Overview

We are engaged in the research and development of non-systemic biologics for the treatment of patients with gastrointestinal disorders. Non-systemic biologics are non-absorbable drugs that act locally, i.e. the intestinal lumen, skin or mucosa, without reaching an individual's systemic circulation.

Our current product pipeline consists of two therapeutic programs under development, each of which are described below.

MS1819-SD

MS1819-SD is a yeast derived recombinant lipase for exocrine pancreatic insufficiency ('EPI') associated with chronic pancreatitis ('CP') and cystic fibrosis ('CF'). A lipase is an enzyme that breaks up fat molecules. MS1819-SD is considered recombinant because it was created from new combinations of genetic material in yeast called Yarrowia lipolytica. In June 2018, the Company completed an open-label, dose escalation Phase 2a trial of MS1819-SD in France, Australia, and New Zealand to investigate both the safety of escalating doses of MS1819-SD, and the efficacy of MS1819-SD through the analysis of each patient's coefficient of fat absorption ('CFA') and its change from baseline. A total of 11 CP patients with EPI were enrolled in the study and final data showed a strong safety and efficacy profile. Although the study was not powered for efficacy, in a pre-planned analysis, the highest dose cohort of MS1819-SD showed statistically significant and clinically meaningful increases in CFA compared to baseline with a mean increase of 21.8% and a p value of p=0.002 on a per protocol basis. Additionally, maximal absolute CFA response to treatment was up to 57%, with an inverse relationship to baseline CFA.

In October 2018, the U.S. Food and Drug Administration ('FDA') cleared the Company's Investigational New Drug ('IND') application for MS1819-SD in patients with EPI due to CF. In connection with the FDA's clearance of the IND, the Company initiated a multi-center Phase 2 OPTION study in the fourth quarter of 2018 in the United States and Europe (the 'OPTION Study'). The Company targeted enrollment of 30 to 35 patients for the OPTION Study and dosed the first patients in February 2019. In June 2019, the Company reached its enrollment target for the study.

On September 25, 2019, the Company announced positive results from the OPTION Study. Results showed that the primary efficacy endpoint of CFA was comparable to the CFA in a prior phase two study in patients with CP, while using the same dosage of MS1819-SD. The dosage used in both studies was 2.2 grams per day, which was determined in agreement with the FDA as a bridging dose. Although the study was not powered for statistical significance, the data demonstrated meaningful efficacy results, with approximately 50% of the patients showing CFAs high enough to reach non-inferiority with standard porcine enzyme replacement therapy ('PERT'). Additionally, coefficient of nitrogen absorption ('CNA') was comparable between the MS1819-SD and PERT arms, 93% vs. 97%, respectively, in the Option Study. This important finding confirms that protease supplementation is not likely to be required with MS1819-SD treatment. A total of 32 patients, ages 18 or older, completed the OPTION Study. The Company recently met with the FDA to discuss a Phase 2b or Phase 3 trial design exploring the use of higher doses and/or enteric-coated capsules to ensure higher levels of MS1819-SD in the duodenum. The new protocol is currently under review with the FDA and a response is anticipated within the next 60 days.



In addition to the OPTION Study, in July 2019 the Company launched a Phase 2 multi-center clinical trial (the 'Combination Trial') in Hungary to investigate MS1819-SD in combination with PERT, for CF patients who suffer from severe EPI, but continue to experience clinical symptoms of fat malabsorption despite taking the maximum daily dose of PERTs. The Combination 2 study is designed to investigate the safety, tolerability and efficacy of escalating doses of MS1819-SD, in conjunction with a stable dose of PERTs, in order to increase CFA and relieve abdominal symptoms.

On October 15, 2019, the Company announced that it dosed the first patients in its Combination Trial. This study is designed to investigate the safety, tolerability and efficacy of escalating doses of MS1819-SD (700 mg, 1120 mg and 2240 mg per day, respectively), in conjunction with a stable dose of porcine PERTs, in order to increase the CFA and relieve abdominal symptoms. A combination therapy of PERT and MS1819-SD has the potential to: (i) correct macronutrient and micronutrient maldigestion; (ii) eliminate abdominal symptoms attributable to maldigestion; and (iii) sustain optimal nutritional status on a normal diet in CF patients with severe EPI. Planned enrollment is expected to include approximately 24 CF patients with severe EPI, with study completion anticipated in 2020.

On October 17, 2019, the Company announced that the Cystic Fibrosis Foundation Data Safety Monitoring Board has completed its review of the Company's final results of the OPTION Study and has found no safety concerns for MS1819-SD, and that the group supports the Company's plan to proceed to a higher four-gram dose of MS1819-SD in its next planned Phase 2 clinical trial.

b-Lactamase Program

Our b-lactamase program focuses on products with an enzymatic combination of bacterial origin for the prevention of hospital-acquired infections and antibiotic-associated diarrhea ('AAD') by resistant bacterial strains induced by parenteral administration of several antibiotic classes. Currently, we have two compounds in pre-clinical development in this program, AZX1101 and AZX1103. Both AZX1101 and AZX1103 are composed of several distinct enzymes that break up individual classes of antibiotic molecules. AZX1103 is a b-lactamase enzyme combination that has shown positive pre-clinical activity, with degradation of amoxicillin in the presence of clavulanic acid in the upper gastrointestinal tract in the Gottingen minipig model. Currently, we are focused on advancing pre-clinical development of AZX1103. We are also currently assessing our plans for the continuation of the development of AZX1101.

We do not expect to generate revenue from drug candidates that we develop until we obtain approval for one or more of such drug candidates and commercialize our product or enter into a collaborative agreement with a third party. We do not have any products approved for sale at the present and have never generated revenue from product sale.

On July 17, 2019, we entered into an underwriting agreement (the 'Underwriting Agreement') with H.C. Wainwright & Co., LLC. ('Wainwright') as representatives of the several underwriters named therein (the 'Underwriters'), relating to the issuance and sale of 5 million shares of our common stock.

Cyber-Related Fraud

On August 8, 2019, management was advised that it was a victim of a cyber-related fraud whereby a hacker impersonated one of the Company's key vendors to redirect payments, totaling $418,765. The Company, including the Audit Committee, completed its investigation and is reviewing all available avenues of recovery, including from the Company's financial institution to recover the payments. As of September 30, 2019, the Company had recovered $50,858 from its financial institution but management is unable to determine the probability of recovering anything further from the cyber-related fraud. Therefore, as of September 30, 2019, the Company recorded a loss of $367,908 which is included in General and Administrative ('G&A') expenses. As a result of the cyber-related fraud, the Company has instituted additional controls and procedures and all employees have now undergone cybersecurity training.

Amendment to Charter and Approved Reverse Stock Split

On December 19, 2019, at the Company's Annual Meeting of Stockholders ('Annual Meeting'), the Company's stockholders approvedan amendment to the Company's Amended and Restated Certificate of Incorporation (the 'Charter') to increase the number of authorized shares of common stock by 50,000,000 shares to 150,000,000 shares, and to authorize the Company's Board of Directors to effect a reverse stock split of both the issued and outstanding and authorized shares of common stock of the Company, at a specific ratio, ranging from one-for-two (1:2) to one-for-five (1:5), any time prior to the one-year anniversary date of the Annual Meeting, with the exact ratio to be determined by the Board of Directors.

The Company filed a Certificate of Amendment to its Charter with the Secretary of State of the State of Delaware on December 20, 2019, to increase the number of authorized shares of common stock to 150,000,000 shares.

December 2019 Convertible Note Offering

On December 20, 2019, the Company began an offering of (i) Senior Convertible Promissory Notes (each a 'Note,' and together, the 'Notes') in the principal amount of up to $8.0 million to certain accredited investors (the 'Investors'), and (ii) warrants ('Warrants') to purchase shares of the Company's common stock, each pursuant to Note Purchase Agreements entered into by and between the Company and each of the Investors (the 'NPAs') (the 'Note Offering').

OnDecember 20, 2019, December 24, 2019, December 30, 2019, December 31, 2019, January 2, 2020, and January 9, 2020, the Company issued Notes to the Investors in the aggregate principal amount of $6,904,000. Each Note matures on September 20, 2020, accrues interest at a rate of 9% per annum, and is convertible, at the option of the holder,into shares of the Company's Common Stock at a price of $0.97 per share (the 'Conversion Shares'). As additional consideration for the execution of the NPA, each Investor also received Warrants to purchase that number of shares of the Company's Common Stock equal to one-half of the Conversion Shares issuable upon conversion of the Notes (the 'Warrant Shares'). The Warrants have an exercise price of $1.07 per share and expire five years from the date of issuance. The Company and each Investor executed a Registration Rights Agreement (the 'RRA'), pursuant to which the Company agreed to file a registration statement with the Securities and Exchange Commission ('SEC') no later than 30 days after the beginning of the Note Offering, on behalf of Investors, to register the Conversion Shares and Warrant Shares.

In connection with the Note Offering,ADEC Private Equity Investments, LLC ('ADEC'), the holder of certain Senior Convertible Notes issued under that certain Note Purchase Agreement, dated as of February 14, 2019, in the aggregate original principal amount of $2.0 million, consented to the issuance of the Notes in the Note Offering in consideration for the repayment, in full, of $554,153.42 remaining due under the terms of the Senior Convertible Notes on or before January 2, 2020, net of the payment to ADEC of $550,000 made by the Company on December 23, 2019 from proceeds from the issuance of the Notes and a payment of $1.0 million on December 31, 2019, from the anticipated issuance of additional Notes.

Equity Offering

On November 13, 2019 (the 'Execution Date'), we entered into a purchase agreement, dated as of the Execution Date (the 'Purchase Agreement'), and a registration rights agreement, dated as of the Execution Date (the 'Registration Rights Agreement'), with Lincoln Park Capital Fund, LLC ('Lincoln Park'), pursuant to which Lincoln Park has committed to purchase up to $15,000,000 of the Company's common stock. Pursuant to the Registration Rights Agreement, the Company is required to register the maximum number of shares of common stock that have been or may be issued to Lincoln Park under the Purchase Agreement and as shall be permitted to be registered in accordance with applicable rules, regulations and interpretations of the SEC. We have filed the registration statement with the SEC that includes this prospectus to register for resale under the Securities Act of 1933, as amended, (the 'Securities Act'), up to 8,880,760 shares of common stock, representing 33.33% of the issued and outstanding shares of common stock on November 13, 2019.

Under the terms and subject to the conditions of the Purchase Agreement, the Company has the right, but not the obligation, to sell to Lincoln Park, and Lincoln Park is obligated to purchase up to $15,000,000 of shares of common stock. Such sales of common stock by the Company, if any, will be subject to certain limitations, and may occur from time to time, at the Company's sole discretion, over the 30-month period commencing on the date that a registration statement covering the resale of shares of common stock that have been and may be issued under the Purchase Agreement, which the Company agreed to file with the SEC pursuant to the Registration Rights Agreement, is declared effective by the SEC, a final prospectus in connection therewith is filed and the other conditions set forth in the Purchase Agreement are satisfied, all of which are outside the control of Lincoln Park (such date on which all of such conditions are satisfied, the 'Commencement Date'). The Company has 60 business days to file the registration statement. In consideration for entering into the Purchase Agreement, we previously issued to Lincoln Park 487,168 shares of common stock as a commitment fee on November 13, 2019.

Thereafter, under the Purchase Agreement, on any business day over the term of the Purchase Agreement, the Company has the right, in its sole discretion, to present Lincoln Park with a purchase notice (each, a 'Purchase Notice') directing Lincoln Park to purchase up to 150,000 shares per business day (the 'Regular Purchase') (subject to adjustment for any reorganization, recapitalization, non-cash dividend, stock split, reverse stock split or other similar transaction as provided in the Purchase Agreement). In each case, Lincoln Park's maximum commitment in any single Regular Purchase may not exceed $1,000,000. The Purchase Agreement provides for a purchase price per Purchase Share (the 'Purchase Price') equal to the lesser of the lowest sale price of the Company's common stock on the purchase date; and the average of the three lowest closing sale prices for the Company's common stock during the ten consecutive business days ending on the business day immediately preceding the purchase date of such shares.

In addition, on any date on which the Company submits a Purchase Notice to Lincoln Park, the Company also has the right, in its sole discretion, to present Lincoln with an accelerated purchase notice (each, an 'Accelerated Purchase Notice') directing Lincoln Park to purchase an amount of stock (the 'Accelerated Purchase') equal to up to the lesser of (i) three times the number of shares purchased pursuant to such Regular Purchase; and (ii) 30% of the aggregate shares of the Company's common stock traded during all or, if certain trading volume or market price thresholds specified in the Purchase Agreement are crossed on the applicable Accelerated Purchase date, the portion of the normal trading hours on the applicable Accelerated Purchase date prior to such time that any one of such thresholds is crossed (such period of time on the applicable Accelerated Purchase Date, the 'Accelerated Purchase Measurement Period'), provided that Lincoln Park will not be required to buy shares pursuant to an Accelerated Purchase Notice that was received by Lincoln Park on any business day on which the last closing trade price of the Company's common stock on The Nasdaq Capital Market (or alternative national exchange in accordance with the Purchase Agreement) is below $0.25 per share. The purchase price per share for each such Accelerated Purchase will be equal to the lesser of 97% of the volume weighted average price of the Company's common stock during the applicable Accelerated Purchase Measurement Period on the applicable Accelerated Purchase date; and the closing sale price of the Company's common stock on the applicable Accelerated Purchase Date.

The Company may also direct Lincoln Park on any business day on which an Accelerated Purchase has been completed and all of the shares to be purchased thereunder have been properly delivered to Lincoln Park in accordance with the Purchase Agreement, to purchase an amount of stock (the 'Additional Accelerated Purchase') equal to up to the lesser of (i) three times the number of shares purchased pursuant to such Regular Purchase; and (ii) 30% of the aggregate number of shares of the Company's common stock traded during a certain portion of the normal trading hours on the applicable Additional Accelerated Purchase date as determined in accordance with the Purchase Agreement (such period of time on the applicable Additional Accelerated Purchase date, the 'Additional Accelerated Purchase Measurement Period'), provided that the closing price of the Company's common stock on the business day immediately preceding such business day is not below $0.25 (subject to adjustment for any reorganization, recapitalization, non-cash dividend, stock split, reverse stock split or other similar transaction as provided in the Purchase Agreement). Additional Accelerated Purchases will be equal to the lower of 97% of the volume weighted average price of the Company's common stock during the applicable Additional Accelerated Purchase Measurement Period on the applicable Additional Accelerated Purchase date; and the closing sale price of the Company's common stock on the applicable Additional Accelerated Purchase date.

As of November 13, 2019, there were 26,155,111 shares of our common stock issued and outstanding immediately prior to the execution of the Purchase Agreement, of which 23,504,132 shares were held by non-affiliates. Although the Purchase Agreement provides that we may sell up to $15,000,000 of our common stock to Lincoln Park, only 8,880,760 shares of our common stock are being offered under this prospectus, which represents shares which may be issued to Lincoln Park in the future under the Purchase Agreement, if and when we sell shares to Lincoln Park under the Purchase Agreement. Depending on the market prices of our common stock at the time we elect to issue and sell shares to Lincoln Park under the Purchase Agreement, we may need to register for resale under the Securities Act additional shares of our common stock in order to receive aggregate gross proceeds equal to the $15,000,000 total commitment available to us under the Purchase Agreement. If all of the 8,880,760 shares offered by Lincoln Park under this prospectus were issued and outstanding as of the date hereof, such shares would represent approximately 25.2% of the total number of shares of our common stock issued and outstanding and approximately 27.2% of the total number of issued and outstanding shares held by non-affiliates, in each case as of the date hereof. If we elect to issue and sell more than the 8,880,760 shares offered under this prospectus to Lincoln Park, which we have the right, but not the obligation, to do, we must first register for resale under the Securities Act any such additional shares, which could cause additional substantial dilution to our stockholders. The number of shares ultimately offered for resale by Lincoln Park is dependent upon the number of shares we sell to Lincoln Park under the Purchase Agreement.

Under applicable rules of The Nasdaq Capital Market, in no event may we issue or sell to Lincoln Park under the Purchase Agreement more than 19.99% of the shares of our common stock outstanding immediately prior to the execution of the Purchase Agreement (which is 5,231,022 shares based on 26,155,111 shares issued and outstanding immediately prior to the execution of the Purchase Agreement), which limitation we refer to as the Exchange Cap, unless (i) we obtain stockholder approval to issue shares of common stock in excess of the Exchange Cap or (ii) the average of the closing prices of our common stock on The Nasdaq Capital Market for the five business days immediately preceding November 13, 2019 plus an incremental amount, such that issuances and sales of our common stock to Lincoln Park under the Purchase Agreement would be exempt from the Exchange Cap limitation under applicable Nasdaq rules. In any event, the Purchase Agreement specifically provides that we may not issue or sell any shares of our common stock under the Purchase Agreement if such issuance or sale would breach any applicable Nasdaq rules.

The Purchase Agreement also prohibits us from directing Lincoln Park to purchase any shares of common stock if those shares, when aggregated with all other shares of our common stock then beneficially owned by Lincoln Park and its affiliates, would result in Lincoln Park and its affiliates having beneficial ownership, at any single point in time, of more than 9.99% of the then total outstanding shares of our common stock, as calculated pursuant to Section 13(d) of the Securities Exchange Act of 1934, as amended, or the Exchange Act, and Rule 13d-3 thereunder (the 'Beneficial Ownership Cap').

Issuances of our common stock in this offering will not affect the rights or privileges of our existing stockholders, except that the economic and voting interests of each of our existing stockholders will be diluted as a result of any such issuance. Although the number of shares of common stock that our existing stockholders own will not decrease, the shares owned by our existing stockholders will represent a smaller percentage of our total outstanding shares after any such issuance to Lincoln Park.

As a result of the consummation of the Notes Financing as discussed inDecember 2019 Convertible Note Offeringabove in this prospectus, which resulted in the issuance of Notes convertible into approximately 7.1 million shares of our common stock, the number of shares of common stock that we can issue to Lincoln Park under the rules of the Nasdaq Capital Market on orbefore July 2020 may be limited in the event the price of our common stock declines below $0.70 per share unless we obtain stockholder approval of such issuances.

Investing in our common stock involves a high degree of risk. Before deciding whether to purchase our securities, including the shares of common stock and warrants offered by this prospectus, you should carefully consider the risks and uncertainties described under 'Risk Factors' in our Annual Report on Form 10-K for the fiscal year ended December 31, 2018, any subsequent Quarterly Report on Form 10-Q and our other filings with the SEC, all of which are incorporated by reference herein. If any of these risks actually occur, our business, financial condition and results of operations could be materially and adversely affected and we may not be able to achieve our goals, the value of our securities could decline and you could lose some or all of your investment. Additional risks not presently known to us or that we currently believe are immaterial may also significantly impair our business operations. If any of these risks occur, our business, results of operations or financial condition and prospects could be harmed. In that event, the market price of our common stock and the value of the warrants could decline, and you could lose all or part of your investment.

Risks Related to this Offering

The number of shares that may be issued to Lincoln Park under the terms of the Purchase Agreement may be limited due to the requirements of the Nasdaq Capital Market.

As a result of the issuance of certain Senior Convertible Promissory Notes ('Notes') in December 2019 and January 2020 in the aggregate principal amount of approximately $6.9 million (the 'Notes Financing'), which Notes are convertible into approximately 7.1 million shares of our common stock, the number of shares of common stock that we can issue to Lincoln Park under the rules of the Nasdaq Capital Market on orbefore July 2020 may be limited in the event the price of our common stock declines below $0.70 per share unless we obtain stockholder approval of such issuances. In the event we do not obtain stockholder approval, and the price of our common stock declines below $0.70 per share, the Company may be unable to issue shares of common stock to Lincoln Park under the Purchase Agreement prior to July 2020.

A default in the Company's ability to repay the Notes when due and payable on September 20, 2020 in the principal amount of approximately $6.9 million would have a material adverse effect on our financial condition and therefore our ability to continue as a going concern.

The Company issued certain Notes in the aggregate principal amount of approximately $6.9 million in December 2019 and January 2020, which become due and payable September 20, 2020. The Notesare convertible into shares of our common stock at $0.97 per share. In the event all or a portion of the holders of such Notes fail to convert such Notes into common stock of the Company prior to the maturity date, and the Company is unable to refinance or otherwise pay such Notes in full at maturity, such failure would result in a default under the terms of the Notes. Such default would have a material adverse effect on our financial condition and therefore our ability to continue as a going concern.

The sale or issuance of our common stock to Lincoln Park may cause dilution and the sale of the shares of common stock acquired by Lincoln Park, or the perception that such sales may occur, could cause the price of our common stock to fall.

On November 13, 2019, we entered into the Purchase Agreement with Lincoln Park, pursuant to which Lincoln Park has committed to purchase up to $15,000,000 of our common stock. Upon the execution of the Purchase Agreement, we issued 487,168 Commitment Shares to Lincoln Park as a fee for its commitment to purchase shares of our common stock under the Purchase Agreement. The remaining shares of our common stock that may be issued under the Purchase Agreement may be sold by us to Lincoln Park at our discretion from time to time over a 30-month period commencing after the satisfaction of certain conditions set forth in the Purchase Agreement, including that the SEC has declared effective the registration statement that includes this prospectus. The purchase price for the shares that we may sell to Lincoln Park under the Purchase Agreement will fluctuate based on the price of our common stock. Depending on market liquidity at the time, sales of such shares may cause the trading price of our common stock to fall.

We generally have the right to control the timing and amount of any future sales of our shares to Lincoln Park. Additional sales of our common stock, if any, to Lincoln Park will depend upon market conditions and other factors to be determined by us. We may ultimately decide to sell to Lincoln Park all, some or none of the additional shares of our common stock that may be available for us to sell pursuant to the Purchase Agreement. If and when we do sell shares to Lincoln Park, after Lincoln Park has acquired the shares, Lincoln Park may resell all, some or none of those shares at any time or from time to time in its discretion. Therefore, sales to Lincoln Park by us could result in substantial dilution to the interests of other holders of our common stock. Additionally, the sale of a substantial number of shares of our common stock to Lincoln Park, or the anticipation of such sales, could make it more difficult for us to sell equity or equity-related securities in the future at a time and at a price that we might otherwise wish to effect sales.

We may require additional financing to sustain our operations and without it we may not be able to continue operations.

We may direct Lincoln Park to purchase up to $15,000,000 worth of shares of our common stock under our agreement over a 30-month period generally in amounts up to 150,000 shares of our common stock, which share amount may be increased to include additional shares of our common stock depending on the market price of our common stock at the time of sale, and subject to a maximum limit of $1,000,000 per purchase, on any such business day. Assuming a purchase price of $1.30 per share (the average of the high and low prices per share on January 8, 2020) and the purchase by Lincoln Park of the balance of the 8,393,592 purchase shares, proceeds to us would only be approximately $10.9 million.

The extent we rely on Lincoln Park as a source of funding will depend on a number of factors including, the prevailing market price of our common stock and the extent to which we are able to secure working capital from other sources. If obtaining sufficient funding from Lincoln Park were to prove unavailable or prohibitively dilutive, we will need to secure another source of funding in order to satisfy our working capital needs. Even if we sell all $15,000,000 under the Purchase Agreement to Lincoln Park, we may still need additional capital to fully implement our business, operating and development plans. Should the financing we require to sustain our working capital needs be unavailable or prohibitively expensive when we require it, the consequences could be a material adverse effect on our business, operating results, financial condition and prospects.

We have included important factors in the cautionary statements included in this prospectus, as well as certain information incorporated by reference into this prospectus, that could cause actual future results or events to differ materially from the forward-looking statements that we make.

DIVIDEND POLICY

We have never declared or paid any cash dividends on our capital stock, and we do not currently intend to pay any cash dividends on our common stock for the foreseeable future. We expect to retain future earnings, if any, to fund the development and growth of our business. Any future determination to pay dividends on our common stock will be at the discretion of our board of directors and will depend upon, among other factors, our results of operations, financial condition, capital requirements and any contractual restrictions.

This prospectus relates to the resale by the selling stockholder, Lincoln Park, of shares of common stock that have been or may be issued to Lincoln Park pursuant to the Purchase Agreement. We are filing the registration statement of which this prospectus forms a part pursuant to the provisions of the Registration Rights Agreement, which we entered into with Lincoln Park on November 13, 2019 concurrently with our execution of the Purchase Agreement, in which we agreed to provide certain registration rights with respect to sales by Lincoln Park of the shares of our common stock that have been or may be issued to Lincoln Park under the Purchase Agreement.

Lincoln Park, as the selling stockholder, may, from time to time, offer and sell pursuant to this prospectus any or all of the shares that we have issued or may sell to Lincoln Park under the Purchase Agreement. The selling stockholder may sell some, all or none of its shares. We do not know how long the selling stockholder will hold the shares before selling them, and we currently have no agreements, arrangements or understandings with the selling stockholder regarding the sale of any of the shares.

The following table presents information regarding the selling stockholder and the shares that it may offer and sell from time to time under this prospectus. The table is prepared based on information supplied to us by the selling stockholder, and reflects its holdings as of January 8, 2020.

Messrs. Cope and Scheinfeld have shared voting and investment power over the shares being offered under the prospectus filed with the SEC in connection with the transactions contemplated under the Purchase Agreement.

The 567,011 shares issuable upon conversion of outstanding senior convertible notes and the 612,018 shares underlying warrants that are beneficially owned by Lincoln Park are subject to blocker provisions which restrict the exercise or conversion of such instruments if, as a result of such exercise or conversion, Lincoln Park, the holder, together with its affiliates and any other person whose beneficial ownership of Common Stock would be aggregated with Lincoln Park for purposes of Section 13(d) of the Exchange Act, would cause Lincoln Park to beneficially own in excess of 4.99% or 9.99% of our then issued and outstanding shares of Common Stock. The senior convertible notes and warrants held by Lincoln Park were previously acquired in one or more transactions not related to the transactions contemplated by the Purchase Agreement, and the shares issuable upon conversion of the outstanding senior convertible notes and the shares underlying warrants are not being registered under the registration statement of which this prospectus is a part. In accordance with Rule 13d-3(d) under the Exchange Act, we have excluded from the number of shares beneficially owned prior to the offering all of the shares of common stock that Lincoln Park may be required to purchase pursuant to the Purchase Agreement because the issuance of such shares is solely at our discretion and is subject to certain conditions, the satisfaction of all of which are outside of Lincoln Park's control, including the registration statement of which this prospectus is a part becoming and remaining effective. Furthermore, under the terms of the Purchase Agreement, issuances and sales of shares of our common stock to Lincoln Park are subject to certain limitations on the amounts we may sell to Lincoln Park at any time, including the Exchange Cap and the Beneficial Ownership Cap. See the description under the heading 'The Lincoln Park Transaction' for more information about the Purchase Agreement.

Although the Purchase Agreement provides that we may sell up to $15,000,000 of our common stock to Lincoln Park in addition to the 487,168 shares that have already been issued to Lincoln Park, only 8,880,760 shares of our common stock are being offered under this prospectus that may be sold by us to Lincoln Park at our discretion from time to time over a 30-month period commencing after the date of the Commencement. Depending on the price per share at which we sell our common stock to Lincoln Park pursuant to the Purchase Agreement, we may need to sell to Lincoln Park under the Purchase Agreement more shares of our common stock than are offered under this prospectus in order to receive aggregate gross proceeds equal to the $15,000,000 total commitment available to us under the Purchase Agreement. If we choose to do so, we must first register for resale under the Securities Act such additional shares. The number of shares ultimately offered for resale by Lincoln Park is dependent upon the number of shares we sell to Lincoln Park under the Purchase Agreement.

General

On November 13, 2019, we entered into a Purchase Agreement and Registration Rights Agreement with Lincoln Park. Pursuant to the terms of the Purchase Agreement, Lincoln Park has agreed to purchase from us up to $15,000,000 of our common stock from time to time during the term of the Purchase Agreement, subject to certain limitations.

We do not have the right to commence any sales to Lincoln Park under the Purchase Agreement until the Commencement has occurred. Thereafter, we may, from time to time and at our sole discretion, on any single business day, direct Lincoln Park to purchase shares of our common stock in amounts up to 150,000 shares, which amounts may be increased depending on the market price of our common stock at the time of sale and subject to a maximum commitment by Lincoln Park of $1,000,000 per single purchase ('RegularPurchases'). In addition, at our discretion, Lincoln Park has committed to purchase other amounts under an Accelerated Purchase (as defined below) and/or additional amounts under an Additional Accelerated Purchase (as defined below) under certain circumstances. The purchase price per share sold will be based on the market price of our common stock immediately preceding the time of sale as computed under the Purchase Agreement. Lincoln Park may not assign or transfer its rights and obligations under the Purchase Agreement.

Under applicable rules of The Nasdaq Capital Market, in no event may we issue or sell to Lincoln Park under the Purchase Agreement share of our common stock in excess of the Exchange Cap (which is 5,231,022 shares, or 19.99% of the shares of our common stock outstanding immediately prior to the execution of the Purchase Agreement), unless (i) we obtain stockholder approval to issue shares of common stock in excess of the Exchange Cap or (ii) the average price of all applicable sales of our common stock to Lincoln Park under the Purchase Agreement equals or exceeds the average of the closing prices of our common stock on The Nasdaq Capital Market for the five business days immediately preceding November 13, 2019 plus an incremental amount, such that issuances and sales of our common stock to Lincoln Park under the Purchase Agreement would be exempt from the Exchange Cap limitation under applicable Nasdaq rules. In any event, the Purchase Agreement specifically provides that we may not issue or sell any shares of our common stock under the Purchase Agreement if such issuance or sale would breach any applicable rules Nasdaq rules.

The Purchase Agreement also prohibits us from directing Lincoln Park to purchase any shares of common stock if those shares, when aggregated with all other shares of our common stock then beneficially owned by Lincoln Park and its affiliates, would result in Lincoln Park exceeding the Beneficial Ownership Cap.

Pursuant to the Registration Rights Agreement, the Company is required to register the maximum number of shares of common stock that have been or may be issued to Lincoln Park under the Purchase Agreement and as shall be permitted to be registered in accordance with applicable rules, regulations and interpretations of the SEC. We have filed the registration statement with the SEC that includes this prospectus to register for resale under the Securities Act, up to 8,880,760 shares of common stock, representing approximately 34% of the issued and outstanding shares of common stock on November 13, 2019.

Purchase of Shares Under the Purchase Agreement

Under the terms and subject to the conditions of the Purchase Agreement, the Company has the right, but not the obligation, to sell to Lincoln Park, and Lincoln Park is obligated to purchase up to $15,000,000 of shares of common stock. Such sales of common stock by the Company, if any, will be subject to certain limitations, and may occur from time to time, at the Company's sole discretion, over the 30-month period commencing on the date that a registration statement covering the resale of shares of common stock that have been and may be issued under the Purchase Agreement, which the Company agreed to file with the SEC pursuant to the Registration Rights Agreement, is declared effective by the SEC and a final prospectus in connection therewith is filed and the other conditions set forth in the Purchase Agreement are satisfied, all of which are outside the control of Lincoln Park (such date on which all of such conditions are satisfied, the 'Commencement Date'). The Company has 60 business days to file the registration statement.

Thereafter, under the Purchase Agreement, on any business day over the term of the Purchase Agreement, the Company has the right, in its sole discretion, to present Lincoln Park with a purchase notice (each, a 'Purchase Notice') directing Lincoln Park to purchase up to 150,000 shares per business day (the 'Regular Purchase'), (subject to adjustment for any reorganization, recapitalization, non-cash dividend, stock split, reverse stock split or other similar transaction as provided in the Purchase Agreement). In each case, Lincoln Park's maximum commitment in any single Regular Purchase may not exceed $1,000,000. The Purchase Agreement provides for a purchase price per Purchase Share (the 'Purchase Price') equal to the lesser of:

the lowest sale price of the Company's common stock on the purchase date; and

the average of the three lowest closing sale prices for the Company's common stock during the ten consecutive business days ending on the business day immediately preceding the purchase date of such shares.

In addition, on any date on which the Company submits a Purchase Notice to Lincoln Park, the Company also has the right, in its sole discretion, to present Lincoln with an accelerated purchase notice (each, an 'Accelerated Purchase Notice') directing Lincoln Park to purchase an amount of stock (the 'Accelerated Purchase') equal to up to the lesser of (i) three times the number of shares purchased pursuant to such Regular Purchase; and (ii) 30% of the aggregate shares of the Company's common stock traded during all or, if certain trading volume or market price thresholds specified in the Purchase Agreement are crossed on the applicable Accelerated Purchase date, the portion of the normal trading hours on the applicable Accelerated Purchase date prior to such time that any one of such thresholds is crossed (such period of time on the applicable Accelerated Purchase Date, the 'Accelerated Purchase Measurement Period'), provided that Lincoln Park will not be required to buy shares pursuant to an Accelerated Purchase Notice that was received by Lincoln Park on any business day on which the last closing trade price of the Company's common stock on The Nasdaq Capital Market (or alternative national exchange in accordance with the Purchase Agreement) is below $0.25 per share. The purchase price per share for each such Accelerated Purchase will be equal to the lesser of:

97% of the volume weighted average price of the Company's common stock during the applicable Accelerated Purchase Measurement Period on the applicable Accelerated Purchase date; and

the closing sale price of the Company's common stock on the applicable Accelerated Purchase Date.

The Company may also direct Lincoln Park on any business day on which an Accelerated Purchase has been completed and all of the shares to be purchased thereunder have been properly delivered to Lincoln Park in accordance with the Purchase Agreement, to purchase an amount of stock (the 'Additional Accelerated Purchase') equal to up to the lesser of (i) three times the number of shares purchased pursuant to such Regular Purchase; and (ii) 30% of the aggregate number of shares of the Company's common stock traded during a certain portion of the normal trading hours on the applicable Additional Accelerated Purchase date as determined in accordance with the Purchase Agreement (such period of time on the applicable Additional Accelerated Purchase date, the 'Additional Accelerated Purchase Measurement Period'), provided that the closing price of the Company's common stock on the business day immediately preceding such business day is not below $0.25 (subject to adjustment for any reorganization, recapitalization, non-cash dividend, stock split, reverse stock split or other similar transaction as provided in the Purchase Agreement). Additional Accelerated Purchases will be equal to the lower of:

97% of the volume weighted average price of the Company's common stock during the applicable Additional Accelerated Purchase Measurement Period on the applicable Additional Accelerated Purchase date; and

the closing sale price of the Company's common stock on the applicable Additional Accelerated Purchase date.

In the case of the regular purchases, accelerated purchases and additional accelerated purchases, the purchase price per share will be equitably adjusted for any reorganization, recapitalization, non-cash dividend, stock split, reverse stock split or other similar transaction occurring during the business days used to compute the purchase price.

Other than as described above, there are no trading volume requirements or restrictions under the Purchase Agreement, and we will control the timing and amount of any sales of our common stock to Lincoln Park.

Events of Default

Events of default under the Purchase Agreement include the following:

the effectiveness of a registration statement registering the resale of the Securities lapses for any reason (including, without limitation, the issuance of a stop order or similar order) or such registration statement (or the prospectus forming a part thereof) is unavailable to the Investor for resale of any or all of the Securities to be issued to the Investor under the Transaction Documents, and such lapse or unavailability continues for a period of ten (10) consecutive Business Days or for more than an aggregate of thirty (30) Business Days in any 365-day period, but excluding a lapse or unavailability where (i) the Company terminates a registration statement after the Investor has confirmed in writing that all of the Securities covered thereby have been resold or (ii) the Company supersedes one registration statement with another registration statement, including (without limitation) by terminating a prior registration statement when it is effectively replaced with a new registration statement covering Securities (provided in the case of this clause (ii) that all of the Securities covered by the superseded (or terminated) registration statement that have not theretofore been resold are included in the superseding (or new) registration statement);

the suspension of the common stock from trading on the Principal Market for a period of one (1) Business Day, provided that the Company may not direct the Investor to purchase any shares of common stock during any such suspension;

(or nationally recognized successor to any of the foregoing);

If at any time after the Commencement Date, the Exchange Cap is exceeded unless and until stockholder approval is obtained pursuant to the Purchase Agreement. The Exchange Cap shall be deemed to be exceeded at such time if, upon submission of a Regular Purchase Notice or Accelerated Purchase Notice under this Agreement, the issuance of such shares of common stock would exceed that number of shares of common stock which the Company may issue under this Agreement without breaching the Company's obligations under the rules or regulations of the Principal Market;

the failure for any reason by the Transfer Agent to issue Purchase Shares to the Investor within three (3) Business Days after the applicable Purchase Date, Accelerated Purchase Date or Additional Accelerated Purchase Date (as applicable) on which the Investor is entitled to receive such Purchase Shares;

the Company breaches any representation, warranty, covenant or other term or condition under any Transaction Document if such breach has or could have a Material Adverse Effect and except, in the case of a breach of a covenant which is reasonably curable, only if such breach continues for a period of at least five (5) Business Days;

if any Person commences a proceeding against the Company pursuant to or within the meaning of any Bankruptcy Law;

if the Company is at any time insolvent, or, pursuant to or within the meaning of any Bankruptcy Law, (i) commences a voluntary case, (ii) consents to the entry of an order for relief against it in an involuntary case, (iii) consents to the appointment of a Custodian of it or for all or substantially all of its property, or (iv) makes a general assignment for the benefit of its creditors or is generally unable to pay its debts as the same become due;

a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that (i) is for relief against the Company in an involuntary case, (ii) appoints a Custodian of the Company or for all or substantially all of its property, or (iii) orders the liquidation of the Company or any Subsidiary; or

if at any time the Company is not eligible to transfer its common stock electronically as DWAC Shares.

Lincoln Park does not have the right to terminate the Purchase Agreement upon any of the events of default set forth above. During an event of default, all of which are outside of Lincoln Park's control, we may not direct Lincoln Park to purchase any shares of our common stock under the Purchase Agreement.

Our Termination Rights

We have the unconditional right, at any time, for any reason and without any payment or liability to us, to give notice to Lincoln Park to terminate the Purchase Agreement. In the event of bankruptcy proceedings by or against us, the Purchase Agreement will automatically terminate without action of any party.

No Short-Selling or Hedging by Lincoln Park

Lincoln Park has agreed that neither it nor any of its affiliates shall engage in any direct or indirect short-selling or hedging of our common stock during any time prior to the termination of the Purchase Agreement.

Effect of Performance of the Purchase Agreement on Our Stockholders

All 8,880,760 shares registered in this offering which have been or may be issued or sold by us to Lincoln Park under the Purchase Agreement are expected to be freely tradable. It is anticipated that shares registered in this offering will be sold over a period of up to 30-months commencing on the date that the registration statement including this prospectus becomes effective. The sale by Lincoln Park of a significant amount of shares registered in this offering at any given time could cause the market price of our common stock to decline and to be highly volatile. Sales of our common stock to Lincoln Park, if any, will depend upon market conditions and other factors to be determined by us. We may ultimately decide to sell to Lincoln Park all, some or none of the additional shares of our common stock that may be available for us to sell pursuant to the Purchase Agreement. If and when we do sell shares to Lincoln Park, after Lincoln Park has acquired the shares, Lincoln Park may resell all, some or none of those shares at any time or from time to time in its discretion. Therefore, sales to Lincoln Park by us under the Purchase Agreement may result in substantial dilution to the interests of other holders of our common stock. In addition, if we sell a substantial number of shares to Lincoln Park under the Purchase Agreement, or if investors expect that we will do so, the actual sales of shares or the mere existence of our arrangement with Lincoln Park may make it more difficult for us to sell equity or equity-related securities in the future at a time and at a price that we might otherwise wish to effect such sales. However, we have the right to control the timing and amount of any additional sales of our shares to Lincoln Park and the Purchase Agreement may be terminated by us at any time at our discretion without any cost to us.

Pursuant to the terms of the Purchase Agreement, we have the right, but not the obligation, to direct Lincoln Park to purchase up to $15,000,000 of our common stock. Depending on the price per share at which we sell our common stock to Lincoln Park pursuant to the Purchase Agreement, we may need to sell to Lincoln Park under the Purchase Agreement more shares of our common stock than are offered under this prospectus in order to receive aggregate gross proceeds equal to the $15,000,000 total commitment available to us under the Purchase Agreement. If we choose to do so, we must first register for resale under the Securities Act such additional shares of our common stock, which could cause additional substantial dilution to our stockholders. The number of shares ultimately offered for resale by Lincoln Park under this prospectus is dependent upon the number of shares we direct Lincoln Park to purchase under the Purchase Agreement.

The Purchase Agreement prohibits us from issuing or selling to Lincoln Park under the Purchase Agreement (i) shares of our common stock in excess of the Exchange Cap, unless we obtain stockholder approval to issue shares in excess of the Exchange Cap or the average price of all applicable sales of our common stock to Lincoln Park under the Purchase Agreement equal or exceed the average of the closing prices of our common stock on The Nasdaq Capital Market for the five business days immediately preceding November 13, 2019 plus an incremental amount, such that the transactions contemplated by the Purchase Agreement are exempt from the Exchange Cap limitation under applicable Nasdaq rules, and (ii) any shares of our common stock if those shares, when aggregated with all other shares of our common stock then beneficially owned by Lincoln Park and its affiliates, would exceed the Beneficial Ownership Cap.

The following table sets forth the amount of gross proceeds we would receive from Lincoln Park from our sale of shares to Lincoln Park under the Purchase Agreement at varying purchase prices:

Includes the total number of purchase shares which we would have sold under the Purchase Agreement at the corresponding assumed purchase price per share set forth in the adjacent column, which does not include the 487,168 commitment shares previously issued to Lincoln Park. Although the Purchase Agreement provides that we may sell up to $15,000,000 of our common stock to Lincoln Park, we are only registering 8,880,760 shares (including the 487,168 commitment shares previously issued to Lincoln Park) under this prospectus, which may or may not cover all the shares we ultimately sell to Lincoln Park under the Purchase Agreement, depending on the purchase price per share. As a result, we have included in this column only those shares that we are registering in this offering. If we seek to issue shares of our common stock, including shares from other transactions that may be aggregated with the transactions contemplated by the Purchase Agreement under the applicable rules of The Nasdaq Capital Market, in excess of 5,213,022 shares, or 19.99% of the total common stock outstanding immediately prior to the execution of the Purchase Agreement unless the average price per share exceeds the average of the closing prices of our common stock on The Nasdaq Capital Market for the five business days immediately preceding November 13, 2019 plus an incremental amount, such that issuances and sales of our common stock to Lincoln Park under the Purchase Agreement would be exempt from the Exchange Cap limitation under applicable Nasdaq rules, we may be required to seek stockholder approval to maintain compliance with the rules of The Nasdaq Capital Market.

The denominator is based on 26,800,519 shares outstanding as of January 8, 2020, which includes (i) 487,168 commitment shares issued to Lincoln Park upon the execution of the Purchase Agreement and (ii) the number of shares set forth in the adjacent column which we would have sold to Lincoln Park, assuming the purchase price in the adjacent column. The numerator is based on the number of shares issuable under the Purchase Agreement at the corresponding assumed purchase price set forth in the adjacent column.

The common stock offered by this prospectus is being offered by the selling stockholder, Lincoln Park. The common stock may be sold or distributed from time to time by the selling stockholder directly to one or more purchasers or through brokers, dealers, or underwriters who may act solely as agents at market prices prevailing at the time of sale, at prices related to the prevailing market prices, at negotiated prices, or at fixed prices, which may be changed. The sale of the common stock offered by this prospectus could be affected in one or more of the following methods:

ordinary brokers' transactions;

transactions involving cross or block trades;

through brokers, dealers, or underwriters who may act solely as agents;

'at the market' into an existing market for the common stock;

in other ways not involving market makers or established business markets, including direct sales to purchasers or sales effected through agents;

in privately negotiated transactions; or

any combination of the foregoing.

In order to comply with the securities laws of certain states, if applicable, the shares may be sold only through registered or licensed brokers or dealers. In addition, in certain states, the shares may not be sold unless they have been registered or qualified for sale in the state or an exemption from the state's registration or qualification requirement is available and complied with.

Lincoln Park is an 'underwriter' within the meaning of Section 2(a)(11) of the Securities Act.

Lincoln Park has informed us that it intends to use an unaffiliated broker-dealer to effectuate all sales, if any, of the common stock that it may purchase from us pursuant to the Purchase Agreement. Such sales will be made at prices and at terms then prevailing or at prices related to the then current market price. Each such unaffiliated broker-dealer will be an underwriter within the meaning of Section 2(a)(11) of the Securities Act. Lincoln Park has informed us that each such broker-dealer will receive commissions from Lincoln Park that will not exceed customary brokerage commissions.

Brokers, dealers, underwriters or agents participating in the distribution of the shares as agents may receive compensation in the form of commissions, discounts, or concessions from the selling stockholder and/or purchasers of the common stock for whom the broker-dealers may act as agent. The compensation paid to a particular broker-dealer may be less than or in excess of customary commissions. Neither we nor Lincoln Park can presently estimate the amount of compensation that any agent will receive.

We know of no existing arrangements between Lincoln Park or any other stockholder, broker, dealer, underwriter or agent relating to the sale or distribution of the shares offered by this prospectus. At the time a particular offer of shares is made, a prospectus supplement, if required, will be distributed that will set forth the names of any agents, underwriters or dealers and any compensation from the selling stockholder, and any other required information.

We will pay the expenses incident to the registration, offering, and sale of the shares to Lincoln Park. We have agreed to indemnify Lincoln Park and certain other persons against certain liabilities in connection with the offering of shares of common stock offered hereby, including liabilities arising under the Securities Act or, if such indemnity is unavailable, to contribute amounts required to be paid in respect of such liabilities. Lincoln Park has agreed to indemnify us against liabilities under the Securities Act that may arise from certain written information furnished to us by Lincoln Park specifically for use in this prospectus or, if such indemnity is unavailable, to contribute amounts required to be paid in respect of such liabilities.

Lincoln Park has represented to us that at no time prior to the Purchase Agreement has Lincoln Park or its agents, representatives or affiliates engaged in or effected, in any manner whatsoever, directly or indirectly, any short sale (as such term is defined in Rule 200 of Regulation SHO of the Exchange Act) of our common stock or any hedging transaction, which establishes a net short position with respect to our common stock. Lincoln Park agreed that during the term of the Purchase Agreement, it, its agents, representatives or affiliates will not enter into or effect, directly or indirectly, any of the foregoing transactions.

We have advised Lincoln Park that it is required to comply with Regulation M promulgated under the Exchange Act. With certain exceptions, Regulation M precludes the selling stockholder, any affiliated purchasers, and any broker-dealer or other person who participates in the distribution from bidding for or purchasing, or attempting to induce any person to bid for or purchase any security which is the subject of the distribution until the entire distribution is complete. Regulation M also prohibits any bids or purchases made in order to stabilize the price of a security in connection with the distribution of that security. All of the foregoing may affect the marketability of the securities offered by this prospectus.

This offering will terminate on the earlier of (i) termination of the Purchase Agreement or (ii) the date that all shares offered by this prospectus have been sold by Lincoln Park.

Anti-Takeover Effects of Certain Provisions of Delaware Law and of the Company's Certificate of Incorporation and Bylaws

Certain provisions of Delaware law, our Charter and Bylaws discussed below may have the effect of making more difficult or discouraging a tender offer, proxy contest or other takeover attempt. These provisions are expected to encourage persons seeking to acquire control of our company to first negotiate with our Board of Directors. We believe that the benefits of increasing our ability to negotiate with the proponent of an unfriendly or unsolicited proposal to acquire or restructure our company outweigh the disadvantages of discouraging these proposals because negotiation of these proposals could result in an improvement of their terms.

Delaware Anti-Takeover Law.

We are subject to Section 203 of the Delaware General Corporation Law. Section 203 generally prohibits a public Delaware corporation from engaging in a 'business combination' with an 'interested stockholder' for a period of three years after the date of the transaction in which the person became an interested stockholder, unless:

prior to the date of the transaction, the Board of Directors of the corporation approved either the business combination or the transaction which resulted in the stockholder becoming an interested stockholder;

upon consummation of the transaction that resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced, excluding specified shares; or

at or subsequent to the date of the transaction, the business combination is approved by the Board of Directors and authorized at an annual or special meeting of stockholders, and not by written consent, by the affirmative vote of at least 66 2/3% of the outstanding voting stock which is not owned by the interested stockholder.

Section 203 defines a 'business combination' to include:

any merger or consolidation involving the corporation and the interested stockholder;

any sale, lease, exchange, mortgage, pledge, transfer or other disposition of 10% or more of the assets of the corporation to or with the interested stockholder;

subject to exceptions, any transaction that results in the issuance or transfer by the corporation of any stock of the corporation to the interested stockholder;

subject to exceptions, any transaction involving the corporation that has the effect of increasing the proportionate share of the stock of any class or series of the corporation beneficially owned by the interested stockholder; or

the receipt by the interested stockholder of the benefit of any loans, advances, guarantees, pledges or other financial benefits provided by or through the corporation.

In general, Section 203 defines an 'interested stockholder' as any person that is:

the owner of 15% or more of the outstanding voting stock of the corporation;

an affiliate or associate of the corporation who was the owner of 15% or more of the outstanding voting stock of the corporation at any time within three years immediately prior to the relevant date; or

the affiliates and associates of the above.

Under specific circumstances, Section 203 makes it more difficult for an 'interested stockholder' to effect various business combinations with a corporation for a three-year period, although the stockholders may, by adopting an amendment to the corporation's certificate of incorporation or bylaws, elect not to be governed by this section, effective 12 months after adoption.

Our Charter and Bylaws do not exclude us from the restrictions of Section 203. We anticipate that the provisions of Section 203 might encourage companies interested in acquiring us to negotiate in advance with our Board of Directors since the stockholder approval requirement would be avoided if a majority of the directors then in office approve either the business combination or the transaction that resulted in the stockholder becoming an interested stockholder.

Charter and Bylaws.

Provisions of our Charter and Bylaws may delay or discourage transactions involving an actual or potential change of control or change in our management, including transactions in which stockholders might otherwise receive a premium for their shares, or transactions that our stockholders might otherwise deem to be in their best interests. Therefore, these provisions could adversely affect the price of our common stock.

Amended and Restated 2014 Omnibus Equity Incentive Plan

The Board and stockholders have adopted and approved the 2014 Plan, which is a comprehensive incentive compensation plan under which we can grant equity-based and other incentive awards to our officers, employees, directors, consultants and advisers. The purpose of the 2014 Plan is to help us attract, motivate and retain such persons with awards under the 2014 Plan and thereby enhance stockholder value.

Administration. The 2014 Plan is administered by the Compensation Committee of the Board, which consists of three members of the Board, each of whom is a 'non-employee director' within the meaning of Rule 16b-3 promulgated under the Securities Exchange Act of 1934, as amended (the 'Exchange Act'), an 'outside director' within the meaning of Section 162(m) of the Internal Revenue Code (the 'Code'). Among other things, the Compensation Committee has complete discretion, subject to the express limits of the 2014 Plan, to determine the directors, employees and nonemployee consultants to be granted an award, the type of award to be granted the terms and conditions of the award, the form of payment to be made and/or the number of shares of common stock subject to each award, the exercise price of each option and base price of each stock appreciation right ('SAR'), the term of each award, the vesting schedule for an award, whether to accelerate vesting, the value of the common stock underlying the award, and the required withholding, if any. The Compensation Committee may amend, modify or terminate any outstanding award, provided that the participant's consent to such action is required if the action would impair the participant's rights or entitlements with respect to that award. The Compensation Committee is also authorized to construe the award agreements, and may prescribe rules relating to the 2014 Plan. Notwithstanding the foregoing, the Compensation Committee does not have any authority to grant or modify an award under the 2014 Plan with terms or conditions that would cause the grant, vesting or exercise thereof to be considered nonqualified 'deferred compensation' subject to Code Section 409A.

Grant of Awards; Shares Available for Awards. The 2014 Plan provides for the grant of stock options, SARs, performance share awards, performance unit awards, distribution equivalent right awards, restricted stock awards, restricted stock unit awards and unrestricted stock awards to non-employee directors, officers, employees and nonemployee consultants of the Company or its affiliates. The aggregate number of shares of common stock that may be issued under the 2014 Plan shall not exceed 10% of the issued and outstanding shares of common stock on an as converted basis (the 'As Converted Shares'), on a rolling basis. For calculation purposes, the As Converted Shares shall include all shares of common stock and all shares of common stock issuable upon the conversion of outstanding preferred stock and other convertible securities, but shall not include any shares of common stock issuable upon the exercise of options, warrants and other convertible securities issued pursuant to the 2014 Plan. The number of authorized shares of common stock reserved for issuance under the 2014 Plan shall automatically be increased concurrently with our issuance of fully paid and non-assessable shares of As Converted Shares. Shares shall be deemed to have been issued under the 2014 Plan solely to the extent actually issued and delivered pursuant to an award. If any award expires, is cancelled, or terminates unexercised or is forfeited, the number of shares subject thereto is again available for grant under the 2014 Plan.

The number of shares of common stock for which awards may be granted under the 2014 Plan to a participant who is an employee in any calendar year is limited to 300,000 shares. Future new hires and additional non-employee directors and/or consultants would be eligible to participate in the 2014 Plan as well. The number of stock options and/or shares of restricted stock to be granted to executives and directors cannot be determined at this time as the grant of stock options and/or shares of restricted stock is dependent upon various factors such as hiring requirements and job performance.

Stock Options. The 2014 Plan provides for either 'incentive stock options' ('ISOs'), which are intended to meet the requirements for special federal income tax treatment under the Code, or 'nonqualified stock options' ('NQSOs'). Stock options may be granted on such terms and conditions as the Compensation Committee may determine; provided, however, that the per share exercise price under a stock option may not be less than the fair market value of a share of common stock on the date of grant and the term of the stock option may not exceed 10 years (110% of such value and five years in the case of an ISO granted to an employee who owns (or is deemed to own) more than 10% of the total combined voting power of all classes of the Company's capital stock or a parent or subsidiary of the Company). ISOs may only be granted to employees. In addition, the aggregate fair market value of common stock covered by one or more ISOs (determined at the time of grant), which are exercisable for the first time by an employee during any calendar year may not exceed $100,000. Any excess is treated as a NQSO.

Stock Appreciation Rights. A SAR entitles the participant, upon exercise, to receive an amount, in cash or stock or a combination thereof, equal to the increase in the fair market value of the underlying common stock between the date of grant and the date of exercise. SARs may be granted in tandem with, or independently of, stock options granted under the 2014 Plan. A SAR granted in tandem with a stock option (i) is exercisable only at such times, and to the extent, that the related stock option is exercisable in accordance with the procedure for exercise of the related stock option; (ii) terminates upon termination or exercise of the related stock option (likewise, the common stock option granted in tandem with a SAR terminates upon exercise of the SAR); (iii) is transferable only with the related stock option; and (iv) if the related stock option is an ISO, may be exercised only when the value of the stock subject to the stock option exceeds the exercise price of the stock option. A SAR that is not granted in tandem with a stock option is exercisable at such times as the Compensation Committee may specify.

Performance Shares and Performance Unit Awards. Performance share and performance unit awards entitle the participant to receive cash or shares of common stock upon the attainment of specified performance goals. In the case of performance units, the right to acquire the units is denominated in cash values.

Distribution Equivalent Right Awards. A distribution equivalent right award entitles the participant to receive bookkeeping credits, cash payments and/or common stock distributions equal in amount to the distributions that would have been made to the participant had the participant held a specified number of shares of common stock during the period the participant held the distribution equivalent right. A distribution equivalent right may be awarded as a component of another award under the 2014 Plan, where, if so awarded, such distribution equivalent right will expire or be forfeited by the participant under the same conditions as under such other award.

Restricted Stock Awards and Restricted Stock Unit Awards. A restricted stock award is a grant or sale of common stock to the participant, subject to our right to repurchase all or part of the shares at their purchase price (or to require forfeiture of such shares if issued to the participant at no cost) in the event that conditions specified by the Compensation Committee in the award are not satisfied prior to the end of the time period during which the shares subject to the award may be repurchased by or forfeited to us. Restricted stock units entitle the participant to receive a cash payment equal to the fair market value of a share of common stock for each restricted stock unit subject to such restricted stock unit award, if the participant satisfies the applicable vesting requirement.

Unrestricted Stock Awards. An unrestricted stock award is a grant or sale of shares of our common stock to the participant that is not subject to transfer, forfeiture or other restrictions, in consideration for past services rendered to the Company or an affiliate or for other valid consideration.

Change-in-Control Provisions. In connection with the grant of an award, the Compensation Committee may provide that, in the event of a change in control, such award will become fully vested and immediately exercisable.

Amendment and Termination. The Compensation Committee may adopt, amend and rescind rules relating to the administration of the 2014 Plan, and amend, suspend or terminate the 2014 Plan, but no such amendment or termination will be made that materially and adversely impairs the rights of any participant with respect to any award received thereby under the 2014 Plan without the participant's consent, other than amendments that are necessary to permit the granting of awards in compliance with applicable laws.

Compensation Committee Interlocks and Insider Participation

No executive officers of the Company serve on the Compensation Committee (or in a like capacity) for the Company or any other entity.

Policy and Procedures Governing Related Party Transactions

The Board is committed to upholding the highest legal and ethical conduct in fulfilling its responsibilities and recognizes that related party transactions can present a heightened risk of potential or actual conflicts of interest.

The SEC rules define a related party transaction to include any transaction, arrangement or relationship which: (i) we are a participant; (ii) the amount involved exceeds $120,000; and (iii) executive officer, director or director nominee, or any person who is known to be the beneficial owner of more than 5% of our common stock, or any person who is an immediate family member of an executive officer, director or director nominee or beneficial owner of more than 5% of our common stock had or will have a direct or indirect material interest.

Although we do not maintain a formal written procedure for the review and approval of transactions with such related persons, it is our policy for the disinterested members of our Board to review all related party transactions on a case-by-case basis. To receive approval, a related-party transaction must have a legitimate business purpose for us and be on terms that are fair and reasonable to us and our stockholders and as favorable to us and our stockholders as would be available from non-related entities in comparable transactions.

All related party transactions must be disclosed in our applicable filings with the SEC as required under SEC rules.

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Exchange Act, requires our officers, directors, and persons who beneficially own more than 10% of our common stock to file reports of ownership and changes in ownership with the SEC.
