Section b.Payments Received In Error; Set-Offs; Interest

29.Commencing on the Closing Date and until the termination of this Agreement, if any payment of any portion of the Royalty is made to the Seller (or to any of the Seller’s Affiliates or designees), then (i) until paid to the Buyer, the Seller shall hold (or cause its Affiliate or designee to hold) such payment received in trust for the benefit of the Buyer, (ii) the Seller (or its Affiliate or designee) shall have no right, title or interest in such payment and shall not pledge or otherwise grant any Lien thereon, and (iii) the Seller shall notify (or shall cause its Affiliate or designee to notify) the Buyer of such wire transfer and provide reasonable details regarding such erroneous Royalty payment and shall pay (or shall cause its Affiliate or designee to pay) an amount equal to such payment to the Buyer, promptly (and in any event within five (5) Business Days) after the receipt thereof, by wire transfer of immediately available funds to an account designated in writing by the Buyer.

30.Commencing on the Closing Date and at all times thereafter, if any payment due under the License Agreement that does not constitute the Royalty is made to the Buyer (or to any of the Buyer’s Affiliates or designees), then (i) until paid to the Seller, the Buyer shall hold (or cause its Affiliate or designee to hold) such payment received in trust for the benefit of the Seller, (ii) the Buyer (or its Affiliate or designee) shall have no right, title or interest in such payment and shall not pledge or otherwise grant any Lien thereon, and (iii) the Buyer shall notify (or shall cause its Affiliate or designee to notify) the Seller of such wire transfer and provide reasonable details regarding such erroneous payment and shall pay (or shall cause its Affiliate or designee to pay) an amount equal to such payment to the Seller, promptly (and in any event within five (5) Business Days) after the receipt thereof, by wire transfer of immediately available funds to an account designated in writing by the Seller.

In connection with the foregoing, the Buyer shall consult with the Seller regarding the taking of any such action and shall consider in good faith the Seller’s comments thereon, it being understood that the Buyer shall have the final decision and right to instruct the Seller to undertake the action at issue.

For purposes of compliance with this Section 5.12(a), the Seller shall (A) employ counsel designated by the Buyer and reasonably acceptable to the Seller; (B) copy the Buyer on all correspondence with such counsel relating to the Dicerna Licensed Patent Rights, the License Agreement, the Products and the Royalty; (C) instruct such counsel to copy the Buyer on all correspondence relating to the Dicerna Licensed Patent Rights, the License Agreement, the Products and the Royalty; (D) instruct such counsel to act as instructed by the Buyer; (E) furnish to the Buyer copies of all communications, proposed filings, and any other documents related to the Prosecution of the Dicerna Licensed Patent Rights in sufficient time to allow for review and comment by the Buyer and implement any such comments; and (F) notify the Buyer of any material developments in such Prosecution as soon as practicable and in any event not less than five (5) Business Days following their occurrence. All costs and expenses incurred in connection with the completion of all Prosecution matters related to the Dicerna Licensed

Patent Rights that have been directed by the Buyer prior to the Closing Date shall be at the sole expense of the Seller, and thereafter at the sole expense of the Buyer. For clarity, the completion of the Prosecution matters contemplated by Section 4.1(k)(ix) and Section 5.12(a)(i) and (ii) shall be at the expense of the Seller. Thereafter, all Prosecution expenses associated with the Dicerna Licensed Patent Rights (including patent renewal fees and patent enforcement expenses) shall be at the expense of the Buyer; provided the Buyer shall have the right to direct the Seller to abandon any Dicerna Licensed Patent Rights if it so chooses (subject to step-in rights in favor of the Seller) and shall have no obligation to enforce any Dicerna Licensed Patent Rights.

42.The Seller shall promptly inform the Buyer of any suspected infringement by a third party of any of the Dicerna Licensed Patent Rights or any other Patent Rights claiming the composition of matter of, formulation of, or the method of making or using, any Product in the Territory. The Seller shall provide to the Buyer a copy of any written notice of any suspected infringement in the Territory of any of the Dicerna Licensed Patent Rights and all pleadings filed in such action. The Seller shall, if requested in writing by the Buyer, promptly, and in any event within five (5) Business Days after receipt of such request, bring an action to enforce the Dicerna Licensed Patent Rights as instructed by the Buyer. The Seller shall not bring any enforcement action related to the Dicerna Licensed Patent Rights without the Buyer’s prior consent. The Seller shall act only as instructed by the Buyer to enforce and defend the Dicerna Licensed Patent Rights, including by bringing any legal action for infringement or defending any counterclaim of invalidity or unenforceability or action of a third party for declaratory judgment of non-infringement or non-interference. For purposes of compliance with this Section 5.12(b), the Seller shall (i) employ counsel designated by the Buyer; (ii) copy the Buyer on all correspondence with such counsel relating to the Dicerna Licensed Patent Rights, the License Agreement, the Products and the Royalty; (iii) instruct such counsel to copy the Buyer on all correspondence relating to the Dicerna Licensed Patent Rights, the License Agreement, the Products and the Royalty; (iv) instruct such counsel to act as instructed by the Buyer; (v) furnish to the Buyer copies of all communications, proposed filings, and any other documents related to any defense or enforcement action involving the Dicerna Licensed Patent Rights in sufficient time to allow for review and comment by the Buyer and implement such comments; and (vi) notify the Buyer of any material developments in such defense or enforcement as soon as practicable and in any event not less than five (5) Business Days following their occurrence. All costs and expenses incurred in connection with any enforcement or defense action involving the Dicerna Licensed Patent Rights taken at the direction of the Buyer shall be at the sole expense of the Buyer.

43.Except as set forth herein, each of the Buyer and the Seller shall bear its own fees and expenses incurred in Prosecuting, defending and enforcing the Dicerna Licensed Patent Rights. The Proceeds resulting from any defense or enforcement of the Dicerna Licensed Patent Rights shall be applied first to reimburse the Seller and the Buyer for any expenses incurred by them in connection with such defense or enforcement, with the remainder of the Proceeds distributed to (i) the Buyer to the extent such defense or enforcement is related to the Products and (ii) the Seller to the extent such defense or enforcement is not related to the

Products. The Seller hereby assigns and, if not presently assignable, agrees to assign to the Buyer the amount of Proceeds due to the Buyer in accordance with this Section 5.12(c).

Section m.Efforts to Consummate Transactions

. Subject to the terms and conditions of this Agreement, each of the Seller and the Buyer shall use its commercially reasonable efforts to take, or cause to be taken, all actions and to do, or cause to be done, all things reasonably necessary under applicable law to consummate the transactions contemplated by this Agreement. Each of the Buyer and the Seller agrees to execute and deliver such other documents, certificates, agreements and other writings and to take such other actions as may be reasonably necessary in order to consummate or implement expeditiously the transactions contemplated by this Agreement.

Section n.Licensee Instruction Letter

. Promptly after the Closing, the Seller shall use commercially reasonable efforts to obtain Licensee’s duly executed acknowledgement of the Licensee Instruction Letter as promptly as practicable. If Licensee refuses or otherwise fails to execute such Licensee Instruction Letter, or if the Buyer so requests, (i) the Seller shall promptly deliver to the Buyer and Licensee a payment instruction letter, in substantially the form attached hereto as Exhibit F, duly executed by the Seller, instructing Licensee to pay the Royalty directly to the Buyer, and (ii) the Seller shall thereafter use commercially reasonable efforts to obtain Licensee’s agreement to provide to the Buyer, simultaneously with delivery of the same to the Seller, copies of all Royalty Reports that are provided to the Seller under the License Agreement. For the avoidance of doubt and notwithstanding anything herein to the contrary, Licensee’s refusal to (i) sign the Licensee Instruction Letter, (ii) adhere to any payment instructions delivered pursuant to this Agreement, or (iii) agree to deliver copies of all Royalty Reports that are provided to the Seller under the License Agreement shall not be considered a breach of this Agreement by the Seller.

Section o.Tax Matters

. Notwithstanding anything to the contrary in this Agreement, the Seller and the Buyer shall treat the transactions contemplated by this Agreement as a sale of the Royalty for United States federal, state, local and non-U.S. Tax purposes. Accordingly, any and all Royalty payments made pursuant to the License Agreement after the Closing Date shall be treated as made to the Buyer for United States federal, state, local and non-U.S. Tax purposes. The parties shall cooperate to effect the foregoing treatment for United States federal, state, local and non-U.S. Tax purposes in the event that, notwithstanding the Licensee Instruction Letter, a Licensee, any sublicensee or any other Person makes any future remittance of Royalty payments to the Seller which the Seller must remit to the Buyer pursuant to Section 5.2(a). Notwithstanding anything to the contrary in this Agreement, the Seller shall have no obligation to gross-up or otherwise pay the Buyer any amounts with respect to any withholding or deduction for or on account of any Taxes. The parties hereto agree not to take any position that is inconsistent with the provisions of this Section 5.15 on any Tax return or in any audit or other administrative or judicial proceeding unless (i) the other party hereto has consented to such actions or (ii) the party hereto that contemplates taking such an inconsistent position has been advised by nationally

recognized tax counsel in writing that there is no “reasonable basis” (within the meaning of Treasury Regulation Section 1.6662-3(b)(3)) for the position specified in this Section 5.15. If there is an inquiry by any Governmental Entity of the Seller or the Buyer related to this Section 5.15, the parties hereto shall cooperate with each other in responding to such inquiry in a reasonable manner consistent with this Section 5.15.

Section p.Further Assurances

. After the Closing, the Seller and the Buyer agree to execute and deliver such other documents, certificates, agreements and other writings and to take such other actions as may be reasonably necessary in order to give effect to the transactions contemplated by this Agreement.

Article 7.
INDEMNIFICATION

Section a.General Indemnity

. Subject to Section 7.3, from and after the Closing:

51.the Seller hereby agrees to indemnify, defend and hold harmless the Buyer and its Affiliates and its and their directors, managers, trustees, officers, agents and employees (the “Buyer Indemnified Parties”) from, against and in respect of all Losses suffered or incurred by the Buyer Indemnified Parties to the extent arising out of or resulting from (i) any breach of any of the representations or warranties (in each case, when made) of the Seller in this Agreement or the ▇▇▇▇ of Sale and (ii) any breach of any of the covenants or agreements of the Seller in this Agreement or the ▇▇▇▇ of Sale; provided, however, that the foregoing shall exclude any indemnification to any Buyer Indemnified Party to the extent resulting from (i) the gross negligence, willful misconduct, or fraud of any Buyer Indemnified Party, or (ii) acts or omissions of the Seller or any of its Affiliates solely based upon, and in conformity with, the Buyer’s express written instructions (unless the Seller is otherwise liable for such Losses pursuant to the terms of this Agreement or the ▇▇▇▇ of Sale); and

52.the Buyer hereby agrees to indemnify, defend and hold harmless the Seller and its Affiliates and its and their directors, officers, agents and employees (the “Seller Indemnified Parties”) from, against and in respect of all Losses suffered or incurred by the Seller Indemnified Parties to the extent arising out of or resulting from (i) any breach of any of the representations or warranties (in each case, when made) of the Buyer in this Agreement or the ▇▇▇▇ of Sale, (ii) any breach of any of the covenants or agreements of the Buyer in this Agreement or the ▇▇▇▇ of Sale, or (iii) any action or inaction taken by the Seller solely based upon, and in conformity with, the Buyer’s express written instruction or direction pursuant to Section 5.10, Section 5.12(a) or Section 5.12(b), solely to the extent such Losses are due to a claim brought by a third party arising from an action or inaction taken by the Seller pursuant to Section 5.10, Section 5.12(a) or Section 5.12(b) at the Buyer’s request; provided, however, that the foregoing shall exclude any indemnification to any Seller Indemnified Party to the extent resulting from the gross negligence, willful misconduct, or fraud of any Seller Indemnified Party.

Section b.Notice of Claims

. If either a Buyer Indemnified Party, on the one hand, or a Seller Indemnified Party, on the other hand (such Buyer Indemnified Party on the one hand and such Seller Indemnified Party on the other hand being hereinafter referred to as an “Indemnified Party”), has suffered or incurred any Losses for which indemnification may be sought under this Article 7, the Indemnified Party shall so notify the other party from whom indemnification is sought under this Article 7 (the “Indemnifying Party”) promptly in writing describing such Loss, the amount or estimated amount thereof, if known or reasonably capable of estimation, and the method of computation of such Loss, all with reasonable particularity and containing a reference to the provisions of this Agreement in respect of which such Loss shall have occurred. If any claim,

action, suit or proceeding is asserted or instituted by or against a third party with respect to which an Indemnified Party intends to claim any Loss under this Section 7.2, such Indemnified Party shall promptly notify the Indemnifying Party of such claim, action, suit or proceeding and tender to the Indemnifying Party the defense of such claim, action, suit or proceeding. A failure by an Indemnified Party to give notice and to tender the defense of such claim, action, suit or proceeding in a timely manner pursuant to this Section 7.2 shall not limit the obligation of the Indemnifying Party under this Article 7, except to the extent such Indemnifying Party is actually prejudiced thereby.

Section c.Limitations on Liability

. No party hereto shall be liable for any consequential, punitive, special or incidental damages under this Article 7 (and no claim for indemnification hereunder shall be asserted) as a result of any breach or violation of any covenant or agreement of such party (including under this Article 7) in or pursuant to this Agreement. Notwithstanding the foregoing, the Buyer shall be entitled to make indemnification claims, in accordance with the procedures set forth in this Article 7, for Losses that include any portion of the Royalty that the Buyer was entitled to receive but did not receive timely or at all due to any indemnifiable events under this Agreement, and such portion of the Royalty shall not be deemed consequential, punitive, special or incidental damages for any purpose of this Agreement.

Section d.Third Party Claims

. Upon providing notice to an Indemnifying Party by an Indemnified Party pursuant to Section 7.2 of the commencement of any action, suit or proceeding against such Indemnified Party by a third party with respect to which such Indemnified Party intends to claim any Loss under this Article 7, such Indemnifying Party shall have the right to defend such claim, at such Indemnifying Party’s expense and with counsel of its choice reasonably satisfactory to the Indemnified Party. If the Indemnifying Party assumes the defense of such claim, the Indemnified Party shall, at the request of the Indemnifying Party, use commercially reasonable efforts to cooperate in such defense; provided, that the Indemnifying Party shall bear the Indemnified Party’s reasonable out-of-pocket costs and expenses incurred in connection with such cooperation. So long as the Indemnifying Party is conducting the defense of such claim as provided in this Section 7.4, the Indemnified Party may retain separate co-counsel at its expense and may participate in the defense of such claim, and the Indemnifying Party shall not consent to the entry of any Judgment or enter into any settlement with respect to such claim without the prior written consent of the Indemnified Party unless such Judgment or settlement (A) provides for the payment by the Indemnifying Party of money as sole relief (if any) for the claimant (other than customary and reasonable confidentiality obligations relating to such claim, Judgment or settlement), (B) results in the full and general release of the Indemnified Party from all liabilities arising out of, relating to or in connection with such claim and (C) does not involve a finding or admission of any violation of any law, rule, regulation or Judgment, or the rights of any Person, and has no effect on any other claims that may be made against the Indemnified Party. In the event the Indemnifying Party does not or ceases to conduct the defense of such claim as so provided, (i) the Indemnified Party may defend against, and consent to the entry of any

reasonable Judgment or enter into any reasonable settlement with respect to, such claim in any manner it may reasonably deem to be appropriate, (ii) subject to the limitations set forth in Section 7.3, the Indemnifying Party shall reimburse the Indemnified Party promptly and periodically for the reasonable out-of-pocket costs of defending against such claim, including reasonable attorneys’ fees and expenses against reasonably detailed invoices, and (iii) the Indemnifying Party shall remain responsible for any Losses the Indemnified Party may suffer as a result of such claim to the full extent provided in this Article 7.

Section e.Exclusive Remedy

. Except as set forth in Section 9.11, from and after Closing, the rights of the parties hereto pursuant to (and subject to the conditions of) this Article 7 shall be the sole and exclusive remedy of the parties hereto and their respective Affiliates with respect to any claims (whether based in contract, tort or otherwise) resulting from or relating to any breach of the representations, warranties covenants and agreements made under this Agreement or any certificate, document or instrument delivered hereunder, and each party hereto hereby waives, to the fullest extent permitted under applicable law, and agrees not to assert after Closing, any other claim or action in respect of any such breach. Notwithstanding the foregoing, claims for fraud shall not be waived or limited in any way by this Article 7.

Article 8.
TERMINATION

Section a.Automatic Termination

. This Agreement shall continue in full force and effect until sixty (60) days after such time as Licensee is no longer obligated to make any payments of the Royalty, at which point this Agreement shall automatically terminate, except with respect to any rights and obligations that shall have accrued prior to such termination and remain unpaid or unsatisfied or that specifically survive termination hereunder.

Section b.Survival

Notwithstanding anything to the contrary in this Article 8, the following provisions shall survive termination of this Agreement: Section 5.1 (Disclosures), Section 5.2 (Payments Received in Error; Set-Offs; Interest), Section 5.5 (Inspections and Audits of Licensee) (for the time period such rights may be exercised under Section 6.4.1 of the License Agreement), Article 7 (Indemnification), Section 8.2 (Survival), and Article 9 (Miscellaneous).

Each party further agrees that, in the event of any action for specific performance in respect of such breach or violation, it shall not assert that the defense that a remedy at law would be adequate.
