Exhibit 99.1

GILEAD AND GALAPAGOS COMPLETE CLOSING OF THEIR TRANSFORMATIVE RESEARCH AND DEVELOPMENT COLLABORATION

Foster City, Calif. and Mechelen, Belgium; 23 August 2019; 22.01 CET; regulated information – Gilead Sciences, Inc. (NASDAQ: GILD) and Galapagos NV (Euronext & NASDAQ: GLPG) today announced the closing of the global research and development collaboration agreement signed on 14 July 2019.

This agreement has received clearance from the U.S. Federal Trade Commission under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 and merger control approval from the Austrian Federal Competition Authority.

Under the terms of the agreement, the closing of this transaction triggers an upfront license fee payment of $3.95 billion by Gilead to Galapagos. In addition, Gilead has made an equity investment in Galapagos of approximately $1.1 billion (or approximately €960 million) by subscribing for new shares at a price of €140.59 per share, including issuance premium. As a result, Gilead now owns 13,589,686 ordinary shares of Galapagos, representing approximately 22 percent of the currently outstanding share capital of Galapagos.

“We are excited to close this unique agreement, which will generate both long-term strategic value and mutual, immediate benefits,” said Daniel O’Day, Chairman and Chief Executive Officer of Gilead. “The collaboration reflects Gilead’s intent to grow our innovation network through diverse and creative partnerships.”

“This agreement is about maximizing innovation based on developing new mode of action medicines. With the capital provided by Gilead, we aim to progress innovation to patients,” said Onno van de Stolpe, Chief Executive Officer of Galapagos.

In accordance with Belgian transparency legislation¹, Galapagos notes that its total share capital currently amounts to €333,479,569.76; the total number of securities conferring voting rights is 61,652,086, which is also the total number of voting rights (the “denominator”), and all securities conferring voting rights and all voting rights are of the same category. The total number of rights (warrants) to subscribe to not yet issued securities conferring voting rights is 5,958,292, which equals the total number of voting rights that may result from the exercise of these warrants. Galapagos does not have any convertible bonds or shares without voting rights outstanding.

Galapagos Forward-Looking Statements

This release may contain forward-looking statements with respect to Galapagos, including statements regarding Galapagos’ strategic ambitions, the implementation of the global collaboration agreement, and the amount and timing of any payments by Gilead to Galapagos. Galapagos cautions the reader that forward-looking statements are not guarantees of future performance. Forward-looking statements involve known and unknown risks, uncertainties and other factors which might cause the actual results, financial condition and liquidity, performance or achievements of Galapagos, or industry results, to be materially different from any historic or future results, financial conditions and liquidity, performance or achievements expressed or implied by such forward-looking statements. In addition, even if Galapagos’ results, performance, financial condition and liquidity, and the development of the industry in which it operates are consistent with such forward-looking statements, they may not be predictive of results or developments in future periods. Among the factors that may result in differences are the inherent uncertainties associated with competitive developments, clinical trial and product development activities and regulatory approval requirements (including that data from the ongoing and planned clinical research programs may not support registration or further development of its candidate products due to safety, efficacy or other reasons),

Galapagos’ reliance on collaborations with third parties (including its collaboration partner Gilead), and estimating the commercial potential of its candidate products. A further list and description of these risks, uncertainties and other risks can be found in Galapagos’ Securities and Exchange Commission (SEC) filings and reports, including in Galapagos’ most recent annual report on Form 20-F filed with the SEC and subsequent filings and reports filed by Galapagos with the SEC. Given these uncertainties, the reader is advised not to place any undue reliance on such forward-looking statements. These forward-looking statements speak only as of the date of publication of this document. Galapagos expressly disclaims any obligation to update any such forward-looking statements in this document to reflect any change in its expectations with regard thereto or any change in events, conditions or circumstances on which any such statement is based or that may affect the likelihood that actual results will differ from those set forth in the forward-looking statements, unless specifically required by law or regulation.

Gilead Forward-Looking Statements

This press release includes forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995, related to Gilead, Galapagos and the global research and development collaboration agreement that are subject to risks, uncertainties and other factors. All statements other than statements of historical fact are statements that could be deemed forward-looking statements, including all statements regarding the intent, belief or current expectation of the companies and members of their senior management team. Forward-looking statements include, without limitation, the risk that Gilead may not realize any benefits from the global collaboration agreement; its potential effects on Gilead’s revenues and earnings; Gilead may fail to discover, develop and commercialize any of Galapagos’ pipeline products under the agreement; the filing of the new drug applications for approval of filgotinib in the currently anticipated timeframe; approval of filgotinib by regulatory authorities, including any approvals, if granted, may have significant limitations on its use; the anticipated timing of clinical data of Galapagos’ pipeline products; the possibility of unfavorable results from these clinical trials; and the accuracy of any assumptions underlying any of the foregoing. Investors are cautioned that any such forward-looking statements are not guarantees of future performance and involve risks and uncertainties and are cautioned not to place undue reliance on these forward-looking statements. Actual results may differ materially from those currently anticipated due to a number of risks and uncertainties. Risks and uncertainties that could cause the actual results to differ from expectations contemplated by forward-looking statements include: the occurrence of any event, change or other circumstance that could give rise to the termination of the collaboration agreement; the effects of the transaction on relationships with employees, customers, other business partners or governmental entities; transaction costs; the risk Galapagos’ stockholders do not approve Gilead’s board nominees or issuance of the warrants, as the case may be. These and other risks are described in detail in Gilead’s Quarterly Report on Form 10-Q for the quarter ended June 30, 2019, as filed with the U.S. Securities and Exchange Commission. All forward-looking statements are based on information currently available to Gilead, and Gilead assumes no obligation to update any such forward-looking statements.

Option, License and Collaboration Agreement

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.

30

Option, License and Collaboration Agreement

(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 be responsible for any […***…].

(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.

31

Option, License and Collaboration Agreement

(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”).

(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.

If the Parties do not reach agreement on the terms of any such agreement, such terms shall be determined pursuant to Section 15.1(b) and 15.2(d). If Galapagos does not make such request within […***…] days of such notice, then Gilead shall have the right to proceed with such license, sale or other grant or transfer.

8.13 Existing Galapagos Third Party Obligations.

(a) For so long and to the extent applicable to this Agreement, (i) Gilead shall provide Galapagos such assistance and take such actions as necessary for Galapagos to be in compliance with the provisions set forth on the Existing Galapagos Third Party Obligation Schedule, as such provisions exist as of the Execution Date and have been fully disclosed to Gilead, and (ii) upon Galapagos’ written request, Gilead shall use commercially reasonable efforts to provide Galapagos such assistance and take such actions as necessary for Galapagos to be in compliance with the provisions of the Existing Galapagos Third Party Agreements.

In partial consideration of the license granted by Galapagos under Section 8.3, during the applicable Royalty Term only, and on an Optioned Product-by-Optioned Product basis, Gilead shall pay to Galapagos non-refundable royalties in each calendar year on the amount of aggregate Net Sales of the applicable Optioned Product in the Gilead Territory (other than in Access Territory where such Optioned Product is available on an Affordable Basis), as calculated by multiplying the applicable royalty rates set forth below by the corresponding amount of incremental Net Sales of such Optioned Product in such calendar year.

For example, if the aggregate Net Sales of all Optioned Products in a given Optioned Program in a particular calendar year is $[…***…], the amount of royalties payable under this Section 9.4(a) shall be as follows: […***…]% of $[…***…] plus […***…]% of $[…***…] = $[…***…].

From and after the expiration of the Royalty Term for an Optioned Product in a country, (i) Gilead shall no longer have any obligation to pay any royalty on Net Sales of such Optioned Product in such country and (ii) Net Sales of such Optioned Product in such country shall be excluded for purposes of determining the royalty tiers set forth above.

(ii) Upon […***…], the royalty rates applicable to Net Sales of Optioned Products in such country shall be […***…] of the rates set forth in Section 9.4(a).

For clarity, only one (1) reduction under either of the foregoing clauses (i) or (ii) will apply and the maximum reduction in the royalty rates set forth in Section 9.4(a) is […***…].

9.6 Payments to Third Parties.

(a) Negotiation of Post-Option In-Licenses.

(i) For each Optioned Program, if either Party desires to obtain a license under any Patent or any intellectual property right of a Third Party in any country to Exploit an applicable Optioned Product in such country, then, at such 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.

In determining the reasonable allocation in foregoing clauses (C) and (D), the Parties shall take into account […***…].

(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.

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 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.

(b) Permitted R&D Cost Overrun. If in any calendar year the FTE Costs and 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- Major Market, the Parties may discuss in good faith the impact of performing such Mutual Post-Approval Commitments on activities relating to the applicable Optioned Program in their Respective Territories.

44

Option, License and Collaboration Agreement

(ii) Other Post-Approval Commitments and Phase 4 Clinical Trials. For each Optioned Program, any Research and Development Costs incurred by or on behalf of either Party or its Affiliates in (A) fulfilling any post-approval commitment other than a Mutual Post-Approval Commitment or (B) conducting any Phase 4 Clinical Trial that is not conducted to fulfill a Mutual Post-Approval Commitment, in each case ((A) and (B)), shall be excluded from the Research and Development Costs reported to the other Party pursuant to Section 9.9(a) and shall be borne by the Party conducting such 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 with Section 9.9(a). Galapagos shall include any such costs in the invoices provided pursuant to Section 9.9(a).

9.10 Shared Commercialization Costs.

(a) For each Optioned Program, the Parties shall share the Shared Commercialization Costs incurred by or on behalf of either Party or its 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.

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 Patent 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 Shared Patent Costs so reported shall be used for the calculation of the […***…] the Shared Patent Costs. Within […***…] days following receipt of such report(s), the Party that incurred the higher aggregate Shared Patent Costs for the applicable period shall invoice the other Party for […***…] of the difference between the Parties’ respective aggregate Shared Patent Costs for the applicable period. The Party receiving such invoice shall pay it not later than […***…] days following receipt thereof.

(b) If Gilead requests that Galapagos incur Patent Costs with respect to a Galapagos Program and Galapagos agrees to incur such Patent Costs, then Section 9.11(a) shall apply to such Patent Costs as if such Patent Costs were Shared Patent Costs relating to an Optioned Program.

9.12 Taxes.

(a) Taxes on Income. Each Party shall be solely responsible for the payment of all Taxes imposed on its share of income arising directly or indirectly from the collaborative efforts of the Parties under this Agreement.

(b) Tax Cooperation. The Parties shall cooperate with one another and use 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.

(a) Title; Encumbrances. Galapagos or one of its Affiliates solely owns or exclusively licenses and Controls the Existing Galapagos Patents relating to any Galapagos 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 to Gilead as purported to be granted pursuant to this Agreement. 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 to any Third Party that would conflict with the rights and licenses to Gilead as purported to be granted pursuant to this Agreement.

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 and to such Existing Galapagos Patents and Galapagos Know-How 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 or of any employment contract relating to the relationship of any such Person with Galapagos.

(d) 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.

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.

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.

(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.

NEITHER PARTY SHALL BE LIABLE TO THE OTHER PARTY FOR ANY SPECIAL, CONSEQUENTIAL, INCIDENTAL, PUNITIVE, OR INDIRECT DAMAGES, INCLUDING FOR LOSS OF PROFITS SUFFERED BY THE OTHER PARTY, ARISING FROM OR RELATING TO ANY BREACH OF THIS AGREEMENT OR ANY TORT CLAIMS ARISING HEREUNDER, REGARDLESS OF ANY NOTICE OF THE POSSIBILITY OF SUCH DAMAGES. NOTWITHSTANDING THE FOREGOING, NOTHING IN THIS SECTION 12.5 IS INTENDED, OR SHALL BE CONSTRUED, TO LIMIT OR RESTRICT (A) THE RIGHTS OR OBLIGATIONS OF EITHER PARTY UNDER SECTIONS 12.1, 12.2 OR 12.4; (B) LIABILITY FOR A PARTY’S BREACH OF ITS CONFIDENTIALITY OBLIGATIONS UNDER ARTICLE XIII; OR (C) LIABILITY IN THE CASE OF A PARTY’S FRAUD, GROSS NEGLIGENCE OR INTENTIONAL MISCONDUCT.

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.

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.

The 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 statute of limitations of the State of New York applicable to the commencement of a lawsuit shall apply to the commencement of arbitration under this ARTICLE XV. The 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 be kept in confidence by the Parties and the arbitrators, except as required in connection with the enforcement of such award or as otherwise required by Applicable Law.

(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 […***…].

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.

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 without further proof of irreparable harm other than this acknowledgement, such non-breaching Party shall be entitled to seek (a) immediate equitable relief, specifically including both interim and permanent restraining orders and injunctions, and (b) such other and further equitable relief as the court may deem proper under the circumstances.
