[***]

5.13.

Taxes.

5.13.1.

General. It is understood and agreed between the Parties that any payments made under this Agreement are exclusive of any value added or similar tax (“VAT”), which shall be added thereon as applicable. In the event any payments made by Pyxis to Pfizer pursuant to this Agreement become subject to withholding taxes under the laws or regulation of any jurisdiction, Pyxis shall deduct and withhold the amount of such taxes for the account of Pfizer to the extent required by Applicable Law and such amounts payable to Pfizer shall be reduced by the amount of taxes deducted and withheld, which shall be treated as paid to Pfizer in accordance with this Agreement. To the extent that Pyxis is required to deduct and withhold taxes on any payments under this Agreement, Pyxis shall pay the amounts of such taxes to the proper Governmental Authority in a timely manner and promptly transmit to the payee an official tax certificate or other evidence of such withholding sufficient to enable Pfizer to claim such payments of taxes. Pfizer shall provide any tax forms to Pyxis that may be reasonably necessary in order for Pyxis not to withhold tax or to withhold tax at a reduced rate under an applicable bilateral income tax treaty.

Tax Actions. Notwithstanding anything in this Agreement to the contrary, if an action, including but not limited to any assignment or sublicense of its rights or

obligations under this Agreement, or any failure to comply with Applicable Laws or filing or record retention requirements (a “Tax Action”) by a Party leads to the imposition of withholding tax liability or VAT on the other Party that would not have been imposed in the absence of a Tax Action or in an increase in such liability above the liability that would have been imposed in the absence of such Tax Action, then (i) the sum payable by the Party that caused the Tax Action (in respect of which such deduction or withholding is required to be made) shall be increased to the extent necessary to ensure that the other Party receives a sum equal to the sum which it would have received had no Tax Action occurred and (ii) the sum payable by the Party that caused a Tax Action (in respect of which such deduction or withholding is required to be made) shall be made to the other Party after deduction of the amount required to be so deducted or withheld, which deducted or withheld amount shall be remitted in accordance with Applicable Law. For the avoidance of doubt, a Party shall only be liable for increased payments pursuant to this Section 5.13.2 to the extent such Party engaged in a Tax Action that created or increased a withholding tax or VAT on the other Party.

5.13.3.

Cooperation. The Parties agree to cooperate and produce on a timely basis any tax forms or reports, including an IRS Form W-8BEN, reasonably requested by the other Party in connection with any payment made by Pyxis to Pfizer under this Agreement.

6.4.

Payment of Deficiency. If any audit establishes that Pyxis underpaid any amounts due to Pfizer under this Agreement, then Pyxis shall pay Pfizer any such deficiency within [***]

after receipt of written notice thereof. For the avoidance of doubt, such payment will be considered a late payment, subject to Section 5.10.

Intellectual Property Rights.

7.1.

Pre-existing IP. Subject only to the rights expressly granted to the other Party under this Agreement, each Party shall retain all rights, title and interests in and to any Intellectual Property Rights that are owned, licensed or sublicensed by such Party prior to or independent of this Agreement.

Upon receipt of such communications, Pyxis shall have [***] to provide Pfizer with any comments with regard to such communications. [***]. If Pfizer decides to abandon any Licensed Platform Patent Rights [***], Pfizer shall inform Xxxxx in writing, Xxxxx will have [***] to notify Pfizer in writing if Xxxxx wishes to take over the filing, prosecution and maintenance of such Licensed Platform Patent Rights, and Xxxxx will be responsible for the same at Pyxis’s own cost and expenses immediately upon such written notice.

7.2.2.

Assistance.

or maintenance of such Patent Right in Pfizer’s name using counsel of its own choice and at its own expense, in which case, as of the date Pyxis provides Pfizer such Election Notice, the applicable license granted in Section 2.2.1 with respect to such patent rights shall become non-exclusive and non-sublicensable (to the extent Pyxis has not sublicensed such Patent Right prior to providing such Election Notice), and Pyxis will have no further rights in respect of the filing, maintenance or enforcement of such Patent Right.

Right of First Enforcement.

(a)

Pyxis shall have the first right (but not the obligation), at its own expense, to control enforcement of the Licensed ADC Patent Rights against any Third Party Infringement within the scope of its exclusive license and may name Pfizer as a party for standing purposes. Prior to commencing any such action, Pyxis shall consult with Pfizer and shall give due consideration to Pfizer’s recommendations regarding the proposed action. Pyxis shall give Pfizer timely notice of any proposed settlement of any such action instituted by Xxxxx and shall not, without the prior written consent of Pfizer, enter into any settlement that would: (i) adversely affect the validity, enforceability or scope of any of the Licensed ADC Patent Rights, (ii) give rise to liability of Pfizer or its Affiliates, (iii) admit non-infringement of any Licensed ADC Patent Rights, or (iv) otherwise impair Pfizer’s rights in any Licensed ADC Technology, Licensed Platform Technology or this Agreement.
