Notes to Unaudited Condensed Consolidated Financial Statements

1. Basis of Presentation

We are a Delaware corporation, originally incorporated in 1988 under the name Terrapin Diagnostics, Inc. in the State of Delaware, and subsequently renamed “Telik, Inc.” in 1998, and thereafter renamed MabVax Therapeutics Holdings, Inc. (“MabVax Therapeutics Holdings”) in September 2014. Our principal corporate office is located at 11535 Sorrento Valley Road, Suite 400, San Diego, CA 92121 telephone: (858) 259-9405. On July 8, 2014, we consummated a merger with MabVax Therapeutics, Inc. (“MabVax Therapeutics”), pursuant to which our subsidiary Tacoma Acquisition Corp. merged with and into MabVax Therapeutics, with MabVax Therapeutics surviving as our wholly owned subsidiary. This transaction is referred to as the “Merger.” Unless the context otherwise requires, references to “we,” “our,” “us,” or the “Company” in this Quarterly Report mean MabVax Therapeutics Holdings on a condensed consolidated financial statement basis with our wholly-owned subsidiary following the Merger, MabVax Therapeutics, as applicable. The Company has traded under the symbol MBVX (OTCQB: MBVX) since October 10, 2014.

The balance sheet data at December 31, 2015, has been derived from audited financial statements at that date. It does not include, however, all of the information and notes required by accounting principles generally accepted in the United States of America (“GAAP”) for complete financial statements.

The Company is a clinical stage biopharmaceutical company engaged in the discovery, development and commercialization of proprietary human monoclonal antibody products and vaccines for the treatment of a variety of cancers. The Company has discovered a pipeline of human monoclonal antibody products based on the protective immune responses generated by patients who have been immunized against targeted cancers. Therapeutic vaccines under development were discovered at Memorial Sloan Kettering Cancer Center (“MSK”) and are exclusively licensed to MabVax Therapeutics. The Company operates in only one business segment.

The Company has incurred net losses since inception and expects to incur substantial losses for the foreseeable future as it continues its research and development activities. To date, the Company has funded operations primarily through government grants, proceeds from the sale of common and preferred stock, the issuance of debt, the issuance of common stock in lieu of cash for services, payments from collaborators, and interest income. The process of developing products will require significant additional research and development, preclinical testing and clinical trials, as well as regulatory approvals. We expect these activities, together with general and administrative expenses, to result in substantial operating losses for the foreseeable future. The Company will not receive substantial revenue unless we or our collaborative partners complete clinical trials, obtain regulatory approvals and successfully commercialize one or more products; or we license our technology after achieving one or more milestones of interest to a potential partner.

The accompanying unaudited condensed consolidated financial statements were prepared using GAAP for interim financial information and the instructions to Regulation S-X. While these statements reflect all normal recurring adjustments which are, in the opinion of management, necessary for a fair presentation of the results of the interim period, they do not include all information or notes required by GAAP for annual financial statements and should be read in conjunction with the Audited Financial Statements of MabVax Therapeutics Holdings for the year ended December 31, 2015, filed in our Annual Report on Form 10-K on March 14, 2016.

The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of expenses during the reporting period. Management believes that these estimates are reasonable; however, actual results may differ from these estimates.

Recent Accounting Pronouncements

In February 2016, the FASB issued ASU 2016-2,"Leases (Topic 842)". This update will increase transparency and comparability by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. Under the new guidance, lessees will be required to recognize the following for all leases (with the exception of short-term leases) at the commencement date (i) a lease liability, which is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis; and (ii) a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. Under the new guidance, lessor accounting is largely unchanged, and it simplified the accounting for sale and leaseback transactions. Lessees will no longer be provided with a source of off-balance sheet financing. Lessees (for capital and operating leases) and lessors (for sales-type, direct financing, and operating leases) must apply a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. The modified retrospective approach would not require any transition accounting for leases that expired before the earliest comparative period presented. Lessees and lessors may not apply a full retrospective transition approach. The standard is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. We are currently in the process of assessing what impact this new standard may have on our condensed consolidated financial statements.

Management does not believe that any other recently issued, but not yet effective, accounting standards if currently adopted would have a material effect on the accompanying condensed consolidated financial statements.

2. Liquidity and Going Concern

The accompanying condensed consolidated financial statements have been prepared on the going concern basis, which assumes that the Company will continue to operate as a going concern and which contemplates the realization of assets and the satisfaction of liabilities and commitments in the normal course of business. As reflected in the accompanying condensed consolidated financial statements, the Company had a net loss of $4,404,770, net cash used in operating activities of $2,911,630, net cash used in investing activities of $153,899, and net cash provided by financing activities of $4,610,324 for the three months ended March 31, 2016. As of March 31, 2016, the Company had $5,628,880 in cash and cash equivalents and an accumulated deficit of $65,006,548.

On March 31, 2015 and April 10, 2015, we closed on a financing transaction by entering into separate subscription agreements with accredited investors relating to the issuance and sale of an aggregate of $11,714,498 of units (the “Units”) at a purchase price of $0.75 per Unit, with each Unit consisting of one share of our common stock, par value $0.01 per share (or, at the election of any investor who, as a result of receiving common stock would hold in excess of 4.99% of our issued and outstanding common stock, shares of our newly designated 0% Series E Convertible Preferred Stock) and a thirty-month warrant to purchase one half of one share of common stock at an initial exercise price of $1.50 per share, as further described in the Notes to Financial Statements – Equity, (the “April 2015 Private Placement”).

The initial closing of the April 2015 Private Placement took place on March 31, 2015, in which the Company sold an aggregate of $4,995,749 of Units. Following the initial closing the Company entered into separate reconfirmation agreements with the investors in order to extend the initial closing date, increase the offering amount, and adopt a lockup agreement, which was entered by all investors who elected to continue their investment. The second closing was completed on April 10, 2015 for an additional $6,718,751 of Units. The Company issued $2,500,000 of Units consisting of Series E Convertible Preferred Stock on April 10, 2015 and the remainder of Units issued in the April 2015 Private Placement were in the form of common stock Units. Of the total cash received in the second closing on April 10, 2015, $3,500,000 was initially held in escrow under the terms of an escrow agreement with Signature Bank, N.A for a period of 10 weeks pending the approval of a representative of one of the lead investors to release the funds. On June 22, 2015, the Company, Signature Bank, N.A. and OPKO Health, Inc. (“OPKO”) extended the term of the escrow to 16 weeks from the closing of the April 2015 Private Placement. As further consideration for the amendment, on June 30, 2015, the Company and OPKO entered into a letter agreement pursuant to which the Company granted OPKO the right, but not the obligation, until June 30, 2016, to nominate and appoint up to two additional members of the Company’s board of directors (the “Board” or the “Board of Directors”), or to approve the person(s) nominated by the Company pursuant to the agreement in consideration for the release of the escrowed funds. The nominees will be subject to the satisfaction of standard corporate governance practices and any applicable national securities exchange requirements. Upon signing the agreement, the escrowed funds were released to the Company.

Table of Contents

On October 5, 2015, we closed a public offering of 2,500,000 shares of common stock and warrants to purchase 1,250,000 shares of common stock, at an offering price of $1.10 per share. For every two shares of common stock sold, the Company issued one warrant to purchase one share of common stock. The Company received $2,750,000 in gross proceeds, before underwriting discounts and commissions and offering expenses totaling approximately $586,608, and without giving effect to the exercise of the underwriters’ over-allotment option. The Company has been using the net proceeds from this offering to fund the HuMab-5B1 human antibody program through Phase I clinical development and for working capital and general corporate purposes.

The shares and warrants were separately issued and sold in equal proportions. The warrants are immediately exercisable, expire September 30, 2018, and have an exercise price of $1.32 per share. The warrants are not listed on any securities exchange or other trading market. The underwriters did not exercise a 30-day option to purchase up to an additional 375,000 shares of common stock and up to an additional 187,500 warrants at the same price to cover over-allotments, if any.

Under the terms of the underwriting agreement entered into between the Company and the underwriter in the public offering, the Company, without the prior written consent of the underwriter, was prohibited, for a period of 90 days after execution of the underwriting agreement, from issuing any equity securities, subject to certain exceptions.

On October 12, 2015, the Company and investors holding over 60% of the outstanding Registerable Securities (as such term is defined in the Registration Rights Agreements) issued in the April 2015 Private Placement entered into a third amendment agreement to the Registration Rights Agreements to suspend the Company’s registration obligations under the Registration Rights Agreements and related subscription agreements during any period when the “Standstill” provision set forth in the related subscription agreements is in effect. On January 28, 2016, we filed a registration statement with the SEC covering the resale of such registrable securities, which was declared effective by the SEC on February 10, 2016.

On January 15, 2016, the Company and Oxford Finance LLC, as collateral agent and lender, entered into a Loan and Security Agreement providing for senior secured term loans to the Company in an aggregate principal amount of up to $10,000,000, subject to the terms and conditions set forth in the Loan Agreement (the “January 2016 Term Loan”). On January 15, 2016, the Company received an initial loan of $5,000,000 under the Loan Agreement, before fees and issuance costs of approximately $390,000.

We anticipate that the Company will continue to incur net losses into the foreseeable future as we: (i) initiate in the first quarter 2016 Phase I clinical trials planned for our stand-alone therapeutic HuMab 5b-1 and early in 2016 our PET imaging agent 89Zr-HuMab-5B1, (ii) continue to conduct preclinical efforts on several other programs, and (iii) continue operations as a public company. After giving effect to the net proceeds received from the January 2016 Term Loan, management believes that the Company has sufficient funds to meet its obligations through September 2016. These conditions give rise to substantial doubt as to the Company’s ability to continue as a going concern. The accompanying condensed consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

We plan to continue to fund the Company’s losses from operations and capital funding needs through equity or debt financings, strategic collaborations, licensing arrangements, asset sales, government grants or other arrangements. However, we cannot be sure that such additional funds will be available on reasonable terms, or at all. If we are unable to secure adequate additional funding, we may be forced to make reductions in spending, extend payment terms with suppliers, liquidate assets where possible, and/or suspend or curtail planned programs. In addition, if the Company does not meet its payment obligations to third parties as they come due, it may be subject to litigation claims. Even if we are successful in defending against these claims, litigation could result in substantial costs and be a distraction to management. Any of these actions could materially harm the Company’s business, results of operations, and future prospects.

If the Company raises additional funds by issuing equity securities, substantial dilution to existing stockholders would result. If the Company raises additional funds by incurring debt financing, the terms of the debt may involve significant cash payment obligations as well as covenants and specific financial ratios that may restrict the Company’s ability to operate its business.

3. Cash and Cash Equivalents

The Company considers all highly liquid investments purchased with original maturities of three months or less to be cash equivalents. The Company limits its exposure to credit loss by holding cash in U.S. Dollars or, from time to time, placing cash and investments in U.S. government, agency and government-sponsored enterprise obligations.

4. Fair value of financial instruments

The Company’s financial instruments consist of cash and cash equivalents, grants receivable, prepaid expenses and other current assets and accounts payable, all of which are generally considered to be representative of their respective fair values because of the short-term nature of those instruments.

5. Convertible Preferred Stock, Common Stock and Warrants

MabVax Therapeutics Series B preferred stock and warrants (Pre-Merger MabVax Therapeutics Issuances)

Due to the anti-dilution protection in our Series B Warrants (described below), the Series B warrants were recorded as a current liability in the amount of $92,463 on the Company’s condensed consolidated balance sheet as of December 31, 2014. On March 25, 2015, the Series B warrants were re-valued at $72,656 prior to being exchanged into shares of common stock and Series D convertible preferred stock on a one for one basis and the warrant liability was eliminated and the Company recorded a gain of $19,807 for the three months ended March 31, 2015.

Dividends on Preferred Stock

The Company immediately recognizes the changes in the redemption value on preferred stock as they occur and the carrying value of the security is adjusted to equal what the redemption amount would be as if redemption were to occur at the end of the reporting date based on the conditions that exist as of that date. The value adjustment made to the redemption value and preferred stock dividends for the three months ended March 31, 2015, was an increase of $93,234.

Investors in the Private Placement also may be required under certain circumstances to agree to refrain from selling securities underlying the Purchased Units. The liquidated damages for failure to achieve effectiveness of the Registerable Securities is 1% a month 120 days after filing, and provided management has not used commercially reasonable best efforts to have the registration statement declared effective within that time frame.

As the shares granted were fully vested upon grant and the Company has no legal recourse to recover the shares in the event of nonperformance, the Company recognized the grant date fair value of the shares as consulting expense upon grant during the second quarter of 2015.

Livingston Grant

On April 4, 2015, the Board of Directors approved a restricted stock award by the Company of 1,000,000 shares of common stock, valued at $2.30 a share, to be issued to Phil Livingston, Ph.D. for his continuing service to the Company.

The committee further clarified that the vesting of the common stock shall be on the one-year anniversary of the Board of Directors’ approval of the award, or April 4, 2016. The Company is expensing the grant date fair value of the award over the vesting period of one year.

Consulting Agreement

On April 5, 2015, the Company entered into a consulting agreement with The Del Mar Consulting Group, Inc. and Alex Partners, LLC, together, the “Investor Relations Consultants”, pursuant to which such Investor Relations Consultants shall provide investor relations services to the Company in consideration for an immediate grant of 300,000 shares of the Company’s restricted common stock and a monthly cash retainer of $12,000 a month for ongoing services for a period of one year. The consultants also received an additional 200,000 shares of the Company’s restricted common stock upon the Company’s achieving a milestone based on its fully-diluted market capitalization. As the shares granted were fully vested upon grant and the Company has no legal recourse to recover the shares in the event of nonperformance, the Company recognized the grant date fair value of the 300,000 shares or $690,000, as investor relations expense upon grant during the second quarter of 2015. The performance condition for the 200,000 shares became probable and the market capitalization metric was met during the second quarter; therefore, the Company recognized an additional $460,000 of expense during the quarter ended June 30, 2015.

Consultant Grants

As of March 31, 2016, the expected future compensation expense related to these grants is $60,875 based upon the Company’s stock price on March 31, 2016.

On January 13, 2016, the Board of Directors approved the issuance of 100,000 shares of restricted stock valued at $64,000 to a consultant for advisory services to the Company.

6. Notes Payable

On January 15, 2016, we entered into a loan and security agreement with Oxford Finance, LLC pursuant to which we are able to borrow $10,000,000 in two equal tranches of $5,000,000 each (the “Loan and Securities Agreement”). The first tranche of $5,000,000 was funded at close on January 15, 2016 (the “Term A Loan”), and the second tranche of $5,000,000 (the “Term B Loan”) will be funded upon the Company achieving positive interim data on the Phase 1 HuMab-5B1 antibody trial in pancreatic cancer and successfully uplisting to either the NASDAQ Stock Market or NYSE MKT. The interest rate for each term loan is set on a monthly basis at the Index Rate plus 11.29%, where the Index Rate is the greater of the 30-day LIBOR rate or 0.21%. Interest is due on the first day of each month, in arrears, calculated based on a 360-day year. The loan is interest only for the first year after funding, and the principal amount of the loan is amortized in equal principal payments, plus period interest, over the next 36 months. If the Term B Loan is drawn, then the interest only period is extended by 6 months, followed by a 30-month amortization of the principal amount of the loan. A facility fee of 1.0% or $100,000 was due at closing of the transaction, and was earned and paid by the Company on January 15, 2016. The Company is obligated to pay a $150,000 final payment upon completion of the term of the loan and this amount is being accreted using the effective interest rate method over the term of the loan. Each of the term loans can be prepaid subject to a graduated prepayment fee, depending on the timing of the Prepayment.

Table of Contents

Concurrent with the closing of the transaction, the Company granted 1,666,668 common stock purchase warrants to Oxford Finance, LLC with an exercise price of $0.75 per share. The warrants are exercisable for five years and may be exercised on a cashless basis. The Company recorded $607,338 for the relative value of the warrants as a debt discount within notes payable and an increase to additional paid-in capital on the Company’s balance sheet. The debt discount is being amortized as interest expense over the term of the loan using the effective interest method.

We granted Oxford Finance a perfected first priority lien on all of the Company’s assets with a negative pledge on intellectual property. The Company paid Oxford Finance a good faith deposit of $50,000 which was applied towards the facility fee at closing. The Company agreed to pay all costs, fees and expenses incurred by Oxford Finance in the initiation and administration of the facilities including the cost of loan documentation.

At the initial funding, the Company received net proceeds of approximately $4,610,000 after fees and expenses. These fees and expenses are being accounted for as a debt discount and classified within notes payable on the Company’s balance sheet. Consistent with the early adoption of ASU 2015-3, the Company's transaction costs of approximately $390,000 are presented in the balance sheet as a direct deduction from the carrying amount of the notes payable, consistent with debt discounts. Debt discounts, issuance costs and the final payment are being amortized or accreted as interest expense over the term of the loan using the effective interest method.

In connection with the Loan Agreement, the Company issued to the Lenders warrants to purchase 1,666,668 shares of common stock at an exercise price of $0.75 per share. We used the Black-Scholes valuation method to calculate the fair value of the warrant.

The Loan Agreement also contains customary indemnification obligations and customary events of default, including, among other things, our failure to fulfill certain of the Company's obligations under the Loan Agreement, the occurrence of a material adverse change, which is defined as a material adverse change in the Company's business, operations, or condition (financial or otherwise), a material impairment of the prospect of repayment of any portion of the loan, or a material impairment in the perfection or priority of the Lenders’ lien in the collateral or in the value of such collateral. In the event of default by the Company under the Loan Agreement, the Lenders would be entitled to exercise their remedies thereunder, including the right to accelerate payment of the debt, upon which we may be required to repay all amounts then outstanding under the Loan Agreement, which could harm the Company's financial condition.

The Company was in compliance with all applicable covenants set forth in the Loan Agreement as of March 31, 2016.

The Company recorded interest expense related to the term loan of $128,929 for the quarter ended March 31, 2016. The annual effective interest rate on the note payable, including the amortization of the debt discounts and accretion of the final payment, but excluding the warrant amortization, is 11.72%.

Future principal payments under the Loan Agreement as of March 31, 2016 are as follows:

Years ending December 31:
2016	$	—
2017		1,527,777

8. Stock-based Activity

Amendment of Equity Incentive Plan

On March 31, 2015, the Company approved a Second Amended and Restated 2014 Employee, Director and Consultant Equity Incentive Plan (the “Plan”) to increase the number of shares reserved for issuance under the Plan from 158,073 to 8,360,789 shares of common stock. Additional changes to the Plan include:

•

An “evergreen” provision to reserve additional shares for issuance under the Plan on an annual basis commencing on the first day of fiscal 2016 and ending on the second day of fiscal 2024, such that the number of shares that may be issued under the Plan shall be increased by an amount equal to the lesser of: (i) 8,000,000 or the equivalent of such number of shares after the administrator, in its sole discretion, has interpreted the effect of any stock split, stock dividend, combination, recapitalization or similar transaction in accordance with the Plan; (ii) the number of shares necessary such that the total shares reserved under the Plan equals (x) 15% of the number of outstanding shares of common stock on such date (assuming the conversion of all outstanding shares of Preferred Stock (as defined in the Plan) and other outstanding convertible securities and exercise of all outstanding warrants to purchase common stock) plus (y) 229,000; and (iii) an amount determined by the Board;

•

Provide that no more than 3,000,000 shares may be granted to any participant in any fiscal year.

•

Provisions to allow for performance based equity awards to be issued by the Company in accordance with Section 162(m) of the Internal Revenue Code.

Stock-based Compensation

We measure stock-based compensation expense for equity-classified awards, principally related to stock options and restricted stock units, or RSUs, based on the estimated fair value of the award on the date of grant. We recognize the value of the portion of the award that we ultimately expect to vest as stock-based compensation expense over the requisite service period in our condensed consolidated statements of operations. Due to limited activity in 2016 and 2015, we assumed a forfeiture rate of zero.

We use the Black-Scholes model to estimate the fair value of stock options granted. The expected term of stock options granted represents the period of time that we expect them to be outstanding. For the three months ended March 31, 2016 we used volatility of 81.98% to 83.75%, dividend rate of 0%, expected term of 6 years, and risk-free interest rate of 1.23% to 1.43% in our Black-Scholes calculations. There we no stock option grants during the quarter ended March 31, 2015.

Total estimated stock-based compensation expense, related to all of the Company’s stock-based payment awards recognized under ASC 718, “Compensation—Stock Compensation” was comprised of the following:

	Three Months Ended March 31,
	2016		2015
Research and development	$	303,624	$	41,576
General and administrative		1,230,264		41,196
Total share-based compensation expense	$	1,533,888	$	82,772

Because the Company had a net operating loss carryforward as of March 31, 2016, no tax benefits for the tax deductions related to stock-based compensation expense were recognized in the Company’s condensed consolidated statements of operations. Additionally, no stock options were exercised in the three months ended March 31, 2016 and 2015.

A summary of activity related to restricted stock grants under the Plan for the quarter ended March 31, 2016 is presented below:

	Shares		Weighted Average Grant-Date Fair Value
Non-vested at December 31, 2015		2,300,850	$	2.28
Granted		—		—
Vested		—		—
Forfeited		—		—
Non-vested at March 31, 2016		2,300,850	$	2.28

As of March 31, 2016, unamortized compensation expense related to restricted stock grants granted in 2015 amounted to $3,415,151, which is expected to be recognized over a weighted average period of 2.02 years.

Management Bonus Plan

On April 2, 2015, the Compensation Committee of the Board of the Directors approved the 2015 Management Bonus Plan (the “Management Plan”) outlining maximum target bonuses of the base salaries of certain of the Company’s executive officers. Under the terms of the Management Plan, the Company’s Chief Executive Officer shall receive a maximum target bonus of up to 50% of his annual base salary, the Chief Financial Officer shall receive a maximum target bonus of up to 35% of his annual base salary and the Company’s Vice President shall receive a maximum target bonus of up to 25% of his annual base salary.

Common stock reserved for future issuance

Common stock reserved for future issuance consists of the following at March 31, 2016:

Common stock reserved for conversion of preferred stock and warrants			21,662,200
Common stock reserved for exercise of warrants			8,876,336
Common stock options outstanding			4,495,704
Authorized for future grant or issuance under the Stock Plan			1,704,426
Unvested restricted stock			2,300,850
Total			39,039,516

9. Net Loss per Share

The Company calculates basic and diluted net loss per share using the weighted-average number of shares of common stock outstanding during the period.

When the Company is in a net loss position, it excludes from the calculation of diluted net loss per share all potentially dilutive stock options, preferred stock and warrants, and the diluted net loss per share is the same as the basic net loss per share for such periods. If the Company was to be in a net income position, the weighted average number of shares used to calculate the diluted net income per share would include the potential dilutive effect of in-the-money securities, as determined using the treasury stock method.

The table below presents the potentially dilutive securities that would have been included in the calculation of diluted net loss per share if they were not antidilutive for the periods presented.

	As of March 31,
	2016		2015
Stock options		4,495,704		242,893
Preferred stock		21,662,200		23,815,600
Unvested restricted stock		2,300,850		—
Warrants to purchase common stock		8,876,336		3,330,500

NCI PET Imaging Agent Grant

In September 2013, the NCI awarded the Company a SBIR Program Contract to support the Company’s program to develop a PET imaging agent for pancreatic cancer using a fragment of the Company’s 5B1 antibody (the “NCI PET Imaging Agent Grant”). The project period for Phase I of the grant award of approximately $250,000 covered a nine-month period which commenced in September 2013 and ended in June 2014.

On August 25, 2014, the Company was awarded a $1.5 million contract for the Phase II portion of the NCI PET Imaging Agent Grant. The contract is intended to support a major portion of the preclinical work being conducted by the Company, together with its collaboration partner, MSKCC, to develop a novel Positron Emission Tomography (“PET”) imaging agent for detection and assessment of pancreatic cancer. The total contract amount for Phase I and Phase II of approximately $1,749,000 supports research work through June 2016.

The Company records revenue associated with the NCI PET Imaging Agent Grant as the related costs and expenses are incurred. For the three month periods ended March 31, 2016 and 2015, the Company recorded $148,054 and $239,539 of revenue associated with the NCI PET Imaging Agent Grant, respectively.

11. Commitments and contingencies

Litigation

On May 30, 2014, a class action lawsuit was commenced in Santa Clara County Superior Court, State of California, on behalf of Cadillac Partners and others similarly situated, naming as defendants, MabVax Therapeutics, the Company and the Company’s directors, Hudson Bay Capital Management LP, Bio IP Ventures LLC, Hudson Bay Master Fund Ltd., and Hudson Bay IP Opportunities Master Fund LP, together the “Parties”. The suit alleged the defendants breached certain fiduciary duties, or aided and abetted a breach of fiduciary duties, in connection with the Company’s Merger with MabVax Therapeutics. The plaintiff sought to enjoin the Merger and obtain damages as well as attorneys’ and expert fees and costs.

On June 29, 2014, the parties entered into a Stipulation and Settlement (the “Settlement”), pursuant to which the Company agreed to file with the SEC certain supplemental disclosures in connection with the Merger. The Settlement was subject to certain confirmatory discovery to be undertaken by the plaintiff and to the Parties’ agreement on the payment of the plaintiff’s attorneys’ fees and expenses.

On July 16, 2014, the Company and all other parties to the litigation entered into an agreement which, if consummated, would settle the litigation (the “Proposed Settlement”). Among many other terms, under the Proposed Settlement the Company and all defendants will receive a broad release of any and all claims pertaining to the Series B Private Placement, the Merger, the prior disclosure and a wide variety of other matters. The Proposed Settlement also calls for the parties to ask the court to, among other things, enter orders enjoining other stockholders from bringing similar actions, certifying the putative settlement class, and approving the Proposed Settlement as a fair, final, and binding resolution of the litigation. Under the Proposed Settlement, the Company and the other defendants have expressly denied the allegations of the complaint and denied engaging in any other misconduct, nor will any of them make any payment or in any respect amend the negotiated terms of the since-consummated Series B Private Placement and Merger. Finally, under the Proposed Settlement, the Company and the other defendants have not agreed to pay any legal fees, or reimburse any expenses, allegedly incurred by the plaintiffs who filed the complaint; instead, the Company expects that counsel for those plaintiffs will present any such disputed claim for legal fees and expenses to the court for resolution.

On April 20, 2015, the Parties made an application for an Order for Notice and Scheduling of Hearing of Settlement in accordance with a Stipulation of Settlement dated as of April 20, 2015 (the “Action”), which sets forth the terms and conditions for settlement and which provides for dismissal of the Action with prejudice. The Order after Hearing on June 12, 2015, provided preliminary approval of the settlement that was agreed to by the Parties, in which the Company provided supplemental disclosures in the definitive proxy filed with the SEC on June 30, 2014. Notice of the action as a class action was sent to class members in July 2015.

Table of Contents

On September 18, 2015, an Order and Final Judgment was entered by the Superior Court of the State of California, approving the settlement that was agreed upon by both parties and closing the case. The Company anticipates that there will be no additional future expenses incurred in this action by the Company after the December 31, 2015 balance sheet date which would not be offset by insurance.

Operating Leases

In connection with the Merger, the Company recorded a $590,504 contingent lease termination fee, in connection with the termination by MabVax Therapeutics Holdings (f.k.a. Telik, Inc.) of the master lease and sublease of the Porter Drive Facility, which is payable to ARE-San Francisco No. 24 (“ARE”), if the Company receives $15 million or more in additional financing in the aggregate, but otherwise forgiven.

On September 2, 2015, the Company entered into a lease (the “Lease”) with AGP Sorrento Business Complex, L.P., for certain premises of office and laboratory space in buildings located at 11535 Sorrento Valley Rd., San Diego, California, to serve as the Company’s corporate offices and laboratories (the “New Premises”). Due to the fact that certain tenant improvements needed to be made to the New Premises before the Company could take occupancy, the term of the Lease did not commence until the New Premises were ready for occupancy, which was on February 4, 2016. The Lease terminates six years after such term commencement date, unless earlier terminated in accordance with the Lease. Pursuant to the terms of the Lease, the monthly base rent is $35,631, subject to annual increases as set forth in the Lease.

The Company has an option to extend the Lease term for a single, five-year period. If the Lease term is extended for the optional five-year period, the monthly base rent will be adjusted based on fair market rental value. In addition to rent, the Company agreed to pay a portion of the taxes and utility, maintenance and other operating costs paid or accrued in connection with the ownership and operation of the property.

The Company previously leased its corporate office and laboratory space under an operating lease that, as amended on August 1, 2010, expired on July 31, 2015. The lease contained an option to cancel at various dates prior to the termination date by paying a cancellation penalty. The Company has provided a refundable security deposit of $11,017 to secure its obligations under the lease, which was included in other long-term assets in the accompanying condensed consolidated financial statements. We recognize rent expense on a straight-line basis over the term the lease. Rent expense of $122,236 and $115,118 was recognized in the years ended December 31, 2015 and 2014, respectively.

The Company recognized rent expense of $87,683 and $33,050 during the quarter ended March 31, 2016 and 2015, respectively.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

FORWARD LOOKING STATEMENTS

The following discussion should be read in conjunction with our condensed consolidated financial statements and other financial information appearing elsewhere in this quarterly report. In addition to historical information, the following discussion and other parts of this quarterly report contain forward-looking statements. You can identify these statements by forward-looking words such as “plan,” “may,” “will,” “expect,” “intend,” “anticipate,” believe,” “estimate” and “continue” or similar words. Forward-looking statements include information concerning possible or assumed future business success or financial results. You should read statements that contain these words carefully because they discuss future expectations and plans, which contain projections of future results of operations or financial condition or state other forward-looking information. We believe that it is important to communicate future expectations to investors. However, there may be events in the future that we are not able to accurately predict or control. Accordingly, we do not undertake any obligation to update any forward-looking statements for any reason, even if new information becomes available or other events occur in the future and thus you should not unduly rely on these statements.

The forward-looking statements included herein are based on current expectations that involve a number of risks and uncertainties set forth under “Risk Factors” in our Annual Report on Form 10-K as of and for the year ended December 31, 2015, Part II, Section 1A, herein, and other periodic reports filed with the United States Securities and Exchange Commission (“SEC”). Accordingly, to the extent that this Report contains forward-looking statements regarding the financial condition, operating results, business prospects or any other aspect of the Company, please be advised that the Company’s actual financial condition, operating results and business performance may differ materially from that projected or estimated by the Company in forward-looking statements and thus you should not unduly rely on these statements.

Overview

We have been engaged in the discovery, development and commercialization of proprietary human monoclonal antibody products and vaccines for the diagnosis and treatment of a variety of cancers. We have discovered a pipeline of human monoclonal antibody products based on the protective immune responses generated by patients who have been immunized against targeted cancers. Therapeutic vaccines under development were discovered at Memorial Sloan Kettering Cancer Center, or MSK, and are exclusively licensed to MabVax Therapeutics. We operate in only one business segment. We have incurred net losses since inception, and we expect to incur substantial losses for the foreseeable future as we continue our research and development activities. To date, we have funded our operations primarily through government grants, proceeds from the sale of common and preferred stock, the issuance of debt, the issuance of common stock in lieu of cash for services, payments from collaborators and interest income. The process of developing our products will require significant additional research and development, preclinical testing and clinical trials, as well as regulatory approval. We expect these activities, together with general and administrative expenses, to result in substantial operating losses for the foreseeable future. We will not receive product revenue unless we, or our collaborative partners, complete clinical trials, obtain regulatory approval and successfully commercialize one or more of our products. We cannot provide assurance that we will ever generate revenues or achieve and sustain profitability in the future or obtain the necessary working capital for our operations.

During the three months ended March 31, 2016, our loss from operations was $4,204,295 and our net loss was $4,404,770. Net cash used in operating activities for the three months ended March 31, 2016 was $2,911,630 and cash and cash equivalents as of March 31, 2016 were $5,628,880. As of March 31, 2016, we had an accumulated deficit of $65,006,548.

Table of Contents

We are subject to risks common to biopharmaceutical companies, including the need for capital, risks inherent in our research, development and commercialization efforts, preclinical testing, clinical trials, uncertainty of regulatory and marketing approvals, enforcement of patent and proprietary rights, potential competition and retention of key employees. In order for a product to be commercialized, it will be necessary for us to conduct preclinical tests and clinical trials, demonstrate efficacy and safety of our product candidates to the satisfaction of regulatory authorities, obtain marketing approval, enter into manufacturing, distribution and marketing arrangements, obtain market acceptance and, in many cases, obtain adequate reimbursement from government and private insurers. We cannot provide assurance that we will ever generate revenues or achieve and sustain profitability in the future or obtain the necessary working capital for our operations.

Clinical Product Development – Recent Updates

Phase I Clinical Trial of HuMab-5B1 – In March 2016 we announced the initiation of a phase I clinical trial of HuMab-5B1 (MVT-5873) for patients with locally advanced or metastatic adenocarcinoma of the pancreas (PDAC) or other CA19-9 positive malignancies. The CA19-9 target is expressed on more than 90% of pancreatic cancers and is a validated biomarker for the disease. The Company filed an Investigational New Drug (IND) application for this product on November 30, 2015 and received U.S. Food and Drug Administration (FDA) authorization to proceed with the study on December 24, 2015. The study is a phase I, open-label, multi-center, dose-escalation clinical trial. The primary objectives are to determine the safety, maximum tolerated dose (MTD), and the pharmacokinetics (PK) of HuMab-5B1. The phase I trial will also evaluate the tumor response rate based on RECIST 1.1 guidelines for standard tumor measurement and the duration of response of HuMab-5B1 as a single agent or in combination with a standard of care chemotherapy regimen. The study will enroll up to approximately 60 patients at multiple centers in the United States. We expect to have the preliminary results of this clinical trial in the third quarter in 2016, with full results expected in early 2017.

Phase I Clinical Trial of 89Zr-HuMab-5B1 – On January 28, 2016 we received authorization from FDA to proceed with a second phase I clinical trial with [Zr-89]-HuMab-5B1 (MVT-2163) as a new generation PET imaging agent in patients with pancreatic cancer. [Zr-89]-HuMab-5B1 combines a well-established PET imaging radio-label [Zr-89] with the targeting specificity of the HuMab-5B1 antibody. Preclinical xenograft animal models demonstrated high image resolution of tumors, making [Zr-89]-Mab-5B1 attractive as a potential diagnostic agent for use with the HuMab-5B1 therapeutic product. We anticipate the Phase I clinical trial will begin in May 2016. This second planned Phase I trial will evaluate the safety, pharmacokinetics and biodistribution of [Zr-89]-HuMab-5B1 in cancer patients. The trial results are also intended to determine the ideal dose and conditions for an optimal PET scan image using the new imaging agent. We expect to have the preliminary results of this clinical trial by the third quarter 2016, with full results expected in 2017.

Vaccine Trials –Our lead cancer vaccine candidates targeting recurrent sarcoma (soft tissue cancer) and ovarian cancer are currently in proof of concept Phase II multi-center clinical trials. Both the sarcoma and ovarian cancer vaccine trials are randomized, double-blind, multicenter phase II trials that have enrolled 136 and 164 patients respectively. Both trials are designed to yield statistically significant evidence that vaccination of trial subjects can provide 50% improvement in progression free survival, or PFS, and extend overall survival, or OS. Both studies are fully enrolled and all trial subjects have received all vaccinations.

An independent Drug Safety Monitoring Board, or DSMB, composed of experts in the field analyzed the sarcoma clinical trial data in March of 2013 and determined that the PFS endpoint of a 50% increase in the time to progression was not reached. However, the DSMB suggested that we continue to monitor patients to assess OS. We continue to monitor patients and expects the OS endpoint will be available late 2016 or early 2017. If the OS endpoint is achieved, we will pursue outlicensing the product. We currently do not plan to engage in additional clinical studies for this vaccine. We received a National Institutes of Health, or NIH, grant of $1.8 million to help offset the clinical trial costs for the sarcoma trial. We have funded the remainder of the approximately $6 million cost of the trial.

We expect that the PFS endpoint for the ovarian vaccine trial will be reported at the American Society of Clinical Oncology meeting in June 2016. We expect the trial subjects in the ovarian cancer vaccine trial will also continue to be monitored for OS for a period of time following assessment of the PFS endpoint. The ovarian vaccine trial is fully funded by a grant from the NIH. We understand that the NIH has plans to follow patients to determine if there is an OS benefit. MabVax has no financial obligation for this follow-on monitoring. If the OS endpoint is achieved, we will pursue outlicensing the product. We currently do not plan to engage in additional clinical studies for this vaccine..

RESULTS OF OPERATIONS

We are providing the following information about our revenues, expenses, and cash and liquidity.

Comparison of the Three-Month Periods Ended March 31, 2016 and 2015

Revenues:

	Three Months Ended March 31,				% Increase/ (Decrease)
	2016		2015		% Increase/ (Decrease)

Revenues	$	148,054	$	239,539		(38	%)

For the three months ended March 31, 2016, the Company recognized revenues of $148,054, as compared to $239,539 for the same period in the prior year. This decrease was primarily due to timing of the work performed by the Company on the NIH Imaging Contract this year compared to the same period in the prior year.

Research and development expenses:

	Three Months Ended March 31,				% Increase/ (Decrease)
	2016		2015		% Increase/ (Decrease)

Research and development	$	1,700,512	$	1,725,893		(1	%)

For the three months ended March 31, 2016, the Company incurred research and development expenses of $1,700,512, as compared to $1,725,893 for the same period a year ago. Expenses related to the three months ended March 31, 2016, represent primarily clinical development of HuMab 5B1 both as a therapeutic and as a diagnostic, and in-house staffing to support preclinical and clinical development efforts in support of our programs. Expenses in the same period a year ago were primarily for GMP manufacturing development of our lead antibody candidate HuMab 5B1 at Patheon (f.k.a. Gallus BioPharmaceuticals).

Stock-based compensation expense included in research and development expenses for the quarters ended March 31, 2016 and 2015 was $303,624 and $41,576, respectively.

General and administrative expenses:

	Three Months Ended March 31,				% Increase/ (Decrease)
	2016		2015		% Increase/ (Decrease)

General and administrative	$	2,651,837	$	980,589		170	%

For the three months ended March 31, 2016, the Company incurred general and administrative expenses of $2,651,837, as compared to $980,589 for the same period a year ago. The increase in general and administrative expenses was primarily due to a $1,189,068 increase in stock-based compensation expense and the fair value of $64,000 in common stock representing 100,000 shares granted in exchange for corporate advisory services during the three months ended March 31, 2016. The balance of the increase was related to increased facility cost, professional fees related to consulting services, and increased headcount related to business development.

Stock-based compensation expense included in general and administrative expenses for the three months ended March 31, 2016 and 2015 was $1,230,264 and $41,196, respectively. Stock-based compensation expense for the three months ended March 31, 2016 included $573,425 in restricted stock for services.

Interest and other income and expense, net was ($200,475) and ($184) for the quarters ended March 31, 2016 and 2015, respectively. The amount for the three months ended March 31, 2016, consisted primarily of $128,929 interest expense related to interest on the Company’s term loan from Oxford Finance, $31,725 of financing cost amortization, and $39,825 warrant amortization partially offset by interest income of $4. The fair value of the warrants issued to Oxford Finance related to the term loan was recorded as a discount to the value of the note payable, and is amortized over the term of the loan. In addition, financing costs incurred related to the term loan are also amortized over the term of the loan.

Critical Accounting Policies and Significant Judgments and Estimates

Our management’s discussion and analysis of our financial condition and results of operations are based on our condensed consolidated financial statements, which have been prepared in accordance with GAAP. The preparation of these condensed 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 condensed consolidated financial statements as well as the reported revenues and expenses during the reporting periods. On an on-going basis, we evaluate our estimates and judgments related to our operating costs. 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. Actual results may differ significantly from these estimates under different assumptions or conditions.

Our critical accounting policies include:

Revenue recognition. Revenue from grants is based upon internal and subcontractor costs incurred that are specifically covered by the grant, including a facilities and administrative rate that provides funding for overhead expenses. NIH grants are recognized when the Company incurs internal expenses that are specifically related to each grant, in clinical trials at the clinical trial sites, by subcontractors who manage the clinical trials, and provided the grant has been approved for payment. U.S. grant awards are based upon internal research and development costs incurred that are specifically covered by the grant, and revenues are recognized when the Company incurs internal expenses that are related to the approved grant.

Any amounts received by the Company pursuant to the NIH grants prior to satisfying our revenue recognition criteria are recorded as deferred revenue.

Clinical trial expenses. We accrue clinical trial expenses based on work performed. In determining the amount to accrue, we rely on estimates of total costs incurred based on the enrollment of subjects, the completion of trials and other events defined in contracts. We follow this method because we believe reasonably dependable estimates of the costs applicable to various stages of a clinical trial can be made. However, the actual costs and timing of clinical trials are highly uncertain, subject to risks, and may change depending on a number of factors. Differences between the actual clinical trial costs and the estimated clinical trial costs that we have accrued in any prior period are recognized in the subsequent period in which the actual costs become known. Historically, these differences have not been material; however, material differences could occur in the future.

Stock-based compensation. Our stock-based compensation programs include grants of stock options and restricted stock to employees, non-employee directors and non-employee consultants. Stock-based compensation cost is measured at the grant date, based on the calculated fair value of the award, and is recognized as an expense, under the straight-line method, over the employee, non-employee director or non-employee consultant’s requisite service period (generally the vesting period of the equity grant).

We account for equity instruments, including stock options and restricted stock, issued to employees and non-employees in accordance with authoritative guidance for equity based payments. Stock options issued are accounted for at their estimated fair value determined using the Black-Scholes-Merton option-pricing model and restricted stock is accounted for using the grant date fair value of our common stock granted. The fair value of options and restricted stock granted to non-employees is re-measured as they vest, and the resulting increase in value, if any, is recognized as expense during the period the related services are rendered.

Income taxes. Significant judgment is required by management to determine our provision for income taxes, our deferred tax assets and liabilities, and the valuation allowance to record against our net deferred tax assets, which are based on complex and evolving tax regulations throughout the world. Our tax calculation is impacted by tax rates in the jurisdictions in which we are subject to tax and the relative amount of income earned in each jurisdiction. Our deferred tax assets and liabilities are determined using the enacted tax rates expected to be in effect for the years in which those tax assets are expected to be realized.

The effect of an uncertain income tax position is recognized as the largest amount that is “more-likely-than-not” to be sustained under audit by the taxing authority. An uncertain income tax position will not be recognized if it has less than a 50% likelihood of being sustained.

The realization of our deferred tax assets is dependent upon our ability to generate sufficient future taxable income. We establish a valuation allowance when it is more-likely-than-not that the future realization of all or some of the deferred tax assets will not be achieved. The evaluation of the need for a valuation allowance is performed on a jurisdiction-by-jurisdiction basis, and includes a review of all available evidence, both positive and negative. As of March 31, 2016, MabVax Therapeutics concluded that it was more-likely-than-not that its deferred tax assets would not be realized, and a full valuation allowance has been recorded.

The above listing is not intended to be a comprehensive list of all of our accounting policies. In many cases, the accounting treatment of a particular transaction is specifically dictated by GAAP. See our audited consolidated financial statements and notes thereto included in our 2015 Annual Report on Form 10-K, which contain additional accounting policies and other disclosures required by GAAP.

LIQUIDITY AND CAPITAL RESOURCES

To date, we have funded our operations primarily through government grants, proceeds from the sale of common and preferred stock, the issuance of debt, the issuance of common stock in lieu of cash for services, payments from collaborators and interest income. We have experienced negative cash flow from operations each year since our inception. As of March 31, 2016, we had an accumulated deficit of $65,006,548. We expect to continue to incur increased expenses, resulting in losses, over at least the next several years due to, among other factors, our continuing and planned clinical trials and anticipated research and development activities. We had cash of $5,628,880 as of March 31, 2016.

Sources and Uses of Net Cash for the Three Month Period Ended March 31, 2016

Net cash used in operating activities was $2,911,630 for the three-month period ended March 31, 2016, compared to $1,423,530 in the comparable period in 2015. The net cash used in both periods was primarily attributable to the net losses, adjusted to exclude certain non-cash items, primarily stock-based compensation and amortization of finance costs related to the term loan. Net cash used in operating activities for the three months ended March 31, 2016 was also impacted by a decrease of $1,060,796 in accounts payable related primarily to research contract services and a $483,923 decrease in grants receivable.

The net cash used in investing activities for the three-month periods ended March 31, 2016 and 2015, amounted to $153,899 and $28,867, respectively, primarily as a result of purchase of lab equipment in the corresponding periods.

Net cash provided by financing activities was $4,610,324 for the three-month period ended March 31, 2016. Net cash provided by financing activities for the three-month period ended March 31, 2016 was attributable to the net proceeds from the term loan initiated during the first quarter of 2016. Net cash provided by financing activities for the three-month period ended March 31, 2015 was attributable to the net proceeds from the first closing of the April 2015 Private Placement of $4,714,726.

Future Contractual Obligations

The Company had rental payment obligations under an operating lease that expired on July 31, 2015 related to its facility at 11588 Sorrento Valley Road. The Company continued to occupy those premises until February 4, 2016, and continued the lease on a month-to month basis.

On September 2, 2015, the Company entered into a lease (the “Lease”) with AGP Sorrento Business Complex, L.P., for certain premises consisting of a total of approximately 14,971 square feet of office and laboratory space in buildings located at Suite 400, 11535 Sorrento Valley Rd., San Diego, California, to serve as the Company’s corporate offices and laboratories (the “New Premises”). Due to the fact that certain tenant improvements needed to be made to the New Premises before the Company could occupy the New Premises, the term of the Lease commenced on February 4, 2015. The Lease terminates six years after such term commencement date, unless earlier terminated in accordance with the Lease. Pursuant to the terms of the Lease, the monthly base rent is $35,631, subject to annual increases as set forth in the Lease.

Our master lease and sublease of our facility located at 3165 Porter Drive in Palo Alto, California (the “Porter Drive Facility”) were terminated on February 28, 2013 and we entered into a termination agreement with the landlord on February 19, 2013 to voluntarily surrender its premises. As a result of the termination agreement, we were relieved of further obligations under the master lease and further rights to rental income under the sublease and paid a termination fee of approximately $700,000. In addition to the termination fee, if we receive $15 million or more in additional financing in the aggregate, an additional termination fee of $590,504 will be due to the landlord, but will otherwise be forgiven.

We anticipate that we will continue to incur substantial net losses into the foreseeable future as we: (i) continue our Phase I clinical trial for our stand-alone therapeutic HuMab 5b-1, or MVT-5873, which was initiated in the first quarter of 2016, (ii) initiate our Phase I clinical trial of our PET imaging agent 89Zr-HuMab-5B1, or MVT-2163, (iii) continue to conduct preclinical development activities related to other product development candidates in our library, and (iv) monitor patients in clinical trials that have already completed their treatment regimens. Based on management’s assumptions for continuing to develop its existing pipeline of products without additional funding, we expect we will have sufficient funds to meet our obligations through September 2016.

Table of Contents

We plan to continue to fund our research and development and operating activities through public or private equity financings, debt financings, strategic partnerships or other arrangements with organizations that have capabilities and/or products that are complementary to our own capabilities and/or products, licensing arrangements, government grants, or other arrangements. However, we cannot be sure that such additional funds will be available on reasonable terms, or at all. If we are unable to secure adequate additional funding, we may be forced to reduce spending, extend payment terms with suppliers, liquidate assets where possible, and/or suspend or curtail planned programs. In addition, if we do not meet our payment obligations to third parties as they come due, we may be subject to litigation claims. Even if we are successful in defending against these claims, litigation could result in substantial costs and be a distraction to our management. Any of these actions could materially harm our business, results of operations, and future prospects.

If we raise additional funds by issuing equity securities, substantial dilution to our existing stockholders would result. If we raise additional funds by incurring debt financing, the terms of the debt may involve significant cash payment obligations as well as covenants and specific financial ratios that may restrict our ability to operate our business.

Quantitative and Qualitative Disclosures About Market Risk.

Interest Rate Sensitivity

Our cash and cash equivalents of $5,628,880 at March 31, 2016 consisted of cash and money market funds, all of which will be used for working capital purposes. We do not enter into investments for trading or speculative purposes. Our primary exposure to market risk is related to the variability of interest rates on our term loan we entered into with Oxford Finance, LLC in January 2016. Under the loan agreement the interest rate for the term loan is set on a monthly basis at an Index Rate plus 11.29%, where the Index Rate is the greater of the 30-day LIBOR rate or 0.21%. Interest is due on the first day of each month, in arrears, calculated based on a 360-day year. In addition, interest income on our deposits are affected by changes in the general level of interest rates in the United States. Because of the short-term nature of our cash and cash equivalents, we do not believe that we have any material exposure to changes in their fair values as a result of changes in interest rates. The continuation of historically low interest rates in the United States will limit our earnings on investments held in U.S. dollars.

We do not hold any derivative financial instruments or commodity-based instruments.

Controls and Procedures.

Disclosure Controls and Procedures

As required by Rules 13a-15 and 15d-15 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), the Company has evaluated, with the participation of management, including the Chief Executive Officer and the Chief Financial Officer, the effectiveness of its disclosure controls and procedures (as defined in such rules) as of the end of the period covered by this report. The Chief Executive Officer and Chief Financial Officer concluded that the Company’s disclosure controls and procedures are effective as of March 31, 2016.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

Changes in Internal Control over Financial Reporting

As required by Rule 13a-15(d) of the Exchange Act, our management, including our principal executive officer and our principal financial officer, conducted an evaluation of the internal control over financial reporting to determine whether any changes occurred during the period covered by this Quarterly Report on Form 10-Q that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. Based on that evaluation, our principal executive officer and principal financial officer concluded there were no changes in our internal controls over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act) that could significantly affect internal controls over financial reporting as of March 31, 2016.

Risk Factors.

RISK FACTORS

The terms of our secured debt facility require us to meet certain operating and financial covenants and place restrictions on our operating and financial flexibility. If we raise additional capital through debt financing, the terms of any new debt could further restrict our ability to operate our business.

Effective in January 2016, we entered into a $10 million loan and security agreement with Oxford Finance that is secured by a lien covering substantially all of our assets, excluding intellectual property. As of March 31, 2016, we had an outstanding principal balance of $5 million. The loan and security agreement contains customary affirmative and negative covenants and events of default. The affirmative covenants include, among others, covenants requiring us to maintain our legal existence and governmental approvals, deliver certain financial reports and maintain insurance coverage. The negative covenants include, among others, restrictions on transferring collateral, changing our business, incurring additional indebtedness, engaging in mergers or acquisitions, paying dividends or making other distributions, making investments and creating other liens on our assets, in each case subject to customary exceptions. If we default under the loan agreement, the lenders may accelerate all of our repayment obligations and take control of our pledged assets, potentially requiring us to renegotiate our agreement on terms less favorable to us or to immediately cease operations. Further, if we are liquidated, the lender’s right to repayment would be senior to the rights of the holders of our common stock and preferred stock to receive any proceeds from the liquidation. The lenders could declare a default upon the occurrence of any event that they interpret as a material adverse change as defined under the loan agreement, thereby requiring us to repay the loan immediately or to attempt to reverse the declaration of default through negotiation or litigation. Any declaration by the lenders of an event of default could significantly harm our business and prospects and could cause the price of our common stock to decline. If we raise any additional debt financing, the terms of such additional debt could further restrict our operating and financial flexibility.

Other than set forth above, there have been no material changes to the Risk Factors set forth in our Annual Report on Form 10-K for the year ended December 31, 2015.
