Except as otherwise indicated below, commencing no later than the Transfer Time, at its cost and expense, Merck Serono shall deliver the Transferred Assets to BioMarin or, as directed by BioMarin, its Affiliates as follows (provided that the unintentional failure of Merck Serono to deliver a Transferred Asset in its physical form as specified below shall not be deemed a breach of this Agreement so long as Merck Serono complies with its obligations set forth in Section 6.12):

(a) Merck Serono hereby grants to BioMarin, and BioMarin hereby accepts, a non-exclusive, non-transferable, sublicensable (solely to BioMarin’s Affiliates and any Third Party acting on BioMarin’s behalf), royalty-free, fully paid-up, license in the Territory to use the Merck Serono Marks solely in connection with (i) the sale and distribution, in accordance with Law, in the Territory of the Transferred Inventory that are packaged or labeled with any Merck Serono Marks and (ii) the promotion of the Product, in accordance with Law, in the Territory through the use of Product Promotional Materials that contain Merck Serono Marks.

Section 4.06 Non-Assignable Assets. To the extent that Merck Serono’s rights under any Transferred Asset may not be conveyed or assigned without the approval, consent or waiver of another Third Party and such approval, consent or waiver has not been obtained prior to the Transfer Time, this Agreement shall not constitute an agreement to assign the same if an attempted assignment would constitute a breach thereof or be unlawful. If any such approval, consent or waiver shall not have been obtained prior to the Transfer Time, Merck Serono shall, and shall cause its Affiliates to, (a) use its commercially reasonable efforts to assist and cooperate with BioMarin to obtain all necessary approvals, consents and waivers to the assignment and transfer thereof. Until any such approval, consent or waiver is obtained and the related Purchased Asset is transferred and assigned to BioMarin or BioMarin’s designee, Merck Serono shall, and shall cause its Affiliates to, use their commercially reasonable efforts to provide to BioMarin substantially comparable benefits thereof and enforce, at the request of and for the account of BioMarin, any rights of Merck Serono arising under any such Transferred Asset against any Third Party. To the extent that BioMarin is provided with benefits of any such Transferred Asset, BioMarin shall perform the obligations of Merck Serono associated with the benefits received by BioMarin thereunder to the extent that such obligations would constitute an Assumed Liability. Once any such approval, consent or waiver for the conveyance or assignment of any such non-assignable asset is obtained, Merck Serono shall, and shall cause its Affiliates to, convey, assign, transfer and deliver such non-assignable asset to BioMarin at no additional cost to BioMarin. For any Transferred Assets which are Assigned Contracts, the transfer of such Assigned Contracts shall be governed by Section 4.07.

Section 4.07 Assigned Contracts. For those Assigned Contracts where Merck Serono has the right to assign the Assigned Contract to a Third Party, the assignment shall be effective at the Transfer Time. For any Assigned Contract which, by its terms, is not assignable, the Parties shall[*] use Commercially Reasonable Efforts to obtain the assignment from the applicable Third Party. Where an Assigned Contract is not assigned to BioMarin at the Transfer Time, Merck Serono shall, at BioMarin’s written request, continue to maintain such Assigned Contract as part of the Transition Services to allow BioMarin to operate under such Assigned Contract and BioMarin shall reimburse Merck Serono for all of Merck Serono’s costs and expenses, including its internal personnel costs at the FTE Rate, in maintaining the Assigned Contract and performing Merck Serono’s obligations thereunder; provided that Merck Serono may provide notice of termination of an Assigned Contract to a Third Party so long as such termination of Assigned Contract is not effective until [*] or later. Following [*], Merck Serono may, at its sole discretion, discontinue using such efforts to obtain consents of Third Parties and may terminate any Assigned Contract that has not been assigned. For the avoidance of doubt, the Parties agree that BioMarin shall, subject to Section 3.02(a)(v), be responsible for all costs relating to all Assigned Contracts after the Transfer Time, whether or not an Assigned Contract has been assigned by the Transfer Time; provided that to the extent that an Assigned Contract is not assigned to BioMarin by [*], BioMarin shall have no obligation for any costs related to terminating such Assigned contract and shall have no obligation for any costs after the earlier of (a) the date Merck Serono terminates such Assigned Contract or (b) such time as Merck Serono is not maintaining the Assigned Contract as part of the Transition Services due to the end of the Initial Transition Services Period or the Subsequent Transition Period, as applicable. To the extent that Merck makes a payment under an Assigned Contract that is allocable on or after the Transfer Time, or BioMarin makes a payment under an Assumed Contract that is allocable prior to the Transfer Time, then the Parties shall agree in good faith on a fair and equitable allocation of such payment and if they are unable to do so within 30 days after the commencement of such good faith negotiations (or such other period as Merck Serono and BioMarin may mutually agree in writing), then Merck Serono and BioMarin shall submit the matter to an independent certified public accounting firm of recognized national standing in the [*], and such accounting firm shall make a determination as to the resolution of such allocation.

ARTICLE VIII. INDEMNIFICATION

Section 8.01 Indemnification.

(a) Indemnification by Merck Serono. Following the License Termination Date, but subject to the provisions of this Section 8.01, Merck Serono shall indemnify, defend and hold harmless BioMarin and its Affiliates, and their respective officers, directors, employees and agents (collectively, “BioMarin Indemnitees”) from and against, and compensate and reimburse the BioMarin Indemnitees for, any and all losses, claims, Proceedings, causes of action, liabilities, damages, judgments, demands, costs and expenses of any kind, whether known or unknown (collectively, “Losses”) asserted against or incurred by any BioMarin Indemnitee arising out of or related to: [*].

(b) Indemnification by BioMarin. Following the License Termination Date, but subject to the provisions of this Section 8.01, BioMarin shall indemnify and hold harmless Merck Serono and its Affiliates, and their respective licensors, licensees, officers, directors, employees and agents (collectively, “Merck Serono Indemnitees”) from and against, and compensate and reimburse the Merck Serono Indemnitees for, any and all Losses asserted against or incurred by any Merck Serono Indemnitee arising out of or related to: [*].

(i) Each Party, on behalf of itself and its respective BioMarin Indemnitees or Merck Serono Indemnitees (each such Person, an “Indemnitee”), agrees to provide the indemnifying Party prompt written notice of any Proceeding for which such Indemnitee intends to assert a right to indemnification under this Agreement (a “Claim”); provided, however, that failure to give such notification shall not affect each applicable Indemnitee’s entitlement to indemnification (or the corresponding indemnifying Party’s indemnification obligations) hereunder except to the extent that the indemnifying Party shall have been prejudiced as a result of such failure. The indemnifying Party shall have the initial right (but not obligation) to defend, settle or otherwise dispose of any Claim for which an Indemnitee intends to assert a right to indemnification under this Agreement as contemplated in the preceding sentence if, and for so long as, the indemnifying Party has recognized in a written notice to the Indemnitee provided within [*] days of such written notice its obligation to indemnify the Indemnitee for any Losses to which such Indemnitee may become subject, including reasonable fees and disbursements of counsel and expenses of reasonable investigation relating to such Claim; provided, however, that if the indemnifying Party assumes control of the defense, settlement or disposition of a Claim, the indemnifying Party shall obtain the written consent of each applicable Indemnitee prior to ceasing to defend, settling or otherwise disposing of the Claim. If the indemnifying Party fails to state in a written notice during such [*] day period its willingness to assume the defense of such a Claim, the BioMarin Indemnitee(s) or Merck Serono Indemnitee(s), as the case may be, shall have the right to defend, settle or otherwise dispose of such Claim, subject to the applicable provides. If there is a disagreement concerning the obligations of a Party hereunder, either the Indemnitee or the indemnifying Party may initiate litigation in a court of competent jurisdiction pursuant to the applicable provisions of Article XI for purposes of having the matter settled in accordance with the terms of this Agreement.

(ii) Notwithstanding Section 8.01(c)(i), the indemnifying Party shall not be entitled to assume the defense of any Claim, if (1) the Claim seeks, or could reasonably be expected to seek, an order, injunction or other equitable relief or relief for other than money damages against the Indemnitee that the Indemnitee reasonably determines cannot be separated from any related claim for money damages or (2) the Claim could reasonably be expected to result in criminal liability. If such equitable relief or other relief portion of the Claim can be so separated from that for money damages, the indemnifying Party shall be entitled to assume the defense of the portion relating to money damages, subject to the provisions of this Section 8.01(c).

(d) Limitations on Indemnification.

(i) The provisions for indemnity under [*] shall be effective only when the aggregate amount of all Losses for all Qualifying Claims for which indemnification is sought from any indemnifying Party exceeds [*], in which case the Indemnitee shall be entitled to indemnification of the Indemnitee’s Losses in excess thereof. In no event shall any indemnifying Party have liability for indemnification under [*], as applicable, for any amount exceeding, in the aggregate, [*]. Notwithstanding the foregoing, the limitations on indemnification under this Section 8.01(d) shall not apply to any indemnification claim arising out of or related to the [*].

(ii) The amount of Losses recovered by an Indemnitee under Section 8.01(a) or Section 8.01(b), as applicable, shall be reduced by (1) any amounts actually recovered by the Indemnitee from a Third Party in connection with such claim and (2) the amount of any insurance proceeds paid to the Indemnitee relating to such claim, in each case ((1) and (2)), net of the Indemnitee’s costs of recovery, any deductible associated therewith to the extent paid and any increase in premiums resulting from such claims. If any amounts referenced in the preceding clauses (1) and (2) are received after payment by the indemnifying Party of the full amount otherwise required to be paid to an Indemnitee pursuant to this Section 8.01, the Indemnitee shall repay to the indemnifying Party, promptly after such receipt, any amount that the indemnifying Party would not have had to pay pursuant to this Section 8.01 had such amounts been received prior to such payment.

(iii) The representations and warranties of Merck Serono and BioMarin contained in this Agreement shall survive the License Termination Date and continue in full force and effect thereafter through and including 11:59 p.m. Pacific time, on the [*] anniversary of the License Termination Date; provided, that the representations and warranties contained in [*] shall remain in full force and effect and shall survive through and including 11:59 p.m. Pacific time, on the [*] anniversary of the License Termination Date. The covenants, agreements and obligations of the Parties contained in this Agreement shall survive until fully performed or discharged, unless otherwise expressly provided herein. In the event notice of any claim for indemnification under Section 8.01(a) or Section 8.01(b) shall have been given within the applicable survival period and such claim has not been finally resolved by the expiration of such survival period, the representations and warranties and covenants, as applicable, that are the subject of such claim shall survive the end of the survival period of such representations or warranties until such claim is finally resolved, but such representations and warranties and covenants shall survive only with respect to any such asserted claim. It is the express intent of the Parties that, if the applicable survival period for an item as contemplated by this Section 8.01(d) is longer than the statute of limitations that would otherwise have been applicable to such item, then, by Contract, the applicable statute of limitations with respect to such item shall be increased to the lengthened survival period contemplated hereby.

(iv) TO THE FULLEST EXTENT PERMITTED BY LAW AND EXCEPT AS A RESULT OF [*], NEITHER BIOMARIN NOR MERCK SERONO SHALL BE LIABLE TO THE OTHER, OR THEIR AFFILIATES OR INDEMNIFIED PARTIES, FOR ANY CLAIMS, DEMANDS OR SUITS FOR CONSEQUENTIAL, INCIDENTAL, SPECIAL, EXEMPLARY, PUNITIVE, INDIRECT OR MULTIPLE DAMAGES, INCLUDING LOSS OF PROFITS, REVENUE OR INCOME, DIMINUTION IN VALUE OR LOSS OF BUSINESS OPPORTUNITY (WHETHER OR NOT FORESEEABLE AT THE EXECUTION DATE), CONNECTED WITH OR RESULTING FROM ANY BREACH OF THIS AGREEMENT OR ANY ACTIONS UNDERTAKEN IN CONNECTION HEREWITH, OR RELATED HERETO, INCLUDING ANY SUCH DAMAGES WHICH ARE BASED UPON BREACH OF CONTRACT, TORT (INCLUDING NEGLIGENCE AND MISREPRESENTATION), BREACH OF WARRANTY, STRICT LIABILITY, STATUTE, OPERATION OF LAW OR ANY OTHER THEORY OF RECOVERY, OTHER THAN TO THE EXTENT SUCH DAMAGES ARE AWARDED TO A THIRD PARTY IN ANY THIRD PARTY CLAIM.

(v) For the avoidance of doubt, no Indemnitee shall be entitled to indemnification under this Section 8.01 in respect of any Loss to the extent such Indemnitee has been previously indemnified or reimbursed in respect of such Loss pursuant to any other provision of this Agreement.

(e) Tax Treatment of Indemnification Payments. All payments made pursuant to this Section 8.01 shall be treated as adjustments to the Transfer Consideration for all Tax purposes, unless otherwise required by Law.

(f) Exclusive Remedy. Subject to Section 11.02(c) or otherwise provided in this Agreement, each Party acknowledges and agrees that, following the Transfer Time, the remedies provided for in this Section 8.01 shall be the sole and exclusive remedies for claims and damages available to the Parties and their respective Affiliates arising out of or relating to this Agreement and the transactions contemplated hereby, except that nothing herein shall limit the liability of either Party for fraud, willful breach or intentional misrepresentation. Notwithstanding anything to the contrary contained in this Agreement, no breach of any representation, warranty, covenant or agreement contained herein shall, after the consummation of the transactions contemplated by this Agreement, give rise to any right on the part of BioMarin, on the one hand, or Merck Serono, on the other hand, to rescind this Agreement or any of the transactions contemplated hereby.

(g) Investigation. The right to indemnification or any other remedy based on representations, warranties, covenants or agreements of Merck Serono and BioMarin in this Agreement or any other document, certificate or other instrument required to be delivered by Merck Serono or BioMarin under this Agreement will not be affected by any investigation conducted (or capable of being conducted) by any Indemnitee or any other Person at any time, or any knowledge acquired (or capable of being acquired) by any Indemnitee or any other Person at any time, whether before or after the execution and delivery of this Agreement or the License Termination Date, with respect to the accuracy or inaccuracy of, or compliance with, any such representation, warranty, covenant or agreement. Proceeding with the consummation of the

transactions contemplated by this Agreement notwithstanding any inaccuracy of any representation or warranty, or non-performance of or non-compliance with any covenant or agreement of a Party hereunder, will not affect the right to indemnification or other remedy based on such representations, warranties, covenants and agreements.
