ARTICLE 2
COLLABORATION PROGRAMS; GOVERNANCE

2.1

Overall Project.

The Parties desire to collaborate with respect to the pre-clinical development
of Designated Products, as set forth in more detail in this Article 2, in each
Indication within the Field of Use, with the goal of identifying one or more
Designated Products for clinical development and commercialization in each
Indication. As more specifically outlined herein, Penn will be responsible, in
consultation with Licensee through the JSC, for preclinical development
activities, including all IND-enabling non-clinical studies and research grade
manufacturing, and all activities set forth in the Research Plan that are not
identified therein as Licensee’s responsibilities. Licensee will be responsible
for regulatory strategy and operations, clinical development, GMP manufacture,
and commercialization of all Licensed Products. In addition, Licensee will
provide funding to Penn with respect to the Discovery Program in consideration
for certain additional rights and licenses to technologies arising from such
Discovery Program, all on the terms set forth below.

2.2

Research.

2.2.1

During the period following the Effective Date until the earlier of (a) the
expiration or termination of the Discovery Term and (b) and the completion of
the Research Plan, Licensee shall provide an amount to be agreed upon based on
the Research Plan in research and development funding (“Research Support
Amount”) to Penn to fund the Research Program. The Research Support Amount is
intended to fund Penn’s pre-clinical research and development activities under
the Research Plan through IND-enabling studies for the six named Indications as
of the Effective Date, but additional funding may be added to the Research
Support Amount by mutual written agreement of the Parties for additional
Indications added to the Research Program as provided in this Agreement. Such
Research Support Amount shall be inclusive of Penn’s standard indirect charges
and all funding shall be paid in advance of any Research Program work being
conducted. As more specifically outlined in Section 2.3.1, Licensee shall remit
such funds in each year of the Discovery Term in accordance with a payment
schedule and such funds will be allocated to Designated Product research and
development programs as set forth in the Research Plan and the Parties’
agreed-upon budget. Notwithstanding the foregoing, if a Research Plan agreed
upon by the Parties for a Research Program is in effect at the expiration of a
Discovery Term, the term shall be extended, and associated Research Support
Amount due,  solely for such outstanding Research Plan for such Indication until
completion of such outstanding Research Plan for an Indication outstanding at
the time of expiration of such Discovery Term, with such period “Program
Extension Research Term”.

2.2.2

Penn will use commercially reasonable efforts to conduct the Research Program in
accordance with the Research Plan and the other terms and conditions of this
Agreement. Without limiting the foregoing, within each Indication, Penn will be
responsible, in consultation with Licensee through the JSC, for the completion
of the Research Plan for the research and development work up to completion of
IND-enabling studies, [*]. Penn shall be responsible through the Research Plan
for the [*]. Licensee shall be responsible for the clinical and commercial
manufacture of the Designated Product in accordance with relevant cGMP.

12

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

2.2.3

The JSC shall review the Research Plan at least once per Calendar Year. The JSC
may amend the Research Plan at any time, including amendments to include further
activities, including corresponding revisions to the budget.

2.2.4

Penn shall maintain records of the results of the Research Program in sufficient
detail and in good scientific manner appropriate for patent purposes to properly
reflect all work done and results achieved. Penn will provide task-based,
scientific reports of the progress and results of the Research Program on the
schedule specified in the Research Plan or on another schedule to be agreed in
writing by the Parties. Upon Licensee’s reasonable request and at Licensee’s
cost and expense, Penn will disclose and deliver Research Results from the
Research Programs to Licensee, and will provide Licensee with such additional
information and technical assistance as may be reasonably needed for Licensee to
interpret and use such Research Results from the Research Programs. Penn shall
maintain records of the use of the funds provided by Licensee and shall make
such records available to Licensee upon reasonable notice during Penn’s normal
business hours, but not more frequently than each anniversary of the Effective
Date. All Research Results shall be solely and exclusively owned by Penn, except
to the extent (if any) that the Research Results from the Research Programs
include any jointly invented patentable inventions for which a joint ownership
interest vests in Licensee or any of its personnel under default provisions of
applicable U.S. patent Law. The Parties acknowledge that any such joint
inventions will be subject to the provisions of Section 7.4 to the same extent
as any other Research Results. In addition, unless otherwise agreed by the
Parties on a case-by-case basis, any Patent Rights corresponding to such joint
inventions: (i) will be jointly owned by the Parties; and (ii) will be subject
to this Agreement’s royalty obligations and exclusivity terms, and also to the
provisions of Article 6, [*].

2.2.5

The Parties hereby acknowledge that there are inherent uncertainties involved in
the research and development of products and such uncertainties form part of the
business risk involved in undertaking the Research Program. Accordingly, in the
event that upon completion of the portion of the Research Plan associated with a
specific Indication, the Parties do not develop or identify a suitable candidate
to propose as a development candidate for that Indication, [*].

2.2.6

Each Party will have the right to engage Third Party subcontractors to perform
certain of its obligations under this Agreement; provided that Penn’s right to
engage Third Party subcontractors is subject to Licensee’s prior written
consent, which may not be unreasonably withheld. Any subcontractor to be engaged
by a Party to perform a Party’s obligations set forth in the Agreement must meet
the qualifications typically required by such Party for the performance of work
similar in scope and complexity to the subcontracted activity and will enter
into such Party’s standard nondisclosure agreement consistent with such Party’s
standard practices which agreement shall be as least as protective as the
nondisclosure obligations set forth herein. Any Party engaging a subcontractor
hereunder will remain responsible and obligated for such activities and will not
grant rights to such subcontractor that interfere with the rights of the other
Party under this Agreement. Furthermore, if Penn engages any subcontractor to
perform any activities that would otherwise be performed by the Wilson
Laboratory, [*].

 Further, Licensee may not [*].

(iii)In the event that the Parties have a good faith scientific dispute over
whether such Next Generation Indication Program has [*] to the existing Licensed
Product for such Indication, then Licensee shall provide written notice to Penn
during such First Notice Period for such Next Generation Indication Program.
 Upon receipt of such notification, the JSC shall meet and confer on such Next
Generation Indication Program.  In the event that the Parties cannot resolve
such dispute at the JSC, then such dispute may be referred by either Party to a
panel of [*].  Each Party [*] within [*] of their appointment.  The panel of [*]
can only determine whether such Next Generation Indication Program has [*] to
the existing Licensed Product for such Indication.  The determination of the
panel shall not exceed [*], and the determination made by such panel shall be
final, binding and non-appealable on both Parties.  No discovery other than an
exchange of relevant documents may occur in the proceeding, and the Parties
agree to act in good faith to promptly exchange the relevant documents.  The
cost of such panel and proceeding shall be borne equally by the Parties. The
panel of the experts chosen in accordance with these provisions will not have

2.6.2

Licensee Initiated Programs.

(a)

During the Discovery Term, if Licensee wishes to include a new Gene Therapy
Product development program for a CNS Monogenic Rare Disorder to be conducted in
the Wilson Laboratory for a New Indication, then Licensee may

17

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

formally make such request in writing to Penn during the Discovery Term, as
applicable. Penn may decline to progress with the program for the following
reasons, assuming such reasons exist without any breach of Section 2.6.1: (i)
[*]; (ii) [*]; (iii) [*]; (iv) [*]; (v) [*]; or (vi) [*] (each of (i) through
(vi), a “Dispositive Rejection Condition”). If the New Indication is not subject
to a Dispositive Rejection Condition, Penn will then develop and propose within
[*] a work plan and budget for the preclinical development costs through
IND-enabling studies to be conducted at Penn for such program including any
budget therefor. Any such agreed budget will be added to the pre-existing
Research Support Amount. Licensee shall have [*] to negotiate and, if
applicable, accept such work plan and budget. If accepted, within [*] of
Licensee’s acceptance of such budget, the definition of “Indication” (and the
Research Program and Research Plan) will be amended to include the New
Indication, and (for purposes of any provisions of this Agreement other than
Section 2.6.1) Licensee will thereupon be deemed to have exercised a New
Indication Option for such New Indication, obligating Licensee to pay a New
Indication Option Fee in accordance with Section 4.1.2. If the Parties are
unable to agree on a new work plan and budget within such time period, [*]. If a
Dispositive Rejection Condition no longer exists, then Penn will provide
Licensee with notice and provide Licensee with the option to include such
proposed program consistent with the mechanics set out above. For clarity, [*].

(b)

In the event that Licensee proposes to Penn in Section 2.6.2(a) a Next
Generation Indication Program for an Existing Research Plan or completed
Research Plan for an Indication, then this Section 2.6.2(b) shall apply.  The
Parties acknowledge and agree that this Section 2.6.2(b) is intended to apply
for the development of new Gene Therapy Products utilizing Next Generation
Technology.  For further clarity, [*].

(i)Upon a proposal to Penn by Licensee of a Next Generation Indication Program,
Licensee shall have the right to include any Next Generation Indication Program
in the License granted under this Agreement by exercising a New Indication
Option under Section 2.6.1(a), provided, however, [*]. For clarity, [*]. Penn
shall have [*] to conduct such development work pursuant to a new Research
Program and Research Plan for such Next Generation Indication Program. For
clarity, [*].

(ii)If, despite good faith negotiations, the Parties fail to negotiate the work
plan, New Program Budget or specific gene replacement transgene within [*] of
Licensee’s notice of its desire to exercise of such New Indication Option for
such Next Generation Indication Program, Licensee shall be free to conduct such
development work for such Next Generation Indication Program.

2.6.3

Exercise and Termination of  New Indication Options. The Parties acknowledge and
agree that, beginning on the Restatement Date, Licensee shall have a total of
eleven (11) New Indication Options under Sections 2.6.1(a) and/or 2.6.2, which
Licensee may elect to exercise at any time until the expiration or termination
of the Discovery Term. Upon the earlier of (i) exercise by Licensee of eleven
(11) New Indication Options pursuant to Section 2.6.1(a) and 2.6.2 and (ii)
expiration or termination of the Discovery Term,  Penn shall have no obligation
under Section 2.6.1(a) or 2.6.2 to perform any additional New Program, grant a
license to any additional New Indication or provide a First Notice to Licensee
of any New Program after such period.  For clarity, [*]. Notwithstanding the

18

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

foregoing, Licensee may exercise a New Indication Option for a Next Generation
Indication Program under Section 2.6.1(b) [*].

2.7

Exclusive CNS Option.

Without limiting Section 2.11.1, during the period starting on the Effective
Date and ending at the earlier of: (a) [*]or (b) [*], Penn shall not grant any
right to any commercial Third Party to any Patent Rights [*] for a Gene Therapy
Product for any Available Rare CNS Indications without first notifying Licensee
in writing, in which case Licensee shall have [*] from receipt of such notice to
exercise its option with respect to such New Indication in accordance with the
New Indication Option procedure set forth in Section 2.6.1. “Available Rare CNS
Indication” means an Indication in the CNS Field (as defined below) to the
extent such New Indication is not listed on Exhibit D as specifically excluded
from the CNS Field.  Licensee acknowledges that the foregoing option will not
apply to those New Indications set forth on Exhibit D. In addition during the
Discovery Term and prior to Licensee’s exercise of its eleven (11) New
Indication Options, subject to the terms of this Agreement, [*].  For clarity,
[*].

2.8

Manufacturing Patent Rights Option.

During the Discovery Term, Licensee will have the option to include in the
License Manufacturing Patent Rights. During the Discovery Term, Penn, through
the Wilson Laboratory, shall notify Licensee once every [*] of any available
candidate Manufacturing Patent Rights applicable to the Field of Use for any of
the Indications (“Manufacturing Patent Rights Package”) (where “available” means
that the Specified Obligations do not prevent such candidate Manufacturing
Patent Rights from being licensed to Licensee).  For clarity, [*]. During the
Discovery Term, on a Licensed Product-by-Licensed Product per Indication basis,
Penn grants to Licensee an option to a non-exclusive license to Manufacturing
Patent Rights for the applicable Licensed Product(s) for the Indication in the
Field of Use. The option on a Licensed Product-by-Licensed Product and
Indication-by-Indication basis shall be exercisable at Licensee’s discretion at
any time during the Discovery Term and, if longer, until [*]. Such option will
expire at the end of the exercise period described in the preceding sentence.
Upon exercise of such option, a new Exhibit A-2 shall be created by the Parties
to include the relevant licensed Manufacturing Patent Rights.  For clarity, [*].

2.9

Natural History Studies.

During the Discovery Term, Penn Orphan Disease Center, through the Wilson
Laboratory, shall conduct natural history studies relating to the Research
Program with funding from the Licensee and additional commercial Third Parties,
subject to the Parties’ having reached mutual agreement upon the terms of the
funding, non-exclusive rights to the data arising from such studies and other
terms in a clinical research agreement.  For clarity, [*].

2.10

Rights to Technologies arising from Discovery Program.

2.10.1

Generally. It is anticipated that Licensed Product development under the
Research Program  will include the use of most scientifically appropriate and
available Next Generation Capsids and other technologies Controlled by Penn
arising from the Discovery Program. As used throughout this Section 2.10,
“available” means that the Specified Obligations do not prevent the Next
Generation Capsid from being offered or licensed to Licensee as contemplated
herein. For clarity, [*].

19

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

2.10.2

Ongoing Research Programs and Product Lock.

(a)

During the term of the Discovery Program and in accordance with Section 2.10.4,
Penn, through the Wilson Laboratory, will notify Licensee of any available Next
Generation Capsids and Discovery Patent Rights that may be applicable to a
Licensed Product under development in a Research Program for an Indication.

(b)

On an Indication-by-Indication basis and Licensed Product-by-Licensed Product
basis (for clarity, whether or not the applicable Licensed Product arises from a
Research Program), Licensee shall provide notification to Penn upon the
selection of the [*] for a Licensed Product for such Indication.  [*] (“Product
Lock”) shall occur [*].

(c)

Upon Product Lock on an Indication-by-Indication and Licensed
Product-by-Licensed Product basis, a new Exhibit A-1 shall be created upon
Penn’s receipt of Licensee’s request, which request shall specify the Penn
Patent Rights A and Patent Rights B that cover the applicable Specified Licensed
Product for the applicable Indication.

2.10.3

After Product Lock.  In the event that  following Product Lock for a Specified
Licensed Product for an Indication, a newly discovered [*] for such Specified
Licensed Product for such Indication, Exhibit A-1 shall be amended upon [*],
which request shall specify the additional Penn Patent Rights B that cover the
applicable Specified Licensed Product for such Indication.  Notwithstanding the
above, to the extent the technology covered by such newly discovered [*] is Next
Generation Technology, then (a) [*], or (b) [*].

2.10.4

Discovery Data Packages. During the Discovery Term, Penn, through the Wilson
Laboratory, shall notify Licensee [*] of any available Next Generation Capsids
and Discovery Patent Rights in the Field of Use for the Indications and provide
Licensee a Next Generation Capsid Data Package.

2.11

Licensing Exclusivity.

2.11.1

Subject to Penn’s retained rights in Section 3.2, Penn shall not license, or
grant any other rights in or to, any Patent Rights conceived and reduced to
practice by the Wilson Laboratory during the [*] in the conduct of the [*] to
another Third Party for an Indication for a period of the greater of (a) [*]
from Penn’s initiation of work under the Research Program for such Indication
and (b) [*] from Product Lock for such Indication (“Licensing Exclusivity
Period”) provided that Penn conducts the Research Plan [*] for such product
candidate for such Indication under this Agreement (further provided that the
Licensing Exclusivity Period will apply if Penn is unwilling or unable to
perform [*], including through the use of a subcontractor).  At the conclusion
of the Licensing Exclusivity Period, or earlier if the Research Plan for such
Indication has been terminated, Penn shall have the right to license any [*] for
the Indication [*]. For clarity, [*]. Notwithstanding the foregoing, the
restriction and Licensing Exclusivity Period set forth in Section 2.11.1 shall
not apply to a Next Generation Indication Program that is not included in the
License as a result of the application of Section 2.6.1(b)(ii), and Penn shall
be free to license to a Third Party the Discovery Patent Rights for such Next
Generation Indication Program [*].

20

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

2.12

Limited Collaboration Exclusivity.

On an Indication-by-Indication basis during the Discovery Term (or Program
Extension Research Term solely with respect to such Designated Product for an
Indication subject to such Program Extension Research Term) until the earlier
of: (a) DTP for such Indication for a Designated Product plus an additional one
(1) year after achievement of DTP for such Indication or (b) filing by Licensee
of an IND for a Licensed Product for such Indication plus an additional one (1)
year after such filing, Penn will ensure that the Wilson Laboratory shall not
collaborate with any commercial Third Party to develop another Gene Therapy
Product for the same Indication (as that term is defined as of the Effective
Date and as it may be updated throughout the Agreement when additional New
Indications are included pursuant to this Agreement) (“Limited Collaboration
Exclusivity Covenant”). Notwithstanding the foregoing, the Limited Collaboration
Exclusivity Covenant shall end on an Indication-by-Indication and Licensed
Product-by-Licensed Product basis upon the earlier of: (a) [*] after the end of
the portion of the funded Research Program at Penn associated with that specific
Indication, (b) [*] or (c) [*].

2.13

Program Failure.

In the event that the portion of the Research Program associated with any
Licensed Product for any Indication fails at a key decision point during the
Research Program, as such failure is objectively defined in the work plan for
such project, and a decision is subsequently made by the Licensee to discontinue
further development of the program for such Indication (“Failed Indication”),
any remaining Research Support Amount allocated for the Failed Indication
program (minus wind-down and non-cancellable expenses) will be reallocated to
Licensed Product development programs for other Indications selected by Licensee
under the Research Program budgeted during the subsequent twelve (12) month
period. Such Failed Indication will be removed promptly from the Indication
definition of the Agreement, with written confirmation of such reversion of
rights promptly provided by Licensee to Penn. In addition any [*] shall

(b)

Third Party Licenses.

(i)If after the Effective Date Licensee determines upon the advice of outside

(ii)Licensee may deduct from any Royalty payments due to Penn under Section
4.3.1 of this Agreement an amount equal to [*] (the “Anti-Stacking Percentage”)
of any Royalty paid by Licensee to a Third Party on [*] of a particular Licensed
Product in a particular country during a Calendar Quarter under a Third Party
license obtained by Licensee pursuant to Section 4.3.4(b)(i).

(iii)In the event that one or more Generic Product(s) with respect to a
particular Licensed Product enter(s) the market in a particular country, and
such Generic Product(s) in the aggregate have a market share of [*] or more in
that country, Licensee may reduce the Royalty payments for Sales of such
Licensed Product in such country by [*]; provided that if Licensee reduced the
Royalty payments under this Section 4.3.4(b)(iii), Licensee shall resume making
Royalty payments without reduction under this Section 4.3.4(b)(iii) as of the
earlier of (a) no Generic Product being sold for at least [*] in such country
and (b) a court of competent jurisdiction determines that a Valid Claim of a
Penn Patent Right is valid and infringed by such Generic Product in such
country.

(iv)Notwithstanding the foregoing, in no event will the deductions under this

4.7

Late Payments.

In addition to any other remedies available to Penn, including the right to
terminate this Agreement as provided in Section 10.3, any failure by Licensee to
make a payment within [*] after the date when due shall obligate Licensee to pay

the highest rate allowed by Law, whichever is lower.

4.8

4.10

Books and Records.

Licensee will keep accurate books and records of all Licensed Products
developed, manufactured, used or sold and all Sublicenses, collaboration
agreements and joint venture agreements entered into by Licensee that involved
Penn Patent Rights. Licensee will preserve these books and records for at least

notice, key personnel, books and records will be made reasonably available and
will be open to examination by representatives or agents of Penn during regular
office hours to determine their accuracy and assess Licensee’s compliance with
the terms of this Agreement, provided that Licensee shall not have an obligation
to provide access more than once in any given [*] period.

4.11

Audits.

In addition to the right of Penn to examine the books and records and interview
key personnel as provided in Section 4.10 above, Penn, at its own cost, through
an independent auditor reasonably acceptable to Licensee (and who has executed

as needed to report its audit conclusions to Penn), may inspect and audit the
relevant records of Licensee pertaining to the calculation of any Development
Milestone Payments, Commercial Milestone Payments, Royalties and Penn Sublicense
Income due to Penn under this Agreement. Licensee shall provide such auditors
with access to the records during reasonable business hours. Such access need
not be given to any such set of records more often than once each year or more

Licensee within [*] after Penn receives the audit report. [*].

4.12

ARTICLE 5
CLINICAL DEVELOPMENT, REGULATORY AFFAIRS; COMMERCIALIZATION

5.1

Development Plan.

Licensee shall provide Penn with a development plan no later than [*] during the
Term. The development plan shall include a timeline for detailed activities to
be conducted by Licensee, its Affiliates and Sublicensees, and Licensee shall
provide Penn with [*] progress reports regarding achievements and activities
under such development plan. For clarity, [*].

5.2

Clinical.

Licensee shall have the first right to sponsor all clinical activities and lead
regulatory interactions for the Licensed Products for each Indication under this
Agreement. Without limiting the foregoing, Licensee will have the first option,
but not an obligation, to conduct a FIH Clinical Study for each Licensed Product
developed under the Research Program. Licensee will consider in good faith using
Penn as a study site for one or more studies where Penn can reasonably
demonstrate that Penn’s capabilities and costs are reasonably comparable to
other potential study sites. If Penn (in its sole discretion) is willing and
able to conduct a Clinical Study for a Licensed Product developed under the
Research Program, the Parties will negotiate a separate clinical trial agreement
and a separate clinical trial budget prior to initiation of such Clinical Study.
For clarity, any Clinical Study funding by Licensee shall be separate and in
addition to the Research Support Amount.

5.3

Commercialization.

Licensee will have sole responsibility for and sole decision-making over all
commercialization activities of the Licensed Products for the Indications in the
Field of Use, and will be solely responsible for the associated costs of such
commercialization activities.

34

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

5.4

Manufacturing.

Except as otherwise provided in this Agreement or in the Research Plan, Licensee
will have responsibility for and decision-making authority over all
manufacturing activities and associated costs for the clinical development
(including GMP manufacturing for clinical trials) and commercialization of the
Licensed Products in the Field of Use for the Indications post-DTP for such
Licensed Product. Penn will have responsibility and decision-making authority
over manufacturing activities for pre-clinical manufacturing, [*] and at
Licensee’s cost.

5.5

Regulatory.

5.5.1

Subject to Section 2.14.1(b), Licensee will have responsibility for and
decision-making over regulatory activities for the Licensed Products for the
Indications in the Field of Use. Licensee will have the right to conduct all
communications with Regulatory Authorities, including all meetings, conferences
and discussions (including advisory committee meetings), with regard to Licensed
Products for the Indications in the Field of Use; [*]. Licensee will lead and
have control over preparing and submitting all regulatory filings related to the
Licensed Products for the Indications in the Field of Use, including all
applications for Regulatory Approval, provided, however, that Licensee shall
provide Penn with copies of all such applications prior to submission to the
extent such submission includes Research Results or any Confidential Information
of Penn. Licensee will own any and all applications for Regulatory Approvals
(including INDs), Regulatory Approvals, and other regulatory filings related to
the Licensed Product for the Indication in the Field of Use, which will be held
in the name of Licensee or its designees.

5.5.2

Penn will cooperate with any reasonable request from Licensee with respect to
obtaining any Regulatory Approval for a Licensed Product for the Indication in
the Field of Use including, at Licensee’s cost: (a) [*], (b) responding to
questions raised by Licensee, and (c) [*].

5.6

General Diligence.

Licensee will use Commercially Reasonable Efforts to actively develop, obtain
Regulatory Approval and commercialize at least one Licensed Product in each
Indication within the Field of Use.

corresponding Achievement Date for each Licensed Product:

Diligence Event

Achievement Date

[*]

[*]

[*]

[*]

[*]

[*]

35

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

Penn acknowledges that the timeline for each Achievement Date is based on the
assumption that development and commercialization of a Licensed Product does not
encounter material regulatory or other delays for reasons outside of Licensee’s
reasonable control. Where such circumstances exist, Penn agrees to negotiate in
good faith with Licensee, upon Licensee’s written request and provided such
request is made at least [*] prior to the Achievement Date for a Diligence
Event, an extension of the Achievement Date for a Diligence Event for such
Licensed Product as reasonably requested by Licensee. If the Parties have not
agreed on a requested extension within [*] of such request, [*].

To the extent Licensee has achieved any Diligence Event by the corresponding
Achievement Date in relation to a given Licensed Product for an Indication,
Licensee will be deemed to have also met its diligence obligations under Section
5.6 with respect to such Licensed Product and its associated Indication(s)
through the corresponding Achievement Date.

5.9

Progress Reports.

5.9.1

After performance of the Research Plan by Penn but prior to the First Commercial
Sale of a Licensed Product in the respective Indication, Licensee on [*], but in
no event later than [*], shall submit to Penn a progress report (each, a
“Progress Report”) covering Licensee’s (and any Affiliates’ and Sublicensees’)
activities related to the development of all Licensed Products in each
Indication and the obtaining of Regulatory Approvals necessary for
commercialization of Licensed Products.

number and e-mail address for a principal point of contact at each such
Sublicensee who is responsible for administering the Sublicensee.

ARTICLE 6
INTELLECTUAL PROPERTY

6.1

Patent Filing Prosecution and Maintenance.

6.1.1

Penn Patent Rights, Discovery Patent Rights and DRG Patent Rights will be held
in the name of Penn and obtained with counsel selected by Penn and reasonably
acceptable to Licensee (“Patent Counsel”). Penn shall control all actions and
decisions with respect to the filing, prosecution and maintenance of Penn Patent
Rights, Discovery Patent Rights and DRG Patent Rights. Penn will provide
Licensee with advance copies of filings of the Penn Patent Rights, Discovery
Patent Rights and will consider in good faith reasonable comments and
suggestions by Licensee, and [*] (collectively, the “Product Specific

36

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

Patent Rights”), Penn will incorporate any reasonable comments or suggestions by
Licensee with respect to same. Penn will instruct Patent Counsel to copy
Licensee on all correspondence related to Penn Patent Rights A and Penn Patent
Rights B (including copies of each patent application, office action, response
to office action, request for terminal disclaimer, and request for reissue or
reexamination of any patent or patent application) and to interact with Licensee
with respect to the preparation, filing, prosecution and maintenance of Penn
Patent Rights A and Penn Patent Rights B.  Penn has the right to take action to
preserve rights and minimize cost [*], and will use reasonable efforts to not
allow any Penn Patent Rights and DRG Patent Rights for which Licensee is
licensed and is underwriting the costs to lapse or become abandoned without
Licensee’s written authorization under this Agreement, [*], provided that, Penn
shall have no requirement to file, prosecute, or maintain Penn Patent Rights,
Discovery Patent Rights or DRG Patent Rights if Licensee is not current with the
Patent Cost obligations as set forth in this Agreement. For the purposes of this
Agreement, “maintenance” of the Penn Patent Rights, Discovery Patent Rights and
DRG Patent Rights includes [*], provided Penn’s participation in such
proceedings is undertaken in good-faith consultation with Licensee. For further
clarity, [*] will be handled pursuant to the provisions of Section 6.3.

6.1.2

Licensee has the right to request a country filing via a written request to Penn
[*] prior to the deadline set by the patent office in the territory in which
filing is to take place (“Prosecution Request”), and Penn shall in connection
with Section 6.1.1 provide written notice to Licensee of filing, prosecution and
maintenance with respect to the Penn Patent Rights. If Penn files a patent
application, prosecutes or maintains any Penn Patent Rights in any country,
Licensee shall, in connection with Section 6.2, be responsible for its pro rata
share of such filing, prosecution or maintenance of the Penn Patent Right,
unless Licensee provides written notice to Penn of its election to abandon such
Penn Patent Right. Upon written notice to Penn of Licensee’s election to abandon
any such Penn Patent Right in any such country, such Patent Rights for such
country will not be part of Penn Patent Rights and therefore not subject to this
Agreement, including the License, and Licensee will have no further rights or
license to them in such country.

6.1.3

In the event that DRG Technology [*], then Penn may file and prosecute a Patent
Right that covers [*]; provided, however, that if Penn files a [*].

6.2

Patent Costs.

6.2.1

Subject to Section 6.2.3, within [*] of the Restatement Date, Licensee will
reimburse Penn for all out-of-pocket costs for the filing, prosecution and
maintenance of Penn Patent Rights, Discovery Patent Rights and DRG Patent
Rights, including all accrued attorney fees, expenses, official and filing fees
(“Patent Costs”) for Discovery Patent Rights and DRG Patent Rights, incurred
prior to the Restatement Date that have not otherwise been reimbursed by other
licensees on a pro rata basis (“Historic Patent Costs”). The amount of Historic
Patent Costs is approximately [*].  For clarity, [*].

6.2.2

Licensee will bear all Patent Costs incurred during the Term (“Ongoing Patent
Costs”), on a pro rata basis (as described below) where applicable.  For Penn
Patent Rights, Discovery Patent Rights and DRG Patent Rights licensed or
optioned to more than one licensee, Licensee shall be responsible for payment to
Penn of a pro rata share of such Ongoing Patent Costs based on the number of
licensees for such Penn Patent Rights, Discovery Patent Rights and DRG Patent
Rights (which Penn will disclose to Licensee

37

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

upon Licensee’s exercise of an applicable option, and whenever such number
changes, and at any other time upon Licensee’s reasonable written request).

6.2.3

At any time, at Penn’s request, Licensee shall pay its relevant share in advance
the Patent Counsel’s estimated costs for undertaking material patent actions
before Penn authorizes the Patent Counsel to proceed (“Advance Payment”).
Notwithstanding whether Licensee makes an Advance Payment for any patent action,
Licensee shall bear all Patent Costs incurred during the Term (on a pro rata
basis as applicable) and shall pay such amounts within [*] of receipt of invoice
for such patent actions. For clarity, [*].

6.2.4

In the event that Licensee provides Penn at least [*] advance written notice to
elect not to pay Historic Patent Costs or Ongoing Patent Costs for any Penn
Patent Right, Discovery Patent Right or DRG Patent Right in any country, upon
the effective date of such notice, such patent or patent application shall no
longer be part of the License granted to Licensee in Section 3.1 or the Penn
Patent Rights for purposes of this Agreement (including the provisions of this
Section 6.2) and Licensee shall not be entitled to receive a license to such
Penn Patent Right, Discovery Patent Right or DRG Patent Right in such country in
the future.  In addition, for such rejected Penn Patent Right or Discovery
Patent Right, the Licensing Exclusivity Period, Manufacturing Patent Rights
option, or ability to add such rejected Penn Patent Right or Discovery Patent
Right to the license grant as set forth in Section 2.10.3 shall terminate
immediately.

6.2.5

Licensee shall also have the right, on a DRG Patent Right-by-DRG Patent Right
and country-by-country basis, to (i) elect not to fund at the time of
disclosure, or (ii) elect not to continue to fund, in each case (i) and (ii),
its pro rata share (as determined pursuant to Section 6.2.2 above) of the Patent
Costs with respect to any DRG Patent Right(s) in a particular country, which
election may be made by Licensee upon [*] prior written notice to Penn (“DRG
Election Notice”). If Licensee delivers a DRG Election Notice to Penn, following
the expiration of such [*] period, Licensee shall have no further obligation to
pay Ongoing Patent Costs with respect to any DRG Patent Right identified in such
DRG Election Notice in any country identified in such DRG Election Notice and
any such Patent Right in any such country shall thereafter be excluded from the
DRG Patent Rights.

6.3

Infringement.

6.3.1

If either Party believes that an infringement by a Third Party with respect to
any Penn Patent Right or DRG Patent Right is occurring or may potentially occur,
the knowledgeable Party will provide the other Party with (a) written notice of
such infringement or potential infringement and (b) evidence of such
infringement or potential infringement (the “Infringement Notice”). Licensee
shall [*] without first obtaining the written consent of Penn, which consent
will not be unreasonably withheld. If Licensee [*], then Licensee’s right to
initiate a suit under Section 6.3.2 below will terminate immediately without the
obligation of Penn to provide notice to Licensee. Both Penn and Licensee will
use their diligent efforts to cooperate with each other to terminate such
infringement without litigation.

6.3.2

If infringing activity [*] has not been abated within [*] following the date the
Infringement Notice for such activity was provided, then (except as otherwise
provided in Section 6.3.4) during [*], the “Exclusive Penn Patent Rights”), and
the infringement is [*], Licensee may institute suit for patent infringement of
an [*] against the infringer after providing Penn (a) [*]and (b) [*]. For
clarity, [*]. Penn may voluntarily join such suit at Licensee’s

involuntarily joined other than by Licensee, then Licensee [*]. Licensee shall
be free to enter into a settlement, consent judgment or other voluntary
disposition, provided that any settlement, consent judgment or other voluntary
disposition that (i) [*] or (ii) [*]. Licensee’s request for such approval shall

such settlement, and any other information material to such settlement. Penn
shall provide Licensee notice of its approval or denial within [*] of any
request for such approval by Licensee, provided that (x) [*] and (y) [*].

suit against the infringer, then Penn [*]. If Penn [*] then Licensee may [*].

6.3.4

Notwithstanding Sections 6.3.2 and 6.3.3, (a) in the event that any Penn Patent
Rights are infringed by a Third Party [*] or (b) if any of the infringed Penn
Patent Rights are [*], the Parties shall discuss, and will mutually agree, in
writing, as to how to handle such infringement by such Third Party. Furthermore,
with respect to any Penn Patent Rights A that are not Product Specific Patent
Rights, and/or any Penn Patent Rights B, Licensee may [*]. For clarity, [*].
Penn shall [*] right to enforce (i) Penn Patent Rights B, unless otherwise
agreed in writing by the Parties ([*]), and (ii) Manufacturing Patent Rights.

For any portion of the recovery or settlement, other than for amounts
attributable and paid as enhanced damages for [*]:

(a)

for any suit that is initiated by Licensee and in which Penn was not a party in
the litigation, Penn shall receive [*] of the recovery and the Licensee shall
receive the remainder; and

(b)

for any suit that is initiated by the Licensee or Penn and that the other Party
joins voluntarily ([*]) or involuntarily, the non-initiating Party shall receive
[*] of such recovery, while the initiating Party shall receive the remainder.

For any portion of the recovery or settlement paid as enhanced damages for [*]:

(c)

for any suit that is initiated by Licensee or Penn and the other Party joins
voluntarily ([*]) or involuntarily, Penn shall receive [*] and Licensee shall
receive the remainder; and

(d)

for any suit that is initiated by Licensee and in which Penn was not a party in
the litigation, Penn shall receive [*] and Licensee shall receive the remainder.

For any portion of the recovery or settlement received in connection with any
suit that is initiated by Penn and in which Licensee was not a party in the
litigation, any recovery in excess of litigation costs will belong to Penn.

6.3.6

Each Party will reasonably cooperate and assist with the other in litigation
proceedings instituted hereunder but at the expense of the Party who initiated
the suit (unless such suit is being jointly prosecuted by the Parties). For
clarity, [*]. If Penn is subjected to Third

Confidential Information.

Licensee shall not disclose Confidential Information (as defined below) to Penn
unless it is anticipated to be necessary or useful to the performance of the
Research Program or is reasonably responsive to Licensee’s reporting obligations
under this Agreement or any other request of Penn. Except to the extent
expressly authorized by this Agreement or otherwise agreed in writing, the
Parties agree that, during the Term and for [*] thereafter, the receiving Party
(the “Receiving Party”) and its Affiliates will keep confidential and will not

Termination For Cause.

10.3.1

the right and option to terminate this Agreement on an Indication-by-Indication
basis for the Indication in which diligence has not been achieved, upon written
notice, with immediate effect.

10.3.2

In addition to all other remedies available to it, Penn may terminate this
Agreement (a) upon at least [*] written notice, upon a failure of Licensee to
pay the Research Support Amount for the Research Program when due pursuant to

10.4

Effects of Termination.

10.4.1

Notwithstanding the termination of this Agreement, the following provisions
shall survive: Sections [*].  Furthermore, where this Agreement is terminated in
relation to fewer than all of the Indications or Licensed Products (as provided

liability that, at the time of termination, has already accrued hereunder, or
which is attributable to a period prior to the effective date of such

pursuing all rights and remedies it may have hereunder or at Law or in equity
with respect to any breach of this Agreement nor prejudice either Party’s right
to obtain performance of any obligation.

10.4.3

If this Agreement is terminated for any reason, all outstanding Sublicenses

Penn under the assigned Sublicenses will not be greater than the duties of Penn
under this Agreement, and the rights of Penn under the assigned Sublicenses will
not be less than the rights of Penn under this Agreement, including all
financial consideration and other rights of Penn. Penn may, at its reasonable
discretion, amend such outstanding Sublicenses to contain the terms and
conditions found in this Agreement. If Penn requests that Licensee assign to
Penn all Regulatory Approvals for the Licensed Product upon termination of this
]Agreement by Licensee under Section 10.2 or by Penn under Section 10.3, then
Licensee agrees to negotiate the terms of such an assignment in good faith (it
being understood that the foregoing will not preclude Licensee from requiring
Penn to pay commercially reasonable consideration for such assignment). [*].

10.4.4

Within [*] of termination of this Agreement or any Indication (other than
termination by Licensee pursuant to Section 10.3.3), Licensee shall pay Penn all
costs through the effective termination date per the budget of the Research Plan
as well as all commitments related to the performance of the Research Plan and
Discovery Program (i.e., all costs or non-cancellable commitments incurred prior

costs and non-cancellable commitments as they arise) incurred by Penn under this
Agreement, or for the terminated Indication, as applicable.

10.4.5

Upon termination of this Agreement, the License immediately terminates and
Licensee, its Affiliates and Sublicensees will promptly cease selling the
Licensed Product(s) subject to such termination. Each Party will return (or
destroy, as directed by the other Party) all data,

47

files, records and other materials containing or comprising the other Party’s

records, and other materials for archival and legal compliance purposes.
