Regulatory Authority pursuant to Applicable Law in accordance with Article 8.

3.3.3 Meetings with Regulatory Authorities.
Yakult shall provide GPC Biotech with prior written notice of any Major Meeting promptly after Yakult receives notice of the scheduling of such Major Meeting, when practicable, within such time period as may be necessary in order to give GPC Biotech

previously been achieved.

6.2 Transfer Charges.Subject to Section 6.3, during the term of this Agreement, in consideration
for the rights granted by GPC Biotech hereunder and the Licensed Product supplied by or on behalf of GPC Biotech under the Supply Agreement, Yakult shall calculate, for each full or partial Calendar Year, an amount (each, a Transfer
Charge) based, in part, on aggregate Net Sales of the Licensed Product in Japan during such Calendar Year as set forth in Sections 6.2.1 through 6.2.5 below. For clarity, in any Calendar Year (a) the portion of the total Transfer
Charge for that Calendar Year that is attributable to the cost of supply of Licensed Product under the Supply Agreement shall be the aggregate Supply Price (as defined in the Supply Agreement) for all Licensed Product sold in Japan in that Calendar
Year, and (b) the remaining portion of the aggregate Transfer Charge for that Calendar Year shall be deemed the royalty payment (the Royalty Payment), payable to GPC Biotech. For that portion of aggregate Net Sales of the
Licensed Product in Japan in such Calendar Year that:

6.2.1is less than Six Billion Japanese Yen (JPY 6,000,000,000), the Transfer
Charge shall be equal to (a) if the Satraplatin Price is less than the CDDP-based Price, [***] percent ([***]%), (b) if the Satraplatin Price is greater than or equal to the CDDP-based Price, but less than the Docetaxel-based
Price, [***] percent ([***]%), (c) if the Satraplatin Price is greater than or equal to the Docetaxel-based Price, but less than twice the CDDP-based Price, [***] percent ([***]%) or (d) if the Satraplatin Price
is greater than or equal to twice the CDDP-based Price, [***] percent ([***]%), in each case ((a) through (d)), of such Net Sales;

6.2.2equals or exceeds Six Billion Japanese Yen (JPY 6,000,000,000), but is less than Twelve Billion Japanese Yen (JPY 12,000,000,000), the Transfer Charge shall be equal

[***] percent ([***]%) or (d) if the Satraplatin Price is greater than or equal to twice the CDDP-based Price, [***] percent ([***]%), in each case ((a) through (d)), of such Net Sales;

6.2.3equals or exceeds Twelve Billion Japanese Yen (JPY 12,000,000,000), but is less than Eighteen Billion Japanese Yen (JPY 18,000,000,000), the
Transfer Charge shall be equal to (a) if the Satraplatin Price is less than the CDDP-based Price, [***] percent ([***]%), (b) if the Satraplatin Price is greater than or equal to the CDDP-based Price, but less than the
Docetaxel-based Price, [***] percent ([***]%), (c) if the Satraplatin Price is greater than or equal to the Docetaxel-based Price, but less than twice the CDDP-based Price, [***] percent ([***]%) or (d) if the
Satraplatin Price is greater than or equal to twice the CDDP-based Price, [***] percent ([***]%), in each case ((a) through (d)), of such Net Sales;

6.2.4equals or exceeds Eighteen Billion Japanese Yen (JPY 18,000,000,000), but is less than Twenty-Four Billion Japanese Yen (JPY 24,000,000,000), the Transfer Charge shall be equal to (a) if the
Satraplatin Price is less than the CDDP-based Price, [***] percent ([***]%), (b) if the Satraplatin Price is greater than or equal to the CDDP-based Price, but less than the Docetaxel-based Price, [***] percent
([***]%), (c) if the Satraplatin Price is greater than or equal to the Docetaxel-based Price, but less than twice the CDDP-based Price, [***] percent ([***]%) or (d) if the Satraplatin Price is greater than or equal to
twice the CDDP-based Price, [***] percent ([***]%), in each case ((a) through (d)), of such Net Sales; and

6.2.5equals or exceeds Twenty-Four Billion Japanese Yen (JPY 24,000,000,000), the Transfer Charge shall be equal to (a) if the Satraplatin Price is less than the CDDP-based Price [***] percent ([***]%), (b) if the Satraplatin
Price is greater than or equal to the CDDP-based Price, but less than the Docetaxel-based Price, [***] percent ([***]%), (c) if the Satraplatin Price is greater than or equal to the Docetaxel-based Price, but less than twice the
CDDP-based Price, [***] percent ([***]%) or (d) if the Satraplatin Price is greater than or equal to twice the CDDP-based Price, [***] percent ([***]%), in each case ((a) through (d)), of such Net Sales.

Notwithstanding the foregoing, except as otherwise expressly provided in Section 7.4.1, and subject to Section 6.3, in no event shall the Royalty Payment
(i.e., the Transfer Charge for such Calendar Quarter, less the Supply Price for all Licensed Product sold in Japan in such Calendar Quarter) payable in any Calendar Quarter fall below [***] Percent ([***]%) of Net Sales for such
Calendar Quarter (such minimum amount, the Royalty Payment Floor). If, in any Calendar Quarter, the Royalty Payment is lower than the Royalty Payment Floor, then Yakult shall pay to GPC Biotech (in accordance with

Yakult each, an initial pursuing Party). Upon reasonable request by the initial pursuing Party, the other Party shall give the initial pursuing Party all reasonable information and assistance, including producing documents from
such other Partys files or producing files for inspection as requested by the initial pursuing Party and allowing access to such other Partys files and documents and to such other Partys personnel who may have possession of
relevant information and, if necessary for the initial pursuing Party to prosecute any legal action, joining in the legal action as a party at its own expense.

(a)If GPC Biotech is the initial pursuing Party and fails within ninety (90) days following notice of such infringement, as provided in the first sentence of this Section 7.3.1, or earlier notifies
Yakult in writing of its intent not to take commercially appropriate steps to stop any infringement of any GPC Biotech Patent, Joint Patent, or Product Trademark in Japan that is likely or could reasonably be expected to have a material adverse
effect on the sale of the Licensed Product in Japan, and GPC Biotech has not granted the infringing Third Party rights and licenses to continue its otherwise infringing activities, then, unless GPC Biotech provides Yakult with a commercially
reasonable basis in writing for not taking such steps, as between the Parties, Yakult shall have the right, but not the obligation, to do so at its sole cost and expense in Japan; provided, however, that if GPC Biotech has commenced
negotiations with an alleged infringer for discontinuance of such infringement within such ninety (90)-day period, GPC Biotech shall have an additional ninety (90) days to conclude its negotiations before Yakult may bring suit for such
infringement.

(b)If Yakult is the initial pursuing Party and fails within ninety (90) days following notice of such
infringement, as provided in the first sentence of this Section 7.3.1, or earlier notifies GPC Biotech in writing of its intent not to take commercially appropriate steps to stop any infringement of any Yakult Patent that is likely or could
reasonably be expected to have a material adverse effect on the sale of the Licensed Product in the Territory, and Yakult has not granted the infringing Third Party rights and licenses to continue its otherwise infringing activities, then, unless
Yakult provides GPC Biotech with a commercially reasonable basis in writing for not taking such steps, as between the Parties, GPC Biotech shall have the right, but not the obligation, to do so at its sole cost and expense in the Territory;
provided, however, that if Yakult has commenced negotiations with an alleged infringer for discontinuance of such infringement within such ninety (90)-day period, Yakult shall have an additional ninety (90) days to conclude its
negotiations before GPC Biotech may bring suit for such infringement.

Upon reasonable request by such other Party, the initial pursuing Party shall give such other Party all reasonable
information and assistance in connection with such suit for infringement.

7.3.2 Generic Competition.Notwithstanding the foregoing,
if either Party (a) reasonably believes that a Third Party may be filing or preparing or seeking to file a generic or abridged Drug Approval Application that refers to or relies on Regulatory Documentation submitted by either Party to any
Regulatory Authority whether or not such a filing may be in violation of any Regulatory Exclusivity Period or infringe the GPC Biotech Patents, the Yakult Patents or the Joint Patents or (b) receives any notice regarding the GPC Biotech
Patents, Joint Patents or Yakult Patents claiming that any such Patents are invalid or unenforceable or claiming that any such Patents will not be infringed by the Manufacture, use, marketing or sale of a Third Partys product, it shall notify
the other Party in writing and provide the other Party a copy of any such notice within ten (10) days of receipt and the Parties rights and obligations with respect to any legal action as a result of such notice shall be as set forth in
Section 7.3.1; provided, however, that if the enforcing Party elects not to bring suit against the Third Party providing such notice within thirty (30) days of receipt of such notice with respect to any GPC Biotech Patent,
Yakult Patent or Joint Patent in Japan, then the other Party shall have the right, but shall not the obligation, to bring suit against such Third Party and to join the enforcing Party as a Party plaintiff if necessary to bring such a suit, in which
event the other Party shall hold the enforcing Party harmless from and against any and all costs and expenses of such litigation, including reasonable attorneys fees and expenses.

7.3.3 Costs and Expenses.Each Party shall bear its own costs and expenses relating to any enforcement action pursuant to Section 7.3.1 or
7.3.2. Any damages or other amounts collected shall be used to reimburse the Parties for their costs and expenses in making such recovery (which amounts shall be allocated pro rata if insufficient to cover the totality of such expenses), with any
remainder being retained by the Party that pursued such enforcement action; provided, however, with respect to any amount received by the enforcing Party that relates to infringement of a Patent in Japan, such remainder shall be shared
equally by the Parties.

7.4 Potential Third Party Rights.

7.4.1 Third Party Licenses.If the Development or Commercialization of the Licensed Product in accordance with the terms and conditions of this
Agreement, by Yakult or its Affiliates infringes or misappropriates any Patent or any Intellectual Property Right of a Third Party in Japan, such that Yakult or any of its Affiliates cannot, in the reasonable opinion of Yakult as advised by
competent patent counsel, Develop or Commercialize the Licensed Product in Japan without infringing the Patent or Intellectual Property Right of such Third Party, then, as between the Parties, Yakult shall be solely responsible for securing any
Third Party licenses to such Patent or Intellectual Property Right in Japan that it deems necessary or desirable in connection with the Development or Commercialization of the Licensed Product in Japan by Yakult or any of its Affiliates, and for any
associated license fees, milestones, royalties or other payments due to such Third Party (Third Party Payments); provided that GPC Biotech shall be solely responsible for all license fees, milestones and royalties due to
Spectrum pursuant to the

7.4.2 Invalidity or Unenforceability Defenses or Actions.

(a)In the event that a Third Party asserts, as a defense or as a counterclaim in any infringement action under Section 7.3.1, that any Product Trademark, GPC Biotech Patent, Yakult Patent or Joint Patent
is invalid or unenforceable, then the Party pursuing such infringement action shall promptly give written notice to the other Party. With respect to the Product Trademarks, GPC Biotech Patents and the Joint Patents, as between the Parties, GPC
Biotech shall have the first right, but not the obligation, through counsel of its choosing, to respond to such defense or defend against such counterclaim (as applicable) and, if Yakult is pursuing the applicable infringement action under
Section 7.3.1, Yakult shall allow GPC Biotech to control such response or defense (as applicable). If GPC Biotech determines not to respond to such defense or defend against such counterclaim (as applicable) with respect to the Product
Trademarks, GPC Biotech Patents or Joint Patents in Japan, then Yakult shall, at its sole cost and expense, have the right to respond to such defense or defend against such counterclaim (as applicable); provided, however, that to the
extent that ceasing to defend, settling or otherwise compromising such defense or counterclaim is likely or could reasonably be expected to have a material impact in the GPC Biotech Territory, Yakult shall obtain the written consent of GPC Biotech
prior to ceasing to defend, settling or otherwise compromising such defense or counterclaim, such consent not to be unreasonably withheld or delayed. With respect to the Yakult Patents, as between the Parties, Yakult shall have the first right, but
not the obligation, through counsel of its choosing, to respond to such defense or defend against such counterclaim (as applicable) and, if GPC Biotech is pursuing the applicable infringement action under Section 7.3.1, GPC Biotech shall allow
Yakult to control such response or defense (as applicable). If Yakult determines not to respond to such defense or defend against such counterclaim (as applicable) with respect to the Yakult Patents in the Territory, then GPC Biotech shall, at its
sole cost and expense, have the right to respond to such defense or defend against such counterclaim (as applicable); provided, however, that to the extent that ceasing to defend, settling or otherwise compromising such defense or
counterclaim is likely or could reasonably be expected to have a material impact in Japan, GPC Biotech shall obtain the written consent of Yakult prior to ceasing to defend, settling or otherwise compromising such defense or counterclaim, such
consent not to be unreasonably withheld or delayed. Any costs and expenses with respect to such response or defense against such counterclaim shall be borne by the Party controlling such response or defense.

(b)Similarly, if a Third Party asserts, in a declaratory judgment action or similar action or claim filed by such Third Party, that any Product
Trademark, GPC Biotech Patent, Yakult Patent or Joint Patent is invalid or unenforceable, then the Party first becoming aware of such action or claim shall promptly give written notice to the other Party. As between the Parties, with respect to
Product Trademarks, GPC Biotech Patents and Joint Patents, GPC

Biotech shall have the first right, but not the obligation, through counsel of its choosing, to defend against such action or claim. If GPC Biotech
determines not to assume such defense with respect to the Product Trademarks, GPC Biotech Patents or Joint Patents in Japan, then Yakult shall, at its sole cost and expense, have the right to defend against such action or claim; provided,
however, that to the extent that ceasing to defend, settling or otherwise compromising such action or claim is likely or could reasonably be expected to have a material impact in the GPC Biotech Territory, Yakult shall obtain the written
consent of GPC Biotech prior to ceasing to defend, settling or otherwise compromising such action or claim, such consent not to be unreasonably withheld or delayed. As between the Parties, with respect to Yakult Patents, Yakult shall have the first
right, but not the obligation, through counsel of its choosing, to defend against such action or claim. If Yakult determines not to assume such defense with respect to the Yakult Patents in the Territory, then GPC Biotech shall, at its sole cost and
expense, have the right to defend against such action or claim; provided, however, that to the extent that ceasing to defend, settling or otherwise compromising such action or claim is likely or could reasonably be expected to have a
material impact in Japan, GPC Biotech shall obtain the written consent of Yakult prior to ceasing to defend, settling or otherwise compromising such action or claim, such consent not to be unreasonably withheld or delayed. Any costs and expenses
with respect to such defense shall be borne by the Party defending against such action or claim.

(c)Each Party shall provide to
the other Party all reasonable assistance requested by the other Party in connection with any action, claim or suit under this Section 7.4.2, including allowing such other Party access to the assisting Partys files and documents and to
the assisting Partys personnel who may have possession of relevant information. In particular, the assisting Party shall promptly make available to the other Party, free of charge, all information in its possession or control that it is aware
will be reasonably necessary to assist the other Party in responding to any such action, claim or suit.

7.4.3 Third Party Litigation.In the event of any actual or threatened suit against Yakult or its Affiliates alleging that the Development or Commercialization of the Licensed Product in Japan infringes the Patent or Intellectual Property Rights of any Third Party, Yakult
shall, as between the Parties, assume direction and control of the defense of claims arising therefrom (including the right to settle such claims at its sole discretion); provided, however, that Yakult shall obtain the written consent
of GPC Biotech prior to ceasing to defend, settling or otherwise compromising such claims where such settlement or compromise would have an adverse affect on the validity or enforceability of any Patents and Intellectual Property Rights of GPC
Biotech (including the Joint Intellectual Property Rights) or where such consent would otherwise be required pursuant to Section 12.4.2, such consent not to be unreasonably withheld or delayed. Each Party shall provide the other Party with
copies of any notices it receives from Third Parties relating to any patent nullity actions, declaratory judgment actions and any alleged infringement or misappropriation of the Intellectual Property Rights of a Third Party by the Development,

Product in the Field in Japan as currently conducted by GPC Biotech or as contemplated by this Agreement does or would infringe or result in the misappropriation of any Patent or other Intellectual Property Rights of any Third Party.

11.3.4To GPC Biotechs Knowledge, the GPC Biotech Patents in Japan have been procured or are being procured from the respective Patent
Offices in accordance with Applicable Law.

11.3.5GPC Biotech has no Knowledge of any actual infringement or threatened
infringement of the GPC Biotech Patents or GPC Biotech Know-How in Japan by any Person.

11.3.6GPC Biotech has no Knowledge of any
claim or litigation that has been brought or threatened in writing by any Person alleging that (a) the GPC Biotech Patents or the GPC Biotech Know-How are invalid or unenforceable in Japan or (b) the Development and Commercialization of
the Licensed Product in the Field in Japan as contemplated by this Agreement infringes any Patent or other Intellectual Property Right Controlled by any Third Party.

11.3.7GPC Biotech has not, up through and including the Effective Date, Knowingly withheld (except as previously stated by GPC Biotech to Yakult) any material information, including reports of Adverse Event
Experiences and warning letters from Regulatory Authorities, in GPC Biotechs possession from Yakult in response to Yakults reasonable inquiries in connection with its due diligence relating to the Licensed Compound, Licensed Product,
this Agreement and the underlying transaction. To GPC Biotechs Knowledge, the clinical data related to Licensed Product in the Field that GPC Biotech has provided to Yakult prior to the Effective Date was, when access was provided to Yakult,
up-to-date and accurate in all material respects and GPC Biotech has provided Yakult with any material updates to such clinical data that have occurred since the time such access was provided to Yakult.

11.4 The Spectrum Agreement and J-M License Agreement.

11.4.1 Representations and Warranties of GPC Biotech Concerning the Spectrum Agreement and the J-M License Agreement. GPC Biotech represents and warrants to Yakult that, as of the Effective Date:

(a)The Spectrum Agreement is in full force and effect and has not been modified or amended, except that no representation or warranty relating to
the Spectrum Agreement is made with respect to Spectrum or matters solely within the control or direction of Spectrum that are not known to GPC Biotech;

(b)To the best of GPC Biotechs Knowledge, the J-M License Agreement is in full force and
effect and has not been modified or amended in any manner that would conflict with the terms of this Agreement, except that no representation or warranty relating to the J-M License Agreement is made with respect to J-M or Spectrum or matters solely
within the control or direction of J-M and Spectrum;

(c)To the best of GPC Biotechs Knowledge, GPC Biotech is not in
default with respect to a material obligation under the Spectrum Agreement;

(d)Spectrum filed a demand for arbitration and
statement of claims with the American Arbitration Association on December 12, 2006, in which Spectrum asserts that (i) GPC Biotech has breached the Spectrum Agreement, (ii) Spectrum has a basis for termination of the Spectrum
Agreement, and (iii) termination of the Spectrum Agreement would result in transfer to Spectrum of all GPC Biotechs rights and duties under the Pharmion Agreement;

(e)Section 15.7 of the Spectrum Agreement requires that upon any termination of the Spectrum Agreement, all sublicenses granted by GPC
Biotech, which would include this Agreement with Yakult, shall be automatically assigned to Neotherapeutics Inc. (now Spectrum), which shall thereafter receive all benefits and have all obligations under the sublicenses as in the place and stead of
GPC Biotech; and

(f)GPC Biotech has not waived or allowed to lapse any of its rights under the Spectrum Agreement, and no such
rights have lapsed or otherwise expired or been terminated.

11.4.2 GPC Biotechs Obligations Concerning the Spectrum
Agreement. GPC Biotech agrees that during the term of this Agreement:

(a)GPC Biotech shall use Commercially Reasonable Efforts
to fulfill its obligations under the Spectrum Agreement to the extent that failure to do so would adversely affect Yakult or its rights hereunder;

(b)Without prior notice to Yakult and Yakults prior written consent, GPC Biotech shall not enter into any subsequent agreement with Spectrum that modifies or amends the Spectrum Agreement in any way that would reasonably be
expected to adversely affect Yakults rights or economic interest under this Agreement, including by increasing Yakults obligation under this Agreement for any payment and royalty obligations, or any additional payment or royalty not
already undertaken. GPC Biotech shall provide Yakult with a copy for Yakults prior review of all such proposed modifications to or amendments of the Spectrum Agreement and all other material modifications to or amendments of the Spectrum
Agreement, regardless of whether Yakults consent was required with respect thereto; provided that GPC Biotech may redact confidential portions of any such modifications and amendments to the extent that they do not impair Yakults
ability to exercise and enjoy its rights and benefits under this Agreement;



- 50 -

(c)GPC Biotech shall not terminate the Spectrum Agreement in whole or with respect to Japan,
without Yakults prior written consent;

(d)GPC Biotech shall promptly furnish Yakult with copies of all reports and other
communications GPC Biotech receives from Spectrum that directly relate to the subject matter of this Agreement, provided that GPC Biotech may redact confidential portions of any such reports and communications to the extent that they do not
relate to the subject matter of this Agreement;

(e)GPC Biotech shall promptly furnish Yakult with copies of all reports and other
communications that GPC Biotech furnishes to Spectrum that directly relate to the subject of this Agreement, and to the extent any such reports or communications relate to the efforts of Yakult under this Agreement, GPC Biotech shall give Yakult a
reasonable opportunity to review and comment upon such reports or communications before they are transmitted to Spectrum, provided that GPC Biotech may redact confidential portions of any such reports and communications to the extent that
they do not relate to the subject matter of this Agreement;

(f)GPC Biotech has provided Yakult with copies of all notices of
breach served by Spectrum on GPC Biotech as of the Effective Date. In addition, GPC Biotech shall furnish Yakult with copies of all notices received by GPC Biotech relating to any alleged breach or default by GPC Biotech under the Spectrum License
Agreement within three (3) Working Days after GPC Biotechs receipt thereof, and, if GPC Biotech cannot or chooses not to cure or otherwise resolve any such alleged breach or default that relates to the subject matter of this Agreement,
GPC Biotech shall so notify Yakult within five (5) Working Days thereafter and allow Yakult, in Yakults sole discretion, to cure or otherwise resolve any such alleged breach or default; and

(g)GPC Biotech, acting in its capacity as licensee of Spectrum and sublicensor of Yakult, shall allow Yakult to enjoy the direct benefit of all
of GPC Biotechs affirmative rights, to the extent they relate to the Spectrum Development Technology and Spectrum Licensed Technology (as each is defined in the Spectrum Agreement) and to Japan, all to the extent that Spectrum has the right to
license or otherwise make available such Patent or Know-how and Inventions to GPC Biotech.

11.4.3 Yakults Right under Termination
of the Spectrum Agreement.In the event of any final decision in the arbitration addressed above in Section 11.4.1(d) on the merits of Spectrums claim of breach of the Spectrum Agreement by GPC Biotech, that entitles Spectrum to
terminate the Spectrum Agreement either in its entirety or with respect to Japan, Yakult shall have a right to terminate this Agreement. Such right to terminate may be exercised within ninety (90) days after receipt by Yakult of (i) all
documentation issued by the arbitrators accompanying and referred to in their decision and (ii) any information reasonably requested by Yakult from GPC Biotech or Spectrum that Yakult deems it necessary to consider with respect to Yakults
rights, obligations, and interests as may be affected by the results of the arbitration. For clarity, termination by Yakult pursuant to this Section 11.4.3 shall not constitute termination by Yakult for breach by GPC Biotech, but shall be
considered termination by Yakult under Section 13.3.

11.5 DISCLAIMER OF WARRANTY.EXCEPT FOR THE EXPRESS WARRANTIES SET FORTH IN THIS ARTICLE 11,
NEITHER PARTY MAKES ANY REPRESENTATIONS OR GRANTS ANY WARRANTIES, EXPRESS OR IMPLIED, EITHER IN FACT OR BY OPERATION OF LAW, BY STATUTE OR OTHERWISE, AND EACH PARTY SPECIFICALLY DISCLAIMS ANY OTHER WARRANTIES, WHETHER WRITTEN OR ORAL, OR EXPRESS OR
IMPLIED, INCLUDING ANY WARRANTY OF QUALITY, MERCHANTABILITY OR FITNESS FOR A PARTICULAR USE OR PURPOSE OR ANY WARRANTY AS TO THE VALIDITY OF ANY PATENTS OR THE NON-INFRINGEMENT OF ANY INTELLECTUAL PROPERTY RIGHTS OF THIRD PARTIES.

ARTICLE 12

INDEMNITY

12.1 Indemnification of GPC Biotech.Yakult shall indemnify GPC Biotech, its Affiliates and their respective directors,
officers, members of supervisory and management boards, employees, licensors and agents, and defend and save each of them harmless, from and against any and all losses, damages, liabilities, costs and expenses (including reasonable attorneys
fees and expenses) (collectively, Losses) in connection with any and all suits, investigations, claims or demands of Third Parties (collectively, Third Party Claims) arising from or occurring as a result of:
(a) the breach by Yakult or its Affiliates of any term of this Agreement; (b) the negligence, gross negligence, or intentional misconduct on the part of Yakult or its Affiliates in performing their obligations under this Agreement; or
(c) the Development, Commercialization or other use by Yakult or its Affiliates of the Licensed Compound or the Licensed Product, except for those Losses which GPC Biotech has an obligation to indemnify Yakult pursuant to Section 12.2 or
under the Quality Agreement, as to which Losses each Party shall indemnify the other to the extent of their respective liability; provided, however, that Yakult shall not be obligated to indemnify GPC Biotech for any Losses to the
extent that such Losses arise as a result of gross negligence or intentional misconduct on the part of GPC Biotech or any of its Affiliates.

12.2 Indemnification of Yakult.GPC Biotech shall indemnify Yakult, its Affiliates and their respective directors, officers, employees and agents, and defend and save each of them harmless, from and against any and all Losses in
connection with any and all Third Party Claims arising from or occurring as a result of: (a) the breach by GPC Biotech of this Agreement; (b) the negligence, gross negligence, or intentional misconduct on the part of GPC Biotech in
performing its obligations under this Agreement; or (c) the Development, Commercialization or other use by GPC Biotech of the Licensed Compound or Licensed Product in the Territory, except for those Losses for which Yakult has an obligation to
indemnify GPC Biotech and its Affiliates pursuant to Section 12.1, as to which Losses each Party shall indemnify the other to the extent of their respective liability for the Losses; provided, however, that GPC Biotech shall not
be obligated to indemnify Yakult for any Losses to the extent that such Losses arise as a result of gross negligence or intentional misconduct on the part of Yakult or any of its Affiliates.



- 52 -



---

12.3 Notice of Claim.All indemnification claims in respect of a Party, its Affiliates or their
respective directors, officers, employees and agents shall be made solely by such Party to this Agreement (the Indemnified Party). The Indemnified Party shall give the indemnifying Party prompt written notice (an
Indemnification Claim Notice) of any Losses or discovery of fact upon which such indemnified Party intends to base a request for indemnification under Section 12.1 or 12.2, but in no event shall the indemnifying Party be
liable for any Losses that result from any delay in providing such notice. Each Indemnification Claim Notice must contain a description of the claim and the nature and amount of such Loss (to the extent that the nature and amount of such Loss is
known at such time). The Indemnified Party shall furnish promptly to the indemnifying Party copies of all papers and official documents received in respect of any Losses and Third Party Claims.

12.4 Control of Defense. At its option, the indemnifying Party may assume the defense of any Third Party Claim by giving written notice to
the Indemnified Party within thirty (30) days after the indemnifying Partys receipt of an Indemnification Claim Notice. The assumption of the defense of a Third Party Claim by the indemnifying Party shall not be construed as an
acknowledgment that the indemnifying Party is liable to indemnify the 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. Upon assuming the defense of a Third Party Claim, the indemnifying Party may appoint as lead counsel in the defense of the Third Party Claim any legal counsel selected by the indemnifying Party. In the event
the indemnifying Party assumes the defense of a Third Party Claim, the Indemnified Party shall immediately deliver to the indemnifying Party all original notices and documents (including court papers) received by the Indemnified Party in connection
with the Third Party Claim. Should the indemnifying Party assume the defense of a Third Party Claim, except as provided in Section 12.4.1, the indemnifying Party shall not be liable to the Indemnified Party for any legal expenses subsequently
incurred by such Indemnified Party in connection with the analysis, defense or settlement of the Third Party Claim. In the event that it is ultimately determined that the indemnifying Party is not obligated to indemnify, defend or hold harmless the
Indemnified Party from and against the Third Party Claim, the Indemnified Party shall reimburse the indemnifying Party for any and all costs and expenses (including attorneys fees and costs of suit) and any Third Party Claims incurred by the
indemnifying Party in its defense of the Third Party Claim.

12.4.1 Right to Participate in Defense. Without limiting
Section 12.4 above, any Indemnified Party shall be entitled to participate in, but not control, the defense of such Third Party Claim and to employ counsel of its choice for such purpose; provided, however, that such employment
shall be at the Indemnified Partys own expense unless, subject to the consent of an insurer, if applicable, (a) the employment thereof has been specifically authorized by the indemnifying Party in writing, (b) the indemnifying Party
has failed to assume the defense and employ counsel in accordance with Section 12.4 (in which case the Indemnified Party shall control the defense) or (c) the interests of the Indemnified Party and the indemnifying Party with respect to
such Third Party Claim are sufficiently adverse to prohibit the representation by the same counsel of both parties under Applicable Law, ethical rules or equitable principles.



- 53 -



---

12.4.2 Settlement. With respect to any Third Party Claims relating solely to the payment of
money damages in connection with a Third Party Claim and that shall not result in the Indemnified Partys becoming subject to injunctive or other relief or otherwise adversely affecting the business of the Indemnified Party in any manner, and
as to which the indemnifying Party shall have acknowledged in writing the obligation to indemnify the Indemnified Party hereunder, the indemnifying Party shall have the sole right to consent to the entry of any judgment, enter into any settlement or
otherwise dispose of such Loss, on such terms as the indemnifying Party, in its sole discretion, shall deem appropriate. With respect to all other Losses in connection with Third Party Claims, where the indemnifying Party has assumed the defense of
the Third Party Claim in accordance with Section 12.4.1, the indemnifying Party shall have authority to consent to the entry of any judgment, enter into any settlement or otherwise dispose of such Loss provided it obtains the prior
written consent of the Indemnified Party (which consent shall not be unreasonably withheld or delayed). The indemnifying Party shall not be liable for any settlement or other disposition of a Loss by the Indemnified Party that is reached without the
written consent of the indemnifying Party. Regardless of whether the indemnifying Party chooses to defend or prosecute any Third Party Claim, no Indemnified Party shall admit any liability with respect to or settle, compromise or discharge, any
Third Party Claim without the prior written consent of the indemnifying Party, such consent not to be unreasonably withheld or delayed.

12.4.3 Cooperation. Regardless of whether the indemnifying Party chooses to defend or prosecute any Third Party Claim, the Indemnified Party shall, and shall cause each Indemnified Party to, cooperate in the defense or
prosecution thereof and shall furnish such records, information and testimony, provide such witnesses and attend such conferences, discovery proceedings, hearings, trials and appeals as may be reasonably requested in connection therewith. Such
cooperation shall include access during normal business hours afforded to indemnifying Party to, and reasonable retention by the Indemnified Party of, records and information that are reasonably relevant to such Third Party Claim, and making
indemnified Parties and other employees and agents available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder, and the indemnifying Party shall reimburse the Indemnified Party for
all its reasonable out-of-pocket expenses in connection therewith.

12.4.4 Expenses. Except as provided above, the costs and
expenses, including fees and disbursements of counsel, incurred by the Indemnified Party in connection with any claim shall be reimbursed on a Calendar Quarter basis by the indemnifying Party, without prejudice to the indemnifying Partys right
to contest the Indemnified Partys right to indemnification and subject to refund in the event the indemnifying Party is ultimately held not to be obligated to indemnify the Indemnified Party.

12.5 Limitation on Damages and Liability.EXCEPT IN CIRCUMSTANCES OF GROSS NEGLIGENCE OR INTENTIONAL MISCONDUCT BY A PARTY OR ITS AFFILIATES, OR
WITH RESPECT TO LOSSES INDEMNIFIED UNDER SECTION 12.1 OR 12.2, NO PARTY OR ANY OF THEIR RESPECTIVE AFFILIATES SHALL BE LIABLE FOR SPECIAL, INDIRECT, INCIDENTAL OR CONSEQUENTIAL DAMAGES, OR FOR LOST PROFITS, MILESTONES OR ROYALTIES, WHETHER IN
CONTRACT, WARRANTY, NEGLIGENCE, TORT, STRICT LIABILITY OR OTHERWISE, ARISING

OUT OF (a) THE DEVELOPMENT, MANUFACTURE, COMMERCIALIZATION OR OTHER USE OF THE LICENSED PRODUCT OR LICENSED COMPOUND UNDER THIS AGREEMENT, (b) THE
USE OF OR REFERENCE TO ANY PATENTS, INFORMATION, CLINICAL DATA, INTELLECTUAL PROPERTY RIGHT OR REGULATORY DOCUMENTATION OR (c) ANY BREACH OF OR FAILURE TO PERFORM ANY OF THE PROVISIONS OF THIS AGREEMENT.

12.6 Insurance.Each Party shall have and maintain such type and amounts of liability insurance covering the
Manufacture, Development, use and sale of the Licensed Product as is normal and customary in the pharmaceutical industry generally for parties similarly situated, and shall upon request provide the other Party with a copy of its policies of
insurance in that regard, along with any amendments and revisions thereto. Each Party shall provide the other Party thirty (30) days advance written notice of the termination of coverage in its insurance program. Without limiting the
generality of the foregoing, at a minimum, Yakult shall maintain during any period in which Yakult has indemnification obligations to GPC Biotech, (a) products liability/completed operations coverage with a minimum indemnity limit of Two
Billion Four Hundred Million Japanese Yen (JPY 2,400,000,000) per claim and in the aggregate and (b) a global logistics insurance policy with a minimum indemnity limit of One Billion Japanese Yen (JPY 1,000,000,000) per occurrence and
insurance on product inventory at processor locations of One Billion Two Hundred Million Japanese Yen (JPY 1,200,000,000) per occurrence. Such policies shall (x) be provided by insurance carrier(s) reasonably acceptable to GPC Biotech, and
(y) show GPC Biotech as additional insured and loss payee, as its interests may appear. Such policies shall remain in effect throughout the term of this Agreement and shall not be cancelled or subject to a reduction of coverage without the
prior written authorization of GPC Biotech. Should Yakult at any time or for any reason fail to obtain the insurance required herein, or should such insurance be cancelled or reduced below the above limits, GPC Biotech shall have the right to
procure the same at Yakults expense. GPC Biotech shall have the right to offset any such expense that is owed by Yakult but not paid against any payments owed by GPC Biotech, if any, under this Agreement.

ARTICLE 13

TERM AND TERMINATION

13.1 Term.This Agreement shall commence upon the Effective Date and shall continue unless and until terminated in accordance
with this Article 13.

13.2 Termination of this Agreement in its Entirety for Material Breach.

13.2.1 Notice.

(a)In the
event that either Party believes that the other Party is in breach of any of its material obligations under this Agreement, then such Party (the Non-Breaching Party) may deliver notice specifying such breach and its claim of right
to terminate to the other Party (the Notified Party). In the case of a payment default of amounts not subject to a good faith Dispute by Yakult, Yakult shall have ten (10) days to cure such default.



- 55 -



---

(b)Based on the breach and claim of right to terminate specified in the notice delivered under
subsection (a) (except in the case of a payment default), the Parties shall enter into good faith negotiations to seek a mutually agreeable resolution for a period of not more than sixty (60) days.

(c)If a resolution under subsection (b) is not attained within sixty (60) days, the Notified Party shall have thirty (30) days to
cure such breach.

(d)If such breach cannot be cured within such thirty (30)-day period, the Notified Party may elect to deliver
to the Non-Breaching Party within such thirty (30)-day period a written plan to cure such breach within a timeframe that is reasonably prompt in light of the circumstances then prevailing, and the Non-Breaching Party shall approve or reject, in the
Non-Breaching Partys sole and absolute discretion, such proposed plan by written notice to the Notified Party. If the Non-Breaching Party approves such proposed plan, then the thirty (30)-day cure period shall be extended in accordance with
the terms of such approved plan, and the Notified Party shall use Commercially Reasonable Efforts to carry out such plan and cure the breach in accordance therewith.

13.2.2 Failure to Cure.If the Notified Party fails to cure a breach as provided for in Section 13.2.1, the Non-Breaching Party may provide notice of termination of this Agreement in its entirety
immediately upon such failure, which notice shall take effect immediately upon delivery.

13.3 Termination by Yakult.If Yakult
reasonably determines that it is not feasible for Yakult to pursue the Development or Commercialization of the Licensed Product in Japan due to a scientific, technical, regulatory or commercial reason, including (a) safety or efficacy concerns,
including Adverse Event Experiences with respect to the Licensed Product or (b) concerns relating to the present or future marketability or profitability of the Licensed Product, then Yakult shall promptly notify GPC Biotech in writing of such
determination and provide GPC Biotech with the pertinent information with respect thereto. Promptly following the receipt of such notice from Yakult, the Parties shall meet and discuss any amendments to this Agreement to address Yakults
concerns. If the Parties are not able to agree on such amendments within ninety (90) days and if Yakult still reasonably believes that it is not feasible for Yakult to pursue the development, launch or sale of the Licensed Product in Japan,
Yakult may terminate this Agreement upon ninety (90) days prior written notice to GPC Biotech.

13.4 Termination by GPC
Biotech.

13.4.1In the event that Yakult or any of its Affiliates, anywhere in the Territory, institutes, prosecutes or
otherwise participates in (or in any way aids any Third Party in instituting, prosecuting or participating in), at law or in equity or before any administrative or regulatory body, including the U.S. Patent and Trademark Office or its foreign
counterparts, any claim, demand, action or cause of action for declaratory relief, damages or any other remedy or for an enjoinment, injunction or any other equitable remedy, including any interference, re-examination, opposition or any similar
proceeding, (a) alleging that any claim in a GPC Biotech Patent is invalid, unenforceable or otherwise not patentable or would not be infringed by Yakults activities absent the rights and licenses granted hereunder or (b) that
attacks, disputes or contests



- 56 -



---

the validity of or ownership of a Product Trademark or any registrations issuing with respect thereto, GPC Biotech shall have the right to immediately
terminate this Agreement, on written notice to Yakult; provided, however, that the foregoing shall not apply to (x) any such claim or Product Trademark that has been finally adjudged unenforceable or invalid (with no further opportunity
for appeal) by a court of competent jurisdiction and (y) any defense asserted by Yakult or any of its Affiliates to any claim or action brought by [***] for infringement of any of the GPC Biotech Patents by Yakult or any of its Affiliates in
connection with Yakults (or such Affiliates) Development or Commercialization of the Licensed Product in Japan as contemplated by this Agreement.

13.4.2If Yakult or its ultimate parent corporation proposes a Change of Control, after the Effective Date and during the term of this Agreement, upon any public announcement of such proposed Change of Control,
Yakult shall provide GPC Biotech with prompt written notice of the proposed Change of Control in reasonable detail (the Yakult Change of Control Notice). If the Change of Control that is described in the Yakult Change of Control
Notice involves a Third Party that has a Competitive Program, then, unless the Parties agree otherwise in writing, Yakult (or its successor) or acquirer, as the case may be, (the Merger Party) shall, within forty-five
(45) days after the date of the Change of Control, notify GPC Biotech whether such Merger Party intends to: (x) cease, or cause its relevant Affiliate to cease, the Competitive Program; (y) divest, or cause its relevant Affiliate to
divest, whether by license or otherwise, the Competitive Program; or (z) terminate this Agreement pursuant to Section 13.3, to the extent applicable.

(a)If the Merger Party notifies GPC Biotech in writing within such forty-five (45)-day period that it intends to cease or cause its relevant Affiliate to cease the Competitive Program, the Merger Party or, if
applicable, its Affiliates shall (i) promptly cease the Competitive Program as quickly as possible with due regard for patient safety and the rights of any subjects that are participants in any clinical studies or post-approval studies relating
to the Competitive Program and Applicable Law; and (ii) keep GPC Biotech reasonably informed of its efforts and progress in effecting such cessation of activities and shall provide a written summary of such efforts to GPC Biotech each Calendar
Quarter until completed.

(b)If the Merger Party notifies GPC Biotech in writing within such forty-five (45)-day period that it
intends to divest such Competitive Program, the Merger Party or its Affiliate shall use all reasonable efforts to effect such divestiture as quickly as possible and in any event within one hundred twenty (120) days of the Merger Partys
delivery of such written notice to GPC Biotech and shall keep GPC Biotech reasonably informed of its efforts and progress in effecting such divestiture and shall provide a written summary of such efforts each Calendar Quarter until completed. If the
Merger Party or its Affiliate effects such divestiture by way of one or more sublicenses, the licensor shall be entitled to receive license fees, milestones and royalties on sales of any products developed pursuant to the Competitive Program so
divested, [***]. If, notwithstanding such reasonable efforts, the Merger Party is not able to effect such a divestiture within such one hundred twenty (120)-day period, it shall advise GPC Biotech in writing of its inability to effect such
divestiture within such time period and shall

---

instead terminate such Competitive Program as provided in Section 13.4.2(a) (and shall, as reasonably necessary, have an additional thirty
(30) days within which to complete such termination).

(c)If the Merger Party notifies GPC Biotech in writing within such
forty-five (45)-day period that it intends to terminate this Agreement, this Agreement shall terminate immediately upon receipt of such notice by GPC Biotech.

(d)If the Merger Party fails to provide such notice within such forty-five (45)-day period, or having provided such notice, fails to carry out the designated actions set forth in Section 13.4.2(a),
(b) or (c), then, unless the Parties agree otherwise, GPC Biotech shall have the right to terminate this Agreement effective immediately upon GPC Biotechs providing written notice thereof to the Merger Party.

13.4.3During the term of the Agreement, in the event that Yakult or its ultimate parent corporation undergoes a Change of Control transaction and
Yakult does not terminate this Agreement pursuant to Section 13.3, the Merger Party shall be bound by the obligations of this Agreement, including any Development Plan existing at the time of the consummation of the Change of Control and all
diligence obligations with respect thereto. In the event that a Development Plan has not been approved by the SC prior to the consummation of the Change of Control transaction, such Merger Party shall provide a proposed Development Plan as provided
in Section 3.2.1 within ninety (90) days thereof, which plan shall be subject to written approval by GPC Biotech, such approval not to be unreasonably withheld or delayed. Any Disputes regarding a Development Plan proposed pursuant to this
Section (or amendments to an existing Development Plan) and all other Disputes that would have been deemed Yakult Resolved Committee Disputes in the absence of such Change of Control transaction, shall be resolved in accordance with
Section 14.6.1 and any Arbitration Matters resulting therefrom shall be resolved pursuant to expedited arbitration in accordance with Section 14.6.2(b).

13.5 Termination Upon Insolvency.Either Party may terminate this Agreement if, at any time, the other Party or its ultimate parent corporation shall file in any court or agency pursuant to any statute or
regulation of any state, country or jurisdiction, a petition in bankruptcy or insolvency or for reorganization or for an arrangement or for the appointment of a receiver or trustee of that Party or of its assets, or if the other Party or its
ultimate parent corporation shall be served with an involuntary petition against it, filed in any insolvency proceeding, and such petition shall not be dismissed within sixty (60) days after the filing thereof, or if the other Party or its
ultimate parent corporation shall propose or be a party to any dissolution or liquidation, or if the other Party or its ultimate parent corporation shall make an assignment for the benefit of its creditors.

13.6 Rights in Bankruptcy.All rights and licenses granted under or pursuant to this Agreement by Yakult or GPC Biotech 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 or applicable bankruptcy laws outside the United
States. The Parties agree that the Parties, as licensees of such rights under this Agreement, shall retain and may fully exercise all of their rights and elections under such bankruptcy laws. The Parties further agree that, in the event of the
commencement of a



- 58 -



---

bankruptcy proceeding by or against either Party under such bankruptcy laws, the Party hereto that is not a Party to such proceeding shall be entitled to a
complete duplicate of (or complete access to, as appropriate) any such intellectual property and all embodiments of such intellectual property, which, if not already in the non-subject Partys possession, shall be promptly delivered to it
(a) upon any such commencement of a bankruptcy proceeding upon the non-subject Partys written request therefor, unless the Party subject to such proceeding elects to continue to perform all of its obligations under this Agreement or
(b) if not delivered under (a) above, following the rejection of this Agreement by or on behalf of the Party subject to such proceeding upon written request therefor by the non-subject Party.

13.7 Consequences of Termination. Upon any termination of this Agreement in its entirety:

13.7.1 Termination of Licenses. All licenses and sublicenses granted to Yakult by GPC Biotech under this Agreement shall terminate, and Yakult and
its Affiliates shall have no further right in or to the GPC Biotech Patents, or to use the GPC Biotech Know-How, Product Trademarks or GPC Biotechs Corporate Names. Except as provided in Section 13.7.2, all licenses and sublicenses
granted to GPC Biotech by Yakult under this Agreement shall terminate, GPC Biotech and its Affiliates shall have no further right in or to the Yakult Patents, or to use the Yakult Know-How.

by Yakult), Joint Know-How (to the extent Controlled by Yakult), Yakult Know-How and Yakult Patents, solely to Develop, Manufacture, Commercialize and otherwise use the Licensed Compound and the Licensed Product; provided, however,
that (a) upon the Initial Regulatory Approval of Satraplatin in the United States, such license shall automatically become, with respect to the GPC Biotech Territory, a perpetual, irrevocable, exclusive (including with regard to Yakult and its
Affiliates), royalty-free license, with the right to grant sublicenses (through multiple tiers of sublicensees); and (b) with respect to Japan, at GPC Biotechs option, such license shall become a perpetual, irrevocable, exclusive
(including with regard to Yakult and its Affiliates), royalty-bearing license, with the right to grant sublicenses (through multiple tiers of sublicensees), subject to an agreement by the Parties on an applicable royalty rate and other related terms
and conditions to be negotiated in good faith.

13.7.3 Retention of Payments. Any payments received by GPC Biotech under

13.7.5 Transfer of Regulatory Documentation and Clinical Data.In the event of any termination of
this Agreement, Yakult shall and does hereby automatically and without any further consideration relinquish its rights hereunder and assign and cause its Affiliates to assign to GPC Biotech (or its designee) without further compensation therefor,
all right, title and interest, if any, in and to all Clinical Data, Regulatory Documentation and Regulatory Approvals (including all Yakult Regulatory Documentation) relating to the Licensed Product.

13.7.6 Return of Information and Materials.Without limitation to Section 10.7, and except as provided in Sections 13.7.5 and 13.7.7, each
Party (the Returning Party), at the request of the other Party, shall return or, at the election of the other Party, use reasonable efforts to destroy, and thereafter provide to the other Party written certification evidencing
such destruction, all data, files, records and other materials in its possession or control containing or comprising the other Partys Information, inventions, Improvements, Clinical Data, Regulatory Documentation or other Confidential
Information with respect to the Licensed Product, except that each Party may retain (a) one copy of such data, files or materials for archival purposes and as reasonably necessary to demonstrate compliance with the terms and conditions of this
Agreement and (b) such additional copies of or any computer records or files containing such data, files or materials that have been created solely by the Returning Partys automatic archiving and back-up procedures, to the extent created
and retained in a manner consistent with the Returning Partys standard archiving and back-up procedures, but not for any other use or purpose.

13.7.7 Sale of Inventory. In the event of any termination of this Agreement, Yakult shall have the right for twelve (12) months after the effective date of such termination to dispose of all Licensed

foregoing, in the event of termination by GPC Biotech pursuant to Section 13.2, then, at GPC Biotechs request, Yakult shall, at Yakults cost and expense, transfer to GPC Biotech or destroy all of Yakults inventory and work-in
process of the Licensed Product.

13.7.8 Assistance. Without limiting GPC Biotechs rights under other provisions of this
Article 13, in the event of any termination pursuant to this Article 13, Yakult shall, and shall cause its Affiliates to, at the request of GPC Biotech, provide GPC Biotech with such assistance as is reasonably necessary to effectuate a smooth and
orderly transition of any such Development and Commercialization activities, including any ongoing Clinical Studies or Post Approval Studies, to GPC Biotech or its designee so as to minimize any disruption of such activities, including, at the
request of GPC Biotech, the assignment of any Clinical Data, Regulatory Documentation and related contracts, and the transfer of any materials related to the Licensed Product. In performing its obligations under this Section 13.7.8, Yakult
shall, and shall cause its Affiliates to, cooperate with GPC Biotech to effect such transfers and assignments in an orderly fashion and shall provide to GPC Biotech or its designee any copies of relevant documents and rights of reference or access
necessary to allow GPC Biotech to Develop, Manufacture, Commercialize and otherwise use the Licensed Compound and Licensed Product in Japan. Reasonable expenses under this Section shall be borne by Yakult in the event of termination by GPC Biotech,
and by GPC Biotech in the event of termination by Yakult. Assistance by Yakult under this Section shall not be required beyond hundred eighty (180) days from the date of termination.

13.8 Accrued Rights; Surviving Obligations.

13.8.1 Accrued Rights. Termination or expiration of this Agreement for any reason shall be without prejudice to any rights that shall have
accrued to the benefit of a Party prior to such termination or expiration. Such termination or expiration shall not relieve a Party from obligations that are expressly indicated to survive the termination or expiration of this Agreement.

13.8.2 Survival. Without limiting the foregoing, Articles 7, 10 and 12, and Sections 2.2, 3.3.5, 6.2, 6.3, 6.4, 6.5, 6.6, 6.7 (each of

this Agreement for any reason.

respect to Japan or in its entirety, including a termination arising out of a material breach by GPC Biotech decided under Section 15 of the Spectrum Agreement, the sublicense granted by GPC Biotech to Yakult under this Agreement shall be, as
provided in Section 15.7 of the Spectrum Agreement regarding survival of sublicenses, automatically assigned to Spectrum. Spectrum shall thereafter receive all benefits of GPC Biotech and be obligated to perform all covenants of GPC Biotech
under this Agreement in the place and stead of GPC Biotech, and GPC Biotech shall not retain any such rights and duties. Yakult shall thereafter receive all of its benefits and be obligated to perform all of its covenants under this Agreement for
the benefit of Spectrum, and shall in no event incur, merely as the result of the assignment of this Agreement to Spectrum, any obligation for any additional payments or royalties or any other financial obligation not already provided for in this
Agreement.

ARTICLE 14

MISCELLANEOUS

14.1 Force Majeure.Neither Party shall be held liable or responsible to the
other Party or be deemed to have defaulted under or breached this Agreement for failure or delay in fulfilling or performing any term of this Agreement when such failure or delay is caused by or results from events beyond the reasonable control of
the non-performing Party, including fires, floods, earthquakes, embargoes, shortages, epidemics, quarantines, war, acts of war (whether war be declared or not), terrorist acts, insurrections, riots, civil commotion, strikes, lockouts or other labor
disturbances (whether involving the workforce of the non-performing Party or of any other Person), acts of God or acts, omissions or delays in acting by any governmental authority. The non-performing Party shall notify the other Party of such force
majeure within thirty (30) days after such occurrence by giving written notice to the other Party stating the nature of the event, its anticipated duration, and any action being taken to avoid or minimize its effect. The suspension of
performance shall be of no greater scope and no longer duration than is necessary and the non-performing Party shall use commercially reasonable efforts to remedy its inability to perform. In the event that such force majeure event lasts for more
than ninety (90) days, such other Party shall have the right to terminate this Agreement upon sixty (60) days written notice to the non-performing Party.

14.2 Non-Solicitation.During the term of this Agreement and for a period of one (1) year thereafter, neither Party shall actively recruit or solicit any employee of the other Party or its Affiliates. For
the avoidance of doubt, nothing shall limit a Party from engaging in general recruitment efforts through advertisements or recruiting through head-hunters so long as the employees of the other Party and its Affiliates are not
specifically targeted in such recruitment effort.

14.3 Assignment.Without the prior written consent of the other Party, neither
Party shall sell, transfer, assign, delegate, pledge or otherwise dispose of, whether voluntarily, involuntarily, by operation of law or otherwise, this Agreement or any of its rights or duties hereunder; provided, however, that
(a) GPC Biotech may, without such consent, assign this Agreement and its rights and obligations hereunder to an Affiliate, to the purchaser of its rights to the GPC Biotech Patents, GPC Biotech Know-How, GPC Biotech Regulatory Documentation or
Product Trademarks or to its successor entity or acquirer in the event of a merger, consolidation or change in control of GPC Biotech and (b) subject to Sections 13.4.2 and 13.4.3, Yakult may, without such consent, assign this Agreement and its
rights and obligations hereunder to an Affiliate or to its successor entity or acquirer in the event of a merger, consolidation or Change of Control of Yakult; provided further that in either case ((a) or (b)), the assigning Party remains
jointly and severally liable with the relevant Affiliate or Third Party assignee under this Agreement. Any attempted assignment or delegation in violation of the preceding sentence shall be void and of no effect. All validly assigned and delegated
rights and obligations of the Parties hereunder shall be binding upon and inure to the benefit of and be enforceable by and against the successors and permitted assigns of GPC Biotech or Yakult, as the case may be.



- 62 -



---

14.4 Severability.If any provision of this Agreement is held to be illegal, invalid or
unenforceable under any present or future law, and if the rights or obligations of either Party under this Agreement will not be materially and adversely affected thereby, (a) such provision shall be fully severable, (b) this Agreement
shall be construed and enforced as if such illegal, invalid or unenforceable provision had never comprised a part hereof, (c) the remaining provisions of this Agreement shall remain in full force and effect and shall not be affected by the
illegal, invalid or unenforceable provision or by its severance herefrom and (d) in lieu of such illegal, invalid or unenforceable provision, there shall be added automatically as a part of this Agreement a legal, valid and enforceable
provision as similar in terms to such illegal, invalid or unenforceable provision as may be possible and reasonably acceptable to the Parties. To the fullest extent permitted by applicable law, each Party hereby waives any provision of law that
would render any provision hereof illegal, invalid or unenforceable in any respect.

14.5 Governing Law, Jurisdiction, Venue and
Service.

14.5.1 Governing Law. This Agreement shall be governed by and construed in accordance with the
laws of the State of New York, excluding any conflicts or choice of law rule or principle that might otherwise refer construction or interpretation of this Agreement to the substantive law of another jurisdiction. The Parties agree to exclude the
application to this Agreement of the United Nations Convention on Contracts for the International Sale of Goods.

14.5.2
Jurisdiction. Subject to Sections 14.6 and 14.10, the Parties hereby irrevocably and unconditionally consent to the exclusive jurisdiction of the courts of the State of New York and the United States District Court for the Southern
District of New York for any action, suit or proceeding (other than appeals therefrom) arising out of or relating to this Agreement, and agree not to commence any action, suit or proceeding (other than appeals therefrom) related thereto except in
such courts. The Parties irrevocably and unconditionally waive their right to a jury trial.

14.5.3 Venue. The Parties
further hereby irrevocably and unconditionally waive any objection to the laying of venue of any action, suit or proceeding (other than appeals therefrom) arising out of or relating to this Agreement in the courts of the State of New York or in the
United States District Court for the Southern District of New York, and hereby further irrevocably and unconditionally waive and agree not to plead or claim in any such court that any such action, suit or proceeding brought in any such court has
been brought in an inconvenient forum.

14.5.4 Service. Each Party further agrees that service of any process, summons,
notice or document by registered mail to its address set forth in Section 14.7.2 shall be effective service of process for any action, suit or proceeding brought against it under this Agreement in any such court.

14.6 Dispute Resolution. Except with respect to Yakult Resolved Committee Matters, GPC Biotech Resolved Committee Matters, any dispute governed by
Section 6.10 or as otherwise expressly provided herein, if a dispute arises between the Parties in connection with or relating to this Agreement or any document or instrument delivered in connection herewith (a Dispute), it
shall be resolved pursuant to this Section 14.6.



- 63 -



---

14.6.1 General. Either Party shall have the right to refer any such Dispute to the Chief
Executive Officer of GPC Biotech and the Senior Managing Director of Yakult who shall confer on the resolution of the issue. Any final decision mutually agreed to by such representatives shall be conclusive and binding on the Parties. If such
officers are not able to agree on the resolution of any such issue within fifteen (15) Working Days after such issue was first referred to them, either Party may, by written notice to the other Party, elect to initiate arbitration pursuant to
Section 14.6.2(a) for purposes of having the matter settled, except with respect to Litigable Matters, which shall be resolved in accordance with Section 14.6.3.

14.6.2 Arbitration. Any arbitration under this Agreement (each an Arbitration Matter) shall be administered by the
International Chamber of Commerce under its Rules of Arbitration then in effect (the Arbitration Rules) and as otherwise described in this Section 14.6.2. The arbitration shall take place in (x) New York, New York, if
Yakult elected to initiate arbitration, or (y) Tokyo, Japan, if GPC Biotech elected to initiate arbitration, provided that in any event, (1) the laws of the State of New York, excluding any conflicts or choice of law rule or
principle, shall apply and (2) the proceedings shall be conducted in English.

(a) Full Arbitration. Unless
Section 14.6.2(b) is applicable, the following procedures shall apply:

(i)The Parties shall appoint three arbitrators by
mutual agreement. If the Parties cannot agree on the appointment of one or more arbitrators within thirty (30) days of the demand for arbitration, such arbitrator(s) shall be appointed in accordance with the Arbitration Rules.

(ii)Either Party may apply to the arbitrators for interim injunctive relief until the arbitration decision is rendered or the Arbitration Matter
is otherwise resolved. Either Party also may, without waiving any right or remedy under this Agreement, seek from any court having jurisdiction any injunctive or provisional relief necessary to protect the rights or property of that Party pending
resolution of the Arbitration Matter pursuant to this Section 14.6.2. The arbitrators shall have the authority to grant any equitable and legal remedies that would be available in any judicial proceeding instituted to resolve the Dispute
submitted to such arbitration in accordance with this Agreement; provided, however, that the arbitrators shall not have the power to alter, amend or otherwise affect the terms or the provisions of this Agreement. Judgment upon any
award rendered pursuant to this Section may be entered by any court having jurisdiction over the Parties other assets.

(iii)Each Party shall bear its own costs and expenses and attorneys fees, and the Party that does not prevail in the arbitration proceeding shall pay the arbitrators fees and any administrative fees of arbitration.

(iv)Except to the extent necessary to confirm an award or decision or as may be required by Applicable Law, neither Party may, and the Parties
shall instruct the arbitrators not to, disclose the existence, content, or results of an arbitration without the prior written consent of both Parties. In no event shall an arbitration be initiated after the date when commencement of a legal or
equitable proceeding based on the Arbitration Matter would be barred by the applicable New York statute of limitations.



- 64 -



---

(v)The Parties hereby agree that any payment to be made by a Party pursuant to a decision of the
arbitrators shall be made in Euros, free of any tax or other deduction. The Parties further agree that the decision of the arbitrators shall be the sole, exclusive and binding remedy between them regarding determination of the Arbitration Matters
presented and the Parties hereby waive the right to contest the award in any court or other forum.

(b) Expedited
Arbitration. To the extent the Arbitration Matter involves a Dispute pursuant to the last two sentences of Section 13.4.3 or any other matter that is expressly referred to expedited arbitration elsewhere in this Agreement, the
procedures set forth in Section 14.6.2(a) shall apply, except that the following procedures shall also apply:

(i)For purposes
of arbitration under this Section 14.6.2(b), the arbitrator shall appointed pursuant to Section 14.6.2(a)(i), but shall be a single independent, conflict-free arbitrator (such arbitrator, the Expert), who shall have
sufficient background, expertise and experience to resolve the Arbitration Matter.

(ii)Each Party shall prepare and
submit a written summary of such Partys position and any relevant evidence in support thereof to the Expert within thirty (30) days of the selection of the Expert. Within thirty (30) days after receipt of such summaries by the
Expert, the Expert shall make a determination by selecting the resolution proposed by one of the Parties that as a whole is the most fair and reasonable to the Parties in light of the totality of the circumstances and shall provide the Parties with
a written statement setting forth the basis of the determination in connection therewith. For purposes of clarity, the Expert shall only have the right to select a resolution proposed by one of the Parties in its entirety and without modification.

14.6.3 Litigable Matters. All Litigable Matters (including any Unresolved Committee Matter that is a Litigable Matter)
shall, at the election of either Party, be decided by litigation in accordance with Section 14.5, provided that any Litigable Matter regarding the validity, scope, enforceability, inventorship or ownership of Intellectual Property Rights
shall be submitted by either Party to a court of competent jurisdiction in the country in which such rights apply.

14.7
Notices.

14.7.1 Notice Requirements. Any notice, request, demand, waiver, consent, approval or other communication
permitted or required under this Agreement shall be in writing, shall refer specifically to this Agreement and shall be deemed given only if delivered by hand or sent by facsimile transmission (with transmission confirmed) or by internationally
recognized overnight delivery service that maintains records of delivery, addressed to the Parties at their respective addresses specified in Section 14.7.2 or to such other address as the Party to whom notice is to be given may have provided
to the other Party in accordance with this Section 14.7. Such Notice shall be deemed to have been given as of the date delivered by hand or transmitted by facsimile (with transmission confirmed) or on the third business day (at the place of
delivery) after deposit with an internationally recognized courier service. Any notice delivered by facsimile shall be confirmed by a hard copy delivered as soon as practicable thereafter. This Section 14.7 is not intended to govern the
day-to-day business communications necessary between the Parties in performing their obligations under the terms of this Agreement.

14.8 Entire Agreement.This Agreement, together with the Exhibits attached hereto, sets
forth and constitutes the entire agreement and understanding between the Parties with respect to the subject matter hereof and all prior agreements, understandings, promises and representations, whether written or oral, with respect thereto are
superseded hereby. Each Party confirms that it is not relying on any representations or warranties of the other Party except as specifically set forth herein. No amendment, modification, release or discharge shall be binding upon the Parties unless
in writing and duly executed by authorized representatives of both Parties.

14.9 English Language.This Agreement shall be written
and executed in, and all other communications under or in connection with this Agreement shall be in, the English language. Any translation into any other language shall not be an official version thereof, and in the event of any conflict in
interpretation between the English version and such translation, the English version shall control.

14.10 Equitable Relief.The
Parties acknowledge and agree that the restrictions set forth in Article 10 are reasonable and necessary to protect the legitimate interests of the other Party and that such other Party would not have entered into this Agreement in the absence
of such restrictions, and that any breach or threatened breach of any provision of Article 10 may result in irreparable injury to such other Party for which there will be no adequate remedy at law. In the event of a breach or threatened breach
of any provision of Article 10, the non-breaching Party shall be authorized and entitled to obtain from any court of competent jurisdiction injunctive relief, whether preliminary or permanent, specific performance and an equitable accounting of
all earnings, profits and other benefits arising from such breach, which rights shall be cumulative and in addition to any other rights or remedies to which such non-breaching Party



- 66 -



---

may be entitled in law or equity. Both Parties agree to waive any requirement that the other (a) post a bond or other security as a condition for
obtaining any such relief and (b) show irreparable harm, balancing of harms, consideration of the public interest or inadequacy of monetary damages as a remedy. Nothing in this Section 14.10 is intended, or should be construed, to limit
either Partys right to equitable relief or any other remedy for a breach of any other provision of this Agreement.

14.11 Waiver
and Non-Exclusion of Remedies.Any term or condition of this Agreement may be waived at any time by the Party that is entitled to the benefit thereof, but no such waiver shall be effective unless set forth in a written instrument duly executed
by or on behalf of the Party waiving such term or condition. The waiver by either Party hereto of any right hereunder or of the failure to perform or of a breach by the other Party shall not be deemed a waiver of any other right hereunder or of any
other breach or failure by said other Party whether of a similar nature or otherwise.

14.12 No Benefit to Third Parties.The
representations, warranties, covenants and agreements set forth in this Agreement are for the sole benefit of the Parties hereto and their successors and permitted assigns, and they shall not be construed as conferring any rights on any other
Persons.

14.13 Further Assurance.Each Party shall duly execute and deliver, or cause to be duly executed and delivered, such
further instruments and do and cause to be done such further acts and things, including the filing of such assignments, agreements, documents and instruments, as may be necessary or as the other Party may reasonably request in connection with this
Agreement or to carry out more effectively the provisions and purposes hereof, or to better assure and confirm unto such other Party its rights and remedies under this Agreement.

14.14 Relationship of the Parties.It is expressly agreed that GPC Biotech, on the one hand, and Yakult, on the other hand, shall be independent
contractors and that the relationship between the two Parties shall not constitute a partnership, joint venture or agency. Neither GPC Biotech, on the one hand, nor Yakult, on the other hand, shall have the authority to make any statements,
representations or commitments of any kind, or to take any action, which shall be binding on the other, without the prior written consent of the other Party to do so, such consent not to be unreasonably withheld or delayed. All persons employed by a
Party shall be employees of such Party and not of the other Party and all costs and obligations incurred by reason of any such employment shall be for the account and expense of such Party.

14.15 Counterparts.This Agreement may be executed in two (2) counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument. This Agreement may be executed by facsimile signatures and such signatures shall be deemed to bind each party hereto as if they were original signature.

14.16 References.Unless otherwise specified, (a) references in this Agreement to any Article, Section or Exhibit shall mean references to
such Article, Section or Exhibit of this Agreement, (b) references in any section to any clause are references to such clause of such section and (c) references to any agreement, instrument or other document in this Agreement refer to such
agreement, instrument or other document as originally executed or, if subsequently varied, replaced or supplemented from time to time, as so varied, replaced or supplemented and in effect at the relevant time of reference thereto.
