SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS Certain statements in this Prospectus under the captions "Risk Factors" and "The Company" constitute "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995 (the "Reform Act"). Such forward-looking statements involve known and unknown risks, uncertainties and other factors that may cause the actual results, performance or activities of the Company, or industry results, to be materially different from any future results, performance or activities expressed or implied by such forward-looking statements. Such factors include: general economic and business conditions, the financial condition of the Company, competition, the Company's dependence on other companies to commercialize, manufacture and sell products using the Company's technologies, the uncertainty of results of preclinical and clinical testing, the risk of product liability and liability for human clinical trials, the Company's dependence on patents and other proprietary rights, dependence on key management officials, the availability and cost of capital, the availability of qualified personnel, changes in, or the failure to comply with, governmental regulations, the failure to obtain regulatory approvals of the Company's products and other factors discussed in this Prospectus. See "Risk Factors". RISK FACTORS Prospective investors should consider carefully the following factors concerning the Company and its business before purchasing securities offered by this Prospectus. Certain statements under this caption constitute "forward-looking statements" under the Reform Act. See "Special Note Regarding Forward-Looking Statements." Absence of Operating Revenues and Liquidity; History of Losses; Auditors' Report - Going Concern Considerations. The Company has incurred annual operating losses since its inception and, as a result, at March 31, 1996, had an accumulated deficit of $35,700,000. The Company has not received any significant operating revenues during the last five years. -4- In addition to operating its production facility and seeking approval for its Calcitonin for human use, the Company intends to continue certain internally funded research activities such as the development of a Calcitonin pill, all of which will contribute to continuing losses from operations. All of the Company's contracts to perform sponsored research have been completed or cancelled and, at present, it has almost no operating revenues. It is unlikely that the Company's operating results will improve unless it is able to license its technology, obtain new projects, or successfully produce and sell its products. The Company may continue to incur losses over the next several years. The auditors' report for the fiscal year ended December 31, 1995 contains an explanatory paragraph indicating there is substantial doubt about the Company's ability to continue as a going concern. The Company has sufficient financial resources to sustain its operations at the current level through approximately the third quarter of 1996. To continue its operations beyond that time will require that the Company enter into additional financing transactions or marketing, joint venture or licensing agreements. There can be no assurance that any such financings will occur or that any such agreements will be entered into by the Company. Transition to Production; Possibility of Delays or Inability to Manufacture and Market Products. The Company is currently undergoing a transition from its historical research orientation toward a business with a pharmaceutical production focus. Accordingly, the Company is likely to incur the problems, delays, expenses and difficulties typically encountered by enterprises in the Company's stage of transition, many of which may be beyond the Company's control. No product of the Company has been commercialized for human pharmaceutical use. The commercial manufacture and sale of any such product will require the approval of the U.S. Food and Drug Administration ("FDA") and by comparable regulatory authorities outside of the United States. See "Risk Factors - Government Regulation." There can be no assurance that clinical testing will be successful or that the clinical results will be adequate to support regulatory submissions. Furthermore, there can be no assurance that the Company's products will be demonstrated to be safe and effective or that they will be approved by the appropriate regulatory authorities. Even if any such products are approved, there is no assurance that they can be manufactured in commercial quantities at reasonable costs. Due to the Company's limited clinical, manufacturing and regulatory experience and the absence of a marketing organization, it may be necessary for the Company to rely on sponsors or other parties to perform such tasks for the commercialization of pharmaceutical-grade products. See "Risk Factors - Dependence on Large Pharmaceutical Companies." Expanded consumer acceptance of pharmaceutical-grade Calcitonin may be dependent on development of a consumer acceptable delivery system. The Company and others are conducting research on new delivery systems for Calcitonin including oral technology. There can be no assurance that the Company will develop suitable oral delivery systems or that governmental approval of any such delivery system will be obtained. There can also be no assurance that others will not develop oral or other delivery systems that could compete with or surpass any oral delivery system developed by the Company. Moreover, there are non-Calcitonin products currently being marketed for osteoporosis treatment and other non- Calcitonin products in development that will compete with Calcitonin products. See "Risk Factors - Technological Change and Competition." -5- There can be no assurance that the Company will have sufficient financial resources to fund its operations until such time as it is able to generate revenues that are sufficient to sustain its operations. See "Risk Factors - Absence of Operating Revenues and Liquidity; History of Losses; Auditors' Report - Going Concern Considerations." New Production Facility. During 1994, the Company completed construction of a facility for the production of pharmaceutical-grade Calcitonin and other peptide hormones. The Company is leasing the facility under a 10-year agreement which began in February 1994. The Company has two 10-year renewal options as well as an option to purchase the facility. The Company is undertaking steps to secure FDA validation of the facility which would allow it to manufacture Calcitonin for human pharmaceutical use. The facility has begun producing Calcitonin in accordance with current Good Manufacturing Practice ("cGMP") regulations, but there is no assurance that the facility will be approved by the FDA. Furthermore, there can be no assurance that the facility will be able to achieve its production goals, that production at this facility will be profitable to the Company, that others will not develop processes and products superior to, or otherwise precluding the Company from commercial utilization of this facility, that there will be a market for the Company's products produced by the facility, or that sufficient funds will be available for the Company to complete the pre-production process or to produce and market its products from the facility. Dependence on Large Pharmaceutical Companies. The Company has been and expects to continue to be dependent on large pharmaceutical companies for revenues from sales of product, research sponsorship, joint ventures and licensing arrangements. During the 1987 to 1990 period, the Company's operating revenues resulted primarily from research which was totally or substantially funded by pharmaceutical companies. The Company currently has no sponsored research projects. There is no assurance that the Company will be successful in its efforts to enter into new research or licensing agreements or other revenue producing arrangements. The Company's past contracts with certain pharmaceutical company sponsors provide for payment of royalties to the Company on commercial sales of the products of sponsored research projects. However, there can be no assurance that such sponsors will successfully commercialize any product based on the Company's technology. It currently is unlikely that the Company will receive any material royalties under such past agreements. In June 1995, the Company entered into a joint venture agreement with the Qingdao General Pharmaceutical Company and its Huanghai factory for the production and marketing of Calcitonin in China. Under the agreement, the Chinese partners will finance the project, including the construction and operation of a dedicated manufacturing facility in China which will utilize the Company's propriety production technology. The Company will provide the joint venture with technology and training as well as the Company's proprietary enzyme at a discounted price. The Company will receive a combination of fixed fees and minimum annual royalties based upon sales of the end product. There is no assurance that this joint venture will be successful or that the Company will receive significant income from the joint venture. -6- Risks of International Operations. The Company's potential major customers, partners and licensees include foreign companies or companies with significant international business. The business operations of such companies and their ability to pay license fees, royalties and other amounts due and otherwise to perform their obligations to the Company under agreements with the Company may be subject to approval or regulation by foreign governments. There can be no assurance that required approvals will be received. The failure to receive required approvals, governmental regulations and other risks, including political and foreign currency risks, could affect the ability of the Company to earn or receive payments pursuant to such agreements and, in such event, may have a material adverse effect on the Company's future operations. Technological Change and Competition. The Company has concentrated most of its efforts on one product - the use of Calcitonin for the treatment of osteoporosis. The market for this treatment of osteoporosis is subject to rapid, unpredictable and significant technological change. Competition from specialized biotechnology companies, major pharmaceutical and chemical companies and universities and research institutions is intense. Most of the competitors of the Company have substantially greater financial and other resources than does the Company. There can be no assurance that developments by others, including alternative chemical means of amidation, alternative processes which eliminate the need for amidation, and new delivery systems and other osteoporsis treatments, will not render the Company's technologies and products derived therefrom obsolete or noncompetitive. Product Liability. Product liability claims relating to the Company's technology or products may be asserted against the Company. There can be no assurance that the Company will have sufficient resources to defend against or satisfy any such liability. Although the Company has recently obtained product liability insurance coverage, product liability or other judgments against the Company in excess of insurance limits could have a material adverse effect upon the Company's business and financial condition. Patents and Proprietary Technology. The Company has filed applications for U.S. patents relating to the proprietary amidation and immunization processes and Calcitonin pill invented in the course of its research. To date, the following two patents have issued: Immunization By Immunogenic Implant, a process patent, and Alpha-Amidation Enzyme, a process and product patent. Other applications are pending. Filings related to the amidation process have also been made in selected foreign countries and nine such foreign patents have issued. There can be no assurance that any of the Company's pending applications will issue as patents or that the Company's issued patents will provide the Company with significant competitive advantages. Furthermore, there can be no assurance that competitors will not independently develop or obtain similar or superior technologies. Although the Company believes its patents and patent applications are valid, the invalidation of its Alpha-Amidation Enzyme patent or the failure of certain of its pending Alpha-Amidation Enzyme-related applications to issue as patents could have a material adverse effect upon the Company's business. Difficulties in detecting and proving infringement are generally greater with process patents than with product patents. In addition, the value of a process patent may be reduced if the products that can be produced using such process have been patented by others. Under such -7- circumstances, the cooperation of these patent holders or their sublicensees would be needed for the commercialization of the aforementioned patented products in countries where these companies hold valid patents. In some cases, the Company relies on trade secrets to protect its inventions. It is the policy of the Company to include in all research contracts, joint development agreements and consulting relationships that provide access to the Company's trade secrets and other know-how confidentiality obligations binding on the parties involved. However, there can be no assurance that these secrecy obligations will not be breached to the detriment of the Company. To the extent sponsors, consultants or other third parties apply technological information independently developed by them or by others to Company projects, disputes may arise as to the proprietary rights to such information which may not be resolved in favor of the Company. Government Regulation. The laboratory research activities of the Company and its sponsors, collaborators and licensees, and the processes and products which may be developed by them and the new production facility, are subject to significant regulation by numerous federal, state, local and foreign governmental authorities. In addition to obtaining the FDA's validation of the new facility, it is necessary to obtain FDA approval for human use of the Calcitonin to be produced in the facility. This will require various human and animal studies. The Company will then apply to the FDA for approval of the Company's Calcitonin for human use. The regulatory process for a pharmaceutical product may take a number of years and requires substantial resources. In the case of the regulatory process for the Company's Calcitonin products, the Company believes that it may be possible to abbreviate the process. However, there can be no assurance that regulatory approval will be obtained for the new facility or any of the Company's products. The inability to obtain, or delays in obtaining, such approvals would adversely affect the Company's ability to continue to fund its programs, produce marketable products, or to receive revenue from product sales or royalties. Furthermore, the extent of any adverse governmental regulation that may arise from future legislative and administrative action cannot be predicted. Dependence on Key Executives. Drs. Warren and Ronald Levy have been the principal executive officers of the Company since its inception. The Company relies on them for their leadership and scientific direction. Neither Dr. Warren P. Levy nor Dr. Ronald S. Levy has an employment agreement with the Company. Each of them has entered into an agreement with the Company providing that he shall not engage in any other employment or business for the period of his employment with the Company. At the present time, the loss of the services of either of these individuals could have a material adverse impact on the Company's business. Attraction and Retention of Key Personnel. The Company's ability to obtain required governmental approvals, produce its products, obtain research contracts and develop new technologies will depend in part on its ability to attract and retain highly qualified scientific personnel. Competition for such personnel is intense. There can be no assurance that the Company will be able to attract and retain such personnel. Shares Eligible For Future Sale; Outstanding Convertible Securities, Warrants And Options. Other than the issued or to be issued shares of Common - 8 - Stock to which this Prospectus relates, there are 7,982,177 shares of Common Stock that are registered under the Securities Act and are issuable upon exercise of its publicly traded Class B Warrants at an exercise price of 3.504 per share as of June 28, 1996; as of June 25, 1996, approximately 2,700,000 shares of Common Stock that are issuable upon conversion of the balance of the Company's 10% convertible debentures; and 1,603,265 shares issuable under purchase options exercisable at prices ranging from $1.00 to $3.00 per share. In addition, 4,138,350 outstanding shares of Common Stock are "restricted securities" as that term is defined by Rule 144 promulgated under the Securities Act. Such restricted securities may be sold only in compliance with Rule 144, or pursuant to registration under the Securities Act or pursuant to another exemption therefrom. The Company may issue additional convertible securities, options, warrants and shares in the future. Transactions by the Company, or the occurrence of certain other future events, may require adjustment of the exercise or conversion price and other terms of the Company's convertible securities, options and warrants including, in some circumstances, an increase in the number of shares issuable thereunder. The Company cannot predict the adverse effect that market sales of Common Stock, the conversion of such convertible securities, the exercise of such options or warrants, or the availability of Common Stock for sale will have on the market price of the Common Stock prevailing from time to time, although it is likely that sales of a large number of securities would depress such market price. The Company also cannot predict the adverse effect, if any, that such convertible securities, options, warrants and shares available for sale will have on the ability of the Company to obtain additional capital or the terms and conditions thereof. Possible Volatility of Securities Prices. The market prices of the Company's securities may be highly volatile. Factors such as announcements by the Company or others of technological innovations, regulatory matters, new products or procedures, proposed government regulations, developments or disputes relating to patents or proprietary rights, and public concern over the safety of activities or products may have a significant impact on the market price of the Company's securities. In addition, future sales of shares of Common Stock by shareholders and by the holders of convertible securities, warrants and options could have an adverse effect on the prices of the Company's securities. See "Risk Factors - Shares Eligible for Future Sale; Outstanding Convertible Securities, Warrants and Options." Voting Control. Warren P. Levy, Ronald S. Levy and Jay Levy, founders of the Company, beneficially own, approximately 16% of the outstanding Common Stock (assuming that outstanding convertible securities, warrants and options held by others are not converted or exercised) and, thus, effectively may have the ability to elect the entire Board of Directors and control the affairs of the Company. Dividends. The Company has not paid any cash dividends on its Common Stock since its inception and anticipates that, for the foreseeable future, it will not pay any cash dividends. Limitation of Marketability of Company Securities. The Common Stock currently is traded on the Nasdaq National Market. In order for the Common Stock to continue to qualify for inclusion on the Nasdaq National Market, among other requirements, the Company must have net tangible assets of at least $4.0 million. As of March 31, 1996 the amount of the Company's net tangible assets -9- was approximately $3.0 million. See "Risk Factors - Absence of Operating Revenues and Liquidity; History of Losses; Auditors' Report - Going Concern Considerations." The Company has been advised by the National Association of Securities Dealers, Inc. (the "NASD") that due to a deficiency in its net tangible assets at March 31, the Company currently does not qualify for the listing of its Common Stock on the Nasdaq National Market. The Company is appealing this determination. If the Company is unable to develop a plan satisfactory to the NASD by which it will be able to restore and maintain compliance with the Nasdaq National Market listing requirements, the Common Stock will be removed from trading on the Nasdaq National Market. There is no assurance, however, that the Company will be successful in preventing the removal of the Common Stock from trading on the Nasdaq National Market. If the Common Stock is removed from trading on the Nasdaq National Market, the Company intends to make an application for the listing of the Common Stock on the Nasdaq SmallCap Market. If the Company fails to meet the requirements for trading on the Nasdaq National Market and does not qualify for listing in the Nasdaq SmallCap Market, the holders of Common Stock may find it difficult to obtain accurate quotations as to the market value of the Common Stock and may experience greater difficulties in attempting to sell the Common Stock than if it were listed on a stock exchange or quoted on the Nasdaq National Market or the Nasdaq SmallCap Market. If the Common Stock is not traded on the Nasdaq National Market or the Nasdaq SmallCap Market, and the market price of the Common Stock is less than $5.00 per share, the Common Stock would be classified as a "penny stock." As such the Common Stock would be subject to Rule 15g-9 under the Exchange Act, which imposes additional sales practice requirements on broker-dealers that recommend the purchase or sale of such securities to persons other than a person who qualifies as an "established customer" or an "accredited investor." Among these requirements is that a broker-dealer must make a determination that investments in penny stocks are suitable for the customer and must make certain special disclosures to the customer concerning the risks of penny stocks. Application of the penny stock rules to the Common Stock could adversely affect the market liquidity of such securities, which in turn may affect the ability of the holders of the Common Stock to resell the securities. - 10 - THE COMPANY Unigene Laboratories, Inc. is a health-care oriented biotechnology company which is engaged in research and production of cGMP Calcitonin and is planning to engage in the production and marketing in bulk of pharmaceutical grade Calcitonin. Certain statements under this caption constitute "forward- looking statements" under the Reform Act. See "Special Note Regarding Forward- Looking Statements." The Company's current business focus has shifted toward pharmaceutical production from its historical research orientation. The Company has succeeded in combining its proprietary amidation process with bacterial recombinant DNA technology to develop a peptide hormone production process. The Company believes that its proprietary amidation process will be a key step in the more efficient and economical commercial production of certain peptide hormones with diverse therapeutic applications. Many of these hormones cannot be produced at a reasonable cost in sufficient quantities for clinical testing or commercial use by currently available production processes. Using its proprietary process, the Company has produced laboratory-scale quantities of seven such peptide hormones: human Calcitonin, salmon Calcitonin, human Growth Hormone Releasing Factor, human Calcitonin Gene-Related Peptide, human Corticotropin Releasing Factor, human Amylin and a human Magainin. During 1991, a study commissioned by the Company was prepared by a professor of chemical engineering at the Massachusetts Institute of Technology. The study evaluated the economics for producing multi-kilogram quantities of Calcitonin and indicated that the Company's process for producing Calcitonin should reduce the cost and time required for commercial production by up to 95%. The Company's strategy is to develop proprietary products and processes with applications in human health-care, independently or in conjunction with pharmaceutical and chemical companies, in order to generate revenues from license fees, royalties and product sales in bulk. Generally, the Company seeks sponsors and licensees to provide research funding and assume responsibility for obtaining appropriate regulatory approvals, clinical testing, production and marketing of products derived from the Company's research activities. It has concentrated most of its efforts on one product - Calcitonin for the treatment of osteoporosis. The Company has built a production facility and plans to undertake production of pharmaceutical grade Calcitonin and will assume responsibility for the clinical testing and/or applying for regulatory approval for certain Calcitonin products. Since 1992, the Company has been producing and from time to time selling small quantities of research-grade salmon Calcitonin. During 1993, the Company began construction of a cGMP facility for the production of pharmaceutical-grade Calcitonin in leased premises located in Boonton, New Jersey which was mechanically completed during the fourth quarter of 1994. The facility will also produce the Company's proprietary amidating enzyme for use in producing Calcitonin. The initial production capacity of the facility is expected to be between 0.5-1.0 kilograms of bulk Calcitonin per year, representing approximately 10% of the current estimated world supply for this leading osteoporosis drug. The Company is following conventional procedures in order to secure the validation of the facility by the FDA in order to allow the Company to provide its Calcitonin for human use. Although the facility was inspected by an independent consultant and found to be in compliance with cGMP guidelines, there can be no assurance that FDA validation will occur. In addition there is no assurance that the facility production goals will be achieved, that there will be a market for the Company's products, that such production will be profitable - 11 - to the Company, that others will not develop processes and products superior to, or otherwise precluding the commercial utilization of, the processes or products developed by the Company. The design of the facility is intended to allow for substantial increases in Calcitonin production utilizing the existing equipment with no additional capital expenditures or personnel. Although the facility will initially be exclusively devoted to Calcitonin production, it would be suitable for producing other peptide hormone products in the future. There can be no assurance that there will be sufficient acceptance of the Company's products in the marketplace for successful commercialization. See "Risk Factors - New Production Facility." In addition to obtaining the FDA's validation of the new facility, it is necessary to obtain regulatory approval in each country for human use of the salmon Calcitonin to be produced in the facility. This will require various human and animal studies. The Company will then apply to the appropriate regulatory agencies for approval of the Company's Calcitonin for human use. The Company requested in May 1996 that the regulatory authority for drugs in the United Kingdom authorize the Company to conduct pivotal clinical Phase III trials of its injectable form of Calcitonin, which request was granted in June 1996. The Company expects the trial to be completed during the fourth quarter of 1996. The Company plans to apply for marketing authorization throughout the European Union soon after completion of the clinical trial. In addition, the Company recently filed an Investigational New Drug (IND) application for its injectable form of Calcitonin with the FDA. However, there can be no assurance that these studies will produce satisfactory results or that the necessary governmental approvals will be obtained as projected. Expanded consumer acceptance of pharmaceutical-grade Calcitonin may be dependent on development of a consumer acceptable delivery system. A major pharmaceutical company received FDA approval during 1995 for the marketing of a nasal spray delivery system for Calcitonin, which could enlarge the market for Calcitonin. The Company and others are conducting research on oral delivery systems for Calcitonin. There can be no assurance that suitable delivery systems will be developed or that governmental approval of such delivery systems will be obtained. The Company is continuing its efforts to develop a Calcitonin pill. In December, 1995 and the first half of 1996, the Company successfully tested its proprietary Calcitonin pill in Phase I clinical trials in the United Kingdom. The latest of these studies indicated that all of the subjects who received the pill showed levels of the hormone in blood samples taken during the trial which are greater than levels generally regarded as required for maximal therapeutic benefit. The Company believes that this is the first time significant blood levels of Calcitonin have been observed in humans following oral administration of the hormone. However, there is no assurance that these results will be replicated in further studies. The Company has recently filed a patent application for its oral formulation with the U.S. Patent and Trademark Office and plans to file an Investigational New Drug (IND) application with the FDA. There can be no assurance that either application will be approved as projected or that the Company will be successful in marketing its products. The planned activities of the Company are all subject to obtaining adequate financing. There can be no assurance that the Company will have sufficient resources to complete the preproduction process, to produce and market its products and to carry on its other projects. See "Risk Factors - Absence of Operating Revenues and Liquidity; History of Losses; Auditors' Report - - Going Concern Considerations." - 12 - The Company is currently engaged in two collaborative research programs. One, with Rutgers University College of Pharmacy, seeks to develop an oral drug delivery system for Calcitonin. The second collaboration, performed in conjunction with Yale University, is investigating novel applications for certain amidated peptide hormones, including CGRP, Calcitonin gene-related peptide. At present, the Company has no third party sponsored research agreements in effect. The Company is currently conducting discussions with major pharmaceutical companies regarding licensing and/or research agreements. There can be no assurance that such discussions will result in new research or licensing agreements or that the Company will be able to obtain adequate funding for its current or new projects. The Company is dependent on large pharmaceutical companies, having much greater resources than the Company, for revenues from sales of product, research sponsorship, joint ventures and licensing arrangements. See "Risk Factors - Dependence on Large Pharmaceutical Companies" and "Risk Factors - Risks of International Operations." The Company has established a multi-disciplinary research team to adapt current genetic engineering technologies to the development of proprietary products and processes. The Company, at June 1, 1996, had 60 full-time employees, including 25 research and development personnel and 24 pre-production personnel. 10 employees have Ph.D. degrees in the fields of molecular biology, microbiology, biochemistry, pharmacology or organic chemistry. The Company's employees have expertise in molecular biology, including DNA cloning, synthesis, sequencing and expression; protein chemistry, including purification, amino acid analysis, synthesis and sequencing proteins; immunology, including tissue culture, monoclonal and polyclonal antibody production and immunoassay development; chemical engineering; pharmaceutical production; quality assurance; and quality control. None of the Company's employees is covered by a collective bargaining agreement. The Company was incorporated under the laws of the State of Delaware in November 1980.

Whether sales of shares will be made, and the timing and amount of any sale made, is within the sole discretion of the Selling Shareholders. The Common Stock covered by this Prospectus may be offered for sale from time to time by the Selling Shareholders to or through underwriters or directly to other purchasers or through agents in one or more market transactions, in one or more private transactions or in a combination of such methods of sale, at prices then prevailing, at prices related to such prices or at negotiated prices. Such methods of distribution may include, without limitation: (a) a block trade in which the broker-dealer so engaged will attempt to sell the Common Stock as agent but may position and resell a portion of the block as a principal to facilitate the transaction; (b) purchases by a broker-dealer as a principal and resale by such broker-dealer for its own account pursuant to this Prospectus; (c) ordinary brokerage transactions and transactions in which the broker solicits purchasers; and (d) face-to-face transactions between sellers and purchasers without a broker or dealer. This Prospectus may be amended and supplemented from time to time to describe a specific plan of distribution. In connection with distributions of the Common Stock or otherwise, the Selling Shareholders may enter into hedging transactions with broker-dealers or other financial institutions. In connection with such transactions, broker-dealers or other financial institutions may engage in short sales of Common Stock in the course of hedging the positions they assume with Selling Shareholders. The Selling Shareholders may also sell Common Stock short and redeliver the shares to close out such short positions. The Selling Shareholders may also enter into options or other transactions with broker-dealers or other financial institutions which require the delivery to such broker-dealer or financial institution of the Common Stock offered hereby, which Common Stock such broker-dealer or other financial institutions may resell pursuant to this Prospectus (as supplemented or amended to reflect such transaction). The Selling Shareholders may also pledge the shares registered hereunder to a broker-dealer or other financial institution and, upon a default, such broker-dealer or other financial institution may effect sales of the pledged Common Stock pursuant to this Prospectus (as supplemented or amended to reflect such transaction). In addition, any Common Stock covered by this Prospectus that qualifies for sale pursuant to Rule 144 under the Securities Act may be sold under Rule 144 rather than pursuant to this Prospectus. Brokers, dealers or agents may receive compensation in the form of commissions, discounts or concessions from Selling Shareholders in amounts to be negotiated in connection with sales pursuant hereto. Such brokers or dealers and any other participating brokers or dealers may be deemed to be "underwriters" within the meaning of the Securities Act in connection with such sales and any such commission, discount or concession may be deemed to be underwriting discounts or commissions under the Securities Act. - 18 - Certain costs, expenses and fees in connection with the registration of the Common Stock will be borne by the Company. Commissions, discounts and transfer taxes, if any, attributable to the sales of the Common Stock will be borne by the Selling Shareholders. Certain of the Selling Shareholders have agreed or may agree to indemnify the Company or any underwriter, as the case may be, and any of their respective affiliates, directors, officers and controlling persons, against certain liabilities in connection with the offering of the Common Stock pursuant to this Prospectus, including liabilities arising under the Securities Act. In addition, the Company has in some cases agreed to indemnify the Selling Shareholders or any underwriter, as the case may be, and any of their respective affiliates, directors, officers and controlling persons, against certain liabilities in connection with the offering of the Common Stock pursuant to this Prospectus, including liabilities arising under the Securities Act. The Company has agreed to supply the Selling Shareholders with such number of copies of this Prospectus as they may reasonably request.
