Any representation to the contrary is a criminal offense. The date of this prospectus is June ___, 1999 Prospectus Summary Because this is a summary, it may not contain all information that may be important to you. You should read this entire prospectus, including the information incorporated by reference and the financial data and related notes, before making an investment decision. When used in this prospectus, the terms "we," "our" and "us" refer to Hemispherx and not to the selling stockholders. Hemispherx Hemispherx is a pharmaceutical company that is using genetic technologies to develop therapeutic products for the treatment of viral diseases and certain cancers. Ampligen, our lead compound, is in advanced human clinical development for various therapeutic indications. We have clinically evaluated Ampligen in over 350 patients for different therapeutic indications. These clinical studies show that the drug acts as an antiviral agent against a large number of different viruses, including myalgic encephalomyelitis, also known as chronic fatigue syndrome, HIV infection and hepatitis B, as well as a treatment for certain cancers. Clinical trials conducted in the early 1990's indicate that Ampligen may have potential in the treatment of metastatic renal cell cancer and malignant melanoma. Ampligen appears to stimulate the immune system and is generally well tolerated. We are currently conducting Phase III human clinical trials for the therapeutic treatment of chronic fatigue syndrome. Phase III trials are the final drug testing phase for approval by the U.S. Food and Drug Administration. We will continue our research and clinical efforts for the next several years. We expect significant benefits as a result of certain revenues expected from various cost recovery treatment programs, notably in Canada, Belgium and the United States. Cost recovery treatment programs allow us to charge patients for the cost of Ampligen even though the drug has yet to be approved by the Food and Drug Administration. We are also pursuing similar programs in other countries, especially within the European Union where our resources have been substantially increased in order to pursue regulatory approvals. Over the years, we have secured more than 25 issued U.S. patents and over 300 derivative international filings. Nine additional U.S. patent filings are pending along with their international counterparts. We require substantial resources to conduct the time-consuming research, preclinical development, and clinical trials necessary to bring pharmaceutical products to market and establish commercial production and marketing capabilities. Accordingly, we may need to raise additional funds through additional equity or debt financing, collaborative arrangements with corporate partners, off balance sheet financing or from other sources in order to complete the necessary clinical trials and the regulatory approval processes and begin commercializing our products. 2 Manufacturing In 1994, we entered into an agreement with Bioclones, Ltd., a subsidiary of South African Breweries, Ltd., to co-develop various genetic drugs, including Ampligen. The Bioclones agreement provided for the formation of Ribotech, Ltd. Ribotech was formed in 1994 to produce the raw materials for manufacturing Ampligen. Hemispherx and Bioclones jointly own Ribotech. Ribotech presently has the capacity to produce the materials required to treat approximately 2,000 patients per year. We are planning to develop a new production plant. This facility will have the capacity to produce the materials needed to treat up to 50,000 patients. In the third quarter of 1998, we informed the Food and Drug Administration of our intention to switch certain patients from the labor intensive freeze-dried dosage form of Ampligen to the more convenient ready-to-infuse liquid formulation for the treatment of patients in clinical trials. We manufacture the liquid product more efficiently and the process allows greater production volumes, although we will continue to produce the freeze-dried product for further clinical development. We have initiated efforts to identify and locate additional liquid formulation capacity in the U.S. and Europe, since we anticipate that additional production capacity will be needed in the future. Product Development In the second quarter of 1998, we commenced a Phase III clinical study of Ampligen for the treatment of chronic fatigue syndrome. We plan to enroll up to 230 patients with severely debilitating chronic fatigue syndrome. Chronic fatigue syndrome patients who are not eligible for the Phase III trial in the United States may seek treatment under the chronic fatigue syndrome cost recovery treatment program now authorized by the Food and Drug Administration. Treatment with cost recovery has been ongoing since mid-1997 under the auspices of the Food and Drug Administration. Under this protocol, the enrolled patients pay for the Ampligen administered, which totals about $7,000 for a 24 week treatment course. Patients are also treated for chronic fatigue syndrome in Belgium, Austria and Canada under similar chronic fatigue cost recovery treatment programs. Distribution/Marketing In February 1998, we entered into an agreement with Kimberly Home Health Care, Inc. which operates under the name Olsten Health Services. Olsten Health Services will serve as a distributor of our products to U.S. patients enrolled in the chronic fatigue syndrome cost recovery program and will maintain an Ampligen inventory for use in treating these patients. In addition, Olsten Health Services will initially provide up to $500,000 of support for other clinical program efforts including identification of the potential medical and economic benefits 3 to patients receiving Ampligen. Olsten Health Services is able to deliver treatment and services to chronic disease patients including infusion services, home nursing and other medical services through a national network of more than 500 locations. We are also exploring distribution and marketing relationships for the Western European market. We formed a wholly owned subsidiary in Europe, Hemispherx Biopharma Europe NV/SA. This subsidiary is presently based in Antwerp and is pursuing chronic fatigue clinical tests, related clinical treatments and new drug marketing approval in Belgium and other European countries. In December 1998, we filed final drug marketing approval documents for the European Union, consisting of 15 countries, for Ampligen's use for treatment of patients with chronic fatigue syndrome. In January 1999, we were notified that the filing was complete and the review process had started. Recent Developments Subsidiary Spin-Off We are considering distributing to our shareholders at least 80% of the issued and outstanding shares of common stock of Core Biotech Corp. We would distribute the Core Biotech shares to each of the holders of our common stock as of a record date set by us. The timetable for this potential spin-off has not been determined. After the proposed spin-off, Core Biotech would use genetic technologies, including Ampligen and other products, to develop therapeutic products for the treatment of viral hepatitis diseases. We would license or sublicense to Core Biotech the technology for the products that will be used by Core Biotech. In connection with the proposed spin-off, we would enter into several agreements with Core Biotech, including, but not limited to, (a) a separation and distribution agreement which will separate our hepatitis technology from us, including some assets and liabilities, and distribute Core Biotech common stock to our shareholders; (b) a tax allocation agreement allocating tax liabilities that relate to the planned spin-off and to periods prior to the spin-off date; (c) a services agreement providing for allocation of responsibilities with respect to various services to be provided by us to Core Biotech; (d) an employee benefits agreement; (e) a technology license agreement; and 4 (f) a research and development agreement. These agreements are in the early stages of development and no final determination as to structure has been made. Accordingly, we have not determined Core Biotech's capitalization, pro forma financial information, management or inter-company transactions. We believe that, except for the initial capitalization of Core Biotech, the transfer of any other assets and liabilities would have no significant affect on our financial position. The initial capitalization could be up to $5,000,000 and could negatively effect the amount of cash we have at the time of the spin-off. The results of operations for Core Biotech were not significant for the year ended December 31, 1998. Litigation On September 14, 1998, VMW, Inc. filed a complaint against us in the United States District Court, Southern District of New York. The complaint alleges that we failed to fulfill our financial obligations to VMW, Inc. with respect to a certain letter agreement pertaining to marketing services rendered. VMW, Inc. claims damages of less than $100,000. We counterclaimed alleging breach of contract by VMW and have demanded damages of approximately $25,000. The parties have entered into a settlement agreement dated May 7, 1999. The settlement provides that we pay $20,000 and deliver 7,111 shares of our common stock to VMW. The common stock has certain registration rights and the settlement provides for conditions upon which additional shares of common stock may be issued to VMW. The case will be dismissed when we file the settlement agreement with the Court. Ell and Co., and the Northern Trust Company, as Trustee of the AT&T Master Pension Trust filed a complaint against us in the Court of Chancery of the State of Delaware in and for New Castle County on September 23, 1998. This complaint alleges that we breached our contractual obligations as set forth in our Certificate of Powers, Designations, Preferences and Rights of the Series E Convertible Stock. The plaintiff seeks to enforce its rights to convert 1,500 shares of Series E Preferred Stock into 750,000 shares of freely traded common stock and to recover damages for its inability to convert the preferred stock when it requested to do so. We do not believe that the complaint will have a material effect on our results of operations or our financial position. Although we maintain that the 1,500 shares of Series E Preferred Stock had been properly redeemed and, therefore, the plaintiff was not contractually able to effect a proper conversion into common shares, we agreed, in December 1998, to convert the plaintiff's preferred stock into common stock. Currently, the claim is still in litigation. We filed a complaint against Manual P. Asensio, Asensio and Company, Inc. and others in the United States District Court for the Eastern District of Pennsylvania on September 5 30, 1998. We allege the unlawful manipulation and short selling by defendants of our common stock on the American Stock Exchange on or about September 15, 1998 through the present. We allege, among other things, that the defendants distributed materially false information concerning us to the public, thereby damaging us and our shareholder equity. Certain of the defendants have entered motions to dismiss all or part of the case. On March 12, 1999, the Court issued a memorandum decision dismissing four of the six counts on jurisdictional grounds. Currently, the case is in the discovery phase. The Offering Selling Stockholder Agreement Each selling stockholder has entered into an agreement with us whereby, for a period of one year from the date of this prospectus, we, or an agent designated by us, may purchase and sell that selling stockholder's warrants and the shares of common stock underlying their warrants on a "best efforts" basis at prices set by that selling stockholder. The purchase price set by each selling stockholder shall be discounted 10%, representing the commission to the agent so designated by us. We will not receive any commission on any sales by us of the selling stockholders' securities. After the expiration of the one year period, the selling stockholders may sell their securities from time to time in one or more transactions on the American Stock Exchange, in foreign markets, special offerings, exchange distributions, secondary distributions, negotiated transactions, or a combination of these transactions. The agreement also provides that should the market price of our common stock exceed 10% of the sum of the exercise price of the warrant and the price set by the selling stockholder for ten consecutive trading days as reported on the American Stock Exchange, we will be obligated to purchase or arrange the purchase of those securities pursuant to the terms and conditions of the agreement. We will not receive any of the proceeds from the sale by any selling stockholder of the warrants or the underlying common stock. The 7,111 shares of common stock held by VMW, Inc., a selling stockholder, are not subject to the above referenced agreement. VMW may sell its common stock from time to time in one or more transactions on the American Stock Exchange, in foreign markets, special offerings, exchange distributions, secondary distributions, negotiated transactions, or a combination of these transactions. 6 The 265,854 shares of common stock held in our treasury are also not subject to the above referenced agreement. Use of Proceeds We will not receive proceeds from the sale of selling stockholders' securities. We will receive proceeds from the sale of the 265,854 shares of common stock we own and we will receive approximately$6,500,000 when the warrants are exercised, assuming all of the warrants are exercised. We intend to use these proceeds for general corporate purposes. Pending use of the proceeds, they will be invested in short term, interest bearing securities or money market funds. 7 Risk Factors You should carefully consider the following factors and other information in this prospectus before deciding to invest in shares of common stock. This prospectus contains forward-looking statements which can be identified by the use of words such as "intend," "anticipate," "believe," "estimate," "project," or "expect" or other similar statements. These statements discuss future expectations, contain projections of results of operations or of financial condition, or state other "forward-looking" information. When considering these statements, you should keep in mind the risk factors described below and other cautionary statements in this prospectus. The risk factors described below and other factors noted throughout this prospectus, including certain risks and uncertainties, could cause our actual results to differ materially from those contained in any forward-looking statement. 1. We may continue to incur substantial losses and our future profitability is uncertain. We began operations in 1966 and last reported net profit from 1985 through 1987. Since 1987, we have incurred substantial operating losses and as of March 31, 1999 our accumulated deficit was approximately $64,616,059. We have not yet generated significant revenues from our products and may incur substantial and increased losses in the future. We cannot assure you that we will ever achieve significant revenues from product sales or become profitable. We require and will continue to require the commitment of substantial resources to develop our products. In addition, substantial funding may be required to spin-off Core Biotech Corp. We cannot assure you that our product development efforts will be successfully completed or that required regulatory approvals will be obtained or that any products will be manufactured and marketed successfully, or profitability. 2. We do not expect to be profitable unless we receive final regulatory approval for Ampligen and it is successfully commercialized. Our principal development efforts are currently focused on Ampligen which has not been approved for commercial use in the U.S. or elsewhere. We do not expect to be profitable unless we receive final regulatory approval and can successfully commercialize Ampligen or one of our other products. Our products, including Ampligen, are subject to extensive regulation by numerous governmental authorities in the U.S. and other countries, including, but not limited to, the Food and Drug Administration in the U.S., the Health Protection Branch of Canada's Department of Health and Welfare, a federal regulatory agency in Canada, and the European Medical Evaluation Agency in Europe. Obtaining regulatory approvals is a rigorous and lengthy process and requires the expenditure of substantial resources. In order to obtain final regulatory approval of a new drug, we must demonstrate to the satisfaction of the regulatory agency that the product is safe and effective for its intended uses and that we are capable of manufacturing the product to the applicable regulatory standards. We require 8 regulatory approvals in order to market our products and receive product revenues or royalties. No regulatory agency has approved the full commercial sale of any of our products. We cannot assure you that the drug will ultimately be demonstrated to be safe or efficacious. In addition, while Ampligen is authorized for use in clinical trials in the United States and other countries, we cannot assure you that additional clinical trials approvals will be authorized in the United States or in other countries, in a timely fashion or at all, or that we will complete these clinical trials. Further, we cannot assure you that Ampligen will be commercially successful in any country that may approve its use. If Ampligen or one of our other products does not receive regulatory approval in the U.S. or elsewhere, our operations will be significantly affected. 3. We may not be profitable unless we can protect our patents and/or receive approval for additional pending patents. We need to acquire enforceable patents covering the use of Ampligen for a particular disease in order to obtain exclusive rights for the commercial sale of Ampligen. Our success depends, in large part, on our ability to obtain patent protection for our products and to obtain and preserve our trade secrets and knowhow. We have been issued certain patents on the use of Ampligen alone and Ampligen in combination with certain other drugs for the treatment of HIV. We have also been issued patents on the use of Ampligen alone and in combination with certain other drugs for the treatment of chronic hepatitis B virus, chronic hepatitis C virus, and a patent which affords protection on the use of Ampligen in patients with chronic fatigue syndrome. To date, we have not been issued any patents in the U.S. for the use of Ampligen as a sole treatment for any of the cancers which we have sought to target. Our applications for U.S. patents for the use of Ampligen in the treatment of renal cell carcinoma and lung cancer are currently pending. We cannot assure you that any of these applications will be approved or that our competitors will not seek and obtain patents regarding the use of Ampligen in combination with various other agents, including AZT, for a particular target indication prior to us. If we cannot protect our patents covering the use of Ampligen for a particular disease, or obtain additional pending patents, we may not be able to successfully market Ampligen. 4. We may not be profitable unless we can produce Ampligen in commercial quantities at costs acceptable to us. We have never produced Ampligen or any other products in large commercial quantities. Ampligen is currently produced only for use in clinical trials. We must manufacture our products in compliance with regulatory requirements at commercial quantities and at acceptable costs in order for us to be profitable. We intend to utilize third-party manufacturers and/or facilities if and when the need arises or, if we are unable to do so, to build or acquire commercial-scale manufacturing facilities. We have entered into an agreement with Bioclones, Ltd., a biopharmaceutical company which is associated with South African 9 Breweries, Ltd. The Bioclones agreement provides for the construction of a new commercial manufacturing facility by Ribotech, Ltd., a company of which we own 24.9%. We have not commenced constructing this facility. A pilot facility in South Africa is being expanded to provide an increased supply of Ampligen raw material. The construction of the commercial facility is dependent upon the regulatory status of Ampligen, or other products covered by our patents in various global markets, and we cannot give assurances with respect to when, and if, construction will be initiated or completed. If we cannot manufacture commercial quantities of Ampligen or enter into third party agreements for its manufacture at costs acceptable to us, our operations will be significantly affected. 5. If our distributors do not market our product successfully, we may not generate significant revenues or become profitable. We have limited marketing and sales capability. We need to enter into marketing agreements and third party distribution agreements for our products in order to generate significant revenues and become profitable. To the extent that we enter into co-marketing or other licensing arrangements, any revenues received by us will be dependent on the efforts of third parties, and there is no assurance that these efforts will be successful. Our agreement with Olsten Health Services offers the potential to provide significant marketing and distribution capacity in the United States while Bioclones, Ltd. will be responsible for fielding an adequate sales force in South America, Africa, United Kingdom, Australia and New Zealand. Olsten Health Services is able to deliver treatment and services to chronic disease patients including infusion services, home nursing and other medical services through a national network of more than 500 locations. Nevertheless, we cannot assure you that Olsten Health Services or Bioclones will be able to successfully distribute our products, or that we will be able to establish future marketing or third party distribution agreements on terms acceptable to us, or that the cost of establishing these arrangements will not exceed any product revenues. If we cannot enter into future marketing and distribution agreements at terms acceptable to us, or if these distributors cannot effectively market and distribute our products, our operations will be negatively affected. 6. We may be subject to product liability claims from the use of Ampligen or other of our products which could negatively affect our future operations. We face an inherent business risk of exposure to product liability claims in the event that the use of Ampligen or other of our products results in adverse effects. This liability might result from claims made directly by patients, hospitals, clinics or other consumers, or by pharmaceutical companies or others manufacturing these products on our behalf. Our future operations may be negatively effected from the litigation costs, settlement expenses and lost product sales inherent to these claims. While we will continue to attempt to take appropriate precautions, we cannot assure you that we will avoid significant product liability exposure. 10 Although we currently maintain worldwide product liability insurance coverage in the amount of $1,000,000, there can be no assurance that this insurance will provide adequate coverage against product liability claims. While no product liability claims are pending or threatened against us to date, a successful product liability claim against us in excess of our insurance coverage could have a negative effect on our business and financial condition. 7. Members of our Scientific Advisory Board have conflicting interests and may disclose data and technical knowhow to our competitors. All of our Scientific Advisory Board members are employed by other entities, which may include our competitors. Although we require each of our Scientific Advisory Board members to sign a non-disclosure and non-competition agreement with respect to the data and information that he or she receives from us, we cannot assure you that members will abide by them. If a member were to reveal this information to outside sources, accidentally or otherwise, our operations could be negatively effected. Since our business depends in large part on our ability to keep our knowhow confidential, any revelation of this information to a competitor or other source could have an adverse effect on our operations. 8. The loss of Dr. Carter's services could hurt our chances for success. Our success is dependent on the continued efforts of Dr. William A. Carter. The loss of Dr. Carter's services could have a material adverse effect on our operations. While we have an employment agreement with Dr. William A. Carter, and have secured key man life insurance in the amount of $2 million on the life of Dr. Carter, the loss of Dr. Carter or other key personnel, such as Dr. David Strayer or Dr. Carol Smith, or the failure to recruit additional personnel as needed could have a materially adverse effect on our ability to achieve our objectives. 9. Restricted shares eligible for sale may depress the market price of our common stock. A significant number of our outstanding shares of common stock are "restricted," as that term is defined under Rule 144 of the Securities Act. In addition, we have issued warrants to purchase 2,080,000 shares of common stock in reliance upon the provisions of Rule 701 of the Securities Act. All of these Rule 701 shares are currently eligible for sale, although the holder of 1,400,000 of these rule 701 shares, Dr. William Carter, our president, has agreed to not sell any of these shares in 1999. Under Rule 144, in general, a person may sell stock if the stock has been owned for at least one year. Rule 144 sales must be made under certain conditions, including, limitations as to the amount of shares that may be sold in any three-month period. Rule 144 also permits a sale, without any quantity limitation, by a person who is not an affiliate of the issuer and who has satisfied a two-year holding period. We cannot predict the effect that sales made under Rule 144 or Rule 701, sales made in reliance on other 11 exemptions under the securities laws or under registration statements may have on any then prevailing market price. The sale, or availability for sale, of these securities in the public market subsequent to this prospectus, could affect the market price of the common stock and could impair our ability to raise additional capital through the sale of our equity securities or debt financing. 10. We are dependent on our systems to operate our business, and failure to adequately address the Year 2000 problem could hurt our profitability. We are dependent upon computers to operate our business and therefore are exposed to Year 2000 problems. In the spring of 1998, we initiated a Y2K compliance program with the following objectives: (a) updating and/or replacing aging hardware; (b) establishing a new platform for data bases; and (c) assuring company-wide Y2K compliance. With the assistance of outside consultants, we learned that the computer systems used for clinical and manufacturing purposes are not Y2K compliant. In order to make these systems compliant, we elected to replace the computer systems. As of the date of this prospectus all of our computers and systems are Y2K compliant. The cost for this compliance was between $150,000 and $200,000. In a worst case scenario, we would experience delays in accessing data on patients enrolled in clinical trials. These delays could slow down regulatory compliance and commercial approval of Ampligen by the Food and Drug Administration. Our management of Ampligen production and inventories would be slow and time consuming, which could delay shipments of Ampligen for clinical trials. Our Y2K program is expected to significantly reduce our level of uncertainty about the Y2K problem and, in particular, about the Y2K compliance and readiness of our material external agents. We believe that, with the implementation of new business systems and completion of our Y2K program as scheduled, the possibility of significant interruptions or normal operations should be reduced. 12 Where you can find more information about Hemispherx We file annual, quarterly and special reports, proxy statements and other information with the SEC.

The applicable prospectus supplement will describe, where applicable, the terms of each warrant in respect of which this prospectus is being delivered. Selling Stockholders This prospectus relates to the proposed sale by us, agent or agents designated by us, or certain stockholders of: o 1,843,750 warrants owned by the selling stockholders o 1,843,750 shares of common stock underlying the selling stockholders' warrants o 7,111 share of common stock owned by a selling stockholder Although not set forth in this part of the prospectus, this prospectus also relates to the registration of 265,854 shares of common stock in our treasury. The following table sets forth as of June 14, 1999 certain information with respect to the selling stockholders. The selling stockholders have no material relationship with us and have not held any position or office with us during the past three years, except where noted. We will not receive any of the proceeds from the sale of the warrants or the shares of common stock underlying warrants.

Each selling stockholder has informed us of the price at which they will sell the warrants owned by them to us or an agent designated by us. We or an agent designated by us will purchase the warrants, exercise the warrants and sell the common stock underlying the warrants from time to time in one or more transactions on the American Stock Exchange, in foreign markets, special offerings, exchange distributions, secondary distributions, negotiated transactions, or a combination of these transactions. We or an agent designated by us may sell the securities at market prices at the time of sale, at prices related to the market price or at negotiated prices. If an agent designated by us is used in the sale, that agent will receive a commission of 10%, payable by the applicable selling stockholder. The commission represents 10% of the purchase price set by that selling stockholder. We will not receive commissions on sales made by us. After one year from the date of this prospectus, the selling stockholders may sell their securities from time to time directly to purchasers in one or more transactions on the American Stock Exchange, in foreign markets, special offerings, exchange distributions, secondary distributions, negotiated transactions, or a combination of these transactions. The common stock held by VMW, Inc., a selling stockholder in the table above, is not subject to the terms of the above described agreement. VMW may sell its common stock from time to time in one or more transactions on the American Stock Exchange, in foreign markets, special offerings, exchange distributions, secondary distributions, negotiated transactions, or a combination of these transactions. A prospectus supplement with respect to the securities being offered subject to the above described agreement will set forth the terms of the offering of the offered securities, including the name or names of any underwriters or agents, the purchase price of the offered securities, any underwriting discounts and other items constituting underwriters' compensation, any initial public offering price and any discounts or concessions allowed or reallowed or paid to dealers. Any initial public offering price and any discounts or concessions allowed or reallowed or paid to dealers may be changed from time to time. 16 If underwriters are used in the sale, the offered securities subject to the agreement described above will be acquired by the underwriters for their own account and may be resold from time to time in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale. The offered securities may be offered to the public either through underwriting syndicates represented by one or more managing underwriters or directly by one or more underwriters. The underwriter or underwriters with respect to a particular underwritten offering of securities, or, if an underwriting syndicate is used, the managing underwriter or underwriters, will be set forth on the cover of the applicable prospectus supplement. Unless otherwise set forth in the prospectus supplement relating thereto, the obligations of the underwriters to purchase the offered securities will be subject to conditions precedent and the underwriters will be obligated to purchase all of the offered securities if any are purchased. If dealers are utilized in the sale of the offered securities subject to the agreement described above in respect of which this prospectus is delivered, and if so specified in the applicable prospectus supplement, we will sell such offered securities to the dealers as principals. The dealers may then resell the offered securities to the public at varying prices to be determined by such dealers at the time of resale. The names of the dealers will be set forth in a prospectus supplement. The offered securities subject to the agreement described above may be sold directly by us or through agents designated by us from time to time. Any agent involved in the offer or sale of the offered securities in respect to which this prospectus is delivered will be named, and any commissions payable to the agent, will be set forth in a prospectus supplement. Sales of the common stock may also be made under Rule 144 of the Securities Act of 1933, where applicable. The selling stockholders' shares may also be offered in one or more underwritten offerings, on a firm commitment or best efforts basis. We will not receive proceeds from the sale of the selling stockholders' securities. From time to time each of the selling stockholders may transfer, pledge, donate or assign their securities to lenders, family members and others and each of such persons will be deemed to be selling stockholders for the purposes of this prospectus. The number of selling stockholders securities beneficially owned by those selling stockholders who so transfer, pledge, donate or assign selling stockholder securities will decrease as and when they take this action. The plan of distribution for the selling stockholders securities sold hereunder will otherwise remain unchanged, except that the transferees, pledgees, donees or other successors will be selling stockholders hereunder. Under applicable rule and regulations under the Exchange Act, any person engaged in the distribution of the common stock may not bid for or purchase shares of common stock 17 during a period which commences one business day, or 5 business days if our public float is less than $25 million or our average daily trading volume is less than $100,000, prior to the person's participation in the distribution, subject to exceptions for certain passive market making activities. In addition and without limiting the foregoing, the selling stockholders will be subject to applicable provisions of the Exchange Act and the rules and regulations thereunder, including, without limitation, Regulation M which may limit the timing of purchases and sales of common stock by selling stockholders. We are bearing all costs relating to the registration of the shares of common stock, other than fees and expenses, if any, of counsel or other advisors to the selling stockholders. Any commissions, discounts or other fees payable to our designated agent in connection with any sale of the securities will be borne by the selling stockholders.

Disclosure of Commission Position on Indemnification for Securities Act Liabilities Insofar as indemnification for liabilities arising under the Securities Act may be permitted to our directors, officers, and controlling persons, we have been advised that in the 18 opinion of the Commission this indemnification is against public policy as expressed in the Securities Act and is, therefore unenforceable. In the event that a claim for indemnification against these liabilities, other than our payment of expense incurred or paid by one of our directors, officers, or controlling persons in the successful defense of any action, suit or proceeding, is asserted by that director, officer or controlling person in connection with the securities being registered, we will, unless in the opinion of our counsel the matter has been settled by a controlling precedent, submit to a court of appropriate jurisdiction the question whether this indemnification by us is against public policy as expressed in the Securities Act and will be governed by the final adjudication of these issues. 19 ================================================================================ No dealer, salesman or any other person is authorized to give any information or to represent anything not contained in this prospectus.

Item 15. Indemnification of Directors and Officers. The Restated Certificate of Incorporation of the Company provides as follows: No person who is or was a director of this Corporation shall be personally liable to the Corporation or its stockholders for monetary damages for the breach of any fiduciary duty as a director, unless, and only to the extent that, such director is liable (i) for any breach of the director's duty of loyalty to the Corporation or its stockholder, (ii) for acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law, (iii) under Section 174 of the General Corporation Law of the State of Delaware, or (iv) for any transaction form which the director derived an improper personal benefit. Section 145 of the Delaware General Corporation Law gives Delaware corporations the power to indemnify each of the Company's present and former officers and directors under certain circumstances, if such person acted in good faith and in a manner which he reasonably believed to be in, or not opposed to, the best interests of the corporation. The Company's Restated Certificate of Incorporation generally requires the Company to indemnify directors and officers to the fullest extent permissible under Delaware law. The Company has entered into indemnification agreements with its current directors and certain of its executive officers. These agreements have the practical effect in certain cases of eliminating the ability of stockholders to collect monetary damages from such individuals. II-1 Item 16.

II-2 All schedules are omitted from this Registration Statement because they are not required or the required information is included in the Consolidated Financial Statement or the Notes thereto. Item 17. Undertakings. (a) Rule 415 Offerings. The undersigned issuer hereby undertakes that it will: (1) File, during any period in which it offers or sells securities, a post-effective amendment to this Registration Statement to: (i) Include any prospectus required by Section 10(a)(3) of the Securities Act; (ii) Reflect in the prospectus any facts or events which, individually or together, represent a fundamental change in the information in the Registration Statement; and (iii) Includes any additional or changed material information on the plan of distribution. provided, however, the paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the Registration Statement is on Form S-3 or Form S-8, and the information required in a post-effective amendment by those paragraphs is contained in periodic reports filed 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. (2) For determining liability under the Securities Act, treat each post-effective amendment as a new registration statement of the securities offered, and the offering of the securities at that time to be the initial bona fide offering. (3) File a post-effective amendment to remove from registration any of the securities that remain unsold at the end of the offering. (b) Request for acceleration of effective date. (1) Insofar as indemnification for liabilities arising under the Securities Act, may be permitted to directors, officers and controlling persons of the small business issuer pursuant to the foregoing provisions, or otherwise, the issuer has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the issuer of expenses incurred or paid by a director, officer or controlling person of the issuer in the successful defense of any action, suit or II-3 proceedings) is asserted by such director, officer or controlling person in connection with the securities being registered, the issuer 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 Securities Act and will be governed by the final adjudication of such court. (2) For determining any liability under the Securities Act, treat each post-effective amendment that contains a form of prospectus as a new registration statement for the securities offered in the registration statement, and that offering of the securities at that time as the initial bona fide offering of those securities.
