You should read the following discussion and analysis of our financial condition and results of operations together with our financial statements and related notes appearing elsewhere in this Annual Report on Form 10-K. In addition to historical information, this discussion and analysis contains forward-looking statements that involve risks, uncertainties and assumptions. Our actual results may differ materially from those anticipated in these forward-looking statements as a result of certain factors. We discuss factors that we believe could cause or contribute to these differences below and elsewhere in this report, including those set forth under Item 1A. "Risk Factors" and under "Cautionary Note Regarding Forward-Looking Statements" in this Annual Report.

Overview

We are a biopharmaceutical company developing novel therapies designed to treat patients with cancer by inhibiting fundamental tumor-promoting pathways and by harnessing the immune system to attack cancer cells. Our strategy is to identify, acquire, and develop molecules that will rapidly translate into high impact therapeutics that generate durable clinical benefit and enhanced patient outcomes. Our two clinical stage programs are:



        º •
        º DKN-01: A monoclonal antibody that inhibits Dickkopf-related protein
          1, or DKK1. DKK1 is a protein that regulates the Wnt signaling
          pathways and enables tumor cells to profilerate and spread, as well as
          suppresses the immune system from attacking the tumor. When DKN-01
          binds to DKK1, an anti-tumor effect can be generated. DKN-01-based
          therapies have generated responses and clinical benefit in several
          patient populations. We are currently studying DKN-01 in multiple
          ongoing clinical trials in patients with esophagogastric cancer,
          hepatobiliary cancer, gynecologic cancers, or prostate cancer. In
          January 2020, we entered into an Option and License Agreement with
          BeiGene, Ltd., or BeiGene, which granted BeiGene the right to develop
          and commercialize DKN-01 in Asia (excluding Japan), Australia, and New
          Zealand.

        º •
        º TRX518: A monoclonal antibody targeting the glucocorticoid-induced
          tumor necrosis factor-related receptor, or GITR. GITR is a receptor
          found on the surface of a wide range of immune cells. GITR stimulation
          activates tumor fighting white blood cells and decrease the activity
          of potentially tumor-protective immunosuppressive cells. TRX518 has
          been specifically engineered to enhance the immune system's anti-tumor
          response by activating GITR signaling without causing the immune cells
          to be destroyed. We conducted clinical trials of TRX518 in patients
          with advanced solid tumors in combination with gemcitabine
          chemotherapy or with cancer immunotherapies known as PD-1 antagonists.
          In November 2019, we announced that we have deprioritized continued
          development of TRX518.

We intend to apply our extensive experience identifying and developing transformational products to aggressively develop these antibodies and build a pipeline of programs that has the potential to change the practice of cancer medicine.

We have devoted substantially all of our resources to development efforts relating to our product candidates, including manufacturing and conducting clinical trials of our product candidates, providing general and administrative support for these operations and protecting our intellectual property. We do not have any products approved for sale and have not generated any revenue from product sales. We have funded our operations primarily through proceeds from our sales of common stock and preferred stock and proceeds from the issuance of notes payable-related party.

We have incurred net losses in each year since our inception in 2011. Our net loss was $32.9 million for the year ended December 31, 2019 and $23.1 million for the year ended December 31, 2018. As of December 31, 2019, we had an accumulated deficit of approximately $195.2 million. Our net losses have resulted primarily from costs incurred in connection with our research and development programs and from general and administrative costs associated with our operations. We expect to continue to incur significant expenses and have operating losses for at least the next several years as we:



        º •
        º continue the development of our product candidate, DKN-01;

        º •
        º seek to obtain regulatory approvals for DKN-01;

        º •
        º outsource the manufacturing of DKN-01 for clinical trials and any
          indications for which we receive regulatory approval;

        º •
        º contract with third parties for the sales, marketing and distribution
          of DKN-01 for any indications for which we receive regulatory
          approval;

        º •
        º maintain, expand and protect our intellectual property portfolio;

        º •
        º continue our research and development efforts;

        º •
        º add operational, financial and management information systems and
          personnel, including personnel to support our product development
          efforts; and

        º •
        º operate as a public company.

We do not expect to generate revenue from product sales unless and until we successfully complete development and obtain marketing approval for one or more of our product candidates, which we expect will take a number of years and is subject to significant uncertainty. Accordingly, we will need to raise additional capital prior to the commercialization of DKN-01 or any other product candidate. Until such time, if ever, as we can generate substantial revenue from product sales, we expect to finance our operating activities through a combination of equity offerings, debt financings, government or other third-party funding, commercialization, marketing and distribution arrangements and other collaborations, strategic alliances and licensing arrangements, such as the BeiGene Agreement. However, we may be unable to raise additional funds or enter into such other arrangements when



                                       68

needed on favorable terms or at all. Our failure to raise capital or enter into such other arrangements as and when needed would have a negative impact on our financial condition and our ability to develop our product candidates.

BeiGene License Agreement

On January 3, 2020, we entered into an exclusive option and license agreement (the "BeiGene Agreement") with BeiGene, Ltd. ("BeiGene") for the clinical development and commercialization of DKN-01, our anti-Dickkopf-1 (DKK1) antibody, in Asia (excluding Japan), Australia, and New Zealand. We retain exclusive rights for the development, manufacturing, and commercialization of DKN-01 for the rest of the world.

Pursuant to the BeiGene Agreement, we received an upfront cash payment of $3.0 million from BeiGene in exchange for granting BeiGene an option to an exclusive license to develop and commercialize DKN-01 in Asia (excluding Japan), Australia, and New Zealand, and will be eligible to receive an additional payment upon BeiGene's exercise of the option. Additionally, we are eligible to receive payments of up to $132.0 million based upon the achievement of certain development, regulatory, and sales milestones as well as tiered royalties on any product sales of DKN-01 in the licensed territory.

Private Placement-January 2020

On January 3, 2020, we entered into a Securities Purchase Agreement (the "Securities Purchase Agreement") with institutional investors named therein (collectively, the "Purchasers," and each, a "Purchaser"), providing for a private placement transaction exempt from the registration requirements of the Securities Act of 1933, as amended (the "Securities Act"), pursuant to which we issued and sold 1,421,801 shares of our Series A Mandatorily Convertible Cumulative Non-Voting Perpetual Preferred Stock, par value $0.001 per share (the "Series A Preferred Stock"), at a purchase price of $10.54 per share, and 1,137,442 shares of our Series B Mandatorily Convertible Cumulative Non-Voting Perpetual Preferred Stock, par value $0.001 per share (the "Series B Preferred Stock") at a purchase price of $10.55 per share, and one (1) share of our Special Voting Stock, par value $0.001 (the "Special Voting Stock") entitling the Purchaser of Series A Preferred Stock to elect one member of our Board of Directors for aggregate net proceeds to us of approximately $25.3 million (the "Transaction"). On March 5, 2020, our stockholders approved the conversion of the Series A preferred stock into a pre-funded warrant to purchase 14,413,902 shares of common stock and the conversion of the Series B preferred stock into 11,531,133 shares of common stock. Each investor also received a warrant to purchase an equal number of shares at an exercise price of $2.11 per share.

As of December 31, 2019, we had cash and cash equivalents of $3.9 million. We believe that our cash and cash equivalents as of December 31, 2019, together with the $25.3 million in net proceeds from the January 2020 private placement and the $3.0 million upfront cash payment received from BeiGene, will enable us to fund our operating expenses and capital expenditure requirements for at least 12 months from issuance of the financial statements included in this Annual Report on Form 10-K. See "-Liquidity and Capital Resources."

Financial Overview

Research and Development Expenses

Our research and development activities have included conducting nonclinical studies and clinical trials, manufacturing development efforts and activities related to regulatory filings for DKN-01 and



                                       69

Table of Contents

TRX518. We recognize research and development expenses as they are incurred. Our research and development expenses consist primarily of:



        º •
        º salaries and related overhead expenses for personnel in research and
          development functions, including costs related to stock-based
          compensation;

        º •
        º fees paid to consultants and CROs for our nonclinical and clinical
          trials, and other related clinical trial fees, including but not
          limited to laboratory work, clinical trial database management,
          clinical trial material management and statistical compilation and
          analysis;

        º •
        º costs related to acquiring and manufacturing clinical trial materials;
          and

        º •
        º costs related to compliance with regulatory requirements.

We plan to increase our research and development expenses for the foreseeable future as we continue the development of DKN-01 and any other product candidates, subject to the availability of additional funding.

Our direct research and development expenses are tracked on a program-by-program basis and consist primarily of internal and external costs, such as employee costs, including salaries and stock-based compensation, other internal costs, fees paid to consultants, central laboratories, contractors and CROs in connection with our clinical and preclinical trial development activities. We use internal resources to manage our clinical and preclinical trial development activities and perform data analysis for such activities.

We participate, through our subsidiary in Australia, in the Australian government's R&D Incentive program, such that a percentage of our eligible research and development expenses are reimbursed by the Australian government as a refundable tax offset and such incentives are reflected as other income. The percentage was 43.5% for both the years ended December 31, 2019 and 2018.



    The table below summarizes our research and development expenses incurred by
development program and the R&D incentive income for the years ended
December 31, 2019 and 2018:

                                                             Year Ended
                                                            December 31,

        Direct research and development by program:
        DKN-01 program                                   $ 16,130   $ 15,624
        TRX518 program                                      8,236      6,206

        Total research and development expenses          $ 24,366   $ 21,830



        Australian research and development incentives   $    132   $    756

The successful development of our clinical product candidates is highly uncertain. At this time, we cannot reasonably estimate the nature, timing or costs of the efforts that will be necessary to complete the remainder of the development of any of our product candidates or the period, if any, in which material net cash inflows from these product candidates may commence. This is due to the numerous risks and uncertainties associated with developing drugs, including the uncertainty of:



        º •
        º the scope, rate of progress and expense of our ongoing, as well as any
          additional, clinical trials and other research and development
          activities;

        º •
        º future clinical trial results; and

        º •
        º the timing and receipt of any regulatory approvals.

                                       70

--------------------------------------------------------------------------------

Table of Contents

A change in the outcome of any of these variables with respect to the development of a product candidate could result in a significant change in the costs and timing associated with the development of that product candidate. For example, if the FDA or another regulatory authority were to require us to conduct clinical trials beyond those that we currently anticipate will be required for the completion of clinical development of a product candidate, or if we experience significant delays in enrollment in any of our clinical trials, we could be required to expend significant additional financial resources and time on the completion of clinical development.

General and Administrative Expenses

General and administrative expenses consist primarily of salaries and related costs, including stock-based compensation, for personnel in executive, finance and administrative functions. General and administrative expenses also include direct and allocated facility-related costs as well as professional fees for legal, patent, consulting, accounting and audit services.

We anticipate that our general and administrative expenses will increase in the future as we increase our headcount to support our continued research activities and development of our product candidates. We also anticipate that we will incur increased accounting, audit, legal, regulatory, compliance, director and officer insurance costs as well as investor and public relations expenses associated with being a public company.

Interest income

Interest income consists primarily of interest income earned on cash and cash equivalents. During the years ended December 31, 2019 and 2018, interest income was $0.3 million and $0.4 million, respectively.

Research and development incentive income

Research and development incentive income includes payments under the R&D Incentive program from the government of Australia. The R&D Incentive is one of the key elements of the Australian Government's support for Australia's innovation system. It was developed to assist businesses to recover some of the costs of undertaking research and development. The research and development tax incentive provides a tax offset to eligible companies that engage in research and development activities.



    Companies engaged in research and development may be eligible for either:

        º •
        º a 43.5% refundable tax offset for entities with an aggregated turnover
          of less than A$20 million per annum, or

        º •
        º a 38.5% non-refundable tax offset for all other entities.

We recognize as other income the amount we expect to be reimbursed for qualified expenses.

Foreign currency translation adjustment

Foreign currency translation adjustment consists of gains (losses) due to the revaluation of foreign currency transactions attributable to changes in foreign currency exchange rates associated with our Australian subsidiary.

Income taxes

Since our inception, we have not recorded any U.S. federal, state or foreign income tax benefits for the net losses we have incurred in each year, due to our uncertainty of realizing a benefit from those items. As of December 31, 2019, we had federal, state and foreign net operating loss carryforwards of $135.9 million, $117.6 million and $83.9 million, respectively. The federal and state net operating losses begin to expire in 2030, while the foreign net operating losses carryforward indefinitely.



                                       71

--------------------------------------------------------------------------------

Table of Contents

Our federal net operating losses include $54.6 million which can be also carried forward indefinitely. We may be able to utilize our net operating loss carryforwards to reduce future federal and state income tax liabilities. However, these net operating losses are subject to various limitations under Internal Revenue Code ("IRC") Section 382, which limits the use of net operating loss carryforwards to the extent there has been an ownership change of more than 50 percentage points. In addition, the net operating loss carryforwards are subject to examination by the taxing authorities and could be adjusted or disallowed due to such exams. Although we have not undergone an IRC Section 382 analysis, it is possible that the utilization of our net operating loss carryforwards may be limited.

As of December 31, 2019, we also had federal and state research and development tax credit carryforwards of $3.8 million and $0.6 million, respectively, which begin to expire in 2030 and whose future usage may also be limited to the extent there has been an ownership change of more than 50 percentage points.

There is no provision for income taxes in the United States or Israel, because we have historically incurred operating losses and maintain a full valuation allowance against our deferred tax assets in these jurisdictions. The deferred tax asset recorded in the consolidated balance sheets relates to our Australian operations.

Critical Accounting Policies and Significant Judgments and Estimates

Our management's discussion and analysis of our financial condition and results of operations is based on our consolidated financial statements, which we have prepared in accordance with U.S. Generally Accepted Accounting Principles ("GAAP"). The preparation of these consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements, as well as the reported expenses during the reporting periods. We evaluate these estimates and judgments on an ongoing basis. We base our estimates on historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Our actual results may differ from these estimates under different assumptions or conditions.

While our significant accounting policies are more fully described in Note 2 to our consolidated financial statements appearing elsewhere in this report, we believe that the following accounting policies are the most critical for fully understanding and evaluating our financial condition and results of operations.

Accrued Research and Development Expenses

As part of the process of preparing consolidated financial statements, we are required to estimate accrued research and development expenses. This process involves communicating with our applicable personnel to identify services that have been performed on our behalf and estimating the level of service performed and the associated cost incurred for the service when we have not yet been invoiced or otherwise notified of actual cost. The majority of our service providers invoice us monthly for services performed. We make estimates of our accrued research and development expenses as of each balance sheet date in our consolidated financial statements based on facts and circumstances known to us. We periodically confirm the accuracy of our estimates with selected service providers and make adjustments, if necessary. To date, we have not adjusted our estimate at any particular balance sheet date by any material amount. Examples of estimated accrued research and development expenses include:



        º •
        º fees paid to CROs for management of our clinical trial activities;

        º •
        º fees paid to investigative sites in connection with clinical trials;

        º •
        º fees paid to contract manufacturers in connection with the production
          of clinical trial supplies; and

        º •
        º professional services and fees.

                                       72

--------------------------------------------------------------------------------

Table of Contents

We base our expenses related to clinical trials on our estimates of the services received and efforts expended pursuant to contracts with multiple research institutions and CROs that conduct and manage clinical trials on our behalf. The financial terms of these agreements are subject to negotiation, vary from contract to contract and may result in uneven payment flows. Payments under some of these contracts depend on factors such as the successful enrollment of patients and the completion of clinical trial milestones. In accruing service fees, we estimate the time period over which services will be performed and the level of effort to be expended in each period. If we do not accurately identify costs that we have begun to incur or if we underestimate or overestimate the level of services performed or the costs of these services, our actual expenses could differ from our estimates.

Stock-Based Compensation

We have issued options to purchase our common stock. We account for stock based compensation in accordance with ASC 718, Compensation-Stock Compensation. ASC 718 establishes accounting for stock-based awards exchanged for employee services. Under the fair value recognition provisions of ASC 718, stock-based compensation cost is measured at the grant date based on the fair value of the award and is recognized as expense over the requisite service or vesting period. Determining the appropriate fair value model and calculating the fair value of stock-based payment awards require the use of highly subjective assumptions, including the expected life of the stock-based payment awards and stock price volatility.

We estimate the grant date fair value of stock options and the related compensation expense, using the Black-Scholes option valuation model. This option valuation model requires the input of subjective assumptions including: (1) expected life (estimated period of time outstanding) of the options granted, (2) volatility, (3) risk-free rate and (4) dividends. In general, the assumptions used in calculating the fair value of stock-based payment awards represent management's best estimates, but the estimates involve inherent uncertainties and the application of management judgment. As a result, if factors change and we use different assumptions, our stock-based compensation expense could be materially different in the future.

JOBS Act

We are an "emerging growth company", or EGC, as defined in the Jumpstart Our Business Startups Act of 2012 (the "JOBS Act"). The JOBS Act, permits an "emerging growth company" such as us to take advantage of an extended transition period to comply with new or revised accounting standards applicable to public companies until those standards would otherwise apply to private companies. We may elect to use the extended transition period for complying with new or revised accounting standards under Section 102(b)(1) of the JOBS Act. This election would allow us to delay the adoption of new or revised accounting standards that have different effective dates for public and private companies until those standards apply to private companies. As a result of this election, our financial statements may not be comparable to companies that comply with public company effective dates.

We may take advantage of these reporting exemptions until we are no longer an emerging growth company, which in certain circumstances could be for up to five years. We will remain an "emerging growth company" until the earliest of (a) the last day of the first fiscal year in which our annual gross revenues exceed $1.07 billion, (b) the date that we become a "large accelerated filer" as defined in Rule 12b-2 under the Securities Exchange Act of 1934, as amended, or the Exchange Act, which would occur if the market value of our shares that are held by non-affiliates exceeds $700 million as of the last business day of our most recently completed second fiscal quarter, (c) the date on which we have issued more than $1.0 billion in nonconvertible debt during the preceding three-year period and (d) the last day of our 2022 fiscal year containing the fifth anniversary of the date on which shares of our common stock became publicly traded in the U.S. As of December 31, 2019, we remain an EGC.

Research and development expenses were $24.4 million for the year ended December 31, 2019, compared to $21.8 million for the year ended December 31, 2018. The increase of $2.6 million was primarily due to a $3.5 million increase in clinical trial costs due to an increase in patient enrollment, a $0.7 million increase in payroll and other related expenses due to an increase in headcount in our full time research and development employees and a $0.3 million increase in stock based compensation expense due to new stock options and restricted stock units granted to employees during the year ended December 31, 2019. These increases were partially offset by a $1.5 million decrease in manufacturing costs related to clinical trial material due to timing of manufacturing campaigns and a $0.5 million decrease in consulting fees associated with research and development activities during the year ended December 31, 2019 as compared to the year ended December 31, 2018.

General and Administrative Expenses

General and administrative expenses were $9.1 million for the year ended December 31, 2019, compared to $8.9 million for the year ended December 31, 2018. The increase of $0.2 million was due

to a $0.3 million increase in stock based compensation expense due to new stock options and restricted stock units granted to employees during the year ended December 31, 2019. This increase was partially offset by a $0.1 million decrease in payroll and other related expenses.

Interest Income

We recorded interest income of $0.3 million and $0.4 million, respectively, for the years ended December 31, 2019 and 2018. The decrease in interest income is primarily due to a higher average cash balance during the year ended December 31, 2018 as compared to 2019.

Australian Research and Development Incentives

We recorded R&D incentive income of $0.1 million and $0.8 million for the years ended December 31, 2019 and 2018, respectively, based upon the applicable percentage of eligible research and development activities under the Australian Incentive Program, net of our Australia tax liability, which expenses included the cost of manufacturing of clinical trial material.

We perform certain supporting research and development activity outside of Australia when there are no Australian facilities that support the activity ("Overseas research and development activities"). In October 2017, the Commonwealth of Australia issued us a favorable ruling on our Overseas research and development activities, considering such activities to be eligible research and development activities under the Australian Incentive Program.

During the year ended December 31, 2019, we received $0.8 million of research and development tax incentive payments from the Commonwealth of Australia as a result of the 2018 research and development activities. During the year ended December 31, 2018, we received $0.8 million of research and development tax incentive payments from the Commonwealth of Australia as a result of the 2017 research and development activities.

The remaining R&D incentive receivable has been recorded as "Research and development incentive receivable" in the consolidated balance sheets.

Foreign Currency Gains (Loss)

We recorded foreign currency gains (losses) of 0.1 million and ($0.8) million, respectively, for the years ended December 31, 2019 and 2018. The increase in foreign currency gains is due to the changes in the Australian dollar exchange rate related to activities of the Australian entity.

Interest Expense

We recorded an immaterial amount of interest expense for the years ended December 31, 2019 and 2018.

Liquidity and Capital Resources

Since our inception, we have incurred significant operating losses. We have not yet commercialized any of our product candidates, which are in various phases of clinical trials, and we do not expect to generate revenue from sales of any product for several years, if at all. We have funded our operations to date with proceeds from the sale of common stock and preferred stock and notes payable-related party.

As of December 31, 2019, we had cash and cash equivalents of $3.9 million. In January 2020, we issued common stock in a private placement for aggregate net proceeds of $25.3 million and we entered into an exclusive option and license agreement with BeiGene which included a $3.0 million upfront cash payment.

We expect that our cash and cash equivalents of $3.9 million at December 31, 2019, together with the $25.3 million in aggregate net proceeds from the January 2020 private placement and the $3.0 million upfront cash payment received from BeiGene, will be sufficient to fund our operating expenses for at least the next 12 months from issuance of the financial statements included in this Annual Report on Form 10-K. In addition, we will seek additional funding through public or private equity financings or government programs and will seek funding or development program cost-sharing through collaboration agreements or licenses with larger pharmaceutical or biotechnology companies. If we do not obtain additional funding or development program cost-sharing, we would be forced to delay, reduce or eliminate certain clinical trials or research and development programs, reduce or eliminate discretionary operating expenses, and delay company and pipeline expansion, which would adversely affect our business prospects. The inability to obtain funding, as and when needed, would have a negative impact on Leap's financial condition and our ability to pursue our business strategies.

Cash Flows



    The following table summarizes our sources and uses of cash for each of the
periods presented:

Net decrease in cash and cash equivalents                 $     (12,393 )  $   (9,453 )

Operating activities. Net cash used in operating activities for the year ended December 31, 2019 was primarily related to our net loss from the operation of our business of $32.9 million and net changes in working capital, including a decrease in lease liabilities of $0.7 million. These changes were partially offset by an increase in accounts payable and accrued expenses of $1.1 million, a decrease of $0.6 million in research and development receivable, a decrease of $0.3 million in prepaid expenses and other assets, noncash stock based compensation expense of $3.7 million and change in restricted stock liability of $0.2 million.

Net cash used in operating activities for the year ended December 31, 2018 was primarily related to our net loss from the operation of our business of $23.1 million and net changes in working capital, including an increase in prepaid expenses and other assets of $0.3 million and a noncash change in the fair value of the warrant liability of $7.3 million, partially offset by noncash stock based compensation expense of $3.5 million, an increase of $0.8 million in research and development incentive receivable and an increase in accounts payable and accrued expenses of $0.4 million. The increase in accounts payable and accrued expenses was due to timing of vendor invoicing and payments.

Investing Activities. Net cash used in investing activities during the year ended December 31, 2019 was related to purchases of equipment. There were no investing activities during the year ended December 31, 2018.

Financing Activities. Net cash provided by financing activities for the year ended December 31, 2019 consisted of $12.3 million in proceeds from the issuance of common stock in connection with the 2019 Public Offering, net of underwriter commissions and discounts, $1.9 million in proceeds from the issuance of common stock under our Distribution Agreement with Raymond James & Associates, Inc. and $1.0 million in proceeds from the issuance of common stock under the Distribution Agreement

with Lincoln Park Capital. These increases were partially offset by payments of $0.4 million for deferred offering costs.

Net cash provided by financing activities for the year ended December 31, 2018 consisted of $15.0 million in proceeds from the issuance of common stock in connection with the March 2018 public offering, net of underwriter commissions and discounts, and $1.2 million in proceeds from the exercise of common stock warrants, partially offset by payments of $0.3 million for deferred offering costs.

Capital Requirements

We expect our expenses to increase substantially in connection with our ongoing activities, particularly as we advance the preclinical activities and clinical trials of our product candidates in development. In addition, we expect to incur additional costs associated with operating as a public company.



    Our expenses will also increase as we:

        º •
        º pursue the clinical development of our most advanced product
          candidate, DKN-01;

        º •
        º seek to identify and develop additional product candidates;

        º •
        º maintain, expand and protect our intellectual property portfolio;

        º •
        º expand our operational, financial and management systems and increase
          personnel, including personnel to support our clinical development,
          manufacturing and commercialization efforts and our operations as a
          public company; and

        º •
        º increase our product liability and clinical trial insurance coverage
          as we initiate our clinical trials and commercialization efforts.

Additional funding may not be available at the time needed on commercially reasonable terms, if at all.
