under this Agreement, wishes to acquire or license any rights from the other Party in order to pursue Development of Program
Compounds or Optioned Compounds in other therapeutic areas, such as Alzheimer disease, then the Parties shall negotiate in good
faith for an agreement with commercially reasonable terms pursuant to which the requesting Party may acquire the necessary rights
from the other Party to further Research, Develop, Manufacture and Commercialize the relevant Program Compounds or Optioned
Compounds. For clarity, neither Party shall be under any obligation to agree to enter into any such agreement for the grant of any
such rights or licenses to the other Party, beyond the obligation to consider and negotiate any such request in good faith and on
commercially reasonable terms. And a failure to reach an agreement shall not, under any circumstances, constitute a violation and/or
breach of this Agreement by either Party.

11.3.  Access
to Know-How. To the extent not already provided prior to the Effective Date, each Party promptly shall provide to the other
Party access to, and copies of all documents and materials containing, the Selvita Know-How, Felicitex Know-How and Collaboration
Know-How as shall be reasonably requested by the other Party and as necessary or reasonably useful: (a) to exercise its rights
under the license grants in this Agreement or (b) to undertake activities assigned to it under the Research Plan.

 

11.4. 
Section 365(n) of the Bankruptcy Code. All rights and licenses granted under or pursuant to this Agreement by Felicitex
or Selvita are, and shall otherwise be deemed to be, for purposes of Section 365(n) of the U.S. Bankruptcy Code or any analogous provisions
in any other country or jurisdiction, licenses of right to “intellectual property” as defined under Section 101 of the U.S.
Bankruptcy Code. The Parties agree that the Parties, as licensees of such rights under this Agreement, shall retain and may fully exercise
all of their respective rights and elections under the U.S. Bankruptcy Code or any analogous provisions in any other country or jurisdiction.
The Parties further agree that, in the event of the commencement of a bankruptcy proceeding by or against either Party under the U.S.
Bankruptcy Code or any analogous provisions in any other country or jurisdiction, the Party that is not a party to such proceeding shall
be entitled to a complete duplicate of (or complete access to, as appropriate) any such intellectual property and all embodiments of such
intellectual property, which, if not already in the non-subject Party’s possession, shall be promptly delivered to it (a) upon any
such commencement of a bankruptcy proceeding upon the non-subject Party’s written request therefor, unless the Party subject to
such proceeding elects to continue to perform all of its obligations under this Agreement, or (b) if not delivered under clause (a) above,
following the rejection of this Agreement by or on behalf of the Party subject to such proceeding upon written request therefor by the
non-subject Party.

 

11.5.  Buy-Out
Option. Selvita has the right to assume all of Felicitex’s rights (including intellectual property other than Patents or
Know-How Controlled by Affiliates of Felicitex, contractual, development and commercial rights) for any Clinical Candidate for the
one-time milestone payment to Felicitex of [**] at any time after the selection of a Clinical Candidate by the JSC and prior to the
initiation of GLP Toxicology Studies. In such case, Selvita shall be free of all further obligations to Felicitex. Notwithstanding
anything to the contrary herein contained, in the event that Selvita exercises its right set forth in this Section 11.5 and
Felicitex reasonably believes that the Clinical Candidate has a value in excess of [**] dollars, then Felicitex shall have right to
refer the matter to dispute resolution in accordance with Sections 17.1 and 17.2 hereof and the decision of the arbitrator shall be
final and binding, provided however, that under no circumstances can the arbitrator determine that the value of the Clinical
Candidate is less than [**] dollars.

EXCLUSIVITY

 

12.1. Upon the Effective Date and for
a further period of twenty five (25) years after the expiration (but not early termination) of the Term of this Agreement, Selvita shall
not pursue, neither alone nor in collaboration with or through Third Parties, the Research, Development, Manufacturing (for Development
or Commercialization), or Commercialization of any Compounds or therapeutic products selective against the Target. In case of early termination
of this Agreement by either Party without the exercise of an Option by Felicitex, Selvita’s exclusivity obligation under this Article
12 shall also terminate upon the effective date of any such early termination without any further applicable restrictions and limitations
for Selvita. As used herein, “Compounds selective against the Target” shall mean a Compound having an activity against
the Target of not more than 400 nM, as measured by the concentration sufficient to inhibit the activity of the Target by 50% (“IC50”)
in an in vitro kinase assay known as “ADP-GloTM system,” available from Promega, Catalog No: V9101-V9103 and
wherein such Compound possesses at least 10-fold higher activity against the Target, measured by the IC50 values, than against other
kinases.

 

12.2. 
Felicitex’s Exclusivity. During the Term of this Agreement, Felicitex shall not undertake, neither alone nor in collaboration
with or through Third Parties, any work on medicinal chemistry for Compounds selective against the Target outside the scope of this Agreement.
In the event that Felicitex exercises its Option, Felicitex shall be entitled to continue its work on medicinal chemistry for Compounds
selective against the Target either by itself or through an Affiliate, Engaged Person, other Sublicensee or other Third Party, in each
case in accordance with the provisions of the Exclusive License Agreement, it being understood that such continuing work of Felicitex
shall not be considered a breach of this Section 12.2 (even if the Term of this Agreement and the term of any Exclusive License Agreement
are overlapping). As used herein, “Compounds selective against the Target” shall mean a Compound having an activity
against the Target of not more than 400 nM, as measured by the concentration sufficient to inhibit the activity of the Target by 50% (“IC50”)
in an in vitro kinase assay known as “ADP- GloTM system,” available from Promega, Catalog No: V9101-V9103 and
wherein such Compound possesses at least 10-fold higher activity against the Target, measured by the IC50 values, than against other kinases.

 

For the purposes
of this Agreement, “medicinal chemistry” shall mean design and synthesis of a Compound that was first synthesized, described
or publically disclosed after the Effective Date of this Agreement. For the avoidance of doubt, the term “medicinal chemistry”
does not include: synthesis or manufacturing of a compound known to Felicitex, Selvita or a Third Party on the Effective Date of this
Agreement, preparation and testing of salt forms of such a compound, evaluation of solid state properties of such a compound, preparation
and testing of solid forms (amorphous or polymorphs) of such a compound, pre-formulation and formulation development activities and stability
studies of such a compound, development of analytical or bioanalytical methods, or development of a pharmaceutical composition comprising
such a compound, including storage formulations or dosing formulations that include such a compound.

 INDEMNIFICATION; INSURANCE

 

15.1. 
Indemnification. Each Party (each a “Indemnifying Party”) shall indemnify, defend and hold harmless the
other Party and its Affiliates, and its and their respective directors, officers, employees and agents (each a “Indemnified Party”),
from and against any and all liabilities, damages, losses, costs and expenses, including the reasonable fees of attorneys and other professional
Third Parties (collectively, “Losses”), arising out of or resulting from any and all Third Party suits, claims, actions,
proceedings or demands (“Claims”) based upon:

 

(a) 
the negligence, recklessness or wrongful intentional acts or omissions of the Indemnifying Party or its Affiliates or its Sublicensees
and its or their respective directors, officers, employees and agents, in connection with the Indemnifying Party’s performance of
its obligations or exercise of its rights under this Agreement;

 

(b) 
any breach of any representation or warranty or covenant made by the Indemnifying Party under Article 14 or any other provision
under this Agreement;

 

(c) 
the Research and Development of Program Compounds that is actually conducted by or on behalf of the Indemnifying Party, its Affiliates
or Sublicensees, the handling and storage by or on behalf of the Indemnifying Party, its Affiliates or Sublicensees of any chemical agents
or other compounds for the purpose of conducting Research or Development by or on behalf of the Indemnifying Party, its Affiliates or
Sublicensees, including any product liability, personal injury, property damage or other damage; or

 

(d) 
any gross negligence, recklessness, wrongful intentional act or omission, failure to comply with any Law, breach of any agreement
with a Third Party, or infringement of Patent or other intellectual property rights of any Third Party by the Indemnifying Party, its
Affiliates or Third Party sublicensees with respect to any Research on any Program Compounds anywhere in the world prior to the Effective
Date or with respect to the Research and Development of Program Compounds under this Agreement;

 

in each case, provided that,
such indemnity shall not apply to the extent that the Indemnified Party itself has an indemnification obligation pursuant to this Section
for such Loss, in which event each Party shall indemnify the other to the extent of their respective liability for such Loss.

 

 15.2. Procedure.

 

15.2.1. 
Notice of Claim. An Indemnified Party seeking indemnification under this Article 15 shall give prompt written notification
to the Indemnifying Party of the Third Party Claim for which indemnification may be sought (it being understood and agreed, however, that
the failure by an Indemnified Party to give notice of a Third Party Claim as provided in this Section shall not relieve the Indemnifying
Party of its indemnification obligation under this Agreement except and only to the extent that such Indemnifying Party is actually prejudiced
as a result of such failure to give notice).

 

    - 39 - 

    	

    

 

15.2.2.  Assumption
of Defense; Participation. Within ninety (90) days after delivery of such notification, the Indemnifying Party may, upon written
notice thereof to the Indemnified Party, assume control of the defense of such Third Party Claim with counsel reasonably
satisfactory to the Indemnified Party. If the Indemnifying Party does not assume control of such defense, the Indemnified Party
shall control such defense and, without limiting the Indemnifying Party’s indemnification obligations, the Indemnifying Party
shall reimburse the Indemnified Party for all costs and expenses, including reasonable attorneys’ fees and disbursements,
incurred by the Indemnified Party in defending itself within sixty (60) days after receipt of any invoice therefore from the
Indemnified Party. The Party not controlling such defense may participate therein at its own expense; provided, however, that,
if the Indemnifying Party assumes control of such defense and the Indemnified Party in good faith concludes, based on written advice
from outside counsel, that the Indemnifying Party and the Indemnified Party have conflicting interests with respect to such Third
Party Claim sufficiently adverse to make unadvisable the representation by the same counsel of both Parties under Law, ethical rules
or equitable principles, the Indemnifying Party shall be responsible for the reasonable fees and expenses of a single counsel to the
Indemnified Party in connection therewith. The Party controlling such defense shall keep the other Party advised of the status of
such Third Party Claim and the defense thereof and shall consider recommendations made by the other Party with respect thereto.

 

15.2.3. 
Settlements. The Indemnifying Party shall not agree to any settlement of such Third Party Claim or consent to any judgment
in respect thereof that does not include a complete and unconditional release of the Indemnified Party from all liability with respect
thereto, that imposes any liability or obligation on the Indemnified Party or that acknowledges fault by the Indemnified Party, without
the prior written consent of the Indemnified Party.

 

15.3. 
Insurance. Each Party shall maintain, at its cost, self-insurance against liability and other risks associated with its
activities and obligations under this Agreement, in such amounts, subject to such deductibles and on such terms as are customary for a
company such as the respective Party for the activities to be conducted by it under this Agreement. Each Party shall furnish to the other
Party evidence of such self-insurance upon request.

 

15.4. 
LIMITATION OF LIABILITY. EXCEPT FOR A BREACH OF ARTICLE 12 OR ARTICLE 13 OR FOR CLAIMS OF A THIRD PARTY THAT ARE SUBJECT
TO INDEMNIFICATION UNDER THIS ARTICLE 15, NEITHER SELVITA NOR FELICITEX, NOR ANY OF THEIR RESPECTIVE AFFILIATES OR SUBLICENSEES, WILL
BE LIABLE TO THE OTHER PARTY TO THIS AGREEMENT, ITS AFFILIATES OR ANY OF THEIR SUBLICENSEES FOR ANY INDIRECT, INCIDENTAL, CONSEQUENTIAL,
SPECIAL OR PUNITIVE DAMAGES OR LOST PROFITS OR ROYALTIES, LOST DATA OR COST OF PROCUREMENT OF SUBSTITUTE GOODS OR SERVICES, WHETHER LIABILITY
IS ASSERTED IN CONTRACT, TORT (INCLUDING NEGLIGENCE AND STRICT PRODUCT LIABILITY), INDEMNITY OR CONTRIBUTION, AND IRRESPECTIVE OF WHETHER
THAT PARTY OR ANY REPRESENTATIVE OF THAT PARTY HAS BEEN ADVISED OF, OR OTHERWISE MIGHT HAVE ANTICIPATED THE POSSIBILITY OF, ANY SUCH LOSS
OR DAMAGE.

ARTICLE
XVII

 MISCELLANEOUS

 

17.1. 
Dispute Resolution. If a dispute between the Parties arises under this Agreement, either Party shall have the right to refer
such dispute in writing to the respective Executive Officers, and such Executive Officers shall attempt in good faith to resolve such
dispute. If the Executive Officers are unable to resolve a given dispute pursuant to this Section within sixty (60) days after referring
such dispute to the Executive Officers, or sooner if required by the particular circumstances, either Party may elect to have the given
dispute settled by binding arbitration pursuant to Section 17.2.

 

 17.2. Arbitration.

 

17.2.1. 
Arbitration Request. If a Party intends to begin an arbitration to resolve a dispute arising under this Agreement, such
Party shall, within thirty (3) days following the expiration of the sixty (60) day mediation period referred to in Section 17.1 of this
Agreement, provide written notice (the “Arbitration Request”) to the other Party of such intention and a statement
of the issues for resolution. From the date of the Arbitration Request and until such time as the dispute has become finally settled,
the running of the time periods as to which the other Party must cure a breach of this Agreement shall be suspended as to any breach that
is the subject matter of the dispute, however, this Agreement shall remain in full force and effect and the Parties shall continue their
obligations hereunder during the pendency of the arbitration(s). Within thirty (30) days after the receipt of the Arbitration Request,
the other Party may, by written notice, add additional issues for resolution in a statement of counter-issues. Any arbitration pursuant
to this Section will be held in accordance with the International Arbitration Rules of the International Centre for Dispute Resolution
(“ICRD”), the international division of the American Arbitration Association, whereas, to the extent legally permissible,
the procedure agreed in Section 17.2.2 shall be applied.

 

17.2.2.  Arbitration
Procedure. The arbitration shall be held in Boston, Massachusetts, United States unless another location is mutually agreed by
the Parties. The arbitration shall be conducted by a single arbitrator knowledgeable in the subject matter at issue in the dispute
and acceptable to both Parties; provided that, the Parties may by mutual agreement elect to have the arbitration conducted by
a panel of three (3) arbitrators. If the Parties fail to agree on a mutually acceptable arbitrator within thirty (30) days after the
Arbitration Request, then the arbitrator shall be selected by the ICRD. The arbitrator may proceed to an award, notwithstanding the
failure of either Party to participate in the proceedings. The arbitrator shall, within thirty (30) days after the conclusion of the
arbitration hearing, issue a written award and statement of decision describing the essential findings and conclusions on which the
award is based, including the calculation of any damages awarded. The arbitrator shall be limited in the scope of his or her
authority to resolving only the specific matter which the Parties have referred to arbitration for resolution and shall not have
authority to render any decision or award on any other issues. The arbitrator shall be authorized to award compensatory damages, but
shall not be authorized to award punitive, special, consequential, or any other similar form of damages, except as provided in
Section 15.4, or to reform, modify or materially change this Agreement. The arbitrator also shall be authorized to grant any
temporary, preliminary or permanent equitable remedy or relief the arbitrator deems just and equitable and within the scope of this
Agreement, including an injunction or order for specific performance. The Parties hereby expressly agree to waive the right to
appeal from the decisions of the arbitrator, and there shall be no appeal to any court or other authority (government or private)
from the decision of the arbitrator. Judgment on the award rendered by the arbitrator may be enforced in any court having competent
jurisdiction thereof.

 

    - 43 - 

    	

    

 

17.2.3. 
Costs. Each Party shall bear all of its own costs and expenses, including, but not limited to attorneys’ fees, costs,
and disbursements arising out of the arbitration, travel, witness fees, consultants, transcripts and the like, and shall pay an equal
share of the fees and costs of the arbitrator.

 

17.2.4. 
Preliminary Injunctions. Notwithstanding anything in this Agreement to the contrary, a Party may seek a temporary restraining
order or a preliminary injunction from any court of competent jurisdiction in order to prevent immediate and irreparable injury, loss,
or damage on a provisional basis, pending the award of the arbitrator on the ultimate merits of any dispute.

 

17.2.5. 
Confidentiality. All proceedings and decisions of the arbitrator shall be deemed Confidential Information of each of the
Parties, and shall be subject to Article 13.

 

17.3. 
Governing Law. This Agreement and any dispute arising from the performance or breach hereof shall be governed by and construed
and enforced in accordance with the Laws of the State of Delaware excluding any conflicts or choice of law rule or principle that might
otherwise refer construction or interpretation of this Agreement to the substantive law of another jurisdiction. The provisions of the
United Nations Convention on Contracts for the International Sale of Goods shall not apply to this Agreement or any subject matter hereof.

17.5.  Assignment.
Neither Party may assign this Agreement without the consent of the other Party, except as otherwise provided in this Section. Either
Party may assign this Agreement in whole or in part to any Affiliate of such Party without the consent of the other Party; provided
that, such assigning Party provides the other Party with written notice of such assignment, the Affiliate agrees in writing to
assume performance of all assigned obligations, and the assigning Party shall remain primarily liable for the performance of its
obligations under this Agreement by such Affiliate. Further, subject to the remainder of this Section, each Party may assign this
Agreement, and all of its rights and obligations hereunder, without the consent of the other Party, to its successor in interest by
way of an acquisition, merger, consolidation, business combination or in connection with the sale of all or substantially all of its
business, equity securities or assets; provided that, such assigning or transferring Party provides the other Party with
written notice of such assignment and the assignee or transferee agrees in writing to assume performance of all assigned
obligations, and the assigning Party shall remain primarily liable for the performance of the assigned obligations under this
Agreement by such assignee or transferee (except in the case of a merger, sale or acquisition in which it is not the surviving
entity). Any purported assignment in violation of this Section 17.5 shall be null and void.

in Law; war; civil commotion; destruction of production facilities or materials by fire, flood, earthquake, explosion or storm; labor
disturbances; epidemic; and failure of public utilities or common carriers. In such event Selvita or Felicitex, as the case may be, shall
immediately notify the other Party of such inability and of the period for which such inability is expected to continue. The Party giving
such notice shall thereupon be excused from such of its obligations under this Agreement as it is thereby disabled from performing for
so long as it is so disabled for up to a maximum of ninety (90) days, after which time Selvita and Felicitex shall promptly meet to discuss
in good faith how to best proceed in a manner that maintains and abides by the Agreement. To the extent possible, each Party shall use
reasonable efforts to minimize the duration of any force majeure.

 

17.8. Notices.

Exhibit A

 

     

     

    

  

Project Goals

 

The ultimate output of the
Felicitex-Selvita Collaboration is a Clinical Lead Candidate, which is a compound with the appropriate activity and drug-like
properties for progression into the IND-enabling studies, and the discovery of high quality Lead Compounds that are structurally
unrelated (new IP) to the Lead Clinical Candidate.

 

The immediate, short-term goal is the optimization/Development of DYRK1B inhibitors based on the scaffolds identified by Selvita and by Felicitex.

 

Desired target profile of the clinical candidate.

 

		■	Selective and potent DYRK1B
inhibitor:

 

		●	Desired 100:1 inhibitory activity
(IC50 in a biochemical assay) of DYRK1B over DYRK1A;

 

		●	Desired 1000:1 inhibitory activity (IC50 in a biochemical
assay) of DYRK1B over any of the CDKs;

 

		●	Desired 1000:1 inhibitory activity (IC50 in a biochemical assay) of DYRKlB over GSK3f3;

 

		●	High selectivity in the panel of human protein kinases (330+ non-mutant kinases);

 

		●	Low nanomolar activity in a biochemical assay;

 

		●	High nanomolar or single digit micromolar activity in a cell-based assay
in a DYRK1B-expressing cell line, 100:1 ratio of DYRK1B+ versus DYRK1B- cell line;

 

		●	Tumor regression of >40% in three xenograft models;

 

		■	Biopharm aceutical class:

 

		●	Preferably BCS Class 1 compound, class 2 at worst;

 

		●	Oral bioavailability:

 

		-	Absolute oral bioavailability >70% in one rodent and
one non-rodent species;

 

		-	Not a substrate of CYP3A4;

 

		●	Metabolic stability:

 

		-	Half-life >3h in vivo in an animal species with
metabolism of the clinical series compounds most similar to human;

 

		●	High passive permeability:

 

		-	Not a substrate of P-glycoprotein or a related ABC efflux
pump (MDR, etc.);

 

		■	Absence of toxicity flags:

 

		●	No evidence of toxic effects at concentrations ≥30-fold of
projected efficacious concentration from in vitro toxicological profiling: cardiotoxicity by hERG inhibition,inhibition of the
six major CYP450 isoforms, Hep G2, Ames and micronucleus testing;

 

Exhibit A

 

    2

     

    

 

		■	Other

 

		-	No brain penetration, achieved
through appropriately high polar surface area and confirmed in vivo;

 

		-	Plasma protein binding <95%;

 

		-	Low partition into RBCs;

 

		-	Accumulation in the cell nucleus and cytoplasm, avoids lysosomal
                                                               entrapment (not a strongly basic compound);

 

It is understood by both parties that the
final clinical candidate may not meet all of the above criteria. However, if Felicitex decides to pursue any further preclinical
and clinical development of any of the compound identified in the collaboration (according to the agreement), it is assumed that the
clinical candidate criteria where met and Selvita is eligible for milestones and royalties.

Resynthesis of selected SLV (Selvita) compounds.

 

Four compounds were chosen for resynthesis
and they represent both scaffolds. Compounds which will be resynthesized in slightly larger scale (30mg) have shown high inhibitory
activity against DYRK1A kinase (low nanomolar IC50), they are also expected to be strong DYRK1B inhibitors as shown initially by
high % of DYRK1B inhibition. Obtained inhibitors will be retested for kinase inhibitory activity to confirm previously obtained
results.

PROCEDURE FOR CALCULATING STRUCTURAL SIMILARITY

 

Two compounds will be considered as derivatives of each
other if their Stated Similarity Coefficient will be >=0.85.

 

For avoidance of doubt, Stated Similarity Coefficient
will be calculated on neutral compounds except in the case of “onium” compounds, formed by substituents other than hydrogen
(example: benzalkonium chloride).

 

The algorithm to calculate the Stated Similarity Coefficients
is presented below:

 

Proposed is to define
structural similarity basing on the MACCS fingerprint definition used in a public domain chemoinformatics toolkit “Open
Babel” (O’Boyle et al., 2011). Open Babel is an Open Source chemistry toolbox, broadly accepted and used in
chemoinformatics. The examples presented were generated using the Open Babel version 2.3.2 (from 17-02- 2013), downloaded from their
website: http://sourceforge.net/projects/openbabel/

 

MACCS key fingerprint definition contains a
list of SMART queries, and is accessible as a
textfileontheopenbabelinstallationdirectory.OnLinuxitis:
/usr/local/share/openbabel/2.3.2/MACCS.txt.

 

The procedure for the structural similarity
is as follow:

 

		1.	Generate an SDF formatted file with the query compound

 

		2.	Generate an SDF formatted file with the compounds from the
compared library

 

		3.	Run the openbabel fingerprint similarity procedure, with
Tanimoto similarity coefficient, using the command:

 

obabel query.sdf library.sdf –ofpt -xfMACCS

 

where: query.sdf and library.sdf
are the files created in points 1 and 2.

 

		4.	Analyze the output of the program (see example below).

 

Example: Calculating of similarity of Gefitinib (Iressa)
to 20 selected, approved small molecule kinase inhibitors (taken from Figure 1 from the KLIFS article (van Linden, Kooistra, Leurs, de
Esch, & de Graaf, 2013)

Definitions:

 

“Chemical fingerprint”
means a string of binary values (0 or 1) used to characterize a molecule. In the presented definition, MACCS structural fingerprint was
proposed to describe the compared compound. The MACCS definition of structural keys is frequently used in chemoinformatics, because it
allows assigning unambiguously a binary string to the given structure. In the case of other, hashed fingerprints, the particular binary
representation may depend on the algorithm used; therefore, the particular result of comparison may depend on the software used.

 

Exhibit C

 

     

     

    

 

In the presented examples, MACCS
fingerprints are calculated using a publicly accessible program Open Babel. MACCS fingerprint is created using structural key descriptors
in which each bit is associated with a SMARTS pattern.

 

A structural key is a fixed-length
bitstring in which each bit is associated with a specific molecular pattern. When a structural key is generated for a molecule, the bitstring
encodes whether or not these specific molecular patterns are present or absent in the molecule. The performance of such keys depends on
the choice of the fragments used for constructing the keys and the probability of their presence in the searched molecule databases.

 

“SMARTS” means
a language that allows specifying substructures by providing a number of primitive symbols describing atomic and bond properties. Atom
and bond primitive specifications may be combined to form expressions by using logical operators. For more information go to: http://www.daylight.com/dayhtml/doc/theory/theory.smarts.html.

 

“Tanimoto similarity coefficient”
means the most commonly used similarity coefficient in chemical informatics. It is often applied to comparison of binary strings, and
may be calculated using the equation:

 

 

 

where:

a –the number of “on” features (bits) in
structure A)

b – the number of “on” features (bits) in
structure B

c – the number of “on” features (bits)
common to both fingerprints A and B

 

The range of Tanimoto coefficient is from 0 to 1, with
larger values for more similar compounds.

 

Brown and Martin (Brown & Martin,
1997) found that 2D descriptors (in combination with hierarchical clustering) are best at separating actives from inactives, given a particular
target. Structural keys, hashed fingerprints and different 3D descriptors were compared and authors concluded that the MACCS structural
key descriptor implicitly contains a great deal of information relevant to each type of interaction.

“Stated Tanimoto similarity coefficient”–
means Tanimoto coefficient, calculated using MACCS fingerprint representation, is more than 0.85.

Net Sales shall be determined
on, and only on, the first sale by Felicitex or any of its Affiliates to a Third Party (other than a Sublicensee or a distributor). Sales
of an Product between Felicitex and any of its Affiliates for resale shall be excluded from the computation of Net Sales, but the subsequent
resale of such Product to a Third Party (other than a Sublicensee or a distributor) shall be included within the computation of Net Sales.
For the avoidance of doubt: net sales on sales of Products by Felicitex’s or its Affiliates’ Sublicensees or Third Party Partners
(or by their sublicensees or distributors) to other independent or unaffiliated Third Parties are considered “Participation Income”
pursuant to Section 7.3.1 and therefore are not reflected as Net Sales pursuant to this Section 1.46.

 

If a Product under this Agreement
is sold in the form of a Combination Product, then Net Sales for such Combination Product shall be determined on a country-by-country
basis by mutual agreement of the Parties in good faith taking into account the perceived relative value contributions of the Product and
the other ingredient or component in the Combination Product, as reflected in their respective market prices. In case of disagreement,
an independent expert agreed upon by both Parties or, failing such agreement, designated by the International Chamber of Commerce, shall
determine such relative value contributions and such determination shall be final and binding upon the Parties. As used in this Section,
“Combination Product” means an Product that: (a) contains one or more additional active ingredients (whether co-formulated
or co- packaged) that are not Optioned Compounds or (b) is combined with one or more products, devises, pieces of equipment or components.

 

In the event a Product is “bundled”
for sale together with one or more other products in a country (a “Product Bundle”), then Net Sales for such Product
sold under such arrangement shall be determined on a country-by-country basis by mutual agreement of the Parties in good faith taking
into account the relative value contributions of the Product and the other products in the Product Bundle, as reflected in their individual
sales prices. In case of disagreement, an independent expert agreed upon by both Parties or, failing such agreement, the International
Chamber of Commerce shall determine such relative value contributions and such determination shall be final and binding upon the Parties

 

1.47 “Optioned
Compound” means: (a) the Compound(s) listed in Exhibit B; (b) any Derivative, enhancement, refinement, invention or improvement
of any Compound described in clause (a) above that is first synthesized, identified, conceived, reduced to practice or developed by (or

of a Compound described in clause (a) or (b) above.

 

1.48
“Patents” means: (a) all national, regional and international patents and patent applications, including
provisional patent applications, (b) all patent applications claiming priority from any one of the above, including divisionals,
continuations, continuations-in-part, (c) any and all patents that have issued or in the future issue from the foregoing patent
applications ((a) and (b)), including utility models, petty patents and design patents and certificates of invention, (d) any and
all extensions or restorations by existing or future extension or restoration mechanisms, including revalidations, reissues,
re-examinations and extensions (including any supplementary protection certificates and the like) of the foregoing patents or patent
applications ((a), (b), and (c)), and (e) any similar rights, including so-called pipeline protection or any importation,
revalidation, confirmation or introduction patent or registration patent or patent of additions to any of such foregoing patent
applications and patents.

 

1.49 “Person”
means any individual, partnership, joint venture, limited liability company, corporation, firm, trust, association, unincorporated organization,
governmental authority or agency, or any other entity not specifically listed herein.

 

1.50 “Phase
1 Clinical Trial” means a Clinical Trial in which the Product is administered to human subjects at single and multiple dose
levels with the primary purpose of determining safety, metabolism, and pharmacokinetic and pharmacodynamic properties of the Product,
and which is consistent with 21 U.S. CFR § 312.21(a). For the purposes of the milestone payments under this Agreement, a “Phase
1 Clinical Trial” shall be a Clinical Trial which is submitted to the Regulatory Authority as a Phase 0 Clinical Trial, Phase 1
Clinical Trial or as a Phase 1/2 Clinical Trial.

 

Exhibit D

1.51 “Phase
2 Clinical Trial” means a Clinical Trial of the Product in human patients, the principal purposes of which are to make a preliminary
determination that the Product is safe for its intended use, to determine its optimal dose, and to obtain sufficient information about
the Product’s efficacy to permit the design of Phase 3 Clinical Trials, and which is consistent with 21 U.S. CFR § 312.21(b).
For the purposes of the milestone payments under this Agreement, a “Phase 2 Clinical Trial” shall be a Clinical Trial which
is submitted to the Regulatory Authority as a Phase 2 Clinical Trial or as a Phase 2/3 Clinical Trial.

 

1.52 “Phase
3 Clinical Trial” means a Clinical Trial of the Product in human patients, which trial is designed (a) to establish that the
Product is safe and efficacious for its intended use; (b) to define warnings, precautions and adverse reactions that are associated with
the Product in the dosage range to be prescribed; and (c) to be, either by itself or together with one or more other Clinical Trials having
a comparable design and size, the final human Clinical Trial in support of Regulatory Approval of an MAA or NDA of the Product, and (d)
consistent with 21

U.S. CFR § 312.21(c). For
the purposes of the milestone payments under this Agreement, a “Phase 3 Clinical Trial” shall be a Clinical Trial which is
submitted to the Regulatory Authority as a Phase 3 Clinical Trial.

 

1.53 “Product”
means any therapeutic product comprising or based upon an Optioned Compound, whether or not as the sole active ingredient, and in any
dosage form or formulation.

 

1.54 “Prosecution
and Maintenance” or “Prosecute and Maintain” means, with regard to a Patent, the preparation, filing, prosecution
and maintenance of such Patent, as well as re- examinations, reissues, appeals, and requests for patent term adjustments with respect
to such Patent, together with the initiation or defense of interferences, post-grant reviews, Inter Parties Reviews, Ex Parte Reexam,
the initiation or defense of oppositions and other similar proceedings with respect to the particular Patent, and any appeals therefrom.
For clarification, “Prosecution and Maintenance” or “Prosecute and Maintain” shall not include any other defense
or enforcement actions taken with respect to a Patent.

 

1.55 “Regulatory
Approval” means, with respect to a country in the Territory, the approval, license or authorization of the applicable Regulatory
Authority(ies) necessary for the marketing and sale of a pharmaceutical or biopharmaceutical product for a particular indication in such
country in the Territory, including any separate pricing or reimbursement approvals, but only to the extent that such approvals are legally
required for the marketing and sale of a pharmaceutical product for such indication in such country. For the avoidance of doubt:
(a) if the marketing and sale of a pharmaceutical product for a given indication in a given country does not legally require a separate
pricing or reimbursement approval, no such approval is required within this definition and (b) if the marketing and sale of a pharmaceutical
product for a given indication requires more than one separate pricing or reimbursement approval in a given country, the first pricing
or reimbursement approval achieved shall suffice to meet this definition.

COMMERCIAL TERMS

 

7.1 General
Terms for Payments to Selvita with Respect to Optioned Compounds and Products. In consideration of the rights granted to Felicitex
hereunder, Felicitex shall make the following payments to Selvita in accordance with the terms and conditions of this Article 7, whereas
the payment obligations outlined in Section 7.2 apply if and as long as Felicitex undertakes Internal Development and the payment obligations
outlined in Section 7.3 apply if Felicitex undertakes External Development.

 

7.1.1 Initial Value Share.
With view to Selvita’s and Felicitex’s contributions to the Research and Development of the Optioned Compounds the Parties
agree and acknowledge that Selvita’s share in the value of the subject matter of this Agreement amounts to [ ] percent ([% ])
(“Initial Value Share”) [Note to Draft: specific initial value share percentage be completed in final version pursuant
to guidelines for calculation of the initial value share (V1 or V2) in Exhibit F, Part A of the RCO Agreement.].

 

Exhibit D

 

    15 

    	

    

 

7.1.2 Step-Down
Formula. The Parties agree and acknowledge that Felicitex may undertake Development and Commercialization not only with regard to
the Optioned Compounds most advanced as of the Effective Date, but that Felicitex may proceed with the Development and Commercialization
of any other Optioned Compound for which a Patent with a Valid Claim Covering the Development, Manufacture or Commercialization of such
given Optioned Compound may be filed several months after the Effective Date. With a view to Optioned Compounds and only in case that
Felicitex (or its Affiliate or Sublicensee or Third Party Partner, as applicable) files the first Patent with a Valid Claim Covering the
Development, Manufacture or Commercialization of such Optioned Compounds or related Products after 31 January 2019, Selvita’s Initial
Value Share shall be decreased on basis of the following formula (“Decreased Value Share”), whereas the Parties agree
that Felicitex (or its Affiliate or Sublicensee or Third Party Partner, as applicable) shall file such first Patent for a given Optioned
Compound no later than upon the initiation of GLP Toxicology Studies with regard to such Optioned Compound:

 

Decreased
Value Share = [**])*(X-52)/24, where X is the number of months elapsed from 1 October 2014 until the month when the
relevant application for the first Patent on such Optioned Compounds or related Products is filed.

 

Notwithstanding the aforesaid:
If the application for the first Patent on such Optioned Compounds or related Products is filed after 31 January 2021, the Decreased Value
Share is zero percent (0%).

 

For avoidance of doubt: The Step-Down
Formula pursuant to this Section 7.1.2 shall be applied only once to a given Optioned Compound.

 

7.1.3 Value
Share Adjustment. Selvita’s Initial Value Share or, if applicable, Decreased Value Share can be modified by [**] of its
initial value (i.e. it can be [**] or [**] its initial value), if Felicitex’s costs for pre-clinical Development (IND enabling
studies as reflected by invoices from CROs) achieve or exceed [**] Dollars ([**]) or fall below thereof down to [**] U.S. Dollars
(US$ [**] In such case, Selvita’s Initial Value Share, or if applicable, Decreased Value Share shall be recalculated on basis
of the following formula (“Adjusted Value Share”):

 

Adjusted
Value Share (in percent,%) = V - [V [**] *(Y-2)/2)], where Y is the direct, evidenced CRO costs for IND-enabling
studies in Million U.S. Dollars (US$M) and V is the actual Initial Value Share or, if applicable, Decreased Value Share of
Selvita as defined in Section 7.1.1 or, if applicable, Section 7.1.2.

 

7.2 Payments
During Internal Development. If and to the extent that Felicitex undertakes the Development and Commercialization by way of Internal
Development, Felicitex shall make the following milestone and royalty payments to Selvita. The milestone and royalty payments reflect
the Initial Value Share and therefore are subject to adjustments in case that the Decreased Value Share or Adjusted Value Share applies
(any such adjustment to be undertaken pursuant to Section 7.2.1(c), Section 7.2.2(c) and Section 7.2.3(c) below).

 

7.2.1 Development
Milestones for Internal Development. Felicitex shall make the following non-refundable, non-creditable development milestone payments
to Selvita. As soon as Felicitex becomes aware that any of the milestone events outlined below has been achieved with respect to an Optioned
Compound or Product, Felicitex shall promptly inform Selvita about such occurrence.

of the first Phase 3 Clinical Trial or (y) filing of an NDA either in the US, the EU, Japan, or any of the BRIC countries, and, in the
case that the “Initiation of the first Phase 3 Clinical Trial” milestone event is not triggered in the course of Development,
the milestone payment for such milestone event shall become due and payable upon the filing of an NDA either in the US, the EU, Japan,
or any of the BRIC countries; and

 

(iv) the
milestone event “Regulatory Approval in the EU” shall mean Regulatory Approval by EMA or by the European Commission or by
any other Regulatory Authority in one of the Major EU Countries, whichever occurs earlier.

 

 (c) Adjustments.

 

(i) In
case a Decreased Value Share is applicable pursuant to Section 7.1.2, the milestone payment amounts indicated in the Development Milestone
Table shall be recalculated as follows:

 

Milestone payment amount multiplied by the Decreased
Value Share (in percent) and divided by the Initial Value Share (in percent)

 

(ii) In
case an Adjusted Value Share is applicable pursuant to Section 7.1.3, the milestone payment amounts indicated in the Development Milestone
Table shall be recalculated as follows:

 

Milestone payment amount multiplied by the Adjusted
Value Share (in percent) and divided by the Initial Value Share (in percent)

 

7.2.2 Sales
Milestones for Internal Development. Felicitex shall make the following non-refundable, non-creditable sales milestone payments to

 7.2.3 Royalties for Internal Development.

 

(a) Royalty
Rates. During the Royalty Term described below, Felicitex shall pay to Selvita royalties on aggregate Net Sales of Products with the
following royalty rates. [Note to Draft: specific royalty rates to be completed in final version pursuant to guidelines for calculation

	[**]	 	 

 

(b)
Royalty Term. Royalties on Net Sales of a Product at the rates set forth in Section 7.2.3(a) shall become payable upon the First
Commercial Sale of a Product and shall continue to be payable, on a Product-by-Product and country-by-country basis, until expiration
of the last Valid Claim of a Selvita Patent or a Collaboration Patent Covering the Development, Manufacturing or Commercialization of
the Product in the relevant country. If a Patent that is filed after the Effective Date by Felicitex (or its Affiliate or Sublicensee
or Third Party Partner, as applicable) is not a Collaboration Patent, but another Patent Covering the Development, Manufacture or Commercialization
of a given Optioned Compound or Product, then in such case the royalty term shall continue until the expiration of the last Valid Claim
of such Patent and the Parties agree and acknowledge that in such case, upon expiration of the licensed Selvita Patents and Collaboration
Patents, the royalties shall remain payable for the Selvita Know-How and Collaboration Know-How licensed hereunder, but shall be reduced
by [**] to reflect the expiry of the licensed Selvita Patents and Collaboration

Patents.

 

 (c) Adjustments.

 

(i) In
case a Decreased Value Share is applicable pursuant to Section 7.1.2, the royalty rate indicated in Section 7.2.3(a) shall be recalculated
as follows:

 

Royalty rate multiplied by the Decreased Value
Share (in percent) and divided by the Initial Value Share (in percent)

 

(ii) In
case an Adjusted Value Share is applicable pursuant to Section 7.1.3, the royalty rate indicated in Section 7.2.3(a) shall be recalculated
as follows:

 

Royalty rate multiplied by the Adjusted Value
Share (in percent) and divided by the Initial Value Share (in percent)

 

 7.3 Payments in Course of External Development.

 

7.3.1 Participation
Income. If and to the extent that Felicitex undertakes Development and Commercialization of Optioned Compounds or Products through
External Development, Felicitex shall pay to Selvita a participation payment on Participation Income in an amount equal to Selvita’s
Initial Value Share or, if applicable, Decreased Value Share or, if applicable, Adjusted Value Share in such Participation Income. Only
in case of prior Internal Development by Felicitex, under the assumption and condition that Felicitex undertakes investments into the
Research and Development of Optioned Compounds and Products from its own or any of its Affiliates’ own resources, the applicable
Initial Value Share, Decreased Value Share or Adjusted Value Share of Selvita for the Participation Income shall be reduced as described
in Exhibit G (“Diluted Value Share“) according the calculation scheme attached as Exhibit G.

 

“Participation
Income” pursuant to this Section includes all payments payable to Felicitex by such Sublicensee or Third Party Partner in
connection with the rights granted or assigned by Felicitex to such Sublicensee or Third Party Partner to Research, Develop,
Manufacture and Commercialize the Optioned Compounds or Products, including: (a) all upfront payments, (b) all milestone payments,
(c) all royalties (or other recurrent payments calculated on the basis of sales income), (d) all purchase prices and (e) all other
revenues, receipts, monies and the fair market value of other consideration directly or indirectly payable to Felicitex, whether by
way of cash or credit or any benefit, advantage or concession. Participation Income does not include or apply for (u) non-US taxes
which are deducted or paid, but only to the extent that Felicitex is not entitled to a refund of such taxes or duties, (v) sales,
use, and/or value added taxes; (w) refunds or rebates; (x) payments for Research, Development and/or Manufacturing services of
Felicitex acting as a subcontractor or service provider (to the extent that the compensation is for fair market value); (y)
consideration received for the purchase of an equity interest in Felicitex (to the extent that the compensation is for fair market
value) and (z) reimbursement of patent costs of Felicitex. If Optioned Compounds or Products are out-licensed or sold together with
other compounds or products in the same transaction, then the Participation Income calculations will be determined per Optioned
Compound or Product at each component’s fair market value. An exemplary calculation of the participation payment to Selvita is
attached hereto as Exhibit H.

 7.3.2 Further Conditions for Participation Payments.

 

(a) If
the external Development and Commercialization by Felicitex pursuant to Section 7.3.1 commences after the achievement of one or more milestones
by Felicitex in course of an Internal Development, the payment obligations pursuant to Section 7.2 shall apply to such internally achieved
milestones and the payment obligations pursuant to Section 7.3 shall apply to all milestone events occurring after commencement of the
External Development;

 

(b) If
Felicitex undertakes the Development and Commercialization of Optioned Compounds and Products both through Internal Development and External
Development (for example in case of a partial out-licensing for certain indications or for certain territories only), Selvita shall receive
both (i) participation payments on Participation Income with view to the Optioned Compounds and Products which are developed through External
Development and (ii) the milestone and royalty payments pursuant to Section 7.2.1 to Section 7.2.3 with view to the Optioned Compounds
and Products which are developed through Internal Development.

 

(c) The
Diluted Value Share shall apply solely to the calculation of participation payments due by Felicitex to Selvita from External Development
pursuant to Section 7.3. For the avoidance of doubt, the Initial Value Share, Decreased Value Share or Adjusted Value Share, not the Diluted
Value Share, shall apply to other payments due by Felicitex to Selvita from Internal Development.

 

(d)
Felicitex shall promptly notify Selvita about (i) any invoice that Felicitex issues with regard to the Participation Income to its Sublicensee
or Third Party Partner and (ii) any receipt of Participation Income by Felicitex from its Sublicensee or Third Party Partner. Felicitex
participation payments to Selvita pursuant to this Section 7.3 are payable upon the earlier of (x) sixty (60) days after Felicitex’s
issuing an invoice with regard to the respective Participation Income to its Sublicensee or Third Party Partner or (y) thirty (30) days
after the date of the invoice from Selvita which Selvita may issue to Felicitex following Felicitex’ receipt of the Participation
Income by Felicitex.

 

(e) In
the event that the Participation Income payable to Felicitex by a Sublicensee or Third Party Partner does not suffice to result in participation
payments to Selvita that are at least equal to the royalty and milestone payments that Selvita could expect from Felicitex in course of
Internal Development (taking into account the market value of the Optioned Compounds or Products as well as actual sales of Products),
then Selvita shall be entitled to receive minimum royalties from such Sublicensee or Third Party Partner. Felicitex shall procure that
any Sublicensee or Third Party Partner agrees to assume and comply with this payment obligation. If Felicitex’s negotiations with
a Sublicensee or Third Party Partner are hindered, endangered or impaired by this Section 7.3.2(e), Felicitex and Selvita shall meet upon
request of Felicitex and negotiate in good faith an alternative structure which meets both Parties’ economical interests and is
qualified to be more easily accepted by such Sublicensee or Third Party Partner. The minimum royalties shall be calculated on basis of
net sales of Products by such Sublicensee or other Third Party Partner (or any of their affiliates or sublicensees, if applicable) to
Third Party purchasers, it being understood that “net sales” in this context shall be calculated basically in accordance with
the Net Sales definition in this Agreement. The royalty rate for minimum royalties (“Minimum Royalty Rate”) shall be
calculated on basis of the basic minimum royalties table and Selvita’s “Minimum Value Share” as follows:

 

(i)
Basic Minimum Royalties Table [Note to Draft: specific royalty rates to be completed in final version pursuant to the guidelines for
calculation of milestones in Exhibit F, Part D of the RCO Agreement.]

 

	Aggregate Calendar Year Net Sales of

 Products in the Territory (in U.S. Dollars)	 	Royalty Rate
	[**]	 	 
	[**]	 	 
	[**]	 	 

 

 (ii) Calculation Formula:

 

Minimum Royalty Rate = Royalty
rate from Basic Minimum Royalties Table*Vmin/Initial Value Share, where Vmin (Minimum Value Share) is calculated as follows:

 

Minimum
Value Share (Vmin) = V - [V* [**] *(Y-2)/2)], where Y is the direct evidenced CRO cost for IND-enabling studies in
Million U.S. Dollars (US$M) and V is either the Initial Value Share or, if applicable, the Decreased Value Share of Selvita
(whichever was applied for determination of the Basic Milestone Royalties Table in Section 7.3.2(e)(i)).

 

(f) For
the avoidance of doubt: Any reference to Felicitex in this Section 7.3 shall apply accordingly to any of its Affiliates, if the External
Development is not initiated by Felicitex directly, but by any of its Affiliates.

7.4 Market
Price. The Parties unanimously declare that the payments hereunder correspond to the market price as set by the Parties on the basis
of negotiations conducted in good faith, each of the Parties acting independently. The market price set by both Parties provided for in
this Agreement corresponds to fair market prices based on similar transactions in the biotechnology industry. All rights and benefits
inherent in (or attributable to) the transaction under this agreement have been included in the Agreement. The execution of this Agreement
was preceded by the Parties elaborating a thorough analysis of the current situation in the biotech and pharmaceutical industry, with
a special consideration for the scientific characteristics of the target, its therapeutic potential, interest of the potential end customers
and current stage of Research.

 

7.5 Reporting
Obligations. Commencing with the First Commercial Sale of a Product and continuing until the expiration of Felicitex’s
payment obligations under this Article 7, Felicitex (itself or through its Affiliate or Sublicensee or Third Party Partner, as
applicable) shall provide to Selvita written reports outlining all conditions and circumstances which are required or reasonably
useful for Selvita to calculate or audit its payment claims towards Felicitex under this Agreement. Felicitex shall provide such
written reports in reasonable details within sixty (60) days after the end of each Calendar Quarter, in particular outlining: (a)
any milestones achieved by Felicitex, its Affiliates, its Sublicensees or its Third Party Partners, (b) Net Sales of Products on a
product-by-product and country-by-country basis in the Territory invoiced by Felicitex or its Affiliates during the concerned
Calendar Quarter, (c) royalties (or other recurrent payments on basis of sales of Products) invoiced by Felicitex from its
Sublicensees or its Third Party Partners during such Calendar Quarter and (d) upfront payments, milestone payments and any other
consideration invoiced by Felicitex from its Sublicensees or Third Party Partners in such Calendar Quarter. The information
contained in each report under this Section 7.5 shall be considered Confidential Information of Felicitex.

 

 7.6 Accounting; Audit Rights.

 

7.6.1 Record
Keeping. Felicitex agrees to keep, and to require its Affiliates and its Sublicensees and Third Party Partners to keep, full, clear
and accurate records of the underlying data relating to the reports and payments required by Article VII for a minimum period of five
(5) years after the relevant payment is owed pursuant to this Agreement.

 

7.6.2 Auditing.
Felicitex agrees to permit, and to require its Affiliates and, its Sublicensees and Third Party Partners to permit, upon not less
than thirty (30) days’ prior written notice, such books and records, as applicable, to be examined by an independent
accounting firm selected by Selvita and reasonably acceptable to the audited party, for the purpose of verifying reports provided by
Felicitex (or such other party) under this Agreement. Such audit shall not: (a) be performed more frequently than once in any twelve
(12) month period (unless a previous audit during such twelve (12) month period revealed a material discrepancy with respect to such
period), (b) be conducted for any Calendar Quarter more than three (3) years after the end of the Calendar Year of which such
Calendar Quarter is a part or (c) be repeated for any Calendar Quarter, and shall be conducted under appropriate confidentiality
provisions satisfactory to the audited party, for the sole purpose of verifying the accuracy and completeness of all financial,
accounting and numerical information and calculations provided under this Agreement. The independent accounting firm shall have the
right to make copies of relevant portions of the audited party’s books and records; provided that any such copies shall
be the Confidential Information of the audited party, shall be protected by appropriate confidentiality obligations and shall not be
shared with Selvita or any other Person. The independent accounting firm will prepare and provide to Felicitex and Selvita a written
report stating only whether the reports submitted and amounts paid hereunder were correct or incorrect, and the amounts of any
discrepancies. Within thirty (30) days following receipt of such report, any discrepancy amounts (together with accrued interest
calculated in accordance with Section 7.8) shall, in case of underpayments, be paid by the owing Party to the other Party, or, in
case of overpayments, shall be reimbursed by the owing Party to the other Party.

 

7.6.3 Costs
of Examination. Such examination is to be made at the expense of Selvita, except if the results of the audit reveal an
underpayment of royalties, milestone payments or other amounts to Selvita by Felicitex of [**] or more in any calendar year, in
which case the audit fees for such examination shall be paid by Felicitex.

 

7.7 Payments; Conversion. All
payments due under this Agreement shall be made in U.S. Dollars by electronic funds transfer to a bank account designated in writing
in the invoice of the receiving Party. If converted into Euro, the conversion shall be based on the exchange rate applicable at
close of business Boston time at the last Business Day of the preceding Calendar Quarter. Unless otherwise specified in this
Agreement or otherwise agreed by the Parties, each payment hereunder shall be due thirty (30) days after the corresponding invoice
date.

 

Exhibit D

 

    20 

    	

    

 

7.8 Late
Payments. Any amount owed by Felicitex to Selvita under this Agreement that is not paid on or before the date such payment is due
shall bear interest at a rate per annum equal to the lesser of: (a) the prime or equivalent rate per annum quoted by The Wall Street
Journal, Eastern Edition on the first Business Day after such payment is due, plus one hundred basis points and (b) the highest rate
permitted by applicable Law, in either case calculated on the number of days such payments are paid after such payments are due and compounded
monthly.

 

7.9 Withholding
or Other Taxes. The Parties agree to cooperate in good faith to provide one another with such documents and certifications as are
reasonably necessary to enable Felicitex and Selvita to minimize or recover any tax payment. Felicitex may withhold taxes in the event
that revenue authorities within the United States require the withholding of taxes on amounts to be paid hereunder to Selvita under applicable
tax treaties between Poland and the United States, and in any such event Felicitex shall deduct such taxes from such payment and such
taxes shall be paid by Felicitex to the proper taxing authority of the United States on behalf of Selvita (evidence of which payment to
such taxing authority shall be provided promptly by Felicitex to Selvita hereunder). In case that Felicitex, any of its Affiliates, its
Sublicensees or any Third Party Partner undertakes a payment to Selvita from any country outside the United States and such payment triggers
other or additional taxes (including VAT or withholding taxes) than such a payment made from within the United States would have triggered,
then such additional taxes shall be paid to the proper taxing authority outside of the United States by the liable party (whereas, in
case of Selvita, Felicitex, its Affiliate, its Sublicensee or Third Party Partner shall make the tax payment on behalf of Selvita (evidence
of which payment to such taxing authority shall be provided promptly to Selvita)), provided, however, that in any such event Felicitex,
its Affiliates, its Sublicensees or Third Party Partner shall gross-up the relevant payment due to Selvita, so that Selvita receives the
same net amount it would have received had the payment been made from the United States (taking into consideration applicable tax
treaties between the United States and Poland); provided, further, however, that no such gross-up or grossed-up payment shall be
due to Selvita if Felicitex’ headquarters for tax domicile purposes is within the United States.

and each Party hereby waives any right it may have under Laws to require any such consent or accounting.

 

 9.2 Prosecution and Maintenance of Patents.

 

9.2.1 Selvita
Patents. Selvita shall have the sole right (but not the obligation) to Prosecute and Maintain the Selvita Patents; provided however
that if Selvita at any time, and for any reason, elects not to Prosecute and Maintain the Selvita Patents, Selvita shall immediately notify
Felicitex and thereafter Felicitex shall have the right (but not the obligation) to Prosecute and Maintain the Selvita Patents. In the
event that Felicitex elects to Prosecute and Maintain the Selvita Patents, then all cost and expenses associated therewith, on a country
by country basis, shall be paid by Felicitex and offset against any royalties payable by Felicitex to Selvita for sales in such relevant
country. Unless such consultation is prohibited by a Third Party agreement or would otherwise compromise or jeopardize patent strategy
on another Selvita patent or patent application unrelated to this Agreement, Selvita shall provide Felicitex with a reasonable opportunity
to substantively comment on Prosecution and Maintenance of any Selvita Patent which Covers or claims Optioned Compounds prior to
taking material actions (including the filing of initial applications), and will in good faith consider any actions recommended by Felicitex
regarding such Selvita Patents. Felicitex shall have the right to review and make comments on and recommendations in relation to the Prosecution

9.2.2 Felicitex
Patents. Felicitex shall have the sole right (but not the obligation) to Prosecute and Maintain the Felicitex Patents; provided however
that if Felicitex at any time, and for any reason, elects not to Prosecute and Maintain the Felicitex Patents, Felicitex shall immediately
notify Selvita and thereafter Selvita shall have the right (but not the obligation) to Prosecute and Maintain the Felicitex Patents. In
the event that Selvita elects to Prosecute and Maintain the Felicitex Patents, then all cost and expenses associated therewith, on a country
by country basis, shall be paid by Selvita. Unless such consultation is prohibited by a Third Party agreement or would otherwise compromise
or jeopardize patent strategy on another Felicitex patent or patent application unrelated to this Agreement, Felicitex shall provide Selvita
with a reasonable opportunity to substantively comment on Prosecution and Maintenance of any Felicitex Patent necessary for commercialization
of the Optioned Compounds prior to taking material actions (including the filing of initial applications), and will in good faith consider
any actions recommended by Selvita regarding such Felicitex Patents.

 

 9.2.3 Collaboration Patents.

 

(a) Felicitex
shall have the sole right (but not the obligation) to Prosecute and Maintain the Collaboration Patents relating to the Optioned Compounds
or Products. No less than thirty (30) days prior to filing of a Patent, Felicitex shall provide to Selvita a copy of the proposed patent
application for review by Selvita and shall consider in good faith any comments or concerns raised by Selvita within twenty (20) days
following receipt of the patent application. Felicitex shall consult with and keep Selvita informed as to material developments with respect
to the Prosecution and Maintenance of Collaboration Patents, including by providing copies of all substantive office actions or any other
substantive documents that Felicitex receives from any patent office, including notice of all interferences, reissues, re-examinations,
oppositions or requests for patent term extensions. Selvita shall fully cooperate with Felicitex in Prosecution and Maintenance of the
Collaboration Patents.

 

(b) If
Felicitex elects not to file or to continue to Prosecute or Maintain a Collaboration Patent, then it shall notify Selvita in writing at
least ninety (90) days before any deadline applicable to the Prosecution or Maintenance of such Collaboration Patent, as the case may
be, or any other date by which an action must be taken to establish or preserve such Collaboration Patent in such country or possession.
In such case, at Selvita’s request, Selvita shall have the right to pursue the filing or support the continued Prosecution or Maintenance
of such Collaboration Patent in its own name, through patent counsel of Selvita’s choice and at Selvita’s cost and expense,
and in such case the ownership in such Collaboration Patent shall then be assigned to Selvita. Any Collaboration Patent assumed by Selvita
in accordance with the foregoing shall, prospectively from the date of such assumption, be excluded from the Collaboration Patent as defined
under this Agreement. Under Section 9.2.3(b), Selvita shall be likewise entitled to Prosecute and Maintain at its own expense (including,
where possible, in form of a separate Patent, such as a divisional application or a continuation application) any claim to the
subject matter of any Collaboration Patent that was disclosed in such Collaboration Patent but not elected by Felicitex for further Prosecution
and Maintenance.

 

(c) The

9.4.2 Right
to Bring an Action. Felicitex shall have the first right, but not the obligation, to attempt to resolve any infringement or claim,
including by filing an infringement suit, defending against such claim or taking other similar action, with respect to a Collaboration
Patent and to compromise or settle any such infringement or claim. If Felicitex does not intend to prosecute or defend such action, Felicitex
shall inform Selvita without undue delay and Selvita shall have the right, but not the obligation, to resolve any infringement or claim,
including by filing an infringement suit, defending against such claim or taking other similar action, with respect to a Collaboration
Patent and to compromise or settle any such infringement or claim. Upon each Party’s request, the other Party shall immediately

of Amounts Recovered. Any amounts recovered by the Party taking an action pursuant to Section 9.4.2, whether by settlement or judgment,
shall be allocated in the following order: (a) to reimburse the Party taking such action for any costs incurred, (b) to reimburse the
Party not taking but joining such action for its costs incurred in such action; and

 

(c) the
remaining amount of such recovery shall be allocated between the Parties pursuant to Selvita’s Initial Value Share, Decreased Value
Share or Adjusted Value Share (whichever is applicable) and Felicitex’s corresponding value share.

to this Agreement, such Party shall promptly notify the other Party of all details regarding such claim or action that is reasonably available
to such Party.

 

9.5.2 Right
to Defend. Felicitex shall have the right, at its sole expense, but not the obligation, to defend a Third Party action and to compromise
or settle such Third Party action. If Felicitex declines or fails to assert its intention to defend such Third Party action within sixty
(60) days after sending (in the event that Felicitex is the notifying Party) or receipt (in the event that Selvita is the notifying Party)
of notice under Section 9.5.1, then Selvita shall have the right, but not the obligation, to defend such Third Party action. The Party
defending such Third Party action shall have the sole and exclusive right to select counsel for such Third Party action.

obligations or exercise of its rights under this Agreement;

 

Exhibit D

 

    26 

    	

    

 

(b) any
breach of any representation or warranty or covenant made by the Indemnifying Party under Article XI or any other provision under this
Agreement;

 

(c) the
Research, Development, Manufacturing and Commercialization of Optioned Compounds that is actually conducted by or on behalf of the Indemnifying
Party, its Affiliates or Sublicensees the handling and storage by or on behalf of the Indemnifying Party, its Affiliates or Sublicensees
of any chemical agents or other compounds for the purpose of conducting Research or Development or Commercialization by or on behalf of
the Indemnifying Party, its Affiliates or Sublicensees or Third Party Partners, including any product liability, personal injury, property
damage or other damage; or

 

(d) any
gross negligence, recklessness, wrongful intentional act or omission, failure to comply with any Law, breach of any agreement with a Third
Party, or infringement of Patent or other intellectual property rights of any Third Party by the Indemnifying Party, its Affiliates or
Sublicensees with respect to the Research, Development, Manufacturing or Commercialization of any Optioned Compound or Product anywhere
in the world prior to the Effective Date or under this Agreement;

 

in each case, provided that,
such indemnity shall not apply to the extent that the Indemnified Party itself has an indemnification obligation pursuant to this Section
for such Loss, in which event each Party shall indemnify the other to the extent of their respective liability for such Loss.

 

12.2 Indemnification
regarding SEL141 Grant. In case of a breach of Felicitex’s obligations under Section 5.3.1 (Implementation), Section 5.3.2 (Implementation
Statement) or Section 5.3.3 (No Direct Disposal), Felicitex shall indemnify, defend and hold harmless Selvita and its Affiliates from
and against any and all liability, damage, loss, cost or expense (including reasonable attorneys’ fees) (“SEL141 Loss”)
arising out of or resulting from a premature termination of the SEL141 Grant by the Polish Agency for Enterprise Development or by any
other competent governmental authority, to the extent such termination and SEL141 Loss is caused due to a breach by Felicitex of its obligations
under Sections 5.3.1 to 5.3.3. In the event that Selvita receives notice of any breach, threatened breach or violation of SEL141 Grant
by Felicitex, its Affiliates or Sublicensees,, then Selvita shall immediately notify Felicitex and provide Felicitex with the information
needed to cure such breach or threatened breach of the SEL141 Grant.

 

 12.3 Procedure.

 

12.3.1 Notice
of Claim. An Indemnified Party seeking indemnification under this Article 12 shall give prompt written notification to the Indemnifying
Party of the Third Party Claim for which indemnification may be sought (it being understood and agreed, however, that the failure by an
Indemnified Party to give notice of a Third Party Claim as provided in this Section shall not relieve the Indemnifying Party of its indemnification
obligation under this Agreement except and only to the extent that such Indemnifying Party is actually prejudiced as a result of
such failure to give notice).

 

12.3.2 Assumption
of Defense; Participation. Within ninety (90) days after delivery of such notification, the Indemnifying Party may, upon written notice
thereof to the Indemnified Party, assume control of the defense of such Third Party Claim with counsel reasonably satisfactory to the
Indemnified Party. If the Indemnifying Party does not assume control of such defense, the Indemnified Party shall control such defense
and, without limiting the Indemnifying Party’s indemnification obligations, the Indemnifying Party shall reimburse the Indemnified
Party for all costs and expenses, including reasonable attorneys’ fees and disbursements, incurred by the Indemnified Party in defending
itself within sixty (60) days after receipt of any invoice therefore from the Indemnified Party. The Party not controlling such defense
may participate therein at its own expense; provided, however, that, if the Indemnifying Party assumes control of
such defense and the Indemnified Party in good faith concludes, based on written advice from outside counsel, that the Indemnifying Party
and the Indemnified Party have conflicting interests with respect to such Third Party Claim sufficiently adverse to make unadvisable the
representation by the same counsel of both Parties under Law, ethical rules or equitable principles, the Indemnifying Party shall be responsible
for the reasonable fees and expenses of a single counsel to the Indemnified Party in connection therewith. The Party controlling such
defense shall keep the other Party advised of the status of such Third Party Claim and the defense thereof and shall consider recommendations
made by the other Party with respect thereto.

 

12.3.3 Settlements.
The Indemnifying Party shall not agree to any settlement of such Third Party Claim or consent to any judgment in respect thereof that
does not include a complete and unconditional release of the Indemnified Party from all liability with respect thereto, that imposes any
liability or obligation on the Indemnified Party or that acknowledges fault by the Indemnified Party, without the prior written consent
of the Indemnified Party.

 

12.4 Insurance.
Each Party shall maintain, at its cost, self-insurance against liability and other risks associated with its activities and obligations
under this Agreement, in such amounts, subject to such deductibles and on such terms as are customary for a company such as the respective
Party for the activities to be conducted by it under this Agreement. Each Party shall furnish to the other Party evidence of such self-insurance
upon request.

NEGLIGENCE AND STRICT PRODUCT LIABILITY), INDEMNITY OR CONTRIBUTION, AND IRRESPECTIVE OF WHETHER THAT PARTY OR ANY REPRESENTATIVE OF THAT
PARTY HAS BEEN ADVISED OF, OR OTHERWISE MIGHT HAVE ANTICIPATED THE POSSIBILITY OF, ANY SUCH LOSS OR DAMAGE.

to the effective date of such expiration or termination. In addition, termination 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

Majeure. No Party shall be held liable or responsible to the other Party nor be deemed to be in default under, or in breach of any
provision of, this Agreement for failure or delay in fulfilling or performing any obligation (other than a payment obligation) of this
Agreement when such failure or delay is due to force majeure, and without the fault or negligence of the Party so failing or delaying.
For purposes of this Agreement, force majeure is defined as causes beyond the control of the Party, including acts of God; material changes
in Law; war; civil commotion; destruction of production facilities or materials by fire, flood, earthquake, explosion or storm; labor
disturbances; epidemic; and failure of public utilities or common carriers. In such event Selvita or Felicitex, as the case may be, shall
immediately notify the other Party of such inability and of the period for which such inability is expected to continue. The Party giving
such notice shall thereupon be excused from such of its obligations under this Agreement as it is thereby disabled from performing for
so long as it is so disabled for up to a maximum of ninety (90) days, after which time Selvita and Felicitex shall promptly meet to discuss
in good faith how to best proceed in a manner that maintains and abides by the Agreement. To the extent possible, each Party shall use
reasonable efforts to minimize the duration of any force majeure.

 

14.8       Notices.
Any notice or request required or permitted to be given under or in connection with this Agreement shall be deemed to have been sufficiently
given if in writing and personally delivered or sent by, facsimile transmission (receipt verified), or international overnight express
courier service (signature required), prepaid, to the Party for which such notice is intended, at the address set forth for such Party

Procedure
for Calculating Structural Similarity

 

Two
compounds will be considered as derivatives of each other if their Stated Similarity Coefficient will be >=0.85.

 

For
avoidance of doubt, Stated Similarity Coefficient will be calculated on neutral compounds except in the case of “onium” compounds,
formed by substituents other than hydrogen (example: benzalkonium chloride).

 

The
algorithm to calculate the Stated Similarity Coefficients is presented below:

 

Proposed
is to define structural similarity basing on the MACCS fingerprint definition used in a public domain chemoinformatics toolkit “Open
Babel” (O’Boyle et al., 2011). Open Babel is an Open Source chemistry toolbox, broadly accepted and used in chemoinformatics.
The examples presented were generated using the Open Babel version 2.3.2 (from 17-02-2013), downloaded from their website: http://sourceforge.net/projects/openbabel/

 

MACCS
key fingerprint definition contains a list of SMART queries, and is accessible as a text file on the openbabel installation directory.
On Linux it is:

 

/usr/local/share/openbabel/2.3.2/MACCS.txt.

 

The
procedure for the structural similarity is as follow:

 

		1.	Generate
                                            an SDF formatted file with the query compound

 

		2.	Generate
                                            an SDF formatted file with the compounds from the compared library

 

		3.	Run
                                            the openbabel fingerprint similarity procedure, with Tanimoto similarity coefficient, using
                                            the command:

 

obabel
query.sdf library.sdf –ofpt -xfMACCS

where:
query.sdf and library.sdf are the files created in points 1 and 2.

		4.	Analyze
                                            the output of the program (see example below).

Definitions:

 

“Chemical
fingerprint” means a string of binary values (0 or 1) used to characterize a molecule. In the presented definition, MACCS structural
fingerprint was proposed to describe the compared compound. The MACCS definition of structural keys is frequently used in chemoinformatics,
because it allows assigning unambiguously a binary string to the given structure. In the case of other, hashed fingerprints, the particular
binary representation may depend on the algorithm used; therefore, the particular result of comparison may depend on the software used.

 

In
the presented examples, MACCS fingerprints are calculated using a publicly accessible program Open Babel. MACCS fingerprint is created
using structural key descriptors in which each bit is associated with a SMARTS pattern.

 

A
structural key is a fixed-length bitstring in which each bit is associated with a specific molecular pattern. When a structural key is
generated for a molecule, the bitstring encodes whether or not these specific molecular patterns are present or absent in the molecule.
The performance of such keys depends on the choice of the fragments used for constructing the keys and the probability of their presence
in the searched molecule databases.

 

“SMARTS”
means a language that allows specifying substructures by providing a number of primitive symbols describing atomic and bond properties.
Atom and bond primitive specifications may be combined to form expressions by using logical operators. For more information go to: http://www.daylight.com/dayhtml/doc/theory/theory.smarts.html.

 

“Tanimoto
similarity coefficient” means the most commonly used similarity coefficient in chemical informatics. It is often applied to
comparison of binary strings, and may be calculated using the equation:

 

 

 

where:

a
– the number of “on” features (bits) in structure A)

b
– the number of “on” features (bits) in structure B

c
– the number of “on” features (bits) common to both fingerprints A and B

 

The
range of Tanimoto coefficient is from 0 to 1, with larger values for more similar compounds.

 

Exhibit D

 

     

    	

    

 

Brown
and Martin (Brown & Martin, 1997) found that 2D descriptors (in combination with hierarchical clustering) are best at separating
actives from inactives, given a particular target. Structural keys, hashed fingerprints and different 3D descriptors were compared
and authors concluded that the MACCS structural key descriptor implicitly contains a great deal of information relevant to each type
of interaction.

“Stated
Tanimoto similarity coefficient”– means Tanimoto coefficient, ca culated using MACCS fingerprint representation, is more
than 0.85.

Calculation
Scheme for the Diluted Value Share

 

Depending
on the stage of Development at which Felicitex undertakes External Development, Selvita’s Initial Value Share, Decreased Value
Share or Adjusted Value Share, whichever is applicable, shall be diluted pursuant to the following table:

 

	Project progress upon External Development	Felicitex share after dilution of Selvita’s applicable value shares	Selvita’s dilution factor (Vd)
	IND-ready candidate	[**]	[**]
	Drug after successful Phase I	[**]	[**]
	Drug after successful Phase II	[**]	[**]
	Drug after successful Phase III	[**]	[**]
	Approved drug	[**]	[**]

 

Therefore,
the Diluted Value Share shall be determined pursuant to the following table:

 

	Project progress upon External Development	Diluted Value Share (Vf)
	IND-ready
candidate	Initial Value Share, Decreased Value Share or Adjusted Value Share (whichever is applicable) (Va)
	Drug after successful Phase I	Va[**]
	Drug after successful Phase II	Va[**]
	Drug after successful Phase III	Va[**]
	Approved drug	Va[**]

 

Accordingly,
the participation payments on Participation Income payable by Felicitex to Selvita shall be calculated on basis of the calculation formula
below (which takes into account the dilution pursuant to the table above):

 

Participation
Payment = Vf*(Participation Income), where Vf=Va*(Vd[**]%).

undertake Development and Commercialization not only with regard to the Optioned Compounds most advanced at the end of the Research Collaboration,
but that Felicitex may proceed with the Development and Commercialization of any other back-up Optioned Compound for which a Patent with
a Valid Claim Covering the Development, Manufacture or Commercialization of such given Optioned Compound may be filed several months
after the end of the Research Collaboration.

                                                                                                                                                                                                                                      assumption: Selvita’s Initial Value Share is [**] at the end of the Collaboration Period I, 15 months
                                                                                                                                                                                                                                      total

 

		●	Calculation:
                                            In the case that the Research Collaboration is terminated before the end of Collaboration
                                            Period I (before 15 months), the following formula applies to calculating the Initial Value
                                            Share:

 

V
1 = [**]%*(X/15), where X is a number of active collaboration months or the fraction of thereof during the Collaboration
Period I, X<15

 

2. Calculation
Formula 2 – applicable in case that the Research Collaboration is terminated after the Collaboration Period I and during
or until the end of the Collaboration Period II:

 

		●	Basic
assumption: Selvita’s Initial Value Share is [**]% after Collaboration Period I and at the end of Collaboration Period II, 27 months
total

 

     

    	

    

 

		●	Calculation:
                                            In the case that the Research Collaboration is terminated after Collaboration Period I, but
                                            before the end of Collaboration Period II (anywhere between 15 months and 27 months), the
                                            following formula applies to calculating the Initial Value Share:

 

V2 = [**]% - [([**]%)*((X-15)/12)], where X is a number of active collaboration months or the fraction of thereof
in both Collaboration Period I and Collaboration Period II and 15<X<27.

 

The
Initial Value Share (V) is defined by either V1 or V2 depending on the length of the Research Collaboration.
Specific milestone payment amounts and royalty rates resulting from this will be included in the final version of the Exclusive License
Agreement (see below B) and C)).

 

A2.
Step-Down and Decreased Value Share

 

As
stated above, Felicitex may proceed with the Development and Commercialization of certain back-up Optioned Compounds for which a Patent
with a Valid Claim Covering the Development, Manufacture or Commercialization of such back-up Optioned Compound may be filed several
months after the end of the Research Collaboration. Only with view to such back-up Optioned Compounds and related Products and only in
case that the first Patent with a Valid Claim Covering the Development, Manufacture or Commercialization of such back- up Optioned Compounds
or related Products is filed after 31 January 2019, Selvita’s Initial Value Share shall be decreased as follows:

 

		●	Basic
                                            assumption 1: If the first Patent with a Valid Claim Covering the Development, Manufacture
                                            or Commercialization of such back-up Optioned Compound or related Product is filed before
                                            or on 31 December 2016, Selvita’s Initial Value Share (as determined pursuant to A1.
                                            above) shall remain untouched and in such case, no Step-Down shall be applicable.

 

		●	Basic
assumption 2: If the first Patent with a Valid Claim Covering the Development, Manufacture or Commercialization of such back-up Optioned
Compound or related Product is filed after 31 December 2016, but before or on 31 January 2019, Selvita’s Decreased Value Share
(DV) shall be  [**]% (independent of the Initial Value Share determined pursuant to A1. above).

 

		●	Calculation
                                            Formula 3: If the first Patent with a Valid Claim Covering the Development, Manufacture or
                                            Commercialization of such back-up Optioned Compound or related Product is filed after 31
                                            January 2019, the following formula applies to calculating Selvita’s Decreased Value
                                            Share:

 

Decreased
Value Share (DV) = [**]%)*(X-52)/24, where X is the number of months elapsed from 1 October 2014 until the month when the relevant
application for the first Patent on such back-up Optioned Compound or related Product is filed and 52<X<75

 

For
the avoidance of doubt: If the application for the first Patent on such back-up Optioned Compound or related Product is filed after 31
January 2021, the Decreased Value Share (DV) is zero percent (0%).

Table

 

The milestone payment amounts to be included in
the milestone table in Section 7.2.1(a) and Section 7.2.2(a) of the final version of the Exclusive License Agreement for the given Option
Compounds to which such Exclusive License Agreement applies shall be calculated on basis of the following milestone table. The calculation
of the actual milestone payments shall be undertaken by the calculation formula below (the basic milestone payment amounts below shall
be multiplied by the actual Initial Value Share (as determined pursuant to A. above) and divided by [**]%). In detail:

		2.	Calculation
Formula:

 

The
table with actual milestones to be inserted in the final version of the Exclusive License Agreement will be recalculated according to
the formula

 

M
1= Basic Milestones * V/[**]%, where V is either the Initial Value Share (V1 or V2, determined pursuant to A1. above) or, if applicable, the Decreased Value
Share (DV, determined pursuant to A2. above) and where Basic Milestones are taken from the Basic Milestone Table above.

 

     

    	

    

 

Drafting
Guideline:

 

If
a Decreased Value Share can be identified by the Parties prior to finalization of an Exclusive License Agreement (because the first Patent
for the relevant Optioned Compound(s) has been already filed at that future point in time and there are no further (current or future)
Optioned Compounds for which further Patent filings would be possible under such Exclusive License Agreement), the Parties shall calculate
the actual milestones for the tables in Section 7.2.1(a) and Section 7.2.2(a) of the final version of the Exclusive License Agreement
on basis of any applicable value share and in such case, Section 7.2.1(c)(i) and Section 7.2.2(c)(i) shall be deleted in the final version
of the Exclusive License Agreement.

 

If
the Parties cannot identify a Decreased Value Share for all (current or future) Optioned Compounds governed by an Exclusive License Agreement,
the Parties shall calculate the actual royalty rates for the table in Section 7.2.1(a) and Section 7.2.2(a) of the final version of the
Exclusive License Agreement on basis of the Initial Value Share and in such case, Section 7.2.1(c)(i) and Section 7.2.2(c)(i) shall remain
untouched.

 

In
any case, the Step-Down Formula for calculation of a Decreased Value Share shall be applied only once for a given Optioned Compound and
the Parties agree and acknowledge that there shall be no double application of the Step-Down Formula.

 

     

    	

    

 

		C.	Royalty
Rates

 

The
royalty rates to be included in the royalties table in Section 7.2.3(a) of the final version of the Exclusive License Agreement for the
given Option Compounds to which such Exclusive License Agreement applies shall be calculated on basis of the following royalties table.
The calculation of the actual royalty rate shall be undertaken by the calculation formula below (the basic royalty rate below shall be
multiplied by the actual Initial Value Share (as determined pursuant to A. above) and divided by 8.5%). In detail:

 

		1.	Basic

		2.	Calculation
Formula:

 

The
table with actual royalty rates to be inserted in the final version of the Exclusive License Agreement will be recalculated according
to the formula

 

R1 =
Basic royalty rate * V / [**]%, where V is either the Initial Value Share (V1 or V2, determined
pursuant to A1. above) or, if applicable, the Decreased Value Share (DV, determined pursuant to A2. above) and where Basic Royalty
Rate is taken from the Basic Royalties Table above.

 

Drafting
Guideline:

 

If
a Decreased Value Share can be identified by the Parties prior to finalization of an Exclusive License Agreement (because the first Patent
for the relevant Optioned Compound(s) has been already filed at that future point in time and there are no further (current or future)
Optioned Compounds for which further Patent filings would be possible under such Exclusive License Agreement), the Parties shall calculate
the actual royalty rates for the table in Section 7.2.3(a) of the final version of the Exclusive License Agreement on basis of any applicable
value share and in such case, Section 7.2.3(c)(i) shall be deleted in the final version of the Exclusive License Agreement.

 

If
the Parties cannot identify a Decreased Value Share for all (current or future) Optioned Compounds governed by an Exclusive License Agreement,
the Parties shall calculate the actual royalty rates for the table in Section 7.2.3(a) of the final version of the Exclusive License
Agreement on basis of the Initial Value Share and in such case, Section 7.2.3(c)(i) shall remain untouched.

 

In
any case, the Step-Down Formula for calculation of a Decreased Value Share shall be applied only once for a given Optioned Compound and
the Parties agree and acknowledge that there shall be no double application of the Step-Down Formula.

 

     

    	

    

  

		D.	Minimum
Royalties

 

The
minimum royalty rates to be included in the basic minimum royalties table in Section 7.3.2(e) of the final version of the Exclusive License
Agreement for the given Option Compounds to which such Exclusive License Agreement applies shall be calculated on basis of the following
royalties table. The calculation of the actually applicable minimum royalty rate shall be undertaken by the calculation formula below.

to the formula D.2 below.

 

		2.	Calculation
                                            Formula

 

Actual
Minimum Royalty Rate = Basic Royalty rate from basic minimum royalties table*Vmin [**]%, where Vmin (Minimum Value Share) is calculated as
follows:

 

Minimum
Value Share (Vmin) = V - [V [**]*(Y-2)/2)], where Y is the direct evidenced CRO cost for IND-enabling studies in Million U.S.
Dollars (US$M) and V is either the Initial Value Share (V1 or V2, determined pursuant to A1. above) or the
Decreased Value Share (DV, determined pursuant to A2. above).

 

		E.	Calculation
Scheme

 

The
draft Exclusive License Agreement attached to this Agreement as Exhibit D contains further provisions on an “Adjusted Value Share”
(see Section 7.1.3 of the Exclusive License Agreement), on a “Diluted Value Share” (see Section 7.3.1 of the Exclusive License
Agreement) and on a “Minimum Royalty Rate” (see Section 7.3.2(e) of the Exclusive License Agreement). The Parties agree and
acknowledge that these provisions are directed to future developments the result of which cannot be assessed and determined upon finalization
of the Exclusive License Agreement. Therefore, the draft Exclusive License Agreement contains additional calculation formulas in the
relevant Sections and in Exhibit G of the Exclusive License Agreement.

 

     

    	

    

 

For
the sake of clarity the Parties confirm that the calculation formulas in the relevant Sections and in Exhibit G of the Exclusive
License Agreement are drafted on basis of and shall reflect the Parties common business understanding as outlined in the following
Calculation Scheme. The Parties acknowledge that the provisions of the Exclusive License Agreement in connection with parts A to D
of this Exhibit F shall be self-explaining and that the Exclusive License Agreement can be finalized without further evaluation and
consideration of this part E of Exhibit F. This part E of Exhibit F shall serve only as an outline of the commercial background
considerations of the Parties. In case of conflicting terms between the Calculation Scheme below and the provisions of the Exclusive
License Agreement, the Exclusive License Agreement shall prevail, unless otherwise mutually agreed by both Parties:

Share Adjustment (if the cost of pre-clinical development other than $2 M )

 

Selvita
Value Share can be modified by up to [**]% of its initial value ( ie. it can be [**] its initial value) if the cost of
pre-clinical development (IND enabling studies, as reflected by invoices from CROs) goes up to or above US$[**]

 

In
that case, the following formula applies to calculating the value share:

 

ELA

Selvita
adjusted value share % , Va = V - [ V*[**] ( Y- 2 ) / 2 ) ]

 

where
Y is the direct CRO cost for IND- enabling studies, in $M;

Felicitex Therapeutics and Selvita initiate strategic collaboration to target cancer quiescence

 

Cambridge
, MA and Krakow, Poland, [         ] November 2014 - Felicitex Therapeutics, a leader in the diagnostics and development of therapeutics
for quiescent cancers, and Selvita (PL: SLV), the largest drug discovery company in Central and Eastern Europe, announced today that
they have entered into a strategic collaboration to develop breakthrough personalized cancer therapeutics for some of the deadliest and
most resistant cancers, such as pancreatic, colon, ovarian, lung and hematopoietic tumors.

 

During the first phase of the collaboration the companies seek to discover and develop selective inhibitors of the cancer quiescence
target kinase family, in order to generte multiple novel drug candidates against the quiescent cancer cells. The ultimate aim of
the joint project is to deliver clinical candidates for unmet oncology indications. The companies plan joint projects on other
targets related to cancer quiescence in the future.

 

It
is currently well accepted in the scientific community that populations of malignant cells are highly heterogeneous and whereas some
of the cancer cells divide rapidly, some of the cancer cells are quiescent. All currently available cancer chemotherapies target
proliferating cancer cells. Quiescent cancer cells are invulnerable to these treatments because quiescent cells are not dividing.
Moreover, when cancer cells are under stress, such as from chemotherapy, anti-angiogenesis therapy, or radiation, cancer cells
often go to “sleep”, or use quiescent state s a niche to hide. After the completion of treatment, these cells begin
growing again and cause cancer recurrence.

 

Felicitex
Therapeutics’ technology targets quiescent, non-responsive cancer cells with two therapeutically beneficial outcomes – firstly
making cancer cells vulnerable to conventional treatments, and secondly preventing cancer cells from hiding in the quiescent state for
indeterminate period of time and thereby delaying or eliminating cancer recurrence.

 

     

    	

    

 

“Cancer
cell quiescence is a major and as yet unaddressed mechanism of cancer resistance – says Maria Vilenchik, PhD, Founder, Chief
Executive Officer and Scientific Director of Felicitex Therapeutics. At Felicitex we strive to develop treatments for some of the
deadliest and most resistant to therapy cancers, among which pancreatic cancer is particularly vicious. Our collaboration with Selvita
creates the opportunity to identify novel therapeutic solutions and bring hope to cancer patients”.

 

Selvita
is highly experienced in the area drug discovery and particularly in development of kinase inhibitors. Over the last five years, Selvita
has built a premium scientific team with one of the world’s most robust kinase inhibitor discovery platforms.

 

“We
want to partner with best scientific teams in the world in order to explore different approaches against neoplastic processes –
says Pawel Przewiezlikowski, Chief Executive Officer of Selvita. The unique know-how of Felicitex in the area of cancer quiescence
together with scientific expertise of Selvita team will highly increase our chances to develop new highly-differentiated therapeutics.”

 

The
alliance of Felicitex Therapeutics and Selvita allows to combine Felicitex’s experience in targeting cancer quiescence with Selvita’s
significant know how on cancer quiescence target kinases, leading to a potentially breakthrough cooperation and delivery of much needed
effective antineoplastic medicines.

 

“The
primary focus of our R&D efforts is development of personalized targeted therapies that address unmet medical needs in oncology”
– says Krzysztof Brzozka, PhD, Chief Scientific Officer of Selvita. “The collaboration with Felicitex Therapeutics
will be an important part of our strategy of diversified R&D approach and will even more broaden the current pipeline of anticancer
projects that we are involved in.”

 

As
part of the research collaboration Selvita will receive from Felicitex guaranteed research funding and a value share in joint projects
which may in future be monetized through milestone payments from Felicitex or a portion of revenues from programs partnered by Felicitex.
The first committed research period will be 15 months with an option for Felicitex to extend the collaboration for additional 12 months.
Selvita will also receive royalties after the jointly discovered drugs have been approved.

 

Text
to be added in the Polish press release and investor communications only:

 

The
research funding from Felicitex to Selvita will be up to US $585,405 guaranteed until December 2015 and up to US $936,648 optional in
2016.

or received (whether by way of cash or credit or any benefit, advantage or concession) by Felicitex or any of its Affiliates for sales
of Products less the following deductions with respect to such sales that are actually incurred and either included in the billing as
a line item as part of the gross amount invoiced, or otherwise documented as a deduction in accordance with IFRS/GAAP to be specifically
attributable to actual sales of such Product: (i) adequate credits, allowances or customary trade, quantity or cash discounts and refunds,

Felicitex under this Agreement and which in particular comply with the obligations outlined in Section 5.5, 6.2, 7.5, 7.6 and 7.9;
and

 

(c) Felicitex prior to
entering into any out-licensing transaction or Sale Transaction related (solely or inter alia) to Felicitex’
“DYRK1A/B” research program shall notify Selvita about such envisaged transaction and, promptly upon entering into such
transaction, shall disclose to Selvita any and all provisions of the underlying contractual agreement which are required or reasonably useful for Selvita to calculate
or audit its payment claims towards Felicitex under Article VII of this Agreement and

 

Exhibit D

 

    16

     

    

 

(d) Felicitex, in case of
both Internal Development and External Development, shall (except in the case of a Sale Transaction to a non-Affiliate of Felicitex
to which Selvita has previously consented (such consent not to be unreasonably withheld) or a merger, sale or acquisition in which
it is not the surviving entity) remain responsible towards Selvita for all Development and Commercialization activities outlined in
this Agreement as well as for all payment obligations pursuant to Article VII (in case of a Sale Transaction which involves an
assignment of this Agreement to a Third Party Partner in form of joint liability together with any assignee of Felicitex), and

 

(e) Felicitex, in case of
External Development following a Sale Transaction which involves an assignment of this Agreement to a Third Party Partner, shall
procure that such Third Party Partner submits itself to payment obligations applicable for External Development (pursuant to Section
7.3), as the Parties agree and acknowledge that Development and Commercialization of Optioned Compounds or Products that is
undertaken by a Third Party Partner constitutes External Development (not Internal Development, although such Third Party Partner
may become an assignee of Felicitex upon a Sale Transaction).

 

5.5 Reports. In addition
to its other reporting obligations under this Agreement, Felicitex (itself or through its Affiliate or Sublicensee or Third Party Partner,
as applicable) shall provide Selvita with regular periodic written reports summarizing in reasonable detail the plans, activities and
accomplishments of Felicitex (or its Affiliate or Sublicensee or Third Party Partner, as applicable) with respect to the further Research,
Development, Manufacturing and Commercialization of Optioned Compounds and Products. Such written reports shall be provided to Selvita
at least every Contract Quarter during the Term.

ARTICLE VII

 

COMMERCIAL TERMS

 

7.1 General Terms for Payments
to Selvita with Respect to Optioned Compounds and Products. In consideration of the rights granted to Felicitex hereunder, Felicitex
shall make the following payments to Selvita in accordance with the terms and conditions of this Article 7, whereas the payment obligations
outlined in Section 7.2 apply if and as long as Felicitex undertakes Internal Development and the payment obligations outlined in Section
7.3 apply if Felicitex undertakes External Development.

 

7.1.1 Initial Value
Share. With view to Selvita’s and Felicitex’s contributions to the Research and Development of the Optioned
Compounds the Parties agree and acknowledge that Selvita’s share in the value of the subject matter of this Agreement amounts
to  [**](“Initial Value Share”) [Note to Draft: specific initial value share percentage be completed in
final version pursuant to guidelines for calculation of the initial value share (V1 or V2) in Exhibit F, Part A of the RCO
Agreement.].

 

7.1.2 Step-Down Formula.
The Parties agree and acknowledge that Felicitex may undertake Development and Commercialization not only with regard to the Optioned
Compounds most advanced as of the Effective Date, but that Felicitex may proceed with the Development and Commercialization of any other
Optioned Compound for which a Patent with a Valid Claim Covering the Development, Manufacture or Commercialization of such given Optioned
Compound may be filed several months after the Effective Date. With a view to Optioned Compounds and only in case that Felicitex (or its
Affiliate or Sublicensee or Third Party Partner, as applicable) files the first Patent with a Valid Claim Covering the Development, Manufacture
or Commercialization of such Optioned Compounds or related Products after 31 January 2019, Selvita’s Initial Value Share shall be
decreased on basis of the following formula (“Decreased Value Share”), whereas the Parties agree that Felicitex (or
its Affiliate or Sublicensee or Third Party Partner, as applicable) shall file such first Patent for a given Optioned Compound no later
than upon the initiation of GLP Toxicology Studies with regard to such Optioned Compound:

 

Decreased Value Share =[**] -
([**])*(X-52)/24, where X is the number of months elapsed from 1 October
2014 until the month when the relevant application for the first Patent on such Optioned Compounds or related Products is filed.

 

Exhibit D

 

    18

     

    

 

Notwithstanding the aforesiad: If the application for the first
Patent on such Optioned Compounds or related Products is filed after 31 January 2021, the Decreased Value Share is zero percent
(0%).

 

For avoidance of doubt: The Step-Down Formula pursuant to this
Section 7.1.2 shall be applied only once to a given Optioned Compound.

 

7.1.3 Value Share Adjustment. Selvita’s Initial
Value Share or, if applicable, Decreased Value Share can be modified by up to [**] of its initial value (i.e. it can be [**] or [**]
of its initial value), if Felicitex’s costs for pre-clinical Development (IND enabling studies as reflected by invoices from CROs)
achieve or exceed [**] U.S. Dollars ([**]) or fall below thereof down to [**] U.S. Dollars (US$[**] In such case, Selvita’s Initial
Value Share, or if applicable, Decreased Value Share shall be recalculated on basis of the following formula (“Adjusted Value
Share”):

 

Adjusted Value Share (in
percent,%) = V - [V*[**]*(Y-2)/2)], where Y is the direct, evidenced CRO costs for IND-enabling studies in
Million U.S. Dollars (US$M) and V is the actual Initial Value Share or, if applicable, Decreased Value Share of Selvita as
defined in Section 7.1.1 or, if applicable, Section 7.1.2.

 

7.2 Payments During
Internal Development. If and to the extent that Felicitex undertakes the Development and Commercialization by way of Internal
Development, Felicitex shall make the following milestone and royalty payments to Selvita. The milestone and royalty payments
reflect the Initial Value Share and therefore are subject to adjustments in case that the Decreased Value Share or Adjusted Value
Share applies (any such adjustment to be undertaken pursuant to Section 7.2.1(c), Section 7.2.2(c) and Section 7.2.3(c) below).

 

7.2.1 Development Milestones for Internal
Development. Felicitex shall make the following non-refundable, non-creditable development milestone payments to Selvita. As
soon as Felicitex becomes aware that any of the milestone events outlined below has been achieved with respect to an Optioned
Compound or Product, Felicitex shall promptly inform Selvita about such occurrence.

(b) Royalty Term.
Royalties on Net Sales of a Product at the rates set forth in Section 7.2.3(a) shall become payable upon the First Commercial Sale of
a Product and shall continue to be payable, on a Product-by-Product and country-by-country basis, until expiration of the last Valid
Claim of a Selvita Patent or a Collaboration Patent Covering the Development, Manufacturing or Commercialization of the Product in the
relevant country. If a Patent that is filed after the Effective Date by Felicitex (or its Affiliate or Sublicensee or Third Party Partner,
as applicable) is not a Collaboration Patent, but another Patent Covering the Development, Manufacture or Commercialization of a given
Optioned Compound or Product, then in such case the royalty term shall continue until the expiration of the last Valid Claim of such
Patent and the Parties agree and acknowledge that in such case, upon expiration of the licensed Selvita Patents and Collaboration Patents,
the royalties shall remain payable for the Selvita Know-How and Collaboration Know-How licensed hereunder, but shall be reduced by [**]
to reflect the expiry of the licensed Selvita Patents and Collaboration Patents.

 

(c)
Adjustments.

 

(i) In case a Decreased Value Share is
applicable pursuant to Section 7.1.2, the royalty rate indicated in Section 7.2.3(a) shall be recalculated as follows:

 

Royalty rate multiplied by the Decreased Value Share (in
percent) and divided by the Initial Value Share (in percent)

 

(ii) In case an Adjusted Value Share is
applicable pursuant to Section 7.1.3, the royalty rate indicated in Section 7.2.3(a) shall be recalculated as follows:

 

Royalty rate multiplied by the Adjusted Value Share (in
percent) and divided by the Initial Value Share (in percent)

 

7.3 Payments
in Course of External Development.

 

7.3.1 Participation Income.
If and to the extent that Felicitex undertakes Development and Commercialization of Optioned Compounds or Products through External Development,
Felicitex shall pay to Selvita a participation payment on Participation Income in an amount equal to Selvita’s Initial Value Share
or, if applicable, Decreased Value Share or, if applicable, Adjusted Value Share in such Participation Income. Only in case of prior Internal
Development by Felicitex, under the assumption and condition that Felicitex undertakes investments into the Research and Development of
Optioned Compounds and Products from its own or any of its Affiliates’ own resources, the applicable Initial Value Share, Decreased
Value Share or Adjusted Value Share of Selvita for the Participation Income shall be reduced as described in Exhibit G (“Diluted
Value Share”) according the calculation scheme attached as Exhibit G.

 

Exhibit D

 

    22

     

    

 

“Participation Income” pursuant
to this Section includes all payments payable to Felicitex by such Sublicensee or Third Party Partner in connection with the rights granted
or assigned by Felicitex to such Sublicensee or Third Party Partner to Research, Develop, Manufacture and Commercialize the Optioned
Compounds or Products, including: (a) all upfront payments, (b) all milestone payments, (c) all royalties (or other recurrent payments
calculated on the basis of sales income), (d) all purchase prices and (e) all other revenues, receipts, monies and the fair market value
of other consideration directly or indirectly payable to Felicitex, whether by way of cash or credit or any benefit, advantage or concession.
Participation Income does not include or apply for (u) non-US taxes which are deducted or paid, but only to the extent that Felicitex
is not entitled to a refund of such taxes or duties, (v) sales, use, and/or value added taxes; (w) refunds or rebates; (x) payments for
Research, Development and/or Manufacturing services of Felicitex acting as a subcontractor or service provider (to the extent that the
compensation is for fair market value); (y) consideration received for the purchase of an equity interest in Felicitex (to the extent
that the compensation is for fair market value) and (z) reimbursement of patent costs of Felicitex. If Optioned Compounds or Products
are out-licensed or sold together with other compounds or products in the same transaction, then the Participation Income calculations
will be determined per Optioned Compound or Product at each component’s fair market value. An exemplary calculation of the participation
payment to Selvita is attached hereto as Exhibit H.

 

7.3.2 Further
Conditions for Participation Payments.

 

(a)
If the external Development and Commercialization by Felicitex pursuant to Section 7.3.1 commences after the achievement of one or more
milestones by Felicitex in course of an Internal Development, the payment obligations pursuant to Section 7.2 shall apply to such internally
achieved milestones and the payment obligations pursuant to Section 7.3 shall apply to all milestone events occurring after commencement
of the External Development;

 

(b) If Felicitex
undertakes the Development and Commercialization of Optioned Compounds and Products both through Internal Development and External
Development (for example in case of a partial out-licensing for certain indications or for certain territories only), Selvita shall
receive both (i) participation payments on Participation Income with view to the Optioned Compounds and Products which are developed
through External Development and (ii) the milestone and royalty payments pursuant to Section 7.2.1 to Section 7.2.3 with view to the
Optioned Compounds and Products which are developed through Internal Development.

 

(c) The Diluted Value
Share shall apply solely to the calculation of participation payments due by Felicitex to Selvita from External Development pursuant
to Section 7.3. For the avoidance of doubt, the Initial Value Share, Decreased Value Share or Adjusted Value Share, not the Diluted
Value Share, shall apply to other payments due by Felicitex to Selvita from Internal Development.

 

(d) Felicitex shall
promptly notify Selvita about (i) any invoice that Felicitex issues with regard to the Participation Income to its Sublicensee or
Third Party Partner and (ii) any receipt of Participation Income by Felicitex from its Sublicensee or Third Party Partner. Felicitex
participation payments to Selvita pursuant to this Section 7.3 are payable upon the earlier of (x) sixty (60) days after
Felicitex’s issuing an invoice with regard to the respective Participation Income to its Sublicensee or Third Party Partner or
(y) thirty (30) days after the date of the invoice from Selvita which Selvita may issue to Felicitex following Felicitex’
receipt of the Participation Income by Felicitex.

 

Exhibit D

 

    23

     

    

 

(e) In
the event that the Participation Income payable to Felicitex by a Sublicensee or Third Party Partner does not suffice to result in participation
payments to Selvita that are at least equal to the royalty and milestone payments that Selvita could expect from Felicitex in course
of Internal Development (taking into account the market value of the Optioned Compounds or Products as
well as actual sales of Products), then Selvita shall be entitled to receive minimum royalties from such Sublicensee or Third Party Partner.
Felicitex shall procure that any Sublicensee or Third Party Partner agrees to assume and comply with this payment obligation. If Felicitex’s
negotiations with a Sublicensee or Third Party Partner are hindered, endangered or impaired by this Section 7.3.2(e), Felicitex and Selvita
shall meet upon request of Felicitex and negotiate in good faith an alternative structure which meets both Parties’ economical
interests and is qualified to be more easily accepted by such Sublicensee or Third Party Partner. The minimum
royalties shall be calculated on basis of net sales of Products by such Sublicensee or other Third Party Partner (or any of their affiliates
or sublicensees, if applicable) to Third Party purchasers, it being understood that “net sales” in this context shall be calculated
basically in accordance with the Net Sales definition in this Agreement. The royalty rate for minimum royalties (“Minimum
Royalty Rate’) shall be calculated on basis of the basic minimum royalties table and Selvita’s “Minimum
Value Share” as follows:

 

(i) Basic
Minimum Royalties Table [Note to Draft: specific malty royalty to be completed in final version pursuant to the guidelines for calculation
of milestones in Exhibit F, Part D of the RCO Agreement.]

 

	Aggregate
    Calendar Year Net Sales of Products 

    in the Territory (in U.S. Dollars)	Royalty
    Rate
	US[**]	
	[**]	 
	Greater
    than US[**]	 

 

(ii) Calculation
Formula:

 

Minimum
Royalty Rate = Royalty rate from Basic Minimum Royalties Table*Vmin/Initial Value
Share, where Vmin (Minimum Value Share) is calculated as follows:

 

Minimum
Value Share (Vmin) = V - [V*[**]*(Y-2)/2], where Y is the direct evidenced CRO cost for IND-enabling
studies in Million U.S. Dollars (USSM) and V is either
the Initial Value Share or, if applicable. the Decreased Value Share of Selvita (whichever was applied for determination of the Basic
Milestone Royalties Table in Section 7.3.2(e)(i)).

 

(f) For the avoidance
of doubt: Any reference to Felicitex in this Section 7.3 shall apply accordingly to any of its Affiliates,
if the External Development is not initiated by Felicitex directly, but by any of its Affiliates.

 

Exhibit D

 

    24

     

    

 

7.4 Market Price. The
Parties unanimously declare that the payments hereunder correspond to the market price as set by the Parties on the basis of negotiations
conducted in good faith, each of the Parties acting independently. The market price set by both Parties provided for in this Agreement
corresponds to fair market prices based on similar transactions in the biotechnology industry. All rights and benefits inherent in (or
attributable to) the transaction under this agreement have been included in the Agreement. The execution of this Agreement was preceded
by the Parties elaborating a thorough analysis of the current situation in the biotech and pharmaceutical industry, with a special consideration
for the scientific characteristics of the target, its therapeutic potential, interest of the potential end customers and current stage
of Research.

 

7.5 Reporting
Obligations. Commencing with the First Commercial Sale of a Product and continuing until the expiration of Felicitex’s
payment obligations under this Article 7, Felicitex (itself or through its Affiliate or Sublicensee or Third Party Partner, as
applicable) shall provide to Selvita written reports outlining all conditions and circumstances which are required or reasonably
useful for Selvita to calculate or audit its payment claims towards Felicitex under this Agreement. Felicitex shall provide such
written reports in reasonable details within sixty (60) days after the end of each Calendar Quarter, in particular
outlining: (a) any milestones achieved by Felicitex, its Affiliates, its Sublicensees or its Third Party Partners, (b) Net Sales of
Products on a product-by-product and country-by-country basis in the Territory invoiced by Felicitex or its Affiliates during the
concerned Calendar Quarter, (c) royalties (or other recurrent payments on basis of sales of Products) invoiced by Felicitex from its
Sublicensees or its Third Party Partners during such Calendar Quarter and (d) upfront payments, milestone payments and any other
consideration invoiced by Felicitex from its Sublicensees or Third Party Partners in such Calendar Quarter. The information
contained in each report under this Section 7.5 shall be considered Confidential Information of Felicitex.

 

7.6 Accounting;
Audit Rights.

 

7.6.1 Record Keeping.
Felicitex agrees to keep, and to require its Affiliates and its Sublicensees and Third Party Partners to keep, full, clear and accurate
records of the underlying data relating to the reports and payments required by Article VII for a minimum period of five (5) years after
the relevant payment is owed pursuant to this Agreement.

 

7.6.2 Auditing.
Felicitex agrees to permit, and to require its Affiliates and, its Sublicensees and Third Party Partners to permit, upon not less
than thirty (30) days’ prior written notice, such books and records, as applicable, to be examined by an independent
accounting firm selected by Selvita and reasonably acceptable to the audited party, for the purpose of verifying reports provided by
Felicitex (or such other party) under this Agreement. Such audit shall not: (a) be performed more frequently than once in any twelve
(12) month period (unless a previous audit during such twelve (12) month period revealed a material discrepancy with respect to such
period), (b) be conducted for any Calendar Quarter more than three (3) years after the end of the Calendar Year of which such
Calendar Quarter is a part or (c) be repeated for any Calendar Quarter, and shall be conducted under appropriate confidentiality
provisions satisfactory to the audited party, for the sole purpose of verifying the accuracy and completeness of all financial,
accounting and numerical information and calculations provided under this Agreement. The independent accounting firm shall have the
right to make copies of relevant portions of the audited party’s books and records; provided that any such copies shall
be the Confidential Information of the audited party, shall be protected by appropriate confidentiality obligations and shall not be
shared with Selvita or any other Person. The independent accounting firm will prepare and provide to Felicitex and Selvita a written
report stating only whether the reports submitted and amounts paid hereunder were correct or incorrect, and the amounts of any
discrepancies. Within thirty (30) days following receipt of such report, any discrepancy amounts (together with accrued interest
calculated in accordance with Section 7.8) shall, in case of underpayments, be paid by the owing Party to the other Party, or, in
case of overpayments, shall be reimbursed by the owing Party to the other Party.

 

Exhibit D

 

    25

     

    

 

7.6.3 Costs of
Examination. Such examination is to be made at the expense of Selvita, except if the results of the audit reveal an underpayment
of royalties, milestone payments or other amounts to Selvita by Felicitex of [**] or more in any calendar year, in which case the
audit fees for such examination shall be paid by Felicitex.

 

7.7 Payments; Conversion.
All payments due under this Agreement shall be made in U.S. Dollars by electronic funds transfer to a bank account designated in writing
in the invoice of the receiving Party. If converted into Euro, the conversion shall be based on the exchange rate applicable at close
of business Boston time at the last Business Day of the preceding Calendar Quarter. Unless otherwise specified in this Agreement or otherwise
agreed by the Parties, each payment hereunder shall be due thirty (30) days after the corresponding invoice date.

 

7.8 Late Payments.
Any amount owed by Felicitex to Selvita under this Agreement that is not paid on or before the date such payment is due shall bear interest
at a rate per annum equal to the lesser of: (a) the prime or equivalent rate per annum quoted by The Wall Street Journal, Eastern Edition
on the first Business Day after such payment is due, plus one hundred basis points and (b) the highest rate permitted by applicable Law,
in either case calculated on the number of days such payments are paid after such payments are due and compounded monthly.

 

7.9 Withholding or Other
Taxes. The Parties agree to cooperate in good faith to provide one another with such documents and certifications as are reasonably
necessary to enable Felicitex and Selvita to minimize or recover any tax payment. Felicitex may withhold taxes in the event that revenue
authorities within the United States require the withholding of taxes on amounts to be paid hereunder to Selvita under applicable tax
treaties between Poland and the United States, and in any such event Felicitex shall deduct such taxes from such payment and such taxes
shall be paid by Felicitex to the proper taxing authority of the United States on behalf of Selvita (evidence of which payment to such
taxing authority shall be provided promptly by Felicitex to Selvita hereunder). In case that Felicitex, any of its Affiliates, its Sublicensees
or any Third Party Partner undertakes a payment to Selvita from any country outside the United States and such payment triggers other
or additional taxes (including VAT or withholding taxes) than such a payment made from within the United States would have triggered,
then such additional taxes shall be paid to the proper taxing authority outside of the United States by the liable party (whereas, in
case of Selvita, Felicitex, its Affiliate, its Sublicensee or Third Party Partner shall make the tax payment on behalf of Selvita (evidence
of which payment to such taxing authority shall be provided promptly to Selvita)), provided, however, that in any such event Felicitex,
its Affiliates, its Sublicensees or Third Party Partner shall gross-up the relevant payment due to Selvita, so that Selvita receives the
same net amount it would have received had the payment been made from the United States (taking
into consideration applicable tax treaties between the United States and Poland); provided, further, however, that no such gross-up
or grossed-up payment shall be due to Selvita if Felicitex’ headquarters for tax domicile purposes is within the United States.

Party, and each Party hereby waives any right it may have under Laws to require any such consent or accounting.

 

9.2 Prosecution and Maintenance of Patents.

 

9.2.1 Selvita Patents.
Selvita shall have the sole right (but not the obligation) to Prosecute and Maintain the Selvita Patents; provided however that if Selvita

and thereafter Felicitex shall have the right (but not the obligation) to Prosecute and Maintain the Selvita Patents. In the event that
Felicitex elects to Prosecute and Maintain the Selvita Patents, then all cost and expenses associated therewith, on a country by country
basis, shall be paid by Felicitex and offset against any royalties payable by Felicitex to Selvita for sales in such relevant country.
Unless such consultation is prohibited by a Third Party agreement or would otherwise compromise or jeopardize patent strategy on another
Selvita patent or patent application unrelated to this Agreement, Selvita shall provide Felicitex with a reasonable opportunity to substantively
comment on Prosecution and Maintenance of any Selvita Patent which Covers or claims Optioned Compounds prior
to taking material actions (including the filing of initial applications), and will in good faith consider any actions recommended by
Felicitex regarding such Selvita Patents. Felicitex shall have the right to review and make comments on and recommendations in relation
to the Prosecution and Maintenance of such Patents; provided that Felicitex does so promptly and consistent with any applicable

(90) days before any deadline applicable to the Prosecution or Maintenance of such Collaboration Patent, as the case may be, or any
other date by which an action must be taken to establish or preserve such Collaboration Patent in such country or possession. In
such case, at Selvita’s request, Selvita shall have the right to pursue the filing or support the continued Prosecution or
Maintenance of such Collaboration Patent in its own name, through patent counsel of Selvita’s choice and at Selvita’s
cost and expense, and in such case the ownership in such Collaboration Patent shall then be assigned to Selvita. Any Collaboration
Patent assumed by Selvita in accordance with the foregoing shall, prospectively from the date of such assumption, be excluded from
the Collaboration Patent as defined under this Agreement. Under Section 9.2.3(b), Selvita shall be likewise entitled to Prosecute
and Maintain at its own expense (including, where possible, in form of a separate Patent, such as a divisional

Parties (collectively, “Losses”), arising out of or resulting from any and all Third Party suits, claims, actions,
proceedings or demands (“Claims”) based upon:

 

(a) the negligence,

their respective directors, officers, employees and agents, in connection with the Indemnifying Party’s performance of its
obligations or exercise of its rights under this Agreement;

 

Exhibit D

 

    35

     

    

 

(b) any breach of any representation or warranty or covenant made by the Indemnifying Party under Article XI or any other provision under
this Agreement;

 

(c) the Research,
Development, Manufacturing and Commercialization of Optioned Compounds that is actually conducted by or on behalf of the
Indemnifying Party, its Affiliates or Sublicensees the handling and storage by or on behalf of the Indemnifying Party, its
Affiliates or Sublicensees of any chemical agents or other compounds for the purpose of conducting Research or Development or
Commercialization by or on behalf of the Indemnifying Party, its Affiliates or Sublicensees or Third Party Partners, including any
product liability, personal injury, property damage or other damage; or

 

(d) any gross negligence,
recklessness, wrongful intentional act or omission, failure to comply with any Law, breach of any agreement with a Third Party, or
infringement of Patent or other intellectual property rights of any Third Party by the Indemnifying Party, its Affiliates or
Sublicensees with respect to the Research, Development, Manufacturing or Commercialization of any Optioned Compound or Product
anywhere in the world prior to the Effective Date or under this Agreement;

 

in each case, provided that, such indemnity
shall not apply to the extent that the Indemnified Party itself has an indemnification obligation pursuant to this Section for such Loss,
in which event each Party shall indemnify the other to the extent of their respective liability for such Loss.

 

12.2 Indemnification regarding
SEL141 Grant. In case of a breach of Felicitex’s obligations under Section 5.3.1 (Implementation), Section 5.3.2 (Implementation
Statement) or Section 5.3.3 (No Direct Disposal), Felicitex shall indemnify, defend and hold harmless Selvita and its Affiliates from
and against any and all liability, damage, loss, cost or expense (including reasonable attorneys’ fees) (“SEL141 Loss”)
arising out of or resulting from a premature termination of the SEL141 Grant by the Polish Agency for Enterprise Development or by any
other competent governmental authority, to the extent such termination and SEL141 Loss is caused due to a breach by Felicitex of its obligations
under Sections 5.3.1 to 5.3.3. In the event that Selvita receives notice of any breach, threatened breach or violation of SEL141 Grant
by Felicitex, its Affiliates or Sublicensees,, then Selvita shall immediately notify Felicitex and provide Felicitex with the information

12.3 Procedure.

 

12.3.1 Notice of Claim.
An Indemnified Party seeking indemnification under this Article 12 shall give prompt written notification to the Indemnifying Party of
the Third Party Claim for which indemnification may be sought (it being understood and agreed, however, that the failure by an Indemnified
Party to give notice of a Third Party Claim as provided in this Section shall not relieve the Indemnifying Party of its indemnification
obligation under this Agreement except and only to the extent that such
Indemnifying Party is actually prejudiced as a result of such failure to give notice).

 

Exhibit D

 

    36

     

    

  

12.3.2 Assumption of Defense;
Participation. Within ninety (90) days after delivery of such notification, the Indemnifying Party may, upon written notice thereof
to the Indemnified Party, assume control of the defense of such Third Party Claim with counsel reasonably satisfactory to the Indemnified
Party. If the Indemnifying Party does not assume control of such defense, the Indemnified Party shall control such defense and, without
limiting the Indemnifying Party’s indemnification obligations, the Indemnifying Party shall reimburse the Indemnified Party for
all costs and expenses, including reasonable attorneys’ fees and disbursements, incurred by the Indemnified Party in defending itself
within sixty (60) days after receipt of any invoice therefore from the Indemnified Party. The Party not controlling such defense may participate
therein at its own expense; provided, however, that, if the Indemnifying Party assumes control of such defense and
the Indemnified Party in good faith concludes, based on written advice from outside counsel, that the Indemnifying Party and the Indemnified
Party have conflicting interests with respect to such Third Party Claim sufficiently adverse to make unadvisable the representation by
the same counsel of both Parties under Law, ethical rules or equitable principles, the Indemnifying Party shall be responsible for the
reasonable fees and expenses of a single counsel to the Indemnified Party in connection therewith. The Party controlling such defense
shall keep the other Party advised of the status of such Third Party Claim and the defense thereof and shall consider recommendations
made by the other Party with respect thereto.

 

12.3.3 Settlements. The
Indemnifying Party shall not agree to any settlement of such Third Party Claim or consent to any judgment in respect thereof that does
not include a complete and unconditional release of the Indemnified Party from all liability with respect thereto, that imposes any liability
or obligation on the Indemnified Party or that acknowledges fault by the Indemnified Party, without the prior written consent of the Indemnified
Party.

ARTICLE XIV

MISCELLANEOUS

 

14.1 Dispute Resolution.
If a dispute between the Parties arises under this Agreement, either Party shall have the right to refer such dispute in writing to the
respective Executive Officers, and such Executive Officers shall attempt in good faith to resolve such dispute. If the Executive Officers
are unable to resolve a given dispute pursuant to this Section within sixty (60) days after referring such dispute to the Executive Officers,
or sooner if required by the particular circumstances, either Party may elect to have the given dispute settled by binding arbitration
pursuant to Section 14.2.

 

14.2 Arbitration.

 

14.2.1 Arbitration Request.
If a Party intends to begin an arbitration to resolve a dispute arising under this Agreement, such Party shall, within thirty (3) days
following the expiration of the sixty (60) day mediation period referred to in Section 14.1 of this Agreement, provide written notice
(the “Arbitration Request”) to the other Party of such intention and a statement of the issues for resolution. From
the date of the Arbitration Request and until such time as the dispute has become finally settled, the running of the time periods as
to which the other Party must cure a breach of this Agreement shall be suspended as to any breach that is the subject matter of the dispute,
however, this Agreement shall remain in full force and effect and the Parties shall continue their obligations hereunder during the pendency
of the arbitration(s). Within thirty (30) days after the receipt of the Arbitration Request, the other Party may, by written notice, add
additional issues for resolution in a statement of counter-issues. Any arbitration pursuant to this Section will be held in accordance
with the International Arbitration Rules of the International Centre for Dispute Resolution (“ICRD”), the international division
of the American Arbitration Association, whereas, to the extent legally permissible, the procedure agreed in Section 14.2.2 shall be applied.

 

14.2.2 Arbitration Procedure.
The arbitration shall be held in Boston, Massachusetts, United States unless another location is mutually agreed by the Parties. The arbitration
shall be conducted by a single arbitrator knowledgeable in the subject matter at issue in the dispute and acceptable to both Parties;
provided that, the Parties may by mutual agreement elect to have the arbitration conducted by a panel of three (3) arbitrators.
If the Parties fail to agree on a mutually acceptable arbitrator within thirty (30) days after the Arbitration Request, then the arbitrator
shall be selected by the ICRD. The arbitrator may proceed to an award, notwithstanding the failure of either Party to participate in the
proceedings. The arbitrator shall, within thirty (30) days after the conclusion of the arbitration hearing, issue a written award and
statement of decision describing the essential findings and conclusions on which the award is based, including the calculation of any
damages awarded. The arbitrator shall be limited in the scope of his or her authority to resolving only the specific matter which the
Parties have referred to arbitration for resolution and shall not have authority to render any decision or award on any other issues.
The arbitrator shall be authorized to award compensatory damages, but shall not be authorized to award punitive, special, consequential,
or any other similar form of damages, except as provided for in Section 12.5, or to reform, modify or materially change this Agreement.
The arbitrator also shall be authorized to grant any temporary, preliminary or permanent equitable remedy or relief the arbitrator deems
just and equitable and within the scope of this Agreement, including an injunction or
order for specific performance. The Parties hereby expressly agree to waive the right to appeal from the decisions of the arbitrator,
and there shall be no appeal to any court or other authority (government or private) from the decision of the arbitrator. Judgment on
the award rendered by the arbitrator may be enforced in any court having competent jurisdiction thereof.

this Agreement, force majeure is defined as causes beyond the control of the Party, including acts of God; material changes in Law; war;
civil commotion; destruction of production facilities or materials by fire, flood, earthquake, explosion or storm; labor disturbances;
epidemic; and failure of public utilities or common carriers. In such event Selvita or Felicitex, as the case may be, shall immediately
notify the other Party of such inability and of the period for which such inability is expected to continue. The Party giving such notice
shall thereupon be excused from such of its obligations under this Agreement as it is thereby disabled from performing for so long as
it is so disabled for up to a maximum of ninety (90) days, after which time Selvita and Felicitex shall promptly meet to discuss in good
faith how to best proceed in a manner that maintains and abides by the Agreement. To the extent possible, each Party shall use reasonable
efforts to minimize the duration of any force majeure.

the validity of any other material provision(s) of this Agreement (“Severed Clause”), all other provisions hereof shall
remain in full force and effect in such jurisdiction except for such Severed Clause, and such invalidity, illegality or unenforceability
shall not affect the validity, legality or enforceability of such provision in any other jurisdiction. The Parties shall consult and use
good faith efforts to agree upon a valid and enforceable provision which shall be a reasonable substitute for such Severed Clause in light
of the intent of this Agreement.

Procedure for Calculating Structural Similarity

 

Two compounds will be considered as derivatives
of each other if their Stated Similarity Coefficient will be >=0.85.

 

For avoidance of doubt, Stated Similarity Coefficient will
be calculated on neutral compounds except in the case of “onium” compounds, formed by substituents other than hydrogen (example:
benzalkonium chloride).

 

The algorithm to calculate the Stated Similarity Coefficients
is presented below:

 

Proposed is to define structural similarity basing
on the MACCS fingerprint definition used in a public domain chemoinformatics toolkit “Open Babel” (O’Boyle et al.,
2011). Open Babel is an Open Source chemistry toolbox, broadly accepted and used in chemoinformatics. The examples presented were generated
using the Open Babel version 2.3.2 (from 17-02-2013), downloaded from their website: http://sourceforge.net/projects/openbabel/ MACCS
key fingerprint definition contains a list of SMART queries, and is accessible as a text file on the openbabel installation directory.
On Linux it is: /usr/local/share/openbabel/2.3.2/MACCS.txt.

 

The procedure for the structural similarity is as follow:

 

1.
Generate an SDF formatted file with the query compound

 

2.
Generate an SDF formatted file with the compounds from the compared library

 

3.
Run the openbabel fingerprint similarity procedure, with Tanimoto similarity coefficient, using the command:

 

obabel query.sdf library.sdf –ofpt -xfMACCS

where: query.sdf and library.sdf are the files created
in points 1 and 2.

 

4. Analyze the output of the program (see example below).

 

Example: Calculating of similarity of Gefitinib (Iressa) to
20 selected, approved small molecule kinase inhibitors (taken from Figure 1 from the KLIFS article (van Linden, Kooistra, Leurs, de Esch 
& de Graaf, 2013)

Definitions:

 

“Chemical fingerprint” means
a string of binary values (0 or 1) used to characterize a molecule. In the presented definition, MACCS structural fingerprint was proposed
to describe the compared compound. The MACCS definition of structural keys is frequently used in chemoinformatics, because it allows assigning
unambiguously a binary string to the given structure. In the case of other, hashed fingerprints, the particular binary representation
may depend on the algorithm used; therefore, the particular result of comparison may depend on the software used.

 

In the presented examples, MACCS fingerprints
are calculated using a publicly accessible program Open Babel. MACCS fingerprint is created using structural key descriptors in which
each bit is associated with a SMARTS pattern.

 

A structural key is a fixed-length bitstring in
which each bit is associated with a specific molecular pattern. When a structural key is generated for a molecule, the bitstring encodes
whether or not these specific molecular patterns are present or absent in the molecule. The performance of such keys depends on the choice
of the fragments used for constructing the keys and the probability of their presence in the searched molecule databases.

 

“SMARTS” means a language that
allows specifying substructures by providing a number of primitive symbols describing atomic and bond properties. Atom and bond primitive
specifications may be combined to form expressions by using logical operators. For more information go to: http://www.daylight.com/dayhtml/doc/theory/theory.smarts.html.

 

“Tanimoto similarity coefficient” means
the most commonly used similarity coefficient in chemical informatics. It is often applied to comparison of binary strings, and may be
calculated using the equation:

 

	SIM Tanimoto =	c
	a+b-c

 

where:

 

a –the number of
“on” features (bits) in structure A)

b – the number of
“on” features (bits) in structure B

c – the number of “on” features (bits) common
to both fingerprints A and B

 

The range of Tanimoto coefficient is from 0 to 1, with larger values
for more similar compounds.

Brown and Martin (Brown & Martin, 1997) found
that 2D descriptors (in combination with hierarchical clustering) are best at separating actives from inactives, given a particular target.
Structural keys, hashed fingerprints and different 3D descriptors were compared and authors concluded that the MACCS structural key descriptor
implicitly contains a great deal of information relevant to each type of interaction.

“Stated Tanimoto similarity coefficient”
– means Tanimoto coefficient, calculated using MACCS fingerprint representation, is more than 0.85.

Calculation Scheme for the Diluted Value
Share

 

Depending on the stage of Development at which
Felicitex undertakes External Development, Selvita’s Initial Value Share, Decreased Value Share or Adjusted Value Share, whichever
is applicable, shall be diluted pursuant to the following table:

 

	Project progress upon External 

Development	 	Felicitex share after dilution

of Selvita’s applicable value shares	 	Selvita’s dilution

factor (Vd)
	 	 	 	 	 
	IND-ready candidate	 	[**]	 	[**]
	 	 	 	 	 
	Drug after successful Phase I	 	[**]	 	[**]
	 	 	 	 	 
	Drug after successful Phase II	 	[**]	 	[**]
	 	 	 	 	 
	Drug after successful Phase III	 	[**]	 	[**]
	 	 	 	 	 
	Approved drug	 	[**]	 	[**]

 

Therefore, the Diluted Value Share shall be determined pursuant to
the following table:

 

	Project progress upon External Development	 	Diluted Value Share (Vf)
	 	 	 
	IND-ready candidate	 	Initial Value Share, Decreased Value Share or Adjusted Value
Share (whichever is applicable) (Va)
	Drug after successful Phase I	 	Va*[**]
	Drug after successful Phase II	 	Va*[**]
	Drug after successful Phase III	 	Va*[**]
	Approved drug	 	Va*[**]

 

Accordingly, the participation payments on Participation
Income payable by Felicitex to Selvita shall be calculated on basis of the calculation formula below (which takes into account the dilution
pursuant to the table above):

 

Participation Payment = Vf*(Participation Income), where Vf=Va*(Vd/[**]/
%).
