The Company is filing this Amendment solely for the purposes of including the information required in Part III (Items 10, 11, 12, 13 and 14) of Form 10-K that was previously omitted from the Annual Report in reliance upon General Instruction G(3) to Form 10-K. General Instruction G(3) to Form 10-K allows such omitted information to be filed as an amendment to the Annual Report, or incorporated by reference from the Company’s definitive proxy statement which involves the election of directors, not later than 120 days after the end of the fiscal year covered by the Annual Report. As of the date of this Amendment, the Company does not intend to file a definitive proxy statement containing the information required in Part III of Form 10-K within such 120-day period. Accordingly, the Company is filing this Amendment to include such omitted information as part of the Annual Report.

In accordance with Rule 12b-15 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), Part III, Items 10 through 14 of the Annual Report and Part IV, Item 15 of the Annual Report (other than Schedule II thereto) are hereby amended and restated in their entirety.

Other than as specifically stated herein, this Amendment continues to speak as of the date of the Annual Report, and the Company has not updated the disclosures contained therein to reflect any events which occurred at a date subsequent to the filing of the Annual Report. Accordingly, this Amendment should be read in conjunction with the Annual Report.

Item 11.Executive Compensation.

Compensation Discussion and Analysis

Compensation Philosophy

The primary goals of our Board with respect to executive compensation are to attract and retain talented and dedicated executives, to tie annual and long-term cash and stock incentives to achievement of specified performance objectives, and to create incentives resulting in increased stockholder value. To achieve these goals, our Compensation Committee recommends to our Board executive compensation packages, generally comprising a mix of salary, discretionary bonus and equity awards. Although we have not adopted any formal guidelines for allocating total compensation between equity compensation and cash compensation, we have implemented and maintain compensation plans that tie a substantial portion of our executives’ overall compensation to achievement of corporate goals.

Role of Compensation Consultant

The Compensation Committee has the power to engage independent advisors to assist it in carrying out its responsibilities. In 2018, the Compensation Committee engaged Compensia, Inc. (“Compensia”), a national compensation consulting firm, to review and advise on our compensation practices. The Compensation Committee assessed the independence of Compensia pursuant to SEC rules and concluded that the work of Compensia has not raised any conflict of interest.

In 2018, Compensia undertook the following projects for the Compensation Committee:

• April 2018 - Evaluated the compensation arrangements for the Company’s executive officers against a comparator group of similar life sciences companies and its own proprietary data; and

• April 2018 - Evaluated the compensation arrangements for the members of the Company’s Board of Directors against a comparator group of similar life sciences companies and its own proprietary data.

With respect to the equity awards granted to our Chief Executive Officer in May 2018 and our then-current executive officers other than our Chief Executive Officer in November 2018, the comparator group of life sciences companies consisted of the following companies, which were determined to: (i) generally have similar revenues as us; (ii) generally have similar market capitalization as us, (iii) generally have similar operating income as us, and (iv) generally have the same number of employees as us:

Agenus Inc.	MacroGenics, Inc.
Akebia Therapeutics, Inc.	Momenta Pharmaceuticals, Inc.
ChemoCentryx, Inc.	Omeros Corporation
CytomX Therapeutics, Inc.	PTC Therapeutics, Inc.
Eagle Pharmaceuticals, Inc.	Recro Pharma, Inc.
Inovio Pharmaceuticals, Inc.	Retrophin, Inc.
Keryx Biopharmaceuticals, Inc.	Vanda Pharmaceuticals Inc.
Lexicon Pharmaceuticals, Inc.	Vericel Corporation

In 2018, Compensia reviewed and advised the Compensation Committee on the matters described above.

In setting 2018 compensation, the Compensation Committee reviewed the competitive market analysis provided by Compensia and compared each named executive officer’s base salary, target annual performance bonus and equity compensation value, separately and in the aggregate, to amounts paid to similarly-situated executives at our peer companies. The Compensation Committee believes that targeting compensation towards similarly situated executives at our peer companies helps achieve the compensation objectives described above. However, compensation for each named executive officer may vary from this range

5

depending on other factors the Compensation Committee considers relevant, such as internal pay equity among our named executive officers or levels of authority, responsibility and experience of our named executive officers that exceed the norms for individuals holding comparably-titled positions at other companies.

Elements of Compensation

We evaluate individual executive performance with a goal of setting compensation at levels our Board or any applicable committee thereof believes are comparable with executives in other companies of similar size and stage of development while taking into account our relative performance and our own strategic goals. The compensation received by our named executive officers consists of the following elements:

Base Salary

Base salaries for our executives are established based on the scope of their responsibilities and individual experience, taking into account competitive market compensation paid by other companies for similar positions within our industry.

The Compensation Committee considers compensation data from the peer companies to the extent the executive positions at these companies are considered comparable to our positions and informative of the competitive environment. Compensation data for our peer group were collected from available proxy-disclosed data. This information was gathered and analyzed for the 25th, 50th and 75th percentiles for annual base salary, short-term incentive pay elements and long-term incentive pay elements.

The amended and restated employment agreement between us and Dr. Ji, dated May 9, 2017, provides for an annual base salary for Dr. Ji of $600,000, as may be adjusted from time to time. Based on a review of Dr. Ji’s individual performance since joining us in 2006 and the competitive market base pay data for chief executive officers included in our peer group in the May 2018 Report, effective May 29, 2018, the Compensation Committee increased Dr. Ji’s annual base salary from $600,000 to $670,000 with retroactive effect to January 1, 2018.

The offer letter between us and Mr. Shao, our Executive Vice President and Chief Financial Officer, dated March 15, 2018, provides for an annual base salary for Mr. Shao of $450,000, as may be adjusted from time to time. There were no changes to Mr. Shao’s salary during 2018.

Mr. Ferrigno, our former Chief Accounting Officer (and former principal financial officer), was paid an annual base salary of $225,000 pursuant to an offer letter dated November 1, 2016. Mr. Ferrigno was appointed our Chief Accounting Officer (and principal financial officer) effective May 15, 2017. Mr. Ferrigno’s employment with the Company terminated effective March 23, 2018.

Mr. Ng, our former Executive Vice President, Chief Administrative Officer and Chief Legal Officer, was a party to an employment agreement with us dated December 8, 2014 pursuant to which we paid him an annual base salary of $450,000. Effective April 10, 2018, Mr. Ng's base salary was increased from $450,000 to $468,000, with retroactive effect to January 1, 2018. As of December 31, 2018, Mr. Ng was not considered to be an executive officer of the Company. Mr. Ng became a full-time employee of our subsidiary, Scilex Pharmaceuticals Inc. on September 1, 2018. His employment with the Company and our subsidiaries terminated effective April 1, 2019.

The offer letter between us and Dr. Zeldis, our Chief Medical Officer and President of Clinical Development, dated August 9, 2016, provides for an annual base salary for Dr. Zeldis of $275,000, as may be adjusted from time to time.Effective April 10, 2018, Dr. Zeldis' base salary was increased from $275,000 to $305,000, with retroactive effect to January 1, 2018. As of December 31, 2018, Dr. Zeldis was not considered to be an executive officer of the Company, but he continues to serve as the Company’s Chief Medical Officer and President of Clinical Development.

Variable Pay

We design our variable pay programs to be both affordable and competitive in relation to the market. We monitor the market and adjust our variable pay programs as needed. Our variable pay programs, such as our bonus program, are designed to motivate employees to achieve overall goals. Our programs are designed to avoid entitlements, to align actual payouts with the actual results achieved and to be easy to understand and administer.

2018 Bonuses

6

Under the terms of our amended and restated employment agreement with Dr. Ji, Dr. Ji’s target annual bonus is equal to 55% of his annual salary. Our offer letter with Mr. Shao provides that Mr. Shao’s annual target bonus is equal to 35% of his annual salary. Our offer letter with Mr. Ferrigno provided that Mr. Ferrigno’s annual target bonus was equal to 25% of his annual salary. Our employment agreement with Mr. Ng provided that Mr. Ng’s target annual bonus was equal to 35% of his annual salary. Our offer letter with Dr. Zeldis provides that Dr. Zeldis’ annual target bonus is equal to 40% of his annual salary.

As of this date of the filing of this Annual Report on Form 10-K, the Compensation Committee has not yet determined the annual bonus amounts, if any, that will be awarded our named executive officers for 2018. We expect the Compensation Committee to assess 2018 performance and determine the 2018 annual bonus awards for our executive officers by August 2019. Once such annual bonus amounts, if any, have been determined, we will, in accordance with Securities and Exchange Commission rules and regulations, file a Current Report on Form 8-K or otherwise disclose the 2018 annual bonus amounts within four business days after the Compensation Committee has assessed 2018 performance and determined the 2018 annual bonus awards for our named executive officers.

Equity-Based Incentives

Salaries and bonuses are intended to compensate our executive officers for short-term performance. We also have adopted an equity incentive program intended to reward longer-term performance and to help align the interests of our named executive officers with those of our stockholders. We believe that long-term performance is achieved through an ownership culture that rewards performance by our named executive officers through the use of equity incentives. Our equity incentive plan has been established to provide our employees, including our named executive officers, with incentives to help align those employees’ interests with the interests of our stockholders.

When making equity-award decisions, the Compensation Committee considers market data, the grant size, the forms of long-term equity compensation available to it under our existing plans and the status of previously granted awards. The amount of equity incentive compensation granted reflects the executives’ expected contributions to our future success. Existing ownership levels are not a factor in award determination, as the Compensation Committee does not want to discourage executives from holding significant amounts of our stock.

Future equity awards that we make to our named executive officers will be driven by our sustained performance over time, our named executive officers’ ability to impact our results that drive stockholder value, their level of responsibility, their potential to fill roles of increasing responsibility, and competitive equity award levels for similar positions in comparable companies. Equity forms a key part of the overall compensation for each executive officer and is evaluated each year as part of the annual performance review process and incentive payout calculation.

The amounts awarded to the named executive officers are based on the Compensation Committee’s subjective determination of what is appropriate to incentivize the executives. Generally, the grants to named executive officers vest over: (i) a four-year period with 25% vesting on each anniversary of the grant date, or (ii) a four-year period with 1/4 of the shares vesting on the first anniversary of the applicable vesting commencement date, and 1/48 of the shares vesting thereafter on a monthly basis. All equity awards to our employees, including named executive officers, and to directors have been granted and reflected in our financial statements, based upon the applicable accounting guidance, with the exercise price equal to the fair market value of one share of common stock on the grant date.

In May 2018, the Compensation Committee decided to grant to Dr. Ji a long-term equity based incentive in the form of options to purchase 750,000 shares of our common stock. In November 2018, the Compensation Committee decided to grant long-term equity based incentives in the form of options to purchase shares of common stock to our then-current named executive officers other than our Chief Executive Officer. The Compensation Committee considered the competitive market analysis provided by Compensia and other data in determining the number of options granted to our Chief Executive Officer in May 2018 and our then-current executive officers in November 2018. Mr. Ng became a full-time employee of our subsidiary, Scilex Pharmaceuticals Inc., on September 1, 2018 and therefore did not receive any equity in the Company during fiscal year 2018. In setting the initial option awards granted to Mr. Shao upon commencement of his employment with the Company, the Compensation Committee considered that our executive vice presidents had historically been granted initial options to purchase 200,000 shares and additionally granted Mr. Shao an option to purchase 300,000 shares that will vest only upon the date our common stock is listed on The Stock Exchange of Hong Kong Limited on the basis that Mr. Shao was expected to have an important role in facilitating any listing of our shares in Hong Kong. It is our view that option based awards best align with the interest of our stockholders. The equity awards granted to our named executive officers in 2018 are set forth in the 2018 Summary Compensation Table and Grants of Plan-Based Awards During Fiscal Year 2018 table contained herein.

In order to encourage a long-term perspective and to encourage key employees to remain with us, our stock options typically have annual vesting over a four-year period and a term of ten years. Generally, vesting ends upon termination of services and exercise rights of vested options cease three months after termination of services. Prior to the exercise of an option, the holder has no rights as a stockholder with respect to the shares subject to such option, including voting rights and the right to receive dividends or dividend equivalents.

Benefits Programs

We design our benefits programs to be both affordable and competitive in relation to the market while conforming with local laws and practices. We monitor the market and local laws and practices and adjust our benefits programs as needed. We design our benefits programs to provide an element of core benefits and, to the extent possible, offer options for additional benefits, be tax-effective for employees in each country and balance costs and cost sharing between us and our employees.

Timing of Equity Awards

Only the Compensation Committee may approve stock option grants to our executive officers. Stock options are generally granted at meetings of the Compensation Committee. On limited occasions, a grant may be made pursuant to a unanimous written consent of the Compensation Committee, which occurs primarily for the purpose of approving a compensation package for a newly hired or promoted executive. The exercise price of a newly granted option is the closing price of our common stock on the date of grant.

Executive Equity Ownership

We encourage our executives to hold a significant equity interest in our company. However, we do not have specific share retention and ownership guidelines for our executives.

Hedging Policy

Our Insider Trading and Window Period Policy prohibits our directors, officers and employees, and their family members, from engaging in hedging transactions involving our securities.

Consideration of Advisory Votes to Approve the Compensation of our Named Executive Officers

We value the opinions of our stockholders, including as expressed through advisory votes to approve the compensation of our named executive officers (“Say-on-Pay Votes”). In our most recent Say-On-Pay Vote, conducted at our 2018 annual meeting of stockholders, held on August 24, 2018, our stockholders approved the compensation of our named executive officers on an advisory basis, with approximately 90% of the votes cast in favor of the fiscal 2017 compensation of our named executive officers. In setting fiscal 2018 compensation, we considered the outcome of the Say-on-Pay Vote during our 2018 annual meeting of stockholders and will continue to consider the outcome of future Say-on-Pay Votes, as well as stockholder feedback received throughout the year, when making compensation decisions for our executive officers.

Effect of Accounting and Tax Treatment on Compensation Decisions

In the review and establishment of our compensation programs, we consider the anticipated accounting and tax implications to us and our executives.

Generally, Section 162(m) of the Internal Revenue Code of 1986, as amended (the “Code”), disallows public companies a tax deduction for federal income tax purposes of compensation in excess of $1 million paid to their chief executive officer and certain other specified officers in any taxable year. For tax years ending prior to December 31, 2017, compensation in excess of $1 million could only be deducted if it was “performance-based compensation” within the meaning of Section 162(m) of the Code or qualified for one of the other exemptions from the deduction limit. The exemption from Section 162(m) of the Code’s deduction limit for performance-based compensation has been repealed, effective for taxable years beginning after December 31, 2017, such that compensation paid to our covered officers (which now also includes our Chief Financial Officer) in excess of $1 million will generally not be deductible unless it qualifies for transition relief applicable to certain arrangements in place as of November 2, 2017. We seek to maintain flexibility in compensating our executives in a manner designed to promote our corporate goals and, therefore, while we are mindful of the benefit of the full deductibility of compensation, our Compensation Committee has not adopted a policy requiring that any or all compensation to be deductible. Our Compensation Committee may authorize compensation payments that are not fully tax deductible if we believe that such payments are appropriate to attract and retain executive talent or meet other business objectives.

8

Role of Executives in Executive Compensation Decisions

The Board and our Compensation Committee generally seek input from our Chief Executive Officer, Dr. Ji, when discussing the performance of, and compensation levels for, executives other than himself. The Compensation Committee also works with Dr. Ji and our Chief Financial Officer to evaluate the financial, accounting, tax and retention implications of our various compensation programs. Neither Dr. Ji nor any of our other executives participate in deliberations relating to his compensation.

Compensation Risk Management

We have considered the risk associated with our compensation policies and practices for all employees, and we believe we have designed our compensation policies and practices in a manner that does not create incentives that could lead to excessive risk taking that would have a material adverse effect on us for the following reasons:

• We structure our compensation to consist of base salary, variable pay, equity-based pay and benefits. The base portion of compensation is designed to provide a steady income regardless of our stock price performance so that executives do not feel pressured to focus exclusively on stock price performance to the detriment of other important business measures. Our variable pay and equity-based pay programs are designed to reward both short- and long-term corporate performance. For short-term performance, our variable pay programs are designed to motivate employees to achieve overall goals. For long-term performance, our stock option awards generally vest over four years and are only valuable if our stock price increases over time. We believe that these variable elements of compensation are a sufficient percentage of overall compensation to motivate executives to produce superior short- and long-term corporate results, while the fixed element is also sufficiently high that the executives are not encouraged to take unnecessary or excessive risks in doing so.

• Our bonus program has been structured around attainment of overall corporate goals for the past several years and we have seen no evidence that it encourages unnecessary or excessive risk taking.

SUMMARY COMPENSATION TABLE

The following table provides certain summary information concerning compensation awarded to, earned by or paid to each person who served as our principal executive officer at any time during fiscal year 2018, each person who served as our principal financial officer at any time during fiscal year 2018 and two additional persons who were not serving as our executive officers as of the end of fiscal year 2018 but would have otherwise been required to be included in the following table (collectively, the “named executive officers”).

See “-Elements of Compensation-Variable Pay-2018 Bonuses” above for a discussion of the target bonus amounts for each named executive officer for fiscal year 2018. We expect the Compensation Committee to assess 2018 performance and determine the 2018 annual bonus awards for our executive officers by August 2019.

Employment, Severance, Separation and Change in Control Agreements

Chief Executive Officer Employment Agreement

On May 9, 2017, we entered into an Amended and Restated Employment Agreement (the “Restated Agreement”) with Dr. Ji. Pursuant to the Restated Agreement, Dr. Henry Ji will continue to serve as our President and Chief Executive Officer for an initial term of three years commencing on May 9, 2017. Following this initial three year term, the Restated Agreement shall renew automatically for additional 12 month terms unless either we or Dr. Ji provide written notice of non-renewal at least three months in advance of the expiration of the then-current term. The Restated Agreement supersedes and replaces a prior employment agreement with Dr. Ji, dated September 21, 2012, as amended on October 18, 2012.

Pursuant to the Restated Agreement, Dr. Ji shall (i) receive an annual base salary (the “Annual Base Salary”) of $600,000, as may be adjusted from time to time; (ii) be eligible to participate in an annual incentive program, with a target annual bonus incentive equal to 55% of his then-current Annual Base Salary (the “Annual Bonus”); and (iii) receive employee benefits, paid personal leave and expense reimbursement in accordance with our policies. In addition, Dr. Ji’s performance will be reviewed by the Board at least annually, and his Annual Base Salary, target Annual Bonus and any other compensation will be subject to adjustment by the Board, provided that Dr. Ji’s Annual Base Salary and target Annual Bonus may not be adjusted downward.

Pursuant to the Restated Agreement, we have the right to terminate Dr. Ji’s employment at any time with or without “cause” (as defined in the Restated Agreement). In addition, Dr. Ji may resign with or without “good reason” (as defined in the Restated Agreement) upon thirty days’ written notice to us. Under each such circumstance, Dr. Ji will be entitled to receive any accrued but unpaid base salary as of the date of termination or resignation, any expenses owed to him and any amount accrued and arising from his participation in, or vested benefits accrued under, any employee benefit plans, programs or arrangements, including any 401(k), profit sharing or pension plan (collectively, the “Termination Payments”).

In the event that Dr. Ji’s employment is terminated by us without “cause” or by our non-renewal of the term of the Restated Agreement, or by Dr. Ji for “good reason,” in either case outside of a Change of Control Window (as defined below), then, subject to Dr. Ji’s timely execution and non-revocation of a release in favor of us, Dr. Ji will be entitled to receive the following: (i) the Termination Payments; (ii) an amount equal to his then-current Annual Base Salary, payable in a lump sum; (iii) an amount equal to his pro-rata then-current target Annual Bonus, payable in a lump sum; (iv) 12 months of health insurance benefits for Dr. Ji and for his eligible dependents who were covered under our health insurance plans as of the date his employment was terminated; and (v) one year of accelerated vesting of Dr. Ji’s then-outstanding awards of equity compensation, with performance-criteria deemed satisfied at target.

If Dr. Ji’s employment is terminated without “cause” or by our non-renewal of the term of the Restated Agreement, or by Dr. Ji for “good reason,” in either case during the period commencing three months prior to a Change of Control and ending 12 months after a Change of Control (as defined in the Restated Agreement) (the “Change of Control Window”), then, subject to Dr. Ji’s timely execution and non-revocation of a release in favor of us, Dr. Ji will be entitled to receive the following: (i) the Termination Payments; (ii) an amount equal to twice his then-current Annual Base Salary, payable in a lump sum; (iii) an amount equal to twice his pro-rata then-current target Annual Bonus, payable in a lump sum; (iv) 24 months of health insurance benefits for Dr. Ji and for his eligible dependents who were covered under our health insurance plans as of the date his employment was terminated; and (v) accelerated vesting of Dr. Ji’s then-outstanding awards of equity compensation, with performance-criteria deemed satisfied target.

In addition, all of his unvested stock options would have immediately vested. If we terminated Mr. Ng for cause or he resigned without good reason, he would not have been entitled to further compensation. He would have had no obligation to seek other employment and any income so earned would not have reduced the foregoing amounts.

POTENTIAL PAYMENTS UPON TERMINATION OR CHANGE IN CONTROL

Other than the provisions of the executive severance benefits to which our named executive officers would be entitled to at December 31, 2018 (the last trading day of the year) as set forth above, we have no liabilities under termination or change in control conditions. We do not have a formal policy to determine executive severance benefits. Each executive severance arrangement is negotiated on an individual basis.

The tables below estimate the current value of amounts payable to our named executive officers in the event that a termination of employment occurred on December 31, 2018 (the last trading day of the year), other than with respect to Mr. Ferrigno, Mr. Ng and Dr. Zeldis as none of the foregoing were serving as an executive officer as of December 31, 2018. The closing price of

our common stock, as reported on the Nasdaq Capital Market, was $2.40 on December 31, 2018. The following tables exclude certain benefits, such as accrued vacation, that are available to all employees generally. The actual amount of payments and benefits that would be provided can only be determined at the time of a change in control and/or the named executive officer’s qualifying separation from the Company.

Item 12.Security Ownership of Certain Beneficial Owners and Management and Related Stockholder Matters.

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

The following table sets forth information as of March 31, 2019, with respect to the beneficial ownership of shares of our common stock by:

• each person or group known to us to be the beneficial owner of more than five percent of our common stock;

16

• each of our directors;

• each of our named executive officers; and

• all of our current directors and executive officers as a group.

This table is based upon information supplied by officers, directors and principal stockholders and a review of Schedules 13D and 13G, if any, filed with the SEC. Other than as set forth below, we are not aware of any other beneficial owner of more than five percent of our common stock as of March 31, 2019. Except as indicated by the footnotes below, we believe, based on the information furnished to us, that the persons and entities named in the table below have sole voting and investment power with respect to all shares of common stock that they beneficially own, subject to applicable community property laws.

Applicable percentage ownership is based on 122,457,257 shares of common stock outstanding as of March 31, 2019, adjusted as required by rules promulgated by the SEC. These rules generally attribute beneficial ownership of securities to persons who possess sole or shared voting power or investment power with respect to those securities. In addition, the rules include shares of common stock issuable pursuant to the exercise of stock options and warrants that are either immediately exercisable or exercisable on or before May 30, 2019, which is 60 days after March 31, 2019. These shares are deemed to be outstanding and beneficially owned by the person holding those options for the purpose of computing the percentage ownership of that person, but they are not treated as outstanding for the purpose of computing the percentage ownership of any other person.

Unless otherwise noted below, the address of each beneficial owner listed in the table is c/o Sorrento Therapeutics, Inc., 4955 Directors Place, San Diego, California 92121.

Semnur Pharmaceuticals, Inc. Acquisition

On March 18, 2019, we, for limited purposes, entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Semnur Pharmaceuticals, Inc., a Delaware corporation (“Semnur”), Scilex Holding Company, a Delaware corporation (“HoldCo”), Sigma Merger Sub, Inc., a Delaware corporation and wholly owned subsidiary of HoldCo (“Merger Sub”), and Fortis Advisors LLC, solely as representative of the holders of Semnur equity (the “Equityholders’ Representative”). Pursuant to the Merger Agreement, Merger Sub merged with and into Semnur (the “Merger”), with Semnur surviving as a wholly owned subsidiary of HoldCo.

Concurrently with the execution of the Merger Agreement, we and each of the other holders of outstanding shares of capital stock of Scilex Pharmaceuticals Inc., a Delaware corporation and our majority-owned subsidiary (“Scilex”), contributed each share of Scilex capital stock we or it owned to HoldCo in exchange for one share of HoldCo common stock (the “Contribution”). As a result of the Contribution, and prior to the consummation of the Merger, Scilex became a wholly-owned subsidiary of HoldCo and we became the owner of approximately 77% of HoldCo’s issued and outstanding capital stock.

Pursuant to the Merger Agreement, and upon the terms and subject to the conditions contained therein, following the closing of the Merger (the “Closing”), HoldCo is required to pay to the holders of Semnur’s capital stock and options to purchase Semnur’s common stock (collectively, the “Semnur Equityholders”) upfront consideration with a value of approximately $70.0 million plus the aggregate exercise price of outstanding options to purchase Semnur’s common stock (which amount will be subsequently deducted from the amounts otherwise payable to the holders of such options), consisting of the following: (a) a cash payment of approximately $12.4 million, and (b) 47,392,287 shares of HoldCo common stock (the “Stock Consideration”). A portion of the cash consideration otherwise payable to the Semnur Equityholders was set aside for expenses incurred by the Equityholders’ Representative, and 4,749,095 shares of HoldCo common stock otherwise issuable to Semnur Equityholders were placed in escrow with a third party as security for the indemnification obligations of the Semnur Equityholders under the Merger Agreement, including in respect of breaches of representations and warranties of Semnur included in the Merger Agreement. The Semnur Equityholders that receive the Stock Consideration are required to sign an exchange and registration rights agreement with us (the “Exchange Agreement”), which is further described below.

Following the issuance of the Stock Consideration, we are the owner of approximately 58% of HoldCo’s issued and outstanding capital stock. Pursuant to the Merger Agreement, and upon the terms and subject to the conditions contained therein, HoldCo has also agreed to pay the Semnur Equityholders up to $280.0 million in aggregate contingent cash

21

consideration based on the achievement of certain milestones, including obtaining the first approval of a New Drug Application of a Semnur product by the U.S. Food and Drug Administration and the achievement of certain amounts of net sales of Semnur products.

Pursuant to the Exchange Agreement, and upon the terms and subject to the conditions contained therein, if within 18 months following the Closing, 100% of the outstanding equity of HoldCo has not been acquired by a third party and HoldCo has not entered into a definitive agreement with respect to, or otherwise consummated, a firmly underwritten offering of HoldCo capital stock on a major stock exchange that meets certain requirements and includes the Stock Consideration, then holders of the Stock Consideration may collectively elect to exchange, during the 60-day period commencing the date that is the 18 month anniversary of the Closing (the “Share Exchange”), the Stock Consideration for shares of our common stock with a value of $55.0 million based on a price per share of our common stock equal to the greater of (a) the 30-day trailing volume weighted average price of one share of our common stock as reported on Nasdaq as of the consummation of the Share Exchange and (b) $5.55 (subject to adjustment for any stock dividend, stock split, stock combination, reclassification or similar transaction).

Pursuant to the terms of the Exchange Agreement, and subject to the limitations contained therein, within 30 days following consummation of the Share Exchange (if it occurs at all), we have agreed to prepare and file with the Securities and Exchange Commission a registration statement to enable the public resale on a delayed or continuous basis of the shares of our common stock issued in the Share Exchange (the “Registration Statement”) and use its commercially reasonable efforts to maintain the effectiveness of such Registration Statement for up to three years thereafter. In the Exchange Agreement, we have also agreed to indemnify the applicable Semnur Equityholders and their affiliates for certain liabilities related to such Registration Statement, including certain liabilities arising under the Securities Act of 1933, as amended, and the Securities Exchange Act of 1934, as amended.

Mr. Shah, a member of our Board of Directors, was Semnur’s Chief Executive Officer, a member of its Board of Directors and a stockholder of Semnur prior to the acquisition transaction.

Scilex Pharmaceuticals Inc. Acquisition

On November 8, 2016, we entered into a Stock Purchase Agreement (the “Stock Purchase Agreement”) with Scilex and a majority of the stockholders of Scilex (the “Scilex Stockholders”) pursuant to which we acquired from the Scilex Stockholders approximately 72% of the outstanding capital stock of Scilex. Dr. Henry Ji, our President and Chief Executive Officer and a member of our Board of Directors, and George K. Ng, our former Vice President, Chief Administrative Officer and Chief Legal Officer, were stockholders of Scilex prior to the acquisition transaction.

At the closing of the Scilex acquisition, we issued to the Scilex Stockholders consideration valued at $4.8 million, which consisted primarily of an aggregate of 754,911 shares of our common stock.

On September 11, 2017, we received notice from the FDA that the FDA had accepted Scilex’s resubmitted new drug application for ZTlido® for the treatment of postherpetic neuralgia and we issued to certain of the Scilex Stockholders consideration valued at $1.4 million, which consisted primarily of an aggregate of 754,930 shares of our common stock.

On February 28, 2018, the FDA approved ZTlido® (lidocaine topical system 1.8%) for the relief of pain associated with post-herpetic neuralgia. Scilex is currently in preparations for a commercial launch of ZTlido® (lidocaine topical system 1.8%) and exploring potential partnerships for the product. As a result of the FDA approval, pursuant to the Stock Purchase Agreement, we became obligated to deliver to certain of the Scilex Stockholders cash and shares of common stock with a total value of approximately $38.2 million. In satisfaction of this obligation, we issued 1,381,346 shares of common stock to the Scilex Stockholders and paid the Scilex Stockholders an aggregate of $24.5 million in cash.

Indemnification Agreements with Directors and Executive Officers

We have entered into indemnity agreements with certain directors, officers and other key employees of ours under which we agreed to indemnify those individuals under the circumstances and to the extent provided for in the agreements, for expenses, damages, judgments, fines, settlements and any other amounts they may be required to pay in actions, suits or proceedings which they are or may be made a party or threatened to be made a party by reason of their position as a director, officer or other agent of ours, and otherwise to the fullest extent permitted under Delaware law and our Bylaws. We also have an insurance policy covering our directors and executive officers with respect to certain liabilities, including liabilities arising under the Securities Act of 1933, as amended, or otherwise. We believe that these provisions and insurance coverage are necessary to attract and retain qualified directors, officers and other key employees.

Board Independence

Our Board is responsible for establishing corporate policies and for our overall performance, although it is not involved in our day-to-day operations. Our Board consults with our counsel to ensure that our Board’s determinations are consistent with all relevant securities and other laws and regulations regarding the definition of “independent,” including those set forth in the rules of The Nasdaq Stock Market LLC, as in effect from time to time. Consistent with these considerations, after review of all relevant transactions or relationships between each director, or any of his or her family members, us, our senior management and our independent registered public accounting firm, our Board has determined that all of our directors, other than Dr. Ji and Mr. Shah, are independent.

Item 14.Principal Accounting Fees and Services.

Independent Registered Public Accounting Firm’s Fees

The following table represents aggregate fees billed to us for the fiscal years ended December 31, 2018 and December 31, 2017 by Deloitte & Touche LLP, our independent registered public accounting firm for such period. All fees described below were pre-approved by the Audit Committee.

	Year Ended December 31
	2018		2017
Audit Fees (1)	$	2,213,739	$	1,394,391
Audit-Related Fees	—		—
Tax Fees (2)	827,152		409,971
All Other Fees	—		—
Total Fees	$	3,040,891	$	1,804,362

(1) Audit fees consisted of fees for services rendered in connection with the annual audit of our consolidated financial statements, quarterly reviews of financial statements included in our quarterly reports on Form 10-Q, and the audit of internal control over financial reporting. Audit fees also consisted of services provided in connection with issuances of consents included in registration statements, standalone audits, consultation on accounting matters, and SEC registration statement services.

(2) Tax services consisted of fees for tax consultation and tax compliance services.

Audit Committee’s Pre-Approval Policies and Procedures

The Audit Committee has adopted a policy for the pre-approval of audit and non-audit services rendered by our independent registered public accounting firm. The policy generally pre-approves specified services in the defined categories of audit services, audit-related services and tax services up to specified amounts. Pre-approval may also be given as part of the Audit Committee’s approval of the scope of the engagement of the independent auditors or on an individual explicit case-by-case basis before the independent registered public accounting firm are engaged to provide each service. The pre-approval of services may be delegated to one or more of the Audit Committee members, but the decision must be reported to the full Audit Committee at its next scheduled meeting. By the adoption of this policy, the Audit Committee has delegated the authority to pre-approve services to the Chairperson of the Audit Committee, subject to certain limitations.

The Audit Committee has determined that the rendering of services by Deloitte & Touche LLP other than audit services is compatible with maintaining the principal accounting firm’s independence.
