3.1 Notification of Third Party Infringement. Each Party shall promptly notify the other Party in writing of any claim or evidence of possible Third Party infringement or misappropriation of any the Guanfacine Patents or Guanfacine Know-How insofar as such infringement or misappropriation relates to Guanfacine.

3.2 Right to Respond. Shire or its Affiliates shall have the first right, but not any obligation, to take any action against any infringement, misappropriation, or allegation of invalidity or unenforceability of any Guanfacine Patents insofar as such infringement, misappropriation, or allegation of invalidity or unenforceability relates to Guanfacine by a Third Party with counsel to be chosen by Shire or its Affiliates provided that, to the extent practicable and not materially detrimental to Shire, Shire notifies Supernus prior to its response and allows Supernus sufficient opportunity to contribute to such action if Supernus determines that Shire’s action will have an effect on other Supernus’ licensees. Shire shall also have the sole right, and at its sole discretion, to settle or compromise any such action in any manner. The expense and costs of counsel in such action by Shire shall be borne entirely by Shire. Supernus shall be permitted to retain its own counsel in an action by Shire at Supernus’ own expense and costs, and Shire shall have no obligation to reimburse Supernus for such expense or costs. If Shire does not take any action against such infringement, misappropriation, or allegation of invalidity or unenforceability of the Guanfacine Patents and Supernus chooses to act at its own election, the expense and costs of such action shall be borne entirely by Supernus, but Shire shall be permitted to retain its own counsel in such action at Shire’s own expense and costs and Supernus shall have no obligation to reimburse Shire for such expense or costs.

Supernus or its Affiliates shall have the sole right, but not any obligation, to take any action against any infringement, misappropriation, or allegation of invalidity or unenforceability of any Guanfacine Patents insofar as such infringement, misappropriation, or allegation of invalidity or unenforceability does not relate to Guanfacine by a Third Party with counsel to be chosen by Supernus or its Affiliates, provided that, to the extent practicable and not materially detrimental to Supernus, Supernus notifies Shire prior to its response and allows Shire sufficient opportunity to contribute to such action. Supernus shall also have the sole right, and at its sole discretion, to settle or compromise any such action in any manner. The expense and costs of counsel in such action by Supernus shall be borne entirely by Supernus. Shire shall be permitted to retain its own counsel in an action by Supernus at Shire’s own expense and costs, and Supernus shall have no obligation to reimburse Shire for such expense or costs.

Supernus shall not take any direct or indirect actions and shall not assist any Third Party or any Affiliate of Supernus in any action asserting that any Guanfacine Patent is invalid, is not enforceable, or is not infringed.

3.3 Recovery. Any and all monetary damages recovered from a Third Party in connection with any action by Shire regarding infringement, misappropriation, invalidity, or unenforceabilty of any of the Guanfacine Patents shall be used to reimburse Shire for the expense and costs of Shire’s counsel. Any excess over such reimbursement shall be treated as Net Sales under this Agreement. Any and all monetary damages recovered from a Third Party in connection with any action by Supernus regarding infringement, misappropriation, invalidity, or unenforceabilty of

any of the Guanfacine Patents shall be used to reimburse Supernus for the expense and costs of Supernus’s counsel. Shire shall receive the equivalent of the then applicable royalty rate payable by Supernus under Section 4.2of any excess over such reimbursement.

ARTICLE 4 — MILESTONE, ROYALTIES, AND REPORTING

4.1 Milestone and Milestone Payment. Shire shall, upon the First Commercial Sale in the United States of the first Licensed Product, pay to Supernus [**] dollars (US$[**]). This milestone payment shall accrue and be paid for the first Licensed Product only, and shall be made only once when this milestone is achieved for the first time under this Agreement regardless of how many times such milestone is achieved for the first Licensed Product. Shire shall pay any such milestone payment to Supernus within ten (10) Business Days of the date the payment becomes due. No payment shall be owed unless the milestone is achieved.

4.2 Royalty Rate on Licensed Products. During the Royalty Term (as defined in section 4.4, below) Shire shall pay to Supernus a running royalty of [**] ([**]%) of Net Sales of each Licensed Product that, absent this Agreement, would infringe a Valid Claim of a Guanfacine Patent in the country in which such Licensed Product is sold and that is not researched, developed, formulated, or manufactured for Shire or its Affiliates by or on behalf of Supernus. If the term of such Guanfacine Patent that would be infringed absent this Agreement expires during the Royalty Term for such Licensed Product, Shire shall pay to Supernus a running royalty of [**] ([**]%) of Net Sales of such Licensed Product for the remainder of the Royalty Term for such Licensed Product. The foregoing notwithstanding, no running royalties shall be due to Supernus under any Guanfacine Patents or Guanfacine Know-How assigned to Shire pursuant to Section 2.5.

4.3 One Royalty. Only one royalty shall be due for the Net Sales of any Licensed Product, no matter what Intellectual Property Rights are incorporated into such product. Furthermore, Shire’s obligation to pay royalties shall only be imposed once with respect to the same unit of a Licensed Product, no matter how many times that unit may be sold.

4.4 Royalty Term. Royalties due under this Article 4 will be due on a country-by-country until the later of (i) [**] or (ii) [**], absent this Agreement, would be infringed by the sale of such Licensed Product in such country (“the Royalty Term”). After expiration of the Royalty Term for any Licensed Product, the licenses granted in this Agreement shall become permanent, irrevocable, and fully paid-up with respect to such Licensed Product.

4.5 Payments. Shire shall within thirty (30) days following the conclusion of each Calendar Quarter after the First Commercial Sale of a Licensed Product for which a royalty is due, deliver to Supernus a written report showing the information and basis on which the payment under Section 4.2 due for such Calendar Quarter is calculated. Supernus shall within ten (10) days following the receipt of such information issue to Shire an invoice for the payment of such amount due under Section 4.2. Shire shall pay any amounts properly invoiced by Supernus within fifteen (15) days from the date of receipt of the invoice. Any such amounts shall be payable in United States dollars and shall be paid by bank wire transfer in immediately available

funds to such bank account as designated in writing by Supernus.

4.6 Payment Currency. If Net Sales are in a currency other than U.S. dollars, then, for the purpose of determining the amount of royalties payable hereunder, such amount shall be converted into U.S. dollars at the exchange rate used by Shire consistent with its standard operating procedures as they relate to its income statement, for the purposes of consolidating its own net revenues. Such policies will be made available to Supernus upon request and are consistent with customary industry practices.

4.7 Withholding Taxes. All amounts payable by Shire pursuant to this Agreement shall be paid free and clear of, and without deduction for and on account of, tax unless Shire is required by law to make those payments subject to deduction or withholding of tax, in which case Shire will deduct or withhold such taxes in accordance with the applicable tax treaty, law or regulation and will pay such taxes to the appropriate taxing authorities. Shire shall make certificates of such tax payments available to Supernus to review and copy.

4.8 Interest. Subject to Section 4.7, interest shall be chargeable on any amounts overdue to Supernus at the Agreed Rate, from the due date for payment of the unpaid sum to the date of actual payment of the full amount. The Agreed Rate for these purposes is the rate of [**] ([**]%) above the U.S. Federal Funds Rate from time to time, such interest to accrue daily and to be compounded on the last day of each calendar month.

4.9 Records and Audits. Shire, its Affiliates and its sublicensees shall keep and maintain complete and accurate records of their revenues received from sales of Licensed Product(s) for a period of three (3) years. Shire shall permit, and cause its Affiliates and sublicensees to permit, independent certified public accountants retained by Supernus and approved by Shire, such permission not to be unreasonably withheld or delayed, to have access to their records and books for the sole purpose of verifying Net Sales and any payment under Section 4.2 due thereon. Such independent certified public accountant must be under an obligation of confidentiality (a) not to use the information contained in the audited Party’s records and books or the auditing results for any other purpose and (b) not to disclose the information contained in the audited Party’s records and books or the auditing results except that the independent certified public accountant may disclose the auditing results to Supernus solely to confirm the accuracy of the information being audited and to identify any errors therein. The independent certified public accountant shall promptly forward the results of such audit to both Supernus and Shire upon completion of such audit. Such examination shall be conducted during regular business hours and upon reasonable notice and no more than once in each Calendar Year during the Term of this Agreement, and once during the Calendar Year following the termination of this Agreement and only for the two (2) Calendar Years preceding the date of such request for such audit. Any adjustment in the amount of payment under Section 4.2 due to Supernus on account of overpayment or underpayment of amounts due hereunder shall be made at the next date when payments are to be made under this Agreement. Supernus shall pay the fees and expenses of the accountant engaged to perform the audit unless such audit reveals an underpayment of [**] ([**]%) or more for the period examined, in which case the audited Party shall pay all reasonable fees and expenses of the accountant.

4.9 Legal Restrictions. If at any time legal restrictions prevent the remittance by Shire of all or any part of royalties on Net Sales in any country, Shire will have the right and option to make such payment by depositing the amount thereof in local currency to an account in the name of Supernus in a bank or other depository in such country. Shire will consult with Supernus regarding, and promptly notify Supernus of, any and all such arrangements.

4.10 Current Products. If there have been Net Sales of any product prior to or on the Effective Date, there shall be no royalties due to Supernus for any Net Sales of such product made after the Effective Date. For the avoidance of doubt, this Section 4.10 refers to all units of such product no matter when produced or sold.

4.11 Future Products. Shire has no obligation to Supernus or its Affiliates to make, use, offer to sell, sell, import, or commercialize any compounds or products under this Agreement, and therefore, there is no obligation or commitment to Supernus that any payments of any kind will ever accrue to Supernus under this Agreement. This Section 4.11 is not a grant of any license for Shire to make, use, offer to sell, sell, import, or commercialize any compounds or products under this Agreement.

For the avoidance of doubt and notwithstanding the immediately preceding sentence, this indemnity shall not include protection for any loss, claim, damage, or liability resulting, in whole or in part, directly or indirectly, from actions or omissions covered by the warranty disclaimers in Section 5.3 herein.

Supernus hereby agrees to defend, indemnify and hold harmless Shire and each of its Representatives from and against any Liabilities to the extent arising from Supernus’ or its Representatives’ wilful misconduct, gross negligence or material breach of its representations and warranties or its obligations under this Agreement, except, in each case, to the extent that such Liability arises, in whole or in part, as a result of Shire’s or its Representatives’ wilful misconduct, gross negligence, or breach of this Agreement. For the avoidance of doubt and notwithstanding the immediately preceding sentence, this indemnity shall not include protection for any loss, claim, damage, or liability resulting, in whole or in part, directly or indirectly, from actions or omissions covered by the warranty disclaimers in Section 5.3 herein.

5.5 Indemnification Procedure. The indemnified Party shall promptly notify the indemnifying Party, in writing, if it learns of any litigation, claim, administrative or criminal proceedings (collectively “Actions”) asserted or threatened against the indemnified Party for which the indemnified Party is entitled to indemnification hereunder. With respect to any such Action, the indemnified Party shall cooperate with and provide such assistance to the indemnifying Party as such Party may reasonably request. Such assistance may include providing copies of all relevant correspondence and other materials that the indemnifying Party may reasonably request; provided however, that any information so provided which is confidential shall be treated in accordance with the confidentiality provisions of the Ongoing Projects Agreement.

In the event of any claim or notice of the commencement of any proceedings to which the indemnities in this Article 5 may apply, the indemnified Party shall permit the indemnifying Party to take control of the relevant proceedings and shall not make any admission or offer or make any settlement without the prior consent of the indemnifying Party. If the indemnifying Party shall assume the control of the relevant proceedings in accordance with the previous sentence, (a) the indemnifying Party shall obtain the prior written consent of the indemnified Party before entering into any settlement with respect to such proceedings if the settlement would not release the indemnified Party from all liabilities and obligations with respect to such proceedings or the settlement would impose injunctive or other equitable relief against the indemnified Party and (b) the indemnified Party shall be entitled to participate in such proceedings and to employ separate counsel of its choice for such purpose. The fees and expenses of such separate counsel shall, absent a conflict between the indemnifying Party and the indemnified Party, be paid by the indemnified Party. The failure or delay to deliver notice to the indemnifying Party within a reasonable time after the commencement of any such action, if irreparably prejudicial to the indemnifying Party’s ability to defend such action, shall relieve the

indemnifying Party of any liability to the indemnified Party under this Article 5 to the extent that is directly attributable in its entirety to such failure or delay, but the omission to deliver notice to the indemnifying Party will not relieve the indemnifying Party of any liability that the indemnifying Party may have to any indemnified Party otherwise. The indemnified Party shall cooperate fully with the indemnifying Party and its legal representatives in the investigation of any loss, action, claim, damage, or liability covered by this indemnification.

5.6 Compliance with Law. Each Party shall comply, and shall require its Affiliates and sublicensees to comply, with all applicable laws and regulations relative to its obligations hereunder.

To the extent that a Party has or hereafter may acquire any immunity from jurisdiction of any court or from any legal process (whether through service of notice, attachment prior to judgment, attachment in aid of execution or execution, on the ground of sovereignty or otherwise) with respect to itself or its property, it hereby irrevocably waives, to the fullest extent it may legally and effectively do so, such immunity in respect of its obligations under this Agreement.

Supernus shall have the right to assign, transfer, or charge its rights and obligations in their entirety under this Agreement without the consent of Shire only as part of a sale of the entire assets of Supernus to a single Third Party, and only if such assignment, transfer, or charge is to such single Third Party, such assets including all of those acquired by Supernus under the Transaction Documents.

8.4 Force Majeure. Neither Party shall be held liable or responsible to the other Party nor be deemed to have defaulted under or breached this Agreement for failure or delay in fulfilling or performing any term of this Agreement when such failure or delay is caused by or results from causes beyond the reasonable control of the affected Party, including without limitation, fire, floods, embargoes, war, acts of war (whether war is declared or not), insurrections, riots, civil commotions, strikes, lockouts or other labor disturbances, acts of God or acts, omissions or delays in acting by any governmental authority or the other Party; provided, however, that the Party so affected shall use commercially reasonable and diligent efforts to avoid or remove such causes of non-performance, and shall continue performance hereunder with reasonable dispatch wherever such causes are removed.

The Parties shall mutually seek a resolution of the delay or the failure to perform in good faith.

8.5 Waivers and Modifications. The failure of any Party to insist on the performance of any obligation hereunder shall not be deemed to be a waiver of such obligation.
