For clarity, once Purchaser has paid the Purchase Price, Purchaser fully owns all Purchased Assets listed in Section 1.2 together with all Assumed Liabilities (mutatis mutandis).

1.8Milestone Payments.

(a)Within [*****] days after the achievement of a development milestone or sales milestone event listed below (each such event, a “Milestone Event”), whether achieved by Purchaser, an Affiliate, licensee or other Permitted Selling Party, Purchaser shall notify Seller in writing that such Milestone Event has been achieved and shall pay Seller the milestone payment corresponding to the applicable Milestone Event (each, a “Milestone Payment,” and, collectively, the “Milestone Payments”) by wire transfer of immediately available funds to an account designated by Seller, as follows:

(b)All Milestone Payments that become due and payment in accordance with Section 1.8(a) shall be made in accordance with this Section 1.8(b). Each Milestone Payment shall be payable [*****], for the first achievement of the corresponding Milestone Event. In the event that Purchaser achieves a later Development Milestone before an earlier Development Milestone (for example, because development can be accelerated), Purchaser shall make the payment associated with the earlier Development Milestone when it makes the payment associated with the later Development Milestone. At Purchaser’s discretion and subject to applicable Securities Laws, Purchaser may issue Shares in lieu of cash for up to [*****] ([*****]%) of each Milestone Payment.

For clarity, Purchaser’s payment obligation with respect to the foregoing Development Milestones and Sales Milestones for each Future Product shall apply only with respect to the [*****] Future Products. Purchaser shall have no obligation to make

1 Development and Sales Milestones for Existing Products are limited to payments for the first approved product, DRX-164 or a Combination Product with DRX-164.

any Milestone Payments with respect to any Product other than one Existing Products and the [*****] Future Products.

1.9Royalty Payments.

(a)Purchaser shall pay tiered royalties on aggregate worldwide Net Sales of all Products sold by Purchaser, its Affiliates and other Permitted Selling Parties each Calendar Year at the following rates (each, a “Royalty Payment,” and, collectively, the “Royalty Payments”), as follows:

(b)Royalty Payments will be payable on a Product-by-Product and country-by-country basis with respect to all Products sold in such country from the First Commercial Sale of such Product sold in such country until the latest of (i) [*****] years after the First Commercial Sale of the such Product and (ii) the expiration of the last to expire Valid Claim of a Composition of Matter Patent covering such Product (each, a “Royalty Term”).

(c)All Royalty Payments shall be made in U.S. Dollars. If any currency conversion is required in connection with Royalty Payments due to Seller hereunder, Purchaser will convert the amount into U.S. Dollars at an exchange rate equal to the [*****] of U.S. Dollars published in the East Coast Edition of The Wall Street Journal for the last business day of the applicable reporting period. If at any time legal restrictions prevent the prompt remittance of all or part of any Royalty Payments owed by Purchaser hereunder with respect to any country, Purchaser will pay the Royalty Payments owed to Seller (as converted into U.S. Dollars) directly from its United States sources of fund for as long as the legal restrictions apply.

(d)Within [*****] days after the last day of each Calendar Quarter, Purchaser shall provide to Seller a true and accurate report setting out in reasonable detail (on a country-by-country basis) the information necessary to calculate Royalty Payments due hereunder with respect to Net Sales of the Products during such Calendar Quarter, including: (i) aggregate gross sales of the Products in the relevant Calendar Quarter; (ii) Calendar Year-to-date aggregate gross sales of the Products; (iii) aggregate Net Sales of the Products in the relevant Calendar Quarter, including category-by-category details of deductions from aggregate gross sales to arrive at Net Sales; (iv) Calendar Year-to-date aggregate Net Sales of the Products, including category-by-category details of deductions from aggregate gross sales to arrive at Net Sales; (v) the applicable exchange rate (determined in accordance with Section 1.9(c) used to calculate such amounts, and (vi) the date of First Commercial Sale of any of the Products in any country first occurring during such Calendar Quarter. In addition, Purchaser shall provide in a timely fashion as Seller may reasonably request such other information and reports as requested by Seller to confirm the Royalty Payment calculation.

(e)Simultaneously with the delivery of each report under Section 1.9(d), Purchaser shall pay to Seller the total Royalty Payments due under Section 1.9(a) for the period covered by such report. For clarity, Purchaser’s payment obligation with respect to the Net Sales of each Future Product shall apply only with respect to the [*****] Future Products. Purchaser shall have no obligation to make any Royalty Payments with respect to any Product beyond the Existing Products and the [*****] Future Products.

(f)Generic Competition. Subject to Section 1.9(h), on a Product-by-Product and country-by-country basis, the royalty rates set forth in Section 1.9(a) applicable to such Product in such country in a given Calendar Quarter will be reduced by [*****]%, if during such Calendar Quarter during the Royalty Term, (i) Net Sales of such Product decline by [*****] percent ([*****]%) or more relative to the average Net Sales of such Product in such country for the [*****] Calendar Quarters immediately preceding the Calendar Quarter in which the Generic Equivalent Product is launched in such country, or (ii) the aggregate number of units of Generic Equivalent Products with respect to such Product sold during such Calendar Quarter in such country is [*****] percent ([*****]%) or more of the aggregate units of the sum of all such Generic Equivalent Products and such Product sold in such Calendar Quarter in such country. All determinations of the units of Generic Equivalent Products and Product sold in a country shall be based on a mutually acceptable calculation method using data obtained from a reputable and mutually agreed Third Party source, such as IQVIA. For clarity, the reduction under this Section 1.9(f) shall only apply in the Calendar Quarter(s), if any, in which (A) the aggregate number of units of Generic Equivalent Products with respect to a Product sold during the Calendar Quarter in a country exceeds [*****]% of the aggregate units of the sum of all such Generic Equivalent Products and such Product sold in such Calendar Quarter in such country or (B) Net Sales of such Product are equal to or less than [*****] ([*****]%) of the average Net Sales of such Product in such country for the [*****] Calendar Quarters immediately preceding the Calendar Quarter in which the Generic Equivalent Product is launched in such country.

(g)Right to Set Off. If (i) Purchaser reasonably and in good faith determines it is necessary to license any Blocking Third Party IP in order to avoid infringing or misappropriating such Blocking Third Party IP by the making, using, selling, offering for sale or importation of the Compound contained in a Product, and (ii) Purchaser is required to pay to such Third Party any Blocking Third Party IP Costs, then, subject to Section 1.9(h) and solely with respect to the Product in the country that is subject to the Blocking Third Party IP and Blocking Third Party IP Costs, for the period during which Purchaser owes royalties to Seller hereunder with respect to such Product in such country, the royalties that would otherwise be payable on Net Sales of such Product in such country for a Calendar Quarter shall be reduced by an amount up to [*****] ([*****]%) of the Blocking Third Party IP Costs paid by or on behalf of Purchaser to such Third Party to the extent applicable to such Product in such country during such Calendar Quarter; provided, however, that in no event will the royalties that would otherwise be payable to Seller hereunder (after any applicable reduction pursuant to Section 1.9(f)) with respect to such Product in such country be reduced by more than [*****]% in any given Calendar Quarter as a result of any deduction under this Section 1.9(g); and provided further, that Purchaser will be entitled to carry forward to subsequent Calendar Quarters any amounts with respect to which Purchaser would have been entitled to make a deduction pursuant to this Section 1.9(g) but is unable to take such deduction pursuant to the first proviso in this Section 1.9(g).

(h)Cumulative Reductions Floor. Notwithstanding anything to the contrary herein, in no event shall the cumulative effect of the adjustments in Section 1.9(f) and Section 1.9(g) in any given Calendar Quarter reduce the royalties payable to Seller hereunder to less than [*****]% of the amounts that otherwise would have been payable to Seller hereunder (without taking into consideration any such adjustments) in such Calendar Quarter.

1.10Withholding. Purchaser shall be entitled to deduct and withhold all Taxes that Purchaser is required by applicable Law to deduct and withhold and actually deducts and withholds in accordance with any provision of applicable Law. All such withheld amounts shall be treated as delivered to Seller hereunder. Purchaser will notify Seller of such withholding and will furnish Seller with copies of any tax certificates or other documentation evidencing such withholding within [*****] days after remittance. Each Party shall provide to the other Party any tax forms that may be reasonably necessary in order for Purchaser not to withhold tax or to withhold tax at a reduced rate under any applicable income tax treaty. The Parties agree to cooperate with one another and use reasonable efforts to avoid or reduce tax withholding or similar obligations in respect of any payment made by Purchaser to Seller hereunder. Notwithstanding the foregoing, in no event will the payments due to Seller hereunder be reduced as a result of Purchaser’s assignment or transfer of this Agreement, change in the residence of Purchaser for tax purposes, change in the entity making such payment, or failure on the part of Purchaser to comply with applicable Laws or filing or record retention requirements, and in the event of any such action, the sum payable by Purchaser to Seller shall be increased to the extent necessary to ensure that Seller receives a sum equal to the sum that Seller would have received had no such action occurred.

1.11Late Payments. Purchaser shall pay interest on any overdue payments from the due date until the date of payment at an annual rate of one and [*****] percent ([*****]%) per month or the maximum rate allowed by applicable Law, whichever is less.

enforceability or validity of any Transferred IP or other Exploitation of the Compound, Products or the Purchased Assets as currently being conducted. As of the Signing Date, no Transferred Patent is involved in any nullity, inter partes or interference, opposition, reissue, reexamination, revocation, or equivalent proceeding, in which the inventorship, scope, validity or enforceability of any such Transferred Patent is being or has been contested or challenged, and to Seller’s Knowledge, no such proceeding has been threatened with respect to any Transferred Patent.

(iii) Seller has not received any written notice asserting that any Transferred IP or the use, development, manufacture, sale, offering for sale, licensing, or distribution of any Transferred IP or any Product directly or indirectly via contribution or inducement infringes or could infringe the rights of any Third Party;

(iv) since [*****] there has not been, and currently there is no asserted, pending or, there has not been since any threatened written action, proceeding, or other claim that a current or former employee, officer or director of Seller (each, a “Seller Representative”) misappropriated or infringed any intellectual property rights of any Person that had previously employed or otherwise engaged such Seller Representative in relation to the development of the Products or Transferred IP; and

(v)Seller has not received any written notice or written offer from any Third Party offering a license under any Third Party patents for the purpose of avoiding a claim that such patents would be infringed by the use, manufacture, sale, offering for sale, or importation of any Transferred IP or any Product.

(k)To the Seller’s Knowledge, no Person has infringed or misappropriated in the past or is currently infringing or misappropriating any Transferred IP.

(l)Seller has taken reasonable security measures to protect the secrecy, confidentiality, and value of all Know-How relating to the Compound that Seller maintains as Trade Secrets owned by Seller (“Compound-Related Trade Secrets”), including requiring each officer, employee, consultant and contractor of Seller (in each case who is employed by Seller or is engaged by and under contract with Seller) having access to Compound-Related Trade Secrets since [*****] to execute a confidentiality agreement. Further, there has not been any breach of such confidentiality agreements by any such officer, employee, consultant or contractor of Seller. No employee, officer, director, consultant or contractor of Seller (in each case who is employed by Seller or is engaged by and under contract with Seller) with access to any Compound-Related

Trade Secrets since [*****] has any right, license, claim or interest whatsoever in or with respect to any Purchased Assets.

(m)Seller’s standard practices are to have each employee, officer, consultant, contractor or any other person who developed for or on behalf of Seller or any of its Affiliates any part of any Transferred IP (in each case who is, or since [*****] has been, employed by Seller or is, or since [*****] has been, engaged by and under contract with Seller) enter into a binding written agreement that conveys or obligates such person to convey, by a present, irrevocable assignment, to Seller or any of its Affiliates any and all right, title and interest in and to all Transferred IP developed by such person in connection with such person’s employment with or engagement by Seller or any of its Affiliates. Seller has provided Purchaser with true and complete copies of all such agreements by or on the Closing Date in the virtual data room or otherwise.

(n)Seller has no Knowledge that it is or will be necessary for Seller or any of its Affiliates to utilize any inventions of any of its or their employees made prior to or outside the scope of their employment by Seller or any of its Affiliates which have not been or will not be assigned to Seller or any of its Affiliates, in order for Purchaser to Exploit the Compound or Products or the Purchased Assets as currently being developed by Seller.

(o)Seller has not received any notice that any employee of Seller (i) has been or is in violation of any term or covenant of any employment contract, patent disclosure agreement, invention assignment agreement, nondisclosure agreement, noncompetition agreement or any other contract with any Third Party by virtue of such employee being employed by, or performing services for Seller or using trade secrets or proprietary information of any Third Party without permission; and (ii) has developed any technology underlying the Transferred IP that is subject to any contract under which such employee has assigned or otherwise granted to any Third Party any rights (including intellectual property rights) in or to such technology.

(p)No funding or grants from, or facilities of, a Governmental Body or institution, university, college or other academic or educational institution or research center, was used by Seller or any of its Affiliates in the development of the Transferred IP. To the Seller’s Knowledge, no employee, consultant or independent contractor of Seller who was involved in or contributed to the creation or development of any Purchased Assets has performed services for the government, for a university, college or other educational institution or for a research center during the same period of time during which such employee, consultant or independent contractor was also performing services relating to the creation or development of any Purchased Assets for Seller.

(a)Seller has complied, and is now complying, in all material respects with all applicable international federal, state and local laws applicable to Seller’s ownership and use of the Purchased Assets. Seller represents that neither it nor any of its Affiliates nor any other Person has received any inspectional observations, establishment inspection reports, untitled letters, warning letters and/or any other material documents from any Regulatory Authority with respect to the Products since [*****], and that arise from a lack of compliance, in any material respect, with any applicable Laws.

(b)In relation to Seller’s research and development of the Products, Seller has not (i) made an untrue statement of a material fact or fraudulent statement to any Governmental Body, (ii) failed to disclose a material fact required to be disclosed to any Governmental Body, (iii) committed any other act, made any statement or failed to make any statement, that (in any such case) establishes, or would have established at the time such statement was made, a reasonable basis for the FDA to invoke its Fraud, Untrue Statements of Material Facts, Bribery, and Illegal Gratuities Policy or any Governmental Body to invoke any similar Law. In relation to the Compound, Seller is not the subject of any pending or threatened investigation by the FDA pursuant to its Fraud, Untrue Statements of Material Facts, Bribery, and Illegal Gratuities Policy or any Governmental Body to invoke any similar Law.

4.1Tax Treatment and Purchase Allocation.

(a)The Parties and their Affiliates agree to treat the Transactions contemplated by this Agreement as a sale of the Seller’s business and its assets for U.S. federal, state and other applicable tax purposes. The Parties and their Affiliates shall file all applicable Tax Returns consistent with the foregoing, and shall not take any contrary position in any Tax Return except to the extent required by applicable Laws. The Parties agree to cooperate in providing any information requested by another Party relating to the filing of Tax Returns and other tax-related matters.

(b)As soon as practicable after the Signing Date, Seller will provide Purchaser with an allocation of the payments to be made by Purchaser to Seller under this Agreement among the assets transferred under this Agreement in accordance with Section 1060 of the Internal Revenue Code of 1986, as amended (“Code”), and the Treasury Regulations thereunder for Purchaser’s review and comment. Seller will consider in good faith any reasonable comments of Purchaser. Seller and Buyer will, and will cause their respective Affiliates to, act in accordance with such allocation in the preparation, filing and audit of any Tax Return except to the extent required by applicable Laws. Seller shall revise the allocation, and consider in good faith any reasonable comments of Purchaser to the revision, to reflect any adjustments to the Purchase Price pursuant to Section 4.2.

4.2Installment Sale Treatment. The Parties agree that the Milestone Payments, including any Milestone Payments paid in Shares, shall be treated in accordance with Law,

including, for the avoidance of doubt, as deferred contingent purchase price eligible for installment sale treatment under Section 453 of the Code and any corresponding provision of state, foreign or other applicable tax Laws. Any portion of the Milestone Payments received in Shares shall be treated as an amount of the Purchase Price equal to the fair market value of the Shares on the date of receipt. If and to the extent that any Milestone Payments are made, interest may be imputed on such amounts as required by Section 483 or 1274 of the Code. The Parties and their affiliates shall file all applicable Tax Returns consistent with the foregoing, and shall not take any contrary position in any Tax Return except to the extent required by applicable Laws.

4.3Tax Proration. Liability for all Taxes determined on an annual or periodic basis, including for tangible personal property or other similar Taxes (but excluding, for the avoidance of doubt, Transfer Taxes which shall be apportioned in accordance with Section 4.10), if any, attributable to the Purchased Assets or the Assumed Liabilities will be prorated between Seller and Purchaser as of the Closing Date, with Seller liable to the extent such items relate to any time period ending before the Closing Date and Purchaser liable to the extent such items relate to periods beginning on or after the Closing Date. For purposes of the preceding sentence, the amount of such Taxes that are allocable to Sellers shall be deemed to be the amount of such Taxes for the entire taxable period multiplied by a fraction, the numerator of which is the number of days in such taxable period ending on the day prior to the Closing Date and the denominator of which is the number of days in the entire taxable period.

4.4Cooperation; Transfer. Promptly following the Closing Date, each of Seller and Purchaser shall cooperate with the other Party and its employees, legal counsel, accountants and other representatives and advisers in connection with the steps required to be taken as part of their respective obligations under this Agreement, including, but not limited to, cooperation reasonably necessary to explain and transfer knowledge and practice related to Transferred Know-How and Trade Secrets and as is reasonably necessary for the preparation and filing of any Tax Return, for the preparation for any Tax audit, for the preparation for any Tax protest, or for the prosecution or defense of any suit or other proceeding relating to Tax matters; and each of them shall, from time to time after the Closing Date, upon the reasonable request of the other, do, execute, acknowledge and deliver, or cause to be done, executed, acknowledged and delivered, all such further acts, deeds, assignments, transfers, conveyances, receipts, acknowledgments, acceptances and assurances as may be reasonably required (without incurring unreimbursed expense) in order to consummate the Transactions on the terms and subject to the conditions set forth herein.

(a)Without limiting the foregoing, Seller and Purchaser shall cooperate to complete the transfer of the Transferred Records and Transferred Materials to Purchaser as soon as practicable on or after the Closing Date or the Transfer Date. Seller shall use commercially reasonable efforts to transfer those Transferred Records that Seller is able to deliver or make available electronically within [*****] Business Days following the Closing Date and to transfer those Transferred Records that are not available electronically in hard copy format, to the extent original records are in Seller’s possession or control, within [*****] days following the Closing Date, and, in any event, the Parties will cooperate and use commercially reasonable efforts to transfer all tangible Purchased Assets to Purchaser no later than [*****] days after the Closing Date. The Parties shall cooperate to mutually agree on an arrangement to transfer the tangible Purchased Assets, including transportation method of the tangible Purchased Assets, storage of the Purchased Assets, and schedule. Seller will work with Purchaser to optimize the Existing Products’ manufacturing process and undertake a technology transfer of the manufacturing process required, including any related Know-How and Third-Party contracts, to make such Product (and any other related compounds) to enable Purchaser to manufacture additional preclinical, clinical and commercial supply of such Product (the “Manufacturing Tech

Transfer”). Purchaser will have all final decision-making authority and be responsible for preclinical, clinical and commercial supply, at its own expense, of all Products.

(b)The delivery of any physical materials shall be EXW (Incoterm 2010) Seller’s or its designee’s facility. For clarity, Purchaser shall be responsible for all costs and expenses of delivery.

4.5Governmental Filings. Seller and Purchaser each agree to prepare and file whatever filings, requests or applications are required to be filed with any Governmental Body in order to consummate the Transactions and to cooperate with one another as reasonably necessary to accomplish the foregoing, including filing notifications with the FDA and other Regulatory Authorities as necessary in order to transfer Regulatory Documents to Purchaser as contemplated hereunder. Each Party shall bear its own costs of such filings, requests, or applications.

4.6Compliance with Law; Regulatory Documents. Purchaser will comply with all applicable Laws relating to its development, manufacture, distribution, marketing, promotion, selling, importing, exporting and other Exploitation of the Compound and Products. Purchaser acknowledges and agrees that after transfer, as holder of the Regulatory Documents, it will have sole responsibility for all regulatory reporting and Regulatory Document maintenance obligations, including, among other things, for adverse event reporting. Until the transfer of Regulatory Documents from Seller to Purchaser is completed, Purchaser and Seller shall give prompt notice to the other Party upon becoming aware of any action by, or notification or other information which it receives (directly or indirectly) from, any Governmental Body (together with copies of correspondence related thereto), which raises any material concerns regarding the safety or efficacy of the Products, or indicates or suggests a reasonably likely potential material liability for either Party to Third Parties arising in connection with the Products.

4.7Audit. Purchaser shall keep, and shall cause its Affiliates, licensees and other Permitted Selling Parties to keep (as applicable), full and complete books, records and accounts of its activities related to Exploitation of Products, including those related to achievement of Milestone Events, calculations of gross sales and Net Sales, and the calculation of Royalty Payments payable to Seller, as well as full and complete records relating to Purchaser’s rights and obligations under this Agreement. Purchaser shall maintain all such records for at least [*****] years after creation (or such longer period as required by applicable Law). Seller may [*****] in any Calendar Year, upon prior notice of [*****] week to Purchaser, cause an audit of the records maintained by Purchaser to be made by an independent accountant selected by Seller and reasonably acceptable to Purchaser. Such accountant shall have access, during regular business hours, to examine and inspect the records of Purchaser and its Affiliates, licensees and other Permitted Selling Parties (as applicable) pertaining to this Agreement for the purposes of this Section 4.7. If any report(s) provided or any payments paid or payable to Seller under this Agreement are found to be inaccurate, there shall be an adjustment and Purchaser shall pay to Seller (or vice versa) such sums as may be necessary to settle in full the accurate amount of such payments that should have been paid to Seller for the period or periods covered by such audit, together with interest charges pursuant to Section 1.11. If any such audit discloses an inaccuracy reflecting an under-reporting and/or underpayment of greater than [*****] percent ([*****]%) for the period of the audit report, then Purchaser also shall pay to Seller the cost of such audit, within [*****] days of such audit; otherwise the cost of such audit shall be paid by Seller. Any information received by Seller or its accountant under this Section 4.7 shall be subject to the confidentiality provisions of this Agreement.

4.8Sublicenses. Purchaser shall be entitled, without the prior consent of Seller, to grant one or more sublicenses to Third Parties (with the right to sublicense through multiple tiers); provided, however, that as a condition precedent to and requirement of any such sublicense: (a) any such sublicense shall be consistent with and subject to the terms and

conditions of this Agreement; and (b) Purchaser shall continue to be responsible for full performance of Purchaser’s obligations under this Agreement and will be responsible for all actions of such sublicensee.

4.9Purchaser Diligence. After the Closing, Purchaser shall have sole decision-making authority over the development, registration, manufacture, commercialization and other Exploitation of Products; provided that, Purchaser shall, and shall cause its Affiliates, licensees, sublicensees and other Permitted Selling Parties, as applicable, to, use Commercially Reasonable Efforts to develop, obtain Marketing Approval of, manufacture and commercialize at least one Product worldwide, including in the United States and the European Union. Except as expressly set forth in this Agreement, Purchaser will have no liability whatsoever to Seller in the event any Milestone Event does not occur.

4.10Insurance. Purchaser will maintain insurance with credit worthy insurance companies or self-insured in accordance with applicable Laws against risks from claims for damage to property or for bodily injury, including the death of any person, which may arise from Purchaser use of the Purchased Assets.

4.11Transfer Taxes. All sales, use, value added, transfer, stamp, registration, documentary, conveyance, recording, or other taxes applicable to the Transactions (“Transfer Taxes”) shall be paid by Purchaser, and Purchaser will be responsible for bearing and paying any and all Transfer Taxes that may become payable in connection with the sale and purchase of, payment for, delivery of, or transfer of title to the Purchased Assets to Purchaser pursuant to this Agreement. Purchaser shall file all necessary Tax Returns and other documentation required to be filed by it under applicable Law with respect to all Transfer Taxes, and, if required by applicable Law, Seller will join in the execution of any such tax returns and other documentation. Purchaser and Seller shall cooperate in providing each other with any appropriate resale exemption certifications and other similar documentation required to obtain any exemption from (or reduction in) Transfer Taxes.

4.12Recordation of Transferred Patents. Purchaser shall be responsible, at its sole cost and expense, for all applicable recordations of the assignment of the Transferred IP. Purchaser shall promptly file such documents with the U.S. Patent and Trademark Office and with foreign patent offices or other registrars as are necessary to record the assignment of the Transferred IP to Purchaser.

4.13Covenants Regarding Transfer of this Agreement or the Purchased Assets. Purchaser agrees to impose the relevant obligations of this Agreement on any acquirer, licensee, sublicensee or assignee (including any Affiliate-assignee or third party-assignee) of any or all of the Purchased Assets, which obligations shall include, without limitation, Sections 1.8 and 1.9. Without limiting the foregoing, any such acquirer or assignee shall expressly assume in writing all of the obligations of Purchaser under this Agreement.

5.1Non-Clinical and Clinical Development Services. Contemporaneous with the execution of this Agreement, Seller and Purchaser shall enter into a R&D Services Agreement, in a form substantially similar to the agreement attached hereto as Exhibit B, which sets forth the terms and conditions upon which Seller will provide the Services to Purchaser, including the implementation and performance of a Non-Clinical and Clinical Development Scope of Work (the “Non-Clinical and Clinical Development SOW”).

(a)Project Representatives. Within [*****] calendar days of the Signing Date, each Party shall appoint a project representative (each a “Project Representative”) who will have primary responsibility for day-to-day interactions with the other Party’s Project Representative concerning the Services. Unless otherwise mutually agreed by the Parties in writing, all communications between the Parties regarding the activities of the Parties in connection with this Agreement shall be addressed to, placed in copy, or routed directly through (as appropriate) the respective Project Representatives of each Party. If either Party changes its appointed Project Representative it will promptly notify the other Party in writing.

(b)Development Committee. Upon execution of this Agreement, the Parties shall establish a development committee (the “Development Committee”) comprised of representatives of each Party, which will consist of Project Representatives and other functional leaders with experience in the development and manufacturing of small molecule products. The Development Committee shall be responsible for overseeing and directing the Parties’ interaction and performance of their respective obligations under this Agreement and the Non-Clinical and Clinical Development SOW. [*****]. The Development Committee shall meet as often as necessary at mutually acceptable times and locations but at least on a [*****] basis. Such meetings may be in person or by telephone as agreed by the Development Committee. The Development Committee is not empowered to amend the terms of this Agreement, cause a Party to make financial commitments or take on additional obligations over its objection, or to expand its scope of authority or to determine any issue before the Development Committee in a manner that would conflict with the express terms and conditions of this Agreement.

6.1Indemnification by Seller. Subject to the other provisions of this Section 6, following the Closing, Seller shall defend, indemnify and hold harmless Purchaser and its Affiliates and their respective directors, officers, agents, representatives, successors, permitted assignees and employees (collectively, the “Purchaser Indemnitees”) from and against any and all Damages incurred as a result of or arising out of any claim, suit, action, demand or other proceeding made or brought against one (1) or more Purchaser Indemnitees to the extent resulting from: :

(a)any Excluded Liabilities or Excluded Assets;

(f)any inaccuracy in or breach of any representation or warranty made by Seller in this Agreement; and/or

(g)any breach or nonfulfillment by Seller of any of its covenants, obligations or agreements contained in this Agreement.

Provided that, Seller shall have no obligation to indemnify, defend or hold harmless any Purchaser Indemnitee to the extent any Damages are indemnifiable by Purchaser pursuant to Section 6.2.

6.2Indemnification by Purchaser. Subject to the other provisions of this Section 6, following the Closing, Purchaser shall defend, indemnify and hold harmless Seller and its Affiliates and their respective directors, officers, agents, representatives, permitted successors, permitted assignees and employees (collectively, the “Seller Indemnitees”) from and against any and all Damages incurred as a result of or arising out of any claim, suit, action, demand or other proceeding made or brought against one (1) or more Seller Indemnitees to the extent resulting from:

(a)any Assumed Liabilities;

(b)any Lien (other than Permitted Liens) placed on any Purchased Assets after the Closing Date;

Provided that, Purchaser shall have no obligation to indemnify, defend or hold harmless any Seller Indemnified Party to the extent any Damages are indemnifiable by Seller pursuant to Section 6.1.

6.3Third-Party Claims.

(a)In the event any Indemnified Party becomes aware of a Third-Party Claim (including any action or proceeding commenced or threatened to be commenced by any Third Party) that the Indemnified Party reasonably believes may give rise to the Indemnifying Party’s obligation to indemnify pursuant to either Section 6.1 or Section 6.2 (any such claim, a “Third-Party Claim”), the Indemnified Party shall promptly notify the Indemnifying Party in writing of such Third-Party Claim (such notice, the “Claim Notice”). The Claim Notice shall be accompanied by copies of any relevant and material documentation submitted by the Third Party making such Third-Party Claim and shall describe in reasonable detail (to the extent known by the Indemnified Party) the facts constituting the basis for such Third-Party Claim and the amount of the claimed Damages; provided, however, that no delay or failure on the part of the Indemnified Party in delivering a Claim Notice shall relieve the Indemnifying Party from any liability hereunder except and only to the extent the Indemnifying Party shall have been actually and materially prejudiced as a result of such delay or failure.

(b)Within [*****] Business Days after receipt of any Claim Notice, the Indemnifying Party may, upon written notice thereof to the Indemnified Party, assume control of the defense of the Third-Party Claim referred to therein at the Indemnifying Party’s sole cost and expense with counsel reasonably satisfactory to the Indemnified Party. Notwithstanding anything to the contrary contained herein, the Indemnifying Party shall not be entitled to assume

or control the investigation, defense or prosecution of such Third-Party Claim if (i) a material portion of the Damages associated with such Third-Party Claim are not reasonably expected to be indemnifiable hereunder, (ii) at the time of assumption or thereafter, the Indemnifying Party fails to conduct the investigation, defense or prosecution actively and diligently, or (iii) such Third-Party Claim seeks non-monetary, equitable or injunctive relief against the Indemnified Party or alleges any violation of Law by the Indemnified Party; and in each such case ((i), (ii) or (iii)), the Indemnified Party may assume control of its defense.

(c)The Party not controlling the defense of such Third-Party Claim (the “Non-Controlling Party”) may participate therein at its own expense; provided, however, that if the Indemnifying Party assumes control of the defense of such Third-Party Claim and the Indemnifying Party and the Indemnified Party have materially conflicting interests or different defenses available with respect to such Third-Party Claim which cause the Indemnified Party to hire its own separate counsel with respect to such proceeding, the reasonable fees and expenses of counsel to the Indemnified Party shall be considered “Damages” for purposes of this Agreement. The Party controlling the defense of such Third-Party Claim (the “Controlling Party”) shall keep the Non-Controlling Party advised, in writing, of the status of such Third-Party Claim and the defense thereof and shall consider in good faith recommendations made by the Non-Controlling Party with respect thereto. The Non-Controlling Party shall furnish the Controlling Party with such information as it may have with respect to such Third-Party Claim (including copies of any summons, complaint or other pleading which may have been served on such Party and any written claim, demand, invoice, billing or other document evidencing or asserting the same) and shall otherwise cooperate with and assist the Controlling Party, as reasonably requested by the Controlling Party, in the defense of such Third-Party Claim.

(d)The Indemnifying Party shall not agree to any settlement of, or the entry of any judgment arising from, any Third-Party Claim without the prior written consent of the Indemnified Party, which shall not be unreasonably withheld or delayed; provided, however, that the consent of the Indemnified Party shall not be required with respect to any such settlement or judgment if (i) such settlement or judgment (A) involves no admission of wrongdoing by the Indemnified Party, and (B) the sole relief provided is monetary Damages, and (ii) the Indemnifying Party agrees in writing to pay or cause to be paid any amounts payable pursuant to such settlement or judgment and such settlement or judgment includes a complete release of the Indemnified Party and its Affiliates, directors, officers, employees and representatives from further liability. Whether or not the Indemnifying Party shall have assumed the defense of a Third-Party Claim, the Indemnified Party shall not admit liability with respect to, or agree to any settlement of or the entry of any judgment arising from, any such Third-Party Claim without the prior written consent of the Indemnifying Party, which shall not be unreasonably withheld or delayed; provided, however, that the consent of the Indemnifying Party shall not be required with respect to any such settlement or judgment if the Indemnified Party agrees in writing to pay or cause to be paid any amounts payable pursuant to such settlement or judgment and that no Indemnified Party is entitled to indemnification under this Agreement in respect of such settlement or judgment. Furthermore, a Party’s consent to any settlement of a Third-Party Claim shall not be used as evidence of the truth of the allegations in any Third-Party Claim or the merits of such Third-Party Claim and the existence of any Third-Party Claim shall not create a presumption of any breach by a Party to this Agreement of any of its representations, warranties or covenants set forth in this Agreement.

6.4Indemnification Not Involving Third-Party Claims.

(a)In order to seek indemnification under this Section 6.4(a) for a claim which does not involve a Third-Party Claim, the Indemnified Party shall with reasonable promptness deliver a written notice (an “Indemnification Demand”) to the Indemnifying Party which contains (i) a summary, in reasonable detail, of the facts and circumstances giving rise to

such claim and the amount of Damages actually incurred and, to the extent the Damages have not yet been incurred, a good faith, non-binding estimate of the amount of Damages that are reasonably expected to be incurred (to the extent then known), and (ii) a statement that the Indemnified Party is entitled to indemnification under Section 6.1 or Section 6.2 (as the case may be) for such Damages and a reasonable explanation of the basis therefor (to the extent then known).

(b)Upon reasonable request, the Indemnified Party shall furnish the Indemnifying Party with any information to the extent that such information is reasonably necessary in order to evaluate the Indemnification Demand. If the Indemnifying Party in good faith objects to any claim made by the Indemnified Party in the Indemnification Demand, then the Indemnifying Party shall deliver a written notice (an “Indemnification Dispute Notice”) to the Indemnified Party within [*****] days following receipt by the Indemnifying Party of an Indemnification Demand from such Indemnified Party. The Indemnification Dispute Notice shall set forth in reasonable detail the principal basis for the dispute of any claim made by the Indemnified Party in the Indemnification Demand. If the Indemnifying Party fails to deliver an Indemnification Dispute Notice prior to the expiration of such [*****]-day period, then the indemnity claim set forth in the Indemnification Demand shall be conclusively determined in the Indemnified Party’s favor for purposes of this Section 6, and the Indemnified Party shall be indemnified for the amount of the Damages stated in such Indemnification Demand (or, in the case of any notice in which the Damages (or any portion thereof) are estimated, the amount of such Damages (or such portion thereof) as finally determined) on demand or, in the case of any notice in which the Damages (or any portion thereof) are estimated, on such later date when the amount of such Damages (or such portion thereof) becomes finally determined, in either case, subject to the limitations of this Section 6.

(c)If the Indemnifying Party timely delivers an Indemnification Dispute Notice, then the Indemnified Party and the Indemnifying Party shall attempt in good faith to resolve any such objections raised by the Indemnifying Party in such Indemnification Dispute Notice. If the Indemnified Party and the Indemnifying Party agree to a resolution of such objection, then a memorandum setting forth such resolution shall be prepared and signed by both Parties, and shall be binding and conclusive upon the Parties hereto.

(d)If no such resolution can be reached during the [*****]-day period following the Indemnified Party’s receipt of a given Indemnification Dispute Notice, then upon the expiration of such 45-day period (or such longer period as may be mutually agreed by the Parties in writing), the Indemnified Party shall be entitled to pursue all remedies available to it under this Agreement or otherwise at law or in equity with respect to such claims (in each case subject to the terms and limitations set forth in this Agreement).

6.5Limitations. Other than Seller’s indemnification obligations arising out of any Fraud by Seller, in no event shall Seller’s aggregate liability to the Purchaser Indemnified Parties for indemnification claims pursuant to this Section 6 exceed an amount equal to the portion of the (i) Purchase Price, (ii) Milestone Payments, and (iii) Royalty Payments actually received by Seller. The Parties acknowledge and agree that there shall not be any duplicative recovery for any Damages arising from the same facts and circumstances. Except for any Fraud with respect to this Agreement on the part of Seller, the indemnification provided hereunder shall be the sole and exclusive remedy with respect to Damages of any Purchaser Indemnitee. For purposes of this Section, the Shares received as part of any Milestone Payments shall be valued at the [*****].

(a)The representations and warranties made by each of Seller and Purchaser in this Agreement shall survive the Closing and remain in full force and effect until the [*****]-year anniversary of the Closing Date (the “Expiration Date”); provided, however, that the Seller Fundamental Representations shall survive the Closing in accordance with their terms until the [*****] anniversary; provided, further, that for each claim hereunder regarding a representation, warranty, or covenant with respect to which a Claim Notice or an Indemnification Demand is given before the Expiration Date, such claim and associated representation and warranty and right to indemnification (including any right to pursue such indemnification hereunder) will not terminate, and shall survive until (but only for purposes of) the resolution and final determination of such claim covered by such Claim Notice or Indemnification Demand.

(b)Each covenant and agreement in this Agreement that by its nature is required to be performed in full before or after the Closing, and all associated rights to indemnification (including any right to pursue such indemnification hereunder), will survive the Closing and will continue in full force thereafter until the date is [*****] days past the expiration of the applicable statute of limitations period relating to such covenant or agreement. Any claims based on Fraud will survive the Closing indefinitely.

7.1Confidential Information. Except as expressly provided herein, the Parties agree that the receiving Party of Confidential Information shall not, directly or indirectly, publish or otherwise disclose and shall not use for any purpose at any time any Confidential Information (whether or not such information is or was developed by any of them), except to the extent that such disclosure or use is directly related to and required by the performance of duties by the receiving Party to the other Party, or as required by applicable Law or as otherwise provided under Section 7.2. The Parties further agree to take commercially reasonable steps, to the extent within its control, to safeguard such Confidential Information and to protect it against disclosure, misuse, espionage, loss and theft. The Parties agree that Confidential Information is not deemed to be in the public domain merely because any part of the information is embodied in general disclosures or because individual features, components or combinations are now, or become, known to the public. Notwithstanding the foregoing, Confidential Information shall not include information that, in each case as demonstrated by written documentation:

(a)was already known to the receiving Party at the time of disclosure, other than breach of an obligation of confidentiality; provided that, to the extent that Seller is the receiving Party of Confidential Information after the Closing, this exception shall not apply to such Confidential Information known by Seller prior to the Closing;

(b)was generally available to the public or otherwise part of the public domain at the time of its disclosure to the receiving Party;

(c)became generally available to the public or otherwise part of the public domain after its disclosure and other than through any act or omission of the receiving Party in breach of this Agreement; or

8.12Specific Performance; Non-Exclusive Remedies. Each Party agrees that this Agreement is intended to be legally binding and specifically enforceable pursuant to its terms and that Purchaser and Seller would be irreparably harmed if any of the provisions of this Agreement were not performed in accordance with their specific terms and that monetary damages would not provide adequate remedy in such event. Accordingly, except as otherwise specified in this Agreement, in addition to any other remedy to which a non-breaching Party may be entitled at law, a non-breaching Party shall be entitled to seek injunctive relief to prevent breaches of this Agreement and to specifically enforce the terms and provisions hereof, in each case without posting a bond or undertaking, this being in addition to any other remedy to which they are entitled at law or in equity. Each of the Parties agrees that it will not oppose the granting of an injunction, specific performance and other equitable relief when expressly available pursuant to the terms of this Agreement on the basis that the other Party has an adequate remedy at law or an award of specific performance is not an appropriate remedy for any reason at law or equity.

Except as expressly set forth in the Transaction documents to the contrary, each Party shall pay the fees and expenses of its advisers, counsel, accountants and other experts, if any, and all other expenses incurred by such Party incident to the negotiation, preparation, execution, delivery and performance of this Agreement.

(e)compulsory payments and cash rebates related to the sales of Products actually made and given to a governmental authority pursuant to government regulations by reason of any national or local health insurance program or similar program; and

(f)distributors’ and inventory management fees in connection with the sale and distribution of Product to the extent allocable to Product.

(g)amounts written off for uncollectible debt; provided that, the Selling Party shall use commercially reasonable efforts to collect such debt; and provided that if such debts are subsequently collected they shall be included in Net Sales when collected.

For clarity, only items in (a)-(g) above that are deducted from the Permitted Selling Party’s gross invoiced amount for sales of Product in accordance with GAAP, applied on a consistent basis, will be deducted from such gross invoiced amount for purposes of the calculation of Net Sales. For purposes of determining Net Sales, a Product shall be deemed sold as of the date invoiced and a “sale” shall not include transfers or dispositions of Product for pre-clinical, clinical, research or testing purposes, under named patient use, compassionate use, patient assistance, or test marketing programs, in each case at or under COGS. Sales of Products between Permitted Selling Parties for resale shall be excluded from the computation of Net Sales, but the subsequent resale of Products by such Permitted Selling Parties to a Third Party (other than another Permitted Selling Party) shall be included in Net Sales. In the event of any sale or other disposition of a Product for any consideration other than exclusively monetary consideration on bona fide arm’s-length terms, then for purposes of calculating Net Sales under this Agreement, such Product shall be deemed to be sold at the average invoice price of such Product in bona fide arm’s-length transactions (as determined based on the invoiced prices of such Product when sold alone in a transaction, and not with other products) during the applicable reporting period in the country in which such sale or other disposition occurred.

In the event that a Product is sold in any country in the form of a Combination Product, Net Sales of such Combination Product shall be adjusted by multiplying actual Net Sales of such

Combination Product in such country calculated pursuant to the foregoing definition of “Net Sales” by the fraction A/(A+B), where A is the average invoice price in such country of any Product that contains the same Compound(s) as such Combination Product as its sole active ingredient, if sold separately in such country and B is the average invoice price in such country of each product that contains active ingredient(s) other than the Compound(s) contained in such Combination Product as its sole active ingredient(s), if sold separately in such country; provided that the invoice price in a country for each Product that contains only the Compound(s) and the invoice price for each product that contains solely active ingredient(s) other than the Compound(s) included in the Combination Product shall be for a quantity comparable to that used in such Combination Product and of substantially the same class, purity and potency. If either the Product that contains the Compound(s) as its sole active ingredient or a product that contains an active ingredient (other than the Compound(s)) in the Combination Product as its sole active ingredient(s) is not sold separately in a particular country, the Parties shall negotiate in good faith the Net Sales in such country.

WHEREAS, in connection with the ASCA, the Company also desires to engage Consultant, and Consultant desires to provide research and development services to the Company pursuant to the terms and conditions contained herein.

NOW, THEREFORE, in consideration of the premises and mutual promises, covenants and obligations contained herein, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Parties hereby agree as follows:

1.    R&D Services; Staff; Compensation.

(a)    Consulting Services. During the Term, Consultant will provide the Company with research and development services, which will include, among other things, (i) the research and development of the Existing Products (as defined in the ASCA) and the Future Products (as defined in the ASCA) (collectively, the “Products”), including, but not limited to, nonclinical and clinical development, manufacturing, and commercialization of the Products and the performance of other regulatory, clinical operations, pharmacovigilance, medical monitoring and planning (together, the “Services”). The Services to be performed by Consultant shall be described in the Non-Clinical and Clinical Development SOW (as defined in the ASCA) attached hereto as Exhibit A. All Services will be performed and completed in a competent fashion in accordance with applicable industry and Company’s standards, and all Services are subject to final approval by a Representative (as defined below) of Company prior to payment.

(b)    Staff. Unless otherwise agreed by the Parties, Consultant agrees that the Services will solely be performed by [*****]. Consultant will not have any authority to obligate the Company in any way absent specific direction and approval to do so from the Company or any of its authorized Representatives (as defined below).

(c)    Compensation. In exchange for the Services, the Company will pay Consultant the fees, other compensation and certain related expenses also described in Exhibit A (Non-Clinical and Clinical Development SOW). Upon the termination of this R&D Services Agreement in accordance with Section 6 (Termination of R&D Services Agreement; Survival), the Company shall have no obligation to pay fees, commissions, or any other amounts under this R&D Services Agreement for Services or expenses with respect to any period on or after the date of such termination.

2.    Term. Unless earlier terminated as provided for in Section 6 (Termination of R&D Services Agreement; Survival), this R&D Services Agreement is effective as of the Effective Date until the completion of the Services (the “Term”).

3.     Confidentiality; Proprietary Agreement.

(a)    Confidentiality Agreement. Section 7 (Confidentiality) of the ASCA remains in full force and effect and all information and materials disclosed by the Company prior to, or as of, the Effective Date under Section 7 (Confidentiality) of the ASCA and/or during the Term, to the extent meeting the requirements of the definition of Confidential Information thereunder, shall be protected as Confidential Information under this R&D Services Agreement.

(b)    Inventions Assignment Agreement. Prior to any effectiveness of this R&D Services Agreement, Consultant shall execute and deliver to the Company a copy of the Inventions Assignment and Non-Compete Agreement (the “Inventions Assignment Agreement”) in the form attached hereto as Exhibit B.

4.    Conflicting Obligations.

(a)    Conflicts. Consultant certifies that neither it nor any of its directors, officers, employees, consultants, advisors, agents, or representatives (“Representatives”) has any outstanding agreement or obligation that is in conflict with any of the provisions of this R&D Services Agreement or that would preclude it or any of its Representatives from complying with the provisions of this R&D Services Agreement or any agreements provided for herein. Consultant agrees that neither it nor any of its Representatives will enter into any such conflicting agreement during the Term. Consultant’s or any of its Representatives’ violation of this Section 4(a) will be considered a material breach under Section 6(b)(ii).

(b)    Substantially Similar Products. In view of Consultant’s access to the Company’s trade secrets and proprietary know-how, Consultant will not, without the Company’s prior written approval, design, or assist others in the design of, identical or substantially similar Products (as defined in the ASCA), Compounds (as defined in the ASCA), and/or drug candidates ([*****]) as those developed under this R&D Services Agreement for any third party during the Term and after the termination of this R&D Services Agreement. Consultant acknowledges that the obligations in this Section 4(b) are ancillary to its obligations under Exhibit B (Inventions Assignment Agreement).

(c)    Separation. The Company acknowledges that Consultant may be engaged in consulting services with other entities and that the Consultant may be subject to certain confidentiality agreements with other entities. Consultant shall be solely responsible for ensuring its compliance with those agreements and any other limitations that may be imposed on Consultant. Consultant shall use its best efforts to minimize or avoid any questions of disclosure of, or rights under, any inventions made by Consultant in providing the Services to the Company (and to assist the Company and Consultant’s other clients in fairly resolving any questions which may arise). All Services and related documentation in connection with this R&D Services Agreement shall be kept completely separate from Consultant’s other consulting activities and its employees and consultants (other than any employee or consultant who will assist Consultant in providing the Services under this agreement) in order to avoid any preemptions or overlap of other rights or obligations of the Consultant.

5.    Reports. Consultant will, from time to time during the Term, keep the Company advised as to the Services under this R&D Services Agreement. In addition, Consultant will, as requested by the Company, prepare written reports with respect to such progress. The time

required to prepare such written reports will be considered time devoted to the performance of the Services.

(a)    Termination by Company. Company shall have the right to terminate this R&D Services Agreement (or the Non-Clinical and Clinical Development Plan) in the event of any of the following:

(i)    For convenience upon a sixty (60) days’ prior written notice to Consultant; or

(ii)    The Product or Products are determined by Company or a regulatory authority to have material safety risks or sufficient questions regarding efficacy or substantial manufacturing concerns, in each case leading to the cessation or termination of development, manufacture or commercialization of, or seeking regulatory approval for, the Products.

(b)    Mutual Termination. Either Party hereto shall have the right to terminate this R&D Services Agreement by giving the other Party written notice in the event of any of the following:

(i)    The bankruptcy or insolvency of the other Party; or

(ii)    If the other Party is in material breach of this R&D Services Agreement, provided that if the breach is capable of cure (1) the non-breaching Party shall first provide [*****] days’ prior written notice and an opportunity to cure to the breaching Party, and (2) in the event the breach is not cured within such [*****]-day period, the breaching Party has not diligently pursued an acceptable cure and provided a reasonable plan of proposed actions and schedule for completing such cure outside the [*****]-day period that the non-breaching Party agrees, in its sole discretion, is reasonably likely to allow for cure in a sufficient and timely enough manner; or

(iii)    The other Party is suspended or debarred by FDA or the United States government.

(c)    Survival. Upon termination or expiration of this R&D Services Agreement, all rights and duties of the Company and Consultant toward each other shall cease; provided that the following shall survive the termination or expiration of this R&D Services Agreement:

(i)    The Company will pay, within [*****] days after the effective date of such termination, all amounts owing to Consultant for Services completed and accepted by the Company prior to the termination date and related expenses, if any, submitted in accordance with the Company’s policies and in accordance with the provisions of Exhibit A (Non-Clinical and Clinical Development SOW);

(ii)    Consultant will promptly deliver to the Company any and all documents, records, data, notes, reports, proposals, lists, correspondence, specifications, drawings, blueprints, sketches, materials, devices, equipment, other property, or reproductions of any aforementioned items developed by Consultant pursuant to this Consultant Agreement or otherwise belonging to the Company, its successors or assigns; provided that Consultant shall be entitled to keep one (1) archival copy of such materials for purposes of demonstrating compliance with

the terms of this R&D Services Agreement and provided further that Consultant’s obligation to return such materials does not apply to such materials stored in routine system backups, provided further that (1) such backups are not readily accessible to users, and (2) any such retained information will be subject to the confidentiality obligations of this R&D Services Agreement for so long as such Confidential Information is retained and will be destroyed by Consultant in the ordinary course per its usual business practices or policies; and

(iii)    Section 3 (Confidentiality Agreement; Inventions Assignment Agreement), Section 4 (Conflicting Obligations), Section 6(c) (Survival), Section 7 (Independent Contractor; No Benefits), Section 8 (Miscellaneous), and Exhibit B (Inventions Assignment Agreement) will survive termination of this R&D Services Agreement.

7.     Independent Contractor; No Benefits

(a)    Independent Contractor. It is the express intention of the Company and Consultant that Consultant provides the Services as an independent contractor to the Company. Nothing in this R&D Services Agreement shall in any way be construed to deem Consultant and/or any of its Representatives as an agent, employee or representative of the Company during the Term. Without limiting the generality of the foregoing, during the Term, neither Consultant nor any of its Representatives are authorized to bind the Company to any liability or obligation or to represent that it has any such authority, except where expressly delegated in writing by the Company’s authorized Representatives. Consultant is obligated to report as income all fees and other compensation received pursuant to under this R&D Services Agreement in compliance with applicable laws. Further, to the extent applicable, Consultant acknowledges its obligation to pay all, as the case may be, self-employment and other taxes on such income.

(b)    No Benefits. During the Term, neither Consultant nor any of its Representatives will receive Company-sponsored benefits that the Company may make available to its employees, including, but not limited to, group health or life insurance, profit-sharing or retirement benefits. If Consultant or any of its Representatives were to be reclassified by a state or federal agency or court as Company’s employee under applicable law or otherwise with respect to the provision of Services hereunder, neither Consultant nor any of its Representatives will be eligible to receive any employee benefits from the Company, except those mandated by state or federal law, even if by the terms of the Company’s benefit plans or programs in effect at the time of such reclassification, Consultant or any of its Representatives would otherwise be eligible for such benefits.

(c)    Taxes; Workers’ Compensation and Other Benefits. The Company will not withhold any taxes from payments made to Consultant related to the Services and will only report its gross fees or other compensation related to the Services to the extent required by law. To the extent applicable, Consultant is also solely responsible for the payment of all federal, state, local, or other applicable taxes, income or otherwise, incurred or due as a result of the receipt of gross fees or other compensation for the Services hereunder, and Consultant will file, on a timely basis, all tax returns required to be filed by any federal, state, or local tax authority with respect to the receipt of gross fees or other compensation for the Services hereunder. Consultant shall make such payments referred to in this paragraph as required by law.

(a)    Applicable Law; Mediation and Arbitration. Section 8.7 (Applicable Law; Mediation and Arbitration) of the ASCA is hereby incorporated by reference as if fully stated herein.

(b)    Assignability. Consultant shall not sell, assign or delegate any rights or obligations under this R&D Services Agreement without the previous written consent of the Company. This Agreement may be assigned by the Company to any Affiliate or, in connection with a merger, consolidation, or sale of all or substantially all of the assets to which this R&D Services Agreement relates. Any assignment not in compliance with this R&D Services Agreement will be null, void and of no effect. This R&D Services Agreement will be binding upon and inure to the benefit of each Party’s permitted assigns and successors-in-interest. No assignment will relieve either Party of the performance of any accrued obligation that such Party may then have under this R&D Services Agreement.

(d)    Entire Agreement. This R&D Services Agreement and the Exhibits constitute the entire agreement between the Parties with respect to the subject matter of this R&D Services Agreement and supersedes all prior written and oral agreements between the Parties regarding the subject matter of this R&D Services Agreement.

(e)    Headings. Headings are used in this R&D Services Agreement for reference only and shall not be considered when interpreting this R&D Services Agreement.

(f)    Notices. Any notice or other communication required or permitted to be delivered to any Party under this R&D Services Agreement shall be in writing and shall be deemed properly delivered, given and received (a) upon receipt when delivered by hand, or (b) one business day after being sent by courier or express next-day delivery service, provided that in each case the notice or other communication is sent to the address set forth beneath the name of such Party below (or to such other address or e-mail address as such Party shall have specified in a written notice given to the other Party):

(g)    Severability. If any term or other provision of this R&D Services Agreement, or any portion thereof, is invalid, illegal or incapable of being enforced by any rule of law or public policy, all other terms and provisions of this R&D Services Agreement, or remaining portion thereof, shall nevertheless remain in full force and effect. Upon such determination that any such term or other provision, or any portion thereof, is invalid, illegal or incapable of being enforced, the Parties shall negotiate in good faith to modify this R&D Services Agreement so as to effect the original intent of the Parties as closely as possible in an acceptable manner to the end that the Services are performed to the fullest extent possible.

(h)    Incorporation of Exhibits. The exhibits attached hereto and referred to herein are hereby incorporated by reference herein and made part of this R&D Services Agreement for all purposes as if fully set forth herein. In the event of a conflict between the terms contained in any Exhibit and this R&D Services Agreement, the terms of this R&D Services Agreement shall control, unless specifically agreed upon to the contrary in the relevant Exhibit.

(i)    Counterparts; Electronic Copies of Signatures and Original Agreement. This R&D Services Agreement may be executed in two (2) or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. Each Party may execute this Agreement by facsimile transmission or in Adobe™ Portable Document Format (PDF) sent by electronic mail.

Section 1.1    Assignment of Inventions. Consultant agrees that it and its Affiliates (as defined in the ASCA) and their stockholders, members, managers, directors, officers, employees, consultants, advisors or other agents (the “Representatives”) will promptly make full written disclosure to the Company, will hold in trust for the sole right and benefit of the Company, and hereby assign to the Company, or its designee, all of its right, title, and interest in and to any and all inventions, original works of authorship, writings, developments, concepts, improvements, designs, discoveries, ideas, processes, formulas, data, trademarks or trade secrets, whether or not patentable or registrable under copyright or similar laws, made or conceived or reduced to practice or learned by Consultant’s Representatives, either alone or jointly with others, during the Term (as defined in the R&D Services Agreement), which are (a) within the scope of the Services and/or the Non-Clinical and Clinical Development SOW to be performed by Consultant under the R&D Services Agreement and related to or useful in the business of the Company, or (b) a direct result from tasks assigned to Consultant or its Representatives by the Company, or (c) funded by the Company, (collectively, “Inventions”). Consultant agrees that the Company will exclusively own all work product that is made by Consultant or its Representatives (solely or jointly with others) within the scope of Consultant’s engagement. Consultant further acknowledges that all original works of authorship which are made by Consultant or its Representatives (solely or jointly with others) within the scope of the R&D Services Agreement and/or the Non-Clinical and Clinical Development SOW and during the Term and which are protectable by copyright are “works made for hire,” as that term is defined in the United States Copyright Act. Consultant acknowledges and agrees that nothing in this Inventions Assignment Agreement shall be deemed to grant, by implication, estoppel or otherwise, a license from the Company to Consultant or its Representatives to make, use, license, or transfer in any way an existing or future Invention (including Future Products (as defined in the R&D Services Agreement)).

Section 1.2    Maintenance of Records. Consultant agrees to keep and maintain adequate and current written records of all Inventions made by Consultant or its Representatives (solely or jointly with others) during the Term. The records will be in the form of notes, sketches, drawings, and any other format that may be specified by the Company. The records will be available to and remain the sole property of the Company at all times.

Section 1.3    Patent and Copyright Registrations. Consultant agrees to reasonably assist, and cause its Representatives to reasonably assist, the Company, or its designee, at the Company’s expense, in every proper way to secure the Company’s rights in the Inventions and any copyrights, patents, mask work rights or other intellectual property rights relating thereto in

any and all countries, including the disclosure to the Company of all pertinent information and data with respect thereto, the execution of all applications, specifications, oaths, assignments and all other instruments which the Company shall deem necessary in order to apply for and obtain such rights and in order to assign and convey to the Company, its successors, assigns, and nominees the sole and exclusive rights, title, and interest in and to such Inventions, and any copyrights, patents, mask work rights or other intellectual property rights relating thereto. Consultant further agrees that Consultant’s obligation to execute or cause to be executed, when it is in Consultant’s power to do so, any such instrument or papers shall continue after the termination of the R&D Services Agreement.

    Section 2.1    Subject to the Closing (as defined in the ASCA), and as an inducement to the Company to execute the ASCA and complete the Transactions (as defined in the ASCA), and in order to preserve the goodwill associated with the Purchased Assets (ASCA), the Consultant hereby covenants and agrees that for a period of [*****] years from and after the Closing Date (as defined in the ASCA), it will not, and will cause its respective Representatives not to, directly or indirectly, operate or consult for a Competing Business in the United States of America, Europe, and Japan. The Company and Consultant agree that for purposes of this Inventions Assignment Agreement, “Competing Business” means any product, service, or process or the research and development thereof, of any Person (as defined in the ASCA) other than the Company that is substantially similar to, or competitive with a product, service, or process (including the Products (as defined in the ASCA)), including the research and development thereof, of the Company with which Consultant and its Representatives worked directly or indirectly during its engagement by the Company or about which Consultant acquired Confidential Information (as defined in the ASCA) during its engagement by the Company.

Section 2.2    The Company and Consultant intend that this covenant not to compete shall be construed as separate covenants, one for each state, county and subdivision to which the covenant applies. In the event a court of competent jurisdiction determines that the provisions of this covenant not to compete are excessively broad as to duration, geographic scope or activity, it is expressly agreed that this covenant not to compete shall be construed so that the remaining provisions shall not be affected, but shall remain in full force and effect, and any such over broad provisions shall be deemed, without further action on the part of any Person (as defined in the ASCA), to be modified, amended or limited, but only to the extent necessary to render the same valid and enforceable in such jurisdiction.

DeuteRx also understands that the Shares are being offered and sold pursuant to an exemption from registration contained in the Securities Act based in part upon DeuteRx’s representations contained in this Agreement. DeuteRx hereby represents and warrants as follows:

(a)    DeuteRx Bears Economic Risk. DeuteRx has substantial experience in evaluating and investing in private placement transactions of securities of companies in a similar stage of development as the Company so that DeuteRx is capable of evaluating the merits and risks of DeuteRx’s investment in the Company and has the capacity to protect DeuteRx’s own interests. DeuteRx can bear the economic risk of this investment indefinitely. DeuteRx understands that the Company has no present intention of registering the Shares. DeuteRx also understands that there is no assurance that any exemption from registration under the Securities Act will be available and that, even if available, such exemption may not allow DeuteRx to transfer all or any portion of the Shares under the circumstances, in the amounts or at the times DeuteRx might propose.

(b)    Acquisition for Own Account. DeuteRx is acquiring the Shares for DeuteRx’s own account for investment only, not as a nominee or agent and not with a view towards their resale or distribution. DeuteRx has no present intent of selling, granting any participation in, or otherwise distributing the Shares. By executing this Agreement, DeuteRx further represents that DeuteRx does not presently have any contract, undertaking, agreement or arrangement with any person to sell, transfer or grant participations to such person or to any third person, with respect to any of the Shares. DeuteRx has not been formed for the specific purpose of acquiring the Shares.

(c)    DeuteRx Can Protect DeuteRx’s Interest. DeuteRx represents that by reason of DeuteRx’s, or of DeuteRx’s management’s, business or financial experience, DeuteRx has the capacity to protect DeuteRx’s own interests in connection with the transactions contemplated in this Agreement.

DeuteRx has also had the opportunity to ask questions of, receive answers from and obtain additional information from (to the extent the Company possessed such information or could acquire it without unreasonable effort or expense) the Company and its management regarding the terms and conditions of this investment.

(f)    Rule 144. DeuteRx understands that the Shares have not been, and will not be, registered under the Securities Act, by reason of a specific exemption from the registration provisions of the Securities Act, which depends upon, among other things, the bona fide nature of the investment intent and the accuracy of DeuteRx’s representations as expressed herein. DeuteRx acknowledges and agrees that the Shares are “restricted securities” as defined in Rule 144 promulgated under the Securities Act as in effect from time to time and must be held indefinitely unless they are subsequently registered under the Securities Act or an exemption from such registration is available. DeuteRx has been advised or is aware of the provisions of Rule 144, which permits limited resale of shares purchased in a private placement subject to the satisfaction of certain conditions, including, among other things: the availability of certain current public information about the Company, the resale occurring following the required holding period under Rule 144 and the number of shares being sold during any three-month period not exceeding specified limitations.

(g)    Residence. The office of DeuteRx in which DeuteRx’s decision to purchase the Shares was made is located at the address of DeuteRx set forth on Section 7.8. DeuteRx’s tax identification number is set forth on the signature page hereto.

4.5    No Governmental Review. DeuteRx understands that no United States federal or state agency or any other government or governmental agency has passed on or made any recommendation or endorsement of the Shares or the fairness or suitability of the investment in the Shares nor have such authorities passed upon or endorsed the merits of the offering of the Shares.

4.6    Transfer Restrictions. DeuteRx acknowledges and agrees that the Shares are subject to restrictions on transfer as set forth in this Agreement. DeuteRx understands that the Shares and any securities issued in respect of or exchange for the Shares, may bear one or all of the following legends:
