(e)Notwithstanding that the Seller and the Purchaser expressly intend for the sale, contribution, assignment, transfer, conveyance and granting of the Vifor Royalties to be a true, complete, absolute and irrevocable sale and assignment, the Seller shall, on the First Milestone Closing Date, assign, convey, grant and pledge to the Purchaser, as security for its obligations created hereunder in the event that the transfer of the Vifor Royalties contemplated by this Purchase and Sale Agreement is held not to be a sale, a first priority security interest in and to all of the Seller’s right, title and interest in, to and under the Vifor Royalties and, in such event, this Purchase and Sale Agreement shall constitute a security agreement.

Section 2.4Prepayment.  At any time, the Seller shall have the right, but not the obligation, to pay to the Purchaser the Maximum Hard Cap Amount less the Total Net Amount as of such date, by wire transfer of immediately available funds to an account designated in writing by the Purchaser, and upon such payment, no further payments of the Purchased Royalties are due to the Purchaser hereunder and the Royalty Termination Date shall be deemed to have occurred.

40


Section 7.2Indemnification by the Purchaser.  The Purchaser agrees to indemnify and hold each of the Seller and its Affiliates and any or all of their respective partners, directors, officers, managers, members, employees, agents and controlling Persons (each, a “Seller Indemnified Party”) harmless from and against, and will pay to each Seller Indemnified Party the amount of, any and all Losses awarded against or incurred or suffered by such Seller Indemnified Party, whether or not involving a Third Party Claim, arising out of (a) any breach of any representation or warranty made by the Purchaser in any of the Transaction Documents or any certificate delivered by the Purchaser to the Seller in writing pursuant to this Purchase and Sale Agreement, (b) any breach of or default under any covenant or agreement of the Purchaser in any Transaction Document to which the Purchaser is a party or (c) any brokerage or finder’s fees or commissions or similar amounts incurred or owed by the Purchaser to any brokers, financial advisors or comparable other Persons retained or employed by it in connection with the transactions contemplated by this Purchase and Sale Agreement.  Any amounts due to any Seller Indemnified Party hereunder shall be payable by the Purchaser to such Seller Indemnified Party upon demand.

Section 7.3Procedures for Third Party Claims.  If any Third Party Claim shall be brought or alleged against an indemnified party in respect of which indemnity is to be sought against an indemnifying party pursuant to Section 7.1 or Section 7.2, the indemnified party shall, promptly after receipt of notice of the commencement of such Third Party Claim, notify the indemnifying party in writing of the commencement thereof, enclosing a copy of all papers served, if any; provided that the omission to so notify such indemnifying party will not relieve the indemnifying party from any liability that it may have to any indemnified party under Section 7.1 or Section 7.2 unless, and only to the extent that, the indemnifying party is actually prejudiced by such omission.  In the event that any Third Party Claim is brought against an indemnified party and it notifies the indemnifying party of the commencement thereof in accordance with this Section 7.3, the indemnifying party will be entitled, at the indemnifying party’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 the indemnifying party), and, after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party will not be liable to such indemnified party under this ARTICLE VII 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 Third Party Claim, 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 sole cost and expense of such indemnified party unless (a) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel, (b) the indemnifying party has assumed the defense of such proceeding and has failed within a reasonable time to retain counsel reasonably satisfactory to such indemnified party or (c) the named parties to any such Third Party Claim (including any impleaded parties) include both the indemnifying party 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 based on the advice of counsel to the indemnified party.  It is agreed that the indemnifying party shall not, in connection with any Third Party Claim 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.  The indemnifying party shall not be liable for any settlement of any Third Party Claim effected without its written consent, but, if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any Loss by reason of such settlement or judgment.  No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement, compromise or discharge of any pending or threatened Third Party Claim in respect of which any indemnified party is or could have been a party and indemnity could be sought hereunder by such indemnified party, unless such settlement, compromise or discharge, as the case may be, (i) includes an unconditional, full written release of such indemnified party, in form and substance reasonably satisfactory to the 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

41


by or on behalf of any indemnified party and (iii) does not impose any continuing obligations or restrictions other than customary and reasonable confidentiality obligations relating to such claim, settlement or compromise.

Section 7.4Other Claims.  A claim by an indemnified party under this ARTICLE VII for any matter not involving a Third Party Claim and in respect of which such indemnified party would be entitled to indemnification hereunder may be made by delivering, in good faith, a written notice of demand to the indemnifying party, which notice shall contain (a) a description and the amount of any Losses incurred or suffered or reasonably expected to be incurred or suffered by the indemnified party, (b) a statement that the indemnified party is entitled to indemnification under this ARTICLE VII for such Losses and a reasonable explanation of the basis therefor, and (c) a demand for payment in the amount of such Losses.  For all purposes of this Section 7.4, the Seller shall be entitled to deliver such notice of demand to the Purchaser on behalf of the Seller Indemnified Parties, and the Purchaser shall be entitled to deliver such notice of demand to the Seller on behalf of the Purchaser Indemnified Parties.

Section 7.5Survival.  All representations, warranties and covenants made in this Purchase and Sale Agreement, in any other Transaction Document or in any certificate delivered pursuant to this Purchase and Sale Agreement shall survive the execution and delivery of this Purchase and Sale Agreement and the Closing.  The rights hereunder to indemnification, payment of Losses or other remedies based on any such representation, warranty or covenant shall not be affected by any investigation conducted with respect to, or any knowledge acquired (or capable of being acquired) at any time (whether before or after the execution and delivery of this Purchase and Sale Agreement or the Closing) in respect of the accuracy or inaccuracy of or compliance with, any such representation, warranty or covenant.

Section 7.6Remedies.  Except in the case of actual fraud, intentional misrepresentation, intentional wrongful acts, intentional breach, bad faith or willful misconduct and except as set forth in Section 10.2 or in the other Transaction Documents, (a) the indemnification afforded by this ARTICLE VII shall be the sole and exclusive remedy for any and all Losses awarded against or incurred or suffered by a Party in connection with any breach of any representation or warranty made by a Party in any of the Transaction Documents or any certificate delivered by a Party to the other Party in writing pursuant to this Purchase and Sale Agreement or any breach of or default under any covenant or agreement by a Party pursuant to any Transaction Document and (b) the Purchaser acknowledges and agrees that the Purchaser, together with its Affiliates and representatives, has made its own investigation of the Purchased Royalties and the Transferred Assets and the transactions contemplated by the Transaction Documents and is not relying on, and shall have no remedies in respect of, any implied warranties or upon any representation or warranty whatsoever as to the future amount or potential amount of the Purchased Royalties, or as to the creditworthiness of any Counterparty (or any of their respective Affiliates).

Section 7.7Limitations.  Notwithstanding anything in this Purchase and Sale Agreement to the contrary, (a) in no event shall any Seller Indemnified Party or the Purchaser Indemnified Party have any liability for, or Losses be deemed to include, any special, punitive or exemplary damages, or any lost profits, whether in contract or tort, regardless of whether the other Party shall be advised, shall have reason to know, or in fact shall know of the possibility of such damages suffered or incurred by any such Seller Indemnified Party or the Purchaser Indemnified Party in connection with this Purchase and Sale Agreement any of the other Transaction Documents or any of the transactions contemplated hereby or thereby, except to the extent any such damages are actually paid to a Third Party in accordance with Section 7.3 and (b) the Seller’s aggregate liability under Section 7.1 shall in no event exceed an amount equal to (1) the Hard Cap Amount, minus (2) the Total Net Amount,  minus (3) the aggregate amount collected or received by the Purchaser (and any direct or indirect transferee of the Purchaser to whom any interest in the Purchased Royalties is transferred) pursuant to the exercise of its rights under Section 7.1 (without duplication of any amounts received pursuant to clause (2)).  Notwithstanding the foregoing, the limitations set forth in this Section 7.7

42


shall not apply to any claim for indemnification hereunder in the case of actual fraud, intentional misrepresentation, intentional wrongful acts, intentional breach, bad faith or willful misconduct. The Parties acknowledge and agree that (a) the Purchaser’s Losses, if any, for any indemnifiable events under this Purchase and Sale Agreement will typically include Losses for Purchased Royalties that the Purchaser was entitled to receive in respect of its ownership of the Purchased Royalties but did not receive timely or at all due to such indemnifiable event and (b) subject to this Section 7.7, the Purchaser shall be entitled to make indemnification claims for all such missing or delayed Purchased Royalties that the Purchaser was entitled to receive in respect of its ownership of the Purchased Royalties as Losses hereunder (which claims shall be reviewed and assessed by the Parties in accordance with the procedures set forth in this ARTICLE VII), and such missing or delayed Purchased Royalties shall not be deemed special, punitive or exemplary damages, or lost profits for any purpose of this Purchase and Sale Agreement.

Section 7.8Tax Treatment of Indemnification Payments.  For all purposes hereunder, any indemnification payments made pursuant to this ARTICLE VII will be treated as an adjustment to the Investment Amount for all Tax purposes to the fullest extent permitted by Applicable Law.

ARTICLE VIII

Section 8.1Confidentiality.  Except as provided in this ARTICLE VIII or otherwise agreed in writing by the Parties, the Parties agree that, during the term of this Purchase and Sale Agreement and until the tenth (10th) anniversary of the date of termination of this Purchase and Sale Agreement, each Party (the “Receiving Party”) shall keep confidential, and shall not publish or otherwise disclose and shall not use for any purpose other than as provided for in this Purchase and Sale Agreement (which includes the exercise of any rights or the performance of any obligations hereunder), any information (whether written or oral, or in electronic or other form) furnished to it by or on behalf of the other Party (the “Disclosing Party”) pursuant to the Existing Confidentiality Agreement or this Purchase and Sale Agreement, including the terms of this Purchase and Sale Agreement (such information, “Confidential Information” of the Disclosing Party), except for that portion of such information that:

(a)was already in the Receiving Party’s possession on a non-confidential basis prior to its disclosure to it by the Disclosing Party, or becomes known to the Receiving Party from a source other than the Disclosing Party and its representatives without any breach of this Purchase and Sale Agreement, in each case as evidenced by written records (provided that if such information was disclosed to the Receiving Party on a non-confidential basis by a source that is not the Disclosing Party, such source to the knowledge of the Receiving Party had the right to disclose such information to the Receiving Party without any legal, contractual or fiduciary obligation to, any person with respect to such information);

(b)is or becomes generally available to the public other than as a result of an act or omission by the Receiving Party or its Affiliates in breach of this Purchase and Sale Agreement; or

Section 8.3Permitted Disclosure.  In the event that the Receiving Party or its Affiliates or any of its or its Affiliates’ representatives are requested by a governmental or regulatory authority or required

43


by Applicable Law, regulation or legal process (including the regulations of a stock exchange or governmental or 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, the Receiving Party shall promptly, to the extent permitted by Applicable Law, notify the Disclosing Party in writing of such request or requirement so that the Disclosing Party may seek an appropriate protective order or other appropriate remedy (and if the Disclosing Party seeks such an order or other remedy, the Receiving Party will provide such cooperation, at the Receiving Party’s sole expense, as the Disclosing Party shall reasonably request). If no such protective order or other remedy is obtained and the Receiving Party 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, the Receiving Party 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 the Receiving Party 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 the Disclosing Party’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, the Receiving Party will not oppose action by the Disclosing Party to obtain an appropriate protective order or other reliable assurance that confidential treatment will be accorded the Confidential Information. Notwithstanding the foregoing, notice to the Disclosing Party shall not be required where disclosure is made (i) in response to a request by a governmental or regulatory authority having competent jurisdiction over the Receiving Party, its Affiliates or its or its Affiliates’ representatives, as the case may be, or (ii) in connection with a routine examination by a regulatory examiner, where in each case such request or examination does not expressly reference the Disclosing Party, its Affiliates, the Purchased Royalties or this Purchase and Sale Agreement. The Receiving Party may disclose Confidential Information to its Affiliates, its and their employees, directors, officers, contractors, agents, and representatives, and to potential or actual acquirers, merger partners, permitted assignees, investment bankers, investors, limited partners, partners, lenders, or other financing sources (including, in the case of the Seller, any party evaluating the acquisition of any portion of the Purchased Royalties that are not included in the Purchased Royalties), and their respective directors, employees, contractors and agents; provided that such person or entity agrees to confidentiality and non-use obligations with respect thereto at least as stringent as those specified for in this Article VIII. Further, notwithstanding anything contained in this Article VIII to the contrary, the Seller may disclose Confidential Information to the extent such disclosure is reasonably necessary to comply with the Securities Act of 1933, as amended, the Securities Exchange Act of 1934, as amended, or with any rule, regulation or legal process promulgated by the SEC or a stock exchange, subject to the Seller’s obligations set forth in Section 5.2.

Section 8.4Other Relevant Obligations.  In addition to, and without limiting, the Purchaser’s obligations under this Article VIII, the Purchaser shall fully comply with any confidentiality obligations of the Seller or any of its Affiliates under the Maruishi License Agreement and the Vifor License Agreement that are applicable to the Confidential Information.
