(a) Confidentiality. Purchaser shall keep confidential and not disclose to any Person (other than its Affiliates and its and its Affiliates’ Representatives) and shall cause its Affiliates and its and its Affiliates’ Representatives to keep confidential and not disclose to any Person, any Confidential Information (as defined below). Purchaser shall, and shall cause its Affiliates and its and its Affiliates’ Representatives to, use the Confidential Information solely in connection with Purchaser’s administration of the Transaction Documents (and not for any other purpose). The foregoing obligations shall continue until the later of (x) the first anniversary of the Termination Date (as defined below) of this Agreement and (y) the date of expiration of the confidentiality obligations of Seller under the License Agreement. For purposes of this Section 6.9, the term “Representatives”, when used with respect to Purchaser, also includes the existing and prospective lenders of Purchaser and its Affiliates, but only as long as such existing and prospective lenders have agreed to be bound by the provisions of this Section 6.9 or are otherwise subject to restrictions of confidentiality that are at least as restrictive as those set forth in this Section 6.9.

25

(b) Confidential Information. “Confidential Information” means, collectively, all information (whether written or oral, or in electronic or other form, and whether furnished before, on or after the date of this Agreement) concerning, or relating in any way, directly or indirectly, to Seller, Seller’s Affiliates, this Agreement, the License Agreement, the Relevant Products or the Receivables, including (i) this Agreement, the License Agreement and any license, sublicense or other agreements involving or relating in any way, directly or indirectly, to the Receivables or the intellectual property, compounds or products giving rise to the Receivables, whether or not such licenses, sublicenses or other agreements currently exist, are executed after the date hereof, or have been previously terminated, and including all terms and conditions hereof and thereof and the identities of the parties thereto, (ii) any Royalty Reports, Modifications, assignments, notices, requests, correspondence, documents or other information furnished pursuant to this Agreement (including this Article VI) and any other reports, data, information, materials, notices, correspondence or documents of any kind relating in any way, directly or indirectly, to Seller, Seller’s Affiliates, this Agreement, the License Agreement, the Relevant Products, the Receivables or the intellectual property, compounds or products giving rise to the Receivables, and including reports, data, information, materials, notices, correspondence or documents of any kind delivered pursuant to or under this Agreement or any of the other agreements referred to in the immediately preceding clause (i), and (iii) any inventions, devices, improvements, formulations, discoveries, compositions, ingredients, patents, patent applications, know-how, processes, trial results, research, developments or other intellectual property, trade secrets or information involving or relating in any way, directly or indirectly, to the Receivables or the compounds or products giving rise to the Receivables. Notwithstanding the foregoing, “Confidential Information” shall not include any information that (A) was known by Purchaser on a non-confidential basis at the time such information was disclosed to Purchaser, its Affiliates or its or its Affiliates’ Representatives in accordance herewith or in accordance with the Confidentiality Agreement (as defined below), as evidenced by its written records or other competent evidence; (B) was or becomes generally available to the public (other than as a result of a disclosure by Purchaser, its Affiliates or its or its Affiliates’ Representatives in violation of this Agreement or the Confidentiality Agreement); (C) became or becomes known to Purchaser, its Affiliates or its or its Affiliates’ Representatives on a non-confidential basis from a source other than Seller, its Affiliates and its and its Affiliates’ Representatives (and without any breach of this Agreement or the Confidentiality Agreement by Purchaser, its Affiliates or its or its Affiliates’ Representatives); provided that Purchaser had no reason to believe that such source did not have the right to disclose such information to Purchaser, its Affiliates or its or its Affiliates’ Representatives, as the case may be (without breaching any legal, contractual or fiduciary obligation to Seller, the Licensee or any of their respective Affiliates); or (D) is or has been independently developed by Purchaser, its Affiliates or its or its Affiliates’ Representatives without use of or reference to the Confidential Information, as evidenced by its written records or other competent evidence.

26

(c) Permitted Disclosures. In the event that Purchaser or its Affiliates or any of its or its Affiliates’ Representatives are requested by a governmental or regulatory or self-regulatory authority or required by applicable Law, regulation or legal process (including the regulations of a stock exchange or governmental or regulatory or self-regulatory authority or the order or ruling of a court, administrative agency or other government or regulatory body of competent jurisdiction) to disclose any Confidential Information, Purchaser shall promptly, to the extent permitted by Law, notify Seller in writing of such request or requirement so that Seller may seek an appropriate protective order or other appropriate remedy (and if Seller seeks such an order or other remedy, Purchaser will provide such cooperation, at Seller’s sole expense, as Seller shall reasonably request). If no such protective order or other remedy is obtained and Purchaser or its Affiliates or its or its Affiliates’ Representatives are, in the view of their respective counsel (which may include their respective internal counsel), legally required to disclose Confidential Information, Purchaser or its Affiliates or its or its Affiliates’ Representatives, as the case may be, shall only disclose that portion of the Confidential Information that their respective counsel advises that Purchaser or its Affiliates or its or its Affiliates’ Representatives, as the case may be, are required to disclose and will exercise commercially reasonable efforts, at Seller’s sole expense, to obtain reliable assurance that confidential treatment will be accorded to that portion of the Confidential Information that is being disclosed. In any event, Purchaser will not oppose action by Seller to obtain an appropriate protective order or other reliable assurance that confidential treatment will be accorded the Confidential Information. Notwithstanding the foregoing, notice to Seller shall not be required where disclosure is made (i) in response to a request by a governmental or regulatory authority having competent jurisdiction over Purchaser, its Affiliates or its or its Affiliates’ Representatives, as the case may be, or (ii) in connection with a routine examination by a regulatory or self-regulatory examiner, where in each case of the immediately preceding clauses (i) and (ii), such request or examination does not expressly reference Seller, its Affiliates, the Receivables or this Agreement.

(d) Financial Statements. Notwithstanding anything herein to the contrary, nothing in this Section 6.9 shall be construed to restrict Purchaser from (i) including disclosure of the Purchase Price and the amount and nature of the Purchased Receivables in the footnotes to Purchaser’s audited annual financial statements, to the extent so required by Purchaser’s independent accountants, or including comparable disclosure in Purchaser’s unaudited quarterly financial statements, or (ii) providing copies of such audited annual and unaudited quarterly financial statements to Purchaser’s existing or prospective lenders or direct or indirect beneficial owners, as long as such lenders or beneficial owners have agreed to be bound by the provisions of this Section 6.9 or are otherwise subject to reasonable restrictions of confidentiality.

(e) Termination of Confidentiality Agreement. Effective upon the date hereof, the Confidentiality Agreement, dated [***] (the “Confidentiality Agreement”), between Seller and Purchaser shall terminate and be of no further force or effect, and shall be superseded by the provisions of this Section 6.9 (it being understood and agreed that this Section 6.9 shall apply to all Confidential Information furnished prior to the date of this Agreement).

(f) Specific Enforcement. Purchaser acknowledges and agrees that remedies at law may not be adequate to protect Seller against any actual or threatened breach of this Section 6.9 by Purchaser, its Affiliates or its or its Affiliates’ Representatives, and that Seller shall be entitled to seek specific performance and temporary and permanent injunctive relief or other equitable relief as a remedy for any such actual or threatened breach. Such remedy shall not be deemed to be the exclusive remedy for breach of this Section 6.9 but shall be in addition to all other rights and remedies available at law or equity to Seller.

(c) Notwithstanding the foregoing, any party hereto may, without the consent of the other party hereto, make public disclosures of any information with respect to this Agreement or the subject matter hereof which is the same as the information that has already been publicly disclosed by such party, or the other party hereto, in compliance with the foregoing provisions of this Section 6.10.

(d) Except as contemplated by Section 6.10(c) with respect to identifying Seller, it is understood and agreed that Purchaser shall not, without Seller’s prior written consent, identify Seller, its Affiliates or its or its Affiliates’ directors, officers, employees or agents in any advertising, press releases, sales literature or other promotional materials to be disseminated to any Person other than to Purchaser, its Affiliates and its and its Affiliates’ Representatives and investors (and potential investors). Except as contemplated by Section 6.10(c) with respect to identifying Purchaser, it is understood and agreed that Seller shall not, without Purchaser’s prior written consent, identify Purchaser, its Affiliates or its or its Affiliates’ directors, officers, employees or agents in any advertising, press releases, sales literature or other promotional materials to be disseminated to any Person other than to Seller, its Affiliates and its and its Affiliates’ Representatives and investors (and potential investors).

28

Section 6.11 Tax Matters.

(a) Seller and Purchaser agree that for United States federal income tax purposes and, to the extent applicable, U.S. state, local, non-income and non-U.S. tax purposes, the transactions contemplated by this Agreement are intended to be treated as a sale. The parties shall file tax returns consistent with the foregoing and shall not take a position inconsistent with the foregoing unless required pursuant to a “determination” that is final within the meaning of Section 1313 of the Code. If there is an inquiry by any taxing authority of Seller or Purchaser related to matters addressed in this Section 6.11 (Tax Matters), the parties shall cooperate with each other in responding to such inquiry in a reasonable manner consistent with this Section 6.11 (Tax Matters).

(b) Purchaser agrees (i) to notify Seller and the Escrow Agent in writing as soon as practicable, but in any event [***] prior to the next payment of any Purchased Receivables or other amount due to Purchaser hereunder, if (A) Purchaser becomes ineligible to use or deliver any Applicable Withholding Certificate or other tax form previously delivered pursuant to this Agreement, or (B) any Applicable Withholding Certificate, other tax form or information furnished in connection therewith or with this Agreement that was previously delivered pursuant to this Agreement ceases to be accurate or complete, and (ii) to the extent it is legally eligible to do so, to provide to Seller and the Escrow Agent any additional tax forms or information relating to any Applicable Withholding Certificate (A) upon reasonable request by Seller or the Escrow Agent and (B) subject to clause (b)(i)(A) of this Section 6.11, promptly upon any Applicable Withholding Certificate or other tax form previously delivered pursuant to this Agreement becoming obsolete. Purchaser agrees to notify each of Seller and the Escrow Agent as soon as practicable, but in any event [***] prior to the next payment of any Purchased Receivables or other amount due to Purchaser hereunder, if the statements in Section 5.10 (if made as of any date after the Closing Date) cease, or because of any change of Law, any omission by Purchaser or any act planned or performed by Purchaser, would in the future cease, to be true.

(c) All payments to Purchaser under this Agreement shall be made without any deduction or withholding for or on account of any tax, provided that, if Seller reasonably determines in consultation with Purchaser that deduction or withholding of any tax has become required from any amount payable hereunder (but for this sentence) to Purchaser, then Seller shall be entitled to deduct (or cause to be deducted) such tax prior to remittance to Purchaser, provided, further, that Seller shall provide reasonable advance notice to Purchaser of its intention to withhold and shall provide Purchaser a reasonable opportunity to take (with Seller’s cooperation) any measures that could reduce or eliminate the amount of such withholding. Seller shall remit (or cause to be remitted) any amount withheld or deducted pursuant to this Section 6.11 (Tax Matters) to the relevant taxing authority, and any amount so remitted shall be treated as paid hereunder to Purchaser. Seller shall use commercially reasonable efforts to give or cause to be given to Purchaser such assistance and such information concerning the reasons for deduction as may be reasonably necessary to enable Purchaser to claim appropriate exemption therefrom, or credit therefor, and, in each case, shall furnish Purchaser with proper evidence of the taxes withheld and remitted to the relevant taxing authority.

29

Section 6.12 Further Actions. From and after the Closing, each of Purchaser and Seller shall, at the expense of the requesting party, execute and deliver such additional documents (including the Specified Financing Statements, other financing statements and continuation statements in respect thereof), certificates and instruments, and perform such additional acts, as may be reasonably requested and necessary or appropriate to carry out all of the provisions of this Agreement and to give full effect to and consummate the transactions contemplated by this Agreement.

Section 7.2 Procedures Relating to Indemnification for Third Party Claims.

(a) Notice of Third Party Claim. In order for a party (an “Indemnified Party”) to be entitled to any indemnification under this Article VII in respect of Losses arising out of or involving a claim or demand made by any Person other than Purchaser or Seller against a Purchaser Indemnified Party or a Seller Indemnified Party, as applicable (a “Third Party Claim”), the Indemnified Party must, promptly after its receipt of notice of the commencement of such Third Party Claim, notify the party from whom indemnification is sought under this Article VII (the “Indemnifying Party”) in writing (including in such notice a brief description of such Third Party Claim, including damages sought or estimated, to the extent actually known or reasonably capable of estimation by the Indemnified Party); provided, however, that the failure to promptly provide such notice shall not affect the indemnification provided under this Article VII except to the extent that the Indemnifying Party has been actually prejudiced as a result of such failure. Thereafter, the Indemnified Party shall deliver to the Indemnifying Party, promptly after the Indemnified Party’s receipt thereof, copies of all documents (including court papers) received by the Indemnified Party relating to such Third Party Claim.

(b) Defense of Third Party Claims. The Indemnifying Party shall be entitled to participate in the defense of any Third Party Claim and, if it so chooses, to assume the defense thereof, at its own expense, with counsel selected by the Indemnifying Party; provided, that such counsel is not reasonably objected to by the Indemnified Party. If the Indemnifying Party elects to assume the defense of any Third Party Claim, the Indemnifying Party shall not be liable to the Indemnified Party for legal expenses subsequently incurred by the Indemnified Party in connection with the defense thereof, except that, if the Indemnifying Party and the Indemnified Party have conflicting interests or different defenses available with respect to such Third Party Claim, the Indemnified Party may hire its own separate counsel (provided that such counsel is not reasonably objected to by the Indemnifying Party) with respect to such Third Party Claim and the related action or suit, and the reasonable fees and expenses of such counsel shall be considered Losses for purposes of this Agreement. If the Indemnifying Party elects to assume the defense of any Third Party Claim, the Indemnifying Party shall permit the Indemnified Party to participate in, but not control, the defense of such Third Party Claim through counsel chosen by the Indemnified Party, provided that such counsel is not reasonably objected to by the Indemnifying Party and, except in the circumstances described in the immediately preceding sentence, the fees and expenses of such counsel shall be borne by the Indemnified Party. The Indemnifying Party shall be liable for the reasonable fees and expenses of counsel employed by the Indemnified Party in the defense of a Third Party Claim (which shall all be considered Losses for purposes of this Agreement) for any period during which the Indemnifying Party has not assumed the defense thereof (other than during the period prior to the time the Indemnified Party shall have notified the Indemnifying Party of such Third Party Claim).

(c) Cooperation. The parties hereto shall cooperate in the defense or prosecution of any Third Party Claim, with such cooperation to include (i) the retention of and the provision to the Indemnifying Party of records and information that are reasonably relevant to such Third Party Claim and (ii) the making available of employees on a mutually convenient basis for providing additional information and explanation of any material provided hereunder. If the Indemnifying Party shall have assumed the defense of a Third Party Claim, the Indemnified Party shall agree to any settlement, compromise or discharge of such Third Party Claim that the

35

Indemnifying Party may recommend and that by its terms obligates the Indemnifying Party to pay the full amount of the liability (if any) in connection with such Third Party Claim and which does not impose any non-monetary penalties on the Indemnified Party and releases the Indemnified Party completely and unconditionally in connection with such Third Party Claim. Regardless of whether the Indemnifying Party shall have assumed the defense of a Third Party Claim, the Indemnified Party shall not be entitled to be indemnified or held harmless pursuant to this Article VII if the Indemnified Party shall settle such Third Party Claim without the prior written consent of the Indemnifying Party (such consent not to be unreasonably withheld, delayed or conditioned).

Section 7.3 Procedures Relating to Indemnification for Other Claims. In order for an Indemnified Party to be entitled to any indemnification under this Article VII in respect of Losses that do not arise out of or involve a Third Party Claim, the Indemnified Party must notify the Indemnifying Party promptly in writing (including in such notice a brief description of the claim for indemnification and the Loss, including damages sought or estimated, to the extent actually known or reasonably capable of estimation by the Indemnified Party); provided, however, that the failure to promptly provide such notice shall not affect the indemnification provided under this Article VII except to the extent that the Indemnifying Party has been actually prejudiced as a result of such failure.

Section 7.4 Limitations on Indemnification.

(a) Seller. Notwithstanding anything in this Agreement to the contrary, Seller shall not have any liability under clause (i) of Section 7.1(a):

(i) with respect to any individual item (or any series of related items) if the Loss related thereto is less than $[***];

(ii) unless the aggregate liability for all Losses suffered by the Purchaser Indemnified Parties thereunder exceeds $[***], in which case Seller shall pay [***]; or

(iii) on any day on which such indemnity claim under clause (i) of Section 7.1(a) is paid by Seller, in excess of the Cap Amount for such day. “Cap Amount” means, for any day on which an indemnity claim under clause (i) of Section 7.1(a) is paid by Seller, the excess of (x) the Purchase Price over (y) the sum of (A) the aggregate amount of Purchased Receivables received by Purchaser on or prior to such day after deducting the amount of such Purchased Receivables that has been actually repaid by Purchaser on or prior to such day pursuant to Section 6.2(d) and (B) the aggregate amount of payments made under clause (i) of Section 7.1(a) by Seller on or prior to such day.

(b) Purchaser. Notwithstanding anything in this Agreement to the contrary, Purchaser shall not have any liability under clause (i) of Section 7.1(b):

(i) with respect to any individual item (or any series of related items) if the Loss related thereto is less than $[***];

Purchaser further acknowledges and agrees that (A) as between the parties hereto, Purchaser is assuming all market risk associated with MAVYRET and any other Relevant Products and, as such, shall have no recourse against Seller or any of Seller’s Affiliates based on the failure of the sales of MAVYRET or any other Relevant Product to meet its or any other Person’s projections, and (B) neither Seller nor any of Seller’s Affiliates guarantees any obligations of the Licensee under the License Agreement.

37

Section 7.7 Exclusive Remedy. Other than for breaches of any covenants or agreements set forth in Section 6.9 or Article VIII, the parties hereto acknowledge and agree that, from and after the Closing, this Article VII (including Section 7.4 and Section 7.5) shall provide such parties’ sole and exclusive remedy with respect to any matter or claim arising out of, relating to or in connection with any of the Transaction Documents or any of the transactions contemplated thereby and, without limiting the foregoing, neither party shall be entitled to rescind this Agreement, except that any such claim or matter based upon fraud, deliberate or willful breach of covenant or willful misconduct shall not be subject to or limited by this Article VII.

For greater certainty, (a) nothing in this Section 7.8 shall have the effect of precluding the recovery of Losses incurred by a Purchaser Indemnified Party to the extent such Losses constitute Purchased Receivables under this Agreement, notwithstanding that the loss of a receivable or a payment in the nature of the Purchased Receivables might otherwise be characterized as a pure economic loss, and (b) Purchaser shall be entitled to make indemnification claims, in accordance with the procedures set forth in this Article VII, for Losses incurred by a Purchaser Indemnified Party to the extent such Losses constitute any portion of the Purchased Receivables that Purchaser was or would have been entitled to receive but did not receive timely or at all due to any indemnifiable events under this Agreement, and such portion of the Purchased Receivables shall not be deemed special, indirect, incidental, exemplary, punitive, multiple or consequential damages for any purpose of this Agreement.
