                Forward-Looking Information May Prove Inaccurate

         This prospectus contains or incorporates by reference "forward-looking
statements" as that term is used in federal securities laws about our financial
condition, results of operations and business. These statements include, among
others:

     o   statements concerning the benefits that we expect will result from our
         business activities and certain transactions we have completed, such as
         increased revenues, decreased expenses and avoided expenses and
         expenditures; and


     o   statements of our expectations, beliefs, future plans and strategies,
         anticipated developments and other matters that are not historical
         facts.


          These statements may be made expressly in this prospectus, or may be
incorporated by reference to other documents filed with the Securities and
Exchange Commission (the "SEC"). You can identify many of these statements by
looking for words such as "believes," "expects," "anticipates," "estimates," or
similar expressions used in this prospectus or incorporated by reference in this
prospectus.

         These forward-looking statements are subject to numerous assumptions,
risks and uncertainties that may cause our actual results to be materially
different from any future results expressed or implied by us in those
statements, including the risks and uncertainties of a research-based
pharmaceutical and health care company detailed in the documents filed with the
SEC and incorporated by reference in this prospectus.

         Because the statements are subject to risks and uncertainties, actual
results may differ materially from those expressed or implied by the
forward-looking statements. We caution you not to place undue reliance on the
statements, which speak only as of the date of this prospectus or, in the case
of documents incorporated by reference, the date of the applicable document.

         The cautionary statements contained or referred to in this section
should be considered in connection with any subsequent written or oral
forward-looking statements that we or persons acting on our behalf may issue. We
do not undertake any obligation to review or confirm analysts' expectations or
estimates or to release publicly any revisions to any forward-looking statements
to reflect events or circumstances after the date of this prospectus or to
reflect the occurrence of unanticipated events.

                         Description of Debt Securities

         We have summarized below material provisions of the debt securities
that we will offer and sell pursuant to this prospectus and material provisions
of the indenture. However, you should understand that this is only a summary. We
have not described all of the provisions of the indenture. We have filed the
indenture with the SEC, and we suggest that you read the indenture. We are
incorporating by reference the provisions of the indenture referred to by
section numbers and summarized below. The following summary is qualified in its
entirety by those provisions of the indenture. For purposes of this section, the
term "Company" refers only to Wyeth and not to any of its subsidiaries.

General

         The debt securities will be issued under an indenture dated as of April
10, 1992, as amended on October 13, 1992 between the Company and JPMorgan Chase
Bank as trustee.

         Numerical references in parentheses below are to sections in the
indenture. Wherever particular sections or defined terms of the indenture are
referred to, such sections or defined terms are incorporated herein by reference
as part of the statement made, and the statement is qualified in its entirety by
such reference.

         We will describe the particular terms and conditions of any series of
debt securities offered in the applicable prospectus supplement. The prospectus
supplement, which we will file with the SEC, may or may not modify the general
terms found in this prospectus. For a complete description of any series of debt
securities, you should read both this prospectus and the prospectus supplement
relating to that series of debt securities.

         As a holder of debt securities issued under the indenture, you will be
one of our unsecured creditors and will have a right to payment equal to that of
our other unsecured creditors. As of the date of this prospectus, the principal
amount of debt securities outstanding under the indenture is $6.1 billion. The
indenture does not limit the amount of debt securities that may be issued under
it and provides that debt securities may be issued under it from time to time in
one or more series.

         With respect to each particular series of debt securities that we offer
by this prospectus, the prospectus supplement will describe the following terms
of each series of debt securities:

     o    the title of the series;


     o    the maximum aggregate  principal amount, if any,  established for debt
          securities of the series;

          debt securities of the series shall bear interest may be determined;


     o    the date or dates from which interest, if any, shall accrue;


     o    the dates on which  any  accrued  interest  shall be  payable  and the
          record dates for the interest payment dates;


     o    the percentage of the principal amount at which the debt securities of
          the series will be issued,  and if less than face amount,  the portion
          of the  principal  amount that will be payable  upon  acceleration  of
          those debt

          currency;


     o    any index,  formula or other method that we must use to determine  the
          amount of any  payment of  principal,  any  premium or interest on the
          debt securities of the series;


     o    if the debt  securities  of the  series are  subordinated  in right of
          payment   to  other   securities,   the   terms  and   conditions   of
          subordination;


     o    whether,  and under what  conditions,  we will be  required to pay any
          additional amounts;


     o    whether  the  debt   securities  of  the  series  will  be  issued  in
          certificated or book-entry form;


     o    any  addition to, or change in, the events of default with respect to,
          or covenants relating to, the debt securities in the series;


     o    whether  the  debt  securities  of  the  series  will  be  subject  to
          defeasance as provided in the indenture; and


     o    any  other  specific  terms  and  conditions  of the  series  of  debt
          securities.


         If we sell any series of debt securities that we may pay in, or that
are denominated in, one or more foreign currencies, currency units or composite
currencies, we will disclose any material applicable restrictions, elections,
tax consequences, specific terms and other information with respect to that
series of debt securities and the relevant currencies, currency units or
composite currencies in the prospectus supplement relating to the offer of that
series.

         We may also offer and sell a series of the debt securities as original
issue discount securities, bearing no interest or interest at a rate that at the
time of issuance is below market rates, or at a substantial discount below their

                                       7


stated principal amount. We will describe the income tax consequences and other
special considerations applicable to any original issue discount securities of
that kind described in the prospectus supplement relating to that series.

 Restrictive Covenants

         Limitation on Liens. The indenture provides with respect to each series
of debt securities that, unless the terms of such series of debt securities
provide otherwise, the Company will not create or assume, or permit any
Restricted Subsidiary (as defined below) to create or assume, any mortgage,
pledge, security interest or lien ("Mortgage") of or upon any Principal Property
(as defined below) or shares of capital stock or indebtedness of any Restricted
Subsidiary, unless the debt securities of such series are secured by such a
Mortgage equally and ratably with all other indebtedness thereby secured. Such
covenant does not apply to:

     (a)  Mortgages on any Principal  Property,  shares of stock or indebtedness
          of any  corporation  existing at the time such  corporation  becomes a
          Restricted Subsidiary;

     (b)  Mortgages on any Principal Property acquired,  constructed or improved
          by the  Company  or any  Restricted  Subsidiary  after the date of the
          indenture  which are  created or assumed  contemporaneously  with such
          acquisition,  construction or improvement or within 120 days after the
          latest of the acquisition,  completion of construction  (including any
          improvement on any existing  property) or  commencement  of commercial
          operation of such property;

     (c)  Mortgages on any Principal Property or shares of stock or indebtedness
          acquired  from a  corporation  merged  with or into the  Company  or a
          Restricted Subsidiary;

     (d)  Mortgages  on any  Principal  Property  to  secure  indebtedness  of a
          Restricted Subsidiary to the Company or another Restricted Subsidiary;

     (e)  Mortgages on any  Principal  Property in favor of the United States of
          America or any State thereof or The Commonwealth of Puerto Rico or any
          political subdivisions thereof to secure progress or other payments or
          to secure indebtedness  incurred for the purpose of financing the cost
          of  acquiring,  constructing  or  improving  such  Principal  Property
          (including  Mortgages  incurred in connection with pollution  control,
          industrial   revenue,   Title  XI  maritime   financings   or  similar
          financings);

     (f)  Mortgages existing on the date of the indenture; and

     (g)  any  extension,  renewal or  replacement  (or  successive  extensions,
          renewals  or  replacements),  in  whole or in  part,  of any  Mortgage
          referred to in the foregoing clauses (a) to (f),  inclusive.  (Section
          3.6)

         Notwithstanding the foregoing, the Company and its Restricted
Subsidiaries may, without securing the debt securities of any series, create or
assume Mortgages (which would otherwise be subject to the foregoing
restrictions) securing indebtedness in an aggregate amount which, together with
all other Exempted Debt (as defined) of the Company and its Restricted
Subsidiaries, does not at the time exceed 10% of the Company's consolidated net
tangible assets (defined in the indenture as total assets less current
liabilities and intangible assets). (Section 3.6)

         Sale and Lease-Back Transactions. The indenture provides with respect
to each series of debt securities that, unless the terms of such series of debt
securities provide otherwise, Sale and Lease-Back Transactions (as defined) by
the Company or any Restricted Subsidiary of any Principal Property are
prohibited except in the event that (a) the Company or such Restricted
Subsidiary would be entitled to incur indebtedness secured by a Mortgage on the
Principal Property to be leased equal in amount to the Attributable Debt (as
defined) with respect to such Sale and Lease-Back Transaction without equally or
ratably securing the debt securities of such series; or (b) the Company applies
an amount equal to the fair value of the property sold to the purchase of
Principal Property or to the retirement of Long-Term Indebtedness (as defined)
of the Company within 120 days of the effective date of any such Sale and
Lease-Back Transaction. In lieu of applying such amount to such retirement the
Company may

                                       8

deliver debt securities to the trustee for cancellation, such debt
securities to be credited at the cost thereof to the Company. (Section 3.7)

         Notwithstanding the foregoing, the Company or any Restricted Subsidiary
may enter into any Sale and Lease-Back Transaction (which would otherwise be
subject to the foregoing restrictions) as long as the Attributable Debt
resulting from such Sale and Lease-Back Transaction, together with all other
Exempted Debt (as defined) of the Company and its Restricted Subsidiaries, does
not at the time exceed 10% of the Company's consolidated net tangible assets.
(Section 3.7)

         The term "Principal Property" means the Company's principal office
building and each manufacturing plant or research facility located within the
territorial limits of the States of the United States of America or The
Commonwealth of Puerto Rico (but not within any other territorial possession) of
the Company or a Subsidiary except such as the Board of Directors by resolution
reasonably determines (taking into account, among other things, the importance
of such property to the business, financial condition and earnings of the
Company and its consolidated Subsidiaries taken as a whole) not to be a
Principal Property. (Section 1.01)

         The term "Subsidiary" means any corporation the outstanding securities
of which having ordinary voting power to elect a majority of the board of
directors of such corporation are at the time owned or controlled by the Company
or by one or more Subsidiaries or by the Company and one or more Subsidiaries,
other than a Subsidiary which is engaged primarily in financing receivables,
making loans, extending credit, providing financing from foreign sources or
other activities of a character conducted by a finance company. The term
"Restricted Subsidiary" means any Subsidiary which owns a Principal Property.
(Section 1.01)

         Consolidation, Merger and Sale of Assets. The Company may not
consolidate with, merge into, or sell or convey its property and assets
substantially as an entirety to another entity unless the successor entity
assumes all the obligations of the Company under the indenture and the debt
securities and after giving effect thereto, no default or Event of Default shall
have occurred and be continuing and such successor entity shall be incorporated
under the laws of the United States or any State. Thereafter, except in the case
of a conveyance by way of lease, all such obligations of the Company shall
terminate. (Section 9.1) The indenture further provides with respect to each
series of debt securities that, unless the terms of such series of debt
securities provide otherwise, the Company will not, and will not permit any
Restricted Subsidiary to, merge or consolidate with another corporation, or sell
all or substantially all of its assets to another corporation for a
consideration other than the fair value thereof in cash, if such other
corporation has outstanding obligations secured by a mortgage which, after such
transaction, would extend to any Principal Property owned by the Company or such
Restricted Subsidiary prior to such transaction, unless the Company or such
Restricted Subsidiary shall have effectively provided that the debt securities
of such series will be secured by a mortgage which, upon completion of the
aforesaid transaction, will rank prior to such mortgage of such other
corporation on any Principal Property. (Section 3.6)

         The provisions of the indenture do not afford holders of the debt
securities protection in the event of a highly leveraged or other transaction
involving the Company that may adversely affect holders of the debt securities.

Events of Default

         An Event of Default with respect to debt securities of any series is
defined under the indenture as being:

     (a)  default in payment of any  principal  of the debt  securities  of such
          series,  either at maturity,  upon any  redemption,  by declaration or
          otherwise;

     (b)  default for 30 days in payment of any interest on any debt  securities
          of such series;

     (c)  default  for  90  days  after  written  notice  in the  observance  or
          performance of any other covenant or agreement in the debt  securities
          of such series or the indenture;

     (d)  certain events of bankruptcy, insolvency or reorganization; or

                                       9


     (e)  any other Event of Default provided for in the debt securities of such
          series or in the supplemental indenture creating such debt securities.
          (Section 5.1)

         The indenture provides that (i) if an Event of Default described in the
foregoing clauses (a), (b), (c) or (e) (if the Event of Default under clause (c)
or (e) is with respect to less than all series of debt securities then
outstanding) shall have occurred and be continuing, either the trustee or the
holders of not less than 25% in principal amount of the debt securities of all
affected series (treated as one class) then outstanding may then declare the
principal of all debt securities of all such affected series and interest
accrued thereon to be due and payable immediately; and (ii) if an Event of
Default described in the foregoing clauses (d), (c) or (e) (if the Event of
Default under clause (c) or (e) is with respect to all series of debt securities
then outstanding) shall have occurred and be continuing, either the trustee or
the holders of not less than 25% in principal amount of all debt securities then
outstanding (treated as one class) may declare the principal of all debt
securities and interest accrued thereon to be due and payable immediately, but
upon certain conditions such declarations may be annulled and past defaults may
be waived (except a continuing default in payment of principal of or interest on
such debt securities) by the holders of a majority in principal amount of the
debt securities of all such affected series then outstanding. (Section 5.1)

         Subject to certain limitations, the holders of a majority in principal
amount of the outstanding debt securities (treated as one class) may 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. (Section
5.9)

         The indenture provides that no holder of debt securities may institute
any action under the indenture (except actions for payment of overdue principal
or interest) unless such holder previously shall have given to the trustee
written notice of default and continuance thereof and unless the holders of not
less than 25% in principal amount of the debt securities of each affected series
(treated as one class) then outstanding shall have requested the trustee to
institute such action and shall have offered the trustee reasonable indemnity,
the trustee shall not have instituted such action within 60 days of such request
and the trustee shall not have received direction inconsistent with such written
request by the holders of a majority in principal amount of the debt securities
of each affected series (treated as one class). (Section 5.6)

         The indenture contains a covenant that the Company will file annually
with the trustee a certificate of no default or a certificate specifying any
default that exists. (Section 3.5)

Defeasance

         The indenture provides that, with respect to each series of debt
securities, unless the terms of such series of debt securities provide
otherwise, the Company shall be discharged from its obligations under the debt
securities of such series if the Company irrevocably deposits with the trustee
in trust (i) cash, or (ii) in the case of any series of debt securities the
payments on which may only be made in Dollars (as defined), U.S. Government
Obligations (as defined), maturing as to principal and interest at such times
and in such amounts as will insure the availability of cash or (iii) any
combination thereof, sufficient, in the opinion of a nationally recognized firm
of independent public accountants to pay when due the principal and interest on
all debt securities of such series and any mandatory sinking fund payments
provided that certain other conditions are met. These conditions include the
delivery to the trustee of an opinion of counsel to the effect that the Holders
of the debt securities will not recognize income, gain or loss for federal
income tax purposes as a result of such deposit, defeasance and discharge and
will be subject to federal income tax on the same amount and in the same manner
and at the same times as would have been the case if such deposit, defeasance
and discharge had not occurred. Upon such discharge, the provisions of the
indenture with respect to the debt securities of such series shall no longer be
in effect except for certain rights, including registration of transfer and
exchange of debt securities of such series and substitution of mutilated,
defaced, destroyed, lost or stolen debt securities. (Section 10.1)

         The Company will be released from its obligations with respect to the
covenants relating to the limitation on liens and sale and lease-back
transactions and the restriction on consolidations, mergers and sale of assets
with respect to the debt securities on and after the date the conditions set
forth below are satisfied ("covenant defeasance"). Covenant defeasance means
that, with respect to the outstanding debt securities of any series, the Company
may omit to comply with and will have no liability in respect of any term,
condition or limitation with respect to such provisions of the indenture and
such omission to comply shall not constitute an Event of Default, but

                                       10


the other terms of the indenture and such debt securities shall be unaffected
thereby. The following are the conditions to covenant defeasance: (a) the
Company has irrevocably deposited or caused to be deposited with the trustee in
trust (i) cash, or (ii) in the case of any series of debt securities the
payments on which may only be made in Dollars, U.S. Government Obligations
maturing as to principal and interest at such times and in such amounts as will
insure the availability of cash or (iii) a combination thereof, sufficient, in
the opinion of a nationally recognized firm of independent public accountants to
pay when due (A) the principal and interest on all debt securities of such
series and (B) any mandatory sinking fund payments; (b) no Event or Default or
event which with notice or lapse of time or both would become an Event of
Default with respect to the debt securities shall have occurred and be
continuing on the date of such deposit; and (c) certain other customary
conditions. (Section 10.1)

Modification of the Indenture

         The indenture provides that the Company and the trustee may enter into
supplemental indentures without the consent of the holders of debt securities
to:

     (a)  secure any debt securities;

     (b)  evidence the assumption by a successor  corporation of the obligations
          of the Company;

     (c)  add covenants for the protection of the holders of debt securities;

     (d)  cure any ambiguity or correct any inconsistency in the indenture;

     (e)  establish the forms or terms of debt securities of any series; and

     (f)  evidence  the  acceptance  of  appointment  by  a  successor  trustee.
          (Section 8.1)

         The indenture also contains provisions permitting the Company and the
trustee, with the consent of the holders of not less than a majority in
principal amount of debt securities of each series then outstanding and
affected, to add any provisions to, or change in any manner or eliminate any of
the provisions of, the indenture or modify in any manner the rights of the
holders of the debt securities of each series so affected; provided that the
Company and the trustee may not, without the consent of the holder of each
outstanding debt security affected thereby,

     (a)  extend the final  maturity of the  principal  of any debt  security or
          reduce the principal  amount  thereof or reduce the rate or extend the
          time of payment of  interest  thereon or reduce any amount  payable on
          the  redemption  thereof or change the currency in which the principal
          thereof  (including any amount in respect of original issue  discount)
          or  interest  thereon is payable or reduce the amount of any  original
          issue  discount  security  payable  upon  acceleration  or provable in
          bankruptcy  or alter certain  provisions of the indenture  relating to
          debt securities not denominated in U.S. dollars or impair the right to
          institute suit for the enforcement of any payment on any debt security
          when due;

     (b)  reduce the aforesaid percentage in principal amount of debt securities
          of any series, the consent of the holders of which is required for any
          such modification; or

     (c)  modify  any  of  the  foregoing  provisions  except  to  increase  the
          aforesaid  percentage  or to  provide  that  other  provisions  of the
          indenture  may not be amended  or waived  without  the  consent of the
          holder of each outstanding debt security  affected  thereby.  (Section
          8.2)

The Trustee

         The trustee, JPMorgan Chase Bank, is the administrative agent and a
lending bank under our credit facilities. In addition, one or more affiliates of
the trustee have performed and may continue to perform various commercial
banking, investment banking and financial advisory services for us.

                           Tax Consequences To Holders

         The prospectus supplement will contain a summary of the material U.S.
federal income tax consequences, if any, to persons investing in the debt
securities offered by that prospectus supplement. In addition, if the tax laws
of foreign countries are material to a particular series of debt securities, a
prospectus supplement may describe the principal income tax consequences of
acquiring, owning and disposing of such series of debt securities. The summary
of tax consequences contained in the prospectus supplement will be presented for
informational purposes only, however, and will not be intended as legal or tax
advice to prospective purchasers. You should consult your own tax advisor prior
to any acquisition of debt securities.

                              Plan of Distribution

General

         The debt securities may be sold:

          o    to or through  underwriting  syndicates  represented  by managing
               underwriters;


          o    through one or more underwriters  without a syndicate for them to
               offer and sell to the public;


          o    through dealers or agents; or


          o    to investors directly in negotiated sales or in competitively bid
               transactions.


         The prospectus supplement for each series of securities we sell will
describe that offering, including:

          o    the name or names of any underwriters;


          o    the purchase price and the proceeds to us from that sale;


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


          o    any  initial   public   offering   price  and  any  discounts  or
               concessions allowed or reallowed or paid to dealers; and


          o    any securities exchanges on which the securities may be listed.


Underwriters

         If underwriters are used in the sale, we will execute an underwriting
agreement with those underwriters relating to the securities that we will offer.
Unless otherwise set forth in the prospectus supplement, the obligations of the
underwriters to purchase these securities will be subject to conditions. The
underwriters will be obligated to purchase all of these securities if any are
purchased.

         The securities subject to the underwriting agreement will be acquired
by the underwriters for their own account and may be resold by them from time to
time in one or more transactions, including negotiated transactions, at a fixed
public offering price or at varying prices determined at the time of sale.
Underwriters may be deemed to have received compensation from us in the form of
underwriting discounts or commissions and may also receive commissions from the
purchasers of these securities for whom they may act as agent. Underwriters may
sell these securities to or through dealers. These dealers may receive
compensation in the form of discounts, concessions or commissions from the
underwriters and/or commissions from the purchasers for whom they may act as
agent. Any initial public offering price and any discounts or concessions
allowed or reallowed or paid to dealers may be changed from time to time.

         We also may sell the securities in connection with a remarketing upon
their purchase, in connection with a redemption or repayment, by a remarketing
firm acting as principal for its own account or as our agent. Remarketing firms
may be deemed to be underwriters in connection with the securities that they
remarket.

         We may authorize underwriters to solicit offers by institutions to
purchase the securities subject to the underwriting agreement from us, at the
public offering price stated in the prospectus supplement under delayed delivery
contracts providing for payment and delivery on a specified date in the future.
If we sell securities under these delayed delivery contracts, the prospectus
supplement will state that as well as the conditions to which these delayed
delivery contracts will be subject and the commissions payable for that
solicitation.

                                       13


Agents

         We may also sell any of the securities through agents designated by us
from time to time. We will name any agent involved in the offer or sale of these
securities and will list commissions payable by us to these agents in the
prospectus supplement. These agents will be acting on a best efforts basis to
solicit purchases for the period of its appointment, unless we state otherwise
in the prospectus supplement.

Direct Sales

         We may sell any of the securities directly to purchasers. In this case,
we will not engage underwriters or agents in the offer and sale of these
securities.

Indemnification

         We may indemnify underwriters, dealers or agents who participate in the
distribution of securities against certain liabilities, including liabilities
under the Securities Act of 1933 and agree to contribute to payments which these
underwriters, dealers or agents may be required to make.

No Assurance of Liquidity

         The securities offered hereby may be a new issue of securities with no
established trading market. Any underwriters that purchase securities from us
may make a market in these securities. The underwriters will not be obligated,
however, to make a market and may discontinue market-making at any time without
notice to holders of the securities. We cannot assure you that there will be
liquidity in the trading market for any securities of any series.


                                  Legal Matters

         The validity of the debt securities offered by this prospectus and any
prospectus supplement will be passed upon for us by Simpson Thacher & Bartlett

Item 15.   Indemnification of Directors and Officers

         Article Nine of the Company's Restated Certificate of Incorporation
provides for the elimination of personal monetary liabilities of directors of
the Company for breaches of certain of their fiduciary duties to the full extent
permitted by Section 102(b)(7) of the General Corporation Law of Delaware (the
"GCL"). Section 102(b)(7) of the GCL enables a corporation in its certificate of
incorporation to eliminate or limit the personal liability of members of its
board of directors to the corporation or its shareholders for monetary damages
for violations of a director's fiduciary duty as a director. Such a provision
has no effect on the availability of equitable remedies, such as an injunction
or rescission, for breach of fiduciary duty. In addition, no such provision may
eliminate or limit the liability of a director for breaching his or her duty of
loyalty, failing to act in good faith, engaging in intentional misconduct or
knowingly violating the law, paying an unlawful dividend or approving an illegal
stock repurchase, or obtaining an improper personal benefit.

         Section 145 of the GCL provides that a corporation may indemnify
directors and officers as well as other employees and individuals against
expenses (including attorneys' fees), judgments, fines and amounts paid in
settlement in connection with specified actions, suits or proceedings, whether
civil, criminal, administrative or investigative (other than an action by or in
the right of the corporation--a "derivative action"), if they acted in good
faith and in a manner they reasonably believed to be in or not opposed to the
best interests of the corporation and, with respect to any criminal action or
proceedings, had no reasonable cause to believe their conduct was unlawful. A
similar standard is applicable in the case of derivative actions, except that
indemnification only extends to expenses (including attorneys' fees) actually
and reasonably incurred in connection with the defense or settlement of such
action, and the statute requires court approval before there can be any
indemnification where the person seeking indemnification has been found liable
to the corporation. The statute provides that it is not exclusive of other
indemnification that may be granted by a corporation's by-laws, disinterested
director vote, stockholder vote, agreement or otherwise.

         The Company's By-laws provide that the Company is authorized to provide
indemnification and to advance expenses to its directors, officers and employees
in respect of claims, actions, suits or proceedings based upon, arising from,
relating to or by reason of the fact that any such director or officer serves in
such capacity with the Company or at the request of the Company in any capacity
with any other corporation or entity of which the Company is or was a
stockholder, creditor or otherwise interested.


                                      II-1


         The Company maintains directors' and officers' liability insurance
which insures against liabilities that directors or officers of the Company may
incur in such capacities.

         The form of Underwriting Agreement filed as Exhibit 1.1 provides for
the indemnification of the Company, its controlling persons, its directors and
officers by any agents, dealers or underwriters who execute those agreements
against certain liabilities which might arise from information furnished to the
Company by such indemnifying party.

Item 16.   Exhibits

Number    Description

12.2 Computation  of  Ratio  of  Earnings  to  Fixed  Charges  (incorporated  by
     reference to Exhibit 12 to the  Registrant's  Quarterly Report on Form 10-Q
     for the quarter ended September 30, 2003, filed on November 12, 2003).

written consent of Arthur Andersen LLP, the Company's former independent public
accountants, to the incorporation by reference into this registration statement
of its report covering the Company's financial statements for the year ended
December 31, 2000. The Company has dispensed with the requirement to file the
written consent of Arthur Andersen LLP in reliance on Rule 437a promulgated
under the Securities Act of 1933, as amended. Since the Company has not been
able to obtain the written consent of Arthur Andersen LLP, investors will not be
able to recover against Arthur Andersen LLP under Section 11 of the Securities
Act for any untrue statements of a material fact contained in the financial
statements for the year ended December 31, 2000 audited by Arthur Andersen LLP
incorporated by reference herein or any omissions to state a material fact
required to be stated therein.

Item 17.   Undertakings

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;

                                      II-2


               (ii) to reflect  in the  prospectus  any facts or events  arising
                    after the effective date of the  registration  statement (or
                    the most recent  post-effective  amendment  thereof)  which,
                    individually  or in the  aggregate,  represent a fundamental
                    change  in the  information  set  forth in the  registration
                    statement; and

               (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 (1)(i) and (1)(ii) above 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 SEC by the registrant pursuant to section 13
         or section 15(d) of the Exchange Act that are incorporated by reference
         in the registration statement;

         (2) that, for the purpose of determining any liability under the
         Securities Act, 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; and

         (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.

The undersigned registrant hereby further undertakes that for purposes of
determining any liability under the Securities Act:

         (1) each filing of the registrant's annual report pursuant to section
         13(a) or section 15(d) of the Exchange Act (and, where applicable, each
         filing of any employee benefit plan's annual report pursuant to section
         15(d) of the Exchange Act) 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;

         (2) the information omitted from the form of prospectus filed as part
         of this registration statement in reliance upon Rule 430A and contained
         in a form of prospectus filed by the registrant pursuant to Rule
         424(B)(1) or (4) or 497(h) under the Securities Act shall be deemed to
         be part of this registration statement as of the time it was declared
         effective; and

         (3) each post-effective amendment that contains a form of prospectus
         shall be deemed to be a new registration statement relating to the
         securities offered therein, and the offering of such securities at that
         time shall be deemed to be the initial bona fide offering thereof.

Insofar as indemnification for liabilities arising under the Securities Act may
be permitted to directors, officers and controlling persons of the registrant
pursuant to the foregoing provisions, or otherwise, except pursuant to the
insurance policies referred to in Item 15, the registrant has been advised that
in the opinion of the Securities and Exchange Commission, such indemnification
is against public policy as expressed in the Securities Act and is, therefore,
unenforceable. In the event that a claim for indemnification against such
liabilities (other than the payment by such registrant of expenses incurred or
paid by a director, officer or controlling person of such registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.


                                      II-3
