7.1    Conditions for Permitting Independent Activities. For each Optioned
Program, if, subject to Section 3.1(a) and 6.2(a), either Party desires to
conduct any Development activities in, or Manufacturing activities for, its
Respective Territory that (a) the other Party does not agree to include in the
applicable R&D Plan and Budget or the applicable Global Manufacturing Plan and
Budget, as applicable, in either case, following completion of the dispute
resolution process set forth in Section 1.5(b)(ii)(B) and (b) would not be
reasonably expected to have a material adverse effect on the Development or
Commercialization of any Optioned Molecule or Optioned Product in the Respective
Territory of the other Party; provided that in no event shall any Clinical Trial
that is required for Regulatory Approval in the Independent Activities Party’s
Respective Territory be reasonably expected to have a material adverse effect on
the Development or Commercialization of any Optioned Molecules or Optioned
Product in the Respective Territory of the other Party (any such activities,
“Independent Activities”), then Section 7.2 shall apply.
7.2    Independent Activity Plans. For each Optioned Program, if the conditions
set forth in Section 7.1 apply, then:
(a)    the Party that desires to conduct the Independent Activities (the
“Independent Activities Party”) shall provide the JDC with a written plan for
conducting such Independent Activities (“Independent Activities Plan”), which
Independent Activities Plan shall describe the applicable Independent Activities
in reasonable detail, including for Development activities, a description of the
applicable Clinical Trial and expected data to be generated therefrom;
(b)    within […***…] Business Days after receipt of such Independent Activities
Plan, the JDC shall meet to discuss any comments of the other Party with respect
to such Independent Activities Plan, and the Independent Activities Party shall
consider any such comments in good faith;
(c)    within […***…] Business Days after the occurrence of such meeting of the

(a)    Any Independent Activities shall be carried out in accordance with the
applicable Independent Activities Plan that was last reviewed by the JSC in
accordance with Section 7.2(d); provided that non-substantive changes do not
have to be reviewed by the JSC. For clarity, if the Independent Activities Party
desires to carry out additional substantive Independent Activities that are not
set forth in an Independent Activities Plan that was reviewed by the JSC in
accordance with Section 7.2(d), then such Independent Activities Party shall
follow the procedures set forth in Section 7.2 with respect to such additional
Independent Activities.
(b)    Subject to Section 7.5 or in the case of Manufacturing-related
activities, as otherwise set forth in a Supply Agreement, the Independent
Activities Party shall be solely responsible for all costs and expenses for
Independent Activities carried out by or on behalf of such Independent
Activities Party.
(c)    The applicable Independent Activities Party shall keep the JDC reasonably
informed regarding the progress of Independent Activities, including by

and (ii) may be used by the non-Independent Activities Party on the applicable
Optioned Product label(s) and disclosed by the non-Independent Activities Party
to any Regulatory Authority as required by Applicable Law or required by such
Regulatory Authority in connection with the applicable Optioned Product or
applicable Optioned Program, in each case, as being Developed and Commercialized
by the non-Independent Activities Party, without payment of any fee or
consideration to the Independent Activities Party and without any such
additional agreement as contemplated in Section 7.5.
7.5    Buy-In for Independent Activities Data or Independent Activities
Regulatory Documentation. The non-Independent Activities Party with respect to
any Independent Activities Data or Independent Activities Regulatory
Documentation may provide written notice to the Independent Activities Party
that it desires to terminate the restrictions on use of such Independent

8.2    Gilead’s Option Rights.
(a)    Option Grant. For each Galapagos Program, subject to Section 8.2(d),
Galapagos hereby grants to Gilead an exclusive option to obtain the exclusive
and co-exclusive licenses described in Section 8.3 with respect to such
Galapagos Program and all Galapagos Molecules and Galapagos Products included in
such Galapagos Program (each, an “Option”). The Option with respect to each
Galapagos Program shall be effective for the period beginning on (i) the
Effective Date, for any Galapagos Program in existence as of the Effective Date,
(ii) the date of acquisition by Galapagos or its applicable Affiliate, for any
Acquired Galapagos Program that constitutes a Galapagos Program as of such date
of acquisition, or (iii) the date on which a Galapagos Program comes into
existence, for any Galapagos Program arising after the Effective Date from
Pre-Program Activities (including, for clarity, with respect to any Acquired
Galapagos Program that did not constitute a Galapagos Program upon acquisition),
and, in each case ((i) through (iii)), ending on the earliest to occur with
respect to such Option of (A) the applicable Option Exercise Closing with
respect to each country in the Territory, (B) the end of the applicable Option
Exercise Period prior to delivery by Gilead of an Option Exercise Notice for
such Option, (C) the termination of such Option pursuant to Section 8.2(e), (D)
the expiration or termination pursuant to ARTICLE XIV of this Agreement in its
entirety or with respect to all Galapagos Molecules and all Galapagos Products
in the applicable Galapagos Program, and (E) the third anniversary of the end of
the Collaboration Term (such effectiveness period with respect to each such
Option, the “Galapagos Program Period”).
(b)    Option Exercise Notice; Option Exercise Period.
(i)    With respect to each Galapagos Program (and all Galapagos Molecules and
Galapagos Products included in such Galapagos Program), Gilead may exercise the
Option at any time during the applicable Option Exercise Period for such
Galapagos Program by delivering a written notice of such exercise to Galapagos
(each such notice for any Galapagos Program, an “Option Exercise Notice”).
“Option Exercise Period” means, for each Galapagos Program, the period beginning
on the Completion Date of the first Phase 2 Clinical Trial for a Galapagos
Product in such Galapagos Program (whether or not such Clinical Trial is a
Triggering Clinical Trial) and ending on the earlier to occur of:
(A)    delivery of an Option Exercise Notice by Gilead for such Galapagos
Program or Gilead’ notice that it declines to exercise such Option, and
(B)    11:59 p.m. Pacific time on the later of (1) the […***…] day after the
date on which Galapagos has delivered to Gilead a Qualifying Data Package for
such Galapagos Program and (2) […***…] Business Days after a determination
pursuant to […***…] that a Qualifying Data Package has been delivered;
provided that for any Galapagos Program that is an Acquired Galapagos Program,
clause (B)(1) above shall be the […***…] day after the applicable delivery date;
provided further that the Option Exercise Period for a given Galapagos Program
shall […***…].
(ii)    During the Option Exercise Period for each Galapagos Program, Gilead may
reasonably request additional information with respect to such Galapagos Program
(including in connection with Gilead’s review of the Galapagos Option Schedule
of Exceptions for such Galapagos Program delivered pursuant to Section
8.2(c)(iii)), and to the extent that the information reasonably requested by
Gilead is at such time reasonably available, Galapagos shall make full, accurate
and timely responses to such requests. For clarity, (x) the foregoing sentence
shall have no effect on the duration of the Option Exercise Period and (y)
Galapagos shall not be required, as a result of such an information request by
Gilead pursuant to this Section 8.2(b)(ii), to generate new information or to
conduct any additional Development

activities. If Gilead has not provided an Option Exercise Notice for such
Galapagos Program to Galapagos in accordance with Section 8.2(b)(i) prior to the
end of the Option Exercise Period for such Galapagos Program, then effective
immediately after the end of such Option Exercise Period, such Galapagos Program
shall be an Excluded Program.
(iii)    If Gilead exercises the Option with respect to any Galapagos Program
that is also an Acquired Galapagos Program, then the Parties shall adjust the
terms of this Agreement to the extent necessary to account for any encumbrances
or limitations on such Acquired Galapagos Program that restrict Gilead’s
activities relating to such Acquired Galapagos Program or rights to exploit the
Acquired Galapagos Program pursuant to the terms of this Agreement, including
Gilead’s rights to Commercialize Optioned Products throughout the Gilead
Territory in the Field. With respect to such Acquired Galapagos Program, […***…]

shall […***…].
(v)    “Triggering Clinical Trial” means for each Galapagos Program either:
(A)    the first Phase 2 Clinical Trial that reaches its Completion Date for a
Galapagos Product in such Galapagos Program for a particular indication and that
satisfies each of the following criteria: (1) […***…]; (2) […***…]; and (3)
[…***…]; or
(B)    the first Phase 3 Clinical Trial that reaches its Completion Date for a
Galapagos Product in such Galapagos Program, if such Phase 3 Clinical Trial
reaches its Completion Date prior to any Phase 2 Clinical Trial for such
Galapagos Product in such Galapagos Program that satisfies the criteria in
clause (A) above.
(vi)    Without limitation of the foregoing, any Phase 2 Clinical Trial that
satisfies […***…] will be presumed to be a Triggering Clinical Trial if it is
designed with […***…] and […***…]. For clarity, the foregoing sentence shall not
be interpreted to mean that a Phase 2 Clinical Trial […***…] is presumed to not
be a Triggering Clinical Trial.
(vii)    Notwithstanding anything to the contrary herein, in the event that
Galapagos has Initiated one or more Phase 2 Clinical Trials for the same
indication for a Galapagos Molecule or Galapagos Product in a Galapagos Program
and proposes to Initiate a Phase 3 Clinical Trial prior to the completion of all
such Phase 2 Clinical Trials, then Galapagos’ obligations to deliver a
Qualifying Data Package and Gilead’s right to exercise its Option, in each case,
with respect to such Galapagos Program shall be as set forth in this Section
8.2(b)(vii). Galapagos shall deliver a Qualifying Data Package for the first
such Phase 2 Clinical Trial that constitutes a Triggering Clinical Trial and the
JSC shall make its determination of whether such Phase 2 Clinical Trial
constitutes a Triggering Clinical Trial, in accordance with Section 2.3(d).
Thereafter, within the Option Exercise Period for such Galapagos Program, Gilead
may elect one of the following: (A) deliver an Option Exercise Notice, (B)
notify Galapagos that Gilead does not intend to exercise the Option for such
Galapagos Program or (C) […***…]. If Gilead delivers an Option Exercise Notice
or notifies Galapagos that Gilead declines to exercise such Option, […***…]. If
Gilead notifies Galapagos […***…], then the Option Exercise Period shall end
upon the earliest to occur of (w) […***…], (x) […***…], (y) […***…] and (z)
[…***…]. […***…], Galapagos shall deliver a Qualifying Data Package for each
Phase 2 Clinical Trial that reaches its Completion Date no later than […***…]
days after each such Completion Date, […***…], Gilead may deliver an Option
Exercise Notice or decline to exercise

its Option, in each case, for such Galapagos Program. […***…], Gilead shall be
responsible for […***…] percent […***…] and Galapagos shall be responsible for
[…***…] percent […***…] of the costs of such Phase 3 Clinical Trial as if such
costs were Research and Development Costs under Section 9.9(a) (without regard
to Section 9.9(c)). If Gilead declines to exercise such Option or fails to
timely deliver its Option Exercise Notice, such Galapagos Program shall be an
Excluded Program.
(viii)    Notwithstanding anything to the contrary in this Agreement, with no
further action or consent required on the part of either Party or any Committee,
the ADAMTS-5 Existing Trial shall be deemed the Triggering Clinical Trial for
the ADAMTS-5 Program, and the applicable Option Exercise Period shall commence,
in accordance with this Section 8.2(b), upon the later of the Effective Date and
the Completion Date of such ADAMTS-5 Existing Trial; provided that if another
Clinical Trial meeting the criteria of a Triggering Clinical Trial reaches its
Completion Date with respect to the ADAMTS-5 Program before the ADAMTS-5
Existing Trial reaches its Completion Date, then such other Clinical Trial shall
be treated as the Triggering Clinical Trial with respect to the ADAMTS-5
Program.
(c)    Option Exercise Closing.
(i)    If Gilead delivers an Option Exercise Notice for a Galapagos Program
during the Option Exercise Period for such Galapagos Program in accordance with
Section 8.2(b)(i), subject to Section 8.2(c)(v), such Galapagos Program shall
become an Optioned Program at 12:01 a.m. Pacific Time on the later of the
[…***…] Business Day following (A) Galapagos’ receipt of such Option Exercise
Notice or (B) if any Antitrust Conditions apply to the Option for such Galapagos
Program, the date Gilead notifies Galapagos pursuant to Section 8.2(d) that the
Antitrust Conditions applicable to the Option for such Galapagos Program have
been satisfied (with respect to each such Galapagos Program, an “Option Exercise
Closing”). To the extent permitted by applicable Antitrust Laws, and subject to
Section 8.2(c)(v), if the Antitrust Approvals have been obtained for […***…]
with respect to a Galapagos Program, then (1) an Option Exercise Closing for
such Galapagos Program shall occur for […***…] and each other jurisdiction in
the Territory as to which Antitrust Approval is not required or has been
obtained (such Option Exercise Closing, the “Initial Option Closing”) and (2)
subject to Section 8.2(e), the countries for which an Antitrust Approval is
still required as of the Initial Option Closing (or any subsequent Option
Exercise Closing for such Optioned Program) shall remain part of the Galapagos
Territory unless and until the applicable required Antitrust Approval has been
obtained. Upon each notice of receipt of any such subsequent Antitrust Approval
for such Optioned Program, there shall occur an additional Option Exercise
Closing for such Optioned Program with respect to the applicable jurisdictions.
(ii)    With respect to each Galapagos Program for which Gilead delivers an
Option Exercise Notice during the applicable Option Exercise Period, except as
set forth in the initial Galapagos Option Schedule of Exceptions (which
Galapagos shall deliver together with the Qualifying Data Package) for such
Galapagos Program and subject to Section 8.2(c)(iii), the Galapagos Option
Exercise Representations for such Galapagos Program shall be made (A) subject to
the initial Galapagos Option Schedule of Exceptions, as of the date that the JSC
determines, pursuant to Section 1.1(b)(ii) […***…] that the data package
delivered for such Galapagos Program constitutes a Qualifying Data Package and
(B) subject to the updated Galapagos Option Schedule of Exceptions, as of the
date of the Initial Option Closing for such Galapagos Program (an “Option
Bringdown Date”).
(iii)    With respect to each Galapagos Program for which Gilead delivers an
Option Exercise Notice during the applicable Option Exercise Period, prior to
each applicable Option Exercise Closing for such Galapagos Program, Galapagos
shall promptly notify Gilead in writing if any of the Galapagos Option Exercise
Representations for such Galapagos Program are no longer […***…] and may

(iv)    With respect to each Galapagos Program for which Gilead delivers an
Option Exercise Notice during the applicable Option Exercise Period, prior to
each applicable Option Exercise Closing for such Galapagos Program, Gilead shall
provide Galapagos with an updated list of any Gilead Programs with respect to
such Galapagos Program.
(v)    Notwithstanding anything to the contrary in this Agreement, if at any
time after delivery of an Option Exercise Notice for a Galapagos Program and
before the Initial Option Closing for such Galapagos Program, Galapagos notifies
Gilead, or Gilead otherwise becomes aware, of facts or circumstances that would
cause any of the Galapagos Option Exercise Representations to be […***…] with
respect to such Galapagos Program in a manner that reduces the full scope of
rights that would have been granted to Gilead upon such Option Exercise Closing
absent […***…], then Gilead may […***…]. If, after becoming aware of facts or
circumstances that would cause any of the Galapagos Option Exercise
Representations to be […***…] with respect to such Galapagos Program, Gilead
nevertheless decides not to […***…] for such Galapagos Program, neither
Galapagos nor its Affiliates shall have any liability to Gilead for damages
arising from such […***…] after such notification by Galapagos or awareness of
Gilead; provided that the foregoing shall not restrict, limit or change in any
manner Gilead’s remedies arising from any breach of covenant by Galapagos or any
of its Affiliates that gave rise to such […***…] if Gilead […***…].
(vi)    Notwithstanding anything to the contrary in this Agreement, with no
further action or consent required on the part of either Party or any Committee
pursuant to ARTICLE I, Gilead’s Option with respect to the Autotaxin Program
shall be deemed exercised as of the Effective Date, and the Effective Date shall
be deemed the Initial Option Closing for the Autotaxin Program.
(d)    Antitrust Filing.
(i)    With respect to each Galapagos Program for which Gilead delivers an
Option Exercise Notice during the applicable Option Exercise Period (or prior to
the applicable Option Exercise Period pursuant to Section 8.2(b)(iv)), upon
either Party’s request, the Parties shall work together in good faith to conduct
an analysis of whether any Antitrust Filings are or may be required in
connection with a proposed Option Exercise Closing with respect to such
Galapagos Program.
(ii)    With respect to each Galapagos Program for which Gilead delivers an
Option Exercise Notice during the applicable Option Exercise Period (or prior to
the applicable Option Exercise Period pursuant to Section 8.2(b)(iv)), following
delivery of such Option Exercise Notice, both Parties shall file their
respective Antitrust Filings as promptly as practicable with each applicable
Antitrust Authority pursuant to any applicable Antitrust Laws, and in any event,
with respect to notification and report forms filed with the Federal Trade
Commission (“FTC”) and the Department of Justice (“DOJ”) pursuant to the HSR
Act, if any, the Parties shall make such filings no later than […***…] Business
Days after such delivery of the Option Exercise Notice. Each Party will be
responsible for its own costs and expenses associated with any Antitrust Filing,
but Gilead shall be responsible for payment of all fees to the FTC and DOJ with
respect to Antitrust Filings made pursuant to the HSR Act. The Parties shall
provide each other promptly with information and assistance as may be reasonably
necessary and use reasonable efforts, in each case, to obtain prompt clearance
required under applicable Antitrust Laws for the consummation of the applicable
Option Exercise Closing and the transactions contemplated thereby and shall keep
each other apprised of the status of any communications with, and any inquiries
or requests for additional information

shall be required to consent to the divestiture or other disposition of any of
its or its Affiliates’ assets, consent to any other material structural or
conduct remedy or otherwise restrict or limit its or its Affiliates’ freedom of
action. Each Party shall instruct its counsel to cooperate with the other
Party’s counsel and use reasonable efforts to facilitate and expedite the
identification and resolution of any such issues and, consequently, the
expiration of the applicable HSR Act waiting period and any other applicable
waiting period under Antitrust Laws, including if requested by Gilead, seeking
early termination of any such waiting period. Such reasonable efforts and
cooperation include counsels’ undertaking: (A) to keep each other appropriately
informed of communications from and to personnel of the reviewing Antitrust
Authority; and (B) to confer with each other regarding appropriate contacts with
and response to personnel of the FTC, DOJ or other applicable Antitrust
Authority.
(iii)    Subject to Section 8.2(d)(i), within […***…] Business Days after the

notwithstanding anything to the contrary in Section 8.2(d), if within […***…]
days after the date on which both Parties have made the necessary initial
Antitrust Filings in the applicable country(ies) with respect to such Galapagos
Program, the Initial Option Closing has not occurred, then either Party may
notify the other Party that it is terminating the Option relating to such
Galapagos Program, and unless the non-notifying Party responds within […***…]
Business Days to the notifying Party, providing evidence that it is using
reasonable efforts to secure the necessary Antitrust Approvals in the applicable
jurisdictions (including in response to any additional request from Antitrust
Authorities), such termination of the Option for such Galapagos Program shall
occur at 11:59 p.m. Pacific Time on such […***…] Business Day, at which time
such Galapagos Program shall become an Excluded Program. If the non-notifying
Party responds within such […***…] Business Day period with such evidence, then
either Party may notify the other Party that it is terminating the Option
relating to such Galapagos Program if the Initial Option Closing has not
occurred by 11:59 p.m. Pacific time on the […***…] day after the date on which
both Parties have made such necessary initial Antitrust Filings, and such
termination of the Option for such Galapagos Program shall occur at 12:01 a.m.
Pacific time on […***…].

Party’s request, the Parties shall meet and discuss whether to enter into a
license agreement to obtain rights to such Patent or intellectual property right
for the Exploitation of such Optioned Product in one (1) or more countries in
the Territory and if so, the terms of such license agreement and which Party
should obtain such license agreement. If the Parties agree to enter into such a
license agreement, then the Party that the Parties agree should obtain such
license agreement shall enter into such license agreement on the terms agreed by
the Parties (such license agreement, a “Joint Post-Option In-License”).
(ii)    If the Parties do not agree to obtain a Joint Post-Option In-License
with respect to any Patent or any intellectual property right of a Third Party
in any country, then either Party may enter into a license agreement with such
Third Party for rights under such Patent or intellectual property without the
approval of the other Party (such license agreement, an “Independent Post-Option
In-License”); provided that such Independent Post-Option In-License shall not
impose any obligations on the other Party or preclude the other Party from
negotiating such a license for its Respective Territory. Neither Party may enter
into an Independent Post-Option In-License without first discussing such
in-license agreement with the other Party.
(b)    Responsibility for Payments.
(i)    “Third Party License Payments” means, with respect to a license agreement
with a Third Party for rights under such Third Party’s Patent or other

Third Party License Payments with respect thereto that are: (A) […***…]; (B)
[…***…]; (C) […***…]; or (D) […***…], shall be allocated between the Parties
[…***…]. In determining the reasonable allocation in foregoing clauses (C) and

(v)    Independent Post-Option In-Licenses. With respect to each Independent
Post-Option In-License, subject to (A) Section 9.6(b)(vi) if Gilead or any of
its Affiliates is a party to such Independent Post-Option In-License or (B) the
terms of any Clinical Supply Agreement or Commercial Supply Agreement for which
the Party that is a party to such Independent Post-Option In-License (or one of
its Affiliates) is the supplying the Party, the Party that is a party to such
Independent Post-Option In-License shall be responsible for the Third Party
License Payments thereunder.
(vi)    Gilead Deduction. With respect to any Third Party License Payments for
an Optioned Product in the Gilead Territory (other than any Independent
Post-Option In-License with respect to any improvement or enhancement to such
Optioned Product in the Gilead Territory that is not being Developed or
Commercialized in the Galapagos Territory) for which Gilead is solely
responsible (i.e., for which Galapagos is not also sharing costs pursuant to the
other provisions of this Section 9.6), Gilead shall have the right to offset
[…***…] percent […***…] of such Third Party License Payments against any
royalties or milestone payments owed to Galapagos under this Agreement with
respect to such Optioned Product; provided that any such amount that cannot be
applied to offset amounts due to Galapagos for any calendar quarter may be
carried forward to be applied in the subsequent calendar quarter.
(vii)    Payment Process. With respect to any Third Party License Payments not
shared as Research and Development Costs (and therefore handled through the
process in Section 9.9), on a quarterly basis, the Party initially bearing the
Third Party License Payments shall invoice the other Party for such amount as is
necessary to effectuate the responsibility for Third Party License Payments as
set forth in this Section 9.6. The Party receiving such invoice shall pay it not
later than […***…] days following receipt thereof.
9.7    Following Royalty Term. Upon expiration of the Royalty Term with respect
to an Optioned Product in a country, each Party’s licenses from the other Party
hereunder with respect to such Optioned Product, in such country, shall become
fully paid-up, non-exclusive, perpetual, and irrevocable.
9.8    Veterinary Products. Neither Party, nor any of its Affiliates, shall
Exploit or grant any (sub)licenses to any Third Party to Exploit any Galapagos
Product or Optioned Product for Veterinary Use without the prior written consent
of the other Party. With respect to Veterinary Use, unless set forth in a
separate written agreement between the Parties, no research, development or
commercialization costs and expenses are intended to be shared by the Parties
and no milestones or royalties set forth herein shall apply to the Development
or Commercialization of any Optioned Product for Veterinary Use.

after the applicable Option Exercise Closing with respect to the countries
relating to each Option Exercise Closing, as follows: Gilead shall be
responsible for fifty percent (50%) and Galapagos shall be responsible for fifty
percent (50%). Within […***…] Business Days after the end of each calendar
quarter, each Party shall provide to the other Party a report in reasonable
detail of any Research and Development

43

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

Option, License and Collaboration Agreement

Costs incurred by such Party in such calendar quarter for each Optioned Program,
which may be based on such Party’s good faith estimate. Such Research and
Development Costs so reported shall be used for the calculation of the 50/50
split for the Research and Development Costs (and for clarity, any adjustments
made to such reported amounts shall be taken in the calendar quarter in which
such adjustments are recorded). Within […***…] days following receipt of such
report(s), for all Optioned Programs, the Party that incurred the higher
aggregate Research and Development Costs for the applicable calendar quarter
(across all Optioned Programs), shall invoice the other Party for one-half (1/2)
of the difference between the Parties’ respective aggregate Research and
Development Costs for the applicable calendar quarter (across all Optioned
Programs). The Party receiving such invoice shall pay it not later than […***…]
days following receipt thereof. The Parties will further work together and
reasonably take into account the internal and external reporting requirements
and timelines of the other Party (i) when preparing reports pursuant to this
ARTICLE IX to the other Party, (ii) when aligning the respective R&D Plan and
Budget, Global Commercialization Plan and Budget and Global Manufacturing Plan
and Budget for each Optioned Program and Third Party License Payments and (iii)
during any other planning-related exercise.

out-of-pocket costs and expenses incurred by a Party or any of its Affiliates in
connection with the activities allocated to such Party under the then-current
R&D Plan and Budget exceeds the budget set forth in the then-current R&D Plan
and Budget for such activities during such calendar year, then, if and to the
extent that any such overspend (i) does not exceed […***…] percent […***…] of
the budgeted costs and expenses set forth in the R&D Plan and Budget for such
activities for such calendar year or (ii) is otherwise approved by the Parties,
such approval not to be unreasonably conditioned, withheld or delayed (a
“Permitted R&D Cost Overrun”), then such Permitted R&D Cost Overrun shall be
included in Research and Development Costs and shared by the Parties pursuant to
Section 9.9(a). To the extent that any overspend exceeds […***…] percent […***…]
of the budgeted costs and expenses set forth in the R&D Plan and Budget for such
activities for such calendar year and was not otherwise approved by the Parties
in writing, then such overspend shall not constitute Research and Development
Costs in such calendar year and shall be borne by the Party incurring the same.
The FTE Costs and out-of-pocket costs and expenses incurred by Galapagos or its
Affiliates prior to the date the JSC approves the R&D Plan and Budget for the
Autotaxin Program shall not count towards a Permitted R&D Cost Overrun.
(c)    Post-Approval Commitments and Phase 4 Clinical Trials.
(i)    Mutual Post-Approval Commitments. For each Optioned Program, any Research
and Development Costs incurred by or on behalf of either Party or its Affiliates
in fulfilling any Mutual Post-Approval Commitment (including in conducting any
Requested or Required Phase 4 Clinical Trial to fulfill a Mutual Post-Approval
Commitment) shall be included in the R&D Plan and Budget and the Research and
Development Costs reported to the other Party and split by the Parties in
accordance with Section 9.9(a). For clarity, any dispute regarding Mutual
Post-Approval Commitments shall be subject to the same dispute resolution
process generally applicable to the R&D Plan and Budget for such Optioned
Program to which the Mutual Post-Approval Commitments relate. In the event of a
Mutual Post-Approval Commitment arising from Regulatory Authorities in a non-

activity, unless included in the R&D Plan and Budget or otherwise agreed by the
Parties in writing.
(d)    Phase 3 Triggering Clinical Trial. With respect to each Optioned Program
for which the Triggering Clinical Trial is a Phase 3 Clinical Trial, if such
Triggering Clinical Trial has reached its Completion Date, then Gilead shall pay
to Galapagos an amount equal to the sum of (i) […***…] percent […***…] of the
costs and expenses Gilead would have borne had such Triggering Clinical Trial
been included in an R&D Plan and Budget and (ii) […***…]. Such payment shall be
made to Galapagos within […***…] days after receipt of an invoice with respect
thereto, which invoice must be accompanied by a report in reasonable detail of
such FTE Costs and out-of-pocket costs and expenses.
(e)    Delayed Initial Option Closing. If the Initial Option Closing for a
Galapagos Program has not occurred within […***…] days after the date on which
both Parties have made the necessary initial Antitrust Filings in the applicable
country(ies) as set forth in Section 8.2(e), and such Initial Option Closing
subsequently occurs, then Gilead shall be responsible for […***…] percent
[…***…] of the Research and Development Costs incurred for such Optioned Program
beginning on the […***…] day after the date on which both Parties have made the
necessary initial Antitrust Filings in the applicable country(ies) in accordance

Affiliates after the applicable Option Exercise Closing with respect to the
countries relating to each Option Exercise Closing, as follows: Gilead shall be
responsible for fifty percent (50%) and Galapagos shall be responsible for fifty
percent (50%). Within […***…] Business Days after the end of each calendar
quarter, each Party shall provide to the other Party a report in reasonable
detail of any Shared Commercialization Costs incurred by such Party in such
calendar quarter for each Optioned Program, which report may be based on such
Party’s good faith estimate. Such Shared Commercialization Costs so reported
shall be used for the calculation of the 50/50 split for the Shared
Commercialization Costs. Within […***…] days following receipt of such
report(s), for all Optioned Programs, the Party that incurred the higher
aggregate Shared Commercialization Costs for the applicable period (across all
Optioned Programs), shall invoice the other Party for one-half (1/2) of the
difference between the Parties’ respective aggregate Shared Commercialization
Costs for the applicable period (across all Optioned Programs). The Party
receiving such invoice shall pay it not later than […***…] days following
receipt thereof.
(b)    If in any calendar year the Shared Commercialization Costs incurred by a
Party exceed the budget set forth in the then-current Global Commercialization
Plan and Budget for the activities allocated to it thereunder during such
calendar year, then, if and to the extent that any such overspend (i) does not
exceed […***…] percent […***…] of the budgeted costs and expenses set forth in
the Global Commercialization Plan and Budget for such activities for such
calendar year, or (ii) is otherwise approved by the Parties, such approval not
to be unreasonably conditioned, withheld or delayed (a “Permitted
Commercialization Overrun”), then such Permitted Commercialization Overrun shall
be included in Shared Commercialization Costs and shared by the Parties pursuant
to Section 9.10(a). To the extent that any overspend exceeds […***…] percent
[…***…] of the budgeted costs and expenses set forth in the Global
Commercialization Plan and Budget for such activities in such calendar year and
was not otherwise approved by the Parties, then such overspend shall not
constitute Shared Commercialization Costs in such calendar year and shall be
borne by the Party incurring the same.

reasonable efforts to mitigate or reduce Tax withholding or similar obligations
in respect of royalties, milestone payments, and other payments made between the
Parties under this Agreement. Without limiting the generality of the foregoing,
each Party shall provide the other with any Tax forms and other information that
may be reasonably necessary in order to eliminate or reduce withholding based on
an applicable treaty. Each Party shall provide the other with reasonable
assistance to enable the recovery, as permitted by Applicable Law, of

receipt of a valid Tax invoice issued in accordance with Applicable Law.
(d)    Payment of Tax. To the extent Gilead is required by Applicable Law to
deduct or withhold Taxes on any payment to Galapagos, Gilead shall pay the
amounts of such Taxes to the proper Governmental Authority in a timely manner;
provided that Gilead must provide Galapagos with at least […***…] days’ notice
of the applicability of any withholding Tax with respect to such payment, and
Gilead and Galapagos shall […***…] work together during such […***…] day period
to eliminate or reduce such withholding. Any amount withheld or deducted by
Gilead pursuant to this provision shall be treated as having been paid to
Galapagos for purposes of this Agreement. Gilead must promptly (within […***…]
days of payment) transmit to Galapagos an official Tax certificate or other
evidence of any withholding sufficient to enable Galapagos to claim available
credits for withholding Tax deducted or withheld by Gilead.
(e)    No Partnership.  Galapagos and Gilead intend that this Agreement will not

or such Affiliate pursuant to this Agreement or of any payments made, or
required to be made, by or to the audited Party or such Affiliate to the other
pursuant to this Agreement. Any such auditor shall not disclose the audited
Party’s or its Affiliates’ confidential information to the auditing Party, but

audit and if such a discrepancy was uncovered, the amount and direction of it.
Any amounts shown to be owed but unpaid, or overpaid and in need of
reimbursement, shall be paid or refunded (as the case may be) within […***…]
days after the auditor’s report, plus interest (as set forth in Section 9.14)

resolved in accordance with ARTICLE XV, any remaining disputed portion shall be
paid within […***…] days after resolution of the dispute, and interest shall not
accrue with respect to the disputed portion during the period of time the

any Program Infringement of any Galapagos Patent, Joint Collaboration Patent, or
Gilead Collaboration Patent based on competition with, or a Generic Product of,
an Optioned Molecule or Optioned Product, Gilead shall have the first right and
authority, but not the obligation, to bring suit or other action to abate any
Program Infringement of any Galapagos Patents, Joint Collaboration Patents and
Gilead Collaboration Patent; provided that, Gilead shall (1) provide at least
[…***…] days’ written notice to Galapagos of its intent to bring such suit or

Gilead Patent, Galapagos shall have the second right and authority, but not the
obligation, to bring such suit or other action.
(e)    Other Infringement.
(i)    Galapagos Patents and Joint Collaboration Patents. With respect to any
infringement, threatened infringement or alleged infringement of any Galapagos
Patent or Joint Collaboration Patent that is not a Program Infringement,

to bring such suit or other action, (B) consider, reasonably and in good faith,
all input received from Galapagos with respect thereto and (C) conduct such suit
or other action in a manner that Galapagos reasonably believes to be in the best

action under this Section 10.4, the Party that is not bringing such suit or
other action (“Non-Enforcing Party”) shall cooperate fully as may be reasonably
requested by the Party bringing such suit or other action (“Enforcing Party”),
upon reasonable notice, to maintain such suit or other action, by executing and
making available such documents as the Enforcing Party may reasonably request,
and by performing all other acts which are or may become reasonably necessary to
vest in the Enforcing Party the right to institute any such suit or other
action, including by being joined to such action if so requested and by using
commercially reasonable efforts to obtain any necessary joinder or cooperation
in any such suit or other action from any applicable Third Parties. The
Enforcing Party shall keep the Non-Enforcing Party regularly informed of the
status and progress of such efforts, and shall reasonably consider the
Non-Enforcing Party’s comments on any such efforts.

and Galapagos is the Trademark Licensee Party, Commercialize any applicable
Optioned Products in such Optioned Program in the countries in the Galapagos
Territory (as it exists immediately after the applicable Option Exercise
Closing) and (B) if Galapagos is the Trademark Owner Party and Gilead is the
Trademark Licensee Party, Commercialize any applicable Optioned Products in such
Optioned Program in the countries in the Gilead Territory (as it exists
immediately after the applicable Option Exercise Closing). At the request of the
Trademark Licensee Party for any Global Optioned Product Trademarks, the Parties
shall promptly enter into a separate trademark license agreement consistent with
the licenses described in this Section 10.9(c)(i).
(ii)    Certain Conditions. With respect to each Global Optioned Product
Trademark, the Trademark Licensee Party shall not, and shall not permit its

is confusingly similar to, misleading or deceptive with respect to or that
dilutes any (or any part) of such Global Optioned Product Trademark, or (B) do
any act that endangers, destroys, or similarly affects, in any material respect,
the value of the goodwill pertaining to such Global Optioned Product Trademark.

written consent, use any Trademarks or house marks of the other Party (including
the other Party’s corporate name), or marks confusingly similar thereto, in
connection with such Party’s marketing or promotion of Optioned Products under
this Agreement, except as may be expressly authorized in the Global
Commercialization Plan and Budget (which, for clarity, shall include
authorization related to the Global Optioned Product Trademark).
10.10    Confirmatory Licenses. Each Party shall, if so requested by the other
Party, promptly enter into confirmatory license agreements, in a form consistent

(b)    Assignment of Rights. Each Person who has or has had any rights in or to
any Existing Galapagos Patents or any material Galapagos Know-How has assigned
and has executed an agreement assigning its entire right, title and interest in

Galapagos’ and its Affiliates’ Knowledge, no breach of such confidentiality has
been committed by any Third Party.
(j)    No Proceedings.
(i)    No claim or litigation has been brought or threatened in writing by any
Person against Galapagos or any of its Affiliates alleging, and Galapagos has no
Knowledge of any reasonable basis for any such claim or allegation, whether or

its Pre-Program Activities or Galapagos Programs.
(k)    No Misappropriation. The conception and reduction to practice of any
inventions and the use or development of any other Information within the
Galapagos IP (i) owned by Galapagos have not constituted or involved the
misappropriation of trade secrets or other rights or property of any Third Party
and (ii) in-licensed by Galapagos, to Galapagos’ Knowledge, have not constituted
or involved the misappropriation of trade secrets or other rights or property of
any Third Party; provided, however, that the foregoing clauses (i) and (ii)
shall not constitute a representation or warranty of non-infringement of a Third
Party’s intellectual property rights.
(l)    Full Disclosure. Galapagos has provided or made available to Gilead all
material adverse information with respect to the safety and efficacy of the
Galapagos Molecules or Galapagos Products relating to the ADAMTS-5 Program and

12.3    Indemnification Procedures. All indemnification claims with respect to a
Gilead Indemnitee or Galapagos Indemnitee shall be made solely by Gilead or
Galapagos, as applicable. The Party claiming indemnity under this ARTICLE XII
(the “Indemnified Party”) shall give written notice to the Party from which
indemnity is being sought (the “Indemnifying Party”) promptly after learning of
the Third Party Claim for which indemnity is being sought. The Indemnifying
Party’s obligations to defend, indemnify, and hold harmless pursuant to
Section 12.1 or 12.2, as applicable, shall be reduced to the extent the
Indemnified Party’s delay in providing notification pursuant to the previous
sentence results in prejudice to the Indemnifying Party. At its option, the
Indemnifying Party may assume the defense of any Third Party Claim for which
indemnity is being sought by giving written notice to the Indemnified Party
within […***…] days after receipt of the notice of the Third Party Claim. The
assumption of defense of a Third Party Claim shall not be construed as an
acknowledgment that the Indemnifying Party is liable to indemnify any
Indemnified Party in respect of the Third Party Claim, nor shall it constitute a
waiver by the Indemnifying Party of any defenses it may assert against the
Indemnified Party’s claim for indemnification. The Indemnified Party shall
provide the Indemnifying Party with reasonable assistance, at the Indemnifying
Party’s expense, in connection with the defense of any Third Party Claim. The
Indemnified Party may participate in and monitor such defense with counsel of
its own choosing at its sole expense, subject to the Indemnifying Party’s right
to assume and conduct the defense of the Third Party Claim with counsel of its
choice. If the Indemnifying Party does not assume and conduct the defense of a
Third Party Claim as provided above, then (a) the Indemnified Party may defend
against such Third Party Claim (and the Indemnified Party need not consult with
the Indemnifying Party in

70

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

Option, License and Collaboration Agreement

connection therewith), and (b) the Indemnified Party reserves any rights it may
have under this ARTICLE XII to obtain indemnification from the Indemnifying
Party with respect to such Third Party Claim. The Indemnifying Party shall not
settle any Third Party Claim without the prior written consent of the
Indemnified Party, not to be unreasonably withheld, conditioned or delayed,
unless the settlement involves only the payment of money for which the
Indemnifying Party is responsible. The Indemnified Party shall not settle any
Third Party Claim for which it has or will exercise its right under this ARTICLE
XII to obtain indemnification from the Indemnifying Party without the prior
written consent of the Indemnifying Party, which consent shall not be
unreasonably withheld, conditioned or delayed.
12.4    Shared Development Losses.
(a)    The Parties shall share equally any Losses incurred by any Gilead
Indemnitee or Galapagos Indemnitee (collectively, “Party Indemnitees”) to the
extent resulting from Third Party Claims against any such Party Indemnitee that
arise from or are based on the performance of any activities under an R&D Plan
and Budget with respect to which Research and Development Costs are shared
equally by the Parties, to the extent (i) not arising from or based on the
events described in clauses (a), (b), (c), (e), (f), (g), and (h) of Section
12.1 or clauses (a), (b), (c), (e), (f), and (g) of Section 12.2 or (ii) not
otherwise provided in Section 10.6 (any such Losses, “Shared Development Losses”
and any such Third Party Claims, “Shared Development Claims”). If either Party
receives notice of any Shared Development Claim, such Party shall inform the
other Party in writing as soon as reasonably practicable, and the Parties shall
discuss a strategy for defending such Shared Development Claim. For clarity,
this Section 12.4 is not intended, and shall not be construed, to alter either
Party’s liability under Section 12.1(d) or Section 12.2(d) (as applicable) for
any Losses that arise from or are based on any commercially sold Optioned
Product.
(b)    At its option, Gilead may assume the defense of any Shared Development
Claim by giving written notice to Galapagos within […***…] days after the notice
of the Shared Development Claim. If Gilead does not assume and conduct the
defense of a Shared Development Claim as provided in the preceding sentence,
then Galapagos may defend against such Shared Development Claim. The
non-defending Party shall provide the defending Party with reasonable assistance
in connection with the defense of any Shared Development Claim. The
non-defending Party may participate in and monitor such defense with counsel of
its own choosing. subject to the defending Party’s right to assume and conduct
the defense of the Shared Development Claim with counsel of its choice. Neither
Party shall settle any Shared Development Claim without the prior written
consent of the other Party, not to be unreasonably withheld, conditioned or
delayed.

Program(s) or Optioned Program(s) to which such material breach relates;
provided that (1) the materiality of any breach by Gilead shall be measured in
relation to the entire Gilead Territory for the applicable Galapagos Program or
Optioned Program (and any material breach with respect to the United States
shall be deemed a material breach with respect to the entire territory) and (2)
any such proposed termination shall not become effective if Gilead cures the
breach specified in such notice during the applicable notice period set forth in
clause (A) or clause (B) (or in the case of clause (B), if not curable within
such […***…]-day period, then for up to a maximum additional […***…]-day period
but only so long as, during such additional […***…]-day period, Gilead is using
reasonable efforts to do so). Notwithstanding the foregoing, in the event that
the termination for material breach is solely with respect to one or more
countries other than the United States but not all countries, then for such
Galapagos Program or Optioned Program, as the case may be, the Gilead Territory
shall no longer include such country or countries and in lieu of termination of
this Agreement under this Section 14.4(a)(i), such country or countries shall
become part of the Galapagos Territory and a transition analogous to the
transition described in Section 14.7 shall be conducted. If there is a basis to
terminate this Agreement with respect to an Optioned Product in the United
States pursuant to this Section 14.4(a)(i), then Galapagos shall have the right
to terminate this Agreement in its entirety with respect to such Optioned
Program pursuant to this Section 14.4(a)(i).
(ii)    Rights of Gilead for Galapagos’ Breach. Subject to Section 14.4(b) and
Section 14.4(c), if Galapagos materially breaches its obligations under this
Agreement with respect to any Galapagos Program or Optioned Program, then Gilead
shall have the right to terminate this Agreement with respect to such Galapagos
Program (which termination shall be with respect to all Galapagos Molecules and
Galapagos Products included in such Galapagos Program) or Optioned Program
(which termination shall be with respect to all Optioned Molecules and Optioned
Products included in such Optioned Program) by providing (A) in the case of a
failure by Galapagos to make any payment due hereunder, […***…] days’ or (B) in
the case of any other material breach by Galapagos, […***…] days’, in each case
((A) and (B)), prior written notice to Galapagos identifying such material
breach in reasonable detail and the Galapagos Program(s) or Optioned Program(s)
to which such material breach relates; provided that any such proposed
termination shall not become effective if Galapagos cures the breach specified
in such notice during the applicable notice period set forth in clause (A) or
clause (B) (or in the case of clause (B), if not curable within such […***…]-day
period, then for up to a maximum additional […***…]-day period but only so long
as, during such additional […***…]-day period, Galapagos is using reasonable
efforts to do so). Without limitation to the foregoing, in lieu of Gilead’s
right to terminate this Agreement pursuant to this Section 14.4(a)(ii) with
respect to any Galapagos Program or Optioned Program, Gilead shall have the
right to elect (as its sole remedy for such breach), in its written notice to
Galapagos identifying the applicable material breach, to (1) maintain the
effectiveness of this Agreement with respect to such Galapagos Program or
Optioned Program and (2) reduce by […***…] percent […***…] any amounts payable
to Galapagos under ARTICLE IX with respect to such Galapagos Program (if and
when it becomes an Optioned Program) or Optioned Program (in each case,
including with respect to all Galapagos Molecules, Galapagos Products, Optioned
Molecules and Optioned Products included in such Galapagos Program or Optioned
Program, as the case may be); provided that (x) any such proposed reduction
shall not become effective if Galapagos cures the breach specified in such
notice during the applicable notice period or during an additional […***…]-day
period thereafter and (y) such reduction shall terminate and Gilead shall again
be responsible for the full amounts payable to Galapagos under ARTICLE IX at
such time as […***…].

(B)    With respect to each Gilead Clinical Trial for which Galapagos elects to

the Parties’ obligations with respect to unauthorized sales, and setting forth
other coordination obligations. If, despite such efforts, the Parties are unable
to agree upon the terms and conditions of any Transition Agreement within

Party may refer the dispute for resolution by arbitration in accordance with
Section 15.2(d).
(A)    Transition Assistance. The Transition Agreement shall require Gilead,
[…***…], to disclose and provide to Galapagos (1) […***…] and that is necessary

such disclosure and provision. The foregoing obligation described in clause (2)
shall include assigning to Galapagos, upon request of Galapagos, any agreements
between Gilead or any of its Affiliates and Third Party suppliers or vendors to
the extent such agreements solely and specifically relate to the supply or sale
of the applicable Reversion Product(s) with respect to the applicable Terminated
Region(s). If any such agreement is not assignable to Galapagos (whether by such
agreement’s terms or because such agreement does not solely and specifically
relate to the supply or sale of the applicable Reversion Product(s) with respect
to the applicable Terminated Region(s)) but is otherwise reasonably necessary or
useful for Galapagos to Develop, Manufacture or Commercialize any such Reversion
Product(s) with respect to the applicable Terminated Region(s), then Gilead
shall reasonably cooperate with Galapagos in Galapagos’ efforts to obtain from
such Third Party the assignment of such agreement or of that portion of such
agreement that solely and specifically relates to the supply or sale of such
Reversion Product(s) with respect to the applicable Terminated Region(s). With
respect to any applicable Reversion Product(s) and the applicable Terminated
Region(s), unless and until any such agreements are assigned to Galapagos
pursuant to the preceding sentences, or if Gilead Manufactures such Reversion
Product(s) itself (and thus there is no agreement to assign), the Transition
Agreement shall require Gilead to supply bulk finished quantities of such
Reversion Product(s) to Galapagos with respect to the applicable Terminated
Region(s) for a reasonable period following the effective date of termination
(not to exceed […***…] months) to enable Galapagos to establish an alternate,
validated source of supply for such Reversion Product(s). The cost to Galapagos
for supply of any such Reversion Product shall be […***…].
(B)    Regulatory Materials. The Transition Agreement shall require Gilead to
transfer and assign to Galapagos […***…], that relate to any applicable
Reversion Product(s) in or for the benefit of the applicable Terminated
Region(s). The Transition Agreement shall contain terms governing the
coordination of any ongoing regulatory responsibilities with respect to such
Reversion Product(s) that are required under Applicable Law to be conducted by
Gilead with respect to the applicable Terminated Region(s).
(v)    Third Party Agreements. To the extent that any payments would be owed by
Gilead or any of its Affiliates to any Third Party (including royalties,
milestones and other amounts) under any Third Party agreements that are
applicable to the grant to Galapagos of any (sub)license, right of reference or
other right provided in this Section 14.7 or any Transition Agreement, or that
are applicable to the exercise by Galapagos or any of its Affiliates or
Sublicensees of any sublicense or other right with respect thereto, Gilead shall
notify Galapagos of the existence and anticipated amounts of such payments and
Galapagos shall have the right either to decline such (sub)license, right of
reference or other right provided in this Section 14.7 or such Transition
Agreement or to accept the same, in which case Galapagos shall (A) comply with
any obligation under any such Third Party agreement that apply to Galapagos
(provided that Gilead has notified Galapagos of such obligation in writing) and
(B) be responsible for any such payments.
(vi)    Remaining Inventories.
(A)    Gilead shall be entitled, during the […***…] days following termination
of this Agreement with respect to any Terminated Product(s) and Terminated
Region(s), to finish any work-in-progress and to sell in the applicable

of this Agreement with respect to any Terminated Product(s) and Terminated
Region(s), Galapagos shall have the right, upon written notice to Gilead, to
purchase from Gilead any or all of the inventory of Reversion Product(s) held by
Gilead with respect to any such Terminated Region(s) as of the date of such
notice solely for distribution in the applicable Terminated Region(s) and other
countries in the Galapagos Territory and not for distribution in the remainder
of the Gilead Territory (which inventory of Reversion Product(s) is not
committed to be supplied to any Third Party as of such date) at a price equal to
[…***…].
14.8    Other Remedies. Termination or expiration of this Agreement for any
reason shall not release either Party from any liability or obligation that
already has accrued prior to such expiration or termination, nor affect the
survival of any provision hereof to the extent it is expressly stated to survive
such termination. Termination or expiration of this Agreement for any reason
shall not constitute a waiver or release of, or otherwise be deemed to prejudice
or adversely affect, any rights, remedies or claims, whether for damages or
otherwise, that a Party may have hereunder or that may arise out of or in
connection with such termination or expiration.
14.9    Rights in Bankruptcy. All rights and licenses granted under or pursuant
to this Agreement by Galapagos and Gilead are, and shall otherwise be deemed to
be, for purposes of Section 365(n) of the U.S. Bankruptcy Code, licenses of
right to “intellectual property” as defined under Section 101 of the U.S.
Bankruptcy Code. The Parties agree that each Party, as licensee of certain
rights under this Agreement, shall retain and may fully exercise all of its
rights and elections under the U.S. Bankruptcy Code. The Parties further agree
that, in the event of the commencement of a bankruptcy proceeding by or against
a Party (such Party, the “Bankrupt Party”) under the U.S. Bankruptcy Code, the
other Party shall be entitled to a complete duplicate of (or complete access to,
as appropriate) any intellectual property licensed to such other Party pursuant
to the terms of this Agreement and all embodiments of such intellectual
property, which, if not already in such other Party’s possession, shall be
promptly delivered to it (a) upon any such commencement of a bankruptcy
proceeding upon such other Party’s written request therefor, unless the Bankrupt
Party elects to continue to perform all of its obligations under this Agreement
or (b) if not delivered under clause (a), following the rejection of this
Agreement by the Bankrupt Party upon written request therefor by the other
Party. In the case of an Insolvency that is governed by non-U.S. bankruptcy law,
the Parties agree that, to the extent not prohibited by the applicable
Insolvency law, the non-Bankrupt Party will be entitled to the same rights and
protections afforded by the U.S. Bankruptcy Code, including survival of the
licenses granted hereunder even if the Bankrupt Party revokes or terminates this
Agreement and a copy of the embodiments of such intellectual property, without
conditions other than payment of any royalties due hereunder.
14.10    Survival. Termination or expiration of this Agreement shall not affect
rights or obligations of the Parties under this Agreement that have accrued
prior to the date of termination or expiration of this Agreement. 
Notwithstanding anything to the contrary, the following provisions shall survive
and apply after expiration or termination of this Agreement in its entirety:
ARTICLE XII, ARTICLE XIII, ARTICLE XV, ARTICLE XVII, and Sections 2.6(b), 2.6(d)
(other than the last sentence), 4.2(b) (subject to Section 14.7(c) and the terms
of any Transition Agreement, if applicable), 4.3, 7.4 (subject to Section
14.7(c) and the terms of any Transition Agreement, if applicable), 9.5, 9.6(b)
(expiration only), 9.7 (expiration only), 9.12, 9.13, 9.14, 9.15, 9.16, 9.17,
10.1 (subject to Section 14.7(c) and the terms of any Transition Agreement, if
applicable), 11.4, 14.7, 14.8, 14.9 and 14.10, and any applicable definitions of
any capitalized terms, including those set forth in Appendix A; provided,
however, that in case of termination pursuant to Section 14.2, only the
provisions referenced in Section 16.5 and any applicable definitions of any
capitalized terms, including those set forth in Appendix A, shall survive and
apply.  In addition, except in case of termination pursuant to Section 14.2, the
other applicable provisions of ARTICLE IX shall survive and apply to the extent
required

84

Option, License and Collaboration Agreement

to make final reimbursements, reconciliations or other payments incurred or
accrued prior to the date of termination or expiration.  For any surviving
provisions requiring action or decision by a Committee or an Executive Officer,
each Party will appoint representatives to act as its Committee members or
Executive Officer, as applicable.  All provisions not surviving in accordance
with the foregoing shall terminate upon expiration or termination of this
Agreement and be of no further force and effect. If this Agreement is terminated
with respect to one or more Terminated Regions but not in its entirety, then
following such termination the foregoing provisions of this Agreement shall
remain in effect with respect to the Terminated Regions (to the extent they
would survive and apply in the event the Agreement expires or is terminated in
its entirety), and all provisions not surviving in accordance with the foregoing
shall terminate upon termination of this Agreement with respect to the
applicable Terminated Region(s) and be of no further force and effect (and for
the avoidance of doubt all provisions of this Agreement shall remain in effect
with respect to any countries that are not terminated).

15.1    Disputes.
(a)    Generally. It is the objective of the Parties to establish procedures to
facilitate the resolution of disputes arising under this Agreement in an
expedient manner by mutual cooperation and without resort to litigation.
(b)    Non-Committee Disputes. In the event of any dispute that may arise
between the Parties out of or in relation to or in connection with this
Agreement (“Dispute”) that does not arise from a matter within the
decision-making jurisdiction of a Committee (a “Non-Committee Dispute”),
including any alleged failure to perform, or breach, of this Agreement, or any
issue relating to the interpretation or application of this Agreement, either
Party may refer such Non-Committee Dispute to (i) with respect to any
Non-Committee Dispute regarding Development or Commercialization, the Parties’
applicable Subject Matter Experts and (ii) with respect to any other
Non-Committee Dispute, the Executive Officers of the Parties. Following any such
referral to Subject Matter Experts, such Subject Matter Experts shall attempt to
reach consensus on such Non-Committee Dispute during a period of […***…]
Business Days, and any final decision agreed to in writing by the Subject Matter
Experts with respect to such Non-Committee Dispute shall be binding on the
Parties. If such Subject Matter Experts cannot reach consensus on such
Non-Committee Dispute within such period, then either Party may refer such
Non-Committee Dispute to the Executive Officers of the Parties for resolution.
Following referral to the Executive Officers (either after referral to Subject
Matter Experts or as an initial matter, as applicable), the Executive Officers
shall attempt to reach consensus on such Non-Committee Dispute during a period
of […***…] Business Days thereafter, and any final decision agreed to in writing
by the Executive Officers with respect to such Non-Committee Dispute shall be
binding on the Parties. If the Executive Officers cannot reach consensus on such
Non-Committee Dispute within such period, then either Party may then invoke the
applicable provisions of Section 15.2(a), Section 15.2(d) or Section 15.7, as
applicable; provided, however, that with respect to any dispute that relates to
Prosecution of the Galapagos Patents, such provisions shall not be invoked and
rather be decided as specified in ARTICLE X.
(c)    Committee Disputes. In the event of a Dispute that arises from a
Committee and is within the decision-making jurisdiction of such Committee (a
“Committee Dispute”), the Parties shall first attempt to resolve such Committee
Dispute pursuant to ARTICLE I, including Section 1.5. If the Committee Dispute
is not resolved pursuant to ARTICLE I, then such Committee Dispute shall be
resolved in accordance with Section 1.5 […***…].

any conflict between this Section 15.2(b) and Section 15.2(c). Any arbitration
shall be conducted in accordance with the applicable rules of the International
Chamber of Commerce (“ICC Rules”) by three (3) arbitrators. Each Party will
select one arbitrator, and the two (2) arbitrators so selected by the Parties
shall select the third arbitrator. The arbitrators shall have significant

Parties shall have the right to be represented by counsel. Any judgment or award
rendered by the arbitrators shall be final and binding on the Parties, and shall
be governed by the terms and conditions hereof, including the limitation on
damages set forth in Section 12.5. The Parties agree that such a judgment or
award may be enforced in any court of competent jurisdiction. The statute of
limitations of the State of New York applicable to the commencement of a lawsuit

arbitrators shall determine the allocation of costs and expenses and attorneys’
fees in the arbitration to be borne by each Party. All proceedings and decisions
of the arbitrators shall be deemed Confidential Information of both of the
Parties, and shall be subject to ARTICLE XIII. The arbitrators shall issue
appropriate protective orders to safeguard each Party’s Confidential
Information. Except as required by Applicable Law, neither Party shall make (or
instruct the arbitrators to make) any public announcement with respect to the
proceedings or decision of the arbitrators without prior written consent of the
other Party. The existence of any Dispute submitted to arbitration, and the
award, shall

connection with the enforcement of such award or as otherwise required by
Applicable Law.

(i)    Within […***…] Business Days after appointment of the third arbitrator
pursuant to Section 15.2(c), each Party shall deliver to the arbitrators and to

“Proposal”), as applicable, and a memorandum in support thereof. Within […***…]
Business Days after receipt of the other Party’s Proposal and memorandum, each
Party may submit to the arbitrators (with a copy to the other Party) a response
to the other Party’s Proposal. Except as directed by the arbitrators and in any
event with both Parties present or participating, neither Party may have any
other communications (either written or oral) with the arbitrators other than
for the sole purpose of engaging the arbitrators.
(ii)    Within […***…] days after the receipt of the Proposals and memoranda
from both Parties, the arbitrators shall select the Proposal provided by one
Party (without modification) that the arbitrators believe is […***…]. The
arbitrators must select, as the only method to resolve such a Dispute, the
Proposal of one Party and, absent agreement by the Parties, may not combine
elements of both of the Parties’ Proposals or terms or award any other relief or
take any other action. The selection by the arbitrators of the applicable
Proposal shall be binding and conclusive on the Parties.
(iii)    With respect to any Dispute regarding […***…], the arbitrators shall

(e)    Survivability. Any obligation to arbitrate under this Agreement shall
remain in effect and be enforceable after termination of this Agreement for any

15.3    Governing Law. This Agreement shall be governed by and construed under

15.4    Award. Any award to be paid by one Party to the other Party as
determined by the arbitrators pursuant to Section 15.2 shall be promptly paid in
Dollars free of any Tax, deduction or offset; and any costs, expenses, fees or
Taxes incident to enforcing the award shall, to the maximum extent permitted by
Applicable Law, be charged against the Party resisting enforcement. Each Party
agrees to abide by the award rendered in any arbitration conducted pursuant to
this ARTICLE XV, and agrees that, subject to the U.S. Federal Arbitration Act, 9
U.S.C. §§ 1-16, judgment may be entered upon the final award in the U.S. Federal
District Court for the Southern District of New York and that other courts may
award full faith and credit to such judgment in order to enforce such award.
15.5    Injunctive Relief. Nothing in this ARTICLE XV will preclude either Party
from seeking equitable relief or interim or provisional relief from a court of
competent jurisdiction, including a temporary restraining order, preliminary
injunction or other interim equitable relief, concerning a Dispute either prior
to or during any arbitration if necessary to protect the interests of such Party
or to preserve the status quo pending the arbitration proceeding. Therefore, in
addition to its rights and remedies otherwise available at law, including the
recovery of damages for breach of this Agreement, upon an adequate showing of
material breach, and

Galapagos Option Exercise Representations

The Galapagos Program that is the subject of the Option Exercise Notice to which
these Option Exercise Representations and the corresponding Galapagos Option
Schedule of Exceptions relate is referred to as the “Subject Program.” Except as
set forth in such Galapagos Option Schedule of Exceptions, Galapagos hereby
represents and warrants and, with respect to Sections 4 and 8 below, covenants
to Gilead as of the applicable Option Exercise Closing, except as set forth in
the corresponding Galapagos Option Schedule of Exceptions, as follows with
respect to the Subject Program:
1.
No Debarment. Neither Galapagos nor any of its Affiliates is debarred, has been
convicted, or is subject to debarment or conviction pursuant to Section 306 of
the FD&C Act. Galapagos has not used in connection with any activity in its
business, any employee, agent or independent contractor who has been debarred by
any Regulatory Authority, or, to the best of Galapagos’ knowledge, is the
subject of debarment proceedings by a Regulatory Authority or has been convicted
pursuant to Section 306 of the FD&C Act. Galapagos shall promptly notify Gilead
of any debarment or debarment proceeding that could have an impact on the use of
the results of any Clinical Trials relating to the Subject Program.

2.
Title; Encumbrances. Galapagos or one of its Affiliates solely owns or
exclusively licenses and Controls the Existing Galapagos Patents and other
Galapagos IP relating to the Subject Program, provided, however, that the
foregoing shall not constitute a representation or warranty of non-infringement
of a Third Party’s intellectual property rights. Galapagos or one of its
Affiliates has the right to grant the licenses for the Subject Program to Gilead
as purported to be granted pursuant to this Option Exercise Closing. Neither
Galapagos nor any of its Affiliates has entered into any agreement (other than
agreements with subcontractors) granting any right, interest or claim in or to,
any Existing Galapagos Patents or Galapagos Know-How relating to the Subject
Program to any Third Party that would conflict with the rights and licenses to
Gilead as purported to be granted pursuant to this Option Exercise.

3.
Assignment of Rights. Each Person who has or has had any rights in or to any
Existing Galapagos Patents or any material Galapagos Know-How relating to the
Subject Program has assigned and has executed an agreement assigning its entire
right, title and interest in and to such Existing Galapagos Patents and
Galapagos Know-How relating to the Subject Program to Galapagos or one of its
Affiliates. To Galapagos’ Knowledge, no current officer, employee, agent, or
consultant of Galapagos or any of its Affiliates is in violation of any term of
any assignment or other agreement regarding the protection of Patents or other
intellectual property or proprietary information of Galapagos or such Affiliate
relating to the Subject Program or of any employment contract relating to the
relationship of any such Person with Galapagos.

A-3

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

4.
Patents. All Existing Galapagos Patents for the Subject Program are identified
on Schedule 4. All Existing Galapagos Patents for the Subject Program are
subsisting and are being diligently prosecuted in the patent offices indicated
on Schedule 4 in accordance with Applicable Law and to Galapagos’ Knowledge are
not invalid or unenforceable in whole or in part. All applicable fees with
respect thereto have been timely paid or will be timely paid (taking account of
any permitted extensions). The Existing Galapagos Patents on Schedule 4
represent all Patents within Galapagos’ or its Affiliates’ ownership or control
(by license or otherwise) that Galapagos reasonably believes include claims
covering the making, using or composition of matter of the Galapagos Molecules
or Galapagos Products, or the Exploitation of any such Galapagos Molecule or
Galapagos Product, in each case, in the Subject Program. To the extent required,
Galapagos or one of its Affiliates has properly recorded in the relevant U.S.
and foreign patent offices the assignments, or other necessary documents,
supporting its legal title to the Existing Galapagos Patents for the Subject
Program on Schedule 4. Galapagos and its Affiliates have presented, or will
present prior to the pertinent patent office deadlines, all relevant references,
documents or information of which they and the inventors are aware to the
relevant patent examiner at the pertinent patent office, in connection with the
prosecution of the pending patent applications included in the Existing
Galapagos Patents for the Subject Program.

5.
No Infringement. To Galapagos’ Knowledge, no Person is infringing or threatening
to infringe or misappropriating or threatening to misappropriate any Existing
Galapagos Patents or any Galapagos Know-How or Regulatory Documentation relating
to the Subject Program. To Galapagos’ Knowledge, there are no activities by
Third Parties that would constitute infringement or misappropriation of the
Galapagos IP relating to the Subject Program (in the case of pending claims,
evaluating them as if issued).

6.
No Conflicts. The consummation of this Option Exercise Closing does not, and the
consummation of the transactions contemplated by this Option Exercise Closing
will not, (i) except for the rights granted to Gilead in this Option Exercise,
result in the creation of any encumbrance on any of the material properties or
assets relating to the Subject Program, or (ii) conflict with, or result in any
violation of or default under (with or without notice or lapse of time, or
both), or give rise to a right of termination, cancellation or acceleration of
any obligation or loss of any benefit under, or require any consent, approval or
waiver from any Person pursuant to (A) any provision of the organizational or
governing documents of Galapagos, in each case as amended to date, or (B) any
material agreement applicable to Galapagos’ or any of its Affiliates’ material
properties or assets relating to the Subject Program.

7.
In-Licenses and Restrictions on Business Activities. None of the Existing
Galapagos Patents for the Subject Program licensed hereunder by Galapagos to
Gilead are owned or controlled in whole or in part by any Third Party. There is
no agreement, judgment, injunction, order or decree of a Governmental Authority
with respect to the Subject Program binding upon Galapagos or any of its
Affiliates that has or would reasonably be expected to have, whether before or
after the Option Exercise Closing, the effect of

A-4

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

materials have been legally assigned or licensed to Galapagos or such Affiliate
to the extent necessary to provide Gilead with the rights granted to it
hereunder, and all rights in all inventions and discoveries made, developed, or
conceived by any employee or independent contractor of Galapagos or any of its
Affiliates during the course of their employment (or other retention) by
Galapagos or such Affiliate, and relating to or included in the Galapagos
Know-How or that are the subject of one or more Existing Galapagos Patents, in
each case relating to the Subject Program, have been or will be assigned in
writing to Galapagos or such Affiliate to the extent necessary to provide Gilead
with the rights granted to it hereunder.

9.

(including under any Patents and other intellectual property rights) to use all
Information and all other materials (including any formulations and
manufacturing processes and procedures) developed or delivered by any Third
Party under any agreements between Galapagos or one of its Affiliates and any
such Third Party with respect to the Subject Program to the extent necessary to
provide Gilead with the rights granted to it hereunder, and Galapagos or one of
its Affiliates has the rights under each such agreement to transfer such
Information or other materials to Gilead and its designees and to grant Gilead
the right to use such Information or other materials in the Development or
Commercialization of the Galapagos Molecules or Galapagos Products in the
Subject Program as required to enable Gilead to Exploit the Galapagos Molecules
and the Galapagos Products in the Subject Program in the Gilead Territory.

Know-How the confidentiality of which is material to the Exploitation of any
Galapagos Molecule or Galapagos Product in the Subject Program, such portions of
the Galapagos Know-How have been kept confidential or have been disclosed to
Third Parties only under terms of confidentiality or if published or otherwise
publicly disclosed, were published or publicly disclosed in a manner that would
not reasonably be expected to adversely impact the patentability of such
Galapagos Know-How relating to the Subject Program. To Galapagos’ and its
Affiliates’ Knowledge, no breach of such confidentiality relating to the Subject
Program has been committed by any Third Party.

11.
No Proceedings.

a.
No claim or litigation has been brought or threatened in writing by any Person
against Galapagos or any of its Affiliates alleging, and Galapagos has no
Knowledge of any reasonable basis for any such claim or allegation, whether or
