If the Net Sales Milestone is achieved before the [***] Milestone, then the [***] Milestone will be deemed to have occurred upon the occurrence of the Net Sales Milestone. Any amount paid to Seller pursuant to Section 1.5(b)(i)(A) or Section 1.5(b)(i)(B) shall be treated as an adjustment to the purchase price for Tax purposes and shall be treated as such by Buyer and Seller on their respective Tax Returns, unless otherwise required by applicable Law.

(iii)As used herein, “Net Sales” means [***].

Section 1.6Interest

If any amount payable under this Agreement is not paid in full by the date on which such amount is required to be paid pursuant to the terms hereof, then the Party entitled to receive such payment may charge interest on any outstanding amount of such payment, accruing as of the original due date, at an annual rate equal to the lesser of (a) the sum of (i) the U.S. prime rate (as reported in The Wall Street Journal as may vary during the applicable interest rate period; provided that, in event that The Wall Street Journal reports more than one such rate, or a range of rates, at any time, then the mean of the quoted rates; provided further that, in the event that The Wall Street Journal fails to report any such rate, then the mean annual interest rate of the four largest U.S. money center commercial banks) plus (ii) two percentage points (2.0%) and (b) the maximum rate allowable by applicable Law. The accrual or payment of such interest shall not foreclose a Party

from exercising any other rights to which such Party may be entitled as a result of the delay in or failure to make payment by the other Party.

Section 1.7Withholding of Taxes.

Each Party (and its respective Affiliates and agents) shall be entitled to deduct and withhold from amounts payable pursuant to this Agreement such amounts that are required to be deducted and withheld under applicable Law; provided, however, that if applicable Laws require a Party to deduct and withhold Taxes from any amounts payable or otherwise deliverable pursuant to this Agreement, then such amounts shall be remitted to the proper federal, state, local or foreign Tax authorities and such amount shall not reduce the amount due to the recipient Party hereunder; provided further that the foregoing proviso shall not apply to the extent that any Party that is a recipient of a payment hereunder takes any action after the date hereof that results in an increase in withholding Taxes that would not be required absent such action, including a change of control, change in tax residence (including through redomestication, permanent establishment or branch), or sublicense or assignment of any rights under this Agreement. Both Parties will cooperate in taking necessary measures, including timely preparation of necessary documents, so that the payments made under this Agreement will be exempt from withholding tax.

Section 1.8Allocation.

Buyer and Seller shall reasonably cooperate with one another with respect to all matters related to any allocation of the Purchase Price (as well as any other items properly treated as consideration for Tax purposes) among the Purchased Assets that is undertaken for the Tax reporting purposes in the respective jurisdictions of Buyer and Seller. Nothing in this provision shall be construed to require the Parties to agree on a single allocation of the Purchase Price and each Party may freely assign its own allocation of the Purchase Price among the Purchased Assets for its respective Tax purposes.

Section 1.9Closing.

If any Party has breached any representation, warranty, or covenant contained herein (or is otherwise entitled to indemnification) in any respect, the fact that there exists another representation, warranty, or covenant (including any indemnification provision) relating to the same subject matter (regardless of the relative levels of specificity) which such Party has not breached (or is not otherwise entitled to indemnification with respect thereto) shall not detract from or mitigate the fact that such Party is in breach of the first representation, warranty, or covenant (or is otherwise entitled to indemnification pursuant to a different provision).

(f)The Schedules and Exhibits to this Agreement are a material part hereof and shall be treated as if fully incorporated into the body of this Agreement.

Section 7.13Severability.

Whenever possible, each provision or portion of any provision of this Agreement shall be interpreted in such manner as to be effective and valid under applicable Law, but if any provision or portion of any provision of this Agreement is held to be invalid, illegal or unenforceable in any respect under any applicable Law, such invalidity, illegality or unenforceability shall not affect the validity, legality or enforceability of (a) any other provision or portion of any provision in such jurisdiction or (b) any provision of this Agreement in any other jurisdiction.

Section 7.14Specific Performance.

The Parties agree that irreparable damage, for which monetary damages (even if available) would not be an adequate remedy, would occur in the event any provision hereof were not performed in accordance with the terms hereof and that the Parties will be entitled to seek specific performance of the terms hereof, in addition to any other remedy at law or in equity, through arbitration in accordance with Section 7.4(b) (or on an interim or temporary basis pending final resolution by arbitration in accordance with Section 7.4(b), any court in any jurisdiction, whether within or outside of the United States), without the necessity of demonstrating the inadequacy of monetary damages and without the posting of a bond. Each Party agrees that it will not oppose any request of specific performance or other equitable relief on the basis that the other Party has an adequate remedy at law or that an award of specific performance is not an appropriate remedy for any reason at law or equity.

Section 7.15Force Majeure.

Neither Seller nor any of its Affiliates shall be held liable to Buyer, nor be deemed to have defaulted under or breached this Agreement, for failure or delay in performing any obligation under Section 5.3(b) to the extent such failure or delay is caused by or results from causes beyond the reasonable control of Seller and its Affiliates, including embargoes, war, acts of war (whether war be declared or not), insurrections, riots, civil commotions, strikes, lockouts or other labor disturbances, fire, floods, epidemic, pandemic or other acts of God or any other deity, or acts, omissions or delays in acting by any Governmental Authority. In such event, (a) Seller shall notify Buyer of such force majeure circumstances as soon as reasonably practical, and shall promptly undertake all reasonable efforts necessary to cure such force majeure circumstances, and (b) excuse from performance under Section 5.3(b) shall be continued so long as the condition constituting force majeure continues and Seller and its Affiliates use reasonable efforts to remove the condition.

Capitalized terms used but not defined herein will have the meanings ascribed to such terms by the Agreement (as defined below).

WHEREAS, Transferor and Transferee are entering into that certain Asset Purchase Agreement, dated as of the date hereof (the “Agreement”), pursuant to which, among other things, Transferor is agreeing to sell, transfer, convey, assign and deliver to Transferee, and Transferee is agreeing to purchase, acquire and accept from Transferor, all of the right, title and interest of Transferor in and to the Purchased Assets;

WHEREAS, as contemplated by the Agreement, Transferor and Transferee desire to document the transfer of the Purchased Assets, other than the Transferred Patents and the Relevant Contracts (the “Transferred Assets”), from Transferor to Transferee on the terms set forth herein.

NOW, THEREFORE, in consideration of the premises and the mutual covenants and the agreements herein set forth, and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto hereby agree as follows:

0.Xxxx of Transferred Assets. In consideration of the mutual obligations, releases and promises set forth in the Agreement, Transferor by this Bill of Sale does hereby transfer, convey, assign and deliver to Transferee all of the right, title and interest of Transferor in and to the Transferred Assets, free and clear of all Liens except Permitted Liens. For the avoidance of doubt, in accordance with the Agreement, (a) in no event shall the Transferred Assets include any Excluded Assets and (b) Transferee assumes no Obligations of Transferor involving the Transferred Assets which arise from any period prior to the Closing Date or any other Excluded Obligations, and any such Obligations shall remain the sole responsibility of Transferor.

The power of attorney referred to in the preceding sentence is and shall be coupled with an interest and shall be irrevocable, and shall survive the dissolution or insolvency of Transferor.

4.Further Assurances. Transferor hereby covenants that, from time to time after the delivery of this Bill of Sale, at Transferee’s request and without further consideration, Transferor will do, execute, acknowledge and deliver, or will cause to be done, executed, acknowledged and delivered, all such further acts, deeds, conveyances, transfers, assignments, powers of attorney and assurances as reasonably may be requested by Transferee to more effectively convey, transfer to and vest in Transferee, and to put Transferee in possession of, any of the Transferred Assets.

5.Entire Agreement; Supremacy.

In the event of any conflict between the terms of the Agreement and the terms hereof, the terms of the Agreement shall govern.

Any purported assignment in contravention of this Section 8 shall be void and invalid.
