                               PROSPECTUS SUMMARY
 
    THE FOLLOWING SUMMARY IS QUALIFIED IN ITS ENTIRETY BY THE MORE DETAILED
INFORMATION AND FINANCIAL STATEMENTS AND NOTES THERETO APPEARING ELSEWHERE IN
THIS PROSPECTUS. UNLESS OTHERWISE INDICATED, ALL REFERENCES HEREIN TO "AKORN" OR
THE "COMPANY" REFER TO AKORN, INC. AND ITS SUBSIDIARIES.
 
                                  THE COMPANY
 
    Akorn is a specialty pharmaceutical company that develops, manufactures and
markets ophthalmic and injectable sterile pharmaceutical products in the United
States. The Company sells more than 90 diagnostic and therapeutic pharmaceutical
products focused primarily on ophthalmology, anesthesia, antidotes and
rheumatology. The Company also markets ophthalmic surgical instruments and other
supplies and provides contract manufacturing for third parties. The Company is
one of a limited number of U.S. specialty pharmaceutical companies with sterile
manufacturing capabilities. Akorn believes that its sterile manufacturing
capabilities, combined with its ability to manufacture a variety of dosage forms
(solutions, suspensions and ointments), afford it a competitive advantage. Many
of the Company's ophthalmic pharmaceuticals are marketed under its
well-recognized "Akorn" label. For the twelve months ended June 30, 1998,
Akorn's net sales and net income were approximately $49.3 million and $3.8
million, respectively.
 
    While the $110 billion U.S. pharmaceutical market is dominated by large
multinational pharmaceutical companies that conduct substantial research and
development, significant sales are derived from specialty pharmaceutical
products. The Company believes that pricing and profit pressures are causing
major pharmaceutical companies to focus on developing new pharmaceuticals and
marketing existing proprietary products, while considering divestitures or
licensing of non-core products as a more effective means of realizing value from
such products. The Company defines specialty pharmaceutical products as those
products which share several, but not necessarily all, of the following
characteristics: (i) products which no longer fit the strategic focus of major
pharmaceutical companies; (ii) products with annual sales typically between $1
and $50 million; (iii) products which receive minimal promotion from major
pharmaceutical companies but which compete in promotion-sensitive markets; (iv)
products which have sales levels that are less likely to become targets of
pricing pressure from managed care or other third-party payors, or which have a
clear price advantage over alternative treatments; and (v) products which can
leverage the existing sales force, manufacturing operations and marketing
efforts of specialty pharmaceutical companies.
 
    Sterile pharmaceutical products consist of pharmaceuticals produced using
sterile manufacturing techniques, such as aseptic filling technologies and heat
sterilization. The manufacture of sterile pharmaceutical products, as compared
to the production of non-sterile products such as tablets, requires more
technologically sophisticated processes and personnel with technical expertise.
In 1997, the U.S. ophthalmic and injectable sterile pharmaceutical markets had
total U.S. sales of approximately $2.0 billion and $8.2 billion, respectively,
which represent increases of approximately 10.0% and 12.0%, respectively, from
1996.
 
    To capitalize on the trend of major pharmaceutical companies devoting less
resources to specialty pharmaceutical products, the Company focuses on sterile
specialty pharmaceutical products that generally face limited competition. The
Company's objective is to become a leading sterile specialty pharmaceutical
company. To achieve this objective, the Company seeks to: (i) pursue strategic
acquisitions of branded sterile specialty pharmaceutical products; (ii)
internally develop sterile specialty pharmaceutical products; (iii) leverage its
existing infrastructure and increase operating efficiencies; and (iv) expand its
sterile manufacturing and technical capabilities. As part of this strategy, the
Company is developing the capability to manufacture controlled-release and
lyophilized (freeze-dried) pharmaceuticals in order to expand the dosage forms
of its current products and pursue other markets.
 
                                       1
<PAGE>
    Since January 1, 1996, the Company has acquired or licensed 18 specialty
pharmaceutical products. In acquiring or licensing pharmaceutical products, the
Company targets products which complement its existing product lines and enable
it to leverage its existing manufacturing, marketing and distribution
capabilities. After acquiring or licensing a specialty pharmaceutical product,
the Company generally focuses on increasing the marketing and promotion of the
product and integrating it into the Company's existing product lines.
 
    The Company also develops pharmaceutical products internally. Since January
1, 1996, the Company has received approval for nine ANDAs and one NDA for
internally developed sterile pharmaceutical products. In connection with its
strategy to continue to internally develop sterile pharmaceutical products,
Akorn currently has ten ANDAs submitted to the FDA for new products. In
addition, over the next three years, the Company anticipates filing ANDAs for
more than ten additional sterile pharmaceutical products and NDAs for three
proprietary pharmaceutical products which are in various stages of development.

<PAGE>
                                  RISK FACTORS
 
    IN ADDITION TO THE OTHER INFORMATION IN THIS PROSPECTUS, THE FOLLOWING
FACTORS SHOULD BE CONSIDERED CAREFULLY IN EVALUATING AN INVESTMENT IN THE SHARES
OF COMMON STOCK OFFERED BY THIS PROSPECTUS.
 
GOVERNMENT REGULATION
 
    Virtually all aspects of the Company's business are regulated by federal and
state statutes and government agencies. The development, testing, manufacturing,
processing, quality, safety, efficacy, packaging, labeling, record-keeping,
distribution, storage and advertising of the Company's products, and disposal of
waste products arising from such activities, are subject to regulation by one or
more federal agencies, including the Food and Drug Administration ("FDA"), the
Drug Enforcement Agency ("DEA"), the Federal Trade Commission ("FTC"), the
Consumer Product Safety Commission, the Occupational Safety and Health
Administration ("OSHA") and the U.S. Environmental Protection Agency ("EPA").
These activities are also regulated by similar state and local agencies. Failure
to comply with applicable statutes and government regulations could have a
material adverse effect on the Company's business, financial condition and
results of operations.
 
    All pharmaceutical manufacturers, including the Company, are subject to
regulation by the FDA under the authority of the Federal Food, Drug, and
Cosmetic Act ("FDC Act"). Under the FDC Act, the federal government has
extensive administrative and judicial enforcement powers over the activities of
pharmaceutical manufacturers to ensure compliance with FDA regulations. Those
powers include, but are not limited to, the authority to initiate court action
to seize unapproved or non-complying products, to enjoin non-complying
activities, to halt manufacturing operations that are not in compliance with
current good manufacturing practices ("cGMP"), to recall products which present
a health risk, and to seek civil monetary and criminal penalties. Other
enforcement activities include refusal to approve product applications or the
withdrawal of previously approved applications. Any such enforcement activities,
including the restriction or prohibition on sales of products marketed by the
Company or the halting of manufacturing operations of the Company, could have a
material adverse effect on the Company's business, financial condition and
results of operations. In addition, product recalls may be issued at the
discretion of the Company, the FDA or other government agencies having
regulatory authority for pharmaceutical product sales. Recalls may occur due to
disputed labeling claims, manufacturing issues, quality defects or other
reasons. No assurance can be given that recalls of the Company's pharmaceutical
products will not occur in the future. Any product recall could have a material
adverse effect on the Company's business, financial condition and results of
operations.
 
    All "new drugs" must be the subject of an FDA-approved new drug application
("NDA") before they may be marketed in the United States. Certain prescription
drugs are not currently required to be the subject of an approved NDA but,
rather, may be marketed pursuant to an FDA regulatory enforcement policy
permitting continued marketing of those drugs until the FDA determines whether
they are safe and effective. All generic equivalents to previously approved
drugs or new dosage forms of existing drugs must be the subject of an
FDA-approved abbreviated new drug application ("ANDA") before they may be
marketed in the United States. The FDA has the authority to withdraw existing
NDA and ANDA approvals and to review the regulatory status of products marketed
under the enforcement policy. The FDA may require an approved NDA or ANDA for
any drug product marketed under the enforcement policy if new information
reveals questions about the drug's safety or effectiveness. All drugs must be
manufactured in conformity with cGMP and drugs subject to an approved NDA or
ANDA must be manufactured, processed, packaged, held, and labeled in accordance
with information contained in the NDA or ANDA.
 
    The Company and its third-party manufacturers are subject to periodic
inspection by the FDA to assure such compliance. The FDA imposes additional
stringent requirements on the manufacture of sterile pharmaceutical products to
ensure the sterilization processes and related control procedures consistently
produce a sterile product. Additional sterile manufacturing requirements include
the
 
                                       5
<PAGE>
submission for expert review of detailed documentation for sterilization process
validation in drug applications beyond those required for general manufacturing
process validation. Various sterilization process requirements are the subject
of detailed FDA guidelines, including requirements for the maintenance of
microbiological control and quality stability. Pharmaceutical products must be
distributed, sampled and promoted in accordance with FDA requirements. The FDA
also regulates drug labeling and the advertising of prescription drugs. The
Company believes its operating facilities and practices are in compliance with
applicable federal and state law. However, a finding by a governmental agency or
court that the Company is not in compliance could have a material adverse effect
on the Company's business, financial condition and results of operations.
 
    While the Company believes that all of its current pharmaceuticals are
lawfully marketed in the United States under current FDA enforcement policies or
have received the requisite agency approvals for manufacture and sale, such
marketing authority is subject to withdrawal by the FDA. In addition,
modifications or enhancements of approved products are in many circumstances
subject to additional FDA approvals which may or may not be granted and which
may be subject to a lengthy application process. Any change in the FDA's
enforcement policy or any decision by the FDA to require an approved NDA or ANDA
for a Company product not currently subject to the approved NDA or ANDA
requirements or any delay in the FDA approving an NDA or ANDA for a Company
product could have a material adverse effect on the Company's business,
financial condition and results of operations.
 
    A number of products marketed by the Company are "grandfathered" drugs which
are permitted to be manufactured and marketed without FDA-issued ANDAs or NDAs
on the basis of their having been marketed prior to enactment of relevant
sections of the FDC Act. The regulatory status of these products is subject to
change and/or challenge by the FDA, which could establish new standards and
limitations for manufacturing and marketing such products, or challenge the
evidence of prior manufacturing and marketing upon which grandfathering status
is based. The Company is not aware of any current efforts by the FDA to change
the status of any of its "grandfathered" products, but there can be no assurance
that such initiatives will not occur in the future. Any such change in the
status of the Company's "grandfathered" products could have a material adverse
effect on the Company's business, financial condition and results of operations.
 
    The Company also manufactures and sells drugs which are "controlled
substances" as defined in the federal Controlled Substances Act and similar
state laws, which establishes, among other things, certain licensing, security
and record keeping requirements administered by the DEA and similar state
agencies, as well as quotas for the manufacture, purchase and sale of controlled
substances. The DEA could limit or reduce the amount of controlled substances
which the Company is permitted to manufacture and market. The Company has not
experienced sanctions or fines for non-compliance with the foregoing
regulations, but no assurance can be given that any such sanctions or fines
would not have a material adverse effect on the Company's business, financial
condition and results of operations.
 
    The Company cannot determine what effect changes in regulations or statutes
or legal interpretation, when and if promulgated or enacted, may have on its
business in the future. Changes could, among other things, require changes to
manufacturing methods, expanded or different labeling, the recall, replacement
or discontinuation of certain products, additional record keeping and expanded
documentation of the properties of certain products and scientific
substantiation. Such changes or new legislation could have a material adverse
effect on the Company's business, financial condition and results of operations.
See "Business--Government Regulation."
 
DEPENDENCE ON ACQUISITION AND LICENSING OF PHARMACEUTICAL PRODUCTS
 
    Until the Company develops and introduces a sufficient number of its own
pharmaceutical products, it must rely upon the availability for purchase or
licensing of pharmaceutical product lines of other pharmaceutical or
biotechnology companies. Other companies, including those with substantially
 
                                       6
<PAGE>
greater financial, marketing and other resources, compete with the Company for
the right to acquire or license such products. The Company's success in
executing this strategy depends, in part, on its ability to identify potential
products that meet the Company's criteria, including possessing a recognizable
brand name or being complementary to the Company's existing product lines. See
"Business--Strategy." There can be no assurance that the Company will have
success in identifying potential product acquisitions or licensing opportunities
or that, if identified, it will complete such product acquisitions or obtain
such licenses on acceptable terms or that it will successfully integrate any
acquired or licensed products into its existing product lines. The inability to
complete acquisitions of, or obtain licenses for, pharmaceutical products could
have a material adverse effect on the Company's business, financial condition
and results of operations. Furthermore, there can be no assurance that the
Company, once it has obtained rights to a pharmaceutical product and committed
to payment terms, will be able to generate sales sufficient to create a profit
or otherwise avoid a loss. Any inability to generate such sufficient sales or
any subsequent reduction of sales could have a material adverse effect on the
Company's business, financial condition and result of operations. See
"Business--Strategy" and "--Product Acquisitions."
 
DEPENDENCE ON DEVELOPMENT OF PHARMACEUTICAL PRODUCTS AND MANUFACTURING
  CAPABILITIES
 
    The Company's strategy for growth is dependent upon its ability to develop
products that can be promoted through existing marketing and distribution
channels and, when appropriate, the enhancement of such marketing and
distribution channels. The Company currently has ten ANDAs submitted to the FDA
for new sterile pharmaceutical products. In addition, over the next three years,
the Company currently anticipates filing ANDAs for more than ten additional
pharmaceutical products and NDAs for three proprietary pharmaceutical products
which are in various stages of development. The Company may not meet its
anticipated time schedule for the filing of ANDAs and NDAs or may decide not to
pursue ANDAs or NDAs that it has submitted or anticipates submitting. The
internal development of new pharmaceutical products by the Company is dependent
upon the research and development capabilities of the Company's personnel and
its infrastructure. There can be no assurance that the Company will successfully
develop new pharmaceutical products or, if developed, successfully integrate new
products into its existing product lines. In addition, there can be no assurance
that the Company will receive all necessary approvals from the FDA or that such
approvals will not involve delays which adversely affect the marketing and sale
of the Company's products. The Company's failure to develop new products or
receive FDA approval of new or previously filed ANDAs or NDAs, could have a
material adverse effect on the Company's business, financial condition and
results of operations. Another part of the Company's growth strategy is to
develop the capability to manufacture controlled-release ophthalmic
pharmaceutical products and lyophilized (freeze-dried) pharmaceutical products.
While the Company has devoted resources to developing these capabilities, it may
not be successful in developing these capabilities, or the Company may not
realize the anticipated benefits from developing these capabilities. See
"Business--Strategy."
 
GENERIC SUBSTITUTION
 
    The Company's branded pharmaceutical products are subject to competition
from generic equivalents and alternative therapies. Generic pharmaceuticals are
the chemical and therapeutic equivalents of brand-name pharmaceuticals and
represent an increasing proportion of pharmaceuticals dispensed in the United
States. There is no proprietary protection for most of the branded
pharmaceutical products sold by the Company and generic and other substitutes
for most of its branded pharmaceutical products are sold by other pharmaceutical
companies. In addition, governmental and cost-containment pressures regarding
the dispensing of generic equivalents will likely result in generic substitution
and competition generally for the Company's branded pharmaceutical products.
Although the Company attempts to mitigate the effect of this substitution
through, among other things, creation of strong brand-name recognition and
product-line extensions for its branded pharmaceutical products, there can be no
assurance that the Company will be successful in these efforts. Increased
competition in
 
                                       7
<PAGE>
the sale of generic pharmaceutical products could have a material adverse effect
on the Company's business, financial condition and results of operations. See
"--Competition; Uncertainty of Technological Change" and
"Business--Competition." Generic substitution is regulated by the federal and
state governments, as is reimbursement for generic drug dispensing. There can be
no assurance that substitution will be permitted for newly-approved generic
drugs or that such products will be subject to government reimbursement.
 
DEPENDENCE ON GENERIC AND OFF-PATENT PHARMACEUTICAL PRODUCTS
 
    For the six months ended June 30, 1998, the Company derived 49.8% of its net
sales from the sale of generic pharmaceutical products. The success of the
Company depends, in part, on its ability to anticipate which branded
pharmaceuticals are about to come off patent and thus permit the Company to
develop, manufacture and market equivalent generic pharmaceutical products.
Generic pharmaceuticals must meet the same quality standards as branded
pharmaceuticals, even though these equivalent pharmaceuticals are sold at prices
which are significantly lower than that of branded pharmaceuticals. In addition,
generic products that third parties develop may render the Company's generic
products noncompetitive or obsolete. Although the Company has successfully
brought generic pharmaceutical products to market in a timely manner in the
past, there can be no assurance that the Company will be able to consistently
bring these products to market quickly and efficiently in the future. An
increase in competition in the sale of generic pharmaceutical products or the
Company's failure to bring such products to market before its competitors could
have a material adverse effect on the Company's business, financial condition
and results of operations. See "Business--Strategy."
 
COMPETITION; UNCERTAINTY OF TECHNOLOGICAL CHANGE
 
    The Company competes with other pharmaceutical companies, including major
pharmaceutical companies with financial resources substantially greater than
those of the Company, in acquiring, developing, manufacturing and marketing
pharmaceutical products. The selling prices of pharmaceutical products typically
decline as competition increases. Further, other products now in use, under
development or acquired by other pharmaceutical companies, may be more effective
or offered at lower prices than the Company's current or future products. The
industry is characterized by rapid technological change which may render the
Company's products obsolete, and competitors may develop their products more
rapidly than the Company. Competitors may also be able to complete the
regulatory process sooner, and therefore, may begin to market their products in
advance of the Company's products. The Company believes that competition in
sales of its products is based primarily on price, service, availability and
product efficacy. There can be no assurance that: (i) the Company will be able
to acquire or develop commercially attractive pharmaceutical products; (ii)
additional competitors will not enter the market; or (iii) competition from
other pharmaceutical companies will not have a material adverse effect on the
Company's business, financial condition and results of operations. See
"--Generic Substitution" and "Business--Competition."
 
DEPENDENCE ON SUPPLY OF RAW MATERIALS AND COMPONENTS
 
    The Company requires a supply of quality raw materials and components to
manufacture and package pharmaceutical products for itself and for third parties
with which it has contracted. The principal components of the Company's products
are active and inactive pharmaceutical ingredients and certain packaging
materials. Many of these components are available from only a single source and,
in many of the Company's ANDAs and NDAs, only one supplier of raw materials has
been identified. Because FDA approval of drugs requires manufacturers to specify
their proposed suppliers of active ingredients and certain packaging materials
in their applications, FDA approval of any new supplier would be required if
active ingredients or such packaging materials were no longer available from the
specified supplier. The qualification of a new supplier could delay the
Company's development and
 
                                       8

marketing efforts. If for any reason the Company is unable to obtain sufficient
quantities of any of the raw materials or components required to produce and
package its products, it may not be able to manufacture its products as planned,
which could have a material adverse effect on the Company's business, financial
condition and results of operations.
 
DEPENDENCE ON THIRD-PARTY MANUFACTURERS
 
    For the six months ended June 30, 1998, the Company derived 51.1% of its net
sales from the sale of products manufactured by third parties. There can be no
assurance that the Company's dependence on third parties for the manufacture of
such products will not adversely affect the Company's profit margins or its
ability to develop and deliver its products on a timely and competitive basis.
If for any reason the Company is unable to obtain or retain third-party
manufacturers on commercially acceptable terms, it may not be able to distribute
its products a planned. No assurance can be made that the manufacturers utilized
by the Company will be able to provide the Company with sufficient quantities of
its products or that the products supplied to the Company will meet the
Company's specifications. Any delays or difficulties with third-party
manufacturers could adversely affect the marketing and distribution of certain
of the Company's products, which could have a material adverse effect on the
Company's business, financial condition and results of operations.
 
PRODUCT LIABILITY
 
    The Company faces exposure to product liability claims in the event that the
use of its technologies or products or those it licenses from third parties is
alleged to have resulted in adverse effects in users thereof. Receipt of
regulatory approval for commercial sale of such products does not mitigate such
product liability risks. While the Company has taken, and will continue to take,
what it believes are appropriate precautions, there can be no assurance that it
will avoid significant product liability exposure. In addition, future product
labeling may include disclosure of additional adverse effects, precautions and
contraindications, which may adversely impact sales of such products. The
Company currently has product liability insurance in the amount of $10.0 million
for aggregate annual claims with a $25,000 deductible per incident and a
$150,000 aggregate annual deductible. However, there can be no assurance that
its insurance coverage will be sufficient to cover fully potential claims.
Additionally, there can be no assurance that adequate insurance coverage will be
available in the future at acceptable costs, if at all, or that a product
liability claim would not have a material adverse effect on the Company's
business, financial condition and results of operations.
 
NEED TO ATTRACT AND RETAIN KEY PERSONNEL IN HIGHLY COMPETITIVE MARKETPLACE
 
    The Company's performance depends, to a large extent, on the continued
service of its key research and development personnel, other technical
employees, managers and sales personnel and its ability to continue to attract
and retain such personnel. Competition for such personnel is intense,
particularly for highly motivated and experienced research and development and
other technical personnel. The Company is facing increasing competition from
companies with greater financial resources for such personnel. There can be no
assurance that the Company will be able to attract and retain sufficient numbers
of highly-skilled personnel in the future, and the inability to do so could have
a material adverse effect on the Company's business, operating results and
financial condition. See "Business-- Competition" and "--Employees."
 
DEPENDENCE ON KEY EXECUTIVE OFFICERS
 
    The Company's success will depend, in part, on its ability to retain its key
executive officers. The loss of one or more of the Company's key executive
officers could have a material adverse effect on the Company's business,
financial condition and results of operations. See "Management."

QUARTERLY FLUCTUATION OF RESULTS; POSSIBLE VOLATILITY OF STOCK PRICE
 
    The Company's results of operations may vary from quarter to quarter due to
a variety of factors including the timing of acquisitions, development and sales
of branded pharmaceutical products, expenditures incurred to acquire and promote
additional pharmaceutical products, changes in the Company's customer base, a
customer's termination of a substantial account, the availability and cost of
raw materials, interruptions in supply by third-party manufacturers, the
introduction of new products or technological innovations by the Company's
competitors, delays in obtaining government approvals, including FDA approval of
NDAs or ANDAs for Company products, loss of key personnel, the mix of products
sold by the Company, changes in sales and marketing expenditures, competitive
pricing pressures and general economic and industry conditions which affect
customer demand. There can be no assurance that the Company will be successful
in maintaining or improving its profitability or avoiding losses in any future
period. Such fluctuations may result in volatility in the price of the Common
Stock. Due to the foregoing factors, it is possible that in future quarters the
Company's operating results will be below the expectations of investors or
securities analysts. Such an event could adversely affect the market price of
the Common Stock. In the past, following periods of volatility in the market
price of their securities, companies have become defendants in securities class
action litigation. Any such litigation initiated against the Company could
result in substantial costs and a diversion of management's attention and
resources, which could have a material adverse effect on the Company's business,
financial condition and results of operations. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations--Summary of Results of
Operations by Quarter."
 
PATENTS AND PROPRIETARY RIGHTS
 
    The patent position of competitors in the pharmaceutical industry generally
is highly uncertain, involves complex legal and factual questions, and is the
subject of much litigation. There can be no assurance that any patent
applications relating to the Company's potential products or processes will
result in patents being issued, or that the resulting patents, if any, will
provide protection against competitors who: (i) successfully challenge the
Company's patents; (ii) obtain patents that may have an adverse effect on the
Company's ability to conduct business; or (iii) are able to circumvent the
Company's patent position. It is possible that other parties have conducted or
are conducting research and could make discoveries of pharmaceutical
formulations or processes that would precede any discoveries made by the
Company, which could prevent the Company from obtaining patent protection for
these discoveries or marketing products developed therefrom. Consequently, there
can be no assurance that others will not independently develop pharmaceutical
products similar to or obsoleting those that the Company is planning to develop,
or duplicate any of the Company's products. The inability of the Company to
obtain patents for its products and processes or the ability of competitors to
circumvent or obsolete the Company's patents could have a material adverse
effect on the Company's business, financial condition and results of operations.
See "Business--Patents and Proprietary Rights."
 
RELATIONSHIPS WITH OTHER ENTITIES; CONFLICTS OF INTEREST
 
    Dr. John N. Kapoor, Ph.D., the Company's Chairman of the Board and Chief
Executive Officer, is affiliated with EJ Financial Enterprises, Inc., a health
care investment firm ("EJ Financial"). See "Certain Relationships and Related
Transactions." EJ Financial is involved in the management of health care
companies in various fields, and Dr. Kapoor is involved in various capacities
with the management and operation of these companies. The John N. Kapoor Trust,
the beneficiary of which is Dr. Kapoor, is a principal shareholder of each of
these companies. As a result, Dr. Kapoor devotes approximately two days per week
to the business of the Company. Although such companies do not currently compete
directly with the Company, certain companies with which EJ Financial is involved
are in the pharmaceutical business. Discoveries made by one or more of these
companies could render the Company's products
 
                                       10
<PAGE>
less competitive or obsolete. Potential conflicts of interest could have a
material adverse effect on the Company's business, financial condition and
results of operations. See "Management."
 
LITIGATION INVOLVING THE COMPANY'S CHAIRMAN
 
    Dr. Kapoor was previously the Chairman and President of Lyphomed, Inc., a
manufacturer of injectable pharmaceuticals ("Lyphomed"). Fujisawa Pharmaceutical
Co. Ltd. ("Fujisawa") was a major stockholder of Lyphomed from the mid-1980s
until 1990, at which time Fujisawa completed a tender offer for the remaining
shares of Lyphomed, including the shares held by Dr. Kapoor. Prior to and
following the tender offer by Fujisawa, Lyphomed experienced regulatory
difficulties with the FDA relating to the manufacturing and laboratory practices
involving certain generic pharmaceutical products. In 1991, the FDA investigated
and issued a Form 483 citing differences between the Company's generic drug
applications and underlying raw data. Lyphomed also experienced, following the
tender offer, declining results of operations. Fujisawa filed suit in federal
district court in Illinois against Dr. Kapoor alleging securities fraud,
racketeering, and other federal and state law claims relating to the purchase of
Lyphomed. In addition to substantial monetary relief, Fujisawa also sought the
imposition of a constructive trust on the assets of Dr. Kapoor, including the
shares of the Common Stock, representing approximately 23.6% of the Common
Stock, beneficially owned by Dr. Kapoor. The district court dismissed Fujisawa's
federal claims against Dr. Kapoor and Fujisawa appealed. The appellate court
affirmed the district court's dismissal of the securities fraud claim on the
grounds that the statute of limitations had run, but overturned the district
court's dismissal of the racketeering claims and remanded the matter, including
the state law claims, to the trial court. Dr. Kapoor has denied Fujisawa's
allegations and continues to defend the suit. Although the Company is not a
party to these suits, these proceedings against Dr. Kapoor, the imposition of a
constructive trust on the shares of the Common Stock held by Dr. Kapoor or
heightened FDA scrutiny as a result of these proceedings could have a material
adverse effect on the Company.
 
SHARES ELIGIBLE FOR FUTURE SALE
 
    Immediately after completion of this Offering, the Company will have
22,952,063 shares of Common Stock outstanding. Of these shares, 21,952,063
shares (including the 5,540,000 shares sold pursuant to this Offering) will be
freely tradable without restriction or further registration under the Securities
Act other than those shares held by "affiliates" of the Company. The remaining
1,000,000 shares will become eligible for resale in December 1998, subject to
the limitations set forth under Rule 144 ("Rule 144") under the Securities Act
of 1933, as amended (the "Securities Act"), as applicable. The Company, together
with its executive officers and directors (holding in the aggregate
approximately 5,064,793 shares of Common Stock after completion of this
Offering), will enter into agreements not to, subject to certain exceptions,
register the sale of, sell, offer to sell, contract to sell, grant any option to
purchase or otherwise dispose of, directly or indirectly, any shares of Common
Stock or any securities convertible into or exercisable or exchangeable for
Common Stock, other than the shares offered hereby, for a period ranging from 90
to 180 days after the date of this Prospectus, without the prior written consent
of BT Alex. Brown Incorporated. However, BT Alex. Brown Incorporated may, in its
discretion, waive the foregoing restrictions in whole or in part, with or
without a public announcement of such action. The sale of a substantial number
of shares of Common Stock, or the perception that such sales could occur, could
adversely affect prevailing market prices for the Common Stock. In addition, any
such sale or such perception could make it more difficult for the Company to
sell equity securities or equity-related securities in the future at a time and
price that the Company deems appropriate. See "Shares Eligible for Future Sale."

RISKS RELATED TO YEAR 2000 ISSUES
 
    The "Year 2000" issue concerns the potential exposures related to the
automated generation of business and financial misinformation resulting from the
application of computer programs which have been written using two digits,
rather than four, to define the applicable year of business transactions
resulting in the year 2000 being recognized as the year 1900 by the computer
program. The Company utilizes commercially available software to store and
process its business information transactions. The Company has already begun to
modify its computer systems to be Year 2000-compliant by upgrading the server
software of its injectable business and completing the installations of Year
2000-compliant financial software in the ophthalmic business. The Company
expects to be fully Year 2000-compliant by the end of 1998. In addition, the
Company has communicated with others with whom it does significant business to
determine their Year 2000-compliance readiness and the extent to which the
Company is vulnerable to any third-party Year 2000 issues. Failure of the
Company or its significant suppliers or customers to address adequately the Year
2000 issue could have a material adverse effect on the Company's business,
financial condition and results of operations. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations--Year 2000 Issue."

                                  THE COMPANY
 
    The Company is a Louisiana corporation founded in 1971 in Abita Springs,
Louisiana. In January 1992, the Company acquired Taylor Pharmacal Company, a
manufacturer of specialty injectable pharmaceutical products ("Taylor
Pharmaceuticals"). In June 1996, the Company acquired Pasadena Research
Laboratories, Inc., a distributor and marketer of injectable products ("PRL").
In July 1998, the Company acquired assets of Advanced Remedies, Inc., used in
the manufacture of sterile ophthalmic and injectable pharmaceutical products
("ARI"). In 1997, the Company moved its principal executive offices to 100
Tri-State International, Suite 100, Lincolnshire, Illinois 60069-4404. The
Company's telephone number is (847) 236-3800. The Company anticipates moving its
principal executive offices to 2500 Millbrook Drive, Buffalo Grove, Illinois
60089 in September 1998.
 
                                USE OF PROCEEDS
 
    The net proceeds to the Company from the sale of the 5,000,000 shares of
Common Stock offered by the Company, after deducting discounts and commissions
and estimated offering expenses payable by the Company, are estimated to be
$29.4 million ($34.4 million if the Underwriters' over-allotment option is
exercised in full), based upon an assumed offering price of $6.41 per share.
 
    The Company intends to use such net proceeds: (i) to repay approximately
$14.8 million of indebtedness under the Company's revolving credit facility;
(ii) for the acquisition and development of additional ophthalmic and injectable
pharmaceutical products; (iii) for expansion of manufacturing facilities; and
(iv) for working capital and general corporate purposes. The indebtedness under
the Company's revolving credit facility accrues at an annual rate equal to the
Federal Funds Rate plus an applicable margin. The rate on this indebtedness
approximated 7.0% as of June 30, 1998. The revolving credit facility matures on
December 20, 1999.
 
    The Company will not receive any proceeds from the sale of Common Stock by
the Selling Stockholders. See "Principal and Selling Stockholders."
 
                                DIVIDEND POLICY
 
    The Company has not paid cash dividends on the Common Stock since 1991 and
does not anticipate paying any cash dividends in the foreseeable future.
Instead, the Company anticipates that it will retain all of its earnings for the
continued operation and expansion of its business for the foreseeable future. In
addition, the terms of the Company's revolving credit facility prohibit it from
paying dividends or making other payments with respect to its Common Stock
without bank consent. Any future payment of dividends will depend upon the
Company's future operations and earnings, capital requirements and surplus,
general financial condition, contractual restrictions and such other factors as
the Board of Directors may deem relevant.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
    THE FOLLOWING DISCUSSION SHOULD BE READ IN CONJUNCTION WITH THE CONSOLIDATED
FINANCIAL STATEMENTS AND NOTES THERETO INCLUDED ELSEWHERE IN THIS PROSPECTUS.
SEE "RISK FACTORS" FOR TRENDS AND UNCERTAINTIES KNOWN TO THE COMPANY THAT COULD
CAUSE REPORTED FINANCIAL INFORMATION TO DIFFER MATERIALLY FROM FUTURE RESULTS.
 
OVERVIEW
 
    Akorn is a speciality pharmaceutical company that develops, manufactures and
markets ophthalmic and injectable sterile pharmaceutical products in the United
States. The Company sells more than 90 diagnostic and therapeutic pharmaceutical
products focused primarily on ophthalmology, anesthesia, antidotes and
rheumatology. The Company sells branded and generic pharmaceuticals, as well as
ophthalmic surgical instruments and other supplies, to hospitals, clinics, group
purchasing organizations, ophthalmalogists, optometrists and other specialty
physicians. The Company also provides contract manufacturing of injectable
pharmaceuticals for pharmaceutical and biotechnology companies.
 
    For the six-month period ended June 30, 1998, 53.1% of the Company's net
sales were derived from the sale of ophthalmic products and 46.9% were from the
sale of injectable products, including contract manufacturing for third parties.
For the six-month period ended June 30, 1998, 49.8% of the Company's net sales
were from the sale of generic pharmaceuticals, 30.9% were from the sale of
branded pharmaceuticals, 14.4% were from its contract manufacturing operations
and 4.9% were from the sale of ophthalmic surgical instruments and other
supplies. In the pharmaceutical industry, prices and margins for branded
pharmaceuticals are generally significantly higher than those for generic
pharmaceuticals. However, most of the branded pharmaceuticals sold by the
Company face competition from generic and other substitutes so these differences
are not as great for pharmaceutical products sold by the Company. For the
six-month period ended June 30, 1998, no single pharmaceutical product accounted
for more than 10.0% of the Company's net sales and only two of these products
accounted for more than 5.0% of the Company's net sales. Effective July 1, 1996,
the Company changed its fiscal year from June 30 to December 31.
 
  CHARGEBACKS
 
    Most of the Company's products sold to group-purchasing organization members
are distributed through wholesalers. The Company bills the wholesaler at the
Company's list price and reserves the estimated difference between list and
contract price. This reserve is carried as a reduction of accounts receivable.
The Company regularly evaluates the reserve balance against actual chargebacks
processed by wholesalers.
 
  CORPORATE ACQUISITIONS
 
    In January 1992, the Company acquired Taylor Pharmaceuticals in a
pooling-of-interests transaction valued at approximately $4.0 million. Taylor
Pharmaceuticals was a privately-held contract manufacturer of sterile
pharmaceuticals. The acquisition enabled the Company to increase its margins and
limit supply disruptions by internally manufacturing many of the ophthalmic
pharmaceuticals which it previously obtained from third-party manufacturers. The
acquisition also allowed the Company to diversify its revenues by contract
manufacturing injectable pharmaceuticals for third parties.
 
    In June 1996, the Company acquired PRL in a pooling-of-interests transaction
valued at approximately $3.8 million. PRL was a privately-held marketer of
sterile injectable pharmaceuticals primarily focused on antidotes and
rheumatology. The acquisition of PRL enabled the Company to expand the customer
base for its injectable pharmaceutical products.
 
                                       17
<PAGE>
    In July 1998, the Company acquired the assets, including four approved ANDAs
and five submitted ANDAs, of ARI from Sidmak, Inc. for approximately $4.0
million. The acquisition was paid for in cash and financed by the Company's
existing $25.0 million revolving credit facility. The ARI acquisition provides
the Company with capability to manufacture ophthalmic ointments and suspensions
and will allow the Company to reduce further its dependence on third-party
manufacturers.
 
  PRODUCT ACQUISITIONS, LICENSING AND DEVELOPMENT
 
    Since January 1, 1996, the Company has acquired or licensed 18 specialty
pharmaceutical products. The Company generally seeks to acquire or license
specialty pharmaceutical products which complement its existing product lines
and allow it to leverage existing manufacturing and marketing capabilities.
Since January 1, 1996, the Company has received FDA approval for nine ANDAs and
one NDA. As of June 30, 1998, the Company had ten ANDAs submitted to the FDA for
new products and had three NDAs and more than ten ANDAs in various stages of
development. See "Risk Factors Dependence on Development of Pharmaceutical
Products and Manufacturing Capabilities" and "--Dependence on Acquisition and
Licensing of Pharmaceutical Products."
 
  SEASONALITY
 
    While there is seasonal demand for some of the Company's pharmaceutical
products, seasonal fluctuations in demand have not historically had a material
effect on the Company's consolidated quarterly revenues.

</TABLE>
 
SIX MONTHS ENDED JUNE 30, 1998 AND 1997
 
    NET SALES.  Consolidated net sales increased 36.7% in the six-month period
ended June 30, 1998 compared to the same period in 1997. Ophthalmic-related
sales increased 18.8%, reflecting new product introductions and acquisitions as
well as growth in the base business. Injectable-related sales increased 64.8%
compared to the same period in 1997 due primarily to product acquisitions and
increased contract manufacturing activity.
 
    GROSS PROFIT.  Consolidated gross profit increased 59.0% during the period,
with gross margins increasing from 43.8% to 50.9%, reflecting product
acquistions.
 
                                       18
<PAGE>
    SELLING, GENERAL AND ADMINISTRATIVE EXPENSES.  Selling, general and
administrative expenses increased 27.8% during the six-month period ended June
30, 1998 as compared to the same period in 1997, reflecting increased marketing
and promotional activities in the ophthalmic business as well as increased
amortization of intangibles related to product acquisitions. The percentage of
selling, general and administrative expenses to net sales decreased from 30.5%
to 28.5%.
 
    RESEARCH AND DEVELOPMENT.  Research and development expenses increased
170.8% in the period, to $2.0 million from $0.7 million in the same period in
1997. The increase reflects an increased number of products under development,
including TP-1000. Improved gross profits have enabled the Company to devote
substantial resources to developing patented products as part of its long-term
growth strategy.
 
    RELOCATION EXPENSES.  During the six-month period ended June 30, 1997, the
Company recorded $1.5 million in charges related to the relocation of the
ophthalmic business and executive offices from Abita Springs, Louisiana to the
Chicago area. The charges primarily relate to severance and retention bonus
payments as well as a write-down of the Abita Springs facility and equipment to
estimated net realizable value.
 
    INTEREST EXPENSE.  Interest expense for the six months ended June 30, 1998
was $0.5 million which represented an increase of 93.7% as compared to the same
period in 1997 due to higher outstanding debt balances.
 
    NET INCOME.  The Company reported net income of $2.1 million or $0.11 per
diluted share for the six months ended June 30, 1998. The net income for the
comparable prior-year period was $0.2 million or $0.01 per diluted share.
 
YEARS ENDED DECEMBER 31, 1997 AND JUNE 30, 1996
 
    NET SALES.  Net sales increased 24.8% for the year ended December 31, 1997
compared to the year ended June 30, 1996. Ophthalmic-related sales increased
19.5%, primarily due to strong performance in the diagnostic and therapeutic
product lines. The acquisition of Indocyanine Green from Becton, Dickinson & Co.
in April 1997 and the introduction of the Company's generic version of Timolol
Maleate also contributed to the sales increase. Injectable-related sales
increased 33.1%, primarily due to penetration into the hospital market and
strong performance in rheumatology and antidote products, including BAL in Oil,
acquired from Becton, Dickinson & Co. in April 1997. Injectable-related sales
also benefited from a continuing shortage of certain blood-derivative
pharmaceuticals distributed by the Company.
 
    GROSS PROFIT.  Consolidated gross profit increased 57.0% for the year, with
gross margins increasing from 35.2% to 44.4%. The increase in gross margins was
caused by product acquisitions, a shift in ophthalmic sales mix to higher-margin
products and the injectable business' re-engineering of production processes to
reduce costs of manufacturing. Margins on the Company's generic version of
Timolol Maleate have declined at a faster than anticipated rate, due to the
large number of competitors offering the product.
 
    SELLING, GENERAL AND ADMINISTRATIVE EXPENSES.  Selling, general and
administrative expenses increased 36.9%, reflecting increased marketing and
promotional activities in the ophthalmic business, provisions for employee
performance bonuses and expenses associated with the new corporate office
facility.
 
    RESEARCH AND DEVELOPMENT.  Research and development expenses increased
54.4%, reflecting a greater number of products under development. Actual
spending on research and development for the year included approximately $0.7
million pre-funded by Pfizer, Inc. for clinical development of Piroxicam. The
pre-funded development reserve was exhausted during 1997. Additional spending
for data analysis and development of the NDA filing will be reflected in 1998
research and development expenses.
 
                                       19
<PAGE>
    RELOCATION EXPENSES.  During 1997, the Company recorded $1.5 million in
charges related to the relocation of the ophthalmic business and executive
offices from Abita Springs, Louisiana to the Chicago area. The charges primarily
relate to severance and retention bonus payments as well as a write-down of the
Abita Springs facility and equipment to estimated net realizable value.
 
    INTEREST EXPENSE.  Interest expense increased 12.7%, reflecting higher
average outstanding debt balances. Interest income declined 63.7% due to the
liquidation of investments of Piroxicam development funds to finance clinical
trials.
 
    NET INCOME.  Net income for 1997 was $1.8 million or $0.11 per diluted share
compared to $0.8 million or $0.05 per diluted share for the year ended June 30,
1996. The increase in earnings resulted from the above-mentioned items.
 
SIX MONTHS ENDED DECEMBER 31, 1996 AND 1995
 
    NET SALES.  Net sales declined 2.5% for the six months ended December 31,
1996 as compared to the same period in 1995. Ophthalmic-related sales declined
7.6%, primarily due to the Company's decision to discontinue its practice of
granting wholesaler discounts at the end of each quarter. Injectable-related
sales increased 7.2%, primarily due to the acquisition of two anesthesia
products from Janssen Pharmaceutica, Inc. in July 1996.
 
    GROSS PROFIT.  Consolidated gross profit declined 11.1% compared to the
prior year period, with gross margins declining from 38.2% to 34.9%. The decline
can be attributed to under-absorption of plant overhead expenses caused by
decreased unit sales volume in contract manufacturing services.
 
    SELLING, GENERAL AND ADMINISTRATIVE EXPENSES.  Selling, general and
administrative expenses increased 2.5% over the prior year period, primarily due
to increased marketing and promotional activities in the ophthalmic business.
 
    RESEARCH AND DEVELOPMENT.  Research and development expenses increased
69.2%, reflecting an increased number of products in development.
 
    INTEREST EXPENSE.  Interest and other income (expense) increased due to
increased interest expense on higher average outstanding debt balances.
 
    NET INCOME.  Net income for the period was $44,000 or $0.00 per diluted
share compared with $0.8 million or $0.05 per diluted share in the prior year
period. The decline is primarily due to the under-absorption of manufacturing
overhead expenses and the increase in research and development expenditures.
 
YEARS ENDED JUNE 30, 1996 AND 1995
 
    NET SALES.  Consolidated net sales declined 9.5% for the year ended June 30,
1996 compared to the previous year. Ophthalmic-related sales declined 12.4%,
primarily due to the loss of sales of the segment's best-selling allergy
product, which was converted to over-the-counter status in October 1994, and to
the Company's decision to discontinue its practice of granting wholesaler
discounts at the end of each quarter. Injectable-related sales declined 4.5%,
primarily due to loss of contract manufacturing customers which resulted in a
reduction in manufacturing unit volume.
 
    GROSS PROFIT.  Consolidated gross profit declined 21.2% compared to the
prior year period, with gross margins declining from 40.5% to 35.2%. The decline
can be attributed to price pressure on generic pharmaceuticals and
under-absorption of manufacturing overhead due to low unit sales volume.
 
    SELLING, GENERAL AND ADMINISTRATIVE EXPENSES.  Selling, general and
administrative expenses declined 13.5% over the prior year period, primarily due
to cost-cutting activities in the ophthalmic business in response to sales
declines.
 
                                       20
<PAGE>
    RESEARCH AND DEVELOPMENT.  Research and development expenses increased
36.1%, reflecting an increased number of ophthalmic generic products in
development.
 
    ACQUISITION AND SEVERANCE COSTS.  The Company incurred legal, accounting and
severance costs of $0.7 million in 1996 associated with the acquisition of PRL.
 
    INTEREST EXPENSE.  Interest expense increased $0.4 million due to borrowings
for the construction projects at the Company's facilities in Decatur, Illinois.
In 1995, other expense included a $0.3 million charge for decline in market
value of an equity investment.
 
    NET INCOME.  The Company's net income for the period was $0.8 million or
$0.05 per diluted share compared with $2.5 million or $0.15 per diluted share in
the prior year period. The decline is primarily due to the decline in sales,
under-absorption of manufacturing overhead expenses, increased research and
development expenditures and costs related to the acquisition of PRL.

LIQUIDITY AND CAPITAL RESOURCES
 
    As of June 30, 1998, the Company had cash and cash equivalents of $0.6
million. Working capital at that date was $11.4 million versus $5.0 million at
June 30, 1997. At June 30, 1998, the Company had $10.3 million of financing
available under its $25.0 million revolving credit facility.
 
    During the year ended December 31, 1997, the Company generated sufficient
cash from operations to finance its working capital requirements, primarily an
increase in accounts receivable and inventories related to increased sales
volume. Management anticipates additional investment in working capital to
finance continued sales growth. Investing activities, which include purchases of
property, plant and equipment as well as the purchase of product-related
intangible assets, required $6.3 million in cash. Investing activities were
funded through issuance of long-term debt of $4.0 million short-term borrowings
of $1.8 million and proceeds from the sale of stock of $2.1 million. In 1997,
the Company entered into a $15.0 million revolving credit facility, subject to
certain financial covenants. In June 1998,
 
                                       21
<PAGE>
the aggregate borrowing commitment under such revolving credit facility was
increased to $25.0 million. Management believes that cash flow from operations,
in conjunction with borrowing availability under its revolving credit facility,
will be sufficient to meet the cash needs of the business for the next twelve
months.
 
    For the six-month period ended December 31, 1996, the Company generated cash
from operations in excess of working capital requirements. For the period, net
cash provided by operating activities was $2.5 million. The increase in cash
provided by operating activities was primarily related to the increase in
accruals for wholesaler chargebacks. Net cash utilized for investing activities
during the period was approximately $2.0 million which included purchases of
property, plant and equipment as well as the purchase of certain product lines.
These investing activities were partially funded through net sales of
investments and short-term borrowings of $1.5 million.
 
    For the twelve-month period ended June 30, 1996, the Company generated cash
from operations in excess of working capital requirements. For the period, net
cash provided by operating activities was $10,000 as compared to $0.7 million
for the same period in 1995. The decline in cash provided by operating
activities was primarily related to the increase in inventory associated with
new product acquisitions and other factors. Net cash utilized for investing
activities during the period was approximately $0.9 million which included
purchases of property, plant and equipment and product licensing costs. These
investing activities were partially funded through net sales of investments.
 
RECENTLY ISSUED FINANCIAL ACCOUNTING STANDARDS
 
    In June 1997, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards ("SFAS") No. 130, "Reporting
Comprehensive Income," which requires all items of comprehensive income be
reported in a financial statement that is displayed with the same prominence as
other financial statements. Other comprehensive income may include foreign
currency items, minimum pension liability adjustments and unrealized gains and
losses on certain investments in debt and equity securities. The accumulated
balance of other comprehensive income must be displayed separately from retained
earnings and additional paid-in capital in the equity section of a statement of
financial position. The Company has adopted this accounting standard effective
as of January 1, 1998. Because the Company had no other items of comprehensive
income, reclassification of financial statements for earlier periods was not
required.
 
    In June 1997, the FASB issued SFAS No. 131, "Disclosures About Segments of
an Enterprise and Related Information," which redefines how operating segments
are determined and requires disclosure of certain financial and descriptive
information about a Company's operating segments. The Company will adopt this
accounting standard as of December 31, 1998, as required. The Company expects to
continue reporting on ophthalmic and injectable segments.
 
YEAR 2000 ISSUE
 
    The Company utilizes commercially available software to store and process
its business information and transactions. The Company's plans to become Year
2000-compliant involve upgrading the server software of its injectable business
and completing the installation of Year 2000-compliant financial software in the
ophthalmic business. The Company expects to be fully compliant by the end of
1998. The cost of this software upgrade and conversion is estimated at less than
$0.5 million, of which approximately $0.3 million was incurred in 1997. In
addition, the Company has communicated with companies with whom it does
significant business to determine their Year 2000-compliance readiness and the
extent to which the Company is vulnerable to any third-party Year 2000 issues.
Based on these communications, the Company does not believe that such companies'
Year 2000-compliance readiness will have a material adverse effect on the
Company. See "Risk Factors--Risks Related to Year 2000 Issues."

OVERVIEW
 
    Akorn is a specialty pharmaceutical company that develops, manufactures and
markets ophthalmic and injectable sterile pharmaceutical products in the United
States. The Company sells more than 90 diagnostic and therapeutic pharmaceutical
products focused primarily on ophthalmology, anesthesia, antidotes and
rheumatology. The Company also markets ophthalmic surgical instruments and other
supplies and provides contract manufacturing for third parties. The Company is
one of a limited number of U.S. specialty pharmaceutical companies with sterile
manufacturing capabilities. Akorn believes that its sterile manufacturing
capabilities, combined with its ability to manufacture a variety of dosage forms
(solutions, suspensions and ointments), afford it a competitive advantage. Many
of the Company's ophthalmic pharmaceuticals are marketed under its
well-recognized "Akorn" label. For the twelve months ended June 30, 1998,
Akorn's net sales and net income were approximately $49.3 million and $3.8
million, respectively.
 
    Since January 1, 1996, the Company has acquired or licensed 18 specialty
pharmaceutical products. In acquiring or licensing pharmaceutical products, the
Company targets products which complement its existing product lines and enable
it to leverage its existing manufacturing, marketing and distribution
capabilities. After acquiring or licensing a specialty pharmaceutical product,
the Company generally focuses on increasing the marketing and promotion of the
product and integrating it into the Company's existing product lines.
 
    The Company also develops pharmaceutical products internally. Since January
1, 1996, the Company has received approval for nine ANDAs and one NDA for
internally developed sterile pharmaceutical products. In connection with its
strategy to continue to internally develop sterile pharmaceutical products,
Akorn currently has ten ANDAs submitted to the FDA for new products. In
addition, over the next three years, the Company anticipates filing ANDAs for
more than ten additional sterile pharmaceutical products and NDAs for three
proprietary pharmaceutical products which are in various stages of development.
 
INDUSTRY OVERVIEW
 
    UNITED STATES PHARMACEUTICAL MARKET.  In 1997, sales of pharmaceuticals in
the U.S. were approximately $110 billion. While the market is dominated by large
multinational pharmaceutical companies which conduct substantial research and
development on new pharmaceuticals, significant sales are derived from specialty
pharmaceutical products. Industry consolidation and pricing pressures from
cost-containment initiatives have raised the threshold level of sales necessary
for an individual product to justify significant research and development
expenditures and active marketing and promotion from a major pharmaceutical
company. As a result, major pharmaceutical companies have generally elected to
focus on existing proprietary product lines and develop new branded
pharmaceutical products rather than compete in specialty pharmaceutical product
lines. Further, the Company believes that pricing and profit pressures are
leading major pharmaceutical companies to consider divestitures or licensing of
non-core products as a more effective means of realizing value from such
products. Major pharmaceutical companies may choose not to market specialty
pharmaceutical products because: (i) the market size for an individual product
may be too small; (ii) most of such products are no longer subject to patent
protection; (iii) continuing to manufacture such products may no longer be
cost-effective; and (iv) raw materials may be difficult to obtain.
 
    The result of the foregoing factors has been the emergence of pharmaceutical
companies that acquire, license or develop specialty pharmaceutical products.
The Company defines specialty pharmaceutical products as those products which
share several, but not necessarily all, of the following characteristics: (i)
products which no longer fit the strategic focus of major pharmaceutical
companies; (ii) products with annual sales typically in the range of $1 to $50
million; (iii) products which receive
 
                                       23
<PAGE>
minimal promotion from major pharmaceutical companies but compete in
promotion-sensitive markets; (iv) products which have sales levels that are less
likely to become targets of pricing pressure from managed care or third-party
payors, or which have a clear price advantage over alternative treatments; and
(v) products which can leverage the existing sales force, manufacturing
operations and marketing efforts of specialty pharmaceutical companies.
 
    STERILE PHARMACEUTICAL PRODUCTS.  Sterile pharmaceutical products consist of
pharmaceuticals produced using sterile manufacturing techniques, such as aseptic
filling technologies and heat sterilization. Sterile pharmaceutical products are
typically administered in non-solid dosage forms through the injection of
solutions or the application of ointments or suspensions. Several factors limit
the number of specialty pharmaceutical companies that manufacture sterile
pharmaceutical products. The manufacture of sterile pharmaceutical products, as
compared to the production of non-sterile pharmaceutical products such as
tablets, requires more technologically sophisticated processes and personnel
with technical expertise. In addition, substantial capital expenditures are
required to develop and maintain the capability to manufacture sterile products.
Furthermore, the manufacturing and marketing of sterile pharmaceutical products
is subject to extensive governmental regulation. See "--Government Regulation."
 
    All ophthalmic and injectable pharmaceutical products are required to be
manufactured in a sterile process because of the way they are administered to
patients (I.E., through application to the eye or injection). In 1997, the U.S.
ophthalmic and injectable sterile pharmaceutical markets had total sales of
approximately $2.0 billion and $8.2 billion, respectively, which represent
increases of approximately 10.0% and 12.0%, respectively, from 1996. The Company
believes that U.S. sales of ophthalmic and injectable sterile pharmaceutical
products will continue to grow due to a significant number of products coming
off patent and increasing demand due to the aging of the U.S. population.
 
STRATEGY
 
    To capitalize on the trend of major pharmaceutical companies devoting less
resources to specialty pharmaceutical products, the Company focuses on sterile
specialty pharmaceutical products that generally face limited competition. The
Company's objective is to leverage its manufacturing and marketing strengths to
become a leading specialty sterile pharmaceutical products company. To achieve
this objective, the Company seeks to:
 
    PURSUE STRATEGIC ACQUISITIONS OF BRANDED STERILE SPECIALTY PHARMACEUTICAL
PRODUCTS.  In order to expand or complement its ophthalmic and injectable
product lines, the Company intends to continue to pursue strategic acquisitions
of branded sterile specialty pharmaceutical products. The Company focuses on the
acquisition of products that it believes are capable of achieving a substantial
market presence. Since January 1, 1996, the Company has acquired or licensed 14
branded specialty pharmaceutical products. Such products include: (i) Alfenta
and Sufenta, anesthesia-related pharmaceutical products acquired from Janssen
Pharmaceutica, Inc.; (ii) Pilo-20 and Pilo-40, therapeutic glaucoma products
acquired from ALZA Corporation; and (iii) Indocyanine Green, a diagnostic
retinal product acquired from Becton, Dickinson & Co. In addition, the Company
enters into licensing arrangements with respect to third-party products such as
Biolon-TM-, a product used in ophthalmic surgery to which the Company obtained
marketing and distribution rights from Bio-Technology General Ltd. The Company
has dedicated personnel who identify and evaluate potential product acquisitions
and licensing opportunities. After acquiring or licensing a branded specialty
pharmaceutical product, the Company generally focuses on increasing the
marketing and promotion of such product and integrating it into its existing
product lines.
 
    INTERNALLY DEVELOP STERILE SPECIALTY PHARMACEUTICAL PRODUCTS.  The Company
intends to capitalize on its existing research and development expertise to
continue to internally develop sterile specialty pharmaceutical products. Since
January 1, 1996, the Company has received FDA approval for nine ANDAs
 
                                       24
<PAGE>
and one NDA for internally developed pharmaceutical products. The Company
currently has ten ANDAs submitted to the FDA for new products. In addition, over
the next three years, the Company anticipates filing ANDAs for more than ten
additional pharmaceutical products and NDAs for three proprietary pharmaceutical
products which are in various stages of development. The Company's NDA filings
are typically for new indications or uses for existing pharmaceutical products.
These NDAs provide the Company the potential to enter new markets at a lower
cost than by developing new proprietary pharmaceutical compounds. See "Risk
Factors--Dependence on Development of Pharmaceutical Products and Manufacturing
Capabilities." In developing pharmaceutical products, the Company targets
pharmaceuticals which complement its existing products and enable it to leverage
its existing manufacturing and marketing capabilities. The Company also develops
pharmaceutical products in order to eliminate the need to purchase
pharmaceuticals from third-party manufacturers.
 
    LEVERAGE EXISTING INFRASTRUCTURE AND INCREASE OPERATING EFFICIENCIES.  The
Company intends to improve its profitability by leveraging its existing
infrastructure and increasing operating efficiencies. The Company believes that
its research and development, manufacturing and marketing capabilities provide
it with the ability to profitably offer a broad range of specialty sterile
pharmaceutical products. The Company believes that it can use its existing
marketing capabilities to increase sales of specialty pharmaceutical products
with limited additional expenditures on infrastructure. The Company's existing
research and development resources support both ophthalmic and injectable
products. The Company's manufacturing and research and development resources,
including those recently acquired from ARI, provide it with the opportunity to
enhance profitability by internally manufacturing and developing substantially
more of its products. Finally, the Company intends to continue to increase
operating efficiencies by upgrading capital equipment and reengineering
manufacturing processes.
 
    EXPAND STERILE MANUFACTURING AND TECHNICAL CAPABILITIES.  The Company
intends to expand its sterile manufacturing and technical capabilities to
address additional specialty markets and dosage forms. The Company is one of a
limited number of specialty pharmaceutical companies with sterile product
manufacturing capabilities. Through the recent acquisition of ARI, the Company
added the capability to manufacture additional sterile dosage forms (suspensions
and ointments). The Company is also developing the capability to manufacture
controlled-release ophthalmic pharmaceutical products and lyophilized
(freeze-dried) pharmaceutical products. By developing these additional
manufacturing capabilities, the Company intends to expand dosage forms within
existing markets and pursue other markets. See "Risk Factors--Dependence on
Development of Pharmaceutical Products and Manufacturing Capabilities."
 
OPHTHALMIC PRODUCTS
 
    The Company markets therapeutic and diagnostic ophthalmic pharmaceutical
products as well as ophthalmic surgical instruments and supplies. The ophthalmic
business generated net sales of approximately $24.9 million in 1997, which
represented 58.9% of the Company's total net sales for that year. The Company
believes a significant factor in the success of its ophthalmic products has been
its ability to capitalize on its extensive ophthalmic product line and
well-recognized "Akorn" label. The Company attributes its name recognition
primarily to the success of its comprehensive product catalog which is
distributed periodically to approximately 60,000 potential customers, including
ophthalmologists, optometrists, hospitals, pharmacies and clinics. The Company
has an active base of over 15,000 ophthalmic customers who have made at least
one purchase in the last 12 months.
 
    The Company believes it is a leading provider of diagnostic ophthalmic
pharmaceutical products. The Company's diagnostic ophthalmic pharmaceutical
products are primarily for use in physicians' offices and include a complete
line of ophthalmic dilating and constricting solutions, anesthetics and topical
stains. The Company's therapeutic ophthalmic pharmaceutical product line
includes antibiotics, anti-inflammatories, antibiotic/anti-inflammatory
combinations, glaucoma medications, steroids and decongestants/antihistamines.
Currently, substantially all of the Company's diagnostic ophthalmic
 
                                       25
<PAGE>
pharmaceutical products consist of branded products, whereas most of the
Company's therapeutic ophthalmic pharmaceutical products are generic versions of
products which have come off patent. In response to the typical decline in the
price of generic pharmaceutical products over time, the Company has focused
additional resources on developing selected pharmaceutical products for sale
under its "Akorn" label and acquiring or licensing branded ophthalmic
pharmaceutical products. As of June 30, 1998, the Company manufactured
approximately 44.0% of the ophthalmic pharmaceutical products that it sold, and
it obtained the remainder, as well as the ophthalmic surgical instruments and
supplies that it sold, from outside suppliers. As a result of the Company's
acquisition of ARI in July 1998, which provides it with the ability to
manufacture sterile ointments and suspensions, the Company will manufacture a
greater percentage of the ophthalmic pharmaceutical products that it sells.
Ophthalmic surgical instruments and supplies available from the Company include
surgical knives and other surgical instruments, balanced salt solution,
post-operative kits, surgical tapes, eye shields and anti-ultraviolet goggles.
 
    The following are summary descriptions of certain of the Company's
significant ophthalmic products:
 
    FLURESS and FLUORACAINE. Fluress and Fluoracaine are diagnostic ophthalmic
solutions combining fluorescein dye with alternative anesthetics. Fluress and
Fluoracaine are used for procedures such as tonometry (pressure testing),
removal of corneal foreign bodies and other short corneal or conjunctival
procedures. Fluress and Fluoracaine are branded ophthalmic products manufactured
by the Company. A number of fluorescein products with significantly lower market
share compete with Fluress and Fluoracaine in the United States.
 
    INDOCYANINE GREEN ("ICG"). ICG is a diagnostic, water-soluble dye used by
ophthalmologists to study circulation in the back of the retina. ICG is a
branded product subject to an NDA owned by the Company and is manufactured for
it by a third-party contractor. There are no generic equivalents of ICG marketed
in the United States.
 
    GENTAK. Gentak is a broad-spectrum topical antibiotic used to treat a
variety of ophthalmic bacterial infections. It is supplied in 5ml and 15ml
bottles of solution and a 3.5 gram ointment tube. Gentak is a branded generic
equivalent of Gentamycin Sulfate and is currently manufactured for the Company
by a third-party contractor. There are a number of products competing with the
Company in this market.

INJECTABLE PRODUCTS
 
    The Company manufactures and markets a line of specialty injectable
pharmaceutical products. The Company's injectable business generated net sales
of $17.4 million in 1997, which represented 41.1% of the Company's total net
sales for that year.
 
    The Company utilizes its research and development, sterile manufacturing and
marketing capabilities to offer a variety of specialty injectable pharmaceutical
products. Pharmaceutical products manufactured and marketed by the Company
include anesthetics, antidotes and pharmaceuticals used to treat rheumatoid
arthritis. Currently, most of the injectable pharmaceutical products
manufactured and marketed by the Company are generic products. To support its
efforts to sell injectable pharmaceutical products, the Company also supplies
customers with difficult-to-obtain pharmaceutical products, such as
blood-derivative pharmaceuticals, from outside sources. As part of its
injectable business, the Company also manufactures injectable pharmaceutical
products for third parties. See "--Manufacturing."
 
    The following are summary descriptions of certain of the Company's
significant injectable products:
 
    ALFENTA and SUFENTA. Alfenta and Sufenta are therapeutic injectable opioid
analgesics used in inducing and maintaining general anesthesia. Each product is
a branded pharmaceutical manufactured and marketed by the Company. Alfenta and
Sufenta are each subject to an NDA owned by the Company and are primarily sold
to hospitals and outpatient surgery centers. Alfenta is on patent until June
1999 while Sufenta is no longer protected by patent. While a number of
competitors market a generic version of Sufenta, there are no generic
equivalents of Alfenta marketed in the United States.
 
    BAL IN OIL. BAL in Oil is a therapeutic dimercaprol injection used to treat
arsenic, gold and mercury poisoning. BAL in Oil is a branded pharmaceutical
manufactured and marketed by the Company. It is subject to an NDA owned by the
Company and is primarily sold to hospitals and military health care facilities.
There are no generic equivalents of BAL in Oil marketed in the United States.
 
    CYANIDE ANTIDOTE PACKAGES. Cyanide antidote packages are therapeutic kits
that contain the necessary pharmaceuticals to treat cyanide poisoning. The
Company manufactures and markets the pharmaceuticals used in these kits. These
kits compete in the antidote segment of the injectable pharmaceutical product
market and are primarily sold to hospitals and industrial companies. While there
are other products used to treat cyanide poisoning that compete with these
cyanide antidote packages, there are no other kits which compete with these
packages in the U.S. market.
 
    AUROLATE (GOLD SODIUM THIOMALATE INJECTION). Aurolate is a therapeutic
aqueous solution used to treat selected cases of active rheumatoid arthritis in
both adults and juveniles. The product is currently manufactured and marketed by
the Company and is primarily sold to rheumatology clinics and hospitals. There
are no generic equivalents of Aurolate marketed in the United States.

RESEARCH AND DEVELOPMENT
 
    In developing new sterile pharmaceutical products, the Company considers a
variety of factors including: (i) existing or potential marketing opportunities
for such products; (ii) the capability of the Company to manufacture such
products; (iii) whether such products complement existing products of the
Company; (iv) the opportunities to leverage such products with the development
of additional products; and (v) the ability to develop co-marketing
relationships with other pharmaceutical companies. The Company currently has 36
full-time employees that are involved in research and development. The Company's
research and development expenditures for 1995, 1996, 1997 and the first six
months of 1998 were $0.9 million, $1.2 million, $1.9 million and $2.0 million,
respectively.
 
    Since January 1, 1996, the Company has received FDA approval for nine ANDAs
and one NDA for internally developed sterile pharmaceutical products. The
Company currently has ten ANDAs submitted to the FDA for new sterile
pharmaceutical products. In addition, over the next three years, the Company
currently anticipates filing ANDAs for more than ten additional sterile
pharmaceutical products and NDAs for three proprietary pharmaceutical products
which are in various stages of development. See "Risk Factors--Dependence on
Development of Pharmaceutical Products and Manufacturing Capabilities."

(1) Based on 1997 sales as reported by IMS America (other than with respect to
    footnote (2)).
 
(2) Based on internal Company estimates.
 
    Set forth below is a brief description of certain proprietary products
currently under development by the Company which have been publicly announced:
 
    PIROXICAM OPHTHALMIC SOLUTION ("PIROXICAM"). Piroxicam is a non-steroidal
anti-inflammatory drug to be used during cataract surgery. The Company has
acquired the ophthalmic indication for this compound from Pfizer, Inc. The
Company currently anticipates filing an NDA for this product in 1999. According
to industry sources, U.S. sales in the non-steroidal, anti-inflammatory market
were approximately $60.0 million in 1997.
 
    COMBINATION MIOTIC LYOPHILIZED POWDER AND DILUENT ("MLPD"). MLPD is a
therapeutic product to be used to reduce and control post-operative intraocular
pressure increases during and following cataract surgery. The Company has
licensed the world-wide rights to MLPD and currently anticipates filing an NDA
for this product in 2000. According to industry sources, U.S. sales in this
market were approximately $15.0 million in 1997.
 
    TP-1000. TP-1000 is a therapeutic injectable product to be used in the
treatment of migraine headaches. The Company has filed an Investigational New
Drug application for this product and has completed initial dose ranging
studies. The Company currently anticipates filing an NDA for this product in
1999. According to industry sources, U.S. sales in the injectable migraine
treatment market were approximately $50.0 million in 1997.
 
SALES AND MARKETING
 
    The Company maintains a multi-channel sales and marketing structure for its
ophthalmic products. This structure includes 21 field sales representatives who,
together with two district managers, make personal calls on customers, such as
physicians and group practices. In addition, the Company maintains an 11-person
telemarketing team that sells primarily to ophthalmologists, optometrists and
clinics. The Company's eight-person customer service group is responsible for
processing orders, including those originating from the Company's product
catalog. This catalog features over 2,000 ophthalmic products
 
                                       29
<PAGE>
and is distributed to over 60,000 potential customers including
ophthalmologists, optometrists, hospitals, chain-pharmacies and clinics. The
catalog is widely-recognized in the ophthalmic industry and has an active base
of over 15,000 customers who have made at least one purchase in the last 12
months. The Company believes that the catalog's presence with ophthalmologists,
optometrists, hospitals, chain-pharmacies and other customers provides it with
valuable recognition of the "Akorn" name. The Company attempts to leverage this
name recognition in its sales and marketing efforts. The ophthalmic business
also employs a national accounts group consisting of four persons who sell
primarily to full-service wholesalers, retail chains and other group purchasing
organizations.
 
    The Company's sales and marketing efforts for its injectable pharmaceutical
products include employing nine telemarketing and customer service
representatives who sell through telemarketing and direct-mail activities. In
addition, the Company has entered into a significant number of contracts with
national and regional group purchasing organizations to distribute its
injectable products and increase its sales volume. The Company also intends to
build a key-account sales force for the injectable business over the next
several years as new products are introduced. The Company's customers for
injectable pharmaceutical products consist primarily of individual hospitals and
clinics, specialty physicians and group purchasing organizations.
 
MANUFACTURING
 
    The Company's manufacturing facilities, located in Decatur, Illinois and
Somerset, New Jersey, have approximately 131,000 square feet and 30,000 square
feet, respectively. Each facility includes manufacturing, packaging, laboratory,
office and warehouse space. The Company manufactures products in accordance with
cGMP requirements and is licensed by the DEA to procure and produce controlled
substances.
 
    The Company has the ability to manufacture a diverse group of sterile
pharmaceutical products which it believes provides it with a competitive
advantage in the specialty pharmaceutical industry. With the acquisition of the
ARI business in July 1998, the Company added two additional product dosage forms
(ointments and suspensions) for which it did not previously have manufacturing
capabilities. In addition, the Company anticipates adding freeze-dried
(lyophilized) and control-release manufacturing capabilities. This increased
manufacturing capability will allow the Company to further reduce its dependence
on third-party manufacturers and give the Company the opportunity to increase
margins.
 
    As of June 30, 1998, aggregate capacity utilization at the Company's
manufacturing facilities was approximately 50.0%. In general, the Company
transfers production of newly acquired pharmaceutical products and their product
line extensions for which it has production capabilities to its manufacturing
facilities as soon as practicable after regulatory requirements and contractual
obligations are satisfied. See "Risk Factors--Government Regulation." The
Company also maintains integrated manufacturing support systems including
quality assurance, quality control, regulatory compliance, inventory control and
packaging.
 
    The Company requires a supply of quality raw materials and components to
manufacture and package pharmaceutical products for itself and for third parties
with which it has contracted. If for any reason the Company is unable to obtain
sufficient quantities of any of the raw materials or components required to
produce and package its products, it may not be able to deliver its products as
planned, which could have a material adverse effect on the Company's business,
financial condition and results of operations.
 
    CONTRACT MANUFACTURING AND RELATED CAPABILITIES.  The Company manufactures
injectable pharmaceutical products for third parties which allows it to use
excess capacity at its manufacturing facilities. The Company's third-party
manufacturing and related capabilities include product development, process and
product validation, manufacturing and the filing of ANDAs for its customers.
These capabilities allow the Company to market its services to specialty
pharmaceutical companies,
 
                                       30
<PAGE>
development-stage biotechnology companies and contract research organizations
which do not have these capabilities. The Company also manufactures injectable
pharmaceuticals for major pharmaceutical companies which the Company believes
allows it to establish or enhance its relationships with these companies so that
when one of them decides to divest or license a specialty pharmaceutical
product, it is more likely to give the Company an opportunity to acquire or
license the product. For example, the Company manufactures sterile
pharmaceuticals for Janssen Pharmaceutica, Inc. and Pfizer, Inc., from each of
which it has acquired or licensed specialty pharmaceutical products.
 
    The Company has historically limited its sales and marketing efforts in the
contract manufacturing business to personal contacts with major pharmaceutical
companies and limited trade journal advertisements. In 1997, the Company
implemented an expanded marketing program emphasizing the full-service
capabilities of the injectable business' third-party contract manufacturing
operations. Components of this marketing program include increased print
advertising, attendance at trade shows by Company personnel and contributions to
industry journals and publications, as well as a continued emphasis on personal
contacts and relationships with major pharmaceutical companies.
 
PATENTS AND PROPRIETARY RIGHTS
 
    The Company considers the protection of discoveries in connection with its
development activities important to its business. The Company intends to seek
patent protection in the United States and selected foreign countries where
deemed appropriate. To date, the Company has received one U.S. patent for its
ophthalmic and injectable pharmaceutical products and has two additional patent
applications pending. There can be no assurance that the Company will obtain
U.S. or foreign patents or, if obtained, that they will provide substantial
protection or be of commercial benefit.
 
    The Company also relies upon trade secrets, unpatented proprietary know-how
and continuing technological innovation to develop its competitive position. The
Company enters into confidentiality agreements with certain of its employees
pursuant to which such employees agree to assign to the Company any inventions
relating to the Company's business made by them while in the Company's employ.
However, there can be no assurance that others may not acquire or independently
develop similar technology or, if patents are not issued with respect to
products arising from research, that the Company will be able to maintain
information pertinent to such research as proprietary technology or trade
secrets.
 
COMPETITION
 
    The ophthalmic and injectable pharmaceutical industries are highly
competitive, with many established manufacturers, suppliers and distributors
actively engaged in all phases of the business. Most of the Company's
competitors have substantially greater financial and other resources, including
a larger volume of sales, more sales personnel and larger facilities than the
Company. The Company's competitors in the ophthalmic pharmaceutical industry
include: Alcon Laboratories, Inc., owned by Nestle, S.A.; Allergan, Inc.; CIBA
Vision, a division of Novartis, AG; and Bausch & Lomb Incorporated. The
Company's competitors in the injectable pharmaceutical industry include Abbott
Laboratories; Gensia Sicor Inc.; and Steris Laboratories, a division of Schein
Pharmaceutical, Inc. The Company believes that competition in the sale of its
products is based primarily on price, service, availability and product
efficacy. See "Risk Factors--Competition; Uncertainty of Technological Change."
 
GOVERNMENT REGULATION
 
    Virtually all aspects of the Company's business are regulated by federal and
state statutes and government agencies. The developing, testing, manufacturing,
processing, quality, safety, efficacy, formulation, packaging, labeling,
record-keeping, distribution, storage and advertising of the Company's products,
and disposal of waste products arising from such activities, are subject to
regulation by one or
 
                                       31
<PAGE>
more federal agencies, including the FDA. These activities are also regulated by
various agencies of the states and localities in which the Company's products
are sold.
 
    All pharmaceutical manufacturers, including the Company, are subject to
regulation by the FDA under the authority of the FDC Act. Under the FDC Act, the
federal government has extensive administrative and judicial enforcement powers
over the activities of pharmaceutical manufacturers to ensure compliance with
FDA regulations. Those powers include, but are not limited to, the authority to
initiate court action to seize unapproved or non-complying products, to enjoin
non-complying activities, to halt manufacturing operations that are not in
compliance with cGMP, to recall products which present a health risk and to seek
civil monetary and criminal penalties. Other enforcement activities include
refusal to approve product applications or the withdrawal of previously approved
applications. The initiation of any of these enforcement activities, including
the restriction or prohibition on sales of products marketed by the Company or
the halting of manufacturing operations of the Company, could materially
adversely affect the Company's business, financial condition and results of
operations.
 
    All "new drugs" must be the subject of an NDA, and all generic equivalents
must be the subject of an ANDA, before they may be marketed in the United
States. Certain prescription drugs are not currently required to be the subject
of an approved NDA or ANDA but, rather, may be marketed pursuant to an FDA
regulatory enforcement policy permitting continued marketing of those drugs
until the FDA determines whether they are safe and effective. The FDA has the
authority to withdraw existing NDA or ANDA approvals and to review the
regulatory status of products marketed under the enforcement policy. The FDA may
require an approved NDA or ANDA for any drug product marketed under the
enforcement policy if new information reveals questions about the drug's safety
or effectiveness. All drugs must be manufactured in conformity with cGMPs and
drug products subject to an approved NDA or ANDA must be manufactured,
processed, packaged, held, and labeled in accordance with information contained
in the NDA or ANDA.
 
    The Company and its third-party manufacturers are subject to periodic
inspection by the FDA to assure such compliance. The FDA imposes additional
stringent requirements on the manufacture of sterile pharmaceutical products to
ensure the sterilization processes and related control procedures consistently
produce a sterile product. Additional sterile manufacturing requirements include
the submission for expert review of detailed documentation for sterilization
process validation in drug applications beyond those required for general
manufacturing process validation. Various sterilization process requirements are
the subject of detailed FDA guidelines, including requirements for the
maintenance of microbiological control and quality stability. Pharmaceutical
products must be distributed, sampled and promoted in accordance with FDA
requirements. The FDA also regulates drug labeling and the advertising of
prescription drugs.
 
    While the Company believes that all of its current pharmaceuticals are
lawfully marketed in the United States under current FDA enforcement policies or
have received the requisite agency approvals for manufacture and sale, such
marketing authority is subject to withdrawal by the FDA. In addition,
modifications or enhancements of approved products are in many circumstances
subject to additional FDA approvals which may or may not be granted and which
may be subject to a lengthy application process. The Company's and its
third-party manufacturers' manufacturing facilities are continually subject to
inspection by such governmental agencies and manufacturing operations could be
interrupted or halted in any such facilities if such inspections prove
unsatisfactory.
 
    A number of products marketed by the Company are "grandfathered" drugs which
are permitted to be manufactured and marketed without FDA-issued ANDAs or NDAs
on the basis of their having been marketed prior to enactment of relevant
sections of the FDC Act. The regulatory status of these products is subject to
change and/or challenge by the FDA, which could establish new standards and
limitations for manufacturing and marketing such products, or challenge the
evidence of prior manufacturing and marketing upon which grandfathering status
is based. The Company is not aware of any current effort by
 
                                       32
<PAGE>
the FDA to change the status of any of its "grandfathered" products, but there
is no assurance that such initiatives will not occur in the future.
 
    ANDA PROCESS.  FDA approval is required before a generic equivalent to a
previously approved brand drug or new dosage form of an existing brand drug can
be marketed. The Company usually receives approval for such products by
submitting an ANDA to the FDA. When processing an ANDA, the FDA waives the
requirement of conducting complete clinical studies, although it may require
bioavailability and/or bioequivalence studies. "Bioavailability" indicates the
rate and extent of absorption and levels of concentration of a drug product in
the blood stream needed to produce a therapeutic effect. "Bioequivalence"
compares the bioavailability of one drug product with another, and when
established, indicates that the rate of absorption and levels of concentration
of a generic drug in the body are substantially equivalent to the previously
approved drug. An ANDA may be submitted for a drug on the basis that it is
bioequivalent to a previously listed drug, contains the same active ingredient,
has the same route of administration, dosage form, and strength as the listed
drug, and otherwise complies with legal and regulatory requirements.
 
    Among the requirements for drug approval by the FDA is that the Company's
manufacturing procedures and operations conform to cGMPs. The cGMP regulations
must be followed at all times during the manufacture, storage and distribution
of pharmaceutical products. In complying with the standards set forth in the
cGMP regulations, the Company must continue to expend time, money and effort in
the areas of production, quality control and record keeping to ensure full
compliance.
 
    If the FDA believes a company is not in compliance with cGMPs, certain
sanctions are imposed upon that company including: (i) withholding from the
company new drug approvals as well as approvals for supplemental changes to
existing applications; (ii) preventing the company from receiving the necessary
export licenses to export its products; and (iii) classifying the company as an
"unacceptable supplier" and thereby disqualifying the company from selling
products to federal agencies. The Company believes it is currently in compliance
with cGMPs.
 
    In May 1992, the Generic Drug Enforcement Act (the "Generic Act") was
enacted. The Generic Act, a result of the legislative hearings and
investigations into the generic drug approval process, allows the FDA to impose
debarment and other penalties on individuals and companies that commit certain
illegal acts relating to the generic drug approval process. In some situations,
the Generic Act requires the FDA to debar (i.e., not accept or review ANDAs for
a period of time) a company or an individual that has committed certain
violations. It also provides for temporary denial of approval of applications
during the investigation of certain violations that could lead to debarment and
also, in more limited circumstances, provides for the suspension of the
marketing of approved drugs by the affected company. Lastly, the Generic Act
allows for civil penalties and withdrawal of previously approved applications.
Neither the Company nor any of its employees have ever been subject to
debarment.
 
    NDA PROCESS.  FDA approval is required before any new drug can be marketed.
An NDA is a filing submitted to the FDA to obtain approval of a drug not
eligible for an ANDA and must contain complete pre-clinical and clinical safety
and efficacy data or a right of reference to such data. Before administering a
new drug in healthy human subjects may begin, stringent government requirements
for preclinical data must be satisfied. The pre-clinical data, typically
obtained from studies in animal species, as well as from laboratory studies, are
submitted in an Investigational New Drug ("IND") application, or its equivalent
in countries outside the United States, where clinical trials are to be
conducted. The preclinical data must provide an adequate basis for evaluating
both the safety and the scientific rationale for the initiation of clinical
trials.
 
    Clinical trials are typically conducted in three sequential phases, although
the phases may overlap. In Phase I, which frequently begins with the initial
introduction of the compound into healthy human subjects prior to introduction
into patients, the product is tested for safety, adverse effects, dosage,
tolerance absorption, metabolism, excretion and other elements of clinical
pharmacology. Phase II
 
                                       33
<PAGE>
typically involves studies in a small sample of the intended patient population
to assess the efficacy of the compound for a specified indication, to determine
dose tolerance and the optimal dose range as well as to gather additional
information relating to safety and potential adverse effects. Phase III trials
are undertaken to further evaluate clinical safety and efficacy in an expanded
patient population at typically dispersed study sites, in order to determine the
overall risk-benefit ratio of the compound, and to provide an adequate basis for
product labeling. Each trial is conducted in accordance with certain standards
under protocols that detail the objects of the study, the parameters to be used
to monitor safety and efficacy criteria to be evaluated. Each protocol must be
submitted to the FDA as part of the IND. In some cases, the FDA allows a company
to rely on data developed in foreign countries and therefore not independently
repeat some or all of those studies.
 
    Data from preclinical testing and clinical trials are submitted to the FDA
as an NDA for marketing approval and to other health authorities as a marketing
authorization application. The process of completing clinical trials for a new
drug may take several years and require the expenditure of substantial
resources. Preparing an NDA or marketing authorization application involves
considerable data collection, verification, analysis and expense, and there can
be no assurance that approval from the FDA or any other health authority will be
granted on a timely basis, if at all. The approval process is affected by a
number of factors, primarily the risks and benefits demonstrated in clinical
trials as well as the severity of the disease and the availability of
alternative treatments. The FDA or other health authorities may deny an NDA or
marketing authorization application if the regulatory criteria are not
satisfied, or such authorities may require additional testing or information.
 
    Even after initial FDA or other health authority approval has been obtained,
further studies, including Phase IV post-marketing studies, may be required to
provide additional data on safety. Additional studies generally also are
required to gain approval for the use of a product as a treatment for clinical
indications other than those for which the product was initially tested. Also,
the FDA or other regulatory authorities require post-marketing reporting to
monitor the adverse effects of the drug. Results of post-marketing programs may
limit or expand the further marketing of the products. Further, if there are any
modifications to the drug, including changes in indication, manufacturing
process or labeling or a change in the manufacturing facility, an application
seeking approval of such changes must be submitted to the FDA or other
regulatory authority. Additionally, the FDA regulates post-approval promotional
labeling and advertising activities to assure that such activities are being
conducted in conformity with statutory and regulatory requirements. Failure to
adhere to such requirements can result in regulatory actions which could have a
material adverse effect on the Company's business, results of operations and
financial condition.
 
    The Company also manufactures and sells drugs which are "controlled
substances" as defined in the federal Controlled Substances Act and similar
state laws, which establishes, among other things, certain licensing, security
and record keeping requirements administered by the DEA and similar state
agencies, as well as quotas for the manufacture, purchase and sale of controlled
substances. The DEA could limit or reduce the amount of controlled substances
which the Company is permitted to manufacture and market. The Company has not
experienced sanctions or fines for non-compliance with the foregoing
regulations, but no assurance can be given that any such sanctions or fines
would not have a material adverse effect on the Company's business, financial
condition and results of operations.
 
EMPLOYEES
 
    As of July 20, 1998, the Company employed 309 persons, consisting of 157
manufacturing employees, 80 sales and marketing employees, 36 research and
development employees and 36 management and other employees. The Company's
success depends in large part on attracting and retaining talented and
experienced personnel. See "Risk Factors--Need to Attract and Retain Key
Personnel in Highly Competitive Marketplace." None of the Company's employees
are represented by labor unions and the Company considers its relationship with
its employees to be good.

FACILITIES
 
    The Company's headquarters and administrative, sales and marketing
operations are based in approximately 11,000 square feet of leased space located
in an office building in Lincolnshire, Illinois. In September 1998, the Company
anticipates moving its principal executive offices to an approximately 38,000
square foot office and warehouse facility in Buffalo Grove, Illinois. The
Company's former headquarters, consisting of approximately 30,000 square feet in
Abita Springs, Louisiana, is currently subject to a pending contract for sale
which the Company expects to close by the end of 1998.
 
    The Company owns a 55,000 square-foot manufacturing facility in Decatur,
Illinois and leases a 30,000-square foot manufacturing facility in Somerset, New
Jersey. The Company also owns a 76,000 square foot facility located in Decatur,
Illinois. This facility is currently used for packaging, distribution,
warehousing and office space. The Company also leases approximately 7,000 square
feet of office and warehousing space in San Clemente, California. The Company
considers its facilities adequate to accommodate growth in the foreseeable
future.
 
LEGAL PROCEEDINGS
 
    From time to time, the Company is a party to legal proceedings arising in
the ordinary course of business. The Company believes that it is not a party to
any legal proceedings which, if adversely decided, would have a material adverse
effect on the Company's business, financial condition and results of operations.

1988 INCENTIVE COMPENSATION PROGRAM
 
    Under the 1988 Incentive Compensation Program (the "Incentive Program") any
officer or key employee of the Company is eligible to receive non-qualified
options as designated by the Board of Directors. Currently, 4,500,000 shares of
the Common Stock are reserved to be issued under the Incentive Program of which
approximately 2.3 million shares were still available as of June 30, 1998. The
exercise price of the options granted under the Incentive Program may not be
less than 50% of the fair market value of the shares subject to the option on
the date of grant, as determined by the Board of Directors. All options granted
under the Incentive Program during the year ended December 31, 1997, the six
months ended December 31, 1996 and the years ended June 30, 1996 and 1995 have
exercise prices equivalent to the market value of the Common Stock on the date
of grant. Options granted under the Incentive Program generally vest over a
period of three years and expire within a period of five years.
 
1991 STOCK OPTION PLAN FOR DIRECTORS
 
    Under the 1991 Stock Option Plan for Directors (the "Directors' Plan")
persons elected as directors of the Company are granted nonqualified options at
the fair market value of the shares subject to the option on the date of the
grant. Each director of the Company is automatically granted an option each year
to acquire 5,000 shares under the Directors' Plan on the day following the
annual meeting of shareholders. As of December 31, 1997, 500,000 shares of the
Common Stock were reserved to be issued under the Directors' Plan. Options
granted under the Directors' Plan are exercisable six months after the date of
grant and expire five years from the date of grant.

EMPLOYEE STOCK PURCHASE PLAN
 
    The Akorn, Inc. Employee Stock Purchase Plan (the "Stock Purchase Plan")
permits eligible employees to acquire shares of the Company's common stock
through payroll deductions not exceeding 15.0% of gross compensation, at a 15.0%
discount from market price. A maximum of 1,000,000 shares of the Company's
common stock may be acquired under the terms of the Stock Purchase Plan.
Purchases of shares were issued from treasury stock and approximated 56,000,
18,000 and 9,000 shares, respectively, during the fiscal year ended June 30,
1996, the six months ended December 31, 1996 and the fiscal year ended December
31, 1997.
 
RETIREMENT PLAN
 
    All employees who have attained the age of 21 with six months of service are
eligible for participation in the Company's 401(k) Plan. The Company's matching
contribution is a discretionary percentage of the amount contributed by each
employee.
 
EMPLOYMENT AGREEMENTS
 
    In May 1996, the Company entered into an employment agreement with Floyd
Benjamin providing for an annual salary of $200,000, plus bonuses determined by
a formula stated in the agreement. The Board of Directors has the discretion to
increase Mr. Benjamin's annual salary. Mr. Benjamin's current annual salary is
$212,000.
 
    The agreement terminates three years from inception. If Mr. Benjamin's
employment is otherwise terminated by the Company without "cause" as defined in
the agreement, he is entitled to a lump sum payment equal to his salary through
the remainder of the employment term, plus any performance-based bonus to which
he would have been entitled had the performance goals been achieved. Mr.
Benjamin is also subject to non-compete and confidentiality provisions pursuant
to the terms of his employment agreement.
 
    The Company may pay up to 50.0% of any of Mr. Benjamin's bonuses in options
to purchase Common Stock, with such options being valued at 25.0% of the market
price at the time the options are issued. The options will be issued under the
Incentive Program, on terms similar to other options issued under the Incentive
Program.

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
 
    For services performed by John N. Kapoor, Ph.D. in connection with the
Company's acquisition of Taylor Pharmaceuticals, the John N. Kapoor Trust, an
entity controlled by Dr. Kapoor (the "Kapoor Trust"), received 125,000 shares of
Common Stock which were subject to forfeiture if the market price of the Common
Stock did not reach $5.00 by January 15, 1996. In August 1995, the Company, the
Kapoor Trust and Dr. Kapoor entered into an agreement under which: (i) the
forfeiture period was extended to January 15, 1998; (ii) the forfeiture would
not occur in the event that persons unaffiliated with Dr. Kapoor acquired
beneficial ownership of more than 50% of the outstanding common stock of the
Company; and (iii) Dr. Kapoor waived his right to receive $40,000 otherwise
payable to him by the Company for serving as Chairman of the Board in fiscal
1996. On May 23, 1997, the Company, the Kapoor Trust and Dr. Kapoor entered into
an agreement under which (i) the forfeiture period was extended to January 15,
2000; and (ii) Dr. Kapoor waived his right to receive $40,000 otherwise payable
to him by the Company for serving as Chairman of the Board in fiscal 1997. On
February 20, 1998, the Common Stock closed at $5.1875 with the result that the
above described forfeiture provision was terminated.
 
    Under agreements between the Company and the Kapoor Trust, the Kapoor Trust
is entitled to designate up to two individuals to be nominated and recommended
by the Board of Directors for election as a director. In 1998, Dr. Kapoor was
nominated by the Kapoor Trust.
 
    In November 1991, the Company and EJ Financial entered into a consulting
agreement whereby EJ Financial serves as an independent consultant which
provides management consulting services relating to the Company's strategic
corporate objectives, primarily in the area of new product opportunities. In
exchange for these services, EJ Financial is paid a consulting fee in the amount
of $1,500 per month in addition to reimbursement by the Company of certain
related expenses.

                          DESCRIPTION OF CAPITAL STOCK
 
GENERAL
 
    The authorized capital stock of the Company consists of 40,000,000 shares of
Common Stock, no par value, and 5,000,000 shares of Preferred Stock, par value
$1.00 per share (the "Preferred Stock"). Prior to the consummation of this
Offering, the Company will have outstanding 17,952,063 shares of Common Stock
and no shares of Preferred Stock. Upon completion of this Offering, the Company
will have outstanding 22,952,063 shares of Common Stock and no shares of
Preferred Stock.
 
COMMON STOCK
 
    Holders of Common Stock are entitled to one vote per share for the election
of directors and all other matters submitted for stockholder vote, except
matters submitted to the vote of another class or series of shares. Holders of
Common Stock are not entitled to cumulative voting rights. Therefore, the
holders of a majority of the shares voting for the election of directors can
elect all of the directors if they choose to do so. The holders of Common Stock
are entitled to dividends in such amounts and at such times, if any, as may be
declared by the Board of Directors out of funds legally available therefor. The
Company has not paid any dividends on its Common Stock since 1991 and does not
anticipate paying any cash dividends on such Common Stock in the foreseeable
future. See "Dividend Policy." Upon liquidation, dissolution or winding up of
the Company, the holders of Common Stock are entitled to share ratably in all
net assets available for distribution to stockholders after payments to
creditors. The Common Stock is not redeemable and has no preemptive or
conversion rights.
 
    The rights of the holders of Common Stock are subject to the rights of the
holders of any Preferred Stock which may, in the future, be issued. All
outstanding shares of Common Stock are, and the shares of Common Stock to be
sold by the Company in this Offering when issued will be, duly authorized,
validly issued, fully paid and nonassessable.
 
PREFERRED STOCK
 
    The Board of Directors has the authority to issue the Preferred Stock in one
or more series and to fix the price, rights, preferences, privileges and
restrictions thereof, including dividend rights, dividend rates, conversion
rights, voting rights, terms of redemption, redemption prices, liquidation
preferences and the number of shares constituting any series or the designation
of such series, without further vote or action by the stockholders. The issuance
of Preferred Stock may have the effect of delaying, deferring or preventing a
change in control of the Company without further action by the stockholders and
may adversely affect the voting and other rights of the holders of Common Stock.
The issuance of Preferred Stock with voting and conversion rights may adversely
affect the voting power of the holders of Common Stock, including the loss of
voting control to others.
 
LIMITATION OF LIABILITY AND INDEMNIFICATION
 
    LIMITATION OF LIABILITY.  As permitted by the Business Corporation Law of
Louisiana (the "BCLL"), the Company's Articles of Incorporation provides that no
director or officer of the Company shall be personally liable for monetary
damages to the Company or its shareholders for breach of fiduciary duty as a
director or officer except for: (i) any breach of the director's or officer's
duty of loyalty to the Company or its shareholders; (ii) acts or omissions not
in good faith or which involve intentional misconduct or knowing violation of
law; (iii) authorizing illegal dividends or redemptions; or (iv) any transaction
from which the director or officer derived an improper personal benefit. In
addition, the provision applies only to claims against a director or officer
arising out of his or her role as a director or officer and not in any other
capacity. Further, liability of a director for violations of the federal
securities laws will not be limited by this provision. Directors and officers
will, however, no longer be liable for monetary damages arising from decisions
involving violations of the duty of care which could be deemed grossly
negligent.
 
                                       43
<PAGE>
    INDEMNIFICATION.  The Company's By-laws provide that any person shall be
indemnified who was or is a party or is threatened to be made a party to any
action, suit or proceeding, whether civil, criminal, administrative or
investigative (including any action by or in the right of the Company) by reason
of the fact that he or she is or was a director, officer, employee or agent of
the Company, or is or was serving at the request of the Company as a director,
officer, employee or agent of the Company of another entity, against expenses
actually and reasonably incurred by him or her in connection with such action,
suit or proceeding, if he or she acted in good faith and in a manner reasonably
believed to be in or not opposed to the best interest of the corporation or had
no reason to believe his or her conduct was unlawful. In accordance with the
BCLL, indemnification shall be made by the Company only as authorized in a
specific case upon a determination that the applicable standard has been met.
Such determination may be made: (i) by a majority vote of a quorum of the board
of directors who are disinterested; (ii) by independent counsel; or (iii) by the
shareholders. The Company's By-laws permit the Company to procure insurance on
behalf of any person who is or was a director, officer, employee or agent of the
Company, or is or was serving at the request of the Company as a director,
officer, employee or agent of the Company of another entity, against liability
asserted against him or her in any such capacity, or arising out of his or her
status as such, whether or not the Company would have the power to indemnify him
or her against such liability under the BCLL. 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 foregoing
provisions, or otherwise, the Company has been advised that in the opinion of
the Commission such indemnification is against public policy as expressed in the
Securities Act and is, therefore, unenforceable.
 
REGISTRATION RIGHTS
 
    Pursuant to a Stock Registration Rights Agreement dated as of November 15,
1990, between the Company and the Kapoor Trust, the Company has granted the
Kapoor Trust certain "demand" and "piggyback" registration rights (collectively,
the "Kapoor Registration Rights") with respect to any shares of Common Stock
held by the Kapoor Trust (4,207,400 shares as of June 30, 1998). Subject to
certain conditions, the demand registration rights permit the Kapoor Trust to
request one demand registration. Subject to certain conditions, the piggyback
registration rights permit the Kapoor Trust to include its shares of Common
Stock in a registration of Common Stock (except pursuant to Form S-4 or Form
S-8) or in connection with an exchange offering or offering of securities solely
to existing holders of the Company's securities. The Company will bear expenses
arising from exercise of the Kapoor Registration Rights, except that the Company
shall not pay any underwriting discounts or commissions.
 
    In connection with the acquisition of PRL in May 1996, the Company granted
the Benjamin Family Trust, the Yankoff Revocable Living Trust and the Gencarella
Revocable Living Trust (collectively, the "PRL Shareholders") certain
"piggyback" registration rights with respect to 1,400,000 shares of Common Stock
that were issued in the acquisition. Subject to certain conditions, the
piggyback registration rights permit the PRL Shareholders to include their
shares of Common Stock in a registration of Common Stock (except pursuant to
Form S-4 or S-8). The PRL Shareholders are responsible for any underwriting
discounts and selling commissions and must pay their pro rata share of all
filing fees and blue-sky expenses.
 
TRANSFER AGENT AND REGISTRAR
 
    The transfer agent and registrar for the Common Stock is Harris Trust and
Savings Bank, Chicago, Illinois.

                        SHARES ELIGIBLE FOR FUTURE SALE
 
    Immediately after completion of this Offering, the Company will have
22,952,063 shares of Common Stock outstanding. Of these shares, 21,952,063
shares (including the 5,540,000 shares sold pursuant to this Offering) will be
freely tradable without restriction or further registration under the Securities
Act other than those shares held by "affiliates" of the Company. The remaining
1,000,000 shares will become eligible for resale in December 1998, subject to
the limitations set forth under Rule 144 under the Securities Act, as
applicable.
 
    Shares of Common Stock in the hands of "affiliates" are generally deemed
"restricted shares" under Rule 144. The number of shares of Common Stock
available for sale in the public market is limited by restrictions under the
Securities Act and lock-up agreements under which certain holders of such shares
have agreed not to sell or otherwise dispose of any of their shares for a period
ranging from 90 to 180 days after the effective date of this Offering without
the prior written consent of BT Alex. Brown Incorporated. All of the "restricted
shares" in the hands of "affiliates" of the Company are eligible for sale by the
holders thereof (other than 1,000,000 shares held by the Kapoor Trust) subject,
however, to the manner of sale, volume, notice information requirements and
other restrictions (other than the holding period) of Rule 144, as applicable.
 
    In general, under Rule 144 of the Securities Act as currently in effect,
beginning 90 days after this Offering, a person (or persons whose shares are
aggregated) who has beneficially owned "restricted shares" for at least one
year, including a person who may be deemed an "affiliate" of the Company, is
entitled to sell within any three-month period a number of shares of Common
Stock that does not exceed the greater of 1% of the then-outstanding shares of
Common Stock of the Company (229,520 shares after giving effect to this
Offering) or the average weekly trading volume of the Common Stock as reported
through the Nasdaq National Market during the four calendar weeks preceding such
sale. Sales under Rule 144 of the Securities Act are subject to certain
restrictions relating to manner of sale, notice and the availability of current
public information about the Company. In addition, under Rule 144(k) of the
Securities Act, a person who is not an "affiliate" of the Company at any time 90
days preceding a sale, and who has beneficially owned shares for at least two
years, would be entitled to sell such shares immediately following this Offering
without regard to the volume limitations, manner of sale provisions or notice or
other requirements of Rule 144 of the Securities Act.
 
    The Company is party to a registration rights agreement with the Kapoor
Trust pursuant to which the Kapoor Trust was granted certain "demand" and
"piggyback" registration rights with respect to any shares of Common Stock held
by the Kapoor Trust (4,207,400 shares as of June 30, 1998). In addition, certain
shareholders of the Company received "piggyback" registration rights in
connection with the acquisition of PRL in 1996 relating to the 1,400,000 shares
of Common Stock issued in such acquisitions. See "Description of Capital
Stock--Registration Rights." Options to purchase approximately 1,088,894 shares
of Common Stock will be exercisable upon consummation of the Offering. No
prediction can be made as to the effect, if any, that sales of additional shares
or the availability of such additional shares for sale will have on the market
price of the Common Stock. Sales of substantial amounts of Common Stock in the
public market could have an adverse effect on the market price of the Common
Stock.

    The Underwriting Agreement provides that the obligations of the Underwriters
are subject to certain conditions precedent and that the Underwriters will
purchase all shares of the Common Stock offered hereby if any of such shares are
purchased.
 
    The Company has been advised by the Representatives of the Underwriters that
the Underwriters propose to offer the shares of Common Stock to the public at
the public offering price set forth on the cover page of this Prospectus and to
certain dealers at such price less a concession not in excess of $    per share.
The Underwriters may allow, and such dealers may reallow, a concession not in
excess of $    per share to certain other dealers. After the public offering,
the offering price and other selling terms may be changed by the Representatives
of the Underwriters.
 
    The Company has granted to the Underwriters an option, exercisable not later
than 30 days after the date of this Prospectus, to purchase up to 831,000
additional shares of Common Stock at the public offering price less the
underwriting discounts and commissions set forth on the cover page of this
Prospectus. To the extent that the Underwriters exercise such option, each of
the Underwriters will have a firm commitment to purchase approximately the same
percentage thereof that the number of shares of Common Stock to be purchased by
it in the above table bears to 5,540,000 and the Company will be obligated,
pursuant to the option, to sell such shares to the Underwriters. The
Underwriters may exercise such option only to cover over-allotments made in
connection with the sale of the Common Stock offered hereby. If purchased, the
Underwriters will offer such additional shares on the same terms as those on
which the 5,540,000 shares are being offered.
 
    The Company has agreed to indemnify the Underwriters against certain
liabilities, including liabilities under the Securities Act.
 
    The Company and holders of approximately 5,064,793 shares of Common Stock
have agreed not to offer, sell or otherwise dispose of any of such Common Stock
for a period ranging from 90 to 180 days after the date of this Prospectus
without the prior consent of BT Alex. Brown Incorporated on behalf of the
Representatives of the Underwriters.
 
    The Underwriters have advised the Company that, pursuant to Regulation M
under the Securities Exchange Act of 1934, as amended, certain persons
participating in this Offering may engage in transactions, including stabilizing
bids, syndicate covering transactions or the imposition of penalty bids, which
may have the effect of stabilizing or maintaining the market price of the Common
Stock at a level above that which might otherwise prevail in the open market. A
"stabilizing bid" is a bid for or the purchase of the Common Stock on behalf of
the Underwriters for the purpose of fixing or maintaining the price of the
Common Stock. A "syndicate covering transaction" is the bid for the purchase of
the Common Stock on behalf of the Underwriters to reduce a short position
incurred by the Underwriters in connection with this Offering. A "penalty bid"
is an arrangement permitting the Underwriters to reclaim
 
                                       46
<PAGE>
the selling concession otherwise accruing to an Underwriter or dealer in
connection with this Offering if the Common Stock originally sold by such
Underwriter or dealer is purchased by the Underwriters in a syndicate covering
transaction and has therefore not been effectively placed by such Underwriter or
dealer. The Underwriters have advised the Company that such transactions may be
effected on the Nasdaq National Market or otherwise and, if commenced, may be
discontinued at any time.
 
    As permitted by Rule 103 under the Securities Exchange Act of 1934, as
amended, Underwriters or prospective underwriters that are market makers
("passive market makers") in the Common Stock may make bids for or purchases of
Common Stock on the Nasdaq National Market until such time, if any, when a
stabilizing bid for such securities has been made. Rule 103 generally provides
that: (i) a passive market maker's net daily purchases of the Common Stock may
not exceed 30% of its average daily trading volume in such securities for the
two full consecutive calendar months (or any 60 consecutive days ending within
the ten days) immediately preceding the filing date of the Registration
Statement of which this Prospectus forms a part; (ii) a passive market maker may
not effect transactions or display bids for the Common Stock at a price that
exceeds the highest independent bid for the Common Stock by persons who are not
passive market makers; and (iii) bids made by passive market makers must be
identified as such.
 
                                 LEGAL MATTERS
 
    Certain legal matters in connection with the Common Stock offered hereby are
being passed upon for the Company by Winston & Strawn, Chicago, Illinois and
Jones Walker Walchter Poitevent Carrere & Denegre, LLP, New Orleans, Louisiana.
Certain legal matters will be passed upon for the Underwriters by Alston & Bird
LLP, Atlanta, Georgia.

                         REPORT OF INDEPENDENT AUDITORS
 
To the Board of Directors and Shareholders of Akorn, Inc.:
 
    We have audited the accompanying consolidated balance sheets of Akorn, Inc.
and subsidiaries as of December 31, 1997 and 1996, and the related consolidated
statements of income, shareholders' equity, and cash flows for the year ended
December 31, 1997, the six months ended December 31, 1996 and the years ended
June 30, 1996 and 1995. 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 in accordance with generally accepted auditing
standards. Those standards 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. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
    In our opinion, such consolidated financial statements present fairly, in
all material respects, the financial position of Akorn, Inc. and subsidiaries at
December 31, 1997 and 1996, and the results of their operations and their cash
flows for the year ended December 31, 1997, the six months ended December 31,
1996 and the years ended June 30, 1996 and 1995 in conformity with generally
accepted accounting principles.

              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                  (UNAUDITED)
 
NOTE A--BASIS OF PRESENTATION
 
    The accompanying unaudited condensed consolidated financial statements
include the accounts of Akorn, Inc. and its wholly owned subsidiaries (the
Company). Intercompany transactions and balances have been eliminated in
consolidation. These financial statements have been prepared in accordance with
generally accepted accounting principles for interim financial information and
accordingly do not include all the information and footnotes required by
generally accepted accounting principles for complete financial statements. In
the opinion of management, all adjustments (consisting of normal recurring
accruals) considered necessary for a fair presentation have been included.
Operating results for the three- and six-month periods ended June 30, 1998 are
not necessarily indicative of the results that may be expected for a full year.
For further information, refer to the consolidated financial statements and
footnotes for the year ended December 31, 1997, included in the Company's Annual
Report on Form 10-K.
 
NOTE B--NONCASH TRANSACTIONS
 
    On June 5, 1998, a former employee exercised options for 105,000 shares of
the Company's common stock. The individual tendered approximately 22,000 shares
of the Company's outstanding stock as consideration for the option exercise and
approximately 33,000 shares to satisfy the personal income tax withholding
requirements of the transaction, all of which was recorded as treasury stock.
The net effect of this transaction was to increase accrued liabilities by
$280,000, increase common stock and paid in capital by $185,000, and increase
treasury stock by $465,000.
 
NOTE C--SUBSEQUENT EVENTS
 
    On July 14, 1998, the Company announced the acquisition of three ophthalmic
diagnostic products from Allergan, Inc. The Company paid Allergan $4.65 million,
with $2.0 million paid upon closing, $1.5 million payable one year from the
closing and $1.15 million payable two years from the closing.
 
    On July 16, 1998, the Company announced the acquisition of the Advanced
Remedies, Inc. ophthalmic manufacturing and development operation from Sidmak
Laboratories, Inc. The Company paid Sidmak approximately $4.0 million cash,
financed through the Company's line of credit.
 
NOTE D--RECENT ACCOUNTING PRONOUNCEMENTS
 
    In June 1997, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards ("SFAS") No. 130, "Reporting
Comprehensive Income," which requires all items of comprehensive income be
reported in a financial statement that is displayed with the same prominence as
other financial statements. Other comprehensive income may include foreign
currency items, minimum pension liability adjustments and unrealized gains and
losses on certain investments in debt and equity securities. The accumulated
balance of other comprehensive income must be displayed separately from retained
earnings and additional paid-in capital in the equity section of a statement of
financial position. The Company has adopted this accounting standard January 1,
1998, as required. Currently, the Company does not have any items that qualify
as "other comprehensive income." Accordingly, no separate statement has been
presented herein.
 
    In June 1997, the FASB issued SFAS No. 131, "Disclosures About Segments of
an Enterprise and Related Information," which redefines how operating segments
are determined and requires disclosure of certain financial and descriptive
information about a company's operating segments. The Company will adopt this
accounting standard as of December 31, 1998, as required. The Company expects to
continue reporting on ophthalmic and injectable segments.

</TABLE>
 
    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.
Significant estimates and assumptions relate to the reserve for wholesaler
chargebacks, the reserve for slow-moving and obsolete inventory and to the
carrying value of intangible assets.
 
    REVENUE RECOGNITION:  The Company recognizes sales upon the shipment of
goods.
 
    CASH EQUIVALENTS:  The Company considers all highly liquid investments with
a maturity of three months or less, when purchased, to be cash equivalents.
 
    INVENTORY:  Inventory is stated at the lower of cost (average cost method)
or market (see Note F). Provision is made for slow-moving, unsalable or obsolete
items.
 
    STOCK COMPENSATION PLANS:  The Company has an Incentive Compensation Plan
under which any officer or key employee is eligible to receive options as
designated by the Company's Board of Directors.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
NOTE A--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
The Company also has a Stock Option Plan for Directors under which directors are
granted nonqualified options.
 
    INTANGIBLES:  Intangibles consist primarily of product licensing and other
such costs which are capitalized and amortized on the straight line method over
the lives of the related license periods or the estimated life of the acquired
product. Accumulated amortization at December 31, 1997 and 1996 was $661,432 and
$323,829, respectively.
 
    The Company annually assesses the impairment of intangibles based on several
factors, including probable fair market value and anticipated cash flows.
 
    PROPERTY, PLANT AND EQUIPMENT:  Property, plant and equipment is stated at
cost, less accumulated depreciation. Depreciation is provided using the
straight-line method in amounts considered sufficient to amortize the cost of
the assets to operations over their estimated service lives. The average
estimated service lives of buildings and leasehold improvements, furniture and
equipment and automobiles are approximately 30, 8 and 5 years, respectively.
 
    ACCRUAL FOR CHARGEBACKS:  The Company accrues an estimate of the difference
between the gross sales price of certain products sold to wholesalers and
expected resale prices of such products under contractual arrangements with
third parties such as hospitals and group purchasing organizations at the time
of sale. As part of the Company's sales terms to wholesale customers, it agrees
to reimburse wholesalers for such differentials between wholesale prices and
contract prices. Because this accrual relates to amounts not yet collected from
the wholesalers, this accrual is carried as a reduction of accounts receivable.
 
    INTEREST CAPITALIZATION:  The Company capitalizes interest during periods of
construction of qualifying assets. For the six months ended December 31, 1996
and the year ended June 30, 1995, the Company capitalized interest costs of
$39,880 and $282,007, respectively. No interest was capitalized during the years
ended December 31, 1997 and June 30, 1996.
 
    INCOME TAXES:  The Company files a consolidated federal income tax return
with all of its subsidiaries. Deferred income taxes are provided in the
financial statements to account for the tax effects of temporary differences
resulting from reporting revenues and expenses for income tax purposes in
periods different from those used for financial reporting purposes.
 
    FAIR VALUE OF FINANCIAL INSTRUMENTS:  The Company's financial instruments
include cash, accounts receivable, accounts payable and short term debt. The
fair values of cash, accounts receivable and accounts payable approximate fair
value because of the short maturity of these instruments. The carrying amounts
of the Company's bank borrowings under its credit facility approximate fair
value because the interest rates are reset periodically to reflect current
market rates.
 
    NET INCOME PER COMMON SHARE:  In February 1997, the Financial Accounting
Standards Board ("FASB") issued SFAS No. 128, "Earnings per Share," which
requires presentation of basic and diluted earnings per share. Basic net income
per common share is based upon weighted average common shares outstanding.
Diluted net income per common share is based upon the weighted average number of
common shares outstanding, including the dilutive effect of stock options and
warrants using the treasury stock method. All prior period amounts have been
restated to conform to current reporting requirements.

NOTE B--ACQUISITION OF PASADENA RESEARCH LABORATORIES, INC.
 
    On May 31, 1996, the Company acquired Pasadena Research Laboratories, Inc.
(PRL) in a business combination accounted for as a pooling of interests. The
Company issued 1.4 million shares of its common stock in exchange for all of the
outstanding shares of PRL. PRL was merged into the operations of Taylor and the
Company was realigned into an ophthalmic division and an injectable division.
 
    The Company's financial statements for each of the two years in the period
ended June 30, 1996, as contained herein, have been restated to include the
results of PRL for all periods presented. Combined and separate results of
operations of the Company and PRL during the periods preceding the merger are

    These combined financial results include no significant adjustments to
conform the accounting policies of the two companies.
 
    In connection with the merger, the Company recorded certain charges in the
fourth quarter of the fiscal year ended June 30, 1996 for transaction costs
($109,534) and transitional costs ($567,772) associated with the realignment of
the company into two separate reporting divisions. The transaction costs include
legal, accounting and other directly related acquisition costs. Transitional
costs consist primarily of provisions for severance related costs.
 
NOTE C--REORGANIZATION OF MANUFACTURING OPERATIONS
 
    On January 15, 1992, the Company acquired Taylor Pharmacal Company in a
business combination accounted for as a pooling of interests. Taylor was a
contract manufacturer of sterile pharmaceuticals, which it produced and
delivered pursuant to contracts with third parties.
 
    As part of the acquisition of Taylor in 1992, the Company paid a finder's
fee to an affiliate of Dr. John N. Kapoor, Chairman of the Board and Chief
Executive Officer (the affiliate). This finder's fee was in the form of 250,000
shares of Company Common Stock valued at $3.50 per share. Of the total shares
issued, 125,000 were subject to forfeiture if the market price of the Company's
Common Stock did not reach at least $5.00 per share by January 15, 1996. In
August 1995, the Company, the affiliate and Dr. Kapoor entered into an agreement
under which (i) the forfeiture period was extended to January 15, 1998, (ii)
forfeiture would not occur in the event that persons unaffiliated with Dr.
Kapoor acquire beneficial ownership of more than 50% of the outstanding common
stock of the Company and (iii) Dr. Kapoor waived his right to receive $40,000
otherwise payable to him by the Company for serving as Chairman of the Board in
fiscal 1996. In May 1997 the Company extended the forfeiture period to January
15, 2000 in consideration for which Dr. Kapoor waived his right to receive
$40,000 otherwise payable to him for serving as Chairman of the Board in 1997.

NOTE D--PRODUCT ACQUISITIONS
 
    Effective December 15, 1997, the Company entered into an agreement with
Advanced Remedies, Inc. (ARI), a subsidiary of Sidmak Laboratories, Inc., to
acquire the ANDAs of two ophthalmic ointments, "Erythromycin Ophthalmic Ointment
USP, 0.5%" and "Bacitracin Zinc & Polymyxin B Sulfate Ophthalmic Ointment USP".
These products were previously purchased by the Company from third party
manufacturers. The total acquisition cost was $1.75 million, payable in seven
equal monthly installments, and is included in the accompanying Balance Sheet as
short term borrowings at December 31, 1997. The acquisition cost has been
allocated to intangibles and will be amortized over 15 years.
 
    Effective April 1, 1997, the Company entered into an agreement with
Becton-Dickinson and Company to acquire the NDAs, ANDAs and the trademarks and
trade names of three products. As part of this agreement, the Company also
acquired certain product inventory. The total acquisition cost was $4.0 million,
of which $2.5 million was paid in cash financed through the Company's revolving
line of credit and $1.5 million was paid with a non-interest bearing note
maturing in April 1999, secured by an irrevocable bank line of credit. The
Company has imputed interest on the note at an annual rate of 7.5%. The portion
of the acquisition costs allocated to intangibles amounted to $3,725,000 and
will be amortized over 18 years.
 
    Effective July 1, 1996, the Company entered into an agreement with Janssen
Pharmaceutica, Inc. (Janssen) to acquire the NDAs and the U.S. trademarks and
trade names of two injectable products, as well as certain high-speed inspection
equipment. In exchange, the Company paid Janssen $1.6 million, financed
primarily through a $1.5 million commercial credit facility. The portion of the
acquisition costs allocated to intangibles amounted to $340,000 and will be
amortized over 15 years.

NOTE M--CHANGES IN ACCOUNTING ESTIMATES
 
    The Company accrues an estimate of the difference between the gross sales
price of certain products sold to wholesalers and expected resale prices of such
products under contractual arrangements with third parties such as hospitals and
group purchasing organizations at the time of sale. This reserve is carried as a
reduction of accounts receivable. The Company evaluates the reserve balance
against actual chargebacks processed by wholesalers. Actual chargebacks
processed can vary substantially from period to period. The acquisition of two
injectable anesthesia products from Janssen Pharmaceutica in the third quarter
of 1996 resulted in a substantial increase in chargeback activity. Initial
receipt of actual chargeback requests from wholesalers was sporadic during 1996.
By year-end 1997, management felt that chargeback activity for these products
had stabilized and that sufficient data had been obtained to validate
adjustments to chargeback accrual assumptions. During the fourth quarter of the
year ended December 31, 1997, the Company revised its assumptions underlying the
reserve for chargebacks, resulting in an increase in net sales of $1,300,000.
During the fourth quarter of the year ended June 30, 1996, the Company revised
its assumptions underlying the reserve for chargebacks, resulting in a reduction
of net sales of $250,000.
 
    The Company records a reserve for slow-moving and obsolete inventory based
upon evaluation of product dating and unit sales forecasts. During the fourth
quarter of the year ended December 31, 1997, the Company increased its estimate
for unsalable inventory by approximately $900,000. During the quarters ended
March 31, June 30 and December 31, 1996, the Company increased its estimate for
unsalable inventory by approximately $300,000, $200,000 and $260,000,
respectively. These changes in estimate are reported as an increase in cost of
goods sold.

NOTE R--SUBSEQUENT EVENTS
 
    On January 21, 1998, the Company announced the purchase of the NDA,
trademark and U.S. trade name rights to Paremyd, a topical mydriatic combination
product, from Allergan. Paremyd has been off the market for all of 1997 due to a
raw material shortage. The Company will, with Allergan's assistance, move
quickly to obtain FDA approval to manufacture the product at Taylor. The total
purchase price was $700,000, with $500,000 paid in cash upon closing and
$200,000 payable upon receipt of an approved supplement from the FDA or twelve
months from closing, whichever is sooner.
 
    On January 13, 1998, the Company announced the purchase of two branded
injectable products, Sufenta and Alfenta, from Janssen Pharmaceutica, Inc. The
products are injectable opioid analgesics indicated for use in the induction and
maintenance of general anesthesia. Both are NDA products, and Alfenta remains
covered under patent. The total purchase price was $6,600,000, with $2,200,000
paid in cash upon closing and two additional payments of $2,200,000 payable on
the next anniversary of the

secured by irrevocable bank letters of credit, which are issued under the
revolving credit facility (see Note I).
 
NOTE S--RECENT ACCOUNTING PRONOUNCEMENTS
 
    In June 1997, the FASB issued SFAS No. 130, "Reporting Comprehensive
Income," which requires all items of comprehensive income be reported in a
financial statement that is displayed with the same prominence as other
financial statements. Other comprehensive income may include foreign currency
items, minimum pension liability adjustments and unrealized gains and losses on
certain investments in debt and equity securities. The accumulated balance of
other comprehensive income must be displayed separately from retained earnings
and additional paid-in capital in the equity section of a statement of financial
position. The Company adopted this accounting standard on January 1, 1998, as
required. Because the Company had no other items of comprehensive income,
reclassification of financial statements for earlier periods was not required.
 
    In June 1997, the FASB issued SFAS No. 131, "Disclosures About Segments of
an Enterprise and Related Information," which redefines how operating segments
are determined and requires disclosure of certain financial and descriptive
information about a Company's operating segments. The Company will adopt this
accounting standard as of December 31, 1998, as required. The Company expects to
continue reporting on ophthalmic and injectable segments.

ITEM 14.  INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
    Section 83 of the Business Corporation Law of Louisiana (the "BCLL") and the
Company's By-laws provide for the indemnification of directors and officers
under certain circumstances, on a case by case basis, against expenses actually
and reasonably incurred by a director or officer who was or is a party or is
threatened to be made a party to any action, suit or proceeding, whether civil,
criminal, administrative or investigative (including any action by or in the
right of the Company) by reason of the fact that he or she is or was a director,
officer, employee or agent of the Company, or is or was serving at the request
of the Company as a director, officer, employee or agent of the Company of
another entity. In accordance with the BCLL, indemnification shall be made by
the Company only as authorized in a specific case upon a determination that the
applicable standard has been met. Such determination may be made (a) by a
majority vote of a quorum of the board of directors who are disinterested, (b)
by independent counsel or (c) by the shareholders.
 
    The Company's By-laws permit the Company to procure insurance on behalf of
any current or former director, officer, employee or agent of the Company, or
person who is or was serving at the request of the Company as a director,
officer, employee or agent of the Company of another entity, against liability
asserted against him or her in any such capacity, or arising out of his or her
status as such, whether or not the Company would have the power to indemnify him
or her against such liability under the BCLL.
 
    As permitted by the BCLL, the Articles of Incorporation provide that
directors and officers of the Company shall have no personal liability to the
Company or its stockholders for monetary damages for breach of fiduciary duty as
a director or officer, except for (i) any breach of the director's or officer's
duty of loyalty to the Company or its shareholders, (ii) acts or omissions not
in good faith or which involve intentional misconduct or knowing violation of
law, (iii) authorizing illegal dividends or redemptions or (iv) any transaction
from which the director or officer derived an improper personal benefit.
 
ITEM 15.  RECENT SALES OF UNREGISTERED SECURITIES
 
    On December 13, 1997, the John N. Kapoor Trust dated September 20, 1989 (the
"Kapoor Trust"), of which John N. Kapoor, the Chairman and Chief Executive
Officer of the Company, is sole trustee and beneficiary, purchased 1,000,000
shares of Common Stock. The price per share was $2.00 per share and
 
                                      II-1
<PAGE>
the aggregate purchase price was $2.0 million. The shares were purchased in
connection with the exercise of a warrant originally issued to the Kapoor Trust
on September 3, 1992.
 
    In connection with the acquisition of PRL on May 31, 1996, the Company
issued to the Benjamin Family Trust, the Yankoff Revocable Living Trust and the
Gencarella Revocable Living Trust, as selling shareholders of PRL, 1,400,000
shares of Common Stock as consideration for all of the outstanding shares of
PRL. The conversion rate was 14,814.815 shares of Common Stock for each share of
PRL stock outstanding at the time of conversion.
 
    As to all such transactions described above, an exemption is claimed under
Section 4(2) of the Securities Act.

ITEM 17.  UNDERTAKINGS
 
    (a) Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the provisions described in Item 14, or otherwise, the
registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
Securities Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Securities
Act and will be governed by the final adjudication of such issue.
 
    (b) The undersigned Registrant hereby undertakes that:
 
                                      II-3
<PAGE>
        (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
    the form of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or
    (4) or 497(h) under the Securities Act shall be deemed to be part of this
    Registration Statement as of the time it was declared effective.
 
        (2) For the purposes 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.

                                   SIGNATURES

2.   AMOUNT AND TERMS OF CREDIT

          2.1  ADVANCES. (a)  Subject to the terms and conditions of this 
Agreement, the Lender agrees to make advances (the "ADVANCE(S)") to the 
Borrowers, from time to time from the date of this Agreement until the 
Termination Date, at such times and in such amounts as the Borrowers may 
request, not to exceed in the aggregate at any one time outstanding the 
difference of (i) the Commitment, MINUS (ii) the Letter of Credit Obligation. 
Until all amounts outstanding in respect of the Loans shall become due and 
payable on the Termination Date, Borrowers may from time to time borrow, 
repay and reborrow under this SECTION 2.1(a).  Each Advance to a Borrower 
shall be made on notice by such Borrower to the Lender at its principal 
banking office at 50 South LaSalle Street, Chicago, Illinois  60675, given no 
later than 11:00 a.m. (Chicago time) on (a) the Business Day of the proposed 
Advance or, (b) in the case of a request for an Advance that is a LIBOR Loan, 
two (2) Business Days prior to the date of the proposed Advance; PROVIDED, 
HOWEVER, that any Advance requested as a LIBOR Loan shall be in a minimum 
amount of $250,000 and integral multiples of $50,000 in excess of such 
amount.  Each such notice (a "NOTICE OF ADVANCE") shall be substantially in 
the form of EXHIBIT A hereto, specifying therein the requested date, the 
amount and type of such Advance, and such other information as may be 
required by Lender and shall be given in writing (by telecopy or overnight 
courier) or by telephone confirmed immediately in writing if requested by the 

                                       18
<PAGE>

Lender.  Lender shall be entitled to rely upon, and shall be fully protected 
under this Agreement in relying upon, any Notice of Advance believed by 
Lender to be genuine and to assume that each Person executing and delivering 
the same was duly authorized unless the responsible individual acting thereon 
for Lender shall have, at the time of reliance thereon, actual knowledge to 
the contrary.

               (b)  Borrowers shall execute and deliver to the Lender a note 
to evidence the Loans, such note to be in the principal amount of the 
Commitment, dated the date hereof and substantially in the form of EXHIBIT B 
hereto (the "NOTE").  The Note shall represent the joint and several 
obligation of each Borrower to pay the amount of the Commitment or, if less, 
the aggregate unpaid principal amount of all Advances made by the Lender to 
Borrowers and all other obligations with interest thereon as prescribed in 
SECTION 2.5.  The date and amount of each Advance and each payment of 
principal with respect thereto shall be recorded on the books and records of 
the Lender, which books and records shall constitute PRIMA FACIE evidence of 
the accuracy of the information therein recorded.  The entire unpaid balance 
of the Loans shall be immediately due and payable on the Termination Date.

               (c)  Each Borrower hereby designates Akorn as its sole agent 
for the purposes of issuing Notices of Advances, requesting an issuance of a 
Letter of Credit, selecting interest rate options and receiving notices and 
consents hereunder.

          2.2  LETTERS OF CREDIT.

               (a) REQUESTS.  By delivering to Lender an Issuance Request
     substantially in the form of SCHEDULE A hereto, on or before 3:00 p.m.,
     Chicago time, Borrowers may request, from time to time prior to the
     Termination Date and on not less than two Business Days' notice, that the
     Lender issue a standby letter of credit, and for such purposes described in
     the Issuance Request (as used herein, the term "issue" when referring to
     Letters of Credit shall include any increase in the amount of or extension
     of the term of any Letter of Credit).  The Stated Amount of any Letter of
     Credit requested to be issued pursuant to such Issuance Request shall be
     denominated in U.S. dollars.  Each Letter of Credit shall by its terms:

               (i)  be issued in a Stated Amount which, together with all Letter
     of Credit Obligations and the Loans, in the aggregate does not exceed (or
     would not exceed) the Commitment;

               (ii)  be stated to expire on a date (its "STATED EXPIRY DATE") no
     later than the Termination Date; and

               (iii) on or prior to its Stated Expiry Date:

                                       19
<PAGE>

                    (A)  terminate immediately upon notice to the Lender from
          the beneficiary thereunder that all obligations covered thereby have
          been terminated, paid, or otherwise satisfied in full, or

                    (B) reduce in part immediately and to the extent the
          beneficiary thereunder has notified the Lender thereof that the
          obligations covered thereby have been paid or otherwise satisfied in
          part.

By delivery to the Lender of an Issuance Request at least two Business Days 
prior to the Stated Expiry Date of any Letter of Credit, Borrowers may 
request the Lender to extend the Stated Expiry Date of such Letter of Credit 
for an additional period not to exceed the period ending on the Termination 
Date.

          (b)  ISSUANCES AND EXTENSIONS.  Subject to the terms and conditions 
of this Agreement, the Lender shall issue Letters of Credit, and extend the 
Stated Expiry Dates of outstanding Letters of Credit, in accordance with the 
Issuance Requests made therefor.  If the Issuance Request consists of, or is 
supplemented by, the Lender's standard letter of credit application form, the 
terms of such application shall apply with respect to such Letter of Credit, 
but only to the extent such terms are not inconsistent with the provisions 
hereof.

          (c)  FEES AND EXPENSES.  Borrowers agree to pay to the Lender, (i) 
in respect of each standby Letter of Credit, a fee equal to 1.00% per annum 
(calculated from and including the date of issuance (or date of renewal or 
extension, if any) thereto to the Stated Expiry Date thereof) on the Stated 
Amount of each such Letter of Credit, payable in advance on the last Business 
Day of each Fiscal Quarter and on the Termination Date, and (ii)upon demand 
from time to time, Lender's standard issuance, administrative, operating and 
other fees and charges in effect from time to time in connection with the 
fronting, issuance, maintenance, modification (if any) and administration of 
each Letter of Credit.

          (d)  DISBURSEMENTS.  The Lender will notify Akorn promptly of the 
presentment for payment of any Letter of Credit, together with notice of the 
date (the "DISBURSEMENT DATE") such payment shall be made.  Subject to the 
terms and provisions of such Letter of Credit, the Lender shall make such 
payment to the beneficiary (or its designee) of such Letter of Credit.  Prior 
to 12:00 noon, Chicago time, on the Disbursement Date, Borrower will 
reimburse the Lender for all amounts which it has disbursed under such Letter 
of Credit.  To the extent the Lender is not reimbursed in full in accordance 
with this subsection, Borrower's Reimbursement Obligation shall accrue 
interest at a fluctuating rate determined by reference to the Prime Rate, 
plus a margin of 2% per annum, payable on demand.  In the event the Lender is 
not 

                                       20
<PAGE>

reimbursed by Borrower on the Disbursement Date, or if the Lender must for 
any reason return or disgorge such reimbursement, the Lender shall fund the 
Reimbursement Obligation therefor by making Loans as provided in SECTION 2.1 
(Borrowers being deemed to have given a timely request therefor for such 
amount); PROVIDED, HOWEVER, for the purpose of determining the availability 
of the Advances immediately prior to giving effect to the application of the 
proceeds of such Loans, such Reimbursement Obligations shall be deemed not to 
be outstanding at such time.

          (e)  REIMBURSEMENT.  Borrowers' obligation (a "REIMBURSEMENT 
OBLIGATION") under subsection (d) of this SECTION 2.2 to reimburse the Lender 
with respect to each Disbursement (as defined below) (including interest 
thereon) shall be absolute and unconditional under any and all circumstances 
and irrespective of any set-off, counterclaim, or defense to payment which 
Borrowers may have or have had against the Lender or any beneficiary of a 
Letter of Credit, including any defense based upon the occurrence of any 
Event of Default or Default, any draft, demand, or certificate, or other 
document presented under a Letter of Credit proving to be forged, fraudulent, 
invalid, or insufficient, the failure of any Disbursement to conform to the 
terms of the applicable Letter of Credit (if, in the Lender's good faith 
opinion, such Disbursement is determined to be appropriate) or any 
non-application or misapplication by the beneficiary of the proceeds of such 
Disbursement, or the legality, validity, form, regularity, or enforceability 
of such Letter of Credit.  "DISBURSEMENT" means any payment made under a 
Letter of Credit by the Lender to the beneficiary thereunder.

          (f)  DEEMED DISBURSEMENTS.  Upon the occurrence and during the 
continuation of any Event of Default, an amount equal to that portion of 
Letter of Credit Obligations attributable to outstanding and undrawn Letters 
of Credit shall, at the option of the Lender, and without demand upon or 
notice to Akorn, be deemed to have been paid or disbursed by the Lender under 
such Letters of Credit (notwithstanding that such amount may not in fact have 
been so paid or disbursed), and, upon notification by the Lender to Akorn of 
its obligations under this subsection, Borrowers shall be immediately 
obligated to reimburse the Lender the amount deemed to have been so paid or 
disbursed by the Lender.  Any amounts so received by the Lender from 
Borrowers pursuant to this subsection shall be held as collateral security 
for the repayment of Borrowers' obligations in connection with the Letters of 
Credit.  At any time when such Letters of Credit shall terminate and all 
Reimbursement Obligations to the Lender are either terminated or paid or 
reimbursed to the Lender in full, the obligations of Borrowers under this 
subsection shall be reduced accordingly (subject, however, to reinstatement 
in the event any payment in respect of such Letters of Credit is recovered in 
any manner from any Lender), and, if no Event of Default shall be continuing, 
the Lender will return to Borrowers the excess, if any, of 

                                       21
<PAGE>

          (i)  the aggregate amount deposited by Borrowers with the Lender and
     not theretofore applied by the Lender to any Reimbursement Obligation; over

          (ii) the aggregate amount of all Reimbursement Obligations to the
     Lender pursuant to this subsection, as so adjusted.

At such time when all Events of Default shall have been cured or waived, the
Lender shall return to Borrower all amounts then on deposit with the Lender
pursuant to this subsection.  All amounts on deposit pursuant to this subsection
shall, until their application to any Reimbursement Obligation or their return
to Borrowers, as the case may be, bear interest at the daily average Federal
Funds Rate (without taking into account the Applicable Percentage) from time to
time in effect (net of the costs of any reserve requirements, in respect of
amounts on deposit pursuant to this Section, pursuant to Federal Reserve Board
Regulation D), which interest shall be held by the Lender as additional
collateral security for the repayment of the Letter of Credit obligations in
connection with the Letters of Credit issued by the Lender.

          (g)  NATURE OF REIMBURSEMENT OBLIGATIONS.  Borrowers shall assume all
risks of the acts, omissions, or misuse of any Letter of Credit by the
beneficiary thereof.  The Lender (except to the extent of its own gross
negligence or wilful misconduct) shall not be responsible for:

          (i)  the form, validity, sufficiency, accuracy, genuineness, or legal
     effect of any Letter of Credit or any document submitted by any party in
     connection with the application for an issuance of a Letter of Credit, even
     if it should in fact prove to be in any or all respects invalid,
     insufficient, inaccurate, fraudulent, or forged;

          (ii)  the form, validity, sufficiency, accuracy, genuineness, or legal
     effect of any instrument transferring or assigning or purporting to
     transfer or assign a Letter of Credit or the rights or benefits thereunder
     or proceeds thereof in whole or in part, which may prove to be invalid or
     ineffective for any reason;

          (iii)  failure of the beneficiary to comply fully with conditions
     required in order to demand payment under a Letter of Credit;

          (iv)   errors, omissions, interruptions, or delays in transmission or
     delivery of any messages, by mail, cable, telegraph, telex or otherwise; or

          (v)    any loss or delay in the transmission or otherwise of any
     document or draft required in order to make a

                                       22
<PAGE>

     Disbursement under a Letter of Credit or of the proceeds thereof.

None of the foregoing shall affect, impair, or prevent the vesting of any of the
rights or powers granted the Lender hereunder.

          2.3  PREPAYMENT, COMMITMENT REDUCTION.  Borrowers shall have the right
at any time on three (3) days' prior written notice to the Lender to voluntarily
prepay all or part of the Loans and permanently reduce or terminate the
Commitment, and no prepayment fee, premium or penalty shall be payable in
connection with any such voluntary prepayment, except LIBOR funding breakage
costs in accordance with SECTION 2.10(b).  Within three (3) days from a closing
date of a real estate financing by the Borrowers, the Loans shall be prepaid and
the Commitment shall be permanently reduced by an amount equal to 75% of the
difference of (i) the net proceeds of such financing, MINUS (ii) $1,000,000, in
accordance with the terms of this SECTION 2.3.  Upon any such prepayment and
permanent reduction or termination of the Commitment, Borrowers' right to
receive Advances shall simultaneously terminate or be permanently reduced, as
the case may be.

          2.4  USE OF PROCEEDS.  Borrowers shall utilize the proceeds of
Advances for working capital financing for the Borrowers and funding for
acquisitions and other general corporate purposes of the Borrowers.

          2.5  INTEREST ON LOANS.  

               (a) Borrowers shall pay interest to Lender, in arrears on each
applicable Interest Payment Date, based on the amounts outstanding from time to
time under the Loan, at a rate equal to (i) the Prime Rate, (ii) the applicable
LIBOR Rate or (iii) the Federal Funds Rate.

               (b) If any payment on the Loans becomes due and payable on a day
other than a Business Day, the maturity thereof shall be extended to the next
succeeding Business Day (except as set forth in the definition of LIBOR Period)
and, with respect to payments of principal, interest thereon shall be payable at
the then applicable rate during such extension.

               (c)  All computations of interest shall be made by the Lender on
the basis of a three hundred and sixty (360) day year, in each case for the
actual number of days occurring in the period for which such interest is
payable.  The Prime Rate and the Federal Funds Rate shall be determined each day
based upon the Prime Rate and the Federal Funds Rate, respectively, as in effect
each day.  Each determination by the Lender of an interest rate hereunder shall
be conclusive and binding for all purposes, absent manifest error or bad faith.

                                       23
<PAGE>

               (d)  So long as any Event of Default shall have occurred and be
continuing, and after written notice from the Lender to Akorn, the interest
rates applicable to the Loans and any other Obligations shall be increased by
two percent (2%) per annum above the rate of interest otherwise applicable
hereunder ("DEFAULT RATE").

               (e)  Notwithstanding anything to the contrary set forth in 
this SECTION 2.5, if, at any time until payment in full of all of the 
Obligations, the rate of interest payable hereunder exceeds the highest rate 
of interest permissible under any law which a court of competent jurisdiction 
shall, in a final determination, deem applicable hereto (the "MAXIMUM LAWFUL 
RATE"), then in such event and so long as the Maximum Lawful Rate would be so 
exceeded, the rate of interest payable hereunder shall be equal to the 
Maximum Lawful Rate; PROVIDED, HOWEVER, that if at any time thereafter the 
rate of interest payable hereunder is less than the Maximum Lawful Rate, 
Borrowers shall continue to pay interest hereunder at the Maximum Lawful Rate 
until such time as the total interest received by Lender from the making of 
such advances hereunder is equal to the total interest which would have been 
received had the interest rate payable hereunder been (but for the operation 
of this paragraph) the interest rate payable since the Closing Date as 
otherwise provided in this Agreement. Thereafter, the interest rate payable 
hereunder shall be the rate of interest provided in SECTIONS 2.5(b) through 
(d) of this Agreement, unless and until the rate of interest again exceeds 
the Maximum Lawful Rate, in which event this paragraph shall again apply.  In 
no event shall the total interest received by Lender pursuant to the terms 
hereof exceed the amount which Lender could lawfully have received had the 
interest due hereunder been calculated for the full term hereof at the 
Maximum Lawful Rate.  In the event the Maximum Lawful Rate is calculated 
pursuant to this paragraph, such interest shall be calculated at a daily rate 
equal to the Maximum Lawful Rate divided by the number of days in the year in 
which such calculation is made.  In the event that a court of competent 
jurisdiction, notwithstanding the provisions of this SECTION 2.5(e), shall 
make a final determination that Lender has received interest hereunder or 
under any of the other Loan Documents in excess of the Maximum Lawful Rate, 
Lender shall, to the extent permitted by applicable law, promptly apply such 
excess first to any interest due and not yet paid hereunder in respect of the 
Loans, then to the outstanding principal of the Loans, then to Fees and any 
other unpaid Obligations and thereafter shall refund any excess to Borrowers 
or as a court of competent jurisdiction may otherwise order. 

          2.6  FEES.  As compensation for Lender's costs and risks in making the
Loan available to Borrowers, Borrowers agree to pay to Lender, in arrears, on
the last Business Day of each month prior to the Termination Date and on the
Termination Date, a fee for Borrowers' non-use of available funds (the "NON-USE
FEE") in an amount equal to one quarter of one percent (0.25%) per annum

                                       24
<PAGE>

(calculated on the basis of a 360 day year for actual days elapsed) of the
difference between the respective daily averages of (i) the Commitment (as it
may be adjusted from time to time hereunder) and (ii) the sum of (x) the amount
of the Loan outstanding, PLUS (y) the Letter of Credit Obligations during the
period for which the Non-Use Fee is due.

          2.7  CHARGING OF ACCOUNTS. The Borrowers hereby authorize the Lender,
and the Lender may, in its sole and absolute discretion charge to the Borrowers
at any time all or any portion of any of the Obligations then due and owing (and
interest, if any, thereon) including but not limited to any Fees and other costs
and expenses of the Lender for which the Borrowers are liable pursuant to the
terms of this Agreement or any other Loan Document, by charging Akorn's demand
deposit account or any other bank account with the Lender; PROVIDED, HOWEVER
that the provisions of this SECTION 2.7 shall not affect the Borrowers'
obligation to pay when due all amounts payable by the Borrowers under this
Agreement, the Note or any other Loan Document, whether or not there are
sufficient funds therefor in the demand deposit account or any other bank
account of Akorn with the Lender.

          2.8  APPLICATION AND ALLOCATION OF PAYMENTS.  Lender is authorized to,
and at its option may, make or cause to be made Advances on behalf of Borrowers
for payment of all Fees, expenses, Charges, costs, principal, interest, or other
Obligations owing by Borrower under this Agreement or any of the other Loan
Documents if and to the extent any such Borrower fails to promptly pay any such
amounts as and when due, even if such Advance would cause total Advances to
exceed the Loan Commitment.  At Lender's option and to the extent permitted by
law, any advances so made shall be deemed Advances constituting part of the Loan
hereunder.  Following the occurrence and during the continuance of an Event of
Default, Borrowers hereby irrevocably waive the right to direct the application
of any and all payments at any time or times hereafter received from or on
behalf of any such Borrower, and each Borrower hereby irrevocably agrees that
Lender shall have the continuing exclusive right to apply any and all such
payments against the then due and payable Obligations of Borrowers and in
repayment of the Loan as Lender may deem advisable notwithstanding any previous
entry by Lender upon the Loan Account or any other books and records.  In the
absence of a specific determination by Lender with respect thereto, the same
shall be applied in the following order:  (i) to then due and payable interest
payments on the Loans; (ii) to principal payments on the Loan; (iii) to then due
and payable Fees and expenses; (iv) to then due and payable Obligations other
than Fees, expenses and interest and principal payments; and (v) to all other
then due and payable Obligations.  

          2.9  LOAN ACCOUNT AND ACCOUNTING.  Lender shall maintain a loan
account (the "LOAN ACCOUNT") on its books to record:(a) all Advances, (b) all
payments made by Borrowers and (c) all other 

                                       25
<PAGE>

appropriate debits and credits as provided in this Agreement with respect to 
the Loans or any other Obligations. All entries in the Loan Account shall be 
made in accordance with Lender's customary accounting practices as in effect 
from time to time.  Borrowers shall pay all Obligations as such amounts 
become due or are declared due pursuant to the terms of this Agreement.

          The balance in the Loan Account shall be presumptive evidence of 
the amounts due and owing to Lender by Borrower; PROVIDED, THAT, any failure 
to so record or any error in so recording shall not limit or otherwise affect 
Borrowers' obligations to pay the Obligations.  Any accounting provided by 
Lender to Akorn regarding the Loan Account shall (absent manifest error) be 
deemed final, binding and conclusive upon Borrowers in all respects as to all 
matters reflected therein, unless Akorn, within thirty (30) days after the 
date any such accounting is rendered, shall notify Lender in writing of any 
objection which Borrowers may have to any such accounting, describing the 
basis for such objection with specificity.  In that event, only those items 
expressly objected to in such notice shall be deemed to be disputed by 
Borrowers.  Lender's determination, based upon the facts available, of any 
item objected to by Akorn in such notice shall (absent manifest error) be 
final, binding and conclusive on Borrowers.

          2.10 INDEMNITY.(a) Each Borrower shall indemnify and hold each of 
Lender and its Affiliates, and each of Lender's and its Affiliates' 
respective officers, directors, employees, attorneys, agents and 
representatives (each an "INDEMNIFIED PERSON") harmless from and against any 
and all suits, actions, proceedings, claims, damages, losses, liabilities and 
expenses (including attorneys' fees and disbursements and other costs of 
investigation or defense, including those incurred upon any appeal) which may 
be instituted or asserted against or incurred by any such Indemnified Person 
as the result of credit having been extended under this Agreement and the 
other Loan Documents or in connection with or arising out of the transactions 
contemplated hereunder and thereunder or any actions or failures to act in 
connection therewith, including any and all Environmental Liabilities and 
Costs; PROVIDED, THAT no Borrower shall be liable for any indemnification to 
such Indemnified Person to the extent that any such suit, action, proceeding, 
claim, damage, loss, liability or expense results solely from such 
Indemnified Person's gross negligence or willful misconduct, as finally 
determined by a court of competent jurisdiction after exhaustion of all 
available appeals.  NEITHER LENDER NOR ANY OTHER INDEMNIFIED PERSON SHALL BE 
RESPONSIBLE OR LIABLE TO ANY OTHER PARTY HERETO, ANY SUCCESSOR, ASSIGNEE OR 
THIRD PARTY BENEFICIARY OF SUCH PERSON OR ANY OTHER PERSON ASSERTING CLAIMS 
DERIVATIVELY THROUGH SUCH PARTY, FOR INDIRECT, PUNITIVE, EXEMPLARY OR 
CONSEQUENTIAL DAMAGES WHICH MAY BE ALLEGED AS A RESULT OF CREDIT HAVING BEEN 
EXTENDED OR TERMINATED UNDER THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS.

                                       26
<PAGE>

               (b)  Borrowers understand that in connection with Lender's 
arranging to provide the LIBOR Rate interest option, Lender may enter into 
funding arrangements with third parties ("FUNDING ARRANGEMENTS") on terms and 
conditions which could result in losses to Lender if such LIBOR Rate funds do 
not remain outstanding at the interest rates provided herein for the entire 
LIBOR Period with respect to which the LIBOR Rate has been fixed.  
Consequently, in order to induce Lender to provide such options on the terms 
provided herein and in consideration of Lender entering into such Funding 
Arrangements from time to time, if any LIBOR Loans are repaid in whole or in 
part prior to the last day of any such LIBOR Period therefor, whether such 
repayment is made pursuant to any provision of this Agreement or any other 
Loan Document or is the result of acceleration, by operation of law or 
otherwise, Borrowers shall indemnify and hold harmless Lender from and 
against and in respect of any and all losses, costs and expenses resulting 
from, or arising out of or imposed upon or incurred by Lender by reason of 
the liquidation or reemployment of funds acquired or committed to be acquired 
by Lender to fund such LIBOR Loans, pursuant to the Funding Arrangements.  
The amount of any losses, costs or expenses resulting in an obligation of 
Borrowers to make a payment pursuant to the foregoing sentence shall not 
include any losses attributable to lost profit to Lender but shall represent 
the excess, if any, of (A) Lender's cost of borrowing the LIBOR Rate funds, 
pursuant to the Funding Arrangements over (B) the return to Lender on its 
reinvestment of such funds; PROVIDED, HOWEVER, that if Lender terminates any 
Funding Arrangements in respect of the LIBOR Loans, the amount of such 
losses, costs and expenses shall include the cost to Lender of such 
termination.  In reinvesting any funds borrowed by Lender pursuant to the 
Funding Arrangements, Lender shall take into consideration the remaining 
maturity of such borrowings. As promptly as practicable under the 
circumstances, Lender shall provide Akorn with its written calculation of all 
amounts payable pursuant to the next preceding sentence, and such calculation 
shall be binding on the parties hereto unless Akorn shall object thereto in 
writing within ten (10) Business Days of receipt thereof.

          2.11 ACCESS. (a) Each Borrower shall provide full access during 
normal business hours, from time to time upon one (1) Business Day's prior 
notice, to Lender and any of its officers, employees and agents, as 
frequently as Lender determines, in its reasonable discretion, to be 
appropriate (unless a Default or Event of Default shall have occurred and be 
continuing, in which event Lender and its officers, employees, designees, 
agents and representatives shall have access at any and all times and without 
any advance notice), to the properties, facilities, books, and records of 
Borrowers and their Subsidiaries, to the Collateral, to the accountants of 
Borrowers and the Subsidiaries thereof and to the work papers of such 
accountants, and in addition, (x) while any Default or Event of Default shall 
have occurred and be continuing, (y) at any time for purposes of inspection, 
audit or verification 

                                       27
<PAGE>

of Accounts, or (z) upon the consent of Akorn, to such Borrower's suppliers, 
customers, advisors and employees (including officers). Without limiting the 
generality of the foregoing, each Borrower shall (i) permit Lender, and any 
of its officers, employees, agents and representatives, to inspect, audit and 
make extracts from all of such Borrower's and its Subsidiaries' records, 
files and books of account and (ii) permit Lender, and any of its officers, 
employees, agents and representatives, to inspect, review and evaluate the 
Accounts at such Borrower's and its Subsidiaries' locations and at premises 
not owned by or leased to such Borrower or any Subsidiary of such Borrower.  
Each Borrower shall make available to Lender and its counsel, as quickly as 
is possible under the circumstances, originals or copies of all books, 
records, board minutes, contracts, insurance policies, environmental audits, 
business plans, files, financial statements (actual and pro forma), filings 
with federal, state and local regulatory agencies, and other instruments and 
documents which Lender may request.  Each Borrower shall deliver any document 
or instrument necessary for Lender, as it may from time to time request, to 
obtain records from any service bureau or other Person which maintains 
records for such Borrower, and shall maintain duplicate records or supporting 
documentation on media, including computer tapes and discs owned by such 
Borrower.  Borrowers shall instruct their certified public accountants to 
make available to Lender such information and records as Lender may request.

          (b)  A fee of $500 per day per individual or Lender's then standard 
rate, whichever is greater, (plus all reasonable out-of-pocket costs and 
expenses) in connection with Lender's field examinations permitted under 
SECTION 2.11(a) above and SECTION 5(g) of the Security Agreement shall be 
paid promptly by Borrowers in connection with each field audit conducted 
after the Closing Date.

          2.12 TAXES. (a)  Any and all payments by any Borrower hereunder or 
under the Note shall be made, in accordance with this SECTION 2.12, free and 
clear of and without deduction for any and all present or future Taxes.  If 
any Borrower shall be required by law to deduct any Taxes from or in respect 
of any sum payable hereunder or under the Note, (i) the sum payable shall be 
increased as much as shall be necessary so that after making all required 
deductions (including deductions applicable to additional sums payable under 
this SECTION 2.12) Lender shall receive an amount equal to the sum Lender 
would have received had no such deductions been made, (ii) such Borrower 
shall make such deductions, and (iii) such Borrower shall pay the full amount 
deducted to the relevant taxing or other authority in accordance with 
applicable law.

               (b)  Borrowers shall indemnify and pay, within ten (10) days of
demand therefor, Lender for the full amount of Taxes (including any Taxes
imposed by any jurisdiction on amounts payable under this SECTION 2.12) paid by
Lender and any liability (including penalties, interest and expenses) arising
therefrom or 

                                       28
<PAGE>

with respect thereto, whether or not such Taxes were correctly or legally 
asserted.

          2.13 CAPITAL ADEQUACY; INCREASED COSTS; ILLEGALITY. (a)  In the 
event that Lender shall have determined that the adoption after the date 
hereof of any law, treaty, governmental (or quasi-governmental) rule, 
regulation, guideline or order regarding capital adequacy, reserve 
requirements or similar requirements or compliance by Lender with any request 
or directive regarding capital adequacy, reserve requirements or similar 
requirements (whether or not having the force of law and whether or not 
failure to comply therewith would be unlawful) from any central bank or 
governmental agency or body having jurisdiction does or would have the effect 
of increasing the amount of capital, reserves or other funds required to be 
maintained by Lender and thereby reducing the rate of return on Lender's 
capital as a consequence of its obligations hereunder, then Borrowers shall 
from time to time within fifteen (15) days after notice and demand on Akorn 
by Lender (together with the certificate referred to in the next sentence) 
pay to Lender additional amounts sufficient to compensate Lender for such 
reduction.  A certificate as to the amount of such cost and showing the basis 
of the computation of such cost submitted by Lender to Borrowers shall, 
absent manifest error, be final, conclusive and binding for all purposes.

               (b)  If, due to either (i) the introduction of or any change 
in or in the interpretation of any law or regulation or (ii) the compliance 
with any guideline or request from any central bank or other Governmental 
Authority (whether or not having the force of law), including, without 
limitation, any requirement that Lender hold reserves with respect to the 
Loan, or the Loan Commitment, there shall be any increase in the cost to 
Lender of agreeing to make or making, funding or maintaining of any Loan, 
then Borrowers shall from time to time, upon demand by Lender, pay to Lender 
for the account of Lender additional amounts sufficient to compensate Lender 
for such increased cost.  A certificate as to the amount of such increased 
cost, submitted to Akorn by Lender, shall be conclusive and binding on 
Borrowers for all purposes, absent manifest error.  Lender agrees that, as 
promptly as practicable after it becomes aware of any circumstances referred 
to in CLAUSE (i) or (ii) above which would result in any such increased cost 
to Lender, it shall, to the extent not inconsistent with Lender's internal 
policies of general application, use reasonable commercial efforts to 
minimize costs and expenses incurred by it and payable to it by Borrowers 
pursuant to this SECTION 2.13 (b).

               (c)  Notwithstanding anything to the contrary contained herein,
if the introduction of or any change in or in the interpretation of any law or
regulation shall make it unlawful, or any central bank or other Governmental
Authority shall assert that it is unlawful, for Lender to agree to make or to
make or to 

                                       29
<PAGE>

continue to fund or maintain any LIBOR Loan, then, unless Lender is able to 
agree to make or to make or to continue to fund or to maintain such LIBOR 
Loan at another branch or office of Lender without, in Lender's opinion, 
adversely affecting it or its Loans or the income obtained therefrom, on 
notice thereof and demand therefor by Lender to Borrowers, (i) the obligation 
of Lender to agree to make or to make or to continue to fund or maintain 
LIBOR Loans shall terminate and (ii) Borrowers shall forthwith prepay in full 
all outstanding LIBOR Loans, together with interest accrued thereon, UNLESS 
Borrowers, within five (5) Business Days after the delivery of such notice 
and demand, convert all such Loans into a Loan bearing interest based on the 
Prime Rate.

               (d)  Upon Lender obtaining actual knowledge of the occurrence 
of any of the events set forth in this SECTION 2.13, Lender shall promptly 
notify Akorn of the occurrence of such event.  Borrowers shall have the right 
within five (5) days of receipt of such notice to convert any outstanding 
LIBOR Loans to Prime Rate Loans.

          2.14 CONVERSION AND CONTINUATION ELECTIONS.

          (a)  Borrowers may, upon irrevocable written notice (or telephonic
     notice promptly confirmed in writing) to Lender in accordance with SECTION
     2.14(b):

               (i)  elect, as of any Business Day, in the case of Floating Rate
          Loans, or as of the last day of the applicable LIBOR Period, in the
          case of LIBOR Loans, to convert any such Loans (or any part thereof in
          an aggregate minimum amount of $50,000, or integral multiples of
          $10,000 in excess thereof, in the case of Floating Rate Loans, and
          $250,000, or integral multiples of $50,000 in excess thereof, in the
          case of LIBOR Loans) into Loans of any other type; or

               (ii) elect as of the last day of the applicable LIBOR Period, to
          continue any LIBOR Loans having LIBOR Periods expiring on such day (or
          any part thereof in an amount not less than $250,000, or that is in an
          integral multiple of $50,000 in excess thereof);

     PROVIDED, that if at any time the aggregate amount of LIBOR Loans in
     respect of any borrowing is reduced, by payment, prepayment, or conversion
     of part thereof to be less than $250,000, such LIBOR Loans shall
     automatically convert into Floating Rate Loans, and on and after such date
     the right of Borrower to continue such LIBOR Loans as, and convert such
     LIBOR Loans into, LIBOR Loans shall terminate.

          (b)  Borrower shall deliver a Notice of Conversion/Continuation to be
     received by Lender not later 

                                       30
<PAGE>

     than 10:00 a.m. (Chicago  time) at least (i) two Business Days in advance 
     of the Conversion/ Continuation Date, if the Loans are to be converted
     into or continued as LIBOR Loans and (ii) on the date of the Conversion/
     Continuation Date, if the Loans are to be converted into Floating Rate
     Loans, specifying:

               (i)  the proposed Conversion/Continuation Date;

               (ii)  the aggregate amount of Loans to be converted or continued;

               (iii)  the type of Loans resulting from the proposed conversion
          or continuation; and

               (iv)  other than in the case of conversions into Floating Rate
          Loans, the duration of the requested LIBOR Period.

          (c)  If upon the expiration of any LIBOR Period applicable to LIBOR
     Loans, Borrowers have failed to select a new LIBOR Period to be applicable
     to such LIBOR Loans by the time specified in SECTION 2.14(b), or if any
     Event of Default then exists, Borrowers shall be deemed to have elected to
     convert such LIBOR Loans into Federal Funds Rate Loans effective as of the
     expiration date of such LIBOR Period.

3.   CONDITIONS PRECEDENT

          3.1  CONDITIONS TO THE INITIAL ADVANCE.

<PAGE>

          (iii)     No event shall have occurred and be continuing, or would

Advance or the incurrence of any Letter of Credit Obligation shall be deemed 
to constitute, as of the date of such request or acceptance, a representation 
and warranty by Borrowers that the conditions in this SECTION 3.2 have been 
satisfied.

4.   REPRESENTATIONS AND WARRANTIES

          To induce Lender to make the Loans and to incur any Letter of 
Credit Obligation, Borrowers make the following representations and 
warranties to Lender, each and all of which shall survive the execution and 
delivery of this Agreement:

          4.1  CORPORATE EXISTENCE; COMPLIANCE WITH LAW.  Each Borrower and 
each Subsidiary thereof (i) is a corporation duly organized, validly existing 
and in good standing under the laws of its jurisdiction of incorporation and 
has been duly qualified to conduct business and is in good standing in each 
other jurisdiction where its ownership or lease of property or the conduct of 
its business requires such qualifications; (ii) has the requisite corporate 
power and authority and the legal right to own, pledge, mortgage or otherwise 
encumber and operate its properties, to lease the property it operates under 
lease and to conduct its business as now, heretofore and proposed to be 
conducted; (iii) has all licenses, permits, consents or approvals from or by, 
and has made all filings with, and has given all notices to, all Governmental 
Authorities, including but not limited to, FDA and DEA, having jurisdiction, 
to the extent required for such ownership, operation and conduct; (iv) is in 
compliance with its certificate or articles of incorporation and by-laws; and 
(v) is in compliance with all applicable provisions of law, including but not 
limited to, the Federal Food, Drug and Cosmetic Act, the Controlled 
Substances Act and other United States federal statutes and regulations, 
issued by the FDA and DEA.

          4.2  EXECUTIVE OFFICES.  The current location of each Borrower's 
chief executive office and principal place of business is set forth in 
SCHEDULE 4.2 and, as of the Closing Date, none of such locations have changed 
within the past three (3) months.

          4.3  CORPORATE POWER AUTHORIZATION, ENFORCEABLE OBLIGATIONS.  The 
execution, delivery and performance by each Borrower of the Loan Documents 
and all instruments and documents to be delivered by such Person and the 
creation of all Liens provided for therein: (i) are within such Person's 
corporate power; (ii) have been duly authorized by all necessary or proper 
corporate and shareholder action; (iii) are not in contravention of any 
provision 

                                       33
<PAGE>

of such Person's certificate or articles or incorporation or bylaws; (iv) 
will not violate any law or regulation, or any order or decree of any court 
or governmental instrumentality; (v) will not conflict with or result in the 
breach or termination of, constitute a default under or accelerate any 
performance required by, any indenture, mortgage, deed of trust, lease, 
agreement or other Instrument to which such Person is a party or by which 
such Person or any of its property is bound; (vi) will not result in the 
creation or imposition of any Lien upon any of the property of such Person 
other than those in favor of Lender pursuant to the Loan Documents; and (vii) 
do not require the consent or approval of any Governmental Authority or any 
other Person.  On or prior to the Closing Date, each of the Loan Documents 
shall have been duly executed and delivered for the benefit of or on behalf 
of each Borrower and each Loan Document shall then constitute a legal, valid 
and binding obligation of such Borrower, enforceable against it in accordance 
with its terms, except as enforceability may be limited by bankruptcy, 
insolvency or other similar laws affecting the rights of creditors generally 
or by application of general principles of equity.

          4.4  FINANCIAL STATEMENTS.  All financial statements (the 
"FINANCIAL STATEMENTS"), of the Borrowers and their respective Subsidiaries  
which have been delivered to the Lender, have been prepared in accordance 
with GAAP consistently applied throughout the periods involved (except as 
disclosed therein and except, with respect to unaudited financial statements, 
for the absence of footnotes and normal year-end audit adjustments) and do 
present fairly in all material respects the financial condition of the 
corporations covered thereby as at the dates thereof and the results of their 
operations for the periods then ended.

          4.5  MATERIAL ADVERSE EFFECT.  Since September 30, 1997, none of 
the Borrowers and no Subsidiary thereof has incurred any obligations, 
contingent liabilities, or liabilities for Charges, long-term leases or 
unusual forward or long-term commitments which are not reflected in the 
Financial Statements of Borrowers and their Subsidiaries and which could,

Material Adverse Effect has occurred between September 30, 1997 and the 
Closing Date.   

          4.6  TITLE AND LIENS.  All Collateral is and will continue to be

party is in default, under or with respect to any material contract, 
agreement, lease or other Instrument to which it is a party.

          4.8  LABOR MATTERS.  No strikes or other labor disputes against any 
Borrower or any Subsidiary thereof are pending or, to any Borrower's 
knowledge, threatened.  Hours worked by and payment made to employees of each 
Borrower and the Subsidiaries thereof have not been, to any Borrower's 
knowledge, in violation of the Fair Labor Standards Act or any other 
applicable federal, state, local or foreign law dealing with such matters.  
All payments due from such Borrower or any Subsidiary thereof on account of 
employee health and welfare insurance have been paid or accrued as a 
liability on the books of Borrowers.  Except as set forth in SCHEDULE 4.8, 
there are no material employment, consulting or management agreements 
covering any management employee or Affiliate of any Borrower or any 
Subsidiary thereof.  A true and complete copy of each such material agreement

the Borrowers and none of the Subsidiaries thereof have any obligation under 
any collective bargaining agreement, management agreement, consulting 
agreement or any employment agreement.  There is no organizing activity 
involving any Borrower or any Subsidiary thereof pending or, to any 
Borrower's knowledge, threatened by any labor union or group of employees.

against any Borrower or any Subsidiary thereof pending or threatened to be

any Subsidiary thereof of any individual.

Except as set forth in SCHEDULE 4.9, none of the Borrowers (i) has any 
Subsidiaries, (ii) is engaged in any joint venture or partnership with any 
other Person and (iii) is an Affiliate of any other Person.  Except as set 
forth in SCHEDULE 4.9, there are no outstanding rights to purchase, options, 
warrants or similar rights or agreements pursuant to which any Borrower may 
be required to issue or sell any Stock or other equity security of any 
Subsidiary. 

          4.10 GOVERNMENT REGULATION.  None of the Borrowers and no Subsidiary
thereof is an "investment company" or an "affiliated 

                                       35
<PAGE>

person" of, or "promoter" or "principal underwriter" for, an "investment 
company," as such terms are defined in the Investment Company Act of 1940, as 
amended.  None of the Borrowers and no Subsidiary thereof is subject to 
regulation under the Public Utility Holding Company Act of 1935, the Federal 
Power Act, or any other federal or state statute that restricts or limits its 
ability to incur Indebtedness or to perform its obligations hereunder, and 
the making of the Advances by Lender, the incurrence of any Letter of Credit 
Obligation, the application of the proceeds and repayment thereof by such 
Borrower or such Subsidiary and the consummation of the transactions 
contemplated by this Agreement and the other Loan Documents will not violate 
any provision of any such statute or any rule, regulation or order issued by 
the Securities and Exchange Commission.

          4.11 MARGIN REGULATIONS.  None of the Borrowers and no Subsidiary 
thereof is engaged, nor will it engage, principally or as one of its 
important activities, in the business of extending credit for the purpose of 
"purchasing" or "carrying" any "margin security" as such terms are defined in 
Regulation U or G of the Board of Governors of the Federal Reserve System 
(the "FEDERAL RESERVE BOARD") as now and from time to time hereafter in 
effect (such securities being referred to herein as "MARGIN STOCK").  None of 
the Borrowers and no Subsidiary thereof owns any Margin Stock, and the 
proceeds of the Advances will not be used, directly or indirectly, for the 
purpose of purchasing or carrying any Margin Stock, for the purpose of 
reducing or retiring any indebtedness which was originally incurred to 
purchase or carry any Margin Stock or for any other purpose which might cause 
any of the loans or other extensions of credit under this Agreement to be 
considered a "purpose credit" within the meaning of Regulation G, T, U or X 
of the Federal Reserve Board.

          4.12 TAXES.  All federal, state, local and foreign tax returns, 
reports and statements, including, but not limited to, information returns 
required to be filed by each Borrower or any Subsidiary thereof, have been 
filed with the appropriate Governmental Authority and all Charges and other 
impositions shown thereon to be due and payable have been paid prior to the 
date on which any fine, penalty, interest or late charge may be added thereto 
for nonpayment thereof (or any such fine, penalty, interest, late charge or 
loss has been paid), and each Borrower and each Subsidiary thereof has paid 
when due and payable all Charges required to be paid by it, except such 
Taxes, if any, as are being contested in good faith and by appropriate 
proceedings and as to which such reserves or other appropriate provisions as 
may be required by GAAP have been maintained.  Proper and accurate amounts 
have been withheld by each Borrower or each Subsidiary thereof from its 
respective employees for all periods in full and complete compliance with the 
tax, social security and unemployment withholding provisions of applicable 
federal, state, local and 

                                       36
<PAGE>

foreign law and such withholdings have been timely paid to the respective 
Governmental Authorities.

          4.13 ERISA. (a)  SCHEDULE 4.13 lists all Plans maintained or 
contributed to by any Borrower or any Subsidiary thereof and all Qualified 
Plans maintained or contributed to by any ERISA Affiliate, and separately 
identifies the Title IV Plans, Multiemployer Plans, any multiple employer 
plans subject to Section 4064 of ERISA, unfunded Pension Plans, Welfare Plans 
and Retiree Welfare Plans.  Each Qualified Plan has been determined by the 
IRS to qualify under Section 401 of the IRC, and the trusts created 
thereunder have been determined to be exempt from tax under the provisions of 
Section 501 of the IRC, and to the best knowledge of each Borrower nothing 
has occurred which would cause the loss of such qualification or tax-exempt 
status.  To any Borrower's knowledge, each Plan is in compliance with the 
applicable provisions of ERISA and the IRC, including the filing of reports 
required under the IRC or ERISA, and with respect to each Plan, other than a 
Qualified Plan, all required contributions and benefits have been paid in 
accordance with the provisions of each such Plan. None of the Borrowers and 
no Subsidiary or ERISA Affiliate thereof, with respect to any Qualified Plan, 
has failed to make any contribution or pay any amount due as required by 
Section 412 of the IRC or Section 302 of ERISA or the terms of any such Plan. 
 With respect to all Retiree Welfare Plans, the present value of future 
anticipated expenses pursuant to the latest actuarial projections of 
liabilities does not exceed $0; with respect to Pension Plans, other than 
Qualified Plans, the present value of the liabilities for current 
participants thereunder using PBGC interest assumptions does not exceed $0.  
None of the Borrowers and no Subsidiary or ERISA Affiliate thereof has 
engaged in a prohibited transaction, as defined in Section 4975 of the IRC or 
Section 406 of ERISA, in connection with any Plan, which would subject any 
Borrower or any Subsidiary thereof (after giving effect to any exemption) to 
a material tax on prohibited transactions imposed by Section 4975 of the IRC 
or any other material liability.

          (b)  Except as set forth in SCHEDULE 4.13: (i) no Title IV Plan has 
any Unfunded Pension Liability; (ii) no ERISA Event or event described in 
Section 4062(e) of ERISA with respect to any Title IV Plan has occurred or is 
reasonably expected to occur; (iii) there are no pending, or to the knowledge 
of any Borrower, threatened claims, actions or lawsuits (other than claims 
for benefits in the normal course), asserted or instituted against (x) any 
Plan or its assets, (y) any fiduciary with respect to any Plan or (z) any 
Borrower or any Subsidiary or ERISA Affiliate thereof with respect to any 
Plan; (iv) none of the Borrowers and no Subsidiary or ERISA Affiliate thereof 
has incurred or reasonably expects to incur any withdrawal liability (and no 
event has occurred which, with the giving of notice under Section 4219 of 
ERISA, would result in such liability) under Section 4201 of ERISA as a 
result of a complete or partial withdrawal from a 

                                       37
<PAGE>

Multiemployer Plan; (v) within the last five years neither any Borrower nor 
any Subsidiary or ERISA Affiliate thereof has engaged in a transaction which 
resulted in a Title IV Plan with Unfunded Liabilities being transferred 
outside of the "controlled group" (within the meaning of Section 4001(a)(14) 
of ERISA) of any such entity; (vi) no Plan which is a Retiree Welfare Plan 
provides for continuing benefits or coverage for any participant or any 
beneficiary of a participant after such participant's termination of 
employment (except as may be required by Section 4980B of the IRC and at the 
sole expense of the participant or the beneficiary of the participant); (vii) 
each Borrower and each Subsidiary and ERISA Affiliate thereof have complied 
with the notice and continuation coverage requirements of Section 4980B of 
the IRC and the regulations thereunder except where the failure to comply 
could not have or result in any Material Adverse Effect; and (viii) no 
liability under any Plan has been funded, nor has such obligation been 
satisfied, with the purchase of a contract from an insurance company that is 
not rated AAA by the Standard & Poor's Corporation or the equivalent by 
another nationally recognized rating agency.

          4.14 NO LITIGATION.  No action, claim or proceeding is now pending 
or, to the knowledge of any Borrower, threatened against such Borrower or any 
Subsidiary thereof, before any court, board, commission, agency or 
instrumentality of any federal, state, local or foreign government or of any 
agency or subdivision thereof, or before any arbitrator or panel of 
arbitrators, (i) which challenges such Borrower's or such Subsidiary's right 
or power to enter into or perform any of its obligations under the Loan 
Documents, or the validity or enforceability of any Loan Document or any 
action taken thereunder, or (ii) which, if determined adversely, would have 
or result in a Material Adverse Effect, nor to the best knowledge of any 
Borrower does a state of facts exist which is reasonably likely to give rise 
to such proceedings.

          4.15 PATENTS, TRADEMARKS, COPYRIGHTS AND LICENSES.  Except as 
otherwise set forth in SCHEDULE 4.15, each Borrower owns all material 
licenses, patents, patent applications, copyrights, service marks, 
trademarks, trademark applications, and trade names necessary to continue to 
conduct its business as heretofore conducted by it or proposed to be 
conducted by it, each of which is listed, together with Copyright Office or 
Patent and Trademark Office application or registration numbers, where 
applicable, on SCHEDULE 4.15. SCHEDULE 4.15 also lists all tradenames or 
other names under which any Borrower conducts business.  To the best of 
Borrower's knowledge, neither the conduct of each Borrower's business nor the 
conduct of any of its Subsidiary's business infringes upon any intellectual 
property right of any other Person.

          4.16 FULL DISCLOSURE.  No information contained in this Agreement, 
any of the other Loan Documents, the Projections, the Financials, the 
Collateral Reports or any written statement

<PAGE>

furnished by or on behalf of any Borrowers or any Subsidiary thereof pursuant 
to the terms of this Agreement, which has previously been delivered to 
Lender, contains any untrue statement of a material fact or omits to state a 
material fact necessary to make the statements contained herein or therein 
not misleading in light of the circumstances under which they were made.  The 
Liens granted to Lender pursuant to the Collateral Documents will at the 
Closing Date be fully perfected first priority Liens in and to the Collateral 
described therein, subject only to Liens set forth in SCHEDULE 4.6 and 
Permitted Liens.  

          4.17 HAZARDOUS MATERIALS.  Except as set forth in SCHEDULE 4.17, 
(i) the real estate (the "REAL ESTATE") owned by the Borrowers and their 
Subsidiaries is free of contamination from any Hazardous Material, or (ii) to 
any Borrower's knowledge, the Real Estate leased by the Borrowers or their 
Subsidiaries is free of contamination from any Hazardous Material.  In 
addition, SCHEDULE 4.17 discloses all material environmental liabilities of 
any Borrower or any Subsidiary thereof of which any Borrower has knowledge 
(i) related to noncompliance with the Environmental Laws, or (ii) associated 
with the Real Estate.  None of the Borrowers and no Subsidiary thereof has 
caused or suffered to occur any Release with respect to any Hazardous 
Material at, under, above or upon any real property which it owns or leases.  
None of the Borrowers and no Subsidiary thereof is involved in operations 
which are likely to result in the imposition of any Lien on its assets or any 
material liability on such Borrower or Subsidiary thereof under any 
Environmental Law, and none of the Borrowers and no Subsidiary thereof has 
permitted any tenant or occupant of such premises to engage in any such 
activity.  Borrowers have provided to Lender copies of all existing 
environmental reports, reviews and audits and all written information 
pertaining to actual or potential Environmental Liabilities and Costs, in 
each case relating to any of the Borrowers or any of the Subsidiaries thereof.

          4.18 INSURANCE POLICIES. SCHEDULE 4.18 lists all insurance of any 
nature maintained for current occurrences by any Borrower or any Subsidiary 
thereof, as well as a summary of the terms of such insurance.

banks and other financial institutions at which any of the Borrowers or any 
Subsidiary thereof maintains deposits and/or other accounts, including any 
disbursement accounts, and such Schedule correctly identifies the name,

account is held, a description of the purpose of the account, and the 
complete account number.

          4.20 CUSTOMER AND TRADE RELATIONS.  There exists no actual or
threatened termination or cancellation of, or any material adverse modification
or change in: (a) the business 

                                       39
<PAGE>

relationship of Borrowers with any  customer or group of customers which has 
resulted in or is reasonably likely to result in a Material Adverse Effect; 
or (b) the business relationship of any Borrower or any Subsidiary thereof 
with any supplier material to the operations of such Borrower or such 
Subsidiary which has resulted in or is reasonably likely to result in a 
Material Adverse Effect.

          4.21 INDEBTEDNESS.  As of the Closing Date, except for the Loans 
and the Letter of Credit, and as set forth in SCHEDULE 7.3, none of the 
Borrowers and no Subsidiary thereof has any Indebtedness or has granted any 
security interest to any Person other than Lender and First National Bank of 
Commerce.

          (b)  Each Borrower may in good faith contest, by appropriate

<PAGE>

          6.5  LITIGATION.  Each Borrower shall notify Lender in writing, 
promptly upon learning thereof, of any litigation commenced or threatened 
against such Borrower or any Subsidiary thereof and of the institution 
against it of any suit or administrative proceeding that (a) seeks damages in 
excess of $500,000 or (b) seeks injunctive relief.

          6.6  INSURANCE.  (a)  Borrowers shall, at their sole cost and 
expense, maintain the policies of insurance described on SCHEDULE 4.18 in 
form and with insurers rated AA or better by Bests.  Such policies shall be 
in such amounts as are set forth in SCHEDULE 4.18.  Borrowers shall notify 
Lender promptly of any occurrence causing a material loss or decline in value 
of any real or personal property and the estimated (or actual, if available) 
amount of such loss or decline.  So long as any Event of Default shall have 
occurred and be continuing or if the casualty loss exceeds $500,000: each 
Borrower hereby directs all present and future insurers under its "All Risk" 
policies of insurance to pay all proceeds payable thereunder directly to 
Lender and irrevocably makes, constitutes and appoints Lender (and all 
officers, employees or agents designated by Lender) as such Borrower's true 
and lawful agent and attorney-in-fact for the purpose of making, settling and 
adjusting claims under such "All Risk" policies of insurance and endorsing 
the name of such Borrower on any check or other item of payment for the 
proceeds of such "All Risk" policies of insurance.  In the event any Borrower 
at any time or times hereafter shall fail to obtain or maintain any of the 
policies of insurance required above or to pay any premium in whole or in 
part relating thereto, Lender, without waiving or releasing any Obligations 
or Default or Event of Default hereunder, may at any time or times thereafter 
(but shall not be obligated to) obtain and maintain such policies of 
insurance and pay such premiums and take any other action with respect 
thereto which Lender deems advisable.  All sums so disbursed, including 
attorneys, fees, court costs and other charges related thereto, shall be 
payable, on demand, by Borrowers to Lender and shall be additional 
Obligations hereunder secured by the Collateral, PROVIDED, THAT, if and to 
the extent Borrowers fail to promptly pay any of such sums upon demand 
therefor, Lender is authorized to, and at its option may, make or cause to be 
made Advances on behalf of Borrowers for payment thereof.

          (b)  Lender reserves the right at any time, upon any change in any
Borrower's risk profile (including, without limitation, any change in the
product mix maintained by any Borrower or any laws affecting the potential
liability of such Borrower), to require additional forms and limits of insurance
to, in Lender's reasonable opinion, adequately protect Lender's interests in all
or any portion of the Collateral and to ensure that each Borrower and each
Subsidiary thereof is protected by insurance in amounts and with coverage
customary for its industry.  If requested by Lender, each Borrower shall deliver
to Lender from 

                                       43
<PAGE>

time to time a report of a reputable insurance broker, satisfactory to 
Lender, with respect to its insurance policies.

          (c)  Borrowers shall deliver to Lender endorsements (i) to all "All 
Risk" and business interruption insurance naming Lender as loss payee, and 
(ii) to all general liability and other liability policies naming Lender as 
additional insured.

          (d)  The loss, if any, under any property insurance required to be 
carried by this SECTION 6.6 shall be adjusted with the insurance companies or 
otherwise collected, including the filing of appropriate proceedings by 
Borrowers or their Subsidiaries, subject to the reasonable approval of the 
Lender in the case of claims in excess of $500,000.  If the proceeds payable 
under any policy of property insurance are $500,000 or less, Borrowers or 
their Subsidiaries shall have the right to use such proceeds to repair or 
replace the damaged or destroyed property, provided that a Default or an 
Event of Default shall not have occurred and be continuing at the time the 
proceeds are paid.  

          6.7  COMPLIANCE WITH LAWS.  Each Borrower shall, and shall cause 
each Subsidiary thereof to, comply in all material respects with all federal, 
state and local laws and regulations applicable to it, including but not 
limited to, (i) the Federal Food, Drug and Cosmetic Act, the Controlled 
Substances Act and other United States federal statutes and regulations, 
issued by FDA and DEA, and (ii) those relating to licensing, ERISA and labor 
matters.

          6.8  SUPPLEMENTAL DISCLOSURE. On the request of Lender (in the 
event that such information is not otherwise delivered by Borrowers to Lender 
pursuant to this Agreement), so long as there are Obligations outstanding 
hereunder, but not more frequently than quarterly absent the occurrence and 
continuance of a Default or an Event of Default, Borrowers will supplement 
each schedule or representation herein with respect to any matter hereafter 
arising which, if existing or occurring at the date of this Agreement, would 
have been required to be set forth or described in such schedule or as an

7.   NEGATIVE COVENANTS

without the prior written consent of Lender, from and after the date hereof 
until the Termination Date:

          7.1  MERGERS, SUBSIDIARIES, ETC.  No Borrower shall, or shall permit
any Subsidiary to:

          (a)  be a party to any merger or consolidation;

          (b)  except in the normal course of its business, sell, transfer,

     expenses incurred to consummate such acquisition) and (ii) there is no
     Event of Default or Default after giving effect to such acquisition.

leased or otherwise disposed of by the Borrowers and their Subsidiaries (other
than in the normal course of business) during the same Fiscal Year, exceeds 10%
of the Borrowers' consolidated total assets determined as of the end of the
immediately preceding Fiscal Year.  As used in the preceding sentence, the term
"value" shall mean, with respect to any asset disposed of, the greater of such
asset's book or fair market value as of the date of disposition, with "book
value" being the value of such asset as would appear immediately prior to such
disposition on a balance sheet of the owner of such asset prepared in accordance

in this Agreement, no Borrower shall, or shall cause or permit any Subsidiary
thereof to, make any investment in, or make or accrue loans or advances of money
to any Person, through the direct or indirect lending of money, holding of
securities or otherwise;  PROVIDED that so long as no Default or Event of
Default shall have occurred or be continuing, Borrowers may make 

                                       46

of America, each having combined capital, surplus and undivided profits of

thirty (30) days from the date of creation thereof with commercial banks or 
savings banks or savings and loan associations each having membership in the 
Federal Deposit Insurance Corporation and in amounts not exceeding the 
maximum amounts of insurance thereunder, except that in the case of time 
deposits and certificates of deposit maintained with The Northern Trust 
Company or its successors so long as such successors meet the criteria in

thereof shall be provided by Lender to Akorn.

applicable law, (v) existing Indebtedness set forth in SCHEDULE 7.3 and

refinanced,(vi) any financing secured by any real estate owned by the 
Borrowers and their Subsidiaries, and (vii) the unsecured financing by a 
seller of product lines to Borrowers.

          7.4  EMPLOYEE LOANS AND AFFILIATE TRANSACTIONS. (a) No Borrower 
shall, or shall cause or permit any Subsidiary thereof to, enter into or be a 
party to any transaction with an Affiliate except in the ordinary course of, 
and pursuant to the reasonable requirements of, such Borrower's or such 
Subsidiary's business and upon fair and reasonable terms that are fully 
disclosed to Lender in advance and are no less favorable to such Borrower or 
such Subsidiary than would be obtained in a comparable arm's length 
transaction with a Person not an Affiliate of such Borrower or such 
Subsidiary.  All such transactions existing as of the date hereof are 
described on SCHEDULE 7.4(a).

have or result in a Material Adverse Effect, (ii) make any change in its 
capital structure as described on SCHEDULE 4.9, or (iii) amend its 
certificate or articles of incorporation or bylaws in a manner which would

Subsidiary or businesses reasonably related thereto.

incurred for the benefit of any Borrower or such Subsidiary if the primary 
obligation is expressly permitted by this Agreement.

assets), (iv) Liens in connection with any financing secured by any real

or, all of the Obligations shall become immediately due and payable without 
declaration, notice or demand by Lender.

exemption laws.  Each of the Borrowers acknowledges that it has been advised 
by counsel of its choice with respect to this Agreement, the other Loan 
Documents and the transactions evidenced by this Agreement and the other Loan 
Documents.

9.   SUCCESSORS AND ASSIGNS

          9.1  SUCCESSORS AND ASSIGNS.   This Agreement and the other Loan 
Documents shall be binding on and shall inure to the benefit of Borrowers, 
Lender and their respective successors and assigns, except as otherwise 
provided herein or therein.  None of the Borrowers may assign, transfer, 
hypothecate or otherwise convey its rights, benefits, obligations or duties 
hereunder or under any of the other Loan Documents without the prior express 
written consent of Lender.  Any such purported assignment, transfer, 
hypothecation or other conveyance by any Borrower without the prior express 
written consent of Lender shall be void.  The terms and provisions of this 
Agreement are for the purpose of defining the relative rights and obligations 
of Borrowers and Lender with respect to the transactions contemplated hereby 
and there shall be no third party beneficiaries of any of the terms and 
provisions of this Agreement or any of the other Loan Documents.

10.  MISCELLANEOUS

          10.1 SETOFF.  In addition to any rights now or hereafter granted 
under applicable law and not by way of limitation of any such rights, upon 
the occurrence and during the continuance of any Event of Default, Lender and 
each holder of any Term Note or Note is hereby authorized at any time or from 
time to time, without notice to any Borrower or to any other Person, any such 
notice being hereby expressly waived, to set off and to appropriate and to 
apply any and all balances held by it at any of its offices for the account 
of Borrowers (regardless of whether such balances are then due to Borrowers) 
and any other properties or assets any time held or owing by Lender or such 
holder to or for the credit or for the account of Borrowers against and on 
account of any of the Obligations which are not paid when due.

          10.2 COMPLETE AGREEMENT; MODIFICATION OF AGREEMENT.  The Loan 
Documents constitute the complete agreement between the parties with respect 
to the subject matter thereof and may not be modified, altered or amended 
except as set forth in SECTION 10.3 below.  Any letter of interest or 
commitment letter and/or fee letter between Borrowers and Lender or any of 
their respective affiliates, predating this Agreement and relating to a 
financing of substantially similar form, purpose or effect shall be 
superseded by this Agreement.

          10.3 AMENDMENTS AND WAIVERS.(a) Except as otherwise provided 
herein, no amendment, modification, termination or waiver of any provision of 
this Agreement or any of the other Loan 

                                       55
<PAGE>

Documents or consent to any departure by any Borrower or any of its 
Subsidiaries therefrom shall in any event be effective unless the same shall 
be in writing and signed by Lender and Borrowers.

          (b)  Each amendment, modification, termination or waiver shall be 
effective only in the specific instance and for the specific purpose for 
which it was given.  No amendment, modification, termination or waiver shall 
be required for Lender to take additional Collateral pursuant to any Loan 
Document. No notice to or demand on any Borrower in any case shall entitle 
any Borrower to any other or further notice or demand in similar or other 
circumstances.  

          10.4 FEES AND EXPENSES.    Borrowers shall reimburse Lender for all 
reasonable out-of-pocket expenses, incurred in connection with the 
preparation of the Loan Documents (including the reasonable fees and expenses 
of all of its special loan counsel, advisors, consultants and auditors 
retained in connection with the Loan Documents and the transactions 
contemplated thereby and advice in connection therewith).  In addition, 
Borrowers shall reimburse Lender for all fees, costs and expenses, including 
the fees, costs and expenses of counsel or other advisors (including 
environmental and management consultants) for advice, assistance, or other 
representation in connection with:

               (a)  any amendment, modification or waiver of, or consent with 
respect to, any of the Loan Documents or, advice in connection with the 
administration of the loans made pursuant hereto or its rights hereunder or 
thereunder;

               (b)  any litigation, contest, dispute, suit, proceeding or 
action (whether instituted by Lender, any Borrower or any other Person) in 
any way relating to the Collateral, any of the Loan Documents or any other 
agreement to be executed or delivered in connection therewith or herewith, 
whether as party, witness, or otherwise, including any litigation, contest, 
dispute, suit, case, proceeding or action, and any appeal or review thereof, 
in connection with a case commenced by or against any or all of Borrowers or 
any other Person that may be obligated to Lender by virtue of the Loan 
Documents;

               (c)  any attempt to enforce any rights of Lender against any 
or all of Borrowers or any other Person that may be obligated to Lender by 
virtue of any of the Loan Documents; and

               (d)  efforts to verify, protect, evaluate, assess, appraise, 
collect, sell, liquidate or otherwise dispose of any of the Collateral;

including, without limitation, all reasonable attorneys' and other professional
and service providers' fees arising from such services, including those in
connection with any appellate 

                                       56
<PAGE>

proceedings; and all reasonable expenses, costs, charges and other fees 
incurred by such counsel and others in any way or respect arising in 
connection with or relating to any of the events or actions described in this 
SECTION 10.4 shall be payable, on demand, by Borrowers to Lender. Without 
limiting the generality of the foregoing, such expenses, costs, charges and 
fees may include: fees, costs and expenses of accountants, environmental 
advisors, appraisers, investment bankers, management and other consultants 
and paralegals; court costs and expenses; photocopying and duplication 
expenses; court reporter fees, costs and expenses; long distance telephone 
charges; air express charges; telegram charges; secretarial overtime charges; 
and reasonable expenses for travel, lodging and food paid or incurred in 
connection with the performance of such legal or other advisory services.

          10.5 NO WAIVER.  Lender's failure at any time or times, to require 
strict performance by Borrowers of any provision of this Agreement and any of 
the other Loan Documents shall not waive, affect or diminish any right of 
Lender thereafter to demand strict compliance and performance therewith.  Any 
suspension or waiver of an Event of Default under this Agreement or any of 
the other Loan Documents shall not suspend, waive or affect any other Event 
of Default under this Agreement and any of the other Loan Documents whether 
the same is prior or subsequent thereto and whether of the same or of a 
different type.  None of the undertakings, agreements, warranties, covenants 
and representations of any Borrower contained in this Agreement or any of the 
other Loan Documents and no Default or Event of Default by any Borrower under 
this Agreement and no defaults by any Borrower under any of the other Loan 
Documents shall be deemed to have been suspended or waived by Lender unless 
such waiver or suspension is by an Instrument in writing signed by an officer 
of or other authorized employee of Lender and directed to Borrowers 
specifying such suspension or waiver.

          10.6 REMEDIES.  Lender's rights and remedies under this Agreement 
shall be cumulative and nonexclusive of any other rights and remedies which 
Lender may have under any other agreement, including the other Loan 
Documents, by operation of law or otherwise.  Recourse to the Collateral 
shall not be required.

          10.7 SURVIVAL OF OBLIGATIONS UPON TERMINATION OF FINANCING 
AGREEMENTS. Except as otherwise expressly provided for in the Loan Documents, 
no termination or cancellation (regardless of cause or procedure) of any 
financing arrangement under this Agreement shall in any way affect or impair 
the obligations, duties and liabilities of Borrowers or the rights of Lender 
relating to any unpaid portion of the Loan or any other Obligation, due or 
not due, liquidated, contingent or unliquidated or any transaction or event 
occurring prior to such termination, or any transaction or event, the 
performance of which is required after the Termination Date.  Except as 
otherwise expressly provided herein or in any other Loan Document, all 
undertakings, agreements, covenants, 

                                       57
<PAGE>

warranties and representations of or binding upon Borrowers, and all rights 
of Lender, all as contained in the Loan Documents shall not terminate or 
expire, but rather shall survive such termination or cancellation and shall 
continue in full force and effect until such time as all of the Obligations 
have been paid in full in accordance with the terms of the agreements 
creating such Obligations.

          10.8 SEVERABILITY.  Wherever possible, each provision of this 
Agreement and the other Loan Documents shall be interpreted in such a manner 
as to be effective and valid under applicable law, but if any provision of 
this Agreement shall be prohibited by or invalid under applicable law, such 
provision shall be ineffective to the extent of such prohibition or 
invalidity, without invalidating the remainder of such provision or the 
remaining provisions of this Agreement.

          10.9 CONFLICT OF TERMS.  Except as otherwise provided in this 
Agreement or any of the other Loan Documents by specific reference to the 
applicable provisions of this Agreement, if any provision contained in this 
Agreement is in conflict with, or inconsistent with, any provision in any of 
the other Loan Documents, the provision contained in this Agreement shall 
govern and control.

          10.10 AUTHORIZED SIGNATURE.  Until Lender shall be notified by 
Akorn to the contrary, the signature upon any document or Instrument 
delivered pursuant hereto of an officer of any Borrower listed on SCHEDULE 
10.10 shall bind such Borrower and be deemed to be the act of such Borrower 
affixed pursuant to and in accordance with resolutions duly adopted by such 
Borrower's Board of Directors.

          10.11 GOVERNING LAW.  EXCEPT AS OTHERWISE EXPRESSLY PROVIDED IN
ANY OF THE LOAN DOCUMENTS, IN ALL RESPECTS, INCLUDING ALL MATTERS OF
CONSTRUCTION, VALIDITY AND PERFORMANCE, THIS AGREEMENT AND THE OBLIGATIONS
ARISING HEREUNDER SHALL BE GOVERNED BY, AND CONSTRUED AND ENFORCED IN ACCORDANCE
WITH, THE INTERNAL LAWS (WITHOUT REGARD TO CONFLICT OF LAW PROVISIONS) OF THE
STATE OF ILLINOIS APPLICABLE TO CONTRACTS MADE AND PERFORMED IN SUCH STATE, AND
ANY APPLICABLE LAWS OF THE UNITED STATES OF AMERICA.  EACH BORROWER HEREBY
CONSENTS AND AGREES THAT THE STATE OR FEDERAL COURTS LOCATED IN COOK COUNTY,
CITY OF CHICAGO, ILLINOIS, SHALL HAVE EXCLUSIVE JURISDICTION TO HEAR AND
DETERMINE ANY CLAIMS OR DISPUTES BETWEEN BORROWER AND LENDER PERTAINING TO THIS
AGREEMENT OR ANY OF THE OTHER LOAN DOCUMENTS OR TO ANY MATTER ARISING OUT OF OR
RELATING TO THIS AGREEMENT OR ANY OF THE OTHER LOAN DOCUMENTS, PROVIDED, THAT
LENDER AND BORROWERS ACKNOWLEDGE THAT ANY APPEALS FROM THOSE COURTS MAY HAVE TO
BE HEARD BY A COURT LOCATED OUTSIDE OF COOK COUNTY, CITY OF CHICAGO, ILLINOIS
AND, PROVIDED, THAT NOTHING IN THIS AGREEMENT SHALL BE DEEMED OR OPERATE TO
PRECLUDE LENDER FROM BRINGING SUIT OR TAKING OTHER LEGAL ACTION IN ANY OTHER

                                       58
<PAGE>

JURISDICTION TO REALIZE ON THE COLLATERAL OR ANY OTHER SECURITY FOR THE 
OBLIGATIONS, OR TO ENFORCE A JUDGMENT OR OTHER COURT ORDER IN FAVOR OF 
LENDER. EACH BORROWER EXPRESSLY SUBMITS AND CONSENTS IN ADVANCE TO SUCH 
JURISDICTION IN ANY ACTION OR SUIT COMMENCED IN ANY SUCH COURT, AND BORROWER 
HEREBY WAIVES ANY OBJECTION WHICH SUCH BORROWER MAY HAVE BASED UPON LACK OF 
PERSONAL JURISDICTION, IMPROPER VENUE OR FORUM NON CONVENIENS AND HEREBY 
CONSENTS TO THE GRANTING OF SUCH LEGAL OR EQUITABLE RELIEF AS IS DEEMED 
APPROPRIATE BY SUCH COURT.  EACH BORROWER HEREBY WAIVES PERSONAL SERVICE OF 
THE SUMMONS, COMPLAINT AND OTHER PROCESS ISSUED IN ANY SUCH ACTION OR SUIT 
AND AGREES THAT SERVICE OF SUCH SUMMONS, COMPLAINTS AND OTHER PROCESS MAY BE 
MADE BY REGISTERED OR CERTIFIED MAIL ADDRESSED TO SUCH BORROWER AT THE 
ADDRESS SET FORTH IN SCHEDULE D OF THIS AGREEMENT AND THAT SERVICE SO MADE 
SHALL BE DEEMED COMPLETED UPON THE EARLIER OF SUCH BORROWER'S ACTUAL RECEIPT 
THEREOF OR THREE (3) DAYS AFTER DEPOSIT IN THE U.S. MAILS, PROPER POSTAGE 
PREPAID.

          10.12     NOTICES.  Except as otherwise provided herein, whenever 
it is provided herein that any notice, demand, request, consent, approval, 
declaration or other communication shall or may be given to or served upon 
either of the parties by the other party, or whenever either of the parties 
desires to give or serve upon the other party any communication with respect 
to this Agreement, each such notice, demand, request, consent, approval, 
declaration or other communication shall be in writing and shall be deemed to

of any notice required hereunder may be waived in writing by the party 
entitled to receive such notice.  Failure or delay in delivering copies of 
any notice, demand, request, consent, approval, declaration or other 
communication to any Person (other than Borrowers or Lender) designated on

          10.13     SECTION TITLES.  The Section titles and Table of Contents 
contained in this Agreement are and shall be without substantive meaning or 
content of any kind whatsoever and are not a part of the agreement between 
the parties hereto.

          10.14     COUNTERPARTS.  This Agreement may be executed in any 
number of separate counterparts, each of which shall collectively and 
separately constitute one agreement.

          10.15     WAIVER OF JURY TRIAL.  BECAUSE DISPUTES ARISING IN 
CONNECTION WITH COMPLEX FINANCIAL TRANSACTIONS ARE MOST QUICKLY AND 
ECONOMICALLY RESOLVED BY AN EXPERIENCED AND EXPERT PERSON AND THE PARTIES 
WISH APPLICABLE STATE AND FEDERAL LAWS TO APPLY (RATHER THAN ARBITRATION 
RULES), THE PARTIES DESIRE THAT THEIR DISPUTES BE RESOLVED BY A JUDGE 
APPLYING SUCH APPLICABLE LAWS. THEREFORE, TO ACHIEVE THE BEST COMBINATION OF 
THE BENEFITS OF THE JUDICIAL SYSTEM AND OF ARBITRATION, THE PARTIES HERETO 
WAIVE ALL RIGHT TO TRIAL BY 

                                       60
<PAGE>

JURY IN ANY ACTION, SUIT, OR PROCEEDING BROUGHT TO RESOLVE ANY DISPUTE, 
WHETHER SOUNDING IN CONTRACT, TORT OR OTHERWISE, AMONG LENDER AND BORROWERS 
ARISING OUT OF, CONNECTED WITH, RELATED TO, OR INCIDENTAL TO THE RELATIONSHIP 
ESTABLISHED AMONG THEM IN CONNECTION WITH, THIS AGREEMENT OR ANY OF THE OTHER 
LOAN DOCUMENTS OR THE TRANSACTIONS RELATED THERETO.

          10.16     REINSTATEMENT. This Agreement shall remain in full force 
and effect and continue to be effective should any petition be filed by or 
against any Borrower for liquidation or reorganization, should any Borrower 
become insolvent or make an assignment for the benefit of any creditor or 
creditors or should a receiver or trustee be appointed for all or any 
significant part of any Borrower's assets, and shall continue to be effective 
or be reinstated, as the case may be, if at any time payment and performance 
of the Obligations, or any part thereof, is, pursuant to applicable law, 
rescinded or reduced in amount, or must otherwise be restored or returned by 
any obligee of the Obligations, whether as a "voidable preference," 
"fraudulent conveyance," or otherwise, all as though such payment or 
performance had not been made.  In the event that any payment, or any part 
thereof, is rescinded, reduced, restored or returned, the Obligations shall 
be reinstated and deemed reduced only by such amount paid and not so 
rescinded, reduced, restored or returned.

11.  CROSS-GUARANTY

          11.1 CROSS-GUARANTY.  Each Borrower hereby acknowledges and agrees
that such Borrower is jointly and severally liable for, and hereby absolutely
and unconditionally guarantees to each other Borrower and Lender the full and
prompt payment of, all Obligations owed or hereafter owing to Lender by each
other Borrowers.

          11.2 OBLIGATIONS ABSOLUTE.  The liability of each Borrower to Lender
hereunder shall not be affected or impaired by any of the following acts by
Lender:  (i) any acceptance of collateral security, guarantors, accommodation
parties or sureties for any or all Obligations; (ii) one or more extensions or
renewals of Obligations (whether or not for longer than the original period) or
any modification of the interest rates, fees, maturities or principal amount of,
or other contractual terms applicable to any Obligations; (iii) any waiver or
indulgence granted to a Borrower, any delay or lack of diligence in the
enforcement of Obligations, or any failure to institute proceedings, file a
claim, give any required notices or otherwise protect any Obligations; (iv) any
full or partial release of, compromise or settlement with, or agreement not to
sue a Borrower or any guarantor or other person liable in respect of any
Obligations; (v) any release, surrender, cancellation or other discharge of any
evidence of Obligations or the acceptance of any Instrument in renewal or
substitution therefore; (vi) any failure to obtain collateral security
(including rights of setoff) for Obligations, or to obtain or 

                                       61
<PAGE>

maintain the proper or sufficient creation and perfection thereof, or to 
establish the priority thereof, or to preserve, protect, insure, care for, 
exercise or enforce any collateral security; or any modification, alteration, 
substitution, exchange, surrender, cancellation, termination, release or 
other change, impairment, limitation, loss or discharge of any collateral 
security; (vii) any collection, sale, lease or disposition of, or any other 
foreclosure or enforcement of or realization on, any collateral security; 
(viii) any assignment, pledge or other transfer of any Obligations or any 
evidence thereof; or (ix) any manner, order or method of application of any 
payments or credits upon Obligations.  Each Borrower hereby waives any and 
all defenses and discharges available to a surety, guarantor, or 
accommodation co-obligor.

          11.3 WAIVER.  EACH BORROWER HEREBY WAIVES PRESENTMENT, DEMAND FOR 
PAYMENT, NOTICE OF DISHONOR OR NONPAYMENT, AND PROTEST OF ANY INSTRUMENT 
EVIDENCING OBLIGATIONS.

          11.4 RECOVERY. If any payment is applied by Lender to the 
Obligations and is thereafter set aside, recovered, rescinded or required to 
be returned for any reason (including, without limitation, the bankruptcy, 
insolvency or reorganization of a Borrower or any other obligor), the 
Obligations to which such payment was applied shall for the purposes of this 
SECTION 11 be deemed to have continued in existence, notwithstanding such 
payment and application and this cross guaranty shall be enforceable as to 
such Obligations as fully as if such payment and application had never been 
made.

          11.5 LIABILITY CUMULATIVE.  The liability of Borrowers under this 
SECTION 11 is in addition to and shall be cumulative with all liabilities of 
each Borrower to Lender under this Agreement and the other Loan Documents to 
which such Borrower is a party or in respect of any Obligations or obligation 
of the other Borrower, without any limitation as to amount, unless the 
Instrument or agreement evidencing or creating such other liability 
specifically provides to the contrary.

          FOR VALUE RECEIVED, the undersigned, AKORN, INC., a Louisiana 
corporation ("AKORN"), and TAYLOR PHARMACEUTICALS, INC., an Illinois

THE NORTHERN TRUST COMPANY (the "LENDER") on or before December 29, 1999, the 
principal amount of FIFTEEN MILLION DOLLARS ($15,000,000), or the amount 
outstanding as endorsed on the grid attached to this Note (or recorded in the 
Lender's books and records, if the Lender is the holder hereof).  Such 
endorsement or recording by the Lender shall, absent manifest error, be 
rebuttably presumptive evidence of the principal balance due on this Note.

          This Note evidences indebtedness incurred under that certain Credit 
Agreement, dated as of December 29, 1997 (as amended, restated, supplemented 
or otherwise modified, the "CREDIT AGREEMENT"), among Akorn, Taylor and the 
Lender, to which agreement reference is hereby made for a statement of its 
terms and provisions, including those under which this Note may be paid prior 
to its due date or have its due date accelerated, and pursuant to which the 
applicable interest rate herein set forth may be reduced.  All capitalized 
terms used but not otherwise defined herein shall have the meanings assigned 
to them in the Credit Agreement.

          Unless or until this Note shall sooner become due and payable, 
whether by acceleration or otherwise, the principal amount outstanding 
hereunder shall be paid in accordance with the terms and conditions of the 
Credit Agreement. The unpaid principal amount of this Note from time to time 
outstanding shall bear interest from the date of this Note at the rate per 
annum set forth in the Credit Agreement.  Accrued interest on this Note shall 
be payable in accordance with the terms of the Credit Agreement.  After 
maturity, whether by acceleration or otherwise, accrued interest shall be 
payable on demand.  Interest on this Note shall be computed for the actual 
number of days elapsed on the basis of a year consisting of 360 days.  
Payments of both principal and interest are to be made in immediately 
available funds in lawful money of the United States of America.

          Subject to the terms and conditions of the Credit Agreement, the 
undersigned agree to pay all reasonable expenses, including reasonable 
attorneys' fees and legal expenses, incurred by the holder of this Note in 
attempting to collect any amounts payable hereunder. The undersigned 
irrevocably waive presentment, protest, demand and notice of any kind in 
connection herewith.

now existing or hereafter arising, being individually called a "LIABILITY" 
and collectively the "LIABILITIES").

     4.   WARRANTIES OF BORROWERS.  Borrowers each jointly and severally
     warrants and represents that:

          (a)  Except to the extent specifically permitted in the Credit
     Agreement, no financing statement, mortgage, notice of judgment or any
     similar instrument (other than any which may have been filed on behalf of
     Secured Party) covering any of the Collateral is on file in any public
     office.

          (b)  Except to the extent specifically permitted in the Credit
     Agreement, Borrowers are and will be the lawful owner of all Collateral,
     free and clear of all liens, pledges, charges, mortgages, and claims other
     than the security interest hereunder or any other security interest created
     in favor of Secured Party, with full power and authority to execute this
     Agreement and perform Borrowers' obligations hereunder and to subject the
     Collateral to the security interest hereunder.

          (c)  Except for goods covered by negotiable warehouse receipts which
     have been delivered to Secured Party or as promptly disclosed to Secured
     Party from time to time in writing, all of the Collateral is located as set
     forth on SCHEDULE 4(f) attached hereto, and is not in transit, and except
     as promptly disclosed to Secured Party from time to time in writing, all
     Inventory shall be of good and merchantable quality, and free from any
     defects which would affect the market value of such Inventory, except for
     obsolete, damaged, or defective inventory, which is immaterial in amount,
     or against which there exists a reserve for inventory write down set forth
     on Borrowers' most recent balance sheet.

          (d)  (i) All accounts receivable of Borrowers are genuine, are in all
     respects what they purport to be, are not 

                                       3
<PAGE>

     evidenced by a judgment and represent undisputed, bona fide transactions
     completed or to be completed in accordance with the terms and conditions
     of any document related thereto; (ii) none of the Accounts have been sold
     or pledged to any other person or entity; and (iii) Borrowers have no 
     knowledge of any fact or circumstance which would impair the validity or
     collectability of the Accounts in excess of a bad debt reserve account or
     other contra-receivable account maintained by Borrowers.

          (e)  The only names by which any Borrower is known or under which any
     Borrower is conducting its business are set forth on SCHEDULE 4(e).

          (f)  Each Borrower's chief place of business and chief executive
     office and the office where it keeps its records concerning the Collateral
     is as set forth on SCHEDULE 4(f).

     5.   COVENANTS OF BORROWERS.  Borrowers each jointly and severally agree
that until payment in full of the Liabilities, they will:

          (a)  Provide and maintain insurance against loss and damage of the
     Collateral pursuant to the requirements of the Credit Agreement, and unless
     Secured Party otherwise agrees, shall cause all proceeds to be payable to
     Secured Party as its interests may appear and shall name Secured Party as
     an additional insured; the proceeds of such insurance shall be part of the
     Collateral subject to the security interest of Secured Party hereunder, and
     shall be applied as provided in the Credit Agreement.  At any time at the
     request of Secured Party, Borrowers shall deliver any such policies to
     Secured Party.

          (b)  Defend the Collateral against the claims and demands of all
     persons other than Secured Party and promptly pay all taxes, assessments,
     and charges upon the Collateral and not sign (or permit to be signed) any
     financing statements or other documents creating or perfecting a lien upon
     or security interest in any of the Collateral except in favor of Secured
     Party, or, except as otherwise specifically permitted in the Credit
     Agreement, otherwise create, suffer, or permit to exist any liens or
     security interests upon any Collateral other than in favor of Secured
     Party.

          (c)  At the request of Secured Party, execute and deliver to Secured
     Party at any time or from time to time one or more financing statements
     pursuant to the Code in form sufficient to perfect a lien on all of the
     Collateral, and will pay the cost of filing the same in  all public offices
     wherever filing is, or is deemed by Secured Party to be, reasonably
     necessary or desirable.  Borrowers hereby authorize Secured Party to

                                       4
<PAGE>

     prepare and to file, or cause to be filed, financing statements signed only
     by Secured Party covering the Collateral and, in jurisdictions where any
     Borrower's signature is required, Borrowers hereby authorize Secured Party
     to sign such Borrower's signature to such financing statements on such
     Borrower's behalf, and Borrowers agree to pay Secured Party all reasonable
     fees and expenses (including attorneys' fees) incurred in filing the
     financing statements, which fees and expenses shall become a part of the
     Liabilities.  A carbon, photographic or other reproduction of this Security
     Agreement or of any financing statements shall be sufficient as financing
     statement.

          (d)  Upon Secured Party's request, deliver any such certificates or
     other documents of title representing or issued with respect to any of the
     Collateral, with Secured Party's security interest and lien endorsed
     thereon, to Secured Party and record such certificates or documents with
     all appropriate regulatory agencies.

          (e)  Furnish to Secured Party, immediately upon the request of Secured
     Party, any evidence of ownership of the Collateral, including without
     limitation bills of sale, paid invoices, certificates of title, or
     applications for title.

          (f)  Keep at its principal place of business its records concerning
     the Collateral.  Borrowers shall not, unless Secured Party shall otherwise
     consent in writing, which consent shall not be unreasonably withheld,
     duplicate any such records at any other addresses, except for back-up
     copies created in the ordinary course of business, and Borrowers will
     furnish to Secured Party such information concerning Borrower, the
     Collateral, and the account debtors as Secured Party may from time to time
     reasonably request and Secured Party will keep such information
     confidential except from state or federal regulators of Secured Party and
     Secured Party's auditors or accountants, or others to whom Secured Party
     has a legal obligation to disclose such information; and Borrowers shall,
     subject to the terms of the Credit Agreement, permit Secured Party from
     time to time to inspect the Collateral and to inspect, audit, and make
     copies of, and extracts from, all records and all other papers in the
     possession of any Borrower pertaining to the Collateral and the accounts
     debtors.  After the occurrence and during the continuance of an Event of
     Default, Secured Party shall have the right at any time or times to make
     direct verification with the account debtors of any and all of the
     Accounts.

          (g)  Except for transactions in the ordinary course of Borrowers'
     business or otherwise expressly permitted by this Agreement and the other
     Loan Documents or by Secured Party in writing, Borrowers and their
     respective agents, servants or 

                                       5
<PAGE>

     employees will not sell or assign or otherwise transfer the Collateral,
     either in whole or in part, or any interest therein, nor, except for 
     transactions in the ordinary course of Borrowers' business, or otherwise
     expressly permitted by this Agreement and the other Loan Documents or by
     Secured Party in writing, will it remove or permit removal of any of the
     Collateral from the locations where it now is, without the written 
     consent of Secured Party.  Borrowers shall provide Secured Party at any
     time at Secured Party's request with a reasonably complete, specific 
     description of all the Collateral and the locations thereof and shall,
     subject to the terms of the Credit Agreement, at all reasonable times
     give Secured Party, its agents and representatives full access to the 
     Collateral.

          (h)  Keep and maintain the Equipment in good operating condition and
     repair (ordinary wear and tear excepted) and make all commercially and
     reasonably necessary replacements and renewals to the Equipment so that the
     value and operating efficiency thereof shall at all times be maintained and
     preserved.

          (i)  Make appropriate entries upon its financial statements and its
     books and records disclosing Secured Party's security interest in the
     Collateral.

          (j)  If at any time any of the Collateral shall be or become evidenced
     by any instrument, immediately notify Secured Party thereof, and, at the
     request of Secured Party, deliver such instrument to Secured Party,
     endorsed as requested by Secured Party.

          (k)  Immediately notify Secured Party of any material loss, damage,
     destruction, or depreciation in the value of the Collateral.

          (l)  Except as permitted by SECTION 5(g) or SECTION 6 hereof or in the
     Credit Agreement, not sell, transfer or otherwise dispose of any Collateral
     without Secured Party's prior written consent.

          (m)  Immediately notify Secured Party if any Borrower (i) is known by
     or conducting business under any name other than the name described in
     SECTION 4(e) of this Agreement, (ii) is conducting any of its business or
     operations at or out of offices or locations other than as described in
     SCHEDULE 4(f) of this Agreement, or (iii) changes the location of its
     principal office from the location described in SCHEDULE 4(f) of this
     Agreement.

          (n)  Use its best efforts to obtain (i) a landlord's agreement in form
     and substance acceptable to Secured Party 

                                       6
<PAGE>

     from the lessor of each leased property currently being used by any 
     Borrower where Collateral is  located, (ii) a bailee letter in form
     and substance acceptable to Secured Party and with respect to any
     warehouse where Collateral is located and (iii) a mortgagee's agreement
     in form and substance satisfactory to Secured Party from the mortgagee
     (if other than Secured Party) of each property owned by any Borrower 
     where Collateral is located.  No real property or warehouse space shall
     be leased or acquired by any Borrower after the Closing Date,
     unless and until a landlord or mortgagee agreement or bailee letter, as
     appropriate, shall first have been obtained with respect to such location.

     6.   USE OF THE COLLATERAL.  Until notice to the contrary is given by
Secured Party after the occurrence and during the continuance of an Event of
Default, Borrowers may conduct their business in the ordinary course of business
substantially in the same manner as now conducted and may use, consume, or sell
the Collateral for such purposes, but a sale in the ordinary course of business
shall not include any transfer or sale in satisfaction, partial or complete, of
a debt owed by any Borrower.

     7.   COLLECTIONS.

          (a)  At any time and from time to time, after the occurrence and
     during the continuance of an Event of Default, Secured Party may, upon
     notice to Akorn and at Borrowers' reasonable expense, or, upon request of
     Secured Party, Borrowers shall (i) notify any account debtors of the
     existence of this Agreement, and (ii) direct such account debtors to pay
     directly to Secured Party the amounts due or to become due from such
     account debtors.  Each account debtor so notified and directed may accept
     the receipt of Secured Party for any such payment as a full release of any
     amounts so paid; and

          (b)  If an Event of Default shall have occurred and be continuing,
     Secured Party may enforce collection of any or all of the Collateral by
     suit or otherwise, and surrender, release or exchange all or any part
     thereof, or compromise or extend or renew for any period (whether or not
     longer than the original period) any indebtedness thereunder; and

          (c)  Secured Party shall upon direction of Borrowers or may upon the
     happening and during the continuance of an Event of Default, apply all
     payments received from account debtors to the Liabilities when due (whether
     by acceleration or otherwise) and may credit any balance after such payment
     to the account of Borrowers.

                                       7
<PAGE>

     8.   EVENTS OF DEFAULT. The occurrence of an Event of Default as defined in
the Credit Agreement or the Loan Documents, shall constitute an Event of Default
hereunder.

     9.   REMEDIES ON DEFAULT. If an Event of Default shall have occurred and be
continuing, Secured Party, in addition to any other rights set forth in the
Credit Agreement or other Loan Documents or as set forth herein, shall have all
the rights and remedies of a secured party under the Code, as to any Collateral
located in Illinois, and under the Uniform Commercial Code of any other
jurisdiction as to any Collateral therein located (whether or not the Code or
such other Uniform Commercial Code applies to the affected Collateral) and shall
further have, in addition to all other rights and remedies provided herein or by
law, the following rights and powers:

          (a)  Secured Party shall have the right to take possession of the
     Collateral and, for that purpose, may enter, with the aid and assistance of
     any person or persons, any premises where the Collateral, or any part
     thereof, is, or may be, placed and remove the same.

          (b)  Secured Party may require Borrowers to assemble the Collateral
     and to make it available to Secured Party at a place designated by Secured
     Party which is reasonably convenient to Secured Party and Borrowers.

          (c)  Secured Party shall have the right from time to time to sell,
     resell and deliver all or any part of the Collateral, at public or private
     sale or otherwise, at the option of Secured Party, for cash or on credit or
     for future delivery, in such parcel or parcels and at such time or times
     and at such place or places, and upon such terms and conditions as Secured
     Party may deem proper, all without (except as shall be required by
     applicable statute and which cannot be waived) advertisement or demand upon
     or notice to Borrowers or right of redemption of Borrowers, which are
     hereby expressly waived to the fullest extent permitted by law and any
     purchaser of Collateral at any such sale (including Secured Party) shall
     acquire the same absolutely free from any right or claim of any kind,
     including without limitation any equity of redemption which, together with
     all rights of redemption, stay or appraisal which Borrowers may have under
     any rule or statute Borrower hereby specifically and unconditionally waives
     to the fullest extent permitted by law; Secured Party shall give to Akorn
     at least fifteen (15) days' prior written notice, in the manner specified
     in SECTION 15(b) hereof of the time and place of any public sale or the
     time after which any private sale or any other intended disposition is to
     be made, and any such notice shall be deemed to satisfy any requirement of
     reasonable notice.  Borrowers shall at all times remain liable for any
     deficiency on the Liabilities.

                                       8
<PAGE>

          (d)  Upon each such sale, Secured Party may, unless prohibited by
     applicable statute which cannot be waived, purchase all or any part of the
     Collateral being sold, free from and discharged of all trusts, claims,
     right of redemption and equities of Borrowers, which are hereby waived and

          (e)  Secured Party may, in its discretion, apply all proceeds received
     by Secured Party in respect of any sale of, collection from or other

     amounts payable to Secured Party pursuant to SECTION 11 hereof) in whole or

          (f)  Secured Party shall have the absolute right, in its sole
     discretion, to dishonor checks drawn on deposit accounts maintained by

     collateral to secure payment of the Liabilities.  Notwithstanding the
     foregoing, nothing contained herein shall interfere with the right of
     Secured Party under law to set off the balances of any such deposit account
     against the Liabilities.

     10.  RIGHTS OF SECURED PARTY.  Secured Party may, from time to time, at its
option (but shall have no duty to):

the custody, preservation, use or operation of, or the sale of, collection 
from or other realization upon, any of the Collateral, (ii) the exercise by 
Secured Party of any of its rights or powers hereunder, or (iii) any failure 
by Borrowers to perform or observe the provisions hereof.  All such expenses

or reimbursement of itself for such expenses.

     12.  RESPONSIBILITY FOR COLLATERAL.  Borrowers assume all liabilities

     13.  POWER OF ATTORNEY.  Each Borrower hereby irrevocably appoints

at any time in Secured Party's absolute discretion to do any and all things 
required to be done to carry out the terms or to accomplish the purposes of 
this Security Agreement as fully and effectually as such Borrower could do

otherwise as provided in this Security Agreement and neither Secured Party 
nor any of its officers, employees or agents shall be liable for any acts or 
omissions or for any error of judgment or mistake of fact or law except for 
gross negligence or willful misconduct in its or their capacity as such 
attorney-in-fact.  This power of attorney is coupled with an interest and 
shall be irrevocable until all of the Liabilities are paid in full and this 
Security Agreement is terminated. The powers conferred upon Secured Party 
hereunder are solely to protect its interests and shall not impose any duty 
upon it to exercise any of such powers.

     14.  CONTINUING SECURITY INTEREST.  This Security Agreement shall create a
continuing and, except as otherwise permitted hereunder and under the Credit
Agreement, first security interest in the Collateral and shall remain in full
force and effect until the payment in full in cash of the Liabilities and

     15.  GENERAL.

          (a)  NONWAIVER; CUMULATIVE REMEDIES.  No delay or omission on the part
     of Secured Party in the exercise of any right or remedy shall operate as a
     waiver thereof, and no single or partial exercise by Secured Party of any
     right or remedy shall preclude other or further exercise thereof or the
     exercise of any other right or remedy.  All options, powers and rights
     granted to Secured Party hereunder or under the Credit Agreement, the
     Notes, or any other agreements, documents or instruments or under law shall
     be cumulative and shall be in addition to any other options, powers and
     rights of Secured Party under other applicable law or otherwise.

          (b)  NOTICES.  Except as otherwise permitted herein, any notices or
     consents required or permitted by this Agreement shall be in writing and
     delivered as provided in SECTION 10.11 of the Credit Agreement.

          (c)  RETURN OR RELEASE OF COLLATERAL.  At such time as Borrowers shall
     pay all of the Liabilities and the Credit Agreement shall be terminated,
     Secured Party shall return or release its interest in all Collateral upon
     Akorn's request.

          (d)  SUCCESSORS AND ASSIGNS.  This Agreement shall, upon execution and
     delivery by Borrowers, become effective and shall be binding upon and inure
     to the benefit of Borrowers and Secured Party and their respective
     successors and assigns, except that no Borrower may transfer or assign any
     of its rights or interest hereunder without the consent of Secured Party. 
     If at any time or times, by sale, assignment, negotiation, pledge or
     otherwise, Secured Party transfers any Liability or Liabilities, which,
     subject to the terms of the 

                                       11

     it Secured Party's rights, powers and remedies under this Security 
     Agreement with respect to the Liability transferred, and the transferee
     shall become vested with such rights and remedies whether or not they 
     are specifically referred to in the transfer, unless, and then only to
     the extent, that the terms of such transfer otherwise provide.  If and
     to the extent Secured Party retains any other Liability and Liabilities,
     Secured Party shall continue to have the rights, powers and remedies 
     herein set forth with respect thereto.

          (e)  CAPTIONS.  Captions in this Agreement are for convenience of

     constitute one and the same instrument.

     the parties hereunder shall be governed by, and construed and interpreted
     in accordance with, the internal laws of the State of Illinois (without
     regard to conflict of law provisions thereof).

     Secured Party as provided in and pursuant to SECTION 10.4 of the Credit
     Agreement for all costs, expenses and fees (including reasonable legal fees

$25,000,000                                                   Chicago, Illinois

     FOR VALUE RECEIVED, the undersigned, AKORN, INC., a Louisiana corporation
("AKORN"), and TAYLOR PHARMACEUTICALS, INC., an Illinois corporation ("TAYLOR"),
jointly and severally, promise to pay to the order of THE NORTHERN TRUST COMPANY
(the "Lender") on or before December 29, 1999, the principal amount of
TWENTY-FIVE MILLION DOLLARS ($25,000,000), or the amount outstanding as endorsed
on the grid attached to this Note (or recorded in the Lender's books and
records, if the Lender is the holder hereof).  Such endorsement or recording by
the Lender shall, absent manifest error, be rebuttably presumptive evidence of
the principal balance due on this Note.

     This Note evidences indebtedness incurred under that certain Credit
Agreement, dated as of December 29, 1997, as amended by a First Amendment
thereto dated as of March 27, 1998, and a Second Amendment thereto dated as of
June 30, 1998 (as the same may be subsequently further amended, restated,
supplemented or otherwise modified, the "CREDIT AGREEMENT"), among Akorn, Taylor
and the Lender, to which agreement reference is hereby made for a statement of
its terms and provisions, including those under which this Note may be paid
prior to its due date or have its due date accelerated, and pursuant to which
the applicable interest rate herein set forth may be reduced.  All capitalized
terms used but not otherwise defined herein shall have the meanings assigned to
them in the Credit Agreement.  This Note constitutes a renewal and restatement
of, and a replacement and substitute for, the Note dated as of December 29,
1997, of the undersigned payable to the order of the Lender in the principal
amount of $15,000,000  (the "Original Note").  The indebtedness under the
Original Note is continuing indebtedness hereunder, and nothing herein shall be
deemed to release or otherwise adversely affect any lien, mortgage or security
interest securing such indebtedness or any rights of the Lender against any
guarantor, surety or other party primarily or secondarily liable for such
indebtedness.

     Unless or until this Note shall sooner become due and payable, whether by
acceleration or otherwise, the principal amount outstanding hereunder shall be
paid in accordance with the terms and conditions of the Credit Agreement.  The
unpaid principal amount of this Note from time to time outstanding shall bear
interest from the date of this Note at the rate per annum set forth in the
Credit Agreement.  Accrued interest on this Note shall be payable in accordance
with the terms of the Credit Agreement.  After maturity, whether by acceleration
or otherwise, accrued interest shall be payable on demand.  Interest on this
Note shall be computed for the actual number of days elapsed on the basis of a
year consisting of 360 days.  Payments of both principal and interest are to be
made in immediately available funds in lawful money of the United States of
America.

     Subject to the terms and conditions of the Credit Agreement, the
undersigned agree to pay 

<PAGE>

all reasonable expenses, including reasonable attorneys' fees and legal 
expenses, incurred by the holder of this Note in attempting to collect any 
amounts payable hereunder.  The undersigned irrevocably waive presentment, 
protest, demand and notice of any kind in connection herewith.

     This Note is made under and governed by the internal laws of the State of
Illinois (without regard to conflict of laws provisions thereof), and shall be
deemed to have been executed in the State of Illinois.
