PROSPECTUS SUMMARY

The following summary is qualified in its entirety by the more detailed information, including "Risk Factors" and the Company's Consolidated Financial Statements and related notes thereto, appearing elsewhere in this Prospectus. Except as otherwise noted, all information in this Prospectus, including financial information, share and per share data: (i) reflects the conversion of all of the Company's outstanding Convertible Preferred Shares (the "Convertible Preferred Shares") into Common Shares prior to the completion of this offering;
(ii) assumes no exercise of the Underwriters' over-allotment option; and (iii) reflects a 4.514 for 1 share split to be effected prior to the completion of this offering. Terms used but not otherwise defined herein are defined in the Glossary included herein.

THE COMPANY

The Company is a contract research organization providing research and development resources through both its services and products to many of the leading pharmaceutical, medical device and biotechnology companies in the world. Founded in 1974, the Company has over 23 years of experience in developing products and methodologies to support the analytical chemistry requirements of the drug discovery process. At its inception, the Company focused on providing new products and procedures which facilitated research progress at client sites. Recently, pharmaceutical companies have experienced increasing pressures to bring products to market on a cost-effective and accelerated basis. Accordingly, many clients have requested the Company to carry out proprietary projects at the Company's facilities. As a result, the Company now derives its revenues from (i) research services provided to clients and (ii) the sale of its analytical instruments and other products. The Company believes that among contract research organizations that provide in house statistical, clinical, and medical services, it is the only one that designs and sells analytical instrumentation products and, on the analytical instrument side, it is one of very few firms that maintains a separate business for contract analytical services. The Company intends to continue to take advantage of this unique industry niche.

The Company's services are marketed to pharmaceutical and other biotechnical companies involved in later stages of drug testing and the Company's products are marketed to both public and private research organizations engaged in the early stages of drug development. On the services side, according to the Pharmaceutical Research and Manufacturing Association, in 1997 pharmaceutical and biotechnology companies will spend approximately $18.9 billion worldwide on research and development, of which approximately 18% or $3.4 billion will be outsourced to independent contract service providers such as the Company. On the products side, the Company competes in the $11 billion analytical instrument industry.

Over the past five years, the Company regularly has provided its services and/or products to all of the top 25 pharmaceutical companies in the world, as ranked by 1996 research and development spending. In fiscal 1997, the Company estimates that more than one-third of its total revenue was derived from these companies. As a result of its client focus; reputation for high-quality services and products; capital investment in state-of-the-art instrumentation and facilities; skilled and experienced professional staff; and expertise in performing critical development and support services, the Company believes that it is a value-added partner in solving its clients' complex product development problems.

The Company's operating strategies are derived from a strong base of expertise in analytical chemistry. The Company will continue to (i) enhance the synergy between the Company's services and products; (ii) emphasize high-end testing services; (iii) invest in state-of-the-art instrumentation; (iv) enhance client relationships; and (v) work with large innovator pharmaceutical companies in the development of analytical methods for new drug candidates as early as possible in the drug development process. A portion of the net proceeds from this offering will be used to further implement the Company's operating strategies.

The Company's objective is to continue to grow as a leading provider of high-quality analytical chemistry support services to the worldwide pharmaceutical, medical device and biotechnology industries. In order to continue its growth, the Company intends to leverage its facilities, technological expertise and information systems. The Company believes that it will continue to differentiate itself from its competitors by increasing the array of services and products offered to its clients, further enhancing the Company's reputation of offering

3

a turnkey approach to accurately and quickly meet product development challenges faced by clients. The Company has developed and implemented a business strategy intended to accelerate growth and profitability, consisting of the following five principal elements:

- Increase technical staff to expand the volume of services provided
- Implement a comprehensive marketing and sales program

- Broaden the range of complementary services provided

- Expand geographically in strategic locations
- Identify and effect key acquisitions

The Company was incorporated under the laws of Indiana in 1975. The Company's principal executive offices are located at 2701 Kent Avenue, West Lafayette, Indiana, 47906, and its telephone number is (765) 463-4527.

4

RISK FACTORS

An investment in the Shares offered hereby involves a high degree of risk. Prospective investors should consider carefully the following risk factors, in addition to the other information contained in this Prospectus, prior to making an investment in the Shares.

DEPENDENCE ON CERTAIN INDUSTRIES AND CLIENTS

The Company's revenues are highly dependent on research and development expenditures and compliance testing expenditures by the pharmaceutical, biotechnology and medical device industries and by universities and government research institutions worldwide. Decreases in such expenditures, including those resulting from a general economic decline in these industries, could have a material adverse effect on the Company. The Company has benefited from the growing tendency of companies to engage independent organizations to conduct development and testing projects. Any reduction in the outsourcing of research, development or testing activities, or any reduction in public funding of science and technology could have a material adverse effect on the Company's business, operations and financial condition. There has been substantial consolidation in recent years in the pharmaceutical industry, both in the United States and Europe. It is not possible to assess the impact upon the Company of future pharmaceutical industry consolidation since the effect may depend on an acquiror's inclination to outsource or its existing relationship with the Company or a competitor. See "Business -- Changing Nature of Pharmaceutical Industry."

During 1997, a major United States-based pharmaceutical company and the Company's Japanese distributor accounted for approximately 21% and 12%, respectively, of the Company's total revenues. There can be no assurance that the Company's business will not continue to be dependent on continued relationships with certain clients or distributors or that annual results will not be dependent upon performance of a few large projects. In addition, there can be no assurance that significant clients or distributors in any one period will continue to be significant clients or distributors in other periods. See "Business -- Clients" and "-- Sales and Marketing."

NEED TO ATTRACT, DEVELOP, MANAGE AND RETAIN PROFESSIONAL STAFF

The Company's business is labor intensive and involves the delivery of highly specialized professional services. The Company's future growth and success depends in large part upon its ability to attract, develop, manage and retain highly skilled professional, scientific and technical operating staff. There is significant competition from the Company's competitors as well as from the in-house research departments of pharmaceutical and biotechnology companies and other enterprises for employees with the skills required to perform the services offered by the Company. Although the Company has confidentiality agreements with its scientific and technical operating personnel, the Company does not have in place covenants not to compete that would directly preclude the employees from being employed by a competitor. There can be no assurance that the Company will be able to attract, develop, manage and retain a sufficient number of highly skilled employees in the future or that it will continue to be successful in training, retaining and managing its current employees. The loss of a significant number of employees or the Company's inability to hire sufficient numbers of qualified employees could have a material adverse effect on the Company's business, operations and financial condition. See "Business -- Employees."

DEPENDENCE ON KEY EXECUTIVES

The Company relies to a significant extent on a number of key executives, including Peter T. Kissinger, Ph.D., its President and Chairman of the Board. The Company maintains key man life insurance on Dr. Kissinger in the amount of $1.0 million. The loss of the services of any of the Company's key executives could have a material adverse effect on the Company's business, operations and financial condition.

DEPENDENCE ON AND POSSIBLE ADVERSE EFFECT OF GOVERNMENT REGULATION

The Company's business depends in part on government regulation of the drug development process by the United States and foreign governments. More stringent governmental regulation of the drug development

5

process increases the need for services and products provided or produced by the Company. Recently, legislation has been proposed that would substantially modify the current requirements for FDA administration of the drug and device approval process. Under the proposed legislation, applications for approval of new drugs could be made to private accredited facilities in lieu of the FDA. As a result, the number of clinical trials of new drugs would be reduced and other rules administered by the FDA would be simplified. Any change in the scope of regulatory requirements or the introduction of simplified drug or device approval procedures could adversely affect the Company's business, operations and financial condition.

The Company's revenues are also dependent, in part, upon continued compliance with governmental requirements applicable to facilities and techniques used in the manufacture of products for clinical use and the provision of services. The Company's facilities are subject to scheduled periodic regulatory inspections to ensure compliance with FDA requirements. Failure on the part of the Company to comply with applicable requirements could result in the termination of ongoing research, the discontinuance of selected Company operations, the disqualification of data for submission to regulatory authorities and fines and penalties being assessed against the Company, any of which could have a material adverse effect on the Company's business, operations and financial condition.

The Company's activities are also subject to foreign, federal, state and local laws and regulations governing the use, storage, handling and disposal of hazardous materials and chemicals. If the Company were held liable for an accidental contamination or injury from these materials and chemicals, the Company's business, operations and financial condition could be materially adversely affected. See "Business -- Changing Nature of Pharmaceutical Industry" and "Business -- Government Regulation."

COMPETITION

With respect to its products, the Company primarily competes with several large equipment manufacturers and, with respect to its services, the Company primarily competes against in-house research departments of pharmaceutical and biotechnology companies, universities and teaching hospitals and other full-service CROs. Many of the Company's competitors possess substantially greater capital, technical and other resources than the Company. Competitive factors with respect to the Company's products include quality, reliability and price. CROs generally compete on the basis of previous experience, medical and scientific expertise in specific therapeutic areas, the quality of contract research, the ability to organize and manage large-scale trials on a global basis, medical database management capabilities, the ability to provide statistical and regulatory services, the ability to recruit investigators, the ability to integrate information technology with systems to improve the efficiency of contract research, an international presence with strategically located facilities, financial viability and price. The Company's failure to compete effectively in any one or more of these areas could have a material adverse effect on the Company's business, operations and financial condition. See "Business -- Changing Nature of Pharmaceutical Industry" and "Business -- Competition."

CLIENT CONTRACTS TERMINABLE UPON NOTICE

Generally, the Company's service contracts are terminable by the client upon notice at any time. Contracts may be terminated for a variety of reasons, including the client's decision to forego a particular study, failure of products to satisfy safety requirements and unexpected or undesired product testing results. The loss of business from a significant client or the cancellation of a major contract or series of commitments could have a material adverse effect on the Company's business, operations and financial condition. See "Business -- Contractual Arrangements."

UNCERTAINTY OF INTERNATIONAL MARKETS

In fiscal 1997, approximately 35% of the Company's total revenue was derived from customers located outside the United States. The Company expects to increase its geographical diversification outside the United States, including entering new markets in Asia and South America. These markets tend to be much more volatile than the United States market. Significant governmental, regulatory, political, economic and cultural issues or changes could adversely affect the growth or profitability of the Company's business activities in any

6

such market. In addition, although currently all of the Company's contracts are required to be paid in United States dollars, in the event future contracts were denominated in a foreign currency the Company could be faced with currency fluctuations in the conversion to United States dollars.

DEPENDANCE ON PROPRIETARY TECHNOLOGY; UNPREDICTABILITY OF PATENT PROTECTION

The Company's business is dependent, in part, on its ability to obtain patents in various jurisdictions on its current and future technologies and products, to defend its patents and protect its trade secrets and to operate without infringing on the proprietary rights of others. There can be no assurance that the Company's patents will not be challenged by third parties or that, if challenged, those patents will be held valid. In addition, there can be no assurance that any technologies or products developed by the Company will not be challenged by third parties owning patent rights and, if challenged, will be held to not infringe those patent rights. The expense involved in any patent litigation can be significant. The Company also relies on unpatented, proprietary technology, and there can be no assurance that others will not independently develop or obtain similar products or technologies.

FUTURE CAPITAL REQUIREMENTS MAY BE SIGNIFICANT; UNCERTAINTY OF ADDITIONAL FUNDING

The Company expects capital and operating expenditures to increase over the next several years. Although the Company believes that the net proceeds from this offering, existing cash and cash equivalents and anticipated cash flow from operations will be sufficient to support the Company's operations for the foreseeable future, the Company's actual future capital requirements will depend on many factors, including its future profitability, the rate of its internal growth and the timing, size and terms of acquisitions made by the Company, if any. The Company may require significant additional financing in the future, which it may seek to raise through public or private equity offerings or debt financings. There can be no assurance that additional financing will be available when needed or that, if available, such financing can be obtained on terms favorable to the Company. To the extent the Company raises additional capital by issuing equity securities, ownership dilution to existing shareholders will result and may be substantial. See "Use of Proceeds," "Business -- Growth Strategy" and "Management's Discussion and Analysis of Financial Condition and Results of Operations -- Liquidity and Capital Resources."

RISK RELATED TO GROWTH THROUGH ACQUISITIONS

The Company's growth strategy includes identifying and effecting selected acquisitions. The Company has limited acquisition experience, and growth through acquisition involves numerous risks, including the potential inability of the Company to effectively assimilate the operations of acquired companies, the expenses incurred in connection with failed acquisition attempts, the diversion of management's attention from other business concerns and, in the case of acquisitions of foreign companies, the risks presented by language and cultural barriers and currency exchange rate fluctuations. There can be no assurance that the Company will complete any future acquisitions or that acquisitions, if any, will contribute favorably to the Company's business, operations and financial condition. See "Business -- Growth Strategy."

IMMEDIATE AND SUBSTANTIAL DILUTION

The purchasers of the Shares will experience immediate and substantial dilution of the net tangible book value per share from the initial offering price. See "Dilution."

VOLATILITY OF QUARTERLY OPERATING RESULTS

The Company's results of operations have been and will continue to be subject to quarterly fluctuations, principally as a result of the commencement, completion, cancellation or duration of large contracts, the progress of ongoing contracts, changes in the mix of products and services, the incurrence of significant expenses upon commencement of product or service contracts before any significant revenues are recognized from such activities, and seasonality in the business. For this reason, there is a risk that comparisons of quarterly operating results on a year-to-year basis, or on a quarter-to-quarter basis, will not provide a

7

meaningful indication of future performance. In addition, fluctuations in quarterly results could affect the market price of the Common Shares in a manner unrelated to the longer-term operating performance of the Company.

LIABILITY RISKS RELATED TO PRODUCTS AND THE PROVISION OF SERVICES

Although the Company does not provide products or services directly to the public, its business involves the sale of instruments for use by others and the provision of contract analytical services. It is possible that claims could be made against the Company by either its clients or the customers of its clients for damages suffered as a result of the use of the Company's products or for errors made in the performance of the Company's analytical services. The Company maintains product liability and errors and omissions insurance with respect to these risks, but there can be no assurance that the insurance would cover all risks. The Company also seeks to reduce its exposure through indemnification agreements with its clients. The scope of those agreements may vary from client to client, and the performance of the clients' obligations thereunder are not secured. There can be no assurance that these measures will be adequate to protect the Company from damages resulting from defects in its products or services. See "Business -- Product Liability and Insurance."

MANAGEMENT DISCRETION REGARDING NET PROCEEDS OF THE OFFERING

The Company has not yet allocated a substantial portion of the net proceeds of the offering to specific uses. Accordingly, management will have broad discretion as to the application of the offering proceeds. Pending the Company's use of such proceeds, the net proceeds of the offering will be invested in high-quality, short-term, interest-bearing investment-grade debt securities, certificates of deposit or direct or guaranteed obligations of the United States. It is possible that the return on such investments will be less than that which would be realized were the Company immediately to use such funds for other purposes. See "Use of Proceeds."

CONCENTRATION OF OWNERSHIP

Upon the completion of this offering, certain of the Company's executive officers will beneficially own approximately 35% of the outstanding Common Shares, and certain of the Company's non-employee directors will beneficially own approximately 20% of the outstanding Common Shares. Accordingly, those persons will be in a position to significantly influence the election of the Company's directors and the outcome of corporate actions requiring shareholder approval. This concentration of ownership may have the effect of delaying or preventing a change in control of the Company. See "Management" and "Principal Shareholders."

SHARES ELIGIBLE FOR FUTURE SALE; REGISTRATION RIGHTS

The sale of substantial amounts of the Common Shares in the public market following the offering could have an adverse effect on prevailing market prices of the Common Shares. Immediately after the offering, the 1,500,000 Shares (1,725,000 Shares if the Underwriters' over-allotment option is exercised in full) offered hereby will be freely tradeable without restriction, and approximately 600,000 additional Common Shares will be eligible for sale in the public market pursuant to Rule 144(k) under the Securities Act. All of the Company's directors and executive officers and certain of the Company's shareholders have agreed with the Underwriters not to sell an aggregate of 2,334,592 Common Shares held by them for a period of 180 days from the date of this Prospectus without the prior consent of the Underwriters. After such time, or earlier with the written consent of the Underwriters, those Common Shares will be eligible for sale, subject to the volume and other restrictions under Rule 144 promulgated under the Securities Act. See "Shares Eligible For Future Sale."

The Company also intends to file a registration statement covering the sale of Common Shares reserved for issuance under the Company's stock option plans approximately 30 days following the date of this Prospectus. As of September 30, 1997, there were aggregate options outstanding under the Bioanalytical Systems, Inc. 1990 Employee Incentive Stock Option Plan (the "1990 Employee Option Plan") and the 1990 Bioanalytical Systems, Inc. Outside Director Stock Option Plan (the "1990 Director Option Plan") to

purchase 272,671 Common Shares at a weighted average price of $1.27 per share, of which 236,555 Common Shares were then vested and exercisable. The holders of 171,757 of the options exercisable as of September 30, 1997 have signed Lock-Up Agreements. The Company also may issue and sell up to 95,000 Common Shares under the 1997 Employee Incentive Stock Option Plan (the "1997 Employee Option Plan") and 5,000 Common Shares under the 1997 Outside Director Stock Option Plan (the "1997 Director Option Plan", and together with the 1997 Employee Option Plan, the 1990 Employee Option Plan and the 1990 Director Option Plan, the "Option Plans"). See "Management -- Option Plans," and "Underwriting."

Certain shareholders have the right to require the registration of their Common Shares under the Securities Act at any time subject to certain limitations but those shareholders have agreed not to exercise those rights for a period of 180 days from the date of this Prospectus. See "Description of Capital Stock -- Registration Rights." If those shareholders were to cause a large number of Common Shares to be registered and sold in the public market thereafter, the market price for the Common Shares could be materially adversely affected. Additionally, those shareholders have the right to require the Company to include their Common Shares in any Company-related registration under the Securities Act, and the exercise of these "piggyback" registration rights could have a material adverse effect on the Company's ability to raise capital in the future. See "Certain Transactions."

NO PRIOR MARKET; POTENTIAL STOCK PRICE VOLATILITY

Prior to this offering, there has been no public market for the Common Shares and there can be no assurance that an active trading market will develop or be sustained after this offering. The initial public offering price will be determined through negotiations between the Company and the Underwriters and may not represent prices that will prevail in the trading market. See "Underwriting."

The market price of the Common Shares could be subject to wide fluctuations in response to variations in operating results from quarter to quarter, changes in earnings estimates by analysts, market conditions in the industry and general economic conditions. See "Risk Factors -- Volatility of Quarterly Operating Results." Furthermore, the stock market has experienced significant price and volume fluctuations unrelated to the operating performance of particular companies. These market fluctuations may have an adverse effect on the market price of the Common Shares. Following the offering, the Company will have approximately 4.5 million Common Shares outstanding, of which approximately 2.0 million Common Shares could be considered to be part of the "float." Based on the anticipated initial public offering price of between $9.00 and $11.00 per share, the market capitalization of the Company would be approximately $40.5 million to $49.5 million. As a result of the small "float" and market capitalization, the Company's Common Shares will be subject to volatility. The price volatility of the Common Shares could be accentuated by quarterly fluctuations in earnings. See "Risk Factors -- Volatility of Quarterly Operating Results."

POSSIBLE ISSUANCE OF PREFERRED SHARES

The Board of Directors of the Company has the authority to issue preferred shares in the future without further shareholder approval and upon such terms and conditions, and having such rights, privileges and preferences, as the Board of Directors may determine. The issuance of preferred shares, while providing desirable flexibility in connection with possible acquisitions and other corporate purposes, could adversely affect the market price of the Common Shares and could have the effect of making it more difficult for a third party to acquire, or of discouraging a third party from acquiring, a majority of the outstanding voting securities of the Company. The Company has no present plans to issue any preferred shares. See "Description of Capital Stock."

NO CASH DIVIDENDS

The Company has never paid any cash dividends to holders of its Common Shares and does not anticipate paying any cash dividends in the foreseeable future, but intends instead to retain any future earnings for reinvestment in its business. Any future determination as to the payment of dividends will be made at the discretion of the Board of Directors of the Company and will depend upon the Company's operating results, financial condition, capital requirements, general business conditions and such other factors as the Board of Directors deems relevant. See "Dividend Policy."

USE OF PROCEEDS

The net proceeds to the Company from the sale of the 1,500,000 Shares offered hereby are estimated to be $13.4 million ($15.5 million if the Underwriter's over-allotment option is exercised in full), assuming an initial public offering price of $10.00 per share (the midpoint of the range set forth on the cover page of this Prospectus) and after deducting the underwriting discounts and commissions and estimated offering expenses payable by the Company. The Company intends to utilize approximately $5.8 million to repay bank indebtedness and approximately $3.0 million to purchase laboratory equipment. The Company also intends to utilize a portion of the net proceeds to hire additional technical staff and to upgrade its information systems. These expenditures will primarily supplement and expand capabilities for existing services offered to clients. In addition, the Company intends to use a portion of the proceeds from the offering to expand its present facilities as well as to fund future geographic expansion. The Company will use the remainder of the net proceeds for working capital and other general corporate purposes, including potential acquisitions. Pending such uses, the Company intends to invest the remaining proceeds of the offering in high-quality, short-term, interest-bearing, investment-grade debt securities, certificates of deposit or direct or guaranteed obligations of the United States.

As part of its business strategy, the Company reviews many acquisition candidates in the ordinary course of business, although the Company currently has no agreements or arrangements in place with respect to any future acquisition. There can be no assurance that the Company will complete any acquisitions.

DIVIDEND POLICY

The Company has never paid cash dividends on its Common Shares and does not anticipate paying any cash dividends in the foreseeable future. The Company currently intends to retain any future earnings to develop and expand its business. The Company is currently restricted from paying cash dividends under the terms of its lines of credit without the prior written consent of the bank.

DILUTION

The net tangible book value of the Company as of September 30, 1997 was approximately $6.7 million or $2.22 per share after giving effect to the conversion of the outstanding Convertible Preferred Shares into Common Shares and the 4.514 for 1 share split to be effected prior to the issuance of the Shares offered hereby. The net tangible book value per share is equal to the book value of the Company's total tangible assets less its total liabilities, divided by the total number of Common Shares outstanding. After giving effect to the sale by the Company of 1,500,000 Shares offered hereby at an assumed public offering price of $10.00 per share (resulting in estimated net proceeds of $13.4 million after deducting the estimated underwriting discounts and commissions and estimated offering expenses), the net tangible book value of the Company as of September 30, 1997 would be approximately $20.0 million, or $4.46 per share. This represents an immediate increase of $2.24 per share to existing shareholders and an immediate dilution of $5.54 per share to new investors. The following table illustrates this per share dilution:

Initial public offering price per share.....................             $10.00

To the extent that the Underwriters' over-allotment option is exercised in full, the net tangible book value of the Company at September 30, 1997 would have been approximately $22.2 million, or $4.69 per share, representing an immediate increase in net tangible book value per share of $2.47 to existing shareholders and an immediate dilution of $5.31 per share to new investors.

The following table summarizes, as of September 30, 1997, the differences in the number of Common Shares purchased from the Company, the total consideration paid to the Company and the average price per share paid by the existing shareholders and by the new investors with respect to the Shares offered hereby, assuming an initial public offering price of $10.00 per share and before deduction of estimated underwriting discounts and commissions and estimated offering expenses:

(1) The above computations exclude options outstanding at September 30, 1997 to purchase a total of 272,671 Common Shares at a weighted average exercise price of $1.27 per share. To the extent these options are exercised, there will be further dilution to new investors. See "Capitalization," "Management -- Option Plans" and Note 6 of Notes to Consolidated Financial Statements.

The following discussion and analysis should be read in conjunction with Selected Consolidated Financial Data and the Company's Consolidated Financial Statements and notes thereto included elsewhere in this Prospectus. In addition to the historical information contained herein, the discussions in this Prospectus may contain forward-looking statements that involve risks and uncertainties. The Company's actual results could differ materially from those discussed herein. Factors that could cause or contribute to such differences include, but are not limited to, those discussed below and in the section entitled "Risk Factors," as well as those discussed elsewhere in this Prospectus.

OVERVIEW

The Company provides a broad range of value-added products and services focused on chemical analysis to the worldwide pharmaceutical, medical device and biotechnology industries. The Company's customer-focused approach and its high quality products and services enable it to serve as a value-added partner in solving complex scientific problems by providing cost-effective results to its customers on an accelerated basis. Founded in 1974 in Lansing, Michigan and relocated to West Lafayette, Indiana in 1975, the Company has experienced growth primarily through internal expansion, supplemented by strategic acquisitions. As part of its internal growth strategy, the Company has developed technical specialties in such areas as chromatography, electrochemistry, in vivo sampling and mass spectrometry. The Company's growth has strategically positioned it to take advantage of globalization in the marketplace and to provide new services and areas of technical expertise to its customers. During this phase, the Company has been continuously profitable since 1987.

Throughout its history, the Company has taken steps to position itself as a global leader in the analytical chemistry field. Development of the Company's infrastructure began in 1975 when it established relationships with several customers and multiple international distributors. In 1981, the Company increased its sphere of influence to include Japan with the creation of BAS Japan, an independent distributor. In 1988, the Company enhanced its computer software expertise by acquiring Interactive Microware Inc. in State College, Pennsylvania. In 1990, the Company began offering contract services to customers that lacked the time or expertise to perform certain analyses using the Company's analytical products. In 1991, the Company further expanded its global presence by establishing an office in Brussels, Belgium, and in 1995, the Company acquired a distributor, BAS Technicol Ltd., to further solidify its presence in the United Kingdom. While the Company derives a significant portion of its revenues from customers in Asia, the Company does not expect that the recent economic downturn in certain Asian markets will have a material adverse impact on its financial condition in the short or long term, because the Company does not derive a significant amount of its total revenue from these markets.

Revenues are derived principally from (i) the sale of the Company's analytical instruments and other products, and (ii) analytical services provided to customers. Both methods of generating revenue utilize the Company's ability to identify, isolate and resolve client problems relating to the separation and quantification of individual substances in complex mixtures. The Company's analytical products are sold primarily to pharmaceutical firms and research organizations. The Company supports the pharmaceutical industry by focusing on analytical chemistry for biomedical research, diagnostics, electrochemistry and separations science. Principal customers include scientists engaged in drug metabolism studies, as well as those engaged in basic neuroscience research. The Company was the first to commercialize the liquid chromatography and electrochemistry technology which is now the worldwide standard for the determination of neurotransmitter substances. Research products include in vivo sampling devices, reagent chemicals, electrochemical apparatus and sensors.

Revenue from the sale of the Company's products and the related costs are recognized upon shipment of the products to customers. The Company's pharmaceutical service contracts generally have terms ranging from several months to several years. A portion of the contract fee is generally payable upon receipt of the initial samples with the balance payable in installments over the life of the contract. The contracts are broken down into discrete units of deliverable services for which a fixed fee for each unit is established, and revenue

14

and related direct costs are recognized as specific contract terms are fulfilled under the percentage of completion method utilizing units of delivery. The termination of a contract results in no material adjustments to revenue or direct costs previously recognized, and the Company is entitled to payment for all work performed through the date of notice of termination and all costs associated with termination of a contract.

The Company's management believes that fluctuations in the Company's quarterly results are caused by a number of factors, including the Company's success in attracting new business, the size and duration of service contracts, the timing of its client's decisions to enter into new contracts, the cancellation or delays of on-going contracts, the timing of acquisitions and other factors, many of which are beyond the Company's control. See "Risk Factors -- Volatility of Quarterly Operating Results."

Year ended September 30, 1997 Compared with Year ended September 30, 1996

Total revenue for the year ended September 30, 1997 increased 16.6% to approximately $14.9 million from approximately $12.8 million in the year ended September 30, 1996. The net increase of approximately $2.1 million related primarily to increased revenue from services, which increased to approximately $5.0 million in the year ended September 30, 1997 from approximately $3.7 million in the year ended September 30, 1996 as a result of the expansion of types and volume of services provided by the Company. During this same period, product revenue increased to approximately $9.9 million for the year ended September 30, 1997 from approximately $9.1 million for the year ended September 30, 1996 primarily as a result of increased penetration in the electrochemistry and the liquid chromatography market.

Costs of revenue increased 17.7% to approximately $6.3 million for the year ended September 30, 1997 from approximately $5.4 million for the year ended September 30, 1996. This increase of approximately $952,000 was largely due to the hiring of additional support staff in the services unit. Costs of revenue for the Company's products decreased to 33.6% as a percentage of product revenue for the year ended September 30, 1997 from 35.4% of product revenue for the year ended September 30, 1996, due to a change in product mix.

15

Costs of revenue for the Company's services increased to approximately 59.8% as a percentage of services revenue for the year ended September 30, 1997 from approximately 58.2% of services revenue for the year ended September 30, 1996 due to an increase in services support staff.

Selling expenses for the year ended September 30, 1997 increased 7.3% to approximately $4.2 million from approximately $3.9 million during the year ended September 30, 1996 due to increased commissions on foreign sales. Research and development expenses for the year ended September 30, 1997 increased 10.1% to $1.6 million from approximately $1.4 million for the year ended September 30, 1996 due to the development of the in vitro product line. General and administrative expenses for the year ended September 30, 1997 increased 20.1% to approximately $1.6 million from approximately $1.4 million for the year ended September 30, 1996, primarily as a result of increased property taxes incurred in connection with the Company's purchase and construction of additional facilities.

Other income (expense), net, was approximately $(75,000) in the year ended September 30, 1997 as compared to approximately $(18,000) in the year ended September 30, 1996 as a result of a reduction of interest income due to a reduction in cash and cash equivalents resulting from the redemption of Redeemable Preferred Shares owned by the Venture Funds in accordance with their terms.

The Company's effective tax rate for 1997 was 37.7% as compared to 41.4% for fiscal 1996. This decrease was primarily due to utilization of the research and development tax credit.

Year ended September 30, 1996 Compared with Year ended September 30, 1995

Total revenue for the year ended September 30, 1996 increased 3.6% to approximately $12.8 million from approximately $12.4 million in the year ended September 30, 1995. The net increase of approximately $400,000 related to increased revenue from services, which increased to approximately $3.7 million in the year ended September 30, 1996 from approximately $2.7 million in the year ended September 30, 1995 as a result of the expansion of types and volume of services provided by the Company. During this same period, product revenue decreased to approximately $9.1 million for the year ended September 30, 1996 from approximately $9.6 million for the year ended September 30, 1995 primarily as a result of increased industry competition in the liquid chromatography market.

Costs of revenue increased 1.6% to approximately $5.4 million for the year ended September 30, 1996 from approximately $5.3 million for the year ended September 30, 1995. This increase of approximately $100,000 was due to the hiring of additional support staff in the services unit. Costs of revenue for the Company's products decreased to 35.4% as a percentage of product revenue for the year ended September 30, 1996 from 35.8% of product revenue for the year ended September 30, 1995, due to a change in product mix. Costs of revenue for the Company's services decreased to approximately 58.2% as a percentage of service revenue for the year ended September 30, 1996 from approximately 67.3% of services revenue for the year ended September 30, 1995 due to an increase in the level of services revenue.

Research and development expenses for the year ended September 30, 1996 increased 26.7% to $1.4 million from approximately $1.1 million for the year ended September 30, 1995 due to the development of the in vitro product line. General and administrative expenses for the year ended September 30, 1996 increased 11.6% to approximately $1.4 million from approximately $1.2 million for the year ended September 30, 1995, primarily as a result of increased property taxes incurred in connection with the Company's purchase and construction of additional facilities.

Other income (expense), net, was approximately $(18,000) in the year ended September 30, 1996 as compared to approximately $111,000 in the year ended September 30, 1995 as a result of a reduction in interest income due to a reduction in cash and cash equivalents resulting from the redemption of Redeemable Preferred Shares owned by the Venture Funds in accordance with their terms.

16

The Company's effective tax rate for 1996 was 41.4% as compared to 38.5% for fiscal 1995. This increase was due, in part, to operating losses from operations in the United Kingdom for which there is no corresponding income tax deduction and to increased state income taxes.

LIQUIDITY AND CAPITAL RESOURCES

Since its inception, the Company's principal sources of cash have been cash flow generated from operations and funds received from venture capital investments, the most recent of which was a $2.0 million financing completed in March 1991. At September 30, 1997, the Company had cash and cash equivalents of approximately $160,000, compared to cash and cash equivalents of approximately $600,000 at September 30, 1996. The decrease in cash resulted primarily from increased capital expenditures made to expand the Company's facilities and operations. The expansion was partially financed by cash provided by operating activities, and a $5.0 million credit facility.

The Company's net cash provided by operating activities was approximately $842,000 for the year ended September 30, 1997. Cash provided by operations during the year ended September 30, 1997 consisted of net income of approximately $684,000 plus non-cash charges of approximately $584,000 partially offset by a net increase of approximately $426,000 in operating assets and liabilities. The most significant increase in operating assets related to trade accounts receivable, which increased to approximately $3.0 million at September 30, 1997 from approximately $1.6 million at September 30, 1996, due primarily to sales growth.

Cash used by investing activities increased to approximately $4.0 million for the year ended September 30, 1997 from approximately $3.2 million for the year ended September 30, 1996, primarily as a result of the Company's purchase and construction of additional facilities. Cash provided by financing activities for the fiscal 1997 was approximately $2.7 million due to an increase in the Company's long and short term debt and offset by the redemption of Redeemable Preferred Shares in accordance with their terms.

The Company's net cash provided by operating activities was approximately $301,000 for the year ended September 30, 1996, resulting from approximately $400,000 of net income and reduced by a net increase in operating assets and liabilities which was partially offset by non-cash charges. Trade accounts receivable remained relatively constant at approximately $1.6 million at September 30, 1996 as compared to September 30, 1995.

Cash used by investing activities increased to approximately $3.2 million for fiscal 1996 from approximately $1.3 million for fiscal 1995, primarily as a result of the Company's purchase and construction of additional facilities. Cash provided by financing activities for fiscal 1996 was approximately $1.7 million due to an increase in the Company's long term debt incurred for the facilities expansion and offset by the redemption of Redeemable Preferred Shares in accordance with their terms.

Total expenditures by the Company for property and equipment were approximately $1.3 million $3.2 million and $4.1 million in fiscal 1995, 1996 and 1997, respectively. Expenditures made in connection with the expansion of the Company's operating facilities and purchases of laboratory equipment account for the largest portions of these expenditures. The Company anticipates increased levels of capital expenditures in fiscal 1998 and fiscal 1999. The increased capital investments relate to the completion of the renovation and construction of the additional facilities and the purchase of additional laboratory equipment corresponding to anticipated increases in research services to be provided by the Company. The Company also expects to make other investments to expand its operations, through internal growth and strategic acquisitions, alliances and joint ventures. However, the Company currently has no firm commitments for capital expenditures other than in connection with the expansion of the Company's facilities.

Based on its current business activities, the Company believes that cash generated from its operations, amounts available under its existing bank lines of credit and credit facility and the net proceeds from this offering will be sufficient to fund the Company's working capital and capital expenditure requirements for the next few years.

The Company has a bank line of credit agreement which expires March 1, 1998 and allows borrowings of the lesser of 50.0% of inventories plus 80.0% of qualified accounts receivable or $2.2 million. Interest is

17

charged at the prime rate plus .25% (8.75% at September 30, 1997). At September 30, 1997, the collateral base for this line of credit resulted in borrowing availability of approximately $2.2 million of which $200,000 was outstanding at September 30, 1997. The line is collateralized by inventories and accounts receivable. The Company has a second line of credit agreement with the same bank for capital expenditures which expires March 1, 1998 and allows borrowings of the lesser 80% of capital expenditures or $1,000,000. Interest is charged at the prime rate plus .25% (8.75% at September 30, 1997). At September 30, 1997, $315,377 was outstanding on this line. The line is collateralized by fixed assets, inventories and accounts receivable. The Company has entered into negotiations with the bank to increase the amounts available under these lines of credit and extend the expiration dates upon completion of the sale of the Shares offered hereby, although there can be no assurance that such negotiations will be successful.

During 1996, the Company entered into a credit facility for up to $5.0 million for the purchase and renovation of an adjacent building. At maturity of this facility on January 31, 1998, the loan may be converted to a five year term loan based upon a 20 year amortization funding on a conventional commercial mortgage basis or with fixed principal payments plus interest. Interest is charged at the prime rate plus .25% (8.75% at September 30, 1997). This credit facility is collateralized by substantially all of the Company's property and equipment. The agreement contains certain covenants which, among other things, require the Company to maintain minimum levels of tangible net worth and debt service coverage.

RECENT DEVELOPMENT

On October 31, 1997, the Company acquired all of the outstanding capital stock of Vetronics, Inc. ("Vetronics"), which manufactures, markets and sells, electrocardiograph and vital sign monitors for small to midsize animals. The total purchase price consisted of $200,000 in cash, $150,000 in notes payable on July 1, 1998 and a contingent amount to be based upon the profitability of sales from products manufactured by Vetronics during the next two years. The Company believes that the addition of these products will enhance its position as a producer of physiology instrumentation.

INFLATION

To date, the Company believes that the effects of inflation have not had a material adverse effect on its business, operations or financial condition.

NEW ACCOUNTING PRONOUNCEMENTS

In July 1997, the Financial Accounting Standards Board (the "FASB") issued Statement No. 131 ("SFAS 131"), "Disclosures about Segments of an Enterprise and Related Information." Under SFAS 131, the Company will report financial and descriptive information about its operating segments. SFAS 131 is effective for fiscal years beginning after December 15, 1997. The Company plans to adopt SFAS 131 on October 1, 1998. The Company has not yet evaluated the impact of adoption of SFAS 131.

In June 1997, the FASB issued Statement of Financial Accounting Standards No. 130 ("SFAS 130"), "Reporting Comprehensive Income." SFAS 130 establishes standards for reporting and display of comprehensive income in the financial statements. SFAS 130 is effective for fiscal years beginning after December 15, 1997. The Company plans to adopt SFAS 130 on October 1, 1998. The Company has not yet evaluated the impact of SFAS 130.

In February 1997, the FASB issued Statement of Financial Accounting Standards No. 128, "Earnings per Share," which replaces the presentation of primary earnings per share ("EPS") with basic EPS and replaces fully diluted EPS with diluted EPS. It also requires dual presentation of basic and diluted EPS on the face of the income statement for all entities with complex capital structures and requires a reconciliation of the components of the basic EPS computation to the components of the diluted EPS computation. SFAS No. 128 is effective for both interim and annual periods ending after December 15, 1997. Earlier adoption is not permitted. Upon adoption, all prior-period EPS data presented will be restated. The Company does not anticipate the adoption of SFAS

No. 128 to have a significant effect on EPS.

BUSINESS

COMPANY OVERVIEW

The Company is a contract research organization providing research and development resources to many of the leading pharmaceutical, medical device and biotechnology companies in the world. The Company offers an efficient, variable-cost alternative to its clients' internal product development, compliance and quality control programs. Founded in 1974, the Company initially focused primarily on providing new products and procedures which facilitated research progress at client sites. Recently, as a result of increasing pressures to bring products to market on a cost-effective and accelerated basis, many clients have requested the Company to carry out proprietary projects at the Company's facilities. As a result, the Company now derives its revenues from both the sale of its analytical instruments and other products as well as research services provided to customers. The Company provides a broad array of both value-added products and services focused on chemical analysis, allowing its clients to perform their R&D functions either "in-house" or at the Company. The Company believes that among CROs that provide statistical, clinical, and medical services, the Company is the only one that designs and sells analytical instrumentation. Within the analytical instruments business, the Company believes that it is one of very few firms to maintain a separate business unit devoted to contract analytical services under the regulatory framework of GLPs and GMPs.

The Company's products and services combine basic research with diagnostic and therapeutic experience. One consequence of the restructuring of the healthcare industry is the greater reliance on outsourcing research services for both clinical trials and formulation development. The Company is capable of supporting the analytical needs of researchers and clinicians, from small molecule drugs and hormones through large biomolecules such as proteins. The Company's scientists have the skills necessary in instrumentation, chemical reagents and computer software to make the products and services it provides increasingly valuable to the worldwide pharmaceutical, medical device and biotechnological industries.

Over the past five years, the Company regularly has provided its products and/or services to all of the top 25 pharmaceutical companies in the world, as ranked by 1996 research and development spending. In fiscal 1997, the Company estimates that more than one-third of its total revenue was derived from these companies. As a result of its (i) client focus, (ii) reputation for high-quality services and products, (iii) capital investment in state-of-the art instrumentation and facilities, (iv) skilled and experienced professional staff, and (v) expertise in performing critical development and support services, the Company believes that it is a value-added partner in solving its clients' complex product development problems.

The Company designs, manufactures and markets a broad range of products and related scientific procedures that detect and quantify the presence of chemicals in certain substances. On the products side, the Company competes in the $11 billion analytical instrument industry. The Company's focus, however, is not on marketing hardware and software, but rather on solutions to challenging analytical problems where the Company can utilize its talented personnel to provide a total solution not generally available from hardware-focused competitors. The Company's products utilize state-of-the-art scientific technology, including liquid chromatography, electrochemistry and in vivo sampling instrumentation. The Company's analytical instruments are sold primarily to pharmaceutical firms and research organizations. Principal clients include scientists engaged in drug metabolism studies, as well as scientists engaged in basic neuroscience research.

The Company provides a wide variety of services to pharmaceutical companies, medical device manufacturers, medical research centers, academic institutions and others. These analytical services support screening and pharmacological testing, toxicology/safety testing, formulation development, laboratory testing, regulatory and compliance consulting and quality control testing. The Company began providing services primarily in response to requests from customers who had used or were using the Company's products. To reduce overhead and speed drug approval requests through the FDA, pharmaceutical companies are contracting increasing amounts of their analytical work to outside firms like the Company. The Pharmaceutical Research and Manufacturing Association estimates that in 1997, pharmaceutical and biotechnology companies will spend approximately $18.9 billion worldwide on research and development, of which approximately 18%, or $3.4 billion, will be outsourced to independent contract service providers. The Company believes that the trend of outsourcing will continue as a result of drug development pressures, the

19

emphasis on cost containment, patent expirations, consolidation in the pharmaceutical industry, virtual drug company and biotechnology industry growth, the need for technical expertise, the need for data management expertise and the globalization of the pharmaceutical marketplace.

CHANGING NATURE OF PHARMACEUTICAL INDUSTRY

The Company provides products and services on a world wide basis to pharmaceutical, medical device and biotechnology companies, academic institutions and the United States government to facilitate the research and development of drugs and medical devices. The Company's products are marketed generally to both public and private research organizations engaged in the early stages of drug development, while the Company's services are marketed generally to pharmaceutical and other biotechnical companies engaged in later stages of drug testing. The Company competes against several large equipment manufacturers with respect to its products, while the research services industry is highly fragmented consisting of several hundred service providers operating in various segments of the market and a few larger companies focusing primarily on managing clinical trials. While the markets for the Company's products and services have distinct customers (often simply separate divisions in a large pharmaceutical company) and requirements, the Company believes that both markets are facing increased pressure to outsource certain facets of their research and development activities. The Company believes that the factors identified below will contribute to a continuing increase in outsourcing activities by its customers.

Drug Development Pressure

The pharmaceutical industry is under pressure to rapidly develop new drugs to treat chronic illnesses and life threatening conditions such as AIDS and Alzheimer's disease as consumers, doctors, health care providers and pharmaceutical company shareholders continue to demand quicker and more efficient drug development. Responding to this pressure, pharmaceutical companies are attempting to accelerate the drug development process, including reliance to an increasing extent on external providers of research and development services to perform testing and analysis in all phases of the process.

Emphasis on Cost Containment

Pharmaceutical companies are facing increasing pressure to develop more efficient operating strategies as a result of margin pressure from market forces, including (i) a shift toward managed care, (ii) patent expirations,
(iii) generic substitution, (iv) increased purchasing power of large buyer groups and (v) governmental initiatives designed to reduce drug prices. The Company believes that the pharmaceutical and medical device industries are responding to these pressures by downsizing internal research and development programs, favoring outsourcing as a variable-cost alternative. Further, the need for additional capacity to increase the speed of new product development, to maximize the period of marketing exclusivity and to increase economic returns, has driven the need for outsourced services.

Patent Expirations

Patents on all major pharmaceuticals continue to age and expire. According to the Pharmaceutical Research and Marketing Association, since 1984 prescriptions for generic drugs have risen from 20% to 43% of all prescriptions written. Moving generic drugs onto the market faster can result in an estimated 2 to 5 year reduction in effective patent protection for brand name drugs. Patent expirations are forcing drug companies to develop new products or modify existing products to maintain market share against generic product competition. The Company believes that the pressure to develop new products and modify (reformulate) existing products, combined with internal capacity constraints, is leading companies to outsource these activities.

Consolidation in the Pharmaceutical Industry

The pharmaceutical industry is increasingly consolidating as drug development companies continue to pursue new avenues of growth and more efficient ways of conducting business. As companies seek to combine

20

varied personnel, resources and activities, the Company believes that they will increasingly focus on ways to reduce costs and streamline operations, leading to the greater use of companies providing contract research services.

Biotechnology Industry and "Virtual" Drug Company Growth

The biotechnology industry has grown rapidly over the last 10 years and has introduced a significant number of new compounds for development. As a result, many biotechnology companies do not have the necessary in-house resources to conduct required development and testing. Furthermore, the number of pharmaceutical and medical device companies whose business strategy is to bring a product far enough along to attract a strategic partner that will manufacture and market a drug has increased. Many of these "virtual" drug development companies, having little or no internal development or support resources, must outsource a substantial portion of drug development and testing.

Need for Technical Expertise

The increasing complexity of new drugs requires high quality, innovative, solution-driven contract work through all phases of the development process from preclinical toxicology and pharmacokinetics through reformulation pharmacokinetic studies and post-market clinical drug monitoring. The Company believes that this need for specialized technical expertise will increasingly lead to outsourcing of research activities.

Need for Data Management Expertise

Regulatory agencies are increasing the volume of data required for regulatory filings, as well as requesting increased access to these data. Furthermore, the FDA is encouraging the use of computer-assisted filings in an effort to expedite the approval process; consequently, drug companies are increasingly outsourcing to firms with automated data management capabilities. Clients also are demanding access to data as it is acquired in the laboratory; and the Company has the ability to provide clients with remote access to Company computer systems while at the same time protecting client data from unauthorized access.

Globalization of the Marketplace

Foreign pharmaceutical companies, particularly in Japan and Europe, are increasingly seeking to obtain approval to market their products in the United States. Due to a lack of familiarity with the complex United States regulatory system and the difficulty in bringing their operating facilities into FDA-required GMP compliance, foreign firms are relying on independent development companies with experience in the United States to provide integrated services through all phases of product development and to assist in preparing regulatory submissions. The Company believes that domestic firms with established regulatory expertise and a broad range of integrated development services will benefit from this trend.

GROWTH STRATEGY

The Company's objective is to be the leading provider of high-quality analytical chemistry and support services to the worldwide pharmaceutical, medical device and biotechnology industries. The Company intends to leverage its facilities, technological expertise and information systems to facilitate growth and differentiate itself from its competitors. The Company has adopted a business strategy intended to accelerate growth and profitability, which consists of the following elements:

Increase Technical Staff to Expand Sales

The Company believes its investment in infrastructure and technical expertise has positioned it to significantly expand the level of services it provides to current and future clients. The Company is currently turning away opportunities to provide services because of technical personnel and capacity constraints. The Company intends to hire additional scientific personnel, allowing it to take advantage of the recent expansion of the Company's facilities and substantially increased laboratory space. The additional personnel will allow the Company to further provide services to current and future clients.

21

Implement Comprehensive Marketing and Sales Program

Due to the recent growth of the CRO industry and the highly fragmented nature of the competition, the Company believes it has been difficult for many CROs to achieve a high profile corporate identity within the marketplace. The Company's marketing strategy is to continue to build upon its reputation as a provider of high quality products and services. The Company has developed a marketing plan designed to substantially increase awareness of the products offered and services provided by the Company. The plan includes: (i) increasing the number of sales and marketing personnel, (ii) expanding the level of advertising and promotion, (iii) expanding strategic development relationships with key clients, (iv) expanding global market presence through distributors and locally focused promotion, and (v) surveying existing and potential clients to further assess needs and buying practices. The Company also intends to expand its technical services staff given that in the normal course of business of responding to client inquiries regarding the Company's products and services they have identified additional business opportunities in the services sector.

Broaden Range of Services Provided

The Company intends to expand its development capabilities by adding services that are complementary to its product development and support services. In addition to offering a broad range of integrated, value-added services that span the product life cycle from new compound characterizations to market product compliance and quality control testing, the Company plans to: (i) provide integrated formulations development services, (ii) refine current in vitro sampling methodologies, and (iii) broaden the range of services provided in connection with clinical trials. Increasing the array of services offered to clients is intended to enhance the Company's reputation for providing a turnkey approach to accurately and quickly meet product development challenges.

Expand Geographically

The Company intends to supplement its internal growth through the opening of offices in strategic locations. The Company believes that these offices will be valuable in developing and maintaining important client relationships. The Company believes that establishing a presence in certain domestic and international markets will enable it to more effectively compete for services from worldwide pharmaceutical, medical device and biotechnology customers that require a rapid turnaround. The Company intends to add facilities on the West Coast, as well as in targeted international markets. Adding facilities outside the United States will allow the Company to provide analytical services nearer to clinical sites and major pharmaceutical research centers located in international markets, without certain regulatory restrictions applicable to delivery and testing of substances in the United States. Geographic expansion may be accomplished by internal growth, acquisitions or joint ventures.

Identify and Effect Key Acquisitions

The Company believes that significant acquisition opportunities exist in the CRO industry due to its highly fragmented nature. The Company intends to focus on acquisitions of businesses that would expand its geographic presence, add to its clinical expertise in sectors in which it has significant experience and broaden its range of services. As part of its business strategy and in a continuing effort to enhance its capabilities to serve the global needs of its clients, the Company is looking at strategic acquisitions on an ongoing basis. In addition to considering the business of the candidate, the Company evaluates the ease with which an acquisition candidate may be integrated into the Company's organizational structure.

OPERATING STRATEGIES

The Company's operating strategies are derived from a strong base of expertise in analytical chemistry, obtained from not only its role as a manufacturer of state of the art instrumentation but also as a provider of contract laboratory services. This dual role strongly differentiates the Company from its competitors. The Company believes that among CROs that provide statistical, clinical, and medical services, the Company is the only one that designs and sells analytical instrumentation. Within the analytical instruments business, the

22

Company believes it is one of very few firms to maintain a separate business unit devoted to contract analytical services under the regulatory framework of GLP's and GMP's. The Company's operating strategies consist of the following elements:

Continue to Focus on Analytical Chemistry

The Company will remain focused on selling products and services related to analytical chemistry. The Company believes that this area has not been emphasized by many of the larger CROs and that they presently do not have the personnel or the scientific expertise to be successful in this field. The Company has developed and will continue to develop methodologies capable of measuring new drug substances. The Company believes that its capabilities to make highly technical measurements in blood plasma, tissue or dosage forms, for example, represents a significant competitive advantage.

Enhance the Synergy between Products and Services

The Company will continue to provide analytical chemistry solutions by selling innovative products and services. Each of these business units complements and enhances the other. For example, the Company has received certain contract service work due to the Company's expertise in selling and supporting liquid chromatography products. Conversely, the timely completion of a contracted study in the services unit has subsequently led to purchase orders from the same clients for the Company's products.

Further Emphasize High-End Assays

The Company will continue to focus on performing sophisticated analytical techniques, distinguishing the Company from entities performing commodity-like services. Clients with a need for specialized, sophisticated, instrumental techniques with extremely high sensitivity seek out highly qualified CROs such as the Company in order to maximize their likelihood of success. Many of the newer compounds being developed are pharmacologically active at much lower concentrations than before and require more sophisticated analytical techniques. Due to the expertise of the Company's staff, and the sophisticated instrumentation which it employs in its services contracts, the Company will continue to take advantage of these high-end opportunities.

Continue to Invest in State of the Art Instrumentation

The Company has historically and will continue to invest in technologies and products that are needed to support its customers' analytical chemistry needs. The Company's stature in the contract services business and its ability to distinguish itself from its competitors will be enhanced by (i) providing more capacity through purchasing automated sample analysis systems (robotics),
(ii) increasing the number of LC/MS and GC/MS systems, (iii) increasing the on-site storage space for stability samples, and (iv) adding other instrument-based techniques.

Enhance Client Relationships

The Company prides itself on its strong relationships with its clients. The Company believes that its continuous communication with clients both on the product support side and throughout the testing process has been critical to its success. The Company believes many clients view the Company's staff as a virtual extension of their own department.

Emphasize the "Annuity Effect"

The Company will continue its close working relationships with large innovator pharmaceutical companies by developing analytical methods for new drug candidates as early as possible in the drug development process. Upon acceptance of the new method by the client, the Company becomes the preferred provider of the testing services and can leverage its development expenses over the analyses of thousands of specimens generated from dozens of clinical trials and stability testing protocols. The Company thereby generates a continuing revenue stream extending over not only the drug development process but also over the

23

post-approval phase, where demand for testing services can actually increase as reformulations occur and as other clients use the Company's method for drug interaction studies.

THE COMPANY'S ROLE IN THE DRUG DEVELOPMENT PROCESS

Overview of Process

The Company has 23 years of experience in developing methodology to support the analytical chemistry requirements of the drug discovery process. Under the United States regulatory system, the development process for new pharmaceutical products can be divided into three distinct phases. The preclinical phase involves the discovery, characterization, product formulation and animal testing necessary to prepare an Investigational New Drug ("IND") exemption for submission to the FDA. The IND must be accepted by the FDA before the drug can be tested in humans. The second, or clinical phase of development follows a successful IND submission and involves the activities necessary to demonstrate the safety, tolerability, efficacy and dosage of the substance in humans, as well as the ability to produce the substance in accordance with the FDA's GMP regulations. Data from these activities are compiled in a New Drug Application ("NDA"), or for biotechnology products, a Product License Application ("PLA"), for submission to the FDA requesting approval to market the drug. The third phase follows FDA approval of the NDA, or PLA, and involves the production and continued analytical and clinical monitoring of the drug. The post-approval phase also involves the development and regulatory approval of product modifications and line extensions, including improved dosage forms.

The drug development process may be illustrated schematically as set forth below. Although the schematic is organized in a linear fashion, many of the stages of the process frequently overlap.

Process Specifics and the Company's Role

The Preclinical Phase. The development of a new pharmaceutical agent begins with the discovery or synthesis of an array of new molecules which may influence a specific target such as a membrane bound receptor or an enzyme involved in the disease under study. These libraries of molecules are screened for pharmacological activity using various in vitro and in vivo models, with the goal of selecting relatively few "leads" for further development. Once the pharmacologically active molecule is fully characterized, the agent is analyzed to confirm the integrity and quality of material produced. Development of the initial dosage forms to be used in clinical trials is completed, together with analytical chemistry protocols to determine their stability. Upon successful completion of preclinical safety and efficacy studies in animals, an IND submission is prepared and provided to the FDA for review prior to human clinical trials.

Most of the Company's products are designed for use in the preclinical phase of drug development, and the Company also provides its bioanalytical services in this phase. A good example of the role of the Company's products in the preclinical phase is the utilization of Company technology in the development of drug substances impacting the central nervous system neurotransmitters, including serotonin, dopamine, norepinephrine, and acetylcholine. These drugs are used in the treatment of such conditions as depression, Parkinson's disease, schizophrenia and Alzheimer's disease. The Company's chromatography products have been used extensively, for example, to study the influence of reuptake inhibitors on serotonin uptake and release in CNS programs at universities and a major pharmaceutical company well before 1985. The Company believes that the synergy between the Company's instrumentation products and services has been a factor in the Company being selected by major pharmaceutical companies to determine new drug candidates in thousands of Phase I-III clinical specimens.

The Clinical Phase. Following successful submission of an IND application, the sponsor is permitted to conduct Phase I human clinical trials in a limited number of healthy individuals to determine the drug's safety and tolerability. This work requires bioanalytical assays to determine the availability and metabolism of the active ingredient following administration. Expertise in method development and validation is essential for this phase, particularly with new chemical entities. Phase II clinical trials involve administering the drug to individuals who suffer from the target disease or condition to determine the drug's potential effectiveness and ideal dose. When further safety (toxicology), tolerability and an ideal dosing regimen have been established, Phase III clinical trials involving large numbers of patients are conducted to verify efficacy and safety. After the successful completion of Phase III clinical trials, the sponsor of the new drug submits an NDA, or PLA, to the FDA requesting that the product be approved for marketing.

The Company's bioanalytical work is most intensive per individual in Phase I studies where relatively few individuals are dosed. In Phase II and III the number of individuals treated accelerates rapidly, but the number of blood samples drawn per patient declines. Phase II and III studies are carried out over several years with what has become a well established analytical protocol. To maintain consistency in the analytical data, it is unusual for a sponsor to change laboratories unless there are problems in the quality or timely delivery of results. This tendency provides the "annuity effect" described previously.

One area of special interest to the Company is drug interaction studies. With increasing numbers of patients receiving multiple drug therapy, it is critical that the impact of each drug be assessed with respect to its influence on the effectiveness and toxicology of other drugs dosed simultaneously. This complicates and often extends clinical trials. Frequently, drugs from different manufacturers will be used together. A CRO such as the Company can provide services to several firms simultaneously when a potential synergy exists between their respective products. Such firms are often competitors in one therapeutic area and complementors in another area (e.g. the "cocktail" approach to HIV therapy). In such a case, a given assay technology might well be of interest to a number of clients, spreading the assay development cost. More importantly, drug interaction studies lead to new clients in a much more cost effective manner than advertising or an outside sales force.

The Post-approval Phase. Following approval, the drug manufacturer must comply with quality assurance and quality control requirements throughout production and must continue chemical analytical and stability studies of the drug in commercial production to continue to validate production processes and confirm

25

product shelf life. The drug manufacturer's raw materials must be analyzed prior to use in production, and samples from each manufactured batch must be tested prior to release of the batch for distribution to the public. The Company also provides its bioanalytical services in all areas during the post-approval phase, concentrating on bioequivalence studies of new formulations, line extensions, new disease indications and drug interaction studies.

Services

The Company provides a wide variety of services to pharmaceutical companies, medical device manufacturers, medical and research centers, academic institutions, and others. The Company's services unit has grown rapidly over the last several years. The Company began providing services primarily in response to requests from customers who had used or were using the Company's products. As the Company's reputation has grown, the Company's customers increasingly have drawn on the Company's expertise in analytical chemistry to solve complex problems which arise in the course of drug research and development. The Company's range of services now include: method development and validation; product characterization; stability testing; bioanalytical testing; diagnostic testing and in vivo sampling. The Company is poised to utilize its expertise to provide a greater volume and broader array of services. These services involve the application of the Company's expertise in analytical chemistry to a broad range of challenging and complex issues, and include the services described below.

- Method Development and Validation. The Company develops and validates methods used in a broad range of laboratory testing necessary to determine physical or chemical characteristics of compounds and finished dosage forms. Analytical methods are developed to demonstrate potency, purity, stability or physical attributes. These methods are validated to ensure that the data generated are accurate, precise, reproducible and reliable and are used throughout the drug development process and in product support testing. Of the Company's 160 employees as of September 30, 1997, more than 30 of the Company's scientists (including nine who hold Ph.D. degrees) are experienced with method development and validation.

- Product Characterization. The Company has the expertise and instruments required to identify and characterize a broad range of chemical entities. Characterization analysis identifies the chemical composition, structure and physical properties of a compound, and characterization data forms a significant portion of a regulatory application. The Company uses numerous techniques to characterize the compound, including chromatography, spectroscopy, electrochemistry and other physical chemistry techniques. Once appropriate test methods are developed and validated, and appropriate reference standards (highly pure samples) are characterized and certified, the Company can assist clients by routinely testing compounds for clinical and commercial use.

- Stability Testing. The Company provides stability testing and secure storage facilities necessary to establish and confirm product purity, potency and other shelf-life characteristics. Stability testing is required at all phases of product development, from dosage form development through commercial production, to confirm shelf life of each manufactured batch. The Company maintains a four-chamber, ICH validated controlled climate GMP facility. FDA regulations require that samples of clinical and commercial products placed in stability chambers be analyzed in a timely fashion after scheduled "pull points" occur, based on the date of manufacture.

- Bioanalytical Testing. The Company offers bioanalytical testing services to support clinical trials, analyzing plasma samples to characterize the drug's concentration and determine the rate of absorption and elimination. Bioanalytical studies of new drugs often present challenging and complex issues, with products being metabolized into multiple active and inactive forms. The Company works with its clients to develop and validate analytical methods to permit detection and measurement of the various components to trace levels. In some cases clients expect the Company to take responsibility to develop methodology and in other cases methodology is transferred from the client and refined and validated by the Company personnel. The most common technology used in such studies is liquid chromatography coupled with various detectors, including mass spectrometry as well as optical and electrochemical devices.

- Diagnostic Testing. The Company has manufactured bioanalytical chemistry products since its start in 1974. The Company produces fully automated, networkable state-of-the-art liquid chromatographs and electrochemical analyzers based on Windows(R)software. The Company has recently developed and now produces a line of diagnostic kits designed to fit its instrumentation. These kits help measure neurotransmitters and their metabolites and homocysteine, an experimental cardiovascular disease

28

indicator in plasma and urine. These measurement processes are often performed by Company personnel utilizing Company products.

- In Vivo Sampling. The Company pioneered and has commercialized miniaturized in vivo sampling methodology, which involves the continuous monitoring of chemical changes in live animals. This technology is sold as both a service and a line of products. The Company is aggressively adding new components to this line, with the goal of selling complete, automated sampling systems. Target markets include veterinary and animal research centers, pharmaceutical companies and medical research centers. The Company has received two significant Phase II SBIR grants that involve subcontracts with Purdue University and the University of Kansas for the purpose of exploiting this emerging technology.

- Formulation Development Services. In the future, the Company plans to provide integrated formulation development services, enabling the Company to take a client's compound and develop a safe and stable product with desired characteristics. The Company believes its strong academic connections to Purdue and other universities, formulation expertise and extensive analytical capabilities position the Company to provide a significant contribution to this area.

CLIENTS

Over the past five years, the Company regularly has provided services and products to all of the top 25 pharmaceutical companies in the world, as ranked by 1996 research and development spending. In fiscal 1997, the Company estimates that more than one-third of its total revenue was derived from these companies. In addition, the Company products are purchased by the vast majority of medical schools in North America, Europe and Asia. In fiscal 1997, the Company provided products and services to approximately 300 institutions, including some of the largest United States, European and Japanese drug companies. Approximately 35% of the Company's revenues are generated from customers located outside the United States.

The Company believes that a concentration of business among certain large clients is not uncommon in the CRO industry. The Company has experienced such concentration in the past and may do so again in the future. During 1996, four operating groups (Quality Control, Analytical Research and Development, Clinical Pharmacokinetics, and Drug Metabolism) of Pfizer, Inc., a major United States pharmaceutical company, in the aggregate accounted for approximately 18% of the Company's total revenues. These sales were derived from both the products and the services units of the Company. During 1997, Pfizer, Inc. accounted for approximately 21% of the Company's total revenues. Most of these sales fell under approximately 80 contracts the Company has or had with Pfizer, Inc., the largest of which totaled approximately $400,000. Although the Company strives to reduce its reliance on a limited number of major clients, there can be no assurance that the Company's business will not be dependent upon certain major clients, the loss of which could have a material adverse effect on the Company. In addition, due to the project-oriented nature of the Company's business, there can be no assurance that significant clients in any one period will continue to be significant clients in other periods. See "Risk Factors -- Dependence on Certain Industries and Clients."

SALES AND MARKETING

Marketing and sales initiatives have been created to address both market needs and economic reality. Services have grown primarily through direct, internal recommendations among major pharmaceutical manufacturers. Frequently, these customers have had prior relationships with the Company's staff and positive experiences with the Company's products and services. The Company recognizes that its growth and continued customer satisfaction are dependent upon its ability to continually improve its sales and marketing functions.

In North America, products are sold directly to the end user. The Company has approximately 20 personnel selling a range of products and an equal number providing technical and development support. All staff members are technically trained and all function in both capacities. The Company has also established a highly professional collection of catalogs, training and technical support literature, workshops, and academic publications. The Company's peer-reviewed journal, Current Separations, describes independent research in

29

technologies of interest to the Company's customers, and is distributed to 18,500 readers worldwide, many of whom are current or potential customers.

Product sales, marketing and technical support is led from the Company's main office in West Lafayette, Indiana. The Company maintains an office in New Jersey with a small sales and technical staff, enabling the Company to demonstrate its products and present technical workshops near the largest concentration of key customers. The Company also maintains sales and technical support capabilities in Massachusetts, North Carolina, Texas, Pennsylvania and Kansas.

The Company's marketing plan provides for new sales representation in California and the Midwest, stronger promotion of all product lines, enhanced workshops, training, and demonstration capabilities in the Company's new facilities. The Company's marketing and sales strategy is to be more aggressive, focus on customer needs and further strengthen communications with its markets. The Company will build on its long history of innovation and technical excellence.

BAS Technicol, Ltd., a wholly-owned subsidiary of the Company, manages most sales in Europe, and the Company maintains sales and technical support capabilities in Belgium. The Company has a network of more than 20 established distributors covering Japan, the Pacific Basin, South America, the Middle East, India, South Africa and Eastern Europe. Revenue generated from the Company's Japanese distributor, BAS Japan, accounted for approximately 12% of the Company's total revenue for fiscal 1997. Although the Company believes that it could identify a suitable replacement in the event that BAS Japan discontinues as the Company's distributor, such an event could have a material adverse effect on the Company's business, operations and financial condition. See Note 9 of Notes to Consolidated Financial Statements. All of these distributor relationships are managed from the Company's headquarters. International growth is planned through acquisitions, stronger local promotion and significantly broadening the Company's distributor network.

CONTRACTUAL ARRANGEMENTS

The Company's service contracts typically establish an estimated fee for identified services. While the Company is performing a contract, clients often adjust the scope of services to be provided by the Company in light of interim project results, at which time the amount of fees is adjusted accordingly. Generally, the Company's fee-for-service contracts are terminable by the client upon written notice of 30 days or less. The loss of a large contract or the loss of multiple contracts could adversely affect the Company's future revenue and profitability. Contracts may be terminated for a variety of reasons, including the client's decision to forego a particular study, the failure of product prototypes to satisfy safety requirements and unexpected or undesired results of product testing. See "Risk Factors -- Client Contracts Terminable Upon Notice" and "--Dependence on Certain Industries and Clients."

BACKLOG

Backlog for the Company's products consists of booked purchase orders for products which have not been shipped. The Company rarely has a backlog for its products of more than one month of sales. Many products are shipped within 24 hours of order receipt. Because the arrangements pursuant to which the Company provides its services are terminable upon written notice of 30 days or less, the Company does not calculate backlog for the services it provides and does not believe that determining such amount would provide a meaningful indicator of the future performance of its services unit.

COMPETITION

With respect to its products, the Company competes with several large equipment manufacturers, including Hewlett Packard, Waters Corporation and Perkin Elmer Corporation. Competitive factors include quality, reliability and price. The Company believes it competes favorably in its targeted markets because of its ability to combine quality products with technical assistance and services to meet customer needs.

30

With respect to its services, the Company competes primarily with in-house research, development, quality control and other support service departments of pharmaceutical and biotechnology companies, as well as university research laboratories and teaching hospitals. In addition, there are numerous full-service CRO's that compete in this industry. The largest CRO competitors offering similar research services include Covance, Inc., Pharmaceutical Product Development, Inc., Applied Analytical Industries, Inc., Phoenix International Life Sciences Inc. and MDS Health Group Ltd. CROs generally compete on the basis of previous experience, medical and scientific expertise in specific therapeutic areas, the quality of contract research, the ability to organize and manage large-scale trials on a global basis, medical database management capabilities, the ability to provide statistical and regulatory services, the ability to recruit investigators, the ability to integrate information technology with systems to improve the efficiency of contract research, an international presence with strategically located facilities, financial viability and price.

Many of the Company's competitors are much larger and have significantly greater financial resources than the Company. See "Risk Factors -- Competition."

GOVERNMENT REGULATION

The services performed by the Company are subject to various regulatory requirements designed to ensure the quality and integrity of pharmaceutical and diagnostic products, primarily under the Federal Food, Drug and Cosmetic Act and associated GLP and GMP regulations which are administered by the FDA in accordance with current industry standards. These regulations apply to all phases of manufacturing, testing and record keeping, including personnel, facilities, equipment, control of materials, processes and laboratories, packaging, labeling and distribution. Noncompliance with GLPs and GMPs by the Company in a project could result in disqualification of data collected by the Company in the project. Material violation of GLP or GMP requirements could result in additional regulatory sanctions, and in severe cases could result in a discontinuance of selected Company operations, which would have a material adverse effect on the Company's business, financial condition and results of operations.

To help assure compliance with applicable regulations, the Company has established quality assurance controls at its facilities that monitor ongoing compliance by auditing test data and regularly inspecting facilities, procedures and other GMP compliance parameters. In addition, FDA regulations and guidelines serve as a basis for the Company's standard operating procedures, where applicable. Certain of the Company's development and testing activities are subject to the Controlled Substances Act, administered by the Drug Enforcement Agency ("DEA"), which regulates strictly all narcotic and habit-forming substances. The Company maintains restricted-access facilities and heightened control procedures for projects involving such substances due to the level of security and other controls required by the DEA. In addition to FDA regulations, the Company is subject to other federal and state regulations concerning such matters as occupational safety and health and protection of the environment.

The Company's activities involve the controlled use of hazardous materials and chemicals. The Company is subject to foreign, federal, state and local laws and regulations governing the use, storage, handling and disposal of such materials and certain waste products. The risk of accidental contamination or injury from these materials cannot be completely eliminated. In the event of such an accident, the Company could be held liable for any damages that result which could have a material adverse effect on the Company's business and results of operations. See "Risk Factors -- Dependence on and Possible Adverse Effect of Government Regulation."

PRODUCT LIABILITY AND INSURANCE

The Company maintains product liability and professional errors and omissions liability insurance, providing approximately $6.0 million in coverage on a claims-made basis. In addition, in certain circumstances the Company seeks to manage its liability risk through contractual provisions with clients requiring the Company to be indemnified by the client or covered by clients' product liability insurance policies. In addition, in certain types of engagements, the Company seeks to limit contractual liability to its clients to the amount of fees received by the Company. The contractual arrangements are subject to negotiation with clients and the

31

terms and scope of such indemnification, liability limitation and insurance coverage vary from client to client and from project to project. Although most of the Company's clients are large, well-capitalized companies, the financial performance of these indemnities is not secured. Therefore,the Company bears the risk that the indemnifying party may not have the financial ability to fulfill its indemnification obligations or that liability would exceed the amount of applicable insurance. In addition, the Company could be held liable for errors and omissions in connection with the services it performs. There can be no assurance that the Company's insurance coverage will be adequate or that insurance coverage will continue to be available on terms acceptable to the Company, or that the Company can obtain indemnification arrangements or otherwise be able to limit its liability risk. See "Risk Factors -- Liability Risks Related to Products and the Provision of Services."

EMPLOYEES

At September 30, 1997, the Company had 160 full-time employees, 110 of which hold degrees, including 30 Ph.D.s. The Company believes that its relations with its employees are good. None of the Company's employees are represented by a union. The Company's performance depends on its ability to attract and retain qualified professional, scientific and technical staff. The level of competition among employers for skilled personnel is high. The Company believes that its employee benefit plans enhance employee morale, professional commitment and work productivity and provide an incentive for employees to remain with the Company. While the Company has not experienced any significant problems in attracting or retaining qualified staff, there can be no assurance that the Company will be able to avoid these problems in the future. All employees enter into confidentiality agreements intended to protect the Company's proprietary information. See "Risk Factors -- Need to Attract, Develop, Manage and Retain Professional Staff."

FACILITIES

The Company's principal executive offices are located at 2701 Kent Avenue, West Lafayette, IN 47906 constituting approximately 100,000 square feet of operational and administrative space. Purdue University, located in West Lafayette, Indiana, is exceptionally strong in pharmacy, chemistry, veterinary medicine, computer science and engineering. Its program in Analytical Chemistry is ranked among the best in the nation. The Purdue campus provides access to educational opportunities, high quality consultants, graduates and information resources. The technically trained staff that the Company requires prefers a community with the amenities of a first rate university. The Company's record for obtaining Federal and other grants has enhanced collaborative efforts with Purdue. The Company maintains offices which provide sales and technical support services in New Jersey, Pennsylvania and the United Kingdom, and employs sales and technical support service representatives in North Carolina, Texas and Belgium. The Company believes that its facilities are adequate for the Company's operations and that suitable additional space will be available when needed.

INFORMATION SYSTEMS

Although the Company's focus is on providing value-added products and services, information systems are an important component of the Company's technological leadership. The Company believes that superior information systems are essential to expanding its operations and to providing innovative services to clients. The Company's customized Windows(R)-based software is integral to many of its products.

The FDA has become increasingly sophisticated with respect to information systems and the integrity of all forms of data incorporated into regulatory submissions. Correspondingly, the Company strives to be at the forefront of nonclinical testing laboratories in validation of hardware and software systems. The Company's continuing commitment to technological innovations and meeting changing client and regulatory requirements will drive continuous improvement of its information systems technology, maintaining a competitive advantage.

LEGAL PROCEEDINGS

The Company from time to time may be involved in various claims and legal proceedings arising in the ordinary course of business. The Company does not believe that any pending claims or proceedings, individually or in the aggregate, would have a material adverse effect on the Company's financial condition or results of operations.

INCENTIVE PLAN

The Company has an incentive plan for its executive officers, the purpose of which is to strengthen the financial condition of the Company by providing an incentive bonus to its executive officers based upon the Company's pre-tax net income. If the Company's pre-tax net income, calculated before the payment of any bonuses, exceeds $500,000, each executive officer receives a bonus equal to 5% of his or her annual salary. If the Company's pre-tax net income, calculated before the payment of any bonuses, exceeds $750,000, $1 million or $1.25 million, each executive officer will receive a bonus equal to 15%, 20% or 25%, respectively, of his or her annual salary. In fiscal 1997, each executive officer received a bonus equal to 25% of his or her annual salary.

OPTION PLANS

A total of 95,000 Common Shares have been reserved for issuance under the Company's 1997 Employee Option Plan adopted October 23, 1997 and a total of 5,000 Common Shares have been reserved for issuance under the Company's 1997 Director Option Plan, of which options to purchase an aggregate of 35,000 and

37

3,000 Common Shares, respectively, have been granted at an exercise price equal to the public offering price set forth on the cover page of this Prospectus. In addition, at the date of this Prospectus options to purchase a total of 245,585 Common Shares were outstanding under the 1990 Employee Option Plan at a weighted average exercise price of $1.34 per share, and 27,086 Common Shares were outstanding under a Director Option Plan, at an exercise price of $0.66 per share. No further options may be granted under the 1990 Employee Option Plan or the 1990 Director Option Plan.

The 1990 and 1997 Employee Option Plans (the "Employee Plans") are administered by the Compensation Committee. Members of the Compensation Committee are not eligible to participate in the Employee Plans while serving on the Compensation Committee. Participants in the Employee Plans are key employees of the Company and its subsidiaries as may be selected from time to time by the Compensation Committee. Subject to the terms of the Employee Plans, the Compensation Committee is authorized to determine the number of Common Shares subject to each option granted thereunder, the time and conditions of exercise of such option and all other terms and conditions of such option.

The 1990 and 1997 Director Option Plans (the "Director Plans") are administered by a committee consisting of three or more members of the Board of Directors (the "Option Committee"). Participants in the Director Plans are directors of the Company or an affiliate of the Company who are not employed by the Company or any affiliate, as may be selected from time to time by the Option Committee.

Options granted under the Employee Plans are incentive stock options, as defined by Section 422A of the Internal Revenue Code of 1986, as amended (the "Code"). The per share exercise price of an option will be not less than 100% of the fair market value of the Common Shares on the date of the grant, except that the per share exercise price of options granted to employees who are holders of 10.0% or more of the total combined voting power of all outstanding classes of shares of the Company ("10% Shareholders") will be not less than 110% of such fair market value. In addition, for each participant who is an employee, the maximum aggregate fair market value on the date of grant of all Common Shares subject to options first exercisable in any one year may not exceed $100,000.

Options will expire on a date determined by the Compensation or Option Committee, as the case may be, provided that the options will expire not more than ten years from the date of grant (five years in the case of options issued to 10% Shareholders). Generally, all options will terminate on the date the holder ceases to be employed by, or to serve as a director of, the Company. If, however, an option holder retires with the consent of the Company or becomes permanently and totally disabled, options granted under the Option Plans will expire three months and 12 months, respectively, after the termination of employment. If an option holder's service with the Company is terminated as a result of death, the options will expire 12 months after such event. Options are not transferable other than by will or the laws of descent and distribution.

Options vest in four equal installments on the second, third, fourth and fifth anniversary of the date of grant. If the Company is a party to any merger or consolidation, the Company has the right to terminate any outstanding option upon 30 days written notice to the option holder; however, if the merger or consolidation is not consummated within 180 days from the date of such notice, all options terminated shall be deemed to have been continuously in effect. If the Company is dissolved or liquidated, the Company shall give each option holder 30 days written notice and all unexercised options shall be deemed to be terminated upon such dissolution or liquidation.

401(K) SAVINGS PLAN

The Company has a defined contribution retirement plan (the "401(k) Plan"), qualified under Sections 401(a) and 401(k) of the Code. All employees of the Company are eligible to enroll in the 401(k) Plan on the first April 1 or October 1 after completing one year of employment with the Company. The 401(k) Plan provides that the Company will contribute 2% of each eligible employee's compensation to the 401(k) Plan. In addition, each participant may contribute from 1% to 10% or none of their annual compensation. The Company may also make discretionary contributions based on a certain percentage of a participant's contributions under the 401(k) Plan, as determined by the Board of Directors. The Board of Directors approved a matching contribution of 38% beginning October 1, 1997. The Company made contributions under the 401(k) Plan totaling approximately $179,151 for the year ended September 30, 1997.

LIMITATION OF LIABILITY AND INDEMNIFICATION MATTERS

As permitted by the Indiana Business Corporation Law (the "BCL"), the Second Restated Articles of Incorporation of the Company (the "Articles") require the Company to indemnify its officers and directors from liabilities to the extent allowed by the BCL. The BCL provides that a corporation may indemnify its officers and directors, if the officer or director acted in good faith and in a manner he reasonably believed, in the case of conduct in his official capacity, was in the best interests of the Company and, in all other cases, was not opposed to the best interests of the Company, and, with respect to any criminal proceeding, the officer or director had reasonable cause to believe his conduct was lawful or no reasonable cause to believe his conduct was unlawful. The BCL further provides that the Company may advance to its officers and directors expenses incurred in connection with proceedings against them for which they may be indemnified, if the Company receives a written affirmation from such officer or director that in his good faith belief he met the standard of conduct described above and that he will repay all advanced expenses if it is ultimately determined that he did not meet that standard of conduct. Pursuant to the BCL, the Company may obtain directors' and officers' insurance. At present, the Company is not aware of any pending or threatened litigation or proceeding involving an officer, director, employee or agent of the Company in which indemnification would be required or permitted.

The Company maintains directors' and officers' liability insurance with respect to certain risks to which the Company and its directors and officers are exposed.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

Peter T. Kissinger, Thomas Hiatt, John Kraeutler and William Mulligan served on the Compensation Committee during fiscal 1997. Dr. Kissinger, the President and Chief Executive Officer of the Company, currently is a member of the Compensation Committee; however, he does not participate in decisions regarding his compensation. None of the Company's executive officers serves as a director of, or in any compensation related capacity for, companies with which members of the Compensation Committee are affiliated.

CERTAIN TRANSACTIONS

In 1991 Primus Capital Fund II, LP ("Primus") and Middlewest Ventures II, LP ("Middlewest") purchased Redeemable Preferred Shares and Convertible Preferred Shares of the Company. The Redeemable Preferred Shares carried an 8% cumulative dividend, and were redeemed in accordance with their terms for an amount equal to their purchase price in equal installments on December 31, 1995, June 30, 1996 and December 31, 1996. See Note 6 of Notes to Consolidated Financial Statements.

The Venture Funds continue to have certain rights to cause the Company to register the Common Shares owned by the Venture Funds under the Securities Act for sale to the public. See "Description of Capital Stock -- Registration Rights." Additionally, the Company has agreed to use its best efforts to cause one representative from each Venture Fund to be elected to the Company's Board of Directors as long as the respective Venture Fund owns more than 5% of the Company's outstanding Common Shares. All other covenants between the Company and the Venture Funds will be terminated in connection with the conversion of the Convertible Preferred Shares to Common Shares.

DESCRIPTION OF CAPITAL STOCK

Upon the closing of this offering, the authorized capital stock of the Company will consist of 19 million Common Shares, and one million preferred shares (the "Preferred Shares") none of which will be outstanding. As of September 30, 1997, there were 2,247,601 Common Shares issued and outstanding held of record by 63 shareholders and the Company had outstanding options to purchase a total of 272,671 Common Shares.

The following summary of certain provisions of the Common Shares and Preferred Shares does not purport to be complete and is subject to, and qualified in its entirety by, the provisions of the Articles of Incorporation, which are included as an exhibit to the Registration Statement on Form S-1 (including all schedules, exhibits and amendments thereto, the "Registration Statement"), and by the provisions of applicable law.

COMMON SHARES

Upon the completion of this offering, the Company's Articles of Incorporation will authorize the issuance of up to 19 million Common Shares. Holders of Common Shares are entitled to one vote for each Common Share held on all matters submitted to a vote of shareholders and do not have cumulative voting rights. Accordingly, holders of a majority of the Common Shares entitled to vote in any election of directors may elect all of the directors standing for election. Holders of Common Shares are entitled to receive ratably such dividends, if any, as may be declared by the Company's Board of Directors out of funds legally available therefor and subject to any preferential dividend rights of any then outstanding Preferred Shares. Upon the liquidation, dissolution or winding up of the Company, the holders of Common Shares are entitled to receive ratably the net assets of the Company available after the payment of all debts and other liabilities and subject to any preferential dividend rights of any then outstanding Preferred Shares. Holders of Common Shares have no preemptive, subscription, redemption or conversion rights. The outstanding Common Shares are, and the Shares offered by the Company in this offering will be, when issued and paid for, fully paid and nonassessable.

PREFERRED SHARES

The Board of Directors is authorized, subject to any limitations prescribed by Indiana law, to provide for the issuance of Preferred Shares in one or more series, to establish from time to time the number of shares to be included in each such series, to fix the powers, designations, preferences and rights of the shares of each wholly unissued series and any qualifications, limitations or restrictions thereon and to increase or decrease the number of shares of any such series (but not below the number of shares of such series then outstanding)

42

without any further vote or action by the shareholders. The Board of Directors may authorize the issuance of Preferred Shares with voting or conversion rights that could adversely affect the voting power or other rights of the holders of Common Shares. The issuance of Preferred Shares could have the effect of decreasing the market price of the Shares. The issuance of Preferred Shares may have the effect of delaying, deferring or preventing a change in control of the Company. The Company has no current plan to issue any Preferred Shares.

REGISTRATION RIGHTS

Upon the completion of this offering, the Venture Funds will have certain rights with respect to the registration of under the Securities Act an aggregate of 752,399 Common Shares held by them. If requested by the Venture Funds, the Company must file a registration statement under the Securities Act covering all Common Shares requested to be included by the Venture Funds within 60 days. The Venture Funds may make an unlimited number of requests for registration; provided, however, that the Company is only required to bear the expense of one registration. The Company has the right to delay any registration for up to 90 days under certain circumstances.

In addition, if the Company proposes to register any of its Common Shares under the Securities Act other than in connection with a Company employee benefit plan or a corporate reorganization, the Venture Funds may require the Company to include all or a portion of their shares in that registration, subject to certain priorities among them, although the managing underwriter of any such offering may limit the number of Common Shares to be offered by the Venture Funds.

CERTAIN PROVISIONS OF INDIANA LAW

As an Indiana corporation, the Company is governed by the provisions of the
BCL.

Voting Requirements for Certain Business Combinations. Chapter 43 of the BCL establishes a five-year period beginning with the acquisition of 10% of the voting power of the outstanding voting shares of a "resident domestic corporation" (which definition includes the Company) during which certain business transactions involving the acquiring shareholder are prohibited unless, prior to the acquisition of such interest, the board of directors approves the acquisition of such interest or the proposed business combination. After the five-year period expires, a business combination involving the acquiring shareholder may take place only upon approval by a majority of the disinterested shares, or if the other shareholders receive a formula price based on the higher of the highest price paid by the acquiring shareholder or the market value at the time of the announcement of the proposed transaction, whichever is higher. The minimum price for shares other than common shares is to be determined under criteria similar to that for common shares, except the minimum price as defined cannot be less than the highest preferential amount to which the shares are entitled in the event of any liquidation, dissolution or winding up of the corporation.

Changes of Control. Under Chapter 42 of the BCL, with certain exceptions, a person proposing to acquire or acquiring voting shares of an "issuing public corporation" (which definition includes only corporations having at least 100 shareholders, principal place of business, office or substantial assets within Indiana, and in which more than 10% of its shareholders are Indiana residents, 10% of its shares are owned by Indiana residents, or which have 10,000 or more shareholders who are Indiana residents) sufficient to entitle that person to exercise voting power within any of the ranges of one-fifth to one-third of all voting power, more than one-third but less than one-half of all voting power, or a majority or more of all voting power (a "control share acquisition") may give a notice of such fact to the corporation containing certain specified data. The acquiring person may request that the directors call a special meeting of shareholders for the purpose of considering the voting rights to be accorded the shares so acquired ("control shares"), and the control shares have voting rights only to the extent granted by a resolution approved by the shareholders. The resolution must be approved by a majority of the votes entitled to be cast by each voting group entitled to vote separately on the proposal, excluding shares held by the acquiring person and shares held by management. Control shares as to which the required notice has not been filed and any control shares not accorded full voting rights by the shareholders may be redeemed at fair market value by the corporation if it is authorized to do so by its articles

43

of incorporation or bylaws before a control share acquisition has occurred. The Company has not adopted such a provision in its Articles or Bylaws. Shareholders are entitled to dissenters rights with respect to the control share acquisition in the event that the control shares are accorded full voting rights and the acquiring person has acquired control shares with a majority of all voting power.

Other Provisions of the BCL. The BCL specifically authorizes directors, in considering the best interest of a corporation, to consider both the long- and short-term interests of the corporation, as well as the effects of any action on shareholders, employees, suppliers and customers of the corporation, and communities in which offices or other facilities of the corporation are located and any other factors the directors consider pertinent. Under the BCL, directors are not required to approve a proposed business combination or other corporate action if they determine in good faith that the action is not in the best interest of the corporation. In addition, the BCL states that directors are not required to redeem any rights under or render inapplicable a shareholder rights plan or to take or decline to take any other action solely because of the effect such action or inaction might have on a proposed change of control of the corporation or the amounts to be paid to shareholders upon such a change of control. The Delaware Supreme Court has held that defensive measures in response to a potential takeover must be "reasonable in relation to the threat posed." The BCL explicitly provides that the different or higher degree of scrutiny imposed in Delaware and certain other jurisdictions upon director actions taken in response to potential changes in control will not apply.

The BCL requires directors to discharge their duties, based on the facts then known to them, in good faith, with the care an ordinary, prudent person in a like position would exercise under similar circumstances and in a manner the director reasonably believes to be in the best interest of the corporation. A director is not liable for any action taken as a director or for failure to take any action unless the director has breached or failed to perform the duties of the director's office in compliance with the foregoing standard and the breach or failure to perform constitutes willful misconduct or recklessness.

TRANSFER AGENT AND REGISTRAR

The Transfer Agent and Registrar for the Shares is National City Bank. Its telephone number is (216) 575-2494.

SHARES ELIGIBLE FOR FUTURE SALE

Upon the closing of this offering, the Company will have outstanding an aggregate of 4,500,000 Common Shares.

All of the Company's officers and directors and certain of the Company's shareholders have agreed with the Underwriters that, for a period of 180 days after the date of this Prospectus, subject to certain exceptions, they will not directly or indirectly offer, sell, contract to sell, pledge, grant any option to purchase, establish an open "put equivalent position" within the meaning of Rule 16a-1(h) under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), or otherwise dispose of or grant any rights with respect to any Common Shares (or any securities convertible into, exchangeable for or exercisable for Common Shares), without the prior written consent of the Underwriters (the "Lock-Up Agreements"). In its sole discretion and at any time without notice, the Underwriters may release all or any portion of the Common Shares subject to the Lock-Up Agreements.

Following the expiration of the 180-day lock-up period, or earlier with the written consent of the Underwriters, 2,334,592 Common Shares will be eligible for sale by existing shareholders of the Company subject to the volume and other limitations of Rule 144, as discussed below.

In general, under Rule 144 any holder of restricted securities, as defined under Rule 144, including an affiliate of the Company, as to which at least one year has elapsed since the later of the date of acquisition of the Common Shares from the Company or an affiliate, would be entitled beginning 90 days after the date of this Prospectus, to sell within any three-month period a number of Common Shares that does not exceed the

44

greater of 1% of the then outstanding Common Shares (approximately 45,000 shares upon the completion of this offering) or the average weekly trading volume of the Common Shares on the Nasdaq National Market during the four calendar weeks preceding the date on which notice of the sale is filed with the Commission. Sales under Rule 144 are subject to certain requirements relating to manner of sale, notice and availability of current public information about the Company. However, a person (or persons whose Common Shares are aggregated) who is not deemed to have been an affiliate of the Company at any time during the 90 days immediately preceding the sale and who beneficially owned the Common Shares for at least two years since the later of the date the Common Shares were acquired from the Company or an affiliate of the Company may sell those shares under Rule 144(k) without regard to the limitations described above. The foregoing is a summary of Rule 144 and is not intended to be a complete description of it.

As of September 30, 1997, there were 272,671 Common Shares subject to outstanding options issued pursuant to the Company's Option Plans, of which approximately 236,555 Common Shares were vested as of that date. The Company intends to file a registration statement under the Securities Act to register Common Shares reserved for issuance under the Option Plans, thereby permitting the sale of those Common Shares by non-affiliates in the public market without restriction under the Securities Act. That registration statement will become effective immediately upon filing.

Subject to certain limitations on the aggregate offering price of a transaction and other conditions, Rule 701 may be relied upon with respect to the resale of securities originally purchased from the Company by its employees, directors, officers, consultants or advisers prior to the closing of this offering pursuant to written compensatory benefit plans or written contracts relating to the compensation of such persons. In addition, the Commission has indicated that Rule 701 will apply to options granted by the Company before this offering, along with the Common Shares acquired upon exercise of such options. Securities issued in reliance on Rule 701 are deemed to be Restricted Shares and, subject to the contractual limitations described above, beginning 90 days after the date of this Prospectus, may be sold by persons other than affiliates subject only to the manner of sale provisions of Rule 144 and by affiliates under Rule 144 without compliance with its one-year minimum holding period requirements.

UNDERWRITING

Subject to the terms and conditions contained in the Underwriting Agreement, each of the underwriters named below (the "Underwriters") has severally agreed to purchase, and the Company has agreed to sell to such Underwriter, the respective number of Shares set forth opposite the name of such Underwriter:

                                                               NUMBER OF

                            ----                               ---------
Roney & Co., L.L.C. ........................................
The Ohio Company............................................

                                                              ------------
     Total..................................................
                                                              ============

The Underwriting Agreement provides that the obligations of the several Underwriters to pay for and accept delivery of the Shares offered hereby are subject to approval of certain legal matters by their counsel and to certain other conditions. The Underwriters are obligated to take and pay for all Shares offered hereby (other than those covered by the over-allotment option described below) if any such shares are purchased.

The Underwriters, for whom Roney & Co., L.L.C. and The Ohio Company are acting as representatives (the "Representatives"), propose to offer part of the Shares directly to the public at the public offering price set forth in the cover page of this Prospectus and part of the shares to certain dealers at a price which represents a concession not in excess of $ per share under the public offering price. The Underwriters may allow, and such dealers may reallow, a concession not in excess of $ per share to certain other dealers. After the offering, the offering price and other selling terms may be changed. The Representatives have advised the Company that the Underwriters do not intend to confirm sales to any accounts over which they exercise discretionary authority.

The Company has granted to the Underwriters an option, exercisable for 30 days from the date of this Prospectus, to purchase up to an aggregate of 225,000 additional Shares, respectively, at the public offering price set forth on the cover page of this Prospectus minus the underwriting discounts and commissions. The Underwriters may exercise such option solely for the purpose of covering over-allotments, if any, in connection with the sale of the shares offered hereby. To the extent such option is exercised, each Underwriter will be obligated, subject to certain conditions, to purchase approximately the same percentage of such additional shares as the number of share set forth opposite such Underwriter's name in the preceding table bears to the total number of share in such table.

The Company and all of its directors and executives officers, who beneficially hold an aggregate of 2,334,592 Shares, have agreed that, for a period of 180 days following the date of this Prospectus, they will not, without the prior written consent of the Representatives, offer, sell, contract to sell, or otherwise dispose of any Shares of the Company; provided, however, that the Company may issue and sell up to 372,671 Common Shares pursuant to the Option Plans in effect on the date of this Prospectus or to non-employee Directors.

Prior to the offering, there has not been any public market for the Common Shares of the Company. Consequently, the initial public offering price for the Shares included in the offering will be determined by negotiations between the Company and the Representatives. Among the factors to be considered in determining such price are the history of and prospects for the Company's business and the industry in which it competes, an assessment of the Company's management and the present state of the Company's development, the past and present revenues and earnings of the Company, the prospects for the growth of Company's revenues and earnings, the current state of the economy in the United States and the current level of economic activity in the industry in which the Company competes and in related or comparable industries,

46

and currently prevailing conditions in the securities markets, including current market valuations of publicly traded companies that are comparable to the Company.

The Company has agreed to indemnify the Underwriters against certain liabilities, including certain liabilities under the Securities Act or to contribute to payments that the Underwriters may be required to make in respect thereof.

The Underwriters have reserved for sale, at the initial public offering price, up to 30,000 of the Shares offered hereby for employees of the Company and certain other individuals who have expressed an interest in purchasing such Shares in the offering. The number of shares available for sale to the general public will be reduced to the extent such persons purchase such reserved shares. Any reserved shares not so purchased will be offered by the Underwriters to the general public on the same basis as the other shares offered hereby.

47

LEGAL MATTERS

The validity of the Shares offered hereby will be passed upon for the Company by Ice Miller Donadio & Ryan, Indianapolis, Indiana. Certain legal matters in connection with this offering will be passed upon for the Underwriters by Honigman Miller Schwartz & Cohn.

ROBOTIC SAMPLE PREPARATION AND DISSOLUTION TESTING: Rapid, cost effective, fully automated sample preparation and dissolution tests which are typically quantified by liquid chromatography.

SAFETY: No drug is completely safe or without the potential for side effects. Before a drug may be approved for marketing, the law requires the submission of results of tests adequate to show the drug is safe under the conditions of use in the proposed labeling. Thus, "safety" is determined case by case and reflects the drug's risk v. benefit relationship.

SBIR GRANTS: Federal Small Business Innovation Research and Small Business Technology Transfer Grants. These support research in topics of interest to NASA, NIH, etc. Awards, term and degree of industry involvement vary.

SOLID PHASE EXTRACTION: An analytical separation technique in which a mixture of chemicals is stirred with a solid, usually a powder.

BIOANALYTICAL SYSTEMS, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. SIGNIFICANT ACCOUNTING POLICIES

NATURE OF BUSINESS

Bioanalytical Systems, Inc. and its subsidiaries (the "Company") manufacture scientific instruments for use in the determination of trace amounts of organic compounds in biological, environmental and industrial materials. The Company sells its equipment and software for use in industrial, governmental and academic laboratories. The Company also engages in laboratory services, consulting and research related to analytical chemistry and chemical instrumentation. The Company's customers are located in the United States and throughout the world.

PRINCIPLES OF CONSOLIDATION

The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All significant inter-company accounts and transactions have been eliminated.

CASH EQUIVALENTS

The Company considers all short-term, highly liquid investments to be cash equivalents.

FINANCIAL INSTRUMENTS

Management has estimated that the fair value of financial instruments, including cash and cash equivalents, accounts receivable, accounts payable and debt approximates the carrying values.

INVENTORIES

Inventories are stated at the lower of cost or market. Cost is determined using the last-in, first-out (LIFO) method.

GOODWILL

Goodwill represents the excess of cost of acquisitions over the fair value of net assets acquired and is amortized by the straight-line method over a twenty year period.

PROPERTY AND EQUIPMENT

Property and equipment is recorded at cost. Depreciation is computed using the straight-line method over the estimated useful lives of 10 through 40 years. Expenditures for maintenance and repairs are charged to expense as incurred.

The Financial Accounting Standards Board (FASB) issued Statement of Accounting Standards No. 121 (SFAS 121), "Accounting for Impairment of Long-Lived Assets and for Assets to be Disposed of," which the Company adopted effective October 1, 1995. SFAS 121 requires that long-lived assets and certain identifiable intangibles held and used by the Company be reviewed for possible impairment whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. Adoption of the Statement and its application during 1996 and 1997 did not have an impact on the Company's financial position or results of operations.

REVENUE RECOGNITION

Revenue from the sale of the Company's products and the related costs are recognized upon shipment of the products to customers. The Company's pharmaceutical service contracts generally have terms ranging from several months to several years. A portion of the contract fee is generally payable upon receipt of the

F-7

BIOANALYTICAL SYSTEMS, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- CONTINUED

1. SIGNIFICANT ACCOUNTING POLICIES -- CONTINUED initial samples with the balance payable in installments over the life of the contract. The Company's contracts are broken down into discrete units of deliverable services for which a fixed fee for each unit is established and revenue and related direct costs are recognized as specific contract terms are fulfilled under the percentage of completion method utilizing units of delivery.

INCOME TAXES

The Company computes its income tax provision in accordance with Statement of Financial Accounting Standards No. 109, "Accounting for Income Taxes" (SFAS 109). SFAS 109 requires recognition of deferred tax liabilities and assets for the expected future tax consequences of events that have been included in the financial statements or tax returns. Under this method, deferred tax liabilities and assets are determined based on the difference between the financial statement and tax bases of assets and liabilities. These deferred taxes are measured by applying the provisions of tax laws in effect at the balance sheet date.

ADVERTISING EXPENSE

The Company expenses advertising costs as incurred. Advertising expense was $238,612, $267,184 and $275,850 for 1995, 1996, and 1997, respectively.

NET INCOME PER COMMON SHARE

Net income per common share is computed on the basis of the weighted average number of common and common equivalent shares outstanding during each year. Common equivalent shares include options to purchase Common Shares and convertible preferred shares, which are assumed to be converted. In this computation, net income is reduced by dividends accrued on the Redeemable Preferred Shares.

Supplemental net income per share is computed by dividing supplemental net income (which includes net income plus interest expense, net of the related income tax benefit) by the weighted average number of shares that would have been outstanding after giving effect to the number of shares that were required to be sold in this public offering to repay borrowings under the Company's lines of credit and long-term debt facilities at October 1, 1996. Supplemental net income per share for 1997 was $0.20.

USE OF ESTIMATES

The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.

RECENTLY ISSUED ACCOUNTING STANDARDS

In July 1997, the FASB issued Statement No. 131 (SFAS 131), "Disclosures about Segments of an Enterprise and Related Information". Under SFAS 131, the Company will report financial and descriptive information about its operating segments. SFAS 131 is effective for fiscal years beginning after December 15, 1997. The Company plans to adopt SFAS 131 on October 1, 1998. The Company has not yet evaluated the impact of adoption of SFAS 131.

In June 1997, the FASB issued Statement of Financial Accounting Standards No. 130 (SFAS 130), "Reporting Comprehensive Income." SFAS 130 establishes standards for reporting and display of comprehensive income in the financial statements. SFAS 130 is effective for fiscal years beginning after December 15,

1. SIGNIFICANT ACCOUNTING POLICIES -- CONTINUED 1997. The Company plans to adopt SFAS 130 on October 1, 1998. The Company has not yet evaluated the impact of SFAS 130.

In February 1997, the FASB issued Statement of Financial Accounting Standards No. 128 (SFAS 128), "Earnings per Share", which replaces the presentation of primary earnings per share (EPS) with basic EPS and replaces fully diluted EPS with diluted EPS. It also requires dual presentation of basic and diluted EPS on the face of the income statement for all entities with complex capital structures and requires a reconciliation of the components of the basic EPS computation to the components of the diluted EPS computation. SFAS 128 is effective for both interim and annual periods ending after December 15, 1997. Earlier adoption is not permitted. Upon adoption, all prior-period EPS data presented will be restated. The Company does not anticipate the adoption of SFAS 128 to have a significant effect on EPS.

2. ACQUISITION

Effective April 3, 1995 the Company acquired all of the capital stock of Technicol, Limited for cash approximating $97,000 and 22,572 common shares. The acquired business was involved in the distribution of chromatography equipment and supplies to pharmaceutical firms in the United Kingdom.

The acquisition was accounted for using the purchase method of accounting and the results of operations have been included in the consolidated financial statements since the date of acquisition. The purchase price was allocated to the net assets acquired, including $240,032 to goodwill, based upon the fair market value at the date of acquisition.

On an unaudited pro forma basis, revenue, net income and net income per share for the year ended September 30, 1995, was $12,892,000, $510,000 and $0.15, respectively. This pro forma data presents the consolidated results of operations as if the acquisition had occurred on October 1, 1994, after giving effect to certain adjustments, including amortization of goodwill, increased interest expense and related income tax effects. The pro forma results have been prepared for comparative purposes only and do not purport to indicate the results of operations which would actually have occurred had the acquisition been in effect on the date indicated, or which may occur in the future.

the prime rate plus .25% (8.75% at September 30, 1997). At September 30, 1997, the collateral base for this line of credit resulted in borrowing availability of approximately $2,200,000, of which $200,000 was outstanding at September 30, 1997. The line is collateralized by inventories and accounts receivable.

The Company has a bank line of credit agreement for capital expenditures which expires March 1, 1998 and allows borrowings of the lesser of 80% of capital expenditures or $1,000,000. Interest is charged at the prime rate plus .25% (8.75% at September 30, 1997). At September 30, 1997, $315,377 was outstanding on this line. This line is collateralized by property and equipment, inventories and accounts receivable.

During 1996, the Company entered into a credit facility for up to $5,000,000 for the purchase and renovation of an adjacent building (the "Construction loan"). At maturity (January 31, 1998), the loan may be converted to a five year term loan based upon a 20 year amortization funding on a conventional commercial mortgage basis or with fixed principal payments plus interest. Interest is charged at the prime rate plus .25% (8.75% at September 30, 1997). This credit facility is collateralized by property and equipment. The agreement contains certain covenants, which among other things require the Company to maintain minimum levels of tangible net worth and debt service coverage.

Long-term debt at September 30 consisted of the following:

]Net operating loss carryforwards were generated by a subsidiary of the Company prior to its acquisition by the Company and the carryforwards are restricted to use by that subsidiary. These carryforwards expire through the year 2004.

In fiscal 1996 and 1997, the Company's foreign operations generated losses before income taxes of $200,145 and $245,800, respectively.

Payments made in 1995, 1996 and 1997 for federal and state income taxes amounted to $163,950, $160,000 and $140,000, respectively.

6. PREFERRED SHARES AND SHAREHOLDERS' EQUITY

PREFERRED SHARES

On February 27, 1991 the Board of Directors approved the issuance of up to 1,000,000 shares of Preferred Shares. The Board of Directors designated 105,000 shares as Redeemable Preferred Shares ($10.00 stated value) and designated 250,000 shares as Convertible Preferred Shares ($8.00 stated value).

The Redeemable Preferred Shares have preference over all other outstanding classes of capital shares of the Company with respect to payment of dividends. Holders of Redeemable Preferred Shares are entitled to receive, when and as declared by the Board of Directors, cumulative preferential cash dividends at the rate of $.80 per share per annum payable quarterly in arrears, however, they do not participate with respect to other dividends declared by the Company. Although such dividends have not been declared, the Company has recorded the dividends as a charge to Retained Earnings and an increase to Redeemable Preferred Shares. The Redeemable Preferred Shares were redeemed by the Company in three equal installments on December 31, 1995, June 30, 1996 and December 1, 1996 at $10.00 per share plus accrued unpaid dividends.

The holders of the Convertible Preferred Shares have the right at any time to convert those shares, in whole or in part and without additional consideration, into fully paid Common Shares. The conversion rate is one Common Shares for each Convertible Preferred Share at September 30, 1997 (4.514 Common Shares for each Convertible Preferred Share after the share split described in Note 10). Holders of Convertible Preferred Shares are entitled to one vote per share on any matter submitted to a vote of the holders of Common Shares. No cash dividends may be declared and paid with respect to the Common Shares unless equivalent dividends are also declared and paid with respect to the Convertible Preferred Shares. These shares are redeemable, at the option of the holders, in three equal installments on December 31, 1995, June 30, 1996 and December 31, 1996, at a redemption price of $8.00 per share plus any accrued unpaid dividends. No redemption requests were made by the holders during 1997.

Alternatively, the holders of the Convertible Preferred Shares may require the Company to purchase all or any portion of the Convertible Preferred Shares and any Common Shares obtained through the conversion of the Convertible Preferred Shares at a price equal to the greater of the amount such shares are entitled to receive upon liquidation of the Company or fair market value. The fair market value could exceed the $8 optional redemption price. As of September 30, 1997, the holders of the Convertible Preferred Shares have executed agreements to convert these shares into Common Shares concurrent with the Company's initial public offering.

The Company must maintain certain restrictive covenants in accordance with the preferred stock agreement, including net worth and indebtedness requirements, restrictions on the declaration of dividends, redemption of Common Shares, issuance of Preferred and Common Shares and capital expenditure levels.

6. PREFERRED SHARES AND SHAREHOLDERS' EQUITY -- CONTINUED STOCK OPTION PLANS

During 1990, the Company established an Employee Incentive Stock Option Plan whereby options to purchase shares of the Company's Common Shares at fair market value can be granted to employees of the Company. Options granted become exercisable in four equal installments beginning two years after the date of the grant. The plan terminates in the year 2000.

During fiscal 1989, the Company established an Outside Director Stock Option Plan whereby options to purchase shares of the Company's Common Shares at fair market value can be granted to outside directors. Options granted become exercisable in four equal installments beginning two years after the date of grant. The plan terminates in 1999.

The Company has adopted new stock option plans in connection with its initial public offering and accordingly does not plan to grant any more options pursuant to the plans discussed above.

The Company applies the provisions of Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to Employees" (APB 25) and related Interpretations in accounting for its employee stock options because the alternative fair value accounting provided for under SFAS 123, "Accounting for Stock-Based Compensation," requires use of opinion valuation models that were not developed for use in valuing employee stock options. Under APB 25, because the exercise price of the Company's employee stock options equals the estimated market price of the underlying shares on the date of grant, no compensation expense is recognized.

A summary of the Company's stock option activity, and related information for the years ended September 30 follows:

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

The Indiana Business Corporation Law ("BCL"), the provisions of which govern the Registrant, empowers an Indiana corporation to indemnify present and former directors, officers, employees, or agents or any person who may have served at the request of the corporation as a director, officer, employee, or agent of another corporation ("Eligible Persons") against liability incurred in any proceeding, civil or criminal, in which the Eligible Person is made a party by reason of being or having been in any such capacity, or arising out of his status as such, if the individual acted in good faith and reasonable believed that (a) the individual was acting in the best interests of the corporation, or
(b) if the challenged action was taken other than in the individual's official capacity as an officer, director, employee or agent, the individual's conduct was at least not opposed to the corporation's best interests, or (c) if in a criminal proceeding, either the individual had reasonable cause to believe his conduct was lawful or no reasonable cause to believe his conduct was unlawful.

The BCL further empowers a corporation to pay or reimburse the reasonable expenses incurred by an Eligible Person in connection with the defense of any such claim, including counsel fees; and, unless limited by its articles of incorporation, the corporation is required to indemnify an Eligible Person against reasonable expenses if he is wholly successful in any such proceeding, on the merits or otherwise. Under certain circumstances, a corporation may pay or reimburse an Eligible Person for reasonable expenses prior to final disposition of the matter. Unless a corporation's articles of incorporation otherwise provide, an Eligible Person may apply for indemnification to a court which may order indemnification upon a determination that the Eligible Person is entitled to mandatory indemnification for reasonable expenses or that the Eligible Person is fairly and reasonably entitled to indemnification in view of all the relevant circumstances without regard to whether his actions satisfied the appropriate standard of conduct.

Before a corporation may indemnify any Eligible Person against liability or reasonable expenses under the BCL, a quorum consisting of directors who are not parties to the proceeding must (1) determine that indemnification is permissible in the specific circumstances because the Eligible Person met the requisite standard of conduct, (2) authorize the corporation to indemnify the Eligible Person and (3) if appropriate, evaluate the reasonableness of expenses for which indemnification is sought. If it is not possible to obtain a quorum of uninvolved directors, the foregoing action may be taken by a committee of two or more directors

II-1


who are not parties to the proceeding, special legal counsel selected by the Board or such a committee, or by the shareholders of the corporation.

In addition to the foregoing, the BCL states that the indemnification it provides shall not be deemed exclusive of any other rights to which those indemnified may be entitled under any provision of the articles of incorporation or bylaws, resolution of the board of directors or shareholders, or any other authorization adopted after notice by a majority vote of all the voting shares then issued and outstanding. The BCL also empowers an Indiana corporation to purchase and maintain insurance on behalf of any Eligible Person against any liability asserted against or incurred by him in any capacity as such, or arising out of his status as such, whether or not the corporation would have had the power to indemnify him against such liability.

Reference is made to Article V of the Amended and Restated Articles of Incorporation of the Registrant concerning indemnification of directors, officers, employees and agents.

The Registrant has obtained directors' and officers' liability insurance, the effect of which is to indemnify the directors and officers of the corporation and its subsidiaries against certain losses caused by errors, misleading statements, wrongful acts, omissions, neglect or breach of duty by them or any matter claimed against them in their capacities as directors and officers.

ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES.

The Registrant has issued the following securities during the three year period ended September 24, 1997:

1. An aggregate of 142,560 Common Shares were issued to five key employees at various times upon the exercise of options granted pursuant to the Registrant's 1990 Employee Stock Option Plan for consideration equal to the fair market value of the shares purchased on the date of the option grant. The issuance of these Common Shares was exempt from registration under the Securities Act by reason of Rule 701 of the Commission and
Section 4(2) thereof.

2. An aggregate of 22,572 Common Shares were issued on April 3, 1995, to a single individual in connection with and as partial consideration for the acquisition by the Registrant of all of the outstanding shares of Technicol Ltd. The issuance of these Common Shares was exempt from registration under the Securities Act by reason of Section 4(2) thereof.

The share data set forth above has been adjusted for the 4.514 for 1 share split described in the Prospectus.

ITEM 16. EXHIBITS AND FINANCIAL STATEMENT SCHEDULES.

(a) Exhibits:

The list of exhibits is incorporated herein by reference to the Index to Exhibits.

(b) Financial Statement Schedules:

No schedules have been provided because the required information is not applicable.

ITEM 17. UNDERTAKINGS.

The undersigned Registrant hereby undertakes to provide to the Underwriters at the closing specified in the Underwriting Agreement certificates in such denominations and registered in such names as required by the Underwriters to permit prompt delivery to each purchaser.

Insofar as indemnification by the Registrant for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification for such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the

II-2


successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

The undersigned Registrant hereby undertakes that:

(1) For purposes of determining any liabilities under the Securities Act of 1933, the information omitted from the form of prospectus filed as part of this Registration Statement in reliance upon Rule 430A and contained in the form of prospectus to be filed by the Registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part of this Registration Statement as of the time it was declared effective.

(2) For the purpose of determining any liability under the Securities Act of 1933, each post-effective amendment that contains a form of prospectus shall be deemed to be a new Registration Statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

Attention: William C. Mulligan

Attention: Thomas A. Hiatt

Dear Bill and Tom:

As you are aware, Bioanalytical Systems, Inc. (the "Company") intends to file a registration statement on Form S-1 for the purpose of registering an aggregate of 1.725 million shares of its Common Shares for sale to the public (the "Offering") through underwriters led by Roney & Co. L.L.C. and The Ohio Company (the "Underwriters"). The Common Shares being registered include Common Shares subject to an over-allotment option to be granted to the Underwriters. It is anticipated that the registration statement will be filed with the Securities and Exchange Commission on or about September 26, 1997, and that the Offering will be made on or about November 25, 1997. I have enclosed a draft of the registration statement and schedules showing the pro forma share capitalization of the Company prior to and after giving effect to the Offering. It is anticipated that the public offering price of the Common Shares will be between $9 and $11 per share.

This purpose of this letter is to confirm our agreement that:

1. Effective immediately prior to the time of the closing of the underwriting agreement to be entered into between the Company and the Underwriters with respect to the Offering (the "Underwriting Agreement") and without the necessity of any further action on your part or on the part of the Company (other that those actions required to deliver to you the certificates representing the Common Shares to which you will be entitled as a result of the conversion of the Convertible Preferred Shares and the split of the Common Shares contemplated in connection with the Offering):

(a) All of the Convertible Preferred Shares of the Company held by each of Primus Capital Fund II Limited Partnership ("Primus") and Middlewest Ventures II, L.P. ("Middlewest"), aggregating 104,167 and 62,500 shares, respectively will be converted into Common Shares in accordance with the terms set forth in Section


2.3(c) of the Articles of Incorporation of the Company, as amended (the "Preferred Share Terms"), and you as holders of Convertible Preferred Shares shall not have any rights under the Preferred Share Terms with respect to the transactions contemplated by the Underwriting Agreement. Simultaneously with your execution of this letter, you will deliver to the Company: (i) the certificates representing the Convertible Preferred Shares, (ii) written notice of conversion and (iii) a proper assignment of the certificates to the Company, as contemplated by Paragraph 5 of the Preferred Share Terms, to be held by the Company in escrow pending the satisfaction of the conditions to the conversion of the shares described herein or returned to you if those conditions are not met. We hereby confirm to you that, based upon the current share capitalization of the Company, each outstanding Convertible Preferred Share is convertible into one Common Share of the Company, based upon the Preferred Share Terms.

(b) The Share Purchase Agreement between Primus, Middlewest and the Company dated as of March 15, 1991, shall be terminated and of no further force or effect. In consideration of your agreement to terminate the Share Purchase Agreement, the Company hereby grants to you the registration rights set forth on Exhibit A attached hereto (the "Registration Rights Agreement"). You agree, however, that you will not exercise your rights under Section 1 of the Registration Rights Agreement at any time prior to the expiration of the period set forth in the lock-up agreement required pursuant to the Underwriting Agreement and that you will not exercise your rights under Section 2 of the Registration Rights Agreement with respect to the Offering.

(c) The Shareholders Agreement between you and the "Management Shareholders" of the Company named therein, dated as of March 15, 1991, shall be terminated and of no further force or effect. The Company agrees that, for so long as either of you hold more than 5% of the outstanding Common Shares of the Company, it will use its best efforts to cause one person designated by that shareholder to be nominated for election to the Board of Directors of the Company upon the expiration of the term of office of the directorships now held by you or any successive term. Consistent with the Company's past practice, service on the Board would not entail compensation beyond out of pocket expenses.

2. You will vote all of the Convertible Preferred Shares held by you in favor of the approval of an amendment to the Articles of Incorporation of the Company that, among other things, will (a) delete the current provisions of Section 2.3(c) thereof, and (b) increase the number of authorized Preferred Shares of the Company to 1,000,000 shares (the "Amended Articles of Incorporation"). To that end, you hereby appoint Peter T. Kissinger and Ronald E. Shoup, and either of them, with power of substitution, as your proxy and agent with full power to attend any meeting of shareholders of the Company and to vote on your behalf all of the Convertible Preferred Shares outstanding in your names in favor of the approval of the Amended Articles of Incorporation as described herein (or to execute a consent to shareholder action in lieu of a meeting), and this proxy

- 2 -

shall be deemed to be coupled with an interest and shall not be subject to revocation by you without the consent of the Company.

3. You agree to execute the lock-up agreement as required pursuant to the Underwriting Agreement.

In the event that the Offering is not made on or before December 31, 1997, then your agreements set forth in paragraph 1 above shall terminate at the close of business on that date. The Company agrees that the Amended Articles of Incorporation described in paragraph 2 above shall not be filed with the Secretary of State of Indiana and will not become effective until immediately prior to the effective time of the closing of the Underwriting Agreement.

If this letter correctly sets forth the terms of our agreements, I would appreciate it if you would sign and return the copy provided for that purpose, and the documents described in paragraph 1(a) above (forms of which are provided herewith). Thank you for your cooperation in this matter.

Very truly yours,

Bioanalytical Systems, Inc.

EXHIBIT A

Registration of Common Shares

1. Required Registration. At any time and from time to time, upon the receipt by the Company from Primus or Middewest (collectively, the "Investors") of a written request for the registration of all or any portion of the Common Shares owned by such Investor, the Company shall prepare and file within 60 days of receipt of such request a registration statement under the Securities Act of 1933 (the "1933 Act") covering the Common Shares which are subject to such request and shall use its best efforts to cause such registration statement to become effective within 120 days of receipt of such request. The Investors shall be entitled to an unlimited number of registrations under this Section 1; provided, however, that the Company shall not be required to bear the expense of more than one such registration for all the Investors and the Investor making the request shall bear the expense of any additional registrations. In the event that an Investor determines for any reason not to proceed with a registration of Common Shares requested pursuant to this Section 1 at any time before the registration statement has been declared effective by the Securities and Exchange Commission ("SEC"), and such registration statement, if theretofore filed with the SEC, is withdrawn with respect to the Common Shares covered thereby, and such Investor agrees to bear its own expenses incurred in connection therewith and to reimburse the Company for the expenses incurred by it attributable to the registration of such Common Shares, then the Investors shall not be deemed to have exercised their right to require the Company to register Common Shares pursuant to this Section 1 at the expense of the Company. The Company shall not effect any registration of its securities (other than on Forms S-4 or S-8, or any successor or similar form) from the date of a request to register Common Shares pursuant to this Section 1 until the earlier of (i) 90 days after the date on which all securities covered by such registration statement have been sold or (ii) 180 days after the effective date of such registration statement.

2. Incidental Registration. Each time the Company shall determine to proceed with the preparation and filing of a registration statement under the 1933 Act in connection with the proposed offer and sale for money of any of its securities by the Company or any of its security holders (other than on Forms S-4 or S-8, or any successor or similar form), the Company will give written notice of its determination to the Investors. Upon the written request of an Investor given to the Company within 20 days after the mailing of any such notice by the Company as provided in this Section 2, the Company shall, subject to Sections 5 and 9 hereof, cause all such Common Shares which such Investor has requested to be registered to be included in such registration statement. Neither the delivery of a notice under this Section 2 nor a request by an Investor under this Section 2 shall, in any way, obligate the Company to file any registration statement and notwithstanding the filing of a registration statement, the Company may, at any time before the effective date thereof, elect to terminate the entire registration process without any further obligation to the Investors.

3. Short Form Registration. In addition to the registration rights provided in Sections 1 and 2 hereof, if the Company qualifies for the use of Form S-3 or any similar short form registration then in force, the Company shall, at its expense, register Common Shares on behalf of the Investors at the request of an Investor from time to time on such form.


4. Limitations. Notwithstanding the provisions of Sections l and 3 hereof, (i) the Company shall have the right to delay or suspend the preparation and filing of a registration statement for up to 90 days if in the reasonable judgment of a majority of the Board of Directors of the Company such preparation or filing would harm or hinder in any material fashion the ability of the Company to conduct its affairs or would have a material adverse effect on the business, properties or financial condition of the Company, provided, that the Company shall use its best efforts to cause any such registration statement to become effective within 150 days of receipt of an Investor's request therefor; and (ii) if, prior to an Investor's request for registration, the Company has given notice under Section 2 hereof that it intends to prepare and file a registration statement ("Section 2 Registration Statement"), then the Company shall have the right to delay or suspend the filing of the registration statement requested by an Investor, provided, that the Company shall use its best efforts to cause any such registration statement requested by an Investor to become effective within 90 days after the date on which all securities covered by the Section 2 Registration Statement have been sold.

5. Proration. If Common Shares, including any Common Shares of the Company to be issued and sold by it, are to be included under Sections 1, 2 or 3 above in a registration statement which pertains to one or more underwritten public offerings and the managing underwriters advise the Company in writing that in their opinion the number of Common Shares requested to be included exceeds the number of Common Shares which can be sold in such offering, the Company will include in such registration (i) first, such Common Shares as to which demand registration rights have been exercised under Section 1 or 3, as the case may be (the "Demand Shares"), on a pro rata basis among the holders of Demand Shares based on the number of Common Shares with respect to which demand is made; (ii) second, the Common Shares which the Company proposes to issue and sell; and (iii) third, the number of Common Shares requested by the Investors (to the extent their request was not pursuant to Section 1 or 3) to be included which in the opinion of such underwriters can be sold (the "Secondary Shares"), on a pro rata basis among holders of such Secondary Shares according to the relation the number of Common Shares owned by any such holder bears to the total number of Common Shares owned by all such holders (exclusive of Demand Shares in each case).

6. Registration Procedures. If and whenever the Company is required by the provisions of Sections 1, 2 or 3 to effect the registration of Common Shares under the 1933 Act, the Company will:

(a) prepare and file with the SEC, within 60 days of receipt of an Investor's request thereof or, a registration statement with respect to such securities, and use its best efforts to cause such registration statement to become effective within 120 days of receipt of such request and remain effective for such period as may be reasonably necessary to effect the sale of such securities, not to exceed six months;

(b) prepare and file with the SEC such amendments to such registration statement and supplements to the prospectus contained therein as may be necessary to keep such registration statement effective until the earlier of (i) the date on which all securities covered by such registration statement have been sold and (ii) 180 days after the effective date of such registration statement;


(c) use its best efforts to register or qualify the Common Shares for sale under such other securities or blue sky laws of such jurisdictions as the Investors may reasonably request and do any and all other acts and things which may be reasonably necessary or desirable to enable the Investors to consummate the disposition of the Common Shares in such jurisdictions; provided, however, that the Company shall not be required to qualify to do business or to file a general consent to service of process in any such jurisdictions;

(d) furnish to the Investors and to the underwriters of the securities being registered a reasonable number of copies of the registration statement, preliminary prospectus, final prospectus, and such other documents as the Investors or underwriters may reasonably request in order to facilitate the public offering of such securities;

(e) notify the participating Investors, promptly after it shall receive notice thereof, of the time when such registration statement has become effective or a supplement to any prospectus forming a part of such registration statement has been filed;

(f) notify the Investors promptly of any request by the SEC for the amending or supplementing of such registration statement or prospectus or for additional information;

(g) prepare and file with the SEC, promptly upon the request of the Investors, any amendments or supplements to such registration statement or prospectus which, in the opinion of counsel for the Investors (and concurred in by counsel for the Company), is required under the 1933 Act or the rules and regulations thereunder in connection with the distribution of the Common Shares by the Investors;

(h) prepare and promptly file with the SEC, and promptly notify the Investors of the filing of, any amendment or supplement to such registration statement or prospectus as may be necessary to correct any statements or omissions if, at the time when a prospectus relating to such securities is required to be delivered under the 1933 Act, any event shall have occurred as the result of which any such prospectus or any other prospectus as then in effect would include an untrue statement of a material fact or omit to state any material fact necessary to make the statement therein, in the light of the circumstances in which they were made, not misleading;

(i) advise the Investors, promptly after it shall receive notice or obtain knowledge thereof, of the issuance of any stop order by the SEC suspending the effectiveness of such registration statement or the initiation or threatening of any proceeding for that purpose and promptly use its best efforts to prevent the issuance of any stop order or to obtain its withdrawal if such stop order should be issued;

(j) at least three days prior to the filing of any amendment or supplement to such registration statement or prospectus, furnish copies thereof to the Investors and


refrain from filing any such amendment or supplement to which the Investors shall have reasonably objected on the grounds that such amendment or supplement does not comply in all material respects with the requirements of the 1933 Act or the rules and regulations thereunder, unless in the opinion of counsel for the Company the filing of such amendment or supplement is reasonably necessary to protect the Company from any liabilities under any applicable federal or state law and such filing will not violate applicable law; and

(k) at the request of the Investors, furnish on the date or dates provided for in the underwriting agreement: (i) an opinion of counsel addressed to the Investor's underwriters, if any, opining as to such matters as may be reasonably agreed to by such underwriters and the Company; and (ii) a letter or letters from the independent certified public accountants of the Company, addressed to the underwriters, if any, and to the Investors, covering such matters as such underwriters and the Investors reasonably request, in which letters such accountants shall state (without limiting the generality of the foregoing) that they are independent certified public accountants within the meaning of the 1933 Act and that in the opinion of such accountants the financial statements and other financial data of the Company included in the registration statement or any amendment or supplement thereto comply in all material respects with the applicable accounting requirements of the 1933 Act.

7. Expenses. With respect to the registrations requested pursuant to Section 1 hereof which are to be at the expense of the Company, and with respect to each inclusion of Common Shares in a registration statement pursuant to Section 2 hereof and with respect to all registrations requested pursuant to Section 3 hereof, the Company shall bear the following fees, costs, and expenses: all registration, filing, and stock exchange fees, printing expenses, fees and disbursements of counsel and accountants for the Company, fees and disbursements of counsel for the underwriter or underwriters of such securities retained by the Company, and all legal fees and disbursements and other expenses of complying with state securities or blue sky laws of any jurisdictions in which the securities to be offered are to be registered or qualified. Fees and disbursements of counsel and accountants for the Investors and for any counsel for underwriters retained solely by the Investors, underwriting discounts and commissions and transfer taxes for the Investors, and any other expenses incurred by the Investors not expressly included above shall be borne by the Investors.

8. Indemnification

(a) By the Company. The Company shall indemnify and hold harmless each Investor and any underwriter (as defined in the 1933 Act) for such Investor and each person, if any, who controls such Investor or such underwriter within the meaning of the 1933 Act, from and against any and all loss, damage, liability or claim to which such Investor or any such underwriter or controlling person becomes subject under the 1933 Act or otherwise, and to reimburse them, from time to time upon request, for any legal or other costs or expenses reasonably incurred by them in connection with investigating any claims or defending any actions, insofar as such losses, damages, liabilities, costs or expenses are caused by any untrue statement or alleged untrue statement of any


material fact contained in such registration statement, any prospectus contained therein or any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances in which they were made, not misleading; provided, however, that the Company will not be liable in any such case to the extent that any such loss, damage, liability, cost or expense arises out of or is based upon (i) an untrue statement or alleged untrue statement or omission or alleged omission (other than a statement or omission about the Company) made in conformity with information furnished by the Investors in writing specifically for use in the preparation of a registration statement or (ii) an untrue or alleged untrue statement or omission or alleged omission (other than a statement or omission about the Company) made in any preliminary prospectus made in conformity with information furnished by the Investors where the prospectus contained in the registration statement in the form filed by the Company with the SEC pursuant to Rule 424 under the 1933 Act shall have corrected such statement or omission and a copy of such prospectus shall, through no fault of the Company, not have been sent or given to the person bringing the claim at or prior to the confirmation of such sale to him.

(b) By the Investors. Each Investor shall indemnify and hold harmless the Company, the other Investor, any underwriter and each person, if any, who controls the Company, the other Investor or such underwriter, from and against any and all loss, damage, liability or claim, to which the Company or such other Investor or any controlling person and/or any underwriter becomes subject under the 1933 Act or otherwise and to reimburse them, from time to time upon request, for any legal or other costs or expenses reasonably incurred by them in connection with investigating any claims or defending any actions, insofar as such losses, damages, liabilities, costs, or expenses are caused by any untrue or alleged untrue statement of any material fact contained in such registration statement, any prospectus contained therein, or any amendment or supplement thereto, or arise out of or are based upon the omission or the alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances in which they were made, not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was so made in reliance upon and in strict conformity with written information furnished by such Investor specifically for use in the preparation thereof.

(c) Notice. Promptly after receipt by an indemnified party pursuant to the provisions of paragraph (a) or (b) of this
Section 8 of notice of the commencement of any action involving the subject matter of the foregoing indemnity provision, such indemnified party will, if a claim thereof is to be made against the indemnifying party pursuant to the provisions of said paragraph (a) or (b), promptly notify the indemnifying party in writing of the commencement thereof; but the omission to so notify the indemnifying party will not relieve it from any liability which it may have to any indemnified party otherwise than hereunder. In case such action is brought against any indemnified


party and it notifies the indemnifying party of the commencement thereof, the indemnifying party shall have the right to participate in, and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party; provided, however, if the defendants in any action include both the indemnified party and the indemnifying party and there is a conflict of interest which would prevent counsel for the indemnifying party from also representing the indemnified party, the indemnified party or parties shall have the right to elect separate counsel to participate in the defense of such action on behalf of such indemnified party or parties. After notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party will not be liable to such indemnified party pursuant to the provisions of said paragraph (a) or (b) for any legal or other expense subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation, unless (i) the indemnified party shall have employed counsel in accordance with the proviso of the preceding sentence, (ii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after the notice of the commencement of the action, or (iii) the indemnifying party has authorized the employment of counsel for the indemnified party at the expense of the indemnifying party.

(d) Contribution. If for any reason the indemnification provided for paragraphs (a) and (b) is unavailable to an indemnified party or insufficient to hold it harmless as contemplated by such paragraphs, then the indemnifying party shall contribute to the amount paid or payable by the indemnified party as a result of such loss, claim, damage or liability in such proportion as is appropriate to reflect not only the relative benefits received by the indemnified party and the indemnifying party, but also the relative fault of the indemnified party and the indemnifying party, as well as any other relevant equitable considerations; provided, however, that, in any such case, (i) no Investor will be required to contribute any amount in excess of the purchase price of all such Common Shares sold by such Investor pursuant to such registration statement, and (ii) no Investor guilty of a fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933 Act) will be entitled to contribution from any Investor who was not guilty of such fraudulent misrepresentation.

Promptly after receipt by an Investor of notice of the commencement of any action, suit or proceeding in connection with a public offering of Common Shares, such holder will, if a claim for contribution in respect thereof is able to be made against another party, notify the contributing party of the commencement thereof. The omission so to notify the contributing party will not relieve it from any liability which it may have to any other party other than for contribution under the Act. In case any such action, suit or proceeding is brought against any party, and such party notifies a contributing party of the commencement thereof, the contributing party will be entitled to participate therein with the notifying party and any other contributing party similarly notified.


9. Limitation of Market Activity. In connection with any registration of Common Shares pursuant to Sections 1, 2 or 3 hereof, each Investor, in consideration of such grant, will agree in writing prior to the date on which the registration statement becomes effective not to offer or sell any Common Shares for a period of up to 120 days following the date upon which such registration statement becomes effective under the 1933 Act if the managing underwriter so requests.

10. Transfer of Registration Rights. The registration rights and related obligations provided herein may be transferred with the securities to which they relate; provided, however, that (i) the Company shall be given written notice by the transferor thereof at the time of such transfer stating the name and address of the transferee and identifying the securities with regard to which such rights are being transferred, and (ii) the transferee shall agree in writing to assume the obligations of the transferor hereunder.

11. Investors to Provide Information. In the event the Investors request a registration of Common Shares, the Investors shall provide all such information and materials and shall take all such actions as may be reasonably required in order to permit the Company to comply with all applicable requirements of the SEC and to obtain any desired acceleration of the effective date of such registration statement. Specifically, the Company may require the Investors to furnish the Company with such information regarding the Investors and the distribution of its securities as the Company may from time to time reasonably request in writing and as shall be required by law or the SEC.

12. Rule 144 Reporting. With a view to making available the benefits of certain rules and regulations of the SEC which may permit the sale of the Common Shares to the public without registration, the Company agrees to:

(a) Make and keep public information available, as those terms are understood and defined in Rule 144 under the 1933 Act, at all times from and after 90 days following the effective date of the first registration under the 1933 Act filed by the Company for an offering of its securities to the general public;

(b) Use its best efforts to file with the SEC in a timely manner all reports and other documents required of the Company under the 1933 Act and the Securities Exchange Act of 1934 (the "1934 Act");

(c) So long as an Investor owns any Common Shares, furnish to the Investor forthwith upon request a written statement by the Company as to its compliance with the reporting requirements of Rule 144 and of the 1933 Act and the 1934 Act, a copy of the most recent annual or quarterly report of the Company, and such other reports and documents so filed as an Investor may reasonably request in availing itself of any rule or regulation of the SEC allowing an Investor to sell any such securities without registration.

13. Definition of Common Shares. For the purposes of this Exhibit

A, the term "Common Shares" shall mean the Common Shares of the Company.

EXHIBIT 10.26

BIOANALYTICAL SYSTEMS, INC.

1997 EMPLOYEE INCENTIVE STOCK OPTION PLAN

ADOPTED OCTOBER 23,1997

1. PURPOSE. This 1997 Employee Incentive Stock Option Plan (hereinafter referred to as the "Plan") is intended to be an incentive to, and to encourage share ownership by, key employees of Bioanalytical Systems, Inc. and its subsidiaries (hereinafter collectively referred to as the "Employer") in the manner contemplated by Section 422 of the Internal Revenue Code of 1986, as amended ("Code"), in order to provide such employees with a more direct and proprietary interest in the welfare and success of the Employer and to insure their continuation as employees of the Employer.

2. ADMINISTRATION. The Plan shall be administered by an Incentive Stock Option Committee (hereinafter referred to as the "Committee") consisting of three (3) or more members of the Board of Directors of Bioanalytical Systems, Inc. (the "Company") who are appointed from time to time by the Board of Directors of the Company. The Board of Directors of the Company may from time to time remove members from, or add members to, the Committee. Vacancies on the Committee, howsoever caused, shall be filled by the Board of Directors of the Company. The Committee shall have the power to interpret and construe the provisions of the Plan or any option granted under it, and such interpretation or construction shall be final and binding. The Committee may prescribe, amend and rescind rules and regulations relative to the Plan or its construction or interpretation. A majority of the Committee shall constitute a quorum. All determinations of the Committee shall be made by not less than a majority of its members. No member of the Committee shall be liable for any action or determination made in good faith.

3. ELIGIBILITY. Only those persons who are employees of the Employer shall be eligible to participate in the Plan. The Committee shall determine from time to time the particular employees of the Employer who shall be eligible to participate in the Plan and the extent of their participation therein. No option shall be granted under the Plan to any employee of the Employer who, at the time such option is granted, owns shares possessing more than ten percent (10%) of the total combined voting power of all classes of shares of the Company or of any parent or subsidiary corporation of the Company or any parent or subsidiary corporation of any of the foregoing (such employee being hereinafter referred to as a "10% Shareholder"), except as provided below. In determining whether the percentage limitations of this paragraph are met, an employee shall be considered as owning any shares owned, directly or indirectly, by or for his brothers or sisters (whether by the whole or half blood), spouse, ancestors, and lineal descendants. For purposes of this paragraph 3, shares owned, directly or indirectly, by or for a corporation, partnership, estate, or trust shall be considered as being owned proportionately by or for its shareholders, partners, or beneficiaries. The percentage limitations of this paragraph 3 shall not apply, however, if at the time such option is granted the option price is at least one hundred ten percent (110%) of the fair market value of the shares subject to the option and such option by its terms is not exercisable after the expiration of five (5) years from the date such option is granted.


4. SHARES. The shares subject to the options and other provisions of the Plan shall be shares of the Company's authorized, but unissued, or reacquired Common Shares (the "Common Shares"). The total amount of the Common Shares on which options may be granted shall not exceed in the aggregate Ninety-Five Thousand (95,000) shares, except as such number of shares shall be adjusted in accordance with the provisions set forth in paragraph 6(g) hereof. In the event any outstanding option under the Plan expires or is terminated for any reason prior to the end of the period during which options may be granted, the Common Shares allocable to the unexercised portion of such option may again be subject to an option under the Plan. During the period that any options granted hereunder are outstanding, the Employer shall reserve and keep available such number of Common Shares as will be sufficient to satisfy all outstanding, unexercised options.

5. MAXIMUM EXERCISE RULE

The aggregate fair market value (determined at the time the option is granted) of the shares with respect to which incentive stock options are exercisable for the first time by an employee during any calendar year under all such plans of the Employer and any parent or subsidiary corporation of the Employer shall not exceed One Hundred Thousand Dollars ($100,000.00).

6. TERMS AND CONDITIONS OF OPTIONS. Options granted pursuant to the Plan shall be evidenced by agreements in such form as the Committee shall from time to time prescribe, which agreements shall comply with and be subject to the following terms and conditions:

(a) MEDIUM AND TIME OF PAYMENT. The option price shall be payable in United States dollars upon the exercise of the option and shall be paid (i) in cash; (ii) by certified check or by bank cashier's check; (iii) through the tender to the Company of Common Shares of the Company or through the withholding of Common Shares of the Company that are subject to the option, which Common Shares shall be valued, for purposes of determining the extent to which the purchase price has been paid, at their fair market value on the date of exercise as determined in Section 6(c); or (iv) by a combination of the methods described in (i), (ii), or (iii); provided, however, that the Committee may in its discretion impose and set forth in the option agreement pertaining to an option such limitations or prohibitions on the use of Common Shares to exercise options as it deems appropriate. Fair market value of the Common Shares shall be determined by the Committee in the same manner that it is determined in establishing option prices. Payment of the option price shall be accompanied by a written subscription agreement in a form to be prescribed by the Committee.

(b) NUMBER OF SHARES. The option agreement shall state the total number of shares to which it pertains, and the date of the grant of the option. The Committee may prescribe in the option agreement a minimum number of Common Shares with respect to which an option may be exercised, in whole or in part.

(c) OPTION PRICE. The option price shall be an amount per share not less than the fair market value per share of the Common Shares on the date of granting of the option.

-2-

In the case of options granted to an employee of the Employer who is a 10% Shareholder, the option price shall be an amount per share not less than one hundred ten percent (110%) of the fair market value per share of the Common Shares on the date of the granting of the option. Fair market value shall mean, if the price of the Common Shares is so reported, the closing price for the Common Shares on the National Association of Securities Dealers Automated Quotation System or any exchange on which the Common Shares are then traded, as reported in The Wall Street Journal (Midwest Edition). If the price of Common Shares is not so reported, fair market value shall be determined, in good faith, by the Committee in accordance with such procedures as the Committee shall from time to time prescribe.

(d) TERM OF OPTIONS. The term of each option granted under the Plan shall expire within the period prescribed in the agreement relating thereto, which shall not be more than five (5) years from the date the option is granted if the optionee is a 10% Shareholder and not more than ten (10) years from the date the option is granted if the optionee is not a 10% Shareholder.

(e) DATE OF EXERCISE. Each option shall be exercisable as determined by the Committee and set forth in an option agreement, provided, however, that any such limitation on the exercise of an option contained in an option agreement may be rescinded, modified, or waived by the Committee, in its sole discretion, at any time and from time to time after the date of grant of such option so as to accelerate the time in which the option may be exercised. Except as specifically restricted by the Committee, any option may be exercised in whole at any time or in part from time to time during its term.

(f) TERMINATION OF EMPLOYMENT. In the event an optionee shall cease to be employed by the Employer, a parent corporation of the Employer, or a corporation or a parent or a subsidiary corporation of such corporation issuing or assuming an option in a transaction to which Section 424(g) of the Code applies, all options outstanding in the hands of the optionee shall terminate immediately as to any unexercised portion thereof; provided, however, that if any cessation of employment is due to retirement with the consent of the Employer or permanent and total disability, the optionee shall have the right, subject to the provisions of paragraph 6(d) and paragraph 6(e) hereof, to exercise the option, with respect to the shares for which it could have been exercised on the effective date of his cessation of employment, at any time within three (3) months after such cessation of employment due to retirement with the consent of the Employer or at any time within twelve (12) months after such cessation of employment due to permanent and total disability; and provided further, that if the employee shall die while in the employ of the Employer, the employee's personal representative shall have the right, subject to the provisions of paragraph 6(d) and paragraph 6(e) hereof, to exercise the option with respect to the shares for which it could have been exercised on the date of death, at any time within twelve (12) months from the date of death. Whether a cessation of employment is to be considered a retirement with the consent of the Employer or due to permanent and total disability, and whether an authorized leave of absence or absence on military or government service shall be deemed to constitute

-3-

termination of employment, for the purposes of the Plan, shall be determined by the Committee, which determination shall be final and conclusive.

(g) RECAPITALIZATION. The aggregate number of Common Shares on which options may be granted hereunder, the number of shares thereof covered by each outstanding option, and the price per share thereof in each such option, shall all be proportionately adjusted for any increase or decrease in the number of issued Common Shares resulting from a subdivision or consolidation of shares or any other capital adjustment, the payment of a share dividend, or other increase or decrease in the Common Shares effected without receipt of consideration by the Employer. In the event that, prior to the delivery by the Employer of the Common Shares remaining under any outstanding option hereunder, there shall be a capital reorganization or reclassification of the capital of the Employer resulting in a substitution of other shares for the Common Shares, there shall be substituted the number of substitute shares which would have been issued in exchange for the Common Shares then remaining under the option if such Common Shares had been then issued and outstanding.

(h) MERGER, DISSOLUTION. If the Employer shall be a party to any merger or consolidation, the Employer shall have the right to terminate any option outstanding on thirty (30) days written notice; provided, however, if such merger or consolidation is not consummated within 180 days from the date of the aforementioned notice, all options terminated shall be deemed to have been continuously in effect since the date of execution thereof. In the event of a dissolution or liquidation of the Employer, the Employer shall give each optionee thirty (30) days written notice thereof; every unexercised option outstanding hereunder shall be deemed to be terminated upon such dissolution or liquidation.

(i) ASSIGNABILITY. No option shall be assignable or transferable except by will or under the laws of descent and distribution. During the lifetime of an optionee, the option shall be exercisable only by the optionee.

(i) ISSUANCE OF SHARES AND COMPLIANCE WITH SECURITIES LAWS. The Employer may postpone the issuance and delivery of certificates representing shares until (a) the admission of such shares to listing on any stock exchange on which shares of the Employer of the same class are then listed and (b) the completion of such registration or other qualification of such shares under any state or federal law, rule or regulation as the Employer shall determine to be necessary or advisable, which registration or other qualification the Employer shall use its best efforts to complete; provided, however, a person purchasing shares pursuant to the Plan has no right to require the Employer to register the Common Shares under federal or state securities laws at any time. Any person purchasing shares pursuant to the Plan may be required to make such representations and furnish such information as may, in the opinion of counsel for the Employer, be appropriate to permit the Employer, in light of the existence or non-existence with respect to such shares of an effective registration under the Securities Act of 1933, as amended, or any similar state statute, to issue the shares in compliance with the provisions of those or any comparable acts.

-4-

(k) RIGHTS AS A SHAREHOLDER. An optionee shall have no rights as a shareholder with respect to shares covered by an option until the date of issuance of a certificate to him and only after such shares are fully paid. No adjustment will be made for dividends or other rights for which the record date is prior to the date such certificate is issued.

(l) OTHER PROVISIONS. The option agreements entered into under the Plan shall contain such other provisions as the Committee shall deem advisable.

7. TERM OF PLAN. The Plan shall become effective upon the approval by the holders of a majority of the issued and outstanding shares of each class of the voting shares of the Company voting in person or by proxy at a duly held shareholders' meeting; provided, however, that the Plan shall become effective only if approved by such shareholders within twelve (12) months before or after the date the Plan is adopted by the Company's Board of Directors. The Board of Directors may, in its sole discretion, terminate the Plan at any time with respect to any shares as to which options have not been granted. No option shall be granted under the Plan thereafter.

8. AMENDMENT OF THE PLAN. The Board of Directors of the Company may from time to time, alter, amend, suspend, or discontinue the Plan with respect to any shares as to which options have not been granted; provided, however, that the Board of Directors may not, without further approval by the holders of a majority of the issued and outstanding shares of each class of voting shares of the Company:

(a) increase the maximum number of shares as to which options may be granted under the Plan (other than to reflect a stock split or stock dividend);

(b) change the class of shares for which options may be granted under the Plan; or

(c) change the provisions of paragraph 6(c) concerning the option price.

9. APPLICATION OF FUNDS. The proceeds received by the Company from the sale of shares pursuant to options granted hereunder will be used for general corporate purposes.

10. NO OBLIGATION TO EXERCISE OPTION. The granting of an option hereunder shall impose no obligation upon the optionee to exercise such an option.

11. CONTINUANCE OF EMPLOYMENT. Neither the adoption of the Plan nor the granting of an option hereunder shall impose any obligation on the Employer to continue the employment of an optionee.

12. APPLICABILITY OF AMENDMENTS. All outstanding options shall be deemed to be amended so as to include, to the extent applicable thereto, any amendments made to the Plan subsequent to the granting of such options.

-5-

13. WITHHOLDINGS. The Committee shall have the right to require optionees to remit to the Company amounts sufficient to satisfy any federal, state or local income tax withholding requirements (or make other arrangements satisfactory to the Company with regard to such taxes) at such times as the Company deems necessary or appropriate for compliance with such laws.

WITNESSETH THAT:

WHEREAS, in the interests of affording an incentive to the Grantee to give his best efforts to the Company as a key employee, the Company wishes to provide that the Grantee shall have an option to buy Common Shares of the Company:

NOW, THEREFORE, it is hereby mutually agreed as follows:

1. The Company hereby grants to the Grantee the right and option to purchase, on the terms and conditions hereinafter set forth, all or any part of an aggregate of __________shares (hereinafter called "Subject Shares") of the presently authorized, but unissued, or treasury, Common Shares of the Company (hereinafter called the "Common Shares"), at a purchase price of $______ per share, exercisable in whole or in part from time to time subject to the limitation that no option may be exercised with respect to fewer than twenty-five (25) shares unless there are fewer than twenty-five (25) shares then subject to option hereunder, in which event any exercise must be as to all such shares and subject to the further limitation that the options represented by this Agreement


shall be exercisable in four equal installments as set forth in Section 6(e) of the Plan. The option shall expire as to all shares subject to purchase hereunder on the ______ anniversary date of this Agreement if not exercised on or before such date.
2. Subject to the limitation specified in Section 1 hereof and in
Section 6(e) of the Plan, the Grantee may from time to time exercise this option by delivering a written notice of exercise and subscription agreement to the Secretary of the Company specifying the number of whole shares to be purchased, accompanied by payment (i) in cash, (ii) by certified check or bank cashier's check, (iii) through the tender to the Company of Common Shares of the Company owned by the optionee or by withholding of Common Shares of the Company that are subject to the option, which Common Shares shall be valued, for purposes of determining the extent to which the purchase price has been paid, at their fair market value on the date of exercise as determined in
Section 6(c) of the Plan; or (iv) by a combination of the methods described in
(i), (ii), or (iii). The Company may, in its sole discretion, refuse to withhold Common Shares of the Company as payment of the exercise price of the option. Such exercise shall be effective upon receipt by the Secretary of such written notice, subscription agreement and payment of the purchase price. Only the Grantee may exercise the option during the lifetime of the Grantee. No fractional shares may be purchased at any time hereunder.
3. Upon the effective exercise of the option, or any part thereof, certificates representing the shares so purchased, marked fully paid and non-assessable, shall be delivered to the person who exercised the option, except as provided in Section 6(j) of the Plan. Until certificates representing such shares shall have been issued and delivered, the Grantee shall not have any of the rights or privileges of a shareholder of the Company in respect of any of such shares.

-2-

4. In the event that, prior to the delivery by the Company of all the Subject Shares, there shall be an increase or reduction in the number of Common Shares of the Company issued and outstanding by reason of any subdivision or consolidation of Common Shares or any other capital adjustment, the number of shares then subject to this option shall be increased or decreased as provided in Section 6(g) of the Plan.
5. The option and the rights and privileges conferred by this Option Agreement shall not be assigned or transferred by the Grantee in any manner except by will or under the laws of descent and distribution. In the event of any attempted assignment or transfer in violation of this Section 5, the option, rights and privileges conferred by this Option Agreement shall become null and void.
6. Nothing herein contained shall be deemed to create any limitation or restriction upon such rights as the Company would otherwise have to terminate a person as an employee of the Company.
7. The option, rights and privileges herein conferred are granted subject to the terms and conditions set forth herein and in the Plan.
8. Any notices to be given or served under the terms of this Option Agreement shall be addressed to the Secretary of the Company at 2701 Kent Avenue, West Lafayette, Indiana, and to the Grantee at the address set forth on page one of this Option Agreement, or such other address or addresses as either party may hereafter designate in writing to the other. Any such notice shall be deemed to have been duly given or served, if and when enclosed in a properly sealed envelope or wrapper addressed as aforesaid, postage prepaid, and deposited in the United States mail.

9. The interpretation by the Incentive Stock Option Committee, appointed by the Company's Board of Directors, of any provisions of the Plan or of this Option Agreement shall be final and binding on the Grantee unless otherwise determined by the Company's Board of Directors.

(i) "Outside Director" means any director of the Company or an Affiliate who is not employed by the Company or any Affiliate in any capacity.

(j) "Plan" means this 1997 Bioanalytical Systems, Inc. Outside Director Stock Option Plan.

2. PURPOSE. This Plan is intended to be an incentive to, and to encourage ownership of the Common Shares by, Outside Directors of the Company and its Affiliates in order to provide such Outside Directors with a more direct and proprietary interest in the welfare and success of the Company and to encourage their continuation as directors of the Company. The Plan is further intended to promote continuity of membership on the Board of Directors and to increase the incentive to promote the welfare of the Company by those who are primarily responsible for shaping and


carrying out the long-term plans and objectives of the Company, thereby furthering and securing the Company's continued growth and financial success. It is contemplated that only Nonstatutory Stock Options will be granted under the Plan.

3. ADMINISTRATION. The Plan shall be administered by the Committee which shall consist of three or more members of the Board of Directors who are appointed from time to time by the Board of Directors. The Board of Directors may from time to time remove members from, or add members to, the Committee. Vacancies on the Committee, howsoever caused, shall be filled by the Board of Directors. The Committee shall have the power (a) to interpret and construe the provisions of the Plan or any option granted under it, and such interpretation or construction shall be final and binding; (b) to select Outside Directors to whom grants of options under the Plan shall be made as more particularly set forth in paragraph 4 hereof; (c) to determine the terms and conditions of each option granted hereunder; (d) to determine the time at which such grants shall be made and the number of Common Shares to be optioned under such grant; and (e) to make any other determinations regarding the Plan which are not otherwise expressly provided herein. The Committee may prescribe, amend and rescind rules and regulations relative to the Plan or its construction or interpretation. A majority of the Committee shall constitute a quorum. All determinations of the Committee shall be made by the vote of a majority of its members; provided, however, that if there are fewer than three
(3) members of the Committee at any time, all determinations shall be a joint determination of its members. No member of the Committee shall be liable for any action or determination made in good faith.

4. ELIGIBILITY. Only those persons who are Outside Directors shall be eligible to participate in the Plan. The Committee shall determine from time to time the particular Outside Directors who shall be eligible to participate in the Plan and the extent of their participation therein.

5. SHARES. The shares subject to the options and other provisions of the Plan shall be the Company's authorized, but unissued, or reacquired Common Shares. The total number of the Common Shares on which options may be granted under the Plan shall not exceed in the aggregate five thousand (5,000) shares, except as such number of shares shall be adjusted in accordance with the provisions set forth in paragraph 6(g) hereof. In the event any outstanding option under the Plan expires or is terminated for any reason prior to the end of the period during which options may be granted, the Common Shares allocable to the unexercised portion of such option may again be subject to an option under the Plan. During the period that any options granted hereunder are outstanding, the Company shall reserve and keep available such number of Common Shares as will be sufficient to satisfy all outstanding, unexercised options.

(a) MEDIUM AND TIME OF PAYMENT. The option price shall be payable in United States dollars upon the exercise of the option and shall be paid (i) in cash; (ii) by

-2-

certified check or by bank cashier's check; (iii) through the tender to the Company of Common Shares of the Company or through the withholding of Common Shares of the Company that are subject to the option, which Common Shares shall be valued, for purposes of determining the extent to which the purchase price has been paid, at their fair market value on the date of exercise as determined in
Section 6(c); or (iv) or by a combination of (i), (ii) or (iii); provided, however, that the Committee may in its discretion impose and set forth in the option agreement pertaining to an option such limitations or prohibitions on the use of Common Shares to exercise options as it deems appropriate. Fair market value of any Common Shares surrendered or withheld shall be determined by the Committee in the same manner that it is determined in establishing option prices. Payment of the option price shall be accompanied by a written subscription agreement in a form to be prescribed by the Committee.

(b) NUMBER OF SHARES; DATE OF GRANT. The option agreement shall state the total number of shares to which it pertains, and the date of the grant of the option. The Committee may prescribe in the option agreement a minimum number of Common Shares with respect to which an option may be exercised, in whole or in part.

(c) OPTION PRICE. The option price shall be an amount per share not less than the fair market value per share of the Common Shares on the date of grant of the option. Fair market value shall mean, if the price is so reported, the closing price for the Common Shares on the National Association of Securities Dealers Automated Quotation System or any exchange on which the Common Shares are then traded, as reported in The Wall Street Journal (Midwest Edition). If the price of Common Shares is not so reported, fair market value shall be determined, in good faith, by the Committee in accordance with such procedures as the Committee shall from time to time prescribe.

(d) TERM OF OPTIONS. Each option granted under the Plan shall expire within the period prescribed in the agreement relating thereto, which shall not be more than ten (10) years from the date the option is granted.

(e) TIME OF EXERCISE. Each option granted pursuant to the Plan shall be exercisable in four equal installments. The option may be exercised as to the shares covered by the first installment from and after the second anniversary of the grant of the option, with second, third and fourth installments becoming exercisable on the three succeeding anniversary dates; provided, however, that any such limitation on the exercise of an option contained in an option agreement may be rescinded, modified or waived by the Committee, in its sole discretion, at any time and from time to time after the date of grant of such option so as to accelerate the time in which the option may be exercised. Except as specifically restricted by the provisions of this paragraph 6(e) or by the Committee acting hereunder, any option may be exercised in whole at any time or in part from time to time during its term.

-3-

(f) CESSATION OF SERVICE AS A DIRECTOR. In the event an Optionee ceases to serve as a director of the Company or an Affiliate all options outstanding in the hands of the Optionee shall terminate immediately as to any unexercised portion thereof; provided, however, that if any cessation of service is due to retirement with the consent of the Company or is due to permanent and total disability, the Optionee shall have the right, subject to the provisions of paragraphs 6(d) and 6(e) hereof, to exercise the option, with respect to the Common Shares for which it could have been exercised on the effective date of the Optionee's cessation of service, at any time within three (3) months after such cessation of service due to retirement with the consent of the Company or at any time within twelve (12) months after such cessation of service due to permanent and total disability; and provided further, that if the Optionee shall die while serving as a director of the Company or an Affiliate, the Optionee's personal representative shall have the right, subject to the provisions of paragraphs 6(d) and 6(e) hereof, to exercise the option with respect to the Common Shares for which the option could have been exercised on the date of death, at any time within twelve (12) months from the date of the Optionee's death. Whether a cessation of service is a retirement with the consent of the Company or due to permanent and total disability, and whether an authorized leave of absence or absence on military or government service shall be deemed to constitute cessation of service for the purposes of the Plan, shall be determined by the Committee in its sole discretion, which determination shall be final and conclusive.

(g) RECAPITALIZATION. The aggregate number of Common Shares on which options may be granted hereunder, the number of Common Shares covered by each outstanding option, and the price per share set forth in each option agreement, shall all be proportionately adjusted for any increase or decrease in the number of issued Common Shares resulting from a subdivision or consolidation of shares of the Company or any other capital adjustment of the Company, the payment of a share dividend, a share split or any other increase or decrease in the Common Shares effected without receipt of consideration by the Company. In the event that, prior to the delivery by the Company of the Common Shares remaining unexercised under any outstanding option hereunder, there shall be a capital reorganization or reclassification of the capital of the Company resulting in a substitution of other shares for the Common Shares, there shall be substituted the number of substitute shares which would have been issued in exchange for the Common Shares then remaining under the option if such Common Shares had been then issued and outstanding.

(h) MERGER, DISSOLUTION. If the Company shall be a party to any merger or consolidation, the Company shall have the right to terminate any option outstanding on thirty (30) days' written notice; provided, however, if such merger or consolidation is not consummated within 180 days from the date of the aforementioned notice, all options terminated shall be deemed to have been continuously in effect since the date of execution thereof. In the event of a dissolution or liquidation of the Company, the Company shall give each optionee thirty (30) days written notice specifying the effective date thereof. Every unexercised option outstanding hereunder on the date set by the Company as the effective

-4-

date of the dissolution or liquidation shall be deemed to be terminated upon such dissolution or liquidation.

(i) NONASSIGNABILITY. No option granted under the Plan shall be assignable or transferable except by will or under the laws of descent and distribution. During the lifetime of an Optionee, the option shall be exercisable only by the Optionee.

(j) ISSUANCE OF SHARES AND COMPLIANCE WITH SECURITIES LAWS. The Company may postpone the issuance and delivery of certificates representing Common Shares until (a) the admission of such shares to listing on any stock exchange on which shares of the Company of the same class are then listed and (b) the completion of such registration or other qualification of such shares under any state or Federal law, rule or regulation or the rules and regulations of any exchange upon which the Common Shares are treated as the Company shall determine to be necessary or advisable, which registration or other qualification the Company shall use its best efforts to complete; provided, however, a person purchasing Common Shares pursuant to the Plan has no right to require the Company to register the Common Shares under federal or state securities laws at any time. Any person purchasing Common Shares pursuant to the Plan may be required to make such representations and furnish such information as may, in the opinion of counsel for the Company, be appropriate to permit the Company, in light of the existence or non-existence with respect to such shares of an effective registration under the Securities Act of 1933, as amended, or any similar state statute, to issue the shares in compliance with the provisions of those or any comparable acts.

(k) RIGHTS AS A SHAREHOLDER. An Optionee shall have no rights as a shareholder with respect to Common Shares covered by an option until the date of issuance of a certificate to the Optionee. The certificate shall not be issued until the Optionee has exercised the option and has fully paid for the Common Shares acquired thereby. No adjustment will be made for dividends or other rights for which the record date is prior to the date such certificate is issued.

(l) OTHER PROVISIONS. The option agreements entered into under the Plan shall contain such other provisions, limitations, restrictions and requirements as the Committee shall deem advisable.

7. TERM OF PLAN. The Plan shall become effective upon the date the Plan is adopted by the Board of Directors. The Plan shall terminate ten
(10) years after the date the Plan is adopted by the Board of Directors, or on such earlier date as the Board of Directors may determine. No option shall be granted under the Plan after such termination date.

8. AMENDMENT OF THE PLAN. The Board of Directors may from time to time, alter, amend, suspend, or discontinue the Plan with respect to any Common Shares as to which options have not been granted; provided, however, that no action may be taken hereunder which

-5-

would alter or impair any of the rights or obligations of the Company or any Optionee with respect to any outstanding option without the consent of the Optionee thereof.

9. APPLICATION OF FUNDS. The proceeds received by the Company from the sale of Common Shares pursuant to options granted hereunder will be used for general corporate purposes.

10. NO OBLIGATION TO EXERCISE OPTION. The granting of an option hereunder shall impose no obligation upon the Optionee to exercise such an option.

11. NO RIGHT TO REELECTION. Neither the adoption of the Plan, the granting of an option hereunder, nor any other action taken relating to the Plan shall impose any obligation on the Company or any Affiliate or the Board of Directors of either to nominate any Outside Director for reelection as a director by the shareholders of the Company or any Affiliate.

12. APPLICABILITY OF AMENDMENTS. All outstanding options shall be deemed to be amended so as to include, to the extent applicable thereto, any amendments made to the Plan subsequent to the granting of such options.

13. WITHHOLDINGS. The Committee shall have the right to require the Optionee to remit to the Company amounts sufficient to satisfy any applicable withholding requirements set forth in the Code or under state or local law relating to options granted to the Optionee. The Company shall have the right, to the extent permitted by law, to deduct from any payment of any kind otherwise due to an Optionee who exercises an option any federal, state or local taxes of any kind required by law to be withheld with respect to the Common Shares subject to such option.
