License and Other Agreements

MedImmune Limited License Agreement

In November 2017, the Company entered into a license agreement (“MedImmune License”) with MedImmune Limited (“MedImmune”). MedImmune is a wholly-owned subsidiary of AstraZeneca plc (“AstraZeneca”). Pursuant to the terms of the MedImmune License, MedImmune granted the Company exclusive global rights for the purpose of developing and commercializing products under the MedImmune License (“MedImmune licensed product”). The Company has made contingent milestone payments of $3.0 million and is obligated to make remaining contingent milestone payments totaling up to an aggregate of $15.0 million upon the achievement of clinical development and regulatory milestones. In addition, the Company will pay MedImmune tiered royalties ranging from mid-single-digit to low-teen percentages of net sales of any MedImmune licensed products and additional payments of up to $50.0 million in aggregate commercial milestones. The Company incurred no royalty costs under the MedImmune License in the three months ended March 31, 2021 and 2020.

The Company also must pay quarterly fees relating to technical services provided by MedImmune. The MedImmune License requires the Company to cooperate with MedImmune on commercial messaging of bentracimab and provides MedImmune with the return of rights to bentracimab if certain commercial diligence requirements are not achieved by the Company. In addition, the MedImmune License offers an option for third-party product storage costs. The Company incurred no third-party product storage costs in the three months ended March 31, 2021 and 2020. AstraZeneca is a stockholder of the Company.

Duke License Agreement

In October 2006, the Company entered into a license agreement with Duke University (“Duke”) (as amended, the “Duke License”). Pursuant to the Duke License, Duke granted to the Company an exclusive, worldwide license under certain patent rights and a non-exclusive license to know-how owned or controlled by Duke to develop and commercialize any products or processes covered under the Duke License (the “Duke licensed products”). The Duke License was amended in February 2016 to allow Duke to use the Company’s technology in the area of small-molecule oncologics. The Duke License is a worldwide, sublicensable agreement and remains in full effect for the life of the last-to-expire patents included in the patent rights, which is estimated to be 2030. The Company is required to apply for, prosecute and maintain all United States and foreign patent rights under the Duke License.

The Company is obligated to pay up to $2.2 million upon the achievement of clinical development and regulatory milestones and up to $0.4 million upon the achievement of commercial milestones. The Duke License may be terminated by Duke if the Company fails to meet certain clinical development and regulatory milestones within specified timeframes. As of March 31, 2021, the Company was in compliance with its development obligations.

The Company is required to use commercially reasonable efforts to develop one or more products or processes and introduce them into commercial markets. Duke will receive low single-digit royalty percentages on net sales of Duke licensed products by the Company or its sublicensee, with minimum aggregate royalties of $0.2 million payable following the Company’s achievement of certain commercial milestones. No sales of Duke licensed products or services have occurred since the effective date through March 31, 2021.

Certain alliance fee payments up to the greater of $0.3 million or a low double-digit percentage of the fees the Company receives from a third party in consideration of forming a strategic alliance may be required depending upon how the patent rights are commercialized. The Company must pay Duke the first $1.0 million of non-royalty payments it receives from a sublicensee, and thereafter a specified percentage of any additional non-royalty payments it receives, subject to certain conditions. If Duke receives revenue as a result of a license or sublicense to a third party in the field of small-molecule oncologics, it will pay the Company a specified percentage of the amount of such revenue in excess of $1.0 million. The Company incurred no costs under the Duke License in the three months ended March 31, 2021 and 2020.

Wacker License Agreement

In April 2019, the Company entered into a license agreement (“Wacker License Agreement”), with Wacker Biotech GmbH (“Wacker”), pursuant to which Wacker granted the Company an exclusive license under certain of Wacker’s intellectual property rights to use Wacker’s proprietary E. coli strain for the manufacture of bentracimab worldwide outside of specified Asian countries, and to commercialize bentracimab, if approved, manufactured by the Company or on the Company’s behalf using Wacker’s proprietary E. coli strain throughout the world. The Company has the right to grant sublicenses under the license, subject to certain conditions as specified in the Wacker License Agreement. Under the terms of the agreement, the Company is required to pay a fixed, nominal per-unit royalty, which is subject to adjustment, and an annual license fee in a fixed Euro amount in the low to mid six digits. The agreement will be in force for an indefinite period of time, and upon the expiration of the Company’s royalty obligations, the license will be considered fully paid and will convert to a non-exclusive license. Either party may terminate the Wacker License Agreement for breach if such breach is not cured within a specified number of days. The Company incurred $0.1 million under the Wacker License Agreement for the three months ended March 31, 2021 and 2020.

Viamet Asset Purchase Agreement

In January 2020, the Company entered into a purchase agreement ("PB6440 Agreement") with Viamet Pharmaceuticals Holdings, LLC and its wholly-owned subsidiary, Selenity Therapeutics (Bermuda), Ltd. (the "Sellers"), pursuant to which the Company acquired all of the assets and intellectual property rights related to the Sellers’ proprietary CYP11B2 inhibitor compound, formerly known as SE-6440 or VT-6440, and certain other CYP11B2 inhibitor compounds that are covered by the patent rights acquired by the Company under the PB6440 Agreement (together, "Compounds"). Under the terms of the PB6440 Agreement, the Company paid the Sellers an upfront fee of $0.1 million upon the closing of the transaction, and are required to pay the Sellers up to $5.1 million upon the achievement of certain development and intellectual property milestones with respect to certain product candidates that contain a Compound, up to $142.5 million upon the achievement of certain commercial milestones with respect to any approved product that contains a Compound and low- to mid-single digit royalty percentages on the net sales of approved products that contain a Compound, subject to customary reductions and offsets in specified circumstances. The Company incurred zero and $0.1 million in costs under the PB6440 Agreement for the three months ended March 31, 2021 and 2020, respectively.

BioVectra Supply Agreement

In March 2021, the Company entered into a supply agreement, ("BioVectra Agreement"), with BioVectra Inc. ("BioVectra") for the manufacture and supply by BioVectra of bulk drug substance for bentracimab for commercial distribution following regulatory approval, if obtained. Under the terms of the BioVectra Agreement, BioVectra has committed to maintaining capacity to manufacture an agreed number of batches of product each year, and the Company has committed to purchase a specified minimum number of batches of product per year (the "Minimum Annual Commitment"), although it is free to contract with third parties for the manufacture of bentracimab. The Company will pay a supply price per batch of bentracimab to be determined after the manufacturing process for the bentracimab is validated in accordance with the BioVectra Agreement, plus the cost of certain consumables, raw materials, and third-party testing.

Pursuant to the Minimum Annual Commitments, the Company is obligated to purchase a minimum of (i) approximately $14.0 million of batches of bentracimab in years 2022 through 2023, (ii) approximately $37.0 million of batches of

bentracimab in 2024, and (iii) approximately $48.0 million of batches of bentracimab in each of years 2025 through 2031. In the event the Company does not purchase the applicable Minimum Annual Commitment in a given year, it will be obligated to make a payment to BioVectra in an amount equal to the then-applicable supply price per batch multiplied by the difference between the Minimum Annual Commitment for such year and the number of batches of product it actually purchased in such year, except in the event that BioVectra was unable to deliver the number of batches ordered by the Company in such year. The Company will have the right to reduce the Minimum Annual Commitments for the year 2026 and subsequent years by up to a specified maximum percentage per year. Further, if the Company is only able to obtain regulatory approval for products incorporating bentracimab in only one of the United States or Europe, BioVectra and the Company have agreed to discuss in good faith an amendment to the BioVectra Agreement to reflect decreased requirements for product and impacts to the supply price to reflect lower volume commitments.
