Section 5.2 Payments.

(a) Payments.

(i) Promptly, and in any event, within [**] following the Closing, the Seller shall deliver to the Licensee (x) an instruction letter, in substantially the form attached hereto as Exhibit G (the “Licensee Instruction Letter”), duly executed by the Buyer and the Seller, requesting that the Licensee pay the Assigned Royalty Payments to an account designated by the Buyer and deliver Royalty Reports directly to the Buyer simultaneously with delivery of Royalty Reports to the Seller, and (y) an IRS Form W-8BEN-E provided by Buyer pursuant to Section 3.5 hereof. If, prior to the first Commercial Sale of Product, the Licensee does not agree to make payment of the Assigned Royalty Payments to an account designated by the Buyer, then (x) the parties shall execute and deliver to the Escrow Agent within [**] after the First Commercial Sale of a Product the Escrow Agreement and (y) the Seller shall instruct the Licensee to make all payments of the Royalty to the

Escrow Account until such time as the Assigned Royalty Cap is met. In the event that the Seller sells, transfers, assigns or otherwise conveys any portion of its retained rights in the Royalty to an Affiliate or Third Party, the Buyer agrees not to object to amending, and to reasonably cooperate to amend, the Escrow Agreement to add any such Affiliate or Third Party for the purposes of directing to such Third Party any portion of the Royalty to which such Third Party may be entitled as a result of such transaction. In no event shall the Escrow Agreement permit the Escrow Agent to distribute payments of the Royalty to the parties other than in accordance with each party’s applicable Pro Rata Portion, or to withhold any distribution to the parties (whether as a result of any claims between the parties or otherwise), in each case without the prior written consent of both parties.

(ii) If, notwithstanding the terms of this Agreement, the Licensee Instruction Letter and the Escrow Agreement, as applicable, the Licensee, or any other Person, makes any payment in respect of the Assigned Royalty Payments to the Seller (or to any of the Seller’s Affiliates or designees) instead of to the Buyer or the Escrow Account, as applicable, then: (A) the Seller shall hold (or shall cause such Affiliate or designee to hold) such payment in trust for the sole benefit of the Buyer, (B) the Seller (or such Affiliate or designee) shall have no right, title or interest whatsoever in such payment and shall not create or suffer to exist any Lien thereon, and (C) the Seller (or such Affiliate or designee) promptly, and in any event no later than [**] following the receipt by the Seller (or such Affiliate or designee) of such payment, shall remit, or cause to be remitted, an amount equal to such payment to an account designated in writing by the Buyer or to the Escrow Account to be distributed pursuant to the Escrow Agreement, as applicable.

(iii) If, notwithstanding the terms of this Agreement, the Licensee Instruction Letter and the Escrow Agreement, as applicable, the Licensee, or any other Person, makes any payment due under the License Agreement that does not constitute an Assigned Royalty Payment, to the Buyer (or to any of the Buyer’s Affiliates or designees) instead of to the Seller or the Escrow Account, as applicable, or as otherwise instructed by the Seller, then: (A) the Buyer shall hold (or shall cause such Affiliate or designee to hold) such payment in trust for the sole benefit of the Seller, (B) the Buyer (or such Affiliate or designee) shall have no right, title or interest whatsoever in such payment and shall not create or suffer to exist any Lien thereon, and (C) the Buyer (or such Affiliate or designee) promptly, and in any event no later than [**] following the receipt by the Buyer (or such Affiliate or designee) of such payment, shall remit, or cause to be remitted, an amount equal to such payment to an account designated in writing by the Seller or to the Escrow Account to be distributed pursuant to the Escrow Agreement, as applicable.

(b) If either the Seller or the Buyer fails to timely comply with their respective obligations under Section 5.2(a), then all amounts not timely paid by the due date provided therein shall accrue interest from and including the date such amount was due through but excluding the date such payment in full (together with all interest thereon) is made to the applicable party, at a rate, calculated on a 365-day or 366-day basis, as applicable, equal to the then-current Prime Rate plus [**] percent ([**]%), compounded annually, not to exceed the maximum interest that may be charged under applicable law.

(c) Except as set forth in Section 5.2(a)(i), the Seller shall not revoke, amend, modify, supplement, restate, waive, cancel or terminate the Licensee Instruction Letter or any instruction to the Licensee to make payments in respect of the Royalty to the Escrow Agent without the prior written consent of Buyer.

Section 5.3 Royalty Reductions. If Licensee exercises any Royalty Reduction against any payment of the Royalty that is not (a) a Permitted Royalty Reduction, (b) the result of any Credit Event or (c) a breach by Licensee of its payment obligations under the License Agreement, such Royalty Reduction shall not reduce the amount of any Assigned Royalty Payments to which the Buyer is entitled, and if such Royalty Reduction reduces any payment of the Assigned Royalty Payments to less than the full amount of the Assigned Royalty Payments, then the Seller shall promptly (and in any event within [**] following the payment of the Assigned Royalty Payments affected by such Royalty Reduction) make a true-up payment to the Buyer such that the Buyer receives the full amount of such Assigned Royalty Payments that would have been payable to the Buyer had such Royalty Reduction not occurred. The Seller agrees to notify the Buyer in writing as promptly as possible (and in any event within [**]) of becoming aware of any actual or potential Royalty Reductions, including Permitted Royalty Reductions. For the avoidance of doubt, any nonpayment by Licensee as a result of a Credit Event or a breach by Licensee of its payment obligations under the License Agreement shall not constitute a Royalty Reduction for purposes of this Section 5.3 and shall not obligate the Seller to make any payment under this Section 5.3 (unless and until such nonpayment is cured). For all purposes hereunder, any true-up payment made pursuant to this Section 5.3 will be treated as paid with respect to the Royalty for U.S. federal income tax purposes to the fullest extent permitted by applicable law.

From and after such time as the Licensee has agreed to provide copies of Royalty Reports directly to the Buyer pursuant to the Instruction Letter, the Seller shall as promptly as possible (and in any event within [**]) deliver to the Buyer copies of any Royalty Reports not provided to the Buyer directly, and any supporting

documentation, information, or other reports (if any) received by the Seller from Licensee relating to the Royalty for such Calendar Quarter to the extent not provided to the Buyer directly.

(b) The Seller agrees to request that Roche deliver Product Information (other than a Royalty Report as provided in Section 5.4(a) above) to the Buyer directly as more fully described in, and in accordance with the terms of, Exhibit I. Until such time as the Licensee has agreed to deliver Product Information (other than Royalty Reports) directly to the Buyer, the Seller agrees to deliver to the Buyer, at least on a [**] basis, new or updated Product Information that the Seller receives from the Licensee. On an at least [**] basis, the Seller shall deliver to the Buyer a reasonably detailed summary of new or updated information of which it has Knowledge about any decision, order, dispute or challenge, of or related to the validity, patentability, scope, priority, construction, non-infringement, inventorship, ownership or enforceability of any of the PTC Patent Rights, the Joint Patent Rights Patent or Roche Patent Rights or any claim thereof, or opposition of the grant of any patent that falls within the PTC Patent Rights, Joint Patent Rights or Roche Patent Rights, in any legal or administrative proceedings, including in a court of law, before the United States Patent and Trademark Office or other agency or tribunal in any jurisdiction, or in arbitration, including by reexamination, inter partes review, opposition, interference, post-grant review, nullity proceeding, preissuance submission, third party submission, derivation proceeding or declaratory judgment action.

(c) The Seller agrees to notify the Buyer within [**] after the Seller’s receipt or Knowledge of a Third Party Paragraph IV certification with respect to the PTC Patent Rights, the Joint Patent Rights or the Roche Patent Rights. The Seller shall provide the Buyer [**] with a list, substantially in the form of Schedule 4.1(j)(i) of the Disclosure Schedule, of PTC Patent Rights and Joint Patent Rights Handled by the Seller or of which the Seller then has Knowledge covering the Product.

(d) Notwithstanding the foregoing, until such time as the Licensee has agreed to deliver Product Information directly to the Buyer, if the Seller is advised by its counsel that providing the Buyer with a true, correct and complete copy of Product Information or other documents or information pursuant to this Agreement (whether pursuant to this Section 5.4 or otherwise) would be reasonably expected to constitute a material breach by the Seller of its confidentiality obligations under the License Agreement (a “Confidentiality Breach”), then the Seller shall, in lieu of delivery of such Product Information, provide a written summary thereof to the Buyer describing in as much detail as would not result in a Confidentiality Breach, the substance of such Product Information or other documents or information.

Section 5.5 Actions under the License Agreement while the Seller is the Control Party. The following provisions shall only apply while the Seller is the Control Party:

Notwithstanding the foregoing, no prior consent of the Buyer shall be required for the Seller to deliver notice pursuant to Sections 7.15 or 20.2 of the License Agreement, provided, that the Seller shall deliver to the Buyer any notices it delivers to Licensee pursuant to Section 7.15 of the License Agreement substantially concurrently with delivery of such notice to Licensee.

Promptly (and in any event within [**]) after the Seller becomes aware of, or comes to believe in good faith that there has been, a breach of the License Agreement or the Sponsored Research Agreement by Licensee or the Foundation, the Seller shall provide notice of such breach to the Buyer. In addition, the Seller shall provide to the Buyer a copy of any written notice of such breach or alleged breach of the License Agreement or the Sponsored Research Agreement delivered by the Seller to Licensee as soon as practicable and in any event not less than [**] following such delivery.

(ii) Enforcement of License Agreement. In the case of any breach by Licensee or the Foundation referred to in Section 5.6(d)(i), the Seller shall consult with the Buyer regarding the timing, manner and conduct of any enforcement of Licensee’s obligations under the License Agreement or the Foundation’s obligations under the Sponsored Research Agreement. Following such consultation, the Seller shall, (i) as reasonably instructed by the Buyer, exercise such rights and remedies relating to any such breach as shall be available to the Seller, whether under the License Agreement, the Sponsored Research Agreement or by operation of law and, (ii) if such breach is related to the Royalty or would reasonably be expected (with or without the giving of notice or passage of time, or both) to result in a Product MAE, employ such counsel reasonably acceptable to the Seller as the Buyer shall select for such purpose.

(iii) Allocation of Proceeds and Costs of Enforcement. Each of the Buyer and the Seller shall bear its own fees and expenses incurred in enforcing Licensee’s obligations under the License Agreement pursuant to this Section

5.6(d), provided that the Buyer shall pay its Pro Rata Portion of the reasonable and documented costs and expenses incurred by the Seller in connection with the Seller’s enforcement of the License Agreement in accordance with Section 5.6(d)(ii) (net of any amounts reimbursable by Licensee). The Proceeds resulting from any enforcement of Licensee’s obligations under the License Agreement shall be applied first to reimburse the Seller and the Buyer for any expenses incurred by them in connection with such enforcement, and the remainder of the Proceeds shall be allocated between the Seller and the Buyer as though such Proceeds constituted Royalty payments. 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 5.6(d).

Section 5.7 Inspections and Audits of Licensee. If either party desires to cause an inspection as provided under Section 14 of the License Agreement, then the Seller and the Buyer agree to consult in good faith with each other in connection therewith. Following such consultation, the Seller may, or if requested by the Buyer, shall, promptly provide written notice to Licensee to cause such an inspection. The Seller shall, for purposes of Section 14 of the License Agreement, select such independent certified public accounting firm as is reasonably acceptable to both the Seller and the Buyer (as long as such independent certified public accountant is reasonably acceptable to Licensee as required by Section 14 of the License Agreement). Each of the Buyer and the Seller shall be responsible for its Pro Rata Portion of the expense of any inspection or audit undertaken by either the Buyer or the Seller (including the fees and expenses of such independent certified public accounting firm designated for such purpose) that would otherwise be borne by the Seller pursuant to the License Agreement (if and as such expenses are actually incurred by the Seller). The Seller shall deliver to the Buyer a copy of the results of any audit conducted pursuant to Section 14 of the License Agreement within [**] following the Seller’s receipt thereof (and the results of any such audit shall be considered Product Information). If an audit reveals an underpayment by the Licensee, then the Royalty shall include the amount paid by the Licensee to the Seller to compensate for such underpayment in accordance with Section 14.2 of the License Agreement, with interest thereon as set forth in Section 12.2 of the License Agreement. If an audit reveals an overpayment by the Licensee, then the Seller shall comply with its obligations set forth in Section 14.2 of the License Agreement and, in furtherance thereof, may, in its sole discretion, require that the Buyer pay the Seller an amount equal to the Buyer’s Pro Rata Portion of such overpayment or credit an amount equal to the Buyer’s Pro Rata Portion of such overpayment against future Assigned Royalty Payments.

Section 5.8 Termination of License Agreement.

(a) The Seller shall not, without the prior written consent of the Buyer, (i) exercise any right to terminate the License Agreement, in whole or in part, (ii) agree with Licensee to terminate the License Agreement, in whole or in part, or (iii) take, or permit any Affiliate or sublicensee to take, any action that would reasonably be expected to give Licensee the right to terminate the License Agreement, in whole or in part. The Seller shall not take any action, fail to take an action or permit an action to be taken, that would give Licensee the right to terminate the License Agreement under Section 20.3.1 thereof, provided that in no event shall the

Seller be obligated to prevent any termination of the License Agreement as a result of a Credit Event so long as such termination is not also a result of any affirmative action of the Seller.

(b) Effect of Termination.

(i) In the event that the License Agreement is terminated while the Seller is the Control Party and prior to a Change of Control of the Seller, and the Seller has rights under Section 20.4 of the License Agreement, the Seller shall have the right in its sole discretion to determine whether and how to continue the development and commercialization of Compounds and Products as provided in Section 20.4 of the License Agreement (including via direct sales by the Seller or its Affiliates and licenses to one or more distributors and other Third Parties on a regional basis); provided, that, the Seller shall consult with the Buyer as to its plans (a “Seller Direct Undertaking”). If the Seller, in its sole discretion, determines to completely out-license to one or more Third Parties (each, a “Seller New Licensee”) the global development and commercialization of Compounds and Products (a “Seller New Arrangement”), the Seller shall notify the Buyer in writing and shall promptly provide copies of any license agreement with a Seller New Licensee for the continued commercialization of the Compounds and Products, and commercialization plans therefor.

(ii) If the License Agreement is terminated in whole or in part by Licensee pursuant to Section 20.3.3 (Termination Without a Cause) or by the Seller pursuant to Section 20.3.1 (Termination for Breach), Section 20.3.4 (Termination for Patent Challenge) or Section 20.3.5 (Termination for Post-Change of Control Material Change) in each case of the License Agreement while the Buyer is the Control Party or following a Change of Control of the Seller (any such termination while the Buyer is the Control Party or following a Change of Control of the Seller, a “Triggering Termination”), then the Seller shall have the first right to continue development and commercialization of Compounds and Products as provided in Section 20.4.1 of the License Agreement and pursue its rights under Sections 20.4.1.1, 20.4.1.2, 20.4.1.3, 20.4.1.4(i), 20.4.1.4(ii), 20.4.1.4(iii), 20.4.1.4(iv), 20.4.1.4(v), 20.4.1.5, 20.4.1.6, 20.4.1.7, 20.4.1.8 and 20.4.3 of the License Agreement (collectively, the “Reversionary Rights”). The Seller shall inform the Buyer in writing within [**] of a Triggering Termination whether or not it has elected to pursue the Reversionary Rights and shall thereafter keep Buyer reasonably informed as to the status of, and shall use commercially reasonable efforts in connection with, the pursuit of such development and commercialization under the Reversionary Rights, including delivering to the Buyer concurrently with deliver of the same to Licensee, notice pursuant to Section 20.4.1.9 of the License Agreement. In the event that the Seller does not notify the Buyer in writing that the Seller has elected to pursue the Reversionary Rights within [**] of a Triggering Termination, the Buyer shall have the right to cause the Seller to pursue the Reversionary Rights by delivering written notice to the Seller and the Seller shall act as reasonably instructed by the

Buyer to pursue the Reversionary Rights. The Buyer shall indemnify, defend and hold harmless the Seller and its Affiliates against and in respect of all Losses suffered or incurred by the Seller or its Affiliates to the extent arising out of or resulting from the Seller’s or its Affiliates’ exercise of the Reversionary Rights solely at the Buyer’s direction following a Triggering Termination, other than (A) the Seller’s Pro Rata Portion of any out of pocket fees, including attorneys’, consultants’ or other professional advisor costs and expenses incurred in connection with exercising its Reversionary Rights pursuant to this Section 5.8(b)(ii) or as contemplated by Section 5.8(b)(iii) and (B) costs, expenses or other amounts attributable to the development, manufacture and commercialization of Compounds and Products under the License Agreement or the Sponsored Research Agreement that would otherwise have been borne by the Seller and its Affiliates. The Seller shall promptly, and in any event within [**], provide the Buyer with access to all materials, reports, information and property delivered, provided or otherwise made available to the Seller in connection with such Triggering Termination, the Licensee’s ongoing obligations and the Reversionary Rights.

(iii) If there is a Triggering Termination and the Buyer is pursuing the Reversionary Rights pursuant to Section 5.8(b)(ii), the Buyer shall have the exclusive right to negotiate one or more licenses or sublicenses to continue to commercialize any Product that has obtained Regulatory Approval (each, a “Marketed Product”) with one or more Third Parties under the Reversionary Rights (each such license or sublicense, a “Buyer Negotiated Arrangement”). The Seller shall reasonably cooperate with the Buyer, at the Buyer’s direction, in connection with the negotiation, execution and delivery of any Buyer Negotiated Arrangement. Except with respect to the license or sublicense of any intellectual property rights included in the Reversionary Rights (which licenses or sublicenses shall be limited to the commercialization of the Marketed Product and any related development activities specifically with respect to such Marketed Product), no Buyer Negotiated Arrangement shall include terms, conditions and limitations that are, in the aggregate, more burdensome to the Seller than the licensing or sublicensing terms contained in the License Agreement. The Buyer shall reimburse the Seller for the Buyer’s Pro Rata Portion of any out of pocket fees, including attorneys’, consultants’ or other profession advisor costs and expenses incurred in connection with the pursuit, negotiation or execution of any Buyer Negotiated Arrangement.

(iv) In connection with any Seller Direct Undertaking, Seller New Arrangement or Buyer Negotiated Arrangement, (a) the Buyer shall be provided with economic rights equivalent to those remaining under this Agreement and with substantially the same other rights as provided in this Agreement, and (b) the Seller’s rights and obligations under this Agreement in respect of the License Agreement shall otherwise apply to any Seller Direct Undertaking, any Seller New Arrangement or any Buyer Negotiated Arrangement, in each case mutatis

mutandis. In connection with any Buyer Negotiated Arrangement, the Seller shall be provided with economic rights equivalent to those remaining under this Agreement and with substantially the same other rights as provided in this Agreement. As soon as practicable following the Seller delivering written notice to the Buyer of any Seller Direct Undertaking or the execution of any Seller New Arrangement or Buyer Negotiated Arrangement by each party thereto, the Buyer and the Seller shall cooperate with one another to enter into new agreements (or to make amendments or modifications to this Agreement, the Bill of Sale and such other documents and the Buyer may reasonably request) to effect this clause (iv).

Section 5.9 No Liens. The Seller shall not hereafter mortgage, pledge, hypothecate or grant a security interest or other Lien of any kind in (i) the Assigned Royalty Payments (other than a Permitted Lien) or (ii) any of its interest in any portion of the PTC Patent Rights, Joint Patent Rights, any Product or the License Agreement (other than a Permitted Lien).

Section 5.10 Enforcement; Defense; Prosecution and Maintenance.

(a) The Seller shall promptly inform the Buyer of any suspected infringement by a Third Party of any of the Licensed IP or if any Third Party alleges that manufacture, use, sale, offer for sale or import of a Product infringes the intellectual property rights of a Third Party. The Seller shall (i) provide to the Buyer a copy of any written notice of any such suspected infringement and all pleadings filed in such action and (ii) notify the Buyer of any material developments in any claim, suit or proceeding resulting from such infringement that are delivered by or to Licensee or the Seller under Sections 15.8 and 15.9 of the License Agreement or otherwise as soon as practicable and in any event not less than [**] following such delivery.

(b) In the event the Buyer is the Control Party, and if the Seller has the right to join or assume the defense or pursuit of an enforcement action pursuant to Section 15.8 or 15.9 of the License Agreement, the Seller shall, if requested in writing by the Buyer, promptly, and in any event within [**] after receipt of such request, exercise such right as reasonably instructed by the Buyer and, if requested by the Buyer, the Seller shall employ such counsel reasonably acceptable to the Seller as the Buyer shall select for such purpose, provided that the Buyer shall pay its Pro Rata Portion of the costs and expenses of any such counsel. In the event the Buyer is the Control Party, the Seller shall not, except as reasonably instructed by the Buyer, exercise any consent or consultation rights under Section 15.8 or 15.9 of the License Agreement. In the event the Buyer is the Control Party, the Seller shall not, except as reasonably instructed by the Buyer, join any infringement action under Section 15.8 or 15.9 of the License Agreement. To the extent the Seller exercises its right to join or assume the defense or pursue an action while the Buyer is the Control Party pursuant to this Section 5.10(b), the Seller shall act as reasonably instructed by the Buyer satisfy its obligations under Section 15.8 or 15.9 of the License Agreement, including to (1) diligently defend or enforce any Licensed Patents (including by bringing and defending any counterclaim of invalidity or unenforceability, defending against any action of a Third Party for declaratory judgment of non-infringement or non-interference or bringing any legal action for infringement) and (2) not disclaim or abandon, or fail to take any

action necessary or desirable to prevent the disclaimer, abandonment or dismissal (including through lack of enforcement against Third Party infringers) of any defense of invalidity or unenforceability or any legal action for infringement of any Licensed Patents in the Territory for which it has elected to join or assume the defense or pursue an enforcement action pursuant to this Section 5.10(b).

(c) Promptly (and in any event within [**]) following the Seller’s receipt of written notice from the Licensee pursuant to Section 15.4 or 15.5 of the License Agreement of the Licensee’s intention to allow any of the Roche Patent Rights or the Joint Patent Rights in the Territory to lapse or become abandoned or to not file patent applications for any of the Roche Patent Rights or Joint Patent Rights in the Territory (such Patent Rights, the “Applicable Listed Patents”), the Seller shall inform the Buyer of such notice and, if the Buyer is the Control Party, the Seller shall, as mutually agreed with the Buyer, exercise its rights under Section 15.4 or 15.5 of the License Agreement to assume the prosecution and maintenance of any such Applicable Listed Patents and each of the Buyer and the Seller shall pay its Pro Rata Portion of the expenses in connection therewith. If the Seller, in its reasonable discretion and after consultation with the Buyer, determines to abandon or not file any patent applications, the Buyer shall have the right, at its sole expense, to direct the Seller to assume the prosecution and maintenance of any such Applicable Listed Patents and the Buyer shall be solely responsible for the expenses in connection therewith.

(d) The Seller shall satisfy, at its own expense, its prosecution obligations under Sections 15.3, 15.4 and 15.5 of the License Agreement, which actions while the Buyer is the Control Party shall be reasonably determined by the Buyer after consultation with the Seller, including to (i) take any and all actions, and prepare, execute, deliver and file any and all agreements, documents and instruments, that are reasonably necessary or desirable to diligently prosecute, preserve and maintain any Licensed Patents in the Territory for which it controls the prosecution and maintenance, including payment of maintenance fees or annuities on any such Licensed Patents, (ii) prosecute any corrections, substitutions, reissues, reviews, interferences and reexaminations of any Licensed Patents in the Territory, for which it controls the prosecution and maintenance, and file any other forms of patent term restoration in any applicable jurisdiction in the Territory, (iii) diligently defend any Licensed Patents for which it controls the prosecution and maintenance against any opposition, inter partes review, post-grant review or other proceeding before any Patent Office, and (iv) not disclaim or abandon, or fail to take any action necessary or desirable to prevent the disclaimer or abandonment, of any Licensed Patents in the Territory for which it controls the prosecution and maintenance. To the extent the Seller does not control the prosecution and maintenance obligations under Sections 15.3, 15.4 and 15.5 of the License Agreement, the Seller shall use commercially reasonable efforts to cause Licensee (or the Foundation, as applicable) to satisfy its prosecution and maintenance obligations thereunder and the Seller shall at its own expense exercise its consulting, request, consent, approval or similar rights, with such exercise to be reasonably determined by the Buyer after consultation with the Seller in the event the Buyer is the Control Party.

(e) Nothing in this Section 5.10 shall be construed to limit the Seller’s obligations pursuant to Section 5.5(a) while the Seller is the Control Party.

(f) The Proceeds resulting from any enforcement actions under Section 15.8 of the License Agreement shall be applied first to reimburse for any expenses incurred by the Seller and the Buyer in connection with such enforcement, and the remainder of the Proceeds shall be allocated between the Seller and the Buyer as though such Proceeds constituted Royalty payments; provided, however, that in the event that the Seller initiates an action pursuant to Section 15.8 of the License Agreement, the Seller shall promptly notify the Buyer of such action and the Proceeds of any such action shall be allocated between the Seller and the Buyer as though such Proceeds constituted Royalty payments only if the Buyer funds its Pro Rata Portion of the costs of such action.

Section 5.11 Additional Monetizations. The Seller agrees to notify the Buyer in writing at least [**] prior to entering into a definitive agreement with a Third Party to assign, convey, monetize, impose a Lien upon or otherwise transfer or encumber any or all of its retained interest in the Royalty (a “Definitive Monetization Agreement”). For the avoidance of doubt, nothing herein shall prevent or limit the ability of the Seller to enter into or consummate any such Definitive Monetization Agreement; provided, that, if the Seller is the Control Party, the Seller agrees that if any Definitive Monetization Agreement provides a Third Party with information rights that are more favorable than the information rights provided to the Buyer in this Agreement, the Seller shall provide the Buyer with information rights that are as favorable to the Buyer as those provided to such Third Party, and the Seller shall effect such amendments or modifications to this Agreement or execute such other documents as the Buyer may reasonable request to effect the foregoing and provided further, that, for the avoidance of doubt, nothing in this Section 5.11 shall in any way limit the Buyer’s rights pursuant to Section 5.5(a).

Section 5.12 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 5.13 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.

Section 5.14 Tax Matters.

(a) The Seller and Buyer shall treat the transactions contemplated by the Transaction Documents as a sale of the Assigned Royalty Payments for all United States federal state, local and non-U.S. Tax purposes. Accordingly, any and all Assigned Royalty Payments made after the Closing Date shall be treated as made to the Buyer for United States federal, state, local and non-U.S. Tax purposes.

(b) If there is a Permitted Withholding Tax Royalty Reduction, the Seller shall reasonably cooperate with, and assist, Buyer in delivering the prescribed forms necessary to reduce the applicable rate of, or to eliminate, withholding to the extent Buyer is entitled under any applicable tax treaty, in accordance with Section 13 of the License Agreement.

Section 5.15 Standstill. The Buyer agrees that during the term of this Agreement, or upon an earlier Standstill Termination, without the consent of the Seller, the Buyer shall not, and shall cause its Affiliates not to, (a) propose any merger, consolidation, business combination, tender or exchange offer or other business combination or change of control transaction involving all or substantially all of the Seller’s equity, businesses or assets, on a consolidated basis (a “Seller Business Combination”); (b) provide financing to any Third Party in connection with a Seller Business Combination; (c) propose or seek, whether alone or in concert with others, any “solicitation” (as such term is used in the rules of the Securities and Exchange Commission) of proxies or consents to vote any securities of the Seller; (d) nominate any person as a director of the Seller; (e) propose any matter to be voted upon by the stockholders of the Seller; (f) directly or indirectly, form, join or in any way participate in a Third Party “group” (as such term is used in the rules of the Securities and Exchange Commission) (or discuss with any Third Party the potential formation of a group) with respect to any securities of the Seller or a Seller Business Combination; provided that, for the avoidance of doubt, nothing in this Section 5.15 shall prohibit the Buyer from agreeing to purchase any pharmaceutical royalties from the Seller or any Third Party. The term “Standstill Termination” shall mean the earliest of (1) the public announcement that the Seller has entered into a definitive agreement with a Third Party for a Change of Control or a transaction involving a Seller Business Combination; (2) if any person(s) or “group” publicly announces or commences a tender or exchange offer to acquire voting securities of the Seller, that, if successful, would result in such person or group beneficially owning more than 50% of the then outstanding voting securities of the Seller; (3) if any person(s) or “group” commences a proxy contest with respect to the Seller and (4) if any person(s) or “group” files a Schedule 13D with respect to the beneficial ownership of at least [**]% of the then outstanding voting securities of the Seller by such person(s) or “group”.

(b) Notwithstanding the foregoing, in the event the Receiving Party is required to make a disclosure of the Disclosing Party’s Confidential Information pursuant to Sections 6.2(a)(i), (ii), (iii) or (iv), it will, except where impracticable, give reasonable advance notice to the Disclosing Party of such disclosure and use reasonable efforts to secure confidential treatment of such information. In any event, the Buyer shall not file any patent application based upon or using the Confidential Information of the Seller provided hereunder.
