(b)Without limiting the provisions of Section ‎2.04(a), as a precaution to address the possibility that, notwithstanding that Seller and Purchaser expressly intend and expect that the sale, assignment, transfer, contribution and conveyance of the Transferred Assets hereunder shall be a true, absolute and irrevocable sale and assignment and a true, absolute and irrevocable contribution for all purposes, to protect the interest of Purchaser in the event that such sale and assignment is recharacterized as other than a true sale or true contribution or such sale, transfer or contribution will for any reason be ineffective or unenforceable as such, as determined in a judicial, administrative or other proceeding (any of the foregoing being a “Recharacterization”), Seller does hereby grant to Purchaser a continuing security interest (which shall be of first priority) in all of Seller’s right, title and interest in, to and under the Transferred Assets, whether now or hereafter existing, and any and all “proceeds” thereof (as such term is defined in the UCC), in each case, for the benefit of Purchaser as security for the prompt and complete payment of a loan deemed to have been made in an amount equal to the Purchase Price together with the performance when due of all of Purchaser’s obligations now or hereafter existing under this Agreement and

the other Transaction Documents, which security interest will, upon the filing of a duly prepared financing statement in the appropriate filing office, be perfected and prior to all other Liens on the rights of Seller to the Transferred Assets. In the event of a Recharacterization, Purchaser will have, in addition to the rights and remedies which it may have under this Agreement, all other rights and remedies provided to a secured creditor after default under the UCC and other Applicable Law, which rights and remedies will be cumulative. This Agreement shall constitute a security agreement in respect of such security interest.

(c)Seller and Purchaser intend that their operations and business would not be substantively consolidated in the event of an Insolvency Event with respect to Seller and that the separate existence of Seller and Purchaser would not be disregarded in the event of an Insolvency Event with respect to Seller.

Notwithstanding the foregoing, Seller’s reasonable decision not to enforce its rights under any Covered Agreement for Roche’s failure to timely remit any due and payable Commercial Payments during any reasonable grace period, which shall not, in any event, extend beyond [***] days, shall not constitute a waiver or consent under any Covered Agreement or a waiver or consent under this Agreement.

Section 5.04.Services as Servicer. In addition to (and not in limitation of) the provision of Section ‎5.01, Seller shall perform the following services on behalf of Purchaser:

(a)review all written documents, notices and other written communications under any Covered Agreement and provide such copies to Administrative Agent as are required under the Loan Agreement, together with any responses as Purchaser is required to provide in respect thereof;

(b)monitor the performance of any Covered Agreement Counterparty under any Covered Agreement, and take such actions as may be necessary to enforce the rights of Purchaser thereunder and collect amounts due to Purchaser thereunder, on behalf of Purchaser, and procure and supervise the services of any third parties necessary or appropriate in connection with the monitoring, enforcement, collection and remittance of the proceeds of the Transferred Assets;

(c)maintain each of the Operating Account, Collection Account and Interest Reserve Accounts in accordance with Purchaser’s obligations under the Loan Agreement and the Control Agreements, and maintain and enforce the instructions to Roche to pay amounts due to Purchaser under the Covered Agreements;

(d)cause Purchaser to maintain its organizational existence by filing all returns required in its jurisdiction of organization, and providing for its general administrative needs and overhead relating to the Transferred Assets, subject to Section 9.01 of the Loan Agreement and its Organizational Documents;

(e)identify and forward as required under the Loan Agreement any payments that are to be made to a Collection Account but when made are made to Purchaser, Seller or any misdirected account, and in consultation with Administrative Agent, effect the transfer thereof as required under the Loan Agreement; and

(f)make on behalf of Purchaser any security filings or other actions required to perfect or ensure the continued perfection of Purchaser’s rights in the Transferred Assets and Administrative Agent’s rights in Collateral.

In performing as Servicer, Seller shall not instruct any Covered Agreement Counterparty or any other Person to pay amounts in respect of the Transferred Assets to any account other than the Collection Account

required under the Loan Agreement or cause any such payments to be paid to any account other than such Collection Account.

Section 5.05.Replacement Servicer. Seller may be terminated as Servicer hereunder and replaced with a new Servicer by Purchaser (or by Administrative Agent on behalf of Purchaser in the event that Purchaser shall fail to replace the Servicer within five (5) Business Days after a Servicer Termination Event, or in the event that an Event of Default has occurred and is continuing) following the occurrence of any of the following events (each, a “Servicer Termination Event”):

(a)Seller fails to perform or observe any covenant or agreement contained in this Article V and, solely if the consequences of the failure to perform or observe such covenant or agreement can be cured, in the case of any covenant or agreement contained in Sections 5.04(d), (e) or (f), such failure continues for a period of [***] Business Days without such cure after the earlier of (x) the date Seller becomes aware of such failure and (y) the date Purchaser, or Administrative Agent on behalf of Purchaser, provides notice of such failure to Seller;

(b)an Insolvency Event of Seller; or

(c)a Seller Event of Default shall occur and be continuing.

Termination of Seller as Servicer hereunder shall be without prejudice to any rights of Purchaser or Administrative Agent that may have accrued through such date. In the event that Seller is terminated as Servicer, (i) a replacement Servicer shall be appointed by Purchaser in consultation with, and with the prior written consent of, Administrative Agent, or by Administrative Agent on behalf of Purchaser as provided in the first sentence of this Section ‎5.05) and (ii) Seller shall cooperate reasonably with Purchaser and Administrative Agent and any replacement Servicer designated by Purchaser or Administrative Agent, to transfer any information and materials to such replacement Servicer or undertake any other reasonable and necessary actions to ensure an effective transition of services required in the servicing of the Transferred Assets to the successor Servicer.

Section 6.02.Effect of Termination. No termination or rejection or failure to assume the executory obligations of this Agreement in the bankruptcy of Seller or Purchaser shall be deemed to impair or affect the obligations pertaining to any executed conveyance or executed obligations, including without limitation breaches of representations and warranties by Seller or Purchaser occurring prior to the date of such termination.

Section 6.03.Survival. Notwithstanding Section ‎6.01 hereof, the obligations of Seller contained in Article ‎VII , Article VIII and this Section ‎6.03 (Survival) shall survive the termination of this Agreement and Payment in Full.

Article VII.

INDEMNIFICATION PAYMENTS

Section 7.01.Indemnification.

(a)Seller agrees to indemnify and hold harmless Purchaser, Administrative Agent and Lenders and their respective officers, directors, members, partners, employees and agents (each, an “Indemnified Party”) against any and all liabilities, losses, damages, penalties, costs and expenses (including reasonable and documented, out of pocket costs of defense and legal fees and expenses) (“Losses”) which may be incurred or suffered by such Indemnified Party (except to the extent caused by the gross negligence or willful misconduct of the Indemnified Party) awarded against, or incurred or suffered by, such Indemnified Party, whether or not involving a third party claim, demand, action, suit or proceeding, arising out of (i) the failure of any representation, warranty or certification of Seller in the Transaction Documents or any certificate given by Seller pursuant to any of the Transaction Documents, to be true when made; (ii) a breach of any covenant by Seller set forth in, or failure by Seller to perform its duties under or otherwise comply with, the Transaction Documents (whether or not a Seller Event of Default or Servicer Termination Event), or Seller’s engaging in intentional misconduct, bad faith or negligence in the performance of such duties; or (iii) the transfer by Seller of any interest in the Transferred Assets to any Person other than Purchaser, or any attempt by any Person to void the transfer of the Transferred Assets to Purchaser.

It is the intention of the parties hereto that the above indemnities shall not be interpreted to provide indemnification for any damages, losses or costs that have the effect of recourse for non-payment or insufficient payment under the Transferred Assets and factors affecting the performance of the Transferred Assets and payments generated thereby that are not specifically represented, warranted or agreed to in the Transaction Documents which may include but are not limited to product obsolescence, competition, changes in government healthcare policies or other healthcare provider reimbursement, and withholding taxes related to the Transferred Assets. This ‎Section 7.01(a) shall not apply to Taxes other than any Taxes that represent losses, claims, damages, etc. arising from any non-Tax claim.

(b)The provisions of this indemnity shall run directly to, and be enforceable by, an injured party and shall survive the termination of this Agreement. Without limiting the foregoing or ‎Section 8.05 hereof, Purchaser’s rights under this Section ‎7.01 shall be assignable by Purchaser on a non-exclusive basis to Administrative Agent pursuant to the terms of the Loan Agreement and the Security Agreement.

(c)If any claim, demand, action or proceeding (including any investigation by any Governmental Authority) shall be brought or alleged against an Indemnified Party in respect of which indemnity is to be sought pursuant to this Section, the Indemnified Party shall, promptly after receipt of notice of the commencement of any such claim, demand, action or proceeding, notify Seller in writing of the commencement of such claim, demand, action or proceeding, enclosing a copy of all papers served, if any; provided, that the omission to so notify Seller will not relieve Seller from any liability that it may have to any Indemnified Party under this Section ‎7.01(c) unless, and only to the extent that, Seller is actually materially prejudiced by such omission. In case any such action is brought against an Indemnified Party and it notifies Seller of the commencement thereof, Seller will be entitled, at Seller’s sole cost and expense, to participate therein and, to the extent that it may wish, to assume the defense thereof, with counsel reasonably satisfactory to such Indemnified Party (who shall not, except with the consent of the Indemnified Party, be counsel to Seller), and, after notice from Seller to such Indemnified Party of its election so to assume the defense thereof, Seller will not be liable to such Indemnified Party under this Section for any legal or other expenses subsequently incurred by such Indemnified Party in connection with the defense thereof other than reasonable costs of investigation. In any such proceeding, an Indemnified Party shall

have the right to retain its own counsel, but the reasonable fees and expenses of such counsel shall be at the expense of such Indemnified Party unless (a) Seller and the Indemnified Party shall have mutually agreed to the retention of such counsel, (b) Seller has assumed the defense of such proceeding and has failed within a reasonable time to retain counsel or (c) the named parties to any such proceeding (including any impleaded parties) include both Seller and the Indemnified Party and representation of both parties by the same counsel would be inappropriate due to actual or potential conflicts of interests between them. It is agreed that Seller shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the reasonable fees and expenses of more than one separate law firm (in addition to local counsel where necessary) for all such Indemnified Parties. Seller shall not be liable for any settlement of any proceeding effected without its written consent, but, if settled with such consent or if there be a final judgment for the plaintiff, Seller agrees to indemnify the Indemnified Party from and against any Losses by reason of such settlement or judgment. Seller shall not, without the prior written consent of the Indemnified Party, effect any settlement, compromise or discharge of any claim or pending or threatened proceeding in respect of which any Indemnified Party is or could have been a party and indemnity could have been sought hereunder by such Indemnified Party, unless such settlement, compromise or discharge, as the case may be, (i) includes an unconditional written release of such Indemnified Party from all liability on claims that are the subject matter of such claim or proceeding, (ii) does not include any statement as to an admission of fault, culpability or failure to act by or on behalf of any Indemnified Party and (iii) does not impose any continuing material obligation or restrictions on any Indemnified Party.

Article VIII.
