Neither the Seller nor the Purchaser intends the transactions contemplated hereby to be, or for any purpose (including U.S. federal income tax purposes) characterized as, a loan from the Purchaser to the Seller or a pledge or assignment or a security agreement. The Seller waives any right to contest or otherwise assert that this Purchase and Sale Agreement does not constitute a true, complete, absolute and irrevocable sale and assignment by the Seller to the Purchaser of the Purchased Royalties under Applicable Law, which waiver shall be enforceable against the Seller in any Bankruptcy Event in respect of the Seller. The sale, contribution, assignment, transfer, conveyance and granting of the Purchased Royalties shall be reflected on the Seller’s financial statements and other records as a sale of assets to the Purchaser (except to the extent GAAP or the rules of the SEC require otherwise with respect to the Seller’s consolidated financial statements).

(d)    Notwithstanding that the Seller and the Purchaser expressly intend for the sale, contribution, assignment, transfer, conveyance and granting of the Purchased Royalties to be a true, complete, absolute and irrevocable sale and assignment, the Seller hereby assigns, conveys, grants and pledges to the Purchaser, as security for its obligations created hereunder in the event that the transfer 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 Purchased Royalties and, in such event, this Purchase and Sale Agreement shall constitute a security agreement.

(a)    If the aggregate Purchased Royalties received by the Purchaser equal at least the Initial Cap on or prior to December 31, 2025 (such date of receipt, the “Minimum Cap Date”), (i) the Purchaser Representative and the Seller shall deliver joint written instructions to the Escrow Agent to instruct the Escrow Agent to pay the sum of the aggregate Purchased Royalties achieved for the calendar quarter during which the Minimum Cap Date occurs, less the Initial Cap (such amount the “Minimum Cap Overage”), to the Seller pursuant to the payment instructions set forth in such joint written instructions and (ii) the payment of the Purchased Royalties to the Purchaser for the calendar quarter during which the Minimum Cap Date occurs shall be reduced by such Minimum Cap Overage and no further payments of Purchased Royalties are due to the Purchaser hereunder.

If the aggregate Purchased Royalties payable to the Purchaser do not equal the Initial Cap on or prior to December 31, 2025, and the Seller is not eligible to, or does not exercise the right to, pay the Initial Cap True-Up, the Purchased Royalties shall continue to be paid to the Purchaser until such time that the aggregate Purchased Royalties paid to the Purchaser equals the Maximum Cap. At such time that the aggregate Purchased Royalties equal the Maximum Cap, no further payments of Purchased Royalties are due to the Purchaser hereunder.

(c)    At any time, the Seller shall have the right, but not the obligation, to pay to the Purchaser the Maximum Cap less the aggregate Purchased Royalties paid to the Purchaser as of such date, by wire transfer of immediately available funds to an account designated in writing by the Purchaser Representative, and upon such payment, no further payments of the Purchased Royalties are due to the Purchaser hereunder and the Royalty Cap shall be deemed to have been achieved.

The Seller shall consult and reasonably consider any comments from the Purchaser Representative with respect to such negotiation of a Baxter New Arrangement.

(c)    Without limiting the provisions of Section 6.5 or any other rights or remedies the Purchaser may have under this Purchase and Sale Agreement, if the Novo Settlement Agreement terminates, other than in violation of this Purchase and Sale Agreement, then the Seller shall have the exclusive right, following the effective date of such termination, and shall use Commercially Reasonable Efforts to negotiate a license with a Third Party under the Novo Patents for such Third Party to make, have made, use, import, offer for sale and sell the Novo Nordisk Factor IX Product for any purpose that Novo Nordisk would have been permitted to make, have made, use, import, offer for sale and sell Novo Nordisk Factor IX Product under the Novo Settlement Agreement, which license shall (i) become effective not earlier than the effective date of such termination, (ii) expire not later than the last day of the Novo Royalty Term (for purposes of this clause (ii), the Novo Royalty Term shall be determined assuming that the Novo Settlement Agreement had not been terminated) and (iii) include terms, conditions and limitations that are not materially less favorable to the Seller, taking into account the sale of the Purchased Royalties pursuant to the Transaction Documents, than those contained in the Novo Settlement Agreement, including with respect to obligations and costs imposed on the Seller, disclaimers of the Seller’s liability, intellectual property ownership and control and indemnification of the Seller (any such license, a “Novo New Arrangement”).

Section 6.7     Audits

32

[***] Certain information in this document has been omitted from this exhibit because it is both (i) not material and (ii) would be competitively harmful if publicly disclosed.

(a)    The Seller shall not, without first consulting the Purchaser Representative, cause an inspection or audit of any Counterparty’s books and records to be conducted pursuant to and in accordance with Section 10.2 of the Baxter License Agreement, Section 7.14 of the AZ License Agreement, Section 6(c)(iv) of the Novo Settlement Agreement or Section 3.9 of the Novo Sublicense Agreement, as the case may be. From time to time, but not more frequently than once per calendar year, the Purchaser Representative may request the Seller to, and the Seller shall, cause an inspection or audit of any Counterparty’s books and records in respect of the Purchased Royalties to be conducted pursuant to and in accordance with Section 10.2 of the Baxter License Agreement, Section 7.14 of the AZ License Agreement, Section 6(c)(iv) of the Novo Settlement Agreement or Section 3.9 of the Novo Sublicense Agreement, as the case may be. The Seller shall retain the exclusive right to inspect and audit each Counterparty’s books and records at any time and from time to time at its sole discretion for payments relating to periods prior to the Royalties Commencement Date (any such audit, a “Past Period Audit”). For the purposes of exercising the Purchaser Representative’s rights pursuant to this Section 6.7(a) in respect of the Baxter License Agreement, the AZ License Agreement or the Novo Sublicense Agreement, the Seller shall appoint such public accounting firm of nationally recognized standing as the Purchaser Representative shall select for such purpose (it being understood and agreed that any such public accounting firm shall, pursuant to Section 10.2 of the Baxter License Agreement, Section 7.14 of the AZ License Agreement or Section 3.9 of the Novo Sublicense Agreement, be reasonably acceptable to Baxter or AZ, respectively). For the purposes of exercising the Purchaser Representative’s rights pursuant to this Section 6.7(a) in respect of the Novo Settlement Agreement, the Seller shall appoint such public accounting firm(s) as the Purchaser Representative shall select from the list set forth in Section 6(c)(iv) of the Novo Settlement Agreement. The Seller and the Purchaser Representative agree that all of the expenses of, and amounts payable to AZ, Baxter or Novo Nordisk, as the case may be, as a result of any inspection or audit carried out at the request of the Purchaser Representative pursuant to this Section 6.7(a) that would otherwise be borne by the Seller pursuant to the applicable License Agreement shall instead be borne by the Purchaser Representative and reimbursed to the Seller promptly on demand, including such reasonable fees and expenses of such public accounting firm as are to be borne by the Seller pursuant to Section 10.2 of the Baxter License Agreement, Section 7.14(b) of the AZ License Agreement, Section 6(c)(iv)(H) of the Novo Settlement Agreement or Section 3.9 of the Novo Sublicense Agreement, as the case may be, together with the Seller’s out-of-pocket costs and expenses incurred in connection with such inspection or audit; provided, that the Purchaser Representative shall be reimbursed by the Seller for any such fees and expenses to the extent the Seller is entitled to receive reimbursement from AZ, Baxter or Novo Nordisk, as the case may be; provided, further, that, for the avoidance of doubt, any audit caused by the Seller pursuant to the first sentence of this Section 6.7(a) or any Past Period Audit shall not be deemed to be carried out at the request of the Purchaser Representative and the Purchaser Representative shall have no obligation to reimburse the Seller, pursuant to this sentence, for any fees, costs or expenses incurred by the Seller in connection therewith. The Seller shall, to the extent not prohibited by obligations of confidentiality contained in the License Agreement pursuant to which an inspection or audit in respect of the Purchased Royalties is conducted, [***] furnish to the Purchaser Representative any inspection or audit report prepared in connection with such inspection or audit.

(b)    In the event that any inspection or audit conducted pursuant to Section 6.7(a) uncovers that the amounts actually paid to the Purchaser for any period in respect of the Purchased Royalties were greater than the amounts that should have been paid to the Purchaser for such period in respect of the Purchased Royalties, the Purchaser Representative shall cause the amount of such overpayment to be paid to the applicable Counterparty [***] after delivery to the Purchaser Representative, pursuant to Section 6.7(a), of the applicable inspection or audit report or certificate, as the case may be, showing such

33

[***] Certain information in this document has been omitted from this exhibit because it is both (i) not material and (ii) would be competitively harmful if publicly disclosed.

overpayment. In the event that any inspection or audit conducted pursuant to Section 6.7(a) uncovers that the amounts actually paid to the Purchaser for any period in respect of the Purchased Royalties were less than the amounts that should have been paid to the Purchaser for such period in respect of the Purchased Royalties, the Seller shall cooperate and provide assistance as reasonably requested by the Purchaser Representative to cause the amount of such underpayment to be paid to the Purchaser by the applicable Counterparty in accordance with the timeframe set forth in the applicable License Agreement promptly after delivery to the Purchaser Representative, pursuant to Section 6.7(a), of the applicable inspection or audit report or certificate, as the case may be, showing such underpayment.

Section 6.8     [***].

Section 6.9     Tax Matters.

(a)    All payments to the Purchaser under this Purchase and Sale Agreement shall be made without any deduction or withholding for or on account of any Tax unless required by Applicable Law; provided that, if deduction or withholding for or on account of any Purchaser Indemnified Tax is required by Applicable Law to be made, and is made, from any payment to Purchaser under this Purchase and Sale Agreement, then the Seller shall, [***] after such deduction or withholding is made, make a payment to the Purchaser so that, after all such required deductions and withholdings are made by any applicable withholding agent (including any deductions and withholdings required with respect to any additional payments under this Section 6.9(a)), the Purchaser receives an amount equal to the amount that it would have received had no withholding of such Purchaser Indemnified Taxes been made.

(b)    The Seller shall notify the Purchaser Representative in writing [***] following the receipt of any written notification by any Counterparty or by an Affiliate of such Counterparty that such Counterparty intends to make any Permitted Tax Withholding. The Seller shall, upon the reasonable request of the Purchaser Representative and at the Purchaser Representative’s expense, reasonably cooperate with the Purchaser Representative and use its commercially reasonable efforts to make such filings and take such other actions as may be reasonably necessary and specified by the Purchaser Representative in order to allow an exemption from or reduction of any Permitted Tax Withholding.

(c)    The Parties agree not to take any position that is inconsistent with the provisions of Section 2.1(b) on any Tax return or in any Tax audit or other administrative or judicial proceeding unless required by law. If there is an inquiry by any Governmental Authority of the Seller, the Purchaser or the Purchaser Representative related to the treatment described in Section 2.1(b), the Parties shall cooperate with each other in responding to such inquiry in a commercially reasonable manner that is consistent with Section 2.1(b).

(d)    If a Purchaser is entitled to additional amounts pursuant to Section 6.9(a), then such Purchaser shall use commercially reasonable efforts to assign its rights and obligations hereunder to an Affiliate, if, in the reasonable judgment of such Purchaser, such assignment (i) would eliminate or reduce any additional amounts payable pursuant to Section 6.9(a) in the future and (ii) would not subject such Purchaser to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Purchaser.  The Seller hereby agrees to pay all reasonable costs and expenses incurred by such Purchaser in connection with any such assignment.

Section 6.10     Existence

The Seller shall (a) preserve and maintain its existence (provided, however, that nothing in this Section 6.10 shall prohibit the Seller from entering into any merger or consolidation with, or selling or

34

[***] Certain information in this document has been omitted from this exhibit because it is both (i) not material and (ii) would be competitively harmful if publicly disclosed.

otherwise transferring all or substantially all of its assets to, any other Person if the Seller is the continuing or surviving entity or if the surviving or continuing or acquiring entity assumes (either expressly or by operation of law) all of the obligations of the Seller under the Transaction Documents), (b) preserve and maintain its rights, franchises and privileges unless failure to do any of the foregoing would not have a Material Adverse Effect, (c) qualify and remain qualified in good standing in each jurisdiction where the failure to preserve and maintain such qualifications would have a Material Adverse Effect, including appointing and employing such agents or attorneys in each jurisdiction where it shall be necessary to take action under this Purchase and Sale Agreement, and (d) comply with its organizational documents, except, in the case of this clause (d), for any non-compliance that would not have a Material Adverse Effect.

Section 6.11     Novo Consent; Baxter Consent Amendment; Licensee Confirmations

(a)    Following the Closing, the Seller shall use commercially reasonable efforts to obtain from Novo Nordisk an executed copy of the Novo Consent; provided that the Seller shall not agree to any material changes to the Novo Consent without the prior consent of the Purchaser Representative (not to be unreasonably withheld, conditioned or delayed). If the Seller shall fail to obtain and deliver to the Purchaser Representative an executed copy of the Novo Consent, then solely to the extent the Novo Settlement Royalties are not received by the Purchaser (other than by reason of breach or negligence by the Escrow Agent, or breach by the Purchaser Representative, under the Escrow Agreement), the Seller shall [***] make each payment to the Purchaser otherwise due to the Purchaser hereunder such that the Purchaser receives the full amount of such Novo Settlement Royalties that would have been payable to the Purchaser had such Novo Consent been obtained. Prior to the Seller’s delivery of, or in the event of the failure of the Seller to obtain, an executed copy of the Novo Consent, such that delivery by the Seller to the Purchaser Representative of (a) the quarterly royalty reports made pursuant to Section 6(c)(i) of the Novo Settlement Agreement or (b) material written notices, certificates, offers, proposals, correspondence, reports or other communications delivered pursuant to the Novo Settlement Agreement relating to the Novo Settlement Agreement, the Novo Patents, the Purchased Royalties or Rebinyn would constitute a breach by the Seller of its confidentiality obligations under the Novo Settlement Agreement, the Seller shall deliver to the Purchaser Representative [***], a written summary, certified by an officer of the Seller and to the extent providing such summary is not itself a Confidentiality Breach, of all information contained in such communication that Seller reasonably believes is material (a “Material Summary”). If Seller is advised in writing by its counsel that providing the Purchaser Representative such Material Summary will constitute a breach by the Seller of its confidentiality obligations (a “Confidentiality Breach”) under the Novo Settlement Agreement, then the Seller shall paraphrase or otherwise describe the substance for the Purchaser Representative of such communication to the maximum extent possible, as the Seller is advised in writing by its counsel, without causing a Confidentiality Breach under the Novo Settlement Agreement (“Permissible Summary Disclosure”).

(b)    Following the Closing, the Seller shall use commercially reasonable efforts to obtain from Baxter an executed copy of the Baxter Consent Amendment; provided that the Seller shall not agree to any material changes to the Baxter Consent Amendment without the prior consent of the Purchaser Representative (not to be unreasonably withheld, conditioned or delayed). If the Seller shall fail to obtain and deliver to the Purchaser Representative an executed copy of the Baxter Consent Amendment, then solely to the extent the Novo Sublicense Royalties are not received by the Purchaser (other than by reason of breach or negligence by the Escrow Agent, or breach by the Purchaser Representative, under the Escrow Agreement), the Seller shall [***] make each payment to the Purchaser otherwise due to the

35

[***] Certain information in this document has been omitted from this exhibit because it is both (i) not material and (ii) would be competitively harmful if publicly disclosed.

Purchaser hereunder such that the Purchaser receives the full amount of such Novo Sublicense Royalties that would have been payable to the Purchaser had such Baxter Consent Amendment been obtained. Prior to the Seller’s delivery of, or in the event of the failure of the Seller to obtain, an executed copy of the Baxter Consent Amendment, such that delivery by the Seller to the Purchaser Representative of (a) the quarterly royalty reports made pursuant to Section 3.6 of the Novo Sublicense Agreement or (b) material written notices, certificates, offers, proposals, correspondence, reports or other communications delivered pursuant to the Novo Sublicense Agreement relating to the Novo Sublicense Agreement, the Licensed Patents (as defined in the Novo Sublicense Agreement), the Purchased Royalties or any Licensed Product (as defined in the Novo Sublicense Agreement) would constitute a breach by the Seller of its confidentiality obligations under the Novo Sublicense Agreement, the Seller shall deliver to the Purchaser [***], a Material Summary, certified by an officer of the Seller and to the extent providing such summary is not itself a Confidentiality Breach under the Novo Sublicense Agreement, of all information contained in such communication that Seller reasonably believes is material. If Seller is advised in writing by its counsel that providing the Purchaser Representative such Material Summary will constitute a Confidentiality Breach, then the Seller shall provide a Permissible Summary Disclosure to the Purchaser Representative.

(c)    Following the Closing, the Seller shall use commercially reasonable efforts to obtain from Baxter an executed copy of the Baxter Confirmation; provided that the Seller shall not agree to any material changes to the Baxter Confirmation without the prior consent of the Purchaser Representative (not to be unreasonably withheld, conditioned or delayed). If the Seller shall fail to obtain and deliver to the Purchaser Representative an executed copy of the Baxter Confirmation, then solely to the extent the Baxter Royalties are not received by the Purchaser (other than by reason of breach or negligence by the Escrow Agent, or breach by the Purchaser Representative, under the Escrow Agreement), the Seller shall [***] make each payment to the Purchaser otherwise due to the Purchaser hereunder such that the Purchaser receives the full amount of such Baxter Royalties that would have been payable to the Purchaser had the Baxter Confirmation been obtained.

(d)    Following the Closing, the Seller shall use commercially reasonable efforts to obtain from AZ an executed copy of the AZ Confirmation; provided that the Seller shall not agree to any material changes to the AZ Confirmation without the prior consent of the Purchaser Representative (not to be unreasonably withheld, conditioned or delayed). If the Seller shall fail to obtain and deliver to the Purchaser Representative an executed copy of the AZ Confirmation, then solely to the extent the AZ Royalties are not received by the Purchaser (other than by reason of breach or negligence by the Escrow Agent, or breach by the Purchaser Representative, under the Escrow Agreement), the Seller shall [***] make each payment to the Purchaser otherwise due to the Purchaser hereunder such that the Purchaser receives the full amount of such AZ Royalties that would have been payable to the Purchaser had the AZ Confirmation been obtained.

The Seller agrees to indemnify and hold harmless the Purchaser and its Affiliates (including the Purchaser Representative) and any or all of their respective partners, directors, trustees, officers, managers, employees, members, agents and controlling persons (each, a “Purchaser Indemnified Party”) harmless from and against, and will pay to each Purchaser Indemnified Party the amount of, any and all Losses awarded against or incurred or suffered by such Purchaser Indemnified Party, whether or not involving a Third Party Claim, arising out of (a) any breach of any representation or warranty made by the Seller in any of the Transaction Documents or in any certificate delivered by the Seller to the Purchaser or to the Purchaser Representative in writing pursuant to this Purchase and Sale Agreement, (b) any breach of or default under any covenant or agreement of the Seller in any of the Transaction Documents or License Agreements, (c) any Excluded Liabilities and Obligations or (d) any brokerage or finder’s fees or commissions or similar amounts incurred or owed by the Seller 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; provided, however, that the foregoing shall exclude any indemnification to any Purchaser Indemnified Party (i) that has the effect of imposing on the Seller any recourse liability for Purchased Royalties because of the insolvency or other creditworthiness problems of any Counterparty or the insufficiency of the Purchased Royalties, whether as a result of the amount of cash flow arising from sales or licensing of the Products or otherwise, in any case unless resulting from the breach or default by the Seller of or under any of the Transaction Documents or License Agreements, (ii) for any matter in respect of which any Seller Indemnified Party would be entitled to indemnification under Section 8.2, (iii) to the extent resulting from the bad faith, gross negligence or willful misconduct of any Purchaser Indemnified Party, (iv) to the extent resulting from the failure of any Counterparty to perform any of its obligations under any of the License Agreements, unless resulting from the breach or default by the Seller of or under any of the License Agreements or the Transaction Documents or (v) to the extent resulting from acts or omissions of the Seller based upon the written instructions from any Purchaser Indemnified Party. Any amounts due to any Purchaser Indemnified Party hereunder shall be payable by the Seller to such Purchaser Indemnified Party upon demand.

Section 8.2     Indemnification by the Purchaser

The Purchaser and the Purchaser Representative, jointly and severally, agree 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 or the Purchaser Representative in any of the Transaction Documents or any certificate delivered by the Purchaser or the Purchaser Representative 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 or the Purchaser Representative is party or in the Confidentiality Agreement or (c) any brokerage or finder’s fees or commissions or similar

amounts incurred or owed by the Purchaser or the Purchaser Representative 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; provided, however, that the foregoing shall exclude any indemnification to any Seller Indemnified Party (i) to the extent resulting from the bad faith, gross negligence or willful misconduct of any Seller Indemnified Party, (ii) for any matter in respect of which any Purchaser Indemnified Party would be entitled to indemnification under Section 8.1 or (iii) to the extent resulting from acts or omissions of the Purchaser or the Purchaser Representative based upon the written instructions from any Seller Indemnified Party. Any amounts due to any Seller Indemnified Party hereunder shall be payable by the Purchaser and the Purchaser Representative to such Seller Indemnified Party upon demand.

Section 8.3     Procedures 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 8.1 or Section 8.2, 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 8.1 or Section 8.2 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 8.3, 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 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

[***] Certain information in this document has been omitted from this exhibit because it is both (i) not material and (ii) would be competitively harmful if publicly disclosed.

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 obligations or restrictions other than customary and reasonable confidentiality obligations relating to such claim, settlement or compromise.

Section 8.4     Other 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 8.4, the Seller shall be entitled to deliver such notice of demand to the Purchaser Representative on behalf of the Seller Indemnified Parties, and the Purchaser Representative shall be entitled to deliver such notice of demand to the Seller on behalf of the Purchaser Indemnified Parties.

Section 8.5     Time Limitations

(a)    The Seller shall have liability under Section 8.1 with respect to any breach of any representation or warranty made by the Seller in any of the Transaction Documents or certificates delivered by the Seller to the Purchaser or the Purchaser Representative in writing pursuant to this Purchase and Sale Agreement only if the Purchaser Representative notifies the Seller of a claim, specifying the factual basis of such claim in reasonable detail:

(ii)    [***], and

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.

Section 8.7     Limitations

Notwithstanding anything in this Purchase and Sale Agreement to the contrary, (a) in no event shall any Seller Indemnified Party or 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 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 8.3 and (b) the Seller shall not have any liability under Section 8.1 in excess of an amount equal to TWO HUNDRED AND FORTY MILLION DOLLARS ($240,000,000) less the aggregate amount of Purchased Royalties actually received by the Purchaser.

ARTICLE IX

CONFIDENTIALITY

Section 9.1     Confidentiality

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 seventh (7th) 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 (as defined below) 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

41

[***] Certain information in this document has been omitted from this exhibit because it is both (i) not material and (ii) would be competitively harmful if publicly disclosed.

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, 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;

(c)    was independently developed by the Receiving Party, as evidenced by written records, without use of or reference to the Confidential Information or in violation of the terms of this Purchase and Sale Agreement.

Section 9.2     Termination of Confidentiality Agreement

(a)     Effective upon the date hereof, the Existing Confidentiality Agreement shall terminate and be of no further force or effect, and shall be superseded by the provisions of this Article VIII.

Section 9.3     Permitted 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 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

42

[***] Certain information in this document has been omitted from this exhibit because it is both (i) not material and (ii) would be competitively harmful if publicly disclosed.

(including, in the case of the Seller, any party evaluating the acquisition of any portion of the 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 8.5     Other Relevant Obligations. In addition to, and without limiting, Purchaser’s and Purchaser Representative’s obligations under this Article VIII, Purchaser and the Purchaser Representative shall fully comply with any confidentiality obligations of the Seller or any of its Affiliates under the AZ License Agreement, the Baxter License Agreement, the Novo Sublicense Agreement, and the Novo Settlement Agreement that are applicable to the Confidential Information.

ARTICLE XI

MISCELLANEOUS

Section 11.1     Purchaser Representative.

(a)    Each Purchaser hereby appoints and constitutes the Purchaser Representative as agent, proxy and attorney-in-fact, with full power of substitution, to act on behalf of the Purchasers for certain limited purposes, as specified herein, including the full power and authority to act on the Purchasers’ behalf as provided in Section 11.1(b). The Purchasers further agree that such agency, proxy and attorney-in-fact shall be binding upon the successors, heirs, executors, administers and legal representatives of each Purchaser. All decisions, actions, consents and instructions by the Purchaser Representative shall be binding upon all of the Purchasers, and no Purchaser shall have the right to object to, dissent from, protest or otherwise contest any such decision, action, consent or instruction. The Seller shall be entitled to rely on any decision, action, consent or instruction of the Purchaser Representative as being the decision, action, consent or instruction of the Purchasers.

43

[***] Certain information in this document has been omitted from this exhibit because it is both (i) not material and (ii) would be competitively harmful if publicly disclosed.

(b)    The Purchaser Representative shall have such powers and authority as are necessary to carry out the functions assigned to it under this Purchase and Sale Agreement.

(c)    The Purchaser Representative may resign at any time, and may be removed for any reason or no reason by the vote or written consent of the Purchasers. In the event of the resignation or removal of the Purchaser Representative, a new Purchaser Representative shall be appointed by the vote or written consent of the Purchasers. Notice of such vote or a copy of the written consent appointing such new Purchaser Representative shall be sent to the Seller; provided, that until such notice is received, the Seller, as applicable, shall be entitled to rely on the decisions, actions, consents and instructions of the prior Purchaser Representative as described in Section 11.1(a).

Section 11.2     Survival

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.

Section 11.3     Specific Performance

Each Party acknowledges and agrees that, if it fails to perform any of its obligations under any of the Transaction Documents, the other Parties will have no adequate remedy at law.

Section 11.5     Successors and Assigns

45

[***] Certain information in this document has been omitted from this exhibit because it is both (i) not material and (ii) would be competitively harmful if publicly disclosed.

The Seller shall not be entitled to assign any of its rights or delegate any of its obligations under this Purchase and Sale Agreement without the prior written consent of the Purchaser Representative, except that the Seller may, without the consent of the Purchaser Representative, assign its rights and delegate its obligations under this Purchase and Sale Agreement to any other Person into which it may merge, with which it may consolidate or to which it may sell all or substantially all of its assets or all of the business to which any License Agreement relates if such License Agreement, the Intellectual Property Rights related to such License Agreement and the rights and obligations of the Seller hereunder related thereto are transferred together to such other Person; and provided, however, that the assignee under such assignment agrees to be bound by the terms of the Transaction Documents and furnishes a written agreement to the Purchaser Representative, in form and substance reasonably satisfactory to the Purchaser Representative, to that effect. Each Purchaser may, without the consent of the Seller, assign any of its rights and delegate any of its obligations under this Purchase and Sale Agreement without restriction; provided, however, that, notwithstanding anything to the contrary set forth in this Purchase and Sale Agreement, such Purchaser shall not, without the prior written consent of the Seller, assign any of the Purchased Royalties or any of its rights or delegate any of its obligations if any such assignment or delegation would otherwise be inconsistent with or violate any of the provisions contained in any of the License Agreements or the Counterparty Consents that are enforceable. The Purchaser Representative may, without the consent of the Seller, assign its rights and obligations under this Purchase and Sale Agreement in full without restriction; provided, however, that, notwithstanding anything to the contrary set forth in this Purchase and Sale Agreement, (a) the Purchaser Representative shall not, without the prior written consent of the Seller, assign any of its rights or delegate any of its obligations if any such assignment or delegation would otherwise be inconsistent with or violate any of the provisions contained in any of the License Agreements or the Counterparty Consents that are enforceable and the Purchaser Representative, (b) the Purchaser Representative shall not, without the prior written consent of the Seller, assign its rights and obligations in part but not in full and (c) the Purchaser Representative shall not, without the prior written consent of the Seller, assign its rights and obligations to more than one (1) assignee, such that at all times under this Purchase and Sale Agreement, the Purchaser Representative is a single Person. Each Party shall give written notice to the other Parties of any assignment permitted by this Section 11.5 promptly (but in any event within three (3) Business Days) after the occurrence thereof. The Seller shall be under no obligation to reaffirm any representations, warranties or covenants made in this Purchase and Sale Agreement or any of the other Transaction Documents or take any other action in connection with any such assignment by any Purchaser or by the Purchaser Representative. Any purported assignment of rights or delegation of obligations in violation of this Section 11.5 will be void. Subject to the foregoing, this Purchase and Sale Agreement will apply to, be binding upon, and inure to the benefit of, the successors and permitted assigns of the Parties. For the avoidance of doubt, the provisions of Section 6.9 will inure to the benefit of the assigns of the Purchaser.

Section 11.6     Independent Nature of Relationship

The relationship between the Seller and the Purchaser is solely that of seller and purchaser, and neither the Seller nor the Purchaser has any fiduciary or other special relationship with the other Party or any of its Affiliates. This Purchase and Sale Agreement is not a partnership or similar agreement, and nothing contained herein or in any other Transaction Document shall be deemed to constitute the Seller and the Purchaser as a partnership, an association, a joint venture or any other kind of entity or legal form for any purposes, including any Tax purposes. The Parties agree that they shall not take any inconsistent position with respect to such treatment in a filing with any Governmental Authority.

Each Party agrees that a final judgment in any such claim, action, suit or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by Applicable Law.

(c)    The Parties agree that service of process in any claim, action, suit or proceeding referred to in Section 11.8(b) may be served on any Party anywhere in the world, including by sending or delivering a copy of such process to such Party in any manner provided for the giving of notices in Section 11.4.
