PART I

This Annual Report on Form 10-K contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, or the Securities Act, Section 21E of the Securities Exchange Act of 1934, as amended, or the Exchange Act, and the Private Securities Litigation Reform Act of 1995, which are subject to the “safe harbor” created by those sections. Forward-looking statements are based on our management’s beliefs and assumptions and on information currently available to them. In some cases, you can identify forward-looking statements by words such as “may,” “will,” “should,” “could,” “would,” “expects,” “plans,” “anticipates,” “believes,” “estimates,” “projects,” “predicts,” “potential,” “intend” and similar expressions intended to identify forward-looking statements. Examples of these statements include, but are not limited to, statements regarding: our future operating expenses, our future losses, the potential success of our strategy as a royalty aggregator, the extent to which our issued and pending patents may protect our products and technology, the potential of our existing product candidates to lead to the development of commercial products, our ability to receive potential milestone or royalty payments under license and collaboration agreements and the probability, amount and timing of receipt of those payments, and our ability to satisfy our indebtedness obligations and our continuing obligation to pay quarterly cash dividends on our Series A Preferred Stock. These statements are based on assumptions that may not prove accurate. Actual results could differ materially from those anticipated due to certain risks inherent in the biotechnology industry and for our licensees engaged in the development of new products in a regulated market. Among other things: our product candidates subject to our out-license agreements are still being developed, and our licensees’ may require substantial funds to continue development which may not be available; if our therapeutic product candidates do not receive regulatory approval, our third-party licensees will not be able to market them; products or technologies of other companies may render some or all of our product candidates noncompetitive or obsolete; we do not know whether there will be, or will continue to be, a viable market for the products in which we have an ownership or royalty interest; even once approved, a product may be subject to additional testing or significant marketing restrictions, its approval may be withdrawn or it may be voluntarily taken off the market; and we and our licensees are subject to various state and federal healthcare related laws and regulations that may impact the commercialization of our product candidates and could subject us to significant fines and penalties; and certain of our technologies are in-licensed from third parties, so our capabilities using them may be restricted and subject to additional risks. These and other risks, including those related to current economic and financial market conditions, are contained principally in Item 1, Business; Item 1A, Risk Factors; Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations; and other sections of this Annual Report on Form 10-K. Factors that could cause or contribute to these differences include those discussed in Item 1A, Risk Factors, as well as those discussed elsewhere in this Annual Report on Form 10-K.

Forward-looking statements are inherently uncertain and you should not place undue reliance on these statements, which speak only as of the date that they were made. These cautionary statements should be considered in connection with any written or oral forward-looking statements that we may issue in the future. We do not undertake any obligation to release publicly any revisions to these forward-looking statements after completion of the filing of this Annual Report on Form 10-K to reflect later events or circumstances or to reflect the occurrence of unanticipated events.

All references to “portfolio” in this Annual Report on Form 10-K are to milestone and/or royalty rights associated with a basket of drug products in development.

Risk Factors Summary

Below is a summary of material factors that make an investment in our securities speculative or risky. Importantly, this summary does not address all of the risks and uncertainties that we face. Additional discussion of the risks and uncertainties summarized in this risk factor summary, as well as other risks and uncertainties that we face, can be found under “Risk Factors” in Part I, Item 1A of this Annual Report on Form 10-K. The below summary is qualified in its entirety by that more complete discussion of such risks and uncertainties. You should consider carefully the risks and uncertainties described under “Risk Factors” in Part I, Item 1A of this Annual Report on Form 10-K as part of your evaluation of the risks associated with an investment in our securities.

Table of Contents

The COVID-19 pandemic has adversely impacted and could materially and adversely impact in the future our licensees or royalty-agreement counterparties or their licensees, which could cause delays or elimination of our receipts of potential milestones and royalties under our licensing or royalty and milestone acquisition arrangements.
Our acquisitions of potential future royalty and/or milestone payments may not produce anticipated revenues and/or may be negatively affected by a default or bankruptcy of the licensor(s) or licensee(s) under the applicable license agreement(s) covering such potential royalties and/or milestones, and if such transactions are secured by collateral, we may be, or may become, under-secured by the collateral or such collateral may lose value and we will not be able to recuperate our capital expenditures associated with the acquisition.
Many of our potential royalty acquisitions may be associated with drug products that are in clinical development and have not yet been commercialized. To the extent that such products are not successfully developed and commercialized, our financial condition and results of operations may be negatively impacted. Acquisitions of potential royalties associated with development stage biopharmaceutical product candidates are subject to a number of uncertainties.
We depend on our licensees and royalty-agreement counterparties for the determination of royalty and milestone payments. While we typically have primary or back-up rights to audit our licensees and royalty-agreement counterparties, the independent auditors may have difficulty determining the correct royalty calculation, we may not be able to detect errors and payment calculations may call for retroactive adjustments. We may have to exercise legal remedies, if available, to resolve any disputes resulting from any such audit.
The lack of liquidity of our acquisitions of future potential milestones and royalties may adversely affect our business and, if we need to sell any of our acquired assets, we may not be able to do so at a favorable price, if at all. As a result, we may suffer losses. We have sustained losses in the past, and we expect to sustain losses in the foreseeable future.
Our royalty aggregator strategy may require that we register with the SEC as an “investment company” in accordance with the Investment Company Act of 1940. If we were to become an “investment company” and be subject to the restrictions of the 1940 Act, those restrictions would likely require significant changes in the way we do business and add significant administrative burdens to our operations.
Our royalty aggregator strategy may require us to raise additional funds to acquire milestone and royalty interests; we cannot be certain that funds will be available or available at an acceptable cost of capital, and if they are not available, we may be unsuccessful in acquiring milestone and royalty interests to sustain the business in the future.
We have significantly restructured our business and revised our business plan and there are no assurances that we will be able to successfully implement our revised business plan or successfully operate as a royalty aggregator.
Information available to us about the biopharmaceutical products underlying the potential royalties we buy may be limited and therefore our ability to analyze each product and its potential future cash flow may be similarly limited.
Our future income is dependent upon numerous potential milestone and royalty-specific assumptions and, if these assumptions prove not to be accurate, we may not achieve our anticipated rates of returns.
Reductions or declines in income from potential milestones and royalties, or significant reductions in potential milestone or royalty payments compared to expectations, or impairments in the value of potential milestones and royalties acquired could have a material adverse effect our financial condition and results of operations.
A large percentage of the calculated net present value of our portfolio is represented by a limited number of products. The failure of any one of these products to move forward in clinical development or commercialization may have a material adverse effect on our financial condition and results of operation.

Table of Contents

We rely heavily on license and collaboration relationships, and any disputes or litigation with our licensees, collaborators and their partners or termination or breach of any of the related agreements could reduce the financial resources available to us, including our ability to receive milestone payments and future potential royalty and other revenues. At any given time, we may be engaged in discussions with our licensees or collaborators regarding the interpretation of the payment and other provisions relating to products as to which we have milestones and potential royalty or other payment rights. Should any such discussions result in a disagreement regarding a particular product that cannot be resolved satisfactorily to us, we may end up being paid less than anticipated on such product which could materially adversely affect our financial condition, results of operation and future prospects.
Our potential milestone and royalty providers may rely on third parties to provide services in connection with their product candidate development and manufacturing programs. The inadequate performance by or loss of any of these service providers could affect our potential milestone and royalty providers’ product candidate development.
Certain of our technologies are in-licensed from third parties, so our and our licensees’ capabilities using them may be restricted and subject to additional risks.
Because many of the companies with which we do business also are in the biotechnology sector, the volatility of that sector can affect us indirectly as well as directly.
We may not be able to successfully identify and acquire potential milestone and royalty streams on other products, product candidates, or programs, or other companies to grow and diversify our business, and, even if we are able to do so, we may not be able to successfully manage the risks associated with integrating any such products, product candidates, programs or companies into our business or we may otherwise fail to realize the anticipated benefits of these acquisitions.
If our potential royalty providers’ therapeutic product candidates do not receive regulatory approval, our potential royalty providers will be unable to market them.
Our potential milestone and royalty providers face uncertain results of clinical trials of product candidates.
Our potential royalty providers may be unable to price their products effectively or obtain coverage and adequate reimbursement for sales of their products, which would prevent our licensees and potential royalty providers’ products from becoming profitable and negatively affect the royalties we may receive.
We do not know whether there will be, or will continue to be, a viable market for the product candidates in which we have an ownership, milestone or royalty interest.
If we and our potential royalty providers are unable to protect our intellectual property, in particular patent protection for principal products, product candidates and processes in which we have an ownership or royalty interest, and prevent the use of the covered subject matter by third parties, our potential royalty providers’ ability to compete in the market will be harmed, and we may not realize our profit potential.
We have a continuing obligation to pay quarterly dividends to holders of our Series A Preferred Stock, which will be an on-going expenditure for us and may limit our ability to borrow additional funds. 

Item 1.   Business

Overview and Strategy

XOMA Corporation (“XOMA”), a Delaware corporation, is a biotech royalty aggregator. We have a sizable portfolio of economic rights to future potential milestone and royalty payments associated with partnered pre-commercial therapeutic candidates. Our portfolio was built through licensing our proprietary products and platforms from our legacy discovery and development business, combined with acquisitions of rights to future milestones and royalties that we have

Table of Contents

made since our royalty aggregator business model was implemented in 2017. We expect that most of our future revenue will be based on payments we may receive for milestones and royalties related to these programs.

Our strategy is to expand our pipeline by acquiring additional potential milestone and royalty revenue streams on drug product candidates from third parties. Expanding our pipeline through these acquisitions can allow for further diversification across therapeutic areas and development stages. Our ideal target acquisitions are in pre-commercial stages of development, have an expected long duration of market exclusivity, high revenue potential, and are partnered with a large pharmaceutical or biopharmaceutical enterprise.

COVID-19

The COVID-19 pandemic continues to pose risks to our business as clinical trials industry-wide have slowed. Our business is dependent on the continued development and commercialization efforts of our licensees and our royalty agreement counterparties and their licensees. We have been monitoring and continue to monitor our portfolio programs for potential delays in underlying research programs and elections of our partners to continue or cease development. Delays in clinical trials and underlying research programs may lead to delayed revenue from milestones from our licensees and royalty agreement counterparties or, if certain research programs are discontinued, we may recognize impairment charges for our royalty receivables. COVID-19, the related variants, and the timing of vaccine distribution may impact our underlying programs in a variety of ways which are unknown in length and scope at this time.

Acquisitions

Royalty Purchase Agreement with Agenus, Inc.

In September 2018, we entered into a royalty purchase agreement (the “Agenus Royalty Purchase Agreement”) with Agenus, Inc. (“Agenus”). Under the Agenus Royalty Purchase Agreement, we purchased from Agenus the right to receive 33% of the future royalties due to Agenus from Incyte (net of certain royalties payable by Agenus to a third party) and 10% of all future developmental, regulatory and sales milestones on sales of six Incyte immuno-oncology assets. In addition, we purchased from Agenus the right to receive 33% of the future royalties due to Agenus from Merck and 10% of all future developmental, regulatory and sales milestones on sales of MK-4830, an immuno-oncology product currently in clinical development. Pursuant to the Agenus Royalty Purchase Agreement, our share in future potential development, regulatory and commercial milestones is up to $59.5 million and the royalties have no limit. Under the terms of the Agenus Royalty Purchase Agreement, we paid Agenus $15.0 million. We financed $7.5 million of the purchase price with a three-year term loan under our Loan and Security Agreement with Silicon Valley Bank (“SVB”) dated May 7, 2018.

In November 2020, MK-4830 advanced to Phase 2 development stage. As a result of the advancement, Agenus earned a $10.0 million clinical development milestone pursuant to its license agreement with Merck, of which we earned $1.0 million.

Royalty Purchase Agreement with Bioasis Technologies, Inc.

In February 2019, we entered into a royalty purchase agreement with Bioasis Technologies, Inc. (the “Bioasis Royalty Purchase Agreement”) and certain affiliates (collectively “Bioasis”). Under the Bioasis Royalty Purchase Agreement, we purchased potential future milestone, royalty and option fee payment rights from Bioasis for product candidates that are being developed pursuant to a License Agreement between Bioasis and Prothena Biosciences Limited. Under the terms of the Bioasis Royalty Purchase Agreement, we paid Bioasis an upfront cash payment of $0.3 million and will be required to make contingent future cash payments of up to $0.2 million to Bioasis if and when the licensed product candidates reach certain development milestones. As of December 31, 2020, none of the development milestones had been achieved. In addition, we were granted an option to purchase a 1% royalty right on the next two license agreements entered into between Bioasis and third-party licensees subject to certain payments and conditions as well as a right of first negotiation on subsequent Bioasis license agreements with third parties.

In November 2020, we entered into a second royalty purchase agreement with Bioasis (the “Second Bioasis Royalty Purchase Agreement”). Under the Second Bioasis Royalty Purchase Agreement, we purchased potential future milestone and other payments, and royalty rights from Bioasis for product candidates that are being developed pursuant to a research collaboration and license agreement between Bioasis and Chiesi Farmaceutici S.p.A. (“Chiesi”). We paid Bioasis $1.2 million upon closing of the Second Bioasis Royalty Purchase Agreement for the purchased rights.

Royalty Purchase Agreement with Aronora, Inc.

In April 2019, we entered into a royalty purchase agreement with Aronora, Inc. (the “Aronora Royalty Purchase Agreement”), a private research and development company headquartered in Portland, Oregon. Under the Aronora Royalty Purchase Agreement, we purchased from Aronora the rights to potential royalties and a portion of upfront, milestone, and option payments associated with five anti-thrombotic hematology drug products in development: three candidates subject to Aronora’s collaboration with Bayer Pharma AG (“Bayer”) (the “Bayer Products”) and two additional early-stage candidates (the “non-Bayer Products”).

Under the terms of the Aronora Royalty Purchase Agreement, we made a $6.0 million upfront payment to Aronora when the transaction closed on June 26, 2019, and in September 2019 we made an additional $3.0 million payment for the three Bayer Products that were active as of September 1, 2019. Pursuant to the Aronora Royalty Purchase Agreement, if we receive $250.0 million in cumulative royalties on net sales per product, we will be required to pay associated tiered milestones payments to Aronora in an aggregate amount of up to $85.0 million per product. The tiered milestones will be paid based on various royalty tiers prior to reaching $250.0 million in cumulative royalties on net sales per product. We will retain royalties per product in excess of $250.0 million. We will receive, on average, low single-digit royalties on future sales of the Bayer Products and 10% of all future developmental, regulatory and sales milestones related to the Bayer Products. In addition, we purchased from Aronora the right to receive low-single digit percentage of net sales of the non-Bayer Products and 10% of all future payments, including upfront payments, option payments and developmental, regulatory and sales milestone payments on potential future sales of the non-Bayer Products. We financed $4.5 million of the purchase price with a three-year term loan under our Loan and Security Agreement with SVB dated May 7, 2018. In July 2020, Bayer elected to not exercise its option on the third Bayer Product and that product is now subject to the same economics as the non-Bayer Products.

Royalty Purchase Agreement with Palobiofarma, S.L.

In September 2019, we entered into a royalty purchase agreement (the “Palo Royalty Purchase Agreement”) with Palobiofarma, S.L, (“Palo”). Pursuant to the Palo Royalty Purchase Agreement, we acquired the rights to potential royalty payments in low single digit percentages of aggregate net sales associated with six drug candidates in various clinical development stages, targeting the adenosine pathway with potential applications in solid tumors, non-Hodgkin’s lymphoma, asthma/chronic obstructive pulmonary disease, ulcerative colitis, idiopathic pulmonary fibrosis, lung cancer, psoriasis, nonalcoholic steatohepatitis and other indications (the “Palo Licensed Products”) that are being developed by Palo. Novartis Pharma AG (“Novartis”) is a development partner on NIR178, one of the Palo Licensed Products, and NIR178 is being developed pursuant to a license agreement between Palo and Novartis. Under the terms of the Palo Royalty Purchase Agreement, we paid Palo $10.0 million for the rights to potential royalty payments on future sales of the Palo Licensed Products. We financed $5.0 million of the purchase price with a three-year term loan under our Loan and Security Agreement with SVB dated May 7, 2018.

Selected Programs Underlying Our Core Pipeline

Historically, we have licensed product candidates or provided research and development collaboration services to world-class organizations, such as Novartis and Takeda, in pursuit of new antibody products under which we are eligible to receive potential future milestone payments and royalties. The following is a summary of material license and collaboration agreements that represent a significant component of our core pipeline.

Novartis – Anti-TGFβ Antibody

In September 2015, we and Novartis International Pharmaceutical Ltd. (“Novartis International”) entered into a license agreement (the “Anti-TGFβ Antibody License Agreement”) under which we granted Novartis International an exclusive, worldwide, royalty-bearing license to our anti-TGFβ antibody program (“NIS793”). Novartis International is solely responsible for the development and commercialization of the antibodies and products containing the antibodies arising from this program.

Under the Anti-TGFβ Antibody License Agreement, we received a $37.0 million upfront fee, and are eligible to receive up to a total of $480.0 million in development, regulatory and commercial milestones. We also are eligible to receive royalties on sales of licensed products, which are tiered based on sales levels and have percentage rates ranging from mid-single digits to low-teens. This program is currently in clinical testing.

In October 2020, the first patient was dosed in Novartis International's NIS793 Phase 2 clinical trial and we earned a $25.0 million milestone payment. As specified under the terms the Anti-TGFβ Antibody License Agreement, we received $17.7 million in cash and the remaining balance of $7.3 million was recognized as a reduction to our debt obligation to Novartis. We recorded $25.0 million as revenue from contracts with customers in the consolidated statement of operations and comprehensive income (loss) in the fourth quarter of 2020.

Novartis – Anti-CD40 Antibody

In February of 2004, we entered into an exclusive, worldwide, multi-product collaboration agreement with Chiron Corporation (“Chiron”) to research, develop and commercialize multiple antibody products for the treatment of cancer, and such agreement was replaced with a more detailed agreement entered in May of 2005 (the “Chiron Collaboration Agreement”). The Chiron Collaboration Agreement was a risk-sharing arrangement whereby Chiron and XOMA shared expenses and revenues on a 70-30 basis, with XOMA’s share being 30%. Financial terms included a loan facility from Chiron to XOMA, secured by XOMA’s 30% ownership interest in the collaboration, of up to $50.0 million to fund up to 75% of our share of expenses beginning in 2005.

In October 2005, Chiron announced it had entered into a definitive merger agreement with Novartis AG (“Novartis”) under which Novartis acquired all of the shares of Chiron that it did not already own. This transaction closed in 2006 at which time Novartis acquired Chiron’s interest in the Chiron Collaboration Agreement. In July of 2008, Novartis and XOMA restructured the Chiron Collaboration Agreement, which involved six development programs including iscalimab, a fully human anti-CD40 antagonist antibody intended as a treatment for B-cell mediated diseases, including malignancies and autoimmune diseases. As part of the restructuring, Novartis Vaccines and Diagnostics, Inc. (“NVDI”), the successor to Chiron, was granted, among other things, control over the ongoing product development collaborations remaining thereunder, including iscalimab. In September 2015, the parties agreed to reduce the royalty-style payments that XOMA is eligible to receive on sales of NVDI’s clinical stage anti-CD40 antibodies (such as iscalimab). These royalty-style payments are tiered based on sales levels and now have percentage rates ranging from mid-single digit to low-teens.

Our right to royalty-style payments expires on the later of the expiration of any licensed patent covering each product or 10 years from the first commercial sale of each product in each country. Novartis is currently conducting clinical testing of iscalimab in several indications.

Novartis – Gevokizumab

In August 2017, we and Novartis entered into a license agreement (the “Gevokizumab License Agreement”), under which we granted Novartis an exclusive, worldwide, royalty-bearing license to gevokizumab (“VPM087”) (a clinical stage product candidate) and related know-how and patents. Under the terms of the Gevokizumab License Agreement, Novartis is solely responsible for the development and commercialization of VPM087 and products containing such antibody.

Under the Gevokizumab License Agreement, we received total consideration of $30.0 million in 2017 for the license and rights granted to Novartis. Of the total consideration, $15.7 million was paid in cash and $14.3 million (equal to €12.0 million) was paid by Novartis Institutes for Biomedical Research, Inc. (“NIBR”), on our behalf, to settle our loan with Les Laboratories Servier (“Servier”). In addition, NIBR extended the maturity date on our debt to Novartis to September 30, 2022. We also received $5.0 million related to the sale of 539,131 shares of our common stock, at a price per share of $9.2742. Based on the achievement of pre-specified criteria, we are eligible to receive up to $438.0 million in development, regulatory and commercial milestones. We are also eligible to receive royalties on sales of licensed products, which are tiered based on sales levels and have percentage rates ranging from mid-single digit to mid-teens. This program is in early clinical testing.

Unless terminated earlier, the Gevokizumab License Agreement will remain in effect, on a country-by-country and product-by-product basis, until Novartis’ royalty obligations end. The Gevokizumab License Agreement contains customary termination rights relating to material breach by either party. Novartis also has a unilateral right to terminate the Gevokizumab License Agreement on a product-by-product and country-by-country basis or in its entirety with six months’ prior written notice.

Takeda

In November 2006, we entered into a collaboration agreement with Takeda Pharmaceutical Company Limited (“Takeda”) (the “Takeda Collaboration Agreement”) under which we agreed to discover and optimize therapeutic antibodies against multiple targets selected by Takeda.

Under the Takeda Collaboration Agreement, we may receive additional milestone payments aggregating up to $19.0 million relating to TAK-079 (mezagitamab) and a 4% royalty on future sales of all products subject to this license, including TAK-169, which entered a phase 1 study in February 2020. Our right to milestone payments expires on the later of the receipt of payment from Takeda of the last amount to be paid under the agreement or the cessation by Takeda of all research and development activities with respect to all program antibodies, collaboration targets or collaboration products. Our right to royalties expires on the later of 13.5 years from the first commercial sale of each royalty-bearing discovery product or the expiration of the last-to-expire licensed patent (or 12 years from first commercial sale if there is significant generic competition post patent-expiration).

Table of Contents

In February 2009, we expanded our existing collaboration to provide Takeda with access to multiple antibody technologies, including a suite of research and development technologies and integrated information and data management systems. We may receive milestones of up to $3.3 million per discovery product candidate and low single-digit royalties on future sales of all antibody products subject to this license. Our right to milestone payments expires on the later of the receipt of payment from Takeda of the last amount to be paid under the agreement or the cessation by Takeda of all research and development activities with respect to all program antibodies, collaboration targets or collaboration products. Our right to royalties expires on the later of 10 years from the first commercial sale of such royalty-bearing discovery product or the expiration of the last-to-expire licensed.

In November 2020, the first patient was dosed in Takeda’s Phase 2 study of mezagitamab and we earned a $2.0 million milestone payment from Takeda.

Rezolute

In December 2017, we entered into a license agreement with Rezolute, Inc. (formerly AntriaBio, Inc.) (“Rezolute”) pursuant to which we granted an exclusive global license to Rezolute to develop and commercialize products containing X358 (now RZ358), a Phase 2 product candidate, for all indications. We and Rezolute also entered into a common stock purchase agreement.

Under the terms of the license agreement, Rezolute is responsible for all development, regulatory, manufacturing and commercialization activities associated with RZ358 and is required to make certain clinical, regulatory and annual net sales milestone payments to us of up to $232.0 million in the aggregate based on the achievement of pre-specified criteria. Rezolute is also obligated to pay us royalties ranging from the high single digits to the mid-teens based upon annual net sales of RZ358. Rezolute is obligated to take customary steps to advance RZ358, and to meet certain spending requirements on an annual basis for the program until a marketing approval application for RZ358 is accepted by the Food and Drug Administration (“FDA”). Rezolute’s obligation to pay royalties with respect to a particular licensed product and country will continue for the longer of the date of expiration of the last valid patent claim covering the product in that country, or twelve years from the date of the first commercial sale of the product in that country. Rezolute’s future royalty obligations in the United States will be reduced by 20% if the manufacture, use or sale of a licensed product is not covered by a valid XOMA patent claim, until such a claim is issued.

Under the terms of the license agreement, Rezolute is required to pay us a low single-digit royalty on sales of Rezolute’s other products from its existing programs, currently in preclinical and early clinical stages. Rezolute’s obligation to pay royalties with respect to a particular Rezolute product and country will continue for the longer of twelve years from the date of the first commercial sale of the product in that country or for so long as Rezolute or its licensee is selling such product in such country, provided that such royalty will terminate upon the termination of the licensee’s obligation to make payments to Rezolute based on sales of such product in such country.

We also granted Rezolute an option through June 1, 2019 for an exclusive license for their choice of one of our preclinical insulin receptor monoclonal antibody fragments, including X129. On June 1, 2019, such option expired unexercised. The license agreement contains customary termination rights relating to material breach by either party. Rezolute also has a unilateral right to terminate the license agreement in its entirety on ninety-days’ notice at any time.

Rezolute License Agreement - First Amendment

In March 2018, we and Rezolute amended the license agreement and common stock purchase agreement. Pursuant to the as-amended terms of the license agreement and common stock purchase agreement, Rezolute was required to pay us $6.0 million in cash, to issue us $8.5 million worth of its common stock, and to issue us 7,000,000 shares of its common stock, contingent on the completion of its financing activities. Further, in the event that Rezolute did not complete a financing that raised at least $20.0 million in aggregate gross proceeds (“Qualified Financing”) by March 31, 2019 (the “2019 Closing”), it would issue to us an additional number of shares of its common stock equal to $8.5 million divided by the weighted average of the closing bid and ask prices or the average closing prices of Rezolute’s common stock on the ten-day trading period prior to March 31, 2019. Finally, if Rezolute was unable to complete a Qualified Financing by

9

Table of Contents

March 31, 2020, it was obliged to pay us $15.0 million in order to maintain the license. Under the common stock purchase agreement, Rezolute granted us the right and option to sell the greater of (i) 5,000,000 shares of common stock or (ii) one third of the aggregate shares held by us upon failure by Rezolute to list its shares of its common stock on the Nasdaq Stock Market or a similar national exchange on or prior to December 31, 2019.

During the year ended December 31, 2018, Rezolute closed a debt financing activity for gross proceeds of $4.0 million, which triggered the Initial Closing, and completed an Interim Financing Closing, as defined in the common stock purchase agreement. These financing activities resulted in receipt of 8,093,010 shares of Rezolute’s common stock and cash of $0.5 million. Under the amended license agreement, we were also entitled to receive $0.3 million of reimbursable technology transfer expenses from Rezolute.

Rezolute License Agreement - Second Amendment

In January 2019, we and Rezolute further amended the license agreement and common stock purchase agreement. The license agreement was amended to eliminate the requirement that equity securities be issued to us upon the closing of the Qualified Financing and to replace it with a requirement that Rezolute: (1) make five cash payments to us totaling $8.5 million following the closing of a Qualified Financing on or before specified staggered future dates through September 2020 (the “Future Cash Payments”); and (2) provide for early payment of the Future Cash Payments (only until the above referenced $8.5 million is reached) by making cash payments to us equal to 15% of the net proceeds of each future financing following the closing of the Qualified Financing, with such payments to be credited against any remaining unpaid Future Cash Payments in reverse order of their scheduled payment date. In accordance with the terms of the license agreement, we received an additional $5.5 million in cash upon the closing of the Qualified Financing in February 2019. In July and August 2019, Rezolute received additional cash through two common stock financing events, resulting in early payment of $3.4 million of unrecognized Future Cash Payments. In addition, we received the $1.5 million and $1.0 million payments due in September 2019 and December 2019, respectively, resulting in a total of $11.4 million in cash received from Rezolute for Qualified Financing and Future Cash Payments in the year ended December 31, 2019. As of December 31, 2019, we had an outstanding receivable of $2.6 million representing the current estimate of the Future Cash Payments expected to be received from Rezolute. During the year ended December 31, 2019, we recognized $14.0 million as revenue from Rezolute.

The license agreement amendment also revised the amount Rezolute is required to expend on development of RZ358 and related licensed products and revised provisions with respect to Rezolute’s diligence efforts in conducting clinical studies. Lastly, the common stock purchase agreement was amended to remove certain provisions related to the issuance of equity to us in accordance with the new provisions regarding the Future Cash Payments in the license agreement. Specifically, the common stock purchase agreement was amended to provide XOMA the right to sell up to 5,000,000 shares of Rezolute common stock currently held by us, back to Rezolute if it fails to list its shares of common stock on the Nasdaq Stock Market or a similar national exchange on or prior to December 31, 2019. Only 2,500,000 shares may be sold back to Rezolute during calendar year 2020. Any such shares may be sold back to Rezolute at the average of the closing bid and asked prices of its common stock quoted on its principal trading market on the date of such put option exercise. As of December 31, 2019, Rezolute failed to list its shares of common stock on the Nasdaq Stock Market or a similar exchange.

Rezolute License Agreement - Third Amendment

In March 2020, we and Rezolute further amended the license agreement to extend the payment schedule for the remaining $2.6 million in Future Cash Payments. The amendment to the payment terms was in response to Rezolute’s need to preserve cash as a result of the COVID-19 pandemic. The extended payment schedule did not impact the total amount due, but instead, spread the $2.6 million into seven quarterly payments to be paid through September 30, 2021. The amended license agreement required that in the event Rezolute completed a Qualified Financing at any time between March 31, 2020 and the date of the final payment, Rezolute would pay all amounts outstanding within fifteen days following the closing of the Qualified Financing.  

In October 2020, Rezolute completed a private placement of its equity securities with gross proceeds of $41.0 million, which was considered a Qualified Financing event under the third amendment of the Rezolute license agreement

10

Table of Contents

(the “Third Amendment”). The Qualified Financing resulted in acceleration of the remaining receivables of $1.4 million due from Rezolute, and we received the entire amount in October 2020.

During the quarter ended December 31, 2020, Rezolute completed a 1:50 reverse stock split of its common shares and started trading on the Nasdaq Stock Market. As a result, our holding of Rezolute common stock was reduced from 8,093,010 shares to 161,860 shares.

Proprietary Product Candidates

We have a pipeline of unique monoclonal antibodies and technologies available to license to pharmaceutical and biotechnology companies to further their clinical development. A summary of these product candidates is provided below:

PTH1R program. We have generated an anti-parathyroid receptor pipeline that includes several functional antibody antagonists targeting PTH1R, a G-protein-coupled receptor involved in the regulation of calcium metabolism. These antibodies have shown promising efficacy in in vivo studies and could potentially address unmet medical needs, including primary hyperparathyroidism and humoral hypercalcemia of malignancy (“HHM”). HHM is present in many advanced cancers and is caused by high serum calcium due to increased levels of the PTH1R ligand PTH-related peptide (“PTHrP”). Current HHM treatments often fall short and many cancer patients die from ‘metabolic death’. Our PTH1R antibodies could be beneficial for the treatment of HHM.
XMetA is an insulin receptor-activating antibody designed to provide long-acting reduction of hyperglycemia in Type 2 diabetic patients, potentially reducing the advancement to a number of insulin injections needed to control their blood glucose levels.
X213 (formerly LFA 102) is an allosteric inhibitor of prolactin action. It is a humanized IgG1-Kappa monoclonal antibody that binds to the extracellular domain of the human prolactin receptor with high affinity at an allosteric site. The antibody has been shown to inhibit prolactin-mediated signaling, and it is potent and similarly active against several animal and human prolactin receptors.

Technologies Available for Non-Exclusive License

We have a set of antibody discovery, optimization and development technologies available for licensing, including:

ADAPT™ (Antibody Discovery Advanced Platform Technologies): proprietary human antibody phage display libraries, integrated with yeast and mammalian display, which can be integrated into antibody discovery programs through license agreements. We believe access to ADAPT™ Integrated Display offers a number of benefits because it enables the diversity of phage libraries to be combined with accelerated discovery due to rapid immunoglobulin (“IgG”) reformatting and fluorescence-activated cell sorting based screening using yeast and mammalian display. This increases the probability of success in finding rare and unique functional antibodies directed to targets of interest.
ModulX™: technology which allows modulation of biological pathways using monoclonal antibodies and offers insights into regulation of signaling pathways, homeostatic control, and disease biology. Using ModulX™, we have generated product candidates with novel mechanisms of action that specifically alter the kinetics of interaction between molecular constituents (e.g. receptor-ligand). ModulX™ technology enables expanded target and therapeutic options and offers a unique approach in the treatment of disease.
OptimX™ technologies:
Human Engineering™ (“HE™”): a proprietary humanization technology that allows modification of non-human monoclonal antibodies to reduce or eliminate detectable immunogenicity and make them

11

Table of Contents

suitable for medical purposes in humans. The technology uses a unique method developed by us, based on analysis of the conserved structure-function relationships among antibodies. The method defines which residues in a non-human variable region are candidates to be modified. The result is an HE™ antibody with preserved antigen binding, structure and function that has eliminated or greatly reduced immunogenicity. HE™ technology was used in development of gevokizumab (VPM087) and certain other antibody products.
Targeted Affinity Enhancement™ (“TAE™”): a proprietary technology involving the assessment and guided substitution of amino acids in antibody variable regions, enabling efficient optimization of antibody binding affinity and selectivity. TAE™ generates a comprehensive map of the effects of amino acid mutations in the complementarity-determining region likely to impact binding. The technology has been licensed to a number of companies.

Debt Agreements

Novartis

In connection with the collaboration between XOMA and Novartis AG (then Chiron Corporation), a secured note agreement was executed in May 2005. The note agreement is secured by our interest in the collaboration and was due and payable in full on June 21, 2015. In June 2015, we and NVDI, who assumed the note agreement, agreed to extend the maturity date of our secured note agreement from June 21, 2015 to September 30, 2015, which was then subsequently extended to September 30, 2020. In September 2017, in connection with the Gevokizumab License Agreement with Novartis, we and NIBR, who assumed the note agreement from NVDI, executed an amendment to the note agreement under which we further extended the maturity date of the note to September 30, 2022.

In October 2020, the first patient was dosed in Novartis International’s NIS793 Phase 2 clinical trial NCT04390763 and we earned a $25.0 million milestone payment, of which $7.3 million was recognized as a reduction to the debt obligation to Novartis.

As of December 31, 2020, the outstanding principal balance under this note agreement totaled $9.1 million.

Silicon Valley Bank Loan Agreement

In May 2018, we executed a loan and security agreement (the “Loan Agreement”) with SVB. Under the Loan Agreement, upon our request, SVB may make advances available to us of up to $20.0 million. We were able to borrow advances under the Term Loan from May 7, 2018 (the “Effective Date”) until the earlier of March 31, 2019 or an event of default.

In March 2019, we and SVB amended the Loan Agreement to extend the draw period from March 31, 2019 to March 31, 2020. Our draw period lapsed on March 31, 2020 with no further extension. In connection with the amendment, we issued a second warrant to SVB, which is exercisable in whole or in part for up to an aggregate of 4,845 shares of common stock with an exercise price of $14.71 per share.

In September 2018, we borrowed $7.5 million under the Loan Agreement in connection with the Agenus royalty purchase agreement. In June and September 2019, we borrowed advances of $3.0 million and $1.5 million for the upfront payment and the contingent consideration under the Aronora Royalty Purchase Agreement, respectively. In September 2019, we borrowed an additional $5.0 million in connection with the Palo Royalty Purchase Agreement.

As of December 31, 2020, the outstanding principal balance of the debt under the Loan Agreement was $12.2 million.

Competition

The biotechnology and pharmaceutical industries are subject to continuous and substantial technological change. Some of the drugs our licensees or royalty partners are developing may compete with existing therapies or other drugs in development by other companies. Furthermore, academic institutions, government agencies and other public and private organizations conducting research may seek patent protection with respect to potentially competing products or technologies and may establish collaborative arrangements with our licensees’ or royalty partners’ competitors. There can be no assurance that developments by others, including, without limitation, the development of generics or biosimilars, will not render our, or our licensees’, products or technologies obsolete or uncompetitive.

Additionally, our royalty aggregator model faces competition on at least two fronts. First, there are other companies, funds and other investment vehicles seeking to aggregate royalties or provide alternative financing to development-stage biotechnology and pharmaceutical companies. The competitive companies, funds and other investment vehicles may have a lower target rate of return, a lower cost of capital or access to greater amounts of capital and thereby may be able to acquire assets that we are also targeting for acquisitions. Second, existing or potential competitors to our partners and licensees’ products, particularly large pharmaceutical companies, may have greater financial, technical and human resources than our licensees. Accordingly, these competitors may be better equipped to develop, manufacture and market products. Many of these companies also have extensive experience in preclinical testing and human clinical trials, obtaining FDA and other regulatory approvals and manufacturing and marketing pharmaceutical products.

For a discussion of the risks associated with competition, see below under “Item 1A. Risk Factors.”

Government Regulation and Environmental Matters

The research and development, manufacturing and marketing of pharmaceutical products are subject to regulation by numerous governmental authorities in the United States and other countries. We and our partners and licensees, depending on specific activities performed, are subject to these regulations. In the United States, pharmaceuticals are subject to regulation by both federal and various state authorities, including the FDA. The Federal Food, Drug and Cosmetic Act and the Public Health Service Act govern the testing, manufacture, safety, efficacy, labeling, storage, record keeping, approval, advertising and promotion of pharmaceutical products and there are often comparable regulations that apply at the state level. There are similar regulations in other countries as well. For both currently marketed and products in development, failure to comply with applicable regulatory requirements can, among other things, result in delays, the suspension of regulatory approvals, as well as possible civil and criminal sanctions. Development stage products in our portfolio require approval by the FDA before we will recognize any royalties from sales. In addition, changes in existing regulations could have a material adverse effect on us or our partners.

We believe that there are no compliance issues with laws and regulations that have been enacted or adopted regulating the discharge of materials into the environment, or otherwise relating to the protection of the environment, that have adversely affected, or are reasonably expected to adversely affect, our business, financial condition and results of operations, and we do not currently anticipate material capital expenditures arising from environmental regulation. We believe that climate change could present risks to our business. Some of the potential impacts of climate change to our business include increased operating costs due to additional regulatory requirements and the risk of disruptions to our business. We do not believe these risks are material to our business at this time.

For a discussion of the risks associated with government regulations, see below under “Item 1A. Risk Factors.”

Intellectual Property

Intellectual property is important to our business and our future income streams will depend in part on our, and our partners and licensees’, ability to obtain issued patents and to operate without infringing on the proprietary rights of others. We hold and have filed applications for a number of patents in the United States and internationally to protect our products and technology. We also have obtained or have the right to obtain licenses to, or income streams based on, certain patents and applications filed by others. However, the patent position of biotechnology companies generally is highly uncertain and consistent policy regarding the breadth of allowed claims has not emerged from the actions of the U.S. Patent

and Trademark Office with respect to biotechnology patents. Accordingly, no assurance can be given that our, or our partners or licensees’ patents will afford protection against competitors with similar products or others will not obtain patents claiming aspects similar to those covered by our, or our partners’ or licensees’ patent applications.

If certain patents issued to others are upheld or if certain patent applications filed by others are issued and upheld, our partners and licensees may require certain licenses from others to develop and commercialize certain potential products incorporating our technology. There can be no assurance that such licenses, if required, will be available on acceptable terms.

We protect our proprietary information, in part, by confidentiality agreements with our employees, consultants and partners. These parties may breach these agreements, and we may not have adequate remedies for any breach. To the extent that we or our consultants or partners use intellectual property owned by others, we may have disputes with our consultants or partners or other third parties, as to the rights in related or resulting know-how and inventions.

Concentration of Risk

Our business model is dependent on third parties achieving specified development milestones and product sales. Our pipeline currently includes over 65 fully-funded programs from which we could potentially receive royalties or other payments if the programs achieve marketability. Novartis is developing several of the programs in our pipeline. While we do not expect the discontinuation of any one program would have a material impact on our business, the discontinuation of all programs by Novartis could have a material effect on our business and financial condition.

Organization

We were incorporated in Delaware in 1981 and became a Bermuda-exempted company in December 1998. Effective December 31, 2011, we changed our jurisdiction of incorporation from Bermuda to Delaware and changed our name from XOMA Ltd. to XOMA Corporation. When referring to a time or period before December 31, 1998 or after December 31, 2011, the terms “Company” and “XOMA” refer to XOMA Corporation, a Delaware corporation; when referring to a time or period between December 31, 1998 and December 31, 2011, such terms refer to XOMA Ltd., a Bermuda company.

Our principal executive offices are located at 2200 Powell Street, Suite 310, Emeryville, California 94608. Our telephone number at our principal executive offices is (510) 204-7200. Our website address is www.xoma.com. The information found on our website is not part of this or any other report filed with or furnished to the Securities and Exchange Commission (“SEC”).

Human Capital Resources

We rely on a small number of skilled, experienced, and innovative employees to conduct the operations of our company. As of March 5, 2021, we employed 10 full-time employees primarily engaged in executive, business development, legal, finance and administrative positions.

15

Table of Contents

The success of our business is fundamentally connected to the well-being of our employees. We provide robust compensation and benefits programs to help meet the needs of our employees. In addition to salaries, these programs include potential annual discretionary bonuses, broad-based equity awards, a 401(k) plan, healthcare and insurance benefits, paid time off, family leave, and flexible work schedules, among others. These benefits provide our employees choices where possible so they can customize their benefits to meet their needs and the needs of their families, as well as access to tools and resources to help them improve or maintain their health status and encourage engagement in healthy behaviors to improve their physical and mental health.

In response to the COVID-19 pandemic and “shelter in place” and similar orders issued by state and local governments, we have temporarily restricted access to our office in California, as well as suspended any non-essential business travel. Our employees are conducting their work remotely, and they otherwise have minimal presence in our offices for essential activities. The safety, health and well-being of our employees is paramount. As such, we will consider ongoing government regulations and local health conditions before lifting any restrictions on travel or allowing any gatherings at our offices.  

Item 1A.       Risk Factors

The following risk factors and other information included in this Annual Report should be carefully considered. The risks and uncertainties described below are not the only ones we face. Additional risks and uncertainties not presently known to us also may impair our business operations. If any of the following risks occur, our business, financial condition, operating results and cash flows could be materially adversely affected.

Risks Related to our Royalty Aggregator Strategy

The COVID-19 pandemic has adversely impacted and could materially and adversely impact in the future our licensees or royalty-agreement counterparties or their licensees, which could cause delays or elimination of our receipts of potential milestones and royalties under our licensing or royalty and milestone acquisition arrangements.

In March 2020, COVID-19, the disease caused by a novel strain of coronavirus, was declared a pandemic by the World Health Organization. The pandemic has severely affected global economic activity and resulted in the implementation of significant governmental measures, including lockdowns, closures, quarantines and travel bans, intended to control the spread of the virus.

The COVID-19 pandemic has adversely impacted and could materially and adversely impact in the future our licensees or royalty-agreement counterparties or their licensees, which could cause delays, suspensions or cancellations of their drug development efforts including, without limitation, their clinical trials, which would correspondingly delay, suspend or negate the timing of our potential receipts of milestones and royalties under our out-licensing or royalty acquisition agreements. The disruptions to our licensees or royalty purchase agreement counterparties or their licensees could include, without limitation:

delays or difficulties in recruiting and enrolling new patients in their clinical trials;
delays or difficulties in clinical site initiation, including difficulties in recruiting clinical site investigators and clinical site staff;
diversion of healthcare resources away from the conduct of clinical trials, including the diversion of hospitals serving as their clinical trial sites and hospital staff supporting the conduct of their clinical trials;
interruption of key clinical trial activities, such as clinical trial site monitoring, due to limitations on travel imposed or recommended by federal, state or local governments, employers and others;

16

Table of Contents

limitations in employee resources that would otherwise be focused on the conduct of their clinical trials, including because of sickness of employees or their families or the desire of employees to avoid contact with large groups of people;
interruption in global shipping that may affect the transport of clinical trial supplies and materials, such as the investigational drug product used in their clinical trials;
delays in receiving approval from the U.S. Food and Drug Administration (“FDA”), the European Medicines Agency (“EMA”) and other U.S. and foreign federal, state and local regulatory authorities to initiate their planned clinical trials or to market their products;
changes in FDA, state and local regulation (and those of their foreign counterparts if applicable) as part of a response to the COVID-19 pandemic which may change the ways in which clinical trials are conducted or discontinue clinical trials altogether;
delays in necessary interactions with regulators, ethics committees and other important agencies and contractors due to limitations in employee resources or forced furlough of government employees;
delay in the timing of other interactions with the FDA due to absenteeism by federal employees or by the diversion of their efforts and attention to approval of other therapeutics or other activities related to COVID-19; and
refusal of the FDA to accept data from clinical trials in affected geographies outside the United States or of foreign regulatory authorities to accept data from clinical trials in affected areas outside their applicable countries.

The extent to which the COVID-19 pandemic continues to impact our business and prospects and the overall economies of the United States and other countries will depend on numerous evolving factors, which are highly uncertain and cannot be predicted with confidence, such as the duration and scope of the pandemic, potential mutations in the COVID-19 virus, travel restrictions and social distancing in the United States and other countries, business closures or business disruptions and the effectiveness of actions taken in the United States and other countries to contain and treat the disease.

The COVID-19 pandemic continues to pose risks to our business, including at our headquarters in Emeryville, California, which has in the past been subject to local and statewide “stay-at-home” orders issued by Alameda County and the Governor of the State of California, as well as the business or operations of our partners and other third parties with whom we conduct business.

The COVID-19 pandemic has resulted in extended travel and other continued restrictions in order to reduce the spread of the disease, including California executive orders, San Francisco Bay Area orders and several other state and local orders across the United States, which, among other things, direct individuals to continue to shelter at their places of residence, direct businesses and governmental agencies to cease non-essential operations at physical locations, prohibit certain non-essential gatherings, and order cessation of non-essential travel. The evolving effects of the COVID-19 pandemic and restrictive government measures taken in response have had a significant impact, both direct and indirect, on businesses and commerce, as significant reductions in business related activities have occurred, supply chains have been disrupted, and manufacturing and clinical development activities have been curtailed or suspended.

In response to these public health directives and orders, we previously implemented a work-from-home policy for all employees. We have been able to maintain our operations and productivity thus far; however, prolonged working remotely may negatively impact productivity, disrupt our business and delay our timelines, the magnitude of which will depend, in part, on the length and severity of the restrictions and other limitations on our ability to conduct our business in the ordinary course.

In addition, quarantines, stay-at-home, executive and similar government orders, shutdowns or other restrictions on the conduct of business operations continue to impact personnel at third-party clinical testing sites, manufacturing facilities, and the availability or cost of materials, which could disrupt our licensees’ and royalty purchase agreement counterparties and their licensees’ supply chains.

The spread of COVID-19, which has caused a broad impact globally, may materially affect us economically. While the evolving economic impacts brought by, and the duration of, COVID-19 may be difficult to assess or predict, it has already significantly disrupted global financial markets, and may limit our ability to access capital, which could in the future negatively affect our liquidity. A recession or market correction resulting from the spread of COVID-19 could materially affect our business and the value of our common stock.

The evolving effects of the COVID-19 pandemic have already resulted in significant disruption of global financial markets. While several of our partners have experienced delays due to the COVID-19 pandemic, we do not yet know the full extent of potential delays or impacts on our business, clinical trials, healthcare systems or the global economy as a whole. However, the effects could continue to have an impact on our operations and could have a material adverse effect on our business, financial condition, results of operations and prospects in future periods.

Our acquisitions of potential future royalty and/or milestone payments may not produce anticipated revenues and/or may be negatively affected by a default or bankruptcy of the licensor(s) or licensee(s) under the applicable license agreement(s) covering such potential royalties and/or milestones, and if such transactions are secured by collateral, we may be, or may become, under-secured by the collateral or such collateral may lose value and we will not be able to recuperate our capital expenditures associated with the acquisition.

We are engaged in a continual review of opportunities to acquire future royalties, milestones and other payments related to drug development and sales as part of our royalty aggregator strategy or to acquire companies that hold royalty assets. Generally, at any time, we seek to have acquisition opportunities in various stages of active review, including, for example, our engagement of consultants and advisors to analyze particular opportunities, technical, financial and other confidential information, submission of indications of interest and involvement as a bidder in competitive auctions. Many potential acquisition targets do not meet our criteria, and for those that do, we may face significant competition for these acquisitions from other royalty buyers and enterprises. Competition for future asset acquisition opportunities in our markets could increase the price we pay for such assets and could reduce the number of potential acquisition targets. The success of our acquisitions is based on our ability to make accurate assumptions regarding the valuation, probability, timing and amount of potential future royalty and milestone payments as well as the viability of the underlying technology and intellectual property. The failure of any of these acquisitions to produce anticipated revenues may materially and adversely affect our financial condition and results of operations.

Some of these acquisitions may expose us to credit risk in the event of a default by or bankruptcy of the licensor(s) or licensee(s) that are parties to the applicable license agreement(s) covering the potential milestone and royalty streams being acquired. In addition, the impact of COVID-19 on the capital markets may limit our licensees or royalty-agreement counterparties’ ability to access additional funding. While we generally try to structure our receipt of potential milestone and royalty payments to minimize the risk associated with such a default or bankruptcy, there can be no assurance that any such default or bankruptcy will not adversely affect our ability to receive future potential royalty and/or milestone payments. To mitigate this risk, on occasion, we may obtain a security interest as collateral in such royalty, milestone and other payments. Our credit risk in respect of such counterparty may be exacerbated when the collateral held by us cannot be realized upon or is liquidated at prices not sufficient to recover the full amount we are due pursuant to the terms of the agreements covering the particular assets. This could occur in circumstances where the original collateral was not sufficient to cover a complete loss (e.g., our interests were only partially secured) or may result from the deterioration in value of the collateral, so that, in either such case, we are unable to recuperate our full capital outlay. Any such losses resulting therefrom could materially and adversely affect our financial condition and results of operations.

Many of our potential royalty acquisitions may be associated with drug products that are in clinical development and have not yet been commercialized. To the extent that such products are not successfully developed and commercialized, our financial condition and results of operations may be negatively impacted. Acquisitions of potential royalties associated with development stage biopharmaceutical product candidates are subject to a number of uncertainties.

As part of our royalty aggregator strategy, we may continue to purchase future potential milestone and royalty streams associated with drug products which are in clinical development and have not yet received marketing approval by any regulatory authority or been commercialized. There can be no assurance that the FDA, the EMA or other regulatory authorities will approve such products or that such products will be brought to market timely or at all, or that the market will be receptive to such products. To the extent that any such drug products are not successfully developed and subsequently commercialized, the value of our acquired potential milestone and royalty streams will be negatively affected. The ultimate success of our royalty aggregator strategy will depend on our ability to properly identify and acquire high quality products and the ability of the applicable counterparty to innovate, develop and commercialize their products, in increasingly competitive and highly regulated markets. Their inability to do so would negatively affect our ability to receive royalty and/or milestone payments. In addition, we are dependent, to a large extent, on third parties to enforce certain rights for our benefit, such as protection of a patent estate, adequate reporting and other protections, and their failure to do so would presumably negatively impact our financial condition and results of operations.

If the FDA, the EMA or other regulatory authority approves a development-stage product candidate that generates our royalty, the labeling, packaging, adverse event reporting, storage, advertising, promotion and recordkeeping for the product will be subject to extensive and ongoing regulatory requirements. The subsequent discovery of previously unknown problems with the product, including adverse events of unanticipated severity or frequency, may result in restrictions on the marketing of the product, and could include withdrawal of the product from the market.

In addition, the developers of these development-stage product candidates may not be able to raise additional capital to continue their discovery, development and commercialization activities, which may cause them to delay, reduce the scope of, or eliminate one or more of their clinical trials or research and development programs. If other product developers introduce and market products that are more effective, safer, less invasive or less expensive than the relevant products that generate our royalties, or if such developers introduce their products prior to the competing products underlying our royalties, such products may not achieve commercial success and thereby result in a loss for us.

Further, the developers of such products may not have sales, marketing or distribution capabilities. If no sales, marketing or distribution arrangements can be made on acceptable terms or at all, the affected product may not be able to be successfully commercialized, which will result in a loss for us. Losses from such assets could have a material adverse effect on our business, financial condition and results of operations.

We intend to continue, and may increase, this strategy of acquiring development-stage product candidates. While we believe that we can readily evaluate and gain conviction about the likelihood of a development-stage product candidate’s approval and achieving significant sales, there can be no assurance that our assumptions will prove correct, that regulatory authorities will approve such development-stage product candidates, that such development-stage product candidates will be brought to market timely or at all, or that such products will achieve commercial success.

We have significantly restructured our business and revised our business plan and there are no assurances that we will be able to successfully implement our revised business plan or successfully operate as a royalty aggregator.

We have historically been focused on discovering and developing innovative therapeutics derived from our unique platform of antibody technologies. We have now become a royalty aggregator where we focus on expanding our pipeline of fully-funded programs by out-licensing our internally developed product candidates and acquiring potential milestone and royalty revenue streams on additional third party drug product candidates. Our strategy is based on a number of factors and assumptions, some of which are not within our control, such as the actions of third parties. There can be no assurance that we will be able to successfully execute all or any elements of our strategy, or that our ability to successfully execute our strategy will be unaffected by external factors. If we are unsuccessful in acquiring potential milestone and royalty revenue streams on additional drug product candidates, or those acquisitions do not perform to our expectations, our financial performance and balance sheet could be adversely affected.

Risks Related to our Industry

Biopharmaceutical products are subject to sales risks.

Biopharmaceutical product sales may be lower than expected due to a number of reasons, including pricing pressures, insufficient demand, product competition, failure of clinical trials, lack of market acceptance, obsolescence, loss of patent protection, the impact of the COVID-19 global pandemic or other factors, and development-stage product candidates may fail to reach the market. Unexpected side effects, safety or efficacy concerns can arise with respect to a product, leading to product recalls, withdrawals or declining sales. As a result, payments of our future potential milestones and/or royalties may be reduced or cease. In addition, these potential payments may be delayed, causing our near-term financial performance to be weaker than expected.

Biopharmaceutical products are subject to substantial competition.

The biopharmaceutical industry is a highly competitive and rapidly evolving industry. The length of any product’s commercial life cannot be predicted with certainty. There can be no assurance that one or more products on which we are entitled to a potential milestone or royalty will not be rendered obsolete or non-competitive by new products or improvements on which we are not entitled to a potential milestone or royalty, either by the current marketer of such products or by another marketer. Current marketers of products may undertake these development efforts in order to improve their products or to avoid paying our royalty. Adverse competition, obsolescence or governmental and regulatory action or healthcare policy changes could significantly affect the revenues, including royalty-related revenues, of the products which generate our potential milestones and royalties.

Competitive factors affecting the market position and success of each product include: 

effectiveness;
safety and side effect profile;
price, including third-party insurance reimbursement policies;
timing and introduction of the product;
effectiveness of marketing strategy and execution;
governmental regulation;
availability of lower-cost generics and/or biosimilars;
treatment innovations that eliminate or minimize the need for a product; and
product liability claims.

Biopharmaceutical products that have the potential to generate future milestones and royalties for us may be rendered obsolete or non-competitive by new products, including generics and/or biosimilars, improvements on existing products or governmental or regulatory action. In addition, as biopharmaceutical companies increasingly devote significant resources to innovate next-generation products and therapies using gene editing and new curative modalities, such as cell and gene therapy, products on which we have a milestone or royalty rights may become obsolete. These developments could have a material adverse effect on the sales of the biopharmaceutical products that have potential to generate our milestones and royalties, and consequently could materially adversely affect our business, financial condition and results of operations.

We depend on our licensees and royalty-agreement counterparties for the determination of royalty and milestone payments. While we typically have primary or back-up rights to audit our licensees and royalty-agreement counterparties, the independent auditors may have difficulty determining the correct royalty calculation, we may not be able to detect errors and payment calculations may call for retroactive adjustments. We may have to exercise legal remedies, if available, to resolve any disputes resulting from any such audit.

The royalty and milestone payments we may receive are dependent on our licensees and royalty agreement counterparties and their licensees’ achievement of regulatory and developmental milestones and product sales. Each licensee’s calculation of the royalty payments is subject to and dependent upon the adequacy and accuracy of its sales and accounting functions, and errors may occur from time to time in the calculations made by a licensee and/or a licensee may fail to report the achievement of royalties or milestones in whole or in part. Our license and royalty agreements typically provide us the primary or back-up right to audit the calculations and sales data for the associated royalty payments; however, such audits may occur many months following our recognition of the royalty revenue, may require us to adjust our royalty revenues in later periods and may require expense on our part. Further, our licensees and royalty-agreement counterparties may be uncooperative or have insufficient records, which may complicate and delay the audit process.

Although we intend to regularly exercise our royalty audit rights as necessary and to the extent available, we rely in the first instance on our licensees and royalty-agreement counterparties to accurately report the achievement of milestones and royalty sales and calculate and pay applicable milestones and royalties and, upon exercise of such royalty and other audit rights, we rely on licensees’ and royalty-agreement counterparties’ cooperation in performing such audits. In the absence of such cooperation, we may be forced to incur expenses to exercise legal remedies, if available, to enforce our agreements.

The lack of liquidity of our acquisitions of future potential milestones and royalties may adversely affect our business and, if we need to sell any of our acquired assets, we may not be able to do so at a favorable price, if at all. As a result, we may suffer losses.

We generally acquire milestone and royalty rights that have limited secondary resale markets and may be subject to transfer restrictions. The illiquidity of most of our milestone and royalty receivable assets may make it difficult for us to dispose of them at a favorable price if at all and, as a result, we may suffer losses if we are required to dispose of any or all such assets in a forced liquidation or otherwise. In addition, if we liquidate all or a portion of our potential future milestone and/or purchased royalty stream interests quickly or relating to a forced liquidation, we may realize significantly less than the value at which we had previously recorded these interests.

Our royalty aggregator strategy may require that we register with the SEC as an “investment company” in accordance with the Investment Company Act of 1940.

The rules and interpretations of the SEC and the courts, relating to the definition of "investment company" are very complex. While we currently intend to conduct our operations so that we will not be an investment company under applicable SEC interpretations, we can provide no assurance that the SEC would not take the position that the Company would be required to register under the Investment Company Act of 1940 (the “‘40 Act”) and comply with the ‘40 Act’s registration and reporting requirements, capital structure requirements, affiliate transaction restrictions, conflict of interest rules, requirements for disinterested directors, and other substantive provisions. We monitor our assets and income for compliance under the ‘40 Act and seek to conduct our business activities to ensure that we do not fall within its definitions of “investment company,” or that we qualify under one of the exemptions or exclusions provided by the ‘40 Act and corresponding SEC regulations. If we were to become an “investment company” and be subject to the restrictions of the ‘40 Act, those restrictions would likely require significant changes in the way we do business and add significant administrative burdens to our operations. To ensure that we do not fall within the ‘40 Act, we may need to take various actions which we might otherwise not pursue. These actions may include restructuring the Company and/or modifying our mixture of assets and income or a liquidation of certain of our assets.

Our licensees or royalty-agreement counterparties or their licensees could be subject to natural disasters, public health crises, political crises and other catastrophic events that could hinder or disrupt development efforts.

We depend on our licensees and royalty-agreement counterparties and their licensees to successfully develop and commercialize product candidates for which we may receive milestone and royalty payments in the future. Our licensees and royalty-agreement counterparties and their licensees operate research and development efforts in various locations in the United States and internationally. If any of their facilities is affected by natural disasters, such as earthquakes, tsunamis, power shortages or outages, floods or monsoons, public health crises, such as pandemics and epidemics, political crises, such as terrorism, war, political instability or other conflict, or other events outside of their control, their research and development efforts could be disrupted, which could result in the delay or discontinuation of development of one or more of the product candidates in which we have rights to future milestone and/or royalty payments which could have a material adverse effect on our business operations and prospects.

Because many of the companies with which we do business also are in the biotechnology sector, the volatility of that sector can affect us indirectly as well as directly.

The same factors that affect us directly also can adversely affect us indirectly by affecting the ability of our partners and others with whom we do business to meet their obligations to us and reduce our ability to realize the value of the consideration provided to us by these other companies in connection with their licensing of our products.

Risks Related to our Financial Results and Capital Requirements

We have sustained losses in the past, and we expect to sustain losses in the foreseeable future.

We have incurred significant operating losses and negative cash flows from operations since our inception. Although, we generated net income of $13.3 million and positive cash flows from operations of $10.1 million for the year ended December 31, 2020, we had net losses of $2.0 million for the year ended December 31, 2019. As of December 31, 2020, we had an accumulated deficit of $1.2 billion. We do not know whether we will ever achieve sustained profitability or whether cash flow from future operations will be sufficient to meet our needs.

To date, we have financed our operations primarily through the sale of equity securities and debt and royalty interests, and payments received under our collaboration and licensing arrangements. The size of our future net losses will depend, in part, on the rate of our future expenditures and our and our partners’ ability to generate revenues. If our partners’ product candidates are not successfully developed or commercialized, or if revenues are insufficient following regulatory approval, we will not achieve profitability and our business may fail. Our ability to achieve profitability is dependent in large part on the success of our and our partners’ ability to license product candidates, and the success of our partners’ development programs, both of which are uncertain. Our success is also dependent on our partners obtaining regulatory approval to market product candidates which may not materialize or prove to be successful.

Our royalty aggregator strategy may require us to raise additional funds to acquire milestone and royalty interests; we cannot be certain that funds will be available or available at an acceptable cost of capital, and if they are not available, we may be unsuccessful in acquiring milestone and royalty interests to sustain the business in the future.

We may need to commit substantial funds to continue our business, and we may not be able to obtain sufficient funds on acceptable terms, if at all. Any additional debt financing or additional equity that we raise may contain terms that are not favorable to us and/or result in dilution to our stockholders, including pursuant to our 2018 ATM Agreement, as amended. Our Series A Preferred Stock, while not dilutive, includes dividends and required that we establish a segregated cash account adequate to fund the dividends. If we raise additional funds through licensing arrangements with third parties, we may be required to relinquish some rights to our technologies or our product candidates, grant licenses on terms that are not favorable to us or enter into a license arrangement for a product candidate at an earlier stage of development or for a lesser amount than we might otherwise choose.

Table of Contents

If adequate funds are not available on a timely basis, we may:

reduce or eliminate royalty aggregation efforts;
further reduce our capital or operating expenditures;
curtail our spending on protecting our intellectual property; or
take other actions which may adversely affect our financial condition or results of operations.

Changes in the potential royalty acquisition market, including its structure and participants, or a reduction in the growth of the biopharmaceutical industry, could lead to diminished opportunities for us to acquire potential milestones and royalties, fewer potential milestones and royalties (or potential milestones or royalties of significant scale) being available, or increased competition for potential royalties. Even if we continue to acquire potential royalties and they become actual royalties, they may not generate a meaningful return for a period of several years, if at all, due to the price we pay for such royalties or other factors relating to the underlying products. As a result, we may not be able to continue to acquire potential milestones and royalties as we have in the past, or at all.

We use leverage in connection with our capital deployment, which magnifies the potential for loss if the potential royalties acquired or generated through out-licensing and royalty purchase agreements do not generate sufficient income to us.

We use borrowed funds to finance a portion of our deployed capital. The use of leverage creates an opportunity for an increased return but also increases the risk of loss if our assets do not generate sufficient income to us. The interest expense and other costs incurred in connection with such borrowings may not be covered by the future potential income from our assets. In addition, leverage and the requirement to pay cumulative dividends on Series A Preferred Stock, may inhibit our operating flexibility and reduce cash flow available for dividends to our common shareholders.

The level of our indebtedness could limit our ability to respond to changing business conditions. The various agreements relating to our borrowings may impose operating and financial restrictions on us which could affect the number and size of the potential milestones and royalties that we may pursue. Therefore, no assurance can be given that we will be able to take advantage of favorable conditions or opportunities as a result of any restrictive covenants under our indebtedness or preferred stock. There can also be no assurance that additional debt or equity financing, either to replace or increase existing debt financing, will be available when needed or, if available, will be obtainable on terms that are commercially reasonable.

Additional risks related to our leverage include:

our potential future milestones and royalties are used as collateral for our borrowings;
in the event of a default under any of our secured borrowings, one or more of our creditors or their assignees could obtain control of our future potential milestones and royalties and, in the event of a distressed sale, these creditors could dispose of these royalties for significantly less value than we could realize for them;
we may have to comply with various financial covenants in future agreements that govern our debt, including requirements to maintain certain leverage ratios and coverage ratios, which may affect our ability to achieve our business objectives;
our ability to pay dividends to our shareholders (except with respect to our Series A preferred stock) may be restricted;
to the extent that interest rates at which we borrow increase, our borrowing costs will increase, and our leveraging strategy will become more costly, which could lead to diminished net profits; and

We have a continuing obligation to pay quarterly dividends to holders of our Series A Preferred stock, which will be an on-going expenditure for us and may limit our ability to borrow additional funds.

Holders of our Series A preferred stock are entitled to receive, when and as declared by our Board of Directors, out of funds legally available for the payment of dividends, cumulative cash dividends at the rate of 8.625% of the $25.00 liquidation preference per year (equivalent to $2.15625 per year). Dividends on the Series A preferred stock will accumulate and be cumulative from, and including, the date of original issue by us of the Series A preferred stock. Dividends will be payable in arrears on or about the 15th day of January, April, July and October beginning on or about April 15, 2021. In the event of any voluntary or involuntary liquidation, dissolution or winding up of our affairs, the holders of shares of Series A preferred stock are entitled to be paid out of our assets legally available for distribution to our shareholders a liquidation preference of $25.00 per share, plus an amount equal to any accumulated and unpaid dividends up to the date of payment (whether or not declared), before any distribution or payment may be made to holders of shares of common stock or any other class or series of our equity stock ranking, as to liquidation rights, junior to the Series A preferred stock. On and after December 15, 2021, the shares of Series A preferred stock will be redeemable at our option, in whole or in part, at redemption prices ranging from $26.00 per share to $25.00 per share, plus any accrued and unpaid dividends, depending on the date of redemption. The payment of cash dividends and share repurchases is subject to limitations under applicable laws and the discretion of our Board of Directors and is determined after considering current conditions, including earnings, other operating results and capital requirements. Decreases in asset values or increases in liabilities can reduce net earnings and stockholders’ equity. A deficit in stockholders’ equity could limit our ability to pay dividends and make share repurchases under Delaware law. On the other hand, our continued obligation to pay dividends to the holders of our Series A preferred stock could restrict us from additional borrowings or make them more costly.

The holders of our indebtedness and preferred stock have rights that are senior to those of our common stockholders.

As of December 31, 2020, the outstanding principal balance of our indebtedness under the Loan Agreement was $12.2 million. The indebtedness under the Loan Agreement is senior to our shares of preferred stock and common stock in right of payment of dividends and other distributions. In the event of our bankruptcy, dissolution or liquidation, the holders of our indebtedness must be satisfied before any distributions can be made to our preferred or common stockholders.

At December 31, 2020 we had issued and outstanding 984,000 shares of Series A Preferred Stock with a liquidation preference of $25.00 per share, plus an amount equal to any accumulated and unpaid dividends up to the date of payment (whether or not declared). Our preferred stock is senior to our shares of common stock in right of payment of dividends and other distributions. In the event of our bankruptcy, dissolution or liquidation, the holders of our preferred stock must be satisfied before any distributions can be made to our common stockholders.

Information available to us about the biopharmaceutical products underlying the potential royalties we buy may be limited and therefore our ability to analyze each product and its potential future cash flow may be similarly limited.

We may have limited information concerning the products generating the future potential milestones and royalties we are evaluating for acquisition. Often, the information we have regarding products following our acquisition of a potential milestone or royalty may be limited to the information that is available in the public domain. Therefore, there may be material information that relates to such products that we would like to know but do not have and may not be able to obtain. For example, we do not always know the results of studies conducted by marketers of the products of others or the nature or amount of any complaints from doctors or users of such products. In addition, the market data that we obtain independently may also prove to be incomplete or incorrect. Due to these and other factors, the actual potential cash flow from a potential royalty may be significantly lower than our estimates.

Our future income is dependent upon numerous potential milestone and royalty-specific assumptions and, if these assumptions prove not to be accurate, we may not achieve our expected rates of returns.

Our business model is based on multiple-year internal and external forecasts regarding potential product sales and numerous product-specific assumptions in connection with each potential milestone and royalty acquisition, including where we have limited information regarding the product. There can be no assurance that the assumptions underlying our financial models, including those regarding potential product sales or competition, patent expirations or license

24

Table of Contents

terminations for the products underlying our portfolio, are accurate. These assumptions involve a significant element of subjective judgment and may be and in the past have been adversely affected by post-acquisition changes in market conditions and other factors affecting the underlying product. Our assumptions regarding the financial stability or operational or marketing capabilities of the partner obligated to pay us potential royalties may also prove to be incorrect. Due to these and other factors, the assets in our current portfolio or future assets may not generate our projected returns or in the time periods we expect. This could negatively impact our results of operation for a given period.

Reductions or declines in income from potential milestones and royalties, or significant reductions in potential milestone or royalty payments compared to expectations, or impairments in the value of potential milestones and royalties acquired could have a material adverse effect our financial condition and results of operations.

The amount and duration of a royalty usually varies on a country-by-country basis and can be based on a number of factors, such as payments to third party licensors, whether the product is sold singly or in combination, patent expiration dates, regulatory exclusivity, years from first commercial sale of the applicable drug product, the entry of competing generic or biosimilar products, or other terms set out in the contracts governing the royalty. It is common for royalty durations to expire earlier or later than anticipated due to unforeseen positive or negative developments over time, including with respect to the granting of patents and patent term extensions, the invalidation of patents, claims of patent misuse, litigation between the party controlling the patents and third party challengers of the patents, the ability of third parties to design around or circumvent valid patents, the granting of regulatory exclusivity periods or extensions, timing for the arrival of generic or biosimilar competitor products, changes to legal or regulatory regimes affecting intellectual property rights or the regulation of pharmaceutical products, product life cycles, and industry consolidations. If an unexpected reduction in a royalty amount or shortening of a potential royalty term were to occur, it could result in a reduction in potential income from milestones and royalties, a significant reduction in potential milestones and royalty payments compared to expectations, or a permanent impairment of such potential milestones and royalty payments.

A large percentage of the calculated net present value of our portfolio is represented by a limited number of products. The failure of any one of these products to move forward in clinical development or commercialization may have a material adverse effect on our financial condition and results of operation.

Our asset portfolio may not be fully diversified by product, therapeutic area, geographic region or other criteria. Any significant deterioration in the amount or likelihood of receipt of potential cash flows from the top products in our asset portfolio could have a material adverse effect on our business, financial condition and results of operations. In addition, should the payor of any future potential milestones or royalties decline to pay such potential milestones and royalties for any reason, such failure may result in a material adverse effect on our financial condition and results of operation.

Risks Related to Our Reliance on Third Parties

We and our partners rely heavily on license and collaboration relationships, and any disputes or litigation with our partners or termination or breach of any of the related agreements could reduce the financial resources available to us, including our ability to receive milestone payments and future potential royalty and other revenues. License or collaboration agreements relating to products may, in some instances, be unilaterally terminated or disputes may arise which may affect our potential milestones, royalties and other payments.

License or collaboration agreements relating to the products generating our future potential milestones and royalties and other payment rights may be terminated, which may adversely affect sales of such products and therefore the potential payments we may receive. For example, under certain license or collaboration agreements, marketers may retain the right to unilaterally terminate the agreements. When the last patent covering a product expires or is otherwise invalidated in a country, a marketer may be economically motivated to terminate the applicable license or collaboration agreement, either in whole or with respect to such country, in order to terminate its payment and other obligations. In the event of such a termination, a licensor (which may be us in the case of our out-licensed products) or collaborator may no longer receive all of the payments it expected to receive from the applicable licensee or collaborator and may also be unable to find another company to continue developing and commercializing the product on the same or similar terms as those under the license or collaboration agreement that has been terminated.

25

Table of Contents

In addition, license or collaboration agreements may fail to provide significant protection for the applicable licensor (which may be us in the case of our out-licensed products) or collaborator in case of the applicable licensee’s or collaborator’s failure to perform or in the event of disputes. License and collaboration agreements which relate to the products underlying our potential future milestones, royalties and other payment rights, are complex and certain provisions in such agreements may be susceptible to multiple interpretations. Disputes may arise regarding intellectual property, royalty terms, payment rights or other contractual terms subject to a license or collaboration agreement, including:

the scope or duration of rights granted under the license or collaboration agreement and other interpretative issues;
the amounts or timing of royalties, milestones or other payments due under the license or collaboration agreement;
the sublicensing of patent or other rights under our license or collaboration relationships;
the diligence obligations under the license or collaboration agreement and what activities satisfy such diligence obligations:
the inventorship and ownership of inventions and know-how resulting from the joint creation or use of intellectual property by us or our partners; and
the priority of invention of patented technology.

The resolution of any contract interpretation disagreement that may arise could narrow what the licensor (which may be us in the case of our out-licensed products) or collaborator believes to be the scope of its rights to the relevant intellectual property or technology, or decrease the licensee’s or collaborator’s financial or other obligations under the relevant agreement, any of which could in turn impact the value of our potential royalties, milestones and other payments and have a material adverse effect on our business, financial condition, results of operations and prospects. If a marketer were to default on its obligations under a license or collaboration agreement, the licensor’s or collaborator’s remedy may be limited either to terminating certain licenses or collaborations related to certain countries or to generally terminate the license or collaboration agreement with respect to such country. In such cases, we may not have the right to seek to enforce the rights of the licensor or collaborator (if not us) and we may be required to rely on the resources and willingness of the licensor or collaborator (if not us) to enforce its rights against the applicable licensee or collaborator. In any of these situations, if the expected upfront, milestone, royalty or other payments under the license or collaboration agreements do not materialize, this could result in a significant loss to us and materially adversely affect our business, financial condition and results of operations. At any given time, the Company may be engaged in discussions with its licensees or collaborators regarding the interpretation of the payment and other provisions relating to products as to which we have milestones and potential royalty or other payment rights. Should any such discussions result in a disagreement regarding a particular product that cannot be resolved satisfactorily to us, we may end up being paid less than anticipated on such product should it successfully progress through clinical development and be approved for commercialization. Should our milestone and future potential royalty or other payment interests be reduced or eliminated as result of any such disagreement, it could have an adverse effect on our business, financial condition, results of operation and prospects.

Our existing collaborations may not continue or be successful, and we may be unable to enter into future collaborative arrangements to develop and commercialize our unpartnered assets. Generally, our current collaborative partners also have the right to terminate their collaborations at will or under specified circumstances. If any of our collaborative partners breach or terminate their agreements with us or otherwise fail to conduct their collaborative activities successfully (for example, by not making required payments when due, or at all or failing to engage in commercially reasonable efforts to develop products if required), our product development under these agreements will be delayed or terminated.

Our potential milestone and royalty providers may rely on third parties to provide services in connection with their product candidate development and manufacturing programs. The inadequate performance by or loss of any of these service providers could affect our potential milestone and royalty providers’ product candidate development.

Third parties provide services in connection with preclinical and clinical development programs, including in vitro and in vivo studies, assay and reagent development, immunohistochemistry, toxicology, pharmacokinetics, clinical trial support, manufacturing and other outsourced activities. If these service providers do not adequately perform the services for which our potential milestone and royalty providers have contracted, or cease to continue operations, and are not able to find a replacement provider quickly or lose information or items associated with their drug product candidates, our potential milestone and royalty providers’ development programs and receipt of any potential resulting income may be delayed.

Agreements with other third parties, many of which are significant to our business, expose us to numerous risks.

Because our licensees, suppliers and contractors are independent third parties, they may be subject to different risks than we are and have significant discretion in, and different criteria for, determining the efforts and resources they will apply related to their agreements with us. If these licensees, suppliers and contractors do not successfully perform the functions for which they are responsible, we may not have the capabilities, resources or rights to do so on our own.

We do not know whether we or our licensees will successfully develop and market any of the products that are or may become the subject of any of our licensing arrangements. In addition, third-party arrangements such as ours also increase uncertainties in the related decision-making processes and resulting progress under the arrangements, as we and our licensees may reach different conclusions, or support different paths forward, based on the same information, particularly when large amounts of technical data are involved.

Under our contracts with NIAID, a part of the National Institute of Health (“NIH”), we invoiced using NIH provisional rates, and these are subject to future audits at the discretion of NIAID’s contracting office. In October of 2019, NIH notified us that it engaged KPMG LLP (“KPMG”) to perform an audit of our Incurred Cost Submissions for 2013, 2014 and 2015. The audit procedures were complete as of December 31, 2020 and we adjusted our estimated liability owed to NIH to $1.4 million. This audit has resulted in an adjustment to revenue previously reported. The audit remains subject to further review by NIH as part of the contract close-out process and we may incur further liability as a result.  

In addition, under the contracts with HCRP, the amortization for the reporting period is calculated based on the payments expected to be made by the licensees to HCRP over the term of the arrangement. Any changes to the estimated payments by the licensees to HCRP can result in a material adjustment to revenue previously reported.

Failure of our potential milestone and royalty providers’ product candidates to meet current Good Manufacturing Practices standards may subject our licensees to delays in regulatory approval and penalties for noncompliance.

Our potential milestone and royalty providers may rely on third party manufacturers and such contract manufacturers are required to produce clinical product candidates under current Good Manufacturing Practices (“cGMP”) to meet acceptable standards for use in clinical trials and for commercial sale, as applicable. If such standards change, the ability of contract manufacturers to produce our potential milestone and royalty providers’ drug product candidates on the schedule required for clinical trials or to meet commercial requirements may be affected. In addition, contract manufacturers may not perform their obligations under their agreements with our potential milestone and royalty providers or may discontinue their business before the time required by us to successfully produce clinical and commercial supplies of our potential milestone and royalty providers’ product candidates.

Contract manufacturers are subject to pre-approval inspections and periodic unannounced inspections by the FDA and corresponding state and foreign authorities to ensure strict compliance with cGMP and other applicable government regulations and corresponding foreign standards. We do not have control over a third-party manufacturer’s compliance with these regulations and standards. Any difficulties or delays in contractors’ manufacturing and supply of our potential milestone and royalty providers’ product candidates or any failure of our potential milestone and royalty providers’ contractors to maintain compliance with the applicable regulations and standards could increase costs, reduce revenue,

27

Table of Contents

make our licensees postpone or cancel clinical trials, prevent or delay regulatory approval by the FDA and corresponding state and foreign authorities, prevent the import and/or export of our potential milestone and royalty providers’ product candidates, or cause any of our potential milestone and royalty providers’ products that may be approved for commercial sale to be recalled or withdrawn.

Certain of our technologies are in-licensed from third parties, so our and our licensees’ capabilities use of them may be restricted and subject to additional risks.

We have licensed technologies from third parties. These technologies include phage display technologies licensed to us in connection with our bacterial cell expression technology licensing program and antibody products. However, our and our licensees and collaborators’ use of these technologies is limited by certain contractual provisions in the licenses relating to them, and although we have obtained numerous licenses, intellectual property rights in the area of phage display are particularly complex. If we are unable to maintain our licenses, patents or other intellectual property, we could lose important protections that are material to continuing our operations and for future prospects. Our licensors also may seek to terminate our license, which could cause us and our licensees to lose the right to use the licensed intellectual property and adversely affect our and our licensees’ ability to commercialize our technologies, products or services.

Risks Related to the Development and Commercialization of our Current and Future Product Candidates

We may not be able to successfully identify and acquire potential milestone and royalty streams on other products, product candidates, or programs, or other companies to grow and diversify our business, and, even if we are able to do so, we may not be able to successfully manage the risks associated with integrating any such products, product candidates, programs or companies into our business or we may otherwise fail to realize the anticipated benefits of these acquisitions.

To grow and diversify our business, we plan to continue our business development efforts to identify and seek to acquire and/or in-license potential milestone and royalty streams or companies. Future growth through acquisition or in-licensing will depend upon the availability of suitable products, product candidates, programs or companies for acquisition or in-licensing on acceptable prices, terms and conditions. Even if appropriate opportunities are available, we may not be able to acquire rights to them on acceptable terms, or at all. The competition to acquire or in-license rights to promising products, product candidates, programs and companies is fierce, and many of our competitors are large, multinational pharmaceutical and biotechnology companies with considerably more financial, development and commercialization resources, personnel, and experience than we have. In order to compete successfully in the current business climate, we may have to pay higher prices for assets than may have been paid historically, which may make it more difficult for us to realize an adequate return on any acquisition.

Even if we are able to successfully identify and acquire or in-license new products, product candidates, programs or companies, we may not be able to successfully manage the risks associated with integrating any products, product candidates, programs or companies into our business or the risks arising from anticipated and unanticipated problems in connection with an acquisition or in-licensing. Further, while we seek to mitigate risks and liabilities of potential acquisitions through, among other things, due diligence, there may be risks and liabilities that such due diligence efforts fail to discover, that are not disclosed to us, or that we inadequately assess. Any failure in identifying and managing these risks and uncertainties effectively would have a material adverse effect on our business. In any event, we may not be able to realize the anticipated benefits of any acquisition or in-licensing for a variety of reasons, including the possibility that a product candidate fails to advance to clinical development, proves not to be safe or effective in clinical trials, or that a product fails to reach its forecasted commercial potential or that the integration of a product, product candidate, program or company gives rise to unforeseen difficulties and expenditures. Any failure in identifying and managing these risks and uncertainties would have a material adverse effect on our business.

If our potential royalty providers’ therapeutic product candidates do not receive regulatory approval, our potential royalty providers will be unable to market them.

Our potential royalty providers’ product candidates cannot be manufactured and marketed in the United States or any other countries without required regulatory approvals. The U.S. government and governments of other countries extensively regulate many aspects of our product candidates, including:

clinical development and testing;
manufacturing;
labeling;
storage;
record keeping;
promotion and marketing; and
importing and exporting.

In the United States, the FDA regulates pharmaceutical products under the Federal Food, Drug, and Cosmetic Act and other laws, including, in the case of biologics, the Public Health Service Act.

Initiation of clinical trials requires approval by health authorities. Clinical trials involve the administration of the investigational new drug to healthy volunteers or to patients under the supervision of a qualified principal investigator. Clinical trials must be conducted in accordance with FDA and International Conference on Harmonization Good Clinical Practices and the European Clinical Trials Directive, as applicable, under protocols that detail the objectives of the study, the parameters to be used to monitor safety and the efficacy criteria to be evaluated. Other national, foreign and local regulations also may apply. The developer of the drug must provide information relating to the characterization and controls of the product before administration to the patients participating in the clinical trials. This requires developing approved assays of the product to test before administration to the patient and during the conduct of the trial. In addition, developers of pharmaceutical products must provide periodic data regarding clinical trials to the FDA and other health authorities, and these health authorities may issue a clinical hold upon a trial if they do not believe, or cannot confirm, that the trial can be conducted without unreasonable risk to the trial participants.

The results of the preclinical studies and clinical testing, together with chemistry, manufacturing and controls information, are submitted to the FDA and other health authorities in the form of a New Drug Application (“NDA”) for a drug, and in the form of a Biologic License Application (“BLA”) for a biological product, requesting approval to commence commercial sales. In responding to an NDA or BLA, the FDA or foreign health authorities may grant marketing approvals, request additional information or further research, or deny the application if they determine the application does not satisfy regulatory approval criteria. Regulatory approval of an NDA, BLA, or supplement is never guaranteed. The approval process can take several years, is extremely expensive and can vary substantially based upon the type, complexity, and novelty of the products involved, as well as the target indications. Our potential royalty providers ultimately may not be able to obtain approval in a timely fashion or at all.

The FDA and foreign health authorities have substantial discretion in the drug and biologics approval processes. Despite the time and expense incurred, failure can occur at any stage, and our potential development partners could encounter problems that cause abandonment of clinical trials or cause them to repeat or perform additional preclinical, clinical or manufacturing-related studies.

29

Table of Contents

Changes in the regulatory approval policy during the development period, changes in, or the enactment of additional regulations or statutes, or changes in regulatory review for a submitted product application may cause delays in the approval or rejection of an application.

The FDA and other regulatory agencies have substantial discretion in both the product approval process and manufacturing facility approval process, and as a result of this discretion and uncertainties about outcomes of testing, we cannot predict at what point, or whether, the FDA or other regulatory agencies will be satisfied with our licensees’ submissions or whether the FDA or other regulatory agencies will raise questions that may be material and delay or preclude product approval or manufacturing facility approval. In light of this discretion and the complexities of the scientific, medical and regulatory environment, our or our potential royalty providers’ interpretation or understanding of the FDA’s or other regulatory agencies’ requirements, guidelines or expectations may prove incorrect, which also could delay further or increase the cost of the approval process.

Our potential milestone and royalty providers face uncertain results of clinical trials of product candidates.

Drug development has inherent risk, and our potential milestone and royalty providers are required to demonstrate through adequate and well-controlled clinical trials that product candidates are effective, with a favorable benefit-risk profile for use in their target profiles before they can seek regulatory approvals for commercial use. It is possible our potential royalty providers may never receive regulatory approval for any licensed product candidates. Even if a product candidate receives regulatory approval, the resulting product may not gain market acceptance among physicians, patients, healthcare payors and the medical community.

Our potential milestone and royalty providers’ product candidates require significant additional research and development, extensive preclinical studies and clinical trials and regulatory approval prior to any commercial sales. This process is lengthy and expensive, often taking a number of years. As clinical results frequently are susceptible to varying interpretations that may delay, limit or prevent regulatory approvals, the length of time necessary to complete clinical trials and to submit an application for marketing approval for a final decision by a regulatory authority varies significantly. As a result, it is uncertain whether:

our potential milestone and royalty providers’ future filings will be delayed;
our potential milestone and royalty providers’ preclinical studies will be successful;
our potential milestone and royalty providers will be successful in generating viable product candidates;
we will be successful in finding collaboration and licensing partners to advance our product candidates on our behalf;
our potential milestone and royalty providers will be able to provide necessary data;
results of future clinical trials by our potential milestone and royalty providers will justify further development; or
our potential milestone and royalty providers ultimately will achieve regulatory approval for product candidates in which we have an interest.

The timing of the commencement, continuation and completion of clinical trials by our potential milestone and royalty providers may be subject to significant delays relating to various causes, including failure to complete preclinical testing and earlier-stage clinical trials in a timely manner, inability to engage contract research organizations and other service providers, scheduling conflicts with participating clinicians and clinical institutions, changes in key personnel at clinical institutions, difficulties in identifying and enrolling patients who meet trial eligibility criteria and shortages of available drug supply. In addition, since we and our royalty agreement counterparties license our product candidates to others to fund and conduct clinical trials, we, and they, have limited control over how quickly and efficiently such licensees

30

Table of Contents

advance those trials. Patient enrollment is a function of many factors, including the size of the patient population, the proximity of patients to clinical sites, the concentration of patients in specialist centers, the eligibility criteria for the trial, the existence of competing clinical trials and the availability of alternative or new treatments. Regardless of the initial size or relative complexity of a clinical trial, the costs of such trial may be higher than expected due to increases in duration or size of the trial, changes in the protocol under which the trial is being conducted, additional or special requirements of one or more of the healthcare centers where the trial is being conducted, or changes in the regulatory requirements applicable to the trial or in the standards or guidelines for approval of the product candidate being tested or for other unforeseen reasons.

In addition, our potential milestone and royalty providers may conduct clinical trials in foreign countries, which may subject them to further delays and expenses as a result of increased drug shipment costs, additional regulatory requirements and the engagement of foreign clinical research organizations, and may expose our potential milestone and royalty providers to risks associated with foreign currency transactions to make contract payments denominated in the foreign currency where the trial is being conducted.

New products and technologies of other companies may render some or all of our potential milestone and royalty providers’ product candidates noncompetitive or obsolete.

New developments by others may render our potential milestone and royalty providers’ product candidates or technologies obsolete or uncompetitive. Technologies developed and utilized by the biotechnology and pharmaceutical industries are changing continuously and substantially. Competition in antibody-based technologies is intense and is expected to increase in the future as a number of established biotechnology firms and large chemical and pharmaceutical companies advance in these fields. Many of these competitors may be able to develop products and processes competitive with or superior to our potential milestone and royalty providers for many reasons, including that they may have:

significantly greater financial resources;
larger research and development staffs;
entered into arrangements with, or acquired, biotechnology companies to enhance their capabilities; or
extensive experience in preclinical testing and human clinical trials.

These factors may enable others to develop products and processes competitive with or superior to our own or those of our potential milestone and royalty providers. In addition, a significant amount of research in biotechnology is being carried out in universities and other non-profit research organizations. These entities are becoming increasingly interested in the commercial value of their work and may become more aggressive in seeking patent protection and licensing arrangements. Furthermore, many companies and universities tend not to announce or disclose important discoveries or development programs until their patent position is secure or, for other reasons, later. As a result, we and our potential milestone and royalty providers may not be able to track development of competitive products, particularly at the early stages.

Positive developments in connection with a potentially competing product may have an adverse impact on our future potential for receiving revenue derived from development milestones and royalties. For example, if another product is perceived to have a competitive advantage, or another product’s failure is perceived to increase the likelihood that our licensed product will fail, our potential milestone and royalty providers may halt development of product candidates in which we have an interest.

Our potential royalty providers may be unable to price our products effectively or obtain coverage and adequate reimbursement for sales of our products, which would prevent our potential royalty providers’ products from becoming profitable and negatively affect the royalties we may receive.

If our potential royalty providers succeed in bringing our product candidates to the market, they may not be considered cost effective, and reimbursement to the patient may not be available or may not be sufficient to allow our

31

Table of Contents

potential royalty providers to sell the products on a competitive basis. In both the United States and elsewhere, sales of medical products and treatments are dependent, in part, on the availability of coverage and adequate reimbursement from third-party payors, such as government and private insurance plans. Significant uncertainty exists as to the coverage and reimbursement status of any products for which our potential royalty providers may obtain regulatory approval. Even if coverage is available, the associated reimbursement rate may not be adequate for our potential royalty providers to cover related costs. Additionally, coverage and reimbursement policies for drug products can differ significantly from payor to payor as there is no uniform policy of coverage and reimbursement for drug products among third-party payors in the United States. Therefore, the process of obtaining coverage and reimbursement is often time-consuming and costly.

Third-party payors are increasingly challenging the prices charged for pharmaceutical products and services. Our business is affected by the efforts of government and third-party payors to contain or reduce the cost of healthcare through various means. In the United States, there have been and will continue to be a number of federal and state proposals to implement government controls on pricing.

In addition, the emphasis on managed care in the United States has increased and will continue to increase the pressure on the pricing of pharmaceutical products. We cannot predict whether any legislative or regulatory proposals will be adopted or the effect these proposals or managed care efforts may have on our or our potential milestone and royalty providers’ businesses.

We do not know whether there will be, or will continue to be, a viable market for the product candidates in which we have an ownership or royalty interest.

Even if product candidates in which we have an interest receive approval in the future, they may not be accepted in the marketplace. In addition, our potential royalty providers may experience difficulties in launching new products, many of which are novel and based on technologies that are unfamiliar to the healthcare community. We have no assurance healthcare providers and patients will accept such products, if developed. Similarly, physicians may not accept a product if they believe other products to be more effective or more cost effective or are more comfortable prescribing other products.

Furthermore, government agencies, as well as private organizations involved in healthcare, from time to time publish guidelines or recommendations to healthcare providers and patients. Such guidelines or recommendations can be very influential and may adversely affect product usage directly (for example, by recommending a decreased dosage of a product in conjunction with a concomitant therapy) or indirectly (for example, by recommending a competitive product over a product in which we have an ownership or royalty interest). Consequently, we do not know if physicians or patients will adopt or use products in which we have an ownership or royalty interest for their approved indications.

Even approved and marketed products are subject to risks relating to changes in the market for such products. Introduction or increased availability of generic or biosimilar versions of products can alter the market acceptance of branded products. In addition, unforeseen safety issues may arise at any time, regardless of the length of time a product has been on the market.

We are exposed to an increased risk of product liability claims.

The testing, marketing and sales of medical products entails an inherent risk of allegations of product liability. In the past, we were party to product liability claims filed against Genentech Inc. and, even though Genentech agreed to indemnify us in connection with these matters and these matters have been settled, there can be no assurance other product liability lawsuits will not result in liability to us or that our insurance or contractual arrangements will provide us with adequate protection against such liabilities. In the event of one or more large, unforeseen awards of damages against us, our product liability insurance may not provide adequate coverage. A significant product liability claim for which we were not covered by insurance or indemnified by a third party would have to be paid from cash or other assets, which could have an adverse effect on our business and the value of our common stock. To the extent we have sufficient insurance coverage, such a claim would presumably result in higher subsequent insurance rates. In addition, product liability claims can have various other ramifications, including loss of future sales opportunities, increased costs associated with replacing

32

Table of Contents

products, a negative impact on our goodwill and reputation, and divert our management’s attention from our business, each of which could also adversely affect our business and operating results.

If we and our potential royalty providers are unable to protect our intellectual property, in particular patent protection for principal products, product candidates and processes in which we have an ownership or royalty interest, and prevent the use of the covered subject matter by third parties, our potential royalty providers’ ability to compete in the market will be harmed, and we may not realize our profit potential.

We and our potential royalty providers rely on patent protection, as well as a combination of copyright, trade secret, and trademark laws to protect our proprietary technology and prevent others from duplicating our products or product candidates. However, these means may afford only limited protection and may not:

prevent our competitors from duplicating our products and those of our potential royalty providers;
prevent our competitors from gaining access to our proprietary information and technology and that of our potential royalty providers; or
permit us or our potential royalty providers to gain or maintain a competitive advantage.

Because of the length of time and the expense associated with bringing new products to the marketplace, we and our potential royalty providers hold and are in the process of applying for a number of patents in the United States and abroad to protect product candidates and important processes and also have obtained or have the right to obtain exclusive licenses to certain patents and applications filed by others. However, the mere issuance of a patent is not conclusive as to its validity or its enforceability.

The U.S. Federal Courts, the U.S. Patent & Trademark Office or equivalent national courts or patent offices elsewhere may invalidate our patents or find them unenforceable. The America Invents Act introduced post-grant review procedures subjecting U.S. patents to post-grant review procedures similar to European oppositions. U.S. patents owned or licensed by us or our licensees may therefore be subject to post-grant review procedures, as well as other forms of review and re-examination. A decision in such proceedings adverse to our interests could result in the loss of valuable patent rights, which would have a material adverse effect on our business. In addition, the laws of foreign countries may not protect our intellectual property rights effectively or to the same extent as the laws of the United States.

If our, and our potential royalty providers intellectual property rights are not protected adequately, our potential royalty providers may not be able to commercialize technologies or products in which we have an ownership or royalty interest, and our competitors could commercialize such technologies or products, which could result in a decrease in our potential royalty providers’ sales and market share that would harm our business and operating results. Specifically, the patent position of biotechnology companies generally is highly uncertain and involves complex legal and factual questions. The legal standards governing the validity of biotechnology patents are in transition, and current defenses as to issued biotechnology patents may not be adequate or available in the future. Accordingly, there is uncertainty as to:

whether any pending or future patent applications held by us or our potential royalty providers will result in an issued patent, or whether issued patents will provide meaningful protection against competitors or competitive technologies;
whether competitors will be able to design around our or our potential royalty providers’ patents or develop and obtain patent protection for technologies, designs or methods that are more effective than those covered by our or our potential royalty providers’ patents and patent applications; or
the extent to which our or our potential royalty providers’ product candidates could infringe on the intellectual property rights of others, which may lead to costly litigation, result in the payment of substantial damages or royalties, reduce the royalty rate due to us, and prevent our potential royalty providers from using our technology or product candidates.

33

Table of Contents

If certain patents issued to others are upheld or if certain patent applications filed by others are issued and upheld, our potential royalty providers may require licenses from others to develop and commercialize certain potential products in which we have an ownership or royalty interest. These licenses, if required, may not be available on acceptable terms, or may trigger contractual royalty offset clauses in our license agreements, or those of our royalty-agreement counterparties. We may become involved in litigation to determine the proprietary rights of others, and any such litigation will presumably be costly and may have other adverse effects on our business, such as inhibiting our potential royalty providers’ ability to compete in the marketplace and absorbing significant management time.

Due to the uncertainties regarding biotechnology patents, we also have relied and will continue to rely upon trade secrets, know-how and continuing technological advancement to develop and maintain our competitive position. Our employees and contractors are typically required to sign confidentiality agreements under which they agree not to use or disclose any of our proprietary information. Research and development contracts and relationships between us and our scientific consultants and potential licensees provide access to aspects of our know-how that are protected generally under confidentiality agreements. These confidentiality agreements may be breached or may not be enforced by a court. To the extent proprietary information is divulged to competitors or to the public generally, such disclosure may adversely affect our licensees’ ability to develop or commercialize our products by giving others a competitive advantage or by undermining our patent position.

Litigation regarding intellectual property and/or the enforcement of our contractual rights against licensees and third parties can be costly and expose us to risks of counterclaims against us.

We may be required to engage in litigation or other proceedings to protect our intellectual property and/or enforce our contractual rights against former or current licensees or third parties, including third-party collaborators of such licensees. The cost to us of this litigation, even if resolved in our favor, could be substantial and parties to such litigation may be able to sustain the cost of such litigation and proceedings more effectively than we can if they have substantially greater resources than us. Such litigation and any negotiations leading up to it also could divert management’s attention and resources. If this litigation is resolved against us, we may lose the value associated with contract rights contained in our arrangements with licensees and third parties, our patents may be declared invalid, and we could be held liable for significant damages. While it is our current plan to pursue, on a selective basis, potential material contractual breaches against licensees and third parties (including third-party collaborators of licensees) and/or infringement of our intellectual property rights or technology, there can be no assurance that any such enforcement actions will be successful, or if successful, the timing of such success or that we will have sufficient capital to prosecute any such actions to a successful conclusion.

In addition, we may be subject to claims that we, or our licensees, are infringing other parties’ patents. If such claims are resolved against us, we or our licensees may be enjoined from developing, manufacturing, selling or importing products, processes or services unless we obtain a license from the other party. Such license may not be available on reasonable terms or at all, thus preventing us, or our licensees, from using these products, processes or services and adversely affecting our potential future revenue.

Uncertainties resulting from our participation in intellectual property litigation or other proceedings could have a material adverse effect on our ability to compete in the marketplace. There could also be public announcements of the results of hearings, motions or interim proceedings or developments. If securities analysts or investors perceive these results to be negative, the perceived value of the drug product candidates as to which we hold future potential milestone or royalty interests, or intellectual property could be diminished. Accordingly, the market price of our common stock may decline. Uncertainties resulting from the initiation and continuation of intellectual property litigation or other proceedings could have a material adverse effect of our business, financial condition and results of operation.

Risks Related to Employees, Location, Data Integrity, and Litigation

The loss or COVID-19 related absence of any of our personnel, including our Chief Executive Officer or Chief Financial Officer, could delay or prevent achieving our objectives.

Our business efforts could be adversely affected by the loss or COVID-19 related absence of one or more key members of our staff, including our executive officers: James R. Neal, our Chief Executive Officer and Thomas Burns, our Senior Vice President, Finance and Chief Financial Officer. We currently do not have key person insurance on any of our employees. In addition, given our minimal employee base, a COVID-19 outbreak in our employee population could significantly hinder our ability to meet our operating objectives.

Because we are a small biopharmaceutical focused company with limited resources, we may not be able to attract and retain qualified personnel.

We had 10 employees as of March 5, 2021. We may require additional experienced executive, accounting, legal, administrative and other personnel from time to time in the future. There is intense competition for the services of these personnel, especially in California. Moreover, we expect that the high cost of living in the San Francisco Bay Area, where our headquarters is located, may impair our ability to attract and retain employees in the future. If we do not succeed in attracting new personnel and retaining and motivating existing personnel, our business may suffer and we may be unable to implement our current initiatives or grow effectively.

We rely and will continue to rely on outsourcing arrangements for many of our activities, including financial reporting and accounting and human resources.

Due to our small number of employees, we rely, and expect to continue to rely, on outsourcing arrangements for a significant portion of our activities, including financial reporting and accounting and human resources, as well as for certain of our functions as a public company. We may have limited control over these third parties and we cannot guarantee that they will perform their obligations in an effective and timely manner.

Our employees may engage in misconduct or other improper activities, including noncompliance with regulatory standards and requirements and insider trading.

We are exposed to the risk of employee fraud or other misconduct. Misconduct by employees could include intentional failures to comply with applicable regulations, provide accurate information to regulatory authorities, comply with federal and state fraud and abuse laws and regulations, report financial information or data accurately or disclose unauthorized activities to us. In particular, the health care industry is subject to extensive laws and regulations intended to prevent fraud, misconduct, kickbacks, self-dealing and other abusive practices. It is not always possible to identify and deter employee misconduct, and the precautions we take to detect and prevent this activity may not be effective in controlling unknown or unmanaged risks or losses or in protecting us from governmental investigations or other actions or lawsuits stemming from a failure to be in compliance with these laws or regulations. If any such actions are instituted against us, and we are not successful in defending ourselves or asserting our rights, those actions could have a significant impact on our business, including the imposition of significant fines or other sanctions.

Natural disasters, power shortages, power interruptions or other calamities at our Emeryville headquarters could disrupt our business and adversely affect our operations.

Our corporate headquarters is located in Emeryville, California. This location is in an area of seismic activity near active earthquake faults. Any earthquake, tsunami, terrorist attack, riot, fire, power shortage or other calamity affecting our facilities may disrupt our business and could have material adverse effect on our results of operations.

If a natural disaster, power outage or other event occurred that prevented us from using all or a significant portion of our headquarters, that damaged critical infrastructure or that otherwise disrupted operations, it may be difficult or, in certain cases, impossible for us to continue our business for a substantial period of time. We may incur substantial expenses

35

as a result of the limited nature of our disaster recovery and business continuity plans, which, particularly when taken together with our lack of earthquake insurance, could have a material adverse effect on our business.

Our business and operations would suffer in the event of system failures.

Despite the implementation of security measures, our internal computer systems and those of our current and any future licensees, suppliers, contractors and consultants are vulnerable to damage from cyberattacks, computer viruses, unauthorized access, natural disasters, terrorism, war and telecommunication and electrical failures. We could experience failures in our information systems and computer servers, which could be the result of a cyberattacks and could result in an interruption of our normal business operations and require substantial expenditure of financial and administrative resources to remedy. System failures, accidents or security breaches can cause interruptions in our operations and can result in a material disruption of our development programs and other business operations. The loss of clinical trial data from completed or future clinical trials could result in delays in our regulatory approval efforts and significantly increase our costs to recover or reproduce the data. Similarly, we rely on third parties to manufacture our product candidates, and conduct clinical trials of our product candidates, and similar events relating to their computer systems could also have a material adverse effect on our business. To the extent that any disruption or security breach were to result in a loss of, or damage to, our data or applications, or inappropriate disclosure of confidential or proprietary information, we could incur liability and the development of any of our product candidates could be delayed or otherwise adversely affected.

Data breaches and cyberattacks could compromise our intellectual property or other sensitive information and cause significant damage to our business and reputation.

In the ordinary course of our business, we maintain sensitive data on our networks, including our intellectual property and proprietary or confidential business information relating to our business and that of our customers and business partners. The secure maintenance of this information is critical to our business and reputation. We believe companies have been increasingly subject to a wide variety of security incidents, cyberattacks and other attempts to gain unauthorized access. These threats can come from a variety of sources, all ranging in sophistication from an individual hacker to a state-sponsored attack. Cyber threats may be generic, or they may be custom-crafted against our information systems. Cyberattacks have become more prevalent and much harder to detect and defend against. Our network and storage applications may be subject to unauthorized access by hackers or breached due to operator error, malfeasance or other system disruptions. It is often difficult to anticipate or immediately detect such incidents and the damage caused by such incidents. These data breaches and any unauthorized access or disclosure of our information or intellectual property could compromise our intellectual property and expose sensitive business information. A data security breach could also lead to public exposure of personal information of our clinical trial patients, customers and others which could expose us to liability under federal or state privacy laws. Cyberattacks can result in the theft of proprietary information which could be used to compete against us and could cause us to incur significant remediation costs, result in product development delays, disrupt key business operations and divert attention of management and key information technology resources. These incidents could also subject us to liability, expose us to significant expense and cause significant harm to our reputation and business.

U.S. and international authorities have been warning businesses of increased cybersecurity threats from actors seeking to exploit the COVID-19 pandemic. Moreover, failure to maintain effective internal accounting controls related to data security breaches and cybersecurity in general could impact our ability to produce timely and accurate financial statements and could subject us to regulatory scrutiny. In addition, these breaches and other inappropriate access can be difficult to detect, and any delay in identifying them may lead to increased harm of the type described above. Moreover, the prevalent use of mobile devices that access confidential information increases the risk of data security breaches, which could lead to the loss of confidential information, trade secrets or other intellectual property. While we have implemented security measures that are intended to protect our data security and information technology systems, such measures may not prevent such events.

Significant disruptions of information technology systems, including cloud-based systems, or breaches of data security could adversely affect our business.

Our business is increasingly dependent on critical, complex and interdependent information technology systems, including cloud-based systems, to support business processes as well as internal and external communications. Our computer systems, and those of our partners and contractors, are potentially vulnerable to breakdown, malicious intrusion and computer viruses that may result in the impairment of key business processes. Such disruptions and breaches of security could have a material adverse effect on our business, financial condition and results of operations.

In addition, our data security and information technology systems, as well as those of our partners and contractors, are potentially vulnerable to data security breaches, whether by employees or others, that may expose sensitive data or personal information to unauthorized persons. Effective May 25, 2018, the European Union (“EU”) implemented the General Data Protection Regulation (“GDPR”) a broad data protection framework that expands the scope of current EU data protection law to non-European Union entities that process, or control the processing of, the personal information of EU subjects, including clinical trial data. The GDPR allows for the imposition of fines and/or corrective action on entities that improperly use or disclose the personal information of EU subjects, including through a data security breach.

The California Consumer Privacy Act became effective on January 1, 2020 and its applicable regulations are being implemented in waves by the California Attorney General, including additional regulations that were still in the comment phase at the end of 2020 (collectively the Act and its regulations, “CCPA”). The CCPA establishes a privacy framework for covered businesses, including an expansive definition of personal information and data privacy rights for California residents. The CCPA includes a framework with potentially severe statutory damages and private rights of action. The CCPA requires covered companies to provide new disclosures to California consumers (as that word is broadly defined in the CCPA), provide such consumers new ways to opt-out of certain sales of personal information, and allow for a new cause of action for data breaches. As we expand our operations, the CCPA will likely impact our business activities and may increase our compliance costs and potential liability. If we fail to comply with the CCPA, including all of the various and recent waves of its implementing regulations, we may face significant fines and penalties that could adversely affect our business, financial condition and results of operations. Other states are beginning to pass similar laws, and some observers have noted that the CCPA could mark the beginning of a trend toward more stringent privacy legislation in the United States, which could increase our potential liability and adversely affect our business. Accordingly, data security breaches experienced by us, our partners or contractors could lead to significant fines, required corrective action, the loss of trade secrets or other intellectual property, public disclosure of sensitive clinical or commercial data, and the exposure of personally identifiable information (including sensitive personal information) of our employees, partners, and others. A data security breach or privacy violation that leads to disclosure or modification of, or prevents access to, patient information, including personally identifiable information or protected health information, could result in fines, increased costs or loss of revenue as a result of:

harm to our reputation;
fines imposed on us by regulatory authorities;
additional compliance obligations under federal, state or foreign laws;
requirements for mandatory corrective action to be taken by us; and
requirements to verify the correctness of database contents and otherwise subject us to liability under laws and regulations that protect personal data.

If we are unable to prevent such data security breaches or privacy violations or implement satisfactory remedial measures, our operations could be disrupted, and we may suffer loss of reputation, financial loss and other regulatory penalties because of lost or misappropriated information, including sensitive patient data. In addition, these breaches and other inappropriate access can be difficult to detect, and any delay in identifying them may lead to increased harm of the type described above. Moreover, the prevalent use of mobile devices that access confidential information increases the risk of data security breaches, which could lead to the loss of confidential information, trade secrets or other intellectual

property. While we have implemented security measures to protect our data security and information technology systems, such measures may not prevent such events. We expect that there will continue to be new proposed laws, regulations and industry standards relating to privacy and data protection in the United States, the EU and other jurisdictions, such as the CCPA. We cannot presently determine the impact such laws, regulations and standards will have on our business. It is possible that the GDPR, CCPA or other laws and regulations relating to privacy and data protection may be interpreted and applied in a manner that is inconsistent from jurisdiction to jurisdiction or inconsistent with our current policies and practices and compliance with such laws and regulations could require us to change our business practices and compliance procedures in a manner adverse to our business. We cannot guarantee that we are in compliance with all such applicable data protection laws and regulations as they are enforced now or as they evolve.

Risks Related to Government Regulation

Even after FDA approval, a product may be subject to additional testing or significant marketing restrictions, its approval may be withdrawn or it may be removed voluntarily from the market.

Even if our potential royalty providers receive regulatory approval for our product candidates, our licensees will be subject to ongoing regulatory oversight and review by the FDA and other regulatory entities. The FDA, the EMA, or another regulatory agency may impose, as a condition of the approval, ongoing requirements for post-approval studies or post-approval obligations, including additional research and development and clinical trials, and the FDA, EMA or other regulatory agency subsequently may withdraw approval based on these additional trials or obligations.

Even for approved products, the FDA, EMA or other regulatory agency may impose significant restrictions on the indicated uses, conditions for use, labeling, advertising, promotion, marketing and production of such product. In addition, the labeling, packaging, adverse event reporting, storage, advertising, promotion and record-keeping for our products are subject to extensive regulatory requirements.

Furthermore, marketing approval of a product may be withdrawn by the FDA, the EMA or another regulatory agency or such product may be withdrawn voluntarily by our potential royalty providers based, for example, on subsequently arising safety concerns. The FDA, EMA and other agencies also may impose various civil or criminal sanctions for failure to comply with regulatory requirements, including withdrawal of product approval.

Healthcare reform measures and other statutory or regulatory changes could adversely affect our business.

The United States and some foreign jurisdictions have enacted or are considering a number of legislative and regulatory proposals to change the healthcare system in ways that could affect our potential royalty providers’ ability to sell products in which we have ownership or and royalty interests, if approved, profitably. Among policy makers and payors in the United States and elsewhere, there is significant interest in promoting changes in healthcare systems with the stated goals of containing healthcare costs, improving quality and expanding access. In the United States, the pharmaceutical industry has been a particular focus of these efforts and has been significantly affected by major legislative initiatives. Since January 2017, President Trump signed several executive orders and other directives designed to delay, circumvent, or loosen certain requirements mandated by ACA. Concurrently, Congress considered legislation that would repeal or repeal and replace all or part of ACA. While Congress has not passed comprehensive repeal legislation, several bills affecting the implementation of certain taxes under the ACA have been signed into law. The Tax Cuts and Jobs Act of 2017, or Tax Act, includes a provision repealing, effective January 1, 2019, the tax-based shared responsibility payment imposed by ACA on certain individuals who fail to maintain qualifying health coverage for all or part of a year that is commonly referred to as the “individual mandate”. In addition, the 2020 federal spending package permanently eliminated, effective January 1, 2020, the ACA-mandated “Cadillac” tax on high-cost employer-sponsored health coverage and medical device tax and, effective January l, 2021, also eliminated the health insurer tax. The Bipartisan Budget Act of 2018, or the BBA, among other things, amends the ACA, effective January 1, 2019, to increase from 50 percent to 70 percent the point-of-sale discount that is owed by pharmaceutical manufacturers who participate in Medicare Part D and close the coverage gap in most Medicare drug plans, commonly referred to as the “donut hole”. On December 14, 2018, a Texas U.S. District Court Judge ruled that the ACA is unconstitutional in its entirety because the “individual mandate” was repealed by Congress as part of the Tax Act. Additionally, on December 18, 2019, the U.S. Court of Appeals for the 5th Circuit upheld the District Court ruling that the individual mandate was unconstitutional and remanded the case back

to the District Court to determine whether the remaining provisions of the ACA are invalid as well. The U.S. Supreme Court is currently reviewing this case, but it is unknown when a decision will be reached. Although the U.S. Supreme Court has yet ruled on the constitutionality of the ACA, on January 28, 2021, President Biden issued an executive order to initiate a special enrollment period from February 15, 2021 through May 15, 2021 for purposes of obtaining health insurance coverage through the ACA marketplace. The executive order also instructs certain governmental agencies to review and reconsider their existing policies and rules that limit access to healthcare, including among others, reexamining Medicaid demonstration projects and waiver programs that include work requirements, and policies that create unnecessary barriers to obtaining access to health insurance coverage through Medicaid or the ACA. It is unclear how the Supreme Court ruling, other such litigation, and the healthcare reform measures will impact the ACA and our business.

Other legislative changes have also been proposed and adopted since the ACA was enacted. For example, the Budget Control Act of 2011 resulted in aggregate reductions in Medicare payments to providers of up to two percent per fiscal year, starting in 2013 and, due to subsequent legislative amendments to the statute, including the BBA, will remain in effect through 2030 unless additional Congressional action is taken. However, COVID-19 relief support legislation suspended the 2% Medicare sequester from May 1, 2020 through March 31, 2021. In addition, the American Taxpayer Relief Act of 2012, among other things, reduced Medicare payments to several types of providers and increased the statute of limitations period for the government to recover overpayments to providers from three to five years. Such laws, and others that may affect our business that have been recently enacted or may in the future be enacted, may result in additional reductions in Medicare and other healthcare funding.

Also, there has been heightened governmental scrutiny recently in the U.S. over pharmaceutical pricing practices in light of the rising cost of prescription drugs and biologics. Such scrutiny has resulted in several recent Congressional inquiries and proposed and enacted federal and state legislation designed to, among other things, bring more transparency to product pricing, review the relationship between pricing and manufacturer patient programs, and reform government program reimbursement methodologies for products. At the federal level, the Trump administration used several means to propose or implement drug pricing reform, including through federal budget proposals, executive orders and policy initiatives. For example, on July 24, 2020 and September 13, 2020, the Trump administration announced several executive orders related to prescription drug pricing that attempt to implement several of the administration’s proposals. The FDA also released a final rule, effective November 30, 2020, implementing a portion of the importation executive order providing guidance for states to build and submit importation plans for drugs from Canada. Further, on November 20, 2020, HHS finalized a regulation removing safe harbor protection for price reductions from pharmaceutical manufacturers to plan sponsors under Part D, either directly or through pharmacy benefit managers, unless the price reduction is required by law. The implementation of the rule has been delayed by the Biden administration from January 1, 2022 to January 1, 2023 in response to ongoing litigation. The rule also creates a new safe harbor for price reductions reflected at the point-of-sale, as well as a new safe harbor for certain fixed fee arrangements between pharmacy benefit managers and manufacturers, the implementation of which have also been delayed pending review by the Biden administration until March 22, 2021. On November 20, 2020, CMS issued an interim final rule implementing President Trump’s Most Favored Nation executive order, which would tie Medicare Part B payments for certain physician-administered drugs to the lowest price paid in other economically advanced countries, effective January 1, 2021. On December 28, 2020, the United States District Court in Northern California issued a nationwide preliminary injunction against implementation of the interim final rule. However, it is unclear whether the Biden administration will work to reverse these measures or pursue similar policy initiatives. At the state level, legislatures have increasingly passed legislation and implemented regulations designed to control pharmaceutical and biological product pricing, including price or patient reimbursement constraints, discounts, and restrictions on certain product access. In some cases, such legislation and regulations have been designed to encourage importation from other countries and bulk purchasing.

An expansion in the government’s role in the U.S. healthcare industry may cause general downward pressure on the prices of prescription drug products, lower reimbursements for providers, and reduced product utilization, any of which could adversely affect our business and results of operations. Moreover, there has been heightened governmental scrutiny in the United States of pharmaceutical pricing practices in light of the rising cost of prescription drugs and biologics. Such scrutiny has resulted in several recent congressional inquiries and proposed and enacted federal and state legislation designed to, among other things, bring more transparency to product pricing, review the relationship between pricing and manufacturer patient programs, and reform government program reimbursement methodologies for products. We cannot know what form any such new legislation may take or the market’s perception of how such legislation would affect us.

Any reduction in reimbursement from government programs may result in a similar reduction in payments from private payors. The implementation of cost containment measures or other healthcare reforms may prevent our potential royalty providers from being able to generate revenue, attain profitability, develop, or commercialize our current product candidates in which we have an ownership or royalty interest.

We and our potential milestone and royalty providers are subject to various state and federal healthcare-related laws and regulations that may impact the commercialization of product candidates for which we possess milestone or royalty rights or could subject us to significant fines and penalties.

Our operations may be directly or indirectly subject to various state and federal healthcare laws, including the federal Anti-Kickback Statute, the federal False Claims Act and state and federal data privacy and security laws. These laws may impact, among other things, the commercial operations for any of our product candidates that may be approved for commercial sale.

The federal Anti-Kickback Statute prohibits, among other things, persons and entities from knowingly and willfully soliciting, offering, receiving or providing any remuneration, directly or indirectly, in cash or in kind, in exchange for or to induce either the referral of an individual for, or the furnishing or arranging for the purchase, lease, or order of a good or service for which payment may be made under a federal healthcare program, such as the Medicare and Medicaid programs. The ACA modified the federal Anti-Kickback Statute’s intent requirement so that a person or entity no longer needs to have actual knowledge of the statute or the specific intent to violate it to have committed a violation. In addition, several courts have interpreted the statute’s intent requirement to mean that if any one purpose of an arrangement involving remuneration is to induce referrals of federal healthcare covered business, the statute has been violated. The Anti-Kickback Statute is broad and prohibits many arrangements and practices that are lawful in businesses outside of the healthcare industry.

The federal false claims laws, including the False Claims Act, and civil monetary penalties laws prohibit, among other things, persons and entities from knowingly filing, or causing to be filed, a false claim to, or the knowing use of false statements to obtain payment from the federal government. Certain suits filed under the False Claims Act, known as “qui tam” actions, can be brought by any individual on behalf of the government and such individual, commonly known as a “whistleblower,” may share in any amounts paid by the entity to the government in fines or settlement. The filing of qui tam actions has caused a number of pharmaceutical, medical device and other healthcare companies to have to defend and/or settle a False Claims Act action.

The Federal Health Insurance Portability and Accountability Act of 1996 (“HIPAA”) created new federal criminal statutes that prohibit, among other things, executing a scheme to defraud any healthcare benefit program, including a private payor, or falsifying, concealing or covering up a material fact or making any materially false, fictitious or fraudulent statement in connection with the delivery of, or payment for, health care benefits, items or services.

HIPAA, as amended by the Health Information Technology and Clinical Health Act, and its implementing regulations, also imposes certain requirements relating to the privacy, security and transmission of individually identifiable health information by entities subject to the law, such as certain healthcare providers, health plans, and healthcare clearinghouses as well as their respective business associates that perform certain functions or activities that involve the use or disclosure of protected health information on their behalf.

Many states also have adopted laws similar to each of the federal laws described above, some of which apply to healthcare items or services reimbursed by any source, not only federal healthcare programs, such as the Medicare and Medicaid programs. In addition, some states have laws that require pharmaceutical companies to comply with the pharmaceutical industry’s voluntary compliance guidelines and the applicable compliance guidance promulgated by the federal government. Additionally, certain state and local laws require the registration of pharmaceutical sales representatives, restrict payments that may be made to healthcare providers and other potential referral sources, and require manufacturers to report information related to payments and other transfers of value to physicians and other healthcare providers. Further, some states have laws governing the privacy and security of health information in certain circumstances, many of which are not preempted by HIPAA and differ from each other in significant ways and may not have the same effect, thus complicating compliance efforts.

Because of the breadth of these laws, and the narrowness of the statutory exceptions and regulatory safe harbors available, it is possible that some of our or our potential milestone and royalty providers’ business activities could be subject to challenge under one or more of such laws.

If we or our potential milestone and royalty providers are found to be in violation of any of the laws and regulations described above or other applicable state and federal healthcare laws, we or our potential milestone and royalty providers may be subject to penalties, including significant civil, criminal, and administrative penalties, damages, fines, disgorgement, imprisonment, integrity oversight and reporting obligations, reputational harm, exclusion from government healthcare reimbursement programs and the curtailment or restructuring of our or our potential milestone and royalty providers’ operations, any of which could have a material adverse effect on our business and results of operations. In addition, we and our licensees may be subject to certain analogous foreign laws and violations of such laws could result in significant penalties.

As we or our potential milestone and royalty providers do more business internationally, we will be subject to additional political, economic and regulatory uncertainties.

We or our potential milestone and royalty providers may not be able to operate successfully in any foreign market. We believe that because the pharmaceutical industry is global in nature, international activities will be a significant part of future business activities and when and if we or our potential milestone and royalty providers are able to generate income, a substantial portion of that income will be derived from product sales and other activities outside the United States. Foreign regulatory agencies often establish standards different from those in the United States, and an inability to obtain foreign regulatory approvals on a timely basis could put us at a competitive disadvantage or make it uneconomical to proceed with a product or product candidate’s development. International sales may be limited or disrupted by many factors, including without limitation:

imposition of government controls;
export license requirements;
political or economic instability;
trade restrictions;
changes in tariffs;
restrictions on repatriating profits;
exchange rate fluctuations; and
withholding and other taxation.

General Risk Factors

Our share price may be volatile, and there may not be an active trading market for our common stock or Series A preferred stock.

There can be no assurance that the market price of our common stock will not decline below its present market price. Additionally, there may not be an active trading market for our common stock or Series A preferred stock. The market prices of biotechnology companies have been and are likely to continue to be highly volatile. Fluctuations in our operating results and general market conditions for biotechnology stocks could have a significant impact on the volatility of our stock price or the existence of an active trading market for our common stock or Series A preferred stock. We have experienced significant volatility in the price of our common stock. From January 1, 2020, through March 5, 2021, the

41

Table of Contents

share price of our common stock has ranged from a high of $46.32 to a low of $14.14. Additionally, we have one significant holder of our stock that could affect the liquidity of our stock and have a significant negative impact on our stock price if the holder was to quickly sell their ownership position.

Our results of operations and liquidity needs could be materially negatively affected by market fluctuations or an economic downturn.

Our results of operations could be materially negatively affected by economic conditions generally, both in the United States and elsewhere around the world. Concerns over inflation, energy costs, geopolitical issues, the availability and cost of credit, and the U.S. financial markets have in the past contributed to, and may continue in the future contribute to, increased volatility and diminished expectations for the economy and the markets. Domestic and international equity markets periodically experience heightened volatility and turmoil. These events may have an adverse effect on us. In the event of a market downturn, our results of operations could be adversely affected by those factors in many ways, including making it more difficult for us to raise funds if necessary, and our stock price may decline.

We have issued equity securities, and may issue additional equity securities from time to time, that materially and adversely affect the price of our common stock, including our Series X preferred stock and our Series A preferred stock.

We expect that significant additional capital will be needed in the future to continue our planned operations. To the extent we raise additional capital by issuing equity securities, our stockholders may experience substantial dilution. We may sell common stock, convertible securities or other equity securities in one or more transactions at prices and in such a manner as we determine from time to time, including pursuant to our 2018 ATM Agreement, as amended. If we sell common stock, convertible securities or other equity securities in more than one transaction, investors may be materially diluted by subsequent sales. These sales may also result in material dilution to our existing stockholders, and new investors could gain rights superior to our existing stockholders. If we issue additional equity securities, the price of our common stock may be materially and adversely affected.

As of December 31, 2020, there were 984,000 shares of Series A preferred stock and 5,003 shares of Series X preferred stock issued and outstanding. Each share of Series X preferred stock is convertible into 1,000 shares of registered common stock. The total number of shares of common stock issuable upon conversion of all issued Series X preferred stock would be 5,003,000 shares. Each share is convertible at the option of the holder at any time, provided that the holder will be prohibited from converting into common stock if, as a result of such conversion, the holder, together with its affiliates, would beneficially own a number of shares above a conversion blocker, which was initially set at 19.99% of our total common stock then issued and outstanding immediately following the conversion of such shares. A holder of Series X preferred shares may elect to increase or decrease the conversion blocker above or below 19.99% on 61 days’ notice, provided the conversion blocker does not exceed the limits under Nasdaq Marketplace Rule 5635(b), to the extent then applicable. If holders of our Series X convertible preferred stock elect to convert their preferred shares into common stock such conversion would dilute our currently outstanding common stock both in number and in earnings per share. BVF (and its affiliates), as current holders of all shares of our Series X preferred stock, would, if they converted all such shares to common stock, obtain majority voting control of the Company. In February 2020, Biotechnology Value Fund, L.P. (“BVF”), the holders of Series Y convertible preferred shares, elected to increase the beneficial ownership limitation to 50% and on April 15, 2020, BVF converted all of their shares of Series Y preferred stock into 1,252,772 shares of common stock. As of December 31, 2020, BVF owned approximately 37.2% of our total outstanding shares of common stock, and if all the Series X convertible preferred shares were converted, BVF would own 56.6% of our total outstanding shares of common stock.

We may sell additional equity or debt securities to fund our operations, which may result in dilution to our stockholders and impose payment obligations or restrictions on our business.

In order to raise additional funds to support our operations, we may sell additional equity or convertible debt securities, which would result in dilution to our stockholders and/or debt securities which may impose restrictive covenants that would adversely impact our business. The sale of additional equity or convertible debt securities could result in additional dilution or result in other rights or obligations that adversely affect our stockholders. For example, holders of shares of our Series A preferred stock are entitled to receive, when and as declared by our Board of Directors, out of funds

42

Table of Contents

legally available for the payment of dividends, cumulative cash dividends at the rate of 8.625% of the $25.00 liquidation preference per year (equivalent to $2.15625 per year). The incurrence of indebtedness would result in increased fixed payment obligations and could also result in certain restrictive covenants, such as limitations on our ability to incur additional debt, limitations on our ability to acquire, sell or license intellectual property rights and other operating restrictions that could adversely impact our ability to conduct our business. If we are unable to expand our operations or otherwise capitalize on our business opportunities, our business, financial condition and results of operations could be materially adversely affected and we may not be able to meet our debt service obligations.

Our organizational documents contain provisions that may prevent transactions that could be beneficial to our stockholders and may insulate our management from removal.

Our charter and by-laws:

require certain procedures to be followed and time periods to be met for any stockholder to propose matters to be considered at annual meetings of stockholders, including nominating directors for election at those meetings; and
authorize our Board of Directors to issue up to 1,000,000 shares of preferred stock without stockholder approval and to set the rights, preferences and other designations, including voting rights, of those shares as the Board of Directors may determine.

In addition, we are subject to the provisions of Section 203 of the Delaware General Corporation Law (the “DGCL”), that may prohibit large stockholders, in particular those owning 15% or more of our outstanding common stock, from merging or combining with us.

These provisions of our organizational documents and the DGCL, alone or in combination with each other, may discourage transactions involving actual or potential changes of control, including transactions that otherwise could involve payment of a premium over prevailing market prices to holders of common stock, could limit the ability of stockholders to approve transactions that they may deem to be in their best interests, and could make it considerably more difficult for a potential acquirer to replace management.

As a public company in the United States, we are subject to the Sarbanes-Oxley Act. We have determined our disclosure controls and procedures and our internal control over financial reporting are effective. We can provide no assurance that we will, at all times, in the future be able to report that our internal controls over financial reporting are effective.

Companies that file reports with the SEC, including us, are subject to the requirements of Section 404 of the Sarbanes-Oxley Act of 2002 (“SOX”). Section 404 requires management to establish and maintain a system of internal control over financial reporting, and annual reports on Form 10-K filed under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), must contain a report from management assessing the effectiveness of our internal control over financial reporting. Ensuring we have adequate internal financial and accounting controls and procedures in place to produce accurate financial statements on a timely basis is a time-consuming effort that needs to be re-evaluated frequently. Failure on our part to have effective internal financial and accounting controls would cause our financial reporting to be unreliable, could have a material adverse effect on our business, operating results, and financial condition, and could cause the trading price of our common stock to fall.

Our ability to use our net operating loss carry-forwards and other tax attributes will be substantially limited by Section 382 of the U.S. Internal Revenue Code.

Under the federal income tax law, federal net operating losses incurred in 2018 and in future years may be carried forward indefinitely, but the deductibility of such federal net operating losses is limited. It is uncertain if and to what extent various states will conform to the federal tax law. In addition, Section 382 of the U.S. Internal Revenue Code of 1986, as amended, and corresponding provisions of state law, generally limit the ability of a corporation that undergoes an “ownership change” to utilize its net operating loss carry-forwards (“NOLs”) and certain other tax attributes against any taxable income in taxable periods after the ownership change. The amount of taxable income in each taxable year after the

43

Table of Contents

ownership change that may be offset by pre-change NOLs and certain other pre-change tax attributes is generally equal to the product of (a) the fair market value of the corporation’s outstanding shares (or, in the case of a foreign corporation, the fair market value of items treated as connected with the conduct of a trade or business in the United States) immediately prior to the ownership change and (b) the long-term tax exempt rate (i.e., a rate of interest established by the U.S. Internal Revenue Service that fluctuates from month to month). In general, an “ownership change” occurs whenever the percentage of the shares of a corporation owned, directly or indirectly, by “5-percent shareholders” (within the meaning of Section 382 of the Internal Revenue Code) increases by more than 50 percentage points over the lowest percentage of the shares of such corporation owned, directly or indirectly, by such “5-percent shareholders” at any time over the preceding three years.

Based on an analysis under Section 382 of the Internal Revenue Code (which subjects the amount of pre-change NOLs and certain other pre-change tax attributes that can be utilized to an annual limitation), we experienced ownership changes in 2009 and 2012, which substantially limit the future use of our pre-change NOLs and certain other pre-change tax attributes per year. In February 2017, we completed an equity financing for net proceeds of $24.8 million which triggered an additional ownership change under Section 382 that significantly impacted the availability of our tax attributes against future income. Further, due to the existence of a net unrealized built-in loss at the ownership change date, Section 382 further limits our ability to fully utilize the tax deductions associated with certain of our assets, including depreciation and amortization deductions recognized during the 60-month period following the ownership change ending in 2022. Although these deductions will occur in the post-change period, Section 382 treats the deductions as pre-change losses subject to the annual 382 limitation. As of December 31, 2020, we have excluded the NOLs and research and development credits that will expire as a result of the annual limitations. To the extent that we do not utilize our carry-forwards within the applicable statutory carry-forward periods, either because of Section 382 limitations or the lack of sufficient taxable income, the carry-forwards will also expire unused.

The 2017 tax reform law, as modified by 2020 tax legislation, and possible future changes in tax laws or regulations could adversely affect our business and financial condition.

On December 22, 2017, President Trump signed into law comprehensive tax legislation (the “Tax Cuts and Jobs Act”) that significantly revised the Internal Revenue Code of 1986, as amended (the “Code”). Future guidance from the U.S. Internal Revenue Service and other tax authorities with respect to the Tax Cuts and Jobs Act may affect us, and certain aspects of the Tax Cuts and Jobs Act could be repealed or modified in future legislation. For example, on March 27, 2020, the CARES Act was enacted, which includes changes to the tax provisions that benefit business entities and makes certain technical corrections to the Tax Cuts and Jobs Act. On June 29, 2020, California Assembly Bill 85 (AB 85) was signed into law, which suspends the use of California net operating losses and limits the use of California research tax credits for tax years beginning in 2020 and before 2023. Changes in corporate tax rates, the realization of net deferred tax assets relating to our U.S. operations, the taxation of foreign earnings, and the deductibility of expenses under the Tax Cuts and Jobs Act, the CARES Act, or future tax reform legislation could have a material impact on the value of our deferred tax assets, could result in significant one-time charges in the current or future taxable years, and could increase our future U.S. tax expense. The foregoing items, as well as any other future changes in tax laws, could have a material adverse effect on our business, cash flow, financial condition, or results of operations. In addition, it is uncertain if and to what extent various states will conform to the Tax Cuts and Jobs Act, the CARES Act, or any newly enacted federal tax legislation.

Shareholder and private lawsuits, and potential similar or related lawsuits, could result in substantial damages, divert management’s time and attention from our business, and have a material adverse effect on our results of operations.

Securities-related class action and shareholder derivative litigation has often been brought against companies, including many biotechnology companies, which experience volatility in the market price of their securities. This risk is especially relevant for us because biotechnology and biopharmaceutical companies often experience significant stock price volatility in connection with their product development programs.

It is possible that suits will be filed, or allegations received from stockholders, naming us and/or our officers and directors as defendants. These potential lawsuits are subject to inherent uncertainties, and the actual defense and disposition costs will depend upon many unknown factors. The outcome of these lawsuits is uncertain. We could be forced to expend significant resources in the defense of these suits and we may not prevail. In addition, we may incur substantial legal fees and costs in connection with these lawsuits. It is possible that we could, in the future, incur judgments or enter into

44

Table of Contents

settlements of claims for monetary damages. A decision adverse to our interests on these actions could result in the payment of substantial damages, or possibly fines, and could have a material adverse effect on our cash flow, results of operations and financial position.

Monitoring, initiating and defending against legal actions, including any currently pending litigation, are time-consuming for our management, are likely to be expensive and may detract from our ability to fully focus our internal resources on our business activities. The outcome of litigation is always uncertain, and in some cases could include judgments against us that require us to pay damages, enjoin us from certain activities, or otherwise affect our legal or contractual rights, which could have a significant adverse effect on our business. In addition, the inherent uncertainty of any future litigation could lead to increased volatility in our stock price and a decrease in the value of an investment in our common stock.

Item 1B.       Unresolved Staff Comments

None.

Item 2.   Properties

We currently lease one building that houses our corporate headquarters in Emeryville, California. The building lease expires in February 2023, and total net lease liability from January 2021 until expiration of the lease is $0.4 million. We believe that our facilities are adequate to meet our requirements for the near term.

Item 3.   Legal Proceedings

From time to time, we may be involved in litigation relating to claims arising out of our operations. We are not currently involved in any material legal proceedings. We may, however, be involved in material legal proceedings in the future. Such matters are subject to uncertainty and there can be no assurance that such legal proceedings will not have a material adverse effect on our business, results of operations, financial position or cash flows.

Market for Registrant’s Common Equity

Our common stock trades on The Nasdaq Global Market tier of the Nasdaq Stock Market LLC (“Nasdaq”) under the symbol “XOMA.” On March 5, 2021, there were 202 stockholders of record of our common stock, one of which was Cede & Co., a nominee for Depository Trust Company (“DTC”). All of the shares of our common stock held by brokerage firms, banks and other financial institutions as nominees for beneficial owners are deposited into participant accounts at DTC and are therefore considered to be held of record by Cede & Co. as one stockholder.

Dividend Policy

We have not paid dividends on our common stock. Holders of shares of our Series A preferred stock are entitled to receive, when and as declared by our Board of Directors, out of funds legally available for the payment of dividends, cumulative cash dividends at the rate of 8.625% of the $25.00 liquidation preference per year (equivalent to $2.15625 per year). We do not anticipate paying cash dividends on our common stock in the foreseeable future.

Item 7.   Management’s Discussion and Analysis of Financial Condition and Results of Operations

Overview

XOMA Corporation (“XOMA”), a Delaware corporation, is a biotech royalty aggregator. We have a sizable portfolio of economic rights to future potential milestone and royalty payments associated with partnered pre-commercial therapeutic candidates. Our portfolio was built through licensing our proprietary products and platforms from our legacy discovery and development business, combined with acquisitions of rights to future milestones and royalties that we have made since our royalty aggregator business model was implemented in 2017. Our drug royalty aggregator business is focused on early to mid-stage clinical assets primarily in Phase 1 and 2 with blockbuster potential licensed to large-cap partners. We expect that most of our future revenue will be based on payments we may receive for milestones and royalties related to these programs.

Significant Developments

Public Offering of Series A Preferred Shares

In December 2020, we sold 984,000 shares of 8.625% Series A cumulative, perpetual preferred stock (“Series A Preferred Stock”) at the price of $25.00 per share, through a public offering for aggregate gross proceeds of $24.6 million. Total offering costs of $2.0 million were offset against the proceeds from the sale of Series A Preferred Stock, for total net proceeds of $22.6 million. As of December 31, 2020, we held restricted cash of $2.1 million in a segregated account that may only be used to pay dividends on the Series A Preferred Stock. As of December 31, 2020, the current and non-current portion of restricted cash was $1.6 million and $0.5 million, respectively.

Royalty Purchase Agreements

Agenus Royalty Purchase Agreement

In November 2020, we earned $1.0 million pursuant to our Agenus Royalty Purchase Agreement upon the advancement of Merck’s MK-4830 into Phase 2 development.  

Bioasis Royalty Purchase Agreement

In November 2020, we entered into the Second Bioasis Royalty Purchase Agreement with Bioasis. Under the Second Bioasis Royalty Purchase Agreement, we purchased potential future milestone and other payments, and royalty rights from Bioasis for product candidates that are being developed pursuant to a research collaboration and license agreement between Bioasis and Chiesi. We paid Bioasis $1.2 million upon closing of the Second Bioasis Royalty Purchase Agreement for the purchased rights.  

License and Collaboration Agreements

Novartis

In October 2020, the first patient was dosed in Novartis International’s Phase 2 study of NIS793, an anti-TGFβ monoclonal antibody that we licensed to Novartis International, and we earned a $25.0 million milestone payment. As specified under the terms the Anti-TGFβ Antibody License Agreement, we received $17.7 million in cash and the remaining balance of $7.3 million was recognized as a reduction to our debt obligation to Novartis.

Takeda

In November 2020, the first patient was dosed in Takeda’s Phase 2 study of mezagitamab, and we earned a $2.0 million milestone payment from Takeda pursuant to our Takeda Collaboration Agreement.

Rezolute

47

Table of Contents

In December 2017, we entered into a license and common stock purchase agreement with Rezolute, which was amended on March 30, 2018 and further amended on January 7, 2019. The license agreement was amended to eliminate the requirement that equity securities be issued to us upon the closing of the Qualified Financing (as defined in the license agreement) and to replace it with a requirement that Rezolute: (1) make five cash payments to us totaling $8.5 million following the closing of a Qualified Financing on or before specified staggered future dates through September 2020 (the “Future Cash Payments”); and (2) provide for early payment of the Future Cash Payments (only until $8.5 million was reached) by making cash payments to us equal to 15% of the net proceeds of each future financing following the closing of the Qualified Financing, with such payments to be credited against any remaining unpaid Future Cash Payments in reverse order of their future payment date. The common stock purchase agreement was amended to remove certain provisions related to the issuance of equity to us in accordance with the new provisions regarding the Future Cash Payments in the license agreement.

On March 31, 2020, we and Rezolute further amended the license agreement to extend the payment schedule for the remaining $2.6 million in Future Cash Payments. The amendment to the payment terms was in response to Rezolute’s need to preserve cash as a result of the COVID-19 pandemic and was agreed to by us. The revised payment schedule did not impact the total amount due, but instead, spread the $2.6 million into seven quarterly payments to be paid through September 30, 2021. The amended license agreement required that in the event Rezolute completed a Qualified Financing at any time between March 31, 2020 and the date of the final payment, Rezolute would pay all amounts outstanding within fifteen days following the closing of the Qualified Financing.

In the first quarter of 2020, we received the scheduled $0.4 million Future Cash Payment from Rezolute. We evaluated Rezolute’s cash position as of March 31, 2020, including the estimated impact of the COVID-19 pandemic, and determined payments scheduled beyond September 30, 2020 were unlikely to be collected unless Rezolute was able to obtain additional funding, which had not occurred as of March 31, 2020. Therefore, for the three months ended March 31, 2020, we recorded $1.4 million in bad debt expense related to the Future Cash Payments. We received the scheduled $0.4 million and $0.4 million Future Cash Payments from Rezolute in the second and third quarters of 2020, respectively.

On October 9, 2020, Rezolute completed a private placement of its equity securities with gross proceeds of $41.0 million, which was considered a Qualified Financing event under the Third Amendment. The Qualified Financing resulted in acceleration of the remaining receivables of $1.4 million due from Rezolute, and we received the entire amount in October 2020.

Zydus

In March 2020, we entered into a license agreement (the “Zydus Agreement”) with Cadila Healthcare Limited (“Zydus”) under which we granted Zydus an exclusive royalty-bearing license to our anti-interleukin-2 (“IL-2”) monoclonal antibodies, including mAb19, for Zydus to develop and commercialize drug candidates in India, Brazil, Mexico and certain other emerging markets. We retain rights in all other territories, subject to a Zydus right of first negotiation. Under the terms of the Zydus Agreement, Zydus is responsible for the development and commercialization of IL-2 based immuno-oncology drug candidates. XOMA is entitled to receive up to $0.5 million in development and regulatory milestone payments, up to $23.5 million in commercial milestone payments, and mid single-digit to low teens royalties from Zydus. We are also eligible to share out-licensing revenue received by Zydus should Zydus (sub)license to third parties, which share is tiered based on clinical trial stage and ranges from a low to mid double-digit percentage rate.

COVID-19

The COVID-19 pandemic continues to pose risks to our business as clinical trials industry-wide have slowed. Our business is dependent on the continued development and commercialization efforts of our licensees and our royalty agreement counterparties and their licensees. We have been monitoring and continue to monitor our portfolio programs for potential delays in underlying research programs and elections of our partners to continue or cease development. Delays in clinical trials and underlying research programs may lead to delayed revenue from milestones from our licensees and royalty agreement counterparties or, if certain research programs are discontinued, we may recognize impairment charges for our royalty receivables. COVID-19, the related variants, and the timing of vaccine distribution may impact our underlying programs in a variety of ways which are unknown in length and scope at this time.

Critical Accounting Estimates

The accompanying discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements and the related disclosures, which have been prepared in accordance with generally accepted accounting principles in the United States. The preparation of these consolidated financial statements requires us to make estimates, assumptions and judgments that affect the reported amounts in our consolidated financial statements and accompanying notes. On an ongoing basis, we evaluate our estimates, assumptions and judgments described below that have the greatest potential impact on our consolidated financial statements, including those related to legal contingencies, revenue recognized under units-of-revenue method and stock-based compensation. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Accounting assumptions and estimates are inherently uncertain and actual results may differ materially from these estimates under different assumptions or conditions.

While our significant accounting policies are more fully described in Note 2 to the consolidated financial statements, we believe the following policies to be the most critical to an understanding of our financial condition and results of operations because they require us to make estimates, assumptions and judgments about matters that are inherently uncertain.

Revenue Recognition

We recognize revenue from all contracts with customers according to Accounting Standards Codification (“ASC”) Topic 606, Revenue from Contracts with Customers ("ASC 606"), except for contracts that are within the scope of other standards, such as leases, insurance, collaboration arrangements and financial instruments. We recognize revenue when our customer obtains control of promised goods or services, in an amount that reflects the consideration which we expect to receive in exchange for those goods or services.

We have certain license arrangements in the scope of ASC 606. The terms of these agreements may contain multiple performance obligations, which primarily include transfer of our licenses. Prior to recognizing revenue, we make estimates of the transaction price, including variable consideration that is subject to a constraint. Amounts of variable consideration are included in the transaction price to the extent that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur and when the uncertainty associated with the variable consideration is subsequently resolved. Variable consideration may include payments based upon the achievement of specified milestones, and royalty payments based on product sales derived from the license agreements. The royalty payments will be recognized as revenue when the related sales occur, as far as there are no unsatisfied performance obligations remaining. If there are multiple distinct performance obligations, we allocate the transaction price to each distinct performance obligation based on its relative standalone selling price. All licenses we grant to customers are unique, as each uses a specific technology of XOMA or is geared towards a specific unique product candidate. Thus, there is no observable evidence of standalone selling price for the licenses. The standalone selling price is generally determined using a valuation approach based on discounted cash flow analysis. For licenses that are bundled with other promises, we utilize judgement to assess the nature of the combined performance obligation to determine whether the combined performance obligation is satisfied over time or at a point in time. Under our license agreements, the nature of the combined performance obligation is the granting of licenses to the customers. As such, we recognize revenue related to the combined performance obligation upon transfer of the license to the customers or completion of the transfer of related materials and services (i.e., point in time).

Sale of Future Revenue Streams

We have sold our rights to receive certain milestones and royalties on product sales. In the circumstance where we have sold our rights to future milestones and royalties under a license agreement and also maintain limited continuing involvement in the arrangement (but not significant continuing involvement in the generation of the cash flows that are due to the purchaser), we defer recognition of the proceeds we received for the sale of milestone or royalty streams and recognize such unearned revenue as revenue under the units-of-revenue method over the life of the underlying license agreement. Under the units-of-revenue method, amortization for a reporting period is calculated by computing a ratio of

49

Table of Contents

the proceeds received from the purchaser to the total payments expected to be made to the purchaser over the term of the agreement, and then applying that ratio to the period’s cash payment.

Estimating the total payments expected to be received by the purchaser over the term of such arrangements requires management to use subjective estimates and assumptions. Changes to our estimate of the payments expected to be made to the purchaser over the term of such arrangements could have a material effect on the amount of revenues recognized in any particular period.

Stock-based Compensation

Stock-based compensation expense for stock options and other stock awards is estimated at the grant date based on the award’s fair value-based measurement. The valuation of stock-based compensation awards is determined at the date of grant using the Black-Scholes option pricing model (the “Black-Scholes Model”). This model requires highly complex and subjective inputs, such as the expected term of the option and expected volatility. These inputs are subjective and generally require significant analysis and judgment to develop. Our current estimate of volatility is based on the historical volatility of our stock price. To the extent volatility in our stock price increases in the future, our estimates of the fair value of options granted in the future could increase, thereby increasing stock-based compensation cost recognized in future periods. To establish an estimate of expected term, we consider the vesting period and contractual period of the award and our historical experience of stock option exercises, post-vesting cancellations and volatility. The risk-free rate is based on the yield available on United States Treasury zero-coupon issues. Forfeitures are recognized as they occur.

We review our valuation assumptions quarterly and, as a result, we likely will update our valuation assumptions used to value stock-based awards granted in future periods utilizing current data. In the future, as additional empirical evidence regarding these input estimates becomes available, we may change or refine our approach of deriving these input estimates. These changes could impact our fair value-based measurement of stock options granted in the future. Changes in the fair value-based measurement of stock awards could materially impact our operating results.

For our stock options and service-based awards, we recognize compensation expense on a straight-line basis over the award’s vesting period.

Purchase of Rights to Future Milestones and Royalties

We have purchased rights to receive a portion of certain future developmental, regulatory and commercial sales milestones, and royalties on sales of products currently in clinical development. We acquired such rights from various entities and recorded the amount paid for these rights as long-term royalty receivables. We have accounted for the purchased rights as a financial asset in accordance with ASC 310, Receivables.

We account for milestone and royalty rights related to developmental pipeline products on a non-accrual basis using the cost recovery method. These developmental pipeline products are non-commercialized, non-approved products that require FDA or other regulatory approval, and thus have uncertain cash flows. The related receivable balance is classified as noncurrent since no payments are probable to be received in the near term. Under the cost recovery method, any milestone or royalty received is recorded as a direct reduction of the recorded receivable balance. When the recorded receivable balance has been fully collected, any additional amounts collected are recognized as revenue.

We review public information on clinical trials, press releases and updates from our partners regularly to identify any impairment indicators or changes in expected recoverability of the long-term receivable asset. If expected future cash flows discounted to the current period are less than the carrying value of the asset, we will record impairment. The impairment will be recognized by reducing the financial asset to an amount that represents the present value of the most recent estimate of cash flows. No impairment was recorded as of December 31, 2020.

Revenue from Contracts with Customers

Revenue from contracts with customers includes upfront fees, milestone payments and royalties related to the out-licensing of our product candidates and technologies. The primary components of revenue from contracts with customers in 2020 was $25.0 million in milestone revenue earned under our Anti-TGFβ Antibody License Agreement with Novartis International and $2.0 million earned under our collaboration agreement with Takeda. The primary components of revenue from contracts with customers in 2019 was $14.0 million recognized under our license agreement and common stock purchase agreement with Rezolute and $2.5 million in revenue earned from a one-time payment under our license agreement with Janssen.

The generation of future revenues related to licenses, milestones, and royalties is dependent on the achievement of milestones or product sales by our existing licensees. Due to the anticipated impact of COVID-19 on clinical trial activities of our licensees, potential milestone payments may be delayed.

Revenue recognized under units-of-revenue method

Revenues recognized under the units-of-revenue method include the amortization of unearned revenue from the sale of royalty interests to HealthCare Royalty Partners II, L.P (“HCRP”) in 2016. The increase in 2020 compared with 2019 was due to increased sales of products underlying the agreements with HCRP.

The generation of future revenues related to licenses, milestones, and royalties is dependent on the achievement of milestones or product sales by our existing licensees. Milestone payments earned in 2020 are not indicative of anticipated milestones in future periods.

Research and Development Expenses

Research and development (“R&D”) expenses were $0.2 million in 2020, compared with $1.3 million in 2019. The decrease of $1.1 million in 2020, as compared with 2019, was primarily due to a $0.5 million decrease in salary and related expenses as a result of a shift in employee duties that led to a recategorization of an employee from R&D to a general and administrative (“G&A”) department and a $0.5 million decrease in license fee expenses.

We do not expect to incur substantial R&D expenses in 2021 due to the focus on our royalty aggregator business model.

General and Administrative Expenses

G&A expenses include salaries and related personnel costs, facilities costs and professional fees. In 2020, G&A expenses were $16.8 million compared with $21.0 million in 2019.

The decrease of $4.2 million in 2020 as compared with 2019 was primarily due to a $3.9 million decrease in facilities costs due to the termination of our legacy leases and a $1.2 million decrease in salary and related expenses due

51

Table of Contents

to a 2019 separation agreement. These decreases were partially offset by a $1.4 million increase in consulting and legal costs.

To support our royalty aggregator business model, we engage third parties to assist in our evaluation of potential acquisitions of milestone and royalty streams. While we expect our personnel related costs to be comparable in 2021 with 2020, consulting expenses may increase in response to an increase in the volume of acquisition targets evaluated or completed.

The decrease in interest expense compared with 2019 is primarily due to lower interest rates and decreased loan balances. In October 2020, in connection with the achievement of a clinical development milestone, $7.3 million of the $25.0 million milestone payment received was recognized as a reduction to the Novartis debt obligation.

We expect our interest expense to decrease in 2021 due to the reduction in our outstanding loan balances. If market interest rates increase in the near term, or if we elect to obtain additional financing, our interest expense may increase.

During the years ended December 31, 2020 and 2019, we remeasured the fair value of the equity securities and recognized gains of $1.0 million and $0.3 million, respectively.

The decrease in investment income for the year ended December 31, 2020 as compared to the same period of 2019 is due to lower rates of return on our cash deposits.

Table of Contents

We were party to four sublease agreements in 2019. As a result of the termination of our legacy leases in December 2019, we are no longer party to any subleases, resulting in no sublease income for the year ended December 31, 2020 as compared to the same period of 2019.

Total other income, net for 2020 decreased by $2.6 million as compared to 2019 primarily due to the $3.0 million decrease in sublease income.

Provision for Income Taxes

We recorded a $1.5 million income tax benefit for the year ended December 31, 2020 as a result of the CARES Act, which was enacted on March 27, 2020. The CARES Act permits us to carry back losses from 2018 to offset income in 2017 resulting in an income tax receivable. We had no provision for income tax for the year ended December 31, 2019 since we incurred net operating losses.

We continue to maintain a full valuation allowance against our remaining net deferred tax assets. We had a total of $5.9 million of gross unrecognized tax benefits, none of which would affect the effective tax rate upon realization. We do not expect our unrecognized tax benefits to change significantly over the next twelve months.

Net cash used in operating activities in 2019 of $0.3 million was primarily due to the $2.0 million net loss incurred.

Cash Used in Investing Activities

Net cash used in investing activities for the year ended December 31, 2020 of $0.2 million was due to the purchase of milestone and royalty rights of $1.2 million in connection with the Second Bioasis Royalty Purchase Agreement in November 2020, partially offset by $1.0 million milestone payment received in connection with the Agenus Royalty Purchase Agreement.

Net cash used in investing activities for the year ended December 31, 2019 of $19.3 million was due to the purchases of milestone and royalty rights of $19.3 million in connection with the Bioasis Royalty Purchase Agreement

executed in February 2019, the Aronora Royalty Purchase Agreement executed in April 2019, and the Palo Royalty Purchase Agreement executed in September 2019.

Cash Provided by Financing Activities

Net cash provided by financing activities for the year ended December 31, 2020 of $19.8 million was primarily due to the receipt of net cash proceeds of $22.6 million from the public offering of Series A Preferred Stock and $2.4 million net cash provided from the exercise of stock options after related tax payments, partially offset by $5.3 million cash used in the principal payments of debt.

Net cash provided by financing activities for the year ended December 31, 2019 of $30.5 million was primarily related to the sale of common stock issued under the 2019 Rights Offering for total net proceeds of $21.9 million and proceeds received under the SVB loan agreement of $9.5 million.

Public Offering of Series A Preferred Shares

In December 2020, we sold 984,000 shares of 8.625% Series A cumulative, perpetual preferred stock at the price of $25.00 per share, through a public offering for aggregate gross proceeds of $24.6 million. Total offering costs of $2.0 million were offset against the proceeds from the sale of Series A Preferred Stock, for net proceeds of $22.6 million. Holders of our Series A preferred stock are entitled to receive, when and as declared by our Board of Directors, out of funds legally available for the payment of dividends, cumulative cash dividends at the rate of 8.625% of the $25.00 liquidation preference per year (equivalent to $2.15625 per year). Dividends on the Series A preferred stock will accumulate and be cumulative from, and including, the date of original issue by us of the Series A preferred stock. Dividends will be payable in arrears on or about the 15th day of January, April, July and October beginning on or about April 15, 2021. As of December 31, 2020, we held restricted cash of $2.1 million in a segregated account that may only be used to pay dividends on the Series A Preferred Stock. As of December 31, 2020, the current and non-current portion of restricted cash was $1.6 million and $0.5 million, respectively.

Rights Offering 2019

In November 2019, we initiated a rights offering to raise $22.0 million through the distribution of subscription rights to holders of our common stock and Series X and Series Y preferred stock. In December 2019, we sold 1,000,000 shares of our common stock at the subscription price of $22.00 per share for aggregate gross proceeds of $22.0 million. Total offering costs of $0.2 million were offset against the proceeds from the sale of common stock, for total net proceeds of $21.8 million.

Silicon Valley Bank Loan Agreement

Under our Loan Agreement with SVB, upon our request, SVB made advances available to us up to $20.0 million. In March 2019, we and SVB amended the Loan Agreement to extend the draw period from March 31, 2019 to March 31, 2020. In connection with the amendment, we issued a second warrant to SVB which is exercisable in whole or in part for up to an aggregate of 4,845 shares of common stock with an exercise price of $14.71 per share. The warrant may be exercised on a cashless basis and is exercisable within 10 years from the date of issuance or upon the consummation of certain acquisitions of XOMA. As of December 31, 2020, we had an outstanding principal balance of $12.2 million under the Loan Agreement, of which $8.1 million was classified as current portion of long-term debt.

2018 ATM Agreement

In December 2018, we entered into an At The Market Issuance Sales Agreement (the “2018 ATM Agreement”) with H.C. Wainwright & Co., LLC (“HCW”), under which we may offer and sell from time to time at our sole discretion shares of our common stock through HCW as our sales agent, in an aggregate amount not to exceed $30.0 million. HCW may sell the shares by any method permitted by law deemed to be an “at the market” offering as defined in Rule 415 of the Securities Act, and will use its commercially reasonable efforts consistent with its normal trading and sales practices to sell the shares up to the amount specified. We are required to pay HCW a commission of up to 3% of the gross proceeds of any shares of common stock sold under the 2018 ATM Agreement. We have not sold any shares of common stock under the 2018 ATM Agreement.

We have incurred significant operating losses since our inception and have an accumulated deficit of $1.2 billion at December 31, 2020. As of December 31, 2020, we had $84.2 million and $2.1 million in unrestricted and restricted cash, respectively, which will enable us to maintain our operations for a period of at least 12 months following the filing date of this report. As of December 31, 2020, the current and non-current portion of restricted cash was $1.6 million and $0.5 million, respectively.

We have taken and continue to take steps to manage our resources by reducing and/or deferring certain discretionary expenditures to mitigate the adverse impact of the COVID-19 pandemic. Future impacts of COVID-19, related variants, and vaccine distribution may require further actions to improve our cash position, which may include reducing or delaying acquisitions of additional royalty and milestone rights or obtaining additional funds through debt arrangements, the 2018 ATM Agreement, or other equity issuances. Our ability to raise additional capital in the equity and debt markets, should we choose to do so, is dependent on a number of factors, including, but not limited to, the market demand for our common stock, which itself is subject to a number of development and business risks and uncertainties, our creditworthiness and the uncertainty that we would be able to raise such additional capital at a price or on terms that are favorable to us. In addition, our ability to raise additional funds may be adversely impacted by deteriorating global economic conditions and the recent disruptions to and volatility in the credit and financial markets in the United States and worldwide resulting from the ongoing COVID-19 pandemic.

Commitments and Contingencies

Although operations are influenced by general economic conditions, we do not believe inflation had a material impact on financial results for the periods presented. We believe that we are not dependent on materials or other resources that would be significantly impacted by inflation or changing economic conditions in the foreseeable future.

Collaborative Agreements, Royalties and Milestone Payments

We have committed to make potential future milestone payments and legal fees to third parties as part of licensing and development programs. Payments under these agreements become due and payable only upon the achievement of certain developmental, regulatory and commercial milestones by our licensees. Because it is uncertain if and when these milestones will be achieved, such contingencies, aggregating up to $7.6 million (assuming one product per contract meets all milestones) have not been recorded on our consolidated balance sheet as of December 31, 2020. We are unable to

55

Table of Contents

determine precisely when and if our payment obligations under the agreements will become due as these obligations are based on milestone events, the achievement of which is subject to a significant number of risks and uncertainties.

Lease Agreements

In December 2019, we terminated two of our operating leases in Berkeley, California and were fully released from any further payment obligations. We continue to lease one administrative facility in Emeryville, California under an operating lease expiring in February 2023. The lease requires us to pay taxes, insurance, maintenance and minimum lease payments.

Recent Accounting Pronouncements

In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. ASU 2016-13 replaced the incurred loss impairment methodology under current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. ASU 2016-13 requires use of a forward-looking expected credit loss model for accounts receivables, loans, and other financial instruments. Adoption of the standard requires using a modified retrospective approach through a cumulative-effect adjustment to retained earnings as of the effective date to align existing credit loss methodology with the new standard. Subsequent to issuing ASU 2016-13, the FASB issued ASU 2018-19, Codification Improvements to Topic 326, Financial Instruments – Credit Losses, or ASU 2018-19, for the purpose of clarifying certain aspects of ASU 2016-13. In May 2019, the FASB issued ASU 2019-05, Financial Instruments – Credit Losses (Topic 326): Targeted Transition Relief, or ASU 2019-05, to provide entities with more flexibility in applying the fair value option on adoption of the credit impairment standard. ASU 2018-19 and ASU 2019-05 have the same effective date and transition requirements as ASU 2016-13. ASU 2016-13 will be effective for all entities except public companies that are not smaller reporting companies for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years, using a modified retrospective approach. Early adoption is permitted. We plan to adopt ASU 2016-13 and related updates as of January 1, 2023. We are evaluating the impact of adopting this new accounting guidance on our consolidated financial statements.

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820) (“ASU 2018-13”), which modifies, removes and adds certain disclosure requirements on fair value measurements based on the FASB Concepts Statement, Conceptual Framework for Financial Reporting—Chapter 8: Notes to Financial Statements. The ASU is effective for our interim and annual reporting periods during the year ending December 31, 2020, and all annual and interim reporting period thereafter. The amendments on changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements and the narrative description of measurement uncertainty should be applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. All other amendments should be applied retrospectively to all periods presented upon their effective date. Early adoption is permitted upon issuance of ASU 2018-13. An entity is permitted to early adopt any removed or modified disclosures upon issuance of ASU 2018-13 and delay adoption of the additional disclosures until their effective date. We early adopted the guidance related to removal of disclosures upon issuance of this ASU and adopted the deferred provisions as permitted under the ASU in the first quarter of 2020. The adoption of ASU 2018-13 did not have a material impact on our consolidated financial statements.

In November 2018, the FASB issued ASU 2018-18, Collaborative Arrangements (Topic 808) “Clarifying the Interaction between Topic 808 and Topic 606,” which requires transactions in collaborative arrangements to be accounted for under ASC 606 if the counterparty is a customer for a good or service that is a distinct unit of account. The new standard also precludes an entity from presenting consideration from transactions with a collaborator that is not a customer together with revenue recognized from contracts with customers. The ASU is effective for our interim and annual reporting periods during the year ending December 31, 2020, and all annual and interim reporting period thereafter. Early adoption is permitted, but no earlier than an entity’s adoption date of Topic 606. This ASU requires retrospective adoption to the date we adopted ASC 606, January 1, 2018, by recognizing a cumulative-effect adjustment to the opening balance of retained earnings of the earliest annual period presented. We may elect to apply the ASU retrospectively either to all contracts or

56

Table of Contents

only to contracts that are not completed at the date it initially applied ASC 606. We adopted ASU 2018-18 as of January 1, 2020. The adoption of ASU 2018-18 did not have a material impact on our consolidated financial statements.

In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. The amendments in ASU 2019-12 are intended to simplify various aspects related to accounting for income taxes. ASU 2019-12 removes certain exceptions to the general principles in Topic 740 and also clarifies and amends existing guidance to improve consistent application. ASU 2019-12 is effective for us beginning January 1, 2021. We are evaluating the impact of ASU 2019-12, but do not expect adopting this new accounting guidance will have a material impact on our consolidated financial statements.

In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. These amendments provide temporary optional guidance to ease the potential burden in accounting for reference rate reform. The ASU provides optional expedients and exceptions for applying generally accepted accounting principles to contract modifications and hedging relationships, subject to meeting certain criteria, that reference LIBOR or another reference rate expected to be discontinued. It is intended to help stakeholders during the global market-wide reference rate transition period. The guidance is effective for all entities as of March 12, 2020 through December 31, 2022 and can be adopted as of any date from the beginning of an interim period that includes or is subsequent to March 12, 2020. We are evaluating the impact of adopting this new accounting guidance on our consolidated financial statements.

In August 2020, the FASB issued ASU 2020-06, Debt – Debt with Conversion and Other Options (Subtopic 470-20) and Derivative and Hedging – Contracts in Entity’s Own Equity (Subtopic 815-40). This ASU reduces the number of accounting models for convertible debt instruments and convertible preferred stock and amends the guidance for the derivatives scope exception for contracts in an entity’s own equity to reduce form-over-substance-based accounting conclusion. In addition, this ASU improves and amends the related EPS guidance. These amendments are effective for us for fiscal years beginning after December 15, 2023, including interim period within those fiscal years. Early adoption is permitted, but no earlier than fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. Adoption is either a modified retrospective method or a fully retrospective method of transition. We are currently evaluating the impacts of the provisions of ASU 2020-06 and we do not expect this ASU to have a material impact on our consolidated financial statements.

Item 9A.       Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Under the supervision and with the participation of our management, including our Chief Executive Officer and our Senior Vice President, Finance and Chief Financial Officer, we conducted an evaluation of our disclosure controls and procedures, as such term is defined under Rule 13a-15 promulgated under the Securities Exchange Act of 1934, as amended, as of the end of the period covered by this report. Our disclosure controls and procedures are intended to ensure that the information we are required to disclose in the reports that we file or submit under the Securities Exchange Act of 1934 is (i) recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms and (ii) accumulated and communicated to our management, including the Chief Executive Officer and Senior Vice President, Finance and Chief Financial Officer, as the principal executive and financial officers, respectively, to allow timely decisions regarding required disclosures. Based on this evaluation, our Chief Executive Officer and our Senior Vice President, Finance and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of the end of the period covered by this report.

Management’s Report on Internal Control over Financial Reporting

Management, including our Chief Executive Officer and our Senior Vice President, Finance and Chief Financial Officer, is responsible for establishing and maintaining adequate internal control over financial reporting (as such term is defined in Exchange Act Rules 13a-15(f)). The Company’s internal control system was designed to provide reasonable assurance to the Company’s management and board of directors regarding the preparation and fair presentation of published financial statements in accordance with accounting principles generally accepted in the United States.

Management assessed the effectiveness of our internal control over financial reporting as of December 31, 2020. In making this assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”) in Internal Control—Integrated Framework (2013 Framework). Based on our assessment we believe that, as of December 31, 2020, our internal control over financial reporting is effective based on those criteria.

This Annual Report does not include an attestation report by our registered public accounting firm regarding internal control over financial reporting. Management's report is not subject to attestation by our registered public accounting firm under Section 404(b) of the Sarbanes-Oxley Act pursuant to the rules established by the Securities and Exchange Commission, which permit us to provide only our management report in this Annual Report.

Changes in Internal Control over Financial Reporting

There have been no changes in our internal controls over financial reporting as defined in Rule 13a-15(f) under the Exchange Act during our most recent fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal controls over financial reporting. While COVID-19 has resulted in our staff operating remotely, our established internal control structure is not impacted. As we continue to monitor and adapt to the changing environment due to COVID-19 and the related possibility of a cybersecurity impact, including a security breach or cyber-attack, we will continue to evaluate our internal controls over financial reporting.

Item 9B.       Other Information

On March 10, 2021, we amended the 2018 ATM Agreement with HCW to increase the aggregate amount of shares of our common stock that we could sell through HCW as our sales agent to $50.0 million.

Stockholder Recommendation of Nominees for Director

There have been no material changes to the procedures by which stockholders may recommend nominees to the board of directors since XOMA filed its proxy statement related to the 2020 annual meeting of stockholders with the SEC on April 9, 2020. The Nominating & Governance Committee’s charter provides that the committee will, on behalf of the Board, review letters from stockholders regarding the Company’s annual meeting and governance process. Beyond this, the committee has no formal policy regarding consideration of director candidates recommended by stockholders, in large part because the Company has never received from any of its stockholders a recommendation of a director nominee with reasonably adequate qualifications. The need for a more formal policy was considered and determined to be unnecessary by the committee. The committee will consider candidates recommended by stockholders, and a stockholder wishing to submit a recommendation should send a letter to the Secretary of the Company at 2200 Powell Street, Suite 310, Emeryville, California 94608. The mailing envelope must contain a clear notation indicating that the enclosed letter is a “Director Nominee Recommendation.” The letter must identify the author as a stockholder and provide a complete listing of the candidate’s qualifications to serve on the Board, the candidate’s current principal occupation, most recent five-year employment history and current directorships and a statement that the proposed nominee has consented to the nomination, as well as contact information for both the candidate and the author of the letter. Stockholders may also nominate candidates who are not first recommended to the Nominating & Governance Committee by following procedures set forth in our by-laws. The Nominating and Corporate Governance Committee does not intend to alter the manner in which it evaluates candidates, including the minimum criteria set forth above, based on whether or not the candidate was recommended by a stockholder.

To be considered by the Nominating & Governance Committee, a director nominee must have experience as a board member or senior officer of a company, have a strong financial background, be a leading participant in a field relevant to the Company’s business or have achieved national prominence in a relevant field as a faculty member, professional or government official. In addition to these minimum requirements, the committee seeks director candidates based on a number of qualifications, including their independence, knowledge, judgment, leadership skills, education, experience, financial literacy, standing in the community and ability to foster a diversity of backgrounds and views and complement the Board’s existing strengths. The Board believes that diversity with respect to all of these factors, including diversity of personal background, business and professional background, perspective, experience and other characteristics, such as gender, gender identity, ethnicity, sexual orientation and age, is an important consideration in appropriate Board composition.

The Board and the Nominating & Governance Committee begins the process of identifying and evaluating director nominees by seeking recommendations from a wide variety of contacts, which may include current executive officers and directors and industry, academic and community leaders. The Board or the committee may retain search firms to identify and screen candidates, conduct reference checks, prepare biographies for review by the committee and the Board and assist in setting up interviews. The Nominating & Governance Committee, and one or more of the Company’s other directors, interview candidates, and the committee selects and recommends to the full Board nominees that best suit the Company’s needs.

Narrative to Summary Compensation Table

Base Salary

Our Compensation Committee recognizes the importance of base salary as an element of compensation that helps to attract and retain our executive officers. We provide base salary as a fixed source of cash compensation to recognize each named executive officer’s day-to-day responsibilities, which is designed to provide an appropriate and competitive base level of current cash income for the named executive officers. The 2020 annual base salary of Mr. Burns was determined and approved by the Compensation Committee in February 2020. The annual base salary of Mr. Neal was recommended by the Compensation Committee and approved by the Board. The 2020 base salaries were as follows:

The amount of cash actually paid to Mr. Burns was based on the Company meeting the 2020 corporate objectives previously approved by the Board.

Equity Compensation

We believe that our ability to grant equity-based awards is a valuable and necessary compensation tool that aligns the long-term financial interests of our executive officers with the financial interests of our stockholders. In addition, we believe that our ability to grant equity-based awards helps us to attract, retain and motivate executive officers, and encourages them to devote their best efforts to our business and financial success. Vesting of equity awards is generally tied to continuous service with us and serves as an additional retention measure. Our executive officers generally are awarded an initial new hire grant upon commencement of employment, as well as annual grants.

Each of our named executive officers currently holds stock options under our Amended and Restated 2010 Long Term Incentive Stock Award Plan, or the 2010 Plan, that were granted subject to the general terms thereof and the applicable forms of stock option agreement thereunder. The specific vesting terms of each named executive officer’s stock options are described below under “Outstanding Equity Awards as of December 31, 2020.”

We currently grant all equity awards pursuant to the 2010 Plan. All options are granted with a per share exercise price equal to no less than the fair market value of a share of our Common Stock on the date of the grant, and generally vest on a monthly basis over 36 months, subject to the continued service with us through each vesting date. All options have a maximum term of up to 10 years from the date of grant, subject to earlier expiration following the cessation of an executive officer’s continuous service with us. Option vesting is subject to acceleration as described below under “Certain Other Payments upon a Change of Control.” Options generally remain exercisable for three months following an executive officer’s termination, except in the event of a termination for cause or due to disability or death.

In February 2021, Mr. Neal and Mr. Burns were granted stock options to purchase 60,268 shares and 20,055 shares of Common Stock, respectively, under our 2010 Plan, which vest monthly over three years, subject to each executive’s continued service to us on each applicable vesting date. In March 2020, the Compensation Committee and Board granted to each of Mr. Neal and Mr. Burns stock options to purchase 66,200 shares, and 22,000 shares of Common Stock, respectively, under our 2010 Plan, which vest monthly over three years subject to each executive’s continued service to us on each applicable vesting date.

Certain Other Payments upon a Change of Control

Named Executive Officers. Each of our named executive officers has entered into a change of control severance agreement. Under each change of control agreement, if the executive officer’s employment is involuntarily terminated by the Company without cause or if the executive officer resigns with good reason, in either case, within two months prior to signing an agreement for a change of control or within 24 months after a change of control, then the Company may be required to make certain payments and/or provide certain benefits to certain executive officers, as described below.

Change of Control. Under each change of control agreement, a “change of control” is defined as the occurrence of any of the following events: (i) a merger, amalgamation or acquisition in which the Company is not the surviving or continuing entity, except for a transaction the principal purpose of which is to change the jurisdiction of the Company’s organization; (ii) the sale, transfer or other disposition of all or substantially all of the assets of the Company; (iii) any

66

Table of Contents

other reorganization or business combination in which 50% or more of the Company’s outstanding voting securities are transferred to different holders in a single transaction or series of related transactions; (iv) any approval by the stockholders of the Company of a plan of complete liquidation of the Company; (v) any “person” (as such term is used in Sections 13(d) and 14(d) of the Exchange Act becoming the “beneficial owner” (as defined in Rule 13d-3 under said Act), directly or indirectly, of securities of the Company representing more than 50% of the total voting power represented by the Company’s then-outstanding voting securities; or (vi) a change in the composition of the Board, as a result of which fewer than a majority of the directors are incumbent directors.

Vesting of Options. If a named executive officer’s employment is involuntarily terminated within two months prior to signing an agreement for a change of control or within 12 months after a change of control, the exercisability of all time-based equity awards granted to such executive officer by the Company shall automatically be accelerated so that all such options may be exercised immediately upon such involuntary termination for any or all of the shares subject thereto and the post-termination exercise period shall be extended to 60 months or the remainder of the maximum term of the options (or such shorter period of time to avoid the application of Section 409A of the Code). Additionally, if a named executive officer’s employment is involuntarily terminated within two months prior to signing an agreement for a change of control or within 12 months after a change of control, the exercisability of a pro-rated number of performance awards held by such executive officer shall be accelerated, based on the number of days that have elapsed during the performance period and the deemed level of achievement of the performance goals as determined by the Company’s board of directors. The awards shall continue to be subject to all other terms and conditions of the Company’s option plans and the applicable option agreements between the employee and the Company.

Outplacement Program. If a named executive officer’s employment is involuntarily terminated within two months prior to signing an agreement for a change of control or within 24 months after a change of control, the named executive officer will immediately become entitled to participate in a twelve-month executive outplacement program provided by an executive outplacement service, at the Company’s expense not to exceed $15,000.

 

Cash Severance. If a named executive officer’s employment is involuntarily terminated within two months prior to signing an agreement for a change of control or within 12 months after a change of control, then the executive officer shall be entitled to receive a cash severance payment equal to the sum of (A) an amount equal to 1.5 times (or, in the case of the Chief Executive Officer, two times) the executive officer’s annual base salary as in effect immediately prior to the involuntary termination plus (B) an amount equal to 1.5 times (or, in the case of the Chief Executive Officer, two times) the named executive officer’s target bonus as in effect for the fiscal year in which the involuntary termination occurs.

Health and Other Benefits. If a named executive officer’s employment is involuntarily terminated within two months prior to signing an agreement for a change of control or 12 months after a change of control, then for a period of 18 months (or, in the case of the chief executive officer, 24 months) following such termination, the Company shall make available and pay for the full cost of the coverage (plus an additional amount to pay for the taxes on such payments, if any, plus any taxes on such additional amount) of the executive officer and his or her spouse and eligible dependents under any group health plans of the Company on the date of such termination of employment at the same level of health (i.e., medical, vision and dental) coverage and benefits as in effect for the executive officer or such covered dependents on the date immediately preceding the date of his or her termination, provided that, in each case, the executive officer elects such continuation coverage, or, if necessary for the Company to avoid a tax penalty, a cash payment in lieu of such continuation coverage

The change of control agreements provide that the legacy “golden parachute” excise tax gross-up provision, pursuant to which the Company will make a gross-up payment necessary to fully satisfy any excise taxes on the executive officer as a result of payments under the change of control agreement or otherwise, expired on February 10, 2019, and have been replaced with a “better after-tax” provision, pursuant to which payments to the executive officer are either reduced or paid in full, whichever results in a greater economic benefit to the executive officer (after calculation of all taxes on such payments).

Director Compensation

The primary objectives of the Company’s director compensation program are to enable the Company to attract, motivate and retain outstanding individuals and align their success with that of the Company’s stockholders through the creation of stockholder value. We attract and retain directors by benchmarking against companies in our industry of similar size to ensure that our director compensation packages remain competitive. The different elements of director compensation are considered in light of the compensation packages provided to similarly-situated directors at peer companies.

The Nominating & Governance Committee has retained the services of Compensia to assist in evaluating the Company’s director compensation program against the relevant market. At the direction of the Nominating & Governance Committee, management created a survey (the “Director Compensation Survey”) which compared the Company’s director pay levels to those of the same peer group of companies used in the Executive Compensation Survey. The benchmarking process for director compensation used by the Nominating & Governance Committee based on the Director Compensation Survey is substantially similar to the process used by the Compensation Committee for evaluating executive compensation.

Director Compensation Policy

After consultation with Compensia and pursuant to the compensation review process described above, the Compensation Committee made certain changes to the non-employee director compensation program which were effective as of February 12, 2020. Specifically, the additional cash retainer for service as chair of the Compensation Committee was increased to $15,000 and the cash retainer for service as a member of the Compensation Committee was increased to $7,500.

Therefore, during 2020, each non-employee director was entitled to receive an annual retainer of $40,000, plus an additional (1) $20,000, in the case of the chairman of the Audit Committee, (2) $9,000, in the case of any other member of the Audit Committee, (3) $15,000, in the case of the chairman of the Compensation Committee, (4) $7,500, in the case of any other member of the Compensation Committee, (5) $12,000, in the case of the chairman of the Nominating & Governance Committee, (6) $6,000, in the case of any other member of the Nominating & Governance Committee and (7) $40,000, in the case of the Chairman of the Board. The Company’s directors do not receive meeting fees.

Each new non-employee director is entitled to receive an initial option grant valued at $200,000. The options vest monthly over three years. After the initial equity grant, each non-employee director whose service continues is entitled to receive an annual option grant valued at $100,000 that vests monthly over one year.

Directors who are employees of the Company are neither paid any fees or other remuneration nor awarded stock options, restricted stock awards or shares of Common Stock of the Company for services as members of the Board.

The maximum number of shares subject to stock awards that may be granted during any calendar year to any of our non-employee directors, taken together with any cash fees paid by the Company to such non-employee director during such calendar year, may not exceed $750,000 in total value (calculating the value of any such stock awards based on the grant date fair value of the stock awards for financial reporting purposes).

Item 13. Certain Relationships and Related Transactions, and Director Independence

Certain Relationships and Related Transactions

The following is a summary of transactions since January 1, 2019 in which (i) we have been a participant, (ii) the amount involved exceeded or will exceed $120,000, and (iii) any of our directors, executive officers or holders of more than 5% of our capital stock, or any member of their immediate family or person sharing their household, had or will have a direct or indirect material interest. Each such transaction is subject to review and pre-approval by the Audit Committee.

In December 2019, the Company commenced a rights offering, pursuant to which the holders of the Company’s Common Stock, Series X preferred stock and Series Y preferred stock as of November 29, 2019 purchased an aggregate of 1,000,000 shares of Common Stock for aggregate gross proceeds of $22.0 million (the “2019 Rights Offering”). The 2019 Rights Offering was fully backstopped by Biotechnology Value Fund, L.P. (“BVF”) and BVF purchased 845,463 shares of Common Stock pursuant to the exercise of subscriptions in the rights offering. One of the Company’s Directors, Matthew Perry, is the President of BVF. In April of 2020, BVF converted all of its Series Y convertible preferred shares. As of December 31, 2020, BVF owned approximately 37.2% of the Company’s total outstanding shares, and if all of the Series X convertible preferred shares were converted, BVF would own 56.6% of the Company’s total outstanding Common Stock.

In December 2020, the Company issued and sold an aggregate of 984,000 shares of its 8.625% Series A Cumulative Perpetual Preferred Stock (the "Series A Preferred Stock") in a public offering at a price to the public of $25.00 per share. Mr. Perry purchased 200,000 shares of the Series A Preferred Stock in the public offering at the public offering price of $25.00 per share for an aggregate amount of $5.0 million. The spouse of James Neal, our Chief Executive Officer and a director, purchased 8,000 shares of the Series A Preferred Stock in the public offering at the public offering price of $25.00 per share for an aggregate amount of $200,000.

One of our directors, Ms. Kosacz, who was elected to the Board in January 2019, was a partner at Cooley LLP, our outside legal counsel, until July 2020. We paid Cooley LLP an aggregate of approximately $0.4 million in fees in 2020 for legal services, which amount is substantially less than five percent of Cooley’s gross revenues for its 2020 fiscal year.

Procedures for Approval of Related Party Transactions

Our Board of Directors reviews the relationships that each director has with the Company and shall endeavor to have a majority of directors that are “independent directors” as defined by the SEC and Nasdaq rules. As part of the review process, the Company distributes and collects questionnaires that solicit information about any direct or indirect transactions with the Company from each of our directors and officers and legal counsel reviews the responses to these questionnaires and reports any related party transactions to the Audit Committee. We may enter into arrangements in the ordinary course of our business that involve the Company’s receiving or providing goods or services on a non-exclusive basis and at arm’s length negotiated rates or in accordance with regulated price schedules with corporations and other organizations in which a Company director, executive officer or nominee for director may also be a director, trustee or investor, or have some other direct or indirect relationship.

Our Code of Ethics requires all directors, officers and employees to avoid any situation that involves an actual or potential conflict of interest with the Company’s objectives and best interests. Employees are encouraged to direct any questions regarding conflicts of interest to the Company’s Chief Financial Officer or legal department. All related party transactions involving the Company’s directors or executive officers or members of their immediate families must be reviewed and approved in writing in advance by the Audit Committee.

Board Independence

As required under the Nasdaq listing standards, a majority of the members of a listed company’s board of directors must qualify as “independent,” as affirmatively determined by the board of directors. In addition, Nasdaq rules require that, subject to specified exceptions, each member of a listed company’s audit, compensation and nominating committees

72

Table of Contents

be independent within the meaning of Nasdaq rules. Audit Committee members must also satisfy the independence criteria set forth in Rule 10A-3 under the Exchange Act.

Our Board undertook a review of the independence of each director and considered whether any director has a material relationship with us that could compromise his or her ability to exercise independent judgment in carrying out his or her responsibilities. As a result of this review, our Board determined that each of Ms. Hernday, Messrs. Van Ness, Limber, Wyszomierski and Perry qualifies as an “independent” director within the meaning of the Nasdaq rules. With respect to Ms. Kosacz, who was a partner of Cooley LLP, our outside legal counsel, for a portion of 2020, our Board determined that she was independent for purposes other than serving on the Audit Committee or Compensation Committee, each of which she is not a member. Accordingly, a majority of our directors are independent, as required under Nasdaq rules. Our non-employee directors have been meeting, and we anticipate that they will continue to meet, in regularly scheduled executive sessions at which only non-employee directors are present.

All of the members of the Compensation Committee are “independent,” as required by Nasdaq Rules 5605(a)(2) and 5605(d)(2). In determining independence within the meaning of Nasdaq Rules pertaining to membership of the Compensation Committee, our Board determined, based on its consideration of factors specifically relevant to determining whether any such director has a relationship to us that is material to that director’s ability to be independent from management in connection with the duties of a compensation committee member, that no member of the Compensation Committee has a relationship that would impair that member’s ability to make independent judgments about our executive compensation.

Pre-Approval Policies and Procedures

The Audit Committee’s policy is to pre-approve all audit and permissible non-audit services provided by the Company’s independent accountants. Pre-approval generally is provided for up to one year, is detailed as to the particular service or category of services and generally is subject to a specific budget. The Audit Committee may also pre-approve particular services on a case-by-case basis. In assessing requests for services by the independent accountants, the committee considers whether such services are consistent with the auditor’s independence, whether the independent accountants are likely to provide the most effective and efficient service based on their familiarity with the Company, and whether the service could enhance the Company’s ability to manage or control risk or improve audit quality. The Audit Committee has delegated pre-approval authority to its chairman, who must report any decisions to the Audit Committee at its next scheduled meeting.

The Audit Committee pre-approved 100% of all audit and other services provided by Deloitte & Touche LLP, our current independent registered public accounting firm, in 2019 and 2020.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Stockholders and the Board of Directors of XOMA Corporation

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of XOMA Corporation and subsidiaries (the "Company") as of December 31, 2020 and 2019, the related consolidated statements of operations and comprehensive income (loss), stockholders' equity, and cash flows, for the each of the two years in the period ended December 31, 2020, and the related notes (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2020 and 2019, and the results of its operations and its cash flows for the each of the two years in the period ended December 31, 2020, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current-period audit of the financial statements that was communicated or required to be communicated to the audit committee and that (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Long-Term Royalty Receivables — Refer to Notes 2 and 5 to the financial statements

Critical Audit Matter Description

The Company has purchased rights to receive a portion of certain future developmental, regulatory and commercial sales milestones, royalties, and option fees on sales of products currently in clinical development. As of December 31, 2020, the carrying value of the long-term royalty receivables (“milestone and royalty rights”) is $34.6 million. The Company accounts for milestone and royalty rights on a non-accrual basis using the cost recovery method. The milestone and royalty rights relate to developmental pipeline products which are non-commercialized, non-approved products that require FDA or other regulatory approval, and thus have uncertain cash flows. Management assesses any impairment indicators and changes in expected recoverability of the long-term receivable asset regularly.

The determination of impairment indicators requires obtaining and assessing all available information regarding the developmental pipeline products as of the Company’s financial reporting dates. The Company obtains information through available sources including: 1) updates from the selling party of the milestone and royalty rights, 2) publicly available clinical trial data and news, and 3) public disclosures provided by the research companies developing the products.

F-1

Table of Contents

We identified the accounting evaluation of impairment indicators as a critical audit matter, primarily due to the Company’s reliance on third parties to disclose updates to the Company timely for the Company's required financial reporting deadlines. The timing of disclosure to the Company of a change in the use, or intent for future use, of the licenses related to the milestone and royalty rights could have a significant impact on the fair value of milestone and royalty rights and a significant change in fair value could cause a significant impairment. Performing audit procedures to evaluate whether management had appropriately identified impairment indicators involved challenging and complex auditor judgment, including the need to involve more experienced auditors in assessing the completeness of available information and if any available public information represents an impairment indicator as of the Company’s financial reporting date.

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to the evaluation of assumptions used in the impairment assessment of the long-term royalty receivables included, but were not limited to, the following:

Considering the impact of changes in the regulatory environment on management’s impairment indicator conclusions.

We evaluated the Company’s assessment of impairment indicators by developing an independent expectation of impairment indicators through research of third-party disclosures and clinical trial news for programs associated with the milestone and royalty rights and comparing such expectation to those included in the impairment analysis.

We inspected the Company’s documentation of inquiries and written correspondence to obtain program updates from the selling parties of the milestone and royalty rights throughout the year and through the Company’s reporting date.  

Confirmed with the selling parties of the milestone and royalty rights that complete information known to the selling party regarding the associated research programs was provided timely, completely, and accurately to the Company.

XOMA Corporation

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Description of Business

XOMA Corporation (referred to as “XOMA” or the “Company”), a Delaware corporation, is a biotech royalty aggregator with a sizable portfolio of economic rights to future potential milestone and royalty payments associated with partnered pre-commercial therapeutic candidates. The Company’s portfolio was built through licensing its proprietary products and platforms from its legacy discovery and development business, combined with acquisitions of rights to future milestones and royalties that the Company has made since the royalty aggregator business model was implemented in 2017. The Company’s drug royalty aggregator business is focused on early to mid-stage clinical assets primarily in Phase 1 and 2 with blockbuster potential licensed to large-cap partners. The Company expects that most of its future revenue will be based on payments the Company may receive for milestones and royalties related to these programs.

Liquidity and Financial Condition

The Company has incurred significant operating losses and negative cash flows from operations since its inception. As of December 31, 2020, the Company had unrestricted and restricted cash of $84.2 million and $2.1 million, respectively. As of December 31, 2020, the current and non-current portion of restricted cash was $1.6 million and $0.5 million, respectively. The restricted cash balance may only be used to pay dividends on the 8.625% Series A cumulative, perpetual preferred stock (“Series A Preferred Stock”) issued in December 2020. Based on the Company’s current cash balance and its ability to control discretionary spending, such as royalty acquisitions, the Company has evaluated and concluded its financial condition is sufficient to fund its planned operations and commitments and contractual obligations for a period of at least one year following the date that these consolidated financial statements are issued.

2. Basis of Presentation and Significant Accounting Policies

Basis of Presentation

The accompanying consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany accounts and transactions among consolidated entities were eliminated upon consolidation. The accompanying consolidated financial statements were prepared in accordance with generally accepted accounting principles (“GAAP”) in the United States for financial information and with the instructions to Form 10-K and Article 10 of Regulation S-X. 

Use of Estimates

The preparation of financial statements in conformity with GAAP in the United States requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses, and related disclosures. On an ongoing basis, management evaluates its estimates including, but not limited to, those related to revenue recognition, revenue recognized under units-of-revenue method, equity securities, legal contingencies and stock-based compensation. The Company bases its estimates on historical experience and on various other market-specific and other relevant assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources.

Actual results may differ significantly from these estimates, such as the Company’s billing under government contracts and amortization of the payments received from HealthCare Royalty Partners II, L.P. (“HCRP”). Under the Company’s contracts with the National Institute of Allergy and Infectious Diseases (“NIAID”), a part of the National Institutes of Health (“NIH”), the Company billed using NIH’s provisional rates and thus is subject to future audits at the discretion of NIAID’s contracting office. In October of 2019, NIH notified the Company that it engaged KPMG to perform an audit of the Company’s incurred cost submissions for 2013, 2014 and 2015. The audit procedures were completed and the Company adjusted its estimated liability owed to NIH to $1.4 million as of December 31, 2020. The audit remains subject to further review by NIH as part of the contract close-out process and the Company may incur further liability as a result.  In addition, under the contracts with HCRP, the amortization for the reporting period is calculated based on the

payments expected to be made by the licensees to HCRP over the term of the arrangement. Any changes to the estimated payments by the licensees to HCRP can result in a material adjustment to revenue previously reported.

The COVID-19 pandemic has resulted in a global slowdown of economic activity which has led to delays and could result in further delays or terminations of some clinical trials underlying the Company’s royalty purchase agreements. Estimates and assumptions about future events and their effects cannot be determined with certainty and therefore require the exercise of judgment. These estimates may change, as new events occur and additional information is obtained, and are recognized in the condensed consolidated financial statements as soon as they become known. Actual results could differ from those estimates and any such differences may be material to the Company’s financial statements.

Cash and Restricted Cash

Cash consists of bank deposits held in business checking and interest-bearing deposit accounts. As of December 31, 2020 and 2019, the Company did not have any cash equivalent balances, defined as highly liquid financial instruments purchased with original maturities of three months or less.

Restricted cash consists of bank deposits held to pay dividends on the Company’s 8.625% cumulative, perpetual Series A Preferred Stock.

The Company maintains cash and restricted cash balances at commercial banks. Balances commonly exceed the amount insured by the Federal Deposit Insurance Corporation. The Company has not experienced any losses in such accounts, and management believes that the Company is not exposed to any significant credit risk with respect to such cash and restricted cash.

The following table provides a reconciliation of cash and restricted cash reported within the consolidated balance sheets that sum to the total of the same amounts shown in the consolidated statements of cash flows (in thousands):

Revenue Recognition

The Company recognizes revenue from all contracts with customers according to Accounting Standards Codification (“ASC”) Topic 606, Revenue from Contracts with Customers ("ASC 606"), except for contracts that are within the scope of other standards, such as leases, insurance, collaboration arrangements and financial instruments. The Company recognizes revenue when its customer obtains control of promised goods or services, in an amount that reflects the consideration which the Company expects to receive in exchange for those goods or services.

To determine revenue recognition for arrangements that the Company determines are within the scope of ASC 606, the Company performs the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) the Company satisfies a performance obligation. The Company only applies the five-step model to contracts when it is probable that Company will collect the consideration it is entitled to in exchange for the goods or services it transfers to the customer. At contract inception, once the contract is determined to be within the scope of ASC 606, the Company assesses the goods or services promised within each contract and determines those that are performance obligations and assesses whether each promised good or service is distinct. The Company then recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation based on relative fair values, when (or as) the performance obligation is satisfied.

F-8

Table of Contents

The Company recognizes revenue from its license and collaboration arrangements and royalties. The terms of the arrangements generally include payment to the Company of one or more of the following: non-refundable, upfront license fees, development, regulatory and commercial milestone payments, and royalties on net sales of licensed products.

License of intellectual property

If the license to the Company’s intellectual property is determined to be distinct from the other performance obligations identified in the arrangement, the Company recognizes revenue from non-refundable, upfront fees allocated to the license when the license is transferred to the customer and the customer is able to use and benefit from the license. For licenses that are bundled with other promises, such as transfer of related materials, process and know-how, the Company utilizes judgement to assess the nature of the combined performance obligation to determine whether the combined performance obligation is satisfied over time or at a point in time. Under the Company’s license agreements, the nature of the combined performance obligation is the granting of licenses to the customers as the other promises are not separately identifiable in the context of the arrangement. Since the Company grants the license to a customer as it exists at the point of transfer and is not involved in any future development or commercialization of the products related to the license, the nature of the license is a right to use the Company’s intellectual property as transferred. As such, the Company recognizes revenue related to the combined performance obligation upon completion of the delivery of the related materials, process and know-how (i.e., at a point in time).

Milestone payments

At the inception of each arrangement that includes development and regulatory milestone payments, the Company evaluates whether the milestones are considered probable of being reached and estimates the amount to be included in the transaction price. ASC 606 suggests two alternatives to use when estimating the amount of variable consideration: the expected value method and the most likely amount method. Under the expected value method, an entity considers the sum of probability-weighted amounts in a range of possible consideration amounts. Under the most likely amount method, an entity considers the single most likely amount in a range of possible consideration amounts. The Company uses the most likely amount method for development and regulatory milestone payments.

If it is probable that a significant cumulative revenue reversal would not occur, the associated milestone value is included in the transaction price. Milestone payments that are not within the control of the Company or the licensee, such as regulatory approvals, are not considered probable of being achieved until those approvals are received. The transaction price is then allocated to each performance obligation on a relative stand-alone selling price basis. The Company recognizes revenue as or when the performance obligations under the contract are satisfied. At the end of each subsequent reporting period, the Company re-evaluates the probability or achievement of each such milestone and any related constraint, and if necessary, adjusts its estimates of the overall transaction price. Any such adjustments are recorded on a cumulative catch-up basis, which would affect revenue and earnings in the period of adjustment.

Royalties

For arrangements that include sales-based royalties, including milestone payments based on the level of sales, and the license is deemed to be the predominant item to which the royalties relate, the Company recognizes revenue at the later of (i) when the related sales occur, or (ii) when the performance obligation to which some or all of the royalty has been allocated has been satisfied (or partially satisfied).

Upfront payments and fees are recorded as deferred revenue upon receipt or when due and may require deferral of revenue recognition to a future period until the Company performs its obligations under these arrangements. Amounts payable to the Company are recorded as accounts receivable when the Company’s right to consideration is unconditional. The Company does not assess whether a contract has a significant financing component if the expectation at contract inception is such that the period between payment by the customer and the transfer of the promised goods or services to the customer will be one year or less.

Sale of Future Revenue Streams

The Company has sold its rights to receive certain milestones and royalties on product sales. In the circumstance where the Company has sold its rights to future milestones and royalties under a license agreement and also maintains limited continuing involvement in the arrangement (but not significant continuing involvement in the generation of the cash flows that are due to the purchaser), the Company defers recognition of the proceeds it receives for the sale of milestone or royalty streams and recognizes such unearned revenue as revenue under units-of-revenue method over the life of the underlying license agreement. Under the units-of-revenue method, amortization for a reporting period is calculated by computing a ratio of the proceeds received from the purchaser to the total payments expected to be made to the purchaser over the term of the agreement, and then applying that ratio to the period’s cash payment.

Estimating the total payments expected to be received by the purchaser over the term of such arrangements requires management to use subjective estimates and assumptions. Changes to the Company’s estimate of the payments expected to be made to the purchaser over the term of such arrangements could have a material effect on the amount of revenues recognized in any particular period.

Stock-Based Compensation

The Company recognizes compensation expense for all stock-based payment awards made to the Company’s employees, consultants and directors that are expected to vest based on estimated fair values. The valuation of stock option awards is determined at the date of grant using the Black-Scholes Option Pricing Model (the “Black-Scholes Model”). The Black-Scholes Model requires inputs such as the expected term of the option, expected volatility and risk-free interest rate. To establish an estimate of expected term, the Company considers the vesting period and contractual period of the award and its historical experience of stock option exercises, post-vesting cancellations and volatility. The estimate of expected volatility is based on the Company’s historical volatility. The risk-free rate is based on the yield available on United States Treasury zero-coupon issues corresponding to the expected term of the award. The Company records forfeitures when they occur.

The Company records compensation expense for service-based awards on a straight-line basis over the requisite service period, which is generally the vesting period of the award, or to the date on which retirement eligibility is achieved, if shorter. For awards with performance-based conditions, at the point that it becomes probable that the performance conditions will be met, the Company records a cumulative catch-up of the expense from the grant date to the current date, and then amortizes the remainder of the expense over the remaining service period. Management evaluates when the achievement of a performance-based condition is probable based on the expected satisfaction of the performance conditions as of the reporting date. The amount of stock-based compensation expense recognized during a period is based on the value of the portion of the awards that are ultimately expected to vest.

The valuation of restricted stock units (“RSUs”) is determined at the date of grant using the Company’s closing stock price.

Equity Securities

The Company received shares of common stock from Rezolute, Inc. (formerly AntriaBio, Inc.) (“Rezolute”) (Note 4). Equity investments in Rezolute are classified in the consolidated balance sheets as equity securities. The equity securities are measured at fair value, with changes in fair value recorded in the other income (expense), net line item of the consolidated statement of operations and comprehensive loss at each reporting period. The Company remeasures its equity investments at each reporting period until such time that the investment is sold or disposed of. If the Company sells an investment, any realized gains and losses on the sale of the securities will be recognized in the consolidated statement of operations and comprehensive loss in the period of sale.

In October 2020, Rezolute completed a 1:50 reverse stock split of its common shares (the “Rezolute Reverse Stock Split”) and started trading on the Nasdaq Stock Market. As a result, the Company’s number of shares of Rezolute common stock was reduced from 8,093,010 shares (pre-split shares) to 161,860 shares (post-split shares).

Purchase of Rights to Future Milestones and Royalties

The Company has purchased rights to receive a portion of certain future developmental, regulatory and commercial sales milestones, royalties, and option fees on sales of products currently in clinical development. The Company acquired such rights from various entities and recorded the amount paid for these rights as long-term royalty receivables (Note 5). In addition, the Company may be obligated to make contingent payments related to certain product development milestones, fees upon exercise of options related to future license products and sales-based milestones. The contingent payments are evaluated whether they are freestanding instruments or embedded derivatives. If freestanding instruments, the contingent payments are measured at fair value at the inception of the arrangement, subject to remeasurement to fair value each reporting period. Any changes in the estimated fair value is recorded in the consolidated statement of operations and comprehensive loss.

The Company accounts for milestone and royalty rights related to developmental pipeline products on a non-accrual basis using the cost recovery method. These developmental pipeline products are non-commercialized, non-approved products that require Food and Drug Administration (“FDA”) or other regulatory approval, and thus have uncertain cash flows. The Company is not yet able to reliably forecast future cash flows given their pre-commercial stages of development. The related receivable balance is classified as noncurrent since no payments are probable to be received in the near term. Under the cost recovery method, any milestone or royalty payment received is recorded as a direct reduction of the recorded receivable balance. When the recorded receivable balance has been fully collected, any additional amounts collected are recognized as revenue.

The Company reviews public information on clinical trials, press releases and updates from its partners regularly to identify any impairment indicators or changes in expected recoverability of the long-term receivable asset. If expected future cash flows discounted to the current period are less than the carrying value of the asset, the Company will record impairment. The impairment will be recognized by reducing the financial asset to an amount that represents the present value of the most recent estimate of future cash flows. No impairment indicators were identified, and no impairment was recorded as of December 31, 2020 and December 31, 2019.

Leases

The Company entered into a lease agreement for its corporate headquarters in Emeryville, California and under its legacy business held leases for office and laboratory facilities in Berkeley, California. In connection with a series of restructuring events in 2017 and 2018, the Company completely vacated its leased facilities in Berkeley, California and subleased the space in the vacated buildings. In December 2019, the Company terminated its legacy operating leases in Berkeley, California and was fully released from any further payment obligations. As a result of the lease terminations the Company was also released from all financial obligations under its sublease agreements. The Company continues to lease its headquarters office space in Emeryville, California.

Effective January 1, 2019, the Company adopted ASC Topic 842, Leases (“ASC 842”) using the optional transition method and applied the standard only to leases that existed at that date. The Company elected the package of practical expedients allowed under ASC Topic 842, which permitted the Company to account for its existing operating leases, as of January 1, 2019, as operating leases under the new guidance, without reassessing the Company’s prior conclusions about lease identification, lease classification and initial direct costs. As a result of the adoption of the new lease accounting guidance, on January 1, 2019, the Company recognized operating lease right-of-use assets of $7.4 million and operating lease liabilities of $9.2 million.

The Company determines the initial classification and measurement of its right-of-use assets and lease liabilities at the lease commencement date and thereafter if modified. The lease term includes any renewal options and termination options that the Company is reasonably certain to exercise. The present value of lease payments is determined by using the interest rate implicit in the lease, if that rate is readily determinable; otherwise, the Company uses its incremental borrowing rate. The incremental borrowing rate is determined by using the rate of interest that the Company would pay to borrow on a collateralized basis an amount equal to the lease payments for a similar term and in a similar economic environment. The Company built its incremental borrowing rate starting with the interest rate on its fully collateralized debt and then adjusted it for lease term length.

F-11

Table of Contents

Rent expense for operating leases is recognized on a straight-line basis, unless the right-of-use asset has been impaired, over the reasonably assured lease term based on the total lease payments and is included in operating expenses in the consolidated statements of operations and comprehensive loss.

If an operating lease were to reflect impairment, the Company will recognize the amortization of the right-of-use asset on a straight-line basis over the remaining lease term with rent expense still included in operating expenses in the consolidated statements of operations and comprehensive loss.

For all leases, rent payments that are based on a fixed index or rate at the lease commencement date are included in the measurement of lease assets and lease liabilities at the lease commencement date.

The Company has elected the practical expedient to not separate lease and non-lease components. The Company’s non-lease components are primarily related to property maintenance, which varies based on future outcomes, and thus is recognized in rent expense when incurred.

Income Taxes

The Company accounts for income taxes using the liability method under which deferred tax assets and liabilities are determined based on differences between financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. Valuation allowances are established when necessary to reduce deferred tax assets to the amount which is more likely than not to be realizable.

The recognition, derecognition and measurement of a tax position is based on management’s best judgment given the facts, circumstances and information available at each reporting date. The Company’s policy is to recognize interest and penalties related to the underpayment of income taxes as a component of income tax expense. To date, there have been no interest or penalties charged in relation to the unrecognized tax benefits.

Prior Period Reclassifications

Within the consolidated statement of cash flows, the Company separately presented proceeds from issuances of equity securities from payments of equity issuance costs for the prior period to conform with current period presentation.

Net Income (Loss) per Share Attributable to Common Stockholders

The Company calculates basic and diluted income (loss) per share attributable to common stockholders using the two-class method. The Company’s convertible Series X and Series Y preferred stocks participate in any dividends declared by the Company on its common stock and are therefore considered to be participating securities. The Company’s Series A Preferred Stock does not participate in any dividends or distribution by the Company on its common stock and is therefore not considered to be a participating security.

Under the two-class method, net income, as adjusted for any accumulated dividends on Series A Preferred Stock for the period and any deemed dividends related to beneficial conversion features on convertible preferred stock, if applicable, is allocated to each class of common stock and participating security as if all of the net income for the period had been distributed. Undistributed earnings allocated to participating securities are subtracted from net income in determining net income attributable to common stockholders. During periods of loss, the Company allocates no loss to participating securities because they have no contractual obligation to share in the losses of the Company. Basic net income (loss) per share attributable to common stockholders is then calculated by dividing the net income (loss) attributable to common stockholders by the weighted average number of shares of common stock outstanding during the period. All participating securities are excluded from the basic weighted average common shares outstanding.

Diluted net income (loss) per share attributable to common stockholders is based on the weighted average number of shares outstanding during the period, adjusted to include the assumed exercise of certain stock options and warrants for common stock. The calculation of diluted net income (loss) per share attributable to common stockholders requires that, to the extent the average market price of the underlying shares for the reporting period exceeds the exercise price of any

F-12

Table of Contents

outstanding options or warrants, the presumed exercise of such securities are dilutive to net income (loss) per share attributable to common stockholders for the period. Adjustments to the denominator are required to reflect the related dilutive shares. The Company’s Series A Preferred Stock becomes convertible upon the occurrence of specific events other than the Company’s share price and therefore, is not included in the diluted shares until the contingency is resolved.

Comprehensive Income (Loss)

Comprehensive income (loss) is comprised of two components: net income (loss) and other comprehensive income (loss). Other comprehensive income (loss) refers to gains and losses that under U.S. GAAP are recorded as an element of stockholders’ equity but are excluded from net income (loss). The Company did not record any transactions within other comprehensive income (loss) in the periods presented and, therefore, the net income (loss) and comprehensive income (loss) were the same for all periods presented.

Accounting Pronouncements Recently Adopted

In August 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2018-13, Fair Value Measurement (Topic 820) (“ASU 2018-13”), which modifies, removes and adds certain disclosure requirements on fair value measurements based on the FASB Concepts Statement, Conceptual Framework for Financial Reporting—Chapter 8: Notes to Financial Statements. The ASU is effective for the Company’s interim and annual reporting periods during the year ending December 31, 2020, and all annual and interim reporting period thereafter. The amendments on changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements and the narrative description of measurement uncertainty should be applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. All other amendments should be applied retrospectively to all periods presented upon their effective date. Early adoption is permitted upon issuance of ASU 2018-13. An entity is permitted to early adopt any removed or modified disclosures upon issuance of ASU 2018-13 and delay adoption of the additional disclosures until their effective date. The Company early adopted the guidance related to removal of disclosures upon issuance of this ASU and adopted the deferred provisions as permitted under the ASU in the first quarter of 2020. The adoption of ASU 2018-13 did not have a material impact on the Company’s consolidated financial statements.

In November 2018, the FASB issued ASU 2018-18, Collaborative Arrangements (Topic 808) “Clarifying the Interaction between Topic 808 and Topic 606,” which requires transactions in collaborative arrangements to be accounted for under ASC 606 if the counterparty is a customer for a good or service that is a distinct unit of account. The new standard also precludes an entity from presenting consideration from transactions with a collaborator that is not a customer together with revenue recognized from contracts with customers. The ASU is effective for the Company’s interim and annual reporting periods during the year ending December 31, 2020, and all annual and interim reporting period thereafter. Early adoption is permitted, but no earlier than an entity’s adoption date of Topic 606. This ASU requires retrospective adoption to the date the Company adopted ASC 606, January 1, 2018, by recognizing a cumulative-effect adjustment to the opening balance of retained earnings of the earliest annual period presented. The Company may elect to apply the ASU retrospectively either to all contracts or only to contracts that are not completed at the date it initially applied ASC 606. The Company adopted ASU 2018-18 as of January 1, 2020. The adoption of ASU 2018-18 did not have a material impact on the Company’s consolidated financial statements.

Recent Accounting Pronouncements

In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. ASU 2016-13 replaced the incurred loss impairment methodology under current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. ASU 2016-13 requires use of a forward-looking expected credit loss model for accounts receivables, loans, and other financial instruments. Adoption of the standard requires using a modified retrospective approach through a cumulative-effect adjustment to retained earnings as of the effective date to align existing credit loss methodology with the new standard. ASU 2016-13 will be effective for all entities except public companies that are not smaller reporting companies for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years, using a modified retrospective approach. Early adoption is permitted. The Company

plans to adopt ASU 2016-13 and related updates as of January 1, 2023. The Company is currently evaluating the impact of adopting this new accounting guidance on its consolidated financial statements.

In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. The amendments in ASU 2019-12 are intended to simplify various aspects related to accounting for income taxes. ASU 2019-12 removes certain exceptions to the general principles in Topic 740 and also clarifies and amends existing guidance to improve consistent application. ASU 2019-12 is effective for the Company on January 1, 2021. The Company is evaluating the impact of ASU 2019-12, but does not expect adopting this new accounting guidance will have a material impact on its consolidated financial statements.

In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. These amendments provide temporary optional guidance to ease the potential burden in accounting for reference rate reform. The ASU provides optional expedients and exceptions for applying generally accepted accounting principles to contract modifications and hedging relationships, subject to meeting certain criteria, that reference LIBOR or another reference rate expected to be discontinued. It is intended to help stakeholders during the global market-wide reference rate transition period. The guidance is effective for all entities as of March 12, 2020 through December 31, 2022 and can be adopted as of any date from the beginning of an interim period that includes or is subsequent to March 12, 2020. The Company is evaluating the impact of adopting this new accounting guidance on its consolidated financial statements.

In August 2020, the FASB issued ASU 2020-06, Debt – Debt with Conversion and Other Options (Subtopic 470-20) and Derivative and Hedging – Contracts in Entity’s Own Equity (Subtopic 815-40). This ASU reduces the number of accounting models for convertible debt instruments and convertible preferred stock and amends the guidance for the derivatives scope exception for contracts in an entity’s own equity to reduce form-over-substance-based accounting conclusion. In addition, this ASU improves and amends the related EPS guidance. These amendments are effective for the Company for fiscal years beginning after December 15, 2023, including interim period within those fiscal years. Early adoption is permitted, but no earlier than fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. Adoption is either a modified retrospective method or a fully retrospective method of transition. The Company is currently evaluating the impacts of the provisions of ASU 2020-06 and the Company does not expect this ASU to have a material impact on its consolidated financial statements.

Novartis International – Anti-TGFβ Antibody (NIS793)

On September 30, 2015, the Company and Novartis International Pharmaceutical Ltd. (“Novartis International”) entered into a license agreement (the “Anti-TGFβ Antibody License Agreement”) under which the Company granted Novartis International an exclusive, world-wide, royalty-bearing license to the Company’s anti-transforming growth factor beta (“TGFβ”) antibody program (now “NIS793”). Under the terms of the Anti-TGFβ Antibody License Agreement, Novartis International has worldwide rights to NIS793 and is responsible for the development and commercialization of antibodies and products containing antibodies arising from NIS793. Unless terminated earlier, the Anti-TGFβ Antibody License Agreement will remain in effect, on a country-by-country and product-by-product basis, until Novartis International’s royalty obligations end. The Anti-TGFβ Antibody License Agreement contains customary termination rights relating to material breach by either party. Novartis International also has a unilateral right to terminate the Anti-TGFβ Antibody License Agreement on an antibody-by-antibody and country-by-country basis or in its entirety on one hundred eighty days’ notice.

The Company concluded that there were multiple promised goods and services under the Anti-TGFβ Antibody License Agreement, including the transfer of license, regulatory services and transfer of materials, process and know-how, which were determined to represent one combined performance obligation. The Company recognized the entire upfront payment of $37.0 million as revenue in the consolidated statement of comprehensive loss in 2015 as it had completed its performance obligations as of December 31, 2015.

During the year ended December 31, 2017, Novartis International achieved a clinical development milestone pursuant to the Anti-TGFβ Antibody License Agreement, and as a result, the Company earned a $10.0 million milestone payment which was recognized as license fees in the consolidated statement of operations and comprehensive income (loss). The Company is eligible to receive up to a total of $470.0 million in development, regulatory and commercial milestones under the Anti-TGFβ Antibody License Agreement.

The Company concluded that the development and regulatory milestone payments are solely dependent on Novartis International’s performance and achievement of the specified events. The Company determined that it is not probable that a significant cumulative revenue reversal will not occur in future periods for these future payments. Therefore, the remaining development and regulatory milestones are fully constrained and excluded from the transaction price until the respective milestone is achieved. Any consideration related to commercial milestones (including royalties) will be recognized when the related sales occur as they were determined to relate predominantly to the licenses granted to Novartis International and therefore, have also been excluded from the transaction price. At the end of each reporting period, the Company will update its assessment of whether an estimate of variable consideration is constrained and update the estimated transaction price accordingly.

The Company is also eligible to receive royalties on sales of licensed products, which are tiered based on sales levels and range from a mid single-digit percentage rate to up to a low double-digit percentage rate. Novartis International’s

F-15

Table of Contents

obligation to pay royalties with respect to a particular product and country will continue for the longer of the date of expiration of the last valid patent claim covering the product in that country, or ten years from the date of the first commercial sale of the product in that country.

On October 21, 2020, the first patient was dosed in Novartis International's NIS793 Phase 2 clinical trial and the Company earned a $25.0 million milestone payment. As specified under the terms the Anti-TGFβ Antibody License Agreement, the Company received $17.7 million in cash and the remaining balance of $7.3 million was recognized as a reduction to the Company's debt obligation to Novartis.

As of December 31, 2020 and December 31, 2019, there are no contract assets or contract liabilities related to this arrangement. None of the costs to obtain or fulfill the contract were capitalized. No revenue was recognized for the year ended December 31, 2019. The Company recognized $25.0 million as revenue from contracts with customers in the consolidated statement of operations and comprehensive income (loss) for the year ended December 31, 2020.

Novartis – Gevokizumab (VPM087) and IL-1 Beta

On August 24, 2017, the Company and Novartis Pharma AG (“Novartis”) entered into a license agreement (the “Gevokizumab License Agreement”) under which the Company granted to Novartis an exclusive, worldwide, royalty-bearing license to gevokizumab (“VPM087”), a novel anti-Interleukin-1 (“IL-1”) beta allosteric monoclonal antibody and related know-how and patents (altogether, the “XOMA IP”). Under the terms of the Gevokizumab License Agreement, Novartis is solely responsible for the development and commercialization of VPM087 and products containing VPM087.

On August 24, 2017, pursuant to a separate agreement (the “IL-1 Target License Agreement”), the Company granted to Novartis non-exclusive licenses to its intellectual property covering the use of IL-1 beta targeting antibodies in the treatment and prevention of cardiovascular disease and other diseases and conditions, and an option to obtain an exclusive license (the “Exclusivity Option”) to such intellectual property for the treatment and prevention of cardiovascular disease.

Under the Gevokizumab License Agreement, the Company received total consideration of $30.0 million for the license and rights granted to Novartis. Of the total consideration, $15.7 million was paid in cash and $14.3 million (equal to €12.0 million) was paid by Novartis Institutes for BioMedical Research, Inc. (“NIBR”), on behalf of the Company, to settle the Company’s outstanding debt with Les Laboratories Servier (“Servier”) (the “Servier Loan”). In addition, NIBR extended the maturity date on the Company’s debt to Novartis. The Company also received $5.0 million cash related to the sale of 539,131 shares of the Company’s common stock, at a purchase price of $9.2742 per share. The fair market value of the common stock issued to Novartis was $4.8 million, based on the closing stock price of $8.93 per share on August 24, 2017, resulting in a $0.2 million premium paid to the Company.

Based on the achievement of pre-specified criteria, the Company is eligible to receive up to $438.0 million in development, regulatory and commercial milestones under the Gevokizumab License Agreement. The Company is also eligible to receive royalties on sales of licensed products, which are tiered based on sales levels and range from the high single-digits to mid-teens. Under the IL-1 Target License Agreement, the Company received an upfront cash payment of $10.0 million and is eligible to receive low single-digit royalties on canakinumab sales in cardiovascular indications covered by the Company’s patents. Should Novartis exercise the Exclusivity Option, the royalties on canakinumab sales will increase to the mid single-digits.

Unless terminated earlier, the Gevokizumab License Agreement and IL-1 Target License Agreement will remain in effect, on a country-by-country and product-by-product basis, until Novartis’ royalty obligations end. The two agreements contain customary termination rights relating to material breach by either party. Novartis also has a unilateral right to terminate the Gevokizumab License Agreement on a product-by-product and country-by-country basis or in its entirety on six months’ prior written notice to the Company. Under the IL-1 Target License Agreement, Novartis has a unilateral right to terminate the agreement on a product-by-product and country-by-country basis or in its entirety upon a prior written notice.

Table of Contents

The Gevokizumab License Agreement and IL-1 Target License Agreement were accounted for as one arrangement because they were entered into at the same time in contemplation of each other. The Company concluded that there are multiple promised goods and services under the combined arrangement, including the transfer of license to IL-1 beta targeting antibodies, and the transfer of license, know-how, process, materials and inventory related to the VPM087 antibody, which were determined to represent two distinct performance obligations. The Company determined that the Exclusivity Option is not an option with material right because the upfront payments to the Company were not negotiated to provide an incremental discount for the future additional royalties upon exercise of the Exclusivity Option. Therefore, the Company concluded that the Exclusivity Option is not a performance obligation. The additional royalties will be recognized as revenue when, and if, Novartis exercises its option because the Company has no further performance obligations at that point.

At the inception of the arrangement, the Company determined that the transaction price under the arrangement was $40.2 million, which consisted of the $25.7 million upfront cash payments, the $14.3 million Servier Loan payoff and the $0.2 million premium on the sale of the common stock. The transaction price was allocated to the two performance obligations based on their standalone selling prices. The Company determined that the nature of the two performance obligations is the right to use the licenses as they exist at the point of transfer, which occurred when the transfer of materials, process and know-how, and filings to regulatory authority were completed. During the year ended December 31, 2017, the Company recognized the entire transaction price of $40.2 million as revenue upon completion of the delivery of the licenses and related materials, process and know-how and filings to regulatory authority.

The Company concluded that the development and regulatory milestone payments are solely dependent on Novartis’ performance and achievement of specified events. The Company determined that it is not probable that a significant cumulative revenue reversal will not occur in future periods for these future payments. Therefore, the development and regulatory milestones are fully constrained and excluded from the transaction price as of December 31, 2020. Any consideration related to commercial milestones (including royalties) will be recognized when the related sales occur as they were determined to relate predominantly to the licenses granted to Novartis and therefore, have also been excluded from the transaction price. At the end of each reporting period, the Company will update its assessment of whether an estimate of variable consideration is constrained and update the estimated transaction price accordingly.

As of December 31, 2020 and December 31, 2019, there are no contract assets or contract liabilities related to this arrangement and none of the costs to obtain or fulfill the contract were capitalized. The Company did not recognize any revenue related to this arrangement during the years ended December 31, 2020 and 2019.

Takeda

On November 1, 2006, the Company entered into a collaboration agreement with Takeda Pharmaceutical Company Limited (“Takeda”) (the “Takeda Collaboration Agreement”) under which the Company agreed to discover and optimize therapeutic antibodies against multiple targets selected by Takeda.

Under the terms of the Takeda Collaboration Agreement, the Company may receive additional milestone payments aggregating up to $19.0 million relating to TAK-079 (mezagitamab) and low single-digit royalties on future sales of all products subject to this license. The Company’s right to milestone payments expires on the later of the receipt of payment from Takeda of the last amount to be paid under the agreement or the cessation by Takeda of all research and development activities with respect to all program antibodies, collaboration targets or collaboration products. The Company’s right to royalties expires on the later of 13.5 years from the first commercial sale of each royalty-bearing discovery product or the expiration of the last-to-expire licensed patent (or 12 years from first commercial sale if there is significant generic competition post patent-expiration).

F-17

Table of Contents

In February 2009, the Company expanded the existing collaboration to provide Takeda with access to multiple antibody technologies, including a suite of research and development technologies and integrated information and data management systems. The Company may receive milestones of up to $3.3 million per discovery product candidate and low single-digit royalties on future sales of all antibody products subject to this license. The Company’s right to milestone payments expires on the later of the receipt of payment from Takeda of the last amount to be paid under the agreement or the cessation by Takeda of all research and development activities with respect to all program antibodies, collaboration targets or collaboration products. The Company’s right to royalties expires on the later of 10 years from the first commercial sale of such royalty-bearing discovery product or the expiration of the last-to-expire licensed patent.

The Company earned a milestone payment of $0.5 million during the year ended December 31, 2019. During the years ended December 31, 2020 and 2019, the Company recognized annual license fee revenue of $0.1 million from Takeda. On November 16, 2020, the first patient was dosed in Takeda’s Phase 2 study of mezagitamab and the Company earned a $2.0 million milestone payment from Takeda. The Company recognized $2.1 million as revenue from contracts with customers in the consolidated statement of operations and comprehensive income (loss) for the year ended December 31, 2020.

Rezolute

On December 6, 2017, the Company entered into a license agreement with Rezolute pursuant to which the Company granted an exclusive global license to Rezolute to develop and commercialize X358 (now “RZ358”) products for all indications. The Company and Rezolute also entered into a common stock purchase agreement pursuant to which Rezolute agreed to issue to the Company, as consideration for receiving the license for RZ358, a certain number of its common stock related to its future financing activities.

Under the terms of the license agreement, Rezolute is responsible for all development, regulatory, manufacturing and commercialization activities associated with RZ358 and is required to make certain development, regulatory and commercial milestone payments to the Company of up to $232.0 million in the aggregate based on the achievement of pre-specified criteria. Under the license agreement, the Company is also eligible to receive royalties ranging from the high single-digits to the mid-teens based upon annual net sales of any commercial product incorporating RZ358. Rezolute is obligated to take customary steps to advance RZ358, including using diligent efforts to commence the next clinical study for RZ358 by a certain deadline and to meet certain spending requirements on an annual basis for the program until a marketing approval application for RZ358 is accepted by the FDA. Rezolute’s obligation to pay royalties with respect to a particular RZ358 product and country will continue for the longer of the date of expiration of the last valid patent claim covering the product in that country, or twelve years from the date of the first commercial sale of the product in that country. Rezolute’s future royalty obligations in the United States will be reduced by 20% if the manufacture, use or sale of a licensed product is not covered by a valid XOMA patent claim, until such a claim is issued.

Under the terms of the license agreement, the Company is eligible to receive a low single-digit royalty on sales of Rezolute’s other non-RZ358 products from its current programs. Rezolute’s obligation to pay royalties with respect to a particular Rezolute product and country will continue for the longer of twelve years from the date of the first commercial sale of the product in that country or for so long as Rezolute or its licensee is selling such product in such country (the “Royalty Term”), provided that any such licensee royalty will terminate upon the termination of the licensee’s obligation to make payments to Rezolute based on sales of such product in such country

Rezolute had an option through June 1, 2019 to obtain an exclusive license for their choice of one of the Company’s preclinical monoclonal antibody fragments, including X129 (the “Additional Product Option”), in exchange for a $1.0 million upfront option fee and additional clinical, regulatory and commercial milestone payments to the Company of up to $237.0 million in the aggregate based on the achievement of pre-specified criteria as well as royalties ranging from the high single-digits to the mid-teens based on annual net sales. On June 1, 2019, Rezolute’s right to the Additional Product Option expired unexercised.

The license agreement contains customary termination rights relating to material breach by either party. Rezolute also has a unilateral right to terminate the license agreement in its entirety on ninety days’ notice at any time. The Company has the right to terminate the license agreement if Rezolute challenges the licensed patents.

Table of Contents

Under the license agreement and common stock purchase agreement, no consideration was exchanged upon execution of the arrangement. In consideration for receiving the license for RZ358, Rezolute agreed to issue shares of its common stock and pay cash to the Company upon the occurrence of Rezolute’s financing activities and the amounts to be paid to be based on the timing of those activities.

Rezolute License Agreement - First Amendment

In March 2018, the Company and Rezolute amended the license agreement and common stock purchase agreement. Pursuant to the as-amended terms of the license agreement and common stock purchase agreement, the Company was eligible to receive $6.0 million in cash, $8.5 million of Rezolute’s common stock, and 7,000,000 shares (140,000 post-split shares) of Rezolute’s common stock, contingent on the completion of Rezolute’s financing activities. Further, in the event that Rezolute did not complete a financing that raised at least $20.0 million in aggregate gross proceeds (“Qualified Financing”) by March 31, 2019 (the “2019 Closing”), the Company would have received an additional number of shares of Rezolute’s common stock equal to $8.5 million divided by the weighted average of the closing bid and ask prices or the average closing prices of Rezolute’s common stock on the ten-day trading period prior to March 31, 2019. Finally, in the event that Rezolute was unable to complete a Qualified Financing by March 31, 2020, the Company would have been eligible to receive $15.0 million in cash in order for Rezolute to maintain the license. Under the common stock purchase agreement, Rezolute granted the Company the right and option to sell the greater of (i) 5,000,000 shares (100,000 post-split shares) of common stock or (ii) one third of the aggregate shares held by the Company upon failure by Rezolute to list its shares of its common stock on the Nasdaq Stock Market or a similar national exchange on or prior to December 31, 2018.

During the three months ended March 31, 2018, the Company completed the delivery of the license and related materials, product data/filing, process and know-how to Rezolute. However, the Company determined that it was not probable that the Company would collect substantially all of the consideration to which it was entitled in exchange for the goods and services transferred to Rezolute. Therefore, the Company determined no contract existed as of March 31, 2018 and no revenue was recognized during the three months ended March 31, 2018 under the arrangement.  

Rezolute completed the Interim Financing Closing and the Initial Closing financing activities, as defined in the common stock purchase agreement, during the first and second quarter of 2018, respectively. As a result, XOMA received 8,093,010 shares (161,860 post-split shares) of Rezolute’s common stock and cash of $0.5 million in April 2018. Under the license agreement, XOMA was also entitled to receive $0.3 million of reimbursable technology transfer expenses from Rezolute. The Company concluded that the payment associated with the Initial Closing represented substantially all consideration for the delivered license and technology to Rezolute. Therefore, the Company determined that a contract existed between Rezolute and XOMA under ASC 606 on April 3, 2018.

The license agreement and common stock purchase agreement were accounted for as one arrangement because they were entered into at the same time in contemplation of each other. The Company concluded that there were multiple promised goods and services under the combined arrangement, including the license to RZ358, the transfer of RZ358 materials and product data/filing, and the transfer of process and know-how related to RZ358, which were determined to represent one combined performance obligation. The Company determined that the Additional Product Option was not an option with material right because there was no upfront consideration to the Company that would result to an incremental discount for the future opt in payments. Therefore, the Company concluded that the Additional Product Option was not a performance obligation. On June 1, 2019, Rezolute’s right to the Additional Product Option expired unexercised.

Table of Contents

On April 3, 2018, the Company determined that the transaction price under the arrangement was $1.8 million, which consisted of the 8,093,010 shares (161,860 post-split shares) of Rezolute’s common stock valued at $1.0 million, $0.5 million in cash, and reimbursable technology transfer expenses of $0.3 million. During the year ended December 31, 2018, the Company recognized the entire transaction price of $1.8 million as revenue upon completion of the delivery of the licenses and related materials, product data/filing, process and know-how. The change in fair value of Rezolute’s common stock after the contract inception date was due to the form of the consideration and therefore, not included in the transaction price pursuant to the accounting guidance. The Company accounts for the change in the fair value of its investment in Rezolute’s common stock in the other income (expense), net line item of the consolidated statement of operations and comprehensive loss.

The Company concluded that the development and regulatory milestone payments are solely dependent on Rezolute’s performance and achievement of the specified events. The Company determined that it is not probable that a significant cumulative revenue reversal will not occur in future periods for these future payments. Therefore, the development and regulatory milestones are fully constrained and excluded from the transaction price as of the inception of the arrangement. Any consideration related to commercial milestones (including royalties) will be recognized when the related sales occur as they were determined to relate predominantly to the licenses granted to Rezolute and therefore, have also been excluded from the transaction price. At the end of each reporting period, the Company will update its assessment of whether the estimate of variable consideration is constrained and update the estimated transaction price accordingly.

Rezolute License Agreement - Second Amendment

On January 7, 2019, the Company and Rezolute further amended the license agreement and common stock purchase agreement. The parties agreed to replace the issuance of common stock valued at $8.5 million to XOMA upon closing of a Qualified Financing with a requirement that Rezolute make five future cash payments to XOMA totaling $8.5 million through September 2020 (the “Future Cash Payments”). The amendment also provided for early payment of the Future Cash Payments (only until the $8.5 million was reached) by making cash payments to XOMA equal to 15% of the net proceeds of each future financing following the closing of the Qualified Financing, with such payments to be credited against any remaining unpaid Future Cash Payments in reverse order of their future payment date. In addition, the license agreement amendment revised the amount Rezolute is required to expend on development of RZ358 and related licensed products, revised provisions with respect to Rezolute’s diligence efforts in conducting clinical studies and eliminated XOMA’s right to appoint a member to Rezolute’s board of directors.

The common stock purchase agreement was amended to remove certain provisions related to the issuance of equity to XOMA in accordance with the new provisions regarding the Future Cash Payments in the license agreement. Lastly, the common stock purchase agreement was amended to provide the Company the right and option to sell up to 5,000,000 shares (100,000 post-split shares) of Rezolute’s common stock currently held by XOMA back to Rezolute upon failure by Rezolute to list its shares of its common stock on the Nasdaq Stock Market or a similar national exchange on or prior to December 31, 2019. As of December 31, 2019, Rezolute failed to list its shares of common stock on the Nasdaq Stock Market or a similar exchange. Up to 2,500,000 shares (50,000 post-split shares) may be sold back to Rezolute during calendar year 2020. During the quarter ended December 31, 2020 Rezolute began trading on the Nasdaq Stock Market and the Company has not sold any of its shares.

On January 30, 2019, Rezolute closed a preferred stock financing for gross proceeds of $25.0 million, which triggered the Qualified Financing event defined under the amended common stock purchase agreement resulting in cash consideration due to XOMA of $5.5 million. In addition, the Company received from Rezolute a reimbursable technology transfer expense of $0.3 million. The cash consideration and technology reimbursement were received in February 2019.

As of March 31, 2019, Rezolute completed all financing activities, as defined in the license agreement and common stock purchase agreement, and the Company was eligible to receive $8.5 million in Future Cash Payments through September 2020 (in addition to any clinical, regulatory and annual net sales milestone payments and royalties). The Company concluded that the Future Cash Payments are dependent on Rezolute’s ability to raise additional capital through future financing activities. The Company applied the variable consideration constraint to the Future Cash Payments and determined that it was probable that a significant revenue reversal would not occur in future periods for only $2.5 million of the total amount as of March 31, 2019 and recognized $2.5 million revenue in that quarter.   

In July and August 2019, Rezolute received additional cash through two common stock financing events, which triggered early payment of $3.4 million of the unrecognized $6.0 million of total Future Cash Payments. In addition, the

F-20

Table of Contents

Company received the $1.5 million payment due September 30, 2019, resulting in a total of $4.9 million cash received from Rezolute in the third quarter of 2019. The Company re-assessed the outstanding $3.6 million of Future Cash Payments and determined that a significant revenue reversal was not probable due to Rezolute’s recent common stock financing events. Therefore, in the third quarter of 2019, the Company recognized $6.0 million as revenue related to the remaining Future Cash Payments. In the fourth quarter of 2019, the Company received the scheduled $1.0 million Future Cash Payment from Rezolute.

Rezolute License Agreement - Third Amendment

On March 31, 2020, the Company and Rezolute further amended the license agreement to extend the payment schedule for the remaining $2.6 million in Future Cash Payments. The amendment to the payment terms was in response to Rezolute’s need to preserve cash as a result of the COVID-19 pandemic and was agreed to by the Company. The extended payment schedule did not impact the total amount due, but instead, spread the $2.6 million into seven quarterly payments to be paid through September 30, 2021. The amended license agreement requires that in the event Rezolute completes a Qualified Financing at any time between March 31, 2020 and the date of the final payment, Rezolute shall pay all amounts outstanding within fifteen days following the closing of the Qualified Financing.

In the first quarter of 2020, the Company received the scheduled $0.4 million Future Cash Payment from Rezolute. The Company evaluated Rezolute’s cash position as of March 31, 2020, including the estimated impact of the COVID-19 pandemic, and determined payments scheduled beyond September 30, 2020 were unlikely to be collected unless Rezolute was able to obtain additional funding, which had not occurred as of March 31, 2020. Therefore, for the three months ended March 31, 2020, the Company recorded $1.4 million in bad debt expense related to the Future Cash Payments. The Company received the scheduled $0.4 million and $0.4 million Future Cash Payments from Rezolute in the second and third quarters of 2020, respectively. The Company reassessed the collectability of the outstanding receivables and determined that the bad debt allowance of $1.4 million remained appropriate as of September 30, 2020, as the Company assessed that the financing was not probable as of the balance sheet date and as such the Company continued to have an incurred loss with respect to the collection of the remaining receivable.

On October 9, 2020, Rezolute completed a private placement of its equity securities with gross proceeds of $41.0 million, which was considered a Qualified Financing event under the Third Amendment. The Qualified Financing resulted in acceleration of the remaining receivables of $1.4 million due from Rezolute, and the Company received the entire amount in October 2020. The Company recognized $1.4 million as a reversal of bad debt expense in the fourth quarter of 2020.

During the quarter ended December 31, 2020, Rezolute completed a 1:50 reverse stock split of its common shares and started trading on the Nasdaq Stock Market. As a result, the Company’s number of shares of Rezolute common stock was reduced from 8,093,010 shares (pre-split shares) to 161,860 shares (post-split shares).

As of December 31, 2020 and December 31, 2019, there were no contract assets or contract liabilities related to this arrangement. None of the costs to obtain or fulfill the contract were capitalized. No revenue was recognized for the year ended December 31, 2020. During the year ended December 31, 2019, the Company recognized $14.0 million as revenue from Rezolute, which consisted of the $5.5 million consideration paid upon the Qualified Financing event and $8.5 million Future Cash Payments.

The Company reassessed the development and regulatory milestones and concluded that such variable consideration is fully constrained and excluded from the transaction price as of December 31, 2020 and 2019.

Janssen Biotech

The Company and Janssen Biotech, Inc. (“Janssen”) were parties to a license agreement which was terminated in 2017. In August 2019, the Company and Janssen entered into a new agreement pursuant to which the Company granted a non-exclusive license to Janssen to develop and commercialize certain drug candidates under the XOMA patents and know-how. Under the new agreement, Janssen made a one-time payment of $2.5 million to XOMA. Additionally, for each drug candidate, the Company is entitled to receive milestone payments of up to $3.0 million upon Janssen’s achievement of certain clinical development and regulatory approval events. Additional milestones may be due for drug candidates which are the subject of multiple clinical trials. Upon commercialization, the Company is eligible to receive 0.75% royalty on net sales of each product. Janssen’s obligation to pay royalties with respect to a particular product and country will continue until the eighth-year and sixth-month anniversary of the first commercial sale of the product in such country. The new agreement will remain in effect unless terminated by mutual written agreement of the parties.

The Company concluded that the new agreement should be accounted for separately from any prior arrangements with Janssen and that the license grant is the only performance obligation under the new agreement. The Company recognized the entire one-time payment of $2.5 million as revenue in the consolidated statement of comprehensive income for the year ended December 31, 2019 as it had completed its performance obligation.

The Company concluded that the development and regulatory milestone payments are solely dependent on Janssen’s performance and achievement of specified events and thus it is not probable that a significant cumulative revenue reversal will not occur in future periods for these future payments. Therefore, the development and regulatory milestones are fully constrained and excluded from the transaction price until the respective milestone is achieved. Any consideration related to royalties will be recognized when the related sales occur as they were determined to relate predominantly to the license granted to Janssen and therefore, have also been excluded from the transaction price. At the end of each reporting period, the Company will update its assessment of whether an estimate of variable consideration is constrained and update the estimated transaction price accordingly.

As of December 31, 2020 and December 31, 2019, there were no contract assets or contract liabilities related to this arrangement. None of the costs to obtain or fulfill the contract were capitalized. Milestone revenue of $0.4 million was recognized for the year ended December 31, 2020.

Zydus

On March 3, 2020, the Company and Cadila Healthcare Limited (“Zydus”) entered into a license agreement (the “Zydus Agreement”) under which the Company granted Zydus an exclusive royalty-bearing license to the Company’s anti-interleukin-2 (“IL-2”) monoclonal antibodies, including mAb19, for Zydus to develop and commercialize drug candidates in India, Brazil, Mexico and certain other emerging markets. The Company retains rights in all other territories, subject to a Zydus right of first negotiation. Under the terms of the Zydus Agreement, Zydus is responsible for the development and commercialization of IL-2 based immuno-oncology drug candidates. XOMA is entitled to receive up to $0.5 million development and regulatory milestone payments, up to $23.5 million commercial milestone payments, and mid single-digit to low teens royalties from Zydus. The Company is also eligible to share out-licensing revenue received by Zydus should Zydus (sub)license to third parties, which share is tiered based on clinical trial stage and range from a low to mid double-digit percentage rate. Unless terminated earlier, the Zydus Agreement will remain in effect, on a product-by-product basis, until all payment obligations end. The Zydus Agreement contains customary termination rights relating to material breach by either party. Zydus also has a unilateral right to terminate the agreement upon required written notice in advance if certain conditions are met.

The Company concluded that there is one performance obligation, and it had completed its performance obligation in the first quarter of 2020. The development and regulatory milestone payments are solely dependent on Zydus’ performance and achievement of the specified events. The Company determined that it is not probable that a significant cumulative revenue reversal will not occur in future periods for these future payments. Therefore, the development and regulatory milestones are fully constrained and excluded from the transaction price as of December 31, 2020. Any consideration related to commercial milestones (including royalties) will be recognized when the related sales occur as they were determined to relate predominantly to the license granted to Zydus and therefore, have also been excluded from the transaction price. Out-licensing revenue sharing will be recognized if and when Zydus receives or earns its out-

licensing revenue. At the end of each reporting period, the Company will update its assessment of whether an estimate of variable consideration is constrained and update the estimated transaction price accordingly.

As of December 31, 2020, there were no contract assets or contract liabilities related to this arrangement. None of the costs to obtain or fulfill the contract were capitalized. No revenue was recognized for the year ended December 31, 2020.

NIAID

Prior to the sale of the Company’s biodefense business, the Company performed services under a $64.8 million multiple-year contract funded with federal funds from NIAID (Contract No. HHSN272200800028C), for development of anti-botulinum antibody product candidates. The contract work was being performed on a cost plus fixed fee basis over a three-year period. The Company recognized revenue under the arrangement as the services were performed on a proportional performance basis. Consistent with the Company’s other contracts with the U.S. government, invoices were provisional until finalized. The Company operated under provisional rates from 2010 through 2014, subject to adjustment based on actual rates upon agreement with the government. In 2014, upon completion of NIAID’s review of hours and external expenses, XOMA agreed to exclude certain hours and external expenses resulting in a $0.4 million receivable and $0.8 million deferred revenue balances. As of December 31, 2017, the Company wrote off the $0.4 million receivable from NIAID as the likelihood of collection was remote. In October of 2019, NIH, which includes NIAID, notified the Company that it engaged KPMG to perform an audit of the Company’s incurred cost submissions for 2013, 2014 and 2015. The KPMG testing procedures were completed in December 2020. As a result, the Company recognized $1.4 million as estimated refund liabilities owed to NIH on the consolidated balance sheet as of December 31, 2020. The additional $0.6 million liability was recognized as a reduction of revenue from contracts with customers in the consolidated statement of operations and comprehensive income (loss) for the year ended December 31, 2020. The audit remains subject to further review by NIH as part of the contract close-out process. The Company may incur a further reduction in revenue and increase to the liability as a result of subsequent information provided by NIH.    

Sale of Future Revenue Streams

On December 21, 2016, the Company entered into two royalty interest sale agreements (together, the “Royalty Sale Agreements”) with HCRP. Under the first Royalty Sale Agreement, the Company sold its right to receive milestone payments and royalties on future sales of products subject to a License Agreement, dated August 18, 2005, between XOMA and Wyeth Pharmaceuticals (subsequently acquired by Pfizer, Inc. (“Pfizer”)) for an upfront cash payment of $6.5 million, plus potential additional payments totaling $4.0 million in the event three specified net sales milestones were met in 2017, 2018 and 2019. Based on actual sales, 2017, 2018, and 2019 sales milestones were not achieved. Under the second Royalty Sale Agreement entered into in December 2016, the Company sold its right to receive certain royalties under an Amended and Restated License Agreement dated October 27, 2006 between XOMA and Dyax Corp. for a cash payment of $11.5 million.

The Company classified the proceeds received from HCRP as unearned revenue, to be recognized as revenue under units-of-revenue method over the life of the license agreements because of the Company’s limited continuing involvement in the Acquisition Agreements. Such limited continuing involvement is related to the Company’s undertaking to cooperate with HCRP in the event of litigation or a dispute related to the license agreements. Because the transaction was structured as a non-cancellable sale, the Company does not have significant continuing involvement in the generation of the cash flows due to HCRP and there are no guaranteed rates of return to HCRP, the Company recorded the total proceeds of $18.0 million as unearned revenue recognized under units-of-revenue method. The Company allocated the total proceeds between the two Royalty Sale Agreements based on the relative fair value of expected payments to be made to HCRP under the license agreements. The unearned revenue is being recognized as revenue over the life of the underlying license agreements under the "units-of-revenue" method. Under this method, amortization for a reporting period is calculated by computing a ratio of the allocated proceeds received from HCRP to the payments expected to be made by the licensees to HCRP over the term of the Acquisition Agreements, and then applying that ratio to the period’s cash payment. During the third quarter of 2018, the Shire product underlying the Dyax Corp. license agreement was approved, and the Company began recognizing revenue under the units-of-revenue method due to sales of the approved product.

The Company recognized $1.4 million and $1.1 million as revenue under units-of-revenue method under these arrangements during the years ended December 31, 2020 and December 31, 2019, respectively. As of December 31, 2019, the Company classified $1.1 million and $15.3 million as current and non-current unearned revenue recognized under units-of-revenue method, respectively. As of December 31, 2020, the current and non-current portion of the remaining unearned revenue recognized under units-of-revenue method was $1.5 million and $13.5 million, respectively.

On September 20, 2018, the Company entered into a royalty purchase agreement (the “Agenus Royalty Purchase Agreement”) with Agenus, Inc., and certain affiliates (collectively, “Agenus”). Under the Agenus Royalty Purchase Agreement, the Company purchased from Agenus the right to receive 33% of the future royalties on six Incyte Europe S.a.r.l. (“Incyte”) immuno-oncology assets, currently in development, due to Agenus from Incyte (net of certain royalties payable by Agenus to a third party) and 10% of all future developmental, regulatory and commercial milestones related to these assets. However, the Company did not have a right to the expected near-term milestone associated with the entry of INCAGN2390 (anti-TIM-3) into its Phase 1 clinical trial. The future royalties due to Agenus from Incyte are based on low single to mid-teen digit percentage of applicable net sales.

In addition, the Company purchased from Agenus the right to receive 33% of the future royalties on MK-4830, an immuno-oncology product currently in clinical development, due to Agenus from Merck Sharp & Dohme Corp. (“Merck”) and 10% of all future developmental, regulatory and commercial milestones related to this asset. The future royalties due to Agenus from Merck are based on low single-digit percentage of applicable net sales. Pursuant to the Agenus Royalty Purchase Agreement, the Company’s share in future potential development, regulatory and commercial milestones is up to $59.5 million. There is no limit on the amount of future royalties on sales that the Company may receive under the agreements.

Under the terms of the Agenus Royalty Purchase Agreement, the Company paid Agenus $15.0 million. The Company financed $7.5 million of the purchase price with a term loan under its Loan and Security Agreement with Silicon Valley Bank (“SVB”) (Note 8).

At the inception of the agreement, the Company recorded $15.0 million as long-term royalty receivables in the consolidated balance sheets.

In November 2020, MK-4830 advanced into Phase 2 development and Agenus earned a $10.0 million clinical development milestone under its license agreement with Merck, of which the Company earned $1.0 million. In accordance with the cost recovery method, the $1.0 million milestone received was recorded as a direct reduction of the recorded long-term royalty receivable balance.

The Company continues to assess that no further payments are probable to be received under this agreement in the near term. Under the cost recovery method, the Company does not expect to recognize any income related to milestones and royalties received until the investment has been fully collected. The Company performed its quarterly impairment assessment and no impairment indicators were identified. Accordingly, no impairment was recorded as of December 31, 2020.

Royalty Purchase Agreement with Bioasis Technologies, Inc.

On February 25, 2019, the Company entered into a royalty purchase agreement (the “Bioasis Royalty Purchase Agreement”) with Bioasis Technologies, Inc. and certain affiliates (collectively “Bioasis”). Under the Bioasis Royalty Purchase Agreement, the Company purchased potential future milestone and royalty rights from Bioasis for product candidates that are being developed pursuant to a license agreement between Bioasis and Prothena Biosciences Limited. In addition, the Company was granted options to purchase a 1% royalty right on the next two license agreements entered into between Bioasis and third-party licensees subject to certain payments and conditions as well as a right of first negotiation on subsequent Bioasis license agreements with third parties. Upon exercise of the option related to the second license agreement executed by Bioasis, the Company may be obligated to pay up to $0.3 million per licensed product. Upon exercise of the option related to the third license agreement executed by Bioasis, the Company may be obligated to pay up to $0.4 million per licensed product.

Under the terms of the Bioasis Royalty Purchase Agreement, the Company paid $0.3 million and will make contingent future cash payments of up to $0.2 million to Bioasis as the licensed product candidates reach certain development milestones (the “Bioasis Contingent Consideration”).

At the inception of the agreement, the Company recorded $0.4 million as long-term royalty receivables in its consolidated balance sheet, including the estimated fair value of the Bioasis Contingent Consideration of $0.1 million. Future changes in the estimated fair value of the contingent consideration will be recognized in the other income (expense), net line item of the consolidated statement of operations and comprehensive loss. As of December 31, 2020, there was no change in the fair value of the contingent consideration from its initial value and no amounts were paid during the year ended December 31, 2020. The Company continues to assess that no payments are probable to be received under this agreement in the near term. Under the cost recovery method, the Company does not expect to recognize any income related to milestones and royalties received until the investment has been fully collected. The Company performed its quarterly impairment assessment and no impairment indicators were identified. Accordingly, no impairment was recorded as of December 31, 2020. No impairment was recorded as of December 31, 2019.

On November 2, 2020, the Company entered into another royalty purchase agreement (the “Second Bioasis Royalty Purchase Agreement”) with Bioasis.

(“Chiesi”). The Company paid Bioasis $1.2 million upon closing of the Second Bioasis Royalty Purchase Agreement for the purchased rights.

At the inception of the Second Bioasis Royalty Purchase Agreement, the Company recorded $1.2 million as long-term royalty receivables in its consolidated balance sheet. The Company continues to assess that no payments are probable to be received under the Second Bioasis Royalty Purchase Agreement in the near term. Under the cost recovery method, the Company does not expect to recognize any income related to milestones and other payments until the investment has been fully collected. The Company performed its quarterly impairment assessment and no impairment indicators were identified. Accordingly, no impairment was recorded as of December 31, 2020.

Royalty Purchase Agreement with Aronora, Inc.

On April 7, 2019, the Company entered into a royalty purchase agreement (the “Aronora Royalty Purchase Agreement”) with Aronora, Inc. (“Aronora”), which closed on June 26, 2019. Under the Aronora Royalty Purchase Agreement, the Company purchased from Aronora the right to receive future royalties and a portion of upfront, milestone, and option payments (the “Non-Royalties”) related to five anti-thrombotic hematology drug candidates. Three candidates were subject to Aronora’s collaboration with Bayer Pharma AG (“Bayer”) (the “Bayer Products”), including one which was subject to an exclusive license option by Bayer. The Company will receive 100% of future royalties and 10% of future Non-Royalties from these Bayer Products. The other two candidates are unpartnered (the “non-Bayer Products”) for which the Company will receive low single-digit percentage of net sales and 10% of Non-Royalties. The future payment percentage for Non-Royalties will be reduced from 10% to 5% upon the Company’s receipt of two times the total cumulative amount of consideration paid by the Company to Aronora. In July 2020, Bayer elected to not exercise its option on the third Bayer Product and that product is now subject to the same economics as the non-Bayer Products.

Under the terms of the Aronora Royalty Purchase Agreement, the Company paid Aronora a $6.0 million upfront payment at the close of the transaction. The Company financed $3.0 million of the upfront payment with a term loan under its Loan and Security Agreement with SVB (Note 8). The Company was required to make a contingent future cash payment of $1.0 million for each of the three Bayer Products that were active on September 1, 2019 (up to a total of $3.0 million, the “Aronora Contingent Consideration”). Pursuant to the Aronora Royalty Purchase Agreement, if the Company receives $250.0 million in cumulative royalties on net sales per product, the Company will be required to pay associated tiered milestone payments to Aronora in an aggregate amount of up to $85.0 million per product (the “Royalty Milestones”). The Royalty Milestones are paid based upon various royalty tiers prior to reaching $250.0 million in cumulative royalties on net sales per product. Royalties per product in excess of $250.0 million are retained by the Company.

At the inception of the agreement, the Company recorded $9.0 million as long-term royalty receivables in its consolidated balance sheet, including the estimated fair value of the Aronora Contingent Consideration of $3.0 million. In September 2019, the Company paid the $3.0 million contingent consideration to Aronora. As the Company receives royalties from Aronora for a product, the Company will recognize the liability for future Royalty Milestones for such product when probable and estimable. The Company continues to assess that no payments are probable to be received under this agreement in the near term.

Under the cost recovery method, the Company does not expect to recognize any income related to milestones and royalties received until the investment has been fully collected. The Company performed its quarterly impairment assessment and no impairment indicators were identified. Accordingly, no impairment was recorded as of December 31, 2020. 

Royalty Purchase Agreement with Palobiofarma, S.L.

On September 26, 2019, the Company entered into a royalty purchase agreement (the “Palo Royalty Purchase Agreement”) with Palobiofarma, S.L. (“Palo”), a company organized and existing under the laws of Spain. Pursuant to the Palo Royalty Purchase Agreement, the Company acquired the rights to potential royalty payments in low single-digit percentages of aggregate Net Sales (as defined in the Palo Royalty Purchase Agreement) associated with six drug candidates in various clinical development stages, targeting the adenosine pathway with potential applications in solid tumors, non-Hodgkin’s lymphoma, asthma/chronic obstructive pulmonary disease, ulcerative colitis, idiopathic pulmonary fibrosis, lung cancer, psoriasis and nonalcoholic steatohepatitis and other indications (the “Palo Licensed Products”) that are being developed by Palo. Novartis is a development partner on NIR178, one of the Palo Licensed Products, and NIR178 is being developed pursuant to a license agreement between Palo and Novartis.

Under the terms of the Palo Royalty Purchase Agreement, the Company paid Palo a $10.0 million payment at the close of the transaction which occurred simultaneously upon parties’ entry into the Palo Royalty Purchase Agreement on September 26, 2019. The Company financed $5.0 million of the payment with a term loan under its Loan and Security Agreement with SVB (Note 8).

At the inception of the agreement, the Company recorded $10.0 million as long-term royalty receivables in its consolidated balance sheet. The Company continues to assess that no payments are probable to be received under this agreement in the near term. Under the cost recovery method, the Company does not expect to recognize any income related to royalties received until the investment has been fully collected.

6. Fair Value Measurements

The Company records its financial assets and liabilities at fair value. The carrying amounts of certain of the Company’s financial instruments, including cash, trade receivables, net and accounts payable, approximate their fair value due to their short maturities. Fair value is defined as the exchange price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The accounting guidance for fair value establishes a framework for measuring fair value and a fair value hierarchy that prioritizes the inputs used in valuation techniques. The accounting standard describes a fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value which are the following:

Level 1 – Observable inputs, such as quoted prices in active markets for identical assets or liabilities.

Level 2 – Observable inputs, either directly or indirectly, other than quoted prices in active markets for identical assets or liabilities, such as quoted prices in active markets for similar assets or liabilities, quoted prices in markets that are not active or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3 – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities; therefore, requiring an entity to develop its own valuation techniques and assumptions.

The following tables set forth the Company’s fair value hierarchy for its financial assets and liabilities measured at fair value on a recurring basis as follows (in thousands):

The equity securities consisted of an investment in Rezolute’s common stock and are classified as long-term assets on the consolidated balance sheet as of December 31, 2020 and 2019. The equity securities are revalued each reporting period with changes in fair value recorded in the other income (expense), net line item of the consolidated statements of operations and comprehensive loss.

As of December 31, 2020, the Company and its valuation specialist valued the equity securities using the closing price for Rezolute’s common stock traded on the Nasdaq Stock Market and adjusted for an illiquidity discount. The inputs used to calculate the illiquidity discount are based on observable and unobservable estimates and judgments and therefore is classified as a Level 3 fair value measurement. As the Company has the right and option to sell up to 100,000 of Rezolute’s common stock back to Rezolute after December 31, 2019 (Note 4), the fair value of the equity securities was determined by dividing the total shares of Rezolute’s common stock held by the Company into two tranches based on the estimated time to a potential liquidity event.

The estimated fair value of the equity securities was calculated based on the following assumptions as of December 31, 2020 and December 31, 2019:

Changes in any of the assumptions related to the unobservable inputs identified above may change the fair value of the equity securities.

Contingent Consideration

The estimated fair value of the contingent consideration liability at the inception of the Bioasis Royalty Purchase Agreement represents the future consideration that is contingent upon the achievement of specified development milestones for a product candidate. The fair value measurement is based on significant Level 3 inputs such as anticipated timelines and probability of achieving development milestones of each licensed product candidate. Changes in the fair value of the liability for contingent consideration will be recorded in the other income (expense), net line item of the consolidated statements of operations and comprehensive loss until settlement. As of December 31, 2020, there were no changes in the estimated fair value of the contingent consideration from its initial value of $0.1 million.

Debt

The estimated fair value of the Company’s outstanding debt is estimated using the net present value of the payments, discounted at an interest rate that is consistent with market interest rates, which is a Level 2 input. The carrying amount and the estimated fair value of the Company’s outstanding long-term debt at December 31, 2020 and 2019, are as follows (in thousands):

7. Lease Agreements

The Company leases one facility in Emeryville, California under an operating lease that expires in February 2023. The Emeryville lease contains an option to early terminate the lease by notifying the landlord on or before February 1, 2020, which expired unexercised. The lease also contains an option to extend the lease for an additional term, however, the Company is not reasonably certain to exercise this option.

The Company also previously leased two facilities in Berkeley, California under operating leases that had remaining lease terms until 2021 and 2023. On December 18, 2019, the Company entered into a Lease Termination Agreement with each of the 7th Street Properties II (“7th Street LP”) and 7th Street Property General Partnership (“7th Street GP”) to early terminate the Company’s two operating leases in Berkeley, California. As a result of the lease terminations the Company was also released from all financial obligations under its sublease agreements. The Company agreed to pay an early termination fee of $1.6 million in total and recognized a loss on lease termination of $0.4 million for the year ended December 31, 2019, which was included in other income (expense), net in the consolidated statements of operations and comprehensive loss.

8. Long-Term Debt and Other Financings

Silicon Valley Bank Loan Agreement

On May 7, 2018 (the “Effective Date”), the Company executed a loan and security agreement (the “Loan Agreement”) with SVB. Under the Loan Agreement, upon the Company’s request, SVB made advances (each, a “Term Loan Advance”) available to the Company up to $20.0 million (the “Term Loan”). The Company was allowed to borrow advances under the Term Loan from the Effective Date until the earlier of March 31, 2019 or an event of default (the “Draw Period”). In March 2019, the Draw Period was extended from March 31, 2019 to March 31, 2020. In the event of a default related to the Note Agreement with Novartis, SVB’s obligation to make any credit extensions to the Company

Table of Contents

under the Loan Agreement will immediately terminate. The interest rate will be calculated at a rate equal to the greater of (i) 4.75%, or (ii) 0.25% plus the prime rate as reported from time to time in The Wall Street Journal.

Payments under the Loan Agreement are interest only until the first anniversary of the funding date of each Term Loan Advance. The interest-only period will be followed by equal monthly payments of principal and interest over 24 months. Each Term Loan Advance will mature at the earlier of (i) the 23 months following the applicable term loan amortization date for each such Term Loan Advance (ii) March 1, 2023, or (iii) 30 days prior to the earliest maturity of any portion of the Company’s loan with Novartis (the “Loan Maturity Date”). After repayment, no Term Loan Advance (or any portion thereof) may be reborrowed.

The entire principal balance, including a final payment fee equal to 8.5% of the principal, will be due and payable on the Loan Maturity Date. If the Company prepays the Term Loan Advance prior to the Loan Maturity Date, it will pay SVB a prepayment premium, based on a prepayment fee equal to 3.00% of the amount prepaid, if the prepayment occurs on or before the first anniversary of the Effective Date, 2.00% of the amount prepaid, if the prepayment occurs after the first anniversary of the Effective Date but prior to the second anniversary of the Effective Date, and 1.00% of the amount prepaid if the prepayment occurs after the second anniversary of the Effective Date. In the event of a default, a default interest rate of an additional 4% may be applied to the outstanding payments due to SVB, and SVB may declare all outstanding obligations immediately due and payable and take such other actions as set forth in the Loan Agreement.

The Company’s obligations under the Loan Agreement are secured by a security interest in substantially all of its assets, other than its intellectual property. The Loan Agreement includes customary affirmative and restrictive covenants, but does not include any financial maintenance covenants, and also includes standard events of default, including payment defaults.

In connection with the Loan Agreement, the Company issued a warrant to SVB which is exercisable in whole or in part for up to an aggregate of 6,332 shares of common stock with an exercise price of $23.69 per share (the “Warrant”). The Warrant may be exercised on a cashless basis and is exercisable within 10 years from the date of issuance or upon the consummation of certain acquisitions of the Company. The fair value of the Warrant issued to SVB was determined using the Black-Scholes Model and was estimated to be $0.1 million. In addition, the Company incurred debt issuance costs of $0.2 million in connection with the Loan Agreement.

On March 4, 2019, the Loan Agreement was amended to extend the Draw Period from March 31, 2019 to March 31, 2020. In connection with the amendment, the Company issued a second warrant to SVB which is exercisable in whole or in part for up to an aggregate of 4,845 shares of common stock with an exercise price of $14.71 per share. The fair value of the second warrant issued to SVB was determined using the Black-Scholes Model and was estimated to be $0.1 million.

As of December 31, 2020, both warrants are outstanding. In addition, both warrants may be exercised on a cashless basis and are exercisable within 10 years from the date of issuance or upon the consummation of certain acquisitions of the Company.

In September 2018, the Company borrowed advances of $7.5 million under the Loan Agreement in connection with the Agenus Royalty Purchase Agreement (Note 5). The Company recorded a discount of $0.3 million against the debt, which is being amortized to interest expense over the term of the Term Loan Advance using the effective interest method.   

During the year ended December 31, 2019, the Company borrowed advances totaling $9.5 million under the Loan Agreement in connection with the Aronora Royalty Purchase Agreement, Palo Royalty Purchase Agreement and payment of the Aronora Contingent Consideration (Note 5). The Company recorded a discount of $45,000 against the debt, which is being amortized to interest expense over the term of the Term Loan Advance using the effective interest method.

The Company recorded $0.6 million and $0.5 million of non-cash interest expense resulting from the amortization of the discount and accretion of the final payment for the years ended December 31, 2020 and 2019, respectively.

Table of Contents

As of December 31, 2020, the carrying value of the debt under the Loan Agreement was $11.8 million. Of this amount, $8.1 million is classified as current portion of long-term debt and $3.7 million is classified as long-term debt on the consolidated balance sheet. As of December 31, 2019, the carrying value of the debt under the Loan Agreement was $16.4 million. Of this amount, $5.2 million was classified as current portion of long-term debt and $11.2 million was classified as long-term debt on the consolidated balance sheet.

Novartis Note

In May 2005, the Company executed a secured note agreement (the “Note Agreement”) with Novartis, which was due and payable in full in June 2015. Under the Note Agreement, the Company borrowed semi-annually to fund up to 75% of the Company’s research and development and commercialization costs under its collaboration arrangement with Novartis, not to exceed $50.0 million in aggregate principal amount. Interest on the principal amount of the loan accrues at six-month LIBOR plus 2%, which was equal to 2.26% at December 31, 2020. The interest is payable semi-annually in June and December of each year or, at the Company’s election, the semi-annual interest payments may be added to the outstanding principal amount, in lieu of a cash payment, as long as the aggregate principal amount does not exceed $50.0 million. The Company made this election for all interest payments. Loans under the Note Agreement are secured by the Company’s interest in its collaboration with Novartis, including any payments owed to it thereunder.

On September 30, 2015, concurrent with the execution of a license agreement with Novartis International as discussed in Note 4, XOMA and NIBR, who assumed the rights to the note from Novartis Vaccines Diagnostics, Inc. executed an amendment to the Note Agreement (the “Secured Note Amendment”) under which the parties extended the maturity date of the note from September 30, 2015 to September 30, 2020, and eliminated the mandatory prepayment previously required to be made with certain proceeds of pre-tax profits and royalties. In addition, upon achievement of a specified development and regulatory milestone, the then-outstanding principal amount of the note was to be reduced by $7.3 million rather than the Company receiving such amount as a cash payment.

On September 22, 2017, in connection with the Gevokizumab License Agreement with Novartis, the Company and NIBR executed an amendment to the Secured Note Amendment under which the parties further extended the maturity date of the Secured Note Amendment from September 30, 2020 to September 30, 2022.

On October 21, 2020, the first patient was dosed in Novartis International’s NIS793 Phase 2 clinical trial and we earned a $25.0 million milestone payment pursuant to the Anti-TGFβ Antibody License Agreement, of which $7.3 million was recognized as a reduction to the debt obligation to Novartis.

As of December 31, 2020 and 2019, the outstanding principal balance under the Secured Note Amendment was $9.1 million and $15.9 million, respectively, and was included in long-term debt in the accompanying consolidated balance sheet.

On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security (“CARES”) Act was enacted, which includes a five-year net operating loss (“NOL”) carryback provision which enabled the Company to benefit from certain losses at the former federal tax rate of 34%. In 2020, the Company recorded tax benefits of $1.5 million related to the NOL carryback provision.

The Consolidated Appropriations Act was also signed into law on December 27, 2020 to provide further relief measures and renew various expiring tax provisions. The Company does not expect there is material impact to its income tax expenses.

The net decrease in the valuation allowance was $3.9 million and $2.0 million, for the years ended December 31, 2020 and 2019, respectively.

Accounting standards provide for the recognition of deferred tax assets if realization of such assets is more likely than not. Based upon the weight of available evidence, which includes the Company’s four sources of taxable income including historical operating performance and the repeal of net operating loss carryback, the Company has determined that total deferred tax assets should be fully offset by a valuation allowance.

Based on an analysis under Section 382 of the Internal Revenue Code (which subjects the amount of pre-change NOLs and certain other pre-change tax attributes that can be utilized to annual limitations), the Company experienced an ownership change in February 2017 which substantially limits the future use of its pre-change NOLs and certain other pre-change tax attributes per year. The Company has excluded the related tax attributes that will expire as a result of the annual limitations in the deferred tax assets as of December 31, 2020 and December 31, 2019. To the extent that the Company does not utilize its carry-forwards within the applicable statutory carryforward periods, either because of Section 382 limitations or the lack of sufficient taxable income, the carryforwards will expire unused.

As of December 31, 2020, the Company had federal net operating loss carry-forwards of approximately $78.6 million and state net operating loss carry-forwards of approximately $38.3 million to offset future taxable income. $13.6 million of federal net operating loss carryforwards will begin to expire in 2036 and the remainder may be carried forward

indefinitely. The state net operating loss carryforwards will begin to expire in 2033. The Company had federal orphan credit of $2.3 million which if not utilized will expire in 2037. The Company also had $19.8 million of California research and development tax credits which have no expiration date.

Under the 2017 federal income tax law, as modified by the federal tax law changes enacted in March 2020, federal net operating losses incurred in tax years beginning after December 31, 2017 may be carried forward indefinitely, but, for taxable years beginning after December 31, 2020, the deductibility of such federal net operating losses may only be utilized to offset 80% of taxable income annually.  

The Company files income tax returns in the U.S. federal jurisdiction and various states. The Company’s federal income tax returns for tax years 2017 and beyond remain subject to examination by the Internal Revenue Service. The Company’s state income tax returns for tax years 2016 and beyond remain subject to examination by state tax authorities. In addition, all of the net operating losses and research and development credit carry-forwards that may be used in future years are still subject to adjustment.

As of December 31, 2020, the Company had a total of $5.9 million of gross unrecognized tax benefits, none of which would affect the effective tax rate upon realization. The Company currently has a full valuation allowance against its U.S. net deferred tax assets, which would impact the timing of the effective tax rate benefit should any of these uncertain tax positions be favorably settled in the future.

The Company does not expect its unrecognized tax benefits to change significantly over the next twelve months. The Company will recognize interest and penalties accrued on any unrecognized tax benefits as a component of income tax expense. Through December 31, 2020, the Company has not accrued interest or penalties related to uncertain tax positions.

10. Compensation and Other Benefit Plans

The Company grants qualified and non-qualified stock options, RSUs, common stock and other stock-based awards under various plans to directors, officers, employees and other individuals. Stock options are granted at exercise prices of not less than the fair market value of the Company’s common stock on the date of grant. Additionally, the Company has an Employee Stock Purchase Plan (“ESPP”) that allows employees to purchase Company shares at a purchase price equal to 85% of the lower of the fair market value of the Company’s common stock on the first trading day of the offering period or on the last day of the offering period.

Employee Stock Purchase Plan

In May 2015, the Company’s stockholders approved the 2015 Employee Stock Purchase Plan (the “2015 ESPP”), which replaced the Company’s legacy 1998 ESPP. Under the 2015 ESPP, the Company reserved 15,000 shares of common stock for issuance as of its effective date of July 1, 2015, subject to adjustment in the event of a stock split, stock dividend, combination or reclassification or similar event. The 2015 ESPP allows eligible employees to purchase shares of the Company’s common stock at a discount through payroll deductions of up to 10% of their eligible compensation, subject to any plan limitations. The 2015 ESPP provides for six-month offering periods ending on May 31 and November 30 of each year. At the end of each offering period, employees are able to purchase shares at 85% of the lower of the fair market

F-35

Table of Contents

value of the Company’s common stock on the first trading day of the offering period or on the last day of the offering period.

In February 2017, the Compensation Committee and the Board of Directors adopted, and in May 2017, the Company’s stockholders approved, an amendment to the Company’s 2015 ESPP. The amendment (a) increased by 250,000 the shares of common stock (from 15,000 shares to a total of 265,000 shares) available for issuance under the 2015 ESPP; and (b) increased the maximum number of shares of common stock an employee may purchase in any offering period to 2,500.

During the years ended December 31, 2020 and 2019, employees purchased 2,746 and 2,365 shares of common stock, respectively, under the 2015 ESPP.

Deferred Savings Plan

Under section 401(k) of the Internal Revenue Code of 1986, the Board of Directors adopted, effective June 1, 1987, a tax-qualified deferred compensation plan for employees of the Company. Participants may make contributions which defer up to 50%of their eligible compensation per payroll period, up to a maximum for 2020 of $19,500 (or $26,000 for employees over 50 years of age) and for 2019 of $19,000 (or $25,000 for employees over 50 years of age). The Company may, at its sole discretion, make contributions each plan year, in cash or in shares of the Company’s common stock, in amounts which match up to 50% of the salary deferred by the participants. The expense related to these contributions was $0.1 million for the years ended December 31, 2020 and December 31, 2019, respectively, and 100% was paid in common stock for each year. The Company applies shares from plan forfeitures of terminated employees toward the Company’s matching contribution.  

Stock Option Plans

In May 2010, the Compensation Committee and the full Board adopted, and in July 2010 the Company’s stockholders approved, a new equity-based compensation plan, the 2010 Long Term Incentive and Share Award Plan, which has since been amended and restated as the Amended and Restated 2010 Long Term Incentive and Stock Award Plan (the “2010 Plan”). The 2010 Plan replaced the Company’s legacy Option Plan, Restricted Plan and 1992 Directors Share Option Plan (the “Directors Plan”) and provided a more current set of terms under which to provide this type of compensation.

In February 2016, the Compensation Committee and the Board of Directors adopted, and in May 2016, the Company’s stockholders approved an amendment to the 2010 Plan to, among other things, allow for an increase in the number of shares of common stock reserved for issuance by 170,000 shares to an aggregate of 1,108,560 shares.

In February 2017, the Compensation Committee and the Board of Directors adopted, and in May 2017, the Company’s stockholders approved, an amendment to the 2010 Plan. The amendment (a) increases the number of shares of common stock issuable over the term of the plan by an additional 1,470,502 to 2,579,062 shares in the aggregate; (b) increases the number of shares of common stock issuable under the plan as incentive stock options by an additional 2,004,087 to 2,579,062 shares; (c) increases the per person award limits for purposes of compliance with Section 162(m) of the Internal Revenue Code to 2,000,000 shares for options and stock appreciation rights and to 2,000,000 shares for other types of stock awards; and (d) for purposes of Section 162(m) (i) confirms existing performance criteria upon which performance goals may be based with respect to performance awards under the 2010 Plan, and (ii) confirms existing means of adjustment when calculating the attainment of performance goals for performance awards granted under the 2010 Plan.

In May 2019, the Compensation Committee and the Board of Directors adopted, and in May 2019, the Company’s stockholders approved, an amendment to the 2010 Plan. The amendment (a) increases the number of shares of common stock issuable over the term of the plan by an additional 450,000 to 3,029,062 shares in the aggregate; (b) increases the number of shares of common stock issuable under the plan as incentive stock options by an additional 450,000 to 3,029,062 shares; (c) extended the term of the Plan until April 1, 2029; (d) for purposes of Section 162(m) (i) eliminates performance cash awards, and (ii) eliminates individual grant limits that applied under the 2010 Long Term Incentive Plan to awards that were intended to comply with the exemption for “performance-based compensation” under Code Section 162(m).

F-36

Table of Contents

From the 2010 Plan, the Company grants stock options, RSUs, and other stock-based awards to eligible employees, consultants and directors. No further grants or awards will be made under the Option Plan, the Restricted Share Plan or the Directors Plan. Shares underlying options previously issued under the Option Plan, the Restricted Share Plan or the Directors Plan that are currently outstanding will, upon forfeiture, cancellation, surrender or other termination, become available under the 2010 Plan. Stock-based awards granted under the 2010 Plan may be exercised when vested and generally expire ten years from the date of the grant or three to six months from the date of termination of employment (longer in case of death or certain retirements).

As of December 31, 2020, the Company had 321,716 shares available for grant under the stock option plan. As of December 31, 2020, options covering 1,827,906 shares of common stock were outstanding under the stock option plan.

Stock Options

Stock options generally vest monthly over three years for employees and one year for directors. Stock options held by employees who qualify for retirement age (defined as employees that are a minimum of 55 years of age and the sum of their age plus years of full-time employment with the Company exceeds 70 years) vest on the earlier of scheduled vest date or the date of retirement.

The aggregate intrinsic value of stock options exercised in 2020 and 2019 was $5.4 million and $0.7 million, respectively.

The weighted-average grant-date fair value per share of the options granted in 2020 and 2019 was $18.41 and $11.72, respectively.

As of December 31, 2020, $3.6 million of total unrecognized compensation expense related to stock options is expected to be recognized over a weighted average period of 1.67 years.

Performance-Based Stock Options

Stock-based compensation expense associated with the corporate performance-based stock options is recognized if the performance condition is considered probable of achievement using management’s best estimates. In 2017, the Company granted performance-based stock options with vesting criteria related to performance in 2017, 2018, and 2019. In 2019, the Company had 41,250 shares remaining related to outstanding performance-based stock options with a grant date fair value of $0.2 million that had vesting criteria based solely on the achievement of fiscal year 2019 corporate goals as set by the Compensation Committee of the Company’s Board of Directors. For the year ended December 31, 2019, the Company determined that all remaining performance criteria were achieved and therefore the related expense of $0.2

million was recognized for the year ended December 31, 2019. After December 31, 2019, no performance-based stock options were outstanding and there was no unrecognized compensation cost related to performance-based stock options.

Modification of Stock Options

In September 2019, the Company entered into a separation agreement with its former Chief Business Officer which resulted in the extension of the exercise period for all her vested options. As a result of the modification, the Company recorded stock-based compensation expense of $0.5 million during the year to reflect the revised expected term based on the modified exercise period for these stock options in 2019. There were no modifications of stock options during the year ended December 31, 2020.

Stock-based Compensation Expense

The fair value of stock options granted during the years ended December 31, 2020 and 2019, was estimated based on the following weighted average assumptions for:

Preferred Stock

Series A Preferred Stock

On December 15, 2020, the Company sold 984,000 shares of its 8.625% Series A cumulative, perpetual preferred stock at the price of $25.00 per share, through a public offering for aggregate gross proceeds of $24.6 million. Total offering costs of $2.0 million were offset against the proceeds from the sale of Series A Preferred Stock, for total net proceeds of $22.6 million.

Mr. Matthew Perry, a member of the Company’s Board of Directors and President of Biotechnology Value Fund, L.P. (“BVF”), purchased 200,000 shares of Series A Preferred Stock in the public offering at the public offering price of $25.00 per share for an aggregate amount of $5.0 million. The spouse of James Neal, the Company’s Chief Executive Officer and a director, purchased 8,000 shares of the Series A Preferred Stock in the public offering at the public offering price of $25.00 per share for an aggregate amount of $0.2 million.

As of December 31, 2020, there were 984,000 shares authorized and issued of Series A Preferred Stock. As of December 31, 2020, the Company held restricted cash of $2.1 million in a segregated account that may only be used to pay dividends on the Series A Preferred Stock. As of December 31, 2020, the current and non-current portion of restricted cash was $1.6 million and $0.5 million, respectively.

The Series A preferred stock have the following characteristics, which are set forth in Certificates of Designation of Preferences, Rights and Limitations filed with the Delaware Secretary of State.

Dividends— Holders of the Series A Preferred Stock shall be entitled to receive, when, as and if authorized by the Board of Directors and declared by the Corporation, cumulative cash dividends at the rate of 8.625% per annum of the $25.00 liquidation preference per share of the Series A Preferred Stock. Such dividends will accumulate and be cumulative from, and including, the date of original issue of the Series A preferred stock. Dividends will be payable in arrears on or about the 15th day of January, April, July and October of each year beginning on or about April 15, 2021. The amount of

F-39

Table of Contents

any dividend payable on the Series A Preferred Stock for any period greater or less than a full Dividend Period shall be prorated and computed on the basis of a 360-day year consisting of twelve 30-day months. 

Liquidation Rights— In the event of the Company’s liquidation, dissolution or winding up, holders of Series A Preferred Stock will rank senior to all classes or series of common stock as to dividend rights and rights upon liquidation, dissolution or winding-up and on parity with respect to the distribution of assets with the Company’s Series X Preferred Stock. The Series A Preferred Stock have a par value of $0.05 per share and a liquidation preference of $25.00 per share plus any accrued and unpaid dividends.

Redemption and Special Optional Redemption— The Company, at its option, may redeem the Series A Preferred Stock, in whole or in part, at any time for a cash redemption price, plus any accrued and unpaid dividends, as follows: (i) $26.00 per share between December 15, 2021 and December 15, 2022, (ii) $25.75 per share between December 15, 2022 and December 15, 2023, (iii) $25.50 per share between December 15, 2023 and December 15, 2024 (iv) $25.25 per share between December 15, 2024 and December 15, 2025 and $25.00 per share on or after December 15, 2025. The Company also has a special optional redemption option whereby, upon the occurrence of a delisting event or change of control event, the Company may redeem outstanding Series A Preferred Stock at an amount of $25.00 per share.

Conversion— The shares of Series A Preferred Stock are not convertible into or exchangeable for any other property or securities of the Company except upon the occurrence of a delisting event or change in control event and the Company has not, on or before the date of such an event, provided the required notice of its election to redeem the Series A Preferred Stock pursuant to its redemption right or special optional redemption right. In this case, the holder of Series A preferred shares can convert some or all of their Series A Preferred Stock into a number of shares of common stock per share equal to the lesser of (A) (i) the sum of the $25.00 liquidation preference per share of Series A Preferred Stock to be converted plus (y) the amount of any accrued and unpaid dividends to, but not including, the event date, as applicable by (ii) the common stock price and (B) 1.46071 (the “Share Cap”). The common stock price to be used in the latter noted calculation for a delisting event will be the average of the closing price per share of the Company’s common stock on the 10 consecutive trading days immediately preceding, but not including, the effective date of the delisting event. The common stock price used in the event of a change in control event will, alternatively, be based on market price according to the definition in the Certificate of Designation.

Voting Rights— Holders of the Series A Preferred Stock generally will have no voting rights, but will have limited voting rights if the issuer fails to pay dividends for six or more quarters (whether or not declared or consecutive) and in certain other events.

Classification—The Company evaluated the convertible preferred stock for liability or equity classification under the applicable accounting guidance and determined that treatment as equity was appropriate.

Each share is convertible at the option of the holder at any time, provided that the holder will be prohibited from converting into common stock if, as a result of such conversion, the holder, together with its affiliates, would beneficially own a number of shares above a conversion blocker, which is initially set at 19.99% of the total common stock then issued and outstanding immediately following the conversion of such shares. A holder of Series X or Y preferred shares may elect to increase or decrease the conversion blocker above or below 19.99% on 61 days’ notice, provided the conversion blocker does not exceed the limits under Nasdaq Marketplace Rule 5635(b), to the extent then applicable.

There were 5,003 shares of Series X convertible preferred stock and no shares of Series Y convertible preferred stock outstanding as of December 31, 2020, after BVF converted all Series Y preferred stock into common stock on April 15, 2020. The Series X and Series Y convertible preferred stock have the following characteristics, which are set forth in Certificates of Designation of Preferences, Rights and Limitations filed with the Delaware Secretary of State.

Dividends— Holders of convertible preferred stock are entitled to receive dividends on shares of convertible preferred stock equal (on an as if converted to common stock basis) to and in the same form as dividends actually paid on the Company’s common stock.

Liquidation Rights— In the event of the Company’s liquidation, dissolution or winding up, holders of convertible preferred stock will participate, on a pro-rata basis, with any distribution of proceeds to holders of common stock.

Conversion— Each share of Series X and Series Y is convertible into 1,000 shares of registered common stock based on a conversion price of $4.03 per share and $13.00 per share of common stock, respectively.

Voting Rights— Convertible preferred stock will generally have no voting rights, except as required by law and except that the consent of the holders of the outstanding convertible preferred stock will be required to amend the terms and to issue additional shares of the preferred stock.

Classification— The Company evaluated the convertible preferred stock for liability or equity classification under the applicable accounting guidance and determined that equity treatment was appropriate because the convertible preferred stock did not meet the definition of the liability instruments defined thereunder for convertible instruments. Specifically, the convertible preferred shares are not mandatorily redeemable and do not embody an obligation to buy back the shares outside of the Company’s control in a manner that could require the transfer of assets. Additionally, the Company determined that the convertible preferred stock would be recorded as permanent equity, not temporary equity, given that they are not redeemable for cash or other assets (i) on a fixed or determinable date, (ii) at the option of the holder, and (iii) upon the occurrence of an event that is not solely within control of the Company. The Company has also evaluated the embedded conversion and contingent redemption features within the convertible preferred stock in accordance with the accounting guidance for derivatives and determined that bifurcation is not required for any embedded feature.

Beneficial Conversion Feature— The fair value of the common stock into which the Series X convertible preferred stock is convertible exceeded the allocated purchase price of the Series X convertible preferred stock by $5.6 million on the date of issuance, as such the Company recorded a deemed dividend. The Company recognized the resulting beneficial conversion feature as a deemed dividend equal to the number of shares of Series X convertible preferred stock sold on February 16, 2017 multiplied by the difference between the fair value of the common stock and the Series X convertible preferred stock effective conversion price per share on that date. The dividend was reflected as a one-time, non-cash, deemed dividend to the holders of Series X convertible preferred stock on the date of issuance, which is the date the stock first became convertible. There was no beneficial conversion feature associated with the issuance of Series Y convertible preferred stock.

BVF Ownership

In February 2020, BVF elected to increase the beneficial ownership limitation of the Series Y preferred stock to 50%, which became effective on April 11, 2020. On April 15, 2020, BVF converted all of its shares of Series Y preferred stock into common stock. As of December 31, 2020, BVF owned approximately 37.2% of the Company’s total outstanding shares of common stock, and if all the Series X convertible preferred shares were converted, BVF would own 56.6% of the Company’s total outstanding shares of common stock. The Company’s Series A Preferred Stock becomes convertible upon the occurrence of specific events and as of December 31, 2020 the contingency was not met. Due to its significant equity ownership, BVF is considered a related party of the Company.

2018 ATM Agreement

On December 18, 2018, the Company entered into an At The Market Issuance Sales Agreement (the “2018 ATM Agreement”) with H.C. Wainwright & Co., LLC (“HCW”), under which the Company may offer and sell from time to time at its sole discretion shares of its common stock through HCW as its sales agent, in an aggregate amount not to exceed $30.0 million. HCW may sell the shares by any method permitted by law deemed to be an “at the market” offering as defined in Rule 415 of the Securities Act, and will use its commercially reasonable efforts consistent with its normal trading and sales practices to sell the shares up to the amount specified. The Company will pay HCW a commission of up to 3% of the gross proceeds of any shares of common stock sold under the 2018 ATM Agreement. No shares have been sold under the 2018 ATM Agreement since the agreement was executed.

(“Hercules”) a five-year warrant that entitles Hercules to purchase up to an aggregate of 9,063 unregistered shares of the Company’s common stock at an exercise price equal to $66.20 per share. The warrant was issued in connection with a term loan that was repaid in full in 2017. The warrant is classified in stockholders’ equity on the consolidated balance sheets.

As of December 31, 2020, no shares have been issued upon exercise of the warrant.

In May 2018, the Company issued SVB a warrant in connection with the SVB Loan Agreement (Note 8) which is exercisable in whole or in part for up to an aggregate of 6,332 shares of common stock with an exercise price of $23.69 per share. The warrant may be exercised on a cashless basis and is exercisable within 10 years from the date of issuance or upon the consummation of certain acquisitions of the Company.

In March 2019, the Loan Agreement was amended to extend the Draw Period from March 31, 2019 to March 31, 2020. In connection with the amendment, the Company issued a second warrant to SVB which is exercisable in whole or in part for up to an aggregate of 4,845 shares of common stock with an exercise price of $14.71 per share. The second warrant may be exercised on a cashless basis and is exercisable within 10 years from the date of issuance or upon the consummation of certain acquisitions of the Company. The fair value of the second warrant issued to SVB was determined using the Black-Scholes Model and was estimated to be $0.1 million. As of December 31, 2020, both warrants are outstanding and no shares have been issued upon exercise of the warrants.

13. Commitments and Contingencies

Collaborative Agreements, Royalties and Milestone Payments

The Company has committed to make potential future milestone payments and legal fees to third parties as part of licensing and development programs. Payments under these agreements become due and payable only upon the achievement of certain developmental, regulatory and commercial milestones by the Company’s licensees. Because it is uncertain if and when these milestones will be achieved, such contingencies, aggregating up to $7.6 million (assuming one product per contract meets all milestones events) have not been recorded on the accompanying consolidated balance sheets. The Company is unable to determine precisely when and if payment obligations under the agreements will become due as these obligations are based on milestone events, the achievement of which is subject to a significant number of risks and uncertainties.

Contingent Consideration

Pursuant to the Company’s royalty purchase agreements with Bioasis and Aronora, the Company committed to pay the Bioasis Contingent Consideration, the Aronora Contingent Consideration and the Aronora Royalty Milestones. Upon acquisition, the Company recorded $0.1 million and $3.0 million for the Bioasis Contingent Consideration and the Aronora Contingent Consideration, respectively, which represent the estimated fair value of these potential future payments at the inception of the agreements. These contingent consideration payments are remeasured at fair value at each reporting period, with changes in fair value recorded in other income (expense), net. In September 2019, the Company paid the Aronora Contingent Consideration of $3.0 million. The liability for future Aronora Royalty Milestones will be recorded when the amounts by product are estimable and probable. As of December 31, 2020, none of these Aronora Royalty Milestones were assessed to be probable and as such, none was recorded on the consolidated balance sheet. During the years ended December 31, 2020 and 2019, there was no change to the estimated fair value of the Bioasis Contingent Consideration.

14. Concentration of Risk, Segment and Geographic Information

Concentration of Risk

Cash and receivables are financial instruments which potentially subject the Company to concentrations of credit risk, as well as liquidity risk.  

The Company has not experienced any significant credit losses and does not generally require collateral on receivables. For the year ended December 31, 2020, one partner represented 85% of total revenues. For the year ended December 31, 2019, two partners represented 76% and 14% of total revenues. As of December 31, 2020 and 2019, one partner represented 100% of the trade receivables balance.

Segment Information

Exhibit 4.6

 DESCRIPTION OF XOMA CORPORATION CAPITAL STOCK

The following is a description of the Common Stock, $0.0075 par value (the “Common Stock”) and Preferred Stock, $0.05 par value (the “Preferred Stock”) of XOMA Corporation (the “Company”). The Common Stock and the 8.625% Series A Cumulative Perpetual Preferred Stock (the “Series A Preferred Stock”) are the only securities of the Company registered pursuant to Section 12 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

Common Stock

General. The Company is authorized to issue up to 277,333,332 shares of Common Stock. The following description is based on (i) the Company’s Certificate of Incorporation, as currently in effect (the “Certificate of Incorporation”), (ii) the Company’s By-laws, as currently in effect (the “By-laws”), and (iii) the Delaware General Corporation Law (the “DGCL”). The following summary description of the Common Stock of the Company is qualified in its entirety by reference to the provisions of the Certificate of Incorporation and By-laws, copies of which have been filed as exhibits to the Company’s Annual Report filed herewith, and the applicable provisions of the DGCL.

Dividend Rights. The holders of our Common Stock have the right to receive dividends and distributions, whether payable in cash or otherwise, as may be declared from time to time by our board of directors, from legally available funds.

Voting Rights. Each holder of our Common Stock is generally entitled to one vote for each share of Common Stock owned of record on all matters submitted to a vote of our stockholders. Except as otherwise required by law, holders of Common Stock (as well as holders of any Preferred Stock entitled to vote with the common stockholders) will generally vote together as a single class on all matters presented to the stockholders for their vote or approval, including the election of directors. Any matter brought before the stockholders for a vote, other than the election of directors, will generally be decided by a majority of the votes cast on the matter, unless the matter is one in which an express provision of the DGCL, the Certificate of Incorporation, the By-laws, the rules or regulations of any stock exchange applicable to us, applicable law or pursuant to any regulation applicable to us or our securities requires a different vote, in which case the express provision will govern and control the decision of the matter. Directors will be elected by a plurality of the votes cast and entitled to vote generally on the election of directors. There are no cumulative voting rights with respect to the election of directors or any other matters.

No Preemptive or Similar Rights. Holders of our Common Stock have no redemption rights, conversion rights or preemptive rights to purchase or subscribe for our securities.

Right to Receive Liquidation Distributions. In the event of our liquidation, dissolution or winding-up, holders of our Common Stock will be entitled to share equally in the assets available for distribution after payment of all creditors and the liquidation preferences of our Preferred Stock (if any).

The rights of the holders of our Common Stock are subject to, and may be adversely affected by, the rights of holders of shares of any Preferred Stock that we may designate and issue in the future.

Preferred Stock

General. Under our Certificate of Incorporation, our board of directors is authorized to issue up to 1,000,000 shares of Preferred Stock, and, by resolution, to divide the Preferred Stock into series and, with respect to each series, to determine the designations and the powers, preferences and rights, and the qualifications, limitations and restrictions thereof, including the dividend rights, conversion or exchange rights, voting rights, redemption rights and terms, liquidation preferences, sinking fund provisions and the number of shares constituting the series. Our board of directors can, without stockholder approval but subject to the terms of the Certificate of Incorporation and to any resolution of the stockholders approved by at least 75% of all issued shares entitled to vote in respect thereof, issue


Preferred Stock with voting and other rights that could adversely affect the voting power of the holders of our Common Stock and which could have certain anti-takeover effects. Before we may issue any series of Preferred Stock, our board of directors will be required to adopt resolutions creating and designating such series of Preferred Stock.

The following summary description of the Preferred Stock of the Company is qualified in its entirety by reference to the provisions of the Certificate of Incorporation, By-laws and the certificates of designation of preferences, rights and limitations of each series of the Preferred Stock, copies of which have been filed as exhibits to the Company’s Annual Report on Form 10-K, and the applicable provisions of the DGCL. As of December 31, 2020, 5,003 shares of Series X Preferred Stock and 984,000 shares of 8.625% Series A Cumulative Perpetual Preferred Stock (the “Series A Preferred Stock”) were issued and outstanding.

The 8.625% Series A Cumulative Perpetual Preferred Stock. We have designated 984,000 shares of our Preferred Stock as Series A Preferred Stock.

The Series A Preferred Stock will rank, as to dividend rights and rights upon our liquidation, dissolution or winding up:

senior to all classes or series of our common stock and to all other equity securities issued by us expressly designated as ranking junior to the Series A Preferred Stock;

senior with respect to the payment of dividends and on parity with respect to the distribution of assets upon our liquidation, dissolution or winding up with our Series X Preferred Stock and on parity with any future class or series of our equity securities expressly designated as ranking on parity with the Series A Preferred Stock;

junior to all equity securities issued by us with terms specifically providing that those equity securities rank senior to the Series A Preferred Stock with respect to the payment of dividends and the distribution of assets upon our liquidation, dissolution or winding up, none of which exists on the date hereof; and;

effectively junior to all our existing and future indebtedness (including indebtedness convertible into our common stock or preferred stock) and to the indebtedness and other liabilities of (as well as any preferred equity interests held by others in) our existing or future subsidiaries.

Dividends.  We will pay cumulative cash dividends on the Series A Preferred Stock, when and as declared by our board of directors, at the rate of 8.625% of the $25.00 liquidation preference per share per year (equivalent to $2.15625 per year). Dividends will be payable quarterly in arrears, on or about the 15th day of January, April, July and October, beginning on or about April 15, 2021; provided that if any dividend payment date is not a business day, then the dividend which would otherwise have been payable on that dividend payment date may be paid on the next succeeding business day, and no interest, additional dividends or other sums will accumulate. Dividends will accumulate and be cumulative from, and including, the date of original issuance, which is expected to be December 15, 2020. The first dividend, which is scheduled to be paid on or about April 15, 2021 in the amount of $0.71875 per share of Series A Preferred Stock, will be for more than a full quarter and will cover the period from, and including, the first date we issue and sell the Series A Preferred Stock through, but not including, April 15, 2021. Dividends on the Series A Preferred Stock will continue to accumulate whether or not (i) any of our agreements prohibit the current payment of dividends, (ii) we have earnings or funds legally available to pay the dividends, or (iii) our board of directors does not declare the payment of the dividends.

Liquidation Preference. The liquidation preference of each share of Series A Preferred Stock is $25.00. Upon liquidation, holders of our Series A Preferred Stock will be entitled to receive the liquidation preference with respect to their shares of Series A Preferred Stock plus an amount equal to accumulated but unpaid dividends with respect to such shares.

Optional Redemption. On and after December 15, 2021, the first anniversary of December 15, 2020, to but excluding the second anniversary, the shares of Series A Preferred Stock will be redeemable at our option, in whole or in part, at a redemption price equal to $26.00 per Preferred Share, plus any accrued and unpaid dividends. On and


after December 15, 2022, the second anniversary of December 15, 2020, to but excluding the third anniversary, the shares of Series A Preferred Stock will be redeemable at our option, in whole or in part, at a redemption price equal to $25.75 per Preferred Share, plus any accrued and unpaid dividends. On and after December 15, 2023, the third anniversary of December 15, 2020, to but excluding the fourth anniversary, the shares of Series A Preferred Stock will be redeemable at our option, in whole or in part, at a redemption price equal to $25.50 per Preferred Share, plus any accrued and unpaid dividends. On and after December 15, 2024, the fourth anniversary of December 15, 2020, to but excluding the fifth anniversary, the shares of Series A Preferred Stock will be redeemable at our option, in whole or in part, at a redemption price equal to $25.25 per Preferred Share, plus any accrued and unpaid dividends. On and after December 15, 2025, the fifth anniversary of December 15, 2020, the shares of Series A Preferred Stock will be redeemable at our option, in whole or in part, at a redemption price equal to $25.00 per Preferred Share, plus any accrued and unpaid dividends. We may not redeem the shares of Series A Preferred Stock before the first anniversary of December 15, 2020, except as described below.

Special Optional Redemption Upon a Change of Control or Delisting Event. Upon the occurrence of a Delisting Event (as defined below), we may, at our option, redeem the Series A Preferred Stock, in whole or in part, within 90 days after the first date on which such Delisting Event occurred, for cash, at a redemption price of $25.00 per share, plus any accrued and unpaid dividends up to, but not including, the date of redemption.

A “Delisting Event” occurs when, after the original issuance of Series A Preferred Stock, both (i) the shares of Series A Preferred Stock are no longer listed on Nasdaq, the New York Stock Exchange (the “NYSE”) or the NYSE American LLC (“NYSE AMER”), or listed or quoted on an exchange or quotation system that is a successor to Nasdaq, the NYSE or the NYSE AMER, and (ii) we are not subject to the reporting requirements of the Exchange Act, but any Series A Preferred Stock is still outstanding.

Upon the occurrence of a Change of Control (as defined below), we may, at our option, redeem the Series A Preferred Stock, in whole or in part within 120 days after the first date on which such Change of Control occurred, for cash, at a redemption price of $25.00 per share, plus any accrued and unpaid dividends up to, but not including, the date of redemption.

A “Change of Control” occurs when, after the original issuance of the Series A Preferred Stock, the following have occurred and are continuing:

the acquisition by any person, including any syndicate or group deemed to be a “person” under Section 13(d)(3) of the Exchange Act, of beneficial ownership, directly or indirectly, through a purchase, merger or other acquisition transaction or series of purchases, mergers or other acquisition transactions of shares of our company entitling that person to exercise more than 50% of the total voting power of all shares of our company entitled to vote generally in elections of directors (except that such person will be deemed to have beneficial ownership of all securities that such person has the right to acquire, whether such right is currently exercisable or is exercisable only upon the occurrence of a subsequent condition); and

following the closing of any transaction referred to in the bullet point above, neither we nor any acquiring or surviving entity (or if, in connection with such transaction shares of our common stock are converted into or exchanged for (in whole or in part) common equity securities of another entity), has a class of common securities (or ADRs representing such securities) listed on Nasdaq, the NYSE or the NYSE AMER, or listed or quoted on an exchange or quotation system that is a successor to Nasdaq, the NYSE or the NYSE AMER.

We refer to redemption following a Delisting Event or Change of Control as a “special optional redemption.” If, prior to the Delisting Event Conversion Date (as defined below) or the Change of Control Conversion Date (as defined below), as applicable, we have provided or provide notice of exercise of any of our redemption rights relating to the Series A Preferred Stock (whether our optional redemption right or our special optional redemption right), the holders of the Series A Preferred Stock will not have the conversion right described below.


Conversion. Upon the occurrence of a Delisting Event or a Change of Control, as applicable, each holder of Series A Preferred Stock will have the right (unless, prior to the Delisting Event Conversion Date or Change of Control Conversion Date, as applicable, we have provided or provide notice of our election to redeem the Series A Preferred Stock) to convert some or all of the Series A Preferred Stock held by such holder on the Delisting Event Conversion Date or Change of Control Conversion Date, as applicable, into a number of shares of our common stock (or equivalent value of alternative consideration) per share of Series A Preferred Stock equal to the lesser of:

the quotient obtained by dividing (1) the sum of the $25.00 per share liquidation preference plus the amount of any accumulated and unpaid dividends up to, but not including, the Delisting Event Conversion Date or Change of Control Conversion Date, as applicable (unless the Delisting Event Conversion Date or Change of Control Conversion Date, as applicable is after a record date for a Series A Preferred Stock dividend payment and prior to the corresponding Series A Preferred Stock dividend payment date, in which case no additional amount for such accumulated and unpaid dividend will be included in this sum) by (2) the Common Stock Price (as defined below); and

1.46071 (i.e., the Share Cap), subject to certain adjustments; and subject, in each case, to certain conditions, including, under specified circumstances, an aggregate cap on the total number of shares of our common stock issuable upon conversion and to provisions for the receipt of alternative consideration.

If, prior to the Delisting Event Conversion Date or Change of Control Conversion Date, as applicable, we have provided or provide a redemption notice, whether pursuant to our special optional redemption right or our optional redemption right, holders of Series A Preferred Stock will not have any right to convert the Series A Preferred Stock, and any Series A Preferred Stock subsequently selected for redemption that has been tendered for conversion will be redeemed on the related date of redemption instead of converted on the Delisting Event Conversion Date or Change of Control Conversion Date, as applicable.


In the event that the conversion would result in the issuance of fractional shares of common stock, we will pay the holder of Series A Preferred Stock cash in lieu of such fractional shares.


Except as provided above in connection with a Delisting Event or Change of Control, shares of the Series A Preferred Stock are not convertible into or exchangeable for any other securities or property.

For purposes of this description, “Change of Control Conversion Date” means a business day fixed by our board of directors that is not fewer than 20 days nor more than 35 days after the date on which we provide notice to the holders of the Series A Preferred Stock of a Change of Control.

For purposes of this description, “Common Stock Price” for any Change of Control will be: (1) if the consideration to be received in the Change of Control by the holders of our common stock is solely cash, the amount of cash consideration per share of common stock; and (2) if the consideration to be received in the Change of Control by holders of our common stock is other than solely cash (x) the average of the closing prices for our common stock on the principal U.S. securities exchange on which our common stock is then traded (or, if no closing sale price is reported, the average of the closing bid and ask prices per share or, if more than one in either case, the average of the average closing bid and the average closing ask prices per share) for the ten consecutive trading days immediately preceding, but not including, the date on which such Change of Control occurred as reported on the principal U.S. securities exchange on which our common stock is then traded, or (y) the average of the last quoted bid prices for our common stock in the over-the-counter market as reported by OTC Markets Group Inc. or similar organization for the ten consecutive trading days immediately preceding, but not including, the date on which such Change of Control occurred, if our common stock is not then listed for trading on a U.S. securities exchange. The “Common Stock Price” for any Delisting Event will be the average of the closing price per share of our common stock on the 10 consecutive trading days immediately preceding, but not including, the effective date of the Delisting Event.

For purposes of this description, “Delisting Event Conversion Date” means a business day fixed by our board of directors that is not fewer than 20 days nor more than 35 days after the date on which we provide notice to the holders of the Series A Preferred Stock of a Delisting Event.


Voting Rights. Holders of Series A Preferred Stock generally will have no voting rights. However, if we do not pay dividends on any outstanding shares of Series A Preferred Stock for six or more quarterly dividend periods (whether or not declared or consecutive), holders of Series A Preferred Stock (voting separately as a class with all other outstanding series of preferred stock upon which like voting rights have been conferred and are exercisable) will be entitled to elect two additional directors to our board of directors to serve until all unpaid dividends have been fully paid or declared and set apart for payment. In addition, certain material and adverse changes to the terms of the Series A Preferred Stock cannot be made without the affirmative vote of holders of at least 66 2/3% of the outstanding shares of Series A Preferred Stock, voting as a separate class. In any matter in which the Series A Preferred Stock may vote, each share of Series A Preferred Stock shall be entitled to one vote.

Anti-takeover Effects of Provisions of our Certificate of Incorporation and By-laws and Delaware Law

Certificate of Incorporation and By-laws Provisions. Our Certificate of Incorporation authorizes our board of directors to issue up to 1,000,000 shares of Preferred Stock without stockholder approval and to set the rights, preferences and other designations, including voting rights, of those shares as the board of directors may determine. In addition, our By-laws require certain procedures to be followed and time periods to be met for any stockholder to propose matters to be considered at annual meetings of stockholders, including nominating directors for election at those meetings. Our By-laws also provide that our board of directors is able to elect a director to fill a vacancy created by the expansion of the board of directors or due to the resignation or departure of an existing board member. Provisions of Delaware law and our Certificate of Incorporation and By-laws could make the acquisition of our company through a tender offer, a proxy contest or other means more difficult and could make the removal of incumbent officers and directors more difficult. We expect these provisions to discourage coercive takeover practices and inadequate takeover bids and to encourage persons seeking to acquire control of our company to first negotiate with our board of directors. We believe that the benefits provided by our ability to negotiate with the proponent of an unfriendly or unsolicited proposal outweigh the disadvantages of discouraging these proposals. We believe the negotiation of an unfriendly or unsolicited proposal could result in an improvement of its terms.

Delaware Law. We are subject to Section 203 of the DGCL, an anti-takeover law. In general, Section 203 prohibits a publicly held Delaware corporation from engaging in a “business combination” with an “interested stockholder” for a period of three years following the date the person became an interested stockholder, unless:

prior to the date of the transaction, the board of directors of the corporation approved either the business combination or the transaction which resulted in the stockholder becoming an interested stockholder;

upon completion of the transaction that resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced, excluding for purposes of determining the number of shares outstanding (a) shares owned by persons who are directors and also officers, and (b) shares owned by employee stock plans in which employee participants do not have the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer; or

on or subsequent to the date of the transaction, the business combination is approved by the board and authorized at an annual or special meeting of stockholders, and not by written consent, by the affirmative vote of at least 66% of the outstanding voting stock which is not owned by the interested stockholder.

Generally, a “business combination” includes a merger, asset or stock sale, or other transaction resulting in a financial benefit to the interested stockholder. An “interested stockholder” is a person who, together with affiliates and associates, beneficially owns, or is an affiliate of the corporation and within three years prior to the determination of interested stockholder status did own, 15% or more of a corporation’s outstanding voting securities. We expect the existence of this provision to have an anti-takeover effect with respect to transactions our board of directors does not approve in advance.

The Series X Preferred Stock. We have designated 5,003 shares of our Preferred Stock as Series X Preferred Stock. The Series X Preferred Stock ranks:


senior to any class or series of our capital stock created specifically ranking by its terms junior to the Series X Preferred Stock;

on parity to our Common Stock;

on parity to any class or series of our capital stock created specifically ranking by its terms on parity with the Series X Preferred Stock; and

junior to any class or series of our capital stock created specifically ranking by its terms senior to the Series X Preferred Stock; 

in each case, as to distributions of assets upon our liquidation, dissolution or winding up whether voluntarily or involuntarily.

Dividends. Holders of Series X Preferred Stock are entitled to receive dividends on shares of Series X Preferred Stock equal (on an as-converted basis) to and in the same form as dividends actually paid on our Common Stock or other junior securities.

Liquidation Preference. In the event of our liquidation, dissolution, or winding up, holders of our Series X Preferred Stock will participate pari passu (on an as-converted basis, without regard to any blocker provisions) with any distribution of proceeds to holders of our Common Stock.

Redemption. We are not obligated to redeem or repurchase any shares of Series X Preferred Stock. Shares of Series X Preferred Stock are not otherwise entitled to any redemption rights or mandatory sinking fund or analogous fund provisions.

Conversion. The Series X Preferred Stock is convertible at the option of the holders thereof at any time after issuance into the number of registered shares of Common Stock determined by dividing the aggregate stated value of the Series X Preferred Stock being converted by the conversion price then in effect. The initial conversion price is $4.03 and is subject to adjustment as described below. No holder may request a conversion of its Series X Preferred Stock to the extent such conversion would result in the holder and its affiliates beneficially owning more than a pre-set conversion blocker threshold, which will initially be set at 19.99% of our Common Stock then outstanding (the “Beneficial Ownership Limitation”). The amount of beneficial ownership of a holder and its affiliates will be determined in accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended, and the rules and regulations of that section.

Conversion Price Adjustment—Stock Dividends and Stock Splits. If we pay a stock dividend or otherwise make a distribution payable in Common Stock on our Common Stock or any Common Stock equivalents, subdivide or combine our outstanding Common Stock, or reclassify our Common Stock in such a way that we issue additional shares of our capital stock, the conversion price will be adjusted by multiplying the then-existing conversion price by a fraction, the numerator of which is the number of shares of Common Stock outstanding immediately before the distribution, dividend, adjustment or recapitalization and the denominator of which is the number of shares of Common Stock outstanding immediately after such action.

Fundamental Transaction. If we effect a “fundamental transaction” (as defined below), then upon any future conversion of the Series X Preferred Stock, the holders will have the right to receive, for each share of Common Stock they would have received upon such conversion, the same kind and amount of securities, cash or property as such holder would have been entitled to receive in the fundamental transaction had it been the holder of Common Stock immediately prior to the fundamental transaction. The term “fundamental transaction” means any of the following:

a merger or consolidation of the Company with or into another entity or any stock sale to, or other business combination in which the Company is not the surviving entity;

the sale of all or substantially all of our assets in one transaction or a series of related transactions;


any completed tender offer or exchange offer involving holders of Common Stock in which more than 50% of the Common Stock is converted or exchanged into other securities, cash or property, regardless of who makes such offer; or

any reclassification of Common Stock or any compulsory share exchange by which our Common Stock is effectively converted into or exchanged for other securities, cash or property (but not a reverse stock split).

If the holders of Common Stock are given a choice as to the securities, cash or property to be received in a fundamental transaction, the holders of Series X Preferred Stock will be given the same choice on conversion of such holders’ shares.

Voting Rights. The Series X Preferred Stock has no voting rights, except to the extent expressly provided in our Certificate of Incorporation or as otherwise required by law. However, so long as 2,502 shares of Series X Preferred Stock are outstanding, we may not take any of the following actions without the affirmative consent of holders of a majority of the outstanding Series X Preferred Stock:

amend our Certificate of Incorporation, By-laws or other charter documents so as to materially, specifically and adversely affect the preferences, rights, or privileges of the Series X Preferred Stock;

issue additional shares of Series X Preferred Stock or increase or decrease the number of authorized shares of Series X Preferred Stock;

sell, assign, monetize, pledge or otherwise divest or encumber our rights under any material license agreement, joint venture or other partnership agreement to which we are a party as of the date of this offering and involving any drug or drug candidate;

issue or commit to issue any other equity securities, with certain exceptions;

issue any equity-based award or compensation to certain of our officers, unless the award has been unanimously approved by our compensation committee at a time when a designee appointed by the Series X Preferred holders is then serving on that committee; or

enter into any agreement or understanding to take any of the actions listed above.

Exhibit 10.56

FORM OF

INDEMNITY AGREEMENT

This Indemnity Agreement (this “Agreement”) dated as of _______________, 20__, is made by and between XOMA Corporation, a Delaware corporation (the “Company”), and ______________________ (“Indemnitee”).

Recitals

A.The Company desires to attract and retain the services of highly qualified individuals as directors, officers, employees and agents.

B.The Company’s bylaws (the “Bylaws”) require that the Company indemnify its officers, directors, and employees to the fullest extent possible, except as prohibited by the Delaware General Corporation Law, as amended (the “Code”), under which the Company is organized and such Bylaws expressly provide that the indemnification provided therein is not exclusive and contemplates that the Company may enter into separate agreements with its directors, officers and other persons to set forth specific indemnification provisions.

C.Indemnitee does not regard the protection currently provided by applicable law, the Company’s governing documents and available insurance as adequate under the present circumstances, and the Company has determined that Indemnitee and other directors, officers, employees and agents of the Company may not be willing to serve or continue to serve in such capacities without additional protection.

D.The Company desires and has requested Indemnitee to serve or continue to serve as a director, officer, employee or agent of the Company, as the case may be, and has proffered this Agreement to Indemnitee as an additional inducement to serve in such capacity.

E.Indemnitee is willing to serve, or to continue to serve, as a director, officer, employee or agent of the Company, as the case may be, if Indemnitee is furnished the indemnity provided for herein by the Company.

Agreement

Now Therefore, in consideration of the mutual covenants and agreements set forth herein, the parties hereto, intending to be legally bound, hereby agree as follows:

1.Definitions.
(a)Agent.  For purposes of this Agreement, the term “agent” of the Company means any person who:  (i) is or was a director, officer, employee or other fiduciary of the Company or a subsidiary of the Company; or (ii) is or was serving at the request or for the

(b)Expenses.  For purposes of this Agreement, the term “expenses” shall be broadly construed and shall include, without limitation, all direct and indirect costs of any type or nature whatsoever (including, without limitation, all attorneys’, witness, or other professional fees and related disbursements, and other out-of-pocket costs of whatever nature), actually and reasonably incurred by Indemnitee in connection with the investigation, defense or appeal of a proceeding or establishing or enforcing a right to indemnification under this Agreement, the Code or otherwise, and amounts paid in settlement by or on behalf of Indemnitee, but shall not include any judgments, fines or penalties actually levied against Indemnitee for such individual’s violations of law. The term “expenses” shall also include reasonable compensation for time spent by Indemnitee for which he is not compensated by the Company or any subsidiary or third party (i) for any period during which Indemnitee is not an agent, in the employment of, or providing services for compensation to, the Company or any subsidiary; and (ii) if the rate of compensation and estimated time involved is approved by the directors of the Company who are not parties to any action with respect to which expenses are incurred, for Indemnitee while an agent of, employed by, or providing services for compensation to, the Company or any subsidiary.
(c)Proceedings.  For purposes of this Agreement, the term “proceeding” shall be broadly construed and shall include, without limitation, any threatened, pending, or completed action, suit, arbitration, alternate dispute resolution mechanism, investigation, inquiry, administrative hearing or any other actual, threatened or completed proceeding, whether brought in the right of the Company or otherwise and whether of a civil, criminal, administrative or investigative nature, and whether formal or informal in any case, in which Indemnitee was, is or will be involved as a party or otherwise by reason of:  (i) the fact that Indemnitee is or was a director or officer of the Company; (ii) the fact that any action taken by Indemnitee or of any action on Indemnitee’s part while acting as director, officer, employee or agent of the Company; or (iii) the fact that Indemnitee is or was serving at the request of the Company as a director, officer, employee or agent of another corporation, partnership, joint venture, trust, employee benefit plan or other enterprise, and in any such case described above, whether or not serving in any such capacity at the time any liability or expense is incurred for which indemnification, reimbursement, or advancement of expenses may be provided under this Agreement.
(d)Subsidiary.  For purposes of this Agreement, the term “subsidiary” means any corporation or limited liability company of which more than 50% of the outstanding voting securities or equity interests are owned, directly or indirectly, by the Company and one or more of its subsidiaries, and any other corporation, limited liability company, partnership, joint venture, trust, employee benefit plan or other enterprise of which Indemnitee is or was serving at the request of the Company as a director, officer, employee, agent or fiduciary.
(e)Independent Counsel.  For purposes of this Agreement, the term “independent counsel” means a law firm, or a partner (or, if applicable, member) of such a law firm, that is experienced in matters of corporation law and neither presently is, nor in the past five (5) years has been, retained to represent: (i) the Company or Indemnitee in any matter material to either such party, or (ii) any other party to the proceeding giving rise to a claim for indemnification

2.

195711470 v2


hereunder.  Notwithstanding the foregoing, the term “independent counsel” shall not include any person who, under the applicable standards of professional conduct then prevailing, would have a conflict of interest in representing either the Company or Indemnitee in an action to determine Indemnitee’s rights under this Agreement.
2.Agreement to Serve.  Indemnitee will serve, or continue to serve, as a director, officer, employee or agent of the Company or any subsidiary, as the case may be, faithfully and to the best of his or her ability, at the will of such corporation (or under separate agreement, if such agreement exists), in the capacity Indemnitee currently serves as an agent of such corporation, so long as Indemnitee is duly appointed or elected and qualified in accordance with the applicable provisions of the bylaws or other applicable charter documents of such corporation, or until such time as Indemnitee tenders his or her resignation in writing or is removed or dismissed; provided, however, that nothing contained in this Agreement is intended as an employment agreement between Indemnitee and the Company or any of its subsidiaries or to create any right to continued employment of Indemnitee with the Company or any of its subsidiaries in any capacity.

The Company acknowledges that it has entered into this Agreement and assumes the obligations imposed on it hereby, in addition to and separate from its obligations to Indemnitee under the Bylaws, to induce Indemnitee to serve, or continue to serve, as a director, officer, employee or agent of the Company, and the Company acknowledges that Indemnitee is relying upon this Agreement in serving as a director, officer, employee or agent of the Company.

3.Indemnification.
(a)Indemnification in Third Party Proceedings.  Subject to Section 10 below, the Company shall indemnify Indemnitee to the fullest extent permitted by the Code, as the same may be amended from time to time (but, only to the extent that such amendment permits Indemnitee to be granted broader indemnification rights than the Code permitted prior to adoption of such amendment), if Indemnitee is a party to or threatened to be made a party to or otherwise involved in any proceeding, for any and all expenses, actually and reasonably incurred by Indemnitee in connection with the investigation, defense, settlement or appeal of such proceeding.
(b)Indemnification in Derivative Actions and Direct Actions by the Company.  Subject to Section 10 below, the Company shall indemnify Indemnitee to the fullest extent permitted by the Code, as the same may be amended from time to time (but, only to the extent that such amendment permits Indemnitee to be granted broader indemnification rights than the Code permitted prior to adoption of such amendment), if Indemnitee is a party to or threatened to be made a party to or otherwise involved in any proceeding by or in the right of the Company to procure a judgment in its favor, against any and all expenses actually and reasonably incurred by Indemnitee in connection with the investigation, defense, settlement, or appeal of such proceedings.
4.Indemnification of Expenses of Successful Party.  Notwithstanding any other provision of this Agreement, to the extent that Indemnitee has been successful on the merits or otherwise in defense of any proceeding or in defense of any claim, issue or matter therein, including the dismissal of any action without prejudice, the Company shall indemnify Indemnitee

3.

195711470 v2


against all expenses actually and reasonably incurred in connection with the investigation, defense or appeal of such proceeding.
5.Partial Indemnification.  If Indemnitee is entitled under any provision of this Agreement to indemnification by the Company for some or a portion of any expenses actually and reasonably incurred by Indemnitee in the investigation, defense, settlement or appeal of a proceeding, but is precluded by applicable law or the specific terms of this Agreement to indemnification for the total amount thereof, the Company shall nevertheless indemnify Indemnitee for the portion thereof to which Indemnitee is entitled.
6.Advancement of Expenses.  To the extent not prohibited by law, the Company shall advance  the expenses incurred by Indemnitee in connection with any proceeding, and such advancement shall be made within twenty (20) days after the receipt by the Company of a statement or statements requesting such advances (which shall include invoices received by Indemnitee in connection with such expenses but, in the case of invoices in connection with legal services, any references to legal work performed or to expenditures made that would cause Indemnitee to waive any privilege accorded by applicable law shall not be included with the invoice) and upon request of the Company, an undertaking to repay the advancement of expenses if and to the extent that it is ultimately determined by a court of competent jurisdiction in a final judgment, not subject to appeal, that Indemnitee is not entitled to be indemnified by the Company.  Advances shall be unsecured, interest free and without regard to Indemnitee’s ability to repay the expenses. Advances shall include any and all expenses actually and reasonably incurred by Indemnitee pursuing an action to enforce Indemnitee’s right to indemnification under this Agreement, or otherwise and this right of advancement, including expenses incurred preparing and forwarding statements to the Company to support the advances claimed.  Indemnitee acknowledges that the execution and delivery of this Agreement shall constitute an undertaking providing that Indemnitee shall, to the fullest extent required by law, repay the advance if and to the extent that it is ultimately determined by a court of competent jurisdiction in a final judgment, not subject to appeal, that Indemnitee is not entitled to be indemnified by the Company.  The right to advances under this Section shall continue until final disposition of any proceeding, including any appeal thereof.  This Section 6 shall not apply to any claim made by Indemnitee for which indemnity is excluded pursuant to Section 10(b).
7.Notice and Other Indemnification Procedures.
(a)Notification of Proceeding.  Indemnitee will notify the Company in writing promptly upon being served with any summons, citation, subpoena, complaint, indictment, information or other document relating to any proceeding or matter which may be subject to indemnification or advancement of expenses covered hereunder.  The failure of Indemnitee to so notify the Company shall not relieve the Company of any obligation which it may have to Indemnitee under this Agreement or otherwise.
(b)Request for Indemnification and Indemnification Payments.  Indemnitee shall notify the Company promptly in writing upon receiving notice of any demand, judgment or other requirement for payment that Indemnitee reasonably believes to be subject to indemnification under the terms of this Agreement, and shall request payment thereof by the Company.  Indemnification payments requested by Indemnitee under Section 3 hereof shall be

4.

195711470 v2


made by the Company no later than sixty (60) days after receipt of the written request of Indemnitee.  Claims for advancement of expenses shall be made under the provisions of Section 6 herein.
(c)Application for Enforcement.  In the event the Company fails to make timely payments as set forth in Sections 6 or 7(b) above, Indemnitee shall have the right to apply to any court of competent jurisdiction for the purpose of enforcing Indemnitee’s right to indemnification or advancement of expenses pursuant to this Agreement.  In such an enforcement hearing or proceeding, the burden of proof shall be on the Company to prove that indemnification or advancement of expenses to Indemnitee is not required under this Agreement or permitted by applicable law.  Any determination by the Company (including its Board of Directors, stockholders or independent counsel) that Indemnitee is not entitled to indemnification hereunder, shall not be a defense by the Company to the action nor create any presumption that Indemnitee is not entitled to indemnification or advancement of expenses hereunder.
(d)Indemnification of Certain Expenses.  The Company shall indemnify Indemnitee against all expenses incurred in connection with any hearing or proceeding under this Section 7 unless the Company prevails in such hearing or proceeding on the merits in all material respects.
8.Assumption of Defense.  In the event the Company shall be requested by Indemnitee to pay the expenses of any proceeding, the Company, if appropriate, shall be entitled to assume the defense of such proceeding, or to participate to the extent permissible in such proceeding, with counsel reasonably acceptable to Indemnitee.  Upon assumption of the defense by the Company and the retention of such counsel by the Company, the Company shall not be liable to Indemnitee under this Agreement for any fees of counsel subsequently incurred by Indemnitee with respect to the same proceeding, provided that Indemnitee shall have the right to employ separate counsel in such proceeding at Indemnitee’s sole cost and expense.  Notwithstanding the foregoing, if Indemnitee’s counsel delivers a written notice to the Company stating that such counsel has reasonably concluded that there may be a conflict of interest between the Company and Indemnitee in the conduct of any such defense or the Company shall not, in fact, have employed counsel or otherwise actively pursued the defense of such proceeding within a reasonable time, then in any such event the fees and expenses of Indemnitee’s counsel to defend such proceeding shall be subject to the indemnification and advancement of expenses provisions of this Agreement.
9.Insurance.  To the extent that the Company maintains an insurance policy or policies providing liability insurance for directors, officers, employees, or agents of the Company or of any subsidiary (“D&O Insurance”), Indemnitee shall be covered by such policy or policies in accordance with its or their terms to the maximum extent of the coverage available for any such director, officer, employee or agent under such policy or policies.  If, at the time of the receipt of a notice of a claim pursuant to the terms hereof, the Company has D&O Insurance in effect, the Company shall give prompt notice of the commencement of such proceeding to the insurers in accordance with the procedures set forth in the respective policies.  The Company shall thereafter take all necessary or desirable action to cause such insurers to pay, on behalf of Indemnitee, all amounts payable as a result of such proceeding in accordance with the terms of such policies.

5.

195711470 v2


10.Exceptions.
(a)Certain Matters.  Any provision herein to the contrary notwithstanding, the Company shall not be obligated pursuant to the terms of this Agreement to indemnify Indemnitee on account of any proceeding with respect to (i) remuneration paid to Indemnitee if it is determined by final judgment or other final adjudication that such remuneration was in violation of law (and, in this respect, both the Company and Indemnitee have been advised that the Securities and Exchange Commission believes that indemnification for liabilities arising under the federal securities laws is against public policy and is, therefore, unenforceable and that claims for indemnification should be submitted to appropriate courts for adjudication, as indicated in Section 10(d) below); (ii) a final judgment rendered against Indemnitee for an accounting, disgorgement or repayment of profits made from the purchase or sale by Indemnitee of securities of the Company against Indemnitee or in connection with a settlement by or on behalf of Indemnitee to the extent it is acknowledged by Indemnitee and the Company that such amount paid in settlement resulted from Indemnitee's conduct from which Indemnitee received monetary personal profit, pursuant to the provisions of Section 16(b) of the Securities Exchange Act of 1934, as amended, or other provisions of any federal, state or local statute or rules and regulations thereunder; (iii) a final judgment or other final adjudication that Indemnitee’s conduct was in bad faith, knowingly fraudulent or deliberately dishonest or constituted willful misconduct (but only to the extent of such specific determination); or (iv) on account of conduct that is established by a final judgment as constituting a breach of Indemnitee’s duty of loyalty to the Company or resulting in any personal profit or advantage to which Indemnitee is not legally entitled.  For purposes of the foregoing sentence, a final judgment or other adjudication may be reached in either the underlying proceeding or action in connection with which indemnification is sought or a separate proceeding or action to establish rights and liabilities under this Agreement.  
(b)Claims Initiated by Indemnitee.  Any provision herein to the contrary notwithstanding, the Company shall not be obligated to indemnify or advance expenses to Indemnitee with respect to proceedings or claims initiated or brought by Indemnitee against the Company or its directors, officers, employees or other agents and not by way of defense, except (i) with respect to proceedings brought to establish or enforce a right to indemnification under this Agreement or under any other agreement, provision in the Bylaws or Certificate of Incorporation or applicable law, or (ii) with respect to any other proceeding initiated by Indemnitee that is either approved by the Board of Directors or Indemnitee’s participation is required by applicable law.  However, indemnification or advancement of expenses may be provided by the Company in specific cases if the Board of Directors determines it to be appropriate.
(c)Unauthorized Settlements.  Any provision herein to the contrary notwithstanding, the Company shall not be obligated pursuant to the terms of this Agreement to indemnify Indemnitee under this Agreement for any amounts paid in settlement of a proceeding effected without the Company’s written consent.  Neither the Company nor Indemnitee shall unreasonably withhold consent to any proposed settlement; provided, however, that the Company may in any event decline to consent to (or to otherwise admit or agree to any liability for indemnification hereunder in respect of) any proposed settlement if the Company is also a party in such proceeding and determines in good faith that such settlement is not in the best interests of the Company and its stockholders.

6.

195711470 v2


(d)Securities Act Liabilities.  Any provision herein to the contrary notwithstanding, the Company shall not be obligated pursuant to the terms of this Agreement to indemnify Indemnitee or otherwise act in violation of any undertaking appearing in and required by the rules and regulations promulgated under the Securities Act of 1933, as amended (the “Act”), or in any registration statement filed with the SEC under the Act.  Indemnitee acknowledges that paragraph (h) of Item 512 of Regulation S-K currently generally requires the Company to undertake in connection with any registration statement filed under the Act to submit the issue of the enforceability of Indemnitee’s rights under this Agreement in connection with any liability under the Act on public policy grounds to a court of appropriate jurisdiction and to be governed by any final adjudication of such issue.  Indemnitee specifically agrees that any such undertaking shall supersede the provisions of this Agreement and to be bound by any such undertaking.
11.Indemnification of Venture Capital Funds.  If (i) Indemnitee is or was affiliated with one or more venture capital funds that has invested in the Company (each a “VC Fund”), (ii) a VC Fund is, or is threatened to be made, a party to or a participant in any proceeding, and (iii) the VC Fund’s involvement in the proceeding is directly related to Indemnitee’s service to the Company as a director of the Company, then the VC Fund shall be entitled to all of the indemnification rights and remedies under this Agreement to the same extent as Indemnitee.
12.Nonexclusivity and Survival of Rights.  The provisions for indemnification and advancement of expenses set forth in this Agreement shall not be deemed exclusive of any other rights which Indemnitee may at any time be entitled under any provision of applicable law, the Company’s Certificate of Incorporation, Bylaws or other agreements, both as to action in Indemnitee’s official capacity and Indemnitee’s action as an agent of the Company, in any court in which a proceeding is brought, and Indemnitee’s rights hereunder shall continue after Indemnitee has ceased acting as an agent of the Company and shall inure to the benefit of the heirs, executors, administrators and assigns of Indemnitee.  The obligations and duties of the Company to Indemnitee under this Agreement shall be binding on the Company and its successors and assigns until terminated in accordance with its terms.  The Company shall require any successor (whether direct or indirect, by purchase, merger, consolidation or otherwise) to all or substantially all of the business or assets of the Company or any of its subsidiaries (as applicable), expressly to assume and agree to perform this Agreement in the same manner and to the same extent that the Company would be required to perform if no such succession had taken place.

No amendment, alteration or repeal of this Agreement or of any provision hereof shall limit or restrict any right of Indemnitee under this Agreement in respect of any action taken or omitted by such Indemnitee in his or her corporate status prior to such amendment, alteration or repeal.  To the extent that a change in the Code, whether by statute or judicial decision, permits greater indemnification or advancement of expenses than would be afforded currently under the Company’s Certificate of Incorporation, Bylaws and this Agreement, it is the intent of the parties hereto that Indemnitee shall enjoy by this Agreement the greater benefits so afforded by such change.  No right or remedy herein conferred is intended to be exclusive of any other right or remedy, and every other right and remedy shall be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise.  The assertion or employment of any right or remedy hereunder, or otherwise, by Indemnitee shall not prevent the concurrent assertion or employment of any other right or remedy by Indemnitee.  

7.

195711470 v2


13.Term.  This Agreement shall continue until and terminate upon the later of: (a) five (5) years after the date that Indemnitee shall have ceased to serve as a director or and/or officer, employee or agent of the Company; or (b) one (1) year after the final termination of any proceeding, including any appeal then pending, in respect to which Indemnitee was granted rights of indemnification or advancement of expenses hereunder.  

No legal action shall be brought and no cause of action shall be asserted by or in the right of the Company against an Indemnitee or an Indemnitee's estate, spouse, heirs, executors or personal or legal representatives after the expiration of five (5) years from the date of accrual of such cause of action, and any claim or cause of action of the Company shall be extinguished and deemed released unless asserted by the timely filing of a legal action within such five-year period; provided, however, that if any shorter period of limitations is otherwise applicable to such cause of action, such shorter period shall govern.

B.XOMA is willing to grant VIVENTIA such a non-exclusive license, on the terms and conditions set forth below.

NOW, THEREFORE, in consideration of the promises and the mutual covenants hereinafter recited, the parties agree as follows:

ARTICLE 1 — DEFINITIONS

In this Agreement, the following terms shall have the meanings set forth in this Article.

1.1Affiliate” means any corporation or other entity which is directly or indirectly controlling, controlled by or under common control with a party hereto. For the purpose of this Agreement, “control” shall mean the direct or indirect ownership of at least fifty percent (50%) of the outstanding shares or other voting rights of the subject entity to elect directors.


1.2BLA” means a Biologics License Application (or, if applicable, a Product License Application), as defined in the U.S. Food, Drug and Cosmetic Act and the regulations promulgated thereunder, and any corresponding U.S. or foreign application, registration or certification.

1.3.Confidential Information” shall mean (i) any proprietary or confidential information or material in tangible form disclosed hereunder that is designated as “Confidential” at the time it is delivered to the receiving party, or (ii) proprietary or confidential information disclosed orally hereunder which is identified as confidential or proprietary when disclosed and such disclosure of confidential information is confirmed in writing within thirty (30) days by the disclosing party.


1.4Field” shall mean the treatment or prophylaxis of a human or animal disease state or condition and shall exclude Phage Display.

1.5Immunoglobulin” means any molecule that has an amino acid sequence by virtue of which it specifically interacts with an antigen and wherein any chains of the molecule contain a functionally operating region of an antibody variable region including, without limitation, any naturally occurring or recombinant form of such a molecule.

1.6IND” shall mean an Investigational New Drug application, as defined in the U.S. Food, Drug and Cosmetic Act and the regulations promulgated thereunder for initiating clinical trials in the United States, or any corresponding foreign application, registration or certification.

1.7Know-How” means unpatented and/ or unpatentable technical information, including ideas, concepts, inventions, discoveries, data, designs, formulas, specifications, procedures for experiments and tests and other protocols, results of experimentation and testing, fermentation and purification techniques, and assay protocols owned by XOMA as of the Effective Date which may be necessary for the practice of the Patent Rights, which XOMA has the right to license, and which have been transmitted to VIVENTIA. Know-How shall not include the Patent Rights. All Know-How shall be Confidential Information of XOMA.

1.8Licensed Product” will mean any product within the scope of a Valid Claim or produced using any method within the scope of a Valid Claim, or which incorporates or is made using any Know-How, provided however, that the term Licensed Product shall not include Phage Display Materials or any Product which is discovered, isolated, characterized or produced by the use of Phage Display.

1.9Licensed Technology” means the Patent Rights and Know-How.

1.10NDA” shall mean a New Drug Application, as defined in the U.S. Food, Drug and Cosmetic Act and the regulations promulgated thereunder, or any corresponding U.S. or foreign application, registration or certification.

1.11Net Sales” shall mean revenues received by VIVENTIA or its Affiliates as follows: the invoice price of Licensed Products sold by VIVENTIA or its marketing partner(s) to third parties, less, to the extent included in such invoice price the total of: (1) ordinary and customary trade discounts actually allowed; (2) credits, rebates and returns (including, but not limited to, wholesaler and retailer returns); (3) freight, postage, insurance and duties paid for and separately identified on the invoice or other documentation maintained in the ordinary course of business, and (4) excise taxes, other consumption taxes, customs duties and compulsory payments to governmental authorities actually paid and separately identified on the invoice or other documentation maintained in the ordinary course of business.

In the case of pharmacy incentive programs, hospital performance incentive program chargebacks and/or similar programs or discounts on “bundles” of products, VIVENTIA may, with notice to XOMA, discount the bona fide list price of a Licensed Product by the average percentage discount of all VIVENTIA products in a particular “bundle,” calculated as follows:

Average percentage discount on a particular “bundle”

=

A

X 100

B

where A equals the total discounted price of a particular “bundle” of products, and B equals the sum of the undiscounted bona fide list prices of each unit of every product in such “bundle.” VIVENTIA shall provide XOMA documentation, reasonably acceptable to XOMA, establishing such average discount with respect to each “bundle.” If a Licensed Product is not sold separately and no bona fide list price exists for such Licensed Product, the parties shall negotiate in good faith an imputed bona fide list price for such Licensed Product.

or created by or arose out of or is related to use of Licensed Materials, and is made or sold under conditions which, if unlicensed, would constitute infringement of the XOMA Patent Rights.

1.17Third Party” means any person or entity other than VIVENTIA or XOMA.

ARTICLE 9 — TERM AND TERMINATION

9.1Term. The term of this Agreement will commence on the Effective Date and remain in full force and effect until the expiration of the last patent within the Patent Rights, or the tenth anniversary of the first commercial sale of a Licensed Product, whichever is later, unless earlier terminated in accordance with this Article 9.

9.2Termination for Cause. Either party may terminate this Agreement in the event the other party has materially breached or defaulted in the performance of any of its obligations hereunder, and such default has continued for sixty (60) days after written notice thereof was provided to the breaching party by the nonbreaching party. The parties hereby agree that a breach of Section 2.5 is considered to be a material breach of this Agreement. Any termination shall become effective at the end of such sixty (60) day period unless the breaching party has cured any such breach or default prior to the expiration of such period. Notwithstanding the above, in the case of a failure to pay any amount due hereunder the period for cure of any such default following notice thereof shall be ten (10) days and, unless payment is made within such period, the termination shall become effective at the end of such period.

9.3Termination for Insolvency. If voluntary or involuntary proceedings by or against a party are instituted in bankruptcy under any insolvency law, or a receiver or custodian is appointed for such party, or proceedings are instituted by or against such party for corporate reorganization or the dissolution of such party, which proceedings, if involuntary, shall not have been dismissed within sixty (60) days after the date of filing, or if such party makes an assignment for the benefit of creditors, or substantially all of the assets of such party are seized or attached and not released within sixty (60) days thereafter, the other party may immediately terminate this Agreement effective upon notice of such termination.

9.4Effect of Termination.

(a)Accrued Rights and Obligations.

It is understood and agreed that monetary damages may not be a sufficient remedy for any breach of this Agreement and that the non-breaching party may be entitled to injunctive relief as a remedy for any such breach. Such remedy shall not be deemed to be the exclusive remedy for any such breach of this Agreement, but shall be in addition to all other remedies available at law or in equity.

(b)Return of Confidential Information. Upon any termination of this Agreement, VIVENTIA and XOMA shall promptly return to the other party all Confidential Information, including without limitation, any Know-How received from the other party (except XOMA may retain copies of any reports or records referred to in Article 4 or 5).



(c)Stock on Hand.

(d)Licenses. All licenses granted hereunder shall terminate upon the termination of this Agreement.

9.5Survival. Sections 9.4 and 9.5, and Articles 4, 6,7, 8 and 10 of this Agreement shall survive the expiration or termination of this Agreement for any reason.

Re:

Non-Exclusive License Agreement, dated as of November 30, 2001 (the “Agreement”), by and between XOMA (US) LLC as assignee from XOMA Ireland Limited (the “Licensor”) and Viventia Bio Inc. as assignee from Viventia Biotech Inc. (the “Company”)

Dear Jim and Bob:

As you are aware, Viventia Bio Inc. is a wholly-owned subsidiary of Sesen Bio, Inc.  Under the terms of the Agreement the Licensor licensed to the Company certain intellectual property rights and the Company is utilizing those rights in connection with the development and commercialization of Licensed Products such as VB4-845, also known as Vicineum, a locally-administered targeted fusion protein.  As you may also be aware, the Company is in the process of seeking partners for the development and commercialization of this Licensed Product outside the United States.  In connection therewith, the Company proposes to memorialize certain understandings and modifications to the Agreement as set forth in this letter agreement (the “Letter Agreement”) to assist the Company in its partnering efforts, which will benefit both the Licensor and the Company.  

1. Section 2.1 of the Agreement shall be deleted in its entirety and replaced with the following:

“2.1

Grant.  Subject to the terms and conditions of this Agreement, XOMA hereby grants to VIVENTIA and its Affiliates a non-exclusive, non-transferable (except as permitted under Section 10.2), worldwide license under the Licensed Technology to make, have made, use, import, offer for sale and sell Licensed Products in the Field and the limited right to grant Third Party sublicenses to make, have made, use, import, offer for sale and sell Licensed Products developed pursuant to the Agreement.  Any such Third Party sublicense will be consistent with the terms and conditions of this Agreement, and VIVENTIA will provide XOMA with a complete copy of any agreement granting a sublicense under this Agreement to make, have

made, use, import, offer for sale and sell Licensed Products for use in the  Field within thirty (30) days of execution of such Third Party sublicense agreement which shall be subject to the confidentiality provisions hereof. VIVENTIA shall (i) cause any such  sublicensee to comply with the terms of this Agreement, including, without limitation, requiring that each sublicensee shall agree to be bound by all of the obligations, terms and conditions that obligate, bind or affect VIVENTIA under this License Agreement to the extent that such obligations, terms and conditions are relevant given the nature of the rights granted by VIVENTIA to any given sublicensee, (ii) remain responsible for the performance and non-performance of any such sublicensee of all of such sublicensee(s)’s obligations provided herein, (iii) VIVENTIA  shall faithfully ascertain, compute, audit and collect all royalties that become payable based upon the activities of each sublicensee hereunder, and provide for and enforce penalties against any sublicensee that conceals sales or willfully takes actions that result in the miscalculation of royalties; (iv) VIVENTIA shall assure itself of the integrity and financial responsibility of each person or entity to whom a sublicense is granted; and (v) VIVENTIA shall agree to establish, police and enforce adequate mechanisms to assure the quality of the Licensed Products produced or sold by its sublicensees.  Any failure by VIVENTIA to fulfill its obligations with respect to the oversight and supervision of its sublicensees shall be, and are hereby deemed to be, a material breach of this Agreement.”

2. The first two sentences of Section 1.11 are deleted in their entirety and replaced with the following language:

“1.11

Net Sales shall mean revenues received by VIVENTIA, its Affiliates and its marketing partners and sublicensees as follows: the invoice price of Licensed Products sold by VIVENTIA, its Affiliates, or its marketing partner(s) or Third Party sublicensees to third parties, less, to the extent included in such invoice price the total of: (1) ordinary and customary trade discounts actually allowed; (2) credits, rebates and returns (including, but not limited to, wholesaler and retailer returns); (3) freight, postage, insurance and duties paid for and separately identified on the invoice or other documentation maintained in the ordinary course of business, and (4) excise taxes, other consumption taxes, customs duties and compulsory payments to governmental authorities actually paid and separately identified on the invoice or other documentation maintained in the ordinary course of business. Net Sales shall also include the fair market value of all other direct or indirect consideration received by VIVENTIA, its Affiliates and its marketing partners and sublicensees in respect of, for or on account of, or otherwise in connection with Licensed Products, whether such consideration is in cash, payment in kind, exchange or another form, but shall not include any payments received for reimbursement of research expenses, including but not limited  to the  conduct  of clinical  trials to the extent that such payments cover the actual cost of such research and development work, or for the purchase of debt or equity of VIVENTIA provided that any such purchase of debt or equity is not a substitute for, or in lieu of, royalty revenue or other revenue generated in respect of the Licensed Products.”    

{J738408 04408292.DOCX}2


3. Notwithstanding anything to the contrary in the Agreement, if the Agreement is terminated by the Licensor pursuant to Section 9.1 or Section 9.2, then upon the request of any Third Party sublicensee of the rights licensed to the Company in accordance with Section 2.1 of the Agreement as modified by this Letter Agreement  (each such sublicensee, a “Sublicensee”), provided that any act or omission of such Sublicensee is not a cause of such termination, the Licensor shall promptly grant a direct license to such Sublicensee to make, have made, use, import, offer for sale and sell Licensed Products in the same Field and same territory as that in the Sublicensee’s agreement with the Company but otherwise on the same terms and conditions as the Agreement as modified by this Letter Agreement.  The foregoing obligations of the Licensor in this section shall survive the termination of the Agreement.

4. All other terms and conditions of the Agreement, as supplemented and modified by this Letter Agreement, shall remain in full force and effect, except to the extent that modification is necessary to reflect the amendments provided for above, and shall also apply to the terms of this Letter Agreement.

5. Capitalized terms used in this Letter Agreement without definition shall have the meaning given to such terms in the Agreement.

If you are in agreement with the terms set forth above, please so indicate in the space provided below for that purpose, whereupon this Letter Agreement shall constitute a binding agreement between the Company and the Licensor.

Very truly yours,

VIVENTIA BIO INC.

AMENDMENT NO. 1 TO COMMON STOCK SALES AGREEMENT

March 10, 2021

H.C. Wainwright & Co., LLC

430 Park Avenue

New York, NY 10022

Ladies and Gentlemen:

XOMA Corporation, a Delaware corporation (the “Company”), together with H.C. Wainwright & Co., Inc. (the “Agent”), are parties to that certain Common Stock Sales Agreement dated December 18, 2018 (the “Original Agreement”). All capitalized terms not defined herein shall have the meanings ascribed to them in the Original Agreement.  The Company and the Agent desire to amend the Original Agreement as set forth in this Amendment No. 1 thereto (this “Amendment) as follows (to be effective as set forth in paragraph 5 below):

1.With respect to issuances of Placement Shares that occur on or after the date this Amendment No. 1 to Common Stock Sales Agreement becomes effective, reference to the “Registration Statement” in the Original Agreement shall refer to the registration statement on Form S-3, as amended, filed with the Securities and Exchange Commission on March 10, 2021 (“New Registration Statement”).

2.The second paragraph of Section 1 of the Original Agreement is hereby deleted and replaced with:

“The Company has filed or shall file, in accordance with the provisions of the Securities Act of 1933, as amended, and the rules and regulations thereunder (the “Securities Act”), with the Securities and Exchange Commission (the “Commission”), a registration statement on Form S-3, including a base prospectus, relating to certain securities, including the Common Stock to be issued from time to time by the Company, and which incorporates by reference documents that the Company has filed or will file in accordance with the provisions of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and the rules and regulations thereunder. The Company has prepared a prospectus included as part of the registration statement, which relates to the Placement Shares to be issued from time to time by the Company pursuant to this Agreement (the “ATM Prospectus”) and shall, if necessary, prepare a prospectus supplement to the base prospectus included as part of the registration statement, which relates to the Placement Shares (a “Prospectus Supplement”). The Company will furnish to HCW, for use by HCW, copies of the prospectus included as part of such registration statement, as supplemented by a Prospectus Supplement, if any, relating to the Placement Shares to be issued from time to time by the Company. The Company may file, if necessary, one or more additional registration statements from time to time that will contain a base prospectus and related prospectus or prospectus supplement, if applicable (which shall be a Prospectus Supplement), with

respect to the Placement Shares. Except where the context otherwise requires, such registration statement(s), and any post-effective amendment thereto, including all documents filed as part thereof or incorporated by reference therein, and including any information contained in a Prospectus (as defined below) subsequently filed with the Commission pursuant to Rule 424(b) under the Securities Act or deemed to be a part of such registration statement(s) pursuant to Rule 430B of the Securities Act, is herein called the “Registration Statement.” The ATM Prospectus together with the base prospectus or base prospectuses, including all documents incorporated or deemed incorporated therein by reference, included in the Registration Statement, as it may be supplemented by a Prospectus Supplement, in the form in which such prospectus or prospectuses and/or Prospectus Supplement have most recently been filed by the Company with the Commission pursuant to Rule 424(b) under the Securities Act, together with any then issued “issuer free writing prospectus(es),” as defined in Rule 433 promulgated under the Securities Act, relating to the Placement Shares that (i) is required to be filed with the Commission by the Company or (ii) is exempt from filing pursuant to Rule 433(d)(5)(1), in each case in the form filed or required to be filed with the Commission or, if not required to be filed, in the form retained in the Company’s records pursuant to Rule 533(g), is herein called the “Prospectus.”

3.All references to “December 18, 2018” set forth in Schedule 1 and Exhibit 7(l) of the Original Agreement are revised to read “December 18, 2018 (as amended by Amendment No. 1, dated March 10, 2021)”.

4.Except as specifically set forth herein, all other provisions of the Original Agreement shall remain in full force and effect.

5.This Amendment No. 1 shall become effective upon the date that the Company’s registration statement on Form S-3 initially filed with the Commission on March 10, 2021 is declared effective under the Securities Act.

6.This Amendment together with the Original Agreement (including all exhibits attached hereto) constitutes the entire agreement and supersedes all other prior and contemporaneous agreements and undertakings, both written and oral, among the parties hereto with regard to the subject matter hereof. Neither this Amendment nor any term hereof may be amended except pursuant to a written instrument executed by the Company and the Agent.  In the event that any one or more of the provisions contained herein, or the application thereof in any circumstance, is held invalid, illegal or unenforceable as written by a court of competent jurisdiction, then such provision shall be given full force and effect to the fullest possible extent that it is valid, legal and enforceable, and the remainder of the terms and provisions herein shall be construed as if such invalid, illegal or unenforceable term or provision was not contained herein, but only to the extent that giving effect to such provision and the remainder of the terms and provisions hereof shall be in accordance with the intent of the parties as reflected in this Amendment. All references in the Original Agreement to the “Agreement” shall mean the Original Agreement as amended by this Amendment; provided, however, that all references to “date of this Agreement” in the Original Agreement shall continue to refer to the date of the Original Agreement.

DM3\7440440.2


7.EACH OF THE COMPANY (ON ITS BEHALF AND, TO THE EXTENT PERMITTED BY APPLICABLE LAW, ON BEHALF OF ITS STOCKHOLDERS AND AFFILIATES) AND THE AGENT HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS AMENDMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

8.THIS AMENDMENT AND ANY CLAIM, CONTROVERSY OR DISPUTE ARISING UNDER OR RELATED TO THIS AMENDMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF, THE STATE OF NEW YORK WITHOUT REGARD TO ITS CHOICE OF LAW PROVISIONS.

9.Each of the Company and the Agent agrees that any legal suit, action or proceeding arising out of or based upon this Amendment or the transactions contemplated hereby (“Related Proceedings”) shall be instituted in (i) the federal courts of the United States of America located in the City and County of New York, Borough of Manhattan or (ii) the courts of the State of New York located in the City and County of New York, Borough of Manhattan (collectively, the “Specified Courts”), and irrevocably submits to the exclusive jurisdiction (except for proceedings instituted in regard to the enforcement of a judgment of any Specified Court, as to which such jurisdiction is non-exclusive) of the Specified Courts in any such suit, action or proceeding. Service of any process, summons, notice or document by mail to a party’s address set forth in Section 14 of the Original Agreement, as amended by this Amendment, shall be effective service of process upon such party for any suit, action or proceeding brought in any Specified Court. Each of the Company and the Agent irrevocably and unconditionally waives any objection to the laying of venue of any suit, action or proceeding in the Specified Courts and irrevocably and unconditionally waives and agrees not to plead or claim in any Specified Court that any such suit, action or proceeding brought in any Specified Court has been brought in an inconvenient forum.

10.This Amendment may be executed in two or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. Delivery of an executed amendment by one party to the other may be made by facsimile transmission or electronic transmission (e.g., PDF).
