3. Intellectual Property Rights.

3.1 Ownership of and License to Antibodies. As between the parties, TeneoBio owns and shall own all Antibodies (including Selected Antibodies) generated or first invented by or on behalf of TeneoBio, and all intellectual property rights therein, and has the exclusive right to prosecute and maintain patent protection thereon. Subject to the terms and conditions of this Agreement, TeneoBio hereby grants to Licensee, effective upon the date Licensee pays the Selected Antibody License Fee (defined below) in full, an exclusive, perpetual, worldwide, royalty-bearing, sublicenseable through multiple tiers, non-transferrable (except in accordance with Section 10.2) license under the TeneoBio Technology (a) to make, have made and use Delivered Antibodies and CAR Cells during the Selection Period for the purpose of determining which Delivered Antibodies to select as Selected Antibodies, (b) to make, have made and use each Selected Antibody for the purpose of researching, developing, making, having made, using, selling, offering for sale, distributing, promoting, importing, or exporting only CAR Cells expressing Selected Antibodies and CAR Products in the Field, and (c) to research, develop, make, have made, use, import and export CAR Cells expressing Selected Antibodies and CAR Products in the Field and to sell, offer for sale, distribute and promote CAR Products in the Field. For clarity, the foregoing license is to the TeneoBio Technology only; to the extent the CAR Cells or CAR Products include or embody any other intellectual property or proprietary rights (the “Non-TeneoBio Rights”), TeneoBio is not granting any license in or to such Non-TeneoBio Rights. During the Term, TeneoBio shall not, itself or with or through an Affiliate or Third Party, and shall not grant a Third Party any rights to, develop, manufacture or commercialize, in the Field, any Delivered Antibody or any product containing or service that uses a Delivered Antibody. For the avoidance of doubt, nothing herein shall restrict TeneoBio from using, licensing, and/or exploiting the Delivered Antibodies freely outside of the Field.

3.2 Ownership, Development and Commercialization of CAR Products. As between the parties, subject to the rights and licenses set forth herein, Licensee owns any CAR Cells derived from or containing any Selected Antibody and any CAR Products. As between the parties, Licensee shall have the sole right and responsibility to research, develop, make, have made, and commercialize the CAR Products, and as between the parties, shall be responsible for all marketing, regulatory and development costs directed towards obtaining Regulatory Approval and selling CAR Products. As between the Parties, Licensee will have the sole right to file, prosecute, maintain, defend and enforce patent applications and patents covering CAR Cells derived from or containing any Selected Antibody and CAR Products.

3.3 Reservation of Rights. Except for the rights specifically and unambiguously granted in this Agreement, no right or license is granted or implied. For the avoidance of doubt, TeneoBio does not grant any rights in UniRat to Licensee. Except as provided in Section 3.1 with respect to Delivered Antibodies and Selected Antibodies, nothing herein shall be construed to limit or restrict, in any manner, TeneoBio’s ability to use and exploit, or allow any Person to use or exploit, UniRat organisms and/or any materials derived or developed therefrom (including antibodies or pharmaceutical products) outside the scope of this Agreement. Without limiting the foregoing and notwithstanding anything to the contrary herein, Licensee understands and agrees that TeneoBio may perform (or may have performed) immunization services for its Affiliates or Third Parties (and/or may allow its Affiliates or Third

TeneoBio – Poseida Therapeutics

Confidential

Parties to perform or may have allowed its Affiliates or Third Parties to perform immunization services) with respect to targets provided or designated by such Affiliates or Third Parties, which may produce (or may have produced) similar antibodies to the Antibodies (including the Selected Antibodies); the foregoing shall not be deemed a breach of this Agreement, including without limitation any warranty made by TeneoBio hereunder, so long as TeneoBio complies with Section 3.1 with respect to the Delivered Antibodies.

3.4 Patent Prosecution.

(a) Subject to Section 3.4(b), TeneoBio shall use commercially reasonable efforts to prepare, file, prosecute and maintain all patents and patent applications, owned by TeneoBio within the TeneoBio Technology that cover the Selected Antibodies (the “TeneoBio Patents”), […***…]; provided, however, that TeneoBio shall (A) provide all information reasonably requested by Licensee with respect to the TeneoBio Patents, (B) promptly notify Licensee in writing with respect to all significant developments regarding the TeneoBio Patents, (C) promptly provide Licensee with a copy of each material communication from any patent authority regarding the TeneoBio Patents, and (D) provide Licensee with drafts of each material filing (including draft patent applications and responses to office actions and similar filings) with respect to the TeneoBio Patents a reasonable amount of time in advance of the anticipated filing date and shall, prior to filing, consider Licensee’s reasonable comments in good faith.

(b) In the event that TeneoBio determines not to file, maintain or continue prosecution of any patent or patent application within the TeneoBio Patents, TeneoBio shall provide Licensee written notice thereof at least […***…] days before the applicable deadline. Upon receipt of such notice, Licensee shall have the right, but not the obligation, at its expense, to assume responsibility for filing, prosecuting, and maintaining such patents and patent applications. If Licensee decides to assume such responsibility, in its sole discretion, it shall so notify TeneoBio in writing. As soon as practicable after receipt of such notice from Licensee, TeneoBio shall, […***…], (i) transfer the existing, complete patent files for all applicable patents and patent applications to Licensee, (ii) file all documents necessary to transfer correspondence with the U.S. Patent and Trademark Office and other applicable patent authorities to Licensee and (iii) give Licensee’s patent counsel power of attorney thereto. TeneoBio shall cooperate with Licensee in the transfer of all prosecution and maintenance responsibilities relating to the TeneoBio Patents, […***…].

(c) Each party shall reasonably cooperate with the other party, […***…], to execute such lawful papers and instruments and to make such rightful oaths and declarations as may be necessary or useful in the preparation and prosecution of the TeneoBio Patents.

(d) Without limiting the foregoing, during the Selection Period, TeneoBio shall use commercially reasonable efforts to prepare, file, prosecute and maintain all patents and patent applications, owned by TeneoBio within the TeneoBio Technology that cover all Delivered Antibodies (provided that, for clarity, those patents not covering the Selected Antibodies are not TeneoBio Patents hereunder).

3.5 Patent Enforcement.

(a) If either party becomes aware of any (i) infringement, anywhere in the world, of any TeneoBio Patent on account of a Third Party’s manufacture, use or sale of a CAR Product in the Field, including any BLA filed by a Third Party for a product that names a CAR Product as a reference product (or similar filing in a country other than the U.S.) or (ii) declaratory judgment action by a Third Party conducting any such manufacture, use or sale in the Field that alleges the invalidity, unenforceability or non-infringement of a TeneoBio Patent (collectively (i) and (ii), a “Product Infringement”), such party shall promptly notify the other party in writing to that effect.

(b) Licensee shall have the first right, but not the obligation, to bring an appropriate suit or take other action against any person or entity engaged in, or to defend against, such Product Infringement, […***…]; provided that, (i) for clarity, Licensee shall have no right to enforce the TeneoBio Patents, or take any other action in connection with the infringement thereof, outside of the Field, and (ii) Licensee shall not settle any suit or action in a manner that would negatively impact the TeneoBio Patents without TeneoBio’s prior written consent, which shall not be unreasonably withheld. If Licensee does not, within […***…] days after its receipt or delivery of notice under Section 3.5(a), commence a suit to enforce the applicable TeneoBio Patents in the Field, take other action to terminate such Product Infringement or initiate a defense against such Product Infringement, then TeneoBio shall have the right, but not the obligation, to commence any suit or take any action against, or defend against, such Product Infringement […***…]. In such event, Licensee shall take appropriate actions in order to enable TeneoBio to commence a suit or take the actions set forth in the preceding sentence. TeneoBio shall not settle any such suit or action in any manner that would negatively impact the TeneoBio Patents or that would limit or restrict the ability of Licensee to sell CAR Products anywhere in the world without the prior written consent of Licensee, which shall not be unreasonably withheld. Each party shall have the right, […***…], to be represented in any such suit by counsel of its own choice.

(c) Each party shall cooperate with and provide to the party enforcing any such rights under Section 3.5(b) reasonable assistance in such enforcement, at such enforcing party’s request and expense. TeneoBio further agrees to join, at Licensee’s expense, any such action brought by Licensee under Section 3.5(b) as a party plaintiff if required by applicable law to pursue such action. The enforcing party under Section 3.5(b) shall keep the other party regularly informed of the status and progress of such enforcement efforts, and shall reasonably consider the other party’s comments on any such efforts. Licensee may exercise any of its rights under this Section 3.5 through an Affiliate or Sublicensee.

(d) The party bringing or defending a claim, suit or action under Section 3.5(b) shall be solely responsible for any expenses incurred by such party as a result of such claim, suit or action. If such party recovers monetary damages in such claim, suit or action, such recovery shall be allocated first to the reimbursement of any expenses incurred by the parties in such litigation (including, for this purpose, a reasonable allocation of expenses of internal counsel), and any remaining amounts shall be allocated as follows: (i) if [...***…] is the enforcing or defending party, the remaining amounts will be retained by […***…]

***Certain Confidential Information Omitted

4.2 Selected Antibody License Fee. Licensee will pay TeneoBio a fee of […***…] (the “Selected Antibody License Fee”) upon its notification of TeneoBio of its selection of the Selected Antibodies. This Agreement will automatically terminate pursuant to Section 8.6 if the Selected Antibodies are not selected and the Selected Antibody License Fee paid within […***…] months after Licensee’s receipt of all materials, data and information that TeneoBio is obligated to provide under Section 2, or such longer period as the parties may agree in writing, such agreement not to be unreasonably withheld (the “Selection Period”).

4.3 Milestones. Licensee shall pay the following milestone payments to TeneoBio one time for each of the Allogenic Product and Autologous Product categories. The milestone payments will be due both upon (i) the first achievement of the applicable milestone event by any Allogenic Product, and (ii) the first achievement of the applicable milestone event by any Autologous Product:

(a) […***…] upon the first administration of each such type of CAR Product to the fourth human subject in a Phase I Trial.

(b) […***…] upon the first administration of each such type of CAR Product to a human subject in a Phase II Trial.

(d) […***…] upon the first Regulatory Approval of each such type of CAR Product in the first major market country in which such approval is received, where the major market countries are the […***…].

Milestone payments shall be payable regardless of whether the applicable milestone event was achieved by Licensee, an Affiliate, or a Sublicensee. Each milestone payment will be payable one time only per Allogenic Product and one time only per Autologous Product to achieve the applicable milestone event, regardless of the number of times the milestone event is achieved by an Allogenic Product or Autologous Product and regardless of the number of CAR Products to achieve the milestone event.

***Certain Confidential Information Omitted

TeneoBio – Poseida Therapeutics

Confidential

Licensee shall pay each milestone payment to TeneoBio within […***…]. days after the achievement of the corresponding milestone event. If a milestone event is achieved by an Allogenic Product or Autologous Product and payment with respect to any previous milestone event has not been made with respect to an Allogenic Product or Autologous Product, respectively, then such previous milestone event shall be deemed achieved for an Allogenic Product or Autologous Product, as applicable, and Licensee shall pay TeneoBio such unpaid previous milestone payment simultaneously with the milestone payment for the milestone event that was achieved. All milestone payments shall be accompanied by a summary report regarding the development activities that occurred with respect to the achievement of the applicable milestone event, subject to any confidentiality obligations of Licensee. The maximum amount payable under this Section 4.3 is twenty million five hundred thousand U.S. dollars ($20,500,000) for all Allogenic Products and twenty million five hundred thousand U.S. dollars ($20,500,000) for all Autologous Products, for a maximum total of forty-one million U.S. dollars ($41,000,000).

4.5 Records.

(a) Maintenance. Licensee shall keep (and shall use reasonable efforts to cause its Affiliates and each of its and their Sublicensees to keep) complete and accurate books and records pertaining to each such party’s achievement of milestone events and sale of CAR Products for a period of at least […***…] years after the relevant royalty or milestone payment is owed pursuant to this Agreement. The record-keeping obligations and inspection rights in this Section 4.5 shall supplement, and not replace or supersede, any similar rights or obligations hereunder.

(b) Annual Report. With respect to each CAR Product, within […***…] days after each anniversary of the Effective Date prior to First Commercial Sale of such CAR Product, Licensee shall deliver to TeneoBio a written report summarizing the progress of Licensee’s (and its Affiliates’ and, subject to any confidentiality obligations, Sublicensees’, and any relevant Third Parties’) research and development activities related to such CAR Product, and the Selected Antibodies and CAR Cells relevant to such CAR Product, during the previous […***…] month period.

(c) Records Examination. Licensee shall permit its books and records to be examined by an independent, nationally-recognized certified public accountant engaged by TeneoBio and reasonably acceptable to Licensee, upon reasonable notice during normal business hours, provided such examination is requested in writing at least […***…] business days in advance, solely for the purpose of verifying the accuracy of royalty and milestone reports and

***Certain Confidential Information Omitted

Confidential

payments under Sections 4.3 and 4.4. Such examination may not be more frequent than […***…]. per calendar year and may not include any books and records that were previously accessed under this Section 4.5(c), unless an examination reveals underpayment hereunder (in which case such previously accessed books and records shall again be subject to examination). Such accountant shall execute a confidentiality agreement with Licensee in customary form and shall only disclose to TeneoBio whether Licensee paid TeneoBio the correct amounts under Section 4.4 during the audited period and if not, any information necessary to explain the source of the discrepancy. Such examination is to be made at the expense of TeneoBio, except in the event that the results of the examination reveal an underpayment by Licensee of […***…] or more over the period being examined, in which case the reasonable costs and expenses of such examination shall be paid (or reimbursed to TeneoBio, if such amounts have already been paid) by Licensee. If the examination establishes that Licensee underpaid any amounts due hereunder, Licensee shall pay TeneoBio such deficiency within […***…] days after Licensee’s receipt of a written report thereof, including interest thereon at the rate set forth in Section 4.8, and, if applicable pursuant to the previous sentence, the costs and expenses of the examination. The results of any such examination shall be Licensee’s Confidential Information. Licensee shall use reasonable efforts to require its Affiliates and both its and their Sublicensees to afford TeneoBio the same rights as those granted TeneoBio in this Section 4.5(c).

4.6 Method of Payment. All payments due to TeneoBio under this Agreement shall be paid in United States Dollars by wire transfer to a bank in the U.S. designated in writing by TeneoBio. All references to “dollars” or “$” herein shall refer to United States Dollars. All amounts paid hereunder are non-refundable and non-creditable.

4.7 Taxes. Any amounts payable by Licensee to TeneoBio hereunder are exclusive of any and all applicable sales, use, excise, property, and other taxes, levies, duties or fees (collectively, “Taxes”), except for withholding taxes as set forth below. Each party shall be responsible for its own income taxes. Any withholding of taxes levied by tax authorities on the payments made by Licensee hereunder shall be borne by TeneoBio and deducted by Licensee, from the sums otherwise payable by it hereunder, and Licensee shall pay any such amounts to the proper tax authorities on behalf of TeneoBio. Licensee shall transmit to TeneoBio an official tax certificate or other evidence of such tax obligations together with proof of payment from the relevant tax authority of all amounts deducted and withheld sufficient to enable TeneoBio to claim such payment of taxes. Licensee agrees to cooperate with TeneoBio in the event TeneoBio claims exemption from such withholding or seeks deductions under any double taxation or other similar treaty or agreement from time to time in force and to cooperate with TeneoBio to minimize the amounts required to be withheld or deducted.

4.8 Late Payments. Any amount owed by Licensee to TeneoBio under this Agreement that is not paid within the applicable time period set forth herein shall accrue interest at the lower of (a) one and […***…] per month, or (b) the highest rate permitted under applicable law.

5. Confidentiality.

5.1 Definition. “Confidential Information” of the disclosing party means proprietary information, materials, and data of a financial, commercial, business or technical nature that the disclosing party (the “Disclosing Party”) has supplied or otherwise made available to the other party hereunder (the “Receiving Party”). The terms of this Agreement shall be deemed the Confidential Information of both parties and, except as provided in this Agreement, may not be disclosed by either party without the other party’s prior written consent. For clarity, the sequences of all Delivered Antibodies (including Selected Antibodies) are TeneoBio’s Confidential Information, and all information about the CAR Products developed by or on behalf of Licensee are Licensee’s Confidential Information (subject to the foregoing restriction regarding Selected Antibodies, but including Licensee’s selection of Selected Antibodies). In addition, any Confidential Information (as defined in the MTA) of a Party under that certain Materials Transfer Agreement between the Parties dated May 13, 2016 (the “MTA”) shall be such Party’s Confidential Information under this Agreement.

5.2 Obligations. The Receiving Party shall protect all Confidential Information against unauthorized disclosure to Affiliates and Third Parties with the same degree of care as the Receiving Party uses for its own similar information, but in no event less than a reasonable degree of care. The Receiving Party shall not use the Confidential Information except as necessary to exercise its rights and fulfill its obligations under this Agreement. The Receiving Party may disclose the Confidential Information only to its and its Affiliates’ respective directors, officers, employees, subcontractors, Sublicensees (in the case of Licensee as Receiving Party), consultants, contractors, attorneys, advisory boards, non-clinical and clinical investigators, accountants, and banks (collectively, “Recipients”), who have a need-to-know such information in order for Receiving Party to exercise its rights or fulfill its obligations under this Agreement, provided that the Receiving Party shall hold all Recipients to written obligations of confidentiality with terms and conditions at least as protective of the Confidential Information as those set forth in this Agreement (or in the case of attorneys and accountants, to obligations of nondisclosure and nonuse pursuant to the applicable rules of the profession), and Licensee may disclose the sequences of Selected Antibodies and related Confidential Information of TeneoBio in its patent or regulatory filings covering CAR Products. Receiving Party shall be liable for any breach of such written obligations or this Section 5 by its Recipients. Either party may disclose the terms and existence of this Agreement without the other party’s consent to its potential investors and acquirers, and in the case of Licensee to its potential Sublicensees and collaborators, on a confidential basis in connection with a potential investment, merger or acquisition, collaboration or license (as applicable) under appropriate confidentiality restrictions.

5.3 Exceptions. The obligations under this Section 5 shall not apply to any information to the extent the Receiving Party can demonstrate by competent evidence that such information:

(a) is (at the time of disclosure) or becomes (after the time of disclosure) generally known to the public through no breach of this Agreement by the Receiving Party or any Recipients to whom it disclosed such information;

TeneoBio – Poseida Therapeutics

Confidential

(b) was rightfully known by, or was otherwise in the rightful possession of, the Receiving Party prior to the time of disclosure by the Disclosing Party;

(c) is disclosed to the Receiving Party on a non-confidential basis by a Third Party who is entitled to disclose it without breaching any confidentiality obligation (directly or indirectly) to the Disclosing Party; or
