PROSPECTUS SUMMARY
 
This summary contains a general summary of the information contained in this prospectus. It is not complete, does not contain all of the information that you should consider before deciding whether to invest in our common stock, and may not include all the information that is important to you. You should read the entire prospectus and the documents incorporated by reference before making an investment decision.

Overview

We are a biopharmaceutical company focused on developing medicines for patients with neglected and rare diseases, with an ancillary focus on pediatric conditions, and on executing our Responsible Pricing Model in the commercialization of our products that may be approved. Our lead product candidate is benznidazole for the treatment of Chagas disease, a parasitic illness that can lead to long-term heart, intestinal and neurological problems. We are developing one of our proprietary monoclonal antibodies, lenzilumab (formerly known as KB003), for the treatment of chronic myelomonocytic leukemia, or CMML, and potentially for the treatment of juvenile myelomonocytic leukemia, or JMML, both of which are rare hematologic cancers with high unmet medical need. We are exploring partnering opportunities to enable development of ifabotuzumab (another of our proprietary monoclonal antibodies, formerly known as KB004), for the potential treatment of serious pulmonary conditions and certain rare solid and hematologic cancers and KB001-A which was being developed for the treatment of lung infections related to cystic fibrosis.  With a focus on neglected, rare and orphan diseases, we believe we have the opportunity to benefit from various regulatory incentives, such as orphan drug exclusivity, breakthrough therapy designation, fast track designation, accelerated approval, priority review and priority review vouchers, or PRVs, where available, that provide for certain periods of exclusivity, expedited review and/or other benefits.

Upon approval of any of our products, we intend to apply our Responsible Pricing Model, which focuses on affordability for patients and payers, transparency for all stakeholders, and delivery of a reasonable return in recognition of the risks we are taking in our development efforts.

Information Related to this Offering

These shares of common stock being offered pursuant to this prospectus consist of: (i) 7,147,035 shares issued in a private placement pursuant to that certain Securities Purchase Agreement, dated April 1, 2016; and (ii) 200,000 shares issuable upon the exercise of a common stock purchase warrant issued on June 30, 2016, pursuant to that certain Agreement for Manufacture, Development and Commercialization of Benznidazole for Human Use, or the MDC Agreement, between us and Savant Neglected Diseases, LLC, or Savant. Collectively, we refer herein to the shares issued or issuable pursuant to these agreements as the Shares.  The Shares and the common stock purchase warrant were initially sold in reliance on exemptions from registration under the Securities Act of 1933, as amended, or the Securities Act.

The Exit Financing

On April 1, 2016, we entered into a Securities Purchase Agreement that provided for our issuance of shares of our common stock in respect of exit financing to enable us to emerge from bankruptcy. The exit financing transaction closed on June 30, 2016, and we issued to the purchasers an aggregate of 7,147,035 shares of common stock for an aggregate purchase price of $11.0 million.

The MDC Agreement

On June 30, 2016, we entered into the MDC Agreement with Savant, pursuant to which we acquired certain worldwide rights relating to benznidazole.  Also pursuant to the MDC Agreement, we issued to Savant a five-year warrant to purchase up to 200,000 shares of common stock at a per share price of $2.25, exercisable for 25% of the shares immediately and exercisable for the remaining shares upon reaching certain milestones related to the regulatory approval of benznidazole.

RISK FACTORS
 
Investing in our securities involves a high degree of risk. You should carefully consider and evaluate the risks and uncertainties described in Part I, Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2016 and subsequently filed SEC reports, which are incorporated by reference herein, together with the other information set forth or incorporated by reference in this prospectus and any accompanying prospectus supplement, before you decide to purchase our securities. Any of the risks and uncertainties set forth herein or therein could materially and adversely affect our business, results of operations and financial condition, which in turn could materially and adversely affect the trading price or value of our securities. As a result, you could lose all or part of your investment.

The risks described in these documents are not the only ones we face. There may be other unknown or unpredictable economic, business, competitive, regulatory or other factors that could have material adverse effects on our future results. Please also read carefully the section below entitled “Cautionary Note Regarding Forward-Looking Statements.”

 
CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS
 
This prospectus contains statements that discuss future events or expectations, projections of results of operations or financial condition, trends in our business, business prospects and strategies and other “forward-looking” information. In some cases, you can identify “forward-looking statements” by words like “may,” “will,” “should,” “expects,” “plans,” “anticipates,” “believes,” “estimates,” “predicts,” “intends,” “potential” or “continue” or the negative of those words and other comparable words. These statements may relate to, among other things, our expectations regarding the scope, progress, expansion, and costs of researching, developing and commercializing our product candidates; our intent to in-license or acquire additional product candidates; our opportunity to benefit from various regulatory incentives and the application of our Responsible Pricing Model; expectations for our financial results, revenue, operating expenses and other financial measures in future periods; and the adequacy of our sources of liquidity to satisfy our working capital needs, capital expenditures, and other liquidity requirements. Actual events or results may differ materially due to known and unknown risks, uncertainties and other factors such as:
 
·
our lack of revenues, history of operating losses, limited cash reserves and ability to obtain additional capital to develop and commercialize our product candidates, including the additional capital which will be necessary to complete the clinical trials that we have initiated or plan to initiate, and continue as a going concern;
 
·
our ability to execute our strategy and business plan;
 
·
our ability to list our common stock on a national securities exchange, whether through a new listing or by completing a reverse merger or other strategic transaction;
 
·
the success, progress, timing and costs of our efforts to evaluate or consummate various strategic alternatives if in the best interests of our stockholders;
 
·
the availability of a 505(b)(2) development pathway for the potential approval by FDA of our benznidazole candidate as a treatment for Chagas disease remaining acceptable to FDA in the future;
 
·
the fact that a 505(b)(2) pathway does not assure a product candidate will be deemed safe or effective, or that FDA approval will be obtained;
 
·
the requirement that we be first to receive FDA approval for benznidazole as a treatment for Chagas disease as a prerequisite to our ability to apply for or receive a Priority Review Voucher in respect of that candidate;
 
·
the potential timing and outcomes of clinical studies of benznidazole, lenzilumab, ifabotuzumab or any other product candidates and the uncertainties inherent in clinical testing;
 
·
the commercial viability of our proposed drug pricing program;
 
 
·
our ability to timely source adequate supply of our development products from third-party manufacturers on which we depend;
 
·
the potential, if any, for future development of any of our present or future products;
 
·
our ability to successfully progress, partner or complete further development of our programs;
 
·
our ability to identify and develop additional products;
 
·
our ability to attain market exclusivity or to protect our intellectual property;
 
·
competition; and
 
·
changes in the regulatory landscape that may prevent us from pursuing or realizing any of the expected benefits from the various regulatory incentives at the center of our strategy, or the imposition of regulations that affect our products.
 
These are only some of the factors that may affect the forward-looking statements contained in this prospectus. For a discussion identifying additional important factors that could cause actual results to vary materially from those anticipated in the forward-looking statements, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and “Risk Factors” in our 2016 Annual Report on Form 10-K. You should review these risk factors for a more complete understanding of the risks associated with an investment in our securities. However, we operate in a competitive and rapidly changing environment and new risks and uncertainties emerge, are identified or become apparent from time to time. It is not possible for us to predict all risks and uncertainties that could have an impact on the forward-looking statements contained in this annual report. You should be aware that the forward-looking statements contained in this annual report are based on our current views and assumptions. We undertake no obligation to revise or update any forward-looking statements made in this prospectus to reflect events or circumstances after the date hereof or to reflect new information or the occurrence of unanticipated events, except as required by law. The forward-looking statements in this prospectus are intended to be subject to protection afforded by the safe harbor for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995.
 
 
SELLING STOCKHOLDERS
 
The Shares being registered by resale pursuant to this prospectus were issued, or became issuable, in connection with the respective transactions described above under “Prospectus Summary -– Information Related to this Offering”. This prospectus is being filed pursuant to our obligations to each of the selling stockholders in connection with these transactions.

The following table sets forth, to our knowledge, certain information about the selling stockholders. The percentage of outstanding shares of common stock beneficially owned before the offering is based on 14,977,397 shares of common stock outstanding as of March 14, 2017. The number and percentage of outstanding shares of common stock beneficially owned after the offering listed in the table below assumes, in the case of Savant, the cash exercise of the warrant for all of the underlying shares, that all of the shares of our common stock (including, in the case of Savant, all shares issuable upon the exercise of the common stock purchase warrant issued to Savant) being offered by the selling stockholders are sold and that no additional shares of our common stock are purchased by the selling stockholders prior to the completion of this offering.

The selling stockholders may offer from time to time all or some or none of their shares of common stock under this prospectus. We do not know how long the selling stockholders will hold the shares before selling them, if ever, and we currently have no agreements, arrangements or understandings with the selling stockholders regarding the sale or other disposition of any of the shares.  The selling stockholders are not making any representation that any shares covered by this prospectus will be offered for sale.

The information set forth below is based on information obtained from the selling stockholders and on information in our possession regarding the issuance of the shares and the warrant. Except as otherwise indicated in the footnotes below, based on representations made to us by the selling stockholders, none of the selling stockholders has or within the past three years has had, any position, office or other material relationship with us or any of our affiliates other than as a result of the selling stockholders' beneficial ownership of our common stock. To our knowledge, none of the selling stockholders are broker-dealers or affiliates of broker-dealers, nor at the time of the acquisition, did any selling stockholder have direct or indirect agreements or understandings with any person to distribute its shares or, in the case of Savant, its warrant. Information about the selling stockholders may change from time to time. Any changed information will be set forth in prospectus supplements, if required by applicable law.

(1)           Beneficial ownership is determined in accordance with the rules of the SEC and generally includes voting and/or investment power with respect to securities. In computing the number of shares beneficially owned by a person and the percentage ownership of that person, securities that are currently convertible or exercisable into shares of our common stock, or convertible or exercisable into shares of our common stock within 60 days of the date hereof are deemed outstanding.  Such shares, however, are not deemed outstanding for the purpose of computing the percentage ownership of any other person. Except as indicated in the footnotes to the following table, each stockholder named in the table has sole voting and investment power with respect to the shares set forth opposite such stockholder’s name.

(2)           Assumes that all securities registered will be sold.

Dr. Chappell is the managing member of BH Management, which is the managing member of BHC and the controlling person of BHCMF. By virtue of these relationships, each of BH Management and Dr. Chappell may be deemed to beneficially own the Shares owned directly by each of BHC and Cheval and Dr. Chappell may be deemed to beneficially own the Shares owned directly by BHCMF. In addition to these shares, Dr. Chappell also has beneficial ownership of 25,000 shares of common stock that may be issued upon exercise of an option within 60 days of March 14, 2017. Dr. Chappell serves on our board of directors.

The warrant was exercisable for 25% of the shares immediately upon issuance and is exercisable for the remaining shares upon reaching certain milestones related to regulatory approval of benznidazole.  All of the shares issuable upon exercise of the warrant are subject to registration rights.
 
 
DETERMINATION OF MARKET PRICE
 
The selling stockholders will determine at what price they may sell the offered shares, and such sales may be made at prevailing market prices or at privately negotiated prices. See “Plan of Distribution” below for more information.
 
USE OF PROCEEDS
 
We will not receive any of the proceeds from any sale or other disposition of the common stock covered by this prospectus. The selling stockholders will receive all of the proceeds from this offering.

We will receive proceeds upon the cash exercise of the warrant for which the underlying warrant shares are being registered hereunder. Assuming full cash exercise of the warrant at the exercise prices specified therein, and assuming no further adjustments to the exercise prices, we would receive gross proceeds of $450,000. We intend to use any net proceeds from any exercise of the warrant for operating costs, working capital, and general corporate purposes. The amount and timing of our actual use of proceeds may vary significantly depending upon numerous factors, including the actual amount of proceeds we receive and the timing of when we receive such proceeds. There is no guarantee that the warrant will be exercised, or that the warrant will be exercised for cash or in full. The terms of the warrant provides that it may be exercised on a cashless basis if, at the time of exercise there is no effective registration statement registering, or no current prospectus available for, the resale or other disposition of the underlying shares by the warrantholder or its transferee and provided that the warrantholder or such transferee has cooperated with our reasonable requests in connection with our efforts to register such resale or other disposition. We will not receive any cash proceeds as a result of any portion of the warrant that is exercised on a cashless basis. The exercise price and number of shares underlying the warrant may be adjusted in certain circumstances, including subdivisions and stock splits, stock dividends, combinations, reorganizations, reclassifications, consolidations, mergers or sales of properties and assets and upon the issuance of certain assets or securities to holders of our common stock, as applicable.
 
 
PLAN OF DISTRIBUTION
 
We are registering the shares of common stock on behalf of the selling stockholders. The selling stockholders will act independently of us in making decisions with respect to the timing, manner and size of each sale. The selling stockholders may, from time to time, sell any or all of their shares of common stock on any stock exchange, market or trading facility on which the shares are traded or in private transactions. These sales may be at fixed or negotiated prices. The selling stockholders may use any one or more of the following methods when selling shares:

·
ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;
 
·
block trades in which the broker-dealer will attempt to sell the shares as agent but may position and resell a portion of the block as principal to facilitate the transaction;
 
·
purchases by a broker-dealer as principal and resale by the broker-dealer for its account;
 
·
transactions through a broker-dealer in which the broker-dealer agrees with a selling stockholder to sell a specified number of shares at a stipulated price per share;
 
·
privately negotiated transactions;
 
·
exchange distributions in accordance with the rules of the applicable exchange;
 
·
short sales;
 
·
through the writing or settlement of options or other hedging transactions, whether through an options exchange or otherwise;
 
·
a combination of any such methods of sale; and
 
·
any other method permitted pursuant to applicable law.
 
Broker-dealers engaged by the selling stockholders may arrange for other broker-dealers to participate in sales. Broker-dealers may receive commissions or discounts from the selling stockholders (or, if any broker-dealer acts as agent for the purchaser of shares, from the purchaser) in amounts to be negotiated. The selling stockholders do not expect these commissions and discounts to exceed what is customary in the types of transactions involved. Any profits on the resale of shares of common stock by a broker-dealer acting as principal might be deemed to be underwriting discounts or commissions under the Securities Act. Discounts, concessions, commissions and similar selling expenses, if any, attributable to the sale of shares will be borne by a selling stockholder. The selling stockholders may agree to indemnify any agent, dealer or broker-dealer that participates in transactions involving sales of the shares if liabilities are imposed on that person under the Securities Act.

We are not aware of any written or oral agreement or understanding that the selling stockholders have entered into with any person to distribute shares of our common stock covered hereby. 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.  If the selling stockholders use this prospectus supplement and accompanying prospectus for any sale of the shares of common stock, they will be subject to the prospectus delivery requirements of the Securities Act.

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 its short positions, or loan or pledge the 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 the creation of 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 also may transfer the shares of common stock in other circumstances, in which case the transferees or other successors in interest will be the selling beneficial owners for purposes of this prospectus supplement and accompanying prospectus and may sell the shares of common stock from time to time under this prospectus supplement and accompanying prospectus after we have filed an amendment to this prospectus supplement under an applicable provision of the Securities Act supplementing or amending the list of selling stockholders to include the transferee or other successors in interest as selling stockholders under this prospectus supplement.

The selling stockholders and any other person participating in a distribution will be subject to the Exchange Act. The Exchange Act rules include, without limitation, Regulation M, which may limit the timing of purchases and sales of shares of our common stock by the selling stockholders and any such other person. In addition, Regulation M of the Exchange Act may restrict sales activity by a person engaged in the distribution of the shares for a period of up to five business days prior to the commencement of such distribution. This may affect the marketability of the shares of our common stock and the ability of any person or entity to engage in market-making activities with respect to shares of our common stock. We have informed the selling stockholders that the anti-manipulative provisions of Regulation M may apply to their sales in the market.

We will not receive any of the proceeds from this offering. We are required to pay certain fees and expenses incurred by us incident to this registration statement and the registration of the shares generally. We have agreed to indemnify the selling stockholders against certain losses, claims, damages and liabilities, including liabilities under the Securities Act and other securities laws.

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

We do not assure you that the selling stockholders will sell any or all of the shares offered by them pursuant to this prospectus. In addition, we do not assure you that the selling stockholders will not transfer, devise or gift the shares by other means not described in this prospectus. Moreover, any shares of common stock covered by this prospectus that qualify for sale pursuant to Rule 144 may be sold under Rule 144 rather than pursuant to this prospectus.

We may suspend the use of this prospectus if we learn of any event that causes this prospectus to include an untrue statement of a material fact or omit to state a material fact required to be stated in this prospectus or necessary to make the statements in this prospectus not misleading in light of the circumstances then existing. If this type of event occurs, a prospectus supplement or post-effective amendment, if required, will be distributed to each selling stockholder.

ITEM 14.  INDEMNIFICATION OF OFFICERS AND DIRECTORS
 
Section 102(b)(7) of the Delaware General Corporation Law, or the DGCL, provides that a Delaware corporation, in its certificate of incorporation, may limit the personal liability of a director 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 derived an improper personal benefit;
 
·
act or omission not in good faith or that involved intentional misconduct or a knowing violation of law;
 
·
unlawful payment of dividends or redemption of shares; or
 
·
breach of the director’s duty of loyalty to the corporation or its stockholders.
 
           Section 145(a) of the DGCL provides, in general, that a Delaware corporation may indemnify any person who was or is a party, or is threatened to be made a party, 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 the corporation) because that person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation or other enterprise. The indemnity may include expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by the person in connection with such action, so long as the person acted in good faith and in a manner he or she reasonably believed was in or not opposed to the corporation’s best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful.
 
Section 145(b) of the DGCL provides, in general, that a Delaware corporation may indemnify any person who was or is a party, or is threatened to be made a party, to any threatened, pending or completed action or suit by or in the right of the corporation to obtain a judgment in its favor because the person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation or other enterprise. The indemnity may include expenses (including attorneys’ fees) actually and reasonably incurred by the person in connection with the defense or settlement of such action, so long as the person acted in good faith and in a manner the person reasonably believed was in or not opposed to the corporation’s best interests, except that no indemnification shall be permitted without judicial approval if a court has determined that the person is to be liable to the corporation with respect to such claim. Section 145(c) of the DGCL further provides that, if a present or former director or officer has been successful in defense of any action referred to above, the corporation must indemnify such officer or director against the expenses (including attorneys’ fees) he or she actually and reasonably incurred in connection with such action.
 
 
Section 145(g) of the DGCL provides, in general, that a corporation may purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation or other enterprise against any liability asserted against and incurred by such person, in any such capacity, or arising out of his or her status as such, whether or not the corporation could indemnify the person against such liability under Section 145 of the DGCL.
 
Our Amended and Restated Certificate of Incorporation eliminates the personal liability of our directors to the Company or our stockholders for monetary damages for breach of fiduciary duty as a director, with certain limited exceptions set forth therein. Our Amended and Restated Bylaws provide for the indemnification of or directors and officers to the fullest extent permitted by the DGCL.
 
We maintain an insurance policy that covers certain liabilities of our directors and officers arising out of claims based on acts or omissions in their capacities as directors or officers.

Certain of our non-employee directors may, through their relationships with their employers, also be insured and/or indemnified against certain liabilities incurred in their capacity as members of our board of directors.
 
The foregoing descriptions are only general summaries.
 
ITEM 15.  RECENT SALES OF UNREGISTERED SECURITIES

Since March 17, 2014, we have sold the following securities that were not registered under the Securities Act:

(a)
On November 18, 2015, Armistice Capital Fund, or Armistice, advised us that it was prepared to provide an immediate equity infusion if we needed it to fund operations. We elected not to accept such financing, but determined that it was appropriate to compensate Armistice for its willingness to provide such financing and on December 4, 2015, issued a warrant to Armistice to purchase up to an aggregate of 125,000 shares of our common stock at an exercise price of $29.32 per share.

(b)
On December 15, 2015, we issued 326,698 shares of common stock to certain investors in a private placement, or the PIPE Offering, for an aggregate purchase price of $8.2 million.

(c)
On April 1, 2016, we entered into a Securities Purchase Agreement, or the Exit Financing SPA, which provided for the sale of an aggregate of 5,885,000 shares of our common stock, subject to adjustment as provided in the Exit Financing SPA, in respect of exit financing to enable us to emerge from bankruptcy. The exit financing closed on June 30, 2016, and we issued to the purchasers an aggregate of 7,147,035 shares of common stock for an aggregate purchase price of $11.0 million.

(d)
On June 30, 2016, we entered into the MDC Agreement with Savant Neglected Diseases, LLC, or Savant, pursuant to which we acquired certain worldwide rights relating to benznidazole and issued to Savant a five-year warrant to purchase up to 200,000 shares of Common Stock at a per share price of $2.25, exercisable for 25% of the shares immediately and exercisable for the remaining shares upon reaching certain milestones related to the regulatory approval of benznidazole.

(e)
On June 30, 2016, our Second Amended Plan of Reorganization, dated May 9, 2016, as amended, or the Plan, became effective and we emerged from our Chapter 11 bankruptcy proceedings. In connection with our emergence from bankruptcy, we issued shares of common stock in satisfaction of certain claims or interests in the Company as follows:

1.
We issued 2,350,480 shares to certain lenders in satisfaction of amounts owed by us under a Debtor in Possession Credit and Security Agreement with the lenders.

2.
We issued 327,608 shares of common stock to the plaintiffs in litigation related to the PIPE Offering in accordance with a settlement stipulation between us and the plaintiffs.
 
 
3.
We issued 3,750 shares to a former director in satisfaction of claims made by the former director against us.

4.
We issued 300,000 shares of common stock to certain investors in satisfaction of claims made by plaintiffs in class action litigation related to the events surrounding our former chairman and chief executive officer.

5.
We issued promissory notes in an aggregate principal amount of approximately $1.2 million to certain holders of allowed general unsecured claims in our bankruptcy proceedings. These notes are unsecured, bear interest at a rate of 10% per annum and mature on June 30, 2019.

6.
In accordance with the Plan, we issued an aggregate 323,155 shares of common stock in connection with a one-time equity award to each of our chairman and chief executive officer Cameron Durrant, M.D., director Ronald Barliant and former director David Moradi.

(f)
On November 7, 2016, we issued 25,000 shares of restricted common stock to MZHCI, an investor relations consultant. The shares are subject to a six month restriction. The fair value of the shares issued based on the closing price on November 7, 2016 was $77,500.

(g)
On November 15, 2016, we issued 40,000 shares of restricted common stock to Batuta Capital Advisors LLC, a financial advisor in return for services.

(h)
On December 1, 2016, we issued a warrant to Caribbean Consulting Partners, LLC to purchase up to an aggregate of 25,000 shares of common stock at an exercise price of $4.00 per share. The warrant expires on the one year anniversary of its issuance and had a fair value of approximately $40,000. The warrant provides that if we declare a dividend, or makes any other distribution of its assets, to holders of common stock, then the warrant holder shall be entitled to participate in such dividend or distribution to the same extent that the holder would have participated had it held the number of shares of common stock acquirable upon complete exercise of the warrant. The warrant was issued in connection with the engagement agreement related to certain investor relations activities.


The sales and issuances described in paragraphs (a), (b) and (f), (g) and (h) were made in reliance on the exemptions from registration provided by Section 4(a)(2) of the Securities Act as transactions not involving a public offering and/or Regulation D under the Securities Act as sales to accredited investors. The purchasers in these transactions represented to us that they were accredited investors and were acquiring the shares for investment purposes and not with a view to, or for sale in connection with, any distribution thereof.

The sales and issuances described in paragraphs (c) through (e) were made in reliance on the exemptions from registration provided by Section 4(a)(2) of the Securities Act as transactions not involving a public offering, Regulation D under the Securities Act as sales to accredited investors, and/or Section 1145 of the U.S. Bankruptcy Code as issuances of securities under a bankruptcy plan in exchange for a claim against the debtor.

(a) Exhibits

ITEM 17.  UNDERTAKINGS
 
(a)
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:
 
(i)   To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;
 
(ii)  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 Securities and Exchange Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and
 
(iii) 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;
 
providedhowever, that paragraphs (a)(1)(i), (a)(1)(ii), and (a)(1)(iii) above do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Securities and Exchange Commission by the registrant pursuant to Section 13 or Section 15(d) of the Exchange Act 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 a 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 herein, 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.
 
(5) That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser, 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 (§230.430A of this chapter), shall be deemed to be 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.

(b) The undersigned registrant hereby undertakes 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 section 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. 
 
 
(h) 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 foregoing 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.
