   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 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 timing of receipt of those payments. 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 out-license agreements are still being developed, and our licensees’ may require substantial funds to
continue development which may not be available; we may not be successful in entering into out-license agreements for our product candidates; if our therapeutic product
candidates do not receive regulatory approval, our third-party licensees will not be able to manufacture and 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withdrawn or it may be voluntarily taken off the market; we and our licensees are subject to various state and federal healthcare related laws and regulations that may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 are 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.

Item 1.

  Business

 Overview and Strategy

XOMA  Corporation  (“XOMA”),  a  Delaware  corporation,  is  a  biotech  enterprise  with  an  extensive  history  of  discovering  and  developing  innovative  therapeutic
candidates derived from its unique platform of antibody technologies. In March 2017, we transformed our business model to become a royalty aggregator where we focus on
expanding our programs in which we own a right to receive future milestone and royalty payments. These programs and related milestone and royalty interests come from drug
candidates discovered by our licensees and partners from their use of our proprietary antibody discovery platform and from product candidates we discovered from that same
platform,  and  advanced  prior  to  out-licensing.  In  all  cases,  the  licensees  have  assumed  the  responsibility  for  subsequent  development,  regulatory  approval  and
commercialization. When we transitioned to the royalty-aggregator model we significantly reduced corporate infrastructure in order to minimize the cash burn associated with
the period until we expect to experience revenue inflow from these potential milestones and royalties. We expect that a significant portion of our future revenue will be based on
payments we may receive for milestones and royalties related to these programs.

Our strategy has a two-part approach to building value.  The first component of the strategy is to allow our current pipeline of product candidates to advance over time
from  the  investments  made  by  our  licensees.    We  built  this  pipeline  by  out-licensing  our  technology  platform  and  our  drug  candidate  products  to  licensees  or  collaborator
partners  who  assumed  the  responsibilities  of  later  stage  development,  regulatory  approval  and  commercialization.  We  refer  to  these  programs  as  “fully  funded”  since  our
partners pay the development and commercialization costs. As licensees advance these programs, we are eligible for potential milestone and royalty payments. Fundamental to
this component is our focus on maintaining an efficient and low corporate cost structure for the reasons outlined above.  

1

 
 
 
The  second  component  of  our  strategy  is to  expand  our pipeline by acquiring  potential  milestone  and  royalty  revenue  streams  on  additional 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.  In September  of  2018,  we  closed  our  first  acquisition  and  added seven new  programs  to  our  fully-funded  asset pipeline by
acquiring a partial interest position in the rights to potential milestone and royalty payments associated with immuno-oncology antibodies currently being developed by Merck
Sharp & Dohme Corp. (“Merck”) and Incyte Europe Sarl (“Incyte”) under collaboration agreements with Agenus, Inc. and certain affiliates (collectively “Agenus”).

The following charts demonstrate the diversification of our fully-funded asset pipeline across therapeutic areas and development stages.

Selected Programs Underlying Our Core Pipeline

Historically, we have licensed or provided research and development collaboration services to world-class organizations, such as Novartis Pharma AG (“Novartis”) 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-CD40 Antibody

In  September  2015,  we  and  Novartis  Vaccines  and  Diagnostics,  Inc.  (“NVDI”),  further  amended  our  2008  Amended  and  Restated  Research,  Development  and
Commercialization  Agreement,  relating  to  anti-CD40  antibodies.  Under  this  agreement,  NVDI  is  solely  responsible  for  the  development  and  commercialization  of  the
antibodies and products containing the antibodies arising from this program. The parties agreed to reduce the royalty rates that we are eligible to receive on sales of NVDI’s
clinical stage anti-CD40 antibodies (“CFZ533”). These royalties are tiered based on sales levels and now range from a mid-single digit percentage rate to a low double-digit
percentage rate.

Our right to royalty 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.  Novartis is conducting early clinical testing of CFZ533 in several indications.

Novartis – Gevokizumab and IL-1

In August  2017,  we  and  Novartis  entered  into  multiple  license  agreements.  Under  the  first  license  agreement  (the  “XOMA-052  License Agreement”),  we  granted
Novartis an exclusive, worldwide, royalty-bearing license to gevokizumab (“VPM087”) (an early clinical stage product candidate) and related know-how and patents. Under the
terms  of  the  XOMA-052  License  Agreement,  Novartis  will  be  solely  responsible  for  the  development  and  commercialization  of  VPM087  and  products  containing  such
antibody.

2

 
 
 
Under  the  XOMA-052  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 range from a high single digit percentage rate to a low double-digit percentage rate. This program is in early clinical testing.

Under the second license agreement (the “IL-1 Target License Agreement”), we granted Novartis non-exclusive licenses to our 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. We also granted Novartis the right of first negotiation with respect
to certain transactions relating to the licensed intellectual property.  

Under the IL-1 Target License Agreement, we received an upfront cash payment of $10.0 million. In addition, we are eligible to receive low single-digit royalties on

canakinumab sales in cardiovascular indications.

In October 2018, Novartis disclosed that it received a Complete Response Letter (“CRL”) from the Food and Drug Administration (“FDA”) regarding the supplemental
Biologics  License  Application  for  cardiovascular  risk  reduction  related  to  canakinumab.  In  December  2018,  Novartis  withdrew  the  European  marketing  application  for
canakinumab for cardiovascular risk reduction.

Unless  terminated  earlier,  the  XOMA-052  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 XOMA-052 License Agreement on a product-by-product and country-by-country basis or in its entirety on six months’ prior written notice.
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.

Novartis – Anti-TGFβ Antibody

In September 2015, we and Novartis International Pharmaceutical Ltd. (“Novartis International”) entered into a license agreement (the “License Agreement”) under
which  we  granted  Novartis  International  an  exclusive,  worldwide,  royalty-bearing  license  to  our  anti-TGF-β  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  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  range  from  a  mid-single  digit
percentage rate to a low double-digit percentage rate. This program is currently in early clinical testing.

Rezolute

On December 6, 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 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, 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.

3

 
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.  If  Rezolute  exercises  the  option,  we  will  be  eligible  for  an  upfront  option  fee  and  additional  clinical,  regulatory  and  annual  net  sales  milestone
payments to us of up to $237.0 million in the aggregate based on the achievement of pre-specified criteria as well as royalties ranging from a high single digit percentage rate to
a low double-digit percentage rate based on annual net sales. 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. We have the right to terminate the license agreement if Rezolute
challenges the licensed patents.

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 is 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 does not complete a financing that raises at least $20.0 million in
aggregate gross proceeds (“Qualified Financing”) by March 31, 2019 (the “2019 Closing”), it shall 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 is unable to complete a Qualified Financing by March 31, 2020, it will be 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, 2018.

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 are also entitled to receive $0.3 million of reimbursable technology transfer expenses from
Rezolute.  On  January  7,  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  (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 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 future payment date. In accordance with the terms of the license agreement, we received additional
$5.5 million in cash upon the closing of the Qualified Financing.

In addition, the license agreement amendment 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.

Takeda

In November 2006, we entered into a collaboration agreement with Takeda under which we agreed to discover and optimize therapeutic antibodies against multiple

targets selected by Takeda.

Under the terms of this agreement, we may receive additional milestone payments aggregating up to $19.0 million relating to one undisclosed product candidate and
low single-digit royalties on future sales of all 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

4

 
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.

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 patent.

Ology Bioservices

On November 4, 2015, we entered into an asset purchase agreement with Ology Bioservices, Inc. (“Ology Bioservices”) (formerly Nanotherapeutics Inc.) (the “Ology
Bioservices Purchase Agreement”), under which Ology Bioservices agreed to acquire our biodefense business and related assets. Under the terms of this agreement, we are
eligible to receive a 15% royalty on net sales of any future Ology Bioservices products covered by or involving the related patents or know-how. Further details of the Ology
Bioservices Purchase Agreement are provided in the section below, “Sale of Biodefense Assets and Manufacturing Facility.”

Acquisitions

Agenus Royalty Purchase Agreement

On September 20, 2018, we entered into a Royalty Purchase Agreement (the “Royalty Purchase Agreement”) with Agenus. Under the 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, with the exception of an expected near-term milestone associated with the
entry of INCAGN2390 (anti-TIM-3) into the clinical trial. 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 an undisclosed Merck immuno-oncology product currently in clinical development. Pursuant to the
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 Royalty Purchase Agreement, we paid Agenus $15.0 million. We have 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.  

Proprietary Product Candidates

We have a pipeline of unique monoclonal antibodies and technologies that we intend to attempt to license to pharmaceutical and biotechnology companies to further

their clinical development. A summary of these product candidates is provided below:

•

•

•

•

X213 (formerly  LFA  102)  is  a  first-in-class  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.

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.

IL-2 targets  interleukin  2  and  has  long  been  recognized  as  an  effective  therapy  for  metastatic  melanoma  and  renal  cell  carcinoma,  but  it  has  serious  dose-
limiting toxicities that prevent broad clinical use. We have generated novel antibodies that, when given with IL-2, are intended to steer IL-2 to enhance its
positive impact with less toxicity, potentially improving the therapeutic index over standard IL-2 therapy.

PTH1R is an anti-parathyroid receptor pipeline that includes several unique 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.

Technologies Available for Non-Exclusive License

We have a unique 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 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.

Sale of Biodefense Assets and Manufacturing Facility

Ology Bioservices

On  November  4,  2015,  we  entered  the  Ology  Bioservices  Purchase  Agreement  with  Ology  Bioservices,  under  which  Ology  Bioservices  agreed  to  acquire  our
biodefense business and related assets (including certain contracts with the U.S. government), and to assume certain liabilities of XOMA. As part of that transaction, the parties,
subject to the satisfaction of certain conditions, entered into an intellectual property license agreement (the “Ology Bioservices License Agreement”), under which we agreed to
license to Ology Bioservices certain intellectual property rights related to the purchased assets. Under the Ology Bioservices License Agreement, we were eligible for up to $4.5
million of cash payments and 23,008 shares of common stock of Ology Bioservices, based upon Ology Bioservices achieving certain specified future operational objectives. In
addition, we are eligible to receive a 15% royalty on net sales of any future Ology Bioservices products covered by or involving the related patents or know-how. Our right to
royalties continues until the expiration of the last-to-expire licensed patent.

In  February  2017,  we  executed  an  Amendment  and  Restatement  to  both  the  Ology  Bioservices  Purchase  Agreement  and  Ology  Bioservices  License  Agreement
primarily  to  (i)  remove  the  obligation  to  issue  23,008  shares  of  common  stock  of  Ology  Bioservices  under  the  Ology  Bioservices  Purchase Agreement,  and  (ii)  revise  the
payment schedule related to the timing of the $4.5 million cash payments due to us under the Ology Bioservices License Agreement. Of the $4.5 million, $3.0 million was
contingent  upon  Ology  Bioservices  achieving  certain  specified  future  operating  objectives.  In  the  first  quarter  of  2017,  we  were  entitled  to  receive  $1.6  million  under  the
agreement that was received in quarterly payments through September 2018. In the third quarter of 2017, Ology Bioservices achieved the specified operating objectives and we
earned the $3.0 million milestone fee that was received in monthly payments through July 2018. Of the total $4.6 million owed to us, we received $2.4 million during the year
ended December 31, 2018, and $2.2 million during the year ended December 31, 2017, which was recognized as other income in our consolidated statement of operations and
comprehensive (loss) income. No further payments remain under the agreement, but we are still eligible to receive royalties in the future.

Sale of Future Revenue Streams

Royalty Acquisition Agreements

On  December  21,  2016,  we  entered  into  two  Royalty  Interest Acquisition Agreements  (together,  the  “Royalty Acquisition Agreements”)  with  HealthCare  Royalty
Partners II, L.P. (“HCRP”). Under the first Royalty Acquisition Agreement, we sold our right to receive milestone payments and royalties on future sales of products subject to
a license agreement, dated August 18, 2005, between XOMA and Pfizer, Inc. (“Pfizer”) (formerly Wyeth) 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 are met by Pfizer in 2017, 2018 and 2019. The 2017 sales milestone was not achieved. Based on
estimated sales for 2018, the 2018 sales milestone was not achieved. We remain eligible to receive up to $2.0 million if specified net sales milestones are achieved in 2019.
Under the second Royalty Acquisition Agreement entered into in December 2016, we sold all rights to royalties under an Amended and Restated License Agreement dated
October 27, 2006 between XOMA and Shire Plc. (formerly Dyax, Corp.) for a cash payment of $11.5 million.

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. On June 19, 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. On
September  22,  2017,  in  connection  with  the  XOMA-052  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. At  December  31,  2018,  the  outstanding  principal
balance under this note agreement totaled $15.2 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 may borrow advances under the Term Loan from May 7, 2018 (the “Effective Date”) until the earlier of March 31, 2020 or an event
of default. The interest rate will be calculated at a rate equal to the greater of (i) 4.75%, and (ii) 0.25% plus the prime rate as reported from time to time in The Wall Street
Journal.

In connection with the Loan Agreement, we 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 XOMA.

In September 2018, we borrowed $7.5 million under the Loan Agreement in connection with the Agenus royalty purchase agreement.

In March 2019, 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 new 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.

Servier

In  December  2010,  in  connection  with  the  collaboration  agreement  entered  into  with  Servier,  we  executed  a  loan  agreement  with  Servier  (the  “Servier  Loan
Agreement”),  which  provided  for  an  advance  of  up  to  €15.0  million  (or  $19.5  million  at  the  exchange  rate  on  the  date  of  funding).  The  loan  was  secured  by  an  interest  in
XOMA’s intellectual property rights to all gevokizumab (VPM087) indications worldwide, excluding certain rights in the United States and Japan.

On August 25, 2017, NIBR settled the Servier Loan Agreement in cash by paying directly to Servier $14.3 million, which represented the outstanding balance of the
loan based on a euro to dollar exchange rate of 1.1932. The funds that NIBR paid directly to Servier were a portion of the upfront payment due to us under the XOMA-052
License Agreement. As a result of the debt being fully paid, the intellectual property securing the Servier Loan Agreement was released.

7

 
Hercules Loan and Security Agreement

In February 2015, we entered into a Loan and Security Agreement with Hercules Technology Growth Capital, Inc., (the “Hercules Loan Agreement”) under which we

borrowed $20.0 million.

On March 21, 2017, the Hercules Term Loan was paid in full and we were not required to pay the 1% prepayment charge due pursuant to the terms of the loan.

Research and Development

Our  research  and  development  expenses  include  costs  of  personnel,  supplies,  facilities  and  equipment,  consultants,  third-party  costs  and  other  expenses  related  to

preclinical and clinical testing.

Prior  to  2017,  our  research  and  development  activities  can  be  divided  into  those  related  to  our  internal  projects  and  those  related  to  collaborative  and  contract
arrangements, which are reimbursed by our collaborators. In March 2017, we initiated a corporate reorganization to discontinue internal product development and terminated
our clinical programs as of June 30, 2017, both of which significantly reduced our research and development expenses.

Competition

The biotechnology and pharmaceutical industries are subject to continuous and substantial technological change. Some of the drugs our licensees 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 competitors. There can be no assurance that developments by others will not render our, or our licensees’, products or technologies obsolete or uncompetitive.

Additionally, our recently-undertaken 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

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. In addition,
changes in existing regulations could have a material adverse effect on us or our partners.

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  ability  to  obtain  issued  patents,  and  our  partners’  and
licensees’  ability  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. Below is a list of our patents and patent applications related to our programs:

* Novartis-owned patent
**Jointly-owned with Medical University of South Carolina Foundation for Research Development

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 40 fully-funded
programs from which we could potentially receive royalties 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.

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

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 royalties and other intellectual property assets 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, timing and amount of
future  royalty  and  milestone  payments  as  well  as  the  viability  of  the  underlying  technology.  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 the applicable license
agreement(s) covering the potential milestone and royalty streams being acquired. While we generally try to structure our potential receipt of 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 the assets of such counterparty. 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 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.

As part of our royalty aggregator strategy, we will likely purchase future milestone and royalty streams associated with drug products which are in clinical development
and have not yet been commercialized. 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 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  negatively  impact  our
financial condition and results of operation.

12

 
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 the audit.

The royalty and milestone payments we may receive are dependent on our licensees based on their reported 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 the
part of the Company. 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 exercise legal remedies, if available, to enforce our agreements.

The lack of liquidity of our intellectual property acquisitions 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 patents, milestone and royalty rights that have limited secondary resale markets and may be subject to transfer restrictions. The illiquidity of most
of our intellectual property related 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  liquidation  or  otherwise.  In  addition,  if  we  liquidate  all  or  a  portion  of  our  purchased  royalty  stream  assets  quickly  or  relating  to  a
liquidation, we may realize significantly less than the value at which we had previously recorded these assets.

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.

In 2017 we began transforming our business model from a traditional biotech enterprise discovering and developing innovative therapeutics from our own platform of
antibody technologies to a royalty aggregator where we focus on expanding our pipeline of fully-funded programs by acquiring potential milestone and royalty revenue streams
on additional product candidates from third parties and out-licensing our internally developed product candidates.

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 qualify under one of the exemptions or exclusions provided by the ‘40 Act.  If we were to become an “investment company” and be subject to the restrictions of the ‘40 Act,
those restrictions would likely require 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.

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.

With the exception of the year ended December 31, 2017, we have incurred significant operating losses and negative cash flows from operations since our inception.
We had a net loss of $13.3 million for the year ended December 31, 2018 and net income of $14.6 million for the year ended December 31, 2017. As of December 31, 2018,
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 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 by our licensees, 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 licensees’ ability to license product candidates, and the success of our licensees’
development programs, both of which are uncertain. Our success is also dependent on our licensees obtaining regulatory approval to market product candidates which may not
materialize or prove to be successful.

Our new strategy may require us to raise additional funds to acquire royalty assets; 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 royalty assets 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. 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.

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

•

•

•

reduce or eliminate royalty aggregation efforts; or

further reduce our capital or operating expenditures; or

curtail our spending on protecting our intellectual property.

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 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 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
product candidates, or those acquisitions do not perform to our expectations, our financial performance and balance sheet could be adversely affected.

We may not realize the expected benefits of our cost-saving initiatives.

Reducing costs is a key element of our current business strategy. In August 2015, in connection with our efforts to lower operating expenses and preserve capital while
continuing to focus on our product pipeline, we implemented a workforce reduction, which led to the termination of 52 employees during the second half of 2015. In December
2016, we restructured our business to focus our efforts on clinical development, with an initial focus on the X358 clinical program, resulting in a further reduction-in-force in
which  we  terminated  57  employees.  In  early  2017,  we  implemented  a  royalty  aggregator  business  model,  which  resulted  in  the  termination  of  five  additional  employees
effective June 30, 2017.

14

 
 
 
 
If we experience excessive unanticipated inefficiencies or incremental costs in connection with restructuring activities, such as unanticipated inefficiencies caused by
our reduced headcount, we may be unable to meaningfully realize cost savings or capitalize on future opportunities and we may incur expenses in excess of what we anticipate.
Any of these outcomes could prevent us from meeting our strategic objectives and could adversely impact our results of operations and financial condition.

Risks Related to Our Reliance on Third Parties

We  rely  heavily  on  licensee  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 royalty revenues.

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), our product development under these agreements will be delayed or terminated. Disputes or litigation may also arise with our collaborators (with
us and/or with one or more third parties), including those over ownership rights to intellectual property, know-how or technologies developed with our collaborators.

Our licensees rely on third parties to provide services in connection with our product candidate development and manufacturing programs. The inadequate performance by
or loss of any of these service providers could affect our licensees’ 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 we or our licensees have contracted, or cease to continue operations, and we are not able to find a replacement provider quickly or we lose information or
items associated with our product candidates, our 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 contract 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. These audits can result in an adjustment to revenue previously reported, which potentially could be material.

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

Our  licensees  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  and  our  licensees’  product  candidates  on  the  schedule  required  for  our  clinical  trials  or  to  meet  commercial  requirements  may  be  affected.  In
addition, contract manufacturers may not perform their obligations under their agreements with our licensees or may discontinue their business before the time required by us to
successfully produce clinical and commercial supplies of our licensees’ product candidates.

15

 
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 sta ndards. Any difficulties or delays in contractors’ manufacturing and supply of our licensees’ product candidates or any
failure of our licensees’ contractors to maintain compliance with the applicable regulations and standards could increase costs, reduce revenue, 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 licensees’ product
candidates, or cause any of our licensees’ product candidates 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 using them are 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’  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 ability
to commercialize our technologies, products or services.

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 an Investment in Our Common Stock

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

There  can  be  no  assurance  the  market  price  of  our  common  stock  will  not  decline  below  its  present  market  price  or  there  will  be  an  active  trading  market  for  our
common 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 common stock price. We have experienced significant volatility in the price of our
common stock. From January 1, 2018, through March 4, 2019, the share price of our common stock has ranged from a high of $36.86 to a low of $11.02. Additionally, we have
two significant holders of our stock that could affect the liquidity of our stock and have a significant negative impact on our stock price if one or both of the holders were to
quickly sell their ownership positions.

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.

16

 
We may issue additional equity securities and thereby materially and adversely affect the price of our common 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. 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.

We are authorized to issue, without stockholder approval, 1,000,000 shares of preferred stock, of which 5,003 shares of Series X preferred stock and 1,252.772 shares
of Series Y preferred stock were issued and outstanding as of December 31, 2018. 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. The total number of shares of common stock issued upon conversion
of all issued Series X and Series Y convertible preferred stock will be 6,255,772 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 is initially set at 19.99% of our total common stock then issued and outstanding immediately following the conversion of such shares.
If we issue additional equity securities, the price of our common stock may be materially and adversely affected.

In addition, funding from collaboration partners and others has in the past and may in the future involve issuance by us of our common stock. We cannot be certain how

the purchase price of such shares, the relevant market price or premium, if any, will be determined or when such determinations will be made.

Any  issuance  by  us  of  equity  securities,  whether  through  an  underwritten  public  offering,  an  at  the  market  offering,  a  private  placement,  in  connection  with  a

collaboration or otherwise could result in dilution in the value of our issued and outstanding shares, and a decrease in the trading price of our common stock.

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

In order to raise additional funds to support our operations, we may sell additional equity or debt securities, which would result in dilution to our stockholders and may
impose  restrictive  covenants  that  would  adversely  impact  our  business.  The  sale  of  additional  equity  or  convertible  debt  securities  could  result  in  the  issuance  of  additional
shares of our capital stock and dilution to all of our stockholders. 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.

17

 
 
 
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.

We incur significant costs as a result of operating as a public company, which may adversely affect our operating results and financial condition.

As a public company, we incur significant accounting, legal and other expenses, including costs associated with our public company reporting requirements. We also
anticipate that we will continue to incur costs associated with corporate governance requirements, including requirements and rules under SOX and the Dodd-Frank Wall Street
Reform and Consumer Protection Act ("Dodd-Frank") among other rules and regulations implemented by  the  SEC,  as  well  as  listing  requirements  of  Nasdaq.  Furthermore,
these laws and regulations could make it difficult or costly for us to obtain certain types of insurance, including director and officer liability insurance, and we may be forced to
accept reduced policy limits and coverage or incur substantially higher costs to obtain the same or similar coverage. The impact of these requirements could also make it difficult
for us to attract and retain qualified persons to serve on our Board of Directors, our Board Committees or as executive officers.

New laws and regulations as well as changes to existing laws and regulations affecting public companies, including the provisions of SOX and Dodd-Frank and rules
adopted by the SEC and Nasdaq, will likely result in increased costs to us as we respond to their requirements. We continue to invest resources to comply with evolving laws and
regulations, and this investment may result in increased general and administrative expense.

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 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 16, 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, 2018, 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.

18

 
The comprehensive tax reform bill could adversely affect our business and financial condition.

On December 22, 2017, the Tax Cuts and Jobs Act of 2017 was signed into law that significantly revises the Internal Revenue Code of 1986, as amended. The federal
income tax law, among other things, contains significant changes to corporate taxation, including reduction of the corporate tax rate from a top marginal rate of 35% to a flat
rate of 21%, limitation of the tax deduction for interest expense to 30% of adjusted earnings (except for certain small businesses), limitation of the deduction for net operating
losses to 80% of current year taxable income and elimination of net operating loss carrybacks, one time taxation of offshore earnings at reduced rates regardless of whether they
are  repatriated,  immediate  deductions  for  certain  new  investments  instead  of  deductions  for  depreciation  expense  over  time,  and  modifying  or  repealing  many  business
deductions and credits (including reducing the business tax credit for certain clinical testing expenses incurred in the testing of certain drugs for rare diseases or conditions)
which may, as applicable, have an adverse effect on our profitability. Notwithstanding the reduction in the corporate income tax rate, the overall impact of the new federal tax
law is uncertain and our business and financial condition could be adversely affected. In addition, it is uncertain if and to what extent various states will conform to the federal
tax law. The impact of this tax reform on holders of our common stock is also uncertain and could be adverse.

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

We may not be able to successfully identify and acquire and/or in-license other products, product candidates, programs or 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 licenses or 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.

We may not be successful in entering into out-license agreements for our product candidates, which may adversely affect our liquidity and business.

We intend to pursue a strategy to out-license all of our product candidates in order to provide for potential payments, funding and/or royalties on future product sales.
The out-license agreements may be structured to share in the proceeds received by a licensee as a result of further development or commercialization of the product candidates.
We may not be successful in entering into out-licensing agreements with favorable terms as a result of factors, many of which are outside of our control. These factors include:

•

•

•

research and spending priorities of potential licensing partners;

willingness of, and the resources available to, pharmaceutical and biotechnology companies to in-license drug candidates to fill their clinical pipelines; or

our inability to generate proof-of-concept data and to agree with a potential partner on the value of our product candidates, or on the related terms.

19

 
 
 
 
 
If we are unable to enter into out-licensing agreements for our product candidates and realize license, milestone and/or royalty fees when anticipated, it may adversely

affect our liquidity, which in turn may harm our business.

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

Our licensees’ 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 licensees 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.

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

Drug development has inherent risk, and our licensees and 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 we or our licensees 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 licensees’ 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 licensees’ future filings will be delayed;

our licensees’ preclinical studies will be successful;

our licensees 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 licensees will be able to provide necessary data;

results of future clinical trials by our licensees will justify further development; or

our licensees ultimately will achieve regulatory approval for our product candidates.

The  timing  of  the  commencement,  continuation  and  completion  of  clinical  trials  by  our  licensees  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 license our product candidates to others to fund and conduct clinical trials,
we have limited control over how quickly and efficiently such licensees 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 licensees 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  us  to  risks  associated  with  foreign  currency
transactions to make contract payments denominated in the foreign currency where the trial is being conducted.

Products and technologies of other companies may render some or all of our licensees’ product candidates noncompetitive or obsolete.

Developments  by  others  may  render  our  licensees’  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 own 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 licensees. In addition, a significant amount

of research in biotechnology is being carried out in universities and other non-profit

21

 
 
 
 
 
 
 
 
 
 
 
 
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 licensees 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  revenue  derived  from  development  milestones.  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 licensees may halt development of our licensed product candidates.

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

If our third-party licensees 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  us  to  sell  our  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  reimbursement  to  the  patient  from  third-party  payors,  such  as  government  and  private  insurance  plans.  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 business.

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, we or our licensees
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 our product). Consequently,
we do not know if physicians or patients will adopt or use our products 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 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 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.

22

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

We 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;

prevent our competitors from gaining access to our proprietary information and technology; or

permit us 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 partners hold and are in the process of applying for
a number of patents in the United States and abroad to protect our 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 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 intellectual property rights are not protected adequately, our licensees may not be able to commercialize our technologies or products, and our competitors could
commercialize  our  technologies  or  products,  which  could  result  in  a  decrease  in  our  licensees’  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 in the future. Accordingly, there is uncertainty
as to:

•

•

•

whether  any  pending  or  future  patent  applications  held  by  us  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  patents  or  develop  and  obtain  patent  protection  for  technologies,  designs  or  methods  that  are  more
effective than those covered by our patents and patent applications; or

the extent to which our 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, and prevent our licensees from using our technology or product candidates.

If certain patents issued to others are upheld or if certain patent applications filed by others are issued and upheld, our licensees may require licenses from others to
develop and commercialize certain potential products incorporating our technology or we may become involved in litigation to determine the proprietary rights of others. These
licenses, if required, may not be available on acceptable terms, and any such litigation may be costly and may have other adverse effects on our business, such as inhibiting our
licensees’ 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  affect  our  licensees’  ability  to
develop or commercialize our products adversely by giving others a competitive advantage or by undermining our patent position.

23

 
 
 
 
 
 
 
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. 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,  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, thus preventing us, or our licensees, from using these products, processes or services and adversely affecting our revenue.

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

The loss of key personnel, including our Chief Executive Officer or Chief Financial Officer, could delay or prevent achieving our objectives.

Our business efforts could be affected adversely by the loss of one or more key members of our staff, particularly 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.

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

After  a  series  of  restructuring  activities  during  2016  and  2017,  we  had  11  employees  as  of  March  4,  2019.  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 are 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.

Calamities, power shortages or power interruptions at our Emeryville headquarters could disrupt our business and adversely affect our operations.

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

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.

24

 
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.

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. Also, in June 2018, the
State  of  California  enacted  the  California  Consumer  Privacy Act  of  2018,  that  will  go  into  effect  beginning  January  1,  2020,  which  will  also  likely  require  us  to  expend
significant  time  and  resources  to  prepare  for  compliance. 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

25

 
 
 
 
 
 
jurisdictions, such as the California Consumer Privacy Act of 2018, which has been characterized as the first “GDPR-like” privacy statute to be enacted in the United States
because it mirrors a number of the key provisions in the GDPR. We cannot presently determine the impact such laws, regulations and standards will have on our business. In
any event, it is possible that governmental authorities will conclude that our business practices do not comply with current or future statutes, regulations, agency guidance or
case law involving applicable healthcare or privacy laws, including the GDPR, in light of the lack of applicable precedent and regulations.

Shareholder 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 are 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 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.

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 licensees 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 European Medicines Agency (“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.

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 partners 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 licensees’ ability to sell our products, if approved, profitably. Among policy makers and payers 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.

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, reduced product utilization and adversely affect our business and results of operations. Moreover, certain politicians have announced plans to
regulate the prices of pharmaceutical products. We cannot

26

 
 
know what form any such 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 licensees from
being able to generate revenue, attain profitability, or commercialize our current product candidates and those for which we may receive regulatory approval in the future. In
addition,  given  the  uncertainties  related  to  the  Trump Administration’s  stated  goal  of  letting  the Affordable  Care Act  (the  “ACA”)  fail,  we  cannot  be  certain  that  current
provisions of the ACA will continue to cover prescription drug products.

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 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 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 persons from knowingly and willfully soliciting, offering, receiving or providing remuneration, directly or indirectly, in
exchange for or to induce either the referral of an individual, or the furnishing or arranging for a good or service for which payment may be made under a federal healthcare
program,  such  as  the  Medicare  and  Medicaid  programs.  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.  Penalties  for  violations  of  the  federal Anti-Kickback  Statute  include  criminal
penalties and civil sanctions such as fines, penalties, imprisonment and possible exclusion from Medicare, Medicaid and other federal healthcare programs.

The federal False Claims Act prohibits persons 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.  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
individuals, commonly known as “whistleblowers,” 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 a False Claims Act action. When an entity is determined to have violated
the False Claims Act, it may be required to pay up to three times the actual damages sustained by the government, plus civil penalties for each separate false claim. Various
states also have enacted laws modeled after the federal False Claims Act.

The Federal Health Insurance Portability and Accountability Act of 1996 (“HIPAA”) created new federal criminal statutes that prohibit executing a scheme to defraud
any healthcare benefit program and making false statements relating to healthcare matters. The health care fraud statute prohibits knowingly and willfully executing a scheme to
defraud any health care benefit program, including private payors. The statute prohibits knowingly and willfully 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. We take our obligation to maintain our compliance with these various laws and regulations seriously.

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  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, or otherwise restrict payments that may be made to healthcare
providers and other potential referral sources, and to report information related to payments and other transfers of value to physicians and other healthcare providers; as well as
state laws governing the privacy and security of health information in certain circumstances, many of which 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, it is possible that some of our or our licensees’ business activities could be subject to challenge under one or more of such laws.

If we or our licensees are found to be in violation of any of the laws and regulations described above or other applicable state and federal healthcare laws, we may be
subject to penalties, including civil and criminal penalties, damages, fines, exclusion from government healthcare reimbursement programs and the curtailment or restructuring
of our operations, any of which could have a material adverse effect on our business and results of operations.

27

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

We or our licensees 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 licensees 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:

•

•

•

•

•

•

•

•

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.

  Properties

Our corporate headquarters is located in Emeryville, California. We currently lease three buildings that housed our office space and legacy research and development
laboratories.  Our  building  leases  expire  in  the  period  from  2021  to  2023,  and  total  minimum  lease  payments  due  from  January  2019  until  expiration  of  the  leases  is  $14.9
million. We believe that our facilities are adequate to meet our requirements for the near term. We have entered into multiple sublease agreements for portions of our leased
facilities. Under the terms of our sublease agreements, we are entitled to receive $7.9 million in base lease payments over the term of the subleases, which end at the same time
as the original leases. We entered into a sublease agreement in January 2019 and will receive an additional $1.7 million in base lease payments over the term of the sublease,
which ends at the same time as the original lease.

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 4, 2019, there were
207 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. We currently intend to retain any earnings for use in the operations of our business. We, therefore, do not anticipate

paying cash dividends on our common stock in the foreseeable future.

Recent Sales of Unregistered Securities

Except as previously reported in our quarterly reports on Form 10-Q and current reports on Form 8-K filed with the Securities and Exchange Commission (“SEC”),

during the year ended December 31, 2018, there were no unregistered sales of equity securities by us during the year ended December 31, 2018.

 Management’s Discussion and Analysis  of Financial Condition and Results of Operations

Overview

 We have a long history of discovering and developing innovative therapeutics derived from our  unique platform of antibody technologies. Over our extensive history,
we  built  a  pipeline  of  fully-funded  programs  discovered  by  our  licensees  and  partners  from  direct  use  of  our  proprietary  antibody  discovery  platform  and  from  product
candidates  we  discovered  and  advanced  prior  to  licensing  them  to  licensees  who  assumed  the  responsibilities  of  subsequent  development,  regulatory  approval  and
commercialization. Fully-funded programs are those for which our partners pay the development and commercialization costs. As licensees advance these programs, we are
eligible  for  potential  development,  regulatory  and  commercial  milestone  and  royalty  payments. As  part  of  our  royalty  aggregator  business  model,  we  intend  to  continue  to
expand our pipeline of fully-funded programs by acquiring potential milestone and royalty revenue streams on additional product candidates from third parties.

Significant Developments in 2018

Rights Offering

In November 2018, we initiated a rights offering to raise $20.0 million through the distribution of subscription rights to holders of our common stock and Series X
preferred stock. In December 2018, we sold 285,689 shares of our common stock at the subscription price of $13.00 per share and 1,252.772 shares of our Series Y convertible
preferred stock to Biotechnology Value Fund, L.P. (“BVF”) at the subscription price of $13,000.00 per share pursuant to the exercise of subscriptions in the rights offering for
aggregate gross proceeds of $20.0 million.

2018 ATM Agreement

On December 18, 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 will pay HCW a commission of 3% of the
gross proceeds of any shares of common stock sold under the 2018 ATM Agreement. As of December 31, 2018, we have not sold any shares of common stock under the 2018
ATM Agreement.

Agenus

On September 20, 2018, we entered into a Royalty Purchase Agreement with Agenus. Under the 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, with the exception of an expected near-term milestone associated with the entry of INCAGN2390 (anti-TIM-3)
into the clinical trial. 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 an undisclosed Merck immuno-oncology product currently in clinical development. Pursuant to the 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 Royalty Purchase
Agreement, we paid Agenus $15.0 million. We financed $7.5 million of the purchase with a term loan under our Loan and Security Agreement with SVB dated May 7, 2018.  

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 up to $20.0 million. As of December 31, 2018, we borrowed $7.5 million under the Loan Agreement.

31

 
Rezolute

In December 2017, we entered into a license and common stock purchase agreement with Rezolute, which was amended on March 30, 2018. On April 3, 2018, Rezolute
closed a debt financing activity for gross proceeds of $4.0 million, which triggered the Initial Closing defined under the amended common stock purchase agreement between us
and Rezolute. As such, pursuant to the terms of the amended common stock purchase agreement with Rezolute, we received 8,023,758 shares of Rezolute’s common stock and
cash of $0.5 million. In addition, in April 2018, we received from Rezolute the 69,252 shares of common stock and cash of $50,000 in connection with the Interim Financing
Closing  that  occurred  during  the  three  months  ended  March  31,  2018.  Under  the  amended  license  agreement,  we  are  also  entitled  to  receive  $0.3  million  of  reimbursable
technology transfer expenses from Rezolute.

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 revenue recognition 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

Effective  January  1,  2018,  we  adopted  Accounting  Standards  Codification  (“ASC”)  Topic  606, Revenue  from  Contracts  with  Customers ("ASC  606")  using  the
modified retrospective transition method and applied the standard only to contracts that were still active or in place at that date. Also, as permitted, we applied the practical
expedient under ASC 606 which permits us to treat all contract modifications that occurred prior to the adoption in aggregate when determining the performance obligations,
transaction price and its allocation. Except for the license agreement with Rezolute, we did not have any other contracts with customers for which we had not completed our
performance obligations, as of the adoption date January 1, 2018. The license agreement with Rezolute was not considered a contract under ASC 606 as it was not probable that
we  would  collect  substantially  all  of  the  consideration  to  which  we  were  entitled  in  exchange  for  the  goods  or  services  that  were  transferred  to  Rezolute  and  there  was  no
consideration exchanged upon execution of the arrangement or as of January 1, 2018. Thus, we determined that the adoption of ASC 606 did not have a financial impact on our
consolidated financial statements. In addition, the adoption of ASC 606 had no material impact for tax purposes.

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).

32

 
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 change our valuation assumptions used to value stock-based awards granted in future
periods.  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. In 2017, we granted to
certain employees equity awards with performance-based conditions. The actual number of equity awards earned and eligible to vest will be determined based on a specified
level of achievement against a Board-approved budget and operational targets. For awards with performance-based conditions, at the point that it becomes probable that the
performance conditions will be met, we record a cumulative catch-up of the expense from the grant date to the current date, and we then amortize 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.

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 Agenus in September 2018 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. We are not yet able to
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 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 any impairment indicators and changes in expected recoverability of the long-term receivable asset regularly. 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, 2018.

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 2018 was $1.8 million recognized under our license agreement and common stock purchase agreement
with Rezolute, $1.4 million in milestone revenue earned under our license agreement with Janssen Biotech, Inc. and $0.8 million in milestone revenue earned under our license
agreement with Compugen.

The primary components of revenue from contracts with customers in 2017 were $40.2 million of license and collaborative fee revenue recognized in connection with

the license agreements with Novartis AG and $10.0 million in milestone revenue earned under our license agreement with Novartis International Pharmaceutical Ltd.

Revenue recognized under units-of-revenue method

Revenues in 2017 and 2018 include the amortization of unearned revenue from the sale of royalty interests to HealthCare Royalty Partners II, L.P. in December 2016.
Additionally, during the third quarter of 2018, the Shire product underlying the Dyax Corp. license agreement was approved, and we began recognizing revenue under the units-
of-revenue method due to sales of the approved product.

The generation of future revenues related to licenses, milestones, and royalties is dependent on our ability to attract new licensees to our antibody technologies, and the

achievement of milestones or product sales by our existing licensees.

Research and Development Expenses

Research  and  development  (“R&D”)  expenses  primarily  include  salaries  and  related  expenses  for  R&D  personnel  who  evaluate  the  scientific  characteristics  of  our
potential acquisitions of future milestones and royalty streams.  R&D expenses were $1.7 million in 2018, compared with $7.9 million in 2017. The decrease of $6.2 million in
2018, as compared with 2017, was primarily due to the implementation of our royalty-aggregator business model during the first quarter of 2017, which included the cessation
of substantially all development activities. The decrease primarily consisted of $1.9 million in clinical trial costs, $1.4 million in consulting costs, $1.2 million in the allocation
of facilities costs, $0.5 million in stock-based compensation, and a $0.4 million in salaries and related expenses. The decrease in allocation of facilities costs is a result of a
decreased proportion of R&D employees due to our restructuring activities in December 2016 and June 2017.

As  our  business  model  has  changed,  so  has  our  research  and  development  spending  activity.  For  the  year  ended  December  31,  2018,  we  did  not  incur  significant

expenses for internally developed projects.

For the year ended December 31, 2017, X358, for which we incurred the largest amount of expenses, accounted for between 40% and 50% of our total research and
development  expenses.  Each  of  our  remaining  development  programs  accounted  for  less  than  10%  of  our  total  research  and  development  expenses.  Due  to  our  change  in
business model, for the third and fourth quarters of 2017, we did not incur significant expenses for internally developed projects.

We expect our R&D spending in 2019 to remain comparable to 2018 levels.

General and Administrative Expenses

General and administrative (“G&A”) expenses include salaries and related personnel costs, facilities costs and professional fees. In 2018, G&A expenses were $18.6
million  compared  with  $24.3  million  in  2017.  The  decrease  of  $5.7  million  in  2018  as  compared  with  2017  was  primarily  due  to  decreases  of  $2.9  million  in  stock-based
compensation, $2.1 million in consulting services, and $0.5 million in information technology costs, partially offset by an increase of $1.2 million in the allocation of facilities
costs due to a greater proportion of G&A personnel compared to R&D personnel after our restructuring activities.

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 2019 with 2018, consulting expenses may increase in response to an increase in the volume of acquisition targets
evaluated or completed.

Restructuring and Other Charges

In December 2016, we announced a restructuring of our business based on our decision to focus our efforts on clinical development, with an initial focus on the X358
clinical programs. The restructuring included a reduction-in-force in which we terminated 57 employees, which was implemented in December 2016 (the “2016 Restructuring”).
In early 2017, we further revised our strategy to prioritize out-licensing activities and further curtail research and development spending and we eliminated an additional five
employees with an effective termination date of June 30, 2017 (the “2017 Restructuring”). During the year ended December 31, 2017, we recorded charges of $3.4 million
related to severance, other termination benefits and outplacement services for the 2016 Restructuring and 2017 Restructuring activities. There were no such charges during the
year ended December 31, 2018.

During the year ended December 31, 2018, we completely vacated both of our leased facilities in Berkeley, California and met the  criteria  of  a  cease-use  date.  We
recorded a lease-related restructuring liability of $1.4 million as of December 31, 2018, which was adjusted for the remaining balance of deferred rent of $0.7 million. This
resulted  in  us  recording  lease-related  restructuring  charges  of  $1.3  million  for  the  year  ended  December  31,  2018.  In  addition,  in  connection  with  the  sublease  agreement
executed in April 2018, we recognized a loss on the sublease of $0.6 million for year ended December 31, 2018.

The decrease in interest expense compared with 2017 is primarily due to the March 2017 payoff of the Hercules loan and August 2017 payoff of the Servier Loan. On
May 7, 2018, we executed a loan agreement with SVB and on September 21, 2018 we borrowed advances of $7.5 million. We expect our interest expense to increase in 2019
related to the outstanding SVB loan balance and to increase further if we choose to access additional funds.

Loss on Extinguishment of Debt

In March 2017, we paid off our outstanding principal balance, final payment fee and accrued interest totaling $6.5 million under our loan and security agreement with
Hercules, and we were not required to pay the 1% prepayment charge pursuant to the terms of the loan. We recognized a loss on extinguishment of $0.5 million from the payoff
of the Hercules term loan.

2017 related to the disposition of our biodefense business in March 2016 and no further payments are due. During the year ended December 31, 2018, we held  long-term equity
securities which consisted of shares of Rezolute’s common stock. As of December 31, 2018, the fair value of the long-term equity securities decreased and we recognized a loss
of $0.6 million for the year ended December 31, 2018. For the year ended December 31, 2017, the realized foreign exchange loss of $1.6 million was primarily related to re-
measurement of the Servier Loan which was paid in 2017. The gain of $1.2 million on the sale and disposal of equipment for the year ended December 31, 2017 is related to the
sale and disposal of equipment located in one of our leased facilities.

We had $0.1 million income tax benefit for the year ended December 31, 2018 related to our 2017 return to provision adjustment. No other provision was made for
federal  income  tax  since  we  have  incurred  net  operating  losses  during  the  year  ended  December  31,  2018.  Our  $1.7  million  provision  for  income  taxes  for  the  year  ended
December 31, 2017 differs from the amounts computed by multiplying the federal statutory rate by income before taxes primarily due to a reduction in the valuation allowance
and the use of a tax credit carryforward. As of December 31, 2018 and December 31, 2017, we had a total of $4.5 million of net 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.

On December 22, 2017, the U.S. enacted the Tax Cuts and Jobs Act (the “Tax Act”), which significantly changed U.S. tax law. The Tax Act lowered the Company’s

U.S. statutory federal income tax rate from 35% to 21% effective January 1, 2018, while also imposing a deemed repatriation tax on previously deferred foreign income among
other tax changes. In accordance with U.S. Securities and Exchange Commission Staff Accounting Bulletin No. 118, (“SAB 118”), the effects of the Tax Act may be adjusted
within a one-year measurement period from the enactment date.  We have completed our accounting for the income tax effects of the Tax Act during 2018 in accordance with
SAB 118. We have no deferred foreign earnings that would result in Section 965 transition tax. There was also no financial impact on the re-measurement of our deferred tax
assets and liabilities and corresponding valuation allowance as reported on December 31, 2017. Our income tax provision for the year ended December 31, 2018 did not reflect
any adjustment to the previously assessed Tax Act enactment effect.

Net cash used in operating activities for the year ended December 31, 2018 of $12.6 million was primarily due to the $13.3 million net loss incurred.

Net  cash  provided  by  operating  activities  for  the  year  ended  December  31,  2017  was  primarily  due  to  the  $25.7  million  cash  receipts  under  the  license  agreements
executed with Novartis AG in August 2017, which was offset by the $14.3 million non-cash license fee recognized related to the repayment of principal under the Servier Loan
and $6.9 million payments for restructuring related liabilities.

Cash (Used in) Provided by Investing Activities

Net cash used in investing activities for the year ended December 31, 2018 of $15.0 million was due to the purchase of milestone and royalty rights of $15.0 million in

connection with the Agenus Royalty Purchase Agreement executed in September 2018.

Net cash provided by investing activities for the year ended December 31, 2017 of $1.6 million was primarily related to proceeds from the sale of equipment.

Cash Provided by Financing Activities

Net cash provided by financing activities for the year ended December 31, 2018 of $30.0 million was primarily related to the sale of Series Y convertible preferred

stock and common stock issued under the rights offering for total net proceeds of $19.7 million and proceeds received under the SVB loan agreement of $7.5 million.

Net cash provided by financing activities for the year ended December 31, 2017 of $13.3 million was primarily related to the sale of convertible preferred stock and
common stock to BVF for total net proceeds of $24.8 million and the sale of common stock to Novartis for proceeds of $5.0 million. These cash inflows were partially offset by
the payoff of our outstanding loan with Hercules of $17.5 million.

Rights Offering

On November 19, 2018, we initiated a rights offering to raise $20.0 million through the distribution of subscription rights to holders of our common stock and Series X

preferred stock (the “Rights Offering”). In December 2018, we sold a total of 285,689 shares of common stock and 1,252.772 shares of Series Y preferred stock under the
Rights Offering for aggregate gross proceeds of $20.0 million. All Series Y preferred shares were issued to BVF. Total offering costs of $0.3 million were offset against the
proceeds from the sale of common stock and preferred stock.

2018 ATM Agreement

On December 18, 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 will pay HCW a commission of 3% of the
gross proceeds of any shares of common stock sold under the 2018 ATM Agreement. For the year ended December 31, 2018, we have not sold any shares of common stock
under the 2018 ATM Agreement.

SVB Loan Agreement

On May 7, 2018 (the “Effective Date”), we executed the Loan Agreement with SVB. Under the Loan Agreement, upon our request, SVB may make advances (each, a
“Term Loan Advance”) available to us up to $20.0 million (the “Term Loan”). We may borrow advances under the Term Loan until the earlier of March 31, 2019 or an event of
default (the “Draw Period”). Unless an event of default occurs, the period to draw may be extended to March 31, 2020, if we receive $20.0 million in gross cash proceeds from
milestone/licensing payments by March 31, 2019. In the event of a default related to our note agreement with Novartis Pharma AG (“Novartis”), SVB’s obligation to make any
credit  extensions  to  us  under  the  Loan  Agreement  will  immediately  terminate.  As  of  December  31,  2018,  we  have  borrowed  advances  of  $7.5  million  under  the  Loan
Agreement. The interest rate is calculated at a rate equal to the greater of (i) 4.75%, and (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 our loan with Novartis (the
“Loan Maturity Date”). After repayment, no Term Loan Advance (or any portion thereof) may be reborrowed.

37

 
 
The entire principal balance, including a final payment equal to 8.5% of the principal, will be due and payable on the Loan Maturity Date. If we prepay the Term Loan
Advance prior to the Loan Maturity Date, we 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.

We have incurred significant operating losses since our inception and have an accumulated deficit of $1.2 billion at December 31, 2018. As of December 31, 2018, we

had $45.8 million in cash and cash equivalents, which will enable us to maintain our operations for a period of at least 12 months following the filing date of this report.

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 the market demand for
our common stock or debt, which itself is subject to a number of pharmaceutical development and business risks and uncertainties, as well as the uncertainty that we would be
able to raise such additional capital at a price or on terms that are favorable to us.

*        *        *

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  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  $7.5  million  (assuming  one  product  per  contract  meets  all  milestones)  have  not  been  recorded  on  our
consolidated balance sheet as of December 31, 2018. We are unable to 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

We  lease  administrative  facilities  and  office  equipment  under  operating  leases  expiring  on  various  dates  through April  2023.  These  leases  require  us  to  pay  taxes,

insurance, maintenance and minimum lease payments.

We  have  entered  into  multiple  non-cancellable  sublease  agreements  for  portions  of  our  three  leased  facilities.  Under  the  terms  of  our  sublease  agreements,  we  will

receive $7.9 million in base lease payments over the term of the subleases, which end at the same time as the original leases.

Recent Accounting Pronouncements

In February 2016, the Financial Accounting Standards Board (“FASB”) issued ASU 2016-02, Leases (Topic 842). ASU 2016-02 is aimed at making leasing activities
more transparent and comparable, and requires substantially all leases be recognized by lessees on their balance sheet as a right-of-use asset and corresponding lease liability,
including leases currently accounted for as operating leases. Early adoption is permitted and must be adopted using a modified retrospective approach. In July 2018, however,
the FASB issued ASU 2018-11,  Leases (Topic 842): Targeted Improvements, which provides entities with an additional (and optional) transition method which would enable
entities to initially apply the new leases standard at the adoption date and recognize a cumulative-effect adjustment to the opening balance of retained earnings/accumulated
deficit. This optional transition method is in addition to the modified retrospective transition approach included in ASU 2016-02. The new standard will be effective for us on
January 1, 2019 and will be adopted using the optional transition method by recognizing a cumulative effect adjustment to the opening balance of retained earnings as of that
date. The effect of adoption on our financial statements will depend on the leases in effect and our borrowing rates at that time. We will recognize a material right-of-use asset
and corresponding lease liability on the balance sheet upon adoption for our existing leases but we do not expect the adoption to significantly impact our consolidated statement
of operations and comprehensive (loss) income.

38

 
 
In  June  2018,  the  FASB  issued ASU  2018-07, Compensation-  Stock  Compensation  (Topic  718) “Improvements  to  Nonemployee  Share-Based  Payment  Accounting,”
which  expands  the  scope  of  Topic  718  to  include  all  share-based  payment  transactions  for  acquiring  goods  and  services  from  nonemployees.  An  entity  should  apply  the
requirements of Topic 718 to nonemployee awards except for certain exemptions specified in the amendment. ASU 2018-07 is effective for our interim and annual reporting
periods during the year ending December 31, 2019, and all annual and interim reporting periods thereafter. Early adoption is permitted,  but no earlier than an entity’s adoption
date of Topic 606. We elected to early adopt this standard on June 30, 2018. The adoption did not have a material impact on our consolidated financial statements.

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820), 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 will delay adoption of additional disclosures as permitted under the ASU. We do not believe adoption
of the guidance will have a significant 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 only to contracts that are not completed at the date we initially applied ASC 606. We are in the process of accessing the impact
of ASU 2018-18 on our consolidated financial statements.

  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,  2018.  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, 2018, our internal control over financial reporting is effective based on those criteria.

This annual report includes an attestation report of the Company's registered public accounting firm, Deloitte & Touche LLP, regarding the effectiveness of our internal

control over financial reporting as of December 31, 2018.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting during the quarter ended December 31, 2018 that have materially affected, or are reasonably

likely to materially affect, our internal control over financial reporting.

Item 9B.

   Other Information

On March 3, 2019, our Board, in accordance with our Bylaws and the Delaware General Corporation Law, approved an updated form of Indemnity Agreement to be
entered into between the Company and its directors and executive officers.  The Indemnity Agreement provides for indemnification of, and advancement of expenses to, the
Company’s directors and executive officers in specified circumstances.

On March 4, 2019, we and SVB amended the Loan Agreement to extend the Draw Period 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. The warrant was offered
and sold in reliance upon the exemption from registration provided by Section 4(a)(2) under the Securities Act of 1933, as amended (the “Securities Act”).

The foregoing description of the Indemnity Agreement, the amendment to the Loan Agreement and the warrant is not intended to be complete and is qualified in its
entirety by reference to the full text of the Indemnity Agreement, amendment to the Loan Agreement and the warrant, which will be filed as exhibits to our Quarterly Report on
Form 10-Q for the three month period ending March 31, 2019.

 REPORT OF DELOITTE & TOUCHE LLP - 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 sheet of XOMA Corporation and its subsidiaries (the "Company") as of December 31, 2018 and the related

consolidated statements of operations and comprehensive (loss) income, shareholders' equity, and cash flows, for the year ended December 31, 2018, 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, 2018, and the results of its operations and its cash flows for the year ended December 31, 2018, in conformity with accounting principles generally accepted in
the United States of America.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control

over financial reporting as of December 31, 2018, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring
Organizations of the Treadway Commission and our report dated March 7, 2019, expressed an unqualified opinion on the Company's internal control over financial reporting.

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 audit. We are a public accounting firm registered with the 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 audit 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 audit 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 audit 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 audit provides a reasonable basis for our opinion.

REPORT OF DELOITTE & TOUCHE LLP - INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Stockholders and the Board of Directors of XOMA Corporation

Opinion on Internal Control over Financial Reporting

We have audited the internal control over financial reporting of XOMA Corporation and its subsidiaries (the “Company”) as of December 31, 2018, based on criteria
established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion,
the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2018, based on criteria established in Internal Control —
Integrated Framework (2013) issued by COSO.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated financial

statements as of and for the year ended December 31, 2018, of the Company and our report dated March 7, 2019, expressed an unqualified opinion on those financial
statements.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal

control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion
on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the 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 audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance

about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over
financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk,
and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the

preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting
includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the
assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally
accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the
company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have
a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness

to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures
may deteriorate.

 REPORT OF ERNST & YOUNG LLP - 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 sheet of XOMA Corporation as of December 31, 2017, the related consolidated statements of operations and
comprehensive income, stockholders’ equity, and cash flows for the year ended December 31, 2017 and the related notes (collectively referred to as the “consolidated financial
statements”).   In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2017, and the
results of its operations and its cash flows for the year ended December 31, 2017, in conformity with U.S. generally accepted accounting principles.

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 audit. 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 audit 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. The Company is not required to have, nor were we engaged to perform,
an audit of its internal control over financial reporting. As part of our audit we are required to obtain an understanding of internal control over financial reporting but not for the
purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion.

Our audit 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 audit provides a reasonable basis for our opinion.

  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Description of Business

XOMA  Corporation  (referred  to  as  “XOMA”  or  the  “Company”),  a  Delaware  corporation,  has  a  long  history  of  discovering  and  developing  innovative  therapeutic
candidates  derived  from  its  unique  platform  of  antibody  technologies.  Over  the  Company’s  extensive  history,  it  built  a  pipeline  of  fully-funded  programs  discovered  by  its
licensees and partners from direct use of the Company’s proprietary antibody discovery platform and from product candidates it discovered and advanced prior to licensing
them  to  licensees  who  assumed  the  responsibilities  of  subsequent  development,  regulatory  approval  and  commercialization.  Fully-funded  programs  are  those  for  which  the
Company’s  partners  pay  the  development  and  commercialization  costs. As  licensees  advance  these  programs,  the  Company  is  eligible  for  potential  milestone  and  royalty
payments. As  part  of  the  Company’s  royalty  aggregator  business  model,  the  Company  will  continue  to  expand  its  pipeline  of  fully-funded  programs  by  acquiring  potential
milestone and royalty revenue streams on additional product candidates.     

2. Basis of Presentation and Significant Accounting Policies

Principles of Consolidation

The  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.

Liquidity and Financial Condition

With the exception of the year ended December 31, 2017, the Company has incurred significant operating losses and negative cash flows from operations since its
inception. As of December 31, 2018, the Company had cash and cash equivalents of $45.8 million. Based on the Company’s current cash and cash equivalents balance and its
ability to control discretionary spending, such as royalty acquisitions, the Company has evaluated and concluded there are no conditions or events, considered in the aggregate,
that raise substantial doubt about its ability to continue as a going concern for a period of one year following the date that these financial statements are issued.

Reclassification

Certain immaterial prior year amounts have been reclassified to conform to the current year presentation.

Use of Estimates

The preparation of financial statements in conformity with generally accepted accounting principles in the United States (“U.S. GAAP”) 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,  long-term  equity  securities,  debt  amendments,  long-lived  assets,  restructuring  liabilities,  legal
contingencies, income taxes 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. These audits
can result in an adjustment to revenue previously reported which potentially could be material. 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.

Revenue Recognition

Effective January 1, 2018, the Company adopted Accounting Standards Codification (“ASC”) Topic 606, Revenue from Contracts with Customers ("ASC 606") using
the modified retrospective transition method and applied the standard only to contracts that were still active or in place at that date. Also, as permitted, the Company applied the
practical  expedient  under ASC  606  which  permits  the  Company  to  treat  all  contract  modifications  that  occurred  prior  to  the  adoption  in  aggregate  when  determining  the
performance  obligations,  transaction  price  and  its  allocation.  Except  for  the  Company’s  license  agreement  with  Rezolute,  Inc.  (formerly AntriaBio,  Inc.)  (“Rezolute”),  the
Company did not have any other contracts with customers for which the Company had not completed its performance obligations as of the adoption date January 1, 2018. The
license agreement with Rezolute was not considered a contract under ASC 606 as it was not probable that the Company would collect substantially all of the consideration to
which it will be entitled in exchange for the goods or services that were transferred to Rezolute and there was no consideration exchanged upon execution of the arrangement or
as  of  January  1,  2018  (see  Note  4).  Thus,  the  Company  determined  that  the  adoption  of ASC  606  did  not  have  a  financial  impact  on  the  Company's  consolidated  financial
statements. In addition, the adoption of ASC 606 has no material impact for tax purposes. This standard applies to all contracts with customers, except for contracts that are
within the scope of other standards, such as leases, insurance, collaboration arrangements and financial instruments.  Under ASC 606, 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.

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  expects  to  use  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

F-11

 
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 over the vesting period of the award on a straight-line basis. 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.

F-12

 
Restructuring and Impairment Charges

Restructuring costs are primarily comprised of severance costs related to workforce reductions, contract termination costs, lease-related liability and asset impairments.
The Company recognizes restructuring charges when the liability has been incurred, except for employee termination benefits that are incurred over time. Generally, employee
termination benefits (i.e., severance costs) are accrued at the date management has committed to a plan of termination and employees have been notified of their termination
dates and expected severance payments. Key assumptions in determining the restructuring costs include the terms and payments that may be negotiated to terminate certain
contractual obligations and the timing of employees leaving the Company. Other costs, including contract termination costs, are recorded when the arrangement is terminated.
Asset impairment charges have been, and will be, recognized when management has concluded that the assets have been impaired.

For lease-related liability, the Company recognizes the present value of facility lease-related obligations, net of estimated sublease income and other costs, when the
Company has future payments with no future economic benefit. During the year ended December 31, 2018, the Company recorded accretion expense to increase the liability to
an amount equal to the estimated future cash payments necessary to exit the leases. This requires judgment and management estimation to determine the expected time frame for
securing a subtenant, the amount of sublease income to be received and the appropriate discount rate to calculate the present value of the future cash flows. Should actual lease
costs differ from estimates, the Company may be required to adjust the restructuring charge which will impact operating expenses in the period any adjustment is recorded.

Cash and Cash Equivalents

The Company considers all highly liquid debt instruments with maturities of three months or less at the time the Company acquires them and that can be liquidated

without prior notice or penalty to be cash equivalents.

Equity Securities

Effective  January  1,  2018,  the  Company  adopted Accounting  Standards  Update  (“ASU”)  2016-01, Recognition  and  Measurement  of  Financial  Assets  and  Financial
Liabilities. The amendment requires equity investments (except those accounted for under the equity method, those that result in consolidation of the investee and certain other
investments) to be measured at fair value with any changes in fair value recognized in net (loss) income. For equity investments that do not have readily determinable fair values
and do not qualify for the existing practical expedient in ASC 820,  Fair Value Measurements, to estimate fair value using the net asset value per share of the investment, the
Company may choose to measure those investments at cost, less any impairment, plus or minus changes resulting from observable price changes in orderly transactions for the
identical  or  a  similar  investment  of  the  same  issuer.  In  February  2018,  the  Financial Accounting  Standards  Board  (“FASB”)  also  issued ASU  2018-03,  Recognition  and
Measurement of Financial Assets and Financial Liabilities  (ASU  2018-03),  which  made  improvements  to  address  certain  aspects  of  recognition,  measurement,  presentation
and disclosure of financial instruments. ASU 2018-03 is effective for fiscal years beginning after December 15, 2017, and interim periods beginning after June 15, 2018, but
may be adopted concurrently with ASU 2016-01.  As permitted, the Company adopted ASU 2016-01 and ASU 2018-03 concurrently on January 1, 2018. The adoption had no
impact on the consolidated financial statements as the Company did not have any equity investments that existed as of the adoption date.

Subsequent  to  the  adoption  date,  the  Company  received  shares  of  common  stock  from  Rezolute  (Note  4).  Equity  investments  in  Rezolute  are  classified  in  the
consolidated balance sheets as long-term equity securities. The equity securities are measured at fair value, with changes in fair value recorded in other income (expense), net
line  item  of  the  consolidated  statement  of  operations  and  comprehensive  (loss)  income  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) income in the period of sale.

Property and Equipment

Property and equipment is stated at cost less depreciation. Equipment depreciation is calculated using the straight-line method over the estimated useful lives of the
assets (three years). Leasehold improvements were depreciated using the straight-line method over the shorter of the lease terms or the useful lives. Amortization expense for
assets  acquired  through  capital  leases  was  included  in  depreciation  expense  in  the  consolidated  statements  of  operations  and  comprehensive  (loss)  income.  Upon  the  sale,
retirement or disposal of assets, the cost and related accumulated depreciation and amortization are removed from the consolidated balance sheets, and the resulting gain or loss,
if any, is reflected in other income (expense), net in the consolidated statements of operations and comprehensive (loss) income. Repairs and maintenance costs are charged to
expense as incurred.

F-13

 
The  carrying  value  of the  property  and  equipment  is  reviewed  for  impairment  whenever  events  or  changes  in  circumstances  indicate  that  the  asset  may  not  be
recoverable. An impairment loss would be recognized when estimated future cash flows expected to result from the use of the asset and its eventual disposition is less than its
carrying  amount.  During the  year  ended  December  31, 2018,  the  Company  recognized n o impairment  charges.  During  the  year  ended  December  31,  2017,  the  Company
recognized impairment charges of $0.2 million recorded in other income, net line in the consolidated statements of operations and comprehensive income.

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, and royalties on sales of products
currently in clinical development. The Company acquired such rights from Agenus, Inc., and certain affiliates (collectively, “Agenus”), in September 2018 and recorded the
amount paid for these rights as long-term royalty receivables (refer to Note 5). The Company has accounted for the purchased rights as a financial asset in accordance with ASC
310, Receivables.

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 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 any impairment indicators and changes in expected recoverability of the long-term royalty receivable asset regularly. 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 cash flows. No impairment was recorded as of December 31, 2018.

Warrants

The Company has issued warrants to purchase shares of its common stock in connection with financing activities. The Company classifies these warrants as equity and
are recorded at fair value as of the date of issuance on the Company’s consolidated balance sheet and no further adjustments to their valuation are made. The fair value of the
outstanding warrants was estimated using the Black-Scholes Model. The Black-Scholes Model required inputs such as the expected term of the warrants, expected volatility and
risk-free interest rate. These inputs were subjective and required significant analysis and judgment to develop. For the estimate of the expected term, the Company used the full
remaining contractual term of the warrant. The Company determined the expected volatility assumption in the Black-Scholes Model based on historical stock price volatility
observed on the Company’s underlying stock.

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.

Net (Loss) Income per Share Available to Common Stockholders

Basic net (loss) income per share available to common stockholders is based on the weighted average number of shares of common stock outstanding during the period.
Net  (loss)  income  available  to  common  stockholders  consists  of  net  (loss)  income,  as  adjusted  for  any  convertible  preferred  stock  deemed  dividends  related  to  beneficial
conversion features on this instrument at issuance. During periods of income, the Company allocates participating securities a proportional share of net income, after deduction
of any deemed dividends on preferred stock, determined by dividing total weighted average participating securities by the sum of the total weighted average number of common
stock and participating securities (the “two-class method”). The Company’s convertible preferred stock participates in any dividends declared by the Company on its common
stock  and  are  therefore  considered  to  be  participating  securities.  For  the  year  ended  December  31,  2017,  the  convertible  preferred  stock  had  a  deemed  dividend  which
represented the accretion of a beneficial conversion feature. As such, the net income for the year ended December 31, 2017 was adjusted for the convertible preferred stock
deemed dividend related to the beneficial conversion feature on these shares at issuance.

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.
Diluted net (loss) income per share available to common stockholders is based on the weighted average number of shares outstanding during the period, adjusted to include the
assumed conversion of preferred stock, and the exercise of certain stock options, RSUs, and warrants for common stock. The calculation of diluted (loss) income per share
available  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
outstanding options, RSUs or warrants and the presumed exercise of such securities are dilutive to earnings (loss) per share available to common stockholders for the period.
Adjustments to the denominator are required to reflect the related dilutive shares.

Comprehensive (Loss) Income

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

Recent Accounting Pronouncements

In  February  2016,  the  FASB  issued ASU  2016-02, Leases  (Topic  842). ASU  2016-02  is  aimed  at  making  leasing  activities  more  transparent  and  comparable  and
requires substantially all leases be recognized by lessees on their balance sheet as a right-of-use asset and corresponding lease liability, including leases currently accounted for
as operating leases. Early adoption is permitted and must be adopted using a modified retrospective approach. In July 2018, however, the FASB issued ASU 2018-11,  Leases
(Topic 842): Targeted Improvements, which provides entities with an additional (and optional) transition method which would enable entities to initially apply the new leases
standard at the adoption date and recognize a cumulative-effect adjustment to the opening balance of retained earnings/accumulated deficit. This optional transition method is in
addition to the modified retrospective transition approach included in ASU 2016-02. The new standard will be effective for the Company on January 1, 2019 and will be adopted
using the optional transition method by recognizing a cumulative effect adjustment to the opening balance of retained earnings as of that date. The effect of adoption on the
Company’s financial statements will depend on the leases in effect and the Company’s borrowing rates at that time. The Company will recognize a material right-of-use asset
and corresponding lease liability on the balance sheet upon adoption for its existing leases but does not expect the adoption to significantly impact its consolidated statement of
operations and comprehensive (loss) income.

In  June  2018,  the  FASB  issued ASU  2018-07, Compensation-  Stock  Compensation  (Topic  718)  “Improvements  to  Nonemployee  Share-Based  Payment  Accounting,”
which  expands  the  scope  of  Topic  718  to  include  all  share-based  payment  transactions  for  acquiring  goods  and  services  from  nonemployees. An  entity  should  apply  the
requirements of Topic 718 to nonemployee awards except for certain exemptions specified in the amendment. ASU 2018-07 is effective for the Company’s interim and annual
reporting periods during the year ending December 31, 2019, and all annual and interim reporting periods thereafter. Early adoption is permitted, but no earlier than an entity’s
adoption  date  of  Topic  606.  The  Company  elected  to  early  adopt  this  standard  on  June  30,  2018.  The  adoption  did  not  have  a  material  impact  on  its  consolidated  financial
statements.

F-15

 
In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820), 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 will delay adoption of additional disclosures as permitted under the ASU.
The Company does not believe adoption of the guidance will have a significant impact on its 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 is in the process of accessing the impact of ASU 2018-18 on its consolidated financial statements.

On August 24, 2017, the Company and Novartis Pharma AG (“Novartis”) entered into a license agreement (the “XOMA-052 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 (the “Antibody”) and related know-how and patents (altogether, the “XOMA IP”). Under the terms of the XOMA-052 License Agreement, Novartis will be solely
responsible for the development and commercialization of the Antibody and products containing the Antibody.

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  XOMA-052  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 XOMA-052 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  XOMA-052  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 XOMA-052 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. The XOMA-052 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 VPM087antibody, 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,  2018. 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,  2018  and  December  31,  2017,  there  are  no  contract  assets  or  contract  liabilities  related  to  this  arrangement.  In  addition,  the  Company  did  not

recognize any revenue related to this arrangement during the year ended December 31, 2018. None of the costs to obtain or fulfill the contract were capitalized.

Novartis International – Anti-TGFβ Antibody

On  September  30,  2015,  the  Company  and  Novartis  International  Pharmaceutical  Ltd.  (“Novartis  International”)  entered  into  a  license  agreement  (the  “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  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 License Agreement will remain in
effect, on a country-by-country and product-by-product basis, until Novartis International’s royalty obligations end. The License Agreement contains customary termination
rights relating to material breach by either party. Novartis International also has a unilateral right to terminate the 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 are multiple promised goods and services under the 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 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. As  of
December 31, 2018, the Company is eligible to receive up to a total of $470.0 million in development, regulatory and commercial milestones.

The  Company  concluded  that  the  development  and  regulatory  milestone  payments  are  solely  dependent  on  Novartis’  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  as  of  December  31,  2018.  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.

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 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.

As of December 31, 2018 and December 31, 2017, there are no contract assets or contract liabilities related to this arrangement. None of the costs to obtain or fulfill the

contract were capitalized.

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”)  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 has 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,
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.

Pursuant  to  the  license  agreement  and  common  stock  purchase  agreement,  the  Company  is  eligible  to  receive  $6.0  million  in  cash  and  $12.0  million  of  Rezolute’s
common stock contingent on the completion of Rezolute’s financing activities. Further, in the event that Rezolute does not complete a financing that raises at least $20.0 million
in aggregate gross proceeds (“Qualified Financing”) by March 31, 2019 (the “2019 Closing”), the Company will receive an additional number of shares of Rezolute’s common
stock equal to $7.0 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 is unable to complete a Qualified Financing by March 31, 2020, the Company is eligible to receive $15.0
million  in  cash  in  order  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 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.  

In addition, under the terms of the license agreement, the Company is eligible to receive a low single digit royalty on sales of Rezolute’s other 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, 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.

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.

On March 30, 2018, the Company and Rezolute amended the license agreement and common stock purchase agreement. The license agreement was amended to add
terms  specifying  the  financial  responsibility  for  certain  tasks  related  to  the  technology  transfer  of  RZ358  license.  The  common  stock  purchase  agreement  was  amended  as
follows: (1) adjusted the total shares due upon the Initial Closing (as defined in the common stock purchase agreement) from $5.0 million in value to 7,000,000 shares; (2)
increased the shares due upon a Qualified Financing from $7.0 million in value to $8.5 million in value; and (3) increased the shares due upon the 2019 Closing from $7.0
million in value to $8.5 million in value. All other terms of the license agreement and common stock purchase agreement remain unchanged.

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 will be based on the timing of those activities.

Upon execution of the arrangement, the Company determined that it is not probable that the Company will collect substantially all of the consideration to which it will
be entitled in exchange for the goods or services that will be transferred to Rezolute. Therefore, the Company determined no contract with a customer existed upon adoption of
ASC 606 on January 1, 2018.

During the three months ended March 31, 2018, Rezolute completed an Interim Financing Closing as defined in the common stock purchase agreement resulting in
consideration due to XOMA consisting of 69,252 shares of Rezolute’s common stock and cash of $50,000. In addition, 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  the  achievement  of  the  Interim  Financing  Closing  and  related
consideration as well as the amendment in March 2018 were not substantive to overcome the collectability criterion required to establish a contract under ASC 606. Thus, there
was no contract as of March 31, 2018 and no revenue was recognized during the three months ended March 31, 2018 under the arrangement.  

On April 3, 2018, Rezolute closed a debt financing activity for gross proceeds of $4.0 million, which triggered the Initial Closing defined under the amended common
stock purchase agreement between the Company and Rezolute. As such, pursuant to the terms of the amended common stock purchase agreement with Rezolute, the Company
received 8,023,758 shares of Rezolute’s common stock and cash of $0.5 million. The cash and share consideration in connection with the Interim Financing Closing during the
three months ended March 31, 2018 and Initial Closing as noted above were received in April 2018. Under the amended 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 represents substantially
all consideration for the delivered license and technology to Rezolute. Therefore, the Company determined that a contract exists between Rezolute and XOMA under ASC 606
on April 3, 2018.

The amended license agreement and amended 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 are 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 is 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  is  not  a
performance obligation. The option fee will be recognized as revenue when, and if, Rezolute exercises its option because the Company has no further performance obligations at
that point.

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 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 other income
(expense), net line item of the consolidated statement of operations and comprehensive (loss) income.

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  December  31,  2018. 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.

As of December 31, 2018, the Company has a receivable from Rezolute related to the reimbursable technology transfer expenses of $0.3 million included in trade and
other receivables on the consolidated balance sheet. As of December 31, 2018, there was no contract liability related to this arrangement. As of December 31, 2017, there were
no contract assets or contract liability related to this arrangement. None of the costs to obtain or fulfill the contract were capitalized.

NIAID

Prior to the sale of the Company’s biodefense business discussed in Note 7, 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  is  remote.  The  Company  classified  $0.8  million  as  contract  liabilities  on  the
consolidated balance sheets as of December 31, 2018 and December 31, 2017.

Sale of Future Revenue Streams

On December 21, 2016, the Company entered into two Royalty Interest Acquisition Agreements (together, the “Acquisition Agreements”) with HCRP. Under the first
Acquisition 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 are met in 2017, 2018 and 2019. The 2017 sales milestone was not achieved. Based on estimated
sales  for  2018,  the  2018  sales  milestone  was  not  achieved.  The  Company  remains  eligible  to  receive  up  to  $2.0  million  if  specified  net  sales  milestones  are  achieved  in
2019. Under the second Acquisition Agreement entered into in December 2016, the Company sold all rights to 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
Acquisition 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 $0.2 million and $0.3 million as revenue under units-of-revenue method under these arrangements during the years ended December 31, 2018
and  December  31,  2017,  respectively. As  of  December  31,  2018,  the  current  and  non-current  portion  of  the  remaining  unearned  revenue  recognized  under  units-of-revenue
method was $0.5 million and $17.0 million, respectively. As of December 31, 2017, the Company classified $0.6 million and $17.1 million as current and non-current unearned
revenue recognized under units-of-revenue method, respectively.

5. Agenus Royalty Purchase Agreement

On  September  20,  2018,  the  Company  entered  into  a  Royalty  Purchase Agreement  (the  “Royalty  Purchase Agreement”)  with Agenus.  Under  the  Royalty  Purchase
Agreement,  the  Company  purchased  from Agenus  the  right  to  receive  33%  of  the  future  royalties  on  six  Incyte  immuno-oncology  assets,  currently  in  development,  due  to
Agenus  from  Incyte  Europe  Sarl  (“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
the  clinical  trials.  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 an undisclosed Merck 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 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 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”) (see Note 9).

As  of  December  31,  2018,  the  Company  recorded  $15.0  million  as  long-term  royalty  receivables  in  its  consolidated  balance  sheet.  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 of $15.0 million 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
equivalents, trade receivable 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 similar assets or liabilities, that are not active or other inputs that
are not 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

During the years ended December 31, 2018 and 2017, there were no transfers between Level 1, Level 2, or Level 3 assets reported at fair value on a recurring basis and

the valuation techniques used did not change compared to the Company’s established practice.

The following table provides a summary of changes in the estimated fair value of the Company’s Level 3 financial assets for the year ended December 31, 2018 (in

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, 2018. The long-term equity securities are revalued each reporting period with changes in fair value recorded in other income, net line item of the consolidated statement of
operations  and  comprehensive  (loss)  income.  The  Company  and  its  valuation  specialist  used  a  probability-weighted  expected  return  model  to  measure  the  fair  value  of  the
securities.  This  valuation  methodology  is  based  on  unobservable  estimates  and  judgements,  and  therefore  is  classified  as  a  Level  3  fair  value  measurement.  Scenarios  and
probabilities were based on the Company’s management estimates and were incorporated into the determination of the fair value of the equity securities.

On November 4, 2015, XOMA and Ology Bioservices, Inc. (“Ology Bioservices”) entered into an asset purchase agreement under which Ology Bioservices agreed to
acquire  XOMA’s  biodefense  business  and  related  assets  (including  certain  contracts  with  the  U.S.  government),  and  to  assume  certain  liabilities  of  XOMA. As  part  of  the
transaction, the parties entered into an intellectual property license agreement (the “Ology Bioservices License Agreement”), under which XOMA agreed to license to Ology
Bioservices certain intellectual property rights related to the purchased assets. Under the Ology Bioservices License Agreement, the Company was eligible to receive contingent
consideration up to a maximum of $4.5 million in cash and 23,008 shares of common stock of Ology Bioservices, based upon Ology Bioservices achieving certain specified
future operational objectives. In addition, the Company is eligible to receive 15% royalties on net sales of any future Ology Bioservices products covered by or involving the
related patents or know-how.

In February 2017, the Company executed an Amendment and Restatement to both the asset purchase agreement and Ology Bioservices License Agreement primarily to
(i) remove the obligation to issue 23,008 shares of Ology Bioservices under the asset purchase agreement, and (ii) revise the payment schedule related to the timing of the $4.5
million  cash  payments  due  to  the  Company  under  the  Ology  Bioservices  License Agreement.  Of  the  $4.5  million,  $3.0  million  was  contingent  upon  Ology  Bioservices
achieving certain specified future operating objectives. In the first quarter of 2017, the Company became entitled to receive $1.6 million under the agreement that was received
in quarterly payments through September 2018. In the third quarter of 2017, Ology Bioservices achieved the specified operating objectives and the Company earned the $3.0
million milestone fee that was received in monthly payments through July 2018. Based on the payment terms pursuant to the amended Ology Bioservices License Agreement,
the Company is entitled to receive an aggregate of $4.6 million. The Company received $2.4 million during the year ended December 31, 2018, and $2.2 million during the
year ended December 31, 2017, which was recognized as other income, net in the consolidated statements of operations and comprehensive (loss) income. No further payments
remain under the agreement, but the Company is still eligible to receive royalties in the future.

8. Restructuring Charges

On December 19, 2016, the Board of Directors approved a restructuring of its business based on its decision to focus the Company’s efforts on clinical development,
with an initial focus on the X358 clinical programs. The restructuring included a reduction-in-force in which the Company terminated 57 employees (the “2016 Restructuring”).
In early 2017, the Company further revised its strategy to prioritize out-licensing activities and further curtail research and development spending and terminated five additional
employees (the “2017 Restructuring”). Charges related to these initiatives were complete by the end of fiscal 2017.

During the year ended December 31, 2017, the Company recorded charges of $3.4 million related to severance, other termination benefits and outplacement services in

connection with the workforce reduction resulting from the 2017 Restructuring and 2016 Restructuring activities.

During the year ended December 31, 2018, the Company completely vacated both of its leased facilities in Berkeley, California and subleased the leased space to three
subtenants. In connection with vacating this space, the Company recorded a discounted lease-related restructuring liability, which was calculated as the present value of the
estimated future facility costs for which the Company would obtain no future economic benefit over the term of the lease, net of estimated future sublease income, and adjusted
for  the  remaining  balance  of  deferred  rent  of  $0.7  million.  The  Company  remeasured  the  restructuring  liability  based  on  changes  to  the  timing  and  amount  of  actual  and
estimated future sublease income, which resulted in a lease-related restructuring liability of $1.4 million as of December 31, 2018. During the year ended December 31, 2018,
the Company recorded lease-related restructuring charges of $1.3 million in its consolidated statements of operations and comprehensive loss.

In addition, in connection with the sublease agreement executed in April 2018, the Company recognized a loss on the sublease of $0.6 million, which was recorded in

the restructuring charges line item of the consolidated statements of operations and comprehensive loss (see Note 14).

The Company classified the current portion of the combined lease-related liabilities of $1.4 million within accrued and other liabilities and the non-current portion of

$0.3 million within other liabilities- non-current in its consolidated balance sheet as of December 31, 2018.   

9. 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 may make advances (each, a “Term Loan Advance”) available to the Company up to $20.0 million (the “Term Loan”). The available fund may be
increased up to $40.0 million upon the Company’s request and approval by the bank subject to the Company’s compliance with certain internal and credit requirements. The
Company may 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”). Unless an event of
default occurs, the period to draw may be extended to March 31, 2020, if the Company receives $20.0 million in gross cash proceeds from milestone/licensing payments by
March  31,  2019.  In  the  event  of  a  default  related  to  the  Note Agreement  with  Novartis,  SVB’s  obligation  to  make  any  credit  extensions  to  the  Company  under  the  Loan
Agreement will immediately terminate. The interest rate will be calculated at a rate equal to the greater of (i) 4.75%, and (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.

F-24

 
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 Warran t issued to SVB was determined using the Black-Scholes Model and
was estimated to be $0.1 million. As of December 31, 2018, the Warrant is outstanding. In addition, the Company incurred debt issuance costs of $0.2  million  in  connection
with the Loan Agreement.

As of December 31, 2018, the Company has borrowed advances of $7.5 million under the Loan Agreement in connection with the Agenus royalty purchase agreement

(see Note 5). As of December 31, 2018, the outstanding balance under the Loan Agreement was $7.3 million.

During  the  year  ended  December  31,  2018,  the  first  Term  Loan Advance  was  drawn,  and  the  entire  unamortized  amount  of  deferred  charges  of  $0.3  million  was
reclassified as a discount against the debt and will be amortized to interest expense over the term of the Term Loan Advance using the effective interest method. The Company
recorded $0.1 million of non-cash interest expense resulting from the amortization of the discount and accretion of the final payment for the year ended December 31, 2018.

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 accrued at six-month LIBOR plus 2%, which
was equal to 4.87% at December 31, 2018 is payable semi-annually in June and December of each year. Additionally, the interest rate resets in June and December of each year.
At the Company’s election, the semi-annual interest payments could be added to the outstanding principal amount, in lieu of a cash payment, as long as the aggregate principal
amount did not exceed $50.0 million. The Company made this election for all interest payments. Loans under the Note Agreement were 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 will 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 XOMA-052 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.  

As  of  December  31,  2018  and  December  31,  2017,  the  outstanding  principal  balance  under  the  Secured  Note Amendment  was  $15.2  million  and  $14.6  million,

respectively, and was included in long-term debt in the accompanying consolidated balance sheets.

Servier Loan Agreement

In December 2010, in connection with the collaboration agreement entered into with Servier, the Company executed a loan agreement with Servier (the “Servier Loan
Agreement”), which provided for an advance of €15.0 million (or $19.5 million at the exchange rate on the date of funding). The loan was secured by an interest in XOMA’s
intellectual property rights to VPM087and its use in indications worldwide, excluding certain rights in the U.S. and Japan. Interest was calculated at a floating rate based on a
Euro Inter-Bank Offered Rate (“EURIBOR”) and subjected to a cap.

The  Company  and  Servier  executed  multiple  amendments  to  the  Servier  Loan Agreement  in  2015  and  2017  primarily  to  revise  the  timing  of  the  payments  and  the
maturity date of the loan.  On August 25, 2017, NIBR settled the Servier Loan in cash by paying directly to Servier $14.3 million which represented the outstanding balance of
the loan based on a euro to dollar exchange rate of 1.1932. The funds that NIBR paid directly to Servier were a portion of the upfront payment due to XOMA under the XOMA-
052  License  Agreement  (see  Note  4).  As  a  result  of  the  debt  being  fully  paid,  the  intellectual  property  securing  the  Servier  Loan  Agreement  was  released.  A  loss  on
extinguishment  of  $0.1  million  from  the  payoff  of  the  loan  was  recognized  in  the  consolidated  statement  of  operations  and  comprehensive  income  during  the  year  ended
December 31, 2017.

Hercules Term Loan

On February 27, 2015, the Company entered into a loan and security agreement with Hercules Technology Growth Capital, Inc. (the “Hercules Term Loan”).

On March 21, 2017, the Hercules Term Loan was paid in full and the Company was not required to pay the 1% prepayment charge due pursuant to the terms of the loan.
A loss on extinguishment of $0.5 million from the payoff of the Hercules Term Loan was recognized in the consolidated statement of operations and comprehensive income
during the year ended December 31, 2017.

In connection with the Hercules Term Loan, the Company issued unregistered warrants that entitle Hercules to purchase up to an aggregate of 9,063 unregistered shares
of XOMA common stock at an exercise price equal to $66.20 per share. These warrants were exercisable immediately and have a five-year term expiring in February 2020. As
of December 31, 2018, all of these warrants were outstanding.

Interest Expense

Amortization of debt issuance costs and discounts are included in interest expense. Interest expense in the consolidated statements of operations and comprehensive

(loss) income for the years ended December 31, 2018 and 2017, relates to the following debt instruments (in thousands):

10. Income Taxes

The Company has $0.1 million income tax benefit for the year ended December 31, 2018 related to prior year return to provision adjustment and $1.7 million of income
tax  expense  for  the  year  ended  December  31,  2017.  The  Company  is  subject  to  an  ownership  change  pursuant  to  IRC  Section  382  that  occurred  in  February  2017,  which
significantly limited its ability to use its net operating loss carryforwards and tax credits against its 2017 taxable income.

The provision (benefit) for income taxes (all current) consists of the following (in thousands):

The net increase (decrease) in the valuation allowance was $5.8 million and $(166.1) million, for the years ended December 31, 2018 and 2017, 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.

On December 22, 2017, the Tax Cuts and Jobs Act of 2017 (the “Tax Act”) was signed into law making significant changes to the Internal Revenue Code. Changes
include, but are not limited to, a corporate tax rate decrease from 35% to 21% effective for tax years beginning after December 31, 2017. At December 31, 2017, the Company
recorded tax related disclosures for the impact of the Tax Act effects using the current available information and technical guidance on the interpretations of the Tax Act. As
permitted by the U.S. Securities and Exchange Commission Staff Accounting Bulletin No. 118 ("SAB 118"), the Company has completed its accounting analysis based on the
guidance,  interpretations,  and  data  available  as  of  December  31,  2018.    No  financial  statement  adjustment  was  made  in  the  fourth  quarter  of  2018  upon  finalization  of  our
accounting analysis.

Based on an analysis under Section 382 of the Internal Revenue Code (which subjects the amount of pre-change Net Operating Losses ("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, 2017 and December 31, 2018. 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, 2018, the Company had federal net operating loss carry-forwards of approximately $48.8 million and state net operating loss carry-forwards of
approximately $39.1 million to offset future taxable income. The net operating loss carryforwards begin to expire in 2036 for federal and 2033 for state purposes. The Company
had federal orphan credit of $1.2 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 Tax Act, although the treatment of tax losses generated in taxable years ending before December 31, 2017 has generally not changed, tax losses generated in

taxable years beginning after December 31, 2017 can be carried forward indefinitely but may only be utilized to offset 80% of taxable income annually.  

The Company files income tax returns in the U.S. federal jurisdiction, California, Maryland and Texas. The Company’s federal income tax returns for tax years 2015
and  beyond  remain  subject  to  examination  by  the  Internal  Revenue  Service.  The  Company’s  state  income  tax  returns  for  tax  years  2014  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, 2018, the Company had a total of $4.5 million of net 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, 2018, the Company has not accrued interest or penalties related to
uncertain tax positions.

11. 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,  with  the  exception  of  the  first  offering  period,  which  ran  from  July  1,  2015  through  November  30,  2015,  as  the  Company
transitioned from the 1998 ESPP. At the end of each offering period, employees are able to purchase shares at 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.

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, 2018 and 2017, employees purchased 2,948 and 5,314 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  2018  of
$18,500 (or $24,500 for employees over 50 years of age) and for 2017 of $18,000 (or $24,000 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 year ended December 31, 2018, and 100% was paid in common stock for the year. The Company applies shares
from plan forfeitures of terminated employees toward the Company’s matching contribution. For the year ended December 31, 2017, the forfeitures exceeded the total matching
contribution from the Company. Therefore, no expense was recognized by the Company.

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 stock holders 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.

F-29

 
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, 2018, the Company had 341,540 shares available for grant under the stock option plan. As of December 31, 2018, options and RSUs covering

1,627,591 shares of common stock were outstanding under the stock option plan.

Stock Options

Stock options generally vest monthly over three to four 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.

Performance-Based Stock Options

In February 2017, the Board of Directors approved a grant of 1,018,000 stock options to members of the Board of Directors, executives, and non-executive employees,
subject to approval by the Company’s stockholders of an increase in the available shares under the 2010 Plan at the 2017 Annual Meeting of Stockholders. In May 2017, the
shareholders approved the increase in the number of shares available for issuance under the Company’s 2010 Plan and 998,000 stock options were issued upon approval. As
such, the stock options approved for grant in February 2017 were not deemed granted for accounting purposes until May 2017. The stock options granted to the non-employee
board members and non-executive employees vest monthly over three years from the grant date. The stock options granted to the executives contain a combination of time-
based and corporate performance-based vesting conditions.

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.  For the year ended December 31, 2018, certain corporate-based milestones were achieved for 41,250 shares and therefore the
related expense of $0.2 million was recognized during the year. As of December 31, 2018, the Company had 41,250 shares remaining related to outstanding performance-based
stock options with a grant date fair value of $0.2 million. The options are subject to vesting in 2019 based solely on the achievement of fiscal year 2019 corporate goals as set by
the Compensation Committee of the Company’s Board of Directors.

In  December  2017,  the  Company  granted  130,000  stock  options  to  executives  with  corporate  performance-based  vesting  conditions.  During  the  three  months  ended
March 31, 2018, the Board of Directors approved a modification of 80,000 of these options from performance-based vesting to service-based vesting. The remaining 50,000
stock options were cancelled in conjunction with an executive’s resignation.

Series X preferred stock (the “Rights Offering”). In December 2018, the Company sold a total of 285,689 shares of common stock and 1,252.772 shares of Series Y preferred
stock under the Rights Offering for aggregate gross proceeds of $20.0 million. Total offering costs of $0.3 million were offset against the proceeds from the sale of common
stock and preferred stock, for total net proceeds of $19.7 million.

All Series Y convertible preferred shares were issued to Biotechnology Value Fund, L.P. (“BVF”). One of the Company’s Directors, Matthew Perry, is the President of
BVF. Each share of Series Y convertible preferred stock has a stated value of $13,000 per share and is convertible into 1,000 shares of registered common stock based on a
conversion price of $13.00 per share of common stock. The total number of shares of common stock issued upon conversion of all issued Series Y convertible preferred stock
will be 1,252,772 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 is initially set at 19.99% of the
total common stock then issued and outstanding immediately following the conversion of such shares. As of December 31, 2018, BVF owned approximately 20.07% of the
Company’s  total  outstanding  shares,  and  if  all  of  the  Series  X  and  Series  Y  convertible  preferred  shares  were  converted,  BVF  would  own  53.5%  of  the  Company’s  total
outstanding common shares. As of December 31, 2018, none of the preferred stock has been converted into shares of the Company’s common stock.

Biotechnology Value Fund Financing 2017

In February 2017, the Company sold 1,200,000 shares of its common stock and 5,003 shares of Series X convertible preferred stock directly to BVF in a registered

direct offering, for aggregate net cash proceeds of $24.8 million.

BVF purchased the shares of common stock from the Company at a price of $4.03 per share, the closing stock price on the date of purchase. Each share of Series X
convertible preferred stock has a stated value of $4,030 per share and is convertible into 1,000 shares of registered common stock based on a conversion price of $4.03 per
share of common stock. The total number of shares of common stock issued upon conversion of all issued Series X convertible preferred stock will 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 is initially set at 19.99% of the total common stock then issued
and outstanding immediately following the conversion of such shares.

Preferred Stock

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.

F-33

 
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.

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 3% of the gross proceeds of any shares of common stock sold under the 2018 ATM Agreement. For the year ended December 31, 2018, the Company
has not sold any shares of common stock under the 2018 ATM Agreement.

2015 ATM Agreement 

On November 12, 2015, the Company entered into an At Market Issuance Sales Agreement (the “2015 ATM Agreement”) with Cowen and Company, LLC (“Cowen”),
under which the Company may offer and sell from time to time at its sole discretion shares of its common stock through Cowen as its sales agent, in an aggregate amount not to
exceed $75 million. Cowen 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, including
without limitation sales made directly on The Nasdaq Global Market, and also may sell the shares in privately negotiated transactions, subject to the Company’s prior approval.
The Company will pay Cowen a commission equal to 3% of the gross proceeds of the sales price of all shares sold through it as sales agent under the 2015 ATM Agreement. For
the year ended December 31, 2018, the Company sold a total of 67,658 shares of common stock under the 2015 ATM Agreement for aggregate gross proceeds of $2.4 million.
Total  offering  costs  of  $0.1  million  were  offset  against  the  proceeds  upon  the  sale  of  common  stock.  For  the  year  ended  December  31,  2017,  the  Company  sold  a  total  of
110,252 shares of common stock under the 2015 ATM Agreement for aggregate gross proceeds of $0.6 million. Total offering costs of $0.2 million were offset against the
proceeds upon sale of common stock. The shares subject to 2015 ATM Agreement were registered on the shelf registration statement on Form S-3 that expired in February
2018.

Common Stock Purchase Agreement

In August 2017, in connection with the XOMA-052 License Agreement, the Company and Novartis entered into a Common Stock Purchase Agreement under which
Novartis purchased 539,131 shares of the Company’s common stock, at a price per share of $9.2742 for the aggregate purchase price of $5.0 million in cash. The fair market
value of the common stock issued to Novartis AG was $4.8 million, based on the closing stock price of $8.93 per share on the effective date of the Common Stock Purchase
Agreement, or August 24, 2017. The excess of the purchase price over the fair market value of the common stock represents a premium of $0.2 million which was accounted for
as additional consideration to the license agreements (see Note 4 for further discussion). The shares issued to Novartis are unregistered securities and the Company agreed to use
commercially reasonable efforts to make and keep public information available and timely file all reports and other documents with the SEC as required of the Company under
the Securities Exchange Act of 1934, as amended.  Under the Common Stock Purchase Agreement, upon a request by Novartis, the Company will use commercially reasonable
efforts  to  register  the  shares  for  resale  under  the  Securities Act  on  a  registration  statement  on  Form  S-3,  to  be  filed  within  60  days  of  the  written  request,  and  will  use
commercially reasonable efforts to keep such registration statement

F-34

 
continuously effective under the Securities Act until the date all of the shares of common stock covered by such registration statement have been sold or can be sold publicly
without restriction or limitation under Rule 144.

In February 2015, the Company issued Hercules five-year warrants in connection with the Hercules Term Loan (see Note 8) that entitle 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 warrants are classified in stockholders’ equity on the
consolidated balance sheets. As of December 31, 2018, all of these warrants were outstanding.

In February 2016, in conjunction with services provided by a third-party consultant, the Company issued a warrant to purchase up to an aggregate of 8,249 unregistered
shares  of  the  Company’s  common  stock  at  an  exercise  price  equal  to  $15.40  per  share.  These  warrants  were  exercisable  immediately  and  have  a  five-year  term  expiring  in
February  2021.  The  estimated  fair  value  of  the  warrants  of  $0.1  million  was  calculated  using  the  Black-Scholes  Model  and  was  classified  in  stockholders’  equity  on  the
consolidated balance sheet. As of December 31, 2018, all of these warrants were outstanding

In  May  2018,  the  Company  issued  SVB  a  warrant  in  connection  with  the  SVB  Loan Agreement  (see  Note  9)  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. The fair value of the warrant issued to SVB was determined using the Black-
Scholes Model and was estimated to be $0.1 million. The warrants are classified in stockholders’ equity on the consolidated balance sheets. As of December 31, 2018, all of
these warrants were outstanding.

14. Commitments and Contingencies

Collaborative Agreements, Royalties and Milestone Payments

The  Company  has  committed  to  make  potential  future  milestone  payments  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 $7.5 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.

Operating Leases

The  Company  leases  two  facilities  in  Berkeley,  California  and  office  equipment  under  operating  leases  expiring  on  various  dates  through April  2023.  These  leases

require the Company to pay taxes, insurance, maintenance and minimum lease payments.  

In September 2017, the Company entered into a third lease agreement for an office facility in Emeryville, California. The lease has a term of 63 months and commenced

on November 14, 2017. Under the lease agreement the Company will make total lease payments of $0.8 million through February 2023.

Total rental expense, including other costs required under the Company’s leases, was approximately $2.1 million and $2.4 million for the years ended December 31,
2018 and 2017, respectively. Rental expense based on leases allowing for escalated rent payments are recognized on a straight-line basis. At the expiration of the lease, the
Company is required to restore certain of its leased property to certain conditions in place at the time of lease inception.

On  November  21,  2017,  the  Company  entered  into  a non-cancellable sublease  agreement  for  a  portion  of  one  of  its  three  leased  facilities.  The  term  of  the  sublease
agreement commenced on December 26, 2017. Under the term of the sublease agreement, the Company will receive $5.1 million in base lease payments plus reimbursement of
certain operating expenses over the term of the sublease, which ends at the same time as the original lease in April 2023. Under the sublease agreement, the Company’s future
sublease  income  will  be  equal  to  the  amount  required  to  be  paid  to  the  Company’s  landlord. In addition, the  sublease provides for  a  tenant  improvement  allowance  of  $0.8
million to the subtenant, which was funded by the Company in January 2018. Upon execution of the sublease agreement, the Company recognized a loss on the sublease equal to
the tenant improvement allowance. Under the sublease agreement, the sub-lessee executed a standby letter of credit naming the Company as the beneficiary amounting to $1.0
million as security under the sublease in the event of uncured default by the sub-lessee. As of December 31, 2018, the Company has not drawn any funds from the letter of
credit as there was no default by the sub-lessee. During the year ended December 31, 2018, the Company recognized $1.5 million of sublease income under this agreement.

On April 14, 2018, the Company entered into a non-cancellable sublease agreement for a portion of one of its three leased facilities. The term of the sublease agreement
commenced on May 1, 2018. Under the term of the sublease agreement, the Company will receive $1.1 million in base lease payments plus reimbursement of certain operating
expenses over the term of the sublease, which ends at the same time as the original lease in April 2023. Under the sublease agreement, the Company’s future sublease income is
less than the amount required to be paid to the Company’s landlord. In addition, the sublease provides for a tenant improvement allowance of $65,000 to the subtenant, and
payment of broker commissions of $89,000. Upon execution of the sublease agreement, the Company recognized a loss on the sublease of $0.6 million, which was recorded in
the restructuring charges line item of the consolidated statements of operations and comprehensive loss. During the year ended December 31, 2018, the Company recognized
$0.3 million of sublease income under this agreement.

In October 2018, the Company entered into a non-cancellable sublease agreement for a portion of one of its three leased facilities. The term of the sublease agreement
commenced on October 24, 2018. Under the term of the sublease agreement, the Company will receive $1.7 million in base lease payments over the term of the sublease, which
ends at the same time as the original lease in May 2021. Under the sublease agreement, the Company’s future sublease income is less than the amount required to be paid to the
Company’s landlord. In addition, the sublease provides for payment of broker commissions of $137,000. As the sublease agreement was executed after the Company met the
criteria  of  a  cease-use  date  for  the  leased  faciality,  the  Company  did  not  recognize  a  loss  on  the  sublease.  Instead,  the  Company  remeasured  the  lease-related  restructuring
liability  based  on  actual  sublease  income  from  the  sublease  agreement  (see  Note  8)  and  the  resulting  adjustment  was  recorded  in  the  restructuring  charges  line  item  of  the
consolidated statements of operations and comprehensive loss.

Effective January 1, 2019, the Company’s Board of Directors (the “Board”) elected Barbara Kosacz, J.D., a partner of Cooley, LLP (“Cooley”) and the international
head of its life sciences practice, to the Board.  Cooley serves as the Company’s outside legal counsel.  During the years ended December 31, 2018 and 2017, the Company
paid Cooley an aggregate of $0.7 million and $1.5 million, respectively; these amounts are substantially less than five percent of Cooley’s gross revenues for the related fiscal
years.

Rezolute

On January 7, 2019, the Company 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 XOMA 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 XOMA totaling $8.5 million following the closing of a Qualified Financing on or before specified staggered future
dates (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 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 accordance with the terms of the license agreement, XOMA will receive $5.5 million
in cash upon the closing of the Qualified Financing which is additional to the amounts referenced directly above.

In addition, the license agreement amendment 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 XOMA in accordance with the new provisions regarding the Future Cash Payments in the license agreement.

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.

SVB Loan Agreement

On March 4, 2019, the Company and SVB amended the Loan Agreement entered into on May 7, 2018. The Loan Agreement was amended to extend the Draw Period

AMENDMENT NO.2 TO THE
LICENSE AGREEMENT

Exhibit 10.71

THIS  AMENDMENT  NO.  2 (this  "Amendment")  to  that  certain  License Agreement  dated  as  of  December  6,  2017,  by  and  between  XOMA  (US)  LLC,  a
Delaware limited liability company ("XOMA"), having an address of 2200 Powell Street, Suite 310, Emeryville, CA 94608 and Rezolute, Inc. (formerly known as AntriaBio,
Inc.), a Delaware corporation ("Rezolute"), having an address of 1450 Infinite Drive, Louisville, CO 80027, as amended by Amendment No. 1 dated March 30, 2018 (the
"License Agreement"),  is  entered  into  by  and  between  XOMA  and  Rezolute  effective  as  of  January  7,  2019  (the  "Effective  Date").  Each  of  XOMA  and  Rezolute  may  be
referred to herein as a "Party", or jointly as the "Parties". Terms used but not otherwise defined herein shall have the meanings ascribed to them in the License Agreement.

WHEREAS, the Parties desire to amend the License Agreement to revise certain provisions of the License Agreement, including the consideration to be paid to
XOMA upon Rezolute's completion of a Qualified Financing, the assignment and assumption by Rezolute of the AGC Agreement (as defined below), the reimbursement to
XOMA by Rezolute of certain patent expenses, Rezolute's required annual development expenses and level of diligence efforts, and cancellation of XOMA's right to a seat on
Rezolute's Board of Directors;

NOW, THEREFORE, in consideration of the foregoing premises and the mutual covenants herein contained and other good and valuable consideration the receipt

and sufficiency of which are hereby acknowledged, the Parties agree as follows:

Section 1. Amendments. The following sections of the License Agreement are hereby amended as follows:

(a)

Sections 2.1.2 is hereby amended and restated to read in its entirety as  follows:

The Parties have agreed that the financial consideration to be paid to XOMA in exchange for the rights granted and materials transferred hereunder will be
largely  deferred  until  such  time  as  Rezolute  has  substantially  advanced  the  Development  of  the  Antibody  and  Licensed  Products  and  commenced
commercialization  of  Licensed  Products,  such  that  XOMA  is  reliant  on  Rezolute’s  diligent  Development  of  the  Antibody  and  Licensed  Products  and
commercialization  of  the  Licensed  Products  to  fully  receive  the  benefit  of  its  bargain.  Further,  Rezolute  acknowledges  that  the  diligent  conduct  of  such
Development requires the commitment by Rezolute of an appropriate level of funding directed to such Development. Accordingly, and without limiting the
generality of Section 2.1.1, (a) Rezolute (together with its Affiliates and sublicensees) shall expend at least [*] during calendar year 2019 in direct out of
pocket costs (and without the inclusion of overhead) on the Development of the Antibody and Licensed Products; and (b) Rezolute shall use Diligent Efforts,
itself or through an Affiliate or sublicensee, to dose the first patient in the Phase 2 Repeat Dose Study by [*].

(b) The first sentence of Section 2.3.6 is hereby amended and restated to read as follows:

The Parties shall share all Tech Transfer Expenses as follows: XOMA shall pay the first $275,000 of all Tech Transfer Expenses and Rezolute shall be solely
responsible for all Tech Transfer Expenses above $275,000.

(c) New Section 2.3.7 is hereby added to the License Agreement to read in its entirety as follows:

2.3.7 Payments; Assignment of AGC Agreement . Within thirty (30) days after January 7, 2019, Rezolute shall (a) reimburse XOMA for [*] in patent-related
maintenance costs incurred as of such date, and (b) pay XOMA [*] associated with the occurrence of any Qualified Financing delay described in 4.7.1 below.
Within sixty (60) days after January 7, 2019: (a) XOMA and Rezolute shall use their best efforts to enter into an assignment and assumption agreement with
[*]  whereby  XOMA  shall  assign  to  Rezolute  and  Rezolute  shall  assume  that  [*],  by  and  between  XOMA  and  [*]  and  all  accompanying  Work  Statements
(collectively,  the  “[*]”)  and  cause  XOMA  to  be  released  from  any  and  all  rights  and  obligations  under  the  [*];  and  (b)  XOMA  shall  make  commercially
reasonable efforts to transfer the IND for the fully human allosteric modulating monoclonal antibody formerly known as XOMA 358 (now known as RZ358)
to  Rezolute.  Unless  and  until  [*]  assigns  the  [*]  to  Rezolute  in  full  in  good  order  and  [*]  fully  releases  XOMA  from  all  obligations  thereunder  (the
“Assignment”), after XOMA pays the first $275,000 of Tech Transfer Expenses, Rezolute shall pay all amounts due under the [*] promptly upon receipt of an
invoice from AGC or XOMA related thereto and shall be the primary obligor of payments thereunder.

(d) Section 4.6 of the License Agreement is hereby amended to read in its entirety as follows:

 4.6 Qualified Financing. Within fifteen (15) days following the closing of the Qualified Financing, Rezolute shall pay XOMA the greater of (a) [*] of the net
proceeds from the Qualified Financing and (b) Six Million Dollars ($6,000,000). Following the closing of the Qualified Financing, Rezolute shall make the
following five (5) cash payments to XOMA

No later than June 30, 2020

TOTAL: $8,500,000

In addition, to provide a potential for early payment and only until the above $8.5M total is reached, Rezolute shall make ongoing future cash payments to
XOMA in an amount equal to fifteen percent (15%) of the net proceeds from each future financing following the closing of the Qualified Financing, which
amounts  shall  be  credited  against  the  Future  Cash  Payments  in  reverse  order  of  their  timing  and  to  end  after  the  Future  Cash  Payments  are  made  (e.g.,
Payment #5 will be credited first, followed by Payment #4, etc. and this mechanism will end after the above $8.5M total is reached).

(e)

Sections 4.7.2, 4.7.3 and 4.9 of the License Agreement are hereby  deleted.

(f)

New Section 12.16 is added to the License Agreement to read in its entirety as follows:

hereto.

Section 2. Effect of Amendment. Except as expressly provided for herein, all terms and conditions of the License Agreement shall remain in full force and effect.
