--------------------------------------------------------------------------------

 

2.

Definition.  Section 1.26 is hereby deleted in its entirety and replaced with
the following:

1.26 “Collaboration Target” means the Initial Collaboration Targets set forth on
Exhibit F and any Additional Target, Extension Target, or Substitute Target that
is selected in accordance with Section 3.3 of this Agreement.  

 

3.

Definition.  Section 1.103 is hereby deleted in its entirety and replaced with
the following:

1.103“Product Specific Patent” means any Patent (including all claims and the
entire scope of claims therein) Controlled as of the Effective Date or
thereafter during the Term by CytomX (or any CytomX Affiliate) (including
CytomX’s interest in any Joint Patents) that specifically Covers the
composition, formulation, or method of use of any Compound and/or Product, but
does not cover any other subject matter, such as Probodies against targets other
than Collaboration Targets.  Notwithstanding the foregoing, [***] As of the
Execution Date, the Product Specific Patents consist of the Patents listed in
Exhibit C.

 

4.

Definition.  Section 1.122 is hereby deleted in its entirety and replaced with
the following:

1.122“Target” means: (i) a protein and any fragments thereof (that preserve the
utility of the full length protein as a target), encoded by a gene sequence or
identified in GenBank by an accession number, including any isoforms, mutants,
and polymorphisms thereof,  or (ii) a distinct non-protein biomolecule (e.g., a
lipid-bound carbohydrate), as such biomolecule is identified in GenBank by an
accession number or similar structural information that identifies such
biomolecule, or (iii) upon mutual agreement of the Parties (not to be
unreasonably withheld), after good faith discussion at the JRC, any other
distinct biomolecule (e.g., a protein-bound carbohydrate), in each case that is
capable of being bound by an Antibody.  For clarity, a non-fucosylated version
of any protein, fragment, or biomolecule described in (i), (ii) or (iii) above
shall constitute the same “Target” as any corresponding protein, fragment, or
biomolecule described in (i), (ii) or (iii) above (regardless of whether a
separate and distinct Probody is generated or utilized with respect to such
non-fucosylated version of any protein, fragment, or biomolecule.

 

5.

Research Term.  Section 3.2(a) is hereby deleted in its entirety and replaced
with the following:

The Preclinical Development Program with respect to each Initial Collaboration
Target and Additional Target will be carried out during the two (2) year period

described in Section 3.3(d) below.

(iii)Additional Target Option. BMS shall have the right to add up to two (2)
additional Targets to the collaboration (each such target, an “Additional
Target”), subject to payment of the Additional Target Payment, and further
subject to the Excluded Target Process set forth in Section 3.3(c) (the
“Additional Target Option”).  Any such Additional Target must be selected by BMS
prior to the fifth (5th) anniversary of the Effective Date by notice to CytomX.
For clarity, BMS may designate an Additional Target that is directed to any
indication within the field of oncology (including immuno-oncology), including a
Target intended for a Probody-drug conjugate program.

 

[***] Certain information in this document has been omitted and filed separately
with the Securities and Exchange Commission. Confidential treatment has been
requested with respect to the omitted portions.

--------------------------------------------------------------------------------

(iv)Extension Targets.  After the Amendment Effective Date, BMS shall have the
right to add up to eight (8) additional Targets to the collaboration (each such
target, an “Extension Target”).  Any such Extension Target must be selected by
BMS prior to the [***] anniversary of the Amendment Effective Date by notice to
CytomX.  Up to six (6) of the Extension Targets may be in the field of oncology
(including immuno-oncology). BMS shall have the right to request CytomX to
generate Probodies which can be used and further developed as: (A) Probodies or
Probody drug conjugates and/or (B) Probody-containing bi-specifics, including
T-cell engaging bi-specifics (with each of (A) and (B) being referred hereafter
as a “Modality”) for the Expansion Targets.

(v)[***] Target.  In addition to the Additional Targets and Extension Targets,
[***] is hereby designated as a Collaboration Target, solely for the purpose of
developing T-cell engaging bispecifics to be used solely in combination with a
Probody targeting an Extension Target [***].  

(vi)Substitute Targets. BMS shall have the right to substitute and replace (i)
each Initial Collaboration Target and up to [***] of the Extension Targets
[***], in accordance with the criteria set forth in clause (A) of this Section,
and (ii) up to [***] of the Extension Targets in accordance with clause (B) of
this Section, with a new Target (such new target, a “Substitute Target”),
subject to the Excluded Target Process set forth in Section 3.3(c).  Any such
replacement of an Initial Collaboration Target must occur prior to the
commencement of a Clinical Trial of a Compound relating to such Initial
Collaboration Target and in no case later than three (3) years after the
Effective Date. [***]  Any such replacement also shall be based on
technical/scientific information relating to such Initial Collaboration Target
[***] (or a Compound relating to such Initial Collaboration Target [***], based
upon which BMS reasonably determines that identification of a Compound(s)
directed to such Initial Collaboration Target [***] that would be suitable for
clinical development will not be feasible, [***]. In the case where BMS desires
to replace an Initial Collaboration Target or Extension Target with a proposed
Substitute Target, BMS shall inform CytomX, through the JRC, of BMS’ basis (and
providing technical/scientific supporting information) for wanting to replace
such Initial Collaboration Target or Extension Target. For clarity, BMS may
designate a Substitute Target that is directed to any indication within the
field of oncology (including immuno-oncology), including a Target intended for a
Probody-drug conjugate program, provided that such selection shall not be deemed
to expand the limits on Extension Targets set forth in Section 3.3(a)(c)(iv).

(vii)Update to Preclinical Plan; Reversion of Rights.  In the case of any such
designation of an Additional Target or Extension Target or a replacement of an
Initial Collaboration Target or Extension Target with a Substitute Target, in
advance of work being initiated by the Parties with respect to such Additional
Target, Extension Target or Substitute Target, the JRC shall update the
Preclinical Plan and Budget to include work on such Additional Target, Extension

 

[***] Certain information in this document has been omitted and filed separately
with the Securities and Exchange Commission. Confidential treatment has been
requested with respect to the omitted portions.

--------------------------------------------------------------------------------

Target or Substitute Target, with the Preclinical Plan expected to be similar in
scope and FTE effort as specified for each of the initial projects under the
initial Preclinical Plan, it being understood that the Preclinical Development
Program may be extended with respect to the Substitute Target, Extension Target
or Additional Target.  Each Party shall use reasonable best efforts to ensure
that the JRC meets as promptly as reasonably practicable (and no later than
within 45 Business Days) upon designation of an Additional Target, Extension
Target or a replacement of an Initial Collaboration Target or Extension Target
with a Substitute Target in order to develop and approve an updated Preclinical
Plan and Budget with respect to such Additional Target, Extension Target or
Substitute Target. Upon replacement of an Initial Collaboration Target or
Extension Target with a Substitute Target, following the procedure set forth
above, the previously designated Initial Collaboration Target or Extension
Target shall no longer be considered a Collaboration Target, and all rights to
the CytomX Technology related to such Initial Collaboration Target shall revert
to CytomX in accordance with Section 13.6.  

(d)Excluded Target Process.  The following procedure shall be followed for the
selection of an Additional Target or Extension Target or the replacement of an
Initial Collaboration Target or an Extension Target with a Substitute
Target.  Upon notice by BMS to CytomX of its desire to designate a Target as an
Additional Target, Extension Target or a Substitute Target, CytomX shall provide
an independent reviewer (mutually agreed to by BMS and CytomX) (the “Target
Reviewer”) with a list of all targets where CytomX has: (1) licensed exclusive
rights to a third party with respect to such target, or is otherwise
contractually restricted from including such target, (2) entered into (and has
maintained ongoing) discussions with a third party with respect to a license or
collaboration regarding potential products intended for use against such target,
with such discussions being evidenced by written correspondence relating to
proposed terms (“Ongoing Bona Fide Discussions”), (3) an active bona fide
internal research or development program, with respect to the research,
development and commercialization of Probodies directed towards such target
under which program CytomX has identified a functional Antibody directed toward
such target (as part of development of Probodies directed to such target), or
(4) the three (3) targets listed on Exhibit G hereto (“Reserved Targets”) for
the period of twelve (12) months after the Effective Date (and thereafter only
if included under (a)-(c) above),  (any such target, an “Excluded Target”, and
such list, the “Excluded Target List”), and CytomX shall notify BMS that the
Excluded Target List has been provided to the Target Reviewer.  Upon receipt of
such notice BMS shall provide to the Target Reviewer the new Target that BMS
proposes to become an Additional Target, Extension Target or a Substitute
Target, including the GenBank accession number (or other identifying
information) for such Target.  The Target Reviewer would notify BMS, within five
(5) business days if the Target proposed by BMS as an Additional Target,
Extension Target or as a Substitute Target is an Excluded Target (but not the
reason such Target is an Excluded Target).  In each circumstance where BMS
notifies CytomX of its desire to designate a Target as the subject of a
Substitute Target, Extension Target or Additional Target,

 

[***] Certain information in this document has been omitted and filed separately
with the Securities and Exchange Commission. Confidential treatment has been
requested with respect to the omitted portions.

--------------------------------------------------------------------------------

CytomX shall provide the Target Reviewer with an updated Excluded Target List
prior to BMS proposing such new Target to the Target Reviewer.  Accordingly,
CytomX shall inform the Target Reviewer (A) of any new targets that have become
subject to third party obligations, terms discussions or part of an active bona
fide internal development program of CytomX, as provided above; (B) the
expiration of the twelve month period referenced in clause (d) above (or
unilateral termination by CytomX) of such period with respect to any Reserved
Target) and any Reserved Targets that are no longer reserved by virtue of such
clause (4); and (C) any new targets that have become available due to the
termination of a collaboration (or Ongoing Bona Fide Discussions with a third
party) or termination of any internal development program of CytomX.  Any
proposed Target that is not an Excluded Target (under the procedure set forth
above) would be deemed selected by BMS as the Additional Target Extension
Target, or Substitute Target.  [***]  

 

7.

FTE Funding.  Sections 3.4(a) and 3.4(b) are hereby deleted in their entirety
and replaced with the following.

(a)Funded CytomX FTEs; FTE Rate.  Subject to Section 3.4(b), BMS will fund at
the FTE Rate, and CytomX will provide the number of CytomX FTEs per Research
Year during the Research Term to perform activities in support of the
Preclinical Development Program, in accordance with the then-current Preclinical
Plan, and in accordance with this Section 3.4.  Throughout the Research Term,
CytomX shall assign no less than the number of qualified CytomX FTEs in
accordance with this Section 3.4 to perform the work set forth in the
then‑applicable Preclinical Plan, which currently contemplates [***] FTEs in the
first year of the Research Term and [***] FTEs in the second year of the
Research Term.  [***]  The professional skills and expertise levels of such FTEs
shall be appropriate to the scientific objectives of the Preclinical Development
Program.  The FTE Rate during the first five years of the Research Term shall be
[***] per FTE per year (subject to adjustment pursuant to Section 1.62).  For
the avoidance of doubt, nothing in this Agreement herein shall be considered to
establish an employment relationship between BMS and the CytomX FTEs funded by
BMS pursuant to this Agreement.

(b)Changes to the Number of Funded FTEs.  If the activities contemplated by the
Preclinical Plan at any time during the Research Term do not justify the number
of CytomX FTEs allocated to the Preclinical Development Program, the Parties
will work in good faith to mutually agree to modify the scope of the Preclinical
Plan or adjust the number of BMS‑funded CytomX FTEs.  The number of CytomX FTEs
to be funded by BMS and provided by CytomX in support of the conduct of the
Preclinical Development Program may be increased or decreased by the JRC in
accordance with changes in the Preclinical Development Program and Preclinical
Plan and shall be specified for each calendar quarter in the Budget as set forth
in Section 3.3(a), provided that the number of CytomX FTEs to be provided by
CytomX would not be decreased below [***] FTEs or increased to exceed

 

[***] Certain information in this document has been omitted and filed separately
with the Securities and Exchange Commission. Confidential treatment has been
requested with respect to the omitted portions.

--------------------------------------------------------------------------------

[***] FTEs during the Research Term without CytomX’ written consent.  Any
changes to the Preclinical Plan and assignment and allocation of work to be
performed by the BMS‑funded CytomX FTEs shall require the approval of the JRC,
provided that if the JRC is unable to reach consensus, BMS shall have final
decision making authority, subject to the following: (i) BMS’ decision making
shall be subject to Section 2.1(d), (ii) the number of CytomX FTEs to be
provided by CytomX shall not be increased to exceed [***] FTEs without CytomX’
prior written consent.  

 

8.

Development.  Section 4.1 is hereby amended by adding new subsections (c) and
(d):

(c)Meetings.  From the date [***] the Parties agree to meet semi-annually in
person or by video conference (provided at least one meeting per year is held in
person), [***]. During these Development meetings, the Parties will exchange
preclinical and clinical development information, such as pre-clinical,
manufacturing, toxicological, clinical trial design information, and development
program timelines, relating to the Product [***].

(d)Pharmacovigilance Agreement. Within [***], the Parties, (under the guidance
of their Pharmacovigilance Departments, or equivalent thereof) shall define and
finalize the responsibilities  the Parties shall employ to protect patients and
promote their well-being in connection with the use of the Compounds and or
Products. [***] Such guidelines and procedures shall be in accordance with, and
enable the Parties and their Affiliates to fulfill, local and international
regulatory reporting obligations to Governmental Authorities. Furthermore, such
agreed procedures shall be consistent with relevant International Council for
Harmonization (ICH) guidelines, except where said guidelines may conflict with
existing local regulatory safety reporting requirements, in which case local
reporting requirements shall prevail. [***] In the event that this Agreement is
terminated, the Parties agree to implement the necessary procedures and
practices to ensure that any outstanding pharmacovigilance reporting obligations
are fulfilled.

 

9.

License to BMS.  Section 7.1(a) is hereby deleted in its entirety and replaced
with the following:

(a)Subject to the terms and conditions of this Agreement, CytomX hereby grants
to BMS an exclusive (even as to CytomX) license, with the right to grant
sublicenses as provided in Section 7.2, under the Product Specific Patents to

Territory (including, for clarity, the Masks and Antibodies set forth on
Schedule 1.30, or any Compounds comprising such materials); provided that BMS
covenants to CytomX that BMS, and its Affiliates and Sublicensees, shall only
practice under such exclusive license in the Field in the Territory; and further
provided, [***].  

 

[***] Certain information in this document has been omitted and filed separately
with the Securities and Exchange Commission. Confidential treatment has been
requested with respect to the omitted portions.

--------------------------------------------------------------------------------

 

10.

Licenses to CytomX.  Section 7.3 is hereby amended by adding new subsection (d):

(d)Grant to CytomX Technology Improvements.  Subject to the terms and conditions
of this Agreement, BMS hereby grants to CytomX a co-exclusive, sublicensable,
royalty-free license under the Sole Inventions owned by BMS to the extent such
Sole Inventions owned by BMS are specifically related to the CytomX Technology.
As used in this Section 7.3(d), the term “co-exclusive” means that BMS may only
license such Sole Inventions owned by BMS that are specifically related to the
CytomX Technology to a Third Party in connection with a grant of rights to a
Product developed under this Agreement.

 

11.

Upfront Payment.  Section 8.1 is hereby amended by adding new subsection (c):

(b)The milestone payments set forth above shall be payable by BMS to CytomX for
a given Collaboration Target upon the first achievement of the milestone event
for the first Compound or Product for such Collaboration Target to achieve such
milestone event, provided that subsequent milestone events that were not
achieved by the first Compound or Product for such Collaboration Target could be
met by another Compound or Product for the same Collaboration Target.  If a
milestone becomes due with respect to a Product for a specific Collaboration
Target and Indication and Modality, if applicable solely for an Extension Target
or Substitute Targets of an Extension Target, or before an earlier listed
Development milestone (i.e., milestones 1 through 4 in the above Table 1a;
milestones 1b through 4b in Table 1b; and milestones 1c through 4c in Table 1c)
became due for such Indication and Modality, if applicable, for any reason, then
the earlier listed milestones for such Indication and Modality, if applicable
solely for an Extension Target or Substitute Targets of an Extension Target,
shall be payable upon achievement of the later listed milestone.  For example,
if Milestone 4 becomes due prior to the payment of Milestone 3, then upon
achievement of Milestone 4, both the [***] Milestone 4 and the [***] Milestone 3
would be payable.  For clarity, if any of Milestones 5-10 in Table 1a is
achieved before any of Milestones 1-4, then each Milestones 1-4 (to the extent
not previously paid by BMS) would be payable on achievement of the Milestone
5-10, and similarly with respect to Milestones 5b-10b and Milestones 1b-4b in
Table 1b and Milestones 1c-4c in Table 1c.  Milestone payments for second (2nd)
and third (3rd) Indications with respect to a

 

[***] Certain information in this document has been omitted and filed separately
with the Securities and Exchange Commission. Confidential treatment has been
requested with respect to the omitted portions.

--------------------------------------------------------------------------------

given Product would be deferred until the achievement of First Commercial Sale
(in the applicable territory) for the 1st Indication with respect to such
Product. In addition, if Development is discontinued for a Product for a given
Collaboration Target before First Commercial Sale is obtained for that Product,
the previously paid milestone payments for that Product will be applied and
credited toward the milestone payments for the next Product for that
Collaboration Target in Development.  Once First Commercial Sale is obtained for
a Product for a given Collaboration Target, any deferred milestone payments for
such Collaboration Target still continuing in Development will be due.

(c)The term “Indication” as used herein means, with respect to a Compound or
Product, the use of that Compound or Product for the treatment, prevention,
mitigation or cure of: (i) any cancer with a particular organ of origin,
histology or genetic subtype; or (ii) any disease that is not a cancer but
requires a separate clinical development program to achieve Regulatory
Approval.  Different lines of therapy for the same tumor type (e.g., 1st line
NSCLC and 2nd line NSCLC) shall not be deemed different Indications.

 

13.

Sales Milestones.  Section 8.4 is hereby deleted in its entirety and replaced
with the following:

8.4Sales Milestone Payments.  

(a)For each Initial Collaboration Target, Additional Target and Substitute
Target for any Initial Collaboration Target:

(i)A milestone payment of [***] shall be payable when the total Net Sales within
a given Calendar Year of a Product in the Territory by BMS, its Affiliates and
Sublicensees first reaches more than one billion Dollars ($1,000,000,000).  

(ii)A milestone payment of [***] shall be payable when the total Net Sales
within a given Calendar Year period of a Product in the Territory by BMS, its
Affiliates and Sublicensees first reaches more than two billion Dollars
($2,000,000,000).  

(iii)A milestone payment of [***] shall be payable when the total Net Sales
within a given Calendar Year period of a Product in the Territory by BMS, its
Affiliates and Sublicensees first reaches more than three billion Dollars
($3,000,000,000).  

(iv)The sales based milestones set forth in clauses (i) through (iii) above
shall be payable one time for a particular Collaboration Target within sixty
(60) days following the end of the Calendar Year in which the first Product for
such Collaboration Target first reaches the Net Sales threshold, but in any

For clarity, the Net Sales thresholds in the tables above shall be determined on
a Product-by-Product basis.  By way of example, if the total annual Net Sales of
a Product targeting an Initial Collaboration Target in the Territory in a
particular Calendar Year are $2.8 billion, the amount of royalties payable
hereunder shall be calculated as follows (subject to any applicable reductions
under this Section 8.5):  ([***]% x $1 billion) + ([***]% x $1 billion) +
([***]% x $800 million) = $[***] million.

Notwithstanding the foregoing, subject to the last sentence of clause 8.5(f)
below, in each country where there is no Valid Claim of the Product Specific
Patents or CytomX Patent Rights that would be infringed by the sale of such
Product in such country absent a license with respect to such Product Specific
Patents or CytomX Patent Right under this Agreement, then the Base Royalty Rate
(subject to any offsets or reductions set forth below in this Section 8.5) as
applied to the sale of such Product in each such country shall be reduced by
fifty percent (50%) (i.e., the Base Royalty Rate shall be ½ the rates set forth
above in Table 2a or 2b, as applicable, above).

 

15.

Royalty Floor.   Sections 8.5(g) and 13.7(c) are hereby deleted in their

Bristol-Myers Squibb and CytomX Therapeutics Extend Worldwide Collaboration to
Discover Probody™ Therapeutics for the Treatment of Cancer and Other Diseases

 

•

Builds upon initial 2014 alliance in oncology

 

•

Includes up to eight additional targets in oncology and other therapeutic areas

 

•

CytomX to receive $200 million upfront payment

(NEW YORK and SOUTH SAN FRANCISCO, March 20, 2017) - Bristol-Myers Squibb
Company (NYSE:BMY) and CytomX Therapeutics, Inc. (Nasdaq:CTMX), a
biopharmaceutical company developing investigational Probody therapeutics for
the treatment of cancer, today announced an expansion of their 2014 strategic
collaboration to discover novel therapies that will include up to eight
additional targets using CytomX’s proprietary Probody platform.

Probody therapeutics are designed to take advantage of unique conditions in the
tumor microenvironment to enhance the tumor-targeting features of an antibody
and reduce drug activity in healthy tissues. By remaining inactive until they
are activated by proteases in the tumor microenvironment, Probody therapeutics
bind selectively to cells within tumor tissue with reduced binding to healthy
tissue, potentially improving or creating a therapeutic window. Probody
therapeutics may also have application in other diseases where proteases are
dysregulated in affected tissues.

As part of the original collaboration signed in May 2014 to discover, develop
and commercialize Probody therapeutics, Bristol-Myers Squibb selected four
oncology targets, including CTLA-4. In the collaboration to date, Bristol-Myers
Squibb has progressed the CTLA-4 Probody therapeutic to Investigational New
Drug-enabling studies and the three other programs are in the lead discovery and
optimization phase.

“CytomX’s Probody platform has enhanced our discovery research as we seek to
direct the

 

--------------------------------------------------------------------------------

therapeutic effects of immunotherapy in a more targeted approach against
tumors,” said Carl Decicco, Ph.D., Head of Discovery, Bristol-Myers Squibb. “We
look forward to working more extensively with CytomX on this innovative and
potentially disruptive approach in oncology as well as other disease areas.”

“This expanded collaboration with Bristol-Myers Squibb gives CytomX the
opportunity to further the reach of our potentially transformational Probody
technology and provides us with additional financial and strategic flexibility
to build our company,” said Sean McCarthy, D. Phil., President and Chief
Executive Officer. “With CX-072 in Phase 1/2, and CX-2009 approaching clinical
studies, our broad wholly-owned pipeline is poised for initial proof of concept
as we aim to reinvent therapeutic antibodies.”

Under the terms of the agreement, CytomX will grant Bristol-Myers Squibb
exclusive worldwide rights to develop and commercialize Probody therapeutics for
up to six additional oncology targets and two non-oncology targets.
Bristol-Myers Squibb will make an upfront payment of $200 million to CytomX and,
in addition, will provide research funding over the course of the research term.
CytomX will also be eligible to receive up to $448 million in future
development, regulatory and sales milestone payments for each collaboration
target, as well as tiered royalties from the mid-single digits to low-double
digits on net sales of each product commercialized by Bristol-Myers Squibb.

Closing of the transaction is subject to customary closing conditions, including
clearance under the Hart-Scott-Rodino Antitrust Improvements Act.

About CytomX Therapeutics

CytomX is a clinical-stage, oncology-focused biopharmaceutical company
pioneering a novel class of investigational antibody therapeutics based on its
Probody technology platform. The company

 

--------------------------------------------------------------------------------

uses its platform to create proprietary cancer immunotherapies against
clinically-validated targets, such as PD-L1, and develop first-in-class cancer
therapeutics against difficult-to-drug targets, such as CD166. Probody
therapeutics are designed to take advantage of unique conditions in the tumor
microenvironment to enhance the tumor-targeting features of an antibody and
reduce drug activity in healthy tissues. The company’s lead program, CX-072, a
wholly-owned PD-L1-targeting Probody therapeutic, is being evaluated in a Phase
1/2 study. CX-072 is part of PROCLAIM (Probody Clinical Assessment In Man), an
international umbrella clinical trial program that provides clinical trial sites
with access to the company’s novel therapies under one central protocol. The
Investigational New Drug filing for CX-2009, a first-in-class Probody drug
conjugate targeting the highly expressed tumor antigen, CD166, is targeted for
the first half of 2017. In addition to its proprietary programs, CytomX is
collaborating with strategic partners including AbbVie, Bristol-Myers Squibb
Company, Pfizer Inc., MD Anderson Cancer Center and ImmunoGen, Inc. For more
