                               PROSPECTUS SUMMARY
 
    The following summary is qualified in its entirety by the more detailed
information and financial statements, including the notes thereto, appearing
elsewhere in this Prospectus. Unless otherwise indicated, references to the
Company include Halsey Drug Co., Inc. and its subsidiaries.
 
    Unless otherwise indicated, the information included in this Prospectus does
not give effect to the exercise of options granted or to be granted by the
Company, or to the exercise or conversion of the Convertible Securities.
 
                                  THE COMPANY
 
    Halsey Drug Co., Inc. ("Halsey"), a New York corporation established in
1935, and its subsidiaries (collectively, the "Company"), are engaged in the
manufacture, sale and distribution of generic drugs. A generic drug is the
chemical and therapeutic equivalent of a brand-name drug for which patent
protection has expired. A generic drug may only be manufactured and sold if
patents (and any additional government-granted exclusivity periods) relating to
the brand-name equivalent of the generic drug have expired. A generic drug is
usually marketed under its generic chemical name or under a brand name developed
by the generic manufacturer. The Company sells its generic drug products under
its Halsey label and under private-label arrangements with drugstore chains and
drug wholesalers. While subject to the same governmental standards for safety
and efficacy as its brand-name equivalent, a generic drug is usually sold at a
price substantially below that of its brand-name equivalent.
 
    During the past several years, the Company's business has been adversely
affected by the discovery of various manufacturing and record keeping problems
identified with certain products manufactured at its Brooklyn, New York plant.
These problems caused the Company to halt production and sale of a number of
products and to establish a $2,000,000 reserve as of December 31, 1992, and a
reserve of $3,875,000 in 1993 to cover estimated costs associated with inventory
write-offs, recalls of the affected products and estimated additional legal
expenses.
 
    On June 21, 1993, the Company entered into a plea agreement (the "Plea
Agreement") with the United States Department of Justice (the "DOJ") to resolve
the DOJ's investigation into the manufacturing and recordkeeping practices at
the Company's Brooklyn plant. Under the terms of the plea agreement, the Company
agreed to plead guilty to five counts of adulteration of a single drug product
shipped in interstate commerce and related recordkeeping violations. The plea
agreement also requires the Company to pay a fine of $2,500,000 over five years
in quarterly installments of $125,000 commencing in September 1993. The Company
has not remained current on such payments. See "Legal Proceedings--Government
Consent Decrees."
 
    On June 29, 1993, the Company entered into a consent decree with the U.S.
Attorney for the Eastern District of New York on behalf of the Food & Drug
Administration (the "FDA") that resulted from the FDA's investigation into the
Brooklyn plant's compliance with the FDA's Current Good Manufacturing Practice
("CGMP") regulations. Under the terms of the consent decree, the Company was
enjoined from shipping any solid dosage drug products (i.e., excluding liquid
drug formulations) manufactured at the Brooklyn plant until the Company
established, to the satisfaction of the FDA, that the methods used in, and the
facilities and controls to be used for, manufacturing, processing, packing,
labeling and holding any drug, are established, operated, and administered in
conformity with the Federal Food, Drug, and Cosmetic Act and all CGMP
regulations. The Company, however, was permitted under the terms of the consent
decree to manufacture and ship from the Brooklyn plant certain identified solid
dosage drug products ("the "Brooklyn Solid Dosage Products") provided that it
meet certain conditions set forth in the consent decree. See "Legal
Proceedings--Government Consent Decrees."

    The Company conducts research and development activities at its Brooklyn and
Indiana facilities. The Company's research and development activities consist
primarily of new generic drug product development efforts and manufacturing
process improvements, as well as the development for sale of new chemical
products. There can be no assurance that the FDA will grant the requisite
approvals for any such product introductions. See "Risk Factors."

                                  RISK FACTORS
 
    Prospective purchasers of the securities offered hereby should carefully
consider the following factors, as well as the information contained elsewhere
in this Prospectus.
 
NEED FOR ADDITIONAL FINANCING AND CAPITAL RESOURCES
 
    The Company currently has insufficient resources to satisfy all of its
contemplated cash requirements for the 12 month period following the date of
this Prospectus. For example, the Company's Credit Agreement with its banks
matured on March 31, 1996, at which time the Company was required to repay all
outstanding principal plus any accrued interest, or approximately $3,395,000 of
principal and $31,000 of interest. The Company has not yet repaid such amount
and interest continues to accrue. In addition, pursuant to the Plea Agreement
with the DOJ, the Company is required to satisfy a $2,500,000 fine by making
quarterly payments of $125,000. As of the date of this Prospectus, $2,160,000 of
the fine remains outstanding. Two installments of $125,000 each and additional
amounts totaling $90,000 have been paid to date. Pursuant to the terms of the
Plea Agreement the entire fine is currently due and payable. Accordingly, the
entire amount of the settlement has been classified as current. As of the date
of this Prospectus no action has been initiated to require the Company to pay
the entire outstanding amount of the fine. The banks whose debt is secured by
assets of the Company could foreclose on substantially all Company assets.
 
    The Company will require additional funding to meet its obligations under
the Credit Agreement, the Plea Agreement and its other operating expenses. The
Company has not entered into any arrangements to obtain such financing, and
there can be no assurance that the Company will be able to obtain such financing
on commercially acceptable terms. The unavailability of additional funding could
prevent or delay the continued development and marketing of the Company's
products and could require the Company to curtail its operations. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" and "Business."
 
INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS' REPORT WITH DISCLOSURE OF GOING
CONCERN ISSUE
 
    The report of the Company's independent certified public accountants, which
is included herein, contains an explanatory paragraph as to the Company's
ability to continue as a going concern. Among the factors cited by the
accountants as raising substantial doubt as to the Company's ability to continue
as a going concern are: the loss incurred by the Company of approximately
$2,203,000 during the year ended December 31, 1995; the Company's working
capital deficiency of approximately $7,393,000 at that date; the expiration of
the Credit Agreement on March 31, 1996; and the uncertainties concerning the FDA
consent decree and the ongoing inquiry by the Commission. See Note A of Notes to
Consolidated Financial Statements. See also "Management's Discussion and
Analysis of Financial Condition and Results of Operations" for management's
discussion of the Company's financial condition at December 31, 1995.
 
DEPENDENCY ON PRODUCT DEVELOPMENT
 
    The Company historically has manufactured and sold a broad range of
prescription and over-the-counter drug products. The Company's future success
will be largely dependent on its ability to develop, manufacture and market
commercially viable generic pharmaceutical products.
 
    In October 1991, the FDA suspended review of all of the Halsey's (but not
Houba's) applications for new drug approvals. It is unlikely that Halsey will
receive any new approvals to market any generic drugs from the FDA in 1996. See
"Legal Proceedings."
 
    Development activities for each new generic drug product begin several years
in advance of the patent expiration date of the brand-name drug equivalent. This
is because the profitability of a new generic drug usually depends on the
ability of the Company to obtain FDA approval to market that drug product upon
or immediately after the patent expiration date of the equivalent brand-name
drug so that
 
                                       6
<PAGE>
the Company will be among the first to market the new generic drug product. As
other off-patent drug manufacturers receive FDA approvals on competing products,
prices and revenues typically decline. Accordingly, the Company's ability to
attain profitable operations depends on the Company's ability to develop and
introduce new products, the resumption of FDA review of the Company's
application for new drug approvals at its Brooklyn plant, the timing of FDA
approval of such products and the number and timing of FDA approvals for
competing products.
 
GOVERNMENTAL REGULATION
 
    The development, manufacture and sale of pharmaceutical products are subject
to strict regulation and approval by the federal government, principally the
FDA, and, to a lesser extent, by state and local governments. The process of
obtaining regulatory approval is rigorous, time consuming and costly. There can
be no assurance that the Company will obtain necessary approvals on a timely
basis, if at all. Delays in receiving regulatory approvals would adversely
affect the Company's ability to market products commercially. Product approvals
by the FDA may be withdrawn if compliance with regulatory standards is not
maintained or if problems relating to the products are experienced after the
initial approval.
 
HEALTHCARE REFORM
 
    Several legislative proposals to address the rising costs of healthcare have
been introduced in Congress and several state legislatures. Many of such
proposals include various insurance market reforms, the requirement that
businesses provide health insurance coverage for all their employees,
significant reductions in the growth of future Medicare and Medicaid
expenditures, and stringent government cost controls that would directly control
insurance premiums and indirectly affect the fees of hospitals, physicians and
other healthcare providers. Such proposals could adversely affect the Company's
business by, among other things, reducing the demand, and the prices paid, for
pharmaceutical products such as those produced and marketed by the Company.
Additionally, other developments, such as (i) the adoption of a nationalized
health insurance system or a single payor system, (ii) changes in needs-based
medical assistance programs, or (iii) greater prevalence of capitated
reimbursement of healthcare providers, could adversely affect the demand for the
Company's products.
 
COMPETITION
 
    The Company competes in varying degrees with numerous companies in the
healthcare industry, including other manufacturers of generic drugs (among which
are several major pharmaceutical companies) and manufacturers of brand-name
drugs. Many of the Company's competitors have substantially greater financial
and other resources and are able to expend more money and effort than the
Company in areas such as marketing and product development. Although a company
with greater resources will not necessarily receive FDA approval for a
particular generic drug before its smaller competitors, relatively large
research and development expenditures enable a company to support many FDA
applications simultaneously, thereby improving the likelihood of being among the
first to obtain approval of at least some generic drugs.
 
    One of the principal competitive factors in the generic pharmaceutical
market is the ability to introduce generic versions of brand-name drugs promptly
after a patent expires. The Company believes that it will be at a competitive
disadvantage until the FDA resumes review of Abbreviated New Drug Applications
("ANDAs") submitted by the Company's Brooklyn plant. See "Legal Proceedings-
Government Consent Decrees." Other competitive factors in the generic
pharmaceutical market are price, quality and customer service (including
maintenance of sufficient inventories for timely deliveries).
 
RAW MATERIALS
 
    The raw materials essential to the Company's business are bulk
pharmaceutical chemicals purchased from numerous sources. Raw materials are
generally available from several sources. During
 
                                       7
<PAGE>
1995, the Company purchased a substantial amount of its raw materials from
Mallinckrodt Chemical, Inc. (Mallinckrodt Chemical, Inc. and/or its affiliates
are hereafter referred to as "Mallinckrodt"). If the Company became unable to
continue to purchase raw materials from this supplier, there can be no assurance
that the Company will not face difficulties in obtaining raw materials on
commercially acceptable terms from alternate suppliers, which could have a
material adverse effect on the Company. In addition, the federal drug
application process requires specification of raw materials suppliers. If raw
materials from a supplier specified in a drug application were to become
unavailable on commercially acceptable credit terms, FDA supplemental approval
of any new supplier would be required. In 1994, one of the Company's suppliers
filed a Chapter 11 petition under the United States Bankruptcy Code. The
supplier continues to supply the Company but there can be no assurance it will
continue to do so. See "Business--Products and Product
Developments--Acquisitions." In view of the FDA consent decree and the
suspension of review of the Company's ANDAs by the FDA, the Company would be
unable to obtain FDA supplemental approval at the Brooklyn plant for a new
supplier except in very limited circumstances.
 
    The United States Drug Enforcement Administration (the "DEA") limits the
quantity of the Company's inventories of certain raw materials used in the
production of controlled substances based on historical sales data. These
limitations could increase the likelihood of raw material shortages and of
manufacturing delays in the event the Company was required to find new suppliers
of these raw materials.
 
HISTORICAL LOSSES AND ACCUMULATED DEFICIT
 
    The Company has had net losses in each of the last three years of its
operation. For the years ended December 31, 1995, 1994 and 1993, the Company had
net losses of $2,203,000, $5,767,457 and $10,902,760, respectively. At December
31, 1995, the Company had an accumulated retained earnings deficit of
$13,089,000.
 
USE OF PROCEEDS
 
    Although the Company will receive all of the proceeds from the exercise of
the Redeemable Warrants, the Bank Warrants and the Options, there can be no
assurance that any of such securities which remain outstanding will be exercised
by the holders thereof. The Company currently intends to utilize a significant
portion of any such proceeds for working capital and general corporate purposes.
Accordingly, the Company will have broad discretion as to the application of a
substantial portion of the net proceeds, if any, derived from the exercise of
outstanding Redeemable Warrants, Bank Warrants and Options. None of the proceeds
from the sale of shares of Common Stock offered hereby by the Selling
Securityholders (including the Underlying Shares) will go to the Company. See
"Use of Proceeds."
 
NO DIVIDENDS
 
    The Company has not declared and paid cash dividends on its Common Stock in
the past, and the Company does not anticipate paying any cash dividends in the
foreseeable future. Certain of the Company's debt instruments prohibit the
payment of cash dividends. Earnings, if any, will be retained to finance the
Company's operations and to expand its business. See "Dividend Policy."
 
CONTINUED EXCHANGE LISTING
 
    In April 1995, the Exchange halted trading in the Common Stock because the
Company had not fully satisfied the Exchange's financial guidelines for
continued listing of the Common Stock. Although trading resumed on May 16, 1995,
there is no assurance that such listing will continue. If the Common Stock
should become delisted from the Exchange, trading, if any, in the Common Stock
would then continue to be conducted in the over-the-counter market on the Nasdaq
Small-Cap market (if the Common Stock qualifies for inclusion therein), on the
OTC Bulletin Board, an NASD-sponsored inter-dealer quotation system, or in what
are commonly referred to as "pink sheets." As a result, an investor
 
                                       8
<PAGE>
may find it more difficult to dispose of, or to obtain accurate quotations as to
the market value of, the Common Stock. In addition, if the Common Stock ceases
to be quoted on the Exchange or is not qualified for inclusion on the Nasdaq
Small-Cap market and the Company fails to meet certain other criteria, the
Common Stock would be subject to a Commission rule that imposes additional sales
practice requirements on broker-dealers who sell such securities to persons
other than established customers and accredited investors. For transactions
covered by this rule, the broker-dealer must make a special suitability
determination for the purchaser and have received the purchaser's written
consent to the transaction prior to sale. Consequently, if the Company's
securities were no longer listed on the Exchange or were not quoted on Nasdaq,
the rule may affect the ability of broker-dealers to sell the Company's
securities and the ability of purchasers in this offering to sell the Underlying
Shares in the secondary market.
 
CURRENT PROSPECTUS AND STATE BLUE SKY REGISTRATION REQUIRED TO ISSUE UNDERLYING
SHARES
 
    The Company will be able to issue Underlying Shares upon conversion or
exercise of the Convertible Securities only if a current prospectus relating to
such shares is then in effect and only if the shares are qualified for sale
under the securities laws of the applicable state or states or an exemption from
any such qualification is available. Although the Company has undertaken to
maintain such a current prospectus and intends to seek to qualify the Underlying
Shares for sale in applicable jurisdictions, there is no assurance that it will
be able to do so. See "Description of Securities."
 
DEPENDENCE ON CERTAIN CUSTOMERS AND PRODUCTS
 
    The Company sells its products to a large number of customers who are
primarily drug store chains and wholesalers. These customers are not
concentrated in any particular region. The Company performs ongoing credit
evaluations of its customers and generally does not require collateral. During
1995, the Company had net sales to two customers in excess of 10% of total
sales. Such customers accounted for 25% and 11% of total sales, respectively.
During 1994, the Company had net sales to three customers in excess of 10% of
total sales, each aggregating 12% of total sales. During 1993, the Company had
net sales to two customers in excess of 10% of total sales, each aggregating 12%
of total sales. Balances due from these customers were approximately 25%, 7% and
14% of total accounts receivable at December 31, 1995, 1994 and 1993,
respectively. The Company believes that the loss of any of these customers could
have a material adverse effect on the Company.
 
    In March 1995, the Company sold its Oxycodone with Acetaminophen Tablet
business ("Tablets ANDA") to Mallinckrodt. In connection with the sale of the
Tablets ANDA the Company has granted to Mallinckrodt an option to purchase the
Company's ANDA for Oxycodone with Acetaminophen Capsules ("Capsule ANDA")
business. See "Business--Products and Product Development--Dispositions" for a
description of the Company's transaction with Mallinckrodt.
 
COMMISSION PROCEEDINGS
 
    In November 1993, the staff (the "Staff") of the Commission requested that
the Company provide to the Commission, on a voluntary basis, information and
documents regarding the ingredients and filings relating to several drugs
manufactured and sold by the Company. The Staff advised the Company that the
inquiry related to public information disseminated by the Company and trading in
the Company's securities during the period August 1987 through July 1993. The
Company is cooperating with the Staff and has made available various documents.
In addition, officers and directors of the Company have testified before the
Staff. On October 24, 1995, the Staff informed the Company that it would
recommend that the Commission authorize the institution of an administrative
proceeding pursuant to Section 21C of the Exchange Act against the Company. The
proposed action would allege that the Company's December 31, 1990 and December
31, 1991 Annual Reports on Form 10-K and March 31, 1991, June 30, 1991,
September 30, 1991, March 31, 1992, June 30, 1992, and September 30, 1992
quarterly reports on Form 10-Q were materially false and misleading. The Staff
proposal conforms in large part to the settlement proposal submitted by the
Company. The Company is unable to
 
                                       9
<PAGE>
predict the likelihood of the Commission adopting the Staff proposal. An adverse
determination in this regard could have a material adverse effect on the
Company's financial condition. See "Legal Proceedings--Other Governmental
Proceedings."
 
MARKET OVERHANG FROM OPTIONS, WARRANTS AND CONVERTIBLE NOTES
 
    Immediately after the Offering, the Company will have outstanding a number
of options, warrants and convertible promissory notes, including the Convertible
Securities described herein. To the extent that such stock options, warrants or
convertible promissory notes are exercised or converted, as the case may be, the
equity interests of the Company's current stockholders will be diluted.
Moreover, the terms upon which the Company may be able to obtain additional
equity capital may be adversely affected since the holders of the outstanding
options, warrants and convertible promissory notes can be expected to exercise
or convert them, as the case may be, to the extent they are able to, at a time
when the Company would, in all likelihood, be able to obtain any needed capital
on terms more favorable to the Company than those provided in the options,
warrants and convertible promissory notes. Further, the sale of Common Stock or
other securities held by or issuable to the holders of such options, warrants
and convertible promissory notes, including the Underlying Shares offered
hereby, or merely the potential of such sales, could have an adverse effect on
the market price of the Company's Common Stock.
 
LIMITATION ON FUTURE INDEBTEDNESS
 
    Pursuant to the terms of the Debentures, the Company is limited as to the
type of future indebtedness it may incur. Other than trade indebtedness and
purchase money indebtedness, the Company may only borrow from banks and other
financial institutions. To the extent such borrowing is senior to the
Debentures, the Company is limited in the amount of such indebtedness it may
incur. See "The Private Offerings--General."
 
RIGHT OF FIRST REFUSAL
 
    In November 1995, the Company granted the purchasers of the November
Debentures a right of first refusal with respect to future equity sales by the
Company. As a result, the Company may in the future have difficuly attracting
new investors because investors' offers to purchase equity securities will be
subject to such right of first refusal. See "The Private Offerings--November
Private Offering."
 
POSSIBLE VOLATILITY OF STOCK PRICE
 
    The market for the Company's Common Stock could be subject to wide
fluctuations in response to such factors as, among others, variations in the
Company's anticipated or actual results of operations and market conditions
(which may be unrelated to the Company's operation and/or performance). See
"Stock Price and Dividend Policy."
 
CONTROL OF THE COMPANY
 
    Several persons beneficially own over 5% of the Common Stock of the Company.
One person controls 28% of the Common Stock. Some of such persons acting alone
or together could control or strongly affect the votes of shareholders for
directors of the Company. In addition, holders of the November Debentures are
entitled to nominate two persons to the Board of Directors of the Company. See
"Principal Shareholders" and "The Private Offering."

<PAGE>
                             THE PRIVATE OFFERINGS
 
THE JULY PRIVATE OFFERING
 
    The Company consummated a private offering (the "July Private Offering") of
408 units of securities on July 18, 1995 for an aggregate purchase price of
$4,080,000. Each unit consisted of (i) a July Debenture in the principal amount
of $10,000 issued at par and (ii) 750 July Redeemable Warrants.
 
    The July Debentures will become due and payable as to principal five years
from the date of issuance. Interest, at the rate of 10% per annum, is payable on
a quarterly basis. The July Debentures are convertible at any time after
issuance into Underlying Shares at a conversion price (the "Conversion Price")
of $2.00 per share, subject to adjustment.
 
    Each July Redeemable Warrant entitles the holder to purchase one Underlying
Share for $2.00 during the five year period commencing on the date of issuance.
The July Redeemable Warrants are redeemable by the Company at a price of $.01
per Warrant at any time commencing one year after issuance, upon not less than
30 days prior written notice, if the last sale price of the Common Stock on the
Exchange following such one year anniversary equals or exceeds $2.00 per share,
subject to adjustment, for the 20 consecutive trading days ending on the third
day prior to the notice of redemption to holders.
 
THE NOVEMBER PRIVATE OFFERING
 
    The Company consummated a private offering (the "November Private Offering"
and, collectively with the July Private Offering, the "Private Offerings") of
366 units on November 29, 1995 for an aggregate purchase price of $3,660,000.
Each unit consisted of (i) a November Debenture in the principal amount of
$10,000 issued at par and (ii) 600 November Redeemable Warrants.
 
    The November Debentures will become due and payable as to principal five
years from the date of issuance. Interest, at the rate of 10% per annum, is
payable on a quarterly basis. The November Debentures are convertible at any
time after issuance into Underlying Shares at a Conversion Price of $2.50 per
share, subject to adjustment.
 
    Each November Redeemable Warrant entitles the holder to purchase one
Underlying Share for $2.50 during the five year period commencing on the date of
issuance. The November Redeemable Warrants are redeemable by the Company at a
price of $.01 per Warrant at any time commencing one year after issuance, upon
not less than 30 days prior written notice, if the last sale price of the Common
Stock on the Exchange following such one year anniversary equals or exceeds
$2.50 per share, subject to adjustment, for the 20 consecutive trading days
ending on the third day prior to the notice of redemption to holders.
 
    Holders of the November Debentures and any shares into which such Debentures
are converted have a right of first refusal while the November Debentures
remain outstanding to participate in any offering of securities by the Company
to the extent the gross proceeds from such offering, or series of offerings in a
twelve month period, exceed $200,000.
 
GENERAL
 
    Pursuant to the terms of Debentures, other than trade indebtedness and
purchase money indebtedness, the Company may only borrow from banks and other
financial institutions. Pursuant to the terms of the July Debentures only up to
$5,522,000 over a base amount of bank indebtedness of $3,278,000 in debt which
is senior to the July Debentures may be incurred from banks or other financial
institutions. Pursuant to the terms of the November Debentures up to $6,722,000
over a base amount of bank indebtedness of $3,278,000 in debt which is senior to
the July Debentures may be incurred from banks
 
                                       11
<PAGE>
or other financial institutions. This amount includes an existing $1,200,000
secured note issued to Mallinckrodt.
 
    The holders of the Debentures and the Redeemable Warrants and the shares
underlying such instruments are entitled to demand that the Company register the
shares underlying their securities and also may participate in a registration by
the Company of its securities.
 
    Subscriptions for units were solicited by management of the Company on a
'best efforts' basis. HKS & Co., Inc. ("HKS") assisted the Company in the
Private Offerings. For its services, the Company paid HKS consideration valued
at $392,000, and reimbursed HKS in the amount of approximately $40,000 for its
expenses. HKS is a Selling Securityholder in connection with the Offering
described herein. See "Selling Securityholders." HKS may receive a fee in
connection with the exercise of Redeemable Warrants.
 
    The net proceeds of the Private Offerings were approximately $7,013,000. The
Company utilized $1,100,000 of such proceeds to repurchase 500,000 shares of
Common Stock (the "RPI Shares") from a former stockholder of the Company. See
"Certain Transactions." The Company used an additional $945,000 of such net
proceeds to repay a portion of its bank debt, and expenses associated therewith.
The Company utilized the balance of the net proceeds of the Private Offerings
for the following purposes: for working capital; for the purchase of equipment;
for research and development expenses; and for registration of the Underlying
Shares pursuant to the Registration Statement of which this Prospectus is a
part.
 
                                USE OF PROCEEDS
 
    The Company will receive all of the proceeds from the exercise of the
Redeemable Warrants, the Bank Warrants and the Options. If all of the
outstanding Redeemable Warrants, Bank Warrants and Options are exercised, the
net proceeds to the Company will be approximately $1,500,000. The proceeds from
the exercise of the outstanding Redeemable Warrants, Bank Warrants and Options,
if any, will be used to pay the expenses of this Offering, which are being borne
by the Company, and the remainder will be added to the Company's working
capital.
 
    The Company will not receive any of the proceeds from the sale of the shares
of Common Stock being offered hereby (including the Underlying Shares) by the
Selling Securityholders.

    There were approximately 1,150 holders of record of the Common Stock as of
April 25, 1996. This number, however, does not reflect the ultimate number of
beneficial holders of the Company's Common Stock.
 
    In April 1995, the Exchange halted trading in the Common Stock because the
Company had not fully satisfied the Exchange's financial guidelines for
continued listing of the Common Stock. Although trading resumed on May 16, 1995,
there is no assurance that such listing will continue. See "Risk Factors."
 
    The Company does not expect to declare or pay any cash or stock dividends in
the foreseeable future. Certain of the Company's debt instruments prohibit the
payment of cash dividends. The payment of dividends, if any, in the future is
within the discretion of the Board of Directors and will depend on the Company's
earnings, its capital requirements and financial condition, the agreement of
holders of the aforementioned debt instruments, and other relevant factors.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
GENERAL
 
    Sales for the year ended December 31, 1995 were approximately $20,000,000 as
compared to sales of approximately $24,000,000 for 1994. The net loss for the
year ended December 31, 1995 was $2,200,000 or $.28 per share, compared with the
net loss of $5,700,000 or $.80 per share for 1994.
 
    For the year ended December 31, 1995, the reduction in sales was primarily
attributable to the reduction in shipments of tablet products due to the sale at
the end of the first quarter by the Company of the Tablets ANDA to Mallinckrodt
which is partially offset by manufacturing revenue that the Company is receiving
as part of its agreement with Mallinckrodt. In addition, the decrease is
attributable to price reductions effected during the year in order to meet
increased competition in the market. Depreciation and amortization was
approximately $1,956,000 in 1995 as compared to $2,350,000 for 1994.
 
    For the year ended December 31, 1994, the reduction in sales was primarily
attributable to the FDA consent decree of June 29, 1993, which resulted in lower
sales from July 1993 to December 31, 1994. The net credits issued for recalled
products in excess of previous estimated reserves for returns was approximately
$740,000. Cost of Goods Sold includes inventory write-offs in excess of
estimated reserves for inventory of recalled products (approximately $440,000).
Depreciation and amortization was approximately $2,350,000 in 1994 as compared
to $2,104,000 for 1993. The year ended December 31, 1994 had no benefit
available for carryback to prior years as a result of the prior year 1993
carryback utilizing the available tax benefit of $2,500,000.
 
    On June 21, 1993, the Company entered into a plea agreement with the DOJ
pursuant to which the Company agreed to plead guilty to five counts of
adulteration of a single drug product and related record keeping violations. The
Company also agreed to pay a fine in the amount of $2,500,000, payable in
quarterly installments of $125,000 over five years commencing on September 15,
1993.
 
    On June 29, 1993, the Company entered into a consent decree with the U. S.
Attorney for the Eastern District of New York on behalf of the FDA as a result
of the FDA's investigation into the manufacturing and record keeping practices
at the Company's Brooklyn plant.
 
    See "Legal Proceedings" for additional information regarding the plea
agreements with the DOJ and the consent decree on behalf of the FDA.
 
    During 1994, the Company completed the validation of the five solid dosage
products required by the FDA consent decree in 1994. The Company also completed
validation of certain liquid products at the Brooklyn plant. The Company is
currently in the process of completing validity assessment studies and preparing
validation protocols for products with plans to re-introduce the products in the
near future.
 
OUTLOOK
 
    During 1996, the Company intends to focus its research and development
program primarily on the reintroduction of certain previously discontinued
products as well as the development of new generic pharmaceuticals. See
"Business--Research and Development." Moreover, as a result of the consent
decree, the Company is conforming the operations of its Brooklyn plant to the
FDA's CGMP regulations and to satisfy the conditions for the resumption of
shipments of the five products permitted under the consent decree. For the
fiscal years ended December 31, 1995, 1994 and 1993, these five solid dosage
products accounted for approximately $12,400,000, $15,275,000 and $17,729,000 of
sales or 61%, 63% and 49.2% of the total sales for the Company, respectively.
 
                                       16
<PAGE>
    For the fiscal year ended December 31, 1993, Hydrocodone Bitartrate and
Acetaminophen Tablets ("HBA") (shipments of which have not been resumed as a
result of the validation process) accounted for approximately $2,922,000 or 8.1%
of the total sales of the Company. There were no shipments of this product after
June 29, 1993. The Company wrote off inventory of HBA of approximately
$1,000,000 during 1993. There can be no assurance that the Company will be able
to achieve prior levels of sales of this products in future periods, or that the
Company's current product mix will enable the Company to return to
profitability. As a result of the substantial reduction in the number of
products manufactured at the Brooklyn plant, however, and as part of the
Company's continuing efforts to reduce operating costs at the Brooklyn plant,
the Company has achieved substantial workforce reductions, which management
estimates will result in annual savings of approximately $4,500,000. As a result
of the foregoing, the historical results of operations reflected in the
condensed consolidated financial statements may not be indicative of future
operating results.
 
    As a result of problems identified at H.R. Cenci Laboratories, Inc.
("Cenci"), a 51%-owned subsidiary of the Company, new management conducted an
internal review of its operations. This review led Cenci to discover
irregularities which prompted it to cease all manufacturing operations and to
replace certain key personnel. Cenci has had ongoing discussions with officials
of the FDA. Cenci has cooperated with requests from the U.S. Department of
Justice/U.S. Attorney for the District of Maryland ("USDOJ/USADM") in its
investigation into the practices of certain of Cenci's former employees while
they were acting on behalf of Cenci. In addition, several current employees have
appeared before the grand jury and or spoken with representatives of the
USDOJ/USADM. In October 1995 the former regulatory affairs director for Cenci
pleaded guilty to making false statements to the FDA. In December 1995 this
individual was sentenced. At this time, the Company is unable to predict what
other consequences, if any, will result from the USDOJ/USADM's investigation.

NET SALES
 
    The Company's net sales for the fiscal year ended December 31, 1995 of
$20,225,000 represents a decrease by $3,957,000 as compared to net sales for the
fiscal year ended December 31, 1994. The decrease in 1995 is primarily
attributable to the sale of the Tablets ANDA to Mallinckrodt. Also, in 1995 the
decrease in sales is attributable to price reductions implemented in order to
meet increased market competition. In 1994, the Company's net sales decreased by
$11,842,000 as compared to 1993. The decrease in 1994 is primarily attributable
to the discontinuance of certain solid dosage products as a result of the June
1993 consent decree on behalf of the FDA. In addition, the Company decided to
suspend shipments of liquid products of Cenci for the last six months of 1994
and in 1995. This suspension of shipments contributed to the decline in net
sales during 1994. Also impacting 1994 sales are credits issued for recalled
products which exceeded the estimated reserves established at December 31, 1993
by approximately $740,000.
 
                                       18
<PAGE>
COST OF GOODS SOLD
 
    For 1995, cost of goods sold decreased by approximately $3,598,000 as
compared to 1994, and in 1994 by approximately $7,476,000 as compared to 1993.
The decrease for 1995 is primarily attributable to the reduction in shipments of
tablet products due to the sale by the Company of the Tablets ANDA combined with
significant reductions in manufacturing costs of personnel and other expenses.
However, these reductions were partially offset by increased raw material costs
during the year. The decrease for 1994 is primarily attributable to the
reduction in units produced and the suspension of shipments of certain solid
dosage products. In addition, in 1994, the suspension of shipments of certain
liquid products of Cenci as a result of the Company's review of operations at
this location and at the Brooklyn plant, resulted in the write-off of inventory
for recalled products in excess of the reserve in the amount of approximately
$440,000. Management effected certain cost saving measures such as reducing
personnel and other expenditures during 1995. The Company's gross margin as a
percentage of sales for the fiscal years ended December 31, 1995, 1994 and 1993
was 12.1%, 11.6% and 20.0%, respectively.
 
SELLING, GENERAL AND ADMINISTRATIVE EXPENSES
 
    Selling, general and administrative expenses as a percentage of sales for
the fiscal years 1995, 1994 and 1993 were 28.7%, 28.6% and 24.4%, respectively.
These expenses decreased by approximately $1,118,000 or 16.0% in fiscal year
1995 as compared to 1994. The decrease in both years was attributable to cost
saving measures effected by management during each year, coupled with a decrease
in net sales.
 
COST OF TEMPORARY CLOSING OF FACILITY
 
    As as a result of irregularities identified in the manufacturing operations
of Cenci, the Company, in July 1994, ceased all sales activities at Cenci. Upon
completion of its review and modifications at the facility, the Company reopened
Cenci in January 1996. In connection with this temporary closure, the Company
recorded costs of $615,000 and $427,000 for the years ended December 31, 1995
and 1994, respectively. These costs consist of inventory writeoffs, utilities,
security and rent.
 
PROVISION FOR STOCKHOLDERS LITIGATION
 
    In June 1994, the Company and the plaintiffs in certain class actions and
shareholder derivative lawsuits agreed to settle the litigations. In June 1994,
the Company agreed to a settlement of these lawsuits. In November 1994, both the
Federal and State Courts approved the terms of the settlement, under which the
Company agreed to pay $1,000,000 in cash and, at the Company's option, either
(i) to issue shares of Common Stock having an aggregate market value, as of the
date of distribution, of $3,000,000, or (ii) to pay $3,000,000 in cash, or (iii)
to distribute any combination of shares or cash having a combined value as of
the date of distribution of $3,000,000. The initial payment of $1,000,000 was
paid by the Company's insurers. In November 1995 the Company paid the remainder
of the settlement fund by the issuance of 824,742 shares of Common Stock at a
per share price of $3.6375, or an aggregate value of $3,000,000. The Company had
previously recorded an estimated provision of $3,000,000 in the fourth quarter
of 1993 as the estimated cost to settle the above shareholder actions.
 
INTEREST EXPENSE
 
    Interest expense for 1995 increased by $572,000 as compared to 1994 as a
result of fees payable to the Company's banks, an increase in the level of
borrowings due to the issuance of convertible subordinated debentures and an
increase in the interest rate after the second quarter of 1994 (see "Liquidity
and Capital Resources" below). Interest expense for 1994 increased by $104,000
as
 
                                       19
<PAGE>
compared to 1993 as a result of an increase in the prime rate in 1994 and an
increase in the margin rate in mid-1993 applicable to the Company's borrowings.
 
(BENEFIT) PROVISION FOR INCOME TAXES
 
    The Company had no tax (benefit) provision for 1995 and 1994 since the
available loss carryback to prior years was utilized by the net operating loss
for 1993 carryback to the prior three years. In 1993 the Company's effective tax
benefit rate was approximately 19.2% as compared to an effective income tax rate
of 55.8% in fiscal year 1992. The benefit rate in 1993 arose as a result of a
net operating loss carryback to the preceding three years and is attributable to
the lack of tax benefit of subsidiary losses combined with the nondeductibility
of the DOJ settlement.
 
NET LOSS
 
    For 1995, the Company had a net loss of $2,203,000 as compared to a net loss
of $5,767,000 for 1994. The decrease in net loss is attributable to the gain on
the sale of assets of $4,188,000 net of the tax provision of $296,000, or
$3,892,000. The net loss for 1994 of $5,767,000 represents a decrease in the
amount of loss of $5,136,000 as compared to the net loss for 1993 of
$10,903,000. The loss in 1994 is primarily attributable to the suspension of
shipments of certain solid dosage products as part of the aforementioned consent
decree in June 1993 combined with the suspension of shipments of liquid products
at the subsidiary for the second half of the year.
 
LIQUIDITY AND CAPITAL RESOURCES
 
    At December 31, 1994, the Company had cash and cash equivalents of $353,000
as compared to $28,000 at December 31, 1993. The Company had a working capital
deficiency at December 31, 1995 of $7,393,000.
 
    The Company consummated the Private Offerings in July 1995 and November
1995.
 
    The net proceeds of the Private Offerings were approximately $7,013,000. The
Company utilized $1,100,000 of such proceeds to repurchase 500,000 shares of
Common Stock (the "RPI Shares") from a former stockholder of the Company. The
Company used an additional $945,000 of such net proceeds to repay a portion of
its bank debt. The Company intends to utilize the balance of the net proceeds of
the Private Offerings for the following purposes: for working capital; for the
purchase of equipment; for research and development expenses; and for the
registration of the Underlying Shares under the Securities Act. See "The Private
Offerings."
 
    As a result of the decline in shipments of solid dosage products from the
Company's Brooklyn plant following the entry of the consent decree, and as a
result of the lack of available borrowings under the Company's credit agreement,
the Company's liquidity position has been materially adversely affected since
June 30, 1993 and the Company's capital resources have been severely limited.
The Company has actively sought to reduce its operating costs at the Brooklyn
plant, where it has made significant reductions in personnel.
In addition, the Company's liquidity position has been affected during
the second half of 1994 by the discontinuance of shipments of liquid products
from its Cenci subsidiary as a result of review completed by the Company of this
liquid operation. In an effort to reduce the loss from lower revenues at this
subsidiary, the Company has reduced its operating costs at Cenci through
significant reductions of personnel and other expenses.
 
    Under the terms of the plea agreement with the DOJ, the Company has agreed
to pay a $2,500,000 fine, payable in quarterly installments of $125,000 over
five years. Two installments have been paid to date. Only additional partial
payments have been paid in the amount of $90,000. The agreement with the DOJ
stipulates if any payments are not made in a timely fashion, the entire amount
of the fine shall become due and payable immediately. As a result, the entire
outstanding amount of the settlement has been
 
                                       20
<PAGE>
classified as current as of December 31, 1994. As of the current date, no action
has been initiated to require immediate payment of the entire amount; however,
the Company has recently made several partial payments.
 
    In March 1995, the Company and its banks restructured the Company's amended
credit agreement to include an extension of the due date to August 31, 1995,
modification of the financial covenants, reduction of the exercise prices of all
warrants granted to the banks in excess of $2.375 per share to $2.375 per share
and extension of the expiration date of the warrants to December 1999. As
consideration for these modifications, the banks received $1,500,000 of the
proceeds received from the transaction with Mallinckrodt. Funds have been
applied to reduce outstanding principal by approximately $1,113,000 to
approximately $3,777,000, to pay accrued interest (approximately $154,000) and
fees (approximately $233,000). In addition, if the outstanding borrowings were
not repaid by August 31, 1995, the Company has been required to pay an
additional 3% ($102,000) of the then outstanding principal due to the banks.
Such amount has been accrued.
 
    In July 1995, the Company and its banks (the "Banks") amended the credit
agreement as a result of the consummation of the July Private Offering. As
consideration for waiving any breach or default under the Credit Agreement as a
result of the July Private Offering, the Banks received $500,000 of the proceeds
as payment for interest, fees and principal and an extension of the warrant
exercise period to July 17, 2000. The Banks now hold warrants to purchase
635,653 shares of the Company's Common Stock at prices ranging from $2.13 to
$2.275, with an average weighted exercise price of $2.26.
 
    The credit agreement with the Banks expired in March 1996. Although
management hopes to negotiate an extension of the credit agreement, there can be
no assurance that such an extension will be agreed to.
 
    On March 21, 1995, the Company sold its Tablets ANDA for 5mg Oxycodone
HCl/325mg Acetaminophen tablets and certain pieces of equipment utilized in
connection with the production activities under the Tablets ANDA for up to $5.4
million to Mallinckrodt. Mallinckrodt paid the Company $2 million of the
purchase price on the closing date, having previously paid $500,000 in July
1994. The balance of the purchase price is payable as follows: Mallinckrodt will
pay $1 million when the Company receives general clearance from the FDA for
unrestricted operations at it facility in Brooklyn, New York and written notice
from the FDA that it is in compliance with certain provisions of the consent
order dated July 9, 1993. Mallinckrodt will pay the Company $1.9 million balance
of the Deferred Payment when Mallinckrodt receives certain authorizations from
the FDA, but in no event later than September 21, 1997. See
"Business-Dispositions" for additional information regarding this transaction.
 
    On March 30, 1995, the Company signed the Zatpack Agreement with Zatpack
which provides for the purchase of 500,000 shares of Common Stock of the Company
by Zatpack in consideration of $1,000,000. See "Business-Other
Transactions--Agreements with Zatpack, Inc." for additional information
regarding the Zatpack Agreement.
 
    As previously indicated, the Company has continued to actively pursue
financing. At the current time, the Company is discussing with several parties
obtaining financing which will replace the Company's banks and provide
additional working capital. There can be no assurance that the Company will be
able to obtain any such financing on commercially acceptable terms.
 
CAPITAL EXPENDITURES
 
    The Company's capital expenditures during 1995, 1994 and 1993 were $536,000,
$216,000 and $1,688,000, respectively. The decrease in capital expenditures in
1995 and 1994 as compared to 1993 is attributable to the Company's cash
conservation measures.

                                    BUSINESS
 
GENERAL
 
    Halsey, a New York corporation established in 1935, and its subsidiaries,
are engaged in the manufacture, sale and distribution of generic drugs. A
generic drug is the chemical and therapeutic equivalent of a brand-name drug for
which patent protection has expired. A generic drug may only be manufactured and
sold if patents (and any additional government-granted exclusivity periods)
relating to the brand-name equivalent of the generic drug have expired. A
generic drug is usually marketed under its generic chemical name or under a
brand name developed by the generic manufacturer. The Company sells its generic
drug products under its Halsey label and under private-label arrangements with
drugstore chains and drug wholesalers. While subject to the same governmental
standards for safety and efficacy as its brand-name equivalent, a generic drug
is usually sold at a price substantially below that of its brand-name
equivalent.
 
    Halsey's wholly-owned subsidiaries include Blue Cross Products, Inc., a New
York corporation (currently inactive), Houba, Inc. ("Houba"), an Indiana
corporation, Halsey Pharmaceutical, Inc. ("Halsey Pharmaceutical"), a Delaware
corporation, The Medi-Gum Corporation, a Delaware corporation (currently
inactive), and Indiana Fine Chemicals Corporation ("Indiana Chemicals"), a
Delaware corporation. Halsey has two additional subsidiaries: Cenci, a
California corporation (51% owned), and Cenci Powder Products, Inc. ("Cenci
Powder"), a Delaware corporation (51% owned).
 
    The Company manufactures its products at facilities in New York, Indiana and
California. During 1995, in connection with the sale of its Oxycodone with
Acetaminophen Tablet business, the Company began manufacturing Oxycodone with
Acetaminophen Tablets for a third party. See "Business--Dispositions," below.
During the last several years, the Company has sought to diversify its
businesses through strategic acquisitions and through the development,
manufacture and sale of bulk chemical products used by others as raw materials
in the manufacture of finished drug forms. The Company's ability to develop and
manufacture bulk chemical products was enhanced by the acquisition in 1990 of
100% of the capital stock of Houba and the completion by Houba in late 1991 of a
new 15,000-square-foot manufacturing facility. Houba currently produces and
markets raw materials intended for pharmaceutical and food supplements, as well
as solid dosage forms of generic drug products. In October and December 1991,
the Company acquired majority interests in Cenci and Cenci Powder, respectively.
These acquisitions gave the Company a greater presence on the West Coast of the
United States, and added new products. Cenci and Cenci Powder manufacture liquid
and powder preparations, respectively, of pharmaceutical products in various
dosage forms. The Company's Indiana Chemicals subsidiary is engaged in the
manufacture of the specialty vitamin Biotin. Halsey Pharmaceutical is a trading
company engaged exclusively in sales operations.
 
    During the past several years, the Company's business has been adversely
affected by the discovery of various manufacturing and record keeping problems
identified with certain products manufactured at its Brooklyn, New York plant.
These problems caused the Company to halt production and sale of a number of
products and to establish a $2,000,000 reserve as of December 31, 1992, and a
reserve of $3,875,000 in 1993 to cover estimated costs associated with inventory
write-offs, recalls of the affected products and estimated additional legal
expenses. The affected products accounted for approximately 28% of the Company's
total revenues in each of 1992 and 1993. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations--General."
 
    On June 21, 1993, the Company entered into a plea agreement with the DOJ to
resolve the DOJ's investigation into the manufacturing and recordkeeping
practices at the Company's Brooklyn plant. Under the terms of the plea
agreement, the Company agreed to plead guilty to five counts of adulteration of
a single drug product shipped in interstate commerce and related recordkeeping
violations. The plea agreement also requires the Company to pay a fine of
$2,500,000 over five years in quarterly installments of $125,000 commencing in
September 1993. Two installments have been paid to date. Only additional partial
payments have been paid in the amount of $90,000. The agreement with
 
                                       22
<PAGE>
the DOJ stipulates that if any payments are not made in a timely fashion the
entire amount of the fine shall become due and payable immediately. Such
nonpayment also constituted a default under the Company's Credit Agreement with
its banks (which has expired). As a result, the entire amount of the settlement
has been classified as current. As of the date of this Prospectus, no action has
been initiated to require payment of the entire outstanding amount of the fine.
 
    On June 29, 1993, the Company entered into a consent decree with the U.S.
Attorney for the Eastern District of New York on behalf of the FDA that resulted
from the FDA's investigation into the Brooklyn plant's compliance with the FDA's
CGMP regulations. Under the terms of the consent decree, the Company was
enjoined from shipping any solid dosage drug products (i.e., excluding liquid
drug formulations) manufactured at the Brooklyn plant until the Company
established, to the satisfaction of the FDA, that the methods used in, and the
facilities and controls to be used for, manufacturing, processing, packing,
labeling and holding any drug, are established, operated, and administered in
conformity with the Federal Food, Drug, and Cosmetic Act and all CGMP
regulations. As part of satisfying these requirements, the Company is required
to validate the manufacturing processes for each solid dosage drug product prior
to manufacturing and shipping the drug product. The Company, however, was
permitted under the terms of the consent decree to manufacture and ship from the
Brooklyn plant six identified solid dosage drug products, the Brooklyn Solid
Dosage Products, at its own risk provided that: (i) at least twice per month,
the Company's independent expert certifies that each batch of drug product upon
validation will have been manufactured in accordance with the CGMP Regulations
and the formulation described in the drug product's approved New Drug
Application ("NDA") or ANDA, until such time as validation is completed for
these products; and (ii) for any batches of these products that have already
been manufactured, such certification will include a certification by a Company
representative with personal knowledge of the records relating to such drug that
such records are accurate and complete and a certification signed by an
independent expert that he has personally reviewed the records, and that in his
professional opinion the foregoing requirement concerning validation has been
met.
 
    At the beginning of August 1993, the Brooklyn plant resumed shipments of two
drug products (Class II narcotics), Oxycodone with Acetaminophen Capsules
5mg/500mg and Oxycodone with Acetaminophen Tablets 5mg/325mg, and thereafter
resumed shipments of a third solid dosage drug product, Acetaminophen,
Butalbital and Caffeine Tablets 325mg, 50mg, 40mg. During 1995, the Company sold
its Oxycodone with Acetaminophen Tablet business to Mallinckrodt. Under a
tolling arrangement with Mallinckrodt, the Company will continue to manufacture
such tablets for Mallinckrodt for at least two years. See
"Business--Dispositions," below. In September 1993, the Company resumed
shipments of two other solid dosage drug products, Isoniazid 300mg and
Tetracycline 250mg and 500mg capsules, from the Brooklyn plant. After review by
the Company of one of the Brooklyn Solid Dosage Products which the Company was
permitted to continue to manufacture and ship under the terms of the consent
decree, Hydrocodone Bitartrate 5mg and Acetaminophen 500mg Tablets,
discrepancies were discovered with some of the data in the Company's ANDA. This
resulted in a voluntary recall of this product in November 1993 and the
withdrawal of the ANDA. As a result of such recall and the transaction with
Mallinckrodt the Company manufactures and ships four solid dosage products from
its Brooklyn plant on its own behalf and manufactures one solid dosage product
on behalf of Mallinckrodt.
 
PRODUCTS AND PRODUCT DEVELOPMENT
 
  Generic Drug Products
 
    The Company historically has manufactured and sold a broad range of
prescription and over-the-counter drug products. The Company's pharmaceutical
product list currently includes a total of approximately 31 products, consisting
of 20 dosage forms and strengths of prescription drugs and 11 dosage forms and
strengths of over-the-counter drugs. Each dosage form and strength of a
particular
 
                                       23
<PAGE>
drug is considered in the industry to be a separate drug product. The Company's
drug products are sold in various forms, including liquid and powder
preparations, compressed tablets and two-piece, hard-shelled capsules.
 
    Most of the generic drug products manufactured by the Company can be
classified within one of the following categories:
 
       1. Antibiotics,
 
        2. Anti-infective and anti-tubercular drugs,
 
        3. Neuropharmacological drugs,
 
        4. Antihistamines and antihistaminic decongestants, or
 
        5. Antitussives.
 
    In October 1991, the FDA suspended review of all of Halsey's (but not
Houba's or Halsey's other subsidiaries') applications for new drug approvals. It
is unlikely that Halsey will receive any new approvals to market any generic
drugs from the FDA in 1996. See "Government Regulation" below.
 
    The Company's development strategy for new drug products has been to focus
on the development of a broad range of generic form drugs, each of which (i) has
developed a solid market acceptance with a wide base of customers, (ii) can be
sold on a profitable basis notwithstanding intense competition from other drug
manufacturers, and (iii) is no longer under patent protection. The Company has
also diversified its current product line to include some less widely prescribed
drugs as to which limited competition might be expected. As a result of the FDA
consent decree, the Company's strategy at the Brooklyn plant has been to
concentrate on conforming the operations of the plant to the FDA's CGMP
regulations and to satisfy the conditions for the resumption of shipments of the
remaining four Brooklyn Solid Dosage Products described above. However, during
1996, the Company, through its Houba subsidiary, may continue to apply for ANDA
approvals. In addition, the Company will continue to pursue the development of
its existing pharmaceutical business as well as the development of Houba's
chemical products business.
 
    Development activities for each new generic drug product begin several years
in advance of the patent expiration date of the brand-name drug equivalent. This
is because the profitability of a new generic drug usually depends on the
ability of the Company to obtain FDA approval to market that drug product upon
or immediately after the patent expiration date of the equivalent brand-name
drug so that the Company will be among the first to market the new generic drug
product. As other off-patent drug manufacturers receive FDA approvals on
competing products, prices and revenues typically decline. Accordingly, the
Company's ability to attain its previous levels of profitability depends on the
Company's ability to develop and introduce new products, the resumption of FDA
review of Halsey's application for new drug approvals at its Brooklyn plant, the
timing of FDA approval of such products and the number and timing of FDA
approvals for competing products.
 
  Bulk Chemical Products
 
    In the last few years, the Company has increased its efforts to develop,
manufacture and market bulk chemical products. The development and sale of bulk
chemicals is generally not subject to the same level of regulation as is the
development and sale of drug products; accordingly, chemicals may be brought to
market substantially sooner than drug products.
 
  Dispositions
 
    On March 21, 1995 (the "Closing Date"), the Company sold its Tablets ANDA
for 5 mg Oxycodone HCl/325 mg Acetaminophen tablets ("Tablets"), and certain
pieces of equipment utilized in connection with its production activities under
the Tablets ANDA for up to $5.4 million (the
 
                                       24
<PAGE>
"Purchase Price") to Mallinckrodt. Mallinckrodt paid the Company $2 million of
the Purchase Price on the Closing Date, having previously paid $500,000 in July
1994. The balance (the "Deferred Payment") of the Purchase Price is payable as
follows. Mallinckrodt will pay $1 million when the Company receives general
clearance from the FDA for unrestricted operations at its Brooklyn facility and
written notice from the FDA that the Company is in compliance with certain
provisions of the consent order dated July 2, 1993. Mallinckrodt will pay the
Company the $1.9 million balance of the Deferred Payment when Mallinckrodt
receives certain authorizations (the "Mallinckrodt Authorizations") from the
FDA, but in no event later than September 21, 1997.
 
    In connection with the transaction, Mallinckrodt agreed to defer $1.2
million of the Company's trade debt due to an affiliate of Mallinckrodt. The
deferred indebtedness is evidenced by a promissory note (the "Note") with
interest accruing at a rate of 8% per annum. The Note, which may be prepaid at
any time, is due and payable on the earlier of the date of the Mallinckrodt
Authorization or September 21, 1997. Mallinckrodt may offset its Deferred
Payment obligations against the amount due on the Note, provided certain
conditions are met. The Company may also offset the amount due to Mallinckrodt
on the Note against the Deferred Payment obligations when such obligations
mature. However, the Company has agreed with its banks (See "Management's
Discussion and Analysis of Financial Condition and Results of Operation") not to
exercise its right of offset until the Company has repaid in full the amounts
due to its banks. The Note, which is subordinate to future bank indebtedness of
up to $8,000,000, is secured by substantially all of the Company's and Houba's
assets.
 
    In connection with the sale of the Tablets ANDA, the Company agreed to
manufacture Tablets for Mallinckrodt for a period of three years and
Mallinckrodt agreed to order a minimum number of Tablets from the Company for
the two year period following the Closing Date. Mallinckrodt may terminate the
manufacturing agreement after two years. The Company and Mallinckrodt also
entered into a non-competition agreement pursuant to which the Company agreed
not to compete with Mallinckrodt and its affiliates in the United States with
respect to the Tablets ANDA until March 21, 2000.
 
    During the fiscal years ended December 31, 1994, 1993 and 1992, the Company
derived net revenues from Tablets of approximately $6,600,000, $5,600,000 and
$4,200,000, respectively. Management anticipated that Tablet sales would decline
during 1995 as a result of increasing competition. Management's determination
that an integrated supplier such as Mallinckrodt would be better suited to
increasingly competitive market conditions than the Company was an important
factor in the decision to proceed with the sale of the Tablets ANDA.
 
    In connection with the sale of the Tablets ANDA, the Company issued to
Mallinckrodt an option exercisable at any time until March 21, 1998, to purchase
the ANDA for acetaminophen/oxycodone capsules at an exercise price (the "Option
Price") equal to 75% of Net Capsule Revenue, subject to downward adjustment in
the event of a decline in pricing levels. Net Capsule Revenue is defined to mean
all revenue (net of rebates, adjustments, discounts, allowances, expenses
incurred in product recalls and similar items) derived from sales of
acetaminophen/oxycodone capsules during the twelve month period immediately
prior to the date the option is exercised. The Option Price is payable $200,000
as follows: $200,000 on the later of (i) exercise and (ii) the date when
Mallinckrodt or an affiliate qualifies as the new source for certain raw
materials, with the remainder of the Option Price due when Mallinckrodt obtains
certain authorizations from the FDA or such earlier date as the parties agree.
Upon exercise Mallinckrodt will purchase from the Company equipment used to
manufacture the capsules for the greater of $250,000 or the appraised value of
the equipment. At such time the Company and Mallinckrodt will enter into
agreements pursuant to which the Company will (a) manufacture
acetaminophen/oxycodone capsules for Mallinckrodt for a period of time and (b)
be prohibited from competing with Mallinckrodt and its affiliates with respect
to the production of capsules.
 
                                       25
<PAGE>
  Acquisitions
 
    The Company has engaged Penick Corporation ("Penick") to process certain of
the raw materials utilized in the production of acetaminophen/oxycodone
capsules. In order to ensure the continued viability of Penick, the Company's
Houba subsidiary purchased a 25% equity interest in Penick in mid-1993. In
addition, in September 1995, Houba purchased an 8.3% equity interest in Penick
Pharmaceutical, Inc., which owns the other 75% of Penick. In June 1994 both
Penick Corporation and Penick Pharmaceutical, Inc, filed petitions under Chapter
11 of the United States Bankruptcy Code. If Penick were to cease operations,
there can be no assurance that the Company would be able to enter into a
relationship with another entity licensed by the FDA to process such raw
materials on commercially acceptable terms.
 
OTHER TRANSACTIONS
 
  Agreements with Zatpack, Inc.
 
    On March 30, 1995, the Company signed an agreement (the "Zatpack Agreement")
with Zatpack, Inc. ("Zatpack"), an affiliate of Zuellig Group N.A., Inc.
("Zuellig"). The Zatpack Agreement provides for the purchase of 500,000 shares
of Common Stock (the "Zatpack Shares") by Zatpack, a British Virgin Islands
Company, in consideration of $1,000,000. The $1,000,000 purchase price was
comprised of a combination of cancellation of indebtedness (primarily incurred
by subsidiaries of Halsey for the purchase of raw materials previously delivered
and in the process of being delivered from affiliates of Zuellig), purchase of
inventory, and surrender of shares of Indiana Chemicals. The Zatpack Shares are
included in the Registration Statement of which this Prospectus is a part. As a
result of this transaction, the Company owns 100% of Indiana Chemicals.
 
    Pursuant to the Zatpack Agreement, the Company issued the Zatpack Note 
to Zatpack as consideration for cancellation of additional indebtedness. 
This indebtedness resulted from trade payables and advances to the Company 
by Zuellig and certain of its subsidiaries. The Zatpack Note is in the 
original principal amount of $1,292,242, with interest accruing at a rate 
of 8%, compounded annually. The Zatpack Note is convertible into Common Stock 
(the "Note Shares") at an adjusted conversion price of $2.39 per share, 
subject to further adjustment. The Zatpack Note is subordinate to all 
bank and institutional indebtedness of the Company, and may be prepaid 
by the Company, in whole but not in part, upon 30 days notice to the 
holders thereof without penalty. The Note Shares are included in the
Underlying Shares registered hereby.
 
    In connection with the transactions contemplated by the Zatpack Agreement, a
subsidiary of Zuellig agreed to supply a subsidiary of the Company with
Methacycline HCl for a three year period.
 
  Sale of Stock to Ranbaxy
 
    On October 27, 1994, the Company signed a Letter of Intent ("LOI") with
Ranbaxy Pharmaceuticals, Inc. ("RPI"), a wholly owned United States subsidiary
of Ranbaxy Laboratories Ltd. of New Delhi, India. The Company received $1
million from RPI in payment for 500,000 shares of Common Stock in accordance
with the terms of the LOI. The LOI provided for completion of due diligence by
RPI within a period of 30 days, after which the parties would negotiate and
finalize a definitive agreement. After execution of a definitive agreement, RPI
was to have purchased an additional 5,000,000 newly issued shares of Common
Stock for $10 million. On November 29, 1994, the Company announced that RPI had
decided not to proceed with its second purchase of the Company's Common Stock.
In August 1995, the Company repurchased the RPI Shares from RPI for an aggregate
purchase price of $1,100,000, which funds were derived from the proceeds of the
July Private Offering. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations" and "Certain Transactions."

GOVERNMENT REGULATION
 
  General
 
    All pharmaceutical manufacturers, including the Company, are subject to
extensive regulation by the federal government, principally by the FDA, and, to
a lesser extent, by state and local governments. The Company cannot predict the
extent to which it may be affected by legislative and other regulatory
developments concerning its products and the healthcare industry generally. The
Federal Food, Drug, and Cosmetic Act, the Generic Drug Enforcement Act of 1992,
the Controlled Substance Act and other federal statutes and regulations govern
or influence the testing, manufacture, safe labeling, storage, recordkeeping,
approval, pricing, advertising, promotion, sale and distribution of
pharmaceutical products. Noncompliance with applicable requirements can result
in fines, recall or seizure of products, criminal proceedings, total or partial
suspension of production, and refusal of the government to enter into supply
contracts or to approve new drug applications. The FDA also has the authority to
revoke approvals of new drug applications. Recent changes in FDA procedures have
increased the time and expense involved in obtaining ANDA approvals and in
complying with the FDA's CGMP standards. The ANDA drug development and approval
process now averages approximately two to five years. The approval procedures
are generally costly and time consuming.
 
    FDA approval is required before any "new drug," prescription or
over-the-counter, can be marketed. A "new drug" is one not generally recognized
by qualified experts as safe and effective for its intended use. Such general
recognition must be based on published adequate and well controlled clinical
investigations. Generally, a drug which is the generic equivalent of a
previously approved prescription drug will be treated as a new drug requiring
FDA approval. Furthermore, each dosage form of a specific generic drug product
requires separate approvals by the FDA. However, as discussed below, less costly
and time consuming approval procedures may be used for generic equivalents.
 
    Among the requirements for drug approval is that the prospective
manufacturer's methods must conform to the CGMPs. CGMPs apply to the
manufacture, receiving, holding and shipping of all drugs, whether or not
approved by the FDA. CGMPs must be followed at all times during which the drug
is manufactured. To ensure full compliance with the standards, some of which are
set forth in regulations, the Company must continue to expend time, money and
effort in the areas of production and quality control. Failure to so comply
risks delays in approval of drugs, disqualification from eligibility to sell to
the government, and possible FDA enforcement action such as an injunction
against shipment of the Company's products or the seizure of noncomplying drug
products, and/or, in serious cases, criminal prosecution. See also "Government
Regulation--FDA Investigations" below and "Legal Proceedings."
 
    In addition, products marketed outside the United States, but which are
manufactured inside the United States, are subject to certain FDA regulations,
as well as regulation by the country in which the products are to be sold.
 
    The Company also is governed by federal, state and local laws of general
applicability, such as those regulating working conditions. In addition, the
Company is subject, as are manufacturers generally, to various federal, state
and local environmental protection laws and regulations, including those
governing the discharge of materials into the environment. Compliance with these
laws is not expected to have any material effect upon the Company's capital
expenditures, earnings or competitive position.
 
  Drug Approvals
 
    There are currently three ways to obtain FDA approval of a new drug.
 
    1. New Drug Applications ("NDA"). Unless one of the procedures discussed in
paragraph 2 or 3 below is available, a prospective manufacturer must conduct and
submit to the FDA complete clinical studies to prove a drug's safety and
efficacy, in addition to the bioavailability and/or bioequivalence
 
                                       27
<PAGE>
studies discussed below, and must also submit to the FDA information about
manufacturing practices, the chemical make-up of the drug and labeling.
 
    2. Abbreviated New Drug Applications ("ANDA"). The Drug Price Competition
and Patent Term Restoration Act of 1984 (the "1984 Act") established the ANDA
procedure for obtaining FDA approval for those drugs that are off-patent or
whose exclusivity has expired and that are bioequivalent to brand-name drugs. An
ANDA is similar to an NDA, except that the FDA waives the requirement of
conducting complete clinical studies of safety and efficacy, although it may
require expanded clinical bioavailability and/or bioequivalence studies.
"Bioavailability" means the rate of absorption and levels of concentration of a
drug in the blood stream needed to produce a therapeutic effect.
"Bioequivalence" means equivalence in bioavailability between two drug products.
In general, an ANDA will be approved only upon a showing that the generic drug
covered by the ANDA is bioequivalent to the previously approved version of the
drug, i.e., that the rate of absorption and the levels of concentration of a
generic drug in the body are substantially equivalent to those of a previously
approved equivalent drug. The principal advantage of this approval mechanism is
that an ANDA applicant is not required to conduct the same preclinical and
clinical studies to demonstrate that the product is safe and effective for its
intended use.
 
    The 1984 Act, in addition to establishing the ANDA procedure, created new
statutory protections for approved brand-name drugs. In general, under the 1984
Act, approval of an ANDA for a generic drug may not be made effective until all
relevant product and use patents for the equivalent brand name drug have expired
or have been determined to be invalid. The only exceptions are situations in
which the ANDA applicant challenges the validity or applicability of the patent
and either the patentholder does not file suit or litigation extends more than
30 months after notice of the challenge was received by the patent holder. Prior
to enactment of the 1984 Act, the FDA gave no consideration to the patent status
of a previously approved drug. Additionally, under the 1984 Act, if specific
criteria are met, the term of a product or use patent covering a drug may be
extended up to five years to compensate the patent holder for the reduction of
the effective market life of that patent due to federal regulatory review. With
respect to certain drugs not covered by patents, the 1984 Act sets specified
time periods of two to ten years during which approvals of ANDAs for generic
drugs cannot become effective or, under certain circumstances, ANDAs cannot be
filed if the equivalent brand-name drug was approved after December 31, 1981.
 
    3. Alternative New Drug Applications. An alternative NDA procedure is
provided by the 1984 Act whereby the applicant may rely on published literature
and more limited testing requirements. That alternative seldom provides
advantages over the ANDA procedure, however, and is accordingly rarely used.
 
  Generic Drug Enforcement Act
 
    As a result of hearings and investigations concerning the activities of the
generic drug industry and the FDA's generic drug approval process, Congress
enacted the Generic Drug Enforcement Act of 1992 (the "Generic Drug Act"). The
Generic Drug Act confers significant new authority upon the FDA to impose
debarment and civil penalties for individuals and companies who commit certain
illegal acts relating to the generic drug approval process.
 
    The Generic Drug Act requires the mandatory debarment of companies or
individuals convicted of a federal felony for conduct relating to the
development or approval of any ANDA, and gives the FDA discretion to debar
corporations or individuals for similar conduct resulting in a federal
misdemeanor or state felony conviction. The FDA may not accept or review during
the period of debarment (one to ten years in the case of mandatory, or up to
five years in the case of permissive, debarment of a corporation) any ANDA
submitted by or with the assistance of the debarred corporation or individual.
The Generic Drug Act also provides for temporary denial of approval of generic
drug applications during the investigation of crimes that could lead to
debarment. In addition, in more limited circumstances, the
 
                                       28
<PAGE>
Generic Drug Act provides for suspension of the marketing of drugs under
approved generic drug applications sponsored by affected companies. The Generic
Drug Act also provides for fines and confers authority on the FDA to withdraw,
under certain circumstances, approval of a previously granted ANDA if the FDA
finds that the ANDA was obtained through false or misleading statements. The
Company has not been debarred as a result of the FDA investigation and
settlement and the consent decree with the FDA makes no provision therefor. The
Company does not know when the FDA will resume review of the Company's new drug
applications, but such review can begin after the FDA finds that the Company is
in compliance with CGMP regulations. To date, the FDA has not made such a
finding. See "Legal Proceedings--Government Consent Decrees."
 
  Healthcare Reform
 
    Several legislative proposals to address the rising costs of healthcare have
been introduced in Congress and several state legislatures. Many of such
proposals include various insurance market reforms, the requirement that
businesses provide health insurance coverage for all their employees,
significant reductions in the growth of future Medicare and Medicaid
expenditures, and stringent government cost controls that would directly control
insurance premiums and indirectly affect the fees of hospitals, physicians and
other healthcare providers. Such proposals could adversely affect the Company's
business by, among other things, reducing the demand, and the prices paid, for
pharmaceutical products such as those produced and marketed by the Company.
Additionally, other developments, such as (i) the adoption of a nationalized
health insurance system or a single payor system, (ii) changes in needs-based
medical assistance programs, or (iii) greater prevalence of capitated
reimbursement of healthcare providers, could adversely affect the demand for the
Company's products.
 
  FDA Investigations
 
    In April and May of 1990, the FDA conducted a pre-approval inspection of the
Company's Brooklyn plant, certain pending ANDAs relating to one drug product (in
four dosages) and the Company's compliance with the CGMPs. The FDA issued
Inspectional Observations concerning, and made further investigation of, the
Company's recordkeeping practices and the accuracy of certain research and
development stage batch records maintained by the Company for one drug product.
As a result, the Company voluntarily withdrew the pending ANDAs relating to this
product, and shortly thereafter for one other product, which have never been
marketed by the Company. At that time, the FDA also inspected ten then currently
marketed drug products (23 dosages) and issued no Inspectional Observations with
respect to such products.
 
    In late 1991, the Company was notified that the FDA had undertaken a
validity assessment, pursuant to which the FDA suspended review of all of
Halsey's new drug applications, including four pending ANDAs. At the FDA's
suggestion, the Company voluntarily undertook an internal audit and retained an
outside consultant to review pending and various filed and approved ANDAs, the
results of which were provided to the FDA. Based on this initial review, the
Company voluntarily withdrew in 1991 three ANDAs for the drug fenoprofen
calcium.
 
PRODUCT RECALLS
 
    In March 1993, the Company stopped production and sale of five products
previously manufactured at the Company's Brooklyn plant as a result of various
problems identified with these products, which related primarily to the addition
of unapproved inactive ingredients, processing deviations and recordkeeping
discrepancies. The disclosures regarding the affected products, Quinidine
Gluconate, Propylthiouracil, Acetaminophen with Codeine, Propoxyphene Napsalate
with Acetaminophen and Metronidazole, resulted from investigations by the
Company, the FDA and DOJ into the Company's existing and pending ANDA drug
approvals and recordkeeping practices.
 
                                       29
<PAGE>
    In response to these problems, the Board of Directors adopted, and informed
the FDA that the Board would enact, a series of measures designed to address the
specific problems identified with the affected products and to avoid the
recurrence of similar problems. The Company notified the FDA that the Company
had indefinitely suspended the manufacture and sale of the affected products,
and that it had initiated a recall of those products from distributors and
retail sellers. In addition, the Company agreed to withdraw its ANDAs for
Propoxyphene Napsalate with Acetaminophen. A number of personnel and related
changes at the Brooklyn plant were instituted as part of the plan proposed to
the FDA directed at the Company's oversight of regulatory affairs. The plan
proposed to the FDA called for, among other things, the hiring of new
supervisors in the production department at the Brooklyn plant, including a new
head of production. The Company also extended its internal audit of the
Company's products at the Brooklyn plant to determine if any other problems
existed and to determine the causes of the identified problems. The Company
retained an additional qualified outside consultant to assist the Company's then
current outside consultant.
 
    In June 1993, the Company entered into a plea agreement with the DOJ and a
consent decree with the U.S. Attorney for the Eastern District of New York on
behalf of the FDA with respect to the DOJ and FDA investigations of the Company.
As a direct result of the consent decree and a subsequent product recall, the
Company is limited to manufacturing and shipping five identified solid dosage
drug products from its Brooklyn plant (the consent decree does not affect the
Company's ability to manufacture and ship liquid dosage drug products or affect
the Company's operations in its Indiana or California facilities), one of which
is being manufactured on behalf of Mallinckrodt. The Company has charged an
aggregate of approximately $5,935,000 to operations with respect to the plea
agreement and the consent decree. This amount was comprised of inventory
write-offs, product recalls and fines. See "Legal Proceedings--Government
Consent Decrees" and "Management's Discussion and Analysis of Financial
Condition and Results of Operations."
 
RESEARCH AND DEVELOPMENT
 
    The Company conducts research and development activities at each of its
Brooklyn and Indiana facilities. The Company's research and development
activities consist primarily of new generic drug product development efforts and
manufacturing process improvements, as well as the development for sale of new
chemical products. New drug product development activities are primarily
directed at conducting research studies to develop generic drug formulations,
reviewing and testing such formulations for therapeutic equivalence to brand
name products and additional testing in areas such as bioavailability,
bioequivalence and shelf-life. For fiscal years 1995, 1994 and 1993, total
research and development expenditures were $818,000, $491,000 and $2,140,000,
respectively. During 1996 the Company intends to concentrate its research and
development efforts in the following areas:
 
        1. Reintroduction of products suspended as a result of the consent
    decree which require prior FDA validation;
 
        2. Reintroduction of products which will require changes in formulation
    and submission for prior approval from the FDA;
 
        3. Reintroduction of the products withdrawn in 1993 and resubmission of
    the related ANDAs to the FDA; and
 
        4. Development of new products.
 
    There can be no assurance that the FDA will grant the requisite approvals
for any such product introductions.
 
    The Company currently maintains a full-time staff of eight in its Research
and Development Departments.
 
                                       30

MARKETING AND CUSTOMERS
 
    A key element of the Company's marketing strategy is to maintain sufficient
raw material and finished good inventories to enable the Company to fill
customer orders promptly. This strategy requires a substantial amount of working
capital to maintain inventories at a level sufficient to meet anticipated
demand.
 
    The Company sells its products primarily through three salaried employees
and to a lesser extent through two independent sales representatives, each of
whom are compensated on a commission basis. Sales of drugs in dosage form are
made primarily to drug wholesalers, drugstore chains, distributors and other
manufacturers and are not concentrated in any specific region.
 
    During 1995, the Company had net sales to two customers in excess of 10% of
total sales, each aggregating 25% and 11% of total sales, respectively. During
1994, the Company had net sales to three customers in excess of 10% of total
sales, each aggregating 12% of total sales. During 1993, the Company had net
sales to two customers in excess of 10% of total sales, each aggregating 12% of
total sales. Balances due from these customers were approximately 25% and 7% of
total accounts receivable at December 31, 1995 and 1994, respectively. The
Company believes that the loss of either of these customers could have a
material adverse effect on the Company.
 
    The estimated dollar amount of the backlog of orders for future delivery as
of March 28, 1996 was approximately $1,070,000 as compared with approximately
$5,000,000 as of March 31, 1995. Although these orders are subject to
cancellation, management expects to fill substantially all orders as of March
28, 1996 during the second quarter of 1996.
 
COMPETITION
 
    The Company competes in varying degrees with numerous companies in the
health care industry, including other manufacturers of generic drugs (among
which are divisions of several major pharmaceutical companies) and manufacturers
of brand-name drugs. Many of the Company's competitors have substantially
greater financial and other resources and are able to expend more money and
effort than the Company in areas such as marketing and product development.
Although a company with greater resources will not necessarily receive FDA
approval for a particular generic drug before its smaller competitors,
relatively large research and development expenditures enable a company to
support many FDA applications simultaneously, thereby improving the likelihood
of being among the first to obtain approval of at least some generic drugs.
 
    One of the principal competitive factors in the generic pharmaceutical
market is the ability to introduce generic versions of brand-name drugs promptly
after a patent expires. The Company believes that it will be at a competitive
disadvantage until the FDA resumes review of ANDAs submitted by the Company's
Brooklyn plant. See "Government Regulation--Generic Drug Enforcement Act" above.
Other competitive factors in the generic pharmaceutical market are price,
quality and customer service (including maintenance of sufficient inventories
for timely deliveries).
 
RAW MATERIALS
 
    The raw materials essential to the Company's business are bulk
pharmaceutical chemicals purchased from numerous sources. Raw materials are
generally available from several sources. During 1995, the Company purchased
approximately $2,741,000 of its raw materials (constituting 38.4% of its
aggregate purchases of raw materials) from Mallinckrodt, and as of December 31,
1995 more than 29.7% of the Company's trade payables was owed to this supplier.
If the Company became unable to continue to purchase raw materials from this
supplier, there can be no assurance that the Company will not face difficulties
in obtaining raw materials on commercially acceptable terms, which could have a
material adverse effect on the Company. See "Management's Discussion and
Analysis of Financial
 
                                       31
<PAGE>
Condition and Results of Operations--Liquidity and Capital Resources." The
federal drug application process requires specification of raw materials
suppliers. If raw materials from a supplier specified in a drug application were
to become unavailable on commercially acceptable credit terms, FDA supplemental
approval of any new supplier would be required. In view of the FDA consent
decree and the suspension of review of the Company's ANDAs by the FDA, the
Company would be unable to obtain FDA supplemental approval at the Brooklyn
plant for a new supplier except in very limited circumstances.
 
    The DEA limits the quantity of the Company's inventories of certain raw
materials used in the production of controlled substances based on historical
sales data. These limitations could increase the likelihood of raw material
shortages and of manufacturing delays in the event the Company was required to
find new suppliers of these raw materials.
 
    In 1994, one of the Company's suppliers, Penick and its parent, filed a
Chapter 11 petition under the United States Bankruptcy Code. Penick continues to
supply the Company but there can be no assurance it will continue to do so. See
"--Products and Product Developments--Acquisitions."
 
EMPLOYEES
 
    As of December 31, 1995, the Company had approximately 247 full-time
employees. Approximately 120 are administrative and professional personnel and
the balance are in production and shipping. Among the professional personnel,
eight are engaged in product development. Approximately 90 employees at the
Company's Brooklyn plant are represented by a local collective bargaining unit
whose agreement with the Company expires on July 1, 1997. Management believes
that its relations with its employees and unions are satisfactory.
 
PROPERTIES
 
    Halsey leases, as sole tenant, a total of approximately 112,300 square feet,
in three buildings on Pacific Street and Dean Street in Brooklyn, New York. Each
of these leases is between Halsey and unaffiliated lessors. The approximate
aggregate minimum rental commitments under these operating leases are as
follows: $884,000 for the year 1995, $928,000 for the year 1996 and $975,000 for
the year 1997. These leases expire on December 31, 2005. The buildings leased by
Halsey in Brooklyn house research and development and manufacturing facilities
and corporate offices.
 
    Houba owns approximately 45,000 square feet of building space on
approximately 30 acres of land in Culver, Indiana, which includes a modern
15,000 square foot manufacturing facility. This manufacturing complex houses
separate plants for the production of Doxycycline raw materials, Doxycycline
capsules and tablets and Biotin raw materials. In 1996, in conjunction with a
settlement with two former employees, the Company acquired real
property, improved by a residential property, in Culver, Indiana adjacent to the
manufacturing facility. The Company became the lessor of the residential
property upon closing of the acquisition.
 
    Cenci and Cenci Powder together own approximately 6,700 square feet of
manufacturing and distribution building space on approximately one-half acre of
land in Fresno, California. In early 1992, the Company acquired additional land
adjoining this property for the purpose of expanding the manufacturing
facilities and distribution space located on such property. In addition, Cenci
and Cenci Powder lease approximately 18,000 square feet of space in a building
located in Fresno, California used for manufacturing and corporate offices.
During the years ended December 31, 1995, 1994 and 1993, Cenci and Cenci Powders
paid an aggregate of $86,000, $99,000 and $91,000, respectively, to minority
shareholders in respect to this lease.
 
    The Company also leases office space in Westwood, New Jersey for its
marketing and sales departments on a year-to-year basis.

                               LEGAL PROCEEDINGS
 
GOVERNMENT CONSENT DECREES
 
    On June 21, 1993, the Company entered into a plea agreement with the DOJ to
resolve the DOJ's investigation into the manufacturing and recordkeeping
practices of the Company's Brooklyn plant. Under the terms of the plea
agreement, the Company agreed to plead guilty to five counts of adulteration of
drug products shipped in interstate commerce. Each count involved product
adulteration and recordkeeping deficiencies relating to a single drug product,
Quinidine Gluconate (324mg tablets), manufactured at the Brooklyn plant. The
plea agreement also requires the Company to pay a fine of $2,500,000 over five
years in quarterly installments of $125,000, commencing on or about September
15, 1993. The Company's plea was entered in and the terms of the plea agreement
approved by the United States District Court for the District of Maryland on
July 16, 1993. Two installments have been paid to date. Only additional partial
payments have been paid in the amount of $90,000. The agreement with the DOJ
stipulates that if any payments are not made in a timely fashion the entire
amount of the fine shall become due and payable immediately. As a result, the
entire amount of the settlement has been classified as current. Such nonpayment
also constituted a default under the Company's Credit Agreement with its banks.
As of the date of this Prospectus, no action has been initiated to require 
payment of the entire outstanding amount of the fine.
 
    On June 29, 1993, the Company entered into a consent decree with the U.S.
Attorney for the Eastern District of New York on behalf of the FDA that resulted
from the FDA's investigation into the Brooklyn plant's compliance with the FDA's
CGMP regulations. Under the terms of the consent decree, the Company is enjoined
from shipping any solid dosage drug products (i.e., excluding liquid drug
formulations) manufactured at the Brooklyn plant until the Company establishes
to the satisfaction of the FDA that the methods used in, and the facilities and
controls to be used for manufacturing, processing, packing, labeling and holding
any drug, are established, operated, and administered in conformity with the
Federal Food, Drug, and Cosmetic Act and all CGMP regulations. As part of
satisfying the foregoing requirements, the Company will be required to validate
the manufacturing processes for each solid dosage drug product prior to
manufacturing and shipping the drug product. The Company, however, is permitted
under the terms of the consent decree to manufacture and ship from the Brooklyn
plant certain identified drug products at its own risk provided that: (i) at
least twice each month, the Company's independent expert certifies that each
batch of drug products upon validation will have been manufactured in accordance
with the CGMP Regulations and the formulation described in the drug products
approved NDA or ANDA, until such time as validation is completed for these
products; and (ii) for any batches of these products that have already been
manufactured, such certification will include certification by a Company
representative with personal knowledge of the records relating to such drug that
such records are accurate and complete and a certification signed by an
independent expert that he has personally reviewed the records provided and that
in his professional opinion the foregoing requirement concerning validation has
been met. The Company commenced shipments of five of the six solid dosage
products under the foregoing certification process. One of such five products
has since been sold to Mallinckrodt, on whose behalf the Company continues to
manufacture the product.
 
SHAREHOLDER AND DERIVATIVE ACTIONS
 
    On March 31, 1993, and April 1, 1993, five class-action lawsuits were filed
in Federal Court by shareholders against the Company and certain of its then
directors. Each of the actions alleged that the Company and its directors had
made misleading statements and omissions relating to the prospects of the
Company's business and products, including products under development, as well
as relating to the status of DOJ and FDA investigations. On May 20, 1993 and
October 14, 1993, two separate shareholders derivative lawsuits were filed in
New York State Court against the Company and certain of its directors. Each of
these lawsuits alleged that the Company and its directors concealed certain
 
                                       33
<PAGE>
government investigations by the FDA and the DOJ. These actions also alleged
that the directors breached their fiduciary duty in connection with the
dispositions by them of shares of Common Stock on the basis of material
information which was not publicly known. In June 1994, the Company agreed to a
settlement of these lawsuits. In November 1994, both the Federal and State
Courts approved the terms of the settlement, under which the Company agreed to
pay $1,000,000 in cash and, at the Company's option, either (i) to issue shares
of Common Stock having an aggregate market value, as of the date of
distribution, of $3,000,000, or (ii) to pay $3,000,000 in cash, or (iii) to
distribute any combination of shares or cash having a combined value as of the
date of distribution of $3,000,000. The initial payment of $1,000,000 was paid
by the Company's insurers. In November 1995 the Company satisfied the remainder
of its settlement obligations by issuing to approved class members a total of
824,742 shares of Common Stock at a per share price of $3.6375, or an aggregate
value of $3,000,000.
 
OTHER GOVERNMENTAL PROCEEDINGS
 
    The Company received a federal grand jury subpoena in 1993 from the U.S.
District Court for the Eastern District of Pennsylvania for documents in
connection with an investigation of price fixing and bid rigging on government
contracts for Prednisone. The Company, which has not been identified as a target
of the investigation, has responded to the subpoena by making certain documents
available to the Government and, at this time, has received no further request
from the Government.
 
    By letter dated November 12, 1993, the Staff of the Commission requested
that the Company provide to the Commission, on a voluntary basis, information
and documents regarding the ingredients and filings relating to the following
drugs: quinidine gluconate, propylthiourical, acetaminophen and codeine
phosphate, metronidazole, quinidine sulfate, and hydralazine hydrochloride. The
Staff advised the Company that the inquiry relates to public information
disseminated by the Company and trading in the Company's securities during the
period August 1987 through July 1993. The Company is cooperating with the Staff
and has made available various documents. These documents relate to the testing,
formulations and sale of these drugs which were maintained by the Company at a
facility in Maryland. In April, 1994, the Staff requested additional
documentation regarding these matters. The Company has complied with the
additional request. On July 5, 1994, the Company made a formal submission to the
Staff and outlined the parameters of a proposed settlement. An additional
submission was made on January 31, 1995, to bring additional information to the
attention of the Staff. In May 1995, a formal Order of Investigation was issued
by the Commission covering the foregoing matters. In June 1995, additional
documents were submitted. Officers and directors of the Company have also
testified before the SEC. On October 24, 1995, the SEC staff informed the
Company that it would recommend that the Commission authorize the institution of
an administrative proceeding pursuant to Section 21C of the Exchange Act against
the Company. Specifically the staff indicated it would seek an Order after
filing a complaint requiring the Company to cease and desist from violating
Section 17(a) of the Securities Act and Sections 10(b) and 13(a) of the Exchange
Act and Rules 10b-5, 12b-20, 13a-1 and 13a-13 thereunder. The proposed action
would allege that the Company's December 31, 1990 and December 31, 1991 Annual
Reports on Form 10-K and March 31, 1991, June 30, 1991, September 30, 1991,
March 31, 1992, June 30, 1992, and September 30, 1992 quarterly reports on Form
10-Q were materially false and misleading. The SEC staff proposal conforms in
large part to the settlement proposal submitted by the Company. Under this
proposal, the Company, without admitting or denying the allegations, would then
enter into a Consent Decree not to violate the law in the future. The Company is
unable to predict the likelihood of the Commission adopting the staff proposal,
although the staff has indicated that it anticipates such action. An adverse
determination in this regard could have a material adverse effect on the
Company's financial condition.
 
    By letter dated October 23, 1995, the Company was notified by the New York
State Education Department that the Professional Conduct Officer of the Office
of Professional Discipline had determined that there was sufficient evidence of
professional misconduct on the Company's part to warrant a disciplinary
proceeding pursuant to New York law. Upon contacting the Deputy Director of the
Office of
 
                                       34
<PAGE>
Professional Discipline, counsel for the Company was advised that the alleged
misconduct related to the same activities that were the subject of the DOJ
investigation, indictment and plea. The Company submitted a written response on
November 16, 1995. As of the date of this Prospectus, the Company has not
received a response to its submission.
 
    On November 9, 1995, the Company received two Notices of Charge of
Discrimination from the United States Equal Employment Opportunity Commission
relating to two claimed violations of Title VII of the Civil Rights Act of 1964.
The first charge of employment discrimination was filed on October 31, 1995 by a
female employee of the Company and alleges sexual discrimination and harassment.
A second separate charge of discrimination was also filed on October 31, 1995,
by another female employee alleging sexual harassment against the same
individual. On November 20, 1995, the EEOC terminated its process with respect
to the charges and issued Notices of Right to Sue to the claimants. In February
1996 two lawsuits were filed in the Eastern District of New York captioned
Golovatskaya v. Halsey Drug Co., 96 CIV 0662 and Petrakova v. Halsey Drug Co.,
96 CIV 0660 in connection with the above charges. The lawsuits seek unspecified
damages. At this early stage of the proceedings, the Company is unable to
predict with reasonable certainty the likely outcome of these claims.
 
CENCI PROCEEDING
 
    The Company is a defendant in a lawsuit currently pending in the United
States District Court for the Eastern District of California entitled Cenci v.
Halsey Drug Co. The claims in this lawsuit relate to a 1991 Stock Purchase
Agreement whereby the Company agreed to purchase 51% of the stock of Cenci.
 
    The plaintiff, both individually and as a shareholder of Cenci and Cenci
Powder, has sued the Company, one of the current officers and two former
officers of the Company. The complaint alleges that the Company has breached a
number of representations made during the course of the negotiations leading to
the stock purchase, including the representation that the Company would provide
financial assistance to both Cenci and Cenci Powder. The Complaint also alleges
misrepresentations relating to the scope of FDA's investigation of the Company.
 
    The Complaint, which includes several causes of action, seeks unspecified
compensatory damages, as well as punitive damages, rescission, specific
performance, reformation and a declaration as to what amount, if any, is owed to
plaintiff.
 
    The Company has retained California counsel to represent its interests.
Plaintiff filed its Fifth Amended Complaint, and the Company has filed its
Answer and Counterclaims in response to this latest amended complaint. The
parties are currently conducting document discovery. At this preliminary stage,
the Company is unable to determine the outcome of this litigation with any
reasonable certainty.
 
OTHER PENDING LEGAL PROCEEDINGS
 
    The Company was named as a defendant in an action commenced on August 19,
1995 by the Company's former product liability insurer ("Lexington") captioned
Lexington Insurance Company v. Halsey Drug Co., Inc., 95 Civ. 3403, pending in
the United States District Court for the Eastern District of New York. The
Complaint seeks the recovery of sums paid by Lexington to settle a lawsuit
brought by Linda K. Walton relating to the ingestion of quinidine gluconate
allegedly manufactured by the Company. The Complaint requests not less than
$75,000 in damages and payment by the Company of a $25,000 deductible, and a
declaration that the Walton claim, and other similar claims are not covered
under their policy. The Company and Lexington have agreed to a settlement
pursuant to which the Company is required to pay $25,000 with respect to the
Walton claim (not including an undisputed
 
                                       35
<PAGE>
$25,000 deductible which the Company is also required to pay) over a three month
period. Lexington will dismiss the declaratory portion of the Complaint without
prejudice.
 
    The Company was named as a defendant in an action captioned Union Mutual
Fund and Vacation Fringe Benefit Fund v. Halsey Drug Company, Inc., 95 Civ. 955,
pending in the United States District Court for the Eastern District of New
York. The Complaint seeks sums allegedly owed to two of the Company's labor
union funds under the Company's collective bargaining agreement. Plaintiffs seek
not less than $165,000.
 
    On or about August 8, 1995, the Company and the plaintiffs agreed to settle
the action. The settlement obligated the Company to pay the alleged arrears in
monthly installments. The Company has paid in full the settlement amount.
 
    The Company was named as a defendant in an action captioned Allied Welfare
Fund, Vacation Fringe Benefit Fund and Union Mutual Fund v. Halsey Drug Co., 96
Civ 3655, brought in the United States District Court for the Eastern District
of New York. The Complaint seeks sums allegedly owed to three of the Company's
labor union funds under the Company's collective bargaining agreement.
Plaintiffs seek approximately $272,000. On or about April 29, 1996, the Company
and the plaintiffs agreed to settle the action. The settlement obligates the
Company to remain current on its obligations and to pay portions of the alleged
arrears in installments.
 
    In March 1985, the Company was named as a defendant in an action instituted
in the Court of Common Pleas, Bucks County, Pennsylvania entitled Mellon v.
Barre National Drug Co., et al. This suit was brought by a father as
administrator of his deceased daughter's estate, individually and on behalf of
her children, against 29 drug companies including the Company. The deceased's
death allegedly resulted from her use of the drug Ipecac, an expectorant
distributed by the Company, which she used in connection with her bulimia. The
plaintiff was unable to determine which of the defendants actually produced the
Ipecac used by the decedent. The complaint contained 12 counts, nine of which
set forth different theories of liability each seeking in excess of $5 million
in damages. The remaining three counts included a count to recover damages in
excess of $5 million under the Pennsylvania Wrongful Death Act, a count to
recover damages in excess of $5 million under the Pennsylvania Survival Act and
a count to recover punitive damages in excess of $10 million. The Company's
insurance carrier assumed the defense of this action. On November 13, 1987, the
court dismissed seven of the nine counts of the complaint which set forth
theories of liability. The two counts regarding theories of liability which
remain are theories based on claims of negligence and strict product liability.
A motion for summary judgment on behalf of all defendants was granted by the
trial court. The decision was affirmed on appeal. Plaintiff sought permission to
appeal in the Pennsylvania Supreme Court, and the court denied plaintiff's
request.
 
    On March 4, 1992, an action was commenced against the Company and numerous
other pharmaceutical manufacturers in the Pennsylvania Court of Common Pleas,
Philadelphia Division, entitled captioned Ciavarelli and Ciavarelli v. Abbott
Laboratories, Inc., et al. The Complaint contains seven causes of action,
including negligence, strict liability and breach of warranty, among others, in
connection with the alleged exposure of Debra Ciavarelli in utero to
diethylstilbestrol ("DES"). The plaintiff was unable to determine which of the
defendants produced the DES used by Ms. Ciavarelli. The Complaint seeks in
excess of $25,000 in compensatory and punitive damages. This matter has been
referred to the Company's insurance carrier for defense, which has been assumed.
Twenty-two additional actions have been commenced and are still pending against
the Company along with numerous other pharmaceutical manufacturers in the
Pennsylvania Court of Common Pleas, Philadelphia Division, during 1992 and 1993.
Each of these actions alleges injury in connection with exposure to the drug
diethylstilbestrol (DES) and each seeks in excess of $25,000 in compensatory and
punitive damages. In each suit, the plaintiff was unable to determine which of
the defendants produced the DES that was used. Nineteen similar actions have
already been settled and dismissed.
 
                                       36
<PAGE>
    Two DES claims referred to the Company's insurance carriers are pending in
other jurisdictions.
 
    Each of the following matters have been referred to the Company's insurance
carrier for defense. The Company does not believe any of the actions will have a
material impact on the Company's financial condition.
 
    The Company has been named as a defendant in three additional actions which
have been referred to the Company's insurance carrier and have been accepted for
defense. The first action, Alonzo v. Halsey Drug Co., Inc. and K-Mart Corp., No.
64DOT-95111-CT-2736 (Indiana Superior Court, Porter County), was commenced on
November 7, 1995 and involves a claim for unspecified damages relating to the
alleged ingestion of "Doxycycline 100". The second action, Files v. Halsey Drug
Co., Index No. 198787/93 (New York Supreme Court, Suffolk County), commenced on
September 16, 1993, seeks $10,000,000 in damages for wrongful death allegedly
caused by the ingestion of Isoniazid. The action is currently in discovery. The
third action, Hunt v. Halsey Drug Co., Inc. Index No. 33723/93 (New York Supreme
Court, Kings County), was commenced on October 21, 1993, and seeks the recovery
of $8,000,000 for alleged personal injuries suffered by a Wells Fargo security
guard who had responded to a triggered alarm and was shot by a perpetrator. The
action is currently in discovery.

<PAGE>
Mr. Dubowy's resignation from the Board in November 1995, and Messrs. Ferran's
and Mr. Limongelli's resignations from the Compensation Committee in November
1995, Alan J. Smith and Richard H. Francis were appointed to the Compensation
Committee. The principal functions of the Compensation Committee are to consult
with and make recommendations to the Board of Directors about executive
compensation arrangements and the compensation of employees, including the grant
of options under the Company's 1995 Stock Option and Restricted Stock Plan to
individual officers and key employees. The Compensation Committee met once in
1995.

Nominating Committee which was composed of Alexander Marcus and Rosendo Ferran.
This Committee did not meet during 1995. Mr. Marcus resigned from the Board in
April 1996 and has not been replaced on the Nominating Committee. The principal
functions of the Nominating Committee are to establish criteria for procedures
of the election for directors and others, review the qualifications of and, in
appropriate cases, interview candidates proposed for nomination, and perform
such other duties in connection with the election or termination of directors
and officers as the Board of Directors may request.
 
    Audit Committee. On April 30, 1993, the Board established an Audit Committee
composed of Joseph F. Limongelli, Jerome Dubowy and Rosendo Ferran. Following
Mr. Dubowy's resignation from the Board and Mr. Limongelli's and Mr. Ferran's
resignations from the Audit Committee in November 1995, Alan J. Smith and
Richard H. Francis were appointed to the Audit Committee. The Audit Committee is
responsible for nominating the Company's independent auditors, working with the
independent auditors and the internal auditing staff of the Company and other
corporate officials, reviewing the financial statements of the Company and
reporting on the results of the audits to the Board, and submitting to the Board
its recommendations relating to the Company's financial reporting, accounting
practices and policies, and financial accounting and operation controls. The
Audit Committee did not meet during 1995.
 
INFORMATION WITH RESPECT TO COMPENSATION COMMITTEE INTERLOCKS AND INSIDER
PARTICIPATION
 
    Rosendo Ferran, who was a member of the Compensation Committee until
November 1995, is President and Chief Executive Officer of the Company.
 
COMPENSATION OF DIRECTORS WHO ARE NOT EMPLOYEES OR OFFICERS
 
    Directors who are not officers or employees of the Company are compensated
by payment of an annual retainer of $25,000 and an additional fee of $500 per
meeting attended, and are reimbursed for travel and other expenses incurred in
connection with their services to the Company.
 
    In September 1993, the Company entered into an Independent Consulting
Agreement with Joseph F. Limongelli pursuant to which Mr. Limongelli provides
financial and business advisory services, including, without limitation, with
respect to proposed transactions considered by the Company from time to time.
The Company has agreed to pay Mr. Limongelli a consulting fee of $50,000 per
year, payable in equal monthly installments, to issue to Mr. Limongelli stock
options each year to acquire at least 10,000 shares of the Company's Common
Stock and to reimburse him for expenses incurred in connection with his
consulting services. The Consulting Agreement is for a term ending September 1,
1997, provided that either party may terminate the Agreement on 60 days' notice.
The compensation paid to Mr. Limongelli is subject to periodic review as to the
reasonableness of the fee by the Compensation Committee and is in addition to
his compensation as a director. In the event the Company terminates the
Agreement, the Company has agreed to pay Mr. Limongelli the consulting fee for
an additional 12 months following termination. If the Company terminates the
Consulting Agreement within six months after a change in control, as defined,
the Company has agreed to pay Mr. Limongelli the consulting fee for the period
from the date of termination through September 1,

OTHER COMPENSATORY ARRANGEMENTS
 
    Benefits. Executive officers and key employees participate in medical and
disability insurance plans provided to all non-union employees of the Company.
During 1995, the Company maintained term life insurance policies on behalf of
Rosendo Ferran and Leonard H. Weiss, the benefits of which are payable to
beneficiaries designated by these individuals. Aggregate premiums paid by the
Company during 1995 on all such policies amounted to $21,159. The value of these
payments to the individual officers are reflected where applicable in the
summary compensation chart. The Company also provided automobiles to certain of
its executive officers. Although the Company is unable to assign any value to
possible personal benefits derived for use of the automobiles, the Company
believes that, as to each officer, such personal benefits amount to less than
the lesser of $50,000 or 10% of such officer's compensation reported above in
the summary compensation table and, with respect to all executive officers as a
group, amount to less than $90,000.
 
STOCK OPTION GRANTS
 
    The Company maintains a stock option plan, as set forth below, but the
Company does not have any plan pursuant to which stock appreciation rights may
be granted.
 
    1984 Stock Option Plan. In March 1984, the shareholders of the Company
approved the adoption of a stock option plan (the "1984 Stock Option Plan"). The
1984 Stock Option Plan, as amended provided for the grant of options to purchase
up to 1,000,000 shares. The 1984 Stock Option Plan terminated in March 1994.
 
                                       40
<PAGE>
    Incentive stock options ("ISO's") to purchase 821,666 shares and
non-qualified options to purchase 120,363 shares had been granted under the 1984
Stock Option Plan. The average per share exercise price for all such outstanding
ISO's, of which there are approximately 138,900, is approximately $3.58 and the
per share price of the Company's Common Stock on the grant dates ranged from
$2.50 to $6.25 per share. No exercise price of an ISO was set less than 110% of
the fair market value of the underlying Common Stock on the date of grant to any
person who owns stock possessing more than 10% of the total voting power of the
Company and no exercise price of an ISO was set less than 100% of the fair
market value of the underlying Common Stock on the date of grant to any other
person. There are no other options outstanding under the 1984 Stock Option Plan.
 
    1995 Stock Option Plan. In September 1995 the Company established the 1995
Halsey Drug Co., Inc. Stock Option and Restricted Stock Purchase Plan (the "1995
Stock Option Plan"). Under the Plan, the Company may grant options to purchase
up to 1,000,000 shares. Incentive stock options may be granted to employees of
the Company and its subsidiaries, and non-qualified options may be granted to
employees, directors and other persons employed by, or performing services for,
the Company and its subsidiaries. Subject to the Plan, the Compensation
Committee determines the employees to whom grants are made and the vesting,
timing, amounts and other terms of such grants. An employee may not receive
incentive stock options exercisable in one calendar year for shares with a fair
market value on the date of grant in excess of $100,000. No quantity limitations
apply to the grant of non-qualified stock options.
 
    As of December 31, 1995, ISO's to purchase 461,600 shares had been granted
under the 1995 Stock Option Plan. The average per share exercise price for all
outstanding ISO's under the 1995 Stock Option Plan is approximately $3.19 and
the average per share exercise price of the Company's Common Stock on the grant
dates ranged from $3.00 to $3.44 per share. No exercise price of an ISO was set
less than 110% of the fair market value of the underlying Common Stock on the
date of grant to any person who owns stock possessing more than 10% of the total
voting power of the Company and no exercise price of an ISO was set less than
100% of the fair market value of the underlying Common Stock on the date of
grant to any other person. There are no other options outstanding under the 1995
Stock Option Plan.
 
    The following table sets forth selected option grant information for the
fiscal year ended December 31, 1995 awarded to the Chief Executive Officer and
each of the executive officers of the Company whose compensation exceeded
$100,000.

    Employees of the Company who are at least 20 1/2 years of age and have
completed at least one year of service are eligible to participate in the
Pension Plan. This defined benefits pension plan provides monthly benefits at a
participant's normal retirement date (the participant's 65th birthday) equal to
9% of the participants' compensation. In order to qualify for a full pension
under this formula, the participant must have 18 years of service; the benefit
under the formula is reduced pro-rata for each year of service at the normal
retirement date less than 18. For purposes of determining the benefit at a
 
                                       42

lump sum equal to three times his base annual salary at the highest rate in
effect during the 12 months immediately preceding his date of termination and
all stock options then held by Mr. Ferran shall automatically become vested.
 
    The employment agreement of Mr. Ferran also obligates the Company to use its
best efforts to cause Mr. Ferran to be nominated as a director at each annual

ADVANCES
 
    From time to time the Company has made advances against anticipated bonuses
to Rosendo Ferran, the President, Chief Executive Officer and a director of the
Company. These advances, which do not bear interest, aggregated $48,500 at
December 31, 1992. In April 1993, the Company made an additional advance to Mr.
Ferran in the amount of $62,500. Mr. Ferran commenced repaying the advances by
means of payroll deductions beginning in April 1993. As a result of such
repayments, the amount outstanding under the advances aggregated $54,900 at
December 31, 1995.
 
                              CERTAIN TRANSACTIONS
 
    On October 27, 1994, the Company signed a Letter of Intent ("LOI") with RPI,
a wholly owned United States subsidiary of Ranbaxy Laboratories Ltd. of New
Delhi, India. The Company received $1,000,000 from RPI in payment for 500,000
shares of Common Stock in accordance with the terms of the LOI. The LOI provided
for completion of due diligence by RPI within a period of 30 days, after which
the parties would negotiate and finalize a definitive agreement. After execution
of a definitive agreement, RPI was to have purchased an additional 500,000 newly
issued shares of Common Stock for $1,000,000. On November 29, 1994, the Company
announced that RPI had decided not to proceed with its second purchase of the
Company's Common Stock. Pursuant to the LOI, RPI had the right to have the RPI
Shares registered under the Securities Act. In August 1995, the Company
repurchased the RPI Shares for an aggregate purchase price of $1,100,000, which
funds were derived from the proceeds of the July Private Offering. See "The
Private Offerings."
 
    In connection with the November Private Placement, the Company agreed to use
its best efforts to appoint two independent directors to its Board of Directors,
each of whom are reasonably acceptable to the holders of a majority in interest
(the "Majority in Interest") of the principal amount of the November Debentures.
The Board of Directors has agreed to nominate and appoint, subject to
shareholder approval, such individuals to the Board for so long as the
Debentures remain outstanding. In this regard, Seymour Marcus and Dr. Jerome
Dubowy resigned from the Board of Directors effective November 28, 1995, and
Richard H. Francis was appointed by the Board to serve as a director until the
1996 annual meeting of shareholders and until his successor is duly elected and
qualified. In addition to Mr. Francis, the Majority in Interest have requested
that William G. Skelly be nominated to serve as a director.
 
    The Company has agreed to use its best efforts to appoint a Chief Financial
Officer reasonably acceptable to the Majority in Interest. For so long as the
Debentures remain outstanding, any successor Chief Financial Officer similarly
must be reasonably acceptable to the Majority in Interest. As of the date
hereof, the Company has not appointed a Chief Financial Officer.
 
    Rosendo Ferran, the Chief Executive Officer and a director of the Company,
Richard H. Francis, a director of the Company, and Alan J. Smith, a director of
the Company, purchased two, five, and one November Units, respectively, in the
November Private Placement on the same terms as all other investors in the
November Private Placement.
 
    HKS assisted the Company in the July and November Private Placements. For
its services, the Company paid HKS a fee equal to 5% of the gross proceeds of
the Private Placements, and reimbursed HKS for its out-of-pocket expenses. In
addition, HKS may receive a fee upon the exercise of each July and November
Warrant.
 
    In 1996, the Company agreed to issue 25,397 shares to Kahn Consultants,
Inc., financial consultants, in lieu of $100,000 in compensation. The Company
expects to issue the shares prior to the effectiveness of the Registration
Statement of which this Prospectus is a part.

    In addition, all shares of Common Stock offered hereby (including the
Underlying Shares, upon the issuance thereof) are being offered directly by the
Selling Securityholders. The Company will not receive any of the proceeds from
the sale of shares by the Selling Securityholders. The Selling Securityholders
may sell such shares from time to time, provided a current registration
statement with respect to such securities is then in effect. The distribution of
shares of Common Stock offered hereby by

take place on the Exchange, including ordinary broker's transactions, privately
negotiated transactions or through sales to one or more dealers for resale of
such securities as principals, at market prices prevailing at the time of sale,
at prices related to such prevailing market prices or at negotiated prices.
Selling Securityholders may also pledge their shares to banks, brokers or other
financial institutions as security for margin loans or other financial
accommodations that may be extended to such Selling Securityholders, and any
such pledgee institution may similarly offer, sell and effect transactions in
such shares. Usual and customary or specifically negotiated brokerage fees or
commissions may be paid by the Selling Securityholders (or their pledgees).
 
    In order to comply with the securities laws of certain states, the shares of
Common Stock offered hereby may not be sold unless they have been registered or
qualified for sale in the applicable state or an exemption from the registration
or qualification requirement is available and is complied with by the Company
and the Selling Securityholders.
 
    The Selling Securityholders and intermediaries through whom the shares
offered hereby are sold may be deemed to be "underwriters" within the meaning of
the Securities Act with respect to such securities.
 
    Pursuant to applicable rules and regulations under the Exchange Act, any
person engaged in a distribution of securities may not simultaneously engage in
market-making activities with respect to the securities for a period of two
business days prior to the commencement of such distribution. In addition, and
without limiting the foregoing, each Selling Securityholder will be subject to
applicable provisions of the Exchange Act and the rules and regulations
thereunder, including without limitation, Rules 10b-6, 10b-6A and 10b-7, which
provisions may limit the timing of the purchases and sales of securities of the
Company by the Selling Securityholders.
 
    The Company has agreed to pay all fees and expenses incident to the
registration of the Common Stock offered hereby, except fees and expenses of
counsel or other professionals or advisors, if any, to the Selling
Securityholders.
 
    The Company has agreed to pay HKS a fee in connection with the exercise of
each Redeemable Warrant.

Board of Directors
 Halsey Drug Co., Inc.
 
 We have audited the accompanying consolidated balance sheets of Halsey Drug
Co., Inc. and Subsidiaries as of December 31, 1995 and 1994, and the related
consolidated statements of operations, stockholders' equity and cash flows for
each of the three years in the period ended December 31, 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, the financial statements referred to above present fairly, in
all material respects, the consolidated financial position of Halsey Drug Co.,
Inc. and Subsidiaries as of December 31, 1995 and 1994, and the consolidated
results of their operations and their consolidated cash flows for each of the
three years in the period ended December 31, 1995, in conformity with generally
accepted accounting principles.
 
 As more fully discussed in Note A, the accompanying financial statements have
been prepared assuming that the Company will continue as a going concern. The
Company has incurred a loss of approximately $2,203,000 during the year ended
December 31, 1995 and as of that date has a deficiency in working capital of
approximately $7,393,000. In addition, the Company's current banking agreement
expires on March 31, 1996 and the Company is currently not in compliance with
the financial covenants of its banking agreement and its convertible
subordinated debentures agreements. These matters raise substantial doubt about
the Company's ability to continue as a going concern. Management's plans in
regard to these conditions are described in Note A. The financial statements do
not include any adjustments that may result from the outcome of this
uncertainty.

                 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------
                        December 31, 1995, 1994 and 1993
 
NOTE A - SUMMARY OF ACCOUNTING POLICIES
 
  A summary of the significant accounting policies consistently applied in the
preparation of the accompanying consolidated financial statements follows.
 
1. Principles of Consolidation and Basis of Presentation
 
  The consolidated financial statements include 100% of the accounts of the
Company and its wholly-owned subsidiaries, Blue Cross Products Co., Inc., Houba,
Inc., Halsey Pharmaceuticals, Inc., and Indiana Fine Chemicals Corporation, The
Medi-Gum Corporation, its 51%-owned subsidiaries, H.R. Cenci Laboratories, Inc.
and Cenci Powder Products, Inc. The Medi-Gum Corporation and Halsey
Pharmaceuticals have not commenced operations. All material intercompany
accounts and transactions have been eliminated.
 
  As of December 31, 1995, the Company has a working capital deficiency of
approximately $7,393,000, has an accumulated deficit of approximately
$13,089,000, has incurred a loss of approximately $2,203,000 during the year
ended December 31, 1995, and is not in compliance with its financial covenants
pursuant to its banking agreement and its convertible subordinated debenture
agreements. In addition the Company's credit agreement with its banks expires
March 31, 1996. These factors and the Food and Drug Administration ("FDA") and
other matters as discussed in Note M, raise substantial doubt about the
Company's ability to continue as a going concern. The financial statements do
not include any adjustments relative to the recoverability and classification of
recorded asset amounts or amounts and classification of liabilities that might
be necessary should the Company be unable to continue in existence. Management's
plans with respect to those conditions include seeking alternative sources of
financing. In this regard, the Company (a) is reviewing several unsolicited
expressions of interest from prospective joint venture partners and investors,
(b) plans to refinance or extend the maturity date of the Company's bank debt,
and (c) has sold the rights to one of its products to a major vendor and has
received a commitment for future production of such product (Note I). There can
be no assurance that management can obtain alternative sources of financing.
 
2. Inventories
 
  Inventories are stated at the lower of cost or market; cost is determined
using the first-in, first-out method.
 
3. Property, Plant and Equipment
 
  Property, plant and equipment are stated at cost less accumulated depreciation
and amortization. Depreciation and amortization are provided for in amounts
sufficient to relate the cost of depreciable assets to operations over their
estimated service lives, principally on a straight-line basis. The estimated
lives used in determining depreciation and amortization are:
 

Buildings                  25 years
Machinery and equipment    5-10 years
Leasehold improvements     5-10 years

 
  Leasehold improvements are amortized over the lives of the respective leases
or the service lives of the improvements, whichever is shorter.
 
4. Income Taxes
 
  The Company adopted Statement of Financial Accounting Standards No. 109,
"Accounting for Income Taxes" ("SFAS No. 109"), as of January 1, 1993. The
standards for SFAS No. 109 require that the Company utilize an asset and
liability approach for financial accounting and reporting for income taxes. The
primary objectives of accounting for income taxes under SFAS No. 109 are to (a)
recognize the amount of tax payable for the current year and (b) recognize the
amount of deferred tax liability or asset based on management's assessment of
the tax consequences of events that have been reflected in the Company's
financial statements or tax returns. The cumulative effect of this change was to
increase the 1993 net loss by $267,000.
 
5. Loss Per Share
 
  The computation of loss per share of Common Stock is based upon the weighted
average number of common shares outstanding during the period plus (in periods
in which they have a dilutive effect) the effect of common shares contingently
issuable upon exercise of stock options and warrants. Fully diluted earnings per
share is considered equal to primary earnings per share for all years presented
as the effect of other potentially dilutive securities would be antidilutive.

                        December 31, 1995, 1994 and 1993
 
6. Statement of Cash Flows
 
  For purposes of the statements of cash flows, the Company considers all highly
liquid debt instruments purchased with an original maturity of three months or
less to be cash equivalents. The Company paid income taxes for the years ended
December 31, 1995, 1994 and 1993 of $201,000, $39,000 and $199,000,
respectively, and interest of $786,000, $504,000 and $406,000, respectively.
 
7. Costs in Excess of Net Assets Acquired
 
  The Company amortizes its costs in excess of net assets acquired on a
straight-line basis over a five-year period. Amounts paid in excess of net
assets acquired of $1,127,000, net of accumulated amortization of $932,000 and
$707,000 in 1995 and 1994, respectively, are included in other assets in the
accompanying consolidated financial statements. On an ongoing basis, management
reviews the valuation and amortization of goodwill to determine possible
impairment by comparing the carrying value to the undiscounted cash flows of the
related assets.
 
8. Use of Estimates in Consolidated Financial Statements
 
  In preparing consolidated financial statements in conformity with generally
accepted accounting principles, management makes estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the consolidated financial
statements, as well as the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
9. Reclassifications
 
  Certain reclassifications have been made to the 1994 and 1993 presentation to
conform to the 1995 presentation.
 
10. Accounting Pronouncements Not Yet Adopted
 
  Adoption of Statement of Financial Accounting Standards No. 121 ("SFAS No.
121"), "Accounting for the Impairment of Long-Lived Assets and for Long-Lived
Assets to Be Disposed Of," is required for fiscal years beginning after December
15, 1995. The standards for SFAS No. 121 require that the Company recognize and
measure impairment losses of long-lived assets and certain identifiable
intangibles and value long-lived assets to be disposed of. The primary
objectives under SFAS No. 121 are to: (a) recognize an impairment loss of an
asset whenever events or changes in circumstances indicate that its carrying
amount may not be recoverable and (b) if planning to dispose of long-lived
assets or certain identifiable intangibles, such assets have been reflected in
the Company's consolidated balance sheet at the net asset value less cost to
sell. At December 31, 1995, the Company has not adopted SFAS No. 121. The impact
of adopting SFAS No. 121 on the Company's financial statements has not yet been
determined.
 
  Adoption of Statement of Financial Accounting Standards No. 123 ("SFAS No.
123"), "Accounting for Stock-Based Compensation," is required for fiscal years
beginning after December 15, 1995 and allows for a choice of the method of
accounting used for stock-based compensation. Entities may use the "intrinsic
value" method currently based on APB No. 25 or the new "fair value" method
contained in SFAS No. 123. The Company intends to implement SFAS No. 123 in
fiscal 1996 by continuing to account for stock-based compensation under APB No.
25. As required by SFAS No. 123, the pro forma effects on net income and
earnings per share will be determined as if the fair value-based method had been
applied and disclosed in the notes to the consolidated financial statements.
 
NOTE B - FAIR VALUE OF FINANCIAL INSTRUMENTS
 
  Statement of Financial Accounting Standards No. 107 ("SFAS No. 107"), "Fair
Value of Financial Instruments," requires disclosure of the estimated fair value
of an entity's financial instrument assets and liabilities. For the Company,
financial instruments consist principally of cash and cash equivalents,
long-term receivables, subordinated promissory notes and long-term debt.
 
  The following methods and assumptions are used to estimate the fair value of
each class of financial instrument for which it is practicable to estimate that
value:
 
1. Cash and Cash Equivalents
 
  The carrying amount reasonably approximates fair value because of the short
maturity of those instruments.
 
2. Long-Term Receivables
 
  The fair value of the Company's long-term receivables cannot be determined
based upon the uncertainty of the date on which the Company will collect such
receivable in accordance with its terms.

3. Long-term Debt and Convertible Subordinated Debentures
 
  The fair value of the Company's long-term debt and convertible subordinated
debentures is estimated based upon the quoted market prices for the same or
similar issues or on the current rates offered to the Company for debt of the
same remaining maturities.
 
  The carrying amount and fair value of the above financial instruments are as
follows:

NOTE E - DEBT
 
a. Line of Credit
 
  In December 1992, the Company entered into a credit agreement providing for
borrowings of up to $7,000,000 at the prime rate plus an initial margin of 1/2%,
originally maturing in December 1994. Upon certain conditions, as defined in the
agreement, the margin rate increases by 2%. Borrowings under the line were
available for working capital purposes based upon a percentage of the parent
company's eligible accounts receivable and are collateralized by such accounts
receivable. The agreement contains certain financial covenants, including
minimum interest

                        December 31, 1995, 1994 and 1993

coverage and working capital ratios, tangible net worth, limitations on capital
expenditures, and maximum debt-to-equity ratios. As of December 31, 1995, the
Company was not in compliance with the above covenants.
 
  In 1994, the Company and its banks amended the credit agreement to include the
stock of certain subsidiaries, the accounts receivable of Houba, Inc., and the
parent company's inventory and equipment as additional collateral, to increase
the initial margin rate to 2% (10.5% at December 31, 1995), to restrict certain
payments made by the Company, to require payment to be made by the Company to
the banks of any income tax refunds received by the Company, to extend the
maturity date to August 31, 1995, and to agree in principal to modify the
financial covenants at a later date. In addition, if the outstanding borrowings
were not repaid by August 30, 1995, the Company was required to pay $102,000,
which represented 3% of the then outstanding principal due to the banks. Such
amount was accrued in 1995 and fully paid in 1996.
 
  As consideration for the above amendments and the Company's continued
borrowings in excess of the borrowing formula, the Company has issued to the
banks stock warrants, expiring December 31, 1999, to purchase up to 635,653
shares of the Company's common stock at exercise prices ranging from $2.25 to
$2.375 per share (subject to the antidilution provisions of the credit
agreement, as amended). The fair value of the warrants, $200,000, as determined
by the Company's Board of Directors, was recorded by the Company in 1994 as
additional paid-in capital and a discount to bank debt which was fully amortized
through the maturity date, August 31, 1995.
 
  In addition, the Company and its banks amended the credit agreement as a
result of the Company having consummated private offerings of its securities on
July 18, 1995 and November 29, 1995. As consideration for waiving any breach or
default under the credit agreement as a result of these private offerings, the
Banks received $950,000 of the proceeds as payment for interest, fees and
principal and an extension of the warrant exercise period to July 17, 2000. In
addition, the exercise prices of all warrants for 635,653 shares of the
Company's common stock have been adjusted for antidilution to prices ranging
from $2.13 to $2.275.
 
b. Convertible Subordinated Promissory Note
 
  Pursuant to the Zatpack, Inc. ("Zatpack") agreement (Note N), the Company
issued a convertible subordinated promissory note dated December 1, 1994, to
Zatpack, for the cancellation of trade payables and advances by Zuellig Group
N.A., Inc. ("Zuellig") to the Company's subsidiaries, in the amount of
$1,292,000, bearing interest at 8% per annum, compounded annually, due December
1, 1997. The outstanding principal, plus all accrued and unpaid interest,
$1,395,000 at December 31, 1995, can be converted, at the option of Zatpack,
into the Company's common stock at the rate of one share of common stock for
every $2.50 of principal and interest being converted (the $2.50 is subject to
the antidilution provisions of the promissory note). The note is subordinated to
the bank debt.
 
c. Subordinated Promissory Notes
 
  On March 21, 1995 (see Note I), the Company satisfied certain accounts payable
by issuing a subordinated promissory note to Mallinckrodt Chemical Acquisition,
Inc. ("Mallinckrodt") for $1,200,000, bearing interest at 8% per annum, with
interest and principal payable at the earlier of: (i) receipt by Mallinckrodt of
all necessary authorizations from the FDA or (ii) September 21, 1997. The note
is collateralized by substantially all of the assets of the Company and is
subordinated to future bank indebtedness of up to $8,000,000. The $1,200,000
note represents the deferral of payment by the Company of a portion of its trade
accounts payable due to an affiliate of Mallinckrodt.
 
  On July 14, 1995, the Company borrowed from and issued a $200,000 subordinated
promissory note to Mallinckrodt, bearing interest at 8% per annum, with
principal and interest payable June 30, 1996. The principal and interest is
payable, at the option of Mallinckrodt, in the form of cash or a credit to the
Company's accounts receivable due from Mallinckrodt on June 30, 1996.

NOTE F - CONVERTIBLE SUBORDINATED DEBENTURES
 
  On July 18, 1995, the Company issued 408 units, at $10,000 per unit, in a
private placement of its securities ("July Private Placement"). Each unit
consists of: (i) a 10% convertible subordinated debenture due July 18, 2000 in
the principal amount of $10,000, interest payable quarterly, and convertible
into shares of the Company's common stock at a conversion price of $2.00 per
share, subject to dilution, and (ii) 750 redeemable common stock purchase
warrants ("warrants"). Each warrant entitles the holder to purchase one share of
common stock for $2.00, subject to adjustment during the five-year period
commencing July 18, 1995. The warrants are redeemable by the Company at a price
of $.01 per warrant at any time commencing July 18, 1996, provided that at July
18, 1996, the fair market value of the Company's common stock equals or exceeds
$2.00 per share for the 20 consecutive trading days ending on the third day
prior to the notice of redemption to the holders of the warrants.
 
  On November 29, 1995, the Company issued 366 units, at $10,000 per unit, in a
private placement of its securities ("November Private Placement"). Each unit
consists of (i) a 10% convertible subordinated debenture due November 29, 2000
in the principal amount of $10,000, interest payable quarterly, and convertible
into shares of the common stock at a conversion price of $2.50 per share,
subject to dilution, and (ii) 600 redeemable common stock purchase warrants. The
terms and conditions of the warrants issued in connection with the November
Private Placement are similar to those issued in the July Private Placement,
except that the exercise price of the warrants issued in the November Private
Placement is $2.50 per share.
 
  The Company received net proceeds from the July and November Private
Placements of $7,013,000, net of issuance costs of $727,000, and allocated the
market value of the warrants, as determined by the Company's Board of Directors,
$416,000, to additional paid-in capital with a corresponding adjustment to debt
discount. The net proceeds from such issuances have been or will be used for the
following purposes: repurchase of 500,000 shares of the Company's common stock,
registration of the underlying shares pursuant to the Private Placements, the
purchase of equipment, research and development costs and for working capital.
In addition, the Company was required to use $950,000 of the net proceeds to
repay a portion of its bank debt. At December 31, 1995, the Company was in
default of its convertible subordinated debentures agreements as a result of its
default with its banking agreement, and accordingly, the convertible
subordinated debentures are currently due.

  The Company has net operating loss carryforwards aggregating approximately
$6,613,000, expiring during the years 2009 through 2010. In addition, certain of
the Company's subsidiaries file separate Federal income tax returns and have
separate net operating loss carryforwards aggregating approximately $4,783,000,
expiring during the years 1998 through 2010.
 
  The Company's tax loss carryforwards could be limited by Section 382 of the
Internal Revenue Code with respect to the amount utilizable each year. This
limitation would reduce the Company's ability to utilize net operating loss
carryforwards included above. The amount of the limitation has not been
quantified by the Company.

  SFAS No. 109, requires a valuation allowance against deferred tax assets if,
based on the weight of available evidence, it is more likely than not that some
or all of the deferred tax assets may not be realized. The valuation allowance
at December 31, 1995 primarily pertains to uncertainties with respect to future
utilization of net operating loss carryforwards.
 
NOTE I - SALE OF ASSETS
 
  (a) On March 21, 1995, the Company sold its Abbreviated New Drug Application
("ANDA") for 5mg Oxycodone HCL/325mg Acetaminophen Tablets ("Tablets") and
certain equipment used in the production of the Tablets for up to $5.4 million
to Mallinckrodt. The Company received $500,000 of the proceeds in July 1994,
which has been recorded as deferred income on the Company's 1994 consolidated
balance sheet. Mallinckrodt also paid the Company $2,000,000 on March 21, 1995
and the remainder will be payable as follows: (i) $1,000,000 upon the Company
receiving general clearance from the FDA for unrestricted operations at its
Brooklyn facility and written notice from the FDA that it is in compliance with
certain provisions of the consent degree dated June 29, 1993 (such $1,000,000
will be recorded by the Company when general clearance is obtained from the FDA)
and (ii) $1,900,000 at the earlier of (a) Mallinckrodt receiving certain
authorizations from the FDA or (b) September 21, 1997. Mallinckrodt also agreed
to defer $1,200,000 of the Company's trade debt due to an affiliate of
Mallinckrodt (Note E).
 
  In connection with the agreement, the Company agreed to manufacture Tablets
for Mallinckrodt for a period of three years and Mallinckrodt agreed to order a
minimum number of Tablets from the Company for two years ending March 21, 1997.
The Company and Mallinckrodt entered into a noncompetition agreement pursuant to
which the Company agreed not to compete with Mallinckrodt and its affiliates
with respect to the Tablets ANDA until March 21, 2000.
 
  In addition, the Company issued to Mallinckrodt an option to purchase the ANDA
for acetaminophen/oxycodone capsules at an exercise price equal to 3/4 of annual
net capsule revenue, as defined. Upon exercise of the option, the Company and
Mallinckrodt would enter into agreements pursuant to which the Company would (i)
manufacture acetaminophen/oxycodone capsules for Mallinckrodt for a period of
time and (ii) be prohibited from competing with Mallinckrodt and its affiliates
with respect to the production of such capsules.

NOTE J - PENSION EXPENSE
 
  The Company maintains the following two pension plans:
 
1. Management Pension Plan
 
  The Company maintains a defined benefit pension plan covering substantially
all nonunion employees.
 
  Historically, the Company's funding policy for the management pension plan
(the "Plan"), had been to contribute amounts equal to its liability as
determined under the Employee Retirement Income Security Act of 1974 ("ERISA").
Under this funding policy, contributions would be sufficient to maintain plan
assets in excess of the projected benefit obligation. As of December 31, 1995,
the Company has not funded its 1994 ERISA obligation of approximately $116,000
and the remaining balance of its 1993 and 1992 ERISA obligations of
approximately $191,000. Failure to timely fund these obligations may result in
the termination of the Plan and/or other monetary penalties. During 1993, the
Company (i) amended the Plan to reduce employee benefits, (ii) terminated
certain employees sooner than expected, and (iii) reduced the discount rate used
to determine the projected benefit obligations, all of which did not have a
material effect on the Company's 1993 consolidated results of operations.
 
  Planned Company contributions over the next several years are expected to
improve the funded status of the Plan. The Plan's assets are diversified in
stocks, bonds, mutual funds and short-term and other investments.
 
  Net pension cost for the Plan consists of the following:

  The assumptions used as of November 30, 1995 and 1994 in determining pension
expense and funded status shown above were as follows:

Long-term rate of return on assets              7.00       7.00
 
2. Employees' Pension Plan
 
  The Company contributed approximately $450,000, $462,000 and $515,000 in 1995,
1994 and 1993, respectively, to a multiemployer pension plan for employees
covered by collective bargaining agreements. This plan is not administered by
the Company and contributions are determined in accordance with provisions of
negotiated labor contracts. Information with respect to the Company's
proportionate share of the excess, if any, of the actuarially computed value of
vested benefits over the total of the pension plan's net assets is not available
from the plan's administrator.
 
  The Multiemployer Pension Plan Amendments Act of 1980 (the "Act")
significantly increased the pension responsibilities of participating employers.
Under the provision of the Act, if the plans terminate or the Company withdraws,
the Company could be subject to a "withdrawal liability."
 
NOTE K - STOCK OPTION PLAN
 
  In September 1995, the stockholders of the Company approved the adoption of a
stock option and restricted stock purchase plan (the "1995 Option Plan"). The
1995 Option Plan replaces the Company's existing stock option plan which expired
in January 1994. The 1995 Option Plan provides for the granting of (i)
nonqualified options to purchase the Company's common stock at not less than the
fair market value on the date of the option grant, (ii) incentive stock options
to purchase the Company's common stock at not less than the fair market value on
the date of the option grant and (iii) rights to purchase the Company's common
stock on a "Restricted Stock" basis, as defined, at not less than the fair
market value on the date the right is granted. The total number of shares which
may be sold pursuant to options and rights granted under the 1995 Option Plan is
1,000,000. No option can be granted under the 1995 Option Plan after May, 2005
and no option can be outstanding for more than ten years after its grant.

NOTE L - COMMITMENTS
 
  The Company occupies plant and office facilities under noncancellable
operating leases which expired in December 1995. On October 31, 1994, the
Company entered into a new operating lease for the plant and office facilities
covering the period from January 1, 1996 to December 31, 2005. These new
operating leases provide for scheduled base rent increases over the term of the
lease, however, the total amount of the base rent payments will be charged to
operations using the straight-line method over the term of the lease. The leases
provide for payment

                        December 31, 1995, 1994 and 1993
of real estate taxes based upon a percentage of the annual increase. The
Company's subsidiaries, 51% H.R. Cenci Laboratories, Inc. ("Labs") and Cenci
Powder Products, Inc. ("Cenci"), lease plant and office facilities on a
month-to-month basis from an officer of the subsidiaries. Rent expense relating
to these leases amounted to approximately $86,000, $99,000 and $91,000 in 1995,
1994 and 1993, respectively. In addition, the Company rents certain equipment
under operating leases, generally for terms of four years. Total rent expense
for the years ended December 31, 1995, 1994 and 1993 was approximately $659,000,
$582,000 and $502,000, respectively.
 
  The approximate minimum rental commitments under these operating leases are as
follows:
 

Twelve months ending December 31,       (in thousands)

  On January 1, 1993, the Company entered into an employment agreement with an
officer having an initial term of five years. On July 1, 1994, the Company
entered into an employment agreement with another officer having an initial term
of three years. These employment agreements contain change in control provisions
that would entitle each officer to receive certain severance benefits if there
is a change in control in the Company, as defined, and a termination of
employment. The maximum contingent liability as of December 31, 1995 under these
agreements is approximately $1,027,000.
 
NOTE M - CONTINGENCIES
 
  The Company currently is a defendant in several lawsuits involving product
liability and other claims. The Company's insurance carriers have assumed the
defense for all product liability and other actions involving the Company. None
of the lawsuits is brought as a class action. The ultimate outcome of these
lawsuits cannot be determined at this time, and accordingly, no adjustment has
been made to the consolidated financial statements.
 
  In April and May of 1990, the FDA conducted a pre-approval inspection of the
Company's facilities, certain pending approval applications and its
manufacturing procedures. The FDA issued "Inspectional Observations" and made
further investigations of the Company's recordkeeping practices and the accuracy
of certain records maintained by the Company during the research and development
stage for a single drug entity not being marketed by the Company. On July 29,
1991, the Company received a Federal grand jury subpoena for documents relating
to approved and unapproved ANDAs for various products and other documents
relating to the Company's operations.
 
  The Company received a letter dated October 25, 1991 from the FDA advising
that the FDA, under its fraud policy, had undertaken a validity assessment with
respect to the Company's ANDAs, including four pending ANDAs and various ANDA
supplements, pursuant to which all reviews are suspended. The Company
voluntarily undertook an internal audit and retained an outside consultant to
review pending and various filed and approved ANDAs. As part of that process,
the Company withdrew its ANDAs for the drug product, fenoprofen calcium.
 
  On June 29, 1993, the Company entered into a consent decree with the U.S.
Attorney for the Eastern District of New York on behalf of the FDA that resulted
from the FDA's investigation. Under the terms of the consent decree, the Company
was enjoined from shipping any solid dosage drug products (i.e., excluding
liquid drug formulations) manufactured at the Company's facilities until the
Company established, to the satisfaction of the FDA, that the methods used in,
and the facilities and controls to be used for, manufacturing, processing,
packing, labeling and holding any drug are established, operated and
administered in conformity with the Federal Food, Drug and Cosmetic Act and the
FDA's Current Good Manufacturing Practice regulations. As part of satisfying the
foregoing requirements, the Company is required to validate the manufacturing
processes for each solid dosage drug product prior to manufacturing and shipping
the drug product, except that the Company is permitted under the terms of the
consent decree to manufacture and ship from its facilities six identified drug
products at its own risk provided that: (i) at least twice per month, the
Company's independent expert certifies that each batch of drug

                        December 31, 1995, 1994 and 1993
product upon validation will have been manufactured in accordance with the FDA
Regulations and the formulation described in the drug products approved NDA
("New Drug Application") or ANDA, until such time as validation is completed for
these products; and (ii) for any batches of these products that have already
been manufactured, such certification will include certification by a company
representative with personal knowledge of the records relating to such drug that
they are accurate and complete and a certification signed by an independent
expert that he has personally reviewed the records provided and that in his
professional opinion, the foregoing requirement concerning validation has been
met. The Company commenced shipments of five of the six solid dosage products
under the foregoing certification process. After review by the Company and its
consultants of one of the Company's six core products, a hydrocone bitartrate
5mg and acetaminophen 500mg tablet, discrepancies were discovered with some of
the data in the Company's ANDA. This resulted in a voluntary recall of this
product and the withdrawal of the ANDA. For the fiscal years ended December 31,
1995, 1994 and 1993, the remaining five products accounted for approximately
61%, 63% and 49% of the total sales of the Company, respectively.
 
  During 1992, the Company understood that the Department of Justice ("DOJ") was
continuing to conduct an ongoing criminal investigation into the Company's
ANDAs, and related manufacturing and recordkeeping practices. In March of 1993,
the Company received a second Federal grand jury subpoena for documents relating
to two specific products and any other products manufactured by the Company for
which improper records may have been kept. As a result of the government's
investigation, the Company discovered certain product adulterations and
recordkeeping problems with five products manufactured at the Company's Brooklyn
plant. As a result of the above, for certain products, the Company indefinitely
ceased production, initiated a product recall and recorded a charge to
operations of approximately $5,935,000 for the year ended December 31, 1993,
consisting of inventory write-offs ($2,925,000), a recall of products sold
($950,000) and the DOJ settlement of $2,060,000, as discussed below. Included in
1993 net sales are sales of discontinued products of approximately $4,806,000.
 
  On June 21, 1993, the Company entered into a plea agreement with the DOJ to
resolve the government's investigation. Under the terms of the plea agreement,
the Company agreed to plead guilty to five counts of adulteration of a single
drug product shipped in interstate commerce and related recordkeeping
violations. The plea agreement also requires the Company to pay a fine of
$2,500,000 over five years in quarterly installments of $125,000 beginning
September 15, 1993. Accordingly, the Company has recorded a provision of
$2,060,000 (net of imputed interest). As of December 31, 1995, the Company has
only paid two quarterly installments and additional partial payments of $90,000.
The plea agreement stipulates that if the Company does not make timely payments,
the entire fine becomes due and payable. As a result, the entire DOJ settlement
has been reclassified as a current liability in the 1995 and 1994 consolidated
balance sheets. At the present time, no action has been initiated by the DOJ to
require immediate payment of the entire amount. Should the DOJ require immediate
payment, it could result in a material adverse impact on the financial condition
of the Company.
 
  On March 31, 1993, and April 1, 1993, five lawsuits were filed by shareholders
against the Company and three or more of the Company's directors. Each of the
actions alleged that the Company and its directors made misleading statements
and omissions relating to the prospects of the Company's business and products,
including products under development, as well as relating to the status of the
Department of Justice and FDA investigations. Each of the actions purported to
be brought on behalf of a class of the Company's shareholders. Also, on May 20,
1993 and October 14, 1993, two separate shareholders derivative lawsuits were
filed against the Company and three or more of the Company's directors. Each of
these lawsuits alleged that the Company and its directors concealed certain
government investigations by the FDA and the Department of Justice. These
actions also alleged that the directors breached their fiduciary duty in
connection with their dispositions of their share of the Company's common stock
on the basis of material information which was not publicly known. In June 1994,
the plaintiffs of the five lawsuits and the two shareholder-derivative lawsuits
and the Company agreed to a settlement of these lawsuits. The Company agreed to
pay to the plaintiffs $1,000,000 in cash, which has been paid by the Company's
insurance carrier and, at the Company's option, either (i) the issuance of
shares of the Company's common stock having a value, as of the date of
distribution, of $3,000,000 or (ii) the payment by the Company of $3,000,000 in
cash or (iii) any combination of issuance of shares or payment of cash by the
Company having a combined value as of the date of distribution of $3,000,000. In
November 1995, the Company satisfied the remainder of its settlement obligation
by issuing 824,742 shares of its common stock valued at $3,000,000 or $3.6375
per share.

                        December 31, 1995, 1994 and 1993
 
  On November 12, 1993, the Securities and Exchange Commission ("SEC") requested
that the Company provide to the SEC, on a voluntary basis, information and
documents regarding the ingredients and filings relating to the following drugs:
quinidine gluconate, propylthiourical, acetaminophen and codeine phosphate,
metronidazole, quinidine sulfate, and hydraliazine hydrochloride. The SEC
advised the Company that the inquiry relates to public information disseminated
by the Company and trading in the Company's securities during the period August
1987 through July 1993. The Company is cooperating with the SEC and has made
available various documents. These documents relate to the testing, formulations
and sale of these drugs which were maintained by the Company at the offices of
its counsel in Maryland. In April 1994, the SEC requested additional
documentation regarding these matters. The Company has complied with the
additional request. On July 5, 1994, the Company made a formal submission to the
SEC and outlined the parameters of a proposed settlement. An additional
submission was made on January 31, 1995 to bring additional information to the
SEC. In May 1995, a formal Order of Investigation was issued by the SEC covering
the foregoing matters. In June 1995, additional documents were submitted.
Officers and directors of the Company have also testified before the SEC. On
October 24, 1995, the SEC staff informed the Company that it would recommend
that the Commission authorize the institution of an administrative proceeding
pursuant to Section 21C of the Securities Exchange Act of 1934 (the "Exchange
Act") against the Company. Specifically the staff indicated it would seek an
Order after filing a complaint requiring the Company to cease and desist from
violating Section 17(a) of the Securities Act and Sections 10(b) and 13(a) of
the Exchange Act and Rules 10b-5, 12b-20, 13a-1 and 13a-13 thereunder. The
proposed action would allege that the Company's December 31, 1990 and December
31, 1991 Annual Reports on Form 10-K and March 31, 1991, June 30, 1991,
September 30, 1991, March 31, 1992, June 30, 1992 and September 30, 1992
quarterly reports on Form 10-Q were materially false and misleading. The SEC
staff proposal conforms in large part to the settlement proposal submitted by
the Company. Under this proposal, the Company, without admitting the allegations
would then enter into a Consent Decree not to violate the law in the future. The
Company is unable to predict the ultimate outcome of the SEC adopting the staff
proposal although the SEC has indicated that it anticipates such action. An
adverse determination in this regard could have a material adverse effect on the
Company's financial condition. The Company is unable to predict the likelihood
of an unfavorable outcome as a result of this inquiry and, accordingly, no
provision has been made for any potential costs.
 
  A lawsuit has been filed by the minority shareholders of H.R. Cenci
Laboratories, Inc. and Cenci Powder Products, Inc. against the Company and
several of the officers of the Company. The lawsuit alleges that the Company has
breached several representations made during the course of negotiations leading
to the Company's purchase of 51% of the stock of H.R. Cenci Laboratories, Inc.
This action seeks unspecified compensatory damages, as well as punitive damages,
rescission, specific performance, reformation and a declaration as to what
amount, if any, is owed to plaintiff. Because of the early stage of this action,
it is not possible at this time to predict with reasonable certainty the
ultimate outcome of this matter and, accordingly, no provision has been made for
any potential costs relating to this matter.
 
NOTE N - SALE OF COMMON STOCK
 
  On March 30, 1995, the Company entered into an agreement with Zatpack which
provides for the purchase of 500,000 shares of common stock of the Company by
Zatpack, with registration rights, in consideration of $1,000,000. The
$1,000,000 consideration consists of the cancellation of indebtedness (incurred
by the Company's subsidiaries for the purchase of raw materials delivered from
affiliates of Zuellig) and shares of Indiana Fine Chemicals Corporation. As a
result of the above transaction, the Company owns 100% of Indiana Fine Chemical
Corporation (prior to the above transaction, the Company owned 70% of Indiana
Fine Chemical Corporation). In addition, the Company issued a convertible
promissory note to Zatpack, dated December 1, 1994 (Note E). Zatpack has
acquired the above assets from Zuellig and its subsidiaries.
 
  On October 27, 1994, the Company sold 500,000 shares of its common stock in
exchange for $1,000,000 from Ranbaxy Pharmaceuticals, Inc. ("Ranbaxy"). In
connection with these shares, Ranbaxy had the right to have its shares of the
Company's common stock registered under the Securities Act of 1993. In July
1995, the Company repurchased the 500,000 shares from Ranbaxy for $1,100,000.

                        December 31, 1995, 1994 and 1993
 
NOTE O - SIGNIFICANT CUSTOMERS AND SUPPLIERS
 
  The Company sells its products to a large number of customers who are
primarily drug distributors, drug store chains and wholesalers and are not
concentrated in any specific region. The Company performs ongoing credit
evaluations of its customers and generally does not require collateral. During
1995, the Company had net sales to two customers in excess of 10% of total
sales, each aggregating 25% and 11% of total sales, respectively. During 1994,
the Company had net sales to three customers in excess of 10% of total sales,
each aggregating 12% of total sales. During 1993, the Company had net sales to
two customers in excess of 10% of total sales, each aggregating 12% of total
sales. Balances due from these customers were approximately 25% and 7% of total
accounts receivable at December 31, 1995 and 1994, respectively. The loss of any
of these customers could have a material adverse effect on the Company.
 
  During 1995, the Company purchased approximately $2,741,000 of its raw
materials from Mallinckrodt and amounts due this supplier represented
approximately 29.7% of accounts payable as of December 31, 1995. The federal
drug application process requires specification of raw materials suppliers. If
raw materials from a supplier specified in a drug application were to become
unavailable on commercially acceptable credit terms, FDA supplemental approval
of any new supplier would be required. In view of the FDA consent decree and the
suspension of review of the Company's ANDA by the FDA, the Company would be
unable to obtain FDA supplemental approval at the Brooklyn plant for a new
supplier except in very limited circumstances. The Drug Enforcement
Administration limits the quantity of the Company's inventories of certain raw
materials used in the production of controlled substances based on historical
sales data. These limitations could increase the likelihood of raw material
shortages and of manufacturing delays in the event the Company was required to
find new suppliers of these raw materials. There can be no assurance that the
Company will not face difficulties in obtaining raw materials on commercially
acceptable terms, which could have a material adverse effect on the Company.
 
NOTE P - TEMPORARY CLOSING COSTS OF FACILITY
 
  As a result of irregularities identified in the manufacturing operations of
its 51%-owned subsidiary, H.R. Cenci Laboratories, Inc., the Company, in July
1994, ceased all manufacturing and sales activities at H.R. Cenci Laboratories,
Inc. The Company, upon completion of its review and modifications at the
facility, reopened H.R. Cenci Laboratories, Inc. in January 1996. In connection
with this temporary closure, the Company recorded costs of $615,000 and $427,000
for the years ending December 31, 1995 and 1994, respectively. These costs
consist of inventory write-offs, utilities, security and rent.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
    Section 722 of the New York Business Corporation Law (the "BCL") provides
that a corporation may indemnify directors and officers as well as other
employees and individuals against judgments, fines, amounts paid in settlement
and reasonable expenses, including attorneys' fees, in connection with actions
or proceedings, whether civil or criminal (other than an action by or in the
right of the corporation--a "derivative action"), if they acted in good faith
and in a manner they reasonably believed to be in or not opposed to the best
interests of the corporation, and, with respect to any criminal action or
proceeding, had no reasonable cause to believe their conduct was unlawful. A
similar standard is applicable in the case of derivative actions, except that
indemnification only extends to amounts paid in settlement and reasonable
expenses (including attorneys' fees) incurred in connection with the defense or
settlement of such actions, and the statute does not apply in respect of a
threatened action, or a pending action that is settled or otherwise disposed of,
and requires court approval before there can be any indemnification where the
person seeking indemnification has been found liable to the corporation. Section
721 of the BCL provides that Article 7 of the BCL is not exclusive of other
indemnification that may be granted by a corporation's certificate of
incorporation, disinterested director vote, stockholder vote, agreement or
otherwise. The Registrant's by-laws requires the Registrant to indemnify its
officers and directors to the fullest extent permitted under the BCL.
 
    The Registrant's by-laws provides that no director of the Registrant shall
be personally liable to the Registrant or its shareholders for monetary damages
for breach of fiduciary duty as a director, except that no indemnification shall
be made in respect of (1) a threatened action, or a pending action which is
settled or otherwise disposed of, or (2) any claim, issue or matter as to which
such person shall have been adjudged to be liable to the Registrant unless and
only to the extent that the court in which such action or suit was brought or,
if no action was brought, any court of competent jurisdiction determines upon
application that, in view of all the circumstances of the case, such person is
fairly and reasonably entitled to indemnity for such portion of the settlement
and expenses as the court deems proper.
 
    Any amendment to or repeal of the Registrant's certificate of incorporation
or by-laws shall not adversely affect any right or protection of a director of
the Registrant for or with respect to any acts or omissions of such director
occurring prior to such amendment or repeal.
 
ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES.
 
    Since April 1, 1993, the Registrant has issued the following unregistered
securities:
 
                                      II-1
<PAGE>
    (a) During the period 1993 through September 1995, the Registrant issued an
aggregate of 635,653 Common Stock purchase warrants ("Bank Warrants") to three
commercial banks in connection with several amendments to the Registrant's
credit agreement with these banks. The Bank Warrants have exercise prices
ranging from $2.13 to $2.275 per share, and are exercisable until July 17, 2000.
 
    (b) On March 30, 1995, the Registrant signed an agreement (the "Zatpack
Agreement") with Zatpack, Inc. ("Zatpack"). The Zatpack Agreement provided for
the purchase of 500,000 shares of Common Stock of the Registrant (the "Zatpack
Shares") by Zatpack, a British Virgin Islands Registrant, in consideration of
$1,000,000. The $1,000,000 purchase price was comprised of a combination of
cancellation of indebtedness, primarily incurred by subsidiaries of the
Registrant for the purchase of raw materials previously delivered and in the
process of being delivered from affiliates of Zuellig Group N.A., Inc.
("Zuellig"), and surrender of shares of a subsidiary of the Registrant.
 
    Pursuant to the Zatpack Agreement, the Registrant issued a convertible
promissory note (the "Zatpack Note"), dated as of December 1, 1994, to Zatpack
as consideration for cancellation of additional indebtedness. This indebtedness
resulted from trade payables and advances to the Registrant by Zuellig and
certain of its subsidiaries. The Zatpack Note is in the original principal
amount of $1,292,242, with interest accruing at a rate of 8%, compounded
annually. The Zatpack Note is convertible into 681,737 shares of Common Stock
(the "Note Shares") of the Registrant at expiration at an adjusted conversion
price of $2.39 per share, subject to adjustment.
 
    (c) On October 27, 1994, the Registrant signed a Letter of Intent ("LOI")
with Ranbaxy Pharmaceuticals, Inc. ("RPI"), a wholly owned United States
subsidiary of Ranbaxy Laboratories Ltd. of New Delhi, India. The Registrant
received $1,000,000 from RPI in payment for 500,000 shares of Common Stock (the
"RPI Shares") in accordance with the terms of the LOI. The LOI provided for
completion of due diligence by RPI within a period of 30 days, after which the
parties would negotiate and finalize a definitive agreement. After execution of
a definitive agreement, RPI was to have purchased an additional 500,000 newly
issued shares of Common Stock for $1,000,000. On November 29, 1994, the
Registrant announced that RPI had decided not to proceed with its second
purchase of the Registrant's Common Stock. In August 1995 the Registrant
repurchased the RPI Shares.
 
    (d) On July 18, 1995, the Registrant consummated a private offering (the
"July Private Offering") of 408 units ("Units") of securities for an aggregate
purchase price of $4,080,000. Each Unit consisted of (i) a debenture ("July
Debenture") in the principal amount of $10,000 issued at par and (ii) 750
redeemable Common Stock purchase warrants ("July Redeemable Warrants").
 
    The July Debentures will become due and payable as to principal on July 18,
2000. Interest, at the rate of 10% per annum, is payable on a quarterly basis.
The July Debentures are convertible at any time after issuance into Underlying
Shares at a conversion price (the "Conversion Price") of $2.00 per share,
subject to adjustment, through July 18, 2000.
 
    Each July Redeemable Warrant entitles the holder to purchase one Underlying
Share for $2.00 at any time after issuance through July 18, 2000. The July
Redeemable Warrants are redeemable by the Registrant at a price of $.01 per July
Redeemable Warrant at any time commencing one year after issuance, upon not less
than 30 days prior written notice, if the last sale price of the Common Stock on
the American Stock Exchange, Inc. following such one year anniversary equals or
exceeds $2.00 per share for the 20 consecutive trading days ending on the third
day prior to the notice of redemption to holders.
 
    The net proceeds of the July Private Offering was approximately $3,728,175.
The Registrant utilized $1,100,000 of such proceeds to repurchase the RPI
Shares.
 
                                      II-2
<PAGE>
    Subscriptions for Units were solicited by management of the Registrant on a
'best efforts' basis. HKS & Co., Inc. ("HKS") assisted the Registrant in the
July Private Offering. For its services, the Registrant paid HKS a fee of
$204,000, and reimbursed HKS in the amount of approximately $20,000 for its
expenses.
 
    The following table sets forth certain information regarding the investors
in the July Private Offering:

    (e) On November 29, 1995, the Registrant consummated a private offering (the
"November Private Offering") of 366 Units for an aggregate purchase price of
$3,660,000. Each Unit consisted of (i) a debenture ("November Debenture") in the
principal amount of $10,000 issued at par and (ii) 600 redeemable Common Stock
purchase warrants ("November Redeemable Warrants").
 
    The November Debentures will become due and payable as to principal on
November 29, 2000. Interest, at the rate of 10% per annum, is payable on a
quarterly basis. The November Debentures are convertible at any time after
issuance into Underlying Shares at a Conversion Price of $2.50 per share,
subject to adjustment, through November 29, 2000.
 
    Each November Redeemable Warrant entitles the holder to purchase one
Underlying Share for $2.50 at any time after issuance through November 29, 2000.
The November Redeemable Warrants are redeemable by the Registrant at a price of
$.01 per November Redeemable Warrant at any time commencing one year after
issuance, upon not less than 30 days prior written notice, if the last sale
price of the Common Stock on the American Stock Exchange, Inc. following such
one year anniversary equals or exceeds $2.50 per share for the 20 consecutive
trading days ending on the third day prior to the notice of redemption to
holders.
 
    The net proceeds of the November Private Offering was approximately
$3,388,500.
 
    Subscriptions for Units were solicited by management of the Registrant on a
'best efforts' basis. HKS assisted the Registrant in the November Private
Offering. For its services, the Registrant paid HKS a fee of $188,000, and
reimbursed HKS in the amount of approximately $20,000 for its expenses.

    (f) In March 1996 the Registrant agreed to issue 25,597 shares of Common
Stock to Kahn Consulting, Inc. ("KCI") in settlement of outstanding invoices for
services rendered by KCI to the Registrant. The aggregate purchase price of the
shares was $100,000.
 
    (g) In March 1996 the Registrant issued 49,166 shares of Common Stock to
George and Julia E. Krsek in settlement of amounts allegedly owed by the
Registrant to the Krseks. The aggregate purchase price of the shares was
$184,375.
 
    (h) In April and May 1996, the Registrant issued 298,500 shares of Common
Stock upon the exercise of July Redeemable Warrants and 219,000 shares of Common
Stock upon the exercise of November Redeemable Warrants. These shares were
issued to each of the investors set forth in (d) and (e) above other than

    In each case above, the securities were issued in reliance upon the
exemption from registration provided by Section 4(2) of the Securities Act of
1933, as amended (the "Securities Act"). In issuing securities under the
exemption from registration provided by Section 4(2) of the Securities Act, the
Registrant relied on representations made by each purchaser that such purchaser
was either an "accredited investor," as such term is defined by Rule 501 of
Regulation D under the Securities Act, or that such purchaser had such knowledge
and experience in business and financial matters that such person was capable of
evaluating the merits and risks of the investment.

ITEM 17. UNDERTAKINGS.
 
    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 of whether such
indemnification by it is against public policy as expressed in the Securities
Act and will be governed by the final adjudication of such issue.
 
    The undersigned Registrant hereby undertakes that:
 
    (1) For the purpose of determining any liability under the Securities Act,
the information omitted from the form of prospectus filed as part of this
Registration Statement in reliance upon Rule 430A and contained in a form of
prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or 497(h)
under the Securities Act, shall be deemed to be part of this Registration
Statement as of the time it was declared effective.
 
    (2) For the purpose of determining any liability under the Securities Act,
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.
 
    The undersigned Registrant hereby undertakes:
 
    (1) To file, during any period in which offers or sales are being made, a
post-effective amendment to this registration statement:
 
    (i) To include any prospectus required by section 10(a)(3) of the Securities
Act of 1933;
 
    (ii) To reflect in the prospectus any facts or events arising after the
effective date of the registration statement (or the most recent post-effective
amendment thereof) which, individually or in the aggregate, represent a
fundamental change in the information set forth in the registration statement;
and
 
                                      II-7
<PAGE>
    (iii) To include any material information with respect to the plan of
distribution not previously disclosed in the registration statement or any
material change to such information in the registration statement.
 
    (2) That, for the purpose of determining any liability under the Securities
Act of 1933, each such post-effective amendment 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.
 
    (3) To remove from registration by means of a post-effective amendment any
of the securities being registered which remain unsold at the termination of the
offering.
