                                   THE COMPANY

         Magellan Petroleum Corporation (the "Company" or "MPC") is engaged in
the sale of oil and gas and the exploration for and development of oil and gas
reserves. As of the date of this prospectus, MPC's principal asset was a 55%
equity interest in its subsidiary, Magellan Petroleum Australia Limited
("MPAL"), which has one class of stock that is publicly held and traded in
Australia.

         MPAL's major assets are two petroleum production leases covering the
Mereenie oil and gas field (35% working interest) and one petroleum production
lease covering the Palm Valley gas field (52% working interest). Both fields are
located in the Amadeus Basin in the Northern Territory of Australia. Santos
Ltd., a publicly owned Australian company, owns a 48% interest in the Palm
Valley field, a 65% interest in the Mereenie field and 10.1% of MPAL's
outstanding stock. On February 10, 2004, Santos Ltd sold 3.8 million shares of
MPAL's stock and reduced its interest from 18.3% to 10.1%. Origin Energy
Limited, a publicly owned Australian company, owned 17.1% of MPAL's outstanding
stock at June 30, 2003. On July 10, 2003, a subsidiary of Origin Energy, Sagasco
Amadeus Pty. Limited, agreed to exchange 1.2 million shares of MPAL for 1.3
million shares of the Company's common stock. After the exchange was completed
on September 2, 2003, the Company's interest in MPAL increased to 55% and Origin
Energy's interest decreased to 14.5%.

         MPC has a direct 2.67% carried interest in the Kotaneelee gas field
located in the southeast Yukon Territory of Canada. Devon Canada Corporation is
the operator of this partially developed field which is connected to a major
pipeline system. During the month of December 31, 2003, average production from
the field was approximately 22.3 million cubic feet per day. During September
2003, the litigants in the Kotaneelee litigation entered into a settlement
agreement. During October 2003, the Company received approximately $851,000,
after Canadian withholding taxes and reimbursement of certain legal costs. The
plaintiffs have terminated all litigation against the defendants related to the
field, including the claim that the defendants failed to fully develop the
field. Since each party has agreed to bear its own legal costs, there were no
taxable costs assessed against any of the parties. See Item 3 - Legal
Proceedings of the Company's amended Form 10-K/A for the fiscal year ended June
30, 2003, for a discussion of litigation relating to the Kotaneelee field.

Mereenie Field

         MPAL (35%) and Santos (65%), the operator, (together known as the
Mereenie Producers) own the Mereenie field which is located in the Amadeus Basin
of the Northern Territory. MPAL's share of the Mereenie field proved developed
oil reserves was approximately 380,000 barrels and 12.1 billion cubic feet (bcf)
of gas at June 30, 2003. The Mereenie Producers have agreed to install
additional compression equipment in the field at a cost of $13.1 million (MPAL
share $6.4 million) that will increase field deliverability and partially meet
certain gas contract requirements. In addition, two gas wells will be drilled to
meet the gas contractual requirements until June 2007.

         During fiscal 2003, MPAL's share of oil sales was 145,000 barrels and
3.8 bcf of gas sold which is subject to net overriding royalties aggregating
4.0625% and the statutory government royalty of 10%. During fiscal 2003, the oil
was transported by means of a 167-mile eight-inch oil pipeline from the field to
an industrial park near Alice Springs. Most of the oil was then shipped south
approximately 950 miles by rail and road to a refinery in the Adelaide area of
South Australia. Effective July 1, 2003, the oil is being trucked to the Port
Bonython Export Terminal, Whyalla, South Australia for sale at approximately the
same cost as the previous method. The cost of transporting the oil to the
terminal is being borne by the Mereenie Producers. The Mereenie Producers are
providing Mereenie gas in the Northern Territory to the Power and Water
Authority (PAWA) and Gasgo Pty. Ltd., a company PAWA wholly owns, for use in
Darwin and other Northern Territory centers. See "Gas Supply Contracts" below.

         The leases covering the Mereenie field were renewed in November 2002
for an additional term of 21 years.

Palm Valley Field

         MPAL has a 52% interest in, and is the operator, of the Palm Valley gas
field which is also located in the Amadeus Basin of the Northern Territory.
Santos, the operator of the Mereenie field, owns the remaining 48% interest in
Palm Valley which provides gas to meet the Alice Springs and Darwin supply
contracts with PAWA. See "Gas Supply Contracts" below. MPAL's share of the Palm
Valley proved developed reserves was16.8 bcf at June 30, 2003. During fiscal
2003, MPAL's share of gas sales was 3.1 bcf which is subject to a 10% statutory
government royalty and net overriding royalties aggregating 5%. MPAL plans to
drill an additional development well, Palm Valley-11, later in 2003 to increase
gas deliverability. PAWA will pay for the cost of the well under the gas supply
agreement.

         The lease covering the Palm Valley field, which was due to expire in
November 2003, was renewed for an additional 21 years during November 2003.
Negotiations are still ongoing with the Aboriginal landowners.

Gas Supply Contracts

         In 1983, the Palm Valley Producers (MPAL and Santos) commenced the sale
of gas to Alice Springs under a 1981 agreement. In 1985, the Palm Valley
Producers and Mereenie Producers signed agreements for the sale of gas to PAWA
for use in PAWA's Darwin generating station and at a number of other generating
stations in the Northern Territory. The gas is being delivered via the 922-mile
Amadeus Basin to Darwin gas pipeline which was built by an Australian
consortium. Since 1985, there have been several additional contracts for the
sale of Mereenie gas. Both the Palm Valley and Mereenie contracts expire in the
year 2009. Under the 1985 contracts, there is a difference in price between Palm
Valley gas and most of the Mereenie gas for the first 20 years of the 25 year
contracts which takes into account the additional cost to the pipeline
consortium to build a spur line to the Mereenie field and increase the size of
the pipeline from Palm Valley to Mataranka. The price of gas under the Palm
Valley and Mereenie gas contracts is adjusted quarterly to reflect changes in
the Australian Consumer Price Index.






         At June 30, 2003, MPAL's commitment to supply gas under the above
         agreements was as follows:
                                    Period                        Bcf

The following chart illustrates the various relationships between MPC and the
various companies discussed above.

                                  RISK FACTORS

         You should carefully consider the risks described below before buying
the shares of common stock offered hereby. The risks and uncertainties described
below are not the only ones we face. Additional risks and uncertainties not
presently known to us or that we currently deem immaterial may also
significantly impair our business, financial condition and results of
operations.

         If any of the following risks actually occur, our business, financial
condition and results of operations could be materially harmed, the trading
price of our common stock could decline and you may lose all or part of your
investment.

Fluctuations  In Our  Operating  Results And Other Factors May Depress Our Stock
Price.

         During the past few years, the equity trading markets in the United
States have experienced declines in the value of securities generally and also
extreme price volatility that has often been unrelated to the operating
performance of particular companies. These broad market declines and
fluctuations may adversely affect the trading price of our common stock. From
time to time, there may be significant volatility in the market price of our
common stock. If we are unable to operate the Company at a profit, investors
could sell shares of our common stock at or after the time that it becomes
apparent that the expectations of the market may not be realized, resulting in a
decrease in the market price of our common stock.

The Company's Principal Oil & Gas Property and the Properties Owned by Our
Principal Subsidiary Could Stop Producing Oil And Gas.

         MPAL's Palm Valley and Mereenie fields could stop producing oil and gas
or there could be a material decrease in productions levels at the fields. Since
these are the two principal revenue producing properties of MPAL, any decline in
production levels at these properties could cause MPAL's revenues to decline,
thus reducing the amount of dividends paid by MPAL to the Company. Any such
adverse impact on the revenues being received by the Company from MPAL could
restrict our ability to explore and develop oil and gas properties in the
future.

         In addition, the Kotaneelee gas field, which is now the Company's main
source of revenue, could stop producing natural gas, produce gas in decreased
amounts, or be shut-in completely (so that production would cease). In this
event, the Company would experience a decline in revenues and would be forced to
rely completely on our receipt of dividends from MPAL.

We Only Have One Full Time Employee, And Our Operations Could Be Disrupted If He
Was Unable Or Unwilling To Perform His Duties.

         We only have one full time employee, James R. Joyce, our President and
  Chief Financial Officer. Mr. Joyce has an employment agreement with us that
  expires on June 30, 2004. Mr. Joyce notified the Company in December 2003 that
  he will retire as of June 30, 2004, at the end of the term of his employment
  agreement and resign as an officer of the Company as of that date. If we are
  unable to find a replacement in a timely manner for Mr. Joyce, our operations
  could face significant delay and disruption until a suitable replacement is
  found to succeed Mr. Joyce. Any such delay or disruption could also prevent
  the achievement of our business objectives. We our working on a succession
  plan, but we do not have one in place at this time.

There Are Risks Inherent In The Operation Of Oil And Gas Ventures.

         An investment in the Company involves the inherent risks of companies
that operate oil and gas exploration and production ventures. Despite favorable
seismic and geological surveys and discoveries at particular properties, only
subsequent drilling operations, undertaken at substantial costs to the Company,
MPAL or third parties, can determine whether commercial development of oil and
gas reserves is economically feasible. If the Company and MPAL are not able to
successfully develop their properties into marketable oil and gas reserves, the
Company's revenues may decline and our stock price could be adversely impacted.

         The odds against discovery of commercially exploitable hydrocarbon
reserves are always substantial. Even if a discovery is made, the Company's
ability to exploit the discovered hydrocarbons will depend upon a number of
additional factors, including, but not limited to, its ability to finance
development costs, the availability of markets and equipment and the resolution
of technical and engineering problems associated with the discovery, extraction
and transportation of hydrocarbon reserves.

There Are Risks  Inherent  In  Foreign  Operations  Such As  Adverse  Changes In
Currency  Values And  Foreign  Regulations  Relating To MPAL's  Exploration  And
Development Operations And To MPAL's Payment Of Dividends To The Company.

         The properties in which the Company has interests are located outside
the United States and are subject to certain risks related to the indirect
ownership and development of foreign properties, including government
expropriation, adverse changes in currency values and foreign exchange controls,
foreign taxes, nationalization and other laws and regulations, any of which may
adversely affect the Company's properties. In addition, MPAL's principal present
customer for gas in Australia is the Northern Territory Government, which also
has substantial regulatory authority over MPAL's oil and gas operations.
Although there are currently no exchange controls on the payment of dividends to
the Company by MPAL, such payments could be restricted by Australian foreign
exchange controls, if implemented.

Three Common Directors of MPC and MPAL May Have Potential Conflicts Of Interest.

         The Company and MPAL have three common directors who serve on the
boards of each entity and owe separate fiduciary duties to each entity and its
stockholders. Under certain circumstances, these individuals could have
potential conflicts of interest by reason of the separate fiduciary duties they
owe to each entity.

Our Restated  Certificate of Incorporation  Includes Provisions That Could Delay
Or Prevent A Change In Control Of Our  Company  That Our  Shareholders  Consider
Favorable.

         Article Twelfth of our Restated Certificate of Incorporation of the
Company, as amended, provides that any matter to be voted upon at any meeting of
stockholders must be approved not only by a simple majority of the shares voted
at such meeting, but also by a majority of the shareholders present in person or
by proxy and entitled to vote at the meeting. This provision may have the effect
of making it more difficult to take corporate action than customary "one share
one vote" provisions, because it may not be possible to obtain the necessary
majority of both votes.

         As a consequence, Article Twelfth may make it more difficult that a
takeover of the Company will be consummated, which could prevent the Company's
shareholders from receiving a premium for their shares. In addition, an owner of
a substantial number of shares of our common stock may be unable to influence
our policies and operations through the shareholder voting process (e.g., to
elect directors).

         In addition, Article Thirteenth of our Restated Certificate of
Incorporation requires the approval of 66 2/3rds % of the voting shareholders
and of the voting shares for the consummation of any business combination (such
as a merger, consolidation, other acquisition proposal or sale, transfer or
other disposition of $5 million or more of the Company's assets) involving our
company and certain related persons (generally, any 10% or greater stockholders
and their affiliates and associates). This higher vote requirement may deter
business combination proposals which shareholders may consider favorable.

Our Dividend Policy Could Depress Our Stock Price and Harm Our Stockholders.

         We have never declared or paid dividends on our common stock and do not
anticipate declaring or paying any dividends in the foreseeable future. We plan
to retain any future earnings to reduce our accumulated deficit and finance
growth. As a result, our dividend policy could depress the market price for our
common stock and cause investors to lose some or all of their investment.

We May Issue A Substantial  Number Of Shares Of Our Common Stock Under Our Stock
Option Plans And Shareholders May Be Adversely Affected By The Issuance Of Those
Shares.

         As of February 2004, there were 770,000 stock options outstanding, all
of which are fully vested and exercisable. There were also 230,000 options
available for future grants under the Company's Stock Option Plan. If all of
these options, which total 1,000,000, were awarded and exercised these shares
would represent approximately 3.7% of our outstanding common stock and would
dilute the interests of our existing shareholders and could adversely affect the
market price of our common stock.

If The Company's Shares Are Delisted From Trading On The Nasdaq SmallCap Market,
Their Liquidity And Value Could Be Reduced.

         In order for the Company to maintain the listing of its shares of
common stock on the Nasdaq SmallCap Market, the Company's shares must maintain a
minimum bid price of $1.00 as set forth in Marketplace Rule 4310(c)(4). If the
bid price of the Company's shares trade below $1.00 for 30 consecutive trading
days, then the bid price of the Company shares must trade at $1.00 or more for
10 consecutive trading days during a 180 day grace period to regain compliance
with the rule. At present, the Company meets the requirement for two 180 day
grace periods to regain compliance. If the Company shares were to be delisted
from trading on the Nasdaq SmallCap market, then most likely the shares would be
traded on the Electronic Bulletin Board. The delisting of the Company's shares
could adversely impact the liquidity and value of the Company's shares of common
stock.

(1)      Sagasco Amadeus Pty. Limited is a direct wholly owned subsidiary of
         Sagasco NT Pty. Ltd., which is in turn a direct wholly owned subsidiary
         of Origin Energy Resources Ltd. ("Resources"), which is in turn a
         direct wholly owed subsidiary of Origin Energy Limited, a diversified
         energy company based in Sydney, Australia.

         The shares being offered by Sagasco were acquired on September 2, 2003
pursuant to a Share Sale Agreement entered into between the Company and Sagasco
on July 10, 2003. Under this Agreement, the Company agreed to issue 1,300,000
shares of our common stock as payment for, and in consideration of, the
Company's acquisition from Sagasco of 1,200,000 shares of MPAL, the Company's
52.44% owned subsidiary. The Company's acquisition of the 1,200,000 shares of
MPAL common stock increased the Company's holdings in MPAL from 52.44% to 55%.

         Following the closing of the Share Sale Agreement, Sagasco exercised
its right to request that we register the shares offered hereby pursuant to a
Registration Rights Agreement, dated September 2, 2003, that we entered into in
connection with the Company's acquisition of the 1,200,000 shares of MPAL from
Sagasco.





                                 USE OF PROCEEDS

         The selling shareholder is offering all of the shares covered by this
prospectus. We will not receive any of the proceeds from the sale of the shares.

                              PLAN OF DISTRIBUTION

         The shares may be sold from time to time by Sagasco, as set forth in
the Registration Rights Agreement. Sagasco will act independently of us in
making decisions with respect to the timing, manner and size of each sale.
Sagasco may make these sales on the Nasdaq SmallCap Market or otherwise, at
prices and terms that are then-prevailing or at prices related to the
then-current market price, at fixed prices or in privately negotiated
transactions. Sagasco may use one or more of the following methods to sell the
shares of common stock:

o        a block trade in which Sagasco's broker or dealer will attempt to sell
         the shares as agent, but may position and resell all or a portion of
         the block as a principal to facilitate the transaction;

o        a broker or dealer may purchase the common stock as a principal and
         then resell the common stock for its own account pursuant to this
         prospectus;

o        an over-the-counter distribution in accordance with the rules of the
         applicable automated interdealer quotation system;

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

o        sales through underwriters or dealers who may receive compensation in
         the form of underwriting discounts, concessions or commissions from the
         selling shareholder or such successors in interest and/or from the
         purchasers of shares for whom they act as agents; and

o        the pledge of the shares as security for any loan or obligation,
         including pledges to brokers or dealers who may, from time to time,
         themselves effect distribution of the shares or interests therein.

         Sagasco may enter into hedging transactions with broker-dealers in
connection with sales of the shares or otherwise. In these transactions,
broker-dealers may engage in short sales of the shares in the course of hedging
the positions they assume with Sagasco. Sagasco may enter into option or other
transactions with broker-dealers that require the delivery to the broker-dealer
of the shares. The broker-dealer may then resell or otherwise transfer the
shares under this prospectus. Sagasco also may loan or pledge the shares to a
broker-dealer. The broker-dealer may sell the loaned shares, or upon a default
the broker-dealer may sell the pledged shares under this prospectus.



         The aggregate proceeds to Sagasco from the sale of the shares will be
the purchase price of the common stock sold less the aggregate selling
commissions, if any, and other expenses of issuance and distribution not borne
by us. Broker-dealers or agents may receive compensation in the form of
commissions, discounts or concessions from Sagasco. Broker-dealers or agents may
also receive compensation from the purchasers of the shares for whom they act as
agents or to whom they sell as principal, or both. Compensation as to a
particular broker-dealer might be in excess of customary commissions and will be
in amounts to be negotiated in connection with the sale. Broker-dealers or
agents and any other participating broker-dealers or Sagasco may be deemed to be
"underwriters" within the meaning of Section 2(a)(11) of the Securities Act in
connection with sales of the shares. Accordingly, any such commission, discount
or concession received by them and any profit on the resale of the shares
purchased by them may be deemed to be underwriting discounts or concessions
under the Securities Act. Because Sagasco may be deemed to be an "underwriter"
within the meaning of Section 2(a)(11) of the Securities Act, it may be subject
to the prospectus delivery requirements of the Securities Act.

         To the extent required, the specific shares of common stock to be sold,
the purchase price, public offering price, the names of any such agent, dealer
or underwriter, and any applicable commission or discount with respect to a
particular offering will be described in a supplement to this prospectus.

         Pursuant to the Registration Rights Agreement, we have agreed to bear
certain expenses of registration of the shares under the federal and state
securities laws and of any offering and sale hereunder, but not including
certain expenses such as (1) underwriting discounts, selling commissions and
stock transfer taxes attributable to the sale of the shares and (2) fees and
expenses of Sagasco's counsel.

         The Registration Rights Agreement provides that we will indemnify
Sagasco against certain liabilities, including liabilities under the Securities
Act. Sagasco has agreed to indemnify us and against certain liabilities,
including liabilities under the Securities Act.

         There can be no assurance that Sagasco will sell any or all of the
shares of our common stock offered by them hereunder.

                                  LEGAL MATTERS

         Murtha Cullina LLP, Hartford, Connecticut, will pass upon certain legal
matters with respect to the shares of common stock registered hereunder.

Item 15.  Indemnification of Directors and Officers.

         The Restated Certificate of Incorporation of the Company, as amended,
contains the following provisions respecting indemnification.

         FIFTEENTH: A director of this Corporation shall not be personally
         liable to the Corporation or any of its stockholders for monetary
         damages for breach of fiduciary duty as a director, except for
         liability (i) for any breach of the director's duty of loyalty to the
         Corporation 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 Delaware General Corporation Law,
         or (iv) for any transaction from which the director derived an improper
         personal benefit. If the Delaware General Corporation Law hereafter is
         amended, changed or modified in any way to further eliminate or limit
         the liability of directors to the Corporation or its stockholders or
         third parties, then directors of the Corporation, in addition to the
         circumstances in which directors are not personally liable as set forth
         in the preceding sentence, shall also not be personally liable to the
         Corporation or its stockholders or third parties for monetary damages
         to such further extent permitted by such amendment, change or
         modification.

         Any repeal or modification of the foregoing paragraph shall not
         adversely affect the rights of any director of the Corporation relating
         to claims arising in connection with events which took place prior to
         the date of such repeal or modification.

         SIXTEENTH: The Corporation shall enter into appropriate agreements with
         its directors and officers (and with such other employees and agents as
         the Board of Directors deems appropriate in its sole and exclusive
         discretion) to both indemnify them and advance to them the funds for
         litigation expenses to the fullest extent permitted by the laws of the
         State of Delaware, as the same presently exist or may hereafter be
         amended, changed or modified.

         Any repeal or modification of the foregoing paragraph shall not
         adversely affect the rights of any director or officer (or any such
         employees or agents) of the Corporation relating to claims arising in
         connection with events which took place prior to the date of such
         repeal or modification.

         Article III, Section 9 of the Company's By-Laws which provides for
indemnification agreements with its directors and officers is substantially
identical to Article SIXTEENTH of the Certificate of Incorporation and provides
as follows:

         SECTION 9. The Corporation shall enter into appropriate agreements with
         its directors and officers (and with such other employees and agents as
         the Board of Directors deems appropriate in its sole and exclusive
         discretion) both to indemnify such directors and officers (and such
         other employees and agents, if any) and to advance to such directors
         and officers (and such other employees and agents, if any) the funds
         for litigation expenses to the fullest extent permitted by the laws of
         the State of Delaware, as the same presently exist or may hereafter be
         amended, changed or modified.

         Any repeal or modification of the foregoing paragraph shall not
         adversely affect the rights of any director or officer (or any such
         employee or agent) of the corporation relating to claims arising in
         connection with events which took place prior to the date of such
         repeal or modification.

         Section 145 of the Delaware General Corporation Law provides for the
indemnification of directors and officers. Generally Section 145 provides for
indemnification to cover the claims and lawsuits of two general categories. The
first category, third-party claims, includes lawsuits brought against the
Company and its directors or officers by third parties who claim to have been
injured by some unlawful action. Section 145 provides that a director or officer
subject to this class of claim is entitled to indemnification for any amount
paid for the judgment or settlement and any expenses incurred in a reasonable
defense thereof, provided that the director or officer (i) acted in good faith
and in a manner which he reasonably believed to be in or not opposed to the best
interests of the Company, and (ii) with respect to any criminal action or
proceeding, had no reasonable cause to believe that his conduct was unlawful.

         The second category of claims for which a director or officer could
seek indemnification are claims by or in the right of the Company, whether such
claims are made by the Company directly or by a stockholder in a derivative
action. Examples in this category include breach by a director of his duty of
loyalty to the Company. As to this category of claims and lawsuits, Section 145
provides specifically that the director or officer may obtain indemnification of
expenses actually and reasonably incurred by him in connection with the defense
or settlement of such action or suit if he acted in good faith and in a manner
he reasonably believed to be in or not opposed to the best interests of the
Company and if a court of appropriate jurisdiction approves such
indemnification. However, directors and officers are not entitled to be
indemnified under the statute to recover amounts paid in damages or settlement
of such suits.

         Section 145, by its terms, is not exclusive. Section 145(f) provides in
pertinent part: "The indemnification and advancement of expenses provided by, or
granted pursuant to, the other subsections of this section shall not be deemed
exclusive of any other rights to which those seeking indemnification or
advancement of expenses may be entitled under any by-law, agreement, vote of
stockholders or disinterested directors or otherwise."

         In accordance with Article SIXTEENTH of its Certificate of
Incorporation, the Company has entered into indemnification agreements with each
of its directors and officers.

         In 1985, the Company purchased $100,000 of directors and officer's
liability insurance coverage from an unaffiliated Bermuda company at a cost of
$100,000 plus an annual $7,500 service fee during the period of the policy. The
policy amount was increased to $200,000 in 1998. The Company is credited with
investment income from the policy premium during the term of the policy and all
or a portion of such premium will be refunded at the end of the policy term to
the extent that no claims are made.

         The Company presently has in effect a $10,000,000 policy of Directors
and Officers liability insurance at an annual premium cost of $121,000.

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

                  (iii) To include any material information with respect to the
         plan of distribution not previously disclosed in this registration
         statement or any material change to such information in this
         registration statement; provided, however, that paragraphs (a)(1)(i)
         and (a)(1)(ii) do not apply if the information required to be included
         in a post-effective amendment by those paragraphs is contained in
         periodic reports filed with or furnished to the SEC by the Registrant
         pursuant to Section 13 or 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.

         (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.

Provided, however, That paragraphs (a)1(i) and (a)(1)(ii) of this section 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 those
paragraphs is contained in periodic reports filed with or furnished to the
Commission by the registrant pursuant to Section 13 or Section 15(d) of the
Securities Exchange Act of 1934 that are incorporated by reference in the
registration statement.
         (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 Exchange
Act and that is incorporated by reference in the registration statement shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

         (c) Insofar as indemnification for liabilities arising under the
Securities Act 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 SEC 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.
