FILED PURSUANT TO RULE 424(b)(3) PROSPECTUS 1,385,751 SHARES CHESAPEAKE BIOLOGICAL LABORATORIES, INC. COMMON STOCK ----------- This prospectus relates to the public offering of shares of common stock of Chesapeake Biological Laboratories, Inc. by selling stockholders. We list these selling stockholders later in this prospectus. We will not receive any proceeds from the sale of shares offered by this prospectus. However, we will receive cash upon any exercise of the warrants described in this prospectus. Our common stock is quoted on the Nasdaq National Market under the symbol "CBLI." On December 1, 1999, the last sale price for the common stock as reported on the Nasdaq Stock Market was $2.6875 per share. BEGINNING ON PAGE 2, WE HAVE LISTED SEVERAL "RISK FACTORS" WHICH YOU SHOULD CONSIDER. YOU SHOULD READ THE ENTIRE PROSPECTUS CAREFULLY BEFORE YOU MAKE YOUR INVESTMENT DECISION. NEITHER THE SEC NOR ANY STATE SECURITIES COMMISSION HAS APPROVED OR DISAPPROVED OF THESE SECURITIES OR DETERMINED IF THIS PROSPECTUS IS TRUTHFUL OR COMPLETE. ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE. The date of this prospectus is December 2, 1999. CHESAPEAKE BIOLOGICAL LABORATORIES, INC. Our customers generally use the products we produce for clinical testing required for FDA approval. After approval customers market and sell these products for FDA-approved medical uses, most often as drugs to prevent or treat diseases. The nature of the ingredients in our products makes them effective only in injectable or sterile form. Generally, the FDA has not approved our customers' products for the same uses in other forms. Our customers range from major international pharmaceutical firms to emerging biotechnology companies. Since 1990, we have provided services on a contract basis to more than 100 pharmaceutical and biotechnology companies. After we perform our work, our customers take the products and either continue the process of obtaining FDA approval or market and sell FDA-approved products to the medical industry. Our mix of product development work versus product manufacturing depends entirely on the contracts we have at any given time. Customers contract with us for the following different services at different times: - production of development stage products for use in FDA required toxicology studies and clinical trials; and - production and manufacture of FDA approved products for commercial sale. In our manufacturing process, we derive biopharmaceutical products from biological materials. The biopharmaceutical products typically involve larger, more complex molecules than traditional pharmaceutical products, which come from smaller, more stable, synthetic organic molecules. The products we develop and produce are very sensitive to the production process. Even a slight variation in processing time or temperature can render the product unusable. The complexity and instability of biopharmaceutical products require specialized technology and expertise for development, production and analysis. Our primary development services are: - research and development of sterile product formulations; - test method development and validation; - process design and manufacturing validation; - regulatory and compliance consulting; - preparation of clinical trial and toxicology materials; - container-closure system design; and - accelerated and ongoing studies of product stability. We received ISO (International Organization for Standardization) 9001 certification in June 1996. This certification demonstrates our conformance with the established international quality management standards for product design, development, production, inspection and testing. We believe that ISO 9001 certification is important in attracting domestic and international customers. We intend to provide our services to more pharmaceutical and biotechnology companies in the future. We believe that increasing our development and production capabilities will help us achieve this goal. We have the capacity for these increases in our newly renovated 70,000 square foot sterile pharmaceutical production facility, which the FDA has inspected. However, we will need to purchase additional equipment for this facility in order to expand our services. We do not currently have sufficient funds to make these equipment purchases. We believe the following factors allow us to provide competitive, cost-effective contract services to the pharmaceutical and biopharmaceutical industries: - our established experience and expertise; - ISO 9001 certification; - increased capacity provided by our facility; and - our ability to offer a broad range of drug development and production services. Our executive offices are at 1111 South Paca Street, Baltimore, Maryland 21230, and our telephone number is (410) 843-5000. RISK FACTORS YOU SHOULD CAREFULLY CONSIDER THE FOLLOWING RISKS BEFORE YOU DECIDE TO BUY OUR COMMON STOCK. OUR BUSINESS, FINANCIAL CONDITION OR OPERATING RESULTS MAY SUFFER IF ANY OF THE EVENTS DESCRIBED IN THE FOLLOWING RISK FACTORS ACTUALLY OCCUR. THERE MAY BE ADDITIONAL RISKS THAT WE ARE NOT CURRENTLY ABLE TO IDENTIFY. THESE RISKS MAY ALSO ADVERSELY AFFECT OUR BUSINESS, FINANCIAL CONDITION OR OPERATING RESULTS. IF ANY OF THE EVENTS WE HAVE IDENTIFIED OR THOSE THAT WE CANNOT NOW IDENTIFY OCCUR, THE TRADING PRICE OF OUR COMMON STOCK COULD DECLINE, AND YOU MAY LOSE ALL OR PART OF THE MONEY YOU PAID TO BUY OUR COMMON STOCK. IF WE CANNOT EXPAND OUR PRODUCTION EQUIPMENT, WE MAY NOT BE ABLE TO GROW OUR BUSINESS. The equipment we currently use has limited production capacity. Our existing equipment allows us to conduct only limited production runs. We will need to acquire manufacturing equipment capable of larger production runs if we are to increase our customer base. This equipment is very expensive. We do not currently have a source of funding to acquire it. If we cannot acquire this equipment, we will not be able to produce products in larger runs. Therefore, we will not be able to grow our business substantially without more equipment. BECAUSE WE CURRENTLY OPERATE UNDER SHORT TERM AGREEMENTS, WE NEED TO MAINTAIN OR INCREASE THE NUMBERS OF AGREEMENTS WE HAVE TO GROW OUR BUSINESS. We receive most of our business under individual purchase orders and short term agreements with our customers. Therefore, we have no guaranteed or long-term revenues. We need to continue to successfully negotiate an increased number of purchase orders and contracts with a larger number of clients to increase our revenues. If we fail to maintain our current rate of incoming orders, our revenues and profits will decline. If we fail to obtain more purchase orders or contracts, we cannot grow our business. WE FACE SIGNIFICANT COMPETITION FROM PHARMACEUTICAL COMPANIES AND OTHERS WHICH MAY CAUSE US TO LOWER PRICES OR LOSE BUSINESS. We compete directly with several pharmaceutical product development organizations, contract manufacturers of biopharmaceutical products and university research laboratories. Most companies who produce biopharmaceutical products do not engage in product development. Most companies who provide product development services do not have the equipment or expertise to manufacture products. However, many of our competitors, particularly large established pharmaceutical and biotechnology companies, have many more resources than we do. If any of these competitors, or new ones, decide to provide the same services that we provide at lower prices, we may be forced to lower our prices or lose business. If this happens, our revenues and profitability will decrease. Because many of our competitors have greater financial resources, they would be able to sustain these pricing pressures better than we could. We are a small company with limited financial resources. Therefore, we might be forced to go out of business if we face prolonged price competition. IF WE FAIL TO MEET GOVERNMENTAL REGULATIONS, WE MAY NOT BE ABLE TO SELL OUR SERVICES. We must ensure that our products and services continuously comply with strict requirements designed to ensure the quality and integrity of pharmaceutical products. These requirements include the U.S. Federal Food, Drug and Cosmetic Act and FDA-administered Current Good Manufacturing Practices (known as cGMP) regulations. These regulations apply to all phases our business, including the following: - drug testing and manufacturing; - record keeping; - personnel management; - management and operations of facilities and equipment; - control of materials, processes and laboratories; and - packaging, labeling and distribution. -2- To date, we have been able to comply with these governmental regulations. However Congress or the FDA could impose stricter regulations in the future. We have a small staff of persons with FDA expertise. Therefore, we could have difficulty in quickly changing our methods to comply with stricter regulations. If we fail to comply with the FDA's regulations, the FDA can disqualify any data we collect in our product development process and terminate our ongoing research. If we violate the FDA's regulations, we could face additional regulatory sanctions. In severe cases, the FDA could close our facilities. If the FDA disqualified our data or closed our facilities, even for a short period of time, our reputation could be severely damaged. This would probably make it difficult for us to obtain new purchase orders and contracts. If we could not obtain new purchase orders and contracts, we could go out of business. IF WE FACE LIABILITY FOR ENVIRONMENTAL RISKS AND HAZARDOUS MATERIALS USED IN OUR PROCESSES, DAMAGES MAY EXCEED OUR FINANCIAL RESOURCES. We use controlled hazardous materials in our production and research and development processes. We must comply with many laws and regulations governing the use, manufacture, storage, handling and disposal of these materials. We may be liable for any damages from contamination or injury caused by these hazardous materials. This kind of liability could exceed our financial resources, which could force us to go out of business. WE MUST COMPLY WITH VERY STRICT ENVIRONMENTAL REGULATIONS WHICH MAY CHANGE AND BECOME TOO EXPENSIVE FOR US TO CONTINUE OPERATIONS. We have no control over changes to environmental laws and regulations. If the government passes new laws and regulations or changes existing ones, we may have to incur significant expenses to comply with them. These costs could exceed our available financial resources. If the government changes existing environmental laws and regulations in a way that significantly increases our cost to comply with them, we could become unprofitable and possibly go out of business. IF OUR CUSTOMERS STOP OUTSOURCING THEIR DEVELOPMENT AND MANUFACTURING, WE COULD GO OUT OF BUSINESS. We receive most of our business from customers in the pharmaceutical, biotechnology and medical device industries who have decided to outsource their: - product research and development; - contract manufacturing of sufficient products to allow clinical trials and testing; and - contract manufacturing of products for commercial sale. The industries our customers operate in may experience economic declines. This could cause our customers to stop outsourcing their development, testing and manufacturing. Our customers may also decide to stop outsourcing some of their activities as a way of reducing their development or manufacturing costs. If this happens, we would lose a major source of revenues, and we might have to go out of business. IF WE CANNOT ATTRACT AND RETAIN HIGHLY QUALIFIED SCIENTIFIC AND MARKETING PROFESSIONALS, WE MAY NOT BE SUCCESSFUL IN OUR BUSINESS. We depend on our executive officers and other members of our management team, as well as our scientists and marketing personnel. Generally, our employment agreements with key employees have terms of only two years. If we fail to renew these contracts we may lose our key employees. To grow our business, we will need to add highly skilled scientists and marketing professionals. We face intense competition for highly qualified scientists and marketing professionals because of a shortage of qualified people. Many of our competitors have greater resources and may be able to offer more attractive compensation packages. We may not be able to retain our existing key personnel or attract and retain enough additional or replacement personnel to support our business. If we cannot, we may not be able to operate our existing business properly or grow our business. IF A USER OF ONE OF OUR PRODUCTS SUES US, WE MAY NOT HAVE ENOUGH RESOURCES TO CONTINUE OPERATIONS. The public uses some of the products we produce even though we do not market or sell products directly to the public. Therefore, we face liability for personal injury or death to people who use these products. We may -3- have to pay substantial damages or incur substantial defense costs in connection with a claim of personal injury or death. We may not be repaid under indemnity agreements we have with our customers. Our liability may exceed the amount of our insurance or our customer's indemnity of us. If this happens, we may have to go out of business. We currently maintain product liability insurance of only $1,000,000 per claim and $2,000,000 for all claims in a single year to cover these risks. IF OUR OPERATING RESULTS AND FINANCIAL PERFORMANCE FLUCTUATE, THE MARKET PRICE OF OUR COMMON STOCK MAY FLUCTUATE. Our revenues and operating results have varied substantially from quarter to quarter during the past several years. For example, we incurred net losses during all of our 1999 fiscal year and realized net income of only $111,777 in the first quarter of our 2000 fiscal year. We expect continued quarterly fluctuations based on such factors as: - the timing of our customers' beginning, ending or canceling large contracts with us; - the timing of our invoices to customers under different contracts; - when we incur expenses for facilities and equipment; and - the profit margins from the types of work we perform in any given quarter. For these reasons, we believe that you should not rely on quarterly comparisons of our financial results to predict our future performance. Also, fluctuations in our quarterly results may affect the market price of our common stock for reasons unrelated to our longer term potential. IF WE EXPERIENCE PROBLEMS RELATED TO YEAR 2000 ISSUES, IT COULD DISRUPT OUR ABILITY TO OBTAIN SUPPLIES OR PAYMENTS. Many computer systems and software products accept only two-digit year entries in the date code field. Consequently, on January 1, 2000, these systems could fail or malfunction because they may not be able to distinguish 21st century dates from 20th century dates. Our computer systems are now Year 2000 certified. However, we cannot be sure our customers' and vendors' systems will not fail. If this happens, we may be unable to obtain supplies from our vendors or payment from our customers until the systems are corrected. This could cause a material disruption in our revenues and cause our profitability to decrease substantially until our vendors and customers can correct their systems.

PLAN OF DISTRIBUTION The selling stockholders may offer their shares to the public from time to time after the date of this prospectus. We anticipate that the selling stockholders may sell all or a portion of their shares from time to time through the Nasdaq National Market and to or through one or more broker-dealers at then current market prices. The selling stockholders may also make negotiated sales directly or though one or more broker-dealers. Broker-dealers participating in these types of transactions may receive compensation in the form of discounts or commissions (including, without limitation, customary brokerage commissions) from the selling stockholders effecting such sales. The selling stockholders and any broker-dealers who act in connection with sales of our common stock may be deemed to be "underwriters" as that term is defined in the Securities Act of 1933. -5- The selling stockholders are responsible for all discounts and selling commissions (if any), fees and expenses of their counsel and other advisors, and any other expenses they incur by selling their shares. We agreed to pay the registration fee to the SEC, the listing fee to Nasdaq and the fees and expenses of our counsel and accountants.
