Overview
 
We are engaged in the research and development of targeted, non-systemic therapies for the treatment of patients with gastrointestinal (“GI”) diseases. Non-systemic therapies are non-absorbable drugs that act locally, i.e. the intestinal lumen, skin or mucosa, without reaching an individual’s systemic circulation. 
 
We are currently focused on developing our pipeline of three gut-restricted GI clinical drug candidates. The lead therapeutic candidate is MS1819, a recombinant lipase for the treatment of exocrine pancreatic insufficiency (“EPI”) in patients with cystic fibrosis and chronic pancreatitis, currently in two Phase 2 clinical trials. We plan to launch two clinical programs using proprietary formulations of niclosamide, a pro-inflammatory pathway inhibitor; FW-420, for grade 1 Immune Checkpoint Inhibitor-Associated Colitis (“ICI-AC”) and diarrhea in oncology patients and FW-1022, for Severe Acute Respiratory Syndrome Coronavirus 2 (“COVID-19” or “COVID”) gastrointestinal infections. Each drug candidate is described below:
  
MS1819
 
MS1819 is a recombinant lipase enzyme for the treatment of exocrine pancreatic insufficiency (“EPI”) associated with cystic fibrosis (“CF”) and chronic pancreatitis (“CP”). MS1819, supplied as an oral non-systemic biologic capsule, is derived from the Yarrowia lipolytica yeast lipase and breaks up fat molecules in the digestive tract of EPI patients so that they can be absorbed as nutrients. Unlike the standard of care, the MS1819 synthetic lipase does not contain any animal products.
 
EPI is a condition characterized by deficiency of the exocrine pancreatic enzymes, resulting in a patient’s inability to digest food properly, or maldigestion. The deficiency in this enzyme can be responsible for greasy diarrhea, fecal urge and weight loss. There are more than 30,000 patients with EPI caused by CF according to the Cystic Fibrosis Foundation approximately and approximately 90,000 patients in the U.S. with EPI caused by CP according to the National Pancreas Foundation. Patients are currently treated with porcine pancreatic enzyme replacement pills (“PERT”).
  
MS1819 – Phase 2b OPTION 2 Cystic Fibrosis Monotherapy Studies
 
On October 17, 2019, we announced that the Cystic Fibrosis Foundation Data Safety Monitoring Board (the “CFF DSMB”) completed its review of our final results of the OPTION Cross-Over Study and had found no safety concerns for MS1819, and that the CFF DSMB supported our plan to proceed to a higher 4.4 gram dose of MS1819 with enteric capsules in the multi-center dose escalation Phase 2b OPTION clinical trial (the “OPTION 2 Trial”). In December 2019, the Company submitted the clinical trial protocol to the existing IND at the FDA. The clinical trial protocol has been reviewed by the FDA with no comments. In April 2020, the Company received approval to conduct the OPTION 2 Trial in Therapeutics Development Network (“TDN”) clinical sites in the U.S. as well as Institutional Review Board (“IRB”) approval to commence the OPTION 2 Trial.
 
 
 
 
 
  
 
 
 
 
 
 
 
 
The OPTION 2 Trial is designed to investigate the safety, tolerability and efficacy of MS1819 (2.2 gram and 4.4 gram doses in enteric capsules) in a head-to-head manner versus the current standard of care, porcine pancreatic enzyme replacement therapy (PERT”) pills. The OPTION 2 Trial will be an open-label, crossover study, conducted in 15 sites in the U.S. and Europe. A total of 30 CF patients 18 years or older will be enrolled.  MS1819 will be administered in enteric capsules to provide gastric protection and allow optimal delivery of enzyme to the duodenum.  Patients will first be randomized into two cohorts: to either the MS1819 arm, where they receive a 2.2 gram daily oral dose of MS1819 for three weeks; or to the PERT arm, where they receive their pre-study dose of PERT pills for three weeks. After three weeks, stools will be collected for analysis of coefficient of fat absorption (CFA”). Patients will then be crossed over for another three weeks of the alternative treatment. After three weeks of cross-over therapy, stools will again be collected for analysis of CFA. A parallel group of patients will be randomized and studied in the same fashion, using a 4.4 gram daily dose of MS1819. All patients will be followed for an additional two weeks after completing both crossover treatments for post study safety observation. Patients will be assessed using descriptive methods for efficacy, comparing CFA between MS1819 and PERT arms, and for safety.
 
We initiated the OPTION 2 Trial in July 2020 with the first patient screened and three clinical trial sites activated in the U.S. In August 2020, the Company dosed the first patients and initiated the European arm of the OPTION 2 Trial. Topline data is anticipated in the first quarter of 2021; however, this timeline may be further delayed due to the COVID-19 pandemic.  
 
In November 2020, we submitted a protocol amendment for the OPTION 2 Trial to add a study arm that uses an immediate release MS1819 capsule to compare data from the existing arm, that uses delayed-release enteric capsules with data from the new arm, that uses immediate release capsules, in order to determine the optimal dose and delivery method. We plan to initiate the OPTION 2 study extension in early first quarter 2021.
 
MS1819 – Phase 2 Combination Therapy Study
 
In addition to the monotherapy studies, we launched a Phase 2 multi-center clinical trial (the “Combination Trial”) in Europe to investigate MS1819 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 Trial is designed to investigate the safety, tolerability and efficacy of escalating doses of MS1819 (700 mg, 1120 mg and 2240 mg per day, respectively), in conjunction with a stable dose of PERTs, in order to increase CFA and relieve abdominal symptoms in uncontrolled CF patients. A combination therapy of PERT and MS1819 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.
 
We dosed the first patients in its Combination Trial in Hungary in October 2019. Planned enrollment is expected to include approximately 24 CF patients with severe EPI, at clinical trial sites in Hungary and additional countries in Europe, including Turkey. Topline data is currently expected in the first half of 2021; however, this timeline may be further delayed due to the COVID-19 pandemic.
 
We announced positive interim data on the first five patients in the Combination Trial in August 2020. The primary efficacy endpoint was met, with CFAs greater than 80% for all patients across all visits. For secondary efficacy endpoints, we observed that stool weight decreased, the number of stools per day decreased, steatorrhea improved, and body weight increased. Additionally, no serious adverse events were reported.
 
We opened a total of five clinical sites for the Combination Trial in Turkey in October 2020 and announced that its first patients were dosed in November 2020. We currently have a total of nine of the expected ten sites in Europe active and recruiting patients.
 
License Agreement with First Wave Bio, Inc.
 
On December 31, 2020, we entered into a License Agreement (the “First Wave License Agreement”) with First Wave Bio, Inc. (“First Wave”). Pursuant to the First Wave License Agreement, First Wave granted us a worldwide, exclusive right to develop, manufacture, and commercialize First Wave’s proprietary immediate release and enema formulations of niclosamide for the fields of treating ICI-AC and COVID in humans (the “Product”). The Product uses First Wave’s proprietary formulations of niclosamide, a pro-inflammatory pathway inhibitor. We plan to commence in 2021 both a Phase 2 trial of the Product for COVID in GI and a Phase 1b/2a trial for ICI-AC.
    
 
 
 
 
 
 
 
 
 
 
 
 
In consideration of the license and other rights granted by First Wave, we paid First Wave a $9.0 million upfront cash payment and an additional payment of $1.25 million due on June 30, 2021. In addition, we are obligated to pay potential milestone payments to First Wave totaling up to $37.0 million for each indication, based upon the achievement of specified development and regulatory milestones. We are also obligated to pay First Wave royalties as a mid-single digit percentage of net sales of the Product, subject to specified reductions.
 
We are now solely responsible, and have agreed to use commercially reasonable efforts, for all development, regulatory and commercial activities related to the Products in the ICI-AC and COVID fields. We may sublicense our rights under the First Wave License Agreement and, if we do so, we will be obligated to pay milestone payments and royalties to First Wave based on the sublicensee’s development and commercialization of the Products.
 
Pursuant to the First Wave License Agreement, First Wave retains rights to develop and commercialize the licensed niclosamide formulations outside the ICI-AC and COVID fields, and to develop and commercialize other niclosamide formulations that are not licensed to us. However, if prior to April 30, 2021, First Wave seeks to outlicense, sell to or otherwise grant rights to a third party related to any products containing niclosamide for use outside the ICI-AC or COVID fields to develop or commercialize a product containing niclosamide for use outside of the field then First Wave shall provide to us written notice of such proposal, in reasonable detail and we shall have the right and option to negotiate with First Wave with respect to a definitive agreement for the acquisition of First Wave. Pursuant to the First Wave License Agreement, we grant First Wave a worldwide, non-exclusive, royalty-free, perpetual, irrevocable license for use outside the ICI-AC and COVID fields, with the right to grant sublicenses, under any program IP and other intellectual property owned by us and incorporated into the Product.
 
The First Wave License Agreement terminates on a country-by-country basis and product-by-product basis upon the expiration of the royalty term for such product in such country. Each royalty term begins on the date of the first commercial sale of the licensed product in the applicable country and ends on date of expiration of the last to expire royalty term with respect to the country. The First Wave License Agreement may be terminated earlier in specified situations, including termination for uncured material breach of the First Wave License Agreement by either party, termination by us in specified circumstances, termination by First Wave in specified circumstances, termination by us for convenience with advance notice, and termination upon a party’s insolvency or bankruptcy. After expiration of the royalty term, we shall have a non-exclusive, fully-paid, perpetual, royalty-free right and irrevocable license with respect to any Product in any country within the territory.
 
The First Wave License Agreement also contains customary representations, warranties and covenants by both parties, as well as customary provisions relating to indemnification, confidentiality and other matters.
 
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 sales.

The terms and conditions of the Series B Preferred Stock and the Series B Offering were reported in our Current Report on Form 8-K filed July 20, 2020, which is incorporated herein by reference.
 
On December 31, 2020, we entered into a securities purchase agreement (the “Series C Purchase Agreement”) with a certain accredited investor, pursuant to which we agreed to sell in a registered direct offering (the “Series C Registered Direct Offering”) 5,333.333 shares of our Series C 9.00% Convertible Junior Preferred Stock, par value $0.0001 per share (the “Series C Preferred Stock”), at a price of $750 per share, which shares were initially convertible into an aggregate of 5,333,334 shares of Common Stock, at an initial stated value of $750.00 per share and a conversion price of $0.75 per share. The Series C Registered Direct Offering closed on January 6, 2021.
  
Concurrently with the Series C Registered Direct Offering, in a private placement (the “Series C Private Placement,” and together with the Series C Registered Direct Offering, the “Series C Offerings”), we also sold to the investor, an additional 5,333.333 shares of Series C Preferred Stock at the same price as the Series C Preferred Stock offered in the Series C Registered Direct Offering, which shares were initially convertible into an aggregate of 5,333,334 shares of our Common stock, together with warrants to purchase up to an aggregate of 10,666,668 shares of Common Stock, with an exercise price of $0.80 per share and an expiration term through July 6, 2026.

DESCRIPTION OF TRANSACTIONS
  
Series B Exchange Right
 
       On July 16, 2020, we consummated the Series B Offering in which we issued an aggregate of 2,912.583005 shares of Series B Preferred Stock, at a price of $7,700.00 per share, initially convertible into an aggregate of 29,125,756 shares of Common Stock at $0.77 per share, together with the Series B Warrants to purchase an aggregate of 14,562,826 shares of Common Stock at an exercise price of $0.85 per share.
 
Under the Series B Certificate of Designations, in the event we effect any issuance of Common Stock or common stock equivalents for cash consideration, or a combination of units thereof, each holder of the Series B Preferred Stock has the right to exchange the stated value, plus accrued and unpaid dividends, of the Series B Preferred Stock for any securities issued in a Subsequent Financing (as defined in the Series B Certificate of Designations), on a dollar-for-dollar basis, in lieu of any cash subscription payments therefor, which we refer to as the Series B Exchange Rights. The terms and conditions of the Series B Preferred Stock and the Series B Offering were reported in our Current Report on Form 8-K filed July 20, 2020, which is incorporated herein by reference.
 
On December 31, 2020, we entered into the Series C Purchase Agreement with a certain accredited investor, pursuant to which we agreed to sell in the Series C Registered Direct Offering 5,333.333 shares of our Series C Preferred Stock, at a price of $750 per share, which shares were initially convertible into an aggregate of 5,333,334 shares of Common Stock, at an initial stated value of $750.00 per share and a conversion price of $0.75 per share. The Series C Registered Direct Offering closed on January 6, 2021.
  
Concurrently with the Series C Registered Direct Offering, in the Series C Private Placement we also sold to the investor, an additional 5,333.333 shares of Series C Preferred Stock at the same price as the Series C Preferred Stock offered in the Series C Registered Direct Offering, which shares were initially convertible into an aggregate of 5,333,334 shares of our Common stock, together with warrants to purchase up to an aggregate of 10,666,668 shares of Common Stock, with an exercise price of $0.80 per share and an expiration term through July 6, 2026. The Series C Private Placement closed on January 6, 2021. The terms of the Series C Offerings were reported in our Current Reports on Form 8-K filed January 4, 2021, January 8, 2021 and January 13, 2021, which are incorporated herein by reference.
 
As a result of the Series C Offerings, pursuant to the Series B Certificate of Designation and the Series B Exchange Right, we are required to issue (in addition to shares of Series C Preferred Stock) Series B Exchange Warrants to purchase up to an additional 26,118,113 shares of Common Stock to any holders of Series B Preferred Stock who elect to exercise their Exchange Rights.  As of January 29, 2021, the shares of Series C Preferred Stock potentially issuable in relation to the Series B Exchange Rights would have been convertible into an aggregate of up to 676,811 incremental shares of Common Stock (beyond the 25,380,587 shares of Common Stock into which the underlying shares of Series B Preferred Stock, including accrued and unpaid dividends thereon, were convertible as of such date) at a conversion price of $0.75 per share, subject to certain limitations. In addition, as of January 29, 2021, the Series B Exchange Warrants potentially issuable in relation to the Series B Exchange Rights would have been exercisable for up to an aggregate of 26,057,398 additional shares of Common Stock, at an exercise price of $0.80 per share. In addition, this prospectus registers for resale, on behalf of the selling stockholders named herein, the shares of Common Stock underlying warrants potentially issuable pursuant to the Series B Exchange Right in respect of accrued or paid-in-kind dividend obligations relating to the Series B Preferred Stock. In accordance with applicable Commission guidance (Securities Act Forms Compliance and Disclosure Interpretations 116.13), this prospectus registers for resale, on behalf of the selling stockholders named herein, the shares of Common Stock issuable upon exercise of the Series B Exchange Warrants only.
 
Pursuant to the Series C Purchase Agreement, we must hold a meeting of our stockholders not later than March 31, 2021 to seek such approval as may be required from our stockholders (the “Stockholder Approval”), in accordance with applicable law, the applicable rules and regulations of the Nasdaq Stock Market, our certificate of incorporation and bylaws and the General Corporate Law of the State of Delaware. Until the Stockholder Approval has been obtained, the Series B Exchange Warrants held by the selling stockholders named herein may not be exercised for any shares of our Common Stock. We have scheduled a special meeting of our stockholders to be held on February 24, 2021, for the purpose of obtaining the Stockholder Approval. Please see our Definitive Proxy Statement filed on January 19, 2021.

USE OF PROCEEDS
 
The Common Stock to be offered and sold using this prospectus will be offered and sold by the selling stockholders named in this prospectus. Accordingly, we will not receive any proceeds from any sale of shares of our Common Stock in this offering. The shares of Common Stock covered by this prospectus may be issued upon exercise of the Series B Exchange Warrants. Upon any cash exercise of the warrants, the selling stockholders will pay us the applicable exercise price. The Placement Agent Warrants may be exercised and resold hereunder on a cashless basis, at the option of their holders, and we will not receive any proceeds upon such cashless exercise. We anticipate that proceeds that we receive from the cash exercise of such warrants, if any, will be used for working capital and general corporate purposes, including, without limitation, development of our product candidates, and general and administrative expenses. We will pay all of the fees and expenses incurred by us in connection with this registration. We will not be responsible for fees and expenses incurred by the selling stockholders or any underwriting discounts or agent’s commissions.

PLAN OF DISTRIBUTION
 
 Each selling stockholder and any of their pledgees, assignees and successors-in-interest may, from time to time, sell any or all of their shares of common stock covered hereby from time to time 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.
 
The selling stockholders also may resell all or a portion of the securities in open market transactions in reliance upon Rule 144 under the Securities Act, as permitted by that rule, or Section 4(1) under the Securities Act, if available, rather than under this prospectus, provided that they meet the criteria and conform to the requirements of those provisions 
 
Broker-dealers engaged by the selling stockholders may arrange for other brokers-dealers to participate in sales. If the selling stockholders effect such transactions by selling securities to or through underwriters, broker-dealers or agents, such underwriters, broker-dealers or agents may receive commissions in the form of discounts, concessions or commissions from the selling stockholders or commissions from purchasers of the securities for whom they may act as agent or to whom they may sell as principal. Such commissions will be in amounts to be negotiated, but, except as set forth in a supplement to this prospectus, in the case of an agency transaction will not be in excess of a customary brokerage commission in compliance with NASD Rule 2440; and in the case of a principal transaction a markup or markdown in compliance with NASD IM-2440.
 
In connection with the sale of the common stock or interests therein, the selling stockholders may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the common stock in the course of hedging the positions they assume. The selling stockholders may also sell shares of the common stock short and deliver these securities to close out their short positions, or loan or pledge the shares of common stock to broker-dealers that in turn may sell these securities. The selling stockholders may also enter into option or other transactions with broker-dealers or other financial institutions or create one or more derivative securities which require the delivery to such broker-dealer or other financial institution of shares offered by this prospectus, which shares such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).
 
The selling stockholders and any broker-dealers or agents that are involved in selling the shares may be deemed to be “underwriters” within the meaning of the Securities Act in connection with such sales. In such event, any commissions received by such broker-dealers or agents and any profit on the resale of the shares purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act. Each selling stockholder has informed us that it does not have any written or oral agreement or understanding, directly or indirectly, with any person to distribute their shares of common stock.
 
We are required to pay certain fees and expenses incurred by us incident to the registration of the shares. We have agreed to indemnify the selling stockholders against certain losses, claims, damages and liabilities, including liabilities under the Securities Act.
 
The selling stockholders will be subject to the prospectus delivery requirements of the Securities Act, including Rule 172 thereunder. The selling stockholders have advised us that there is no underwriter or coordinating broker acting in connection with the proposed sale of the resale shares by the selling stockholders.
 
 
 
-11-
We agreed to keep this prospectus effective until the earlier of (i) the date on which the shares may be resold by the selling stockholders without registration and without regard to any volume or manner-of-sale limitations by reason of Rule 144, without the requirement to be in compliance with the current public information under Rule 144 under the Securities Act, or any other rule of similar effect (assuming that the shares were at no time held by any affiliate of ours, and all warrants are exercised by “cashless exercise” as provided in each of the warrants) or (ii) all of the shares have been sold pursuant to this prospectus or Rule 144 under the Securities Act, or any other rule of similar effect. The resale shares will be sold only through registered or licensed brokers or dealers if required under applicable state securities laws. In addition, in certain states, the resale shares of common stock covered hereby may not be sold unless they have been registered or qualified for sale in the applicable state or an exemption from the registration or qualification requirement is available and is complied with.
 
Under applicable rules and regulations under the Exchange Act, any person engaged in the distribution of the resale shares may not simultaneously engage in market making activities with respect to the common stock for the applicable restricted period, as defined in Regulation M, prior to the commencement of the distribution. In addition, the selling stockholders will be subject to applicable provisions of the Exchange Act, and the rules and regulations thereunder, including Regulation M, which may limit the timing of purchases and sales of shares of the common stock by the selling stockholders or any other person. We will make copies of this prospectus available to the selling stockholders and have informed them of the need to deliver a copy of this prospectus to each purchaser at or prior to the time of the sale (including by compliance with Rule 172 under the Securities Act).

Series B Preferred Stock
 
On July 16, 2020, we designated 5,194.805195 shares as Series B Preferred Stock and issued 2,912.583005 of such shares.
 
Under the Series B Certificate of Designations, each share of Series B Preferred Stock will be convertible, at the holder’s option at any time, into Common Stock at a conversion rate equal to the quotient of (i) the $7,700 stated value (the “Series B Stated Value”) divided by (ii) the initial conversion price of $0.77, subject to specified adjustments for stock splits, cash or stock dividends, reorganizations, reclassifications other similar events as set forth in the Series B Certificate of Designations. In addition, if at any time after the six month anniversary of the date of the Private Placement, the closing sale price per share of Common Stock exceeds 250% of the initial conversion price, or $1.925, for 20 consecutive trading days, then all of the outstanding shares of Series B Preferred Stock will automatically convert (the “Automatic Conversion”) into such number of shares of Common Stock as is obtained by multiplying the number of shares of Series B Preferred Stock to be so converted, plus the amount of any accrued and unpaid dividends thereon, by the Series B Stated Value per share and dividing the result by the then applicable conversion price.
 
The Series B Preferred Stock contains limitations that prevent the holder thereof from acquiring shares of Common Stock upon conversion (including pursuant to the Automatic Conversion) that would result in the number of shares beneficially owned by such holder and its affiliates exceeding 9.99% of the total number of shares of Common Stock outstanding immediately after giving effect to the conversion, which percentage may be increased or decreased at the holder’s election not to exceed 19.99%.
 
Each holder of shares of Series B Preferred Stock, in preference and priority to the holders of all other classes or series of our stock, is entitled to receive dividends, commencing from the date of issuance. Such dividends may be paid by us only when, as and if declared by the Board, out of assets legally available therefore, semiannually in arrears on the last day of June and December in each year, commencing December 31, 2020, at the dividend rate of 9.0% per year, which is cumulative and continues to accrue on a daily basis whether or not declared and whether or not we have assets legally available therefore. We may pay such dividends at our sole option either in cash or in kind in additional shares of Series B Preferred Stock (rounded down to the nearest whole share), provided we must pay in cash the fair value of any such fractional shares in excess of $100.00. Under the Series B Certificate of Designations, to the extent that applicable law or any of our existing contractual restrictions prohibit any required issuance of additional shares of Series B Convertible Preferred Stock as in-kind dividends or otherwise (“Additional Shares”), then appropriate adjustment to the conversion price of the Series B Convertible Preferred Stock shall be made so that the resulting number of conversion shares includes the aggregate number of shares of Common Stock into which such Additional Shares would otherwise be convertible.
 
Under the Series B Certificate of Designations, each share of Series B Preferred Stock carries a liquidation preference equal to the Series B Stated Value (as adjusted thereunder) plus accrued and unpaid dividends thereon (the “Series B Liquidation Preference”).
 
In the event we effect any issuance of common stock or common stock equivalents for cash consideration, or a combination of units thereof (a “Subsequent Financing”), each holder of the Series B Preferred Stock has the right, subject to certain exceptions set forth in the Series B Certificate of Designations, at its option, to exchange (in lieu of cash subscription payments) all or some of the Series B Preferred Stock then held (with a value per share of Series B Preferred Stock equal to the Series B Liquidation Preference) for any securities or units issued in a Subsequent Financing on dollar-for-dollar basis.
 
The holders of the Series B Preferred Stock, voting as a separate class, will have customary consent rights with respect to certain corporate actions by us. We may not take the following actions without the prior consent of the holders of at least a majority of the Series B Preferred Stock then outstanding: (a) authorize, create, designate, establish, issue or sell an increased number of shares of Series B Preferred Stock or any other class or series of capital stock ranking senior to or on parity with the Series B Preferred Stock as to dividends or upon liquidation; (b) reclassify any shares of common stock or any other class or series of capital stock into shares having any preference or priority as to dividends or upon liquidation superior to or on parity with any such preference or priority of Series B Preferred Stock; (c) amend, alter or repeal our Certificate of Incorporation or Bylaws and the powers, preferences, privileges, relative, participating, optional and other special rights and qualifications, limitations and restrictions thereof, which would adversely affect any right, preference, privilege or voting power of the Series B Preferred Stock; (d) issue any indebtedness or debt security, other than trade accounts payable, insurance premium financings and/or letters of credit, performance bonds or other similar credit support incurred in the ordinary course of business, or amend, renew, increase, or otherwise alter in any material respect the terms of any such indebtedness existing as of the date of first issuance of shares of Series B Preferred Stock; (e) redeem, purchase, or otherwise acquire or pay or declare any dividend or other distribution on (or pay into or set aside for a sinking fund for any such purpose) any of our capital stock; (f) declare bankruptcy, dissolve, liquidate, or wind up our affairs; (g) effect, or enter into any agreement to effect, a Change of Control (as defined in the Series B Certificate of Designations); or (h) materially modify or change the nature of our business.

Warrants
 
Series B Exchange Warrants
 
The following is a summary of the material terms and provisions of the Series B Exchange Warrants. This summary is subject to and qualified in its entirety by the form of Series B Exchange Warrant.
 
The Series B Exchange Warrants will have an exercise price of $0.80 per share. The Series B Exchange Warrants will have a term of five and one-half years. The exercise price and number of shares of Common Stock issuable upon exercise are subject to appropriate adjustment in the event of share dividends, share splits, reorganizations or similar events affecting our shares of Common Stock. Series B Exchange Warrants will be issued in certificated form only. 
 
Until the Stockholder Approval is obtained, the Company may not issue any shares of Common Stock upon exercise of the Series B Exchange Warrants.
  
Following the Stockholder Approval, the Series B Exchange Warrants will be exercisable, at the option of each holder, in whole or in part, by delivering to us a duly executed exercise notice accompanied by payment in full for the number of shares of Common Stock purchased upon such exercise (except in the case of a cashless exercise as discussed below). A holder (together with its affiliates) may not exercise any portion of such holder’s Series B Exchange Warrants to the extent that the holder would own more than 4.99% (or, at the election of the purchaser, 9.99%) of our outstanding shares of Common Stock immediately after exercise, except that upon at least 61 days’ prior notice from the holder to us, the holder may increase the amount of ownership of outstanding shares of Common Stock after exercising the holder’s Series B Exchange Warrants up to 9.99% of the number of shares of Common Stock outstanding immediately after giving effect to the exercise, as such percentage ownership is determined in accordance with the terms of the Series B Exchange Warrants. 
 
If at the time of exercise of the Series B Exchange Warrant there is no effective registration statement registering, or the prospectus contained therein is not available for the resale of the shares of Common Stock issuable upon exercise of the Series B Exchange Warrant, then the Series B Exchange Warrants will also be exercisable on a “cashless exercise” basis under which the holder will receive upon such exercise a net number of common shares determined according to a formula set forth in the Series B Exchange Warrants. 
 
In the event of any fundamental transaction, as described in the  Series B Exchange Warrants and generally including any merger with or into another entity, sale of all or substantially all of our assets, tender offer or exchange offer, or reclassification of our shares of Common Stock, then upon any subsequent exercise of an Series B Exchange Warrant, the holder will have the right to receive as alternative consideration, for each share of Common Stock that would have been issuable upon such exercise immediately prior to the occurrence of such fundamental transaction, the number of shares of Common Stock of the successor or acquiring corporation or of our company, if it is the surviving corporation, and any additional consideration receivable upon or as a result of such transaction by a holder of the number of shares of Common Stock for which the Series B Exchange Warrant is exercisable immediately prior to such event. In addition, in the event of a fundamental transaction which is approved by our board of directors, the holder has the right to require us or a successor entity to redeem the Series B Exchange Warrant for cash in the amount of the Black-Scholes value of the unexercised portion of the Series B Exchange Warrant on the date of the consummation of the fundamental transaction. In the event of a fundamental transaction which is not approved by our Board, the holders of the Series B Exchange Warrants have the right to require us or a successor entity to redeem the Series B Exchange Warrant for the consideration paid in the fundamental transaction in the amount of the Black Scholes value of the unexercised portion of the Series B Exchange Warrant on the date of the consummation of the fundamental transaction. 
 
In accordance with its terms and subject to applicable laws, an Series B Exchange Warrant may be transferred at the option of the holder upon surrender of the Series B Exchange Warrant to us together with the appropriate instruments of transfer and payment of funds sufficient to pay any transfer taxes (if applicable). 
 
No fractional shares of Common Stock will be issued upon the exercise of the Series B Exchange Warrants. Rather, the number of shares of Common Stock to be issued will, at our election, either be rounded up to the nearest whole number or we will pay a cash adjustment in respect of such final fraction in an amount equal to such fraction multiplied by the exercise price.

There is no established trading market for the Series B Exchange Warrants, and we do not expect a market to develop. We do not intend to apply for a listing for the Series B Exchange Warrants on any securities exchange or other nationally recognized trading system. Without an active trading market, the liquidity of the Series B Exchange Warrants will be limited. 
 
Except as otherwise provided in the Series B Exchange Warrants or by virtue of the holders’ ownership of shares of Common Stock, the holders of Series B Exchange Warrants do not have the rights or privileges of holders of our shares of Common Stock, including any voting rights, until such Series B Exchange Warrant holders exercise their warrants.
 
An Series B Exchange Warrant may be modified or amended or the provisions thereof waived with the written consent of our company and the holder of the Series B Exchange Warrant.

Anti-Takeover Effects of Certain Provisions of Delaware Law and of Our 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.
 
 
-15-
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.

Item 15. Indemnification of Directors and Officers. 
 
Amended and Restated Bylaws
 
Pursuant to our bylaws, our directors and officers will be indemnified to the fullest extent allowed under the laws of the State of Delaware for their actions in their capacity as our directors and officers.
 
We must indemnify any person made a party to any threatened, pending, or completed action, suit, or proceeding, whether civil, criminal, administrative, or investigative (“Proceeding”) by reason of the fact that he is or was a director, against judgments, penalties, fines, settlements and reasonable expenses (including attorney’s fees) (“Expenses”) actually and reasonably incurred by him in connection with such Proceeding if: (a) he conducted himself in good faith, and: (i) in the case of conduct in his own official capacity with us, he reasonably believed his conduct to be in our best interests, or (ii) in all other cases, he reasonably believes his conduct to be at least not opposed to our best interests; and (b) in the case of any criminal Proceeding, he had no reasonable cause to believe his conduct was unlawful.
 
We must indemnify any person made a party to any Proceeding by or in the right of us, by reason of the fact that he is or was a director, against reasonable expenses actually incurred by him in connection with such proceeding if he conducted himself in good faith, and: (a) in the case of conduct in his official capacity with us, he reasonably believed his conduct to be in our best interests; or (b) in all other cases, he reasonably believed his conduct to be at least not opposed to our best interests; provided that no such indemnification may be made in respect of any proceeding in which such person shall have been adjudged to be liable to us.
 
No indemnification will be made by unless authorized in the specific case after a determination that indemnification of the director is permissible in the circumstances because he has met the applicable standard of conduct.
 
Reasonable expenses incurred by a director who is party to a proceeding may be paid or reimbursed by us in advance of the final disposition of such Proceeding in certain cases.
 
We have the power to purchase and maintain insurance on behalf of any person who is or was our director, officer, employee, or agent or is or was serving at our request as an officer, employee or agent of another corporation, partnership, joint venture, trust, other enterprise, or employee benefit plan against any liability asserted against him and incurred by him in any such capacity or arising out of his status as such, whether or not we would have the power to indemnify him against such liability under the provisions of the amended and restated bylaws.
 
 
 
II-1
Delaware Law
 
We are incorporated under the laws of the State of Delaware. Section 145 of the Delaware General Corporation Law provides that a Delaware corporation may indemnify any persons who are, or are threatened to be made, parties to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of such corporation), by reason of the fact that such person was an officer, director, employee or agent of such corporation, or is or was serving at the request of such person as an officer, director, employee or agent of another corporation or enterprise. The indemnity may include expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding, provided that such person acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the corporation’s best interests and, with respect to any criminal action or proceeding, had no reasonable cause to believe that his or her conduct was illegal. A Delaware corporation may indemnify any persons who are, or are threatened to be made, a party to any threatened, pending or completed action or suit by or in the right of the corporation by reason of the fact that such person was a director, officer, employee or agent of such corporation, or is or was serving at the request of such corporation as a director, officer, employee or agent of another corporation or enterprise. The indemnity may include expenses (including attorneys’ fees) actually and reasonably incurred by such person in connection with the defense or settlement of such action or suit provided such person acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the corporation’s best interests except that no indemnification is permitted without judicial approval if the officer or director is adjudged to be liable to the corporation. Where an officer or director is successful on the merits or otherwise in the defense of any action referred to above, the corporation must indemnify him or her against the expenses which such officer or director has actually and reasonably incurred. Our amended and restated certificate of incorporation and amended and restated bylaws provide for the indemnification of our directors and officers to the fullest extent permitted under the Delaware General Corporation Law.
 
Section 102(b)(7) of the Delaware General Corporation Law permits a corporation to provide in its certificate of incorporation that a director of the corporation shall not be personally liable to the corporation or its stockholders for monetary damages for breach of fiduciary duties as a director, except for liability for any:
 
transaction from which the director derives an improper personal benefit;
 
act or omission not in good faith or that involves intentional misconduct or a knowing violation of law;
 
unlawful payment of dividends or redemption of shares; or
 
breach of a director’s duty of loyalty to the corporation or its stockholders.
 
Our amended and restated certificate of incorporation and amended and restated bylaws include such a provision. Expenses incurred by any officer or director in defending any such action, suit or proceeding in advance of its final disposition shall be paid by us upon delivery to us of an undertaking, by or on behalf of such director or officer, to repay all amounts so advanced if it shall ultimately be determined that such director or officer is not entitled to be indemnified by us.
 
Section 174 of the Delaware General Corporation Law provides, among other things, that a director who willfully or negligently approves of an unlawful payment of dividends or an unlawful stock purchase or redemption may be held liable for such actions. A director who was either absent when the unlawful actions were approved, or dissented at the time, may avoid liability by causing his or her dissent to such actions to be entered in the books containing minutes of the meetings of the board of directors at the time such action occurred or immediately after such absent director receives notice of the unlawful acts.
 
Indemnification Agreements
 
As permitted by the Delaware General Corporation Law, we have entered, and intend to continue to enter, into separate indemnification agreements with each of our directors and executive officers, that require us to indemnify such persons against any and all expenses (including attorneys’ fees), witness fees, damages, judgments, fines, settlements and other amounts incurred (including expenses of a derivative action) in connection with any action, suit or proceeding, whether actual or threatened, to which any such person may be made a party by reason of the fact that such person is or was a director, an officer or an employee of us or any of our affiliated enterprises, provided that such person acted in good faith and in a manner such person reasonably believed to be in or not opposed to our best interests and, with respect to any criminal proceeding, had no reasonable cause to believe his or her conduct was unlawful. The indemnification agreements also set forth certain procedures that will apply in the event of a claim for indemnification thereunder.
 
 
II-2
At present, there is no pending litigation or proceeding involving any of our directors or executive officers as to which indemnification is required or permitted, and we are not aware of any threatened litigation or preceding that may result in a claim for indemnification.
 
We have an insurance policy covering our officers and directors with respect to certain liabilities, including liabilities arising under the Securities Act or otherwise.
 
Insofar as indemnification for liabilities arising under the Securities Act may be permitted to our directors, officers or controlling persons, we have been advised that in the opinion of the SEC this indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable.

Item 17.  Undertakings
 
The undersigned registrant hereby undertakes:
 
(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:
 
(a) To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933,
 
(b) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20 percent change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement,
 
(c) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement. 
 
 
 
II-3
Providedhowever, that paragraphs (1)(a), (1)(b) and (1)(c) above do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed with or furnished to the Commission by the registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.
 
(2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
 
(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.
 
(4) That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser:
 
(a) If the registrant is relying on Rule 430B:
 
(i) Each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and
 
(ii) Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for the purpose of providing the information required by section 10(a) of the Securities Act of 1933 shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.
 
(b) If the registrant is subject to Rule 430C, each prospectus filed pursuant to Rule 424(b) as part of a registration statement relating to an offering, other than registration statements relying on Rule 430B or other than prospectuses filed in reliance on Rule 430A, shall be deemed to be a part of and included in the registration statement as of the date it is first used after effectiveness. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such first use, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such date of first use.
 
 
II-4
(5) That, for the purpose of determining liability of the registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities, the registrant undertakes that in a primary offering of securities of the registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:
 
(a) Any preliminary prospectus or prospectus of the registrant relating to the offering required to be filed pursuant to Rule 424;
 
(b) Any free writing prospectus relating to the offering prepared by or on behalf of the registrant or used or referred to by the registrant;
 
(c) The portion of any other free writing prospectus relating to the offering containing material information about the registrant or its securities provided by or on behalf of the registrant; and
 
(d) Any other communication that is an offer in the offering made by a registrant to the purchaser.
 
(6) That, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
 
(7) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the forgoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.
