      Certain  statements  in  this  Registration  Statement  or  the  documents
incorporated   by   reference   in  this   Registration   Statement   constitute
"forward-looking  statements"  within  the  meaning  of the  Private  Securities
Litigation Reform Act of 1995. These  forward-looking  statements  involve known
and unknown  risks,  uncertainties  and other factors which may cause the actual
results,  performance  or  achievements  of  Iconix  Brand  Group,  Inc.  to  be
materially  different  from any  future  results,  performance  or  achievements
expressed or implied by such forward-looking  statements.  Such factors include,
among  others,  those set forth  under the  caption  "Risk  Factors."  The words
"believe," "expect,"  "anticipate," "intend," and "plan" and similar expressions

                                   The Company

      Iconix is in the business of licensing the CANDIE'S(R),  BONGO(R), BADGLEY
MISCHKA(R), JOE BOXER(R) and RAMPAGE(R) trademarks on a variety of young women's
footwear,  apparel and fashion  products.  Through its wholly owned  subsidiary,
Bright Star  Footwear,  LLC, the Company also  arranges for the  manufacture  of
footwear  products  for mass  market  and  discount  retailers  and  receives  a
commission on the sales of these products.

      Iconix was  incorporated  under the laws of the State of Delaware in 1978.
Its principal  executive offices are located at 215 West 40th Street,  New York,
New York 10018, and its telephone number is (212) 730-0300.

      Unless the context  requires  otherwise,  reference in this  prospectus to
"we", "us" ,"our", "Iconix", or "Company" refers to Iconix Brand Group, Inc. and
its subsidiaries.

                                  Risk Factors

      We operate in a changing  environment  that  involves  numerous  known and
unknown  risks and  uncertainties  that could  materially  adversely  affect our
operations. The following highlights some of the factors that have affected, and
in the future could affect, our operations.

We have  incurred  losses  during  recent  fiscal years and future  losses could
negatively affect our cash flows and business operations.

      Although we recorded  net income of $3.3  million for the six months ended
June 30, 2005 (including a non-cash tax benefit of $1.8 million) and $241,000 in
the 11-month  period ended  December 31, 2004,  in the fiscal year ended January
31,  2004 we  sustained  net  losses of $11.3  million,  and net  losses of $3.9
million, $2.3 million and $8.2 million during our fiscal years ended January 31,
2003, 2002 and 2001,  respectively.  We cannot  guarantee that we will not incur
losses in the future.


                                       3


We are no longer directly  engaged in the design,  manufacture,  distribution or
sale of branded apparel,  footwear or other fashion products and,  consequently,
our revenues are dependent on the success of certain licensees of those rights.

      Although  the  licensing  agreements  for our brands  usually  require the
advance payment to us of certain fees and provide for certain guaranteed minimum
royalty  payments  to  us,  the  failure  by  the  licensees  to  satisfy  their
obligations  under the agreements could result in the termination of the license
agreements.  Moreover,  during  the  terms  of  the  license  agreements  we are
substantially  dependent  upon the  abilities  of the  licensees to maintain the
quality, marketability and consumer recognition of the licensed products bearing
our brands.  In addition,  failure by the  licensees  to meet their  production,
manufacturing or distribution  requirements  could negatively impact their sales
and resulting royalty payments to us which, in turn, would materially  adversely
affect our revenues and business operations.  Moreover, the failure by licensees
to meet their financial  obligations to us could  jeopardize our ability to meet
the debt service coverage ratio in connection with the asset-backed notes issued
by one of our  subsidiaries  which  would  give the note  holders  the  right to
foreclose on our  trademarks  and other related  intellectual  property  assets,
which are the security for the debt.

Our business is dependent on continued market  acceptance of the products of our
licensees that bear our trademarks and of the CANDIE'S,  BONGO, BADGLEY MISCHKA,
JOE BOXER and RAMPAGE trademarks.

      Our ability to achieve continued market  acceptance of products  utilizing
our trademarks as well as market  acceptance of any future  products that may be
offered by us or by our licensees that bear our trademarks, is subject to a high
degree of  uncertainty.  Our ability or the ability for our licensees to achieve
market acceptance by new customers or continued market acceptance by existing or
past  customers may require  substantial  additional  marketing  efforts and the
expenditure of  significant  funds by us to maintain a demand for such products.
Additional marketing efforts and expenditures may not result in increased market
acceptance of products of our licensees or increased sales of such products.  We
are  materially  dependent on the sale of products  bearing our trademarks for a
significant  portion of our revenues.  Although our licensees  guarantee minimum
net sales and minimum guaranteed royalties to us, a failure of our trademarks or
products to achieve or maintain  market  acceptance  could reduce our  licensing
revenues, thereby negatively impacting cash flows.



                                       4


We had a working  capital  deficit at June 30, 2005, have incurred a substantial
amount of  indebtedness  and to the  extent  that cash flow from our  continuing
operations is insufficient to meet our debt  obligations,  we may be required to
seek  additional  financing  to  satisfy  our  obligations  or lose title to our
trademarks.

As of the date of this prospectus there is approximately  $103 million principal
outstanding on seven-year asset backed notes issued by one of our  subsidiaries,
IP  Holdings,  LLC,  referred to as IP Holdings or IPH. The notes were issued in
four transactions,  $ 20 million in August 2002, $2.6 million in March 2004, $45
million in July 2005 in connection  with our  acquisition of the JOE BOXER brand
from Joe Boxer,  LLC and $40 million in September  2005. Of the additional  debt
incurred  in  September  2005,  $28  million  was  used in  connection  with our
acquisition  of the RAMPAGE  brand on September  16, 2005 and the  remaining $12
million  is  available  to us for  potential  future  acquisitions.  We  will be
required  to repay the $12  million on  November  15,  2005 if we do not use the
funds in  connection  with an  acquisition  The payment of the  principal of and
interest on the notes will be made from  amounts  received by IP Holdings  under
license  agreements  with  various  licensees  of  the  assets  acquired  and IP
Holdings'  other  intellectual  property  assets.  In the event  that there is a
default in the payment on the notes,  the note holders have a security  interest
in our  trademarks  and have the  right to  foreclose  on those  trademarks.  In
addition,   in  connection  with  our  acquisition  in  April  2002  from  Sweet
Sportswear,  Inc.,  referred to as Sweet, of the remaining  equity  interests in
Unzipped Apparel,  LLC,  referred to as Unzipped,  the joint venture formed with
Sweet, we issued to Sweet $11.0 million principal amount of senior  subordinated
notes the amount of which have been  reduced to  approximately  $2.8  million at
June 30,  2005 as a result of certain  shortfalls  in the net income of Unzipped
that Sweet  guaranteed  under the terms of an  agreement  under which it managed
Unzipped until August 2004. As of the date of this prospectus we are involved in
litigation  with Sweet and  certain of its  affiliates  with  respect to certain
matters  pertaining to Unzipped.  Moreover,  we had a working capital deficit of
approximately  $3.3 million at June 30, 2005.  We believe that we will  generate
sufficient revenues from our licensing operations to satisfy our obligations for
the foreseeable future. However, in the event that projected cash flow proves to
be insufficient to satisfy our cash requirements including our debt obligations,
we may be required to seek additional funds through,  among other means,  public
or  private  equity or debt  financing,  which may  result  in  dilution  to our
stockholders,  or if we were to default on our obligations to the holders of the
asset backed notes they could foreclose on our trademarks.

A  substantial  portion  of  our  licensing  revenues  are  concentrated  in two
retailers.

Two of our largest  licenses are each  concentrated  at a single  retailer.  The
CANDIE'S brand is concentrated at Kohl's Department  Stores,  Inc., which by the
end of 2006 will be the exclusive licensee for all product  categories,  and the
JOE BOXER brand,  which has an exclusive license with Kmart for all core product
categories.  Because we are  dependent on these two  licensees for a substantial
portion  of our  licensing  revenue,  if  Kohl's  or  Kmart  (which  came out of
bankruptcy  in May 2003 and is  currently  owned by  Sears  Holding  Corp.)  had
financial  difficulties  or ceased to operate,  it would  negatively  impact our
revenue and cash flows.

A recession in the fashion  industry or rapidly  changing  fashion  trends could
harm our operating results.

      The fashion  industry is cyclical,  with  purchases of apparel and related
goods tending to decline during  recessionary  periods when disposable income is
low. A poor general economic climate could have a negative impact on our and our
licensees'  ability to compete for limited  consumer  resources.  Moreover,  our
future success depends in substantial part on our and our licensees'  ability to
anticipate  and respond to  changing  consumer  demands and fashion  trends in a
timely manner. The footwear and wearing apparel industries are generally subject
to constantly  changing  fashion  trends.  If we or our  licensees  misjudge the
market for a particular  product or product  line, it may result in an increased
inventory  of unsold and  outdated  finished  goods,  which could  increase  the
affected  licensee's  operating  costs  without  a  corresponding   increase  in
revenues.


                                       5


Our licensees are subject to risks and  uncertainties  of foreign  manufacturing
that could  interrupt  operations or increase  operating cost thereby  impacting
their ability to deliver goods to the market.

      Substantially  all of the products sold by our licensees are  manufactured
overseas.  We and our licensees are subject to various risks inherent in foreign
manufacturing,  including  fluctuations  in  foreign  currency  exchange  rates;
shipping  delays;  and  international   political,   regulatory,   and  economic
developments,  all of which  can have a  significant  impact  on the  licensee's
operating costs and consequently, our earnings.

      Our licensees also import certain finished products and assume all risk of
loss and  damage  once their  suppliers  ship these  goods.  If these  goods are
destroyed or damaged during shipment it could impact our revenues as a result of
its licensees' delay in delivering finished products to customers.

Because of the  intense  competition  in our  markets  and the  strength  of our
competitors,  we and  our  licensees  may not be able  to  continue  to  compete
successfully.

      The apparel,  footwear and fashion industries are extremely competitive in
the United States and our licensees face intense and substantial competition for
our product lines.  In general,  competitive  factors  include  quality,  price,
style,  name  recognition  and  service.  In  addition,   the  presence  in  the
marketplace  of various  fads and the  limited  availability  of shelf space can
affect  competition.  Many competitors of our licensees have greater  financial,
distribution,  marketing  and other  resources  than they have and have achieved
significant  name  recognition  for  their  brand  names.  We may not be able to
continue to compete  successfully  in the market with  respect to the  licensing
arrangements. Our licensees may be unable to successfully compete in the markets
for such products.

We may not be able to protect  our  proprietary  rights or avoid  claims that we
infringe on the proprietary rights of others.

      We own trademark  registrations for CANDIE'S,  BONGO, BADGLEY MISCHKA, JOE
BOXER  and  RAMPAGE,   among  others,  and  believe  that  our  trademarks  have
significant  value and are important to the  marketing of our  products.  To the
extent  that  the  trademarks  owned or used by us are  deemed  to  violate  the
proprietary rights of others, or in the event that these trademarks would not be
upheld if challenged,  we would,  in either such event,  be prevented from using
the  trademarks,  which could have an adverse effect on us. In addition,  we may
not have the financial resources necessary to enforce or defend trademarks owned
or used by us.

We are dependent upon our key executives and other  personnel,  whose loss would
adversely impact our business.

      Our  success  is largely  dependent  upon the  efforts  of Neil Cole,  our
President,   Chief  Executive  Officer  and  Chairman,  and  certain  other  key
executives.  Although we have entered into an employment agreement with Mr. Cole
that  expires in December  2007,  the loss of his and/or  other key  executive's
services would have a material adverse effect on our business and prospects. Our
success  is also  dependent  upon  our  ability  to hire and  retain  additional
qualified sales and marketing personnel in connection with the design, marketing
and  distribution  of our  products  as well as our  ability  to hire and retain
administrative  personnel.  We may not be able to hire or retain such  necessary
personnel.


                                       6


Provisions  in our  charter  and  share  purchase  rights  plan may  prevent  an
acquisition of Iconix.

      Certain  provisions  of our  Certificate  of  Incorporation  and our Share
Purchase Rights Plan could have the effect,  either alone or in combination with
each other,  of making more  difficult,  or  discouraging  an acquisition of our
company  deemed  undesirable  by our  Board of  Directors.  Our  Certificate  of
Incorporation  provides  for the issuance of up to  75,000,000  shares of common
stock and 5,000,000 shares of preferred stock. As of the date of this prospectus
there were approximately  33,150,000 shares of our common stock and no shares of
preferred stock outstanding. Additional shares of our common stock and preferred
stock are therefore available for future issuance without stockholder  approval.
The Share Purchase Rights Plan,  commonly known as a "poison pill," states that,
in the event than an individual or entity acquires 15% of the outstanding shares
of our stockholders  other than the acquirer may purchase  additional  shares of
our common stock for a fixed price.  The existence of  authorized  but un-issued
capital stock,  together with the existence of the Share  Purchase  Rights Plan,
could have the effect of discouraging an acquisition of us.

We are subject to certain litigation that could harm us.

      We are currently a plaintiff and  cross-defendant  in a litigation pending
in California  state court involving  Unzipped,  and a defendant in a litigation
pending in federal district court in New York involving a former  supplier.  Our
financial  condition  could be adversely  impacted if we are required to pay the
monetary damages sought by the  cross-complainants  in the California action and
the  plaintiff  in  the  New  York  action,  or if it is  adjudicated  that  the
contractual rights concerning Unzipped are invalid.

The market price of our common stock may be volatile.

      The market price of our common stock may be highly  volatile.  Among other
things, disclosures of our operating results, announcements of various events by
us or our  competitors  and the  development  and  marketing of new products may
cause the market  price of our common stock to change  significantly  over short
periods of time.  Sales of shares  under this  prospectus  may have a depressive
effect on the market price of our common stock.

Future  sales of shares of our common stock could affect the market price of our
common stock and our ability to raise additional capital.

      We have previously issued a substantial  number of shares of common stock,
which are eligible for resale under Rule 144 of the  Securities  Act of 1933, as
amended,  referred to as the Securities Act, and may become freely tradable.  We
have also  registered  a  substantial  number of shares of common stock that are
issuable  upon  the  exercise  of  options  and  warrants  and  have  previously
registered  for  resale and have  agreed to  register  for resale a  substantial
number  of   restricted   shares  of  common  stock  held  by  certain   selling
stockholders,  which are in  addition  to the shares of our common  stock  being
offered by the selling stockholders  pursuant to this Prospectus.  If holders of
options or warrants  choose to exercise their purchase rights and sell shares of
common stock in the public market, or if holders of currently  restricted shares
choose to sell such shares in the public market under Rule 144 or otherwise, the
prevailing market price for our common stock may decline. Future public sales of
shares of common stock may adversely affect the market price of our common stock
or our future ability to raise capital by offering equity securities.

                                 Use of Proceeds

      We will not  receive  any  proceeds  from the sale of common  stock by the
selling stockholders named in this prospectus.

      We have agreed to pay certain expenses in connection with the registration
of the shares being offered by the selling stockholders.

                              Selling Stockholders

      Based on information provided by the selling  stockholders,  the following
table sets forth certain information regarding the selling stockholders:

      The  table  below  assumes  for  calculating  each  selling  stockholder's
beneficial  and  percentage  ownership  that  options,  warrants or  convertible
securities that are held by such  stockholder (but not held by any other person)
and are  exercisable  within  60 days from the date  this  prospectus  have been
exercised  or  converted.  The table also  assumes the sale of all of the shares
being offered by the selling stockholders pursuant to this prospectus.

                              Plan of Distribution

      We have been  advised  that the  selling  stockholders,  which may include
pledgees, donees, transferees or other  successors-in-interest who have received
shares from the selling stockholders after the date of this prospectus, may from
time to time,  sell all or a  portion  of the  shares  in  privately  negotiated
transactions or otherwise, at fixed prices that may be changed, at market prices
prevailing at the time of sale,  at prices  related to these market prices or at
negotiated prices.

      All costs,  expenses and fees in connection  with the  registration of the
shares  offered  by this  prospectus  other  than any  counsel  for the  selling
stockholders, shall be borne by us. Brokerage costs, if any, attributable to the
sale of shares will be borne by the selling stockholders.

      The shares may be sold by the selling  stockholders  by one or more of the
following methods:

      o     block  trades in which the broker or dealer so engaged  will attempt
            to sell the shares as agent but may position and resell a portion of
            the shares as principal to facilitate the transaction;


                                       9



      o     purchases  by a broker  or dealer as  principal  and  resale by such
            broker dealer for its account;

      o     an  exchange  distribution  in  accordance  with  the  rules  of the
            applicable exchange;

      o     over-the  counter  distribution  in accordance with the rules of the
            Nasdaq National Market;

      o     ordinary brokerage transactions and transactions in which the broker
            solicits purchasers;

      o     through  the  writing of put or call  options on the shares or other
            hedging   transactions   (including   the  issuance  of   derivative
            securities),  whether the options or other derivative securities are
            listed on an option or other exchange or otherwise;

      o     privately negotiated transactions;

      o     a combination of any such methods of sale; and

      o     any other method permitted pursuant to applicable law.


      The  transactions  described  above  may or may  not  involve  brokers  or
dealers.

      The selling  stockholders will not be restricted as to the price or prices
at which the selling  stockholder  may sell its  shares.  Sales of shares by the
selling  stockholders may depress the market price of our common stock since the
number of shares which may be sold by the selling  stockholder may be relatively
large  compared to the  historical  average  weekly trading of our common stock.
Accordingly,  if the selling  stockholders were to sell, or attempt to sell, all
of such  shares  at once or  during  a short  time  period,  we  believe  such a
transaction could adversely affect the market price of our common stock.

      From time to time the  selling  stockholders  may pledge its shares  under
margin  provisions  of  customer  agreements  with its brokers or under loans or
other   arrangements  with  third  parties.   Upon  a  default  by  the  selling
stockholders,  the  broker or such  third  party may offer and sell any  pledged
shares from time to time.

      In  effecting   sales,   brokers  and  dealers   engaged  by  the  selling
stockholders  may arrange  for other  brokers or dealers to  participate  in the
sales as agents or  principals.  Brokers or dealers may receive  commissions  or
discounts from the selling  stockholders or, if the broker-dealer  acts as agent
for  the  purchaser  of  such  shares,  from  the  purchaser  in  amounts  to be
negotiated,  which  compensation  as to a particular  broker  dealer might be in
excess of customary commissions which are not expected to exceed those customary
in the types of transactions involved. Broker-dealers may agree with the selling
stockholders to sell a specified number of such shares at a stipulated price per
share,  and to the extent the  broker-dealer  is unable to do so acting as agent
for a selling  stockholder,  to purchase as principal  any unsold  shares at the
price  required  to  fulfill  the  broker-dealer   commitment  to  such  selling
stockholder.  Broker-dealers  who acquire  shares as  principal  may then resell
those shares from time to time in transactions


                                       10


      o     in the over-the counter market or otherwise;

      o     at prices and on terms prevailing at the time of sale;

      o     at prices related to the then-current market price; or

      o     in negotiated transactions.

      These resales may involve block transactions or sales to and through other
broker-dealers, including any of the transactions described above. In connection
with these sales, these broker-dealers may pay to or receive from the purchasers
of those shares  commissions as described  above.  The selling  stockholders may
also  sell the  shares  in open  market  transactions  under  Rule 144 under the
Securities Act, rather than under this prospectus.

      The selling stockholders and any broker-dealers or agents that participate
with the  selling  stockholders  in  sales of the  shares  may be  deemed  to be
"underwriters" within the meaning of the Securities Act in connection with these
sales. In this event, any commissions received by these broker-dealers or agents
and any profit on the resale of the shares purchased by them may be deemed to be
underwriting commissions or discounts under the Securities Act.

      We have agreed to indemnify  certain of the selling  stockholders  against
certain liabilities under the Securities Act. The selling stockholders may agree
to  indemnify  any  agent,   dealer  or  broker-dealer   that   participates  in
transactions   involving  sales  of  the  shares  against  certain  liabilities,
including liabilities arising under the Securities Act.

      The selling  stockholders  are  subject to  applicable  provisions  of the
Securities  Exchange Act of 1934 and the SEC's rules and regulations,  including
Regulation  M, which  provisions  may limit the timing of purchases and sales of
the shares by the selling stockholders.

      In order to comply with certain  states'  securities  laws, if applicable,
the  shares  may be sold in  those  jurisdictions  only  through  registered  or
licensed brokers or dealers. In certain states the shares may not be sold unless
the shares have been  registered or qualified for sale in such state,  or unless
an exemption from registration or qualification is available and is obtained.

                                  Legal Matters

      Blank Rome LLP of New York,  New York will pass upon the  validity  of the
shares of common stock being offered by this prospectus.

Item 14. Other Expenses of Issuance and Distribution.

      The expenses payable by the Registrant in connection with the issuance and
distribution of the securities  being registered  (estimated  except for the SEC
Registration fee)are as follows:

Item 15. Indemnification of Directors and Officers.

      Section  145 of the  General  Corporation  Law of the  State  of  Delaware
("GCL") provides for the indemnification of officers and directors under certain
circumstances  against  expenses  incurred in successfully  defending  against a
claim and  authorizes  Delaware  corporations  to indemnify  their  officers and
directors under certain  circumstances against expenses and liabilities incurred
in legal  proceedings  involving  such persons  because of their being or having
been an officer or director.

      Section  102(b) of the GCL permits a  corporation,  by so providing in its
certificate of incorporation,  to eliminate or limit director's liability to the
corporation  and its  shareholders  for monetary  damages arising out of certain
alleged breaches of their fiduciary duty.  Section 102(b)(7) of the GCL provides
that no such  limitation  of liability  may affect a director's  liability  with
respect to any of the following:  (i) breaches of the director's duty of loyalty
to the corporation or its shareholders;  (ii) acts or omissions not made in good
faith or which  involve  intentional  misconduct  of knowing  violations of law;
(iii) liability for dividends paid or stock repurchased or redeemed in violation
of the GCL; or (iv) any transaction  from which the director derived an improper
personal  benefit.  Section  102(b)(7)  does not authorize any limitation on the
ability of the  corporation or its  shareholders  to obtain  injunctive  relief,
specific performance or other equitable relief against directors.

      Article Ninth of the  registrant's  Certificate of  Incorporation  and the
registrant's By-laws provide that all persons who the registrant is empowered to
indemnify  pursuant to the  provisions of Section 145 of the GCL (or any similar
provision  or  provisions  of  applicable  law at the time in effect),  shall be
indemnified  by the  registrant  to  the  full  extent  permitted  thereby.  The
foregoing  right of  indemnification  shall not be deemed to be exclusive of any
other rights to which those seeking  indemnification  may be entitled  under any
by-law,   agreement,   vote  of  shareholders  or  disinterested  directors,  or
otherwise.


                                      II-1


      Article Tenth of the registrant's  Certificate of  Incorporation  provides
that no director of the registrant shall be personally  liable to the registrant
or its stockholders for any monetary damages for breaches of fiduciary duty as a
director,  except for  liability  (i) for any breach of the  director's  duty of
loyalty to the registrant or its stockholders; (ii) for acts or omissions not in
good faith or which involve  intentional  misconduct  or a knowing  violation of
law; (iii) under Section 174 of the GCL; or (iv) for any transaction  from which
the director derived an improper personal benefit.

      The   registrant's   employment   agreements   with  Mr.  Neil  Cole,  the
registrant's  Chief Executive Officer,  Mr. William Sweedler,  an Executive Vice
President of the  registrant  and Ms.  Deborah  Sorell Stehr,  the  registrant's
Senior Vice President and General Counsel  generally provide that the registrant
shall indemnify each of them for the consequences of all acts and decisions made
by such person while  performing  services for the registrant.  These agreements
also require the  registrant  to use its best efforts to obtain  directors'  and
officers' liability insurance for such persons.

      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
and is, therefore, unenforceable.

Item 17. Undertakings

Undertaking Required by Regulation S-K, Item 512(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, as amended (the "Securities Act");

            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;


                                      II-2


            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 clauses (i) and (ii) do not apply if the  Registration
Statement is on Form S-3, Form S-8 or Form F-3, and the information  required to
be  included in a  post-effective  amendment  by such  clauses is  contained  in
periodic  reports filed with or furnished to the  Commission  by the  Registrant
pursuant to Section 13 or 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, each such  post-effective  amendment shall be deemed to be a new
registration  statement  relating to the  securities  offered  therein,  and the
offering  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.

Undertaking Required by Regulation S-K, Item 512(b).

      The  undersigned  registrant  hereby  undertakes  that,  for  purposes  of
determining  any  liability  under  the  Securities  Act,  each  filing  of  the
registrant's  annual report pursuant to Section 13(a) or 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 initial bona fide offering thereof.

Undertaking required by Regulation S-K, Item 512(h).

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