In the ordinary course of our business, we enter into leases with unaffiliated parties for the use of (i) office and research facilities and (ii) office equipment. Our current leases have remaining terms ranging from less than one year to four years and none include any residual value guarantees, restrictive covenants, term extensions, or early-termination options.

We lease our principal executive office in Henderson, Nevada under a non-cancelable operating lease expiring October 31, 2022. We also lease our research and development facility in Irvine, California under a non-cancelable operating lease expiring July 31, 2022, in addition to other administrative office leases. We also lease an office facility in Boston under a non-cancelable operating lease expiring December 31, 2024.

Our facility leases have minimum annual rents, payable monthly, and some carry fixed annual rent increases. Under some of these arrangements, real estate taxes, insurance, certain operating expenses, and common area maintenance are reimbursable to the lessor. These amounts are expensed as incurred, as they are variable in nature and therefore excluded from the measurement of our reported lease asset and liability discussed below. As of March 31, 2022 and 2021, we had no sublease arrangements with us as lessor, and no finance leases, as defined in ASU 2016-02, Leases (“Topic 842”).

The reported asset and liability, respectively, represents (i) the economic benefit of our use of leased facilities and equipment and (ii) the present-value of our contractual minimum lease payments, applying our estimated incremental borrowing rate as of the lease commencement date (since an implicit interest rate is not readily determinable in any of our leases). The recorded asset and liability associated with each lease is amortized over the respective lease term using the effective interest rate method. During the three months ended March 31, 2022 and 2021, we recognized no additional ROU assets in exchange for lease liabilities.

The in-license agreements for our development-stage drug products provide us with territory-specific rights to their manufacture and distribution (including further sub-licensing/out-licensing rights). We are generally responsible for all related clinical development costs, patent filings and maintenance costs, marketing costs, and liability insurance costs. We also may enter into out-license agreements for territory-specific rights to these drug products which include one or more of: upfront license fees, royalties from our licensees’ sales, and/or milestone payments from our licensees’ sales or regulatory achievements. For certain drug products, we may enter into cost-sharing arrangements with licensees and licensors.

We are also obligated to make specified milestone payments to our licensors upon the achievement of certain regulatory and sales milestones, and to pay royalties based on our net sales of all in-licensed products. Depending on the milestone achievement type and whether the product has been approved, we will either (a) capitalize the value to “intangible assets” in the Consolidated Balance Sheets or (b) recognize the payment value within “research and development” or “cost of sales” on the Consolidated Statements of Operations. The liability relating to the payment due to the licensor will be recognized in the earliest period that we determine the respective milestone achievement is probable or occurs.

In October 2014, we exercised our option under a License Option and Research Collaboration Agreement dated January 2012 (as amended) with Hanmi for eflapegrastim, a drug based on Hanmi’s proprietary LAPSCOVERY™ technology for the treatment of chemotherapy induced neutropenia. Under the terms of this agreement, as amended, we have primary financial responsibility for the eflapegrastim development plan and hold its worldwide rights (except for Korea, China, and Japan).

Effective January 1, 2022, we executed an amendment to this license agreement, whereby we are contractually obligated to pay Hanmi a flat mid-single digit royalty on our aggregate annual net sales of eflapegrastim. Hanmi has agreed to release the Company from a prior purchase obligation for eflapegrastim drug substance which resulted in a reduction in accrued liabilities of $11.2 million with a corresponding reduction in research and development expense. In addition, beginning in year three after the commercial launch, we are responsible for a supplemental mid-single digit royalty on aggregate annual net sales. This supplemental royalty will terminate once the aggregate payments made to Hanmi meet the milestone limit of $10 million, based on the supplemental royalty. There were no obligations to Hanmi for the three months ended March 31, 2022.

In February 2015, we executed an in-license agreement with Hanmi for poziotinib, a pan-HER inhibitor in Phase 2 clinical trials, (which has also shown single agent activity in the treatment of various cancer types during Phase 1 studies, including breast, gastric, colorectal, and lung cancers) and made an upfront payment to Hanmi for these distribution rights. Under the terms of this agreement, we received the exclusive global rights to commercialize poziotinib, except for Korea and China. Hanmi and its development partners are fully responsible for the completion of on-going Phase 2 trials in Korea. We are financially responsible for all other clinical studies.

Effective January 1, 2022, we executed an amendment to this in-license agreement, whereby the payments to Hanmi upon our achievement of various regulatory milestones now aggregate to $18 million, which includes eliminating the first approval milestone payment in return for a supplemental mid-single digit royalty on aggregate annual net sales beginning in year three after the commercial launch. This supplemental royalty will terminate once the aggregate payments made to Hanmi meet the milestone limit of $15 million, based on the supplemental royalty. There were no contractual obligations to Hanmi under the previous agreement for the three months ended March 31, 2022.

In April 2018, we executed an exclusive patent and technology agreement for the use of poziotinib in treating patients with EGFR and HER2 exon 20 mutations in cancer and HER2 exon 19 mutations in cancer with The University of Texas M.D. Anderson Cancer Center (“MD Anderson”). MD Anderson discovered poziotinib’s use in treating these patient-types. We made an upfront payment to MD Anderson of $0.5 million upon the execution of this agreement.

We are contractually obligated to pay nominal fixed annual license maintenance fees to MD Anderson and pay additional fees upon our achievement of various regulatory and sales milestones. These regulatory milestones aggregate $6 million and the sales milestones aggregate $24 million. We are also contractually obligated to pay MD Anderson royalties in the low single-digits on our net sales of poziotinib.

In April 2019, we executed an asset transfer, license, and sublicense agreement with ImmunGene, Inc. (“ImmunGene”) for an exclusive license for the intellectual property related to (a) Anti-CD20-IFNα, an antibody-interferon fusion molecule directed against CD20 that is in Phase 1 development for treating relapsed or refractory non-Hodgkin’s lymphoma, including diffuse large B-cell lymphoma patients, representing a considerable unmet medical need, and (b) an antibody-interferon fusion molecule directed against GRP94, a target for which currently there are no existing approved therapies that have the potential for treating both solid and hematologic malignancies. Both molecules are based on the Focused Interferon Therapeutics (“FIT”) drug delivery platform.

In November 2021, we provided notice to terminate the asset transfer, license, and sublicense agreement with ImmunGene, Inc. Pursuant to the agreement, we will transfer the rights, title or interest with respect to the transferred product back to ImmunGene. There were no contractual obligations to ImmunGene for the three months ended March 31, 2022.

In December 2020, we executed an asset transfer and license agreement with Therapyx, Inc. (“Therapyx”) for an exclusive worldwide license for the intellectual property related to any pharmaceutical or biological product for use in human oncology containing, whether as its sole active or in combination with other active ingredients, an encapsulated IL-12, in any injectable dosage form or formulation.

We made an upfront payment of $0.8 million to Therapyx upon contract execution, which was recorded to “research and development” expense within our Consolidated Statements of Operations for the year ended December 31, 2020. We will make an additional payment of $2.2 million upon our acceptance of certain transferred materials from Therapyx. We will make further payments to Therapyx upon our achievement of various (i) regulatory milestones aggregating up to $30 million for the first approved IL-12 product, plus an additional $2.5 million milestone payment for each new indication approved for each product in the U.S., Europe, or Japan; and (ii) sales milestones aggregating up to $167.5 million based on worldwide annual net sales. We are contractually obligated to pay royalties in the mid-single digits on our net sales of all IL-12 products, potentially reduced by royalties due to third parties, the loss of IP protection within one or more countries, or the introduction of a competing product within one or more countries.

Depending on the nature of the milestone achievement type we will either (a) capitalize the payment value to “intangible assets” in the Consolidated Balance Sheets or (b) recognize the payment value within “research and development” or “cost of sales” within the Consolidated Statements of Operations. The corresponding liability for the payment due to this licensor will be recognized in the Consolidated Balance Sheets within “accounts payable and other accrued liabilities” in the earliest period that we determine the respective milestone achievement is probable or occurs.

We have entered into various contracts with numerous third-party service providers for the execution of our research and development initiatives. These vendors include raw material suppliers, clinical trial sites, clinical research organizations, and data monitoring centers, among others. The financial terms of these agreements are varied and generally obligate us to pay in stages, depending on the achievement of certain events specified in the agreements - such as contract execution, progress of service completion, delivery of drug supply, and the dosing of patients in clinical studies.

We recognize these “research and development” expenses and corresponding “accounts payable and other accrued liabilities” in the accompanying financial statements based on estimates of our vendors’ progress of performed services, patient enrollments and dosing, completion of clinical studies, and other events. Should we decide to discontinue and/or slow-down the work on any project, the associated costs for those projects would typically be limited to the extent of the work completed, as we are generally able to terminate these contracts with adequate notice.

We entered into revised employment agreements with each of our named executive officers (chief executive officer, chief operating officer, chief financial officer, chief legal officer, and chief medical officer) in April/June 2018 and June 2019, which supersede any prior change in control severance agreements with such individuals. These agreements provide for the payment of certain benefits to each executive upon his separation of employment under specified circumstances. These arrangements are designed to encourage each to act in the best interests of our stockholders at all times during the course of a change in control event or other significant transaction.

We previously entered into an employment agreement with our former Chief Executive Officer, Joseph Turgeon, under which cash compensation and benefits would become payable in the event of termination by us for any reason other than cause, his resignation for good reason, or upon a change in control of our Company. Effective December 31, 2021, Mr. Turgeon’s employment with the Company was terminated without cause in accordance with his employment agreement. We have accrued $2.6 million and $3.1 million for all contractual amounts due and unpaid to Mr. Turgeon as of March 31, 2022 and December 31, 2021, respectively, within "accrued payroll and benefits" on the accompanying Consolidated Balance Sheets.

The DC Plan is maintained to provide special deferred benefits for a select group of our employees (the “DC Participants”). DC Participants make annual elections to defer a portion of their eligible cash compensation which is then placed into their DC Plan accounts. We match a fixed percentage of these deferrals, and may make additional discretionary contributions. At March 31, 2022 and December 31, 2021, the aggregate value of this DC Plan liability was $10.5 million and $11.2 million, respectively, and is included within “accounts payable and other accrued liabilities” and “other long-term liabilities” in the accompanying Condensed Consolidated Balance Sheets.

We are involved from time-to-time with various legal matters arising in the ordinary course of business. These claims and legal proceedings are of a nature we believe are normal and incidental to a pharmaceutical business, and may include product liability, intellectual property, employment matters, and other general claims. We may also be subject to derivative lawsuits from time to time.

We make provisions for liabilities when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. Such provisions are assessed at least quarterly and adjusted to reflect the impact of any settlement negotiations, judicial and administrative rulings, advice of legal counsel, and other information and events pertaining to a particular case. Litigation is inherently unpredictable. Although the ultimate resolution of these various matters cannot be determined at this time, we do not believe that such matters, individually or in the aggregate, will have a material adverse effect on our consolidated results of operations, cash flows, or financial condition.

On May 28, 2021, Bioverativ Therapeutics Inc. (“Bioverativ”) filed a complaint against us in the U.S. District Court for the District of Delaware, which alleges that our proposed manufacture, use and sale of eflapegrastim would, if approved, infringe claims of three patents owned by Bioverativ (the “Subject Patents”). Bioverativ sought an unspecified amount of damages and injunctive relief.

Pursuant to our agreements with Hanmi, we hold worldwide rights (except for Korea, China, and Japan) to develop and commercialize eflapegrastim. The agreements with Hanmi contain typical license terms including, without limitation, indemnification rights in favor of the Company with respect to any claims of infringement from a third party with respect to our use of a licensed technology, product or compound pursuant to such agreements.

Related to the Bioverativ litigation, on December 20, 2021, we were named as respondents in an International Trade Commission (ITC) action filed in the ITC. The complaint alleged importation into the United States, the sale for importation, and the sale within the United States after importation of certain monomer-dimer hybrid immunoconjugates in violation of section 337 of the Tariff Act of 1930 (19 U.S.C. 1337).

On February 18, 2022, Spectrum, Hanmi and Bioverativ entered into a license and settlement agreement which included a stipulation to dismiss the Bioverativ litigation and withdraw the ITC complaint. On February 18, 2022, the ITC action against us was withdrawn, and on March 2, 2022, the Bioverativ case was dismissed by the U.S. District Court.

Luo v. Spectrum Pharmaceuticals, Inc., et al. On August 31, 2021, a shareholder lawsuit was filed against us in the U.S. District Court for the District of Nevada, which alleges that we and certain of our executive officers made false or misleading statements and failed to disclose material facts about our business and the prospects of approval for our BLA to the FDA for eflapegrastim in violation of Section 10(b) (and Rule 10b-5 promulgated thereunder) and 20(a) of the Securities Exchange Act of 1934, as amended. On November 1, 2021, four individuals and one entity filed competing motions to be appointed lead plaintiff and for approval of counsel in this putative securities class action. The plaintiffs seek damages, interest, costs, attorneys’ fees, and other unspecified equitable relief. We believe that these claims are without merit and intend to vigorously defend against these claims. On March 2, 2022, the Court entered an order partially granting and partially denying without prejudice a stipulated order eliminating defendants’ obligation to answer the initial pleading pending an amended complaint and

Csaba v. Turgeon, et. al, (filed December 15, 2021 , in the U.S. District Court District of Nevada); Shumacher v. Turgeon, et. al, (filed March 15, 2022 in the U.S. District Court District of Nevada); and Johnson v. Turgeon, et. al, (filed March 29, 2022 in the U.S. District Court District of Nevada). These putative stockholder derivative actions were filed against us (as a nominal defendant), certain of our executive officers, and certain of our past and present members of the board of directors. The stockholder derivative complaint alleges that certain of our executive officers are liable to Spectrum, pursuant to Section 10(b) and 21(d) of the Securities Exchange Act of 1934, as amended, for contribution and indemnification, if they are deemed (in the Luo class action), to have made false or misleading statements and failed to disclose material facts about our business and the prospects of approval for our BLA to the FDA for eflapegrastim. The complaint further alleges that certain of our executive officers and certain of our past and present directors breached their fiduciary duties, and certain of our present directors negligently violated Section 14(a) of the Exchange Act, by allegedly causing such false or misleading statements to be issued and/or failing to disclose material facts about our business and the prospects of approval for our BLA to the FDA for eflapegrastim. The allegations state that as a result of the violations, certain of our executive officers and past and present board members were unjustly enriched. The plaintiffs seek corporate reforms, damages, interest, costs, attorneys’ fees, and other unspecified equitable relief.
