supplement summary
This summary highlights information contained elsewhere in
this prospectus supplement and the accompanying prospectus and
in the documents we incorporate by reference. This summary does
not contain all of the information that you should consider
before deciding to invest in our common stock. You should read
this entire prospectus supplement and the accompanying

section contained in this prospectus supplement and our

Idenix
Pharmaceuticals, Inc.
Our
Business
Idenix Pharmaceuticals, Inc. is a biopharmaceutical company
engaged in the discovery and development of drugs for the
treatment of human viral diseases with operations in the United
States and Europe.
Currently, our primary research and development focus is on the
treatment of patients with hepatitis C virus, or HCV. HCV
is a leading cause of liver disease. According to the World
Health Organization, HCV is responsible for 50% to 76% of all
liver cancer cases worldwide and two-thirds of all liver
transplants in the developed world. The World Health
Organization also has estimated that approximately
180 million people worldwide are chronically infected with
HCV and an additional three to four million people are infected
each year. We believe that large market opportunities exist for
new treatments of HCV because current treatments, which include
pegylated interferon in combination with ribavirin, or
Peg-IFN/RBV, are poorly tolerated and only effective in about
half of patients infected with HCV genotype 1, the most common
strain of the virus.
Our strategic goal is to develop all oral combinations of
direct-acting antiviral, or DAA, drug candidates that should
eliminate the need for interferon
and/or
ribavirin with the current treatment for HCV. Our objective is
to develop low dose, once- or twice-daily agents with broad
genotypic activity that have low potential for drug-drug
interaction, high tolerability and are designed for use in
multiple combination regimens. We will seek to build a
combination development strategy, both internally and with
partners, to advance the future of HCV treatments.
Our HCV discovery program is focused on multiple classes of
drugs, which include nucleoside/nucleotide polymerase inhibitors
and NS5A inhibitors:
Combination DAA Strategy.
In July 2010, we conducted
a
14-day
phase I drug-drug interaction study with two of our HCV drug
candidates, IDX184 and IDX320, in 20 healthy volunteers. In
September 2010, the U.S. Food and Drug Administration, or
FDA, placed these drug candidates on clinical hold due to three
serious adverse events of elevated liver function tests that
were detected during post drug exposure safety visits following
the
14-day
drug-drug interaction study. We believe the hepatotoxicity
observed in this drug-drug interaction was caused by IDX320 and
therefore, we discontinued the clinical development of IDX320.
In February 2011, the full clinical hold on IDX184 was removed.
The program was placed on partial clinical hold, which allowed
us to initiate a phase IIb
S-1
12-week
clinical trial of IDX184 in combination with Peg-IFN/RBV
described in more detail below.
Nucleoside/Nucleotide Polymerase Inhibitors.
The
most advanced of our development programs is IDX184, a novel
liver-targeted nucleotide prodrug candidate. In the third
quarter of 2010, we completed a
14-day
dose-ranging phase IIa clinical trial evaluating IDX184 in
combination with Peg-IFN/RBV in treatment-naive HCV genotype
1-infected patients. In this clinical trial IDX184 was well
tolerated and showed potent HCV antiviral activity. As discussed
above, in February 2011, the FDA removed the full clinical hold
on IDX184, originally imposed in September 2010, and placed the
program on partial clinical hold, which allowed us to initiate a
phase IIb 12-week clinical trial of IDX184 in combination with
Peg-IFN/RBV.
In July 2011, we initiated enrollment of 100 HCV-infected
patients into the phase IIb clinical trial of IDX184. This
double-blind phase IIb clinical trial will include a total of
100 treatment naive HCV genotype 1 infected patients. Patients
will be enrolled in one of two arms. One arm of 50 patients will
receive 50 mg of IDX184 once per day in combination with
Peg-IFN/RBV and the other 50 patients will receive
100 mg of IDX184 once per day in combination with
Peg-IFN/RBV. Patients in this clinical trial will receive IDX184
for 12 weeks. The endpoints in the trial include drug
safety and viral load endpoints at four and 12 weeks and
sustained virologic response determination at 12 and
24 weeks post treatment with Peg-IFN/RBV.
We will provide an interim analysis of our first 30 patients
following 28 days of treatment to a data safety monitoring
board, or DSMB, and to the FDA. After the initial
30 patients are enrolled in the trial we will not dose any
additional patients until after the interim analysis of the
28-day data on the first 30 patients has been reviewed by the
DSMB. We initiated dosing of the first 20 patients, and we
are currently enrolling the remaining ten patients. There have
been no safety signals to date. Based on the current rate of
enrollment, we expect to complete one month dosing of the first
30 patients in December 2011, and anticipate releasing
interim one month safety and antiviral activity data for the
first 30 patients from the phase IIb trial early in the
first quarter of 2012. An additional interim analysis will be
provided to the DSMB after 60 patients have been on treatment
for 28 days.
NS5A Inhibitors.
We selected IDX719 as our lead NS5A
candidate. In preclinical studies, IDX719 has shown potent and
broad genotypic activity. We anticipate submitting an
investigational new drug, or IND, or a clinical trial
application, or CTA, by year end 2011 and beginning clinical
studies in early 2012.
In February 2009, we licensed our drug candidates from the class
of compounds known as non-nucleoside reverse transcriptase, or
NNRTI, on a worldwide basis to GlaxoSmithKline for the treatment
of human diseases, including human immunodeficiency virus
type-1, or HIV, and acquired immune deficiency syndrome, or
AIDS. We refer to this agreement as the GSK license
agreement. In October 2009, GlaxoSmithKline assigned the
GSK license agreement to its affiliate, ViiV Healthcare Company,
which we refer to collectively with GlaxoSmithKline as
GSK. The compounds covered by the GSK license
agreement include GSK2248761, or 761, which we formerly
referred to as IDX899. Under the GSK license agreement, in 2010,
we received a $6.5 million milestone payment for the
achievement of a preclinical operational milestone and a
$20.0 million milestone payment for the initiation of a
phase IIb clinical study related to the development of
761. Under the GSK license agreement, we could potentially
S-2
receive up to $390.0 million in additional milestone
payments as well as double-digit tiered royalties on worldwide
product sales. In February 2011, GSK informed us that the FDA
placed 761 on clinical hold. GSK has full responsibility
for the development of 761, including any regulatory
interaction.
In May 2003, we entered into a collaboration with Novartis
Pharma AG, or Novartis, relating to the worldwide development
and commercialization of our drug candidates. As part of this
collaboration, Novartis has an option to license any of our
development-stage drug candidates after demonstration of
activity and safety in a
proof-of-concept
clinical trial so long as Novartis maintains at least 30%
ownership of our common stock. In October 2009, Novartis waived
its option to license IDX184. As a result, we retain the
worldwide rights to develop, manufacture, commercialize and
license IDX184. We may seek a partner who will assist in
maximizing the value of IDX184 through its further development
and commercialization. Prior to this offering, Novartis owned
approximately 35% of our outstanding common stock. After giving
effect to our issuance and sale of shares of common stock in
this offering, Novartis will own
approximately % of our outstanding
common stock, or % if the
underwriter exercises its over-allotment option in full.

S-4
Risk
factors
Investing in our common stock involves significant risks. In
addition to the Risk Factors described below and the other
information included or incorporated by reference in this
prospectus supplement and the accompanying prospectus, you
should carefully consider the risks described in Part I.
Item 1A.Risk Factors in our Annual Report
on
Form 10-K
for the fiscal year ended December 31, 2010 and
Part II. Item 1A.Risk Factors in our
Quarterly Report on
Form 10-Q
for the quarter ended September 30, 2011, both of which we
have filed with the Securities and Exchange Commission, or the
SEC, and which are incorporated by reference herein, before
making an investment decision. We caution you that the risks and
uncertainties we have described, among others, could cause our
actual results to differ materially from those expressed in
forward-looking statements made by us or on our behalf in
filings with the SEC, press releases, communications with
investors and oral statements. Any or all such forward-looking
statements we make may turn out to be wrong. They can be
affected by inaccurate assumptions we might make or by known or
unknown risks and uncertainties. Consequently, no results
expressed by our forward-looking statements can be guaranteed.
We undertake no obligation to update any forward-looking
statements, whether as a result of new information, future
events or otherwise. You are advised, however, to consult any
further disclosure we make in our reports filed with the SEC.
Risks Relating to
this Offering
We will need
additional capital to fund our operations, including the
development, manufacture and potential commercialization of
IDX184 and our other drug candidates. If we do not have or
cannot raise additional capital when needed, we will be unable
to develop and ultimately commercialize our drug candidates
successfully.
We believe that our current cash and cash equivalents balance,
the anticipated royalty payments associated with product sales
of
Tyzeka
®
/Sebivo
®
and the net proceeds we receive from this offering will be
sufficient to satisfy our cash needs for at least the next
12 months following this offering. Our drug development
programs and the potential commercialization of our drug
candidates will require substantial additional cash to fund
expenses that we will incur in connection with the development
of IDX184 and other preclinical studies and clinical trials of
other product candidates, regulatory review and future
manufacturing and sales and marketing efforts. If we are unable
to obtain adequate financing on a timely basis, we could be
required to delay, reduce or eliminate one or more of our drug
development programs or to enter into new collaborative,
strategic alliances or licensing arrangements that may not be
favorable to us. More generally, if we are unable to obtain
adequate funding, we may be required to scale back, suspend or
terminate our business operations.
Investors in
this offering will pay a much higher price than the book value
of our stock.
If you purchase common stock in this offering, you will incur an
immediate and substantial dilution in net tangible book value of
$ per share, after giving effect
to the sale by us of shares in this offering at the public
offering price of $ per share. In
the past, we have issued options to acquire common stock at
prices significantly below this offering price. To the extent
these outstanding options are ultimately exercised, you will
incur additional dilution.
S-5
Our management
will have broad discretion over the use of the net proceeds from
this offering, and you may not agree with how we use the
proceeds and the proceeds may not be invested
successfully.
Our management will have broad discretion as to the use of the
net proceeds from any offering by us and could use them for
purposes other than those contemplated at the time of this
offering. Accordingly, you may be relying on the judgment of our
management with regard to the use of these net proceeds, and you
will not have the opportunity, as part of your investment
decision, to assess whether the proceeds are being used
appropriately. It is possible that the proceeds will be invested
in a way that does not yield a favorable, or any, return for
Idenix.
S-6
Special note
regarding forward-looking statements
This prospectus supplement, the accompanying prospectus and the
documents incorporated by reference herein and therein contain
forward-looking statements within the meaning of
Section 27A of the Securities Act of 1933, as amended, or
the Securities Act, and Section 21E of the Securities
Exchange Act of 1934, as amended, or the Exchange Act,
concerning our business, operations and financial condition,
including statements with respect to how long our anticipated
cash resources will fund our expected operations, the expected
timing and results of completion of phases of development of our
drug candidates, the safety, efficacy and potential benefits of
our drug candidates, expectations with respect to development
and commercialization of telbivudine and our other drug
candidates, expectations with respect to a licensing arrangement
with a third-party, the timing and results of the submission,
acceptance and approval of regulatory filings, the scope of
patent protection with respect to these drug candidates and
information with respect to the other plans and strategies for
our business. All statements other than statements of historical
facts included or incorporated by reference in this prospectus
supplement and the accompanying prospectus may be deemed as
forward-looking statements. Without limiting the foregoing,
expect, anticipate, intend,
may, plan, believe,
seek, estimate, projects,
will, would and similar expressions or
express or implied discussions regarding potential new products
or regarding future revenues from such products, potential
future expenditures or liabilities or any discussions of
strategy, plans or intentions are also intended to identify
forward-looking statements, although not all forward-looking
statements contain these identifying words. Because these
forward-looking statements involve known and unknown risks and
uncertainties, actual results, performance or achievements could
differ materially from those expressed or implied by these
forward-looking statements for a number of important reasons,
including those discussed under Risk Factors in this
prospectus supplement, under Part I.
Item 1A.Risk Factors and Part II.
Item 7.Managements Discussion and
Analysis of Financial Condition and Results of Operations
in our Annual Report on
Form 10-K
for the fiscal year ended December 31, 2010 and
Part I. Item 2.Managements
Discussion and Analysis of Financial Condition and Results of
Operations and Part II. Item 1A.Risk
Factors in our Quarterly Report on
Form 10-Q
for the quarter ended September 30, 2011, both of which we
have filed with the SEC and which are incorporated by reference
herein. In particular, managements expectations could be
affected by, among other things, uncertainties involved in the
development of new pharmaceutical products, including unexpected
clinical trial results; unexpected regulatory actions or delays,
including with respect to FDA review of IDX184, or government
regulation generally; our ability to obtain or maintain patent
or other proprietary intellectual property protection;
competition in general; government, industry and general public
pricing pressures; and uncertainties regarding necessary levels
of expenditures in the future. There can be no guarantee that
development of any drug candidates described will succeed or
that any new products will obtain necessary regulatory approvals
required for commercialization or otherwise be brought to
market. Similarly, there can be no guarantee that we or one or
more of our current or future products, if any, will achieve any
particular level of revenue.
You should read these forward-looking statements carefully
because they discuss our expectations regarding our future
performance, future operating results or future financial
condition, or state other forward-looking
information. You should be aware that the occurrence of any of
the events described under Risk Factors herein and
in any document incorporated by reference herein and elsewhere
in this prospectus supplement, the accompanying prospectus and
the documents incorporated by reference herein could
substantially harm our business,
S-7
results of operations and financial condition and that upon the
occurrence of any of these events, the price of our common stock
could decline.
We cannot guarantee any future results, levels of activity,
performance or achievements. Should one or more of these risks
or uncertainties materialize, or should underlying assumptions
prove incorrect, actual results may vary materially from those
described in this prospectus supplement, the accompanying
prospectus or the documents incorporated by reference herein as
anticipated, believed, estimated or expected. The
forward-looking statements contained or incorporated by
reference herein represent our expectations as of the date of
such statements (unless another date is indicated) and should
not be relied upon as representing our expectations as of any
other date. While we may elect to update these forward-looking
statements, we specifically disclaim any obligation to do so,
even if our expectations change.
S-8
Use of
proceeds
We estimate that the net proceeds we will receive from this
offering will be approximately
$ million, after deducting
the estimated underwriting discounts and commissions and
estimated offering expenses payable by us. If the underwriter
exercises its over-allotment option in full, we estimate that
the net proceeds to us will be approximately
$ million.
We intend to use the net proceeds from this offering for general
corporate purposes. Although we have not yet identified specific
uses for these proceeds, we currently anticipate using the
proceeds for some or all of the following purposes:
|
|
|
research and development expenditures relating to our
nucleoside/nucleotide and other discovery programs;
|
|
|
working capital;
|
|
|
capital expenditures; and
|
|
|
potential acquisitions of new businesses, technologies or
products that we believe complement or expand our business.
|
We have not determined the amounts we plan to spend on any of
the areas listed above or the timing of these expenditures. As a
result, our management will have broad discretion to allocate
the net proceeds from this offering. We have no current
commitments or agreements with respect to any acquisitions and
may not make any acquisitions. Pending application of the net
proceeds as described above, we intend to invest the net
proceeds of the offering in short-term, investment-grade and
U.S. government securities.
S-9
Dilution
If you purchase our common stock in this offering, your interest
will be diluted to the extent of the difference between the
public offering price per share and the net tangible book value
per share of our common stock after this offering. We calculate
net tangible book value per share by subtracting our total
liabilities from our total tangible assets and dividing the
difference by the number of outstanding shares of our common
stock.
Our net tangible book value at September 30, 2011 was
$(11.3) million, or $(0.12) per share, based on
approximately 96,153,387 million shares of our common stock
then outstanding. After giving effect to the sale
of shares
of common stock by us at the public offering price of
$ per share, less the estimated
underwriting discounts and commissions and estimated offering
expenses payable by us, our net tangible book value at
September 30, 2011 would be
$ million, or
$ per share. This represents an
immediate increase in net tangible book value of
$ per share to existing
stockholders and an immediate dilution of
$ per share to investors in this
offering. The following table illustrates this per share
dilution:

In the discussion and table above, we assume no exercise of
outstanding options. As of September 30, 2011, there were
7,803,512 shares of common stock issuable upon exercise of
outstanding options with a weighted average exercise price of
$6.17 per share. To the extent that any of these
outstanding options are exercised, we grant additional options
or other awards under our stock incentive plan or we issue
additional shares of common stock in the future, there will be
further dilution to new investors. In addition, if outstanding
options are exercised, other than outstanding options granted
under our 1998 equity incentive plan, Novartis could exercise
its right to purchase additional shares of our common stock,
which would further dilute new investors.
S-10

S-13
In connection with this offering, the underwriter may engage in
stabilizing transactions, which involves making bids for,
purchasing and selling shares of common stock in the open market
for the purpose of preventing or retarding a decline in the
market price of the common stock while this offering is in
progress. These stabilizing transactions may include making
short sales of the common stock, which involves the sale by the
underwriter of a greater number of shares of common stock than
they are required to purchase in this offering, and purchasing
shares of common stock on the open market to cover positions
created by short sales. Short sales may be covered
shorts, which are short positions in an amount not greater than
the underwriters over-allotment option referred to above,
or may be naked shorts, which are short positions in
excess of that amount. The underwriter may close out any covered
short position either by exercising its over-allotment option,
in whole or in part, or by purchasing shares in the open market.
In making this determination, the underwriter will consider,
among other things, the price of shares available for purchase
in the open market compared to the price at which the
underwriter may purchase shares through the over-allotment
option. A naked short position is more likely to be created if
the underwriter is concerned that there may be downward pressure
on the price of the common stock in the open market that could
adversely affect investors who purchase in this offering. To the
extent that the underwriter creates a naked short position, it
will purchase shares in the open market to cover the position.
The underwriter has advised us that, pursuant to
Regulation M of the Securities Act of 1933, it may also
engage in other activities that stabilize, maintain or otherwise
affect the price of the common stock, including the imposition
of penalty bids.
These activities may have the effect of raising or maintaining
the market price of the common stock or preventing or retarding
a decline in the market price of the common stock, and, as a
result, the price of the common stock may be higher than the
price that otherwise might exist in the open market. If the
underwriter commences these activities, it may discontinue them
at any time. The underwriter may carry out these transactions on
The Nasdaq Global Market, in the
over-the-counter
market or otherwise.
In addition, in connection with this offering the underwriter
may engage in passive market making transactions in our common
stock on The Nasdaq Global Market prior to the pricing and
completion of this offering. Passive market making consists of
displaying bids on The Nasdaq Global Market no higher than the
bid prices of independent market makers and making purchases at
prices no higher than these independent bids and effected in
response to order flow. Net purchases by a passive market maker
on each day are generally limited to a specified percentage of
the passive market makers average daily trading volume in
the common stock during a specified period and must be
discontinued when such limit is reached. Passive market making
may cause the price of our common stock to be higher than the
price that otherwise would exist in the open market in the
absence of these transactions. If passive market making is
commenced, it may be discontinued at any time.
Other than in the United States, no action has been taken by us

ABOUT
IDENIX PHARMACEUTICALS, INC.
Idenix Pharmaceuticals, Inc. is a biopharmaceutical company
engaged in the discovery and development of drugs for the
treatment of human viral diseases with operations in the United
States and Europe.
Currently, our primary research and development focus is on the
treatment of hepatitis C virus, or HCV. HCV is a leading
cause of liver disease. According to the World Health
Organization, HCV is responsible for 50% to 76% of all liver
cancer cases worldwide and two-thirds of all liver transplants
in the developed world. The World Health Organization also has
estimated that approximately 180 million people worldwide
are chronically infected with HCV and an additional three to
four million people are infected each year. We believe that
large market opportunities exist for new treatments of HCV
because the current treatment with pegylated interferon in
combination with ribavirin, or Peg-IFN/RBV, is poorly tolerated
and only effective in about half of patients infected with HCV
genotype 1, the most common strain of the virus. Our strategic
goal is to develop all oral combinations of direct-acting
antiviral, or DAA, drug candidates that may eliminate the need
for interferon
and/or
ribavirin. Our objective is to develop low dose, once- or
twice-daily agents with broad genotypic activity that have low
potential for drug-drug interactions, high tolerability and are
designed for use in multiple DAA combination regimens. We intend
to build a combination development strategy, both internally and
with third parties, to advance the future of HCV treatment.
Our HCV discovery program is focused on multiple classes of
drugs, which include nucleoside/nucleotide polymerase
inhibitors, protease inhibitors and NS5A inhibitors.
Our
Relationship with Novartis
In May 2003, we entered into a collaboration with Novartis
relating to the worldwide development and commercialization of
our product candidates. As part of this collaboration, Novartis
has an option to license any of our development-stage drug
candidates after demonstration of activity and safety in a
proof-of-concept
clinical trial so long as Novartis maintains at least 30%
ownership of our common stock. Novartis currently owns
approximately 35% of our outstanding common stock.
As part of the development, license and commercialization
agreement between us and Novartis, Novartis has an option to
license any of our development-stage product candidates,
generally 90 days after early demonstration of antiviral
activity and safety in clinical testing. In October 2009,
Novartis waived its option to license IDX184. As a result, we
retain the worldwide rights to develop, manufacture,
commercialize and license IDX184. We may seek a partner who will
assist in maximizing the value of IDX184 through its further
development and commercialization.
Novartis

Pursuant to stock purchase rights held by Novartis, in
connection with any offering by us of our common stock, Novartis
has the right to purchase from us that number of shares of our

our common stock that were transferred to Novartis by Novartis
BioVentures on August 31, 2005. If Novartis exercises this

to cause us to register or participate in a registration by us
under the Securities Act of shares of our common stock held by
such holder if we propose to register any of our common stock.
In addition, pursuant to the amended and restated
stockholders agreement among us, Novartis and other
preference holders, dated as of July 27, 2004 and amended
as of April 6, 2011, or the stockholders agreement,
Novartis and its affiliates will have registration rights, with

with or without cause, at any time, by a vote of the holders of
a majority of the outstanding shares entitled to vote on the

Stockholders
Agreement
Under the terms of the stockholders agreement, we:
|
|
|
|
|
granted Novartis, its affiliates and other preference holders
rights to cause us to register, under the Securities Act, the
shares of common stock owned by such stockholders as described
above under the caption Registration Rights;
|
|
|
|
agreed to use our reasonable best efforts to nominate for
election as a director at least two designees of Novartis for so
long as Novartis and its affiliates own at least 30% of our
voting stock and at least one designee of Novartis for so long
as Novartis and its affiliates own at least 19.4% of our voting
stock; and
|
|
|
|
granted Novartis approval rights over a number of corporate
actions that we or our subsidiaries may take as long as Novartis
and its affiliates continue to own at least 19.4% of our voting
stock.
|
Novartis
Stock Purchase Rights
Novartis has the right to purchase, at par value of $0.001 per
share, such number of shares as is required to maintain its
percentage ownership of our voting stock if we issue shares of
common stock in connection with the acquisition or in-licensing
of technology through the issuance of up to 5% of our common
stock in any
24-month
period. These purchase rights of Novartis remain in effect until
the earlier of the date that Novartis and its affiliates own
less than 19.4% of our voting stock or the date that Novartis
becomes obligated
6
to make contingent payments of $357,000,000 to those holders of
the our stock who sold shares to Novartis on May 8, 2003.
Additionally, if we issue any shares of our capital stock, other
than in certain situations, Novartis has the right to purchase
such number of shares required to maintain its percentage
ownership of our voting stock for the same consideration per
share paid by others acquiring our stock in such transaction.
Directors
Liability
Our restated certificate of incorporation, as amended, contains
provisions permitted under the General Corporation Law of
Delaware relating to the liability of directors. The provisions
provide that our directors will not have personal liability for
monetary damages for any breach of fiduciary duty as a director,
except to the extent that the General Corporation Law of
Delaware prohibits the elimination or limitation of liability of
directors for breaches of fiduciary duty. Further, our restated
certificate of incorporation contains provisions to indemnify
our directors and officers to the fullest extent permitted by
the General Corporation Law of Delaware. We also maintain
directors and officers liability insurance. We
believe that these provisions will assist us in attracting and
retaining qualified individuals to serve as directors.
Effects
of Authorized but Unissued Stock
We have shares of common stock available for future issuance
without stockholder approval, subject to any limitations imposed
by the listing standards of the NASDAQ Global Market and our
existing contractual arrangements with Novartis. We may utilize
these additional shares for a variety of corporate purposes,
including for future public offerings to raise additional
capital or facilitate corporate acquisitions or for payment as a
dividend on our capital stock. Moreover, Novartis current
ownership of approximately 35% of our outstanding common stock,
together with its stock purchase rights and rights under the
Stockholders Agreement, could have the effect of making it
more difficult for a third party to acquire, or could discourage
a third party from seeking to acquire, a controlling interest in
our company by means of a merger, tender offer, proxy contest or
otherwise.
PLAN OF
DISTRIBUTION
We may sell securities:
|
|
|
|
|
through underwriters;
|
|
|
|
through dealers;
|
|
|
|
through agents;
|
|
|
|
directly to purchasers; or
|
|
|
|
through a combination of any of these methods of sale.
|
In addition, we may issue the securities as a dividend or
distribution or in a subscription rights offering to our
existing security holders.
We may directly solicit offers to purchase securities, or agents
may be designated to solicit such offers. We will, in the
prospectus supplement relating to such offering, name any agent
that could be viewed as an underwriter under the Securities Act,
and describe any commissions that we must pay. Any such agent
will be acting on a best efforts basis for the period of its
appointment or, if indicated in the applicable prospectus
supplement, on a firm commitment basis. This prospectus may be
used in connection with any offering of our securities through
any of these methods or other methods described in the
applicable prospectus supplement.
The distribution of the securities may be effected from time to
time in one or more transactions:
|
|
|
|
|
at a fixed price, or prices, which may be changed from time to
time;
|
|
|
|
at market prices prevailing at the time of sale;
|
7
|
|
|
|
|
at prices related to such prevailing market prices; or
|
|
|
|
at negotiated prices.
|
Each prospectus supplement will describe the method of
distribution of the securities and any applicable restrictions.
The prospectus supplement with respect to the securities of a
particular series will describe the terms of the offering of the
securities, including the following:
|
|
|
|
|
the name of the agent or any underwriters;
|
|
|
|
the public offering or purchase price;
|
|
|
|
any discounts and commissions to be allowed or paid to the agent
or underwriters;
|
|
|
|
all other items constituting underwriting compensation;
|
|
|
|
any discounts and commissions to be allowed or paid to
dealers; and
|
|
|
|
any exchanges on which the securities will be listed.
|
If any underwriters or agents are utilized in the sale of the
securities in respect of which this prospectus is delivered, we
will enter into an underwriting agreement or other agreement
with them at the time of sale to them, and we will set forth in
the prospectus supplement relating to such offering the names of
the underwriters or agents and the terms of the related
agreement with them.
If a dealer is utilized in the sale of the securities in respect
of which the prospectus is delivered, we will sell such
securities to the dealer, as principal. The dealer may then
resell such securities to the public at varying prices to be
determined by such dealer at the time of resale.
If we offer securities in a subscription rights offering to our
existing security holders, we may enter into a standby
underwriting agreement with dealers, acting as standby
underwriters. We may pay the standby underwriters a commitment
fee for the securities they commit to purchase on a standby
basis. If we do not enter into a standby underwriting
arrangement, we may retain a dealer-manager to manage a
subscription rights offering for us.
Agents, underwriters, dealers and other persons may be entitled
under agreements which they may enter into with us to
indemnification by us against certain civil liabilities,
including liabilities under the Securities Act, and may be
customers of, engage in transactions with or perform services
for us in the ordinary course of business.
If so indicated in the applicable prospectus supplement, we will
authorize underwriters or other persons acting as our agents to
solicit offers by certain institutions to purchase securities
from us pursuant to delayed delivery contracts providing for
payment and delivery on the date stated in the prospectus
supplement. Each contract will be for an amount not less than,
and the aggregate amount of securities sold pursuant to such
contracts shall not be less nor more than, the respective
amounts stated in the prospectus supplement. Institutions with
whom the contracts, when authorized, may be made include
commercial and savings banks, insurance companies, pension
funds, investment companies, educational and charitable
institutions and other institutions, but shall in all cases be
subject to our approval. Delayed delivery contracts will not be
subject to any conditions except that:
|
|
|
|
|
the purchase by an institution of the securities covered under
that contract shall not at the time of delivery be prohibited
under the laws of the jurisdiction to which that institution is
subject; and
|
|
|
|
if the securities are also being sold to underwriters acting as
principals for their own account, the underwriters shall have
purchased such securities not sold for delayed delivery. The
underwriters and other persons acting as our agents will not
have any responsibility in respect of the validity or
performance of delayed delivery contracts.
|
8
Certain agents, underwriters and dealers, and their associates
and affiliates may be customers of, have borrowing relationships
with, engage in other transactions with,
and/or
perform services, including investment banking services, for us
or one or more of our respective affiliates in the ordinary
course of business.
In order to facilitate the offering of the securities, any
underwriters may engage in transactions that stabilize, maintain
or otherwise affect the price of the securities or any other
securities the prices of which may be used to determine payments
on such securities. Specifically, any underwriters may overallot
in connection with the offering, creating a short position for
their own accounts. In addition, to cover overallotments or to
stabilize the price of the securities or of any such other
securities, the underwriters may bid for, and purchase, the
securities or any such other securities in the open market.
Finally, in any offering of the 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
repurchases previously distributed securities in transactions to
cover syndicate short positions, in stabilization transactions
or otherwise. Any of these activities may stabilize or maintain
the market price of the securities above independent market
levels. Any such underwriters are not required to engage in
these activities and may end any of these activities at any time.
Under
Rule 15c6-1
of the Exchange Act, trades in the secondary market generally
are required to settle in three business days, unless the
parties to any such trade expressly agree otherwise. The
applicable prospectus supplement may provide that the original
issue date for your securities may be more than three scheduled
business days after the trade date for your securities.
Accordingly, in such a case, if you wish to trade securities on
any date prior to the third business day before the original
issue date for your securities, you will be required, by virtue
of the fact that your securities initially are expected to
settle in more than three scheduled business days after the
trade date for your securities, to make alternative settlement
arrangements to prevent a failed settlement.
The securities may be new issues of securities and may have no
established trading market. The securities may or may not be
listed on a national securities exchange. We can make no
assurance as to the liquidity of or the existence of trading
markets for any of the securities.
LEGAL
MATTERS
Unless the applicable prospectus supplement indicates otherwise,
the validity of the issuance of the securities in respect of
which this prospectus is being delivered will be passed upon by
Wilmer Cutler Pickering Hale and Dorr LLP.
