                                   THE COMPANY

OVERVIEW

         We are a multinational company engaged in the research, development,
manufacture and marketing of pharmaceutical products. We have grown through the
development of proprietary and brand-equivalent products and through strategic
acquisitions, focused primarily on countries whose pharmaceutical markets are
developing, where there is the greatest growth potential.

         Our full line of brand-equivalent drugs includes the first United
States Food and Drug Administration (FDA) approved equivalent to branded
Taxol(R), a $1.5 billion oncology drug, and we have marketing applications
pending for many other products that are equivalent to important branded drugs.
Based on our unique patented inhalers, we have built a strong franchise in the
asthma market, and we are expanding that franchise by conducting studies to
support marketing applications for respiratory products in the United States and
in other markets served by our global marketing network. Our product pipeline
also includes novel compounds that we have discovered or licensed from third
parties, some of which have already successfully completed Phase II clinical
trials and are now undergoing Phase III trials, which is the final step before
submission of applications for marketing approval.

         Our business has grown significantly during the past year. During 2000,
we generated net revenues of $793 million, up from $656 million in 1999, and net
income of $131 million, up from $71 million in 1999.

GROWTH STRATEGIES

         We expect our future growth to come from the following:

         -        Discovering and Developing and/or Acquiring New Products. In
                  October 1999, we dramatically increased the size and scope of
                  our new product development capability through our acquisition
                  of an independent research company, now known as IVAX Drug
                  Research Laboratories, Ltd. We are committed to the
                  cost-effective development of


                                       1


                  proprietary pharmaceuticals directed primarily toward
                  indications having relatively large patient populations or for
                  which limited or inadequate treatments are available. We seek
                  to accelerate product development and commercialization by
                  in-licensing compounds, especially after clinical testing has
                  begun, and by developing new dosage forms or new therapeutic
                  indications for existing products.

         -        Leveraging Proprietary Technology and Development Strengths.
                  We intend to continue to leverage our proprietary technology
                  and development strengths, including our patented inhalation
                  technology and our expertise in developing and commercializing
                  respiratory products and experience in the development and
                  commercialization of oncology drugs to develop a significant
                  portfolio of proprietary, high value pharmaceutical products.

         -        Pursuing Complementary, Accretive or Strategic Acquisitions.
                  We intend to pursue accretive or strategic business
                  acquisitions or ones that will complement our existing
                  businesses and provide new product and market opportunities,
                  as well as leverage our existing assets. In addition, we will
                  continue to actively pursue strategic product acquisitions and
                  other collaborative arrangements that permit us to leverage
                  our existing infrastructure by adding sales from acquired
                  products while minimizing incremental costs.

         -        Strategically Expanding Sales and Distribution of Our
                  Products. We recently completed acquisitions of pharmaceutical
                  companies in Venezuela, Mexico and Chile and continue the
                  expansion of our Latin American operations. Our future plans
                  include (1) acquiring additional manufacturing and
                  distribution capabilities in Europe and Latin America and (2)
                  establishing additional joint ventures and selectively
                  establishing distribution channels for our major products in
                  Asia.

PHARMACEUTICAL BUSINESS

         We have pharmaceutical manufacturing facilities located in Argentina,
Chile, China, the Czech Republic, England, Germany, Hungary, Ireland, Mexico,
Peru, Puerto Rico, the United States, Uruguay, Venezuela and the Virgin Islands.
Marketing and/or research facilities are located in these same countries, and
also in Canada, France, India, Kazakhstan, Latvia, The Netherlands, Poland,
Russia, Sweden, Switzerland, The Slovak Republic, Taiwan and the Ukraine. In
other countries, our products are marketed through distributors or joint
ventures. Our pharmaceutical business has grown through the development and
acquisition of proprietary, brand-equivalent and over-the-counter pharmaceutical
products, the licensing of technology and products from third parties, and the
acquisition of companies engaged in the pharmaceuticals business in various
geographic regions.

         Proprietary and Branded Products

         We market a number of proprietary and branded products treating a
variety of conditions through our subsidiaries throughout the world. These
products are marketed by our direct sales force to physicians, pharmacies,
hospitals, managed health care organizations and government agencies. These
products are sold primarily to wholesalers, retail pharmacies, distributors,
hospitals and physicians.

         We have a strong foundation in the oncology field based on our
proprietary anti-cancer drug PAXENE(R) (paclitaxel injection), which is
therapeutically equivalent to the Bristol-Myers Squibb product Taxol(R), the
largest selling anti-cancer drug in the world. In September 2000, the FDA
approved our Abbreviated New Drug Application (ANDA) for paclitaxel, which is
marketed in the U.S. as Onxol(TM).


                                       2


         We also have substantial expertise in the development, manufacture and
marketing of respiratory drugs, primarily for asthma, in metered-dose inhaler
formulations. Our subsidiary in the United Kingdom is the third largest
respiratory company in that market. At the core of our respiratory franchise are
advanced delivery systems, which include a patented metered-dose inhaler called
Easi-Breathe(R), and a unique new dry powder inhaler, as well as conventional
metered-dose inhalers.

         Brand-Equivalent Products

         In the United States, we manufacture and market approximately 56
brand-equivalent prescription drugs in capsule or tablet forms in an aggregate
of 123 dosage strengths. We also distribute in the United States approximately
282 additional brand-equivalent prescription and over-the-counter drugs and
vitamin supplements, in various dosage forms, dosage strengths and package
sizes. We are also a leading provider of brand-equivalent pharmaceuticals in the
United Kingdom. We market approximately 110 brand-equivalent prescription and
over-the-counter drugs, about half of which we manufacture, in various dosage
forms and dosage strengths, constituting an aggregate of approximately 229
products. In addition, we manufacture and market various "blow-fill-seal"
pharmaceutical products, such as solutions for injection or irrigation, and
unit-dose vials for nebulization to treat respiratory disorders.

OTHER BUSINESSES

        Nutraceuticals. We provide contract manufacturing services for the
nutritional supplement industry from our encapsulating facility in Miami,
Florida. Utilizing herbal extracts manufactured by our Czech Republic
subsidiary, we also manufacture a line of high quality herbal nutraceutical
products in soft gelatin capsules.

        Veterinary Products. We formulate, package and distribute to
veterinarians various products for companion animals under the "DVM
Pharmaceuticals" trade name. Capitalizing on our proprietary research for human
pharmaceuticals, DVM Pharmaceuticals is developing proprietary products in the
therapeutic areas of asthma, gastrointestinal disorders and skin conditions in
horses and companion animals.

         Diagnostics. We own approximately 70% of the equity of IVAX
Diagnostics, Inc., a publicly traded company whose stock is listed on the
American Stock Exchange under the symbol "IVD." IVAX Diagnostics, Inc. develops,
manufactures and markets proprietary diagnostic reagents, instrumentation and
software through its subsidiaries located in the United States and Italy. Its
products include Mago(R) instruments and related diagnostic kits, as well as
autoimmune reagents and other in vitro diagnostic products for use in research,
clinical and hospital laboratories.

                               RECENT DEVELOPMENTS

         On July 5, 2001, we acquired, through tender offers, 99.6% of the
outstanding shares of Laboratorio Chile S.A., a Chilean pharmaceutical company
with operations in Chile, Argentina and Peru. On September 17, 2001, we
completed our tender offers for the remaining outstanding shares. As a result of
the two offers, we acquired 99.9% of the outstanding shares of Laboratorio
Chile, for an aggregate consideration of approximately US$395 million.
Laboratorio Chile is the largest Chilean pharmaceutical company in revenue terms
and is also among the major pharmaceutical companies in Argentina and Peru.
Laboratorio Chile manufactures and/or markets a broad line of more than 900
branded and brand-equivalent products in Chile, Argentina and Peru and reported
revenues of over US$173 million in 2000. Laboratorio Chile's main products are
to treat respiratory and infectious diseases, but it also has strong franchises
with cardiovascular, neurological and gynecologic products. We believe that
Laboratorio Chile, as well as our current operations in Argentina, Mexico, Peru,
Uruguay and Venezuela, create an


                                       3


excellent platform from which to launch our proprietary and brand-equivalent
pharmaceutical products, as well as products from other companies which may not
be so well represented in Latin America.

         On October 16, 2001, we announced the completion of our acquisition of
the intranasal steroid brand products, Nasarel(R) and Nasalide(R), from Elan
Corporation, plc. These products are for the treatment of allergic rhinitis
which affects more than 25% of the U.S. population. We will immediately begin
marketing these products in the U.S. through our subsidiary, IVAX Laboratories,
Inc. (f/k/a Wakefield Pharmaceuticals).

         On October 25, 2001, we announced our financial results for the third
quarter ended September 30, 2001. Net income for the third quarter of 2001 was
$61.5 million, or $.30 per diluted share, representing an increase of 99% over
net income of $30.9 million, or $.15 per diluted share, reported in the third
quarter of 2000. Our net income also includes nearly $7.1 million in gains on
the early retirement of debt. Net revenues for the third quarter of 2001
increased by 76% to $322.0 million as compared to net revenues of $182.6 million
in the third quarter of 2000.

                           PRINCIPAL EXECUTIVE OFFICES

         Our principal executive offices are located at 4400 Biscayne Boulevard,
Miami, Florida 33137, and our telephone number is (305) 575-6000.

                                  RISK FACTORS

         You should carefully consider the following risks before making an
investment decision. These and other risks could materially and adversely affect
our business, operating results or financial condition. You should also refer to
the other information contained or incorporated by reference in this prospectus,
before making an investment decision.

Risks Relating to Our Company

OUR RESEARCH AND DEVELOPMENT EXPENDITURES MAY NOT RESULT IN COMMERCIALLY
SUCCESSFUL PRODUCTS.

         We spent approximately $65.3 million during 2000 and $38.9 million
during the first six months of 2001 on our research and development efforts.
This amount represents a significant increase in the amounts we allocated to
research and development in prior periods. We may in the future increase the
amounts we expend for research and development. As a result, our research and
development expenditures may have an adverse impact on our earnings in the short
term. Further, we cannot be sure that our research and development expenditures
will, in the long term, result in the discovery or development of products which
prove to be commercially successful.

OUR POTENTIAL ACQUISITIONS MAY REDUCE OUR EARNINGS, BE DIFFICULT FOR US TO
COMBINE INTO OUR OPERATIONS OR REQUIRE US TO OBTAIN ADDITIONAL FINANCING.

         We search for and evaluate acquisitions which will provide new product
and market opportunities, benefit from and maximize our existing assets and add
critical mass. Acquisitions may expose us to additional risks and may have a
material adverse effect on our results of operations. Any acquisitions we make
may:

         -        fail to accomplish our strategic objectives;

         -        not be successfully combined with our operations;

         -        not perform as expected; and

         -        expose us to cross border risks.

         In addition, based on current acquisition prices in the pharmaceutical
industry, our acquisitions could initially reduce our per share earnings and add
significant intangible assets and related goodwill amortization charges. Our
acquisition strategy may require us to obtain additional debt or equity
financing, resulting in additional leverage, or increased debt obligations as
compared to equity, and dilution of ownership. We may not be able to finance
acquisitions on terms satisfactory to us.

WE DEPEND ON OUR DEVELOPMENT, MANUFACTURE AND MARKETING OF NEW PRODUCTS FOR OUR
FUTURE SUCCESS.

         Our future success is largely dependent upon our ability to develop,
manufacture and market commercially successful new pharmaceutical products and
brand-equivalent versions of pharmaceutical products that are no longer subject
to patents. Generally, the commercial marketing of pharmaceutical products
depends upon:

         -        continually developing and testing products;

         -        proving that new products are safe and effective in clinical
                  trials;


                                       5


         -        proving that there is no significant difference in the rate
                  and extent to which the active ingredient in the
                  brand-equivalent product becomes available at the site of drug
                  action as compared to the brand name version; and

         -        receiving requisite regulatory approval for all new products.

         Delays in the development, manufacture and marketing of new products
will impact our results of operations. Each of the steps in the development,
manufacture and marketing of our products, as well as the process taken as a
whole, involves significant periods of time and expense. We cannot be sure that:

         -        any of our products presently under development, if and when
                  fully developed and tested, will perform as we expect;

         -        we will obtain necessary regulatory approvals in a timely
                  manner, if at all; or

         -        we can successfully and profitably produce and market any of
                  our products.

WE DEPEND ON OUR PATENTS AND PROPRIETARY RIGHTS AND CANNOT BE CERTAIN OF THEIR
CONFIDENTIALITY AND PROTECTION.

         Our success with our proprietary products depends, in large part, on
our ability to protect our current and future technologies and products and to
defend our intellectual property rights. If we fail to adequately protect our
intellectual property, competitors may manufacture and market products similar
to ours. We have numerous patents covering our technologies. We have filed, and
expect to continue to file, patent applications seeking to protect newly
developed technologies and products in various countries, including the United
States. The United States Patent and Trademark Office does not publish patent
applications or make information about pending applications available to the
public until it issues the patent. Since publication of discoveries in the
scientific or patent literature tends to follow actual discovery by several
months, we cannot be certain that we were the first to file patent applications
on our discoveries. We cannot be sure that we will receive patents for any of
our patent applications or that any existing or future patents that we receive
or license will provide competitive advantages for our products. We also cannot
be sure that competitors will not challenge, invalidate or avoid the application
of any existing or future patents that we receive or license. In addition,
patent rights may not prevent our competitors from developing, using or selling
products that are similar or functionally equivalent to our products.

         We also rely on trade secrets, unpatented proprietary know-how and
continuing technological innovation. We use confidentiality agreements with
licensees, suppliers, employees and consultants to protect our trade secrets,
unpatented proprietary know-how and continuing technological innovation. We
cannot assure you that these parties will not breach their agreements with us.
We also cannot be certain that we will have adequate remedies for any breach.
Disputes may arise concerning the ownership of intellectual property or the
applicability of confidentiality agreements. Furthermore, we cannot be sure that
our trade secrets and proprietary technology will not otherwise become known or
that our competitors will not independently develop our trade secrets and
proprietary technology. We also cannot be sure, if we do not receive patents for
products arising from research, that we will be able to maintain the
confidentiality of information relating to our products.

THIRD PARTIES MAY CLAIM THAT WE INFRINGE THEIR PROPRIETARY RIGHTS AND MAY
PREVENT US FROM MANUFACTURING AND SELLING SOME OF OUR PRODUCTS.

         The manufacture, use and sale of new products that are the subject of
conflicting patent rights have been the subject of substantial litigation in the
pharmaceutical industry. These lawsuits relate to the validity and infringement
of patents or proprietary rights of third parties. We may have to defend against


                                       6


charges that we violated patents or proprietary rights of third parties. This is
especially true for the sale of the brand-equivalent version of products on
which the patent covering the branded product is expiring, an area where
infringement litigation is prevalent. Our defense against charges that we
infringed third party patents or proprietary rights could require us to incur
substantial expense and to divert significant effort of our technical and
management personnel. If we infringe on the rights of others, we could lose our
right to develop or make some products or could be required to pay monetary
damages or royalties to license proprietary rights from third parties.

         Although the parties to patent and intellectual property disputes in
the pharmaceutical industry have often settled their disputes through licensing
or similar arrangements, the costs associated with these arrangements may be
substantial and could include ongoing royalties. Furthermore, we cannot be
certain that the necessary licenses would be available to us on terms we believe
to be acceptable. As a result, an adverse determination in a judicial or
administrative proceeding or failure to obtain necessary licenses could prevent
us from manufacturing and selling a number of our products.

REDUCTIONS IN THE SALES VOLUME OR MARGINS OF OUR PACLITAXEL PRODUCT COULD IMPACT
OUR REVENUES AND MARGINS.

         Sales of our paclitaxel product represented a significant component of
our net revenues during the first nine months of 2001. In addition, an important
component of our 2001 and 2002 revenue and gross margin estimates depends on our
sales of paclitaxel. Recently, two competitors have received FDA approval for
the sale of their paclitaxel products and others may receive similar approvals.
Competitive pressures during the third quarter of 2001 have resulted in lower
prices and reduced revenues for our paclitaxel product. Our competitors and any
future competitors may continue to lower the price of such products and could
gain market share. Additionally, we currently rely on third parties to supply
raw materials for, and to manufacture, our paclitaxel products; in the future
these parties may not produce for us a continuing and reliable supply of
paclitaxel or the cost of such supply may significantly increase. The reduction
of the market price of paclitaxel, our loss of market share or our inability to
obtain a cost-effective supply of paclitaxel may result in a continued decrease
of net sales and gross margin from our paclitaxel product.

FUTURE INABILITY TO OBTAIN RAW MATERIALS OR PRODUCTS COULD SERIOUSLY AFFECT OUR
OPERATIONS.

         In many instances, we obtain raw materials and other products from
single domestic or foreign suppliers. Political disruptions have and may
continue to impact our ability to transport raw materials from foreign suppliers
and to ship finished goods worldwide. Additionally, many of the raw materials
utilized in our pharmaceutical products are rare or difficult to obtain.
Interruptions in supply or scarcity of raw materials would require us to seek to
obtain substitute materials or products, which, even if available, would require
additional regulatory approvals. Further, we cannot assure you that our third
party suppliers will continue to supply us. In addition, changes in our raw
material suppliers could result in delays in production, higher raw material
costs and loss of sales and customers because regulatory authorities must
generally approve raw material sources for pharmaceutical products. Any
significant interruption of supply could have a material adverse effect on our
operations.

MARKETING PRACTICES SUCH AS RETURNS, ALLOWANCES AND CHARGE-BACKS AND MARKETING
PROGRAMS ADOPTED BY WHOLESALERS MAY REDUCE SALES REVENUES IN SUBSEQUENT PERIODS.

         Based on industry practice, brand-equivalent manufacturers, including
us, have liberal return policies and have been willing to give customers
post-sale inventory allowances. Under these arrangements, the manufacturers give
customers credits on the manufacturer's brand-equivalent products which the
customers hold in inventory after decreases in the market prices of the
brand-equivalent


                                       7


products. Therefore, if new competitors enter the marketplace and significantly
lower the prices of any of our products, we would have to provide significant
credits that could reduce sales and gross margin. Like our competitors, we also
give credits for charge-backs to wholesale customers that have contracts with us
for their sales to hospitals, group purchasing organizations, pharmacies or
other retail customers. A charge-back is the difference between the price the
wholesale customer pays and the price that the wholesale customer's end-customer
pays for a product. Although we establish reserves based on our prior experience
and our best estimates of the impact that these policies may have in subsequent
periods, we cannot ensure that our reserves are adequate or that actual product
returns, inventory allowances and charge-backs will not exceed our estimates. In
the second quarter of 1996, based upon price declines at a time of significant
inventory levels, these credits were approximately $44 million higher than the
average levels that we experienced in prior quarters. Following our announcement
of the expected credits prior to the end of the second quarter, the market price
of our common stock immediately fell approximately 36%, and a number of persons
subsequently filed class action litigation against us based on the decline. That
class action litigation was resolved in our favor when the court dismissed it on
the merits.

THE CONCENTRATION OF OWNERSHIP AMONG OUR EXECUTIVE OFFICERS AND DIRECTORS MAY
PERMIT THOSE PERSONS TO INFLUENCE CORPORATE MATTERS AND POLICIES.

         As of September 30, 2001, our executive officers and directors
currently have or share voting control over approximately 21.72% of our issued
and outstanding common stock. As a result, these persons may have the ability to
significantly influence the election of the members of our board of directors
and other corporate decisions.

A NUMBER OF INTERNAL AND EXTERNAL FACTORS HAVE CAUSED AND MAY CONTINUE TO CAUSE
THE MARKET PRICE OF OUR STOCK TO BE VOLATILE.

         The market prices for securities of companies engaged in pharmaceutical
development, including us, have been volatile. Many factors, including many over
which we have no control, may have a significant impact on the market price of
our common stock, including without limitation:

         -        our or our competitors' announcement of technological
                  innovations or new commercial products;

         -        changes in governmental regulation;

         -        our or our competitors' receipt of regulatory approvals;

         -        our or our competitors' developments relating to patents or
                  proprietary rights;

         -        publicity regarding actual or potential medical results for
                  products that we or our competitors have under development;
                  and

         -        period-to-period changes in financial results.

POLITICAL AND ECONOMIC INSTABILITY AND FOREIGN CURRENCY FLUCTUATIONS MAY
ADVERSELY AFFECT THE REVENUES OUR FOREIGN OPERATIONS GENERATE.

Our foreign operations may be affected by the following factors, among others:

         -        political instability in some countries in which we currently
                  do business or may do business in the future through
                  acquisitions or otherwise;

         -        uncertainty as to the enforceability of, and government
                  control over, commercial rights;

         -        expropriation by foreign governmental entities; and

         -        currency exchange fluctuations and currency restrictions.


                                       8


         We sell products in many countries that are susceptible to significant
foreign currency risk. We sell many of these products for United States dollars,
which eliminates our direct currency risk but increases our credit risk if the
local currency devalues significantly and it becomes more difficult for
customers to purchase the United States dollars required to pay us. We sell a
growing number of products, particularly in Latin America, for local currency,
which results in a direct currency risk to us if the local currency devalues
significantly. Additional foreign acquisitions may increase our foreign currency
risk and the other risks identified above.

         On June 20, 2000, we announced our acquisition of Laboratorios Elmor
S.A., a pharmaceutical company based in Venezuela. Venezuela was considered to
have a highly inflationary economy, but it is no longer considered highly
inflationary. In the third quarter of 2001, we acquired 99.9% of Laboratorio
Chile S.A., a Chilean pharmaceutical company with operations in Chile, Argentina
and Peru. Although neither Chile nor Argentina have been classified as having
highly inflationary economies, each of these economies has experienced strong
inflation rates and devaluation of their respective currencies.

INCREASED INDEBTEDNESS MAY IMPACT OUR FINANCIAL CONDITION AND RESULTS OF
OPERATIONS.

         On June 30, 2001, we had approximately $1,003.6 million of consolidated
indebtedness. We may incur additional indebtedness in the future. Our level of
indebtedness will have several important effects on our future operations,
including, without limitation:

         -        we will be required to use a portion of our cash flow from
                  operations for the payment of any principal or interest due on
                  our outstanding indebtedness;

         -        our outstanding indebtedness and leverage will increase the
                  impact of negative changes in general economic and industry
                  conditions, as well as competitive pressures; and

         -        the level of our outstanding debt may affect our ability to
                  obtain additional financing for working capital, capital
                  expenditures or general corporate purposes.

         General economic conditions, industry cycles and financial, business
and other factors affecting our operations, many of which are beyond our
control, may affect our future performance. As a result, these and other factors
may affect our ability to make principal and interest payments on our
indebtedness. We anticipate that approximately $52 million of cash flow from
operations will be required each year to discharge our annual obligations on our
currently outstanding indebtedness. Our business might not continue to generate
cash flow at or above current levels. If we cannot generate sufficient cash flow
from operations in the future to service our debt, we may, among other things:

         -        seek additional financing in the debt or equity markets;

         -        refinance or restructure all or a portion of our indebtedness;

         -        sell selected assets; or

         -        reduce or delay planned capital expenditures.

         These measures might not be sufficient to enable us to service our
debt. In addition, any financing, refinancing or sale of assets might not be
available on economically favorable terms.


                                       9


COMPLIANCE WITH GOVERNMENTAL REGULATION IS CRITICAL TO OUR BUSINESS.

         Our pharmaceutical and diagnostic operations are subject to extensive
regulation by governmental authorities in the United States and other countries
with respect to the testing, approval, manufacture, labeling, marketing and sale
of pharmaceutical and diagnostic products. We devote significant time, effort
and expense to addressing the extensive government regulations applicable to our
business. In general, the trend is toward more stringent regulation.

         On an ongoing basis, the FDA reviews the safety and efficacy of
marketed pharmaceutical products and products considered medical devices and
monitors labeling, advertising and other matters related to the promotion of
such products. The FDA also regulates the facilities and procedures used to
manufacture pharmaceutical and diagnostic products in the United States or for
sale in the United States. Such facilities must be registered with the FDA and
all products made in such facilities must be manufactured in accordance with
"good manufacturing practices" established by the FDA. Compliance with good
manufacturing practices guidelines requires the dedication of substantial
resources and requires significant costs. The FDA periodically inspects our
manufacturing facilities and procedures to assure compliance. The FDA may cause
a recall or withdraw product approvals if regulatory standards are not
maintained. The FDA approval to manufacture a drug is site-specific. In the
event an approved manufacturing facility for a particular drug becomes
inoperable, obtaining the required FDA approval to manufacture such drug at a
different manufacturing site could result in production delays, which could
adversely affect our business and results of operations.

         In connection with our activities outside the United States, we are
also subject to regulatory requirements governing the testing, approval,
manufacture, labeling, marketing and sale of pharmaceutical and diagnostic
products, which requirements vary from country to country. Whether or not FDA
approval has been obtained for a product, approval of the product by comparable
regulatory authorities of foreign countries must be obtained prior to marketing
the product in those countries. The approval process may be more or less
rigorous from country to country, and the time required for approval may be
longer or shorter than that required in the United States. Our inability or
delay in receiving or the loss of any approval could have a material adverse
effect on our results of operations.

WE HAVE ENACTED A SHAREHOLDER RIGHTS PLAN AND CHARTER PROVISIONS THAT MAY HAVE
ANTI-TAKEOVER EFFECTS.

         We have in place a shareholder rights plan under which we issued common
stock purchase rights. As a result of the plan, each share of our common stock
carries with it one common stock purchase right. Each common stock purchase
right entitles the registered holder to purchase from us .9375 of a share of our
common stock at a price of $12.00 per .9375 of a share, subject to adjustment.
The common stock purchase rights are intended to cause substantial dilution to a
person or group who attempts to acquire us on terms that our board of directors
has not approved. The existence of the common stock purchase rights could make
it more difficult for a third party to acquire a majority of our common stock.
Other provisions of our articles of incorporation and bylaws may also have the
effect of discouraging, delaying or preventing a merger, tender offer or proxy
contest, which could have an adverse effect on the market price of our common
stock.

Risks Relating to Our Industry

OUR REVENUES AND PROFITS FROM BRAND-EQUIVALENT PHARMACEUTICALS WILL DECLINE AS
WE OR OUR COMPETITORS INTRODUCE ADDITIONAL BRAND-EQUIVALENTS OF THOSE PRODUCTS.

         Revenues and gross profit derived from brand-equivalent pharmaceutical
products tend to follow a pattern based on regulatory and competitive factors
unique to the brand-equivalent pharmaceutical industry. As patents for brand
name products and the related exclusivity periods established by regulation
expire, the first brand-equivalent manufacturer to apply for regulatory approval
for a brand-equivalent of a brand name product may be entitled to a 180-day
period of marketing exclusivity under the Hatch-Waxman Act. During this
exclusivity period, the United States Food and Drug Administration, or FDA,
cannot approve any other brand-equivalent. If we are not the first
brand-equivalent applicant, our brand-equivalent product will be kept off the
market for an additional 180 days after the brand name drug's patents expire.
Whether due to the 180-day period of marketing exclusivity or other factors that
delay the approval of other brand-equivalent competitors, the first
brand-equivalent on the market is usually able to initially achieve relatively
high revenues and gross profit. As other brand-equivalent manufacturers receive
regulatory approvals on competing products, prices and revenues typically
decline. The timing of these declines is unpredictable and can result in a
significantly curtailed period of profitability for a brand-equivalent product.
The level of revenues and gross profit attributable to brand-equivalent products
that we develop and manufacture is dependent, in part, on:

         -        our ability to develop and introduce new brand-equivalent
                  products;

         -        the timing of regulatory approval of brand-equivalent
                  products;

         -        the number and timing of regulatory approvals of competing
                  products;

         -        strategies brand name companies adopt to maintain their market
                  share; and

         -        our cost of manufacturing.

         Brand-equivalent products (but not including branded brand-equivalent
products) represented 49%, 56% and 51% of our revenues for the years ended
December 31, 2000, 1999 and 1998, respectively.

LEGISLATIVE PROPOSALS, REIMBURSEMENT POLICIES OF THIRD PARTIES, COST CONTAINMENT
MEASURES AND HEALTH CARE REFORM COULD AFFECT THE MARKETING, PRICING AND DEMAND
FOR OUR PRODUCTS.

         Various legislative proposals, including proposals relating to
prescription drug benefits, could materially impact the pricing and sale of our
products. Further, reimbursement policies of third parties may affect the
marketing of our products. Our ability to market our products will depend in
part on reimbursement levels for the cost of the products and related treatment
established by health care providers, including government authorities, private
health insurers and other organizations, such as health maintenance
organizations, or HMOs, and managed care organizations, or MCOs. Insurance
companies, HMOs, MCOs, Medicaid and Medicare administrators and others are
increasingly challenging the pricing of pharmaceutical products and reviewing
their reimbursement practices. In addition, the following factors could
significantly influence the purchase of pharmaceutical products, which would
result in lower prices and a reduced demand for our products:

         -        the trend toward managed health care in the United States;

         -        the growth of organizations such as HMOs and MCOs;

         -        legislative proposals to reform health care and government
                  insurance programs; and

         -        price controls and non-reimbursement of new and highly priced
                  medicines for which the economic therapeutic rationales are
                  not established.


                                       11


THESE COST CONTAINMENT MEASURES AND HEALTH CARE REFORM PROPOSALS COULD AFFECT
OUR ABILITY TO SELL OUR PRODUCTS.

         The reimbursement status of a newly approved pharmaceutical product may
be uncertain. Reimbursement policies may not include some of our products. Even
if reimbursement policies of third parties grant reimbursement status for a
product, we cannot be sure that these reimbursement policies will remain in
effect. Limits on reimbursement could reduce the demand for our products. The
unavailability or inadequacy of third party reimbursement for our products would
reduce or possibly eliminate demand for our products. We are unable to predict
whether governmental authorities will enact additional legislation or regulation
which will affect third party coverage and reimbursement that reduces demand for
our products.

OUR INDUSTRY IS HIGHLY COMPETITIVE WHICH AFFECTS OUR PRODUCT SELECTION, PRICING,
GROSS PROFIT AND MARKET SHARE.

         The pharmaceutical industry is intensely competitive. Most or all of
the products that we sell or license will face competition from different
chemical or other agents intended to treat the same diseases. Our current and
future products will also face competition from traditional forms of drug
delivery and from advanced delivery systems others are developing. Our
competitors vary depending upon geographic regions, product categories, and
within each product category, upon dosage strengths and drug delivery systems.
Some of our major competitors are:

         -        3M

         -        Astra Zeneca

         -        Barr Laboratories

         -        Boehringer Ingelheim

         -        Bristol-Myers Squibb

         -        Geneva Pharmaceuticals

         -        Glaxo Wellcome

         -        Eli Lilly

         -        Mylan Pharmaceuticals

         -        Novartis Pharmaceuticals

         -        Schering-Plough

         -        Teva Pharmaceuticals

Our competitors may be able to develop products and processes competitive with
or superior to our own for many reasons, including that they may have:

         -        significantly greater financial resources;

         -        larger research and development and marketing staffs; or

         -        larger production facilities or extensive experience in
                  preclinical testing and human clinical trials.

         -        difficulties we may experience in product development;

         -        efficacy or safety concerns with respect to marketed products,
                  whether or not scientifically justified, leading to recalls,
                  withdrawals or declining sales;

         -        our ability to obtain new materials or products;

         -        our ability to identify potential acquisitions and to
                  successfully acquire and integrate such operations or
                  products;

         -        our failure to realize the anticipated benefits of the

                       RATIO OF EARNINGS TO FIXED CHARGES

The following table sets forth our consolidated ratio of earnings to fixed
charges for the years ended December 31, 1996, 1997, 1998, 1999 and 2000 and for
the six months ended June 30, 2001.

(1)      The dollar amounts of the coverage deficiency for the years ended
         December 31, 1996 and 1997 were $189.4 million and $160.5 million,
         respectively.

         The ratio of earnings to fixed charges was calculated by dividing
earnings by total fixed charges. Earnings consist of pretax income plus fixed
charges. Fixed charges consist of interest expense on all indebtedness
(including amortization of deferred debt issuance costs) and a portion of rent
expense (5-8%) estimated by management to be the interest component of such
rentals.

                         DESCRIPTION OF DEBT SECURITIES

         This prospectus describes the general terms and provisions of the debt
securities that we may offer by this prospectus. When we offer to sell a
particular series of debt securities, we will describe the specific terms of
that series in a supplement to this prospectus. We will also indicate in the
prospectus supplement whether the general terms and provisions that we describe
in this prospectus apply to that particular series of debt securities. For a
complete description of the material terms of a particular issue of debt
securities, you must refer to both the prospectus supplement relating to that
series and to the following description.

         If issued, we will issue the debt securities under an indenture between
us and U.S. Bank Trust National Association, as trustee. The indenture is
subject to, and governed by, the Trust Indenture Act of 1939. We have filed a
copy of the indenture as an exhibit to the registration statement of which this
prospectus forms a part. We have summarized the material portions of the
indenture below, but you should read the indenture for other provisions that may
be important to you. We qualify the following summary in its entirety by
reference to the provisions of the indenture.

GENERAL

         We will establish the terms of each series of debt securities that we
will issue under the indenture by a resolution of our board of directors. We
will detail the terms of the debt securities that we will offer in an officers'
certificate under the indenture or by a supplemental indenture. We will describe
the particular terms of each series of debt securities that we issue in a
prospectus supplement relating to that series.

         Under the indenture, we can issue an unlimited amount of debt
securities, including debt securities that are convertible into or exchangeable
for our other securities, including our common stock. We may issue the debt
securities:

         -        in one or more series;

         -        with the same or various maturities;

         -        at par;

         -        at a premium; or

         -        at a discount.

         For each series of debt securities that we offer, we will distribute a
prospectus supplement that will disclose:

         -        the initial offering price;

         -        the aggregate principal amount of that series of debt
                  securities;

         -        the title of the debt securities;

         -        any limit on the aggregate principal amount of the debt
                  securities;

         -        the date or dates on which we will pay the principal on the
                  debt securities;

         -        the annual rate or rates (which may be fixed or variable) or
                  the method used to determine the rate or rates (including any
                  commodity, commodity index, stock exchange index or financial
                  index) at which the debt securities will bear interest;

         -        the date or dates from which interest will accrue;

         -        the date or dates on which interest will commence and be
                  payable;

         -        any regular record date for the interest payable on any
                  interest payment date;

         -        the place or places where we will pay the principal, premium,
                  and interest with respect to the


                                       16


                  debt securities;

         -        whether the debt securities will be convertible into other
                  securities and the terms and conditions upon which the holder
                  of debt securities may convert the debt securities;

         -        the terms and conditions upon which we may redeem the debt
                  securities;

         -        any obligation we have to redeem or purchase the debt
                  securities under any sinking fund or similar provisions or at
                  the option of a holder of debt securities;

         -        the dates on which and the price or prices at which we will
                  repurchase the debt securities at the option of the holders of
                  debt securities and other detailed terms and provisions of
                  these repurchase obligations;

         -        the denominations in which we will issue the debt securities
                  will be issued, if we issue them other than denominations of
                  $1,000 and any integral multiple thereof;

         -        whether we will issue the debt securities in the form of
                  certificated debt securities or global securities, or the
                  portion of principal amount of the debt securities that we
                  must pay if the maturity date of the debt security
                  accumulates, if different than the principal amount;

         -        the currency of denomination of the debt securities;

         -        the designation of the currency, currencies or currency unit
                  in which we must pay the principal, premium and interest with
                  respect to the debt securities;

         -        if we must pay the principal, premium or interest on the debt
                  securities in one or more currencies or currency units other
                  than that or those in which the debt securities are
                  denominated, the manner in which we will determine the
                  exchange rate for these payments;

         -        the manner in which we will determine the amounts of the
                  principal, premium or interest we must pay on the debt
                  securities, if we will determine these amounts by reference to
                  an index based on a currency or currencies other than that in
                  which the debt securities are denominated or designated to be
                  payable or by reference to a commodity, commodity index, stock
                  exchange index or financial index;

         -        any provisions relating to any security that we will provide
                  for the debt securities;

         -        any addition to or change in the events of default that we
                  describe in this prospectus or in the indenture;

         -        any change in the acceleration provisions that we describe in
                  this prospectus or in the indenture;

         -        any addition to or change in the covenants described in this
                  prospectus or in the indenture with respect to the debt
                  securities;

         -        any other terms of the debt securities, which may modify or
                  delete any provision of the indenture as it applies to that
                  series; and

         -        any depositaries, interest rate calculation agents, exchange
                  rate calculation agents or other agents with respect to the
                  debt securities.

         We may issue debt securities that provide that we must only pay an
amount less than their stated principal amount if their maturity date
accelerates. In the prospectus supplement, we will also provide you with
information on the federal income tax considerations and other special
considerations which apply to any of the particular debt securities.

         If we denominate the purchase price of any of the debt securities in a
foreign currency or currencies or a foreign currency unit or units, or if we
must pay the principal, premium and interest with respect to any series of debt
securities in a foreign currency or currencies or a foreign currency unit or
units, we will provide you with information on the restrictions, elections,
general tax considerations, specific terms and other information with respect to
that issue of debt securities and the applicable foreign currency or currencies
or foreign currency unit or units in the applicable prospectus supplement.


                                       17


PAYMENT OF INTEREST AND EXCHANGE

         Each debt security will be represented by either:

         -        one or more global securities registered in the name of The
                  Depository Trust Company, or DTC, as depositary, or a nominee
                  of DTC, (a "book-entry debt security"); or

         -        a certificate issued in definitive registered form (a
                  "certificated debt security").

         We will describe whether the particular series of debt securities will
be a book-entry debt security or a certificated debt security in the applicable
prospectus supplement. Except as we describe under "Global Debt Securities and
Book-Entry System" below, we will not issue book-entry debt securities in
certificated form.

         Certificated Debt Securities. You may transfer or exchange
"certificated debt securities," debt securities evidenced by a certificate, at
the trustee's office or at paying agencies as we provide for in the indenture.
We will not charge you any service charge for any transfer or exchange of
certificated debt securities, but we may require you to pay of a sum sufficient
to cover any tax or other governmental charge that may be required in connection
with your transfer or exchange.

         You may transfer certificated debt securities and the right to receive
the principal, premium and interest on certificated debt securities only by
surrendering the certificate representing your certificated debt securities.
After you surrender your certificated debt securities. We or the trustee will
reissue your certificate to the new holder or we or the trustee will issue a new
certificate to the new holder.

         Global Debt Securities and Book-Entry System. A global debt security is
a debt security that represents, and is denominated in an amount equal to the
aggregate principal amount of, all outstanding debt securities of a series, or
any portion thereof, in either case having the same terms, including the same:

         -        original issue date;

         -        date or dates on which we must pay principal and interest; and

         -        interest rate or method of determining interest.

         We will deposit each global debt security representing book-entry debt
securities with, or on behalf of, the depositary. We will also register the
global debt security in the name of the depositary or its nominee. The
depositary has indicated it intends to follow the following procedures with
respect to book-entry debt securities.

         Only persons who have accounts with the depositary for the related
global debt security, or participants, or a person that holds an interest
through a participant may own beneficial interests in book-entry debt
securities. When we issue a global debt security, the depositary will credit, on
its book-entry registration and transfer system, the participants' accounts with
the appropriate principal amounts of the book-entry debt securities that the
participant owns. Any dealers, underwriters or agents participating in the
distribution of the book-entry debt securities will designate the accounts that
the depositary will credit. Ownership of book-entry debt securities will be
shown on, and the transfer of the ownership interests in book-entry debt
securities will be effected only through, records that the depositary maintains
for the related global debt security (for interests of participants) and records
that the participants maintain (for interests of persons holding through
participants). The laws of some states may require that some purchasers of
securities take physical delivery of their securities in definitive form. These
laws may impair the ability to own, transfer or pledge beneficial interests in
book-entry debt securities, since we


                                       18


will not issue book-entry debt securities in certificated form, except under the
special circumstances that we describe below.

         So long as the depositary, or its nominee, is the registered owner of a
global debt security, we will consider the depositary or its nominee as the sole
owner or holder of the book-entry debt securities represented by the associated
global debt security for all purposes under the indenture. Except as we describe
in this prospectus or the applicable prospectus supplement, beneficial owners of
book-entry debt securities will not be entitled to have securities registered in
their names and will not receive or be entitled to receive physical delivery of
a certificate in definitive form representing their securities. We will not
consider beneficial owners of book-entry debt securities the owners or holders
of those securities under the indenture. As a result, to exercise any rights of
a holder under the indenture, each person beneficially owning book-entry debt
securities must rely on the depositary's procedures for the related global debt
security and, if that person is not a participant, on the procedures of the
participant through which that person owns its interest.

         We understand, however, that under existing industry practice, the
depositary will authorize the persons on whose behalf it holds a global debt
security to exercise some rights of holders of debt securities, and the
indenture provides that we, the trustee and our respective agents will treat as
the holder of a debt security the persons specified in a written statement of
the depositary with respect to that global debt security for purposes of
obtaining any consents or directions required to be given by holders of the debt
securities under to the indenture.

         We will make payments of the principal, premium and interest on the
book-entry debt securities to the depositary or its nominee, as the case may be,
as the registered holder of the related global debt security. We, the trustee
and any other agent of ours or agent of the trustee will not have any
responsibility or liability for:

         -        any aspect of the records relating to or payments made on
                  account of beneficial ownership interests in a global debt
                  security; or

         -        maintaining, supervising or reviewing any records relating to
                  such beneficial ownership interests.

         We expect that the depositary, upon receipt of any payment of the
principal, premium or interest with respect to a global debt security, will
immediately credit the participants' accounts with payments in amounts
proportionate to the amounts of book-entry debt securities they each hold, as
shown on the records of the depositary. We also expect that payments by
participants to owners of beneficial interests in book-entry debt securities
held through those participants will be governed by standing customer
instructions and customary practices, as is now the case with the securities
held for the accounts of customers in bearer form or registered in "street
name," and will be the responsibility of those participants.

         We will issue certificated debt securities in exchange for each global
debt security if the depositary is at any time unwilling or unable to continue
as depositary or ceases to be a clearing agency registered under the Securities
Exchange Act of 1934, or the Exchange Act, and we do not appoint a successor
depositary registered as a clearing agency under the Exchange Act within 90
days. In addition, we may at any time and in our sole discretion determine not
to have any of the book-entry debt securities of any series represented by one
or more global debt securities and, in that event, we will issue certificated
debt securities in exchange for the global debt securities of that series.
Holders of global debt securities may exchange their global debt securities for
certificated debt securities if an event of default under the book-entry debt
securities represented by those global debt securities has occurred and is
continuing. We will register any certificated debt securities that we issue in
exchange for a global debt


                                       19

security in the name or names as the depositary shall instruct the trustee. We
expect that such instructions will be based upon directions received by the
depositary from participants with respect to ownership of book-entry debt
securities relating to such global debt security.

         We have obtained the previous information in this section concerning
the depositary and the depositary's book-entry registration and transfer system
from sources we believe to be reliable, but we take no responsibility for the
accuracy of this information.

CONSOLIDATION, MERGER AND SALE OF ASSETS

         Under the indenture we may not consolidate with or merge into, or
convey, transfer or lease all or substantially all of our properties and assets
to, any person, and we may not permit any person to merge into, or convey,
transfer or lease its properties and assets substantially as an entirety to us,
unless:

         -        the successor person is a corporation, partnership, trust or
                  other entity organized and validly existing under the laws of
                  any U.S. domestic jurisdiction and expressly assumes our
                  obligations on the debt securities and under the indenture;

         -        immediately after giving effect to the transaction, no event
                  of default, and no event which, after notice or lapse of time,
                  or both, would become an event of default, shall have occurred
                  and be continuing under the indenture; and

         -        we satisfy other conditions specified in the indenture.

COVENANTS

         Unless we state otherwise in:

         -        the applicable prospectus supplement and in a supplement to
                  the indenture;

         -        a resolution of our board of directors; or

         -        an officers' certificate delivered under the indenture

the debt securities will not contain any restrictive covenants, including
covenants restricting us or any of our subsidiaries from incurring, issuing,
assuming or guarantying any indebtedness secured by a lien on any of our or our
subsidiaries' property or capital stock, or restricting us or any of our
subsidiaries from entering into any sale and leaseback transactions.

EVENTS OF DEFAULT

         Under the indenture, an "event of default" means, with respect to any
series of debt securities, any of the following:

         -        our default in the payment of any interest on any debt
                  security of that series when it becomes due and payable, and
                  the continuance of that default for a period of 30 days
                  (unless we deposit the entire amount of the payment with the
                  trustee or with a paying agent prior to the expiration of the
                  30-day period);

         -        our default in the payment of principal or premium on any debt
                  security of that series when due and payable;

         -        our default in the deposit of any sinking fund payment, when
                  and as due on any debt security of that series;

         -        our default in the performance or breach of any of our other
                  covenants or warranties in the indenture (other than a
                  covenant or warranty that has been included in the indenture
                  solely for


                                       20


                  the benefit of a series of debt securities other than that
                  series), which default continues uncured for a period of 60
                  days after we receive written notice from the trustee or we
                  and the trustee receive written notice from the holders of at
                  least 25% in principal amount of the outstanding debt
                  securities of that series as provided in the indenture;

         -        some events of bankruptcy, insolvency or reorganization; and

         -        any other event of default provided with respect to debt
                  securities of that series that is described in the applicable
                  supplement to this prospectus.

         No event of default for a particular series of debt securities, except
for the events of default relating to events of bankruptcy, insolvency or
reorganization, will necessarily constitute an event of default for any other
series of debt securities.

         If an event of default under debt securities of any series occurs and
is continuing, then the trustee or the holders of not less than 25% in principal
amount of the outstanding debt securities of that series may, declare to be due
and payable immediately the principal (or, if the debt securities of that series
are discount securities, that portion of the principal amount as may be
specified in the terms of that series) and premium of all debt securities of
that series. In the case of an event of default resulting from events of
bankruptcy, insolvency or reorganization, the principal (or such specified
amount) and premium of all outstanding debt securities will become and be
immediately due and payable without any declaration or other act by the trustee
or any holder of outstanding debt securities. At any time after a declaration of
acceleration with respect to debt securities of any series, but before the
trustee has obtained a judgment or decree for payment of the money due, the
holders of a majority in principal amount of the outstanding debt securities of
that series may, subject to our having paid or deposited with the trustee a sum
sufficient to pay overdue interest and principal which has become due other than
by acceleration and certain other conditions, rescind and annul such
acceleration if all events of default, other than the non-payment of accelerated
principal and premium with respect to debt securities of that series, have been
cured or waived as provided in the indenture. For information as to waiver of
defaults see the discussion under "Modification and Waiver" below. We refer you
to the prospectus supplement relating to any series of debt securities that are
discount securities for the particular provisions relating to acceleration of a
portion of the principal amount of the discount securities upon the occurrence
of an event of default and the continuation of an event of default.

         The indenture provides that the trustee will be under no obligation to
exercise any of its rights or powers under the indenture at the request of any
holder of outstanding debt securities, unless the trustee receives indemnity
satisfactory to it against any loss, liability or expense. Subject to some
rights of the trustee, the holders of a majority in principal amount of the
outstanding debt securities of any series shall have the right to direct the
time, method and place of conducting any proceeding for any remedy available to
the trustee or exercising any trust or power conferred on the trustee with
respect to the debt securities of that series.

         No holder of any debt security of any series will have any right to
institute any proceeding, judicial or otherwise, with respect to the indenture
or for the appointment of a receiver or trustee, or for any remedy under the
indenture, unless:

         -        that holder has previously given to the trustee written notice
                  of a continuing event of default under the debt securities of
                  that series; and

         -        the holders of at least 25% in principal amount of the
                  outstanding debt securities of that series have made written
                  request, and offered reasonable indemnity, to the trustee to
                  institute such proceeding as trustee, and the trustee shall
                  not have received from the holders of a majority in principal
                  amount of the outstanding debt securities of that series a
                  direction inconsistent with


                                       21


                  that request and has failed to institute the proceeding within
                  60 days.

         Notwithstanding the foregoing, the holder of any debt security will
have an absolute and unconditional right to receive payment of the principal,
premium and any interest with respect to that debt security on or after the due
dates expressed in that debt security and to institute suit for the enforcement
of payment.

         The indenture requires us, within 90 days after the end of our fiscal
year, to furnish to the trustee a statement of our compliance with the
indenture. The indenture provides that the trustee may withhold notice to the
holders of debt securities of any series of any default or event or default
(except in payment on any debt securities of that series) with respect to debt
securities of that series if it in good faith determines that withholding notice
is in the interest of the holders of those debt securities.

MODIFICATION AND WAIVER

         We and the trustee may modify and amend the indenture with the consent
of the holders of at least a majority in principal amount of the outstanding
debt securities of each series affected by the modifications or amendments. We
and the trustee may not make any modification or amendment without the consent
of the holder of each affected debt security then outstanding if that amendment
will:

         -        change the amount of debt securities whose holders must
                  consent to an amendment or waiver;

         -        reduce the rate of or extend the time for payment of interest
                  (including default interest) on any debt security;

         -        reduce the principal of or premium on or change the fixed
                  maturity of any debt security or reduce the amount of, or
                  postpone the date fixed for, the deposit of any sinking fund
                  payment or analogous obligation with respect to any series of
                  debt securities;

         -        reduce the principal amount of discount securities payable
                  upon acceleration of maturity;

         -        waive a default in the payment of the principal, premium or
                  interest with respect to any debt security (except a
                  rescission of acceleration of the debt securities of any
                  series by the holders of at least a majority in aggregate
                  principal amount of the then outstanding debt securities of
                  that series and a waiver of the payment default that resulted
                  from that acceleration);

         -        make the principal, premium or interest with respect to any
                  debt security payable in currency other than that stated in
                  the debt security;

         -        make any change to certain provisions of the indenture
                  relating to, among other things, the right of holders of debt
                  securities to receive payment of the principal, premium and
                  interest with respect to those debt securities and to
                  institute suit for the enforcement of any payment and to
                  waivers or amendments; or

         -        waive a redemption payment with respect to any debt security
                  or change any of the provisions with respect to the redemption
                  of any debt securities.

         Except for some specified provisions of the indenture, the holders of
at least a majority in principal amount of the outstanding debt securities of
any series may on behalf of the holders of all debt securities of that series
waive our compliance with provisions of the indenture. The holders of a majority
in principal amount of the outstanding debt securities of any series may on
behalf of the holders of all the debt securities of that series waive any past
default under the indenture with respect to that series and its consequences,
except a default in the payment of the principal, premium or any interest with
respect to any debt security of that series; provided, however, that the holders
of a majority in principal amount of the outstanding debt securities of any
series may rescind an acceleration and its consequences, including any related
payment default that resulted from the acceleration.


                                       22


         Defeasance of Debt Securities and Certain Covenants in Certain
Circumstances Legal Defeasance. The indenture provides that, unless the terms of
the applicable series of debt securities provide otherwise, we may be discharged
from any and all obligations under the debt securities of any series (except for
some obligations to register the transfer or exchange of debt securities of the
series, to replace stolen, lost or mutilated debt securities of the series, and
to maintain paying agencies and certain provisions relating to the treatment of
funds held by paying agents). We will be discharged when we deposit with the
trustee, in trust, money and/or U.S. government obligations or, in the case of
debt securities denominated in a single currency other than U.S. dollars,
foreign government obligations, that, through the payment of interest and
principal in accordance with their terms, will provide money in an amount
sufficient in the opinion of a nationally recognized firm of independent public
accountants to pay and discharge each installment of principal, premium and
interest, and any mandatory sinking fund payments for the debt securities of
that series on the stated maturity in accordance with the terms of the indenture
and those debt securities.

         We will be discharged only if, among other things, we have delivered to
the trustee an officers' certificate and an opinion of counsel stating that we
have received from the United States Internal Revenue Service, or that the
United States Internal Revenue Service has published, a ruling or, since the
date of execution of the indenture, there has been a change in the applicable
United States federal income tax law, in either case to the effect that, holders
of the debt securities of the series from which we wish to be discharged will:

         -        not recognize income, gain or loss for United States federal
                  income tax purposes as a result of the deposit, defeasance and
                  discharge; and

         -        will be subject to United States federal income tax on the
                  same amount and in the same manner and at the same times as
                  would have been the case if the deposit, defeasance and
                  discharge had not occurred.

         Defeasance of Covenants. The indenture provides that, unless otherwise
provided by the terms of the applicable series of debt securities, upon
compliance with specified conditions we may omit to comply with the restrictive
covenants contained in Sections 4.2, 4.3, 4.4, 4.5, 4.6 and 5.1 of the
indenture, as well as any additional covenants contained in a supplement to the
indenture, a resolution of the Board of Directors or an officers' certificate
delivered pursuant to the indenture.

         The conditions include:

         -        our depositing with the trustee money and/or U.S. government
                  obligations or, in the case of debt securities denominated in
                  a single currency other than U.S. dollars, foreign government
                  obligations, that, through the payment of interest and
                  principal in accordance with their terms, will provide money
                  in an amount sufficient in the opinion of a nationally
                  recognized firm of independent public accountants to pay
                  principal, premium and interest, and any mandatory sinking
                  fund payments or the debt securities of that series on the
                  stated maturity in accordance with the terms of the indenture
                  and those debt securities; and

         -        our delivering to the trustee an opinion of counsel to the
                  effect that the holders of the debt securities of that series
                  will not recognize income, gain or loss for United States
                  federal income tax purposes as a result of the deposit and
                  related covenant defeasance and will be subject to United
                  States federal income tax in the same amount and in the same
                  manner and at the same times as would have been the case if
                  the deposit and related covenant defeasance had not occurred.


                                       23


         Covenant Defeasance and Events of Default. In the event we exercise our
option not to comply with some covenants of the indenture with respect to any
series of debt securities and the debt securities of that series are declared
due and payable because of the occurrence of any event of default, the amount of
money and/or U.S. government obligations or foreign government obligations we
have deposited with the trustee will be sufficient to pay amounts due on the
debt securities of that series at the time of their stated maturity but may not
be sufficient to pay amounts due on the debt securities of that series at the
time of the acceleration resulting from the event of default. However, we will
remain liable for those payments.

         "Foreign government obligations" means for the debt securities of any
series that are denominated in a currency other than U.S. dollars:

         -        direct obligations of the government that issued or caused to
                  be issued the currency in question for the payment of which
                  obligations its full faith and credit is pledged, which are
                  not callable or redeemable at the option of the issuer
                  thereof; or

         -        obligations of a person controlled or supervised by or acting
                  as an agency or instrumentality of that government the timely
                  payment of which is unconditionally guaranteed as a full faith
                  and credit obligation by that government, which are not
                  callable or redeemable at the option of the issuer thereof.

GOVERNING LAW

         The indenture and the debt securities will be governed by, and
construed under the internal laws of the State of Florida.


                                       24


                          DESCRIPTION OF CAPITAL STOCK

DESCRIPTION OF COMMON STOCK

         We have the authority to issue 437,500,000 shares of common stock, par
value $0.10 per share. The holders of common stock are entitled to one vote per
share on all matters submitted to a vote of the shareholders. The holders of
common stock have equal, ratable rights to dividends from funds legally
available therefor, when, as and if declared by the Board of Directors, and are
entitled to share ratably in all of the assets available for distribution to
holders of common stock upon the liquidation, dissolution or winding-up of our
affairs. Holders of common stock do not have preemptive, subscription or
conversion rights. There are no redemption or sinking fund provisions in our
Articles of Incorporation. The outstanding shares of common stock are fully paid
and nonassessable. Our Articles of Incorporation do not provide for cumulative
voting by shareholders. Our Common Stock is listed on the American Stock
Exchange under the trading symbol "IVX" and on the London Stock Exchange under
the symbol "IVX.L."

DESCRIPTION OF COMMON STOCK PURCHASE RIGHTS

         On December 19, 1997, our Board of Directors declared a dividend of one
common stock Purchase Right (the "Right(s)") for each outstanding share of
common stock. The dividend was payable as of December 29, 1997 to shareholders
of record on that date. Each Right entitles the registered holder to purchase
from us .9375 of a share of common stock at a price of $12.00 per .9375 of a
share (the "Exercise Price"), subject to certain adjustments. The description
and terms of the Rights are set forth in that certain Rights Agreement (the
"Rights Agreement") between us and the rights agent named therein. The Rights
are not exercisable and are not certificated until the Distribution Date (as
defined below). Until that time the Rights will automatically trade with the
common stock. The Rights will expire at the close of business on December 18,
2007, unless earlier redeemed by us. The number of shares of common stock
issuable upon exercise of the Rights is subject to certain adjustments from time
to time in the event of a stock dividend on, or a subdivision or combination of,
the common stock. The Exercise Price for the Rights is subject to adjustment in
the event of extraordinary distributions of cash or other property to holders of
common stock. Until a Right is exercised, the holder of a Right will have no
rights as a shareholder, including, without limitation, the right to vote or to
receive dividends.

         Distribution Date

         Unless earlier redeemed by our Board of Directors, the Rights become
exercisable upon the close of business on the Distribution Date which is the
earlier of (1) the tenth day following a public announcement that a person or
group of affiliated or associated persons, with certain exceptions, has acquired
beneficial ownership of 15% or more of our outstanding voting stock (an
"Acquiring Person") and (2) the tenth business day (or such later date as may be
determined by our Board of Directors) after the date of the commencement or
announcement of a person's or group's intention to commence a tender or exchange
offer the consummation of which would result in the ownership of 15% or more of
our outstanding voting stock.

         Effect of Triggering Event

         Unless the Rights are earlier redeemed, in the event that, after the
time that a person becomes an Acquiring Person, we were to be acquired in a
merger or other business combination (in which any shares of common stock are
changed into or exchanged for other securities or assets) or more than 50% of
our subsidiaries' (taken as a whole) assets or earning power were to be sold or
transferred in one or a series of related transactions, the Rights Agreement
provides that proper provision will be made so that each holder of record of a
Right will from and after such date have the right to receive, upon payment of
the Exercise Price, that number of shares of common stock of the acquiring
company having a market value at the time of such transaction equal to two times
the Exercise Price. In addition, unless the Rights are earlier redeemed, if a
person or group (with certain exceptions) becomes the beneficial owner of 15% or
more of our voting stock, the Rights Agreement provides that proper provision
will be made so that each holder


                                       25


of record of a Right, other than the Acquiring Person (whose Rights will
thereupon become null and void), will thereafter have the right to receive, upon
payment of the Exercise Price, that number of shares of common stock having a
market value at the time of the transaction equal to two times the Exercise
Price. The Rights Agreement also grants our Board of Directors the option, after
any person or group acquires beneficial ownership of 15% or more of the voting
stock but before there has been a 50% acquisition, to exchange one share of
common stock for each then valid Right (which would exclude Rights held by the
Acquiring Person that have become void).

         Redemption

         At any time on or prior to the close of business on the tenth day after
the time that a person has become an Acquiring Person (or such later date as a
majority of our Board of Directors may determine), we may redeem the Rights in
whole, but not in part, at a price of $.01 per Right (the "Redemption Price").
Immediately upon the effective time of the action of our Board of Directors
authorizing redemption of the Rights, the right to exercise the Rights will
terminate and the only right of the holders of the Rights will be to receive the
Redemption Price.

         Amendment

         For as long as the Rights are then redeemable, we may, except with
respect to the Redemption Price or date of expiration of the Rights, amend the
Rights in any manner, including an amendment to extend the time period in which
the Rights may be redeemed. At any time when the Rights are not then redeemable,
we may amend the Rights in any manner that does not materially adversely affect
the interests of holders of the Rights as such.

         Certain Effects of the Rights

         The Rights have certain anti-takeover effects. The Rights will cause
substantial dilution to a person or group who attempts to acquire us on terms
not approved by our Board of Directors. The Rights should not interfere with any
merger or other business combination approved by our Board of Directors because
we may redeem them at $.01 per Right at any time until the close of business on
the tenth day (or such later date as described above) after a person or group
has obtained beneficial ownership of 15% or more of our voting stock.


                                       26


               MATERIAL ARTICLE, BY-LAW AND FLORIDA LAW PROVISIONS

         We are subject to several anti-takeover provisions under Florida law.
We are subject to the "affiliated transactions" and "control-share acquisition"
provisions of the Florida Business Corporation Act. These provisions require,
subject to limited exceptions, that before we may consummate any "affiliated
transaction," we must obtain the approval of:

         -        the holders of two-thirds of our voting shares other than
                  those beneficially owned by an "interested shareholder;" or

         -        a majority of our disinterested directors.

         Additionally, under Florida law voting rights are generally conferred
on "control shares" acquired in specified control share acquisitions only as
permitted by a resolution that our shareholders approve, excluding holders of
shares defined as "interested shares."

         Florida law presently limits the personal liability of a corporate
director for monetary damages, except where the director:

         -        breaches his or her fiduciary duties; and

         -        the breach constitutes or includes certain unlawful
                  distributions or certain other reckless, wanton or willful
                  acts or misconduct.

         Our bylaws include an advance notice provision under which any
shareholder wishing to make nominations for election to our board of directors
at a meeting of the shareholders or to bring business before an annual meeting
of our shareholders must give written notice to our corporate secretary, subject
to some exceptions, not less than 60 days and not more than 90 days prior to the
date of the meeting.


                                       27


                              PLAN OF DISTRIBUTION

         We may sell the securities subject to this prospectus in or outside the
United States through underwriters or dealers, directly to one or more
purchasers, or through agents. The prospectus supplement with respect to the
securities we are offering will describe the specific terms of our offering,
including:

         -        the name or names of any underwriters, dealers, or agents;

         -        the purchase price of the securities;

         -        the proceeds to us from the offering;

         -        any delayed delivery arrangements;

         -        any underwriting discounts and other items constituting
                  underwriters' compensation;

         -        the initial public offering price;

         -        any discounts or concessions that dealers may allow or reallow
                  or pay; and

         -        any securities exchanges on which we may have listed the
                  securities we are offering.

         If we use underwriters in the sale, then the underwriters will acquire
the securities for their own account and may resell them from time to time in
one or more transactions, including negotiated transactions, at a fixed public
offering price or at varying prices the underwriters determine at the time of
sale. We may offer the securities to the public either through underwriting
syndicates represented by one or more managing underwriters or directly by one
or more firms acting as underwriters. We will name the underwriter or
underwriters for a particular underwritten offering of securities in the
prospectus supplement relating to that offering. If we use an underwriting
syndicate, then we will name the managing underwriter or underwriters on the
cover of the prospectus supplement. Unless we state otherwise in the prospectus
supplement, the obligations of the underwriters or agents to purchase the
offered securities will be subject to conditions precedent and the underwriters
will be obligated to purchase all the securities if they purchase any of them.
We may change the initial public offering price and any discounts or concessions
allowed or reallowed or paid to dealers from time to time.

         If we or the underwriters use dealers in the sale of the securities for
which we are delivering this prospectus, then we will sell those securities to
the dealers as principals. The dealers may then resell the securities to the
public at varying prices that the dealers will determine at the time of their
resale. We will disclose the names of the dealers and the terms of the
transaction in the prospectus supplement.

         We may sell the securities directly or through agents from time to time
at fixed prices that we may change or at varying prices that we will determine
at the time of sale. We will name any agent involved in the offer or sale of the
securities for which we are delivering this prospectus. We will also disclose
any commissions that we will pay to our agents in the prospectus supplement.
Unless we indicate otherwise in the prospectus supplement, our agents will be
acting on a best efforts basis for the period of its appointment.

         We may issue the securities in settlement of derivative securities,
including put options that we issue from time to time to various institutional
investors. Generally, under the terms of the agreements relating to the put
options, if the institutional investor exercises the put option we may elect to
settle the put option by issuing to the institutional investor shares of our
common stock with an aggregate value equal to the difference between (1) the
market price (as defined in the put option) of our common stock and (2) the
exercise price of the put option multiplied by the number of shares covered by
such put option (the "settlement value"). If the shares received by the
institutional investor are sold within 10 business days and the net proceeds are
less than the settlement value, we are obligated to pay the difference in either
cash or additional common shares which will be sold pursuant to this
registration statement; conversely, if the net proceeds are more than the
settlement value, we will


                                       28


receive the difference in a cash refund. We will describe in a prospectus
supplement the terms of any derivative security, including put options that we
have issued, the amount of shares issued in settlement of any such derivative
security, the name of the institutional investors and other terms of the
transaction.

         In connection with the sale of the securities, we or the purchasers of
the securities may pay underwriters, dealers or agents compensation in the form
of discounts, concessions or commissions. Underwriters, agents and dealers
participating in the distribution of the securities may be underwriters, and any
discounts or commissions that they receive from us and any profit they realize
on their resale of the securities may be underwriting discounts or commissions
under the Securities Act.

         We may sell the securities directly to institutional investors or
others, who may be underwriters within the meaning of the Securities Act with
respect to any resale of those securities. We will describe the terms of those
sales in the prospectus supplement.

         If we indicate in the prospectus supplement, we will authorize our
agents, underwriters or the dealers to solicit offers from institutions to
purchase the securities at the public offering price that we will disclose in
the prospectus supplement under delayed delivery contracts. A delayed delivery
contract provides for the investor's payment and our delivery of the purchased
securities on a specified date in the future. We expect that these contracts
will be subject only to the conditions that we describe in the prospectus
supplement. The prospectus supplement will describe the commission that we pay
our agents to solicit those contracts.

         Our agreements with our agents, dealers and underwriters may require us
to indemnify them against a number of civil liabilities, including liabilities
under the Securities Act, or to grant them contribution for payments that they
may be required to make as a result of those liabilities. Our agents, dealers
and underwriters and their affiliates may be customers of, engage in
transactions with, or perform services for us in the ordinary course of their
business.

         Some or all of the securities that we may issue may be new issues of
securities with no established trading market. Any underwriters to whom we sell
securities for a public offering may make a market in those securities, but we
can not obligate them to do so and even if they do they may discontinue any
market making at any time without notice. We can not assure you that a trading
market will develop for any of the securities that we may offer or if any market
does develop how liquid that market will be.

         In order to facilitate the offering of our securities, any underwriters
or agents, as the case may be, involved in the offering of our securities may
engage in transactions that stabilize, maintain or otherwise affect the price of
our securities or any other securities the prices of which we may use to
determine payments on our securities. Specifically, the underwriters or agents,
as the case may be, may over allot in connection with the offering, creating a
short position in the securities for their own account. In addition, to cover
over allotments or to stabilize the price of our securities or any other
securities, the underwriters or agents, as the case may be, may bid for, and
purchase, our securities or any other securities in the open market. Finally, in
any offering of our securities through a syndicate of underwriters, the
underwriting syndicate may reclaim selling concessions allowed to an underwriter
or a dealer for distributing the securities in the offering if the syndicate

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS

         Section 607.0831 of the Florida Business Corporation Act (the "Florida
Act") provides that a director is not personally liable for monetary damages to
the corporation or any person for any statement, vote, decision or failure to
act regarding corporate management or policy, by a director, unless: (a) the
director breached or failed to perform his duties as a director; and (b) the
director's breach of, or failure to perform, those duties constitutes: (1) a
violation of criminal law unless the director had reasonable cause to believe
his conduct was lawful or had no reasonable cause to believe his conduct was
unlawful; (2) a transaction from which the director derived an improper personal
benefit, either directly or indirectly; (3) a circumstance under which the
director is liable for an improper distribution; (4) in a proceeding by, or in
the right of the corporation to procure a judgment in its favor or by or in the
right of a shareholder, conscious disregard for the best interest of the
corporation, or willful misconduct or (5) in a proceeding by or in the right of
someone other than the corporation or a shareholder, recklessness or an act or
omission which was committed in bad faith or with malicious purpose or in a
manner exhibiting wanton or willful disregard of human rights, safety or
property.

         Section 607.0850 of the Florida Act provides that a corporation shall
have the power to indemnify any person who was or is a party to any proceeding
(other than an action by, or in the right of, the corporation), by reason of the
fact that he is or was a director, officer or employee or agent of the
corporation, against liability incurred in connection with such proceeding if he
acted in good faith and in a manner he reasonably believed to be in, or not
opposed to, the best interest of the corporation and, with respect to any
criminal action or proceeding, had no reasonable cause to believe his conduct
was unlawful. Section 607.0850 also provides that a corporation shall have the
power to indemnify any person, who was or is a party to any proceeding by, or in
the right of, the corporation to procure a judgment in its favor by reason of
the fact that he is or was a director, officer, employee or agent of the
corporation, against expenses and amounts paid in settlement not exceeding, in
the judgment of the board of directors, the estimated expense of litigating the
proceeding to conclusion, actually and reasonably incurred in connection with
the defense or settlement of such proceeding, including any appeal thereof.


                                      II-1


         Section 607.0850 further provides that such indemnification shall be
authorized if such person acted in good faith and in a manner he reasonably
believed to be in, or not opposed to, the best interests of the corporation,
except that no indemnification shall be made under this provision in respect of
any claim, issue, or matter as to which such person shall have been adjudged to
be liable unless, and only to the extent that, the court in which such
proceeding was brought, or any other court of competent jurisdiction, shall
determine upon application that, despite the adjudication of liability, but in
view of all circumstances of the case, such person is fairly and reasonably
entitled to indemnity for such expenses which court shall deem proper. Section
607.0850 further provides that to the extent that a director, officer, employee
or agent has been successful on the merits or otherwise in defense of any of the
foregoing proceedings, or in defense of any claim, issue or matter therein, he
shall be indemnified against expenses actually and reasonably incurred by him in
connection therewith. Under Section 607.0850, any indemnification under the
foregoing provisions, unless pursuant to a determination by a court, shall be
made by the corporation only as authorized in the specific case upon a
determination that the indemnification of the director, officer, employee or
agent is proper under the circumstances because he has met the applicable
standard of conduct. Notwithstanding the failure of a corporation to provide
such indemnification, and despite any contrary determination by the corporation
in a specific case, a director, officer, employee or agent of the corporation
who is or was a party to a proceeding may apply for indemnification to the
appropriate court and such court may order indemnification if it determines that
such person is entitled to indemnification under the applicable standard.

         Section 607.0850 also provides that a corporation shall have the power
to purchase and maintain insurance on behalf of any person who is or was a
director, officer, employee or agent of the corporation against any liability
asserted against him and incurred by him in any such capacity or arising out of
his status as such, whether or not the corporation would have the power to
indemnify him against such liability under the provisions of Section 607.0850.

         The Registrant's bylaws provide that it shall indemnify its officers
and directors and former officers and directors to the full extent permitted by
law.

         The Registrant has entered into indemnification agreements with each of
its officers and directors. The indemnification agreements generally provide
that the Registrant will pay certain amounts incurred by an officer or director
in connection with any civil or criminal action or proceeding and specifically
including actions by or in the name of the Registrant (derivative suits) where
the individual's involvement is by reason of the fact that he was or is an
officer or director. Under the indemnification agreements, an officer or
director will not receive indemnification if such person is found not to have
acted in good faith and in a manner he reasonably believed to be in or not
opposed to the best interests of the Registrant. The agreements provide a number
of procedures and presumptions used to determined the officer's or director's
right to indemnification and include a requirement that in order to receive an
advance of expenses, the officer or director must submit an undertaking to repay
any expenses advanced on his behalf that are later determined he was not
entitled to receive.

         The Registrant's directors and officers are covered by insurance
policies indemnifying them against certain liabilities, including liabilities
under the federal securities laws (other than liability under Section 16(b) of
the Exchange Act), which might be incurred by them in such capacities.

ITEM 17. UNDERTAKINGS

(a)      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


                                      II-3


                           information set forth in the registration statement.
                           Notwithstanding the foregoing, any increase or
                           decrease in volume of securities offered (if the
                           total dollar value of securities offered would not
                           exceed that which was registered) and any deviation
                           from the low or high end of the estimated maximum
                           offering range may be reflected in the form of
                           prospectus filed with the Securities and Exchange
                           Commission pursuant to Rule 424(b) if, in the
                           aggregate, the changes in volume and price represent
                           no more than a 20% change in the maximum aggregate
                           offering price set forth in the "Calculation of
                           Registration Fee" table in the effective registration
                           statement;

                  (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;

                  provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do
                  not apply if the information required to be included in a
                  post-effective amendment by those paragraphs is contained in
                  periodic reports filed with or furnished to the Securities and
                  Exchange Commission by the registrant pursuant to Section 13
                  or Section 15(d) of the Securities Exchange Act of 1934 that
                  are incorporated by reference 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.

(b)      The undersigned Registrant hereby undertakes that, for purposes of
         determining any liability under the Securities Act of 1933, each filing
         of the Registrant's annual report pursuant to section 13(a) or section
         15(d) of the Securities Exchange Act of 1934 (and, where applicable,
         each filing of an employee benefit plan's annual report pursuant to
         section 15(d) of the Securities Exchange Act of 1934) that is
         incorporated by reference in the registration statement 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.

(c)      Insofar as indemnification for liabilities arising under the Securities
         Act of 1933 may be permitted to directors, officers and controlling
         persons of the Registrant pursuant to the foregoing provisions, or
         otherwise, the Registrant has been advised that in the opinion of the
         Securities and Exchange Commission such indemnification is against
         public policy as expressed in the Securities Act of 1933 and is,
         therefore, unenforceable. In the event that a claim for indemnification
         against such liabilities (other than the payment by the Registrant of
         expenses incurred or paid by a director, officer or controlling person
         of the Registrant in the successful defense of any action, suit or
         proceeding) is asserted by such director, officer or controlling person
         in connection with the securities being registered, the Registrant
         will, unless in the opinion of its counsel the matter has been settled
         by controlling precedent, submit to a court of appropriate jurisdiction
         the question whether such indemnification by it is against public
         policy as expressed in the Securities Act of 1933 and will be governed
         by the final adjudication of such issue.


                                      II-4


(d)      The undersigned Registrant hereby undertakes to file an application for
         the purpose of determining the eligibility of the Trustee to act under
         subsection (a) of 310 of the Trust Indenture Act in accordance with the
         rules and regulations prescribed by the Commission under Section
         305(b)(2) of the Trust Indenture Act.

         Pursuant to the requirements of the Securities Act of 1933, the
registrant certifies that it has reasonable grounds to believe that it meets all
of the requirements for filing on Form S-3 and has duly caused this Post
