share data in this Prospectus have been adjusted to reflect (i) the conversion
of all outstanding shares of the Company's Series A Preferred Stock (the

                                  THE COMPANY
 
     Applied Analytical Industries, Inc. ("AAI" or the "Company") is a leading
provider of product development and support services to the worldwide
pharmaceutical and biotechnology industries, offering a broad range of
integrated, value-added services that span the drug life cycle, from new
compound characterization and synthesis to marketed-product compliance and
quality control testing. In addition, through its internal development program,
the Company leverages its expertise to generate additional revenue by licensing
internally developed drugs and drug technologies to third parties. To date, AAI
has contributed to the submission, approval or continued marketing of more than
1,250 client products worldwide. As part of its internal development program,
the Company has licensed nine products to clients, including four products
approved by the FDA, and patented ten drug technologies. Since 1991, the
Company's annual net income has increased from $602,000 to $3.2 million, an
average compound annual growth rate of 52%. AAI believes that its reputation for
high quality, innovative and efficient services, skilled professional staff,
state-of-the-art facilities and equipment and expertise in performing critical
development and support services, as well as its focus on internal drug and drug
technology development, position it for continued growth.
 
     The Company competes in the contract research and development industry
(commonly referred to as the contract research organization, or CRO, industry)
which provides independent product development and marketed-product support
services to the drug industry. These research and development services include
compound synthesis/extraction, screening and pharmacological testing,
toxicology/safety testing, formulation development, laboratory testing, clinical
trials management, regulatory, compliance and quality control testing. The
Company estimates that 1994 drug industry research and development expenditures
exceeded $30 billion and that approximately $13 billion was spent on the type of
services offered by the Company. The Company estimates that in 1994
approximately $3.5 billion of research and development spending was outsourced
by the drug industry and that the factors influencing increased outsourcing are
applicable across the range of services. Certain segments of this industry with
low barriers to entry, such as clinical trials management, have significantly
grown in terms of size and number of competitors. In contrast, the Company
believes that its industry segment, which has high barriers to entry such as
large capital investment and scientific and technical expertise, has few firms
that offer a broad range of services. The Company believes that significant
market opportunities exist for service providers in its market segment and that
it is well positioned to compete.
 
     The Company provides a broad range of integrated, value-added services,
including chemical analysis, synthesis and other laboratory services; drug
formulation development; clinical supply and niche manufacturing; and regulatory
and compliance consulting. Over the past five years, AAI has provided services
to 24 of the top 25 pharmaceutical companies in the world as ranked by 1994
research and development spending. In 1995, the Company provided services under
approximately 850 contracts to approximately 220 clients, including some of the
largest U.S., European and Japanese drug companies. The Company is currently
providing critical development services for 48 products intended for submission
to or under review by the U.S. FDA.
 
     In addition to its core fee-for-service business, AAI is leveraging its

technology development, in which the Company shares in the expense of
development and participates in the benefits of any potential commercial success
through licensing arrangements. Internal drug development is focused primarily
on generic products. The Company anticipates that the sales growth in the U.S.
generic drug market from $3.5 billion in 1990 to $6.4 billion in 1994 will
continue as managed care organizations continue policies favoring generic
substitution and patents on many high revenue products expire over the next
several years. The Company's internal drug development efforts have resulted in
12 generic product applications filed with the FDA. Applications for six of
those products have been approved in its clients' names, of which four products
are currently licensed to clients and two products have been sold. Licensing
arrangements for these products vary as to amounts of initial and milestone
payments, as well as methods and extent of revenue participation. The Company's
proprietary technology includes ten patents and four pending patent applications
on formulations and methods, including liquid formulations for improved delivery
of nonsteroidal anti-inflammatory drugs or NSAIDs, such as ibuprofen, and
chewable formulations to mask the otherwise bitter taste of certain ulcer drugs.
The Company has two licensing arrangements for its proprietary technologies and
is seeking licensing partners for its other recently developed technologies.
 
     Since 1993, the Company has allocated a growing proportion of its technical
resources and operating capacity to its internal drug and technology development
program and because of the significant time required for development and
approval of pharmaceutical products, the Company has only recently begun to
recognize significant license revenue from its internal development efforts. In
1994, as part of its internal development program, the Company organized
Endeavor Pharmaceuticals, Inc. ("Endeavor") to develop certain generic hormone
pharmaceutical products, focusing initially on several such products then under
development by AAI. The Company owns approximately 38% of the fully diluted
common equity of Endeavor.
 
     The Company's strategy is to continue to invest in the personnel,
facilities, technology and information systems necessary to continue to provide
high quality services spanning the development process and to continue to
leverage its development expertise to expand internal development of drugs and
technologies. By continuing to expand the scope of services offered, the Company
intends to cover most aspects of pharmaceutical and biotechnology product
development, offering clients an opportunity to use one service provider for
seamless product development and support. The Company intends to establish a
presence in certain domestic and international markets to access additional
pools of talented professional and technical personnel and to reduce regulatory
or logistical obstacles in performing certain client services. The Company plans
to continue its commitment to expand its information systems technology and is
currently operating a pilot-phase system with certain domestic and international
clients to provide secured, on-line access to in-progress laboratory data to
enhance clients' efficiency in monitoring and changing the scope and format of
projects. Finally, the Company will continue to invest a significant proportion
of its capabilities in internal drug and technology development with the
objective of licensing marketing rights to third parties. Although there is a
risk that any particular development project may not produce revenues, the
Company believes that the profit margins from successful drug and technology
development projects potentially exceed the margins on standard fee-for-service
engagements.
 
     The Company's principal executive offices are located in Wilmington, North
Carolina, and the Company maintains operating facilities in Wilmington and
Research Triangle Park, North Carolina and sales offices in Chicago, Illinois;
Boston, Massachusetts; San Francisco, California; Elmwood Park, New Jersey and
San Juan, Puerto Rico. The Company also maintains sales offices in Copenhagen,
Denmark; London, England and Milan, Italy to better serve and develop its
European client base.

     income taxes commencing as of January 1, 1991. The Pro Forma data also
     reflects the capitalization of the Company on a pro forma basis to give
     effect to the 200-for-one split of the Common Stock and Class B Common
     Stock effected on May 31, 1996 and the one-for-.6325 split of the Common

                                  RISK FACTORS
 
     In addition to the other information contained in this Prospectus, the
following risk factors should be carefully considered in evaluating the Company
and its business before purchasing the Common Stock offered hereby.
 
DEPENDENCE ON AND EFFECT OF GOVERNMENT REGULATION
 
     The design, development, testing, manufacturing and marketing of
pharmaceutical compounds, biotechnology products, medical nutrition and
diagnostic products and medical devices are subject to regulation by
governmental authorities, including the U.S. Food and Drug Administration (the
"FDA") and comparable regulatory authorities in other countries. The Company's
business depends in part on strict government regulation of the drug development
process, especially in the United States. Proposed legislation has been recently
introduced in the U.S. Congress to substantially modify regulations administered
by the FDA governing the drug approval process. Under the proposed legislation,
applications for approval of drugs could be made to private, accredited
facilities in lieu of the FDA, 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 approval procedures could adversely affect the Company's business. See
"Business -- Government Regulation".
 
     The drug approval process is generally lengthy, expensive and subject to
unanticipated delays. Currently, the Company is assisting in the development of
a number of products subject to regulatory approval for which it has the right
to receive license fees or otherwise participate in sales revenues. Continued
growth in AAI's revenues and profits will depend, in part, on the successful
introduction of some or all of such products. There can be no assurance as to
when or whether such approvals from regulatory authorities will be received.
 
     All facilities and manufacturing techniques used for the manufacturing of
products for clinical use or for sale in the United States must be operated in
conformity with current Good Manufacturing Practices ("GMP") regulations, the
FDA regulations and guidelines governing the development and production of
pharmaceutical products. The Company's facilities are subject to scheduled
periodic regulatory inspections to ensure compliance with GMP requirements.
Failure on the part of the Company to comply with applicable requirements could
result in termination of ongoing research or the disqualification of data for
submission to regulatory authorities. A finding that the Company had materially
violated GMP requirements could result in additional regulatory sanctions and,
in severe cases, could result in a mandated closing of the Company's facilities
which would materially and adversely affect the Company. See
"Business -- Industry Overview" and "-- Government Regulation".
 
MANAGEMENT OF GROWTH AND ACQUISITION RISKS
 
     The Company has experienced rapid growth over the past ten years. The
Company believes that this growth may strain operational, human and financial
resources. In order to manage internal growth, AAI must continue to improve its
operating and administrative systems and to attract and retain qualified
management and professional, scientific and technical operating personnel.
Failure to manage growth effectively could have a material adverse effect on the
Company's business.
 
     The Company reviews acquisition opportunities in the ordinary course of its
business. Acquisitions involve numerous risks, including difficulties in the
assimilation of the operations and services of the acquired companies, the
expenses incurred in connection with the acquisition and subsequent assimilation
of operations and services, the diversion of management's attention from other
business concerns and the potential loss of key employees of the acquired
company. Acquisitions of foreign companies also may involve the additional risks
of, among others, assimilating differences in foreign business practices and
regulations, overcoming language barriers and managing currency exchange risk.
There can be no assurance that the Company's acquisitions will be successfully
integrated into the Company's operations. In addition, there can be no assurance
that the Company will complete any future acquisitions or
 
                                        7
<PAGE>   12
 
that acquisitions will contribute favorably to the Company's operations and
financial condition. See "Business -- Strategy".
 
DEPENDENCE ON CERTAIN INDUSTRIES AND CLIENTS
 
     The Company's revenues are highly dependent on research and development
expenditures and production-related compliance testing expenditures by the
pharmaceutical and biotechnology industries. AAI has benefited from the growing
tendency of pharmaceutical and biotechnology companies to engage independent
organizations to conduct development and testing projects. The Company's
operations could be materially and adversely affected by a general economic
decline in these industries or by any reduction in the outsourcing of research,
development and testing activities.
 
     The Company believes that concentration of business in its industry is not
uncommon. AAI has experienced such concentration in the past and may experience
such concentration in the future. During 1995, Aesgen, Inc. (an affiliate of the
Company), a major U.S.-based pharmaceutical company and Endeavor (a venture 38%
owned by the Company) accounted for approximately 16.0%, 11.2% and 10.2%,
respectively, of the Company's net sales. During the first three months of 1996,
one client (Endeavor) accounted for approximately 15.8% of the Company's net
sales, with Aesgen, Inc. accounting for 6.9% of net sales. There can be no
assurance that the Company's business will not continue to be dependent on
certain clients or that annual results would not be dependent upon performance
of a few large projects for specific clients. Generally, the Company's
fee-for-service contracts are terminable by the client upon notice of 30 days or
less. 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 results. The loss of
business from a significant client could have a material adverse effect on the
Company. Aesgen and Endeavor are early-stage development companies and their
revenues are dependent upon product approvals. Neither Aesgen, Inc. nor Endeavor
has received any product approvals to date, and continued product development by
these firms is dependent upon their obtaining product approvals or additional
capital funding. See "Business -- Factors Influencing Increased Outsourcing" and
"-- Clients".
 
VARIATION IN QUARTERLY OPERATING RESULTS
 
     The Company's results of operations historically have fluctuated on a
quarterly basis and can be expected to continue to be subject to quarterly
fluctuations. Quarterly results can fluctuate as a result of a number of
factors, including the timing of the receipt of licensing revenues, including
royalties, the timing of startup expenses for new ventures or for internal
development projects with outsourced clinical trials, the completion,
commencement or cancellation of significant contracts, progress of ongoing
contracts and mix of services. The Company believes that quarterly comparisons
of its financial results are not necessarily meaningful and should not be relied
upon as an indication of future performance. In addition, fluctuations in
quarterly results could affect the market price of the Common Stock in a manner
unrelated to the longer term operating performance of the Company. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Quarterly Results".
 
DEPENDENCE ON KEY PERSONNEL
 
     The Company relies on a number of key executives, including Frederick D.
Sancilio, Ph.D., its President and Chairman of the Board. In addition to his
duties at AAI, Dr. Sancilio serves as a senior management employee of Endeavor,
a company in which AAI owns 38% of the common equity on a fully diluted basis.
Dr. Sancilio does not maintain an office or have day-to-day responsibilities at
Endeavor and devotes a substantial majority of his time to the management of
AAI. The Company maintains key man life insurance on Dr. Sancilio in the amount
of $3.0 million. The Company's performance depends on its ability to attract and
retain qualified management and professional, scientific and technical operating
staff. The loss of the services of any of AAI's key executives could have a
material and adverse effect on the Company. There also can be no assurance that
AAI will be able to continue to attract and retain qualified staff. See
"Business -- Employees".

<PAGE>   13
 
POTENTIAL LIABILITY AND RISKS OF OPERATIONS
 
     AAI develops, formulates, tests and, to a limited extent, manufactures
pharmaceutical products intended for use by the public. Such activities could
expose the Company to risk of liability for personal injury or death to persons
using such products, although the Company does not commercially market or sell
the products. The Company is currently involved in the commercial manufacture of
one pharmaceutical product and may manufacture pharmaceutical products for
third-party commercial distribution on a limited basis or as a service to its
clients transitioning to internal production. Such activity could increase the
Company's risk of personal injury liability. The Company seeks to reduce its
potential liability through measures such as contractual indemnification
provisions with clients (the scope of which may vary from client to client and
the performances of which are not secured) and insurance maintained by clients.
The Company could be materially and adversely affected if it were required to
pay damages or incur defense costs in connection with a claim that is outside
the scope of the indemnification agreements, if the indemnity, although
applicable, is not performed in accordance with its terms or if the Company's
liability exceeds the amount of applicable insurance or indemnity. In addition,
the Company could be held liable for errors and omissions in connection with the
services it performs. The Company currently maintains product liability and
errors and omissions insurance with respect to these risks. In addition, the
Company's proposed expansion of services to include clinical trials of products
in humans and introduction of proprietary products in clinical trials may expose
it to additional risk of liability. See "Business -- Potential Liability and
Insurance".
 
COMPETITION
 
     The Company competes primarily with the in-house research, development,
quality control and other support service departments of pharmaceutical and
biotechnology companies and with university research laboratories, many of which
have substantially greater resources than the Company. In addition, the CRO
industry is highly fragmented, consisting of several hundred small, limited
service providers and a few large, global firms. The Company competes against
these companies, some of which may have substantially greater resources than the
Company. As a result of competitive pressures, the CRO industry is
consolidating. This trend is likely to produce increased competition for both
clients and acquisition candidates. Increased competition may lead to increased
price and other forms of competition that may adversely affect the Company.
Competitive factors include reliability, turn-around time, reputation for
innovative and quality science, capacity to perform numerous required services,
financial viability and price. See "Business -- Competition".
 
DEPENDENCE ON THIRD-PARTY MARKETING AND DISTRIBUTION
 
     The Company has developed, and intends to continue internal development of
drugs to be licensed to third parties for marketing and distribution. The
Company does not intend to market or commercially distribute such products.
Accordingly, the success of internal development activities depends upon the
Company's ability to enter into marketing arrangements with third parties. There
can be no assurance that such arrangements can be successfully negotiated or
that any such arrangements will be available on commercially reasonable terms.
Even if acceptable and timely marketing arrangements are available, there can be
no assurance that products developed by the Company will be accepted in the
marketplace. In addition, because the Company's marketing licensee will in many
cases make all or many material marketing and other commercialization decisions
regarding such products, a significant number of the variables that may affect
the Company's license fees and royalties, and, therefore, net income, will not
be within the Company's control.
 
UNCERTAINTY OF THIRD-PARTY REIMBURSEMENT; PRICING PRESSURE
 
     The Company's license fees, royalties and other revenue may depend, in
part, on the availability of reimbursement from third-party payors, such as
government health administration authorities, private health insurers and other
organizations. Third-party payors are increasingly challenging the price and
cost-effectiveness of medical products and services. There can be no assurance
that adequate third-
 
                                        9
<PAGE>   14
 
party reimbursement will be available to achieve or maintain price levels
sufficient to realize an appropriate return on the Company's investment in
product development.
 
     In addition, global efforts to contain healthcare costs, particularly among
managed care organizations, continue to exert downward pressure on product
pricing. Further, a number of regulatory and legislative proposals aimed at
changing the healthcare industry in the United States and other countries have
been proposed. There can be no assurance that private sector reform or
governmental healthcare reform measures, if adopted, will not have a negative
impact upon the Company and its operations.
 
PROPRIETARY TECHNOLOGY; UNPREDICTABILITY OF PATENT PROTECTION
 
     The Company's success will depend, 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
and, if challenged, will be held valid. In addition, there can be no assurance
that any technologies or products developed by AAI will not be challenged by
third parties owning patent rights and, if challenged, will be held to not
infringe such patent rights. The expense involved in any patent litigation can
be significant and cannot be estimated by the Company. Finally, if the Company
relies on unpatented, proprietary technology, there can be no assurance that
others will not independently develop or obtain similar products or
technologies.
 
FUTURE CAPITAL REQUIREMENTS; UNCERTAINTY OF ADDITIONAL FUNDING
 
     The Company has developed substantial scientific and technical
infrastructure to provide a broad array of services to the pharmaceutical and
biotechnology industries. The Company expects capital and operating expenditures
to increase over the next several years as it continues to pursue its growth
strategy. Although the Company believes that the net proceeds from this
Offering, existing cash and investment securities 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 acquisitions made by the Company, the rate of
internal growth and the amount and timing of revenue from proprietary products
and technology. 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. No assurance can be given that additional financing will be
available when needed, or that, if available, such financing will be obtained on
terms favorable to the Company or its stockholders. To the extent the Company
raises additional capital by issuing equity securities, ownership dilution to
stockholders will result. See "Use of Proceeds", "Business -- Strategy" and
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Liquidity and Capital Resources".
 
TRANSACTIONS WITH AFFILIATES; CONFLICTS OF INTEREST
 
     The Company provides product development and other services to Aesgen, Inc.
("Aesgen"), which develops generic pharmaceutical products. Approximately 30% of
Aesgen's outstanding common stock is held by a corporation owned by holders of
substantially all of the Company's outstanding shares of capital stock. The
Company holds a $1.6 million non-convertible, non-voting preferred stock
investment in Aesgen. In addition, Frederick D. Sancilio, a director of the
Company and its President and Chief Executive Officer, and James L. Waters and
Charles D. Moseley, Jr., non-employee directors of the Company, serve as three
of the ten directors of Aesgen. In addition, under the development agreement
between Aesgen and the Company, the Company has agreed in certain circumstances
not to develop a formulation for its own account or for any other person of any
generic pharmaceutical product that the Company has agreed and agrees to develop
for Aesgen. The Company also provides development services to Endeavor.
Approximately 42% of Endeavor's fully diluted common equity is beneficially
owned by certain holders of the Company's Preferred Stock which is convertible
into approximately 19% of the Common Stock. The Company owns approximately 38%
of the fully diluted common equity of Endeavor. Dr. Sancilio and William H.
Underwood, executive officers and directors of the Company, and two other
 
                                       10
<PAGE>   15
 
executive officers of AAI serve on the nine-member board of directors of
Endeavor. In addition, Mr. Moseley, an outside director of the Company, serves
on Endeavor's board of directors. The Company leases its headquarters facility
from a company in which Dr. Sancilio and Mr. Waters each owns a one-third
interest. Rental fees under the lease are subject to adjustment for increases in
certain expenses in operating and insuring the facility. Various conflicts of
interest could arise between such related parties and the Company. The Company's
Restated Certificate of Incorporation which will become effective upon
completion of this Offering includes certain provisions addressing potential
conflicts of interest between the Company and entities in which a director or
executive officer has a financial interest. See "Certain Transactions" and
"Description of Capital Stock -- Delaware Law and Certain Provisions of the
Company's Restated Certificate of Incorporation and By-laws".
 
CONCENTRATION OF OWNERSHIP
 
     Following this Offering, assuming that the Underwriters' over-allotment
option is not exercised, certain of the Company's executive officers will
beneficially own approximately 34.4% of the outstanding shares of Common Stock,
and certain of the Company's non-employee directors will beneficially own
approximately 17.2% of the outstanding shares of Common Stock. Accordingly, such
persons will be in a position to influence the election of the Company's
directors and the outcome of corporate actions requiring stockholder approval.
This concentration of ownership may have the effect of delaying or preventing a
change in control of the Company. See "Management" and "Principal Stockholders".
 
NO PRIOR MARKET; POSSIBLE VOLATILITY OF STOCK PRICE
 
     Prior to this Offering, there has been no public market for the Company's
Common Stock, and there can be no assurance that an active trading market will
develop or be sustained after this Offering. The initial public offering price
was determined through negotiations between AAI and the Underwriters and may not
represent prices which will prevail in the trading market. The market price of
the Company's Common Stock could be subject to wide fluctuations in response to
variations in operating results from quarter to quarter, changes in earnings
estimates by analysts and market conditions in the industry and general economic
conditions. 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 Company's Common Stock. See "Underwriting".
 
SHARES ELIGIBLE FOR FUTURE SALE
 
     Sales of a substantial number of shares of the Company's Common Stock in
the public market after this Offering could adversely affect the market price of
the shares of Common Stock. Of the 15,881,709 shares of Common Stock to be
outstanding upon completion of this Offering, assuming the Underwriters'
over-allotment option is not exercised, the 2,700,000 shares offered hereby will
be freely tradeable without restriction unless held by affiliates of the
Company. Taking into consideration the effect of lock-up agreements entered into
by certain stockholders of the Company, 10,439,875 shares will become eligible
for sale beginning 180 days after the date of effectiveness of the registration
statement of which this Prospectus is a part, subject to the provisions of Rule
144 under the Securities Act of 1933, as amended (the "Securities Act"), or Rule
701 under the Securities Act. The remaining 2,636,331 shares of Common Stock
will become eligible for sale under Rule 144 at various dates thereafter as the
holding period provisions of Rule 144 are satisfied. The Company has granted
options to purchase a total of 450,444 shares of Common Stock, which are subject
to vesting in installments over 42 months. Certain holders of the Company's
capital stock are entitled to rights with respect to the registration under the
Securities Act of all shares of Common Stock (13,076,206 shares) currently held
or to be acquired upon conversion of shares of Preferred Stock and Class B
Common Stock. See "Description of Capital Stock -- Registration Rights" and
"Shares Eligible for Future Sale".

BROAD DISCRETION AS TO USE OF PROCEEDS
 
     The Company intends to use the net proceeds of this Offering for capital
expenditures (including expansion of facilities, acquisition of equipment and
improvement of information systems technology), geographic expansion, possible
future acquisitions, working capital and other general corporate purposes. Most
of the net proceeds will be available for projects that are not yet identified
and the management of the Company will have discretion with respect to the
application of such proceeds. Pending such uses, the Company intends to invest
the net proceeds from this Offering in short-term, investment-grade,
interest-bearing securities. See "Use of Proceeds".
 
CERTAIN ANTI-TAKEOVER PROVISIONS; POSSIBLE ISSUANCE OF PREFERRED STOCK
 
     The Company's Restated Certificate of Incorporation and By-laws, which will
become effective upon the completion of this Offering, contain certain
provisions that may have the effect of deterring a future takeover of the
Company, including the classification of the Board of Directors into three
classes. These provisions could limit the price that certain investors might be
willing to pay in the future for shares of Common Stock. In addition, 10,000,000
shares of the Company's preferred stock may be issued in the future without
further stockholder approval and upon such terms and conditions, and having such
rights, privileges and preferences, as the Board of Directors of the Company may
determine. The issuance of preferred stock, while providing desirable
flexibility in connection with possible acquisitions and other corporate
purposes, could adversely affect the market price of shares of Common Stock and
could have the effect of making it more difficult for a third party to acquire,
or discouraging a third party from acquiring, a majority of the outstanding
voting stock of the Company. AAI has no present plans to issue any shares of
preferred stock. In addition, Section 203 of the Delaware General Corporation
Law, to which the Company will be subject upon completion of this Offering,
restricts certain business combinations with any "interested stockholder" as
defined by such statute. The statute may delay, defer or prevent a change in
control of the Company. See "Description of Capital Stock".
 
DILUTION
 
     Purchasers of Common Stock in this Offering will experience immediate and
substantial dilution in the net tangible book value per share of the Common
Stock. See "Dilution".

                                  THE COMPANY
 
     AAI is a leading integrated contract research and development resource to
the pharmaceutical and biotechnology industries, offering an efficient,
variable-cost alternative to its clients' internal drug development, compliance
and quality control programs. The Company provides a broad array of value-added
services, including chemical analysis, synthesis and other laboratory services;
drug formulation development; clinical supply and niche manufacturing; and
regulatory and compliance consulting. Since it was founded in 1979, AAI has
contributed to the submission, approval or continued marketing of more than
1,250 client products worldwide, encompassing a wide range of therapeutic
categories and technologies. The Company is currently providing critical
development services for 48 products intended for submission to or under review
by the FDA. The Company believes that its ability to offer an extensive
portfolio of high quality drug development and support services enables it to
effectively compete as pharmaceutical and biotechnology companies look for
integrated drug development solutions that offer cost-effective results on an
accelerated basis.
 
     In addition to its core fee-for-service business, AAI is leveraging its
expertise by allocating a significant proportion of its technical resources and
operating capacity to internal drug and drug technology development, in which
the Company shares in the expense of development and participates in the
benefits of any potential commercial success through licensing arrangements.
Internal drug development is focused primarily on generic products. The
Company's internal product development efforts have resulted in 12 generic
product applications filed with the FDA. Applications for six of those products
have been approved in its clients' names, of which four products are currently
licensed to clients and two products have been sold. The Company's proprietary
technology includes ten patents and four pending patent applications on
formulations and methods, including liquid formulations for improved delivery of
nonsteroidal anti-inflammatory drugs or NSAIDs, such as ibuprofen, and chewable
formulations to mask the otherwise bitter taste of certain ulcer drugs. Since
1993, the Company has committed a growing proportion of its technical resources
on internal development and because of the significant time required for
development and approval of pharmaceutical products, the Company has only
recently begun to recognize significant license revenue from its internal
development efforts.
 
     In 1994, as part of its internal development program, the Company organized
Endeavor to develop certain hormone pharmaceutical products, focusing initially
on several generic hormone products then under development by AAI. The Company
owns approximately 38% of the fully diluted common equity of Endeavor.
 
     The Company was incorporated in 1986, although its corporate predecessor
was initially founded in 1979. The Company's principal executive offices are
located at 5051 New Centre Drive, Wilmington, North Carolina 28403, and its
telephone number is (910) 392-1606.
 
     As used in this Prospectus, the terms "Company" and "AAI" include Applied
Analytical Industries, Inc., its corporate predecessors and its subsidiaries,
except where the context indicates otherwise.

                                USE OF PROCEEDS
 
     The net proceeds to the Company from the sale of the 2,700,000 shares of
Common Stock offered by the Company hereby are estimated to be $31,743,000
($36,639,450 if the Underwriters' over-allotment option is exercised in full),
assuming the shares offered hereby are sold at an initial public offering price
of $13.00 per share and after deducting the estimated underwriting discount and
offering expenses. The Company intends to use the net proceeds of this Offering
for capital expenditures (including expansion of facilities, acquisition of
equipment and improvement of information systems technology), geographic
expansion, possible future acquisitions, working capital and other general
corporate purposes. Pending such uses, the Company intends to invest the net
proceeds from this offering in short-term, investment-grade, interest-bearing
securities.
 
     The Company intends to pursue opportunities to acquire businesses offering
services similar or complementary to those offered by the Company. While the
Company regularly evaluates acquisition opportunities, the Company has no
present understandings, agreements or commitments that would require the use of
the net proceeds of this Offering with respect to any such transaction. On May
28, 1996, the Company entered into a six-month option agreement to acquire a
European contract research and development organization subject to satisfaction
of material contingencies. Significant uncertainties exist whether such
conditions could be satisfied prior to the expiration of the option. The Company
does not intend to exercise the option if such conditions are not satisfied. In
addition, the Company may not exercise the option even though such conditions
may be satisfied. The purchase of this firm upon exercise of the option would
not require the use of any of the net proceeds of this Offering, and the Company
does not intend to apply any of the net proceeds of this Offering to fund such
acquisition, if completed. There can be no assurance that this or any other
future acquisitions will be consummated. See "Risk Factors -- Management of
Growth and Acquisition Risks" and "Management's Discussion and Analysis of
Financial Condition and Results of Operations -- Liquidity and Capital
Resources".
 
                                DIVIDEND POLICY
 
     Prior to November 17, 1995, the Company was an S corporation for federal
income tax purposes and prior to such time periodically declared and paid cash
dividends to its stockholders in amounts approximately sufficient to permit its
stockholders to pay their income taxes on earnings of the Company that were
treated as having been earned by the Company's stockholders and in 1995 an
additional monthly dividend totaling $14,000 per month. In addition, in
connection with the termination of the Company's status as an S corporation, the
Company declared a cash dividend in the aggregate amount of approximately $7.1
million, approximating the Company's accumulated adjustments account for federal
income tax purposes as of such date. Of such dividend, $5.8 million was paid to
stockholders prior to December 31, 1995 and the remainder will be paid prior to
the completion of this Offering.
 
     The Company intends to retain future earnings, if any, to finance the
development and expansion of its business and, therefore, does not anticipate
paying any cash dividends on its Common Stock in the foreseeable future. The
decision whether to pay cash dividends will be made by the Board of Directors of
the Company in the light of conditions then existing, including the Company's
results of operations, financial condition and requirements, business conditions
and other factors.

                                    DILUTION
 
     The pro forma net tangible book value of the Company as of March 31, 1996,
assuming the conversion of all outstanding shares of Preferred Stock and Class B
Common Stock into shares of Common Stock and the exercise of all stock options
outstanding on the date of this Prospectus, as if such options had been granted
and exercised on March 31, 1996, was $23.8 million, or $1.78 per share of Common
Stock. "Pro forma net tangible book value per share" is determined by dividing
the pro forma number of outstanding shares of Common Stock into the net tangible
book value of the Company (total tangible assets less total liabilities). After
giving effect to the sale by the Company of the 2,700,000 shares of Common Stock
offered hereby (based upon an assumed initial public offering price of $13.00
per share and after deducting the estimated underwriting discount and offering
expenses), the as adjusted net tangible book value of the Company as of March
31, 1996 would have been $55.6 million, or $3.45 per share. This represents an
immediate increase in net tangible book value of $1.67 per share to existing
stockholders and an immediate dilution of $9.55 per share to new investors. The
following table illustrates the per share dilution:

     The selected financial data for the three years ended December 31, 1995,
have been derived from the Company's consolidated financial statements, which
have been audited by Price Waterhouse LLP, independent accountants. The selected
historical financial data for the two years ended December 31, 1992 have been
derived from the Company's financial statements, which have been audited by
another independent accounting firm. The selected financial data for the three

unaudited consolidated financial statements and include, in the opinion of
management, all normal recurring adjustments necessary to present fairly the
data for such periods. The operating results for the three months ended March
31, 1996, are not necessarily indicative of the results that may be expected for
the full fiscal year ending December 31, 1996. This information should be read

          MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                           AND RESULTS OF OPERATIONS
 
OVERVIEW
 
     The Company derives its revenue primarily from performing contract product
development and support services for the pharmaceutical and biotechnology
industries, including chemical analysis, synthesis and other laboratory
services; drug formulation development; clinical supply and niche manufacturing;
and regulatory and compliance consulting. In general, the Company provides
services to a client under an estimate that establishes anticipated price and
scope of a project, although estimates may be adjusted during the term of the
project. The terms of the Company's engagements vary, ranging from less than one
month to several years, and generally may be terminated upon notice of 30 days
or less by the client. The Company recognizes revenue on the percentage of
completion basis as work is performed.
 
     In addition to its core fee-for-service business, the Company has allocated
a growing proportion of its technical resources and operating capacity to
internal drug and drug technology development projects. These projects are
either internally funded or shared-risk projects with development partners. The
Company has applied a portion of the net proceeds from its issuance of Preferred
Stock in November 1995 and intends to use a portion of the net proceeds of this
Offering to expand its capacity to enable growth in its internal development
program, as well as its core fee-for-service business. Internal development
projects are undertaken to develop targeted drugs and proprietary drug
technologies with the intention of licensing the marketing rights to third
parties. The Company has also entered into selective shared-risk development
projects, reducing its fees for development services in return for license fees,
typically paid upon performance of certain milestones, and royalties based on a
percentage of product sales or profit. Substantially all of the Company's
research and development expense are the result of internal development and
shared-risk projects.
 
     The Company has only recently begun to recognize significant license
revenue from its internal development efforts due to the significant time
required for development and approval of pharmaceutical products. Historically,
as the Company expanded its internal development program, less capacity was
available for fee-for-service work to generate more immediate revenue. The
Company anticipates that licensing revenue, including royalties, from internal
drug and technology development will represent a larger proportion of its
revenue, although there can be no assurance that internal development projects
will yield products that will be approved by the appropriate regulatory
authorities or will be attractive to potential clients. The Company believes
that the profit margins from internal drug and technology development
potentially exceed the margins on its standard core fee-for-service engagements.
 
     In 1994, the Company and private investors organized Endeavor to fund the
development of generic hormone pharmaceutical products, which initially focused
on certain products then under development by the Company. The Company owns
approximately 38% of the fully diluted common equity of Endeavor and continues
the development of these products under agreements with Endeavor. The Company's
net sales to Endeavor were approximately $1.9 million, $3.5 million and $1.6
million in 1994, 1995 and the three months ended March 31, 1996, respectively.
The Company also provides development services to Aesgen, an affiliate, and
recognized net sales to Aesgen of $5.6 million and $688,000 in 1995 and for the
three months ended March 31, 1996, respectively. See "Risk Factors -- Dependence
on Certain Industries and Clients" and "Certain Transactions -- Transactions
Involving Management".
 
     The Company accounts for its investment in Endeavor under the equity method
which limits the recognition of losses to the amount invested or committed for
investment and financial support. The Company acquired its equity interest in
Endeavor in return for its contribution of existing formulations and technology
developed by the Company that had been fully expensed. Other investors' cash
contribution to Endeavor created a gain for AAI that was deferred. In connection
with its investment, the Company extended a $1.5 million revolving credit
facility to Endeavor. Because of this financial support commitment under the
credit facility, the Company recognized a liability during 1994 and the first
three quarters
 
                                       18
<PAGE>   23
 
of 1995 equal to its proportionate share of Endeavor's operating losses, net of
amortization of the deferred gain on the original investment. In connection with
a cash investment by new investors in November 1995, loans under this facility
were repaid during the fourth quarter of 1995 and the Company's obligation to
make further loans was terminated. As a result of the termination of the
Company's obligation to make further loans to Endeavor under the credit
facility, the previously recorded liability was reversed in the fourth quarter
of 1995. See Note 3 of Notes to Consolidated Financial Statements.
 
     Effective November 17, 1995, upon the issuance of the Preferred Stock the
Company ceased to be treated as an S corporation for federal and state income
tax purposes.
 
     This Prospectus contains certain forward-looking statements that involve
risks and uncertainties. The Company's actual results may differ significantly
from the results discussed in those forward-looking statements. Factors that
might cause such differences include those discussed in "Risk Factors".

</TABLE>
 
  THREE MONTHS ENDED MARCH 31, 1996 COMPARED TO THREE MONTHS ENDED MARCH 31,
1995
 
     Net sales increased $1.6 million, or 19% to $9.9 million in the first
quarter of 1996 compared to the first quarter of 1995. The increase was
primarily due to the recognition of $650,000 in revenue upon the licensing of
formulations and related data and marketing rights for two proprietary
pharmaceutical products in development and to the performance of a greater
number of projects, primarily for analytical services.
 
     Cost of sales increased by $492,000, or 14%, to $4.1 million for the first
quarter of 1996 compared to the first quarter of 1995. Cost of sales decreased
as a percentage of net sales to 41.5% from 43.6%, reflecting the recognition of
the $650,000 in licensing revenue in 1996, the associated cost of which
primarily had been recognized in prior periods.
 
     Selling expense increased by $275,000, or 22%, to $1.5 million in the first
quarter of 1996 compared to the first quarter of 1995. The increase was
primarily attributable to the opening of sales offices in Boston, Massachusetts;
San Francisco, California; Copenhagen, Denmark; and London, England, as well as
higher commission expense associated with increased sales. General and
administrative expense increased by $176,000, or 8%, to $2.3 million in the
first quarter of 1996 compared to the first quarter of 1995. The increase in
general and administrative expense is primarily due to increased patent research
expenses in support of the Company's research and development program. As a
percentage of sales, the Company's general and administrative expense continued
its downward trend, decreasing to 22.9% for the first quarter of 1996 from 25.2%
for the first quarter of 1995.
 
                                       19
<PAGE>   24
 
     Research and development expense increased by $201,000, or 31%, to $852,000
in the first quarter of 1996 compared to the first quarter of 1995, and
represented 8.6% of net sales for the 1996 period compared to 7.8% of net sales
in the 1995 quarter. The increase in research and development expense reflects
the Company's decision to allocate an increasing proportion of its development
capabilities to its internal development program. The Company anticipates that,
consistent with its business strategy, investments in research and development
will continue to increase over the next several years.
 
     Other expense, net, which was primarily interest expense, decreased by
$143,000, or 83%, to $29,000 in the first quarter of 1996 compared to the first
quarter of 1995 due to the reduced borrowing levels during the 1996 period
compared to 1995. In addition, interest income from marketable securities,
purchased with a portion of the net proceeds of the issuance of the Preferred
Stock, offset expense incurred with respect to the Company's remaining
interest-bearing liabilities.
 
     As a result of the termination of the Company's obligations under the
credit facility to Endeavor during the fourth quarter of 1995, the Company
recognized no loss associated with its investment in Endeavor during the first
three months of 1996, compared with a loss of $462,000 for the comparable period
in 1995.
 
     Income taxes for the first quarter of 1996 were $454,000. No income taxes
were recognized for the first quarter of 1995 because the Company was treated as
an S corporation for federal and state income tax purposes throughout such
period.
 
  FISCAL 1995 COMPARED TO FISCAL 1994
 
     Net sales increased by $1.8 million, or 5%, to $34.6 million in 1995
compared to 1994. The increase in net sales was primarily attributable to a
greater number of fee-for-service projects undertaken by the Company. These
increases were partially offset by a $1.8 million reduction of net sales to a
single customer from the winding down of one project and by the Company's
decision to allocate an increasing proportion of its technical resources and
operating capacity to internal research and development projects.
 
     Cost of sales declined by $274,000, or 2%, to $14.3 million in 1995
compared to 1994. Cost of sales as a percentage of net sales decreased to 41.2%
in 1995 from 44.2% in 1994. This decrease is primarily attributable to the high
level of cost of sales in 1994 associated with increases in professional
staffing in 1994 and with the opening of the Company's Research Triangle Park
facility in 1994.
 
     Selling expense increased by $523,000, or 12%, to $4.9 million in 1995
compared to 1994. Such increase is primarily the result of the full-year impact
of increases in the sales and marketing personnel implemented in 1994. Selling
expense as a percent of net sales increased to 14.2% in 1995 compared to 13.4%
in 1994 reflecting the delay in productivity as new sales personnel were trained
and established relationships with prospective clients.
 
     General and administrative expense decreased by $314,000, or 4%, to $8.2
million in 1995 compared to 1994 primarily as a result of reductions in the
level of executive compensation and the departure in 1995 of certain employees
to manage an affiliate. General and administrative expense as a percentage of
net sales continued its downward trend, decreasing to 23.6% in 1995 from 25.8%
in 1994. The Company believes that such trend reflects the compensation
reductions discussed above and the utilization of administrative leverage during
the period, with the expansion of operating facilities requiring no significant
increase in administrative staffing or management information systems. Such
trend may not continue in the near term, as management anticipates selected
increases in administrative staffing and information technology spending to
support the Company's continued growth.
 
     Research and development expense increased $932,000, or 39%, to $3.3
million in 1995 compared to 1994. Research and development expense represented
9.6% of net sales in 1995 compared to 7.3% of net sales in 1994. The increase in
research and development expense reflects the Company's decision to allocate an
increasing proportion of its development capabilities to proprietary products.
 
                                       20
<PAGE>   25
 
     Other expense increased by $690,000 to $1.1 million in 1995 compared to
1994, reflecting higher interest expense from increased borrowing levels during
1995 and a provision of $363,000 established in connection with litigation,
currently under appeal, with a former employee of the Company terminated in
1992.
 
     Equity income of $444,000 was recognized in 1995 with respect to the
Company's investment in Endeavor, reversing equity losses of $444,000 in 1994,
due to the termination in 1995 of the Company's obligation to provide Endeavor
funding under the credit facility. See Note 3 of Notes to Consolidated Financial
Statements.
 
  FISCAL 1994 COMPARED TO FISCAL 1993
 
     Net sales increased by $6.5 million, or 25%, to $32.9 million in 1994
compared to 1993. The increase is attributable to an increase in the number of
projects performed by the Company in 1994, as well as a $2.6 million increase in
net sales resulting from a multi-year, quality control project commenced in mid-
1993 for a single client.
 
     Cost of sales increased by $4.8 million, or 49%, to $14.5 million in 1994
compared to 1993 principally due to the costs associated with the opening of the
Company's Research Triangle Park facility in 1994. These costs included the cost
of hiring and training additional staff, validation of the new facilities and
increased lease expense.
 
     Selling expense increased by $736,000, or 20%, to $4.4 million in 1994
compared to 1993, primarily as a result of increases to the sales and marketing
personnel made in 1994 and higher promotional spending.
 
     General and administrative expense decreased by $253,000, or 3%, to $8.5
million in 1994 compared to 1993. The reduction in general and administrative
expense was primarily due to decreases in the level of executive compensation in
1994 compared to 1993, partially offset by increased staffing in several
administrative departments.
 
     Research and development expense increased by $1.1 million, or 88%, to $2.4
million in 1994 compared to 1993, as the Company continued its 1993 initiative
to increase internal proprietary product and technology development activities.
Research and development expense as a percentage of net sales increased to 7.3%
in 1994 from 4.8% in 1993, reflecting the initiation of several new product
development programs and increased spending for continuing technology
development programs.
 
     Other expense, primarily interest expense, increased by $284,000 to
$440,000 in 1994 compared to 1993 primarily due to increased borrowing levels in
1994 compared to 1993.
 
     Equity losses of $444,000 in 1994 were attributable to the Company's
investment in Endeavor.
 
QUARTERLY RESULTS
 
     The Company's quarterly results have been, and are expected to continue to
be, subject to fluctuations. Quarterly results can fluctuate as a result of a
number of factors, including the commencement, completion or cancellation of
large contracts, progress of ongoing contracts, recognition of licensing
revenue, acquisitions, the timing of start-up expenses for new facilities and
changes in the mix of services. Since a large percentage of the Company's
operating costs are relatively fixed, variations in the timing and progress of
large contracts or the recognition of licensing revenue (on projects for which
associated expense was recognized in prior periods) can materially affect
quarterly results. In addition, recognition of equity income or loss from the
Company's investment in Endeavor in any quarter could substantially affect net
income. To the extent the Company's international business increases, exchange
rate fluctuations may also influence these results. The Company believes that
comparisons of its quarterly financial results are not necessarily meaningful
and should not be relied upon as an indication of future performance. See "Risk
Factors -- Variation in Quarterly Operating Results".

LIQUIDITY AND CAPITAL RESOURCES
 
     The Company has funded its business through operating cash flows, proceeds
from borrowings and the issuance of shares of Preferred Stock in November 1995.
During 1993, 1994 and 1995, the Company generated $544,000, $4.9 million and
$3.8 million, respectively, in cash flow from operations and raised $21.5
million in net proceeds in 1995 from the issuance of shares of Preferred Stock.
 
     Total capital expenditures were $2.3 million in 1993, $3.1 million in 1994,
$1.7 million in 1995 and $1.1 million in the first three months of 1996. Capital
expenditures were incurred predominantly in connection with the opening of the
Company's Research Triangle Park facility and with improvements made to existing
facilities. The Company anticipates capital expenditures in 1996 to be
approximately $8.4 million, to be used in part for the expansion of clinical
supply and niche manufacturing facilities scheduled to be completed in the
second half of 1996 and the first half of 1997.
 
     At December 31, 1995, the Company's working capital was $13.8 million
compared to $569,000 at December 31, 1994. The increase in working capital is
attributable primarily to the receipt of approximately $21.5 million in net
proceeds from the issuance in November 1995 of shares of Preferred Stock and the
application of a portion of the net proceeds to repay certain outstanding debt
and to partially fund a $7.1 million dividend declared in connection with the
termination of the Company's status as an S corporation. The portion of the net
proceeds from the issuance of the shares of Preferred Stock not yet applied for
use is invested in investment-grade, interest-bearing, marketable debt
securities. At March 31, 1996, working capital was $13.7 million, reflecting the
application of a portion of the net proceeds from the issuance of the Preferred
Stock for capital expenditures and other corporate purposes.
 
     The Company has used credit facilities to fund certain capital expenditures
and its short-term liquidity needs. The Company's credit facility with
NationsBank, N.A. (the "Credit Facility") consists of two term loans with a
total of $3.7 million outstanding as of March 31, 1996 and two lines of credit
totaling $5.0 million. The interest rate on loans under the Credit Facility is
30-day LIBOR plus a variable margin based on the Company's debt-to-equity ratio.
At March 31, 1996 the interest rate was 6.87%. Indebtedness under the Credit
Facility is secured by substantially all of the assets of the Company and is
subject to a number of covenants and restrictions relating to, among other
things, financial ratios, other liabilities and indebtedness. Of the $3.7
million in outstanding term loans at March 31, 1996, approximately $2.7 million
matures in December 1997, with monthly payments of $34,167 plus interest, and
$1.0 million matures in December 2000, with monthly payments of $16,663 plus
interest. The amount available
 
                                       22
<PAGE>   27
 
for borrowing under the $5.0 million revolving credit lines is based upon the
amount of certain accounts receivable pledged to secure the indebtedness. At
March 31, 1996, the Company was eligible to borrow $5.0 million, of which $2.0
million was outstanding, under the revolving lines of credit. The revolving
lines of credit are scheduled to expire in August 1996 and are expected to be
renewed for an additional one-year term.
 
     In 1988, the Company obtained $3.5 million in financing through the
issuance of variable-rate industrial revenue bonds backed by a letter of credit.
Interest on the Company's obligation under the bonds varies and the rate at
March 31, 1996 was 3.65%. The Company's obligations under the bonds and to the
bank that issued the letter of credit supporting the bonds mature in November
2000, with monthly payments on the bonds of $25,000 plus interest and annual
letter of credit fees equal to 1% of the outstanding amount of the bonds. At
March 31, 1996, $1.7 million was outstanding under this facility.
 
     In May 1996, the Company acquired an option to purchase the outstanding
stock of a European contract research and development organization. The Company
is obligated to pay approximately $1.0 million by June 27, 1996 to acquire such
option, which amount will be held in escrow and would be applied to the purchase
price if the Company elects to exercise such option or returned to the Company
if, prior to the expiration of the option, certain substantial conditions are
not satisfied. Significant uncertainties exist whether such conditions could be
satisfied prior to the option expiration date, November 28, 1996. The Company
does not intend to exercise such option if these conditions are not satisfied
and can make no prediction whether such conditions will be satisfied by November
28, 1996. In addition, the Company may elect not to exercise such option even if
such conditions are satisfied, in which case it would forfeit the $1.0 million
option payment.
 
     The Company expects to continue expanding its operations through internal
growth and strategic acquisitions. The Company expects such activities will be
funded from existing cash and cash equivalents, cash flow from operations, the
net proceeds from the Offering and borrowings under its Credit Facility. The
Company believes that such sources of cash will be sufficient to fund the
Company's current operations for the foreseeable future. Although the Company
has no present acquisition agreements or arrangements other than described
above, there may be acquisition or other growth opportunities that require
additional external financing, and the Company may from time to time seek to
obtain funds from public or private issuances of equity or debt securities.
There can be no assurances that such financings will be available on terms
acceptable to the Company.
 
INFLATION
 
     The Company believes the effects of inflation generally do not have a
material adverse effect on its results of operations or financial condition.

                                    BUSINESS
 
     AAI is a leading integrated contract research and development resource to
the pharmaceutical and biotechnology industries, offering an efficient,
variable-cost alternative to its clients' internal drug development, compliance
and quality control programs. The Company provides a broad array of value-added
services, including chemical analysis, synthesis and other laboratory services;
drug formulation development; clinical supply and niche manufacturing; and
regulatory and compliance consulting. Since it was founded in 1979, AAI has
contributed to the submission, approval or continued marketing of more than
1,250 client products worldwide, encompassing a wide range of therapeutic
categories and technologies. The Company is currently providing critical
development services for 48 products intended for submission to or under review
by the FDA. The Company believes that its ability to offer an extensive
portfolio of high quality drug development and support services enables it to
effectively compete as pharmaceutical and biotechnology companies look for
integrated drug development solutions that offer cost-effective results on an
accelerated basis.
 
     In addition to its core fee-for-service business, AAI is leveraging its
expertise by allocating a significant proportion of its technical resources and
operating capacity to internal drug and drug technology development, in which
the Company shares in the expense of development and participates in the
benefits of any potential commercial success through licensing arrangements.
Internal drug development is focused primarily on generic products. The
Company's internal product development efforts have resulted in 12 generic
product applications filed with the FDA. Applications for six of those products
have been approved in its clients' names, of which four products are currently
licensed to clients and two products have been sold. The Company's proprietary
technology includes ten patents and four pending patent applications on
formulations and methods, including liquid formulations for improved delivery of
nonsteroidal anti-inflammatory drugs or NSAIDs, such as ibuprofen, and chewable
formulations to mask the otherwise bitter taste of certain ulcer drugs. Since
1993, the Company has committed a growing proportion of its technical resources
on internal development and because of the significant time required for
development and approval of pharmaceutical products, the Company has only
recently begun to recognize significant license revenue from its internal
development efforts.
 
     In 1994, as part of its internal development program, the Company organized
Endeavor to develop certain generic hormone pharmaceutical products, focusing
initially on several products then under development by AAI. The Company owns
approximately 38% of the fully diluted common equity of Endeavor.
 
     The Company's principal executive offices are located in Wilmington, North
Carolina, and the Company maintains operating facilities in Wilmington and
Research Triangle Park, North Carolina and sales offices in San Francisco,
California; Elmwood Park, New Jersey; Boston, Massachusetts; Chicago, Illinois
and San Juan, Puerto Rico. The Company also maintains sales offices in
Copenhagen, London and Milan to better serve and develop its European client
base.
 
INDUSTRY OVERVIEW
 
     The contract research and development industry (typically referred to as
the contract research organization, or CRO, industry) provides independent
product development and support services to the pharmaceutical and biotechnology
industries. In 1994, pharmaceutical and biotechnology companies spent
approximately $30 billion worldwide on research and development. The Company
estimates that in 1994 approximately $13 billion was spent on the type of
research and development services offered by the Company, including chemical
characterization, analysis, synthesis and other laboratory services; drug
formulation development; clinical trials production and manufacturing process
development; and regulatory affairs. In addition, the Company estimates that
worldwide 1994 drug company expenditures on compliance and quality assurance
activities exceeded $3.6 billion. These product development and marketed-product
support services, which are the primary focus of AAI's fee-for-service business,
require extensive technical expertise, significant investment in capital
equipment, and extensive experience in drug development processes, GMP
compliance and in regulatory affairs.
 
                                       24
<PAGE>   29
 
     The CRO industry consists of several hundred service providers operating in
various segments of the market, with many of the larger companies focusing
primarily on managing clinical trials and only a few, such as AAI, offering a
broad array of services. There are significant barriers to entry to providing an
extensive portfolio of services, particularly in the segment of the CRO market
that does not focus primarily on clinical management. These barriers include the
capital investment required for state-of-the-art equipment and facilities, the
employment of skilled and experienced professionals and the development of
expertise in and reputation for performing critical development and support
services consistent with clients' time demands and FDA regulatory requirements.
 
     The Company also participates in the generic drug market through licensing
revenues on internally developed products and its partial ownership of Endeavor.
The U.S. generic drug market has expanded sales from $3.5 billion in 1990 to
$6.4 billion in 1994. Generic drugs accounted for an estimated 46% of
prescriptions dispensed in the U.S. in 1994. The Company anticipates that the
growth in the generic drug market will continue as managed care organizations
continue policies favoring generic substitution and patents on many high
dollar-volume products expire over the next several years.
 
FACTORS INFLUENCING INCREASED OUTSOURCING
 
     The Company estimates that approximately $33 billion was spent on drug
development, compliance and quality control worldwide in 1994 and that
approximately $3.5 billion was outsourced to independent contract service
providers. The Company believes that historically the majority of outsourcing
has been for clinical trials management and that pharmaceutical and
biotechnology companies are increasing outsourcing in non-clinical areas to
control costs and to leverage all aspects of internal development and product
support capabilities. The Company believes that the following factors will
contribute to a continuing increase in outsourcing activities:
 
     COST CONTAINMENT PRESSURES.  Market forces, including a shift toward
managed care, and governmental initiatives have placed significant pressure on
drug companies to limit and reduce drug prices. Pricing pressures have arisen
from increased competition as a result of "me-too" drugs, patent expirations,
generic substitution and increased purchasing power of large buyer groups. The
Company believes that the pharmaceutical and biotechnology industries are
responding to these pressures by downsizing and rationalizing internal research
and development programs, favoring outsourcing as a variable-cost alternative.
Although these factors are driving drug companies to contain costs, drug
companies' needs for development capacity continue. In particular, the need for
additional capacity to increase the speed of new product development, maximizing
the period of marketing exclusivity, and to increase economic returns has driven
the need for outsourced services. In addition, market forces, including the
demand arising from an aging population and the incidence of chronic disorders
and life-threatening conditions such as infectious diseases, including AIDS,
have increased the pressure to develop new products. AAI believes that firms
with an extensive, integrated portfolio of drug development and support services
will have a competitive advantage in the market, as pharmaceutical and
biotechnology companies look for integrated drug development solutions offering
cost-effective results on an accelerated basis.
 
     PATENT EXPIRATIONS.  Patents for products representing $10.5 billion of
1994 U.S. drug sales are scheduled to expire by December 31, 2000. These 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
existing products, combined with internal capacity constraints, is leading
companies to outsource these activities. Further, the Company believes that
these patent expirations are providing generic drug companies with more product
opportunities than their internal development capacity can sustain, resulting in
increased outsourcing. AAI believes that firms offering integrated formulation
development services and expertise in a broad variety of dosage forms will
benefit from this trend.
 
     CONSOLIDATION IN THE PHARMACEUTICAL INDUSTRY.  The pharmaceutical industry
is consolidating as companies seek to reduce costs and increase revenue through
business combinations. Once consoli-
 
                                       25
<PAGE>   30
 
dated, many pharmaceutical companies aggressively manage costs by eliminating
jobs, decentralizing the research and development process and outsourcing in an
effort to reduce the fixed costs associated with internal drug development and
product support.
 
     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. Many
biotechnology companies do not have the necessary in-house resources to conduct
required development and testing. In addition, as a result of recent product
development setbacks encountered by some biotechnology companies, the Company
believes that many biotechnology companies are turning to experienced
development firms for analytical and regulatory expertise. Furthermore, the
number of "virtual" drug development companies with little or no internal
development or support resources have increased substantially over the past five
years. Accordingly, these companies must outsource development and support
services. The Company believes firms with formulation development and
biotechnology expertise will benefit from this trend.
 
     INCREASING GENERIC PRODUCT DEVELOPMENT.  Market opportunities arising with
the large number of impending patent expirations and market forces favoring
generic substitution have recently led many pharmaceutical companies to form
divisions focused exclusively on the development of generic products. These
generic product divisions are often allocated limited internal development
capabilities and must outsource some or all of their development and product
support needs. The Company believes that firms offering a broad array of
integrated development and support services will benefit the most from this
trend.
 
     NEED FOR TECHNICAL EXPERTISE.  Certain new compounds present complex
challenges in drug development, including acceptable profiles for stability,
delivery and other formulation parameters. Given the extensive expertise of
certain independent drug development firms, pharmaceutical and biotechnology
companies increasingly look to these firms for innovative solutions to complex
issues. AAI believes that firms with a reputation for high quality, innovative,
solution-driven contract work, will have a key role in the area of difficult
drug development.
 
     NEED FOR DATA MANAGEMENT EXPERTISE.  Regulatory agencies are increasing the
volume of data required for regulatory filings, as well as requesting increased
access to this data. Furthermore, the FDA is encouraging the use of
computer-assisted filings in an effort to expedite the approval process.
Resource allocations and priorities may lead drug companies to outsource to
firms with automated data management capabilities. The Company believes that
firms that stay abreast of technological innovations and changing regulatory
requirements will have a competitive advantage.
 
     GLOBALIZATION OF THE MARKETPLACE.  Foreign pharmaceutical companies,
particularly firms in Japan and Europe, are increasingly seeking to obtain
approval to market their existing products in the U.S. Due to a lack of
familiarity with the complex U.S. regulatory system and the difficulty in
bringing their operating facilities into FDA-required GMP compliance, foreign
firms are increasingly relying on independent development companies with
experience in the U.S. 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.
 
THE DRUG DEVELOPMENT PROCESS
 
     Under the U.S. regulatory system, the development process for new
pharmaceutical products can be divided into three distinct phases. The
pre-clinical 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
 
                                       26
<PAGE>   31
 
products, a Product License Application ("PLA"), for submission to the FDA
requesting approval to market the drug. The third phase, or post-approval 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, of the
approved product, as well as for generic versions of the approved drug, as the
product approaches expiration of patent or other exclusivity protection.
 
     The following figure illustrates the drug development process and the
component activities involved in each of the three phases. The figure also
illustrates the areas of AAI's service offerings. The process is described in
more detail below.

  THE PRECLINICAL PHASE
 
     The development of a new pharmaceutical agent begins with the discovery or
synthesis of a new molecule. These agents are screened for pharmacological
activity using various animal and tissue models, with the goal of selecting a
lead agent for further development. Additional studies are conducted to confirm
pharmacological activity, to generate safety data and to evaluate prototype
dosage forms for appropriate release and activity characteristics. Protocols for
these studies are designed in anticipation of fulfilling regulatory
requirements. Once the pharmaceutically active molecule is fully characterized,
an initial purity profile of the agent is established. During this and
subsequent stages of development, the agent is analyzed to confirm the integrity
and quality of material produced. In addition, development and optimization of
the initial dosage forms to be used in clinical trials is completed, together
with analytical models to determine product stability and degradation. 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. The IND submission consists of the initial chemistry,
analytical, formulation and animal testing data generated during the preclinical
phase. The review period for an IND submission is 30 days, after which, if no
comments are made by the FDA, the product candidate can be studied in Phase I
clinical trials.
 
     The process for the development of biotechnology products parallels the
process outlined above. Biotechnology products frequently are large proteins,
with activity that is different from the activity of small, organic molecules.
Proteins may be coupled with other biologically active molecules, such as lipids
or sugars, for enhanced or modified biological activity. Biotechnology products
may be composed of the building blocks of DNA. Because of the diversity of the
nature of biotechnology products and their substantial molecular size (usually
hundreds of times larger than small, organic molecules), special technology is
required for their production, as well as their subsequent analysis. In
addition, highly sophisticated analytical techniques are required to
characterize the structure of these molecules.
 
     Biotechnology products, especially proteins, may be produced with living
cells. Purity testing can be complex since living cells may harbor viruses and
other agents. The potential presence of these agents, and the requirement to
establish degradation profiles and identify impurities associated with
production and purification, further require establishing, validating and
conducting specialized tests and assays. Formulation development in this area is
often more complex than for small, organic drug substances. Generally, molecules
produced using recombinant DNA technology are inherently less stable than their
organic counterparts because structural integrity must be maintained through
administration and distribution of the product. Accordingly, certain aspects of
the development process for biotechnology products may be more challenging than
similar aspects encountered in the development of small, organic molecules.
 
  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 which
analysis includes bioanalytical assays to determine the availability and
metabolization of the active ingredient following administration. Prior to
conducting these early stage toxicology trials, the drug sponsor must secure
bulk supply of the active ingredient to support the necessary dosing of the
Phase I trials.
 
     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. These pharmacology trials require scale up for
manufacture of increasingly larger batches of bulk chemical. These batches
require validation analysis to confirm the consistent composition of the
product. 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 the efficacy and long-term safety of the
drug. Throughout the clinical phase, samples of the product made in different
batches are tested for stability to establish shelf life constraints. In
addition, large-scale production protocols and written standard
 
                                       28
<PAGE>   34
 
operating procedures ("SOPs") for each aspect of commercial manufacture and
testing must be developed.
 
     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. An NDA, or PLA, is a comprehensive, multi-volume
application that includes, among other things, the results of all pre-clinical
and clinical studies, information about the drug's composition and the sponsor's
plans for producing, packaging and labeling the drug. The FDA's review may be
accelerated from a few months, for drugs related to life-threatening
circumstances, to many years, with the average review lasting two and one-half
years. Prior to granting approval, the FDA generally conducts an inspection of
the facilities, including outsourced facilities, that will be involved in the
manufacture, packaging, testing and control of the drug product for GMP
compliance. Drugs that successfully complete NDA or PLA review may be marketed
in the United States, subject to all conditions imposed by the FDA.
 
  THE POST-APPROVAL PHASE
 
     Following NDA or PLA 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
product shelf life. 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. Failure to comply with FDA regulations in
manufacture or testing during this phase could result in severe sanctions,
including product recalls or closing of facilities.
 
  PATENT EXPIRATION AND GENERIC DEVELOPMENT
 
     Typically, a drug sponsor obtains patent protection for a new chemical
entity commencing upon initial discovery. Due to the length of the development
and regulatory review processes, a significant portion of the patent exclusivity
period expires prior to the initial marketing of the product. As patent
expiration ensues, the sponsor may extend the brand life of the product by
developing new formulations, including line extensions and improved or extended
dosage forms or strengths, improved taste of an orally administered product,
modifications to drug absorption to reduce the time of onset of therapeutic
activity and improvements to the stability of the product. The new product must
be tested for stability and additional clinical toxicology studies may be
performed. Upon completion of all necessary studies, a supplemental NDA is filed
with the FDA requesting approval to market the modified product.
 
     As a drug's patent expires, the drug is subject to generic competition.
Generic products must be approved by the FDA through the submission of an
Abbreviated New Drug Application ("ANDA"). In general, a generic product is
developed with the goal of being classified by the FDA as therapeutically and
pharmaceutically equivalent to an FDA-approved reference product (i.e., the
innovator's product). Such a rating would permit the substitution of the generic
product by pharmacies for the prescribed reference product. To establish
pharmaceutical equivalence, the generic product must contain the same active
ingredients, be of the same dosage form and provide the same strength and route
of administration as the reference product. The generic formulation must also
satisfy prescribed standards of strength, quality, purity and identity. The FDA
does not require the generic drug sponsor to separately demonstrate the safety
or efficacy of the generic form if it is shown to be pharmaceutically equivalent
and therapeutically equivalent to an existing FDA-approved product. Accordingly,
the development period for generic products is typically shorter when compared
to the review period for new drug products. In addition, the regulatory review
of an ANDA is generally considerably shorter than for an NDA.
 
     As the foregoing figure and discussion illustrate, the drug development
process requires multiple services often conducted in parallel. Any capacity
constraints in any area of the process could severely limit the ability of a
drug company to develop a pipeline of products.

STRATEGY
 
     The Company's objective is to be the leading provider of drug development
and support services to the pharmaceutical and biotechnology industries
worldwide and to continue to leverage its development expertise to expand its
internal development of drugs and drug technologies. The Company believes that
its customer-focused approach enables it to serve as a value-added partner in
solving complex product development problems, providing cost-effective results
on an accelerated basis. Further, its broad services assist clients with
virtually all aspects of product support and GMP compliance during commercial
manufacture. The Company believes that its reputation for high quality,
innovative, reliable and efficient services and its capital investment in
state-of-the-art equipment and facilities, skilled and experienced professional
staff, and expertise in performing critical development and support services
represent barriers to entry in its market. The Company believes that these
factors provide the Company with the opportunity to continue to compete
successfully in this growing market. The Company's strategy is to:
 
  OFFER BREADTH OF HIGH QUALITY SERVICES
 
     The Company consistently invests in personnel, facilities, technology and
information systems to provide its clients with a broad range of high quality
development and support services. AAI has built the internal technical expertise
to address difficult product challenges spanning the drug development process.
For each development project, the Company assigns a team of highly qualified
scientists and technicians that interacts with clients throughout a project's
duration. The Company intends to expand its development capabilities by adding
services that are complementary to its existing product development and support
services. The Company intends to cover most significant aspects of
pharmaceutical and biotechnology product development, offering clients a source
for seamless product development and support.
 
  INVEST IN STATE-OF-THE-ART FACILITIES
 
     The Company intends to continue to invest in state-of-the-art equipment and
facilities to further increase the quality and breadth of its services, as well
as to improve productivity. For example, the Company is currently adding a
containment suite to permit the development of potent compounds that is
scheduled to be completed in the third quarter of 1996. The Company also plans
to enhance its bioanalytical skills by acquiring advanced analytical equipment,
to expand its biotechnology expertise by adding virology capabilities and to
increase its clinical supply manufacturing capabilities by adding facilities for
manufacturing sterile injectable products. The Company intends to invest on an
ongoing basis in advanced and automated equipment and facilities to improve
productivity and quality and maintain its competitive position.
 
  EXPAND GEOGRAPHICALLY
 
     The Company believes that establishing a presence in certain domestic and
international regions will enable the Company to more effectively compete for
services that require rapid turnaround and for certain biotechnology business.
In addition, the Company believes that geographic expansion will offer it access
to additional pools of talented professional and technical staff. Further,
adding facilities outside the U.S. also permits the Company to provide services
without certain regulatory restrictions applicable to delivery and testing of
substances in the U.S. The Company intends to add facilities in the northeast
and on the west coast, as well as in targeted international markets. Geographic
expansion may be accomplished by internal growth, acquisitions or joint
ventures.
 
  LEAD IN INFORMATION TECHNOLOGY
 
     The Company believes that superior information technology is essential to
expand operations geographically and to provide innovative services to clients
to enable clients to better monitor their projects and expedite FDA review.
Accordingly, the Company operates a customized data management
 
                                       30
<PAGE>   36
 
system connects approximately 125 analytical instruments, permitting automated
data capture. In addition, the Company's proprietary laboratory tracking system
("LTS") tracks the status of each project being performed by the Company,
including the time expended by Company personnel for each step of the project,
permitting the Company to quantify capacity issues and schedule additional
projects.
 
     The Company is currently operating a pilot-phase system providing certain
domestic and international clients secure access to in-progress laboratory data.
This system will allow a client to monitor directly the status of its project,
enabling the client to make immediate changes to the scope and format of the
project. The Company believes this system will allow development to be completed
more efficiently and, accordingly, at a lower cost to its clients. In addition,
the Company intends to offer its clients secure, on-line access through the
Internet to review all of the data generated through the development process on
their individual projects. The Company anticipates that this data management
system may lead to shortened FDA-review periods for products submitted by
clients using the Company's system since the FDA will have on-line access to
client data in support of an application. The Company intends to introduce this
service to a broader client group in the first half of 1997.
 
  EXPAND INTERNAL DEVELOPMENT PROGRAM
 
     The Company intends to dedicate a significant proportion of its development
capabilities to internal product and technology development with the objective
of licensing marketing rights to third parties. As part of this strategy, the
Company has entered into selected shared-risk development projects providing for
license payments and royalties following successful completion of the project
based upon net sales or profits. The Company does not intend to independently
commercialize products developed internally or otherwise directly compete with
its clients in the marketing or distribution of products and, accordingly,
believes that its internal development efforts are complementary to its clients'
development needs. Because of the significant time required for development and
approval of pharmaceutical products, the Company has only recently begun to
recognize significant license revenue from its internal drug and technology
development efforts.
 
SERVICES
 
     The Company provides a broad array of drug development services, including
chemical analysis, synthesis and other laboratory services; formulation
development; clinical supply and niche manufacturing; and regulatory and
compliance consulting. The Company assigns project management teams consisting
of customer service representatives and technical employees that meet with
clients at frequent intervals to monitor and guide projects through the
development process. Continual client interaction allows the Company to
efficiently manage the drug development process.
 
     In general, the Company's laboratory services account for approximately one
half of its fee-for-service revenue, although relative amounts vary from year to
year. Formulation development projects and clinical supply and niche
manufacturing generally contribute the major portions of remaining annual fee-
for-service revenue.
 
  LABORATORY SERVICES
 
     In support of drug development and compliance programs, the Company offers
laboratory services to characterize and measure drug components and impurities.
The Company has over 16 years' experience in providing analytical testing
services dedicated exclusively to the drug industry and has developed the
scientific expertise, state-of-the-art equipment and broad range of scientific
methods to accurately and quickly analyze almost any compound or product. The
Company's laboratory services include method development and validation;
stability studies; raw materials and release testing; biotechnology,
microbiology and bioanalytical testing; product characterization and organic
synthesis. In 1995, the Company performed more than 90,000 laboratory tests.
 
     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
 
                                       31
<PAGE>   37
 
compounds. Analytical methods are developed to demonstrate potency, purity,
stability or physical attributes. These methods are validated to assure the data
generated by these methods are accurate, precise, reproducible and reliable and
are used throughout the drug development process and in product support testing.
Of the Company's 463 employees, more than 100 of the Company's scientists (22 of
whom hold Ph.D. degrees) are experienced with method development and validation.
 
     STABILITY STUDIES.  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 27-chamber, state-of-the-art controlled climate GMP facility to
determine the range of storage conditions the product can withstand. 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. The Company's proprietary LTS system
tracks client products maintained at the Company's stability storage facilities
and automatically schedules required testing as pull points occur. As of March
31, 1996, the Company maintained samples for 700 stability studies for clinical
supplies and commercial products.
 
     RAW MATERIALS AND PRODUCT RELEASE TESTING.  The Company offers testing
required by the FDA to confirm that raw materials used in production and
resulting finished products are consistent with established specifications. Due
to the incorporation of "just in time" inventory control systems and variations
in client production schedules, release testing for both raw materials and the
finished product often cannot be scheduled by clients in advance, yet must be
performed immediately. The Company believes that its internal scheduling
systems, analytical laboratory expertise and systems for prompt testing provide
it with a competitive advantage in providing both raw material and batch release
testing. The Company believes that this service enhances its client's confidence
in adopting cost-saving "just-in-time" inventory control systems.
 
     BIOTECHNOLOGY ANALYSIS AND SYNTHESIS.  Although the types of analytical
investigations of biotechnology products are similar to those required for more
traditional pharmaceutical products, the complex molecular structure of many
biotechnology products requires different technology and expertise. The Company
provides a broad array of biotechnology services including both analytical and
biological testing and method development and validation. AAI's breadth of
services allow the Company to rapidly deduce and characterize the complex
structure of the biotechnology product and measure the molecule or its
metabolites in human blood plasma to support clinical trial evaluation. The
Company has expertise in a broad spectrum of biochemical and immunochemical
methods for characterization and analysis of biotechnology drugs. These methods
include amino acid sequencing, amino acid analysis, peptide mapping,
carbohydrate and lipid analysis and electrophoresis. The Company also has
expertise in developing chromatographic methods that precisely evaluate the
purity and stability of biotechnology products. This service breadth and
diversity of analytical skills and technologies positions the Company to assist
its clients from early product development through the IND and PLA stages and
commercial production.
 
     MICROBIOLOGICAL TESTING.  Microbiological testing is an essential indicator
to ensure that a drug product, whether raw material or finished product, does
not contain harmful micro-organisms. The Company has significant experience
conducting various microbial tests to identify and quantify micro-organisms that
may be present, including limulus amebocyte lysate (LAL) testing, which measures
toxic byproducts of micro-organisms, and particulate matter testing to determine
the presence of foreign matter in injectable drug products. The Company also
performs sterility testing to identify the genus and species of any
micro-organisms that are present. In addition, the Company performs tests to
determine the effectiveness of antibiotics against micro-organisms and minimum
levels of preservatives necessary in product formulations.
 
     The Company also assists clients with environmental monitoring, including
water and air systems testing using an automated biochemical system to identify
micro-organisms present and determine
 
                                       32
<PAGE>   38
 
whether such systems are within applicable microbial limits. The Company assists
clients in validating their environmental control systems to ensure compliance
with GMP regulations.
 
     BIOANALYTICAL TESTING.  The Company offers bioanalytical testing services
to support clinical trials, analyzing plasma samples to characterize the
metabolized forms of the drug and determine the rate of absorption.
Bioanalytical studies of new drugs often present challenging and complex issues,
with products being metabolized into multiple active and inactive forms, each of
which must be measured. The Company works with its clients to develop and
validate analytical methods to permit detection and measurement of the various
components to trace levels.
 
     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 spectroscopy, chromatographic analysis and
other physical chemistry techniques. Additionally, the Company uses such
information for control testing to be performed throughout development and
marketing to confirm consistent drug composition. 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.
 
     ORGANIC SYNTHESIS.  The Company develops synthesis methods for producing
experimental quantities of new compounds needed for analytical characterization,
toxicological studies, formulation development and clinical trials. Through
organic synthesis techniques, the Company can produce reference standards of the
active compound, specific impurities, degradation by-products, bioassay
reference standards or molecular analogs to permit sufficient quantities of such
compounds to be separately characterized and studied.
 
FORMULATION DEVELOPMENT SERVICES
 
     The Company provides 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 formulation expertise and
extensive analytical capabilities enable it to provide an efficient, seamless
development program, with a dedicated project team tracking the product through
all stages of formulation development. The Company provides formulation
development services to its clients during each phase of the drug development
process from new compounds and modifications of existing products, to generic
versions of branded products. The Company's formulation development projects may
support a small segment of critical development activities or may last for
several years going from early formulation development to optimized and
validated production-scale, packaged product. Currently, the Company was
providing critical development services for 48 products for submission to or
under review by the FDA.
 
     The Company's formulation development expertise spans a broad spectrum of
therapeutic areas. The Company works with clients to develop products with
desired characteristics, including dosage form, strength, release rate,
absorption properties, stability and appearance. The Company has developed
significant product and process "know-how" that enables it to more efficiently
solve the complex problems that arise in developing formulations with targeted
characteristics and has developed a range of proprietary product technologies
that allow it to better achieve desired results in product design and
development.
 
     In providing formulation services, the Company works closely with clients
to design and conduct feasibility studies to chart the potential of formulating
a drug using a combination of active drug ingredients and inert "filler"
materials called excipients. Using experimental designs, initial prototype
formulations are prepared to identify potential problems in stability,
bioavailability and manufacturing. Generally, formulation development is an
iterative process, with numerous initial formulations being modified as problems
are encountered. The Company believes its experience and expertise in
formulation
 
                                       33
<PAGE>   39
 
development, as well as certain proprietary technologies, permit it to design
efficient protocols for identifying and optimizing prototypes with the greatest
potential.
 
     Upon selection of the final product prototypes, the Company develops
protocols to scale the product batch size from development stage (hundreds or
thousands of units) to clinical scale (thousands or millions of units). During
the clinical phase the Company refines the formulation in response to clinical,
bioanalytical and stability data. The manufacturing scale-up process involves
identifying and resolving manufacturing problems to facilitate an efficient
transfer to the full-scale production equipment of the Company's clients.
Throughout the development process, the Company develops and validates the
analytical methods necessary to test the product to establish and confirm
product specifications.
 
     In addition to new drug development, the Company offers product
modification and line extension services to clients, generally for marketed
products facing patent expiration. Modifications of existing products offer the
Company's clients an opportunity to improve product characteristics, increasing
product market viability. Improved product characteristics include enhancement
of stability, absorption profiles (e.g., quick or sustained release), taste and
appearance. Product line extensions may include new dosage forms such as solids,
liquids and chewables, as well as new dosage strengths. Product modifications
and line extensions offer clients the opportunity to target new patient
subpopulations and improve patient compliance. The Company also offers
formulation services to clients seeking to develop generic products.
 
  CLINICAL SUPPLY AND NICHE MANUFACTURING
 
     The Company provides clinical trials materials for Phase I through IV
clinical trials, as well as bioequivalency studies of generic products. In the
two years ended December 31, 1995, the Company produced more than 40 million
units of more than 100 products in its clinical supply facilities. The Company
has expertise in manufacturing tablets, capsules, sachets, liquids and
suspensions, creams, gels, lotions and ointments. The Company believes that
outsourcing of clinical supply manufacturing is particularly attractive to
pharmaceutical companies that maintain large, commercial-quantity, batch
facilities, where clinical supply manufacturing would divert resources from
revenue-producing manufacturing. Similarly, pharmaceutical companies often seek
to outsource commercial manufacturing of small quantity products. In addition,
the Company provides its clients assistance in scaling up production of clinical
supply quantities to commercial quantity manufacturing, and manufactures
inventory on behalf of clients for commercial sale while client production
facilities are being built and validated.
 
     The Company's manufacturing facilities and equipment are qualified and
validated to operate under GMP regulations.
 
     The Company currently maintains a five-room manufacturing facility, which
has been operating at or near capacity. The Company is completing the
construction of four additional processing rooms scheduled to be completed in
the third quarter of 1996 and an additional ten processing rooms scheduled to be
completed in the first half of 1997. In addition to clinical supply
manufacturing, the Company is currently manufacturing one commercial product for
a client.
 
  REGULATORY AND COMPLIANCE CONSULTING
 
     The Company assists in the preparation of regulatory submissions, audits a
client's vendors and client operations, conducts seminars, provides training
courses, and advises clients on applicable regulatory requirements. The Company
also assists international clients in designing development programs for new or
existing drugs intended to be marketed in the United States. At the client's
request, the Company will either review client prepared submissions or draft
sections and assemble IND, NDA, PLA and ANDA packages and attend FDA meetings
with clients.
 
     The Company assists clients in preparation for FDA inspections and assists
them in correcting any deficiencies noted in FDA inspections. In preparation for
an FDA inspection, the Company's regulatory affairs specialists conduct mock
inspections to anticipate FDA observations and advise clients of
 
                                       34
<PAGE>   40
 
appropriate remedial actions. The Company also audits manufacturers of active
and excipient ingredients used in the drug product, as well as packaging
components, on behalf of clients to ensure that the manufacturers' facilities
are in compliance with GMP regulations. Such audits generally include review of
the vendor drug master files, analysis of standard operating procedures, review
of production records, and observation of operations to ensure SOPs are being
followed. Audit reports include recommendations to address any deficiencies. The
Company also advises clients on validation issues concerning their systems and
processes and audits client facilities to assist them in validating their
processes, cleaning, water and air handling systems.
 
     The Company leverages its in-house laboratory training programs by
providing training to clients' employees. Training programs scheduled in 1996
include GMP training, pharmaceutical testing techniques, metrology and quality
assurance topics. In addition, the Company organizes and conducts seminars
worldwide on a number of topical industry issues. In 1996, the Company has
conducted six seminars, with an additional six seminars scheduled for the
remainder of the year, covering stability issues, validation requirements in
analytical laboratories, cleaning validation and microbiology.
 
  PHASE I/BIOEQUIVALENCY STUDIES
 
     The Company is scheduled to open a 48-bed clinical trial facility at its
Research Triangle Park location in the third quarter of 1996. The clinical trial
unit will be located in the same facility as the Company's bioanalytical
laboratory and will permit time-sensitive and rapid-response analysis in
clinical trials. The clinical trial unit is initially intended for use in
bioequivalency studies of generic drug products and is intended to be available
for Phase I clinical trials by the first quarter of 1997. When opportunities
arise and the economics are attractive, the Company intends to expand its
service offerings into other phases of clinical trials in the future to assist
its clients in moving product development seamlessly between clinical and
nonclinical activities, providing consistency, continuity and quality throughout
the development process and avoiding fragmentation of the process.
 
INTERNAL DRUG AND TECHNOLOGY DEVELOPMENT
 
     The Company intends to dedicate a significant proportion of its technical
resources and operating capacity to internal drug and technology development
with the objective of licensing marketing rights to third parties. The Company
does not intend to independently commercialize products developed internally or
otherwise directly compete with its clients in the marketing or distribution of
products and, accordingly, believes that its internal development efforts are
complementary to its clients' development needs. The Company's internal product
and technology development program has resulted in 12 generic product
applications filed with the FDA. Applications for six of those products have
been approved in its clients' names, of which four products are currently
licensed and two have been sold. The Company's current development pipeline
consists of ten unlicensed products in multiple dosage forms. The internal
development program has also resulted in ten patents covering drug technology
and four pending patents.
 
     Since 1993, the Company has spent over $7.8 million on research and
development, all related to its internal drug and technology development
program. Because of the significant time required for development and approval
of pharmaceutical products, the Company has only recently begun to recognize
significant license revenue from its internal drug and technology development
efforts. The Company anticipates that licensing revenue, including royalties and
milestone payments, from internal drug and technology development will represent
a larger proportion of its revenue, although there can be no assurance that
internal development projects will yield products that will be approved by the
appropriate regulatory authorities or will be attractive to potential clients.
In 1996, the FDA approved a generic product licensed by the Company to a client
which is the first approved generic version of a branded product which has over
$100 million in sales in 1995. The Company expects to receive royalties on this
product beginning in the fourth quarter of 1996, although there can be no
assurance that such product will be marketed. Although there is a risk that any
particular development project may not
 
                                       35
<PAGE>   41
 
produce revenues, the Company believes that the profit margins from successful
drug and technology development projects potentially exceed the margins on
standard fee-for-service engagements.
 
     INTERNAL DRUG DEVELOPMENT
 
     In 1993, the Company began allocating a significant portion of its
technical resources and operating capacity to internal development of generic
drugs. The U.S. generic drug market has expanded sales from $3.5 billion in 1990
to $6.4 billion in 1994. Generic drugs accounted for 46% of prescriptions
dispensed in the U.S. in 1994. The Company anticipates that the growth in the
generic drug market will continue as managed care organizations pursue policies
favoring generic substitution and as patents on many high revenue products
expire over the next several years.
 
     The Company's research and development committee, composed of
representatives from the formulations development, marketing and legal
departments, identifies potential generic drug development candidates for the
program. The committee selects development candidates after reviewing market
size and trends, current therapies and potential advances, patent and
formulation issues. In certain instances, the committee has also invited outside
consultants and medical panels to review selections.
 
     The first group of products in the Company's internal product development
program involved generic versions of certain hormone products. In 1994, as part
of its internal development program, the Company organized Endeavor with certain
financial investors and an affiliate of Berlex Laboratories, Inc. to continue
the development of certain generic hormone products then under development by
AAI. The Company assigned its rights to such products to Endeavor in return for
approximately 47% of Endeavor's equity during a private placement of Endeavor
stock, and the Company entered into a development contract with Endeavor to
continue product development and clinical supply manufacture. AAI currently owns
approximately 38% of the fully diluted common equity of Endeavor, and the
Company's net sales to Endeavor were approximately $2.0 million, $3.5 million
and $1.6 million in 1994, 1995 and the three months ended March 31, 1996,
respectively. Endeavor has submitted one ANDA to the FDA, and an additional
product is undergoing a bioequivalency study. See "Certain
Transactions -- Transactions Involving Management".
 
     Five of the Company's internal development projects were sold in 1995 to
Aesgen, a company organized by the Company with an affiliate of Mayo Clinic,
MOVA Pharmaceutical Corporation and certain financial investors, to focus on the
development of certain generic products. Aesgen entered into a development
agreement with the Company to continue development of the products initially
sold to Aesgen and other promising candidates identified by Aesgen. AAI
recognized net sales to Aesgen of $5.6 million and $688,000 in 1995 and for the
three months ended March 31, 1996, respectively. AAI continues to hold a $1.6
million non-voting, non-convertible preferred stock investment in Aesgen. See
"Certain Transactions -- Transactions Involving Management".
 
     In addition to its development work for Endeavor and Aesgen, the Company
has continued its internal development of products to be licensed to third
parties that have marketing and distribution capabilities. The Company has
entered into four license agreements of products which are currently in
development. The terms of the license agreements vary as to amounts of initial
and milestone payments, as well as methods and extent of revenue participation.
In 1996, the Company has continued to increase the number of internal projects
and currently has ten products, in addition to the already licensed products, at
various stages of development. While the Company anticipates that most of its
product license agreements will provide that prospective clients will sponsor
the approved ANDA, the Company has made two ANDA submissions for internally
developed products in its own name which are currently under review at the FDA.
 
     Continuing to leverage its development capabilities, the Company is moving
beyond generic drug development and has also begun reviewing new compounds that
are chemically similar to currently marketed products with proven therapeutic
and safety profiles, and that offer improved characteristics over the marketed
product. Such improved characteristics would include enhanced therapeutic
indices, reduced side effects, improved bioavailability and improved
pharmacokinetics. Since considerable
 
                                       36
<PAGE>   42
 
toxicity data already exists for the marketed product, the Company believes that
new compound modifications or pro-drugs generally could be developed with less
risk of failure and in a shorter time frame than new chemical entity
development. The Company believes that virtual and limited resource drug
companies provide opportunities to enter into collaborative ventures to identify
and develop this type of compound. The Company has completed preliminary
analysis of five such compounds and has entered discussions with two
pharmaceutical companies to enter into shared-risk development projects with
each company, although there can be no assurance that the Company will enter
into shared-risk agreements for these products.
 
     TECHNOLOGY DEVELOPMENT PROGRAM
 
     As an adjunct to the internal development program, the Company has sought
to protect certain intellectual property it has developed relative to the drug
development process. The Company has established a patent committee which meets
quarterly to review employee-generated submissions of possible patentable
subject matter. The patent committee reviews the novelty and usefulness of the
submission and, with input from the marketing department as to commercial
viability, determines to either pursue a patent application or designate the
submission as a trade secret.
 
     The Company's technology development program has yielded ten issued patents
and has four pending applications. For example, the Company's patented
Pro-Sorb(TM) formulation technology has been shown to facilitate the oral
absorption of a number of non-steroidal anti-inflammatory drugs or NSAIDs, such
as ibuprofen, to reduce gastric irritation and speed the onset of therapeutic
activity. In addition, the Company has patented a novel oral delivery system for
certain biotechnology compounds that may currently be administered only by
injection.
 
     The Company has one licensing agreement for a patented technology for the
manufacture of low-dose products which are typically difficult to uniformly
blend and an additional licensing arrangement for its patented chewable
formulations to mask the otherwise bitter taste of certain ulcer drugs. The
Company is seeking licensing partners for its other recently developed
technologies.
 
ENDEAVOR
 
     The Company owns shares of convertible preferred stock of Endeavor,
representing approximately 38% of the fully diluted common equity. AAI also
provides development services to Endeavor at terms that the Company believes are
no less favorable than terms that would be obtained from an unrelated third
party.
 
     As of the date of this Prospectus, Endeavor had submitted an ANDA
application for one product in multiple dosage strengths, although there can be
no assurance that such ANDA application will be approved. In addition, Endeavor
is scheduled to submit an ANDA application for an additional generic hormone
product in multiple dosage forms after completing bioequivalency studies
scheduled to conclude in the second half of 1996. Endeavor does not market any
products and has not received approval of any product. Endeavor's revenues are
dependent upon approval of its products. The Company believes that Endeavor
intends to market its products through licensing to third parties.
 
     In addition to his duties at AAI, Frederick D. Sancilio, President of the
Company, serves as a senior management employee and director of Endeavor. Dr.
Sancilio does not maintain an office or have day-to-day responsibilities at
Endeavor and devotes a substantial majority of his time to the management of the
Company. In addition, three other executive officers of AAI serve on Endeavor's
nine-member board of directors. See "Certain Transactions -- Transactions
Involving Management".
 
INFORMATION TECHNOLOGY
 
     The Company has made significant investments in information technology. The
Company's LTS system tracks laboratory workflow and enables the Company to
effectively monitor and plan work through the Company's laboratories. The system
monitors the progress of a client's project, records time expended by laboratory
personnel, tracks sample locations and controls document revisions. The
 
                                       37
<PAGE>   43
 
Company's customized data management system connects approximately 125
analytical instruments with multiple software architectures permitting automated
data capture. In addition, the Company is currently conducting a pilot test of a
system allowing certain domestic and international clients secured access to
review in-progress laboratory data. This system will allow a client to
efficiently monitor the immediate status of the project and make changes to the
scope and format of its project. The Company intends to introduce this system to
a broader client group in 1997.
 
     The Company believes that superior information technology will enable it to
expedite the development process by designing innovative services for individual
client needs, providing project execution, monitoring and control capabilities
that exceed a client's internal capabilities, streamlining and enhancing data
presentation to the FDA and enhancing its own internal operational productivity
while maintaining its quality. The Company is committed to taking a leadership
position in the competitive use of information to enhance the pharmaceutical
development process. The Company has begun to develop a database of client
information integrating data, documents, electronic messages, and reference
services. The Company intends to make this database available with secured
on-line access through the Internet which would permit client access to data on
its projects at any location worldwide and facilitate FDA on-line access to the
extensive data necessary to support the chemistry, manufacturing and control
section of a regulatory application. The Company also believes that this service
will allow clients to avoid delays currently incurred in FDA staff audits of
paper-copy data stored at the Company's or clients' facilities.
 
CLIENTS
 
     Over the past five years, the Company has provided services to 24 of the
top 25 pharmaceutical companies in the world as ranked by 1994 research and
development spending. During 1995, the Company provided services under
approximately 850 contracts to approximately 220 clients, including some of the
largest U.S., European and Japanese drug companies.
 
     The Company believes that 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 experience such concentration in the future.
During 1995, three of the Company's clients accounted for 10% or more
(approximately 16.0%, 11.2% and 10.2% respectively) of the Company's net sales.
During the first three months of 1996, one client accounted for 10% or more
(approximately 15.8%) of the Company's net sales. Endeavor and Aesgen accounted
for approximately 10.2% and 16.0%, respectively, of net sales in 1995 and 15.8%
and 6.9% of net sales for the first three months of 1996. Although AAI 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.
See "Risk Factors -- Dependence on Certain Industries and Clients".
 
MARKETING AND BUSINESS DEVELOPMENT
 
     Since its inception, the Company has taken a customer-focused approach in
marketing its services, often placing the Company's technical personnel with its
clients' development teams to participate in planning meetings for the
development of a product. The Company assigns sales and technical personnel as
contacts for its larger clients, understanding that technical personnel may be
better able to identify the full scope of the client's needs and suggest
innovative approaches before the client formally develops the parameters of an
anticipated project. Generally, the Company also hosts more than ten technical
seminars per year for the pharmaceutical and biotechnology industries addressing
a variety of formulation development issues, stability testing and other topics.
 
     The Company employs 11 sales personnel and 12 customer service
representatives, many with a technical backgrounds, with offices in Wilmington
and Research Triangle Park, North Carolina; San Francisco, California; Elmwood
Park, New Jersey; Boston, Massachusetts; Chicago, Illinois and San Juan, Puerto
Rico. The Company also maintains sales offices in Copenhagen, London and Milan
to better serve and develop its European client base.
 
                                       38
<PAGE>   44
 
CONTRACTUAL ARRANGEMENTS
 
     The Company's fee-for-service contracts are typically evidenced by signed
service estimates establishing an estimated fee for identified services. During
the Company's performance of a project, 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 notice of 30 days or less, although certain major formulation
development and manufacturing agreements are not unilaterally terminable by the
client. Although the contracts typically permit payment of certain fees for
winding down a project, 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 -- Dependence on Certain Industries and Clients".
 
BACKLOG
 
     Backlog consists of anticipated net sales from signed service estimates and
other fee-for-service contracts that have not been completed and provide for a
readily ascertainable price. Once contracted work begins, net sales are
recognized as the service is performed on the percentage of completion basis. In
certain cases, the Company begins work for a client before a contract is signed.
Accordingly, backlog does not include anticipated net sales for which the
Company has begun work but for which the Company does not have a signed service
estimate, or for any variable-priced contracts. In addition, during the course
of a project the client may substantially adjust the requested scope of services
and corresponding adjustments are made to the price of services under the
contract.
 
     The Company believes that its backlog as of any date is not a meaningful
predictor of future results because backlog can be affected by a number of
factors, including variable size and duration of contracts and adjustments in
the scope of a contracted project as interim results become available.
Additionally, contracts generally are subject to termination by clients upon 30
days notice or less. Moreover, the scope of a contract can change over the
course of a project. At December 31, 1995, backlog was approximately $19.7
million, as compared to $12.7 million at December 31, 1994.
 
COMPETITION
 
     The Company competes against the in-house research, quality control and
other support service departments of pharmaceutical companies, as well as
university research labs. In addition, the Company believes that although there
are numerous competitors in its industry, there are few competitors that offer a
broad array of services that it provides. The largest competitor offering these
services is Corning Lab Services, Inc., a subsidiary of Corning, Inc. Certain of
the Company's competitors, including Corning Lab Services, Inc., may have
significantly greater resources than the Company. Competitive conditions for
service areas vary.
 
     Competitive factors include reliability, turn-around time, reputation for
innovative and quality science, capacity to perform numerous required services,
financial viability and price. The Company believes that it competes favorably
in these areas.
 
POTENTIAL LIABILITY AND INSURANCE
 
     The Company maintains product liability and professional errors and
omissions liability insurance, providing $5 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
 
                                       39
<PAGE>   45
 
with clients and the 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, AAI 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. See "Risk Factors  -- Potential Liability and Risks
of Operations".
 
GOVERNMENT REGULATION
 
     The services performed by the Company are subject to various regulatory
requirements designed to ensure the quality and integrity of pharmaceutical
products, primarily under the Federal Food, Drug and Cosmetic Act and associated
GMP regulations which are administered by the FDA in accordance with current
industry standards. These regulations apply to all phases of drug manufacture,
testing and record keeping, including personnel, facilities, equipment, controls
of materials, processes and laboratories, packaging, labelling and distribution.
Noncompliance with GMP by the Company in a project could result in
disqualification of data collected by the Company in the project. Material
violation of GMP requirements could result in additional regulatory sanctions,
and in severe cases could result in a mandated closing of the Company's
facilities which would materially and adversely affect the Company's business.
 
     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. Certain of the
Company's development and testing activities are subject to the Controlled
Substances Act, administered by the Drug Enforcement Agency (the "DEA"), which
regulates strictly all narcotic and habit-forming substances. The Company
maintains separate, 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.
 
     The Company's activities involve the controlled use of hazardous materials
and chemicals. The Company is subject to federal, state and local laws and
regulations governing the use, storage, handling and disposal of such materials
and certain waste products. Although the Company believes that its safety
procedures for handling and disposing of such materials comply with the
standards prescribed by federal, state and local laws and regulations, 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 materially adversely affect the
financial condition of the Company.
 
EMPLOYEES
 
     At May 31, 1996, the Company had 463 full-time equivalent employees, of
which 34 hold Ph.D. degrees and approximately 50 others who hold masters or
other post-graduate degrees. The Company believes that its relations with its
employees are good. None of the Company's employees is 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 such skilled personnel is high. The Company believes that
its employee benefit plans, including its health benefit, profit-sharing and
employee stock option plans, enhance employee morale, professional commitment
and work productivity and provide an incentive for employees to remain with the
Company. In addition, the Company operates a 65-child, employee day-care
facility at its Wilmington, North Carolina campus as a benefit to its employees
and is expanding this facility. While the Company has not experienced any
significant
 
                                       40
<PAGE>   46
 
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 protecting the
Company's proprietary information, as well as client-confidential material. New
technical employees are generally required to sign non-competition agreements,
prohibiting the employee from engaging in activities in competition with the
Company for a period of one year after termination of employment.
 
FACILITIES
 
     The Company's principal executive offices are located in Wilmington, North
Carolina, in a 17,000-square foot leased facility. The Company's primary
facilities are located in Wilmington and Research Triangle Park, North Carolina
constituting approximately 150,000 square feet of operational and administrative
space. The Company maintains sales offices in San Francisco, California; Elmwood
Park, New Jersey; Boston, Massachusetts; Chicago, Illinois; San Juan, Puerto
Rico and European sales offices in Copenhagen, Denmark, London, England, and
Milan, Italy. The Company believes that its facilities are adequate for the
Company's operations and that suitable additional space will be available when
needed.
 
     The Company is completing the construction of a 48-bed clinical trial
facility at its Research Triangle Park facility to conduct Phase I and
bioequivalency studies. The clinical facility is scheduled to open in the third
quarter of 1996. In addition, the Company is expanding its clinical supply and
niche manufacturing capacity more than threefold with additional processing
rooms scheduled to be completed throughout the second half of 1996 and the first
half of 1997.

EMPLOYMENT AND COMPENSATION AGREEMENT
 
     On November 17, 1995 (the "Signing Date"), the Company and Frederick D.
Sancilio entered into an employment agreement (the "Employment Agreement") to
secure Dr. Sancilio's services as Chairman of the Board and President of the
Company. The employment agreement has an initial three-year term which is
automatically extended for an additional one-year period on each anniversary of
the Signing Date unless either party gives the other notice prior to the
anniversary date of its intention not to extend the term of the Employment
Agreement. Under the Employment Agreement, Dr. Sancilio will serve as the
Company's Chairman of the Board, President and chief executive officer, and the
Company is required to use its best efforts to cause Dr. Sancilio to be
re-elected to the Company's Board of Directors and to the boards of directors of
affiliates of the Company on which boards of directors Dr. Sancilio was serving
on the Signing Date and to be elected a director of any majority-owned
subsidiary of the Company acquired after the Signing Date.
 
                                       44
<PAGE>   50
 
     The Employment Agreement provides that Dr. Sancilio will receive an annual
salary of $250,000, which amount may be increased by the Board of Directors and
once increased may not be reduced. The Employment Agreement provides that Dr.
Sancilio will be eligible to receive bonus compensation of up to 50% of his
annual salary if the Company attains certain performance objectives set jointly
by the Board of Directors and Dr. Sancilio. In addition, Dr. Sancilio will be
eligible to participate in employee benefit plans made available generally to
the Company's executive officers and any other Company compensation or incentive
plans of a long or short-term nature and to receive other perquisites not to
exceed, in the aggregate, $10,000 per year.
 
     Under the Employment Agreement, the Company can terminate Dr. Sancilio's
employment at any time, with or without cause, as defined in the Employment
Agreement. In the event that the Company terminates Dr. Sancilio's employment
without cause or in the event that Dr. Sancilio terminates his employment within
90 days of an event of constructive discharge (defined in the agreement to
include, among other things, the removal of Dr. Sancilio from, or the failure of
Dr. Sancilio to be elected to, the positions of Chairman of the Board or
President, a reduction in Dr. Sancilio's responsibilities or relocation of the
Company's principal executive offices by more than 30 miles from its current
location), Dr. Sancilio would be entitled to receive payments aggregating three
times his then current annual salary to be paid in monthly installments over two
years, during which time Dr. Sancilio would continue to receive medical and life
insurance benefits. The agreement requires Dr. Sancilio to refrain from certain
activities in competition with the Company for a period of two years after the
termination of his employment for any reason.
 
     The Employment Agreement also provides Dr. Sancilio with the right to
require the Company to purchase a portion of the Common Stock owned by him upon
the termination of his employment in certain circumstances, which right will
expire upon completion of this Offering. The Employment Agreement also obligates
the Company to use its best efforts to cause Endeavor to employ Dr. Sancilio as
a senior management employee at an annual salary of at least $100,000 with bonus
compensation of up to 50% of annual salary to be paid if performance targets are
attained and greater amounts if targets are exceeded. Endeavor has employed Dr.
Sancilio on such terms. See "Certain Transactions -- Transactions with
Management".
 
     On November 20, 1995, the Company agreed to a cash bonus plan for Mr.
Colonnese pursuant to which he would receive a cash bonus of $50,000 upon the
closing of an initial public offering of the Common Stock and an additional
$50,000 one year later. In addition, in the event that the trading price per
share of the Common Stock exceeds $12.525 for 90 consecutive days, Mr. Colonnese
shall receive a $50,000 bonus and an additional $50,000 bonus one year
thereafter.
 
STOCK OPTION AND RESTRICTED STOCK AWARD PLANS
 
     Under the Company's 1995 Restricted Stock Award Plan (the "Restricted Stock
Plan") and the 1995 Stock Option Plan (the "1995 Option Plan") and the 1996
Stock Option Plan (the "1996 Option Plan"; collectively with the 1995 Option
Plan, the "Option Plans"), the Company is authorized to award up to 105,453
restricted shares of Class B Common Stock and options to purchase up to 738,165
shares of Class B Common Stock. Upon completion of this Offering all outstanding
shares of Class B Common Stock issued under the Restricted Stock Plan will be
converted into one share of Common Stock and each option to purchase one share
of Class B Common Stock will be converted into an option to purchase one share
of Common Stock at the same price per share. The following summary descriptions
of the principal terms of the Restricted Stock Plan and Option Plans do not
purport to be complete and are qualified in their entirety by the full text of
the Restricted Stock Plan and Option Plans, which have been filed as an exhibit
to the Registration Statement of which this Prospectus is a part.
 
  RESTRICTED STOCK PLAN
 
     The purpose of the Restricted Stock Plan is to promote the growth and
profitability of the Company by increasing the personal participation of certain
employees in the financial performance of the
 
                                       45
<PAGE>   51
 
Company, to compensate such employees for their contributions to the success of
the Company and to assure the continued participation of such employees in the
growth of the Company through the grant of restricted stock awards.
 
     The Restricted Stock Plan is administered by a committee (the "Committee")
composed solely of members of the Board of Directors who are both "disinterested
persons" (as defined in Rule 16b-3 promulgated under the Securities Exchange Act
of 1934, as amended) and "outside directors" (as defined in Section 162(m) of
the Internal Revenue Code of 1986, as amended, and the regulations thereunder).
The Committee has the authority to interpret the terms and provisions of, and
adopt, amend and rescind general and special rules relating to, the Restricted
Stock Plan.
 
     The Restricted Stock Plan permits the award of shares of Class B Common
Stock to long-term employees of the Company and other key employees as selected
by the Committee. Awards of shares under the Restricted Stock Plan vest over
time, and in the event of termination of a participant's employment with the
Company other than as a result of death, disability or retirement all unvested
shares are forfeited to the Company. Prior to the completion of this Offering
such shares would vest five years after the date of the award. However, pursuant
to the Restricted Stock Plan, upon completion of this Offering, 50% of the
shares awarded under the Restricted Stock Plan will vest on the first
anniversary of the date of completion of this Offering and the remaining shares
will vest on the second anniversary. Unvested shares will vest immediately upon
completion of certain transactions involving a change in control of the Company
or a sale by the Company of all or substantially all of its assets. Shares that
have not vested may not be transferred other than pursuant to certain domestic
relations orders.
 
     All 105,453 shares available under the Restricted Stock Plan have been
awarded to 120 employees, including all employees of the Company who had been
with the Company for six years or more and had maintained satisfactory job
performance levels. Any shares forfeited by participants under the Restricted
Stock Plan are available for future awards. No director or executive officer of
the Company has been granted shares of Class B Common Stock under the Restricted
Stock Plan.
 
  OPTION PLANS
 
     The purpose of the Option Plans is to promote the growth and profitability
of the Company and its subsidiaries by increasing the personal participation of
officers and key employees in the financial performance of the Company. The
Option Plans are administered by the Committee. The Committee has the authority
to interpret the terms and provisions of, and adopt, amend and rescind general
and special rules relating to the administration of, the Option Plans and to
make all other determinations necessary and advisable for the administration of
the Option Plans. All of the Company's employees are eligible to receive stock
options to purchase shares of Class B Common Stock ("Options") pursuant to the
Option Plans.
 
     Awards of Options may be made to officers and other key employees of the
Company or its subsidiaries ("Optionees"). The Option Plans permit awards of
Options intended to qualify as incentive stock options under Section 422 of the
Internal Revenue Code and nonqualified options. The Committee is authorized to
establish the exercise price of Options, although the per share exercise price
for options intended to qualify as incentive stock options may not be less than
100% of the fair market value of a share of Class B Common Stock on the date of
grant (110% for certain 10% stockholders). The exercise price per share of any
option awarded under the Option Plans may not be less than 100% of the fair
market value of a share of Class B Common Stock on the date of grant of the
Option (the "Grant Date") unless all members of the Compensation Committee
agree, and in no event may it be less than 75% of the fair market value on the
Grant Date. In addition, pursuant to an agreement among the Company and its
stockholders entered into in connection with the issuance of the Preferred Stock
the exercise price for options granted under the 1996 Option Plan may be no less
than the per Common Share equivalent price paid by the purchasers of the
Preferred Stock in November 1995 ($8.35). The Committee is authorized
 
                                       46
<PAGE>   52
 
to set the term of the options, which may be no longer than 10 years (5 years
for certain options intended to qualify as incentive stock options).
 
     Options awarded under the Option Plans become exercisable with respect to
25% of the total shares under the option six months after the grant date, 50% of
the total shares 18 months after the grant date, 75% of the total shares 30
months after the grant date and 100% of the total shares 42 months after the
grant date. The Options become immediately exercisable upon completion of
certain transactions involving a change in control of the Company or a sale by
the Company of all or substantially all of its assets. Unexercised options
expire upon termination of the Optionee's employment, other than as a result of
death, disability or retirement, in which cases Options may be exercised for a
specified period after termination of employment. Options may not be transferred
other than by will or the laws of descent and distribution or pursuant to
certain qualified domestic relations orders.
 
     Of the 242,538 shares of Class B Common Stock authorized under the 1995
Option Plan, options to purchase 241,700 shares had been issued to 12 employees
and were outstanding on May 1, 1996. The exercise price of such options is $8.35
per share. Under the terms of the plan, the Company will purchase from Dr.
Sancilio and Mr. Waters, upon the exercise of Options, a number of shares of
Class B Common Stock (or Common Stock following mandatory conversion of Class B
Common Stock) equal to the number of shares subject to the exercised Options, at
an exercise price equal to the exercise price of such Options (or Common Stock
following the mandatory conversion of Class B Common Stock) to provide the
shares for issuance.
 
     Of the 495,627 shares authorized under the 1996 Option Plan, Options to
purchase 208,744 shares had been issued to 83 employees and were outstanding on
May 1, 1996. The exercise price of such Options is $8.35 per share. The 1996
Option Plan permits the award of options to purchase no more than 210,876 shares
prior to January 1, 1997 and no person may be awarded Options to purchase more
than 189,750 shares of Class B Common Stock under the 1995 Option Plan or more
than 253,000 shares of Class B Common Stock under the 1996 Option Plan. Options
for the following numbers of shares have been granted under the 1995 Option Plan
to the following Named Executive Officers of the Company at an exercise price
per share equal to $8.35: Mr. Colonnese, 88,093 shares, Mr. Swarbrick, 79,871
shares and all executive officers as a group, 167,964 shares. Options for the
following numbers of shares have been granted under the 1996 Option Plan to the
following Named Executive Officers of the Company at an exercise price per share
equal to $8.35: Mr. Hunicutt, 101,376 shares, Mr. Underwood, 7,680 shares and
all executive officers as a group, 124,416 shares.
 
     CERTAIN FEDERAL INCOME TAX CONSEQUENCES.  The following discussion is a
brief summary of the principal United States federal income tax consequences
under current federal income tax laws relating to Options awarded under the
Stock Option Plans. This summary is not intended to be exhaustive and, among
other things, does not describe state, local or foreign income and other tax
consequences.
 
     An Optionee will not recognize any taxable income upon the grant of a
nonqualified option and the Company will not be entitled to a tax deduction with
respect to such grant. Upon exercise of a nonqualified option, the excess of the
fair market value of the shares on the exercise date over the exercise price
will be taxable as compensation income to the Optionee. Subject to the Optionee
including such excess amount in income or the Company satisfying applicable
reporting requirements, the Company should be entitled to a tax deduction in the
amount of such compensation income. The Optionee's tax basis for the shares
received pursuant to such exercise will equal the sum of the compensation income
recognized and the exercise price.
 
     In the event of a sale of shares received upon the exercise of a
nonqualified option, any appreciation or depreciation after the exercise date
generally will be taxed as capital gain or loss and will be long-term gain or
loss if the holding period for such stock was more than one year.
 
     Generally, an Optionee should not recognize taxable income at the time of
grant or exercise of an incentive stock option and the Company should not be
entitled to a tax deduction with respect to such
 
                                       47
<PAGE>   53
 
grant or exercise. The exercise of an incentive stock option generally will give
rise to an item of tax preference that may result in alternative minimum tax
liability for the Optionee.
 
     A sale or other disposition by an Optionee of shares acquired upon the
exercise of an incentive stock option more than one year after the transfer of
the shares to such Optionee and more than two years after the date of grant of
the incentive stock option should result in any difference between the net sale
proceeds and the exercise price being treated as long-term capital gain or loss
to the Optionee with no deduction being allowed to the Company. Upon a sale or
other disposition of shares acquired upon the exercise of an incentive stock
option within one year after the transfer of the shares to the Optionee or
within two years after the date of grant of the incentive stock option
(including the delivery of such shares in payment of the exercise price of
another incentive stock option within such period), any excess of (a) the lesser
of (i) the fair market value of the shares at the time of exercise of the Option
and (ii) the amount realized on such disqualifying sale or other disposition of
the shares over (b) the exercise price of such shares, should constitute
ordinary income to the Optionee and the Company should be entitled to a
deduction in the amount of such income. The excess, if any, of the amount
realized on a disqualifying sale over the fair market value of the shares at the
time of the exercise of the Option generally will constitute short-term or
long-term capital gain and will not be deductible by the Company. Special rules
may apply to Optionees who are subject to Section 16 of the Securities and
Exchange Act of 1934, as amended.
 
     Under certain circumstances the accelerated vesting or exercise of Options
in connection with a change of control of the Company might be deemed an "excess
parachute payment" for purposes of the golden parachute tax provisions of
section 280G of the Internal Revenue Code. To the extent it is so considered,
the Optionee may be subject to a 20% excise tax and the Company may be denied a
tax deduction.
 
     SECTION 162(M).  Section 162(m) of the Internal Revenue Code generally
disallows a federal income tax deduction to any publicly held corporation for
compensation paid in excess of $1 million in any taxable year to the chief
executive officer or any of the four other most highly compensated executive
officers who are employed by the Company on the last day of the taxable year.
Compensation attributable to Options granted under the Option Plans should not
be subject to such deduction limitations.
 
                              CERTAIN TRANSACTIONS
 
TRANSACTIONS INVOLVING MANAGEMENT
 
     The Company leases its headquarters facility from 5051 New Centre Drive,
LLC ("New Centre"), an entity in which each of Mr. Waters and Dr. Sancilio owns
a one-third interest. Pursuant to the lease agreement between the Company and
New Centre, the Company pays rent at an annual base rate of $12.50 per square
foot of space leased, subject for adjustment for increases in the landlord's
expense in maintenance and insurance of the facility. The effective rate per
square foot was increased to the current rate of $13.30 commencing in June 1995
to reflect such increased expenses. Under the agreement, the Company may lease
portions of the entire facility as needed and upon agreement of New Centre. At
March 31, 1996, the Company leased approximately 17,000 square feet of space
under the agreement. The initial term of the lease agreement expires in March
1999, but the agreement will extend for successive one-year periods unless
either party provides the other, at least 90 days prior to the scheduled
expiration of the agreement, notice of its intent not to renew the lease. The
lease rate for any renewal term is to be set by mutual agreement of the parties.
 
     Approximately 38% of the capital stock of Endeavor on a fully diluted basis
is held by the Company and certain directors of the Company serve as directors
and officers of Endeavor. Pursuant to an agreement among the Endeavor
stockholders, the Company has the right to designate four of the nine members of
the Endeavor board of directors, although in the event that AAI fails to achieve
certain development milestones it may designate only two of the directors. AAI
realized $3.5 million and $1.6 million in net sales to Endeavor in 1995 and the
first three months of 1996, respectively. The Company made a $1.5 million
revolving credit facility available to Endeavor at a 10% annual interest rate
 
                                       48
<PAGE>   54
 
that was repaid in the fourth quarter of 1995 and was terminated. In 1995, the
maximum amount outstanding under the credit facility was approximately $1.1
million.
 
     The Company provides product development services pursuant to an agreement
with Endeavor in connection with hormone pharmaceutical products that Endeavor
is developing. The Company has agreed to manufacture products developed by
Endeavor at the Company's manufacturing facility located at 1726 North 23rd
Street, Wilmington, North Carolina, until Endeavor achieves a specified
development milestone. The Company currently anticipates that the milestone
triggering the commencement of such option will occur in the third quarter of
1996. The Company has agreed that at such time, it will grant to Endeavor a
lease/purchase option to either lease for 15 years or purchase the portion of
such facility intended for use by AAI in manufacturing Endeavor's products. Upon
achievement of the milestone by Endeavor, the Company will also sell to Endeavor
the equipment and inventory of raw materials, assign to Endeavor its raw
materials supply agreements relating to Endeavor's products and make available
certain personnel to Endeavor so that Endeavor can assume manufacturing
operations. Upon exercise of either the option to lease or the option to
purchase, Endeavor is required to pay an exercise price of $2 million to the
Company in addition to lease payments or a purchase price based on the fair
market value of the facility. If Endeavor has exercised the option to lease but
does not subsequently exercise the option to purchase and does not achieve
certain development milestones by a specified date, AAI must repay the option
exercise price to Endeavor. The facility subject to the option is currently used
by the Company for clinical supply and niche manufacturing operations. The
Company is presently expanding its clinical supply and niche manufacturing
facilities which could be used to manufacture Endeavor's products currently
under development or Endeavor exercises its option to manufacture such product
itself or for other client work. The Company has also agreed to permit Endeavor
under certain circumstances the first right to purchase additional proprietary
hormone pharmaceutical products developed by AAI at a price equal to the amount
of development work expended by AAI at its standard hourly rates and
out-of-pocket expenses and AAI would continue the development work with respect
to such product under the agreement with Endeavor.
 
     In addition to his duties at AAI, Dr. Sancilio is employed by Endeavor as a
senior management employee. Pursuant to his employment agreement with Endeavor,
Dr. Sancilio is to be based at AAI's principal executive offices and does not
have day-to-day responsibilities in the operation of Endeavor and is assigned
responsibilities from time to time by Endeavor's board of directors. Dr.
Sancilio receives an annual salary of $100,000 and is eligible for bonus
compensation of up to 50% of salary. Dr. Sancilio's employment agreement with
Endeavor has an initial two-year term expiring on November 17, 1997 and renews
for successive one-year periods unless either party elects not to renew the
agreement. Dr. Sancilio devotes the substantial majority of his time on the
management of AAI.
 
     In addition, the Company provided management and administrative services to
Endeavor at an annual fee of $120,000 through April 1996 when this agreement was
terminated by Endeavor. The Company believes that the terms of each of the
foregoing agreements are no less favorable than terms that would be obtained in
an agreement with an unrelated third party.
 
     The Company provides product development services to Aesgen, which develops
generic pharmaceutical products. Approximately 30% of Aesgen's outstanding
common stock is held by a corporation owned by holders of substantially all of
AAI's currently outstanding shares of capital stock. In addition, Mr. Waters and
Dr. Sancilio serve on the ten-member board of directors of Aesgen. AAI realized
$5.6 million and $688,000 in net sales to Aesgen in 1995 and the first three
months of 1996, respectively. AAI has the right under its development agreement
with Aesgen to provide certain product development and support services to
Aesgen with respect to the four generic drugs with multiple dosage forms
currently being developed by Aesgen, provided that AAI's fees for such services
are comparable to those of a reasonably comparable firm. In addition, under such
development agreement, the Company has agreed, absent certain circumstances, not
to develop for its own account or for any other person, any formulation of a
product intended to be therapeutically equivalent to the same reference product
for any of the products currently under development by Aesgen and any additional
drugs that AAI agrees to develop for Aesgen under the development agreement. The
Company believes that the terms of such
 
                                       49
<PAGE>   55
 
agreement are no less favorable than terms that would be obtained in a
transaction with an unrelated third party.
 
     While incorporated in July 1994, Aesgen, Inc. ("Aesgen") was formally
organized and funded in April 1995 via issuance of approximately $11 million of
nonconvertible, non-voting, mandatorily redeemable, preferred stock. As the
Company did not intend to hold an equity interest, the Company entered a series
of related transactions commencing in December 1995, the Company transferred to
a corporation ("Aesgen Holding") owned by the holders of substantially all of
the currently outstanding capital stock of the Company, approximately 30% of the
outstanding Aesgen common stock in return for $50,000 (the amount paid by AAI
for such shares) and Aesgen Holding's assumption of and AAI's release from an
obligation to invest an additional $1.2 million in Aesgen. The Company retains a
$1.6 million nonconvertible, non-voting preferred stock investment in Aesgen.
Dr. Sancilio and Mr. Waters serve on the three-member board of directors of
Aesgen Holding and the Company's executive officers beneficially own the
following percentages of the fully diluted common equity of Aesgen Holding: Dr.
Sancilio, 41.7%, Mr. Waters, 11.4%, Mr. Underwood, 2.3%, Mr. Arato, 0.8% and Mr.
Waldon, 0.8%.
 
     In November 1995, in connection with the purchase by the Goldman Investors
and certain other investors of shares of Preferred Stock described below, Mr.
Waters purchased shares of Preferred Stock (convertible into 119,833 shares of
Common Stock), on substantially the same terms and conditions, including price,
as other purchasers of shares of Preferred Stock. In connection with such
transaction, the Company granted certain stockholders, including Mr. Waters and
Dr. Sancilio, rights to cause the Company to register for sale shares of Common
Stock acquired upon conversion of the Preferred Stock. See "Description of
Capital Stock -- Registration Rights". In addition, in connection with the
Company's issuance of shares of Preferred Stock, Mr. Waters and Dr. Sancilio
agreed to indemnify the Company against certain matters including the imposition
of certain federal income tax liabilities, if any, in connection with the
Company's election to be treated as an S corporation, final resolution of
certain litigation brought by a former employee of AAI in which a judgment for
approximately $363,000 has been entered against the Company and which is
currently being appealed by the Company, and the payment of any amount due in
connection with the resolution of an assessment against the Company of a North
Carolina use tax deficiency of approximately $340,000 plus penalties and
interest assessed against the Company. In addition, and as part of the same
transaction, Mr. Waters and Dr. Sancilio have agreed to sell to AAI up to a
total of 242,539 shares of Common Stock to provide the shares for issuance
pursuant to the 1995 Stock Option Plan. Such shares are required to be sold by
Mr. Waters and Dr. Sancilio upon the exercise of options under the 1995 Plan at
the exercise price of such options. As of May 15, 1996, options to acquire
241,700 shares of Common Stock have been granted under the 1995 Stock Option
Plan at an exercise price per share of $8.35.
 
     The Company loaned $9,991 to Dr. Sancilio in 1993 and $158,305 in 1994,
which loans were repaid in full in November 1995. Such personal loans were
evidenced by two promissory notes, at annual rates of 6.5% and 8%, respectively.
 
     The Company loaned $82,775 to Mr. Underwood in 1993 in connection with a
purchase of shares of Class B Common Stock, all of which was outstanding in
1995. Such loan is evidenced by a promissory note, which bears interest at an
annual rate of 6.15% and is payable, if not paid sooner, on March 30, 1998. At
May 31, 1996, the outstanding principal amount of such promissory note was
$82,775.
 
     The Company loaned $113,865 to Mr. Waldon in connection with his purchase
of 105,453 shares of Class B Common Stock in November 1995 for $30,000 and
income tax liabilities arising in such transaction. Such loan is evidenced by
two promissory notes which bear interest at an annual rate of 6.25% and interest
is payable biweekly. Mr. Waldon's shares of Class B Common Stock are pledged to
secure such loans, and Mr. Waldon has granted the Company an option to
repurchase such shares at the initial purchase price plus a formula amount,
which option will terminate upon the completion of this Offering. At May 31,
1996 the outstanding aggregate principal amount of such promissory notes was
$113,865.

CERTAIN BUSINESS RELATIONSHIPS
 
     In November 1995, the Goldman Investors and certain other investors
purchased shares of Preferred Stock of the Company. After giving effect to the
conversion of all outstanding shares of Preferred Stock and Class B Common Stock
into shares of Common Stock, which will occur upon the completion of the
Offering, the Goldman Investors will own 2,276,832 shares of Common Stock, which
were purchased at $8.35 per share. In connection with such transaction, the
Company granted the Goldman Investors certain rights to cause the Company to
register for sale shares of Common Stock acquired upon conversion of the
Preferred Stock. See "Description of Capital Stock -- Registration Rights".
Pursuant to a Stockholder Agreement entered into in November 1995 in connection
with the purchase of Preferred Stock, the Goldman Investors have the right to
designate one member of the Board of Directors for so long as the Goldman
Investors and their affiliates (which include Goldman, Sachs & Co.) beneficially
own 10% or more of the outstanding shares of Common Stock. Pursuant to such
Agreement, Mr. Gleberman, a general partner of Goldman, Sachs & Co., serves as
one of the Company's directors. See "Management".
 
     In connection with the purchase by the Goldman Investors and certain other
investors of shares of Preferred Stock in November 1995, the Company agreed that
so long as the Goldman Investors beneficially own 5% or more of the outstanding
shares of Common Stock, the Company will retain Goldman, Sachs & Co. or an
affiliate to perform all investment banking services for the Company for which
an investment banking firm is retained and to serve as managing underwriter of
any offering of the Company's capital stock, including the Offering, on
customary terms, consistent with an arm's-length transaction. In the event that
the Company and Goldman, Sachs & Co. or their affiliate cannot agree to the
terms of such engagement after good faith discussions, the agreement permits the
Company to engage any other investment banking firm, although Goldman, Sachs &
Co. is entitled to serve as co-managing underwriter in any underwritten offering
of the Company's capital stock. The Company has agreed to indemnify Goldman,
Sachs & Co. and its affiliates against certain liabilities, including
liabilities under the Securities Act.
 
     Approximately 17.4% of the capital stock of Endeavor on a fully diluted
basis and 13.6% of the capital stock of Aesgen Holding on a fully diluted basis
is held by the Goldman Investors. Mr. Gleberman, a general partner of Goldman,
Sachs & Co., serves on the three-member board of directors of Aesgen Holding.
 
     In November 1995, Noro-Moseley Partners III ("Noro-Moseley"), a venture
capital limited partnership, purchased shares of Preferred Stock. After giving
effect to the conversion of all outstanding shares of Preferred Stock and Class
B Common Stock into shares of Common Stock, which will occur upon completion of
this Offering, Noro-Moseley will own 119,833 shares of Common Stock, which were
purchased at a $8.35 per share. In connection with such transaction, the Company
granted Noro-Moseley certain rights to cause the Company to register for sale
shares of Common Stock acquired upon conversion of the Preferred Stock. See
"Description of Capital Stock -- Registration Rights". The holders of Preferred
Stock were granted the right to designate one director, which right expires upon
completion of the Offering. Such holders have agreed that as long as the Goldman
Investors beneficially own 10% or more of the outstanding shares of Common Stock
they will vote their shares in favor of the Goldman Investors' designee.
Noro-Moseley also currently owns 14.2% of the capital stock of Endeavor on a
fully diluted basis and 0.9% of the capital stock of Aesgen Holding on a fully
diluted basis. Charles D. Moseley, Jr., a member of the limited liability

                          DESCRIPTION OF CAPITAL STOCK
 
     Immediately following the closing of this Offering, the authorized capital
stock of the Company will consist of 50 million shares of Common Stock, $.001
par value per share, and 10 million shares of preferred stock, $.001 par value
per share. As of March 31, 1996, and assuming the conversion of each outstanding
share of Preferred Stock into 2,636,331 shares of Common Stock and each
outstanding share of Class B Common Stock into one share of Common Stock, there
were outstanding 13,181,709 shares of Common Stock held of record by 136
stockholders and in April 1996, the Company issued options to purchase a total
of 450,444 shares of Common Stock.
 
     The following summary of certain provisions of the Common Stock and
preferred stock does not purport to be complete and is subject to, and qualified
in its entirety by, the provisions of the Company's Restated Certificate of
Incorporation, which shall become effective upon completion of this Offering,
which is 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 STOCK
 
     Upon the closing of this Offering, the Company's Restated Certificate of
Incorporation will authorize the issuance of up to 50 million shares of Common
Stock, $.001 par value per share. Holders of Common Stock are entitled to one
vote for each share held on all matters submitted to a vote of stockholders and
do not have cumulative voting rights. Accordingly, holders of a majority of the
shares of Common Stock entitled to vote in any election of directors may elect
all of the directors standing for election. Holders of Common Stock 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 stock. Upon the
liquidation, dissolution or winding up of the Company, the holders of Common
Stock 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 stock. Holders of
Common Stock have no preemptive, subscription, redemption or conversion rights.
The outstanding shares of Common Stock are, and the shares offered by the
Company in this Offering will be, when issued and paid for, fully paid and
nonassessable.
 
PREFERRED STOCK
 
     Upon the closing of this Offering, all outstanding shares of the Preferred
Stock will be converted into shares of Common Stock. See Note 11 of Notes to
Consolidated Financial Statements for a description of the Preferred Stock. The
Board of Directors is authorized, subject to any limitations prescribed by
Delaware law, to provide for the issuance of additional shares of preferred
stock 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) without any further vote or action by the stockholders. The
Board of Directors may authorize the issuance of preferred stock with voting or
conversion rights that could adversely affect the voting power or other rights
of the holders of Common Stock. Such issuance could have the effect of
decreasing the market price of the Common Stock. Thus, the issuance of preferred
stock 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 shares of
preferred stock.
 
OPTIONS
 
     As of May 31, 1996, there were outstanding options to purchase an aggregate
of 450,444 shares of Common Stock, at an exercise price of $8.35 per share
awarded under the Company's 1995 Stock Option Plan and 1996 Stock Option Plan.
See "Management -- Stock Option and Restricted Stock Award Plans". Dr. Sancilio
and Mr. Waters have granted the Company an option to purchase shares of
 
                                       53
<PAGE>   59
 
Class B Common Stock (or Common Stock following the completion of this Offering)
to fund the purchase of the 242,538 shares under the 1995 Option Plan at the
price per share for each option under the 1995 Option Plan.
 
REGISTRATION RIGHTS
 
     Upon the completion of this Offering, the holders of approximately
13,076,206 shares of Common Stock (which include Dr. Sancilio, Mr. Waters and
the Goldman Investors), including up to 12,629,407 shares issuable upon the
conversion of outstanding shares of Class B Common Stock and Preferred Stock
(the "Registrable Securities"), will have certain rights with respect to the
registration of those shares under the Securities Act. If requested by any of
such stockholders, including Dr. Sancilio, Mr. Waters or the Goldman Investors,
the Company must file a registration statement under the Securities Act covering
all Registrable Securities requested to be included by such holders of
Registrable Securities. The Company may be required to effect up to three such
registrations at its expense (other than underwriting discounts and commissions)
and thereafter may be required to effect additional registrations upon
reimbursement for expenses by participating stockholders. The Company has the
right to delay any such registration for up to 180 days under certain
circumstances. Such stockholders' demand registration rights will expire when
such stockholder, together with its affiliates, cease to beneficially own
Registrable Securities (i) equal to 10% of the then outstanding shares of Common
Stock or (ii) having an aggregate market value of at least $30 million.
 
     In addition, if the Company proposes to register any of its shares of
Common Stock under the Securities Act other than in connection with a Company
employee benefit plan or a corporate reorganization, the holders of Registrable
Securities may require the Company to include all or a portion of their shares
in such registration, subject to certain priorities among them, although a
co-managing underwriter of any such offering unaffiliated with any holder of
Registrable Securities may limit the number of shares in such registration. All
expenses incurred in connection with such registrations (other than
underwriters' discounts and commissions) will be borne by the Company.
 
DELAWARE LAW AND CERTAIN PROVISIONS OF THE COMPANY'S RESTATED CERTIFICATE OF
INCORPORATION AND BY-LAWS
 
     Upon completion of this Offering, the Company will be subject to the
provisions of Section 203 of the General Corporation Law of Delaware (the
"Delaware General Corporation Law"). Section 203 prohibits a publicly held
Delaware corporation from engaging in a "business combination" with an
"interested stockholder" for a period of three years after the date of the
transaction in which the person became an interested stockholder, unless the
business combination is approved in a prescribed manner. A "business
combination" includes mergers, asset sales and other transactions resulting in a
financial benefit to the interested stockholder. Subject to certain exceptions,
an "interested stockholder" is a person who, together with affiliates and
associates, owns, or within three years did own, 15% or more of the
corporation's voting stock.
 
     The Restated Certificate of Incorporation, which will be effective upon the
closing of this Offering, provides for the division of the Board of Directors
into three classes as nearly equal in size as possible with staggered three-year
terms. In addition, the Restated Certificate of Incorporation provides that
directors may be removed only for cause by the affirmative vote of the holders
of two-thirds of the shares of capital stock of the Company entitled to vote.
Under the Restated Certificate of Incorporation, any vacancy on the Board of
Directors, however occurring, including a vacancy resulting from an enlargement
of the Board of Directors, may only be filled by vote of a majority of the
directors then in office. The classification of the Board of Directors and the
limitations on the removal of directors and filling of vacancies could have the
effect of making it more difficult for a third party to acquire, or of
discouraging a third party from acquiring, control of the Company.
 
     The Delaware General Corporation Law provides generally that the
affirmative vote of a majority of the shares entitled to vote on any matter is
required to amend a corporation's certificate of incorporation
 
                                       54
<PAGE>   60
 
or by-laws, unless the certificate of incorporation or by-laws, as the case may
be, requires a greater percentage. The Restated Certificate of Incorporation and
the By-laws, which will be effective immediately upon the completion of this
Offering, require the affirmative vote of the holders of at least 75% of the
shares of capital stock of the Company issued and outstanding and entitled to
vote to amend or repeal any of the provisions described in the prior paragraph.
 
     The Restated Certificate of Incorporation contains certain provisions
permitted under the Delaware General Corporation Law relating to the liability
of directors. The provisions eliminate a director's liability for monetary
damages for a breach of fiduciary duty, except in certain circumstances
involving wrongful acts, such as the breach of a director's duty of loyalty or
acts or omissions that involve intentional misconduct or a knowing violation of
law. The limitation of liability described above does not alter the liability of
directors and officers of the Company under federal securities laws.
Furthermore, the Restated Certificate of Incorporation contains provisions to
indemnify the Company's directors and officers to the fullest extent permitted
by the Delaware General Corporation Law. These provisions do not limit or
eliminate the right of the Company or any stockholder to seek non-monetary
relief such as an injunction or rescission in the event of a breach by a
director or an officer of a duty owed to the Company. The Company believes that
these provisions will assist the Company in attracting and retaining qualified
individuals to serve as directors.
 
     In addition, the Restated Certificate of Incorporation contains certain
provisions addressing potential conflicts of interest between the Company and
any entity in which any directors of the Company have a financial interest (a
"Related Entity"). Under these provisions, any contract, agreement, arrangement
or transaction between the Company and a Related Entity (a "Related
Transaction") shall not be void or voidable solely for the reason that the
Company and a Related Entity are parties thereto, if: (i) the material facts of
the Related Transaction are disclosed or are known to the Board of Directors (or
a committee thereof) and the Board (or committee) in good faith authorizes,
approves or ratifies the Related Transaction by the affirmative vote of a
majority of the disinterested directors on the Board of Directors (or such
committee), even though the disinterested directors may be less than a quorum;
(ii) the material facts of the Related Transaction are disclosed or are known to
the holders of the then outstanding voting shares of the Company entitled to
vote thereon, and the Related Transaction is specifically approved or ratified
in good faith by the affirmative vote of the holders of a majority of the then
outstanding voting shares not owned by the interested directors or Related
Entity, as the case may be, even though such holders may be less than a quorum;
(iii) such Related Transaction is effected pursuant to and consistent with terms
and conditions specified in any arrangements, standards or guidelines that are
in good faith authorized, approved or ratified, after disclosure or knowledge of
the material facts related thereto, by the affirmative vote of a majority of the
disinterested directors on the Board of Directors (or committee thereof), or by
the affirmative vote of the holders of a majority of the then outstanding voting
shares of the Company not owned by the interested directors or Related Entity,
as the case may be, even though the disinterested directors or such holders may
be less than a quorum; or (iv) such Related Transaction was fair to the Company.
 
     The Restated Certificate of Incorporation also provides that any such
contract, agreement, arrangement or transaction authorized, approved or
effected, and each of such arrangements, standards or guidelines so authorized
or approved, as described in (i), (ii) or (iii) above, shall be conclusively
deemed to be fair to the Company and its stockholders. If, however, such
authorization or approval is not obtained, or such contract, agreement,
arrangement or transaction is not so effected, no presumption shall arise that
such contract, agreement, arrangement or transaction, or such arrangements,
standards or guidelines, are not fair to the Company and its stockholders.
 
     The By-laws of the Company establish an advance notice procedure for
stockholder proposals to be brought before a meeting of stockholders of the
Company and for nominations by stockholders of candidates for election as
directors at an annual meeting or a special meeting at which directors are to be
elected. Subject to any other applicable requirements, only such business may be
conducted at a meeting of stockholders as has been brought before the meeting
by, or at the direction of, the Board of Directors or by a stockholder who has
given to the Secretary of the Company timely written notice, in
 
                                       55
<PAGE>   61
 
proper form, of the stockholder's intention to bring that business before the
meeting. The presiding officer at such meeting has the authority to make such
determinations. Only persons who are selected and recommended by the Board of
Directors or by a committee of the Board of Directors designated to make
nominations, or who are nominated by a stockholder who has given timely written
notice, in proper form, to the Secretary prior to a meeting at which directors
are to be elected, will be eligible for election as directors of the Company.
 
     To be timely, notice of nominations or other business to be brought before
any meeting must be received by the Secretary of the Company not later than 120
days in advance of the anniversary date of the Company's proxy statement for the
previous year's annual meeting or, in the case of special meetings, at the close
of business on the tenth day following the date on which notice of such meeting
is first given to stockholders.
 
     The notice of any stockholder proposal or nomination for election as a
director must set forth the various information required under the By-laws. The
person submitting the notice of nomination and any person acting in concert with
such person must provide, among other things, the name and address under which
they appear on the Company's books (if they so appear) and the class and number
of shares of the Company's capital stock that are beneficially owned by them.
 
TRANSFER AGENT AND REGISTRAR
 
     The transfer agent and registrar for the Common Stock is First Union
National Bank of North Carolina.
 
                        SHARES ELIGIBLE FOR FUTURE SALE
 
     Upon completion of this Offering, the Company will have 15,881,709 shares
of Common Stock outstanding (16,286,709 shares if the Underwriters'
over-allotment option is exercised in full). Of these shares, the 2,700,000
shares offered hereby will be freely tradeable without restrictions or further
registration under the Securities Act, except for any shares purchased by
"affiliates" of the Company, as that term is defined in Rule 144 under the
Securities Act, which will be subject to the resale limitations imposed by Rule
144, as described below. All of the remaining 13,181,709 shares of Common Stock
outstanding will be "restricted securities" within the meaning of Rule 144.
Taking into consideration the effect of lock-up agreements described below (the
"Lock-Up Agreements"), 10,439,875 shares will become eligible for sale beginning
180 days after the date of effectiveness of the Registration statement of which
this Prospectus is a part, subject to the provisions of Rule 144 under the
Securities Act or Rule 701 under the Securities Act. The remaining 2,636,331
restricted securities will not be eligible for resale under Rule 144 until after
the expiration of a two-year holding period from the date such restricted
securities were acquired from the Company or an affiliate, and may be resold in
the public market only in compliance with the registration requirements of the
Securities Act or pursuant to a valid exemption therefrom; all of these shares
are subject to the Lock-Up Agreements. Of such 13,181,709 restricted shares,
13,076,206 shares are beneficially owned by stockholders who have the right to
have their shares registered by the Company under the Securities Act. The
remaining 105,503 shares were awarded pursuant to the Restricted Stock Plan and,
as discussed below, are subject to certain vesting requirements and may not be
transferred prior to vesting.
 
     In general, under Rule 144 as currently in effect, a person (or persons
whose shares are required to be aggregated) whose restricted securities have
been outstanding for at least two years, including a person who may be deemed an
"affiliate" of the Company, may only sell a number of shares within any
three-month period that does not exceed the greater of (i) one percent of the
then outstanding shares of the Company's Common Stock (approximately 158,817
shares after this Offering assuming the Underwriters' overallotment option is
not exercised) or (ii) the average weekly trading volume in the Company's Common
Stock in the four calendar weeks immediately preceding such sale. Sales under
Rule 144 are also subject to certain requirements as to the manner of sale,
notice and the availability of current public information about the Company. A
person who is not an affiliate of the issuer, has not been an affiliate within
three months prior to the sale and has owned the restricted securities for at
least three
 
                                       56
<PAGE>   62
 
years is entitled to sell such shares under Rule 144(k) without regard to any of
the limitations described above. The Securities and Exchange Commission (the
"Commission") recently has proposed amendments to Rule 144 to reduce the holding
periods. If adopted such amendments would have a material effect on the timing
of when shares of Common Stock will become eligible for resale.
 
     Certain shares issued or issuable upon the exercise of options granted by
the Company or acquired pursuant to the Company's Restricted Stock Award Plan,
the Option Plans and other plans prior to the date of this Prospectus may be
eligible for sale in the public market pursuant to Rule 701 under the Securities
Act. In general, Rule 701 permits resales of shares issued pursuant to certain
compensatory benefit plans and contracts commencing 90 days after the issuer
becomes subject to the reporting requirements of the Securities Exchange Act of
1934, as amended (the "Exchange Act"), in reliance upon Rule 144, but without
compliance with certain restrictions of Rule 144, including the holding period
requirements. As of April 30, 1996, the Company has granted options covering
450,444 shares of Common Stock, all of which become exercisable at various times
in the future and 105,503 restricted shares of Common Stock, a portion of which
are subject to forfeiture by the holder in certain events, do not vest until two
years after the completion of this Offering, subject to immediate vesting upon
certain change-in-control transactions, and may not be transferred prior to
vesting. Any shares of Common Stock issued upon the exercise of these options
and such restricted shares will be eligible for sale pursuant to Rule 701,
subject to Lock-Up Agreements.
 
     In addition to shares issuable pursuant to the exercise of outstanding
options, the Company has reserved 287,721 additional shares for issuance under
the Option Plans. When issued, these shares may only be sold within the
limitations of Rule 144 or pursuant to registration under the Securities Act.
The Company intends to file a registration statement covering shares of Common
Stock to be acquired upon the exercise of options granted under the Option
Plans. Once such a registration statement becomes effective, persons acquiring
shares pursuant to the exercise of options granted under the Option Plans,
including affiliates, will be able to sell the shares in the public market
without regard to the two-year holding period of Rule 144.
 
     The Company has agreed that, during the period beginning from the date of
this Prospectus and continuing to and including the date 180 days after the date
of the Prospectus, they will not offer, sell, contract to sell or otherwise
dispose of any securities of the Company (other than pursuant to employee stock
option plans existing, or on the conversion or exchange of convertible or
exchangeable securities outstanding, on the date of this Prospectus) which are
substantially similar to the shares of Common Stock or which are convertible or
exchangeable into securities which are substantially similar to the shares of
Common Stock without the prior written consent of the representatives, except
for the shares of Common Stock offered in connection with the Offering. The
Company has also agreed that during such 180-day period it will not accelerate
the vesting of any shares of Common Stock awarded under the Restricted Stock
Plan or deliver certificates representing any shares awarded under the
Restricted Stock Plan. All other stockholders and all option holders will agree
that, during the period beginning from the date of this Prospectus and
continuing to and including the date 180 days after the date of this Prospectus,
they will not offer, sell, contract to sell or otherwise dispose of any
securities of the Company (other than on the conversion or exchange of
convertible or exchangeable securities or exercise of options outstanding on the
date of this Prospectus) which are substantially similar to the shares of Common
Stock or which are convertible or exchangeable into securities which are
substantially similar to the shares of Common Stock without the prior written
consent of the representatives. Certain stockholders will have registration
rights relating to the Common Stock acquired upon conversion thereof, but such
rights will not be exercisable until after such 180-day period. For a discussion
of these matters, see "Description of Capital Stock -- Registration Rights" and
"Shares Eligible for Future Sale".

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors
and Stockholders of
Applied Analytical Industries, Inc. (AAI)
 
     In our opinion, the accompanying consolidated balance sheets and the
related consolidated statements of income, of stockholders' equity and of cash
flows present fairly, in all material respects, the financial position of
Applied Analytical Industries, Inc. and subsidiaries at December 31, 1995 and
1994, and the results of their operations and their cash flows for each of the
three years in the period ended December 31, 1995, in conformity with generally
accepted accounting principles. These financial statements are the
responsibility of the Company's management; our responsibility is to express an
opinion on these financial statements based on our audits. We conducted our
audits of these statements in accordance with generally accepted auditing
standards which require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for the opinion expressed above.

1.  BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES
 
  Description of the Business
 
     Operations of Applied Analytical Industries, Inc. (the "Company" or "AAI")
consist primarily of contract product development and support services for the
pharmaceutical and biotechnology industries. Activities include formulation
development, drug physicochemical analysis and synthesis, clinical supply and
niche manufacturing, and regulatory and compliance consulting.
 
  Basis of presentation
 
     The consolidated financial statements include the accounts of the Company
and its wholly-owned subsidiaries, Applied Analytical Industries Italy, S.r.I.
and Applied Analytical Industries Learning Center, Inc. All material
intercompany accounts and transactions are eliminated in consolidation. The
Company has a 43% ownership (38% on a fully diluted basis) in Endeavor
Pharmaceuticals, Inc. ("Endeavor") which is accounted for under the equity
method (Note 3).
 
  Cash and cash equivalents
 
     The Company considers all highly liquid debt investments purchased with an
original maturity of three months or less to be cash equivalents.
 
  Property and equipment
 
     Property and equipment are recorded at cost. Maintenance and repairs are
charged to expense as incurred and costs of improvements and renewals are
capitalized. Depreciation is recognized using the straight-line method over the
estimated useful lives of the assets ranging from 3 to 31.5 years.
 
  Intangible assets
 
     Intangible assets include deferred loan costs, patents and other intangible
assets. Loan costs are amortized over the term of the related loan. Patents are
recorded at cost and are amortized over seventeen years commencing when the
patent is granted. Other intangible assets are amortized over seven and fifteen
years utilizing the straight-line method. Intangible assets are included in
other assets in the accompanying financial statements.
 
  Long-term investment
 
     Long-term investment includes nonconvertible, non-voting, mandatorily
redeemable preferred stock of a related party (Note 7) which is carried at
original cost. Write-downs are taken for impairment in the carrying value
considered to be permanent. Long-term investment is included in other assets in
the accompanying financial statements.
 
  Revenue recognition
 
     Revenues from contract pharmaceutical product development and support
services are related to both fixed priced and hourly based customer contracts
and are recognized on a percentage of completion basis. Work-in-progress
represents revenues recognized before amounts may be billed under contract
terms. Contracts in progress are reviewed quarterly; sales and earnings are
adjusted in current accounting periods based on revisions in contract sales
value and estimated costs to complete. Provisions for estimated losses on
contracts are recorded in the quarter identified.

                   (DOLLARS IN THOUSANDS, EXCEPT SHARE DATA)
 
     Licensing revenues from Company funded development projects are primarily
recognized as significant contract requirements are met. Royalty revenues are
recognized as earned in accordance with contract terms.
 
  Income taxes
 
     The financial statements of the Company do not include a provision for
income taxes for the years ended December 31, 1993 and 1994 because the taxable
income or loss of the Company, until November 17, 1995, passed directly to the
stockholders under the S corporation election. As a result of the November 17,
1995 preferred stock issuance described in Note 6, the Company no longer
qualified as an S corporation and became subject to federal and state income
taxes. Accordingly, the Company began accounting for income taxes in accordance
with Statement of Financial Accounting Standards No. 109 ("SFAS 109"),
"Accounting For Income Taxes." SFAS 109 is an asset and liability approach that
requires the recognition of deferred tax assets and liabilities for the expected
future tax consequences of events that have been recognized in different periods
in the Company's financial statements and tax returns. In estimating future tax
consequences, SFAS 109 generally considers all expected future events other than
enactment of changes in tax law or rates. If it is "more likely than not" that
some portion or all of a deferred tax asset will not be realized, a valuation
allowance is recorded.
 
     For informational purposes, the statement of income includes a pro forma
income tax provision on taxable income for financial reporting purposes using
federal and state income tax rates that would have resulted if the Company had
been subject to corporate income taxes during these periods.
 
  Unaudited pro forma earnings per share and unaudited pro forma balance sheet
 
     The Company's historical capital structure is not indicative of its
prospective structure given (i) the conversion of the Series A convertible
preferred stock and Class B common stock into Class A common stock concurrent
with the closing of the Company's anticipated initial public offering (see Note
11). Accordingly, historical net earnings per common share is not considered
meaningful and has not been presented herein. The calculation of the shares used
in computing pro forma net earnings per share includes the effect of the
conversion of the convertible preferred stock and Class B common stock described
in Note 6 into shares of Class A common stock concurrent with the closing of the
Company's anticipated initial public offering as if they were converted as of
January 1, 1995. Also, pursuant to Securities and Exchange Commission Staff
Accounting Bulletin No. 83, common stock or equivalent shares from convertible
preferred stock or stock options and awards sold or issued at prices below the
anticipated initial public offering price per share in the twelve months
preceding the initial filing have been included in the calculation as if
outstanding for all periods presented.
 
  Interim financial information
 
     Interim financial information for the three month periods ended March 31,
1995 and 1996 included herein is unaudited; however, in the opinion of the
Company, the interim financial information includes all adjustments, consisting
of only normal recurring adjustments, necessary for a fair presentation of the
results for the interim periods. The results of operations for the three months
ended March 31, 1996 are not necessarily indicative of the results to be
expected for the year.
 
  Fair value of financial instruments
 
     The carrying values of cash and cash equivalents, accounts receivable,
current liabilities and mandatorily redeemable preferred stock investment
approximate the fair value. Substantially all of the Company's long-term debt is
subject to variable interest rates; because these variable rates approximate

                   (DOLLARS IN THOUSANDS, EXCEPT SHARE DATA)
 
a market rate of interest at December 31, 1995, the carrying amount of long-term
debt approximates fair value at that date. It is not practicable to estimate the
fair value of the Company's equity investment as there exists no readily
determinable market for investments in such entities.
 
  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 reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
  New Accounting Pronouncements
 
     In 1995, the Financial Accounting Standards Board issued two new
statements, which the Company will adopt in the fiscal year ending December 31,
1996, related to accounting for impairment of long-lived assets and accounting
for stock compensation. The Company intends to adopt the disclosure alternative
for stock compensation and does not expect the effect of adoption of either
statement to result in a material impact to the Company's financial position or
results of operations.

3.  EQUITY INVESTMENT
 
     In April 1994, AAI organized Endeavor with Berlex Laboratories, Inc. and
several other investors to fund the development of hormone pharmaceutical
products, initially focusing on several generic hormone products already under
development by AAI. AAI obtained a 47% equity interest in Endeavor through
contribution of its accumulated product research and development and technical
know-how. The other investors contributed cash in exchange for their interests
which, for all investors, was in the form of convertible preferred stock. Based
on a subsequent cash infusion by a new investor in November 1995, the Company's
interest in Endeavor was diluted to 43% (38% on a fully diluted basis).
 
     AAI accounts for its investment in Endeavor under the equity method. AAI's
initial investment was recorded at zero, with gain for its share of the cash
contributed to Endeavor by the other investors deferred over the period the
proceeds from such equity are expended by Endeavor. Due to a commitment to
provide financial support under a line of credit, AAI recognized a liability for
its proportionate share of Endeavor's losses, net of amortization of the
deferred gain. As a result of the November 1995 cash infusion from a third
party, the Company was repaid all amounts outstanding under the line of credit
and AAI's obligation to provide any further funding under the line of credit
terminated in the fourth quarter of

1995. Since the Company has no requirement to provide any additional funding to
Endeavor, the previously recorded liability was reversed in the fourth quarter
of 1995.

     In December 1992, the Company and a bank entered into an agreement, as
amended March 28, 1996, providing for a credit facility comprised of two
revolving loans, a term loan and a capital expenditure loan (the "Loan
Agreement"). Amounts outstanding under this Loan Agreement are secured by
substantially all of the Company's assets, excluding equity investments. There
is an annual fee of 1/4% applied to the unutilized revolving loan commitment.
 
     At December 31, 1994 and 1995, the Company had outstanding borrowings of
$3,257 and $2,331, respectively, on the revolving loans. The revolving loans are
due August 1996. At December 31, 1995, the Company had approximately $2,669
available borrowing capacity under the revolving loans. The average interest
rate on revolving loan borrowings was 8.86% during 1995.
 
     During 1988, the Company secured financing for the acquisition and
construction of facilities and equipment with variable rate North Carolina
Industrial Revenue Bonds ("IRB") in the amount of $3,500. The bonds are payable
at the option of the bondholders; however, the bonds are classified as long-term
because a bank is responsible for paying the bondholders under a standby letter
of credit in the amount of $1.8 million expiring in June 1997. An annual
commitment fee of 3/4% is charged on the commitment amount.
 
     Under the terms of the Loan Agreement and irrevocable letter of credit
agreement, the Company is required to comply with various covenants including,
but not limited to, those pertaining to working capital, maintenance of certain
financial ratios, purchase of property and equipment and incurring additional
indebtedness.

     A reconciliation of actual income tax expense to the amount computed by
applying the federal statutory income tax rate yields no material differences.
 
     Deferred income taxes arise from temporary differences between the tax
bases of assets and liabilities and their reported amounts in the financial
statements. The components of deferred tax liabilities and assets as of November
17, 1995 and December 31, 1995 were as follows:

     No valuation allowance has been provided against the deferred tax assets at
either November 17, 1995 or December 31, 1995.
 
6. STOCKHOLDERS' EQUITY
 
  Preferred stock
 
     On November 17, 1995, the Company issued 883 shares of $.01 par value
Series A Convertible Preferred Stock ("Preferred Stock") for net proceeds of
$21.5 million. The Preferred Stock has a liquidation preference of $22.0
million. Each share is entitled to receive dividends equivalent to dividends
received by holders of common stock based on the number of shares of common
stock into which the Preferred Stock is convertible. Each share is convertible,
at the option of the holder, into units consisting of 126.5 shares of Class A
Voting Common Stock ("Class A Stock") and 2,859 shares of Class B Non-voting
Common Stock ("Class B Stock"). The Preferred Stock is mandatorily convertible
into common stock upon the closing of an initial public stock offering ("IPO")
that meets certain conditions. Prior to any conversion, the holders of the
Preferred Stock have voting rights consistent with holders of Class A Stock;
special voting rights to approve certain defined transactions relating to
capital expenditures, additional borrowings, granting of certain stock options
and issuing common stock; one Board seat appointment; and certain
transferability rights less stringent than those stipulated by the Company's
Stockholders' Agreement. The Company will reserve 111,700 and 2,524,434 shares
of Class A Stock and Class B Stock, respectively, for issuance upon conversion
of the Preferred Stock.
 
  Common stock
 
     The Company sold 306,889, 103,351 and 105,453 shares of Class B Stock to
officers in 1993, 1994 and 1995, respectively. The purchase price for the
105,453 shares acquired in 1995 by an officer of the Company was determined to
be approximately $272 below the estimated market value of the Class B Stock and
such difference has been recognized as compensation expense in the accompanying
1995 consolidated statement of income.
 
     Any offer to sell outstanding Class B Stock by a stockholder must first be
made to the Company and then to other stockholders. Certain other restrictions,
some of which lapse concurrent with an IPO, also exist with respect to
transferability and forfeiture of Class B Stock.
 
  Dividends
 
     Concurrent with the Company's change to a C corporation in November 1995,
the Company elected to distribute its S corporation retained earnings. 1995
dividends of $7,593 represent S corporation retained earnings distributed. Upon
filing of the final S corporation tax return for the period January 1, 1995 to
November 17, 1995, the final S corporation dividend will be paid during the
second quarter of 1996.
 
  Stock option and award plans
 
     In November 1995, the Company's Board of Directors approved the
implementation of the 1995 Restricted Stock Award Plan ("1995 Award Plan"), the
1995 Stock Option Plan ("1995 Plan") and the 1996 Stock Option Plan ("1996
Plan").
 
  1995 Award Plan
 
     Under the 1995 Award Plan the Company's Board of Directors may issue up to
105,453 shares of Class B Stock. The Board of Directors shall establish the
issue price at its sole discretion. On March 26,

                   (DOLLARS IN THOUSANDS, EXCEPT SHARE DATA)
 
1996 the Company issued 105,453 shares of Class B Stock to certain employees and
officers of the Company which had a fair value of $4.66 per share. As a result,
unearned compensation of approximately $490 was recorded as of the date of
grant. Such compensation expense will be recognized for book purposes over the
vesting period of five years or two years following an IPO.
 
  1995 Plan
 
     Under the 1995 Plan, the Board of Directors may grant options to purchase
up to 242,538 shares of Class B Stock. However, the Company has no obligation to
issue the shares of Class B Stock upon exercise of such options until it has
purchased an equal number of shares from certain existing stockholders. The
exercise price of options granted cannot be less than 75% of the estimated fair
market value of the Company's shares of common stock on the date of grant.
 
     On April 26, 1996, the Company issued options to purchase 241,700 shares of
Class B Stock to employees and officers of the Company at an exercise price of
$8.35 per share, such price being the minimum allowable under the provisions of
the 1995 Plan. The shares vest 25% at each of the six-month, eighteen-month,
thirty-month and forty-two month anniversaries of the grant date. The Company
has not yet purchased any Class B Stock from the existing stockholders.
 
  1996 Plan
 
     Under the 1996 Plan the Board of Directors may grant options to purchase up
to 495,627 newly issued shares of Class B Stock (no more than 210,876 shares
prior to January 1, 1997). The exercise price of options granted cannot be less
than 75% of the estimated fair market value of the Company's shares of common
stock on the date of grant. On April 26, 1996, the Company issued options to
purchase 208,744 shares of Class B Stock to employees and officers of the
Company at an exercise price of $8.35 per share, such price being the minimum
allowable under the provisions of the 1996 Plan.
 
7.  RELATED PARTY TRANSACTIONS
 
  Aesgen, Inc.
 
     While incorporated in July 1994, Aesgen Inc. ("Aesgen") was formally
organized with an affiliate of the Mayo Clinic and MOVA Pharmaceutical
Corporation and funded in April 1995 via issuance of approximately $11 million
of nonconvertible, non-voting, mandatorily redeemable, preferred stock. As the
Company did not intend to hold an equity interest in Aesgen, the Company entered
a series of related transactions commencing in December 1995 to transfer to a
corporation owned by the holders of substantially all of the outstanding capital
stock of the Company, all of its shares of Aesgen common stock in return for $50
(amount paid by AAI for such shares) and such corporation's assumption of an
obligation to invest an additional $1.2 million in Aesgen. The Company retains a
$1.6 million nonconvertible, non-voting, mandatorily redeemable, preferred stock
investment in Aesgen.
 
     The Company provides product development services to Aesgen at terms and
conditions that management believes are similar to those afforded unrelated
entities. AAI recognized approximately $5,558 of net revenues from Aesgen for
the year ended December 31, 1995. AAI also had trade receivables of
approximately $51 from Aesgen and a work-in-process balance of approximately
$1,044 at December 31, 1995. AAI has the right under its development agreement
with Aesgen to provide certain product development and support services to
Aesgen with respect to some generic drugs currently being developed by Aesgen,
provided that AAI's fees for such services are comparable to those of a
competitor. In addition, under such development agreement, the Company has
agreed not to develop, for its own account or any other person, a formulation of
any of the generic products currently under

development for Aesgen and any additional drugs that AAI agrees to develop in
the future for Aesgen under the development agreement.
 
  Endeavor
 
     The Company has agreed, upon the completion of a specified development
milestone, to grant Endeavor an option to lease for 15 years approximately
20,000 square feet of production space intended for use by AAI in manufacturing
Endeavor's products or to purchase that part of the facility. Upon exercise of
the option to lease, Endeavor would be required to pay $2 million to the Company
and may purchase that portion of the facility at its fair market value. If the
option is exercised but AAI fails to perform certain development milestones by a
specified date, AAI must repay the option exercise price to Endeavor. The
facilities subject to the option are currently used by the Company for its
clinical supply and niche manufacturing operations. The Company is expanding its
clinical supply and niche manufacturing facilities to maintain necessary
capacity in the event Endeavor exercises its option. The Company anticipates
that the milestone triggering the commencement of such option will occur in the
third quarter of 1996. The Company has also agreed to permit Endeavor under
certain circumstances the first right to purchase additional proprietary hormone
pharmaceutical products developed by AAI.
 
  Pharmaceutical Seminars, Inc.
 
     On December 29, 1994, the Company purchased, for $290, certain assets of
Pharmaceutical Seminars, Inc. ("PSI"), a company that organized seminars
addressing various pharmaceutical industry topics. PSI was wholly-owned by the
spouses of two of the Company's officers and directors. The Purchase agreement
provided for additional consideration contingent upon the paid attendance at
seminars organized by PSI for conduct in 1995. A total of approximately $84 was
paid as additional consideration. In addition, PSI's previous owners executed
consulting agreements for approximately $5 each to assist the Company in
conducting the seminars scheduled through April 1995.
 
  PharmComm, Inc.
 
     In March 1996, the Company retained PharmComm, Inc. ("PharmComm") to
provide computer software development and related services. PharmComm has both
stockholders and directors that are common to those of the Company. In addition,
the Company licensed certain know-how to PharmComm for $1 million to be paid
from future profits of PharmComm. As PharmComm is not profitable, the Company
has not recognized any licensing revenues in any period presented.
 
  5051 New Centre Drive, LLC
 
     The Company provides accounting services, at no charge, to 5051 New Centre
Drive, LLC, a company affiliated through common ownership. The Company also
leases a portion of a building, at a rate comparable to that of other similar
properties, from 5051 New Centre Drive, LLC.

8.  EMPLOYEE BENEFIT PLAN
 
     The Company has a 401(k) profit-sharing plan covering all employees with
one year of service who have attained the age of eighteen. Participants may
elect to contribute a portion of their compensation annually, subject to
Internal Revenue Service limitations. The Company makes matching contributions
equal to 50% of a participant's contribution up to a certain amount. Additional
Company contributions are at the discretion of the Company's Board of Directors.
Contributions to the Plan were as follows:

     In 1994, the Company received an assessment purporting underpaid sales and
use taxes for the years 1992 through 1994. The Company believes that it has
properly paid sales and use taxes in accordance with applicable laws and has
contested the assessment. No provision with respect to the above matter has been
recorded in the financial statements. In addition, concurrent with the November
17, 1995 preferred stock issuance (see Note 6), two of the Company's
stockholders agreed to indemnify the Company for any losses resulting from this
contingency.

                   (DOLLARS IN THOUSANDS, EXCEPT SHARE DATA)
 
     The Company entered into a three year employment agreement, automatically
extending one year at each anniversary date, with its Chairman and President on
November 17, 1995. This agreement provides for an annual salary of not less than
$250 plus bonus provisions and other benefits. A termination as defined in the
agreement will require the Company to pay any unpaid salary or prorated bonus
through the termination date plus three years salary and other defined
compensation and benefits. Such additional compensation and benefits will be
paid over a period of two years from the date of termination.
 
11.  SUBSEQUENT EVENTS (UNAUDITED)
 
  Stock transactions
 
     In March and April 1996, the Company granted Class B Stock options and
awards pursuant to the related plans approved in November 1995 (see Note 6).
 
  Option agreement
 
     In May 1996, the Company signed an option agreement with a term of six
months to purchase the outstanding shares of a European contract research and
development organization. The Company will pay $1.0 million, to be deposited in
an escrow account, to acquire such option. Such amount would be applied to the
purchase price if the Company elects to exercise such option or returned to the
Company if, upon expiration of the option, certain material conditions are not
satisfied. Significant uncertainties exist whether such conditions could be
satisfied prior to the expiration of the option. The Company does not intend to
exercise such option if the foregoing conditions are not satisfied and can make
no prediction whether such conditions will be satisfied by November 1996. In
addition, the Company may choose to not exercise such option even though the
option conditions may be satisfied, whereby the option fee would be forfeited.
 
  Initial public offering
 
     The Company has initiated a plan to complete an IPO of common stock during
the third quarter of 1996. It is anticipated that upon the closing of such IPO
the Company's current classes of common and preferred stock would convert to one
class of voting common stock on a ratio of 1:126.50 for Class A Stock and Class
B Stock and a ratio of 1:2,859.15 for each Preferred Stock share.
 
  Stock split and reverse stock split
 
     On May 31, 1996 the Board of Directors approved (i) an amendment to the
Certificate of Incorporation of the Company increasing the number of authorized
Class A Stock and Class B Stock shares to 1,000,000 and 30,000,000,
respectively, and (ii) a stock split of 200 shares for 1 share for all AAI
common stock. On June 5, 1996, the Board of Directors authorized a one-for-.6325
reverse split of the Common Stock and Class B Common Stock. All numbers of
common shares and per share amounts in the accompanying financial statements
have been retroactively adjusted to reflect this stock split.

</TABLE>
 
     Under the terms and conditions of the Underwriting Agreement, the
Underwriters are committed to take and pay for all of the shares offered hereby,
if any are taken.
 
     The Underwriters propose to offer the shares of Common Stock in part
directly to the public at the initial public offering price set forth on the
cover page of this Prospectus and in part to certain securities dealers at such
price less a concession of $          per share. The Underwriters may allow, and
such dealers may reallow, a concession not in excess of $          per share to
certain brokers and dealers. After the shares of Common Stock are released for
sale to the public, the offering price and other selling terms may from time to
time be varied by the representatives.
 
     The Company has granted the Underwriters an option exercisable for 30 days
after the date of this Prospectus to purchase up to an aggregate of 405,000
additional shares of Common Stock to cover over-allotments, if any. If the
Underwriters exercise their over-allotment option, the Underwriters have
severally agreed, subject to certain conditions, to purchase approximately the
same percentage thereof that the number of shares to be purchased by each of
them, as shown in the foregoing table, bears to the 2,700,000 shares of Common
Stock offered.
 
     The Company has agreed that, during the period beginning from the date of
this Prospectus and continuing to and including the date 180 days after the date
of the Prospectus, they will not offer, sell, contract to sell or otherwise
dispose of any securities of the Company (other than pursuant to employee stock
option plans existing, or on the conversion or exchange of convertible or
exchangeable securities outstanding, on the date of this Prospectus) which are
substantially similar to the shares of Common Stock or which are convertible or
exchangeable into securities which are substantially similar to the shares of
Common Stock without the prior written consent of the representatives, except
for the shares of Common Stock offered in connection with the Offering. The
Company has also agreed that during such 180-day period it will not accelerate
the vesting of any shares of Common Stock awarded under the Restricted Stock
Plan or deliver certificates representing any shares awarded under the
Restricted Stock Plan. All other stockholders and all option holders have agreed
that, during the period beginning from the date of this Prospectus and
continuing to and including the date 180 days after the date of the Prospectus,
they will not offer, sell, contract to sell or otherwise dispose of any
securities of the Company (other than on the conversion or exchange of
convertible or exchangeable securities or exercise of options outstanding on the
date of this Prospectus) which are substantially similar to the shares of Common
Stock or which are convertible or exchangeable into securities which are
substantially similar to the shares of Common Stock without the prior written
consent of the representatives. Certain stockholders will have registration
rights relating to the Common Stock acquired upon conversion thereof, but such
rights will not be exercisable until after such 180-day period. For a discussion
of these matters, see "Description of Capital Stock -- Registration Rights" and
"Shares Eligible for Future Sale".

     Goldman, Sachs & Co. and certain of their affiliates own 2,276,832 shares
of Common Stock, representing 17.3% of the outstanding Common Stock of the
Company and, upon completion of the Offering, will own approximately 14.3% of
the outstanding Common Stock. See "Principal Stockholders". Goldman, Sachs & Co.
and such affiliates are subject to the 180-day lock-up that applies to other
stockholders as described above. Notwithstanding such restriction, however,
Goldman, Sachs & Co. and their affiliates will be permitted to engage in
stabilization, brokerage and ordinary course of business transactions and will
be permitted, pursuant to a registration statement under the Securities Act
maintained by the Company, to sell Common Stock and related securities in
connection with market-making transactions from time to time, both during and
after the 180-day period. See "Shares Eligible for Future Sale".
 
     Goldman, Sachs & Co. and certain of their affiliates maintain certain
contractual relationships with the Company. See "Certain Transactions". As long
as Goldman, Sachs & Co. and certain of their affiliates beneficially own 10% or
more of the outstanding shares of Common Stock, certain affiliates of Goldman,
Sachs & Co. have the right to designate one member of the Board of Directors of
the Company. Pursuant to such agreement, a general partner of Goldman, Sachs &
Co. serves as one of the Company's directors. After the consummation of the
Offering, such director is expected to continue in office. See "Management".
 
     The representatives of the Underwriters have informed the Company that they
do not expect sales to accounts over which the Underwriters exercise
discretionary authority to exceed five percent of the total number of shares of
Common Stock offered by them.
 
     Certain of the Underwriters have provided from time to time, and expect to
provide in the future, investment banking services to the Company, for which
such Underwriters have received and will receive customary fees and commissions.
 
     The Underwriters have reserved for sale, at the initial public offering
price, shares of Common Stock for employees of the Company who have expressed an
interest in purchasing such shares of Common Stock in the Offering. It is
expected that such persons will purchase, in the aggregate, no more than 5% of
the Common Stock offered in the Offering. The number of shares available for
sale to the general public in the Offering 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.
 
     Prior to this Offering, there has been no public market for the shares. The
initial public offering price will be negotiated among the Company and the
representatives of the Underwriters. Among the factors to be considered in
determining the initial public offering price of the Common Stock, in addition
to prevailing market conditions, will be the Company's historical performance,
estimates of the business potential and earnings prospects of the Company, an
assessment of the Company's management and the consideration of the above
factors in relation to market valuation of companies in related businesses.
 
     The Company has been advised by Goldman, Sachs & Co. that, subject to
applicable laws and regulations, Goldman, Sachs & Co. currently intend to make a
market in the Common Stock following completion of the Offering. However, they
are not obligated to do so and any market-making may be discontinued at any time
without notice. In addition, such market-making activity will be subject to the
limits imposed by the Securities Act and the Exchange Act. There can be no
assurance that an active trading market will develop or be sustained following
the completion of the Offering. See "Risk Factors -- No Prior Market; Possible
Volatility of Stock Price".
 
     The Company and the Underwriters have entered into an agreement with
respect to such market-making activities. Because of the affiliation of Goldman,
Sachs & Co. with the Company, Goldman, Sachs & Co. will be required to deliver a
current prospectus to any purchaser in connection with any such market-making
transactions. The Company has agreed to make from time to time certain
amendments or supplements to the Prospectus and to pay certain expenses relating
to such amendments or supplements.

duty. The Restated Certificate of Incorporation will provide that a director or
officer of the Company (a) shall be indemnified by the Company against all
expenses (including attorneys' fees), judgments, fines and amounts paid in
settlement incurred in connection with any litigation or other legal proceeding
(other than an action by or in the right of the Company) brought against him by
virtue of his position as a director or officer of the Company if he acted in
good faith and in a manner he reasonably believed to be in, or not opposed to,
the best interests of the Company, and, with respect to any criminal action or
proceeding, had no reasonable cause to believe his conduct was unlawful and (b)
shall be indemnified by the Company against all expenses (including attorneys'
fees) and amounts paid in settlement incurred in connection with any action by
or in the right of the Company brought against him by virtue of his position as
a director or officer of the Company brought against him by virtue of his
position as a director or officer of the Company if he acted in good faith and
in a manner he reasonably believed to be in, or not opposed to, the best
interests of the Company, except that no indemnification shall be made with
respect to any matter as to which such person shall have been adjudged to be
liable to the Company, unless a court determines that, despite such adjudication
but in view of all of the circumstances, he is entitled to indemnification of
such expenses. Notwithstanding the foregoing, to the extent that a director or
officer has been successful, on the merits or otherwise, including, without
limitation, the dismissal of an action without prejudice, he is required to be
indemnified by the Company against all expenses (including attorneys' fees)
incurred in connection therewith. Expenses shall be advanced to a director or
officer at his request, provided that he undertakes to repay the amount advanced
if it is ultimately determined that he is not entitled to indemnification for
such expenses.
 
     Indemnification is required to be made unless the Company determines that
the applicable standard of conduct required for indemnification has not been
met. In the event of a determination by the Company
 
                                      II-1
<PAGE>   89
 
that the director or officer did not meet the applicable standard of conduct
required for indemnification, or if the Company fails to make an indemnification
payment within 60 days after such payment is claimed by such person, such person
is permitted to petition the court to make an independent determination as to
whether such person is entitled to indemnification. As a condition precedent to
the right of indemnification, the director or officer must give the Company
notice of the action for which indemnity is sought and the Company has the right
to participate in such action or assume the defense thereof.
 
     Section 145 of the Delaware General Corporation Law provides that a
corporation has the power to indemnify a director, officer, employee or agent of
the corporation and certain other persons serving at the request of the
corporation in related capacities against amounts paid and expenses incurred in
connection with an action or proceeding to which he is or is threatened to be
made a party by reason of such position, if such person shall have acted in good
faith and in a manner he reasonably believed to be in or not opposed to the best
interests of the corporation, and in any criminal proceeding, if such person had
no reasonable cause to believe his conduct was unlawful; provided that, in the
case of actions brought by or in the right of the corporation, no
indemnification shall be made with respect to any matter as to which such person
shall have been adjudged to be liable to the corporation unless and only to the
extent that the adjudicating court determines that such indemnification is
proper under the circumstances.
 
     Under Section 9 of the Underwriting Agreement, the Underwriters will be
obligated, under certain circumstances, to indemnify directors and officers of
the Company against certain liabilities, including liabilities under the
Securities Act.
 
ITEM 15.  RECENT SALES OF UNREGISTERED SECURITIES
 
     Set forth in chronological order below is information regarding the number
of shares of Common Stock, Class B Common Stock and Preferred Stock issued, and
the number of options granted, by the Company since June 1, 1993. Further
included is the consideration, if any, received by the Company for such shares
and options, and information relating to the section of the Securities Act, or
rule of the Securities and Exchange Commission under which exemption from
registration was claimed. All awards of options did not involve any sale under
the Securities Act and none of these securities was registered under the
Securities Act.
 
     In February 1994, the Company issued 103,351 shares of Class B Common Stock
to an executive officer in consideration of a promissory note in the initial
principal amount of $32,860, payable March 31, 1999 and bearing interest at an
annual rate of 6.0%.
 
     In November 1995, the Company issued 105,453 shares of Class B Common Stock
to an executive officer in consideration of a promissory note in the initial
principal amount of $166,865. The note matures in April 2001, bears interest at
an annual rate of 6.48% and requires bi-weekly payments of $484.34. In
connection with such issuance, the executive officer purchasing such shares
agreed to sell such shares to the Company at a price based on a formula, which
agreement expires upon completion of this Offering. Such executive officer has
pledged such shares to secure the note.
 
     In November 1995, the Company issued 883 shares of Preferred Stock to
certain investors in return for cash payment of $22 million.
 
     In March 1996, AAI awarded 105,453 shares of Class B Common Stock to 120
employees of the Company pursuant to the Company's 1995 Restricted Stock Award
Plan. Each such employee was required to pay $.001 per share in cash as
consideration for such award. Such shares vest over a period of time and
unvested shares are subject to forfeiture upon termination of employment, other
than upon the employee's death, disability or retirement.
 
     In April 1996, the Company granted options to purchase an aggregate of
450,394 shares of Class B Common Stock to 95 employees pursuant to the Company's
1995 Stock Option Plan and 1996 Stock Option Plan at an exercise price per share
of $8.35.
 
                                      II-2
<PAGE>   90
 
     The shares of capital stock and securities issued in the above transactions
were offered and sold in reliance upon the exemption from registration under
Section 4(2) of the Securities Act or Regulation D or Rule 701 promulgated under
the Securities Act, relative to sales by an issuer not involving any public
offering.
 
     Upon the completion of this Offering, the Company will issue approximately
15,434,910 shares of Common Stock upon the conversion of then outstanding shares
of Preferred Stock and Class B Common Stock. Options to purchase shares of Class
B Common Stock then outstanding will automatically become options to purchase
the same number of shares of Common Stock, with no other changes to the terms
and conditions thereof. The securities to be issued in such transactions will be
offered and sold in reliance upon the exemption from registration under Section
3(a)(9) of the Securities Act.

ITEM 17.  UNDERTAKINGS
 
     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the Company
pursuant to the provisions contained in the Restated Certificate of
Incorporation and Restated By-laws of the Company and the laws of the State of
Delaware, or otherwise, the Company has been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public policy
as expressed in the Securities Act and is, therefore, unenforceable. In the
event that a claim for indemnification against such liabilities (other than the
payment by the Company of expenses incurred or paid by a director, officer or
controlling person of the Company in the successful defense of any action, suit
or proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Company 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 Company 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.
 
     The undersigned Company hereby undertakes that:
 
          (1) For purposes of determining any liability 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
     a form of prospectus filed by the Company 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.

<PAGE>   2

         The following is a statement of the designations and the powers,
privileges and rights, and the qualifications, limitations or restrictions
thereof in respect of each class of capital stock of the Corporation.

A.       COMMON STOCK

         1.      General.  The voting, dividend and liquidation rights of the
holders of the Common Stock are subject to and qualified by the rights of the
holders of the Preferred Stock of any series as may be designated by the Board
of Directors upon any issuance of the Preferred Stock of any series.

         2.      Voting.  The holders of the Common Stock are entitled to one
vote for each share held at all meetings of stockholders (and written actions
in lieu of meetings).  There shall be no cumulative voting.

         The number of authorized shares of Common Stock may be increased or
decreased (but not below the number of shares thereof then outstanding) by the
affirmative vote of the holders of a majority of the stock of the Corporation
entitled to vote, irrespective of the provisions of Section 242(b)(2) of the
General Corporation Law.

         3.      Dividends.  Dividends may be declared and paid on the Common
Stock from funds lawfully available therefor as and when determined by the
Board of Directors and subject to any preferential dividend rights of any then
outstanding Preferred Stock.

         4.      Liquidation.  Upon the dissolution or liquidation of the
Corporation, whether voluntary or involuntary, holders of Common Stock will be
entitled to receive all assets of the Corporation available for distribution to
its stockholders, subject to any preferential rights of any then outstanding
Preferred Stock.

B.       PREFERRED STOCK.

         Preferred Stock may be issued from time to time in one or more series,
each of such series to have such terms as stated or expressed herein and in the
resolution or resolutions providing for the issue of such series adopted by the
Board of Directors of the Corporation as hereinafter provided.  Any shares of
Preferred Stock that may be redeemed, purchased or acquired by the Corporation
may be reissued except as otherwise provided by law or this Certificate of
Incorporation.  Different series of Preferred Stock shall not be construed to
constitute different classes of shares for the purposes of voting by classes
unless expressly provided.

         Authority is hereby expressly granted to the Board of Directors from
time to time to issue the Preferred Stock in one or more series, and in
connection with the creation of any such series, by resolution or resolutions
providing for the issue of the shares thereof, to determine and fix such voting
powers, full or limited, or no voting powers, and such designations,
preferences and relative participating, optional or other special rights, and
qualifications, limitations or restrictions thereof, including without
limitation, dividend rights, conversion rights, redemption privileges and
liquidation preferences, as shall be stated and expressed in such resolutions,
all to the full extent now or hereafter permitted by the General Corporation
Law.  Without limiting the generality of the foregoing, the resolutions
providing for issuance of any series of Preferred Stock may provide that such
series shall be superior or rank equally or be junior to the Preferred Stock of
any other series to the extent permitted





                                      -2-
<PAGE>   3


by law and this Certificate of Incorporation.  Except as otherwise provided in
this Certificate of Incorporation, no vote of the holders of the Preferred
Stock or Common Stock shall be a prerequisite to the designation or issuance of
any shares of any series of the Preferred Stock authorized by and complying
with the conditions of this Certificate of Incorporation, the right to have
such vote being expressly waived by all present and future holders of the
capital stock of the Corporation.

         FIFTH.  The Corporation shall have a perpetual existence.

         SIXTH.  In furtherance of and not in limitation of powers conferred by
statute, the board of directors is expressly authorized to adopt, amend or
repeal the by-laws of the Corporation.

         SEVENTH.  Whenever a compromise or arrangement is proposed between
this Corporation and its creditors or any class of them and/or between this
Corporation and its stockholders or any class of them, any court of equitable
jurisdiction within the State of Delaware may, on the application in a summary
way of this Corporation or of any creditor or stockholder thereof, or on the
application of any receiver or receivers appointed for this Corporation under
the provisions of Section 291 of Title 8 of the Delaware Code or on the
application of trustees in dissolution or of any receiver or receivers
appointed for this Corporation under the provisions of section 279 of Title 8
of the Delaware Code order a meeting of the creditors or class of creditors,
and/or of the stockholders or class of stockholders of this Corporation, as the
case may be, to be summoned in such manner as the said court directs.  If a
majority in number representing three-fourths in value of the creditors or
class of creditors, and/or of the stockholders or class of stockholders of this
Corporation, as the case may be, agree to any compromise or arrangement and to
any reorganization of this Corporation as a consequence of such compromise or
arrangement, the said compromise or arrangement and the said reorganization
shall, if sanctioned by the court to which the said application has been made,
be binding on all the creditors or class of creditors, and/or on all the
stockholders or class of stockholders, of this Corporation, as the case may be,
and also on this Corporation.

         EIGHTH.  Except to the extent that the General Corporation Law
prohibits the elimination or limitation of liability of directors for breaches
of fiduciary duty, no director of the Corporation shall be personally liable to
the Corporation or its stockholders for monetary damages for any breach of
fiduciary duty as a director, notwithstanding any other provision of law
imposing such liability.  No amendment to or repeal of this provision shall
apply to or have any effect on the liability or alleged liability of any
director of the Corporation for or with respect to any acts or omissions of
such director occurring prior to such amendment.

         NINTH.  The Corporation reserves the right to amend, alter, change or
repeal any provision contained in this Restated Certificate of Incorporation,
in the manner now or hereafter prescribed by statute and this Restated
Certificate of Incorporation, and all rights conferred upon stockholders herein
are granted subject to this reservation.

         TENTH:  This Article is inserted for the management of the business
and for the conduct of the affairs of the Corporation.

         1.      Number of Directors.  The number of directors of the
Corporation shall not be less than three (3) nor more than seven (7).  The
exact number of directors within the limitations specified in the preceding
sentence shall be fixed from time to time by, or in the manner provided in, the
Corporation's By-Laws.





                                      -3-
<PAGE>   4


         2.      Classes of Directors.  The Board of Directors shall be and is
divided into three classes:  Class I, Class II and Class III.  No one class
shall have more than one director more than any other class.  If a fraction is
contained in the quotient arrived at by dividing the designated number of
directors by three, then, if such fraction is one-third, the extra director
shall be a member of Class I, and if such fraction is two-thirds, one of the
extra directors shall be a member of Class I and one of the extra directors
shall be a member of Class II, unless otherwise provided from time to time by
resolution adopted by the Board of Directors.

   3.      Election of Directors.  Elections of directors must be by written
ballot.

         4.      Terms of Office.  Each director shall serve for a term ending
on the date of the third annual meeting following the annual meeting at which
such director was elected; provided, that each initial director in Class I
shall serve for a term ending on the date of the annual meeting in 1997; each
initial director in Class II shall serve for a term ending on the date of the
annual meeting in 1998; and each initial director in Class III shall serve for
a term ending on the date of the annual meeting in 1999; and provided further,
that the term of each director shall be subject to the election and
qualification of his successor and to his earlier death, resignation or
removal.

         5.      Allocation of Directors Among Classes in the Event of
Increases or Decreases in the Number of Directors.  In the event of any
increase or decrease in the authorized number of directors, (i) each director
then serving as such shall nevertheless continue as a director of the class of
which he is a member and (ii) the newly created or eliminated directorships
resulting from such increase or decrease shall be apportioned by the Board of
Directors among the three classes of directors so as to ensure that no one
class has more than one director more than any other class.  To the extent
possible, consistent with the foregoing rule, any newly created directorships
shall be added to those classes whose terms of office are to expire at the
latest dates following such allocation, and any newly eliminated directorships
shall be subtracted from those classes whose terms of offices are to expire at
the earliest dates following such allocation, unless otherwise provided from
time to time by resolution adopted by the Board of Directors.

         6.      Quorum; Action at Meeting.  A majority of the directors at any
time in office shall constitute a quorum for the transaction of business.  In
the event one or more of the directors shall be disqualified to vote at any
meeting, then the required quorum shall be reduced by one for each director so
disqualified, provided that in no case shall less than one-third of the number
of directors fixed pursuant to Section 1 above constitute a quorum.  If at any
meeting of the Board of Directors there shall be less than such a quorum, a
majority of those present may adjourn the meeting from time to time.  Every act
or decision done or made by a majority of the directors present at a meeting
duly held at which a quorum is present shall be regarded as the act of the
Board of Directors unless a greater number is required by law, by the By-Laws
of the Corporation or by this Restated Certificate of Incorporation.

         7.      Resignation; Removal.  Any director may resign at any time
upon written notice to the attention of the secretary of the corporation.
Directors of the Corporation may be removed only for cause by the affirmative
vote of the holders of at least two-thirds of the shares of the capital stock
of the Corporation issued and outstanding and entitled to vote.

         8.      Vacancies.  Any vacancy in the Board of Directors, however
occurring, including a vacancy resulting from an enlargement of the board,
shall be filled only by a vote of a majority of the directors then in office,
although less than a quorum, or by a sole remaining director.  A director
elected





                                      -4-
<PAGE>   5


to fill a vacancy shall be elected to hold office until the next election of
the class for which such director shall have been chosen, subject to the
election and qualification of his successor and to his earlier death,
resignation or removal.

         9.      Amendments to Article.  Notwithstanding any other provisions
of law, this Restated Certificate of Incorporation or the By-Laws of the
Corporation, each as amended, and notwithstanding the fact that a lesser
percentage may be specified by law, the affirmative vote of the holders of at
least seventy-five percent (75%) of the shares of capital stock of the
Corporation issued and outstanding and entitled to vote shall be required to
amend or repeal, or to adopt any provision inconsistent with, this Article
TENTH.

         ELEVENTH.  Stockholders of the Corporation may not take any action by
written consent in lieu of a meeting.  Notwithstanding any other provisions of
law, this Restated Certificate of Incorporation or the By-Laws of the
Corporation, each as amended, and notwithstanding the fact that a lesser
percentage may be specified by law, the affirmative vote of the holders of at
least seventy-five percent (75%) of the shares of capital stock of the
Corporation issued and outstanding and entitled to vote shall be required to
amend or repeal, or to adopt any provision inconsistent with, this Article
ELEVENTH.

         TWELFTH.  Special meetings of stockholders may be called at any time
by (and only by) the Board of Directors.  Business transacted at any special
meeting of stockholders shall be limited to matters relating to the purpose or
purposes stated in the notice of meeting.  Notwithstanding any other provision
of law, this Restated Certificate of Incorporation or the By-Laws of the
Corporation, each as amended, and notwithstanding the fact that a lesser
percentage may be specified by law, the affirmative vote of the holders of at
least seventy-five percent (75%) of the shares of capital stock of the
Corporation issued and outstanding and entitled to vote shall be required to
amend or repeal, or to adopt any provisions inconsistent with, this Article
TWELFTH.

         THIRTEENTH.  In anticipation that the Corporation may enter into
contracts or otherwise transact business with entities in which any directors
of the Corporation own a financial interest ("Related Entities"), the
provisions of this Article THIRTEENTH are set forth to regulate and guide such
contracts or other business.  These provisions are in addition to, and not in
limitation of, the provisions of the General Corporation Law and the other
provisions of this Restated Certificate of Incorporation.  Any contract or
other business that does not comply with the procedures set forth in this
Article THIRTEENTH shall not by reason thereof be deemed void or voidable or
result in any breach of any duty or the derivation of any improper personal
benefit by any person but shall be governed by the provisions of this Restated
Certificate of Incorporation, the By-laws of the Corporation, the General
Corporation Law and other applicable law.

         No contract, agreement, arrangement or transaction between the
Corporation and a Related Entity (a "Related Transaction") shall be void or
voidable solely for the reason that such persons or entities are parties
thereto, if:

         (i)     the material facts of the Related Transaction are disclosed or
                 are known to the Board of Directors of the Corporation (or a
                 committee thereof) and such board (or committee) in good faith
                 authorizes, approves or ratifies the Related Transaction by
                 the affirmative vote of a majority of the disinterested
                 directors on the Board of Directors (or such committee), even
                 though the disinterested directors may be less than a quorum;





                                      -5-
<PAGE>   6


         (ii)    the material facts of the Related Transaction are disclosed or
                 are known to the holders of the then outstanding voting shares
                 of the Corporation entitled to vote thereon, and the Related
                 Transaction is specifically approved or ratified in good faith
                 by the affirmative vote of the holders of a majority of the
                 then outstanding voting shares not owned by the interested
                 directors or Related Entity, as the case may be, even though
                 such holders may be less than a quorum;

         (iii)   such Related Transaction is effected pursuant to and
                 consistent with terms and conditions specified in any
                 arrangements, standards or guidelines that are in good faith
                 authorized, approved or ratified, after disclosure or
                 knowledge of the material facts related thereto, by the
                 affirmative vote of a majority of the disinterested directors
                 on the Board of Directors (or committee thereof), or by the
                 affirmative vote of the holders of a majority of the then
                 outstanding voting shares of the Corporation not owned by the
                 interested directors or Related Entity, as the case may be,
                 even though the disinterested directors or such holders may be
                 less than a quorum; or

         (iv)    The Related Transaction was fair to the Company.

         In addition, each Related Transaction authorized, approved or
effected, and each of such arrangements, standards or guidelines so authorized
or approved, as described in (i), (ii) or (iii) above, shall be conclusively
deemed to be fair to the Corporation and its stockholders; provided, however,
that if such authorization or approval is not obtained, or such Related
Transaction is not so effected, no presumption shall arise that such Related
Transaction, or such arrangements, standards or guidelines, are not fair to the
Corporation and its stockholders.

         Any person or entity purchasing or otherwise acquiring any interest in
any shares of the Corporation shall be deemed to have notice of and to have
consented to the provisions of this Article THIRTEENTH.

         IN WITNESS WHEREOF, the Corporation has caused its corporate seal to
be affixed hereto and this Restated Certificate of Incorporation to be signed
by its President this ______th day of ____________, 1996.

place or places where the corporation is qualified to do business.

                                   ARTICLE II

                            MEETINGS OF STOCKHOLDERS

         2.1     PLACE OF MEETINGS

         Meetings of stockholders shall be held at any place, within or outside
the State of Delaware, designated by the board of directors.  In the absence of
any such designation, stockholders' meetings shall be held at the registered
office of the corporation.

         2.2     ANNUAL MEETING

         The annual meeting of stockholders shall be held each year on a date
and at a time designated by the board of directors.  In the absence of such
designation, the annual meeting of stockholders shall be held on the second
Monday of May of each year at 10:00 a.m.  However, if such day falls on a legal
holiday, then the meeting shall be held at the same time and place on the next
succeeding business day.  At the meeting, directors shall be elected and any
other proper business may be transacted.

         2.3     SPECIAL MEETINGS

         Special meetings of the stockholders may be called only by the board
of directors as permitted in the certificate of incorporation (All references
to "certificate of incorporation" herein shall be references to the certificate
of incorporation as amended, supplemented or restated from time to time).  The
corporation shall promptly give notice to the stockholders entitled to vote
upon the calling of a special meeting in accordance with the provisions of
SECTIONS 2.4 AND 2.5 hereof.


<PAGE>   6

         2.4     NOTICE OF STOCKHOLDERS' MEETINGS

         All notices of meetings with stockholders shall be in writing and
shall be sent or otherwise given in accordance with SECTION 2.5 of these
by-laws not less than ten (10) nor more than sixty (60) days before the date of
the meeting to each stockholder entitled to vote at such meeting.  The notice
shall specify the place, date, and hour of the meeting, and, in the case of a
special meeting, the purpose or purposes for which the meeting is called.

         2.5     MANNER OF GIVING NOTICE; AFFIDAVIT OF NOTICE

         Written notice of any meeting of stockholders, if mailed, is given
when deposited in the United States mail, postage prepaid, directed to the
stockholder at his address as it appears on the records of the corporation.  An
affidavit of the Secretary or an Assistant Secretary or of the transfer agent
of the corporation that the notice has been given shall, in the absence of
fraud, be prima facie evidence of the facts stated therein.

         2.6     QUORUM

         The holders of a majority of the stock issued and outstanding and
entitled to vote thereat, present in person or represented by proxy, shall
constitute a quorum at all meetings of the stockholders for the transaction of
business except as otherwise provided by statute or by the certificate of
incorporation.  If, however, such quorum is not present or represented at any
meeting of the stockholders, then either (i) the Chairman of the meeting or
(ii) the stockholders entitled to vote thereat, present in person or
represented by proxy, shall have power to adjourn the meeting from time to
time, without notice other than announcement at the meeting, until a quorum is
present or represented.  At such adjourned meeting at which a quorum is present
or represented, any business may be transacted that might have been transacted
at the meeting as originally noticed.

         2.7     ADJOURNED MEETING; NOTICE

         When a meeting is adjourned to another time or place, unless these
by-laws otherwise require, notice need not be given of that adjourned meeting
if the time and place thereof are announced at the meeting at which the
adjournment is taken.  At the adjourned meeting the corporation may transact
any business that might have been transacted at the original meeting.  If the
adjournment is for more than thirty (30) days, or if after the adjournment a
new record date is fixed for the adjourned meeting, a notice of the adjourned
meeting shall be given to each stockholder of record entitled to vote at the
meeting.

         2.8     CONDUCT OF BUSINESS

         Subject to any other applicable requirements, only such business
(including the nomination of a person for election as a director) may be
conducted at a meeting of the stockholders as has been brought before the
meeting by, or at the direction of, the corporation's board of directors or by
a stockholder who has given to the secretary of the corporation timely written
notice, as provided below, of the stockholder's intention to bring certain
business before the meeting.

         Any stockholder wishing to bring business before a meeting of
stockholders must provide notice to the corporation not more than one hundred
twenty (120) days in advance of the anniversary date of the corporation's proxy
statement for the previous year's annual meeting or, in the case of special



                                     -2-

<PAGE>   7


meetings, at the close of business on the tenth (10th) day following the date
on which notice of such meeting is first given to stockholders, of the business
to be presented by him at the stockholders' meeting.  Any such notice shall set
forth the following as to each matter the stockholder proposes to bring before
the meeting:  (A) a brief description of the business desired to be brought
before the meeting and the reasons for conducting such business at the meeting
and, if such business includes a proposal to amend the by-laws of the
corporation, the language of the proposed amendment; (B) the name and address,
as they appear (if so appearing) on the corporation's books, of the stockholder
proposing such business (and any person acting in concert with such
stockholder); (C) the class and number of shares of the corporation that are
beneficially owned by such stockholder; (D) a representation that the
stockholder is a holder of record of stock of the corporation entitled to vote
at such meeting and intends to appear in person or by proxy at the meeting to
propose such business; and (E) any material interest of the stockholder in such
business.  Notwithstanding the foregoing provisions of this Section, a
stockholder shall also comply with all applicable requirements of the
Securities Exchange Act of 1934, as amended, and the rules and regulations
thereunder with respect to the matters set forth in this Section.  In the
absence of such notice to the corporation meeting the above requirements, a
stockholder shall not be entitled to present any business at any meeting of
stockholders.

         The presiding officer of any meeting of stockholders shall determine
the order of business and the procedure at the meeting, including the
regulation of the manner of voting and the conduct of business.

         2.9     VOTING

         The stockholders entitled to vote at any meeting of stockholders shall
be determined in accordance with the provisions of SECTION 2.12 of these
by-laws, subject to the provisions of Sections 217 and 218 of the General
Corporation Law of Delaware (relating to voting rights of fiduciaries, pledgers
and joint owners of stock and to voting trusts and other voting agreements).

         Except as may be otherwise provided in the certificate of
incorporation, each stockholder shall be entitled to one vote for each share of
capital stock held by such stockholder.

         2.10    WAIVER OF NOTICE

         Whenever notice is required to be given under any provision of the
General Corporation Law of Delaware or of the certificate of incorporation or
these by-laws, a written waiver thereof, signed by the person entitled to
notice, whether before or after the time stated therein, shall be deemed
equivalent to notice.  Attendance of a person at a meeting shall constitute a
waiver of notice of such meeting, except when the person attends a meeting for
the express purpose of objecting, at the beginning of the meeting, to the
transaction of any business because the meeting is not lawfully called or
convened.  Neither the business to be transacted at, nor the purpose of, any
regular or special meeting of the stockholders need be specified in any written
waiver of notice unless so required by the certificate of incorporation or
these by-laws.

         2.11    STOCKHOLDER ACTION BY WRITTEN CONSENT WITHOUT A MEETING

         Unless otherwise provided in the certificate of incorporation, any
action required by this chapter to be taken at any annual or special meeting of
stockholders of a corporation, or any action that may be taken at any annual or
special meeting of such stockholders, may be taken without a meeting, without



                                     -3-

<PAGE>   8


prior notice, and without a vote if a consent in writing, setting forth the
action so taken, is signed by the holders of outstanding stock having not less
than the minimum number of votes that would be necessary to authorize or take
such action at a meeting at which all shares entitled to vote thereon were
present and voted.

         Prompt notice of the taking of the corporate action without a meeting
by less than unanimous written consent shall be given to those stockholders who
have not consented in writing.  If the action that is consented to would have
required the filing of a certificate under any section of the General
Corporation Law of Delaware if such action had been voted on by stockholders at
a meeting thereof, then the certificate filed under such section shall state,
in lieu of any statement required by such section concerning any vote of
stockholders, that written notice and written consent have been given as
provided in Section 228 of the General Corporation Law of Delaware.

         2.12    RECORD DATE FOR STOCKHOLDER NOTICE; VOTING; GIVING CONSENTS

         In order that the corporation may determine the stockholders entitled
to notice of or to vote at any meeting of stockholders or any adjournment
thereof, or entitled to express consent to corporation action in writing
without a meeting, or entitled to receive payment of any dividend or other
distribution or allotment of any rights, or entitled to exercise any rights in
respect of any change, conversion or exchange or stock or for the purpose of
any other lawful action, the board of directors may fix, in advance, a record
date, which shall not be more than sixty (60) nor less than ten (10) days
before the date of such meeting, nor more than sixty (60) days prior to any
other action.

         If the board of directors does not so fix a record date:

         (i)     The record date for determining stockholders entitled to
notice of or to vote at a meeting of stockholders shall be at the close of
business on the day next preceding the day on which notice is given, or, if
notice is waived, at the close of business on the day next preceding the day on
which the meeting is held.

         (ii)    The record date for determining stockholders entitled to
express consent to corporate action in writing without a meeting, when no prior
action by the board of directors is necessary, shall be the day on which the
first written consent is expressed.

         (iii)   The record date for determining stockholders for any other
purpose shall be at the close of business on the day on which the board of
directors adopts the resolution relating thereto.

         A determination of stockholders of record entitled to notice of or to
vote at a meeting of stockholders shall apply to any adjournment of the
meeting; provided, however, that the board of directors may fix a new record
date for the adjourned meeting.

         2.13    PROXIES

         Each stockholder entitled to vote at a meeting of stockholders or to
express consent or dissent to corporate action in writing without a meeting may
authorize another person or persons to act for him by a written proxy, signed
by the stockholder and filed with the secretary of the corporation, but no such
proxy shall be voted or acted upon after three (3) years from its date, unless
the proxy provides for a longer period.  A proxy shall be deemed signed if the
stockholder's name is placed on the proxy (whether


                                     -4-


<PAGE>   9


by manual signature, typewriting, telegraphic transmission or otherwise) by the
stockholder or the stockholder's attorney-in-fact.  The revocability of a proxy
that states on its face that it is irrevocable shall be governed by the
provisions of Section 212(c) of the General Corporation Law of Delaware.

         2.14    LIST OF STOCKHOLDERS ENTITLED TO VOTE

         The officer who has charge of the stock ledger of a corporation shall
prepare and make, at least ten (10) days before every meeting of stockholders,
a complete list of the stockholders entitled to vote at the meeting, arranged
in alphabetical order, and showing the address of each stockholder and the
number of shares registered in the name of each stockholder.  Such list shall
be open to the examination of any stockholder, for any purpose germane to the
meeting, during ordinary business hours, for a period of at least ten (10) days
prior to the meeting, either at a place within the city where the meeting is to
be held, which place shall be specified in the notice of the meeting, or, if
not so specified, at the place where the meeting is to be held.  The list shall
also be produced and kept at the time and place of the meeting during the whole
time thereof, and may be inspected by any stockholder who is present.  Such
list shall presumptively determine the identity of the stockholders entitled to
vote at the meeting and the number of shares held by each of them.

         3.3     ELECTION OF DIRECTORS

         The board of directors of the corporation may hold meetings, both
regular and special, either within or outside the State of Delaware.  Unless
otherwise restricted by the certificate of incorporation or these by-laws,
members of the board of directors, or any committee designated by the board of
directors, may participate in a meeting of the board of directors, or any
committee, by means of conference telephone or similar communications equipment
by means of which all persons participating in the meeting can hear each other,
and such participation in a meeting shall constitute presence in person at the
meeting.

         3.5     REGULAR MEETINGS

         Regular meetings of the board of directors may be held without notice
at such time and at such place as shall from time to time be determined by the

         Special meetings of the board of directors for any purpose or purposes
may be called at any time by the chairman of the board, the president, any vice
president, the secretary or any two (2) directors.

         Notice of the time and place of special meetings shall be delivered
personally or by telephone to each director or sent by first-class mail or
telegram, charges prepaid, addressed to each director at that director's
address as it is shown on the records of the corporation.  If the notice is
mailed, it shall be deposited in the United States mail at least four (4) days
before the time of the holding of the meeting.  If the notice is delivered
personally or by telephone or by telegram, it shall be delivered personally or
by telephone or to the telegraph company at least forty- eight (48) hours

General Corporation Law of Delaware or of the certificate of incorporation or
these by-laws, a written waiver thereof, signed by the person entitled to
notice, whether before or after the time stated therein, shall be deemed
equivalent to notice.  Attendance of a person at a meeting shall constitute a
waiver of notice of such meeting, except when the person attends a meeting for
the express purpose of objecting, at the beginning of the meeting, to the
transaction of any business because the meeting is not lawfully called or
convened.  Neither the business to be transacted at, nor the purpose of, any
regular or special meeting of the directors, or members of a committee of
directors, need be specified in any written waiver of notice unless so required
by the certificate of incorporation or these by-laws.

         3.8     BOARD ACTION BY WRITTEN CONSENT WITHOUT A MEETING

meeting if all members of the board or committee, as the case may be, consent
thereto in writing and the writings are filed with the minutes of proceedings
of the board or committee.

interest and may be unsecured, or secured in such manner as the board of
directors shall approve, including, without limitation, a pledge of share of
stock of the corporation.  Nothing in this section contained shall be deemed to
deny, limit or restrict the powers of guaranty or warranty of the corporation
at common law or under any statute.

thereof present at any meeting and not disqualified from voting, whether or not
he or they constitute a quorum, may unanimously appoint another member of the
board of directors to act at the meeting in the place of any such absent or
disqualified member.  Any such committee, to the extent provided in the
resolution of the board of directors or in the by-laws of the corporation,
shall have and may exercise all the powers and authority of the board of
directors in the management of the business and affairs of the corporation, and
may authorize the seal of the corporation to be affixed to all papers that may
require it; but no such committee shall have the power or authority to (i)

151(a) of the General Corporation Law of Delaware, fix the designations and any
of the preferences or rights of such shares relating to dividends, redemption,

into, or the exchange of such shares for, shares of any other class or classes

         Meetings and actions of committees shall be governed by, and held and
taken in accordance with, the provisions of these by-laws and the certificate
of incorporation with such changes in the context thereof as are necessary to
substitute the committee and its members for the board of directors and its
members; provided, however, that the time of regular meetings of committees may
be determined either by resolution of the board of directors or by resolution
of the committee, that special meetings of committees may also be called by
resolution of the board of directors and that notice of special meetings of
committees shall also be given to all alternate members, who shall have the
right to attend all meetings of the committee.  The board of directors may

on behalf of this corporation all rights incident to any and all shares of any
other corporation or corporations standing in the name of this corporation.
The authority granted herein may be exercised either by such person directly or
by any other person authorized to do so by proxy or power of attorney duly
executed by such person having the authority.

         5.13    AUTHORITY AND DUTIES OF OFFICERS

         In addition to the foregoing authority and duties, all officers of the
corporation shall respectively have such authority and perform such duties in
the management of the business of the corporation as may be designated from

                                   ARTICLE VI

                                   INDEMNITY

         6.1     THIRD PARTY ACTIONS

         The corporation shall indemnify any person who was or is a party or is
threatened to be made a party to any threatened, pending, or completed action,
suit or proceeding, whether civil, criminal, administrative or investigative
(other than an action by or in the right of the corporation) by reason of the
fact that he is or was a director, officer, employee or agent of the
corporation, or is or was serving at the request of the corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture trust or other enterprise, against expenses (including attorneys'
fees), judgments, fines and amounts paid in settlement (if such settlement is
approved in advance by the corporation, which approval shall not be
unreasonably withheld) actually and reasonably incurred by him in connection
with such action, suit or proceeding if he acted in good faith and in a manner
he reasonably believed to be in or not opposed to the best interests of the
corporation, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful.  The termination of any
action, suit or proceeding by judgment, order, settlement, conviction, or upon
a plea of nolo contendere or its equivalent, shall not, of itself, create a
presumption that the person did not act in good faith and in a manner which he
reasonably believed to be in or not opposed to the best interest of the
corporation, and, with respect to any criminal action or proceeding, had
reasonable cause to believe that his conduct was unlawful.

         6.2     ACTIONS BY OR IN THE RIGHT OF THE CORPORATION

         The corporation shall indemnify any person who was or is a party or is
threatened to be made a party to any threatened, pending or completed action or
suit by or in the right of the corporation to procure a judgment in its favor
by reason of the fact that he is or was a director, officer, employee or agent
of corporation, or is or was serving at the request of the corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise against expenses (including attorneys' fees)
and amounts paid in settlement (if such settlement is approved in



                                     -11-

<PAGE>   16

advance by the corporation, which approval shall not be unreasonably withheld)
actually and reasonably incurred by him in connection with the defense or
settlement of such action or suit if he acted in good faith and in manner he
reasonably believed to be in or not opposed to the best interests of the
corporation, except that no indemnification shall be made in respect of any
claim, issue or matter as to which such person shall have been adjudged to be
liable to the corporation unless and only to the extent that the Delaware Court
of Chancery or the court in which such action or suit was brought shall
determine upon application that, despite the adjudication of liability but in
view of all the circumstances of the case, such person is fairly and reasonably
entitled to indemnity for such expenses which the Delaware Court of Chancery or
such other court shall deem proper.  Notwithstanding any other provision of
this ARTICLE VI, no person shall be indemnified hereunder for any expenses or
amounts paid in settlement with respect to any action to recover short-swing
profits under Section 16(b) of the Securities Exchange Act of 1934, as amended.

         6.3     SUCCESSFUL DEFENSE

         To the extent that a director, officer, employee or agent of the
corporation has been successful on the merits or otherwise in defense of any
action, suit or proceeding referred to in SECTIONS 6.1 AND 6.2, or in defense
of any claim, issue or matter therein, he shall be indemnified against expenses
(including attorneys' fees) actually and reasonably incurred by him in
connection therewith.

         6.4     DETERMINATION OF CONDUCT

         Any indemnification under SECTIONS 6.1 AND 6.2 (unless ordered by a
court) shall be made by the corporation only as authorized in the specific case
upon a determination that the indemnification of the director, officer,
employee or agent is proper in the circumstances because he has met the
applicable standard of conduct set forth in SECTIONS 6.1 AND 6.2.  Such
determination shall be made (a) by the board of directors by a majority vote of
a quorum consisting of directors who were not parties to such action, suit or
proceeding or (b) or if such quorum is not obtainable or, even if obtainable, a
quorum of disinterested directors so directs, by independent legal counsel in a
written opinion, or (c) by the stockholders.  Notwithstanding the foregoing, a
director, officer, employee or agent of the corporation shall be entitled to
contest any determination that the director, officer, employee or agent has not
met the applicable standard of conduct set forth in SECTIONS 6.1 AND 6.2 by
petitioning a court of competent jurisdiction.

         6.5     PAYMENT OF EXPENSES IN ADVANCE

         Expenses incurred in defending a civil or criminal action, suit or
proceeding, by an individual who may be entitled to indemnification pursuant to
SECTION 6.1 OR 6.2, shall be paid by the corporation in advance of the final
disposition of such action, suit or proceeding upon receipt of an undertaking
by or on behalf of the director, officer, employee or agent to repay such
amount if it shall ultimately be determined that he is not entitled to be
indemnified by the corporation as authorized in this ARTICLE VI.

         6.6     INDEMNITY NOT EXCLUSIVE

         The indemnification and advancement of expenses provided by or granted
pursuant to the other sections of this ARTICLE VI shall not be deemed exclusive
of any other rights to which those seeking indemnification or advancement of
expenses may be entitled under any by-law, agreement, vote of



                                     -12-

<PAGE>   17


stockholders or disinterested directors or otherwise, both as to action in such
persons' official capacity and as to action in another capacity while holding
such office.

         6.7     INSURANCE INDEMNIFICATION

         The corporation shall have the power to purchase and maintain
insurance on behalf of any person who is or was a director, officer, employee
or agent of the corporation, or is or was serving at the request of the
corporation as a director, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise, against any liability
asserted against him and incurred by him in any such capacity or arising out of
his status as such, whether or not the corporation would have the power to

         7.1     MAINTENANCE AND INSPECTION OF RECORDS

         The corporation shall, either at its principal executive officer or at
such place or places as designated by the board of directors, keep a record of
its stockholders listing their names and addresses and the number and class of
shares held by each stockholder, a copy of these by-laws as amended to date,
accounting books, and other records.

         Any stockholder of record, in person or by attorney or other agent,
shall, upon written demand under oath stating the purpose thereof, have the
right during the usual hours for business to inspect for any proper purpose the
corporation's stock ledger, a list of its stockholders, and its other books and
records and to make copies or extracts therefrom.  A proper purpose shall mean
a purpose reasonably related to such person's interest as a stockholder.  In
every instance where an attorney or other agent is the person who seeks the
right to inspection, the demand under oath shall be accompanied by a power of
attorney or such other writing that authorizes the attorney or other agent to
so act on behalf of the stockholder.  The demand under oath shall be directed
to the corporation at its registered office in Delaware or at its principal
place of business.

         The officer who has charge of the stock ledger of the corporation
shall prepare and make, at least ten (10) days before every meeting of
stockholders, a complete list of the stockholders entitled to vote at the
meeting, arranged in alphabetical order, showing the address of each
stockholder and the number of shares registered in the name of each
stockholder.  Such list shall be open to the examination of any stockholder,
for any purpose germane to the meeting, during ordinary business hours, for a
period of at least ten (10) days prior to the meeting, either at a place within
the city where the meeting is to be held, which place shall be specified in the
notice of the meeting, or, if not so specified, at the place where the meeting
is to be held.  The list shall also be produced and kept at the time and place
of the meeting during the whole time thereof, an may be inspected by any
stockholder who is present.

         7.2     INSPECTION BY DIRECTORS

         Any director shall have the right to examine the corporation's stock
ledger, a list of its stockholders, and its other books and records for a
purpose reasonably related to his position as a director.  The Court of
Chancery in Delaware is hereby vested with the exclusive jurisdiction to
determine whether a director is entitled to the inspection sought.  The Court
may summarily order the corporation to permit the director to inspect any and
all books and records, the stock ledger, and the stock list and to make copies
or extracts therefrom.  The Court may, in its discretion, prescribe any
limitations or conditions with reference to the inspection, or award such other
and further relief as the Court may deem just and proper.

         7.3     ANNUAL STATEMENT TO STOCKHOLDERS

         The board of directors shall present at each annual meeting, and at
any special meeting of the stockholders when called for by vote of the
stockholders, a full and clear statement of the business and condition of the

         8.1     CHECKS

         From time to time, the board of directors shall determine by
resolution which person or person may sign or endorse all checks, drafts, other
orders for payment of money, notes or other evidences of indebtedness that are
issued in the name of or payable to the corporation, and other the persons so
authorized shall sign or endorse those instruments.

         8.2     EXECUTION OF CORPORATE CONTRACTS AND INSTRUMENTS

         The board of directors, except as otherwise provided in these by-laws,
may authorize any officer or officers, or agent or agents, to enter into any
contract or execute any instrument in the name of and on behalf of the
corporation; such authority may be general or confined to specific instances.
Unless so authorized or ratified by the board of directors or within the agency
power of an officer, no officer, agent or employee shall have any power or
authority to bind the corporation by any contract or engagement or to pledge
its credit or to render it liable for any purpose or for any amount.

         8.3     STOCK CERTIFICATES; PARTLY PAID SHARES

         The shares of the corporation shall be represented by certificates,
provided that the board of directors of the corporation may provide by
resolution or resolutions that some or all of any or all classes or series of
its stock shall be uncertificated shares.  Any such resolution shall not apply
to shares represented by a certificate until such certificate is surrendered to
the corporation.  Notwithstanding the adoption of such a resolution by the
board of directors, every holder of stock represented by certificates and upon
request every holder of uncertificated shares shall be entitled to have a
certificate signed by, or in the name of the corporation by the chairman or
vice-chairman of the board of directors, or the president or vice president,
and by the chief financial officer or an assistant treasurer, or the secretary
or an assistant secretary of such corporation representing the number of shares
registered in certificate form.  Any or all of the signatures on the
certificate may be a facsimile.  In case any officer, transfer agent or
registrar who has signed or whose facsimile signature has been placed upon a
certificate has ceased to be such officer, transfer agent or registrar before
such certificate is issued, it may be issued by the corporation with the same
effect as if he were such officer, transfer agent or registrar at the date of
issue.

         The corporation may issue the whole or any part of its shares as
partly paid and subject to call for the remainder of the consideration to be
paid therefor.  Upon the face or back of each stock certificate issued to
represent any such partly paid shares, upon the books and records of the
corporation in the case of uncertificated partly paid shares, the total amount
of the consideration to be paid therefor and the amount paid thereon shall be
stated.  Upon the declaration of any dividend on fully paid shares, the
corporation shall declare a dividend upon partly paid shares of the same class,
but only upon the basis of the percentage of the consideration actually paid
thereon.

preferences, and the relative, participating, optional or other special rights
of each class of stock or series thereof and the qualifications, limitations or
restrictions of such preferences and/or rights shall be set forth in full or

any certificate previously issued by it, alleged to have been lost, stolen or
destroyed, and the corporation may require the owner of the lost, stolen or
destroyed certificate, or his legal representative, to give the corporation a
bond sufficient to indemnify it against any claim that may be made against it
on account of the alleged loss, theft or destruction of any such certificate or
the issuance of such new certificate or uncertificated shares.

         8.6     CONSTRUCTION; DEFINITIONS

         Unless the context requires otherwise, the general provisions, rules
of construction, and definitions in the General Corporation Law of Delaware
shall govern the construction of these by-laws.  Without limiting the

thereto, cancel the old certificate, and record the transaction in its books.

         8.11    STOCK TRANSFER AGREEMENTS

         The corporation shall have power to enter into and perform any

assessments the person registered on its books as the owner of shares, and
shall not be bound to recognize any equitable or other claim to or interest in
such share or shares on the part of another person, whether or not it shall

                      APPLIED ANALYTICAL INDUSTRIES, INC.
                           AND FREDERICK D. SANCILIO       



         THIS AGREEMENT made as of the 17th day of November, 1995, by and
between Applied Analytical Industries, Inc., a Delaware corporation
(hereinafter referred to as the "Company"), and Frederick D. Sancilio, Ph.D.
(hereinafter referred to as "Employee").

                                  WITNESSETH:

         WHEREAS:

         A.      Employee is currently employed by the Company as its Chairman
and President, is serving as its chief executive officer and is the founder and
controlling stockholder of the Company; and

         B.      The Company is raising capital through a private placement of
securities and, in connection with and to facilitate that transaction, wishes
to assure itself and the purchaser(s) of such securities that the Company will
continue to have the benefit of the Employee's extraordinary, unique and
special abilities, experience and services, and Employee is willing to enter
into an agreement to that end, upon the terms and conditions hereinafter set
forth; and

         C.      Employee acknowledges that but for his agreement to remain in
the Company's employ and to restrict his activities after termination of such
employment, as set forth herein, the purchasers of such securities would be
unwilling to purchase such securities on the present terms and conditions; and

         D.      Employee acknowledges that in connection with the private
placement of securities to the purchaser(s), Employee, as a shareholder of the
Company, is receiving a significant dividend from the Company's accumulated
adjustment account;

         NOW, THEREFORE, in consideration of good and valuable consideration
the receipt and sufficiency of which are hereby acknowledged, the parties
hereto hereby covenant and agree as follows:

         1.      Employment Agreement

<PAGE>   2

         (b)     On each anniversary of the Effective Date, the Term of
Employment then remaining shall be extended, automatically and without action
by the Company or Employee, for an additional period of one year, unless prior
to the anniversary in question either party gives the other party written
notice, in the manner set forth in section 15 below, that the party giving the
notice does not wish to extend the Term of Employment then remaining.  In the
event of any such extension, the  "Term of Employment" shall include the period
of such extension.  It is agreed and understood that Employee will not vote in
any vote of the Board of Directors of the Company concerning this Agreement.

         3.      Position, Duties and Responsibilities

         (a)     During the Term of Employment, Employee shall serve as, and
with the titles, offices and authority of, Chairman of the Board and President
of the Company, shall report only to the Board of Directors of the Company (the
"Board"), shall be the chief executive officer of the Company and, as such,
shall have effective supervision and control over, and responsibility for, the
strategic direction and general and active day-to-day leadership and management
of the business and affairs of the Company, subject to the authority of the
Board, and shall have all of the powers, authority, duties and responsibilities
usually incident to the positions and offices of Chairman of the Board and
President of the Company, and to the role of chief executive officer of the
Company, including but not limited to the authority to employ and discharge all
employees of the Company subject to approval of the Board with respect to
elected officers of the Company.

         (b)     During the Term of Employment, the Company shall use its best
efforts to cause Employee to be elected and re-elected (i) as a member of the
Board, (ii) as a member of the board of directors of any affiliate of the
Company on which board of directors Employee is serving on the date of this
Agreement, and (iii) as a member of the board of directors of any entity which
becomes a majority-owned subsidiary of the Company after the date of this
Agreement on which board of directors the Chairman of the Board, President and
chief executive officer of the Company would customarily serve.  Employee

Employment, without compensation in excess of that provided under this
Agreement.

         (c)     During the Term of Employment, Employee agrees to devote his

                                      -2-
<PAGE>   3

         (a)     Salary.  The Company shall pay Employee a salary at an annual
rate which shall be established from time to time by the Board, but which shall
not be less than $250,000.  Employee's salary shall be paid in substantially
equal installments at monthly or more frequent intervals, in accordance with
the normal payroll practices of the Company.  Employee's salary rate shall be
reviewed by the Board at least annually following the date of this Agreement to
ascertain whether, in the sole, good faith judgment of the Board, such rate
should be increased in light of Employee's performance, competitive pay levels
or such other factors (if any) as the Board may deem relevant.  Any increase in
salary shall not limit or reduce any other obligation of the Company under this
Agreement and, once established at an increased specified rate, Employee's
salary shall not thereafter be reduced.  Employee's annual salary under this
Agreement, at the rate specified above and including any increases, is
hereafter referred to as his "Salary".

         (b)     Bonus.  The Company shall provide Employee with the
opportunity to earn an annual bonus for each fiscal year, commencing with
fiscal year 1996, that commences within the Term of Employment, equal to at
least 50% of his Salary for such year if the Company attains the target bonus
performance objectives mutually agreed to by the Board and Employee for such
fiscal year; provided that the annual bonus for any fiscal year that does not
terminate within the Term of Employment shall be prorated.  It is agreed and
understood that Employee will not vote in any Board vote concerning his own
bonus.

         (c)     Other Incentive Plans.  During the Term of Employment,
Employee shall be eligible to participate in any other compensation or
incentive plans of a long or short term nature in which other senior executives
of the Company are then eligible to participate, subject to the terms and
conditions of such plans.  It is agreed and understood that eligibility to
participate is not synonymous with participation.  Employee shall participate
in any such plan only if the Board, in its sole discretion, selects Employee
for such participation.  It is agreed and understood that Employee will not
vote in any Board vote concerning his participation in any such plan.

         (d)     Perquisites.  During the Term of Employment, Employee shall be
entitled to perquisites of office, including without limitation air travel
privileges, office facilities and secretarial staff, and to fringe benefits,
including, without limitation, payment or reimbursement of membership dues in
one country club and one luncheon club, and of tax return preparation and
advisory fees, at least equal to and on the same terms and conditions as those
provided to Employee on the date of this Agreement (all such fringe benefits,
however, not in the aggregate to exceed $10,000 per year), as well as to
reimbursement, upon proper accounting, of all reasonable expenses and
disbursements incurred by him in the course of his duties, including, without
limitation, membership fees and dues in various professional, trade and civic
organizations, societies and associations which the Company has heretofore paid
or reimbursed.  Employee agrees to furnish an appropriate model automobile for
his use for business purposes, for which the Company shall pay Employee a
monthly automobile allowance of $750.   The Company shall also pay or reimburse
the airfare of Employee's spouse if she accompanies him on any business trip
that exceeds two weeks' duration, and shall indemnify and hold Employee
harmless against any income tax liability he incurs as a result of such payment
or reimbursement or this indemnity.

         (e)     Employee Benefits.  Employee, his dependents and
beneficiaries, including without limitation any beneficiary of a joint and
survivor or other optional method of payment applicable to the payment of
benefits under the Company's tax-qualified retirement plan(s), if any, shall be
entitled to all payments, benefits and age, pay and service credit for benefits
as a result of employment during the Term of Employment to which other senior
officers of the Company, their dependents and beneficiaries are then





                                      -3-
<PAGE>   4

entitled under the employee benefit plans and practices of the Company,
including without limitation any qualified or non-qualified pension, profit
sharing and savings plans, death benefit plans (including split dollar life
insurance plans and group life insurance plans providing group term life
insurance, accidental death and dismemberment insurance, and travel accident
insurance), sickness and disability benefit plans, vacation pay plans, and
medical, dental, health and welfare plans.  Nothing in this Agreement shall
preclude the Company from amending or terminating any employee benefit plan or
practice.  In any event, however, Employee shall be entitled to five weeks of
vacation with pay each year.  Any provision of this paragraph to the contrary
notwithstanding, Employee shall participate in any employee benefit plan that
is established after the date of this Agreement only if the Board of Directors,
in its sole discretion, permits him to participate.

         6.      Termination of Employment

         (a)     Death.  The Term of Employment shall terminate upon the death
of Employee.

         (b)     Disability.   The Term of Employment shall terminate in the
event of Disability of Employee.  As used in this Agreement, the term
"Disability" means an accident or physical or mental illness which prevents
Employee from substantially performing his duties and responsibilities
hereunder for six months (consecutive or otherwise) within any twelve
consecutive month period.  The Term of Employment shall terminate at the close
of business on the last day of such six month period, but without prejudice to
any payments due Employee in respect of disability under any pension or welfare
plan.  The amount of any Salary or other compensation payable to Employee
during such six month period as a result of this paragraph may be reduced by
any payments which Employee receives for the same period because of disability
under any disability or pension plan of the Company or any affiliate of the
Company.

         (c)     Cause.  The Company may terminate the Term of Employment for
Cause.  For purposes of this Agreement, Employee shall be considered to be
terminated for "Cause" only if (i) Employee has --

                 (A)      willfully failed to comply with any of the material
terms of this Agreement;

                 (B)      willfully and continually failed to perform his
duties hereunder;

                 (C)      willfully engaged in misconduct materially injurious
to the Company; or

                 (D)      been convicted of a felony or a crime of moral
turpitude;

and (ii) a resolution is adopted by a vote of the majority of the members of
the Board (excluding Employee) finding that Employee has engaged in conduct
referred to in (A), (B), (C) or (D) above, specifying the particulars in
reasonable detail, and (iii) Employee received thirty (30) days' advance
written notice that the Board intended to meet to consider Employee's
termination for Cause and Employee was given a reasonable opportunity to be
heard by the Board on the issue prior to the Board's vote on the matter.

         (d)     Constructive Discharge.  Employee may terminate his employment
under this Agreement on 10 days' advance written notice to the Company given
within 90 days after the occurrence of a Constructive Discharge Event.  For
purposes of this Agreement, "Constructive Discharge Event" means





                                      -4-
<PAGE>   5

any act or omission identified below in this paragraph 6(d) to which Employee
does not consent in writing and which does not occur in connection with
termination of Employee's employment for Cause or Disability as defined in this
Agreement; provided that no such act or omission shall constitute a
Constructive Discharge Event unless and until Employee gives the Board written
notice describing the act or omission in reasonable detail within 60 days after
the Employee first knows (or should have known) of the act or omission and the
act or omission is not cured within 30 days after the Board receives such
written notice:

         (i)     Any (A) failure to re-designate Employee as, or (B) removal of
Employee from, or failure to re-elect Employee to, any of the following
positions:

                 (I)      Chairman of the Board, President and chief executive
officer of the Company, or

                 (II)     a member of the Board of Directors of (aa) the
Company, (bb) any affiliate of the Company on whose Board of Directors Employee
now serves, and (cc) any future majority-owned subsidiary of the Company on
whose Board of Directors the Chairman of the Board, President and chief
executive officer of the Company would customarily serve;

         (ii)    (A)      Any conduct by the Board, or

                 (B)      any assignment to Employee of any duties, functions,
authority or responsibilities by the Board,

that in either case (A) or (B) --

                          (I)     calls for Employee to report to anyone other
than the Board, or

                          (II)    deprives Employee of effective supervision
and control over, and responsibility for, the strategic direction and general
and active day-to-day leadership and management of the business and affairs of
the Company, subject to the authority of the Board, or

                          (III)   is substantially inconsistent with or
deprives Employee of any of the material duties, functions, authority or
responsibilities incident to his positions described above, including the
authority to hire and discharge all employees of the Company subject to
approval of the Board in the case of elected officers, or

                          (IV)    substantially interferes with Employee's
ability to substantially perform the duties, functions or responsibilities, or
exercise the authority, of his positions described in section 3 above;

         (iii)   any material failure by the Company to comply with the
provisions of section 4 above (relating to office location) or section 5 above
(relating to compensation and related matters).

A termination by Employee in accordance with the provisions of this paragraph
6(d) shall not be deemed a voluntary termination of employment by Employee for
the purpose of this Agreement or any plan or practice of the Company or its
affiliates.





                                      -5-
<PAGE>   6

         (e)     Termination by Company Not for Cause.  Notwithstanding any
provision of this Agreement to the contrary, the Board shall have the right to
terminate Employee's employment for any reason other than Cause at any time,
subject to the consequences of such termination as set forth in this Agreement.

         (f)     Notice of Termination.  Any termination by the Company for
Disability or Cause as defined in paragraph 6(b) and (c) or by Employee
pursuant to paragraph 6(d) hereof (relating to Constructive Discharge Events)
shall be communicated by written Notice of Termination to the other party
hereto.  For purposes of this Agreement, a "Notice of Termination" shall mean a
notice which shall indicate the specific termination provision in this
Agreement relied upon and shall set forth in reasonable detail the facts and
circumstances claimed to provide a basis for termination of Employee's
employment under the provision so indicated.  If any dispute concerning
termination of Employee's employment under paragraphs 6(b), (c) or (d) above
results in a final determination that a proper basis for such termination did
not exist, Employee's employment hereunder shall be treated as having been
terminated other than pursuant to paragraph 6(b), (c) or (d), as the case may
be, by the party who gave Notice of Termination.

         7.      Compensation for Termination and Related Matters

         The parties recognize and agree that, if the Company terminates
Employee's employment under this Agreement other than for Disability pursuant
to paragraph 6(b) above or Cause pursuant to paragraph 6(c), or if Employee
terminates his employment in accordance with paragraph 6(d) above following a
Constructive Discharge Event, the actual damages to Employee would be difficult
if not impossible to ascertain.  Accordingly, the parties agree that, if the
Company terminates Employee's employment under this Agreement other than for
Disability pursuant to paragraph 6(b) above or Cause pursuant to paragraph
6(c), or if Employee terminates his employment in accordance with paragraph
6(d) above following a Constructive Discharge Event, (any such termination by
the Company or Employee being hereafter referred to as a "Compensable
Termination"), then Employee shall thereupon be relieved of any further
obligation under this Agreement other than sections 9 and 10 hereof (relating
to restrictive covenants and intellectual property) and his sole remedy shall
be a right to receive from the Company, as liquidated damages, severance pay or
both, the payments and benefits provided in paragraphs 7(a) through (and
including) 7(e) below; provided that no provision of this section 7 is intended
to curtail, reduce or otherwise affect adversely any rights Employee may have
in respect of termination of employment under any compensation, incentive or
employee benefit plan or any rights Employee may have under section 8 hereof to
put shares to the Company.  Employee shall not be required to mitigate the
amount of any payment or benefit provided for in this section 7 by seeking
other employment or otherwise, nor shall any compensation earned by Employee in
other employment or otherwise reduce the amount of any payment or benefit
provided for in this section.

         (a)     The Company shall pay Employee his Salary (as defined in
paragraph 5(a) above) prorated through the date of termination;

         (b)     The Company shall pay Employee any accrued but unpaid bonus
award for Employee's services in the fiscal year preceding the date of
termination, and a prorated bonus award for the fiscal year in which the date
of termination occurs, such prorated bonus award to be determined by
multiplying the "Target Bonus" as defined in paragraph 7(d) below by a fraction
the numerator of which is the number of days in the calendar year of
termination that precede the date of termination and the denominator of which
is the number 365;





                                      -6-
<PAGE>   7

         (c)     The Company shall pay Employee an amount equal to two times
his Salary (as defined in paragraph 5(a) above), in 24 substantially equal
monthly installments commencing on or before the tenth day after the date of
termination and continuing at monthly intervals thereafter;

         (d)     The Company shall pay Employee an amount equal to two times
the "Target Bonus" as hereafter defined, in 24 substantially equal monthly
installments commencing on or before the tenth day after the date of
termination and continuing at monthly intervals thereafter.  For purposes of
this section 7, the  "Target Bonus" shall mean fifty percent (50%) of
Employee's Salary (as defined in paragraph 5(a) above);

         (e)     The Company shall provide Employee, his dependents and
beneficiaries with the medical insurance benefits and life insurance benefits
which they would receive under paragraph 5(e) of this Agreement if the Term of
Employment were to continue for two years after the date of termination and the
compensation described in paragraphs 7(c) and (d) above were paid to him in the
capacity of an employee (rather than a former employee); provided, however,
that if and to the extent the Company determines that such benefits cannot be
provided under the plans in question due to Internal Revenue Code or other
restrictions, the Company shall provide tax-equivalent benefits through other
means reasonably satisfactory to Employee, and, provided further, that if
Employee obtains full time employment within two years after his date of
termination, any benefits to be provided under this paragraph shall be reduced
to the extent Employee receives benefits under comparable plans of the
successor employer.

         8.      Employee's Put

         If a Compensable Termination (as defined in section 7 above) occurs
before equity securities of the Company or a successor to the Company, or
securities convertible into or exchangeable for such equity securities, are
first sold to the public pursuant to a registration statement complying with
section 5 of the Securities Act of 1933 as amended (an "Initial Public
Offering"), or if the Term of Employment terminates before an Initial Public
Offering by reason of Disability as provided in paragraph 6(b) above, then at
any time within three months after the date on which such Compensable
Termination (or termination by reason of Disability) occurs and before such an
Initial Public Offering occurs Employee may elect to sell to the Company, and
cause the Company to purchase from Employee, any or all shares of Company
common stock (or successor securities) then beneficially owned by Employee, but
in no event more than ten percent of the shares of Company common stock (or
successor securities) then issued and outstanding.  In the event such an
election is timely made, the Company shall purchase from Employee the shares to
which the election relates (but in no event more than ten percent of the shares
of Company common stock (or successor securities) then issued and outstanding).
It shall be a condition to the Company's obligation to purchase such shares
that Employee give prior written notice (which shall be irrevocable) to the
Company which shall set forth the number of shares to which the election
relates and the date of such sale, which shall be not less than 90 nor more
than 120 days after the date of the giving of the notice.  In the event of any
such sale, the amount which the Company shall pay Employee for the shares being
sold shall be equal to the Fair Market Value of such shares on the date on
which the Compensable Termination or termination for Disability occurred.   The
Company shall pay Employee twenty-five percent (25%) of the purchase price (or
such higher percentage thereof as the Company may in its sole discretion
direct) on the sale date.  Any balance of the purchase price shall be paid in
three equal annual installments of principal, one of which shall be payable on
each anniversary of the sale date through and including the third anniversary
thereof; provided that the Company may elect to pre-pay any or all such
installments (or any portion of any installment) at any time and without
penalty.  Any portion





                                      -7-
<PAGE>   8

of the purchase price which is payable after the sale date pursuant to this
section shall accrue interest at the lowest rate that will avoid imputation of
interest under Federal income tax rules applicable to the sale.  Any such
accrued interest shall be paid with each installment of principal.  Each
payment to be made to Employee pursuant to this section shall be made by
certified check or bank check drawn on a U.S. bank, payable to the order of
Employee or his designee.  For purposes of this section 8, Fair Market Value
shall be determined by averaging the fair market value of a share of common
stock without regard to any control premium, as determined by two independent
appraisers, whose fees and expenses shall be paid by the Company and who shall
be mutually selected by Employee and the Company.  If Employee and the Company
are able to mutually agree on only one appraiser, then the second appraiser
shall be selected by the first.  If Employee and the Company are unable to
mutually agree on any appraiser within 20 days after Employee gives such
notice, then the two appraisers shall be selected within 10 days thereafter by
an arbitrator designated by the American Arbitration Association, whose fees
and expenses shall be paid by the Company.

         9.      Restrictive Covenants

         (a)     Employee covenants and agrees that during the 24 months
following the termination of his employment with the Company for any reason
(including, without limitation, a Compensable Termination, a termination that
is not a Compensable Termination and a termination of employment following the
expiration of the Term of this Agreement), he will not engage in "Competition"
with the Company.  For this purpose, "Competition" means --

                 (i)      directly or indirectly, taking or contracting to take
a management, advisory, operational, sales, employment or ownership position
with, or control of, a business engaged in the development, formulation,
testing, manufacturing, marketing, distribution or sale of pharmaceutical
products (including, without limitation, generic drug products, whether
prescription or otherwise) or services to the pharmaceutical industry; provided
that in no event shall ownership of less than 1% of the outstanding equity
securities of any issuer whose securities are registered under the Securities
Exchange Act of 1934, standing alone, be deemed Competition for this purpose
and, provided further, that this provision shall not restrict Employee from
employment or other association with the ethical portion of a pharmaceutical
company or a not-for-profit institution that is not developing generic
pharmaceutical products;

                 (ii)     soliciting any person or business who or which is a
supplier, customer or client of the Company or any of its subsidiaries or
affiliates, on behalf of a competitive business described in clause (i) above
of this subparagraph 9(a), or inducing any such person or business to
terminate, reduce or otherwise alter to the detriment of the Company, its
subsidiaries or affiliates their business with the Company, its subsidiaries or
affiliates; or

                 (iii)    inducing or attempting to persuade any employee of
the Company, its subsidiaries or affiliates to terminate his or her employment
relationship, or offering employment to any employee of the Company, its
subsidiaries or affiliates on behalf of any person or entity other than the
Company, its subsidiaries or affiliates.

Employee further covenants and agrees that during such 24 months' period he
will not otherwise act or conduct himself to the detriment of the Company, its
subsidiaries or affiliates.





                                      -8-
<PAGE>   9

         (b)     Employee agrees not to disclose, either while in the Company's
employ or at any time thereafter, to any person not employed by the Company, or
not engaged to render services to the Company, except with the prior written
consent of an authorized officer of the Company or as necessary or appropriate
for the performance of his duties hereunder, any confidential information
obtained by him while in the employ of the Company, including, without
limitation, information relating to any of the inventions, processes, formulae,
plans, devices, compilations of information, research, methods of distribution,
suppliers, customers, client relationships, marketing strategies, trade secrets
or other proprietary information of the Company, its subsidiaries or
affiliates; provided, however, that this provision shall not preclude Employee
from use or disclosure of information known generally to the public or from
disclosure required by law or court order.  Employee agrees that, in the event
his employment with the Company terminates for any reason, he shall promptly
return to the Company all property of the Company, its subsidiaries and
affiliates in his possession or under his direct or indirect control, including
without limitation any record, list, drawing, blueprint, specification,
material, document, diary or compilation of data, whether printed, typed,
handwritten, on diskette or on any other computer media, relating to its or
their methods of distribution, testing, suppliers, customers, client
relationships, marketing strategies, business plans or any description of any
formulae or secret processes, or which was obtained by him or entrusted to him
during the course of his employment with the Company.

         (c)     Employee recognizes and agrees that, by reason of his
knowledge, experience, skill and abilities, his services are extraordinary and
unique, that the breach or attempted breach of the restrictions set forth above
in this section will result in immediate and irreparable injury for which the
Company will not have an adequate remedy at law, and that the Company shall be
entitled to a decree of specific performance of those restrictions and to a
temporary and permanent injunction enjoining the breach thereof, and to seek
any and all other remedies to which the Company may be entitled, including,
without limitation, monetary damages, without posting bond or furnishing
security of any kind.

         (d)     Employee agrees that the Company shall not be obligated to
make any payments or provide any benefits pursuant to this Agreement if
Employee shall, during the period in which such payments are being made or
benefits provided, engage in Competition as defined above or otherwise act or
conduct himself to the detriment of the Company, its subsidiaries or
affiliates.  The foregoing provisions of this subparagraph are in addition to
and not by way of limitation of any other rights and remedies available to the
Company.

         (e)     Employee specifically and expressly represents and warrants
that (i) he has reviewed and agreed to the restrictive covenants contained in
this Agreement and their contemplated operation after receiving the advice of
counsel of his choosing; (ii) he believes, after receiving such advice, that
the restrictive covenants and their contemplated operation are fair and
reasonable; (iii) he will not seek or attempt to seek to have the restrictive
covenants declared invalid, and, after receiving the advice of counsel,
expressly waives any right to do so; and (iv) if the full breadth of any
restrictive covenant and/or its contemplated operation shall be held in any
fashion to be too broad, such covenant or its contemplated operation, as the
case may be, shall be interpreted in a manner as broadly in favor of the
beneficiary of such covenant as is legally permissible.  Employee recognizes
and agrees that the restrictions on his activities contained in this section
are required for the reasonable protection of the Company and its investments.





                                      -9-
<PAGE>   10

         10.     Intellectual Property

         Employee agrees that all "Intellectual Property" which is or was at
any time made or conceived by Employee, acting alone or in conjunction with
others, during Employee's employment with the Company, is or shall be the
property of the Company, free of any reserved or other rights of any kind on
Employee's part.  During the Term of Employment and thereafter Employee shall
promptly make full disclosure of any such Intellectual Property to the Company
and, at its cost and expense, do all acts and things (including, among others,
the execution and delivery under oath of patent and copyright applications and
instruments of assignment) deemed by the Company to be necessary or desirable
at any time in order to effect the full assignment to the Company of Employee's
right and title, if any, to such Intellectual Property.  For purposes of this
Agreement, "Intellectual Property" means any discovery, development, program,
concept, idea, process or improvement, whether or not patentable, relating to
the present or planned future activities, business, products or services of the
Company, its subsidiaries or affiliates.

         11.     Successors; Binding Agreement

         (a)     The Company will require any successor (whether direct or
indirect, by purchase, merger, consolidation or otherwise) to all or
substantially all of the business and/or assets of the Company to expressly
assume and agree to perform this Agreement in the same manner and to the same
extent that the Company would be required to perform it if no such succession
had taken place.  Failure of the Company to obtain such agreement prior to the
effectiveness of any such succession shall entitle Employee to compensation
under section 7 above and to put shares to the Company pursuant to section 8
above, in the same amount and on the same terms as he would be entitled to
hereunder if his employment were terminated by the Company other than for
Disability or Cause, except that for purposes of implementing the foregoing,
the date on which any such succession becomes effective shall be deemed the
date of termination.

         (b)     As used in this Agreement, the "Company" shall mean the
Company as hereinbefore defined and any successor to its business and/or assets
as aforesaid which executes and delivers an agreement provided for in this
section 11 or which otherwise becomes bound by all the terms and provisions of
this Agreement by operation of law.

         (c)     This Agreement and all rights of Employee hereunder shall
inure to the benefit of and be enforceable by Employee's personal or legal
representatives, executors, administrators, successors, heirs, distributees,
devisees and legatees.  If Employee should die while any amounts are due and
payable to him hereunder, all such amounts, unless otherwise provided herein,
shall be paid to Employee's designated beneficiary or, if there be no such
designated beneficiary, whether because none was designated or because none is
alive or in existence at the time any amount becomes payable hereunder, to the
legal representatives of Employee's estate.

         (d)     Except as to withholding of any tax under the laws of the
United States or any other country, state or locality, neither this Agreement
nor any right or interest hereunder nor any amount payable at any time
hereunder shall be subject in any manner to alienation, sale, transfer,
assignment, pledge, attachment, or other legal process, or encumbrance of any
kind by Employee or the beneficiaries of Employee or by his legal
representatives without the Company's prior written consent, nor shall there be
any right of set-off or counterclaim in respect of any debts or liabilities of
Employee, his beneficiaries or legal representatives; provided, however, that
nothing in this paragraph shall preclude Employee from





                                      -10-
<PAGE>   11

designating a beneficiary to receive any benefit payable on his death, or the
legal representatives of Employee from assigning any rights hereunder to the
person or persons entitled thereto under his will or, in case of intestacy, to
the person or persons entitled thereto under the laws of intestacy applicable
to his estate.

         12.     Agreement Binding

         This Agreement shall be binding upon and shall inure to the benefit of
Employee, his heirs and legal representative(s), and the Company, its
successors and assigns and any person, firm, corporation or other entity which
succeeds to all or substantially all of the business, assets or property of the
Company, as provided in section 11 hereof.

         13.     General

         (a)     This Agreement contains the entire understanding of the
parties with respect to the subject matter hereof and cancels and supersedes
any and all other agreements between the parties with respect to the subject
matter hereof, including the employment agreement and the memorandum of
understanding among the parties and James L. Waters dated October 27, 1992.

         (b)     The Company recognizes that, within 90 days after the
execution of this Agreement, Employee and GenerEst, Inc. ("GenerEst") intend to
amend the Noncompetition Agreement dated November 25, 1994 between Employee and
GenerEst to provide for the employment of Employee by GenerEst in a senior
officer position at an annual salary of $100,000, with the opportunity to earn
an annual bonus amounting to 50% of such salary if target bonus performance
goals mutually agreed to by GenerEst and Employee are attained, or a higher
amount (to be determined by the board of directors of GenerEst, excluding
Employee) if such goals are exceeded, and with other terms and conditions to be
determined by mutual agreement of GenerEst and Employee on a reasonable basis.
The Company agrees that, if such Noncompetition Agreement is not so amended
within 90 days after the execution of this Agreement (for any reason other than
Employee's failure to use his reasonable best efforts to so amend such
Noncompetition Agreement), Employee's annual Salary as defined above in
paragraph 5(a) shall automatically and without further action by the parties
hereto be increased, effective as of the date of this Agreement, by $100,000
for all purposes of this Agreement.  The Company agrees to use its reasonable
best efforts to cause GenerEst to so amend such Noncompetition Agreement and to
cause Employee to be elected a senior officer of GenerEst, and agrees that, any
provision of this Agreement to the contrary notwithstanding, neither the
execution by Employee of such amended Noncompetition Agreement as aforesaid nor
the performance by Employee of his obligations thereunder shall be deemed to
constitute a breach of this Agreement in any way.

         (c)     Any modification of this Agreement shall not be binding unless
in writing and signed by the Company and Employee.

         (d)     Notwithstanding anything contained in this Agreement to the
contrary, to the extent that the payments and benefits provided under this
Agreement (such payments and benefits are collectively referred to as the
"Payments"), when added to the benefits provided to, or for the benefit of,
Employee under any other Company plan or agreement, would be subject to the
excise tax (the "Excise Tax") imposed under Section 4999 of the Internal
Revenue Code of 1986, as amended (the "Code"), the Payments shall be reduced
(but not below zero) if and to the extent necessary so that no Payment to be
made or provided to Employee shall be subject to the Excise Tax (such reduced
amount is hereinafter





                                      -11-
<PAGE>   12

referred to as the "Limited Payment Amount").  Unless Employee shall have given
prior written notice specifying a different order to the Company to effectuate
the Limited Payment Amount, the Company shall reduce or eliminate the Payments,
by first reducing or eliminating those payments or benefits which are not
payable in cash and then by reducing or eliminating cash payments, in each case
in reverse order beginning with payments or benefits which are to be paid the
farthest in time from the determination (as hereinafter defined).  Any notice
given by Employee pursuant to the preceding sentence shall take precedence over
the provisions of any other plan, arrangement or agreement governing Employee's
rights and entitlements to any benefits or compensation.

         (e)     Enforceability

         In the event that any provision of this Agreement is determined to be
invalid or unenforceable, the remaining terms and conditions of this Agreement
shall be unaffected and shall remain in full force and effect, and any such
determination of invalidity or unenforceability shall not affect the validity
or enforceability of any other provision of this Agreement.

         (f)     Notices

         All notices which may be necessary or proper for either the Company or
Employee to give to the other shall be in writing and shall be delivered by
hand or sent by registered or certified mail, return receipt requested, or by
air courier, to Employee at:

party may by like notice to the other party change the address at which he or
it is to receive notices hereunder.

         E.      Arbitration

Agreement, or the breach thereof, shall be settled by binding arbitration in
the County of New Hanover, State of North Carolina, in accordance with the

arbitrator's decision shall be binding and final, and judgment upon the award
rendered may be entered in any court having jurisdiction thereof.

                      APPLIED ANALYTICAL INDUSTRIES. INC.

                        1995 RESTRICTED STOCK AWARD PLAN

                            AMENDED AND RESTATED


1.   PURPOSE

     The purpose of the Applied Analytical Industries, Inc. 1995 Restricted
Stock Award Plan (the "Plan") is to promote the growth and profitability of
Applied Analytical Industries, Inc. (the "Company") by increasing the personal
participation of certain employees in the financial performance of the Company,
to compensate such employees for their contributions to the success of the
Company and to assure the continued participation of such employees in growth
of the Company.  This purpose will be achieved through the grant of restricted
stock awards ("Restricted Stock Awards") consisting of shares of the Company's
Class B Non-Voting Common Stock ("Class B Stock") to participants in the Plan
subject to vesting requirements, restrictions on transfer and risk of
forfeiture upon termination of employment as set forth herein.

     2.  ADMINISTRATION

                      APPLIED ANALYTICAL INDUSTRIES, INC.
                             1995 STOCK OPTION PLAN
                              AMENDED AND RESTATED

1.       PURPOSE

         The purpose of the Applied Analytical Industries, Inc. 1995 Stock
Option Plan (the "Plan") is to promote the growth and profitability of Applied
Analytical Industries, Inc. (the "Company") and its subsidiaries
("Subsidiaries") from time to time by increasing the personal participation of
officers and key employees in the financial performance of the Company and by
providing such officers and key employees with an equity opportunity in the
Company.  This purpose will be achieved through the grant of stock options
("Options") to purchase shares of Class B Non-Voting Common Stock of the
Company (the "Class B Stock") subject to restrictions on transfer or such other
restrictions as the administrators of the Plan may determine.

2.       ADMINISTRATION

         The Plan will be administered by the Company's Board of Directors (the
"Board"); provided, however, that from and after the registration of any class
of equity securities of the Company pursuant to Section 12 of the Securities
Exchange Act of 1934, as amended, if the Board includes members who are not
"disinterested persons" (as defined in Rule 16b-3 promulgated under the
Securities Exchange Act of 1934, as amended, or any applicable successor rule
or regulation ) or "outside directors" (as defined in Section 162(m) of the
Internal Revenue Code of 1986, as amended, and the regulations thereunder),
then all authority of the Board under the Plan shall be exercised by a
committee of the Board (the "Committee") composed solely of members thereof who
are both "disinterested persons" and "outside directors" (as so defined).

         The Board or the Committee shall have complete authority to: (i)
interpret all terms and provisions of the Plan consistent with law; (ii) select
from the group of officers and key employees eligible to participate in the
Plan the officers and key employees to whom Options shall be granted; (iii)
within the limits established herein, determine the number of shares to be
subject to and the exercise price of, each Option; (iv) prescribe the form of
instruments) evidencing Options granted under the Plan; (v) determine the time
or times at which Options shall be granted to officers or key employees; (vi)
provide, if appropriate, for the exercisability of Options in installments or
subject to specified conditions; (vii) determine the method of exercise of
Options; (viii) adopt, amend and rescind general and special rules and
regulations for the Plan's administration; and (ix) make all other
determinations necessary or advisable for the administration of the Plan.



<PAGE>   2


         Any action which the Board or the Committee is authorized to take may
be taken without a meeting if all the members of the Board or the Committee
sign a written document authorizing such action to be taken, unless different
provision is made by the By-Laws of the Company or by resolution of the Board
or the Committee.

         The Board or the Committee may designate selected Board or Committee
members or certain employees of the Company to assist the Board or the
Committee in the administration of the Plan and may grant authority to such
persons to execute documents, including Options, on behalf of the Board or the
Committee.

         No member of the Board or the Committee or employee of the Company
assisting the Board or the Committee pursuant to the preceding paragraph shall
be liable for any action taken or determination made in good faith.


3.       STOCK SUBJECT TO PLAN

         The stock to be offered under the Plan shall be shares of Class B
Stock previously issued and thereafter acquired by the Company pursuant to an
agreement entered into by the Company and Frederick D. Sancilio and James L.
Waters in connection with the adoption of the Plan.  An aggregate of 1,917.3
shares of Class B Stock may be issued upon exercise of Options granted under
the Plan; provided, however, notwithstanding any other provision of this Plan,
the Corporation shall have no obligation or liability to deliver or issue any
shares of Class B Stock or other capital stock upon the exercise of any Option
to the extent it has not purchased such shares from Frederick D. Sancilio or
James L.  Waters for issuance to the Option holder.  Any or all of the Options
granted under Section 4 hereof may, at the Board or the Committee's discretion,
be intended to qualify as incentive stock options ("Incentive Stock Options")
under Section 422 of the Internal Revenue Code of 1986, as amended (the
"Code").  The number of shares to be issued under the Plan may be adjusted to
reflect any change in the capitalization of the Company as contemplated by
Section 9 hereof and occurring after the adoption of the Plan.  The Board or
the Committee will maintain records showing the cumulative total of all shares
subject to Options outstanding under the Plan.

4.       OPTION AWARDS

         (a)     Eligibility and Factors Considered in Granting Options

         The grant of Options under this Section 4 shall be limited to those
officers and key employees of the Company or any of its Subsidiaries who have
made the greatest contribution to the Company's long-term performance and are
selected by the Board or the Committee.  In making any determination as to the
officer(s) and key employees) to whom Options shall be granted under this
Section 4 and as to the number of shares to be subject thereto, the Board or
the Committee shall take into account, in each case, the level and





                                     -2-
<PAGE>   3



responsibility of the person's position, the level of the person's performance,
the person's level of compensation, the assessed potential of the person and
such additional factors as the Board or the Committee shall deem relevant to
the accomplishment of the purposes of the Plan.

         (b)     Allotment of Shares

         The Board or the Committee, in its sole discretion and subject to the
provisions of the Plan, may grant to participants eligible under this Section
4, on or after the date hereof, Options.  Options may be, at the discretion of
the Board or the Committee: (i) Options that are intended to qualify as
Incentive Stock Options; or (ii) Options that are not intended to be Incentive
Stock Options; or (iii) both of the foregoing, if granted separately, and not
in tandem.  Each Option granted under the Plan must be clearly identified as to
its status as an Incentive Stock Option or not.

         Options granted under this Section 4 may be allotted to participants
in such amounts, subject to the limitations specified in the Plan, as the Board
or the Committee, in its sole discretion, may from time to time determine,
provided that no participant may be granted Options with respect to more than
1,500 shares of Class B Stock.

         In the case of Options intended to be Incentive Stock Options, the
aggregate fair market value (determined at the time of such Incentive Stock
Options' respective grants) of the shares with respect to which Incentive Stock
Options are exercisable for the first time by a participant hereunder during
any calendar year (under all plans taken into account pursuant to Section
422(d) of the Code) shall not exceed $100,000.  Options under this Section 4
not intended to qualify as Incentive Stock Options may be granted to any Plan
participant without regard to the Section 422(d) limitations.

         (c)     Time of Granting Options

         The date of grant of an Option under this Section 4 shall be, for all
purposes, the date on which the Board or the Committee makes the determination
of granting such Option (each such date, a "Grant Date").  Notice of the
determination shall be given to each officer or key employee to whom an Option
is so granted under this Section 4 within a reasonable time after the Grant
Date.

         (d)     Exercise Price for Options

         The price per share at which each Option granted under this Section 4
may be exercised shall be such price as shall be determined by the Board or the
Committee at the time of grant based on such criteria as may be adopted by the
Board or the Committee at the time of grant in good faith, taking into account,
in each case, the market price of the common stock, the level and
responsibility of the person's position, the level of the person's performance,
the person's level of compensation, the assessed potential of the person, and





                                     -3-
<PAGE>   4


such additional factors as the Board or the Committee shall deem relevant to
the accomplishment of the purposes of the Plan; provided, however, that in no
event shall the exercise price per share of an Option be less than 100% of the
fair market value of the Company's shares of common stock on the Grant Date for
such Option unless such grant is approved by all directors and in no event
shall be less than 75% of the fair market value of the Company's shares of
common stock on the Grant Date for such Option.  In the case of an Option
intended to qualify as an Incentive Stock Option, the price per share shall not
be less than 100% (or 110% for owners of more than 10% of the total combined
voting power of all classes of stock of the Company or any Subsidiary) of the
fair market value of the Class B Stock on the Grant Date for such Option.

         If the Company's shares of common stock are:

         (1)     actively traded on any national securities exchange or NASDAQ
system that reports their sales prices, fair market value shall be the average
of the high and low sales prices per share on any Grant Date;

         (2)     otherwise traded over the counter, fair market value shall be
the average of the final bid and asked prices for the shares of common stock as
reported for any Grant Date; or

         (3)     not traded, the Board or the Committee shall consider any
factor or factors that it believes affects fair market value, and shall
determine fair market value without regard to any restriction other than a
restriction that by its terms will never lapse.

         (e)     Term of Options

         The term of each Option granted under this Section 4 shall be
established by the Board or the Committee, but shall not exceed 1 0 years (or 5
years for owners of more than 1 0 % of the total combined voting power of all
classes of stock of the Company or of a Subsidiary) from the Grant Date for
such Option.

         (f)     Cancellation and Replacement of Options

         The Board or the Committee may at any time or from time to time permit
the voluntary surrender by the holder of any outstanding Option granted under
this Section 4 where such surrender is conditioned upon the granting under this
Section 4 to such holder of new Option(s) for such number of shares as the
Board or the Committee shall determine, or may require such a voluntary
surrender as a condition precedent to the grant under this Section 4 of new
Option(s) to such holder.

         The Board or the Committee shall determine the terms and conditions of
any such new Option(s), including their exercise price and the periods during
which they may be exercised, subject to and in accordance with the provisions
of the Plan, all or any of which





                                     -4-
<PAGE>   5


may differ from the terms and conditions of the Option(s) surrendered.  Any
such new Option(s) shall be subject to all the relevant provisions of the Plan.

         The shares subject to any Option so surrendered or otherwise
terminated shall no longer be charged against the limitation or limitations
provided in Section 3 of the Plan and may thereafter become the subject of new
Option grants under the Plan.

         The granting of new Option(s) in connection with the surrender of
outstanding Option(s) under the Plan shall be considered for the purposes of
the Plan as the grant of new Option(s) and not an alteration, amendment or
modification of the Plan or of the Option(s) being surrendered.

                             voting powers of the Company's then outstanding

                             plan of merger or consolidation providing for the
                             merger or consolidation of the Company with
                             another corporation (other than an affiliate of
                             the Company within the meaning of the Securities
                             Exchange Act of 1934, as amended) and as a result
                             of such merger or consolidation less than 75% of
                             the outstanding voting securities of the surviving

                             of its assets to another corporation or entity
                             which is not a wholly owned subsidiary of the
                             Company.

Notwithstanding any other provision of the Plan, any Option granted to Dr.
James Swarbrick shall become fully vested and exercisable at age 65 (and the
term of such Option shall expire on the earlier of ten years after the Grant
Date and five years after the date Dr. Swarbrick becomes age 65) and upon any
grant of an Option to Dr. James Swarbrick the Company shall enter into an
agreement with Dr. Swarbrick granting Dr. Swarbrick the right to require the
Company to purchase on the date Dr. Swarbrick becomes age 65 and on the

next four anniversaries of such date an amount of shares of common stock equal
to 10% of the shares initially purchasable under such Option at the fair market
value of such shares (as determined pursuant to Section 4(d)) on the date of
purchase by the Company.

5.      NON-TRANSFERABILITY

        An Option granted to a participant under the Plan shall not be
transferable by him or her except: (i) by will; (ii) by the laws of descent
and distribution; or (iii) pursuant to a qualified domestic relations order as
defined by the Code or in Title I of the Employee Retirement Income Security
Act, or the rules thereunder.  In the case of an Option intended to be an
Incentive Stock Option, such Option shall not be transferable by a participant
other than by will or the laws of descent and distribution and during the
optionee's lifetime shall be exercisable only by him or her.

6.      EXERCISABILITY OF OPTIONS

        Subject to the provisions of the Plan, Options granted under Section 4
hereof shall be exercisable at such time or times after the Grant Date to the
extent such Options are vested.

        Any Option shall terminate in full (whether or not previously
exercisable) prior to the expiration of its term on the date the optionee
ceases to be an employee of the Company or any Subsidiary of the Company,
unless (i) the optionee shall (a) die while an employee of the Company or such
Subsidiary, in which case the participant's legatee(s) under his or her last
will -or the participant's personal representative or representatives may
exercise all or part of the previously unexercised portion of such Option at
any time within one year, but not beyond the expiration of its term, after the
participant's death to the extent the optionee could have exercised the Option
immediately prior to his or her death, lb) become permanently or totally
disabled within the meaning of section 22(e)(3) of the Code (or any successor
provision) while an employee of the Company or such Subsidiary, in which case
the participant or his or her personal representative may exercise the
previously unexercised portion of such Option at any time within one year, but
not beyond the expiration of its term, after termination of his or her
employment or directorship to the extent the optionee could have exercised the
Option immediately prior to such termination, or (c) resign or retire after age
62 with the consent of the Company, in which case the participant may exercise
the previously unexercised portion of such Option at any time within six
months, but not beyond the expiration of its term, after the participant's
resignation or retirement to the extent the optionee could have exercised the
Option immediately prior to such resignation or retirement, or (ii) the Board
or the Committee shall determine otherwise.

 In no event may an Option be exercised after the expiration of its fixed term.

7.      METHOD OF EXERCISE

        Each Option granted under the Plan shall be deemed exercised when the
holder (a) shall indicate the decision to do so in writing delivered to the
Company, and (b) shall at the same time tender to the Company payment in full
of the exercise price for the shares for which the Option is exercised, which
payment may be made in cash.  The exercise of any option granted under the Plan
may be made subject to the condition that, if at any time the Board or the
Committee shall determine, in its discretion, that the satisfaction of
withholding tax or other withholding liabilities under any state or federal law
is necessary or desirable as a condition of, or in connection with, such
exercise or the delivery or purchase of shares pursuant thereto, then in such
event, the exercise of the option shall not be effective unless such
withholding tax or other withholding liabilities shall have been satisfied in a
manner acceptable to the Company, which may include the withholding by the
Company of shares of Class B Stock to be issued upon exercise of an Option
having a fair market value equal to the required withholding amount.  With
respect to the foregoing sentences, the value of the shares of Class B Stock
shall be the fair market value determined in accordance with Section 4(d) of
the Plan as of the day of such payment or withholding.

        No person, estate or other entity shall have any of the rights of a
shareholder with reference to shares subject to an Option until a certificate
for the shares has been delivered.

        An Option granted under the Plan may be exercised for any lesser number
of shares than the full amount for which it could be exercised.  Such a partial
exercise of an Option shall not affect the right to exercise the Option from
time to time in accordance with the Plan for the remaining shares subject to
the Option.

8.      TERMINATION OF OPTIONS

        An Option granted under the Plan shall be considered terminated in
whole or in part, to the extent that, in accordance with the provisions of the
Plan and such Option, it can no longer be exercised for any shares originally
subject to the Option.

9.      ADJUSTMENTS UPON CHANGES IN CAPITALIZATION

        In the event of any change in the outstanding Class B Stock of the
Company by reason of a stock dividend, stock split, stock consolidation,
recapitalization, reorganization, merger, split up or the like, the shares
available for purposes of the Plan, or under option in outstanding option
agreements pursuant to the Plan (and the option price under such agreements)
shall be appropriately adjusted so as to preserve, but not increase, the
benefits of the Plan to the Company and the benefits to the holders of such
Options; provided, however, that for any Incentive Stock Options, in the case
of a corporate merger, consolidation, acquisition of property or stock,
separation, reorganization or liquidation, the excess of the aggregate fair
market value of the shares subject to any Options immediately after such event
over the aggregate option price of such shares is not more than the excess





                                     -8-
<PAGE>   9


of the aggregate fair market value of all shares subject to such Options
immediately before such event over the aggregate option price of such shares.

        Adjustments under this Section shall be made by the Board or the
Committee, whose determination as to what adjustments shall be made and the
extent thereof, shall be final, binding and conclusive.

10.     COMPLIANCE WITH SECURITIES LAWS AND OTHER REQUIREMENTS

        No certificate(s) for shares shall be executed and delivered upon
exercise of an Option until the Company shall have taken such action, if any,
as is then required to comply with the provisions of the Securities Act of
1933, as amended, the North Carolina Uniform Securities Act, as amended, any
other applicable state securities law(s) and the requirements of any exchange
on which the Class B Stock may, at the time, be listed.

        In the case of the exercise of an Option by a person or estate
acquiring the right to exercise the Option by bequest or inheritance, the Board
or the Committee may require reasonable evidence as to the ownership of the
Option and may require such consents and releases of taxing authorities as it
may deem advisable.

11.     NO RIGHT TO EMPLOYMENT

        Neither the adoption of the Plan nor its operation, nor any document
describing or referring to the Plan, or any part thereof, shall confer upon any
employee participant under the Plan any right to continue in the employ of the
Company, or shall in any way affect the right and power of the Company to
terminate the employment or position with the Company of any participant under
the Plan at any time with or without assigning a reason therefor, to the same
extent as the Company might have done if the Plan had not been adopted.

12.     EFFECTIVE DATE OF THE PLAN

        The Plan was adopted by the Board on November 16, 1995, and shall be
effective until November 16, 2005, after which time no Option shall be granted,
but such termination shall not affect any Option previously granted under the
Plan.

13.     Stock Certificate Legend.  Each stock certificate issued for options
intended to be Incentive Stock Options shall bear the following legend:

        THE SHARES REPRESENTED BY THIS CERTIFICATE WERE ACQUIRED PURSUANT TO A
        STOCK OPTION PLAN AND WERE INTENDED TO BE A QUALIFIED OPTION AS SET

                _____);

        (2)     This Option will vest and become exercisable according to the
                schedule set forth in the Plan;

        (3)     Once exercisable, this Option may be exercised until
                _________________, _____,       subject to the terms and
                conditions of the Plan, a copy of which is attached hereto and

                subject to the Plan and shall be construed in accordance with
                the Plan.

        (4)     This Option is (is not) intended to be treated as an "incentive
                stock option" for purposes of Section 422 of the Internal
                Revenue Code.

        (5)     To exercise this Option, the holder must deliver written notice
                of the decision to do so and at the same time tender to the

        (6)     The exercise of this Option shall be subject to the condition
                that, if at any time the Board or the Committee (as defined in

                satisfaction of withholding tax or other withholding
                liabilities under any state or federal law is necessary or
                desirable as a condition of, or in connection with, such
                exercise or the delivery or purchase of shares pursuant
                thereto, then in such event, the exercise of the option shall
                not be effective unless such withholding tax or other
                withholding liabilities shall have been satisfied in a manner
                acceptable to the Company, which may include the withholding by
                the Company of shares of Class B Stock to be issued upon
                exercise of an Option having a fair market value equal to the
                required withholding amount.

the Plan.

                      APPLIED ANALYTICAL INDUSTRIES, INC.

                             1996 STOCK OPTION PLAN

                              AMENDED AND RESTATED


1.      PURPOSE

        The purpose of the Applied Analytical Industries, Inc. 1996 Stock
Option Plan (the "Plan") is to promote the growth and profitability of Applied
Analytical Industries, Inc. (the "Company") and its subsidiaries
("Subsidiaries") from time to time by increasing the personal participation of
officers and key employees in the financial performance of the Company and by
providing such officers and key employees with an equity opportunity in the
Company.  This purpose will be achieved through the grant of stock options
("Options") to purchase shares of Class B Non-Voting Common Stock of the
Company (the "Class B Stock") subject to restrictions on transfer or such other
restrictions as the administrators of the Plan may determine.

2.      ADMINISTRATION

        The Plan will be administered by the Company's Board of Directors (the
"Board"); provided, however, that from and after the registration of any class
of equity securities of the Company pursuant to Section 12 of the Securities
Exchange Act of 1934, as amended, if the Board includes members who are not
"disinterested persons" (as defined in Rule 16b-3 promulgated under the
Securities Exchange Act of 1934, as amended, or any applicable successor rule
or regulation ) or "outside directors" (as defined in Section 162(m) of the
Internal Revenue Code of 1986, as amended, and the regulations thereunder),
then all authority of the Board under the Plan shall be exercised by a
committee of the Board (the "Committee") composed solely of members thereof who
are both "disinterested persons" and "outside directors" (as so defined).

        The Board or the Committee shall have complete authority to: (i)
interpret all terms and provisions of the Plan consistent with law; (ii) select
from the group of officers and key employees eligible to participate in the
Plan the officers and key employees to whom Options shall be granted; (iii)
within the limits established herein, determine the number of shares to be
subject to and the exercise price of, each Option; (iv) prescribe the form of
instrument(s) evidencing Options granted under the Plan; (v) determine the time
or times at which Options shall be granted to officers or key employees; (vi)
provide, if appropriate, for the exercisability of Options in installments or
subject to specified conditions; (vii) determine the method of exercise of
Options; (viii) adopt, amend and rescind general and special rules and
regulations for the Plan's administration; and (ix) make all other



<PAGE>   2


determinations necessary or advisable for the administration of the Plan.

        Any action which the Board or the Committee is authorized to take may
be taken without a meeting if all the members of the Board or the Committee
sign a written document authorizing such action to be taken, unless different
provision is made by the By-Laws of the Company or by resolution of the Board
or the Committee.

        The Board or the Committee may designate selected Board or Committee
members or certain employees of the Company to assist the Board or the
Committee in the administration of the Plan and may grant authority to such
persons to execute documents, including Options, on behalf of the Board or the
Committee.

        No member of the Board or the Committee or employee of the Company
assisting the Board or the Committee pursuant to the preceding paragraph shall
be liable for any action taken or determination made in good faith.

3.      STOCK SUBJECT TO PLAN

        The stock to be offered under the Plan shall be authorized but unissued
shares of Class B Stock.  An aggregate of 3,918 shares of Class B Stock are
reserved for issuance upon exercise of Options.  Any or all of the Options
granted under Section 4 hereof may, at the Board or the Committee's discretion,
be intended to qualify as incentive stock options ("Incentive Stock Options")
under Section 422 of the Internal Revenue Code of 1986, as amended (the
"Code").  The number of shares reserved under the Plan may be adjusted to
reflect any change in the capitalization of the Company as contemplated by
Section 9 hereof and occurring after the adoption of the Plan.  The Board or
the Committee will maintain records showing the cumulative total of all shares
subject to Options outstanding under the Plan.

4.      OPTION AWARDS

        (a)     Eligibility and Factors Considered in Granting Options

        The grant of Options under this Section 4 shall be limited to those
officers and key employees of the Company or any of its Subsidiaries who have
the greatest contribution to the Company's long-term performance and are
selected by the Board or the Committee.  In making any determination as to the
officer(s) and key employee(s) to whom Options shall be granted under this
Section 4 and as to the number of shares to be subject thereto, the Board or
the Committee shall take into account, in each case, the level and
responsibility of the person's position, the level of the person's performance,
the person's level of compensation, the assessed potential of the person and
such additional factors as the





                                     -2-
<PAGE>   3


Board or the Committee shall deem relevant to the accomplishment of the
purposes of the Plan.

        (b)     Allotment of Shares

        The Board or the Committee, in its sole discretion and subject to the
provisions of the Plan, may grant to participants eligible under this Section
4, on or after the date hereof, Options; provided, however, that prior to
January 1, 1997, the Board or the Committee may not grant Options pursuant to
the Plan exercisable in the aggregate for more than 1,667 shares of Class B
Stock.  Options may be, at the discretion of the Board or the Committee: (i)
Options that are intended to qualify as Incentive Stock Options; or (ii)
Options that are not intended to be Incentive Stock Options; or (iii) both of
the foregoing, if granted separately, and not in tandem.  Each Option granted
under the Plan must be clearly identified as to its status as an Incentive
Stock Option or not.

        Options granted under this Section 4 may be allotted to participants in
such amounts, subject to the limitations specified in the Plan, as the Board or
the Committee, in its sole discretion, may from time to time determine,
provided that no participant may be granted Options with respect to more than
2,000 shares of Class B Stock.

        In the case of Options intended to be Incentive Stock Options, the
aggregate fair market value (determined at the time of such Incentive Stock
Options' respective grants) of the shares with respect to which Incentive Stock
Options are exercisable for the first time by a participant hereunder during
any calendar year (under all plans taken into account pursuant to Section
422(d) of the Code) shall not exceed $100,000.  Options under this Section 4
not intended to qualify as Incentive Stock Options may be granted to any Plan
participant without regard to the Section 422(d) limitations.

        (c)     Time of Granting Options

        The date of grant of an Option under this Section 4 shall be, for all
purposes, the date on which the Board or the Committee makes the determination
of granting such Option (each such date, a "Grant Date").  Notice of the
determination shall be given to each officer or key employee to whom an Option
is so granted under this Section 4 within a reasonable time after the Grant
Date.

        (d)     Exercise Price for Options

        The price per share at which each Option granted under this Section 4
may be exercised shall be such price as shall be determined by the Board or the
Committee at the time of grant based on such criteria as may be adopted by the
Board or the Committee at the time of grant in good faith, taking into account,
in each case,





                                     -3-
<PAGE>   4


the market price of the common stock, the level and responsibility of the
person's position, the level of the person's performance, the person's level of
compensation, the assessed potential of the person, and such additional factors
as the Board or the Committee shall deem relevant to the accomplishment of the
purposes of the Plan; provided, however, that in no event shall the exercise
price per share of an Option be less than 100% of the fair market value of the
Company's shares of common stock on the Grant Date for such Option unless such
grant is approved by all directors and in no event shall be less than 75% of
the fair market value of the Company's shares of common stock on the Grant Date
for such Option.  In the case of an Option intended to qualify as an Incentive
Stock Option, the price per share shall not be less than 100% (or 110% for
owners of more than 10% of the total combined voting power of all classes of
stock of the Company or any Subsidiary) of the fair market value of the Common
Stock on the Grant Date for such Option.

        If the Company's shares of Common Stock are:

        (1)     actively traded on any national securities exchange or NASDAQ
system that reports their sales prices, fair market value shall be the average
of the high and low sales prices per share on any Grant Date;

        (2)     otherwise traded over the counter, fair market value shall be
the average of the final bid and asked prices for the shares of Common Stock as
reported for any Grant Date; or

        (3)     not traded, the Board or the Committee shall consider any
factor or factors that it believes affects fair market value, and shall
determine fair market value without regard to any restriction other than a
restriction that by its terms will never lapse.

        (e)     Term of Options

        The term of each Option granted under this Section 4 shall be
established by the Board or the Committee, but shall not exceed 10 years (or 5
years for owners of more than 10% of the total combined voting power of all
classes of stock of the Company or of a Subsidiary) from the Grant Date for
such Option.

        (f)     Cancellation and Replacement of Options

        The Board or the Committee may at any time or from time to time permit
the voluntary surrender by the holder of any outstanding Option granted under
this Section 4 where such surrender is conditioned upon the granting under this
Section 4 to such holder of new Option(s) for such number of shares as the
Board or the Committee shall determine, or may require such a voluntary
surrender as a condition precedent to the grant under this Section 4 of new
Option(s) to such holder.





                                     -4-
<PAGE>   5


        The Board or the Committee shall determine the terms and conditions of
any such new Option(s), including their exercise price and the periods during
which they may be exercised, subject to and in accordance with the provisions
of the Plan, all or any of which may differ from the terms and conditions of
the Option(s) surrendered.  Any such new Option(s) shall be subject to all the
relevant provisions of the Plan.

        The shares subject to any Option so surrendered or terminated shall no
longer be charged against the limitation or limitations provided in Section 3
of the Plan and may thereafter become the subject of new Option grants under
the Plan.

        The granting of new Option(s) in connection with the surrender of
outstanding Option(s) under the Plan shall be considered for the purposes of
the Plan as the grant of new Option(s) and not an alteration, amendment or
modification of the Plan or of the Option(s) being surrendered.

        (g)     Vesting

        Options shall vest as follows:

the purposes of the Plan, an "Acquisition Transaction" shall mean and include
the following:

                 (i)      The consummation of a tender offer or exchange offer
                          for the ownership of securities of the Company
                          representing 51 % or more of the combined voting
                          powers of the Company's then outstanding voting
                          securities;

                (ii)      The adoption by the Company's stockholders of a plan

                          or consolidation of the Company with another
                          corporation (other than an affiliate of the Company
                          within the meaning of the Securities Exchange Act of
                          1934, as amended) and as a result of such merger

<PAGE>   6


                          or consolidation less than 75% of the outstanding
                          voting securities of the surviving or resulting
                          corporation would then be owned in the aggregate by
                          the former stockholders of the Company; or

               (iii)      The transfer by the Company of substantially all of
                          its assets to another corporation or entity which is
                          not a wholly owned subsidiary of the Company.

5.       NON-TRANSFERABILITY

         An Option granted to a participant under the Plan shall not be
transferable by him or her except: (i) by will; (ii) by the laws of descent and
distribution; or (iii) pursuant to a qualified domestic relations order as
defined by the Code or in Title I of the Employee Retirement Income Security
Act, or the rules thereunder.  In the case of an Option intended to be an
Incentive Stock Option, such Option shall not be transferable by a participant
other than by will or the laws of descent and distribution and during the
optionee's lifetime shall be exercisable only by him or her.

6.       EXERCISABILITY OF OPTIONS

         Subject to the provisions of the Plan, Options granted under Section 4
hereof shall be exercisable at such time or times after the Grant Date to the
extent such Options are vested.

         Any Option shall terminate in full (whether or not previously
exercisable) prior to the expiration of its term on the date the optionee
ceases to be an employee of the Company or any Subsidiary of the Company,
unless (i) the optionee shall (a) die while an employee of the Company or such
Subsidiary, in which case the participant's legatee(s) under his or her last
will or the participant's personal representative or representatives may
exercise all or part of the previously unexercised portion of such Option at
any time within one year, but not beyond the expiration of its term, after the
participant's death to the extent the optionee could have exercised the Option
immediately prior to his or her death, (b) become permanently or totally
disabled within the meaning of section 22(e)(3) of the Code (or any successor
provision) while an employee of the Company or such Subsidiary, in which case
the participant or his or her personal representative may exercise the
previously unexercised portion of such Option at any time within one year, but
not beyond the expiration of its term, after termination of his or her
employment or directorship to the extent the optionee could have exercised the
Option immediately prior to such termination, or (c) resign or retire after age
62 with the consent of the Company, in which case the participant may exercise
the previously unexercised portion of such Option at any time within six
months, but not beyond the expiration of its term, after the participant's
resignation or retirement to the extent the optionee could have exercised the
Option immediately prior to such





                                     -6-
<PAGE>   7


resignation or retirement, or (ii) the Board or the Committee shall determine
otherwise.

 In no event may an Option be exercised after the expiration of its fixed term.

7.       METHOD OF EXERCISE

         Each Option granted under the Plan shall be deemed exercised when the
holder (a) shall indicate the decision to do so in writing delivered to the
Company, (b) shall at the same time tender to the Company payment in full of
the exercise price for the shares for which the Option is exercised, which
payment may be made in cash, and (c) shall comply with such other reasonable
requirements as the Board or the Committee may establish; provided that in
order to enable an optionee (including but not limited to officers) to exercise
options granted under the Plan, the Board or the Committee may determine, in
the exercise of its discretion, to (i) cause the Company to lend money or-
other property to such optionee upon such terms and conditions and in such
amounts as the Board or the Committee may determine, (ii) grant such optionee
permission to pay the exercise price in installments, or to accept such
optionee's note as whole or partial payment, (iii) permit such optionee to
repay loans made by the Company to such optionee for the exercise of options
with issued and outstanding shares of common stock, (iv) grant such optionee
permission to pay the exercise price by delivering for cancellation Options
having an aggregate value (calculated by subtracting the exercise price per
share from the fair market value of a share of Class B Stock) equal to the
total amount of the exercise price, or (v) provide such financial assistance to
such optionee as the Board or the Committee determines to be desirable.  The
exercise of any option granted under the Plan may be made subject to the
condition that, if at any time the Board or the Committee shall determine, in
its discretion, that the satisfaction of withholding tax or other withholding
liabilities under any state or federal law is necessary or desirable as a
condition of, or in connection with, such exercise or the delivery or purchase
of shares pursuant thereto, then in such event, the exercise of the option
shall not be effective unless such withholding tax or other withholding
liabilities shall have been satisfied in a manner acceptable to the Company,
which may include the withholding by the Company of shares of Common Stock to
be issued upon exercise of an Option having a fair market value equal to the
required withholding amount.  With respect to the foregoing sentences, the
value of the shares of Common Stock shall be the fair market value determined
in accordance with Section 4(d) of the Plan as of the day of such payment or
withholding.

         No person, estate or other entity shall have any of the rights of a
shareholder with reference to shares subject to an Option until a certificate
for the shares has been delivered.





                                     -7-
<PAGE>   8


         An Option granted under the Plan may be exercised for any lesser
number of shares than the full amount for which it could be exercised.  Such a
partial exercise of an Option shall not affect the right to exercise the Option
from time to time in accordance with the Plan for the remaining shares subject
to the Option.

8.       TERMINATION OF OPTIONS

         An Option granted under the Plan shall be considered terminated in
whole or in part, to the extent that, in accordance with the provisions of the
Plan and such Option, it can no longer be exercised for any shares originally
subject to the Option.

9.       ADJUSTMENTS UPON CHANGES IN CAPITALIZATION

         In the event of any change in the outstanding Common Stock of the
Company by reason of a stock dividend, stock split, stock consolidation,
recapitalization, reorganization, merger, split up or the like, the shares
available for purposes of the Plan or under option in outstanding option
agreements pursuant to the Plan (and the option price under such agreements)
shall be appropriately adjusted so as to preserve, but not increase, the
benefits of the Plan to the Company and the benefits to the holders of such
Options; provided, however, that for any Incentive Stock Options, in the case
of a corporate merger, consolidation, acquisition of property or stock,
separation, reorganization or liquidation, the excess of the aggregate fair
market value of the shares subject to any Options immediately after such event
over the aggregate option price of such shares is not more than the excess of
the aggregate fair market value of all shares subject to such Options
immediately before such event over the aggregate option price of such shares.

         Adjustments under this Section shall be made by the Board or the
Committee, whose determination as to what adjustments shall be made and the
extent thereof, shall be final, binding and conclusive.

10.      COMPLIANCE WITH SECURITIES LAWS AND OTHER REQUIREMENTS

         No certificate(s) for shares shall be executed and delivered upon
exercise of an Option until the Company shall have taken such action, if any,
as is then required to comply with the provisions of the Securities Act of
1933, as amended, the North Carolina Uniform Securities Act, as amended, any
other applicable state securities law(s) and the requirements of any exchange
on which the Class B Stock may, at the time, be listed.

         In the case of the exercise of an Option by a person or estate
acquiring the right to exercise the Option by bequest or inheritance, the Board
or the Committee may require reasonable evidence as to the ownership of the
Option and may require such consents and releases of taxing authorities as it
may deem advisable.

<PAGE>   9


11.      NO RIGHT TO EMPLOYMENT

         Neither the adoption of the Plan nor its operation, nor any document
describing or referring to the Plan, or any part thereof, shall confer upon any
employee participant under the Plan any right to continue in the employ of the
Company, or shall in any way affect the right and power of the Company to
terminate the employment or position with the Company of any participant under
the Plan at any time with or without assigning a reason therefor, to the same
extent as the Company might have done if the Plan had not been adopted.

12.      EFFECTIVE DATE OF THE PLAN

         The Plan was adopted by the Board on November 16, 1995, and shall be
effective until November 16, 2005, after which time no Option shall be granted,
but such termination shall not affect any Option previously granted under the
Plan.

13.      STOCK CERTIFICATE LEGEND.  Each stock certificate issued for options
intended to be Incentive Stock Options shall bear the following legend:

         THE SHARES REPRESENTED BY THIS CERTIFICATE WERE ACQUIRED PURSUANT TO A
         STOCK OPTION PLAN AND WERE INTENDED TO BE A QUALIFIED OPTION AS SET

                 herein by reference.  This Option is granted subject to the
                 Plan and shall be construed in accordance with the Plan.

         (4)     This Option is (is not) intended to be treated as an
                 "incentive stock option" for purposes of Section 422 of the
                 Internal Revenue Code.

         (5)     To exercise this Option, the holder must deliver written
                 notice of the decision to do so and at the same time tender to

                 satisfaction of withholding tax or other withholding
                 liabilities under any state or federal law is necessary or
                 desirable as a condition of, or in connection with, such
                 exercise or the delivery or purchase of shares pursuant
                 thereto, then in such event, the exercise of the option shall
                 not be effective unless such withholding tax or other
                 withholding liabilities shall have been satisfied in a manner
                 acceptable to the Company, which may include the withholding
                 by the Company of shares of Class B Stock to be issued upon
                 exercise of an Option having a fair market value equal to the
                 required withholding amount.

dated November 17, 1995 between Waters and Sancilio and (iv) the purchase of
shares of Common Stock by Sancilio pursuant to Section 11 of the Voting Trust
Agreement, the form of which is attached as Exhibit D to such Waters-Sancilio
Shareholders' Agreement.

         SECTION 2.       Methodology for Calculations.  For purposes of this
Agreement, the Sale of a Common Stock Equivalent shall be treated as the Sale
of the shares of Common Stock into which such Common Stock Equivalent can be
converted, exchanged or exercised.  Except as otherwise provided in this
Agreement, for purposes of all calculations under this Agreement (including,
without limitation, calculations to determine the ownership of Common Stock of
any Stockholder and the percentage of outstanding Common Stock owned by any
Stockholder), all Series A Preferred Stock (but no other Common Stock
Equivalents) shall be treated as having been converted, exchanged or exercised.

         SECTION 3.       Limitations on Sales of Stock by Stockholders.  (a)
Subject to the remaining subsections of this Section 3, each Stockholder shall
not Sell any Stock, whether owned on the date hereof or acquired hereafter,
other than:

                     (i)   by Sale in accordance with Sections 4, 5 and 6
hereof;

                    (ii)   by Sale pursuant to any of the Waters Puts;

                   (iii)   any Waters-Sancilio Transaction;

                    (iv)   by Sale to an Affiliate; or

                     (v)   in a Public Sale.

         (b)      In addition to the restrictions set forth in paragraph (a)
above, no Investor shall Sell any Stock for a period of two (2) years from the
date hereof (the "Mandatory Holding Period"); provided, however, that the
foregoing restriction shall not apply to any Sale (i) by an Other Stockholder
to a Section 5 Offeror, a Section 6 Offeror or a Buying Stockholder, as the
case may be, pursuant to Section 5, 6 or 7 of this Agreement, (ii) by a GSCP
Party to another GSCP Party or an Affiliate of a GSCP Party (a "GSCP
Affiliate"), (iii) by any other Investor to an Affiliate thereof, or (iv) which
is approved by the Corporation and by the holders of at least 70% of the then
outstanding Voting Shares (as defined below) voting as a single class
(excluding for purposes of this calculation all Voting Shares Beneficially
Owned by the proposed transferor and its Affiliates), which consent may be
granted or withheld in the sole





                                      -3-
<PAGE>   4

discretion of the Corporation and such voting shareholders.  "Voting Shares"
shall mean all voting securities of the Corporation (including, without
limitation, any shares of Class A Common Stock and Series A Preferred Stock).

         (c)      In addition to the restrictions set forth in paragraph (a)
and (b) above, from and after the termination of the Mandatory Holding Period,
no Investor shall Sell any Stock to any Competitor (except for any Sale by an
Other Stockholder to a Section 5 Offeror, a Section 6 Offeror or a Buying
Stockholder, as the case may be, pursuant to Section 5, 6 or 7 of this
Agreement), unless such Sale is approved by the Corporation and by the holders
of 70% of the then outstanding Voting Shares voting as a single class
(excluding for purposes of this calculation all Voting Shares Beneficially
Owned by the proposed transferor and its Affiliates), which consent may be
granted or withheld in the sole discretion of the Corporation and such voting
shareholders.

         (d)      Anything contained herein to the contrary notwithstanding,
any transferee of Stock (other than a transferee of a Public Sale) who is not a
Stockholder shall upon consummation of, and as a condition to, such Sale (A)
execute, and agree to be bound by the terms of, this Agreement and shall
thereafter be deemed a Stockholder for all purposes of this Agreement, (B)
execute and deliver a certificate in a form reasonably satisfactory to the
Corporation in which such person certifies that (I) it is purchasing the Stock
for its own account, for investment and not with a view to the distribution
thereof and (II) that such Sale is otherwise being made in compliance with all
applicable federal and state law (including, without limitation, federal and
state securities laws and "blue sky" laws), (C) execute and deliver a
certificate to the Corporation substantially in the form of Exhibit A hereto in
which such person certifies either (i) that such person is not a Competitor of
the Corporation or (ii) that such person is purchasing Stock in compliance with
the provisions of  Section 3(c) hereof, and (D) execute and deliver a
Non-Competition Agreement substantially in the form of Exhibit B hereto or such
other form which is acceptable to the Corporation (unless such transferee is a
Competitor of the Corporation and such Sale of Stock is made in accordance with
the provisions of Section 3(c), in which case the transferee shall not be
obligated to execute and deliver a Non-Competition Agreement).  Notwithstanding
any permitted transfer of Stock to a Person, the Corporation shall not be
obligated to disclose any confidential information relating to the Corporation
to such Person until such Person executes a Non-Disclosure Agreement
substantially in the form of Exhibit C hereto or such other form which is
acceptable to the Corporation.

         SECTION 4.        Rights of First Offer.  In addition to and not in
limitation of any other restrictions on Sales of Stock contained in this
Agreement, any Sale by a Stockholder (other than a Waters-Sancilio Transaction
or pursuant to any of the Waters Puts) shall be solely for cash consideration
and shall be consummated only in accordance with the following procedures:

         (a)      The selling Stockholder shall first deliver to the
Corporation a written notice (a "Section 4 Offer Notice"), which shall (i)
state the selling Stockholder's intention to sell Stock to one or more Persons,
the amount and type of Stock to be sold (the "Subject Stock"), the purchase
price therefor and a summary of the other material terms of the proposed sale
and (ii) offer the Corporation and the Other Stockholders the option to acquire
all or a portion of such Subject Stock upon the terms and subject to the
conditions of the proposed Sale as set forth in the Section 4 Offer Notice (the
"Section 4 Offer"), provided that such Section 4 Offer may provide that it must
be accepted by the Corporation and the Other Stockholders on an all or nothing
basis (an "All or Nothing Sale").  The Section 4 Offer shall remain open and
irrevocable for the periods set forth below (and, to the extent the Section 4
Offer is accepted during such periods, until the consummation of the sale
contemplated by the Section 4 Offer).  The





                                      -4-
<PAGE>   5

Corporation shall have the right and option, for a period of 30 days after
delivery of the Section 4 Offer Notice (the "Section 4(a) Acceptance Period"),
to accept all or any part of the Subject Stock at the purchase price and on the
terms stated in the Section 4 Offer Notice; provided, however, that, if the
Section 4 Offer contemplated an All or Nothing Sale, the Corporation may
accept, during the Section 4(a) Acceptance Period, all, but not less than all,
of the Subject Stock, at the purchase price and on the terms stated in the
Section 4 Offer Notice.  Such acceptance shall be made by delivering a written
notice to the selling Stockholder and each of the Other Stockholders within the
Section 4(a) Acceptance Period.

         (b)      If the Corporation shall fail to accept all of the Subject
Stock offered for sale pursuant to, or shall reject in writing, the Section 4
Offer (the Corporation being required to notify in writing the selling
Stockholder and each of the Other Stockholders of its rejection or failure to
accept in the event of the same), then, upon the earlier of the expiration of
the Section 4(a) Acceptance Period or the giving of such written notice of
rejection or failure to accept such offer by the Corporation, each Other
Stockholder shall have the right and option, for a period of 30 days thereafter
(the "Section 4(b) Acceptance Period"), to accept all or any part of the
Subject Stock so offered and not accepted by the Corporation (the "Refused
Stock") at the purchase price and on the terms stated in the Section 4 Notice;
provided, however, that, if the Section 4 Offer contemplated an All or Nothing
Sale, the Other Stockholders, in the aggregate, may accept, during the Section
4(b) Acceptance Period, all, but not less than all, of the Subject Stock, at
the purchase price and on the terms stated in the Section 4 Offer Notice.  Such
acceptance shall be made by delivering a written notice to the Corporation and
the selling Stockholder within the Section 4(b) Acceptance Period specifying
the maximum number of shares such Other Stockholder will purchase (the "First
Offer Shares").  If, upon the expiration of the Section 4(b) Acceptance Period,
the aggregate amount of First Offer Shares exceeds the amount of Refused Stock,
the Refused Stock shall be allocated among the Other Stockholders as follows:
(i) First, each Stockholder shall be entitled to purchase no more than its
Proportionate Percentage of Refused Stock; (ii) Second, if any shares of
Refused Stock have not been allocated for purchase pursuant to (i) above (the
"Remaining Shares"), each Stockholder (an "Oversubscribed Stockholder") which
had offered to purchase a number of shares of Refused Stock in excess of the
amount of stock allocated for purchase to it in accordance with previous
allocations of such shares of Refused Stock, shall be entitled to purchase an
amount of Remaining Shares equal to no more than its Proportionate Percentage
(treating only Oversubscribed Stockholders as Stockholders for these purposes)
of the Remaining Shares; and (iii) Third, the process set forth in (ii) above
shall be repeated with respect to any shares of Refused Stock not allocated for
purchase until all shares of Refused Stock are allocated for purchase.

         (c)      If effective acceptance shall not be received pursuant to
Sections 4(a) and 4(b) above with respect to all of the Subject Stock offered
for sale pursuant to the Section 4 Offer Notice, then the selling Stockholder
may Sell all or any portion of the Stock so offered for sale and not so
accepted, at a price not less than the price, and on terms not more favorable
to the purchaser thereof than the terms, stated in the Section 4 Offer Notice
at any time within 90 days after the expiration of the Section 4(b) Acceptance
Period (the "Sale Period").  To the extent the selling Stockholder Sells all or
any portion of the Stock so offered for sale during the Sale Period, the
selling Stockholder shall promptly notify the Corporation, and the Corporation
shall promptly notify the Other Stockholders, as to (i) the number of shares of
Stock, if any, that the selling Stockholder then owns, (ii) the number of
shares of Stock that the selling Stockholder has sold, (iii) the terms of such
Sale and (iv) the name of the owner(s) of any shares of Stock sold.  In the
event that all of the Stock is not sold by the selling Stockholder during the
Sale Period, the right of the selling Stockholder to Sell such unsold Stock
shall expire and the obligations of this Section 4 shall be reinstated;
provided, however, that, in the event that the selling Stockholder determines,
at any time during the Sale Period, that the sale of all of the Stock on the
terms set forth in





                                      -5-
<PAGE>   6

the Section 4 Offer Notice is impractical, the selling Stockholder may
terminate the offer and reinstate the procedure provided in this Section 4
without waiting for the expiration of the Sale Period.

         (d)      All Sales of Subject Stock to the Corporation and/or the
Other Stockholders subject to any one Section 4 Offer Notice  shall be
consummated contemporaneously at the offices of the Corporation on the later of
(i) a mutually satisfactory business day within 30 days after the expiration of
the Section 4(b) Acceptance Period or (ii) the fifth business day following the
expiration or termination of all waiting periods under the Hart-Scott-Rodino
Antitrust Improvements Act of 1976, as amended ("HSR"), applicable to such
sales, or at such other time and/or place as the parties to such sales may
agree.  The delivery of certificates or other instruments evidencing such
Subject Stock duly endorsed for transfer shall be made on such date against
payment of the purchase price for such Subject Stock.

         (e)      Anything contained herein to the contrary notwithstanding,
the selling Stockholder shall, in addition to complying with the provisions of
this Section 4 in the event of a proposed sale of Stock, comply with the
provisions of Section 5 and 6 (if applicable) hereof.

         (f)      The requirements of this Section 4 shall not apply to (i) any
Sale of Stock by a Stockholder to an Affiliate of such Stockholder; provided,
however that the requirements of this Section 4 shall apply to any Sale of
Stock by Waters, Sancilio or any of their Affiliates to a Joint Affiliate, (ii)
any Sale of Stock (by an Other Stockholder to a Section 5 Offeror) pursuant to
Section 5 of this Agreement, (iii) any Sale of Stock which is a Public Sale,
and (iv) any other Sale as to which the Corporation and the Stockholders waive
compliance with this Section 4.

         SECTION 5.        Tag-Along Rights.  (a) Subject to Section 5(d) and
except for any Sale of Stock pursuant to clause (ii), (iii), (iv) or (v) of
Section 3(a) hereof or between Waters (or any of Water's Affiliates) and
Sancilio (or any of Sancilio's Affiliates), each Stockholder shall not, alone
or in concert with any other Stockholders, in any transaction or series of
transactions, Sell any Stock to another Person or Group if, after giving effect
to such Sale, such Person or Group together with its Affiliates would
Beneficially Own more than 50% in the aggregate of either of the then total
outstanding (A) Voting Shares or (B) Common Stock, except in accordance with
the following procedures:

         (b)(i)   The selling Stockholder shall first deliver to each Other
Stockholder a written notice (the "Section 5 Notice"), which shall specifically
identify the identity of the proposed transferee (the "Section 5 Offeror"), the
amount and type of Stock being Sold, the purchase price therefor, and a summary
of the other material terms and conditions of the proposed Sale, and shall
contain an offer (the "Section 5 Offer") by the Section 5 Offeror to each Other
Stockholder, which shall be irrevocable for a period of 15 days after the later
of delivery thereof and the expiration of the Section 4(b) Acceptance Period,
to the extent applicable (the "Section 5 Period"), to purchase all of such
Other Stockholder's Stock at the Section 5 Purchase Price (as such term is
defined below), and upon the other terms offered by the Section 5 Offeror to
the selling Stockholder as set forth in the Section 5 Notice.  A copy of the
Section 5 Notice shall promptly be sent to the Corporation.  The Section 5
Offer may be accepted in whole or in part at the option of each of the Other
Stockholders.  Notice of an Other Stockholder's intention to accept a Section 5
Offer, in whole or in part, shall be evidenced by a writing signed by such
Other Stockholder and delivered to the Section 5 Offeror and the Corporation
prior to the end of the Section 5 Period, setting forth the number of shares
and class of Stock that such Other Stockholder elects to Sell.

                  (ii)     For purposes of this Agreement, the following terms
shall have the meanings set forth below:





                                      -6-

         "Per Share Price" means an amount equal to the greater of (i) the
         quotient obtained by dividing (A) the aggregate purchase price to be
         paid by the Section 5 Offeror in respect of the Stock proposed to be
         sold by the selling Stockholder as set forth in the Section 5 Notice
         by (B) the number of shares of Common Stock (including shares of
         Common Stock obtainable upon the conversion, exchange or exercise of
         Common Stock Equivalents) proposed to be sold by the selling
         Stockholder as set forth in the Section 5 Notice and (ii) the quotient
         of (A) the aggregate purchase price for all of the Stock purchased by
         the Section 5 Offeror during the nine-month period immediately prior
         to the date of the Section 5 Notice plus the aggregate purchase price
         to be paid by the Section 5 Offeror in respect of the Stock proposed
         to be sold by the selling Stockholder as set forth in the Section 5
         Notice, divided by (B) the aggregate number of shares of Common Stock
         (including shares of Common Stock obtainable upon the conversion,
         exchange or exercise of Common Stock Equivalents) purchased during
         such nine-month period plus the number of shares of Common Stock
         (including shares of Common Stock obtainable upon the conversion,
         exchange or exercise of Common Stock Equivalents) proposed to be sold
         by the selling Stockholder as set forth in the Section 5 Notice.

         "Section 5 Purchase Price" shall mean (i) with respect to a share of
         Common Stock, the Per Share Price and (ii) with respect to a Common
         Stock Equivalent, an amount equal to (A) the Per Share Price
         multiplied by (B) the number of shares of Common Stock issuable upon
         the conversion, exchange or exercise of such Common Stock Equivalent
         (subject to reduction, if appropriate, for the amount per share of the
         exercise or purchase price (if any) of such Common Stock Equivalent).

         (c)      All Sales of Stock to the Section 5 Offeror shall be
consummated contemporaneously at the offices of the Corporation on the later of
(i) a mutually satisfactory business day as soon as practicable, but in no
event more than 30 days after the expiration of the Section 5 Period or (ii)
the fifth business day following the expiration or termination of all waiting
periods under HSR applicable to such sales, or at such other time and/or place
as the parties to such sales may agree.  The delivery of certificates or other
instruments evidencing such Stock duly endorsed for transfer shall be made on
such date against payment of the purchase price for such Stock.

         (d)      Anything contained herein to the contrary notwithstanding,
any selling Stockholder shall, in addition to complying with the provisions of
this Section 5, comply with the provisions of Section 4 and 6 (if applicable)
hereof.

         SECTION 6.        Sancilio Tag-Along Rights.  (a) Subject to Section
6(d) and except for any Sale of Stock pursuant to clause (ii), (iii), (iv) or

concert, in any transaction or series of transactions, Sell to another Person
or Group an amount of Stock equal to 25% of the Common Stock held by Sancilio
as of the date hereof, except in accordance with the following procedures:

         (b)(i)   Sancilio shall first deliver to each Other Stockholder a

other material terms and conditions of the proposed Sale, and shall contain an
offer (the "Section 6 Offer") by the Section 6 Offeror to each Other
Stockholder, which shall be irrevocable for a period of 15 days after the later
of delivery thereof and the expiration of the Section 4(b) Acceptance Period,
to the extent applicable (the "Section 6 Period"), to purchase the number of
shares of Common Stock





                                      -7-
<PAGE>   8

obtained by multiplying (A) a fraction, the numerator of which is the number of
shares of Common Stock represented by the Stock proposed to be sold (as
indicated in the Section 6 Notice) and the denominator of which is the number
of shares of Common Stock Beneficially Owned by Sancilio as of the date of the
Section 6 Notice, times (B) the number of shares of Common Stock Beneficially
Owned by the Other Stockholder as of the date of the Section 6 Notice, at the
Section 6 Purchase Price (as such term is defined below) and upon the other

6 Notice.  A copy of the Section 6 Notice shall promptly be sent to the
Corporation.  The Section 6 Offer may be accepted in whole or in part at the
option of each of the Other Stockholders.  Notice of an Other Stockholder's
intention to accept a Section 6 Offer, in whole or in part, shall be evidenced
by a writing signed by such Other Stockholder and delivered to the Section 6
Offeror and the Corporation prior to the end of the Section 6 Period, setting
forth the number of shares and class of Stock that such Other Stockholder
elects to Sell.

                  (ii)     The Section 6 Purchase Price shall be calculated in
the same manner as the Section 5 Purchase Price except that references in the
definition of "Per Share Price" to (A) the selling Stockholder shall be a
reference to Sancilio and his affiliates and (B) the Section 5 Offeror and
Section 5 Notice, shall be a reference to the Section 6 Offeror and Section 6
Notice, respectively.

         (c)      All Sales of Stock to the Section 6 Offeror shall be
consummated contemporaneously at the offices of the Corporation on the later of
(i) a mutually satisfactory business day as soon as practicable, but in no
event more than 30 days after the expiration of the Section 6 Period or (ii)
the fifth business day following the expiration or termination of all waiting
periods under HSR applicable to such sales, or at such other time and/or place
as the parties to such sales may agree.  The delivery of certificates or other
instruments evidencing such Stock duly endorsed for transfer shall be made on
such date against payment of the purchase price for such Stock.

         (d)      Anything contained herein to the contrary notwithstanding,
Sancilio shall, in addition to complying with the provisions of this Section 6,
comply with the provisions of Sections 4 and 5 (if applicable) hereof.

         SECTION 7.        Bring-Along Rights.  (a) From and after the second
anniversary of the date hereof, if one or more Stockholders, whether alone or
in concert with any other Stockholder, propose to Sell to any Person or Persons
who are not, and following such Sale will not be, affiliated with any of such
Stockholder(s) (collectively, a "Buying Stockholder"), in a bona fide
arm's-length transaction or series of transactions, including by way of a
purchase agreement, tender offer, merger or other business combination
transaction or otherwise, 66% or more in aggregate of the then outstanding
Common Stock on a fully diluted basis (treating for purposes of these
calculations all Common Stock Equivalents as having been converted, exchanged
or exercised) (any such transaction being referred to herein as an "Exit
Sale"), then the selling Stockholders may elect to require all Other
Stockholders to Sell all shares of Stock Beneficially Owned by each of them
concurrently with such Exit Sale to such Buying Stockholder at the same
purchase price per share (and, in the case of Common Stock Equivalents, such
purchase price per share multiplied by the number of shares of Common Stock
issuable upon the conversion, exchange or exercise of such Common Stock
Equivalent subject to reduction, if appropriate, for the amount per share of
the exercise or purchase price (if any) of such Common Stock Equivalent) and
upon the same terms and subject to the conditions of the Exit Sale (except that
the Investors shall not be required to make any representations and warranties
relating to the Company or provide any indemnities with respect thereto).





                                      -8-
<PAGE>   9

         (b)      The rights set forth in Section 7(a) shall be exercised by
giving written notice (the "Section 7 Notice") to each Stockholder setting
forth in detail the terms of the proposed Sale and the proposed closing date of
the Exit Sale, which proposed date shall not be less than 15 or more than 60
days after such Section 6 Notice is delivered to the Stockholders.

         (c)      All Sales of Stock to the Buying Stockholder pursuant to this
Section 7 shall be consummated contemporaneously at the offices of the
Corporation on the later of (i) a business day not less than 15 or more than 60
days after the Section 7 Notice is delivered to the Stockholders or (ii) the
fifth business day following the expiration or termination of all waiting
periods under HSR applicable to such Sales, or at such other time and/or place
as the parties to such Sales may agree.  The delivery of certificates or other
instruments evidencing such Stock duly endorsed for transfer shall be made on
such date against payment of the purchase price for such Stock.

         (d)      Anything contained herein to the contrary notwithstanding,
the Selling Stockholders shall, in addition to complying with the provisions of
this Section 7, comply with the provisions of Section 4 hereof.

         SECTION 8.        Preemptive Rights.  (a) Except for Excluded
Securities (as hereinafter defined), the Corporation shall not issue, sell or
exchange, or agree to issue, sell or exchange (collectively, "Issue," and any
issuance, sale or exchange resulting therefrom, an "Issuance") (i) any shares
of the Corporation's capital stock, (ii) any other equity security of the
Corporation, including, without limitation, any options, warrants or other
rights to subscribe for, purchase or otherwise acquire any capital stock or
other equity security of the Corporation or (iii) any other security of the
Corporation that is convertible into or exchangeable for any equity security of
the Corporation (collectively, an "Equity Security") unless, in each case, the
Corporation shall have first given written notice (the "Offer Notice") to each
Stockholder which shall (a) state the Corporation's intention to sell any of
the Equity Securities, the amount to be issued, sold or exchanged, the terms of
such securities, the purchase price therefor and a summary of the other
material terms of the proposed issuance, sale or exchange and (b) offer (a
"Preemptive Offer") to Issue to each Stockholder such Stockholder's Pro Rata
Share (as defined below) of such securities (with respect to each Stockholder,
the "Offered Securities") upon the terms and subject to the conditions set
forth in the Offer Notice, which Preemptive Offer by its terms shall remain
open and irrevocable for a period of 30 days from the date it is delivered by
the Corporation to the Stockholder (and, to the extent the Preemptive Offer is
accepted during such 30 day period, until the closing of the sales contemplated
by the Preemptive Offer).  "Pro Rata Share" for the purposes of this Section
shall mean, the quotient of (i) the number of shares of Common Stock owned by
the Stockholder on the date of the Preemptive Offer divided by (ii) the total
number of shares of Common Stock issued and outstanding on the date of the
Preemptive Offer.

                  (b)      Notice of a Stockholder's intention to accept a
Preemptive Offer, in whole or in part, shall be evidenced by a writing signed
by the Stockholder and delivered to the Corporation prior to the end of the 30
day period of such Preemptive Offer (each, a "Notice of Acceptance"), setting
forth such portion of the Offered Securities that the Stockholder elects to
purchase.

                  (c)(i)   In the event that a Notice of Acceptance is not
given by a Stockholder in respect of all the Offered Securities, the
Corporation shall have 30 days following the earlier of (A) delivery of the
Notice of Acceptance or (B) the 30 day period referred to in clause (b) above,
if no Notice of Acceptance is delivered, to Issue all or any part of such
remaining Offered Securities not covered by the Notice of Acceptance to any
other person or persons, but only upon terms and conditions in all respects,





                                      -9-
<PAGE>   10

including, without limitation, unit price and interest rates, which are no more
favorable, in the aggregate, to such other person or persons or less favorable
to the Corporation than those set forth in the Preemptive Offer.

                  (ii)     If the Corporation does not consummate the Issuance
of all or part of the remaining Offered Securities to such other person or
persons within such period, the right provided hereunder shall be deemed to be
revived and such securities shall not be offered unless first reoffered to the
Stockholders in accordance with this Section 8.

                  (iii)    Upon the closing of the Issuance to such other
person or persons (the "Other Buyers") of all or part of the remaining Offered
Securities, the Stockholder shall purchase from the Corporation, and the
Corporation shall Issue to the Stockholder, the Offered Securities covered by
the Notice of Acceptance delivered to the Corporation by the Stockholder, on
the terms specified in the Preemptive Offer.  The purchase by the Stockholder
of any Offered Securities is subject in all cases to the execution and delivery
by the Corporation and the Stockholder of a purchase agreement relating to such
Offered Securities in form and substance similar in all material respects to
the extent applicable to that executed and delivered between the Corporation
and the Other Buyers.

         (d)      As used herein, "Excluded Securities" shall mean:  (i) up to

such Board of Directors of a Subsidiary shall cease to serve as a director of

        SECTION 15.  PharmComm Option.  (a) Schedule 15(a) hereto sets forth a
list of all persons who are currently stockholders of the Corporation and who
shall be issued securities of PharmComm, Inc. upon the capitalizaton thereof to
occur promptly following the date hereof (the "PharComm Stockholders"),
including the number of shares to be issued to such persons.

        (b)    The PharComm Stockholders are hereby granting the Corporation an
option (the "Option"), exercisable at any time after the date hereof and prior
to the Option Expiration Date (as defined below), to purchase all shares of
capital stock in PharmComm, Inc. to be acquired by them upon the capitalization
of PharmComm, Inc. (the "PharmComm Stock") at a per share price equal to the
Option Exercise Price (as defined below) in accordance with the terms of this
Section 15.  The Corporation shall exercise the Option (i) prior to the earlier
of a Qualified IPO and the Option Expiration Date (as defined below) unless,
with the consent of GSCP, it determines not to exercise the Option, and (ii)
from and after a Qualified IPO and prior to the Option Expiration Date, if the
directors of the Corporation (other than Sancilio and Waters) that are neither
employees of the Corporation nor otherwise affiliated with PharmComm, Inc.
determine that such exercise is advisable.  The Corporation shall exercise the
option by providing the PharmComm Stockholders written notice of such exercise
and the closing of such sale of shares (the "PharmComm Closing") shall occur
within five days after such exercise.  At the PharmComm Closing, each of the
PharmComm Stockholders shall deliver to the Corporation the shares of PharmComm
Stock being sold by them duly endorsed for transfer.  The Option shall
terminate on November 17, 1996 (the "Option Expiration Date").  With respect to
any share of PharmComm Stock, the Option Exercise Price shall mean the actual
price paid by the selling PharmComm Stockholder, as the case may be, for such
share of PharmComm Stock together with interest accruing on such amount at an
annual rate of 12% from the date such share of PharmComm stock was purchased
until the PharmComm Closing.

        (c)    From the date hereof and until the Option Expiration Date, the
PharmComm Stockholders shall cause PharmComm not to (i) pay, or set aside any
sums for the payment of, any dividends or make any distribution on, any shares
of its capital stock, (ii) sell, transfer, redeem, repurchase or otherwise
acquire any outstanding shares of its capital stock or (iii) suffer any
Encumbrance to exist on any outstanding shares of PharmComm Stock.

        SECTION 16.  Funding of 1995 Stock Options.  The Corporation has
adopted a 1995 Stock Option Plan (the "1995 Plan") pursuant to which it may
grant to employees options (each a "1995 Option") to purchase up to 1,917.3
shares of Common Stock.  Upon the exercise of any 1995 Option, the Corporation
shall promptly, but in no event later than two days after notice of such
exercise, notify Waters and Sancilio of such exercise (such notice, the "Option
Notice") and shall specify the amount of shares to be purchased under such
Option (the "Option Shares") and the exercise price per share (the "Option
Price").  Waters and Sancilio hereby agree that, within two days after receipt
of the Option Notice, they will sell to the Corporation, for cash, an amount of
shares of Class B Non-Voting Common Stock equal to the Option Shares at a price
per share equal to the Option Price.  The obligation of Waters and Sancilio
under this paragraph shall be joint and several, but as between them Waters
shall sell 45% and Sancilio shall sell 55% of the amount of such Option Shares.

        SECTION 17.  Legends.  Each certificate representing shares of Stock
shall bear a legend containing the following words:

        "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
        REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED.  THE





                                      -16-
<PAGE>   17

        SECURITIES HAVE BEEN ACQUIRED FOR INVESTMENT AND MAY NOT BE SOLD,
        TRANSFERRED OR OTHERWISE DISPOSED OF EXCEPT IN COMPLIANCE WITH SUCH
        ACT."

        "IN ADDITION, THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE
        SUBJECT TO THE RESTRICTIONS ON TRANSFER SET FORTH IN THE STOCKHOLDER
        AGREEMENT DATED AS OF NOVEMBER 17, 1995 BY AND AMONG APPLIED ANALYTICAL
        INDUSTRIES, INC. AND THE PARTIES THERETO, A COPY OF WHICH IS ON FILE IN
        THE OFFICE OF THE CORPORATION."

The requirement that the above securities legend be placed upon certificates
evidencing any such securities shall cease and terminate upon the earliest of
the following events:  (i) when such shares are transferred in an underwritten
public offering, (ii) when such shares are transferred pursuant to Rule 144
under the Securities Act or (iii) when such shares are transferred in any other
transaction if the seller delivers to the Corporation an opinion of its
counsel, which counsel and opinion shall be reasonably satisfactory to the
Corporation, or a "no-action" letter from the staff of the SEC, in either case
to the effect that such legend is no longer necessary in order to protect the
Corporation against a violation by it of the Securities Act upon any sale or
other disposition of such shares without registration thereunder.  The
requirement that the above legend regarding the Stockholder Agreement be placed
upon certificates evidencing any such securities shall cease and terminate upon
the termination of this Agreement.  Upon the occurrence of any event requiring
the removal of a legend hereunder, the Corporation, upon the surrender of
certificates containing such legend, shall, at its own expense, deliver to the
holder of any such shares as to which the requirement for such legend shall
have terminated, one or more new certificates evidencing such shares not
bearing such legend.

        SECTION 18.  Severability.  Whenever possible, each provision of this
Agreement shall be interpreted in such manner as to be effective and valid, but
if any provision of this Agreement is held to be invalid or unenforceable in
any respect, such invalidity or unenforceability shall not render invalid or
unenforceable any other provision of this Agreement.

        SECTION 19.  Governing Law.  This Agreement shall be governed by and
construed in accordance with the laws of the State of New York without giving
effect to the principles of conflicts of law.  Each of the parties hereto
hereby irrevocably and unconditionally consents to submit to the exclusive
jurisdiction of the courts of the State of New York and of the United States of
America, in each case located in the County of New York, for any action,
proceeding or investigation in any court or before any governmental authority

         1.4      Additional Issuances; Purchase Price Adjustment.

         (a)      In addition to and without limitation of all other
indemnities in this Agreement, in the event that the representation and
warranty set forth in the last sentence of Section 2.3 was not true when made,
the Corporation shall issue to the Investors (on a pro rata basis), at no cost
to the Investors, and as an adjustment to the purchase price paid by the
Investors per share of Series A Preferred Stock, an additional amount of Series
A Preferred Stock such that, if such issuance of additional Series A Preferred
Stock were made at the Closing, such representation and warranty would have
been true and accurate in all respects when made.

         (b)      If at the time of any required purchase price adjustment
pursuant to Section 1.4(a) all shares of Series A Preferred Stock have been
converted into shares of Common Stock (as defined in Section 2.3), the
Corporation shall promptly issue to the Investors (on a pro rata basis), at no
cost to the Investors and as an adjustment to the purchase price paid by the
Investors per share of Series A Preferred Stock, an additional amount and kind
of Common Stock equal to the amount and kind of Common Stock issuable upon the
conversion (based on the conversion ratio in effect at the time the last shares
of Series A Preferred Stock were converted into shares of Common Stock) of the
amount of Series A Preferred Stock which would have been issued with respect to
such purchase price adjustment pursuant to Section 1.4(a) if such purchase
price adjustment had been made immediately prior to the time the last shares of
Series A Preferred Stock were converted into shares of Common Stock (the "Final
Conversion Time").

         (c)      Any additional shares of Series A Preferred Stock and Common
Stock issued to the Investors pursuant to this Section 1.4 shall be treated as
if they were issued on the date hereof and shall reflect any dividends or other
distributions which would have accrued or have been payable with respect to and
the application of any anti-dilution, ratable treatment or similar provisions
(as set forth in the Certificate of Incorporation, applicable law or otherwise)
which would have been applicable to such shares of Series A Preferred Stock and
Common Stock had they been issued on the date hereof.

         (d)      In connection with any issuance of Series A Preferred Stock
pursuant to this Section 1.4, the Corporation shall reserve a sufficient number
of shares of Class A Voting Common Stock and Class B Non-Voting Common Stock
for issuance to the Investors upon the conversion of the shares of Series A
Preferred Stock so issued.  Any shares of Series A Preferred Stock or Common
Stock issued to the Investors pursuant to this Section 1.4 shall, when issued,
be validly issued and fully paid and nonassessable with no personal liability
attaching to the ownership thereof.

SECTION 2.        Representations and Warranties of the Corporation.  The
Corporation hereby represents and warrants to the Investors (other than Waters)
as of the date hereof as follows:

         2.1      Organization and Good Standing; Power and Authority;
Qualifications.  Each of the Corporation and Applied Analytical Industries
Italy, S.r.l. (collectively, the "AAI Entities" and each individually, an "AAI
Entity") (i) is a corporation duly organized, validly existing and in good
standing under the laws of its jurisdiction of incorporation, (ii) has all
requisite corporate power and authority to own, lease and operate its
properties and to carry on its business as presently conducted and as proposed
to be conducted and (iii) has all requisite corporate power and authority to
enter into and carry out the transactions contemplated by the Documents to
which it is a party.  Each AAI Entity is qualified to transact business as a
foreign corporation in, and is in good standing under the laws of, those
jurisdictions listed on Schedule 2.1 under its name, which jurisdictions
constitute all of the jurisdictions wherein the character of the property owned
or leased or the nature of the activities conducted by it makes such
qualification necessary, except jurisdictions in which the failure to be so
qualified would not have a material adverse effect on the condition (financial
or otherwise), results of operations, business or assets of the AAI Entities
taken as a whole (a "Material Adverse Effect").

         2.2      Authorization of the Documents.  The execution, delivery and
performance by the Corporation of each of the Documents have been duly
authorized by all requisite corporate action on the part of the Corporation,
and each of the Documents constitutes a legal, valid and binding obligation of
the Corporation, enforceable against the Corporation in accordance with its
terms except to the extent that enforceability may be limited by bankruptcy,
insolvency or other similar laws affecting creditors' rights generally, that
the remedy of specific performance and injunctive and other forms of equitable
relief may be subject to certain equitable defenses and to the discretion of
the court before which any proceeding therefor may be brought and that certain
indemnification provisions included in the Registration Rights Agreement may be
unenforceable as being contrary to public policy.

         2.3      Capitalization.  The authorized capitalization of the
Corporation immediately following the Purchase consists of:

         (a)      Preferred Stock.  1,000 shares of Preferred Stock, par value
$.01 per share ("Preferred Stock"), of which (i) 1,000  shares have been
designated Series A Preferred Stock and (ii) 883 shares of Series A Preferred
Stock are issued and outstanding.  The shares of Series A Preferred to be
issued and delivered in accordance with the terms of this Agreement will be
validly issued and fully paid and nonassessable when so issued and delivered.


                                       5

<PAGE>   17



         (b)      Common Stock.  155,000 shares of Common Stock, no par value
per share ("Common Stock"), of which (i) 5,000 shares have been designated
Class A Voting Common Stock and 150,000 shares have been designated Class B
Non-Voting Common Stock, and (ii) 3,532 shares of Class A Voting Common Stock
and 79,830.25 shares of Class B Common Voting Stock are issued and outstanding
and all such shares have been validly issued and are fully paid and
nonassessable.

         Schedule 2.3(a) hereto contains a list of (i) all holders of record of
capital stock of the Corporation, including the number of shares of capital
stock held by each such holder, and (ii) all outstanding warrants, options,
agreements, convertible securities or other commitments or securities
convertible into, or exchangeable or exercisable for, shares of Common Stock
(including the Series A Preferred Stock issued hereunder, collectively, "Common
Stock Equivalents") pursuant to which the Corporation is or may become
obligated to issue any shares of the capital stock or other securities of the
Corporation, which names all persons entitled of record to receive such shares
or other securities, the shares of capital stock or other securities required
to be issued thereunder as of the date hereof and the price per share, if any,
payable with respect to the issuance of any share of capital stock issuable
thereunder.  Except as set forth on Schedule 2.3(b), the Corporation has no
knowledge of the names of any beneficial owners of shares of capital stock who
are not otherwise holders of record.  Except as set forth on Schedule 2.3(b) or
as contemplated by the Documents or the Stockholders Agreement of even date
herewith among the Corporation, Waters and Sancilio and the other persons
listed on Schedule 1 thereto (the "Waters-Sancilio Agreement") there are, and
immediately after the Closing, there will be, no Common Stock Equivalents
outstanding and no rights, including preemptive or similar rights, to purchase
or otherwise acquire shares or sell or otherwise transfer shares of the capital
stock of the Corporation pursuant to any provision of law, the Certificate of
Incorporation or the By-laws, any agreement to which the Corporation is a party
or, to the best knowledge of the Corporation, otherwise; and, except as set
forth on Schedule 2.3(b) or as contemplated by the Documents, the Corporation
is not a party to, and, to the Corporation's best knowledge, there are, and
immediately after the Closing, there will be, no agreement, restriction or
encumbrance (such as a right of first refusal, right of first offer, proxy,
voting agreement, voting trust, registration rights agreement, stockholders'
agreement, etc., whether or not the Corporation is a party thereto) with
respect to the purchase, sale or voting of any shares of capital stock of the
Corporation (whether outstanding or issuable upon conversion, exchange or
exercise of outstanding securities).  Except as contemplated by the Documents
or the Waters-Sancilio Agreement or except for the right to vote its shares of
Common Stock for the election of directors, no person has the right to nominate
or elect one or more directors of the Corporation.  The shares of Common Stock
issuable upon conversion of the Series A Preferred Stock issued to the
Investors on the date of the Closing under this Agreement will represent
(following such issuance of Series A


                                       6

<PAGE>   18

Preferred Stock), in the aggregate, 20% of the outstanding Common Stock of the
Corporation on the date of the Closing and the voting power of such issued
shares will represent (following such issuance of Series A Preferred Stock), in
the aggregate, 20% of the total number of votes able to be cast on any matter
by all voting securities of the Corporation (other than any matter to be voted
on by the holders of shares of Series A Preferred Stock as a separate class) on
the date of the Closing (treating for purposes of these calculations (i) all
Common Stock Equivalents outstanding on the date hereof as having been
converted, exchanged or exercised, (ii) any shares of Common Stock or Common
Stock Equivalents issuable pursuant to any Contract (as defined in Section
2.10(a)) entered into by the Corporation prior to the date hereof, or any
preemptive right granted by the Corporation prior to the date hereof, in each
case, as having been issued on the date hereof and (iii) all shares of Common
Stock issuable under the Corporation's 1995 Restricted Stock Award Plan as
having been issued on the date hereof).

         2.4      Authorization and Issuance of Capital Stock.  The
authorization, issuance, sale and delivery of the Series A Preferred Stock
pursuant to this Agreement and the authorization, reservation, issuance, sale
and delivery of the Conversion Shares (as defined in Section 2.5) have been
duly authorized by all requisite corporate action on the part of the
Corporation, and when issued, sold and delivered in accordance with this
Agreement, the Series A Preferred Stock and the Conversion Shares will be
validly issued and outstanding, fully paid and nonassessable with no personal
liability attaching to the ownership thereof, free of any Encumbrances (as
defined in Section 2.15(a)), other than Encumbrances, if any, arising as a
result of actions taken by the Investors, and not subject to preemptive or
similar rights of the stockholders of the Corporation or others.  The terms,
designations, powers, preferences and relative, participating, optional and
other special rights, and the qualifications, limitations and restrictions, of
any series of Preferred Stock of the Corporation are as stated in the
Certificate of Incorporation and the By-Laws.

         2.5      Reservation of Shares.  The Corporation has reserved a

<PAGE>   29
or "associate" (as such terms are defined in Rule 12b-2 under the Securities
Exchange Act of 1934, as amended (the "Exchange Act")) of any of the foregoing
persons or any AAI Entity is presently, or during the past five years has been
or, in the case of any agreement or transaction with respect to which any AAI
Entity currently has any liability (contingent or otherwise) in excess of
$10,000, since the organization of such AAI Entity has been, directly or
indirectly, a party to any agreement, transaction or series of similar
transactions with any AAI Entity pursuant to which payments in excess of
$10,000 are to be or have been made or liabilities in excess of $10,000
currently exist, other than in connection with any such person's duties as a
director, officer or employee of such AAI Entity.

         (b)      Each ongoing intercompany transaction set forth on Schedule
2.21(a) is on terms that are (i) consistent with the past practice of the AAI
Entity party thereto and (ii) at least as favorable to the such AAI Entity as
would be available with independent third parties dealing at arms' length.

         2.22     Disclosure.  (a)  This Agreement and all certificates,
instruments or written statements furnished or made to the Investors by or on
behalf of the Corporation in connection with this Agreement, taken as a whole,
and including any corrective materials furnished or made available to Investors
prior to the date hereof, do not contain any untrue statement of a material
fact or omits to state a material fact necessary in order to make the
statements contained herein and therein not misleading; provided, however, that
to the extent any such certificate, instrument or written statement has been
prepared by a third party, to the best knowledge of the Corporation, such
certificate, instrument or written statement does not contain any untrue
statement or a material fact or omit to state a material fact necessary to make
the statements contained therein not misleading.  In addition, the
representations and warranties set forth in this Section 2.22(a) are subject to
the following qualifications:  (i) any projections furnished or made available
to the Investors by or on behalf of the Corporation are based on assumptions
that, to the best knowledge of the Corporation, were reasonable as of the date
of preparation of such projections and include assumptions concerning certain
facts and events over which the Corporation does not have control; (ii) any
change in one or more of the assumptions used in such projections could have a
material adverse effect on the projected financial results of the Corporation
or any entity for which such projections were prepared; (iii) there can be no
assurance that such projections will be realized; and (iv) to the extent any
such written statement presents or is based on an anticipated timetable for
obtaining FDA approvals of any products developed or proposed to be developed
by any AAI Entity or any other person, the Corporation advised each Investor,
and each Investor acknowledges, that the time requirements for completing the
development and regulatory processes for FDA approval of any application are
not subject to precise determination and there can be no assurance that any
pharmaceutical products will be approved in any


                                       18

<PAGE>   30

estimated time, if at all.  Except as expressly set forth in Section 2.34(e),
the parties acknowledge that the limitations contained in (i) the proviso to
the first sentence and (ii) the second sentence of this Section 2.22(a), in
each case, relate solely to the representations and warranties made by the
Corporation in the first sentence of this Section 2.22 and do not modify any
other representation and warranty of the Corporation.  The assumptions upon
which the projections dated September 1995 which were provided to the Investors
were based have not changed in any material respect.

         (b)      There is no fact peculiar to the AAI Entities or their
business which the Corporation has not disclosed to the Investors or their
counsel and of which the Corporation is aware which materially and adversely
affects or which, so far as the Corporation can now reasonably foresee, will
materially and adversely affect its business, financial condition, operations,
property or affairs or the ability of any AAI Entity to perform its obligations
under the Documents.

         2.23     Taxes.  (a)  Except as set forth on Schedule 2.23(a), each of
the AAI Entities has filed all Tax Returns (as such terms are defined below)
required by law to have been filed by it and has paid all Taxes required to be
paid by it including, without limitation, any Tax levied upon any of its
properties, assets, income or franchises.  All Tax Returns filed by the AAI
Entities were complete and correct in all material respects and, except as set
forth in Schedule 2.23(a), each such Tax Return was timely filed.  All amounts
required to be collected or withheld by each of the AAI Entities, have been
collected or withheld and any such amounts that are required to be remitted to
any taxing authority have been duly remitted.  The accruals and reserves for
Taxes in each of the balance sheets referenced in Section 2.6 are adequate in
all material respects to cover any liability of the Corporation for Taxes for
periods through the dates of such balance sheets.  The accruals and reserves
for deferred tax liability in each of the balance sheets referenced in Section
2.6 are adequate to cover any such liability in accordance with GAAP.  If each
of the AAI Entities files its respective Tax Returns for its taxable year,
which includes the date hereof in conformance with its past practices and tax
reporting, to the best knowledge of the Corporation, there will be no basis for
any material adverse audit adjustments with respect to any of the AAI Entities
under any of the provisions of the Code, or any provisions of state, local or
foreign tax law, with respect to operations and activities of any of the AAI
Entities during the period which began on January 1, 1995 and ends on the date
hereof.  "Taxes," for purposes of this Agreement, means any taxes, assessments,
duties, fees, levies, imposts, deductions, withholdings, including, without
limitation, income, gross receipts, ad valorem, value added, excise, real or
personal property, asset, sales, use, license, payroll, transaction, capital,
net worth and franchise taxes, estimated taxes, withholding, employment, social
security, workers compensation, utility, severance, production, unemployment
compensation, occupation, premium, windfall profits, transfer and gains taxes,
or other governmental charges of any


                                       19

<PAGE>   31

nature whatsoever imposed by any government or taxing authority of any country
or political subdivision of any country and any liabilities with respect
thereto, including any penalties, additions to tax, fines or interest thereon,
and includes any liability of any of the AAI Entities arising under any tax
sharing agreement to which any of them is or has been a party.  For purposes of
this Agreement, "Return" shall mean any report, return, statement, estimate,
declaration, notice, form or other information required to be supplied to a
taxing authority in connection with Taxes.  For purposes of this Section 2.23,
the term "AAI Entity" shall include any corporation or similar entity to which
such entity is a successor by merger, liquidation or otherwise.

         (b)      For federal income tax purposes, the Corporation is and has
been properly classified as an "S Corporation" under Section 1361(a) of the
Code and the Treasury Regulations promulgated thereunder (and any applicable
predecessor provisions) for all periods ended on or after January 1, 1988 and
has been so classified for state and local purposes pursuant to analogous state
and local provisions for the periods and in the jurisdictions listed on
Schedule 2.23(b).

         (c)      No taxing authority in a jurisdiction where any of the AAI
Entities do not file Tax Returns has made a claim, assertion or threat that
such non-filing entity is or may be subject to taxation by such jurisdiction.
Schedule 2.23(c) contains a list of states, territories and jurisdictions
(whether foreign or domestic) in which each of the AAI Entities has filed an
income, franchise, sales and use tax return for taxable periods ending on or
after December 31, 1990.  All taxable years of each of the AAI Entities for
federal, state and foreign local income tax purposes for periods ended on or
before December 31, 1987 have been closed by expiration of the applicable
statute of limitations (taking into account waivers and extensions).

         2.24     Environmental Protection.  Except as set forth in Schedule
2.24(a), each AAI Entity at all times has in all material respects been
operated, and in all material respects is, in compliance with all applicable
federal, state, local, and foreign laws, rules, regulations, codes, ordinances,
orders, decrees, directives and judgments relating to Environmental Matters (as
defined below), including all limitations, restrictions, conditions, standards,
prohibitions, requirements, obligations, schedules and timetables contained in
all applicable Environmental Laws (as defined below), except to the extent that
the failure to so comply would not individually or in the aggregate have a
Material Adverse Effect.  Except as set forth in Schedule 2.24(b), each AAI
Entity has obtained, and is in material compliance with, all material permits,
licenses, authorizations, registrations and other governmental consents
required by applicable Environmental Laws ("Environmental Permits"), including,
without limitation, those regulating emissions, discharges, or releases of
Hazardous Substances (as defined below), or the use, storage, treatment,
transportation, release, emission and disposal of raw materials, by-products,


                                       20

wastes and other substances used or produced by or otherwise relating to its
business.  Except as set forth in Schedule 2.24(c), there are no claims,
notices, civil, criminal or administrative actions, suits, hearings,
investigations, inquiries or proceedings pending or, to the best knowledge of
the Corporation, threatened against the Corporation that are based on or
related to any Environmental Matters or the failure to have any required
Environmental Permits.  Except as set forth in Schedule 2.24(d), there are no
past or present conditions, events or circumstances (i) that may interfere with
or prevent continued compliance by any AAI Entity with Environmental Laws and
the requirements of Environmental Permits, (ii) that may give rise to any
liability or other obligation under any Environmental Laws that may require any
AAI Entity to incur any actual or potential Environmental Costs, or (iii) that
may form the basis of any claim, action, suit, proceeding, hearing,
investigation or inquiry against or involving any AAI Entity based on or
related to any Environmental Matter or which could require any AAI Entity to
incur any Environmental Costs.  Except as set forth in Schedule 2.24(e), there
are no underground or aboveground storage tanks, incinerators or surface
impoundments at, on, or about, under or within any real property or tangible
assets owned, operated or controlled in whole or in part by any AAI Entity.
Schedule 2.24(e) also lists all underground or aboveground storage tanks,
incinerators or surface impoundments that were removed from any such
properties.  Except as set forth in Schedule 2.24(f), no AAI Entity has
received any written notice or other communication that it is or may be a
potentially responsible person or otherwise liable in connection with any waste
disposal site allegedly containing any Hazardous Substances, or other location
used for the disposal of any Hazardous Substances, or notice of any failure on
its behalf to comply in any material respect with any Environmental Law or the
requirements of any Environmental Permit.  Except as set forth on Schedule
2.24(g), no AAI Entity has used any waste disposal site, or otherwise disposed
of, transported, or arranged for the transportation of, any Hazardous
Substances to any place or location, or in violation of any Environmental Laws.
Except as set forth in Schedule 2.24(h), no lien exists, and no condition
exists which could result in the filing of a lien, against any property of any
AAI Entity under any Environmental Law or relating to any Environmental Matter.
Except as set forth in Schedule 2.24(i), there has been no release or other
dissemination at any time of any Hazardous Substances at, on, or about, under
or within any real property currently or formerly owned or leased by any AAI
Entity or any predecessor of any AAI Entity or any real properties operated or
controlled by any AAI Entity (other than pursuant to and in accordance with
permits held by any AAI Entity or its predecessor).  Except as set forth in
Schedule 2.24(j), no AAI Entity has been requested or required by any
governmental authority to perform any investigatory or remedial activity or
other action in connection with any Environmental Matter.  Notwithstanding any
other provision set forth herein, and subject to the following qualifications,
each of the representations and warranties set forth in this Section 2.24 is
made to the best knowledge of the Corporation, except that the representations
and warranties set forth in this Section


                                       21

its own account, for investment and not with a view to the distribution thereof

to cause the rent payable by the Corporation for the space leased by the
Corporation at 5051 New Centre Drive (the "Building") to, at all times, reflect
a reasonable fair market rent payable by a creditworthy entity for comparable
space in a property which is similar in character to the Building.

                  4.8.3.  Sancilio Payment.  The Sancilio Payment represents

as of the date hereof under Section 5.2 of the employment agreement with
Sancilio which is being terminated on the date hereof pursuant to Section
1.3(i) minus (ii) $22,500 (the "Credit").  In consideration of the Credit
(which is intended in lieu of any bonus payment payable to Sancilio for the
period from November 1, 1995 to December 31, 1995), Sancilio agrees that the
Corporation will not have to pay, and Sancilio waives the right to receive, any


                                       32

<PAGE>   44

further bonus payment from the Corporation with respect to the fiscal year
ending December 31, 1995.

         4.9      Disclosure of Investment.  Each of the Corporation, on the
one hand, and each of the Investors, on the other hand, agrees that it will
not, (i) except as may be necessary or desirable in connection with a request
by a governmental agency, regulatory or supervisory authority or court or as
required by law and other than to potential investors in the Corporation or to
the equity participants in any Investor, disclose the transactions contemplated
by the Documents or any of the terms thereof without the prior consent of the
other party, (ii) use in advertising or publicity the name of any party hereto,
or any partner or employee of such party hereto or any of its respective
affiliates, or any trade name, trademark, trade device, service mark, symbol or
any abbreviation, contraction or simulation thereof owned by the other party
hereto or any of its respective affiliates, in either case without the prior
written consent of such party or (iii) represent, directly or indirectly, any
product or any service provided by the Corporation has been approved or
endorsed by any Investor without the prior written consent of the Investor;

to any lending institution in connection with any financing), and the Investors
may disclose the following:  (i) that the Investors are stockholders of the
Corporation, (ii) the aggregate purchase price paid by each Investor in
connection with the investment contemplated by this Agreement and (iii) the
percentage of the outstanding shares of capital stock of the Corporation held
by each Investor.

         4.10     Use of Proceeds.  The Corporation shall use the proceeds from
the sale of Series A Preferred Stock hereunder as set forth on Schedule 4.10.

         4.11     Investment Banking Services.  Goldman, Sachs & Co. ("Goldman
Sachs") or any affiliate of Goldman Sachs shall have the right to perform all
investment banking services for the Corporation for which an investment banking
firm is retained (including, without limitation, with respect to the sale of
the Corporation) and Goldman Sachs shall have the right to act as the lead
managing underwriter with request to any public offering of securities of the
Corporation or any secondary offering of the securities of the Corporation, in
each case, upon customary terms, including compensation, consistent with an
arm's-length transaction.  If the Corporation engages Goldman Sachs or any of
its affiliates to be a managing underwriter in connection with any underwriting
of its capital stock and the Corporation desires to engage one or more
investment bankers as co-managing underwriter(s) in connection with such
offerings, the Corporation shall have the right to select such co-managing
underwriter(s).  If the Corporation and Goldman Sachs or its affiliate, after
good faith discussions, cannot agree on the terms of any such engagement, the
Corporation may hire such other investment banker as they find acceptable
provided that Goldman Sachs will then be entitled to be a co-managing


                                       33

<PAGE>   45


underwriter in connection with any such underwriting of capital stock of the
Corporation.  The rights of the GSCP Parties and the obligations of the
Corporation to the GSCP Parties under this Section 4.11 shall terminate at such
time as the GSCP Parties, together with their affiliates, in the aggregate, own
less than 5% of the outstanding Common Stock of the Corporation (treating for
purposes of these calculations all shares of Series A Preferred Stock and all
Common Stock Equivalents as having been converted, exchanged or exercised).

         4.12     Share Issuance.  The Corporation shall not issue, sell or
grant any capital stock or other equity securities or Common Stock Equivalents
unless as a condition to such issuance, sale or grant the purchaser or grantee
executes and agrees to be bound the Stockholder Agreement.

SECTION 5.        Transfer Taxes.  The Corporation agrees that it will pay, and
will hold each Investor harmless from any and all liability with respect to any
stamp or similar Taxes which may be determined to be payable in connection with
the execution and delivery and performance of this Agreement, and that it will
similarly pay and hold each Investor harmless from all Taxes in respect of the
issuance of the Series A Preferred Stock and the Conversion Shares to such
Investor.

SECTION 6.        Survival of Representations, Warranties, Agreements and
Covenants, etc.  All representations and warranties in the Documents shall
survive the Closing until the earlier of (i) the third anniversary of the date
hereof and (ii) the consummation of a Qualified IPO (as defined below) (except
to the extent a Claim Notice (as defined in Section 8.4) shall have been given
prior to such date with respect to a breach of a representation and warranty,
in which case such representation and warranty shall survive until such claim
is resolved) and shall in no way be affected by any investigation or knowledge
of the subject matter thereof made by or on behalf of any Investor; provided,
however, the representations and warranties set forth in Sections 2.1, 2.2,
2.3, 2.4, 2.5, 2.7 (to the extent related to Taxes) and 2.23 shall survive the
Closing indefinitely.  All statements contained in any certificate or other
instrument delivered by the Corporation pursuant to this Agreement shall
constitute representations and warranties by the Corporation under this
Agreement.  All agreements contained herein shall survive indefinitely until,
by their respective terms, they are no longer operative; provided, however,
that the rights of an Investor and the obligations of the Corporation to such
Investor under Section 4 of this Agreement shall, unless otherwise specified
therein, terminate upon the consummation of a Qualified IPO (as defined below).
"Qualified IPO" shall mean a bona fide, firm commitment, underwritten public
offering of Common Stock pursuant to an effective registration statement under
the Securities Act, (i) resulting in at least $20,000,000 of net proceeds to
the Corporation and any selling stockholders after deducting underwriting
discounts and commissions and offering expenses, and


                                       34

<PAGE>   46


(ii) reflecting a net per share offering price (after deducting underwriting
discounts and commissions and offering expenses) of at least (A) $1,055.634
(the "Conversion Price"), from and after the time GSCP Parties (I) transfer any
of their Series A Preferred Stock to any person other than a GSCP Affiliate or
(II) exercise any of their demand registration rights under the Registration
Rights Agreement, and (B) otherwise, (I) $1,319.543, which represents 125% of
the Conversion Price, if the offering is consummated by November 17, 1996 or
(II) $1,583.451, which represents 150% of the Conversion Price, if the offering
is consummated after November 17, 1996.

SECTION 7.        Expenses.  (a)  Except as set forth in Section 7(b), the
Corporation and each Investor shall pay all the costs and expenses incurred by
it or on its behalf in connection with this Agreement and the consummation of
the transactions contemplated hereby.

         (b)      The Corporation shall pay and shall reimburse the GSCP
Parties at the Closing for their reasonable fees and expenses incurred after
July 1, 1995 in connection with this transaction including, without limitation,
the fees and expenses of counsel retained by the GSCP Parties in connection
with the negotiation and preparation of the Documents and the documentation
relating thereto and the consummation of the transactions contemplated
hereunder; provided, however, in no event shall the liability of the
Corporation under Section 7(b) in the aggregate exceed $125,000.

SECTION 8.        Indemnification.

         8.1      General Indemnification.  The Corporation shall indemnify,
defend and hold each Investor (other than Waters), its affiliates, their
respective officers, directors, employees, agents, representatives, successors
and assigns (each an "Investor Entity") harmless from and against all Losses
(as defined below) incurred or suffered by an Investor Entity (whether incurred
or suffered directly or indirectly through ownership of Common Stock or
Preferred Stock) arising from the breach of any of the representations,
warranties, covenants or agreements made by it in this Agreement or in any
certificate or other instrument delivered pursuant hereto including, without
limitation, the Documents.  Each Investor, severally and not jointly, shall
indemnify, defend and hold the Corporation, its affiliates, their respective
officers, directors, employees, agents, representatives, successors and assigns
harmless against all Losses arising from the breach of any of its
representations, warranties, covenants or agreements in this Agreement or in
any certificate or other instrument delivered pursuant hereto, including,
without limitation, the Documents.  Notwithstanding anything to the contrary in
this Agreement, (i) any event, fact, matter or circumstance which, but for this
subclause (i), would constitute a breach of any representation and warranty of
any AAI Entity contained in this Agreement (any such event, fact, matter or
circumstance, a "Section 8 Event") shall not


                                       35

<PAGE>   47


be treated as a breach of such representation and warranty (other than Section
8 Events relating to the representations and warranties contained in Sections
2.7, 2.8(c), 2.8(h), 2.8(l), 2.10(a), 2.12(a), 2.16(a), 2.21, 2.28, 2.35, the
last sentence of 2.3(b) and the first sentence of Section 2.17, with respect to
which representations and warranties the Threshold (as defined below) shall not
be applicable to determine whether a breach of such representation and warranty
has occurred) until the Losses to the Corporation arising or resulting from
such Section 8 Event (or in the case of a series of related Section 8 Events
which are based on similar facts or circumstances, arising or resulting from
all such related Section 8 Events) exceed $50,000 (the "Threshold") in which
event the entire amount of the Losses arising from such Section 8 Event(s)
shall be deemed Losses subject to indemnification under this Section 8 (subject
to application of the Deductible), and (ii)  no indemnification payment by the
Corporation pursuant to this Section 8 with respect to any Losses otherwise
payable hereunder as a result of a breach of its representations and warranties
(other than any Losses resulting from breaches of the representations and
warranties in Sections 2.21(a), 2.23(b) and 2.35 which shall not be subject to
the Deductible (as defined below)) shall be payable until the time as such
Losses shall aggregate for all Investor Entities to more than $200,000 (the
"Deductible"), and then only to the extent that such Losses, in the aggregate
for all Investor Entities, exceed the Deductible.

         8.2      Tax and Litigation Indemnification.  Waters and Sancilio
shall jointly and severally indemnify, defend and hold the Corporation harmless
from and against all Losses (including, without limitation, any interest or
penalties) incurred by the Corporation arising from (i) the imposition of any
Income Taxes on the Corporation for any period ending prior to the date hereof
as a result of any failure to make a proper and valid election under Section
1361(a) of the Code and the Treasury Regulations promulgated thereunder, other
than Income Taxes imposed by Illinois, Massachusetts and New Jersey, (ii) final
resolution of the Corporation's liability in respect of the judgment of
approximately $350,000 entered into against the Corporation with respect to a
litigation by Lewis Kurtzman against the Corporation, and (iii) final
resolution of the assessment by the North Carolina Department of Revenue for a
deficiency with respect to use tax in the amount of approximately $340,680.
GSCP is intended to be a third party beneficiary of the terms of this Section
8.2 and may enforce the Company's rights hereunder.

         8.3      Indemnification Principles.  For purposes of this Section 8,
(i) "Losses" shall mean each and all of the following items:  claims, losses,
(including, without limitation, losses of earnings) liabilities, obligations,
payments, damages (actual, punitive or consequential), charges, judgments,
fines, penalties, amounts paid in settlement, costs and expenses (including,
without limitation, interest which may be imposed in connection therewith,
costs and expenses of investigation, actions, suits, proceedings, demands,
assessments and fees, expenses and disbursements of counsel, consultants and
other


                                       36

<PAGE>   48


experts); provided, however, that any Loss to the Corporation of future
earnings arising from any representation and warranty contained in this
Agreement not being true and correct when made shall be computed based on the
present value (discounted at a rate of 10%) of the otherwise expected earnings
stream to the Corporation had such representation and warranty been true and
correct when made; provided, further, that the preceding proviso will not be a
limitation in determining the amount of any Loss to the Corporation or the
Investors (including by reason of any Loss to the Corporation of future
earnings) arising from any breach of the representation and warranty contained
in Section 2.6 of this Agreement and (ii) each of the representations and
warranties made by any party in this Agreement or in any certificate or other
instrument delivered pursuant hereto (other than the representation and
warranty made in subclause (a) of Section 2.8 and in Section 2.22(b)),
including, without limitation, the Documents, shall be deemed to have been made
without the inclusion of limitations or qualifications as to materiality, such
as the words "material adverse affect," "immaterial," "material" and "in all
material respects" or words of similar import.  Any indemnification payment by
the Corporation to an Investor pursuant to this Section 8 shall include an
additional amount so that such Investor suffers no Loss as a result of any
diminution in the book value of the stockholder's equity related to its
investment under the Agreement as a result of such indemnification payment.
Any payment by the Corporation to an Investor pursuant to this Section 8, shall
be treated for federal income tax purposes as an adjustment to the price paid
by such Investor for the Series A Preferred Stock pursuant to this Agreement.

         8.4      Claim Notice.  No party shall be entitled to indemnification
against a Loss arising from the breach of any representations or warranties of
any other party unless the party seeking indemnification shall have given to
the party from whom indemnification is being sought a claim notice relating to
such Loss (a "Claim Notice") prior to expiration of the representation or
warranty upon which the claim is based.  The Claim Notice shall be given
reasonably promptly after the party seeking indemnity becomes aware of the
facts indicating that a claim for indemnification may be warranted.  Each Claim
Notice shall specify the nature of the claim, the applicable provision(s) of
this Agreement or other instrument under which the claim for indemnity arises,
and, if possible, the amount or the estimated amount thereof.  No failure or
delay in giving a Claim Notice (so long as the same is given prior to
expiration of the representation or warranty upon which the claim is based) and
no failure to include any specific information relating to the claim (such as

        Borrower has kept, observed, performed and fulfilled each and every
        agreement binding on it contained in this Loan Agreement and the Loan
        Documents and is not at the time in default in the keeping, observance,
        performance or fulfillment of any of the terms, provisions and
        conditions of this Loan Agreement or any of the Loan Documents and that
        no Event of Default specified in Article XII hereof, nor any event,
        which, upon notice or lapse of time or both, would constitute such an
        Event of Default, has occurred, or if such Event of Default exists or
        would occur as the case may be, stating the nature thereof, the period
        of existence thereof and what action the Borrower proposes to take with
        respect thereto;

               (e)     promptly, from time to time, deliver to the Bank such

               (g)     do or cause to be done all things necessary to preserve

        franchises;

               (h)(i) comply with or contest in good faith all statutes and
        governmental regulations of which the Borrower has knowledge and the

        financial condition of the Borrower; and (ii) pay all taxes,
        assessments, governmental charges, claims for labor, supplies, rent and
        any other obligation which, if unpaid, might become a lien against any
        of its properties except liabilities being contested in good faith and
        against which, if reasonably requested by the Bank, reserves
        satisfactory to the Bank will be established;

               (i)     at all times keep its insurable properties insured to

        replacements, betterments and improvements thereto;

               (k)     keep true books of records and accounts in accordance
        with Generally Accepted Accounting Principles applied on a Consistent

        records at such times as the Bank may reasonably request upon
        reasonable notice and during ordinary business hours;

               (m)     upon the request of the Bank, authorize any officer of

        business hours;

               (n)     deliver to the Bank forthwith, upon any officer of the
        Borrower obtaining knowledge of an Event of Default or an event which

        chief executive officer of the Borrower specifying the nature and
        period of existence thereof and what action the Borrower proposes to
        take with respect thereto;

        officer of the Borrower, notify the Bank in writing of the occurrence
        of any of the following events:

               becomes aware of such lien;

               (e)     if an event of default occurs under any agreement by and

        hereof (including the Reimbursement Agreement dated as of November 1,

               (f)     if the Borrower in the performance of any other
        agreement between it and any other lender defaults and such default
        permits such other lender to accelerate such other indebtedness of the
        Borrower for borrowed money;

               (g)     the Guarantors shall at any time cease or fail to own in
        the aggregate 51% or more of the voting stock of the Borrower; or

               (h)     either Guarantor shall default in the performance of any
        obligation under the Guaranty Agreement.

        12.2   Remedies.  Upon the occurrence of any such Event of Default and
after the applicable grace period, if any, and unless the Bank agrees to waive
in writing such an Event of Default:

               (a)     Termination of Commitment.  The Bank, in its sole
        discretion, may terminate the Commitment.

               (b)     Acceleration of Indebtedness.  All of the indebtedness
        of any and every kind owing by the Borrower to the Bank, howsoever
        evidenced, now existing or hereafter arising, shall become due and
        payable upon written notice to the Borrower (other than an Event of
        Default described in Section 12.1(d) in which case such indebtedness
        shall become due and payable immediately without necessity of written
        demand) without the necessity of any other demand, presentment, protest
        or notice upon the Borrower, all of which are hereby expressly waived
        by the Borrower.

               (c)     Acceleration of Obligations.  All of the obligations of
        the Borrower under the Loan Documents shall thereupon be immediately
        due and payable without the necessity of any other demand, presentment,
        protest or notice upon the Borrower, all of which are hereby expressly
        waived by the Borrower.

               (d)     Right of Set-Off.  Regardless of the adequacy of the
        collateral, the Bank shall have the right, immediately and without
        further action by it, to set-off against the Notes, all money owed by
        the Bank in any capacity to the Borrower, whether or not due, and the
        Bank shall be deemed to have exercised such right of set-off and to
        have made a charge against any such money immediately upon the
        occurrence of such event of default even though such charge is made or
        entered on the books of the Bank subsequent thereto.

               (e)     Foreclosure.  The Bank may cause foreclosure upon any
        collateral as authorized in the Loan Documents in order to satisfy all
        obligations of the Borrower to the Bank under and pursuant to all of
        the rights and powers and in the manner contained in the Loan
        Documents.  The Borrower hereby agrees that the Bank shall have the
        right to bid and become a purchaser on its own behalf in any such
        sales.

         dividends declared or paid or redemptions of stock or other
         distributions of cash or property to shareholders of the Borrower;

                 (d)      Section 2.01 is amended in its entirety so that such

         the Bank agrees to make Revolving Loans to the Borrower, at any time
         or from time to time on or after the date hereof and until the
         Revolving Loan Maturity Date, in an aggregate principal amount at any

         unused fee of one-quarter of one percent (1/4%) per annum (computed on
         the basis of the actual number of days elapsed in a year of 360 days)
         on the average daily Unutilized Commitment during the preceding period
         (for purposes hereof, the term "Unutilized Commitment" shall mean, at

         (a)     Use of Proceeds; Prohibited Uses of Project, etc.  Neither the
Issuer nor the Company shall cause any proceeds of the Bonds to be expended
except pursuant to the Indenture.  The Company shall not (1) requisition or
otherwise allow any payment out of proceeds of the Bonds (A) if such payment is
to be used for the acquisition of any property (or an interest therein) unless
the first use of such property is pursuant to such acquisition, provided that
this clause (A) shall not apply to any building (and the equipment purchased as
a part thereof, if any,) if the "rehabilitation expenditures", as defined in
Section 147(d) of the Code, with respect to the building equal or exceed 15% of
the portion of the cost of acquiring the building (including such equipment)
financed with the proceeds of the Bonds, (B) if as a result of such payment,
25% or more of the proceeds of the Bonds would be considered as having been
used directly or indirectly for the acquisition of land (or an interest
therein); (C) if, as a result of such payment, less than 95% of the net
proceeds of the Bonds, expended at the time of such requisition would be
considered as having been used for costs of the acquisition, construction, or
reconstruction or improvement of land or property of a character subject to the
allowance for depreciation within the meaning of Section 144(a)(1)(A) of the
Code ("Qualifying Costs") or (D) if such payment is used to pay issuance costs
(including counsel fees, remarketing fees and placement fees) of the Bonds in
excess of an amount equal to 2% of the principal amount of the Bonds; (2) take
or omit, or permit to be taken or omitted, any other action with respect to the
use of such proceeds the taking or omission of which would result in the loss
of exemption of interest on the Bonds from Federal income taxation under
Section 144 of the Code; or (3) take or omit, or permit to be taken or omitted,
any other action the taking or omission of which would cause the loss of such
exemption.  Without limiting the generality of the foregoing, the Issuer and
the Company shall not use the proceeds of the Bonds, or permit such proceeds to
be used directly or indirectly, for the acquisition of land (or an interest
therein) to be used for farming purposes, or to provide (x) any facility the
primary purpose of which is retail food and beverage services, automobile sales
or service or the provision of recreation or entertainment, (y) any airplane,
skybox or other private luxury box, any health club facility, any facility
primarily used for gambling, any store the principal business of which is the
sale of alcoholic beverages for consumption off premises, any private or
commercial golf course, country club, massage parlor, tennis club, skating
facility (including roller





                                      -16-
<PAGE>   21

skating, skateboard and ice skating), racquet sports facility (including any
hand ball or racquet ball court), hot tub facility, suntan facility, or race
track, or (z) single or multi-family residences.  The Company shall not permit
the use of the Project by any person to whom any part of the aggregate
authorized face amount of the Bond would be allocated pursuant to Section
144(a)(10) of the Code if the amount so allocated when increased as provided in
Section 144(a)(10) of the Code would exceed $40,000,000.

         (b)     Commencement of Construction; First Users.  The Company hereby
represents that neither "construction" nor "acquisition" of the Project
"commenced" prior to January 21, 1988, within the meaning of Section 144 of the
Code.  No person, firm or corporation who was a substantial user" of the
Project (within the meaning described in such term under Section 144(a) of the
Code) before the date of issuance of the Bonds and who was or will be a
"substantial user" of the Project following its being placed in service, has
received or will receive, directly or indirectly, any proceeds from the
issuance and sale of the Bonds, except for the Company.  The project was not
"first used," within the meaning of Section 144(a) of the Code and the Treasury
Regulations promulgated thereunder, prior to the date one year prior to the
issuance of the Bonds.

         (c)     Economic Life of Project.  The Company hereby represents that
the "average reasonably expected economic life" of the components comprising
the Project, determined pursuant to Section 147(b) of the Code, is not less
than the amount set forth in the certificates or letters of representation of
the Company delivered at the issuance of the Bonds.  The weighted average
maturity of the Bonds does not exceed 120% of the "average reasonably expected
economic life" of the components comprising the Project, determined pursuant to
Section 147(b) of the Code, as set forth in the certificates or letters of
representation of the Company delivered at the issuance of the Bonds.  The
Company agrees that it will not make any changes in the Project which would, at
the time made, cause 120% of the "average reasonably expected economic life" of
the components of the Project, determined pursuant to Section 147(b) of the
Code, to be less than the "average maturity of the bonds" set forth in the
certificates or letters of representation of the company delivered at the
issuance of the Bonds.

         (d)     Certificate of Information; Internal Revenue Service Form
8038.  The Company hereby represents that the information contained in the
certificates or letters of representation of the Company with respect to the
compliance with the requirements of Sections 103 and 144 and Sections 146
through 149 of the Code, including the information in Internal Revenue Service
Form 8038 (excluding the issue number and the  employer identification of the
Issuer) filed by the Issuer with respect to the Bonds and the Project, is true
and correct in all material respects.





                                      -17-
<PAGE>   22

         (e)     Arbitrage and Rebate.  Neither the Company nor the Issuer
shall (1) take or omit to take any action, or approve the Company's making any
investment or use of any proceeds of the Bonds or any other moneys within their
respective control (including without limitation the proceeds of any insurance
or any condemnation award with respect to the Project) or the taking or
omission of any other action, which would cause the Bonds to be "arbitrage
bonds" within the meaning of the Section 148 of the Code, or (2) approve the
use of any proceeds from the sale of the Bonds otherwise than in accordance
with the Issuer's "non-arbitrage" certificate given at the issuance of the
Bonds barring any unforeseen circumstances, in which event the Company and the
Issuer shall use such proceeds with due diligence and shall otherwise comply
with the "nonarbitrage" certificate.  Without limiting the generality of the
foregoing, the Company shall at its sole expense take all action required under
Section 148 of the Code and Treasury Regulations thereunder to prevent loss of
the exclusion from gross income for purposes of Federal income taxation of
interest on the Bonds under such Section, including but not limited to paying
on behalf of the Issuer the "rebate amount" to the United States of America in
accordance with the "rebate requirement" described in Section 1.103-15AT9(d)(1)
of such Treasury Regulations, and complying with the requirements of Section
510 of the Indenture.  The Company shall also comply with any similar
requirements contained in any final Treasury Regulations adopted in place of
Section 1.103-15AT of such Treasury Regulations and all other requirements of
any such final Treasury Regulations.

         (f)     Use by United States of America or its Agencies.  The Company
shall not permit the Project to be used or occupied other than as a member of
the general public in any manner for compensation by the United States of
America or an agency or instrumentality thereof, including any entity with
statutory authority to borrow from the United States of America (in any case
within the meaning of Section 149(b) of the Code) unless the Company shall
deliver to the Trustee an opinion of counsel recognized on the subject of
municipal bonds in form and substance satisfactory to the Trustee to the effect
that such use will not impair the exemption of interest on the Bonds from
Federal income taxation.

         (g)     Other Bonds to be Issued.  During the period commencing on the
date of the issuance of the Bonds and ending 30 days thereafter, there shall be
issued no "private activity bonds", as defined in Section 141 of the Code,
which are guaranteed or otherwise secured by payments to be made by the Company
or any "related person" (or group of "related persons") unless the Company
shall deliver to the Trustee an opinion of counsel recognized on the subject of
municipal bonds in form and substance satisfactory to the Trustee to the effect
that the issuance of such "private activity bonds" will not impair the
exclusion from gross income of interest on the Bonds for purposes of Federal
income taxation.





                                      -18-

Except for the Company or any "related person" (or group of "related persons"),
no person has (1) guaranteed, arranged, participated in, assisted with or paid
any portion of the cost of the issuance of, the Bonds, and (2) provided any
property or any franchise, trademark or trade name (within the meaning of
Section 1253 of the Code) which is to be used in connection with the Project.

         (h)     Limit on Amount of Bonds, Reports.  The Company represents
that on the date of the issuance of the Bonds (1) obligations have not been
assumed, expenditures have not been made and outstanding obligations do not
exist that will cause the "aggregate face amount" of the Bonds as computed
under the provisions of Section 144(a) and related sections of the Code to
exceed $10,000,000 and (2) outstanding obligations do not exist that will cause
the "aggregate face amount" of the Bonds allocated to any "test-period
beneficiary," as defined in Section 144(a)(10) of the Code, when increased by
such obligations as provided in Section 144(a)(10) of the Code, to exceed
$40,000,000.  During the three year period beginning on the date of the
issuance of the Bonds (or, in the case of (ii) below, the date the Project is
placed in service, unless the Company provides to the Trustee an opinion of
counsel recognized on the subject of municipal bonds that such restriction is
no longer applicable), the Company shall not make any expenditure, assume any
obligation, permit the use of the Project by any person or take or permit other
action that would cause the "aggregate face amount" of the Bonds as computed
under the provisions of section 144(a) and related sections of the.Code (i) to
exceed $10,000,000 or such other maximum dollar amount then permitted by the
Code, or (ii) allocated to any "test-period beneficiary," when increased by
such obligations as provided in Section 144(a)(10) of the Code, to exceed
$40,000,000.

         The Company and the Issuer shall file any reports or statements and
take any other action as may be required from time to time with respect,to the
qualification of the Bonds as Qualified small issue bonds within the meaning of
Section 144(a) of the Code.

                 (i) Election.  The Issuer hereby elects to have the provisions
of Section 144(a)(4) of the Code apply to the Bonds.  In support of this
election, the Issuer states as follows:

will be incurred from the date hereof to the.date of the issuance of the Bonds.

         Section 7.6.  Reference to Bonds Ineffective after Bonds Paid.  Upon
Payment of the Bonds and upon payment of all obligations under this Loan
Agreement, all references in this Agreement to the Bonds and the Trustee shall

         2.03      (a) The Company agrees to reimburse the Bank on the day of
any drawing under the Letter of Credit for the actual amounts paid on such
drawings.  The Company also agrees to pay interest on each unreimbursed drawing
under the Letter of Credit at the rate per annum specified in Section 2.03(b)
hereof; provided, however, that if any drawing under the Letter of Credit shall
be reimbursed to the Bank on the date of such drawing, such drawing under the
Letter of Credit shall not bear interest.

         (b)       If any drawing under the Letter of Credit is not reimbursed
in full on the date when it is made, then the amount thereof which is not so
reimbursed shall bear interest from and including the date of the making
thereof until reimbursed in full (but excluding the date of reimbursement) on
the unpaid amount thereof from time to time outstanding at a rate per annum (on
the basis of a year of 360 days) equal to the Prime Rate plus two percent (2%).
Interest owing under this Section 2.03 shall be due and payable at such time as
the Company reimburses the Bank for any drawing under the Letter of Credit and
on demand.

         (c)       The Company's obligation under this Section 2.03 to
reimburse the Bank for each drawing under the Letter of Credit shall be
absolute and unconditional under any and all circumstances and Irrespective of
any set-off, counterclaim or defense to payment which the Company may have or
have had against the Trustee, the Bank or any other Person, including, without
limitation, any defense based on any failure of the Company to receive all or
any part of the proceeds of the sale of the Bonds with respect to which such
drawing under the Letter of Credit was made or any nonapplication or
misapplication of the proceeds of such sale or the legality, validity,
regularity or enforceability of the Letter of Credit.

         2.04      (a) As security for the payment of the obligations of the
Company hereunder, the Company hereby pledges, assigns, hypothecates, transfers
and delivers to the Bank all its right, title and interest in the Bonds which
are purchased with proceeds of a draw on the Letter of Credit so long as such
Bonds are held by





                                      -6-
<PAGE>   7

the Trustee and not remarketed (the "Pledged Bonds") and hereby grants to the
Bank a security interest in and to the Pledged Bonds, the interest thereon and
all proceeds thereof, as collateral security for the prompt and complete
payment when due of all amounts due in respect of the obligations of the
Company set forth in Section 2.03 hereof.

         (b)       If the Company shall become entitled to receive or shall
receive any principal or interest payment in respect of the Pledged Bonds, the
Company agrees to accept the same as the Bank's agent and to hold the same in
trust on behalf of the Bank and to deliver the same forthwith to the Bank.  All
sums of money so paid in respect of the Pledged Bonds which are received by the
Company and paid to the Bank shall be credited against the obligations of the
Company to the Bank.

         (c)       If the Company makes or causes to be made to the Bank a
prepayment in respect of its reimbursement obligation under Section 2.03 or
such a prepayment is made on behalf of the Company as a result of a remarketing
of Bonds, the Bank agrees to release from the lien hereof and deliver to the
Company for resale in accordance with the Indenture, as the case may be,
Pledged Bonds in a principal amount equal to the amount of the prepayment so
made or to the principal amount of Pledged Bonds so purchased.

         (d)       Without the prior written consent of the Bank (which consent
may only be given if such Pledged Bonds have previously been released from the
lien of this Agreement) the Company agrees that it will not sell, assign,
transfer, exchange, or otherwise dispose of, or grant any option with respect
to, the Pledged Bonds, nor will it create, incur or permit to exist any pledge,
lien, mortgage, hypothecation, security interest, charge, option or any other
encumbrance with respect to any of the Pledged Bonds, or any interest therein,
or any proceeds thereof, except for the (i) lien and security interest provided
for by this Agreement and (ii) the sale of the Pledged Bonds pursuant to the
Indenture.

         2.05      If at any time after the date hereof, and from time to time,
the Bank determines that the adoption or modification of any applicable law,
rule or regulation regarding taxation, the Bank's required levels of reserves,
deposits, insurance or capital (including any allocation of capital
requirements or conditions), or similar requirements, or any interpretation or
administration thereof by any governmental authority, central bank or
comparable agency charged with the interpretation, administration or compliance
of the Bank with any of such requirements, has or would have the effect of (i)
increasing the Bank's costs relating to the Letter of Credit hereunder, or (ii)
reducing the yield or rate of return of the Bank on the Letter of Credit
hereunder, to a level below that which the Bank could have achieved but for the
adoption or modification of any such requirements, the Company shall, within 15
days of any request by the Bank, pay to the Bank such additional





                                      -7-
<PAGE>   8

amounts as (in the Bank's sole judgment, after good faith and reasonable
computation) will compensate the Bank for such increase in costs or reduction
in yield or rate of return of the Bank.  No failure by the Bank to immediately
demand payment of any additional amounts payable hereunder shall constitute a
waiver of the Bank's right to demand payment hereunder shall constitute a
waiver of the Bank's right to demand payment of such amounts at any subsequent
time.  Nothing herein contained shall be construed or so operate as to require
the Company to pay any interest, fees, costs or charges greater than is
permitted by applicable law.

         2.06      The amount available under the Letter of Credit (initially
$3,685,208.33 shall be reduced and reinstated as described in the Letter of
Credit.

                             AFFIRMATIVE COVENANTS

         4.01      Until the expiration of the Letter of Credit and
reimbursement of all obligations thereunder and hereunder, the Company
covenants and agrees that it will (unless the Bank shall otherwise consent in
writing):

                   (a)    within one hundred twenty (120) days of the end of
         each fiscal year, deliver to the Bank a detailed financial report of
         the Company, each corporate Guarantor and the Company and the
         corporate Guarantors on a consolidated basis based on Generally
         Accepted Accounting Principles applied on a Consistent Basis
         containing an unqualified opinion of independent certified public
         accountants acceptable to the Bank;

                   (b)    within sixty (60) days after the end of each fiscal
         quarter of each fiscal year deliver a balance sheet and profit and

         observance, performance or fulfillment of any of the terms, provisions
         and conditions of this Agreement and in the Security Documents and
         that no Event of Default specified in Article VI hereof, nor any
         event, which, upon notice or lapse of time or both, would constitute
         such an Event of Default, has occurred, or if such Event of Default
         exists or would occur as the case may be, stating the





                                     -11-
<PAGE>   12

         nature thereof, the period of existence thereof and what action the
         Company proposes to take with respect thereto;

                   (d)    promptly, from time to time, deliver to the Bank such
         other information regarding the Company's operations, business affairs
         and financial condition as the Bank may reasonably request.  The Bank
         is hereby authorized to deliver a copy of any such financial
         information delivered hereunder to the Bank to any regulatory
         authority having jurisdiction over the Bank with appropriate
         confidential restrictions being noted on any submissions of such
         information;

                   (e)    maintain or cause to be maintained all personal
         property material to its business in good working order and condition
         and make all needed repairs, replacements and renewals as are

                   (f)    do or cause to be done all things necessary to
         preserve and keep in full force and effect its corporate existence,
         rights and franchises;

                   (g)    (i) comply with or contest in good faith all statutes
         and governmental regulations of which the Company has knowledge and
         the noncompliance of which would have a material adverse effect on the
         financial condition of the Company; and (ii) pay all taxes,
         assessments, governmental charges, claims for labor, supplies, rent
         and any other obligation which, if unpaid, might become a lien against
         any of its properties except liabilities being contested in good faith
         and against which, if reasonably requested by the Bank, reserves
         satisfactory to the Bank will be established;

                   (h)    at all times keep its insurable properties insured to
         such extent and against such risks, including, without limitation,
         public liability insurance, hazard insurance, worker's compensation
         and other insurance required by law, as is acceptable to the Bank and
         is customary with companies of comparable size in the same or similar
         business but at all times of the type and at least in the amount of
         the present coverage of the Company.  The insurance coverage of the
         Company is described in Exhibit F attached hereto.  The Company will
         deliver to the Bank certificates (or endorsements showing the Bank as
         loss payee using the standard "long form") of each insurer evidencing
         the hazard insurance coverage regarding the security granted to the
         Bank by the Company.  Each such policy of hazard insurance will
         require, and the certificates will state that no such policy will be
         terminated without at least thirty (30) days prior written notice
         having been delivered to the Bank.  Except as required under the Loan
         Agreement, insurance proceeds from property securing the indebtedness
         hereunder shall be immediately applied to reduce





                                     -12-
<PAGE>   13

         such indebtedness; provided, however, insurance proceeds of less than
         $100,000.00 may be disbursed to the Company for restoration or repair
         so long as no Event of Default shall have occurred or be continuing;

                   (i)    preserve and protect its patents, licenses
         trademarks, trademark rights, tradenames, tradename rights and
         copyrights (the patents, licenses, trademarks, trademark rights,
         tradenames, tradename rights and copyrights of the Company are
         described on Exhibit G attached hereto) and maintain all of its
         other material properties and assets used or useful in the
         conduct of its business in good repair, working order and condition
         and from time to time cause to be made all proper replacements,
         betterments and improvements thereto;

                   (j)    keep true books of records and accounts in accordance
         with Generally Accepted Accounting Principles applied on a Consistent
         Basis, and in which full, true and correct entries will be made of the
         Company's dealings and transactions;

                   (k)    permit any officer of the Bank designated by the Bank
         to visit and inspect any of the Company's properties, books and
         financial records at such times as the Bank may reasonably request
         upon reasonable notice and during ordinary business hours;

                   (l)    upon the request of the Bank, authorize any officer
         of the Bank to discuss its financial statements and financial affairs
         at any time and from time to time with the Company's independent
         certified public accountants upon reasonable notice and during
         ordinary business hours;

                   (m)    use the bank as a depository, and maintain average
         demand deposit balances (after reserves and activity charges) of
         $25,000.00 or more; provided, if the Company should fail to maintain
         such average balances for any fiscal quarter (commencing with the
         fiscal quarter ending December 31, 1988) the Company shall pay to the
         Bank for such fiscal quarter a shortfall fee (the "Shortfall Fee") not
         later than forty-five (45) days after the end of such fiscal quarter
         the amount by which such average balances are less than $25,000.00
         (the "Shortfall Amount").  The Shortfall Fee shall be computed by
         multiplying the Shortfall Amount by the average Prime Rate for such
         quarterly period.  For any fiscal quarter during which there is no
         Shortfall Amount, there shall be no Shortfall Fee;

                   (n)    deliver to the Bank forthwith, upon any officer of
         the Company obtaining knowledge of an event of default under this
         Agreement or under any of the Security Documents or an event which
         would constitute such an Event of Default but for





                                     -13-
<PAGE>   14

         the requirement that notice be given or time elapse or both, a
         certificate signed by the chief executive officer of the Company
         specifying the nature and period of existence thereof and what action
         the Company proposes to take with respect thereto;

                   (o)    within ten (10) days of the event becoming known to
         any officer of the Company, notify the Bank in writing of the
         occurrence of any of the following events:

                            (i)   the pendency or commencement of any action,
                 suit or proceeding at law or in equity under which a party or
                 parties seek an amount equal to or exceeding $50,000.00;

                           (ii)   any event or condition which shall constitute
                 an event of default under any other agreement for borrowed
                 money or any known or potential materially adverse change in
                 any other material contractual agreement;

                           (iii)   any levy of an attachment, execution or other
                 process against its assets; and

                           (iv)   any change in any existing agreement or
                 contract which may materially adversely affect any of its
                 businesses or affairs, financial or otherwise;

                   (p)    on the 1st day of each month commencing December 1,
         1989, pay to NCNB National Bank of North Carolina, in its capacity as
         Escrow Agent (the "Escrow Agent") pursuant to the terms of the Escrow
         Agreement of even date herewith by and between the Escrow Agent and
         the Company as follows:

                            (i)   $20,500.00 on the 1st day of each month

                                LEASE AGREEMENT


         THIS LEASE, made as of the 7th day of March, 1994, between
5051 New Centre Drive, L.L.C, whose address is 1206 North 23rd Street,
Wilmington, North Carolina 28405 (hereinafter referred to as "Landlord"), and
Applied Analytical Industries, Inc., whose address is 1206 North 23rd Street,
Wilmington, North Carolina (hereinafter referred to as "Tenant").


         WITNESSETH:

1.       DESCRIPTION - Landlord, in consideration of the rents agreed to be
paid and the covenants agreed to be performed as specified hereafter, hereby
leases to Tenant, and Tenant hereby rents from Landlord, the premises located
in 5051 New Centre Drive, Wilmington, North Carolina which premises are
identified by suite numbers in Exhibit A-1 covering approximately the square
feet of floor area set forth on Exhibit A-1, which said premises are
hereinafter referred to as the "demised premises," together with the right and
easement to use in common with Landlord, other Tenants, their agents, employees
and invitees, parking and other common facilities as may be furnished by
Landlord on the real property described in the attached Exhibit B, which real
property, together with the buildings and other improvements erected thereon,
is hereinafter referred to as "Landlord's premises."

2.       TERM - The term of this Lease shall commence on March 7, 1994 and
continue for five (5) full calendar years.  As used herein "lease year" shall
mean a calendar year within the term of this Lease; "partial lease year" shall
mean any portion of a calendar year.

3.       DELIVERY OF POSSESSION - Landlord shall deliver possession of the
demised premises to Tenant at the commencement of the lease.

4.       RENT - Tenant shall pay to Landlord as rent for the demised premises
during each year of the term of the Lease, the amount determined by multiplying
(i) the total square feet of the demised premises set forth on Exhibit A-1 by
(ii) Twelve and 50/100 Dollars ($12.50) per square foot.  The rent is payable
in advance, in equal monthly installments, upon the first of each and every
month throughout the term of this Lease.  The first monthly installment shall
be due on the commencement of the term of this Lease.  In the event the term of
this Lease commences other than on the first of the month, there shall also be
due at the commencement of the term, such proportion of the monthly installment
as the number of days in such fractional month bears to thirty (30) days.  Any
installment of rent due or accruing hereunder and any other sum, whether termed
rent or otherwise, and payable hereunder by Tenant to Landlord, not paid when
due, shall bear interest at the highest rate provided by law until the same be
paid, and time is of the essence of this Agreement.

5.       USE AND OCCUPANCY - During the continuation of this Lease, the demised
premises shall be used and occupied for office and incidental purposes and for
no other purposes without the written consent of Landlord.  Tenant shall not
use the demised premises for any purpose in violation of any law, municipal
ordinance, or regulation, nor shall Tenant perform any acts or carry on any
practices which may injure the demised premises or the building in which the
demised premises are located to be a nuisance, disturbance or menace to the
other tenants of said building.

6.       TAXES - Landlord shall pay all general property taxes and special
assessments imposed upon the Landlord's premises, including but not limited to
land, building and improvements.  In the event a tax is enacted as a substitute
for, or in lieu of an increase in, any portion of the general property tax,
<PAGE>   2

Landlord shall pay the property tax, assessments and such substitute tax as may
be imposed upon Landlord or Landlord's property.

         Tenant shall be responsible for and pay when due all municipal, county
and state duties, taxes, fees and charges assessed during the term of this
Lease against any leasehold interest or personal property of any kind, owned or
placed in or upon the demised premises by Tenant.

7.       UTILITIES - Landlord shall furnish the Landlord's premises, including
common areas and all demised premises except those demised premises which are
separately metered, with water, heat, air conditioning, electricity, and sewage
disposal and shall at its own cost and expense replace all burned-out
fluorescent tubes, ballasts and starters in standard lighting fixtures supplied
by Landlord.  Tenant shall replace all burned-out fluorescent tubes, light
bulbs, ballasts and starters in light fixtures especially installed for Tenant.
Landlord shall not be liable or responsible for any interruption in such
utilities or other services due to causes beyond Landlord's reasonable control
or for interruptions in connection with the making of repairs or improvements
to the demised premises or the building in which the demised premises are
located.  Electricity furnished by the Landlord shall be used only for purposes
of illumination and the operation of normal office equipment (excluding,
without limitation, computer equipment).  Landlord shall not be required to
furnish heating, ventilating or air conditioning between 7 P.M. and 7 A.M. or
on Saturdays, Sundays or holidays.

8.       JANITORIAL SERVICE - Landlord shall at its own cost and expense
provide janitorial services, ice and snow removal, to the Landlord's premises,
including common areas and all demised premises.  In the event Tenant shall
require extraordinary janitorial services, the Tenant shall pay the Landlord
therefor at a rate to be agreed upon or, with the consent of Landlord, the
Tenant, at its own expense, may provide such service subject to Landlord's
supervision.

9.       BUILDING OPERATION - Landlord shall, at its own cost and expense,
furnish all materials, labor and services necessary for the operation,
maintenance and repair of the Landlord's premises, except as hereafter
provided.

10.      INSURANCE - Landlord shall, during the entire term or any extensions
or renewals hereof, keep the Landlord's premises and all improvements thereon
insured against damage by fire and those risks covered by extended coverage, as
provided in a Standard Fire Insurance Policy together with all risks, extended
perils coverage, in amounts sufficient to equal the full current replaceable
cost thereof which is not otherwise insured.  In addition, Landlord shall,
during the entire term and during any extensions or renewals thereof, keep in
full force and effect public liability insurance with respect to the Landlord's
premises, its parking areas, drives, sidewalks and approaches, which are not
otherwise insured.  Such insurance shall be in the amount of $10,000 as to
theft, loss of and damage to any vehicle which may enter the Landlord's
premises, and its contents, and in the amount of $500,000 in respect of injury
to any one person (including loss of life), and $1,000,000 to injury to two or
more persons (including loss of life), arising in any one accident or disaster.

         Tenant shall indemnify and hold Landlord harmless from any liability
for damages to any person or property in, on or about the demised premises from
any cause whatsoever, excepting that caused by the negligence of the Landlord,
his agents or employees.  Tenant shall procure and keep in effect during the
entire term hereof public liability and property damage insurance protecting
Landlord and Tenant from all causes including their own negligence, having as
limits of liability Five Hundred Thousand ($500,000) Dollars for damages
resulting to one person, Five Hundred Thousand ($500,000) Dollars for damages
resulting from one casualty, and Five Hundred Thousand ($500,000) Dollars for
property damage resulting from any one occurrence.  Tenant shall deliver
policies of such insurance or certificates thereof to Landlord, and in the
event Tenant shall fail to procure such insurance, Landlord may at its option
procure the same for the





                                       2
<PAGE>   3

account of Tenant, and the cost thereof shall be paid to Landlord as additional
rent upon receipt by Tenant of bills therefor.

11.      ADJUSTMENT OF RENTAL - For each lease year, the Tenant shall pay to
Landlord a pro rata share of any excess of the annualized cost to Landlord of
performing its duties under paragraph 8 through 10 of this Lease, over the
annualized cost to Landlord of performing such duties during the base year.
The base year is defined as the earlier of the calendar year in which this
lease was dated or the calendar year in which the Tenant first became a tenant
of any part of Landlord's premises.  Tenant's pro rata share shall be
determined by the ratio, the numerator of which is the total amount of square
feet of floor area in the demised premises and the denominator of which is the
total number of square feet of all floor area under Lease in the Landlord's
premises.  At the end of each lease year or partial lease year, Landlord shall
furnish Tenant a statement showing in reasonable detail for the applicable
period all amounts paid or payable for performance of Landlord's duties and
Tenant's proportionate share of any excess cost, as defined herein.  All
amounts required to be paid hereunder shall be paid within fifteen (15) days
after the statement is submitted to Tenant by Landlord.  Certification by
Landlord's Architect of the amount of floor area shall be binding on the
parties hereto.

12.      SECURITY DEPOSIT - Landlord herewith acknowledges the receipt of Five
Thousand Dollars ($5,000) which it is to retain as security for the faithful
performance of all the covenants, conditions and agreements of this Lease.
Landlord may, but shall not be required to, apply the same upon rents or other
charges in arrears or upon damages for Tenant's failure to perform the said
covenants, conditions and agreements; and Landlord's right to the possession of
the premises for non-payment of rent or for any other reason shall not in any
event be affected because Landlord holds this security.  The said sum, if not
applied toward the payment of rent in arrears or toward the payment of damages
suffered by Landlord by reason of the Tenant's breach of the covenants,
conditions and agreements of this Lease, is to be returned to Tenant when this
Lease is terminated, according to its terms, and in no event is the said
security to be returned until Tenant has vacated the premises and delivered
possession to Landlord.  In the event that Landlord repossesses himself of the
said premises because of Tenant's default or because of Tenant's failure to
carry out the covenants, conditions and agreements of this Lease, Landlord may
apply the said security upon all damages suffered to the date of said
repossession and may retain the said security to apply upon such damages as may
be suffered or shall accrue thereafter by reason of Tenant's default or breach.
Landlord shall not be obligated to keep the said security as a separate fund,
but may mix the said security with his own funds.  In the event of any rightful
and permitted assignment of this Lease, the said security deposit shall be
deemed to be held by Landlord as a deposit made by the assignee and Landlord
shall have no further liability with respect to the return of said security
deposit to the assignor.

         Tenant hereby agrees not to look to Mortgagee, as Mortgagee, mortgagee
in possession, or successor in title to the property, for accountability for
any security deposit required by the Landlord hereinunder, unless said sums
have actually been received by said Mortgagee as security for the Tenant's
performance of this lease.

13.      REPAIRS AND ALTERATIONS - Landlord, after receiving written notice
from Tenant, and having reasonable opportunity thereafter to obtain the
necessary workmen, agrees to keep in good repair, the common areas of the
premises, the foundation, roof and four outer walls, including windows and
doors in the premises.  Tenant shall pay or reimburse Landlord for the cost of
all such repairs arising out of the acts of Tenant, its officers, agents '
employees or invitees.  Except as hereinbefore provided, Tenant agrees to
maintain and keep the demised premises in good repair and condition.  Where
Tenant fails to maintain and repair the demised premises, Landlord may, at its
election, perform such duty at Tenant's expense.





                                       3
<PAGE>   4


         The Tenant shall not make any alterations, additions or improvements
to said premises without prior consent of Landlord, which shall not be
unreasonably withheld.  All such alterations, additions or improvements shall
become the property of Landlord and remain upon and be surrendered with the
demised premises.

         Landlord shall have the right to enter upon the demised premises at
all reasonable hours for the purpose of inspecting and making repairs or
improvements to the same or adjoining premises, or the building of which they
are a part.  Where practical, Landlord shall consult with Tenant to minimize
any disruption of Tenant's business.

14.      NON-LIABILITY - Landlord shall not be responsible or liable to Tenant
for any loss or damage that may be occasioned by or through the acts of
omissions of persons occupying adjoining premises or any part of the premises
adjacent to or connected with the demised premises or any part of the building
of which the demised premises are a part or for any loss or damage resulting to
Tenant or his property from burst, stopped or leaking water, gas, sewer or
steam pipes, or for any damage or loss of property within the demised premises
from any cause whatsoever excepting that caused by the negligence of the
Landlord, his agents or employees.  In the event of any sale or transfer
(including any transfer by operation of law) of the demised premises, Landlord
(and any subsequent owner of the demised premises making such a transfer) shall
be relieved from any and all obligations and liabilities under this Lease
except such obligations and liabilities as shall have arisen during Landlord's
(or such subsequent owner's) respective period of ownership, provided that the
transferee assumes in writing all the obligations of the Landlord under this
Lease.

15.      ASSIGNMENT - Tenant shall not assign, or in any manner transfer, this
Lease or any rights or interest herein or sublet the demised premises or any
part thereof without the prior written consent of Landlord, which consent shall
not be unreasonably withheld.

         In the event the estate created hereby shall be taken in execution or
by other process of law, or if Tenant shall be adjudicated insolvent or
bankrupt pursuant to the provisions of any state or federal insolvency or
bankruptcy law, or if a receiver or trustee of the property of Tenant shall be
appointed by reason of Tenant's insolvency or inability to pay its debts, or if
any assignment shall be made of Tenant's property for the benefit of creditors,
or if Tenant shall suffer any lien, levy, or encumbrance to be filed against
the demised premises then and in any of such events, Landlord may terminate
this Lease by written notice to Tenant; provided, however, if the order of
court creating any of such disabilities shall not be final by reason of
pendency of such proceedings, or appeal from such order, and Tenant is acting
to contest or remove such disabilities, then Landlord shall not have the right
to terminate this Lease so long as Tenant performs its obligations hereunder.

         Landlord reserves the right to subject and subordinate this Lease at
all times to the lien of any mortgage or mortgages now or hereafter placed upon
Landlord's interest in the demised premises and on the land and buildings of
which the demised premises are a part or upon any buildings hereafter placed
upon the land of which the demised premises are a part; provided, however, no
default by Landlord under any such mortgage shall affect Tenant's rights
hereunder so long as Tenant is not in default under this Lease.

16.      CASUALTY LOSS - In case of damage to the demised premises or other
part of the building by fire or other casualty, Landlord, unless it elects to
terminate this Lease as provided hereafter, shall repair the damage, to the
extent of its insurance coverage, with reasonable dispatch after notice of the
damage.  Repair by Landlord of any damage caused by carelessness, negligence or
improper conduct of Tenant, its agents, employees, visitors or licensees shall
not prejudice any right of Landlord or its insurer.  If any part of the demised
premises is so





                                       4
<PAGE>   5

damaged by fire or other casualty that they are untenantable but are
nevertheless repaired by Landlord, then the rent shall be adjusted for the time
during which and the extent to which the premises may have been untenantable.
If such repairs are delayed because of Tenant's failure to adjust Tenant's own
insurance claim, or because of Tenant's failure to remove its damaged property,
no reduction shall be made beyond a reasonable time allowed for such adjustment
or removal.  If the fire or damage to the premises be caused by carelessness,
negligence or improper conduct by Tenant or its agents, employees, visitors or
licensees, then notwithstanding such damage, Tenant shall be liable for the
rent, during the unexpired portion of the term of this Lease without abatement,
unless Landlord elects to terminate this Lease as provided hereafter.  If
Landlord, in its uncontrolled discretion, shall decide within a reasonable time
after any fire or other casualty (even though the demised premises may not have
been affected by such fire or casualty) to demolish, rebuild, or reconstruct,
or not to repair the building containing the demise premises, then upon written
notice given by Landlord to Tenant, this Lease shall terminate on a date
specified in such notice as if that date had been originally fixed as the
expiration of the term of this Lease and the rent shall be adjusted as of the
time of the occurrence of any such fire or other casualty.

17.      CONDEMNATION - In the event that any part of the premises shall be
taken or condemned either permanently or temporarily by any competent authority
in appropriation proceedings or by any right of eminent domain, then the terms
of this Lease shall cease and terminate as of the date of title vests in the
condemnor and all rentals shall be paid up to that date, and the Tenant shall
have no claim against the Landlord for the value of any unexpired term of this
Lease.  In the event any portion of the building, exclusive of the demised
premises, shall be taken or condemned as aforesaid, then Landlord may terminate
this Lease by Notice in writing to Tenant given within thirty (30) days after
the date title vests in the condemnor, and Tenant shall thereupon surrender
possession of the demised premises to Landlord.  In the event Landlord does not
so terminate this Lease, Landlord, to the extent of the condemnation award,
shall repair and restore the portion of the building not affected by the taking
so as to constitute the remaining portion of the building a complete
architectural unit.  Tenant shall have no interest in any award resulting from
any condemnation proceedings, except that Tenant shall be entitled to claim,
prove and receive in such proceedings such award as may be allowed Tenant for
loss of business, provided such award shall be in addition to the award of land
and buildings, or portion thereof, containing the demised premises.

18.      REGULATIONS - Tenant covenants and agrees that Tenant, its agents,
employees, visitors and licensees shall comply with the following rules and
regulations and such additional rules and regulations as Landlord may, in its
reasonable discretion prescribe:
         (a)     Tenant shall not conduct or permit to be conducted within the
Landlord's premises any business, nor permit any act, nor store any material,
supplies or equipment, which will tend to increase the premiums for hazard,
fire and other insurance on said premises.
         (b)     Tenant shall not permit any merchandise or goods to be sold or
stored for sale in the demised premises.
         (c)     Tenant shall not permit any goods, boxes, papers, trash or
other articles or materials to be placed in the common areas of the Landlord's
premises.
         (d)     Tenant shall not permit the installation of any vending
machines in the demised premises.
         (e)     No electric or other wires for any purpose shall be brought
into the demised premises without Landlord's written permission specifying the
manner in which same may be done.  No boring, cutting or stringing of wires
shall be done without Landlord's prior written consent.  Tenant shall not
disturb or in any way interfere with the electric light fixtures and all work
upon or alterations to the same shall be done by persons authorized by
Landlord.

         (f)     No bicycle or other vehicle, and no dog or other animal shall

         (g)     No machinery, equipment, office paraphernalia or fixtures,
e.g., safes, vaults, file cabinets, telephone apparatus, computing machinery or
electronic devices, of a weight that might overload the floors of supporting
columns or walls of the demised premises shall be installed except as permitted
by the Landlord in writing, and the Landlord at his sole option may place or
install any such machinery, equipment, office paraphernalia or fixtures and
charge the reasonable cost of such placement to the Tenant; provided always
that the Tenant shall be liable in all events of damage occasioned to the
premises or to any property of the Tenant or other Tenants in the building by
reason of overloading the floors.
         (h)     No additional lock or locks shall be placed on any door in the
building without Landlord's prior written consent.  A reasonable number of keys
will be furnished by Landlord, and Tenant shall not make or permit any
duplicate keys to be made.
         (i)     Tenant shall not use any duplicating equipment emitting
noxious fumes, unless same are properly vented at Tenant's expense.
         (j)     Water closets and other toilet fixtures shall not be used for
any purpose other than that for which the same is intended, and any damage
resulting to same from Tenant's misuse shall be paid for by Tenant.  No person
shall waste water by interfering or tampering with the faucets or otherwise.
         (k)     Tenant shall not interfere, in any way, with other Tenants,
their guest, customers or invitees.

19.      SIGNS - A sign containing the Tenant's advertised name and suite
number and no other words or symbols shall be provided and installed by
Landlord, at Tenant's expense, on the exterior of the demised premises and on a
directory to be installed by Landlord within the entry way of the building.
The size, color, location, material and letter style shall be approved by
Landlord.  Tenant shall not permit any other picture, lettering, notice or
advertisement of any kind to be installed on or displayed from the windows,

premises are located without Landlord's consent.

20.      STATEMENTS - Tenant agrees to furnish Landlord, upon request at any
time after the term of this Lease has commenced, a letter addressed to
Landlord's mortgage or financial institution giving the following information:
That Tenant has accepted possession, subject to the terms of this Lease; the
commencement and expiration dates of this Lease; the date when rent commenced;
and that this Lease is in full force and effect.  Failure of Tenant to provide
Landlord at the request of Landlord's mortgagee or financial institution such a
letter as above described shall give Landlord the right to cancel this Lease
upon (5) day's prior written notice to Tenant of such cancellation and Tenant
shall remain liable to Landlord for any damages sustained by the Landlord
because of such failure by Tenant.

21.      RENEWAL OPTION - This Lease shall stand renewed for successive
additional terms of one lease year, unless either party shall, not less than 90
days prior to the end of the term hereof, or not less than 90 days prior to the
end of any renewal term, by written notice to the other party, terminate this
Lease.  All of the terms and conditions of this Lease shall apply to the
parties hereto during said renewal terms as though such renewal terms were part
of the original term of this Lease.  The rent during said renewal term shall be
negotiated between the parties within the 90 day period preceding each renewal.
In the event the parties hereto cannot come to an agreement on the rent to be
applied during the renewal period prior to the commencement of the renewal
period (the "Anniversary Date"), the lease will be terminated 90 days from the
Anniversary Date.  In the event the parties come to an agreement regarding the
terms and conditions of the renewal, the Tenant agrees to pay the renewal
monthly base rent in the same manner and under all of the same terms and
conditions as though said adjusted base rent were set forth in paragraph 4
hereof.

22.      RE-RENTING - Landlord shall also have the right to enter upon the
demised premises for a period commencing one hundred and twenty (120) days
prior to the termination of this Lease and all renewals or extensions thereof,
for the purpose of exhibiting the same to prospective tenants or purchasers.
During said period Landlord may place signs in or upon said premises to
indicate that the same are for rent or sale, which signs shall not be
alterated, removed, obliterated or hidden by Tenant.

23.      REMEDIES -

         (a)     Tenant covenants and agrees that:

                 (i)      If Tenant shall fail, neglect or refuse to pay any
installment of rent at the time and in the amount as herein provided or to pay
any other monies, payments or charges agreed by it to be paid, promptly when
and as the same shall become due and payable under the terms herein and if any
such default should continue for a period of more than ten (10) days; or

                 (ii)     If Tenant shall abandon or vacate the demised
premises or shall fail, neglect or refuse to keep and perform any of the other
terms, covenants, conditions, stipulations, obligations or agreements herein
contained and covenanted and agreed to be kept and performed by it, and in the
event any such default shall continue for a period of more than fifteen (15)
days after notice thereof given in writing to Tenant by Landlord (provided,
however, that if the cause for giving such notice involves the making of
repairs or other matters which reasonably require a longer period of time than
the period of such notice, Tenant shall be deemed to have complied with such
notice so long as it has commenced to comply with said notice within the period
set forth in said notice and is diligently procuring compliance, or has taken
proper steps or proceedings under the circumstance to prevent the seizure,
destruction, alteration or other interference with said demised premises by
reason of noncompliance with the requirements of any law or ordinance or with
the rules, regulations, or directions of any governmental authority as the case
may be); then Landlord, besides other rights or remedies it may have by law,
shall be entitled to the rights and remedies enumerated below.

         (b)     In the event a default enumerated in subparagraph (a) of this
paragraph shall occur, Landlord shall be entitled to all the rights and
remedies of Landlord herein enumerated, which rights and remedies shall be
cumulative and non-exclusive and none shall exclude any other right or remedy
allowed by law.  Such rights and remedies may be exercised concurrently and
whenever and as often as the occasion therefor arises:

                 (i)      Tenant does hereby authorize and fully empower
Landlord or Landlord's agent at one to re-enter and take possession of the
demised premises immediately, and by reasonable force if necessary, without any
previous notice of intention to re-enter or resort to legal process, and to
remove all persons and property from the demised premises, and to use such
force and assistance in effecting and perfecting such removal of said persons
and property as may be necessary and advisable to recover exclusive possession
of all said demised premises, whether in the possession of Tenant or of third
persons or otherwise, without being deemed guilty in any manner of trespass,
without becoming liable for any loss or damage occasioned thereby, and without
prejudice to any remedies which might otherwise be used by Landlord, and to
store said property in a warehouse or elsewhere at the cost of and for the
account of Tenant.

                 (ii)     Should Landlord elect to re-enter and take
possession, as herein provided, or should it re-enter or take possession
pursuant to legal proceedings or pursuant to any notice provided for by law,
Landlord may either terminate this Lease, or Landlord may, from time to time
without terminating this Lease, make such alterations and repairs as may be
necessary in order to relet the premises, and relet said premises or any part
thereof for such term or terms





                                       7
<PAGE>   8

(which may be for a term extending beyond the term of this Lease) and as such
rental or rentals and upon such other terms and conditions as Landlord in its
sole discretion may deem advisable.  Upon each such reletting, all rentals
received by Landlord from such reletting shall be applied, first, to the
payment of any damages or indebtedness other than rent due hereunder from
Tenant to Landlord; second, to the payment of any costs and expenses of ouch
reletting, including brokerage fees, attorney's fees and cost of such
alterations and repairs; third, to the payment of rent due and unpaid
hereunder, and the residue, if any, shall be held by Landlord and applied to
payment of future rent as the same may become due and payable hereunder.  If
such rentals received from such reletting during any month are less than that
to be paid during that month by Tenant hereunder, Tenant shall promptly pay any
such deficiency to Landlord.  Landlord reserves the right to bring any action
or legal proceeding for the recovery of any deficits remaining unpaid as
Landlord may deem favorable, from time to time, without being obliged to wait
until the end of the term hereof or any renewals or extensions thereof, for the
final determination of Tenant's account.  No such reentry or taking possession
of said premises by Landlord shall be construed as an election on Landlord's
part to terminate this lease unless a written notice of such intention be given
to Tenant by Landlord or unless the termination hereof be decreed by a Court of
competent jurisdiction.

                 (iii)  Notwithstanding any such reletting without termination,
Landlord may at any time elect to terminate this Lease for any breach or
default by Tenant.  Should Landlord at any time terminate this Lease for any
breach or default, then, in addition to any other remedies Landlord may have,
it may recover from Tenant all damages it may incur by reason of such breach,
including the cost of recovering the demised premises, reasonable attorneys
fees, and all indebtedness due it by Tenant, including the worth at the time of
payment of the excess, if any, of the amount of all rent and other payments
reserved in this Lease for the remainder of the stated term over the then
reasonable rental value of the demised premises for the remainder of the stated
term, all of which amounts shall be immediately due and payable from Tenant to
Landlord.

         In determining the reasonable rental value of the demised premises for
the remainder of the stated term, the value of the actual rental obligations of
the Tenant, if any, to whom the Landlord has relet the demised premises shall
be considered the then reasonable rental value and no reasonable rental value
shall be allowed as an offset of Tenant's obligation hereunder until the
expiration of a reasonable period after Landlord shall have leased all other
similar spaces in the Landlord's premises.

         (c)     No waiver of any term, obligation, covenant or condition or of
the breach of any terms, obligation, covenant or condition of this Lease shall
constitute a waiver of any subsequent breach of such term, obligation, covenant
or condition or shall justify or authorize the non-observance on any other
occasion of the same or of any other term, obligation, covenant or condition
hereof, nor shall the acceptance of rent or other payment by Landlord at any
time when Tenant is in default under any term, obligation, covenant or
condition hereof constitute a waiver of such default or of Landlord's right to
terminate this Lease or of any of Landlord's other rights on account of such
default, nor shall any waiver or indulgence granted by Landlord to Tenant be
taken as an estoppel against Landlord.

         (d)     Landlord shall in no event be charged with default in the
performance of any of its obligations hereunder and Tenant shall have no right
to cure such default unless and until Landlord shall have failed to commence
performance of such obligation within thirty (30) days (or such additional time
as is reasonably required to commence correction of such default) after notice
to Landlord by Tenant properly specifying wherein Landlord has failed to
perform any such obligations.





                                       8

         If the holder of record of the first mortgage covering the demised
premises shall have given prior written notice to Tenant that it is the holder
of said first mortgage and if such notice includes the address at which notices
to such mortgagee are to be sent, then Tenant agrees to give the holder of
record of such first mortgage notice simultaneously with any notice given to
Landlord to correct any default of Landlord as hereinabove provided and agrees
that the holder of record of such first nor gage shall have the right, within
sixty (60) days after receipt of said notice, to correct or remedy such default
before Tenant may take any action under this Lease by reason of such default.

24.      CONSTRUCTION - The captions appearing in this Lease are inserted only

         If any term or provision of this Lease or the application thereof to
any person or circumstances shall to any extent be invalid or unenforceable,

persons or circumstances other than those as to which it was held invalid or
unenforceable, shall not be affected thereby and each term and provision of
this Lease shall be valid and enforced to the fullest extent permitted by law.

25.      ENTIRE AGREEMENT - This Lease shall constitute the entire agreement of
the parties hereto; all prior agreements between the parties, whether written
or oral, are merged herein and shall be of no force and effect.  This Lease
cannot be changed, modified or discharged orally but only by an agreement in

modification or discharge is sought.

certified or registered mail, with postage prepaid, and if such notice to
Landlord is in writing addressed to the last known post office address of
Landlord and deposited in the mail, certified or registered mail, with postage
prepaid.  Notice need be sent to only one Tenant or Landlord where Tenant or
Landlord is more than one person.

27.      SUCCESSORS - This Agreement shall inure to the benefit of and be
binding upon the parties hereto, their respective heirs, administrators,

         Landlord and Tenant shall, at their own respective expense, perform
the additional work described as "Landlord's Work" or "Tenant's Work" in
Exhibit C attached hereto and incorporated herein by reference.  It is
expressly understood and agreed that Landlord's obligation with respect to the
construction and finishing of the Demised Premises shall be limited to the
scope of work described as Landlord's Work in Exhibit C and shall in no event
include any work not described in Exhibit C.  All Landlord's Work and Tenant's
Work shall constitute improvements to the Demised Premises which shall become
sole property of Landlord and shall remain at the Demised Premises upon
expiration of this Lease Agreement or termination of Tenant's right to
possession of the Demised Premises unless Landlord notifies Tenant otherwise in
writing.  Possession of the Demised Premises shall be delivered to Tenant on or
before the Commencement Date, subject to extension for all delays resulting
from causes beyond the reasonable control of Landlord.  All work by Tenant or
Landlord shall be performed in a lawful and workmanlike manner in accordance
with all ordinances, building codes or other governing law and in accordance
with plans and specifications prepared by Tenant at Tenant's sole cost and
expense and approved by Landlord, which approval Landlord may grant or withhold
in Landlord's sole discretion.  Tenant shall take no action which may result in
a claim of lien against the Tract, Building or Demised Premises and Tenant
shall liquidate and discharge the same as provided in Section 12.

         Tenant shall provide Landlord with construction drawings for ALL
MATERIAL improvements and changes it makes to the Premises, and shall provide
Landlord with updated "as built" space plans on a periodic basis.

Tenant shall promptly and timely pay as additional rent all ad valorem taxes
LEVIED AGAINST THE TRACT, or assessments levied by any federal, state, county,
or municipal authority on Tenant's personal property in or on the Demised
Premises.

         (b)     Tenant shall pay as additional rent within thirty (30) days of
billing by Landlord Tenant's share as below defined of the amount of ad valorem
taxes LEVIED AGAINST THE TRACT, or assessments levied from time to time by the
foregoing authorities ON TENANT'S PERSONAL PROPERTY AS STATED IN PARAGRAPH 4
ABOVE.  THE FOREGOING





                                      -3-
<PAGE>   4

LIMITATION RELATIVE TO PERSONAL PROPERTY OF TENANT SHALL APPLY TO ASSESSMENTS
ONLY AND SHALL IN NO WAY LIMIT OR APPLY TO AD VALOREM TAXES DURING THE TERM
HEREOF AND ANY EXTENSION OR HOLDOVER PERIOD.  Tenant's share as used herein
shall be the difference in Base Year (actual taxes paid in 1993) and actual tax
costs for succeeding calendar years.  Landlord may estimate Tenant's pro rata
share of such taxes and assessments and Tenant shall pay such estimated amount
as additional rent with Tenant's payment of monthly minimum rent.  In the event
Tenant's actual prorata share exceeds its estimated share, Tenant shall pay the
deficiency to Landlord as additional rent within thirty (30) days of billing by
Landlord.  In the event Tenant's actual prorata share is less than its
estimated share, Landlord shall credit the amount thereof to the monthly rents
next becoming due from Tenant.

                                       6.

         Landlord hereby grants Tenant and Tenant's invitees, licensees and

CASUALTY, LANDLORD SHALL GIVE TENANT NOTICE OF ITS INTENTION TO REPAIR OR
RESTORE WITHIN 15 DAYS AFTER THE OCCURRENCE OF SUCH DAMAGE.  If the Demised
Premises shall be damaged by fire or other casualty, which damage can
reasonably be corrected within ONE HUNDRED FIFTY (150) days and for a sum not
exceeding the insurance proceeds actually received therefor by Landlord,
Landlord shall be entitled to RESTORE AND REPAIR THE DEMISED PREMISES, retain
any excess insurance proceeds, AND TENANT SHALL BE OBLIGATED TO REOCCUPY THE
PREMISES UPON COMPLETION OF SUCH REPAIRS WITH TENANT'S SOLE REMEDY BEING THE
ABATEMENT OF RENT IN THE PORTION OF THE DEMISED PREMISES WHICH WERE NOT

or replaced, either Landlord or Tenant may terminate this Lease Agreement by
written notice to the other provided, however, that (i) Tenant may not
terminate this Lease Agreement after Landlord has begun to repair or
reconstruct the Demised Premises and (ii) any obligations of the parties
existing under this Lease Agreement at the time of such termination shall be
unaffected by such termination, provided however there shall be an equitable
abatement of rent proportionate to the demised premises damaged by fire or
casualty and (iii) in the event such casualty occurs during the last twelve
(12) calendar months of the term or any extended term, Landlord may elect not
to rebuild and may retain the insurance proceeds received.

         (b)     In the event the whole of the Demised Premises shall be taken
by any public authority under the power of eminent domain or like power or by a
deed in lieu thereof, this Lease Agreement shall terminate as of the date that
possession of the Demised Premises





                                      -9-
<PAGE>   10

shall be delivered to the appropriate authority.  In the event of only a
partial such taking, this Lease Agreement shall not terminate (unless either
party, by written notice to the other party, chooses to terminate the same) but
there shall be an equitable abatement of rent proportionate to the part of the
Demised Premises taken.  Any termination of the Lease Agreement shall not
affect the obligations of the parties existing under the Lease Agreement up to
the time of termination.  Tenant shall not be eligible to receive any part of
any award or awards from any eminent domain proceeds or deed in lieu thereof,
and Tenant hereby assigns all of its right, title and interest in and to any
such award or awards to Landlord.  However, Tenant may, to the extent permitted
by law, and at Tenant's own expense and cost, take independent or related
proceedings against the public authority exercising the power of eminent domain
to pursue and establish any damages Tenant may have incurred for the taking of
Tenant's property and for business interruption or relocation expenses
resulting from the exercise of power of eminent domain (including any deed in
lieu thereof) provided that any such action by Tenant shall not reduce or
adversely affect the amount of Landlord's award.

                                      16.
                                   INSURANCE

         (a)     Throughout the term of this Lease Agreement and any extended
term or terms, Landlord shall provide fire and extended insurance coverage for

foundation and footings) in a form and amount satisfactory to Landlord as
provided in Section 6 above WHICH INSURANCE SHALL BE OBTAINED FROM A COMPANY
RATED AAA BY BEST & COMPANY AND SHALL BE IN FORM REASONABLY ACCEPTABLE TO
TENANT.  The costs of such insurance (as well as the costs of any other
insurance of any nature that Landlord shall choose to obtain for the Building,
Common Areas, Tract or any part thereof) shall be one of Landlord's Operating
Expenses reimbursable to Landlord in accordance with Section 6 above.
Throughout the term of this Lease Agreement and any extended term or hold over
period, Tenant shall provide, at Tenant's sole cost and expense, in addition to
the fire and extended insurance coverage for Tenant's property at the Demised
Premises required by this lease, public liability insurance for the Demised
Premises, including property damage with no less than One Million Dollars
($1,000,000.00) limit per occurrence and death and personal injury coverage
with no less than One Million Dollars ($1,000,000.00) limit per person.  Such
policy shall name Landlord as an additional insured.  Tenant shall also
maintain all worker's compensation and similar insurance required by applicable
law.

         (b)     With respect to all policies of insurance required to be
carried by either party under this Lease Agreement, either party





                                      -10-
<PAGE>   11

shall provide the other party with copies of the certificates of such insurance
at or prior to their effective dates.  All such policies of either party shall
provide that the same may not be modified or cancelled without at least thirty
(30) days prior written notice to the other party and either party shall
provide the other party with copies of the certificates for all modified,
renewed or new insurance policies on or before their effective dates.

         (c)     To the extent possible without additional cost, each party
shall obtain, for each policy of insurance, provisions permitting waiver of any
claim against the other party for loss or damage within the scope of the
insurance.  Such waiver coverage at an additional premium shall be obtained by
either party upon written notice from the other party seeking the same
accompanied by reimbursement by such other party for the additional expense.

         (d)     Tenant shall not take any action or permit anything to be done
which will increase the rate of fire or other insurance coverage on the Demised
Premises or any part thereof or adjacent thereto or on the Building or the
Tract.  However, in the event the Tenant shall take any such action then, in
addition to any other rights Landlord might have under this Lease Agreement or
otherwise, Landlord may require Tenant, upon demand, separately to pay or
reimburse Landlord as additional rent the amount of any increased insurance
premiums attributable to such action which are in excess of those charged at
the date of this Lease Agreement.

                                      17.
                             WAIVER OF SUBROGATION

         (a)     Landlord hereby releases Tenant, but only to the extent of
Landlord's insurance coverage and only to the extent payment is actually
received under such coverage by Landlord, from any liability for loss or damage
covered by any insurance policies which the Landlord carries with respect to
the Demised Premises, Building or Tract or any interest or property therein or
thereon whether or not such insurance is required by this Lease Agreement and
even if the insured peril shall be brought about by the default, negligence or
other action of the Tenant, Tenant's agents, employees or any of them;
provided, this release shall be in effect only with respect to an insured loss
only so long as Landlord's policy applicable to such loss contains a clause to
the effect that this release shall not affect the right of Landlord to recover
under such policy.  Landlord does not waive and hereby reserves the right to
secure compensation from Tenant for any uninsured loss, any amounts not paid
because of deductibles and other amounts not paid for any reason whatsoever
OTHER THAN FOR LANDLORD'S FAILURE TO MAINTAIN INSURANCE UNDER SECTION 16.

         (b)     Tenant hereby releases Landlord, but only to the extent of
Tenant's insurance coverage and only to the extent payment is





                                      -11-
<PAGE>   12

actually received under such coverage, from any liability for loss or damage
covered by any insurance policies which the Tenant carries with respect to the
Demised Premises, Building or Tract or any interest or property therein or
thereon whether or not such insurance is required by this Lease Agreement and
even if the insured peril shall be brought about by the default, negligence or
other action of the Landlord, Landlord's agents, employees or any of them;
provided, this release shall be in effect only with respect to an insured loss
and only so long as Tenant's policy applicable to such loss contains a clause
to the effect that this release shall not affect the right of Tenant to recover
under such policy.  Tenant does not waive and hereby reserves the right to
secure compensation from Landlord to which Tenant is otherwise entitled for an
uninsured loss, any amounts not paid because of deductibles and other amounts
not paid for any reason whatsoever.  This section does not modify the
limitations of Landlord's liability to Tenant provided under any other sections

Agreement, Tenant shall leave the Demised Premises broom clean, shall fasten
and lock all doors and windows, shall return to Landlord all keys to the
Demised Premises, and shall notify Landlord of the address to which any balance
of the Security Deposit should be sent.

         (b)     Any holding over by Tenant at the Demised Premises after the
expiration of the term of this Lease Agreement or any final extended term shall
at most result in a tenancy from month to month, terminable at will of
Landlord.  All of the obligations of Tenant under this Lease Agreement shall
apply to any such hold over period, except that the monthly portion of the Base
Rent shall be ONE HUNDRED TWENTY FIVE PERCENT (125%) in amount of each month

         (c)     Upon vacating the Premises, Tenant must have performed an
environmental audit to ensure that the facility is free of any materials and
residue which might be contaminated with any materials potentially hazardous to
health.  UPON VACATING THE PREMISES, TENANT WILL PROVIDE DOCUMENTATION THAT THE
PREMISES ARE FREE OF POTENTIALLY HAZARDOUS MATERIALS TO THE SAME EXTENT AND
LEVEL USING SIMILAR METHODOLOGY (WITH THE SAME DEGREE OF TECHNOLOGY AVAILABLE
ON JANUARY 1, 1994), AS SPECIFIED IN (I) THE GLAXO LETTER OF CERTIFICATION

              REMOVAL OF FIXTURES AND OTHER ITEMS AT END OF LEASE

         To the extent consistent with other terms of this Lease Agreement,
Tenant at the expiration of this Lease Agreement shall remove all furniture and
other personal property, including fixtures, trade or otherwise, which Tenant
or any other third parties have installed upon or placed within the Demised
Premises during the term of this Lease Agreement or any extended term or
holdover period and to which Landlord is not entitled if such items can be
removed without material injury to the Demised Premises; provided, however, all
repairs to the Demised Premises required by such removal must be properly and
promptly made by Tenant at Tenant's sole cost and expense incident to such
removal.   All property of Tenant remaining at the Demised Premises after the
last day of the term of this Lease Agreement or any extended term or holdover
period shall conclusively be deemed abandoned and may be removed by Landlord at
Tenant's expense or retained by Landlord.

                                      20.
                                LANDLORD'S ENTRY

         Landlord at all reasonable times AND UPON PRIOR NOTICE may enter to
view or inspect the Demised Premises and to make repairs which Landlord may see
fit to make in accordance with Section 9 or otherwise, EXCEPT EMERGENCY REPAIRS
FOR WHICH LANDLORD IS RESPONSIBLE AND FOR WHICH LANDLORD SHALL NOT BE OBLIGATED
TO GIVE PRIOR NOTICE.  During a reasonable period not less than six (6) months
preceding the expiration of the initial or any extended term and throughout any
holdover period Tenant will permit Landlord to place and keep upon and about
the Demised Premises a notice that the Demised Premises are for rent or for
sale and during such period Landlord may enter the Demised Premises to show
them to prospective tenants or purchasers.  LANDLORD ACKNOWLEDGES THE
CONFIDENTIAL NATURE OF TENANT'S BUSINESS OPERATIONS AND AGREES TO USE ITS BEST
EFFORTS NOT TO DISRUPT ORDINARY BUSINESS OPERATIONS IN EXERCISING ANY OF THE
RIGHTS GRANTED HEREIN.

                                      21.
                             RULES AND REGULATIONS

         Tenant shall comply with the rules and regulations attached as Exhibit

                                QUIET ENJOYMENT

         Landlord agrees that if Tenant shall pay the rent as aforesaid and
perform the covenants and agreements herein contained on Tenant's part to be
paid and performed, Tenant shall peaceably hold and enjoy the Demised Premises
without hindrance or interruption by the Landlord or by any other person or
persons claiming through Landlord, DIRECTLY OR INDIRECTLY.

                                      23.
                      SUBORDINATION AND TENANT'S ESTOPPEL

         (a)     This Lease Agreement shall be deemed subject and subordinate
to any mortgage or deed of trust which may heretofore or hereafter be executed
by Landlord covering the Demised Premises or any part thereof or the Building
or the Tract and to all renewals, modifications or extensions thereof.  The
Landlord's interest in this Lease Agreement may be assigned as security for any
financing now or hereafter required by Landlord.  In the event any proceedings
are brought or notice given for foreclosure of any mortgage or deed of trust on
the Demised Premises or the Building or for the exercise of any rights pursuant
to any mortgage, deed of trust or assignment Tenant will attorn to the holder
of the deed of trust, mortgagee, assignee or purchaser at a foreclosure sale,
as the case may be and will recognize such holder, assignee, mortgagee or
purchaser as Landlord, providing such holder, assignee, mortgagee or purchaser
agrees not to disturb Tenant's possession so long as Tenant is not in default
under the terms of this Lease Agreement.

         (b)     Tenant shall execute and deliver to Landlord at Landlord's
request from time to time, and within TEN (10) BUSINESS days thereof (i)
instruments evidencing the subordination position of this Lease Agreement
and/or (ii) estoppel certificates setting forth the date Tenant accepted
possession of the Demised Premises, that Tenant occupies the Demised Premises,
the termination date of the Lease Agreement, the date to which rent has been
paid, and the amount of monthly rent in effect as of such certification,
whether or not Tenant has any defense to the enforcement of Tenant's lease, any
knowledge Tenant has of any default or breach by Landlord, any other matters
requested by Landlord and that the Lease Agreement is in full force and effect
except as to modifications, agreements or amendments thereto, copies of each of
which including the Lease Agreement shall be attached.  Failure by Tenant to
RESPOND TO any such request within such TEN (10) BUSINESS day period shall be
deemed a conclusive admission by Tenant that this Lease Agreement remains in
full force and effect, that Tenant has no defense thereto and that Landlord is
not in breach thereunder.

                        CURING DEFAULTS AND LATE CHARGES

         (a)     If Tenant is required to perform or comply with any agreement
or provision hereof and shall fail to do so within the time provided therefor
(or if no time is provided therefor then within ten (10) days after WRITTEN
NOTICE AND demand for compliance shall have been provided to Tenant) then, in
each such case, upon the expiration of the time provided in this Lease
Agreement (except in the case of emergency situations in which event the time
frame may be shortened as appropriate) Landlord may perform and comply
therewith for the account and at the expense of Tenant; and Tenant upon receipt
of an itemized invoice of the cost and expense thereof, agrees to pay as
additional rent within thirty (30) days of billing by Landlord the cost and
expense incurred by Landlord.

         (b)     Tenant shall pay a late charge of the lesser of four percent
(4%) of all sums past due more then fifteen (15) days or the maximum amount
allowed by law and interest at the lesser rate of eighteen percent (18%) per
annum on all past due sums from the due date to the date payment is received or
the maximum amount allowed by law.

         (c)     NOTWITHSTANDING ANYTHING IN THE FOREGOING TO THE CONTRARY, IN
THE EVENT LANDLORD SHALL HAVE GIVEN TENANT WRITTEN NOTICE HEREUNDER TWO (2)
TIMES IN ANY TWELVE (12) CALENDAR MONTH PERIOD DUE TO THE FAILURE OF TENANT TO
MAKE TIMELY PAYMENT HEREUNDER, THEN UPON THE OCCURRENCE OF THE THIRD (3RD)
FAILURE OF TENANT TO MAKE TIMELY PAYMENT WITHIN SUCH TWELVE (12) CALENDAR MONTH
PERIOD, SUCH FAILURE ON THE PART OF TENANT SHALL AUTOMATICALLY CONSTITUTE AN
EVENT OF DEFAULT WITHOUT NECESSITY FOR WRITTEN NOTICE THEREOF FROM LANDLORD.

                                      25.
                               EVENTS OF DEFAULT

         (a)     For purposes of this Lease Agreement, the occurrence of any

                 after written notice is sent by Landlord;

       (iii)     The commencement in any court or tribunal of any proceeding,
                 voluntary or involuntary, to declare Tenant insolvent or
                 unable to pay its debts as and when due;

                 property or assets for the benefit of creditors;

           (v)   The levy or execution, attachment, or taking of the leasehold
                 interest of Tenant HEREUNDER by process of law or otherwise in
                 satisfaction of any judgment, debt or claim OR THE LEVY,
                 EXECUTION, ATTACHMENT OR TAKING OF OTHER PROPERTY OR ASSETS OF
                 TENANT WHICH MATERIALLY ADVERSELY AFFECT TENANT'S ABILITY TO
                 PERFORM TENANT'S OBLIGATIONS HEREUNDER;

          (vi)   Tenant files any petition or action for relief under any
                 creditor's law (including bankruptcy, reorganization, or
                 similar actions), either in state or federal court;

         (vii)   Any petition or action for relief under any creditor's law
                 (including bankruptcy, reorganization, or similar actions),
                 either in state or federal court is filed against Tenant;

        (viii)   Tenant conveys away substantially all of Tenant's assets
without adequate consideration; or

          (ix)   Tenant is dissolved, liquidated, ceases to exist or do
business or becomes insolvent.

         (b)     The remedies of terminating the term, of terminating
possession or otherwise as provided in this Lease Agreement shall be cumulative
and in addition to and not in limitation of any rights and remedies otherwise
available to the Landlord and the exercise of any rights and remedies on
default shall not preclude the exercise of any other rights and remedies
available to the Landlord at law or in equity or otherwise.

                                      26.
             LANDLORD'S RIGHTS ON TERMINATION OF TERM OR POSSESSION

         (a)     Upon any termination of the initial or extended term hereof,
whether by lapse of time or otherwise, or upon any termination of Tenant's
right to possession or occupancy only, without terminating the term hereof,
Tenant shall surrender possession and vacate the Demised Premises and shall
deliver possession thereof to the Landlord; and Tenant hereby grants to
Landlord full and free license to enter into and upon the Demised Premises in
such event to repossess the Demised Premises as of Landlord's former estate and
to expel or remove Tenant and any others who may be occupying the Demised
Premises and to remove therefrom any and all property, without being guilty of
or liable for trespass, eviction or forcible entry or detainer and without
relinquishing Landlord's right to rent or any other right given to Landlord
hereunder or by operation of the laws of the State of North Carolina.  Upon the
occurrence of any Event of Default after





                                      -16-
<PAGE>   17

written notice thereof and the expiration of any applicable time for curing
such Event of Default, Landlord shall be entitled to the rights and remedies
set forth in Paragraph 24 and hereinafter in Paragraph 26.

         (b)     If Landlord elects to terminate Tenant's right to possession
only as above provided, without terminating the term hereof, Landlord at its
option may enter into the Demised Premises, remove Tenant's property and other
evidences of tenancy and take and hold possession thereof without such entry
and possession terminating the term hereof and without releasing Tenant from
its obligation to pay rents and other monetary obligations herein reserved for
the full term hereof.  Upon and after entry into possession without terminating
such obligations, Landlord shall use reasonable efforts to relet the Demised
Premises, or any part for the account of Tenant to any person, firm or
corporation other than Tenant for such reasonable rent, for such time, and upon
such reasonable terms as Landlord in its sole discretion shall determine.  If
any rent is to be collected by Landlord upon any such reletting for Tenant's
Account is not sufficient to pay the full amount of rent or any other rent
herein reserved (including additional rents and other charges) and any other
monetary obligations hereunder, and not heretofore paid by Tenant, together
with the reasonable costs of retaking possession and any repairs, alterations,
or redecoration necessary for such reletting, Tenant shall pay to Landlord the
amount of the entire deficiency upon demand, and if the rent to be collected
from such reletting is more than enough to pay the full amount of the rents
reserved hereunder and all of the aforementioned costs, Landlord shall be
entitled to retain such excess.  In accordance with the foregoing, Tenant shall
continue to be entitled to make timely payment of the aforesaid amounts due
hereunder as and when such payments are due and payable; provided, however, in
the event Tenant shall fail to make any such payment in a timely manner,
Landlord shall have the right and remedy and be entitled to accelerate the rent
and other monetary obligations herein reserved for the full term hereof,
subject to applicable offset or credit as aforesaid.  The obligation of Tenant
to pay rent and other monetary obligations hereunder constitutes evidence of
indebtedness.  Notwithstanding any termination of the right to possession
without termination of the term, the Landlord expressly reserves the right, at
any time after the termination of possession, to terminate the term of this
Lease Agreement by notice of such termination to Tenant.

         (c)     The foregoing rights and remedies of Landlord are in addition
to any other rights and remedies Landlord may have at law or in equity.

                                   NO WAIVER

         The acceptance of rentals and other payments by Landlord for any
period or periods after a default under any of the terms, covenants, and
conditions herein contained to be performed, kept and observed by Tenant shall
not be deemed a waiver of any rights on the part of the Landlord to terminate
this Lease Agreement for any other failure or for the continued failure by
Tenant to so perform, keep or observe its covenants, terms and conditions to be
kept, performed and observe by it.  No waiver by Landlord of any of the terms
or conditions of this Lease Agreement shall be construed as a waiver by
Landlord of any subsequent default on the part of Tenant.

condition of this Lease Agreement upon Landlord's part required to be

or use of the Demised Premises based upon any action or omission of Landlord,
Tenant covenants and agrees to look solely to Landlord's interest in the

DEVELOPMENT AGREEMENT
Page 10 of 16

         Company's account, it shall be handled as follows:

                          (i)     Credit Balances.  In the event the Company's

                 service fees and expenses accrued through the date of
                 reconciliation,  AAI shall issue a credit to the Company in

                 cumulative monthly payments to AAI are less than the
                 cumulative service fees and expenses accrued through the date
                 of reconciliation, the Company shall pay AAI the debit balance
                 within thirty (30) days of the Company's receipt of invoice
                 for said underpayment amount.  Should any part of the invoice
                 be in dispute, the Company covenants to pay the undisputed
                 amount according to the terms and conditions described herein
                 while said dispute is being resolved.

         Section 6.3      AUDIT RIGHTS.  The Company shall have the right, upon
reasonable notice and at its own expense, during AAI's performance of
DEVELOPMENT SERVICES, and for a period of two (2) years thereafter, to conduct
an audit of expenses charged to the Company for such services.  The audit shall

approved by AAI, which approval shall not be unreasonably withheld.  AAI shall
keep a complete and accurate account of expenses charged to the Company and
shall allow the examination of such records by the selected accountant during
regular business hours.  Such audits may be performed no more frequently than
annually.  In the event that such audit reveals that amounts charged by AAI to
the Company for the period commencing on the date of the most recent audit (or
from the date hereof with respect to the initial audit) exceed by 5 percent or
more the amount that AAI may rightfully have charged during such period, AAI
shall reimburse the Company for the expense of such audit.

DEVELOPMENT AGREEMENT
Page 6 of 26


or reject any such proposed deviations from the then current SERVICE ESTIMATE.

addition to the INITIAL PRODUCTS, in which case, the parties shall amend
Schedule 1 of this Agreement accordingly.

         During the term of this Agreement, AAI shall not develop, for its own
account or for any person or entity (other than the Company), any formulation
of a product intended to be THERAPEUTICALLY EQUIVALENT to the reference product
of a NEW PRODUCT; provided, however, that the foregoing restriction shall not
apply:  (i) with respect to a NEW PRODUCT, if the Company has terminated the
development of such NEW PRODUCT hereunder pursuant to Section 7.2 hereof, (ii)
in any country at any time one and one-half years after the first commercial
sale of such NEW PRODUCT in such country if the applicable government authority
has approved ANDA's (or similar documents applicable in such country) for two
or more products in addition to the NEW PRODUCT THERAPEUTICALLY EQUIVALENT to
the reference product of such NEW PRODUCT, (iii) with respect to services
performed by AAI pursuant to an agreement entered into by AAI prior to the
execution of the written agreement by AAI and the Company identifying such NEW
PRODUCT as contemplated by Section 1.20 or (iv) with respect to any NEW PRODUCT
that the Company shall have retained any other firm to perform the services
contemplated hereby pursuant to Section 2.8.  Subject to the foregoing sentence
and Articles III and VIII herein, the parties hereto acknowledge that AAI is
not restricted hereby from performing non-formulation services for its own
account or for third parties with respect to pharmaceutical products.  The
parties further acknowledge that AAI may also provide services

DEVELOPMENT AGREEMENT
Page 7 of 26


(including formulation services) similar to those contemplated herein for other
parties or for its own account with respect to pharmaceutical products other
than products that are intended to be THERAPEUTICALLY EQUIVALENT to the
reference product of any of the NEW PRODUCTS.  In providing DEVELOPMENT
SERVICES herein, AAI may, but shall not be obligated to, consider appropriate
third-party technologies for use in one or more NEW PRODUCT, and AAI shall
promptly advise the Company on each occasion of its consideration of using such
technologies and the anticipated costs and benefits of the use of such
technologies.  AAI shall not acquire or license such third-party technology for
use in a NEW PRODUCT unless AAI and the Company mutually agree to the terms and
conditions of such acquisition or license, including AAI's reimbursement for
any AAI cost associated with the same.

request AAI, or other persons or entities engaged by or working under the
directions of AAI, to produce records, data and materials relating to NEW

         Section 2.8      EXCLUSIVITY; RIGHT OF FIRST REFUSAL.  AAI shall be
the Company's exclusive provider of DEVELOPMENT SERVICES for the INITIAL

reasonable




<PAGE>   10

DEVELOPMENT AGREEMENT
Page 10 of 26


investigation that the expense to the Company for services provided or to be
provided by AAI hereunder with respect to such NEW PRODUCT have or would
significantly exceed the price of reasonably comparable services available from
a reasonably comparable firm, the Company may retain any such other firm to
perform the services contemplated hereunder with respect to such NEW PRODUCT.
Except as permitted by the proviso of the foregoing sentence, the Company shall
not contract with any third party to obtain services to develop any product
that the Company wishes to design or develop, unless the Company shall have
first negotiated on an exclusive basis with AAI for a period of not less than
sixty (60) days as to a good faith proposal for the performance by AAI of
DEVELOPMENT SERVICES on terms and conditions substantially identical to those
to be provided hereunder.

         Section 2.9      PRIOR SERVICES.  Prior to the execution of this
Agreement, AAI has performed DEVELOPMENT SERVICES with respect to certain of
the INITIAL PRODUCTS at the Company's request.  AAI hereby transfers and
assigns to the Company all such intellectual property rights as the Company
would have obtained pursuant to this Agreement if all such services had been
performed hereunder.  The parties agree that they shall execute such further
agreements, documents and instruments necessary to effect such transfer.  In
addition, the Company shall promptly pay to AAI an amount equal to the amount
that would be chargeable by AAI hereunder if such services had been performed
pursuant to the terms hereof, except that the hourly rates for services
performed prior to March 1, 1995 shall be chargeable at the rates originally
agreed upon by AAI and the Company as set forth in Schedule 2.9 attached

provide DEVELOPMENT SERVICES hereunder for and on behalf of the COMPANY.
Notwithstanding the foregoing, the parties recognize that AAI shall have the
right to independently develop, without reference to any NEW PRODUCT SUBMISSION
PACKAGE, COMPANY TECHNICAL INFORMATION or COMPANY INVENTIONS, documents which
are substantially similar to the documents within a NEW PRODUCT SUBMISSION
PACKAGE for its own account or on behalf of third parties.

         The Company shall have full responsibility and authority for the
COMMERCIALIZATION of any NEW PRODUCT to or with third parties, and this
Agreement shall not create in the Company any continuing obligation to promote,
market, sell, license or otherwise exploit any NEW PRODUCT.  AAI shall not
promote, market, sell or otherwise seek to COMMERCIALIZE any NEW PRODUCT.
Nothing in this Agreement shall restrict AAI from developing competing
technologies or products for its own account or for and on behalf of third
parties, subject to the ownership and confidentiality provisions set forth in
this Article III and Article VIII, respectively, and the restriction on the
formulation of certain products that may compete with the NEW PRODUCTS as set
forth in Section 2.0.

         Neither party may publicly use any trademark, servicemark, trade name

         The parties hereto recognize that AAI may have to subcontract with
third party contractors for the performance of certain services agreed upon
hereunder.  AAI shall be permitted to do so provided AAI gives the Company
prior written notice of its intention to do so and the Company approves such

         Beginning December 1995 and in each subsequent December during the
         term of this Agreement, the parties will review the schedule of rates
         then in effect pursuant to this Agreement and negotiate in good faith
         any prospective adjustment to the rates to be charged hereunder;
         provided, however, that during the annual periods ending December 31,
         1997 and thereafter, the percentage increase in the hourly rates to be
         charged hereunder in any year from the hourly rates in effect for the
         immediately preceding year shall not exceed the greater of (i) the
         percentage increase between the same periods in the all-cities
         Consumer Price Index as published by the United States Bureau of Labor
         Statistics, or (ii) the percentage increase between the same periods
         in AAI's wage and employee benefit expenses for its employees

         furnish the Company such information as the Company may reasonably
         request to support any increase under the preceding clause (ii).

         The parties recognize that certain routine technical functions are
         charged according to standard fractional hourly units (e.g., 0.2
         hours) for administrative convenience.

                 (b)      TRAVEL AND OUT-OF-POCKET EXPENSES.  AAI anticipates
         that certain travel and out-of-pocket expenses will be incurred during
         the performance of its duties hereunder.  The Company agrees to pay
         for ordinary and necessary travel and other incidental expenses
         incurred in providing DEVELOPMENT SERVICES provided however that AAI
         shall not incur any such individual expense greater then Five Thousand
         Dollars ($5,000) without the Company's prior approval which shall not
         unreasonably be withheld.

                 (e)      SUBCONTRACTORS.  The Company agrees to pay AAI for
         approved subcontracted services at cost and the supervision, auditing,
         and coordination of such subcontractors at the hourly rates set forth
         in Section 5.1(a).

                 (f)      RATES AND CHARGES.  AAI represents, warrants and
         covenants that the hourly rates, facilities charges and material
         handling charges to be charged to the Company for services hereunder,
         as the same shall change from time to time, shall be reasonably within
         the range of rates normally charged to AAI's customers for whom AAI
         provides services comparable to those to be provided to the Company
         hereunder.

                 (g)      ACQUISITION OR LICENSE OF THIRD PARTY TECHNOLOGY.
         The Company agrees to pay any costs (including royalty obligations)
         AAI may sustain based on the acquisition or licensing of any
         third-party technology related to the DEVELOPMENT SERVICES as mutually
         agreed to pursuant to Article II hereof.

         Section 5.2      ANNUAL BUDGET.  Prior to January 1 of each calendar
year during the term of this Agreement, AAI agrees to use reasonable and
diligent efforts to prepare, and submit to the Company for review and approval,
an ANNUAL BUDGET establishing in reasonable detail the Company's estimated
monthly requirements of DEVELOPMENT SERVICES for the upcoming calendar year
based on approved SERVICE ESTIMATES.  Upon approval by the Company, the ANNUAL
BUDGET will be attached hereto and incorporated herein as EXHIBIT "A."  AAI
shall provide notice to the Company of any significant variance from the
current ANNUAL BUDGET.

                 (a)      MONTHLY PAYMENT.  On or before the first day of each
         month, AAI shall invoice the Company for budgeted service fees and
         expenses for that month as established in the then current approved
         ANNUAL BUDGET.  The invoiced amount will be due thirty days after
         receipt.  AAI shall apply these funds against amounts due and payable
         to AAI by the Company under the





<PAGE>   15

DEVELOPMENT AGREEMENT
Page 15 of 26


         terms and conditions of this Agreement.  AAI shall maintain accurate
         accounting records of the Company's monthly payments and deductions
         therefrom for services rendered and expenses incurred.

                 (b)      RECONCILIATION OF MONTHLY PAYMENTS AND CHARGES.
         Monthly payments shall be reconciled against AAI's cumulative service
         fees and expenses semi-annually on each July 15 and January 15 during
         the term for the preceding months of this Agreement.  In the event a
         reconciliation results in a credit or debit balance to the Company's
         account, it shall be handled as follows:

                          (i)     Credit Balances.  In the event the Company's
                 cumulative monthly payment to AAI exceeds the cumulative
                 service fees and expenses accrued through the date of
                 reconciliation,  AAI shall issue a credit to the Company in
                 the amount of the overpayment which shall be applied to the
                 Company's succeeding monthly payment obligations pursuant to
                 the ANNUAL BUDGET until such credit is exhausted.  In the
                 event that there are no remaining monthly payment obligations
                 to be performed by the Company, AAI shall pay the Company the
                 credit balance immediately upon demand by the Company.

                          (ii)    Debit Balances.  In the event the Company's
                 cumulative monthly payments to AAI are less than the
                 cumulative service fees and expenses accrued through the date
                 of reconciliation, the Company shall pay AAI the debit balance
                 within thirty (30) days of the Company's receipt of an invoice
                 for such underpayment amount.

                          (iii)   Should any part of the reconciliation be in
                 dispute, the Company and AAI, as the case may be, covenants to
                 pay or credit the undisputed amount according to the terms and
                 conditions described herein while said dispute is being
                 resolved.

         Section 5.3      AUDIT RIGHTS.  The Company shall have the right, upon
reasonable notice and at its own expense, during AAI's performance of
DEVELOPMENT SERVICES, and for a period of three (3) years thereafter, to
conduct an audit of services fees and expenses charged to the Company for such
services.  The audit shall be conducted by a certified public accountant
selected by the Company.  AAI shall keep a complete and accurate account of
expenses charged to the Company and shall allow the examination of such records
by the selected accountant during regular business hours.  Such audits shall be
performed no more frequently than annually.

                         LIABILITY AND INDEMNIFICATION

         Section 6.1      LIABILITY OF AAI FOR DEVELOPMENT SERVICES.  The
parties agree that AAI's liability to the Company for claims arising from or
relating to the DEVELOPMENT SERVICES with respect to each single NEW PRODUCT
dosage form under this Agreement shall be limited to the amount of compensation
which AAI has received from the Company for DEVELOPMENT SERVICES rendered
hereunder relating to that particular NEW PRODUCT dosage form.  AAI shall not
be liable to the Company for injuries sustained by third parties;  special,
indirect or consequential damages; or any cost associated with a NEW PRODUCT's
recall.  Any test results, reports or analysis provided by AAI shall only be
for consideration and use by the Company in the design and development of the
NEW PRODUCTS, and AAI shall not be responsible for the adoption, use,
implementation or results of such test results, reports or analysis.

         Section 6.2      INDEMNIFICATION OF AAI.  The Company shall indemnify
and hold harmless AAI, its directors, officers, shareholders, agents, employees
and affiliates from any loss, expense and liability, including reasonable
attorney's fees arising from or in connection with the use or application by
the Company or any third party of any formulas, test results, analysis or other
information furnished by AAI hereunder or with the distribution or sale of any
NEW PRODUCT or CLINICAL SUPPLIES developed under this Agreement; provided,
however, that the Company shall not be obligated to provide such
indemnification if, when and to the extent that it is finally judicially
determined that the loss, expense or liability results from the gross
negligence or willful misconduct of AAI.  Each person or entity seeking
indemnification hereunder shall promptly notify the Company of any loss,
expense or liability for which the Company may be liable hereunder and shall
permit the Company a reasonable opportunity to cure any underlying problem to
mitigate actual or potential damages, and to participate in, or assume the
defense of, any third-party claim or action.  In the event that the Company
chooses to assume the defense of any third-party claim or action, the Company
shall provide the indemnified persons with notice of the progress of such
defense.  The Company further agrees that it will not, without prior written
consent of the indemnified persons, which consent shall not be unreasonably
withheld or delayed, settle, compromise or consent to the entry of any judgment
or award in any pending or threatened claim, action, suit or proceeding in
respect of which indemnification may be sought hereunder.  The rights of AAI
hereunder shall be an addition to any other rights that AAI or any other
indemnified

person may have, at law or otherwise, including, but not limited to, any right
to contribution.

         Section 6.3      SURVIVAL.  The covenants and obligations of
indemnification set forth herein shall survive the expiration or termination of
this Agreement.

         Section 6.4      INSURANCE.

                 (a)      At AAI's written request prior to commencing CLINICAL
         STUDIES, the Company agrees that it will acquire and maintain clinical
         research insurance coverage reasonably satisfactory to AAI, but not
         less than $10,000,000 per occurrence, which indemnifies AAI for any
         and all liability arising out of defects in the design, marketing,
         promotion, sale, delivery, resale or use of any NEW PRODUCT.

                 (b)      At AAI's written request prior to commencing
         COMMERCIALIZATION of a NEW PRODUCT, the Company agrees that it will
         acquire and maintain product liability insurance coverage reasonably

manner herein provided, this Agreement shall continue for a period of eight (8)
years.

         Section 7.2      TERMINATION.  The rights and obligations of the
Company and AAI under this Agreement can be terminated in accordance with
Section 7.1 or:

                 (a)      upon the written consent of both the Company and AAI;

                 (b)      by either party, if the other applies for, consents
         to or acquiesces in the appointment of a trustee or a receiver for
         itself or its property, or in the absence of such application, consent
         or acquiescence, a trustee or receiver is appointed for the other
         party or for the property of the other party or if any bankruptcy,
         reorganization or other proceeding under any bankruptcy or insolvency

                 (c)      by either party, upon the failure of the other to
         comply with any of the material provisions of this Agreement provided,
         however, no such right of termination shall be available under this
         Section 7.2(c) unless the aggrieved party has first served upon the
         non-complying party written notice of such non-compliance and such
         non-compliance remains uncorrected for a period of sixty (60) days
         after receipt of such notice; or

                 (d)      by AAI, upon AAI's determination in its reasonable
         judgment that its performance hereunder or any of its affiliates,
         whether considered alone or in combination with other activities and
         services provided by AAI or its affiliates, conflicts with or violates
         (i) any statute, rule, regulation or decree of any court,
         administrative agency or government body (including, without
         limitation, the National Institutes of Health) to which it may be
         subject, or (ii) ethical standards or principles applicable to the
         pharmaceutical industry.

appropriate adjustments to the ANNUAL BUDGET and to reduce the Company's
monthly payment obligations thereunder.  Except for termination by AAI pursuant
to Section 7.2(b) or (c), the license granted by AAI pursuant to Section 3.1
shall survive the expiration or termination of this Agreement.

         Section 8.1      NONDISCLOSURE.  The following provided by one party
to this Agreement (the "Disclosing Party") and received by the other party to
this Agreement (the "Receiving Party") shall be deemed confidential:

                 (i)      All confidential and proprietary business or

         Such confidential information shall be safeguarded by the Receiving
Party, shall not be disclosed to third parties or used for any purpose other
than as permitted herein and shall be made available only to the Receiving
Party employees, subcontractors or consultants who have a need to know for the
purposes specified under this Agreement.  These obligations of confidentiality
shall apply during the term of this Agreement, and shall survive the
termination of this Agreement, but such obligations shall not apply to any
information to the extent that such information:

                 (a)      is or hereafter becomes generally available to the
         public other than by reason of any default with respect to a
         confidentiality obligation under this Agreement;

                 (b)      is disclosed to the Receiving Party by a third party
         who is not in default of any confidentiality obligation to the
         Disclosing Party; or

                 (c)      is conceived by the Receiving Party independent of
         the DEVELOPMENT SERVICES being provided pursuant to this Agreement.

         Notwithstanding the restrictions on confidential information set forth
above, either party may use or disclose confidential information to the extent
that such confidential information:

                 (a)      is submitted to governmental agencies to facilitate a
         NEW PRODUCT's FDA APPROVAL hereunder or to support the marketing of an
         approved NEW PRODUCT provided that reasonable measures shall be taken
         to assure confidential treatment of such information;

                 (b)      is provided to third party subcontractors under
         appropriate terms and conditions including confidentiality provisions
         at least as stringent as those in this Agreement;

                 (c)      is required to be disclosed in compliance with
         applicable laws or regulations in connection with the manufacture or
         sale of a NEW PRODUCT; provided that the Receiving Party provides the
         Disclosing Party with notice of intended disclosure as far in advance
         as possible under the circumstances; or

                 (d)      is otherwise required to be disclosed in compliance
         with applicable laws, regulations or policies of the FDA or any other
         applicable governmental agency or authority or order by a court or
         other regulatory body having competent jurisdiction; provided that the
         Receiving Party provides the





<PAGE>   21

DEVELOPMENT AGREEMENT
Page 21 of 26


         Disclosing Party with notice of intended disclosure as far in advance
         as possible under the circumstances.

Upon expiration or earlier termination of this Agreement and upon payment in
full under Article V and Section 7.2 hereto, but subject to Articles III and IV
hereof, the Receiving Party shall return to the Disclosing Party all records
and any compositions, articles, devices, equipment and other items which
disclose or embody all of the Disclosing Party's confidential information,
including all copies or specimens thereof, whether prepared by the Receiving
Party, any subcontractors or others, except for such records and other items
which the Receiving Party or such third-parties, as the case may be, are
required to retain in accordance with applicable law including FDA guidelines
or information subject to FDA review.  Notwithstanding the foregoing, the
Receiving Party may retain  copies of such records for archival purposes only.
The Receiving Party agrees that the provisions of this Article VIII are
necessary and reasonable to protect the Disclosing Party (or any other entity
which succeeds, in whole or in part, to the Disclosing Party) in the conduct of
its business.  The Receiving Party acknowledges that damages at law may be an
inadequate remedy for the breach of any of the covenants contained in this
Article VIII and, accordingly, in addition to any of the remedies which the
Disclosing Party would otherwise be entitled, the Disclosing Party shall be
entitled to seek injunctive relief for breach by the Receiving Party of any of
the provisions contained herein.
